Herberg, General Manager Originator: Kelly A. Lore, Clerk of the Board SUBJECT: 2017 CONFLICT OF INTEREST CODE GENERAL MANAGER'S RECOMMENDATION Adopt Resolution No. OCSD 17-03 entitled, "A Resolution of the Board of Directors of Orange County Sanitation District adopting a Conflict of Interest Code which supersedes all prior Conflict of Interest Codes and amendments previously adopted" BACKGROUND The last biennial review, and formal amendment, to the District's Conflict of Interest Code was completed in February of 2016. Although the Political Reform Act requires that every local agency review its Conflict of Interest Code biennially (which would bring forth the next amendment in 2018), staff is proposing this new amendment in order to reflect the current positions of those designated employees that are required to file statements of economic interests RELEVANT STANDARDS • Political Reform Act, Government Code Sections 81000, et seq • Califomia Government Code Section 87300-87306 • Fair Political Practices Commission (2 Cal. Code of Regs. Section 18100, et seq.) PROBLEM With the reorganization of the District workforce, two designated employee positions will be eliminated; two designated employee positions will be created; and one designated employee position was reclassified into an already existing designated position. All positions are required to file statements of economic interest. PROPOSED SOLUTION Staff recommends that the Board of Directors adopt the updated 2017 Conflict of Interest Code to reflect the following changes: • Deletion of Principal Public Affairs Specialist (effective February 17, 2017) • Deletion of Public Affairs Manager(effective February 17, 2017) • Addition of Public Affairs Supervisor (effective February 17, 2017) • Addition of Maintenance Superintendent (new position) • Deletion of Environmental Compliance & Regulatory Affairs Manager (reclassified to Engineering Manager Page 1 of 2 If approved by the Board, the newly approved code will be forwarded to the County of Orange for amendment approval. TIMING CONCERNS The changes in position control have taken place, and therefore cannot wait until a future meeting. RAMIFICATIONS OF NOT TAKING ACTION Non-compliance with state law. PRIOR COMMITTEE/BOARD ACTIONS February 2016— Board of Directors amended the Conflict of Interest Code and approved Resolution No. OCSD 16-02.

Herberg, General Manager Originator: Rob Thompson, Director of Engineering SUBJECT: CAPITAL IMPROVEMENT PROGRAM CONTRACT PERFORMANCE REPORT GENERAL MANAGER'S RECOMMENDATION Receive and file the Capital Improvement Program Contract Performance Report for the period ending December 31, 2016. BACKGROUND The Capital Improvement Program involves awarding and managing many construction and consulting contracts. In 2008, the Orange County Sanitation District (Sanitation District) Board of Directors began awarding contingencies along with construction and consulting contracts. The contingencies allow the General Manager to approve change orders for construction contracts and amendments for consulting contracts up to the amount of the approved contingency. This practice reduces administrative costs, expedites resolution of project issues that arise, helps avoid contractor delay claims, and facilitates efficient management of many contracts. The Capital Improvement Program Contract Performance Report summarizes construction and consulting contract performance and activities for the quarter ending December 31, 2016. This report will be updated quarterly. RELEVANT STANDARDS • Ensure the public's money is wisely spent ATTACHMENT The following attachments)are included in hard copy and may also be viewed on-line at the OCSD website (www.ocsd.coml with the complete agenda package: • Capital Improvement Program Contract Performance Report for the period ending December 31, 2016 JM:gc Page 1 of 1 ORANGE COUNTY SANITATION DISTRICT Capital Improvement Program Contract Performance Report For the period ending December 31, 2016 DATE: January 25, 2017 TO: Orange County Sanitation District Board of Director FROM: James D. Herberg, General Manager Through: Rob Thompson, Director of Engineering This report summarizes the status, activities, and performance of public works construction contracts and agreements with design consultants. PART 1 - CONSTRUCTION CONTRACTS When the Orange County Sanitation District (Sanitation District) Board awards a construction contract, a contingency is also approved which allows the General Manager to approve contract change orders up to the amount of the contingency. One of the purposes of this report is to document how that contingency is managed and how much of the contingency is utilized.A project's change order rate can only be documented when the work is complete. As such, the change order performance charts in this report are based only on projects closed since the Board began approving contingencies in 2008.

PDSAs are used to obtain design engineering services, and PCSAs are a subsequent agreement with the design consultant to provide support services during construction. Master PDSAs are issued to a pool of 12 pre-qualified consultants to be used for smaller projects. On those smaller projects, the Sanitation District solicits task order proposals from three or four of the firms, and awards a task order to the most qualified consultant. There are currently three sets of Master PDSAs, including sets from 2009, 2012, and 2015.

Approve Cooperative Agreement between the Orange County Sanitation District and the City of Anaheim for water supply pipe replacement on State College Boulevard along portions of the Newhope-Placentia Trunk Replacement, Segment B, Contract No. 2-7213, for an estimated amount of $1,300,000 to be reimbursed by the City of Anaheim; B. Approve a budget increase of $1,300,000 for the Newhope-Placentia Trunk Replacement, Project No. 2-72 for a total budget amount of$101,375,000; and C. Approve a contingency increase of $220,000 (3%) to the Professional Design Services Agreement with Lee & Ro, Inc. for the Newhope-Placentia Trunk Replacement, Project No. 2-72, for a for a total contingency of$1,066,823 (13%). BACKGROUND Newhope-Placentia Trunk Replacement, Segment B, Contract No. 2-7213, replaces the Newhope-Placentia Trunk with a larger sewer in State College Boulevard from the 91 Freeway to Orangewood Avenue, Anaheim. The project is currently undergoing final design. The design of the new sewer alignment requires the City of Anaheim (City)water lines be relocated at various locations. The City plans to replace these and additional water lines within the vicinity of the new sewer alignment. The Orange County Sanitation District (Sanitation District) and the City have concluded it would be beneficial for both entities and the public if this work occurred underthe same timeframe and underone construction contract. City and Sanitation District staff have negotiated a cooperative agreement. The agreement allows these City facilities to be designed and constructed by the Sanitation District. Sanitation District costs related to the design and construction of these City facilities will be reimbursed by the City. The estimated costs for the design and construction of these facilities is $1,300,000. RELEVANT STANDARDS Maintain collaborative and cooperative relationships with neighboring agencies Page 1 of 3 PROBLEM The Sanitation District needs to relocate City water lines for the proposed Newhope- Placentia Trunk alignment and the City has planned replacement projects for these water lines and plans four new sewer connections. Constructing these facilities separately would cost more and cause more public disruption. PROPOSED SOLUTION The Sanitation District will design and construct the water lines for the City. The City has agreed to reimburse the Sanitation District for the associated costs. TIMING CONCERNS The agreements require approval so the design of the City facilities can be incorporated into the Newhope-Placentia Trunk Replacement, Segment B, Contract No. 2-72B, without delaying the larger project. RAMIFICATIONS OF NOT TAKING ACTION Without the Cooperative Agreement, the City will need to perform their projects independently, which may conflict with Sanitation District work and increase impacts to the public. PRIOR COMMITTEE/BOARD ACTIONS September 2016 - Approved Cooperative Agreement between the Orange County Sanitation District and the City of Fullerton for street paving. February 2016 - Awarded a Construction Contract to Trautwein Construction, Inc. for Newhope-Placentia Trunk Sewer Replacement(Fullerton/Anaheim Segment A), Contract No. 2-72A, for a total amount not to exceed $21,134,650, and approved a contingency of $2,113,465 (10%). October 2014 -Approved a Professional Design Services Agreement with Lee & Ro, Inc. to provide engineering design services for Newhope-Placentia Trunk Replacement, Project No. 2-72, for an amount not to exceed $8,468,232. ADDITIONAL INFORMATION The Sanitation District approved a similar Cooperative Agreement with the City of Fullerton for street paving under the Newhope-Placentia Trunk Replacement, Segment A, Contract 2-72A. Page 2 of 3 CEQA The Sanitation District, as lead agency, prepared a Program Environmental Impact Report (PEIR) entitled 1999 OCSD Strategic Plan. The Board certified the PEIR on October 27, 1999. The Sanitation District filed a Notice of Determination on October 29, 1999. In February 2016, the Sanitation District received and filed an Addendum to the PER. FINANCIAL CONSIDERATIONS This request for increase in the Professional Design Services Agreement budget complies with authority levels of the Sanitation District's Purchasing Ordinance. This item has not been budgeted (Line item: Budget FY2016-17 & FY2017-18, Section 8, Page 21). As the additional costs associated with the design and construction will be reimbursed by the City, no additional funds are required for the Capital Improvement Program.

Daniel A. Ballin, Linda Andal, City Clerk Deputy City Attorney 120117 10 EXHIBIT A WATER PROJECTS DESCRIPTION PROJECT 2-72B Project consists of one 33 to 42-inch diameter sewer,which OCSD intends to upsize to a 54-inch diameter sewer, in State College Blvd from Orangewood Ave to the south to 91-Freeway to the north, known as"Project 2-72B". STATE COLLEGEILINCOLN AVENUE WATER PROJECT Project consists of the design and construction of approximately 800 linear feet of 12-inch diameter zinc-coated ductile iron water pipeline along State College Blvd to replace an a existing 6-inch diameter water main between Lincoln Avenue to the south and Underhill Avenue to the north. The new water main in this project is proposed to be upsized to 12-inch in order to improve the fire flow in this portion of Anaheim's water distribution system. Project to also include the replacement of existing system valves,fire hydrants, and services. STATE COLLEGE/LA PALMA AVENUE WATER PROJECT Project consists of the design and construction of approximately 1900 linear feet of 12-inch diameter water main along State College Blvd to replace an existing 6-inch diameter water main between Underhill Avenue to the south and La Palma Avenue to the north The new water main in this project is proposed to be upsized to 12-inch in order to improve the fire flow in this portion of Anaheim's water distribution system. Project to also include the replacement of existing system valves, fire hydrants,and services. STATE COLLEGE/BALL ROAD AVENUE WATER PROJECT Project consists of the design and replacement of approximately 400 linear feet of existing 12- inch cast iron and 18-inch CCP water mains with zinc-coated ductile iron pipe at the intersection of State College Boulevard and Ball Road. This project will increase the reliability of Anaheim's water distribution in this area. Existing system valves will also be removed and replaced with resilient wedge valves located outside of the intersection. MISCELLANEOUS OCSD RELOCATIONS WATER PROJECT Project consists of the design and replacement of various water mains as required for the installation of OCSD's Project 2-723. Approximate locations and limits of work are depicted on the next page. GENERAL NOTE The City of Anaheim's current design standards require that all water mains be 8-inch or larger. Therefore,existing 4-inch and 6-inch diameter water mains will not be allowed to be replaced in- kind but shall be upsized to 8-inch minimum Cost sharing calculations as discussed in the Agreement shall be based on a mimmum pipe size of 8-inch. 11 L '3Av 213 N0VM 3nV C700M30NVd0 '3L N AOr L2 �, Z C 3nV 1NOw83n T ~ Z N J D 'LS Hlnos f 8 '3nV v7131vN Isim 0 -DI m Z n y m A 8 '3nV 113MOH y Z O oz m m r m D 7 C m m C� � Dm 0 5 m N N = C m � y mMz 3 O z '3nV SOil2Ji130 m m 9 ']AV N100NI C Q D O ;a my mD * O 9 n D v m QZ IlIH83ONn p m Z "Cd NOISNIM m r ma> p no 1 1 z n Oa live '3nV VWIVd Vl � C F x mm M po z '60 VA3Nwoa � a z Z O 1 � 0 m '3nV 63NOVM AM3 66 OPERATIONS COMMITTEE M%1110,Date TOBd.of Dir. 03/01/17 03/22/17 AGENDA REPORT ItemNumber Item Number s s Orange County Sanitation District FROM: James D. Herberg, General Manager Originator: Rob Thompson, Director of Engineering SUBJECT: SLUDGE DIGESTER REHABILITATION AT PLANT NO. 1, PROJECT NO. P1-100 GENERAL MANAGER'S RECOMMENDATION Approve a contingency increase of $1,005,000 (3%) to the construction contract with J.R. Filanc Construction Company, Inc. for Sludge Digester Rehabilitation at Plant No. 1, Project No. P1-100, for a total contingency of$10,217,500 (30.5%). BACKGROUND The Orange County Sanitation District (Sanitation District) utilizes anaerobic digestion to stabilize and reduce biosolids generated from treating wastewater. The Sludge Digester Rehabilitation at Plant No. 1, Project No. P1-100, rehabilitates and improves solids handling capacity for 12 anaerobic digesters and digested sludge holding tanks at Plant No. 1. The project scope includes replacing the existing digester insulation and roofing material. The roofing material originally specified at the time of bid was no longer available on the market at the time of construction. The Contractor submitted an alternate material that was approved. Approximately one year after the first four digesters with the new roofing were placed back into service, staff noticed that the roofing was becoming slippery as the grit embedded in the roofing loosened. To address this concern, the Sanitation District found and installed an alternative cementitious roofing material on the remaining eight digesters. It is recommended that the same cementitious roofing material be placed on the initial four digesters, Digesters 7, 8, 9, and 10, to address slipping hazards, as the increased maintenance is no longer effective at maintaining a safe surface on these digesters. Staff has determined that the reroofing work at Digesters 7, 8, 9, and 10 can be performed under the P1-100 construction contract without delaying project completion. There is, however, insufficient remaining contract contingency to authorize the entire scope of this additional work. RELEVANT STANDARDS Ensure the public's money is wisely spent Provide a safe and collegial workplace Page 1 of 3 PROBLEM The roof surfaces of Digesters 7 through 10 can become slippery over time as grit becomes loose, especially when slightly moist, and could lead to falls. Replacing the roofing material to match the other digesters would mitigate this safety issue. The current remaining authorized contract contingency is not enough to perform the reroofing work. PROPOSED SOLUTION Increase the construction contract contingency by $1,005,000 (3%) from $9,212,500 (27.5%)to $10,217,500 (30.5%) to complete the roofing removal and replacement. This additional contract contingency will not require additional project budget. TIMING CONCERNS Delaying roofing replacement will continue the current significant slipping/fall hazard. In addition, the work must be authorized soon to avoid delaying completion of the current construction contract. If the work cannot be done under the current contract, additional costs would be incurred for another contractor to mobilize. RAMIFICATIONS OF NOT TAKING ACTION The reroofing work is not possible without additional construction contract contingency. Reroofing of the digesters would need to be performed under a separate construction contract, which would be more costly to the Sanitation District, would delay resolution of the safety concerns and risks, and would not be completed by Fall 2017. PRIOR COMMITTEE/BOARD ACTIONS October 2016 - Approved a budget increase of $500,000 for Sludge Digester Rehabilitation at Plant No. 1, Project No. P1-100, for a total budget amount of $67,150,000, and approved a contingency increase of $837,500 (2.5%) for a total contingency of$9,212,500 (27.5%). December 2014 - Approved a contingency increase of $4,355,000 (13%) to the construction contract, for a total contingency of$8,375,000 (25%). February 2013-Approved a contingency increase of$1,340,000 (4%)to the construction contract, for a total contingency of$4,020,000 (12%). February 2010 - Awarded a construction contract to J.R. Filanc Construction Company, Inc. for Sludge Digester Rehabilitation at Plant No.1, Project No. P1-100, for an amount not to exceed $33,500,000, and approved a contingency of$2,680,000 (8%). Page 2 of 3 ADDITIONAL INFORMATION The P1-100 project includes rehabilitation of twelve digesters (Digesters 5-16) at Plant No.1. These digesters were built between the years of 1959 and 1993. The construction contract incurred significant delays, primarily due to unknown conditions comprised of higher volumes and concentrations of residual solids, repairs of concrete cracks inside the digesters, repairs of existing pipe leaks, replacement of existing valves that could not be rehabilitated, and extensive PVC liner repair inside the digesters. Due to the cost and schedule impacts already incurred on the project, staff initially evaluated the option of performing the reroofing work at Digesters 7, 8, 9, and 10 under a separate project. After much evaluation, it was determined that adding the reroofing work to the P1-100 projectwill reduce overall cost, improve schedule implementation, and ensure that roofing material is consistent with the other eight digesters, which are performing properly. Staff met with the Contractor to evaluate the reroofing work and it was determined that the work could start immediately, would be less costly than under a separate project, and could be completed within the current completion date of Fall 2017. To address the slipping hazard as soon as possible, staff has authorized removal of the roofing for two of the four digesters with available contingency. Completing the work will need additional contingency. CEQA This project was included in the Secondary Treatment and Plant Improvement Project's Subsequent Environmental Impact Report(SEIR)to the 1999 Strategic Plan Program EIR prepared by Environmental Science Associates and certified on May 25, 2005. A Notice of Determination was filed on May 26, 2005. FINANCIAL CONSIDERATIONS This request complies with authority levels of the Sanitation District's Purchasing Ordinance. This item has been budgeted (FY2016-17 and 2017-18, Section 8, Page 49), and the budget is sufficient for the recommended action.

OPERATIONS COMMITTEE Melting D310 TOBE.Or Dir. 03/01/17 03/22/17 AGENDA REPORT Item Item Number 6 9 Orange County Sanitation District FROM: James D. Herberg, General Manager Originator: Rob Thompson, Director of Engineering SUBJECT: DOIG DRIVE BUILDING DISPOSAL GENERAL MANAGER'S RECOMMENDATION Direct staff to dispose of Orange County Sanitation District property at 7311 Doig Drive through sale or exchange and return to the Board of Directors in a future closed session to receive price and terms direction. BACKGROUND In 2005, the Orange County Sanitation District (Sanitation District) purchased the building located at 7311 Doig Drive in Garden Grove to be used as a Collections Department field office. However, as a result of local sewer transfers in the cities of Costa Mesa, Newport Beach, Orange, Tustin, and unincorporated areas of Orange County, it was later determined that the new facility was no longer necessary and the building was declared surplus property. A decision was made to lease the building out. The building is currently under a lease with a manufacturing firm that guarantees extensions until 2022. The building was constructed in 1975 per seismic codes less stringent than currently required. A Seismic Risk Assessment was performed and structural reinforcements were recommended to meet current seismic standards. RELEVANT STANDARDS • Protection of Orange County Sanitation District assets PROBLEM The building does not meet current seismic standards and is not necessary for Sanitation District operational needs. PROPOSED SOLUTION Dispose of this asset through sale or exchange. TIMING CONCERNS The ownership and management of this property is not necessary and represents a distraction from Sanitation District core business. In addition, the building represents a risk for structural damage due to an earthquake. Page 1 of 2 RAMIFICATIONS OF NOT TAKING ACTION The building may be subject to significant damage and subsequent repair costs during an earthquake if seismic strengthening is not performed. PRIOR COMMITTEE/BOARD ACTIONS November 2016 -Approved the Second Amendment to the Doig Property Lease to enter into an eight-month lease extension of the Sanitation District's real property at 7311 Doig Drive, Garden Grove, in a form approved by General Counsel. July 2016 - Board of Directors approved First Amendment to extend the lease by three months. December 2011 - Board of Directors authorized the lease at 7311 Doig Drive. November 2010 - Board of Directors declared the property at 7311 Doig Drive as surplus property. CEQA Not applicable for disposing of Doig Drive building. FINANCIAL CONSIDERATIONS The proceeds of this asset disposal may be used to offset other property acquisitions by the Sanitation District.

Herberg, General Manager Originator: Rob Thompson, Director of Engineering SUBJECT: INTERIM FOOD WASTE RECEIVING FACILITY RESOLUTIONS SUPPORTING GRANT APPLICATIONS, PROJECT NO. P2-124 GENERAL MANAGER'S RECOMMENDATION A. Adopt Resolution No. OCSD 17-04 entitled: "A Resolution of the Board of Directors of the Orange County Sanitation District authorizing submittal of an application for CalRecycle Organics Program Grant"; and B. Adopt Resolution No. OCSD 17-05 entitled: "A Resolution of the Board of Directors of the Orange County Sanitation District authorizing submittal of an application by Waste Management, Inc. on behalf of the Orange County Sanitation District for the Fourth Cycle Regional Recycling and Waste Reduction Grant for the Orange County Food to Families— Food to Energy Organics Diversion Program Grant." BACKGROUND The Orange County Sanitation District (Sanitation District) utilizes anaerobic digestion to stabilize and reduce biosolids generated from treating wastewater. The process also produces a methane-rich digester gas which is burned in engine generators at both Plant No. 1 and Plant No. 2 to supply approximately 60% of the plants' power requirements. The State of California is implementing regulations to divert organic material, typically food waste,from landfills, with the intention of extending the lives of landfills and reducing greenhouse gases generated as the organic material decays. As a result, waste haulers, such as Waste Management Inc., Republic Services, and CR&R Incorporated, are seeking options for disposal or reuse of food waste. Last month, the Sanitation District Board of Directors approved the Interim Food Waste Receiving Facility, Project No. P2-124, to construct a facility at Plant No. 2 to receive processed food waste to be fed to the anaerobic digesters and generate digester gas. The costs of this project are expected to be offset by tipping fees charged to the food waste haulers, and by electricity generated from the additional digester gas production. Staff is currently pursuing two opportunities for grant funding related to the project. On March 9, 2017, the California Department of Resources Recycling and Recovery (CalRecycle) will accept grant applications for their Organics Grant Program (FY 2016-2017). This grant could provide up to $3.2 million. To receive this grant, the Sanitation District Board of Directors must adopt a resolution supporting the application. Page 1 of 3 Orange County Waste & Recycling is also offering grants under its Fourth Cycle Regional Recycling and Waste Reduction Grant program. To obtain this funding, a group of cities, the county, a non-profit organization, and Waste Management Inc., are planning to participate in the Orange County Food to Families — Food to Energy Organics Diversion Program. Waste Management Inc. is taking the lead on submitting the application. Because multiple areas of the county are covered, the group could receive more than the $600,000 limit per Supervisorial District. Any allocated grant funds would be split among the parties. The amount of the grant the Sanitation District would receive is not known at this time. The deadline forthe Orange County Waste&Recycling grant application is May 19, 2017. This grant also requires a resolution to be adopted. In this case, the resolution also includes the Sanitation District in the County's Orange County Food to Families — Food to Energy Organics Diversion Program. Participation in the food-waste recycling would be the extent of the Sanitation District's participation in the program. RELEVANT STANDARDS • Ensure the public's money is wisely spent • Maintain collaborative and cooperative relationships with neighboring agencies • Use all practical and effective means for recovering energy PROBLEM Resolutions must be adopted by the Sanitation District Board of Directors to support grant applications related to the Interim Food Waste Receiving Facility, Project No. P2-124. PROPOSED SOLUTION Adopt the attached resolutions. TIMING CONCERNS The resolution supporting the CalRecycle grant must be adopted by the Board of Directors in March. The resolution supporting the Orange County Waste & Recycling grant applications must be adopted by the Board of Directors in April 2017. RAMIFICATIONS OF NOT TAKING ACTION Failure to adopt these resolutions would likely result in the grant application being rejected. PRIOR COMMITTEE/BOARD ACTIONS February 2017 - Established a project for Interim Food Waste Receiving Facility, Project No. P2-124, with a budget of$5,400,000. Page 2 of 3 ADDITIONAL INFORMATION N/A CEQA The Interim Food Waste Receiving Facility, Project No. P2-124, will require CEQA documentation, which will be completed as part of the Biosolids Master Plan, Project No. PS15-01. FINANCIAL CONSIDERATIONS This request complies with authority levels of the Sanitation District's Purchasing Ordinance. The budget for the project Interim Food Waste Receiving Facility, Project No. 132-124, was approved at the February 2017 Board of Directors meeting.

Herberg, General Manager Originator: Rob Thompson, Director of Engineering SUBJECT: REHABILITATION OF WESTERN REGIONAL SEWERS, PROJECT NO. 3-64 GENERAL MANAGER'S RECOMMENDATION A. Consider, receive, and file the Final Environmental Impact Report for the Rehabilitation of Western Regional Sewers, Project No. 3-64, dated March 22, 2017; and B. Adopt Resolution No. OCSD 17-06, entitled: "A Resolution of the Board of Directors of the Orange County Sanitation District Certifying the Environmental Impact Report for the Rehabilitation of the Western Regional Sewers, Project No. 3-64; Adopting the Corresponding Statement of Overriding Considerations and the Mitigation Monitoring Program; and Approving the Western Regional Sewers, Project No. 3-64. BACKGROUND The Orange County Sanitation District (Sanitation District) owns and maintains regional conveyance facilities in the Cities of Los Alamitos, Cypress, La Palma, Buena Park, Anaheim, Seal Beach, and Rossmoor, an unincorporated area of the County of Orange. The facilities include the Orange Western Subtrunk, Los Alamitos Subtrunk, West Side Relief Interceptor, Seal Beach Interceptor, and the Westside Pump Station. Many of the sewers range in age from 40 to 60 years and require mid-life refurbishment to attain their full-service life. RELEVANT STANDARDS • Listen to and seriously consider community input on environmental concerns • Meet CEQA and NEPA standards • Operate and maintain facilities to minimize impacts on surrounding communities, including odor, noise, and lighting • 24/7/365 treatment plant reliability • Less than 2.1 sanitary sewer spills per 100 miles • Meet or exceed sanitary sewer overflow regulations PROBLEM Nearly 17 miles of sewers in the northwest corner of the Sanitation District's service area require rehabilitation or replacement. Page 1 of 3 Many segments of the sewers need rehabilitation or replacement due to calcium blockage, structural deterioration, and groundwater infiltration. Other segments are undersized. The West Side Pump Station wet well and force main also have corrosion damage that should be repaired. PROPOSED SOLUTION This project will remove calcium deposits inside the sewer pipes that currently restrict flow and prevent cleaning of some sewer segments. Deteriorated pipes and manholes will be lined or replaced to reduce inflow and infiltration and to protect against further corrosion. Several segments of the sewers will be replaced with larger diameter pipes to carry more flow. The project will replace the Westside Pump Station wet well, line its force main, and install an odor treatment facility. TIMING CONCERNS The schedule driver of this project is to resolve the safety and reliability risks associated with deteriorated and under-capacity facilities to reduce the risks of spills and structural failures. RAMIFICATIONS OF NOT TAKING ACTION The project cannot proceed without this environmental finding. PRIOR COMMITTEE/BOARD ACTIONS January 2016 — Approved a Professional Design Services Agreement with AECOM Technical Services, Inc. for Rehabilitation of Western Regional Sewers, Project No. 3-64, for an amount not to exceed $17,639,250, and approved a contingency of $1,763,925 (10%). ADDITIONAL INFORMATION The project is currently in the preliminary design phase and scheduled to be transitioning into final design phase by September 2017. Final design is planned to be completed in January 2019 with advertising and bidding by March 2019. Construction will start in August 2019 and is expected to be completed by March 2025. CEQA The Sanitation District, as lead agency, prepared an Initial Study analyzing the Project's potential environmental impacts. Based on the Initial Study, it was determined that an Environmental Impact Report was the appropriate CEQA document to prepare. On this basis, a Notice of Preparation (NOP) was prepared and made available for a 30-day public review period from November 30, 2015 to December 29, 2015. The NOP was also submitted to the State Clearinghouse (State Clearinghouse No. 2015111077). Page 2 of 3 A Draft Environmental Impact Report (Draft EIR)was developed and distributed for a 45- day public review period from October 17, 2016 to December 1, 2016. A public hearing was held on November 17, 2016. The Final Environmental Impact Report (Final EIR) found that while certain impacts can be mitigated to less than significant levels, the project will potentially result in significant and unavoidable impacts to temporary increases in ambient noise levels during construction. For this reason, a statement of Overriding Considerations identifying the project's expected benefits has been prepared. The Sanitation District received seven comments on the Draft EIR, which are included as Section 8.0 of the Final EIR. The comments were from public agencies as well as members of the public and ranged from traffic routing to emergency response pre- notification to requesting an on-site Native American monitor during all construction activity that disturbs the ground. Pursuant to CEQA Guidelines Section 15088(c), the Final EIR includes written responses to those comments (Section 8.0). The proposed Resolution making CEQA findings and adopting the Final EIR, Mitigation Monitoring and Reporting Program, and Statement of Overriding Considerations (if applicable) is attached for the Board of Directors consideration and approval.

("CEQA")) and the CEQA Guidelines (California Code of Regulations, Title 14, Sections 15000 et seq.), the District prepared a Draft Environmental Impact Report ("DEIR") (State Clearinghouse Number 2015111077) that reflected the independent judgment of the District as to the potential environmental impacts of the Project. The DEIR determined that certain aspects of the Project would have significant impacts on the environment that cannot be mitigated and therefore the District prepared a Statement of Overriding Considerations identifies applicable mitigation measures; and WHEREAS, the District consulted with other public agencies and the general public, and provided such agencies and the public with the opportunity to provide written and oral comments on the Project and the DEIR as required by CEQA, including a public review period of 45 days, which commenced on October 17, 2016, and ended on December 1, 2016; and OCSD 17-06-1 1229 3.1 WHEREAS, on November 17, 2016, District staff held a public meeting to provide a further opportunity for public agencies and the general public to comment on the DEIR; and WHEREAS, the District has reviewed the comments received and has responded in the Final Environmental Impact Report to all significant environmental issues raised during the review and consultation process; and WHEREAS, the comments received on the DER, either in full or in summary, together with the District's responses have been included in the Final Environmental Impact Report for the proposed Project; and WHEREAS, the Final Environmental Impact Report, including the comments received by the District on the Draft Environmental Impact Report, has been presented to the District's Board of Directors (the "Board") for review and consideration prior to the approval of, and commitment to, the Project, and the certification of the Final Environmental Impact Report, approval of the Mitigation Monitoring Program and the Statement of Overriding Considerations is consistent with the provisions of CEQA. NOW, THEREFORE, the Board of Directors of the Orange County Sanitation District, DOES HEREBY RESOLVE, DETERMINE AND ORDER: Section 1. The Board of Directors certifies that the Final Environmental Impact Report, attached to this Resolution as Exhibit A, including comments and responses thereto, and related technical appendices, have been completed in compliance with CEQA and are a complete and adequate description of the environmental conditions of the proposed Project.

The proposed Project includes rehabilitation of the Orange-Western Sub-trunk and the Seal Beach Boulevard (Blvd.) Interceptor pipelines, rehabilitation and/or replacement of the Los Alamitos Sub-trunk and the Westside Relief Interceptor pipelines, rehabilitation or replacement of the Westside Pump Station force main, replacement of the Westside Pump Station wet well, and addition of either an air scrubber or airjumper line at the Westside Pump Station (Figure ES-1). These sewer lines are located in the westernmost portion of the OCSD service area and are referred to collectively throughout this document as the Western Regional Sewers. Collectively, the Los Alamitos Sub-trunk, the Westside Relief Interceptor, and the Seal Beach Blvd. Interceptor convey sewage flows from the City of Seal Beach, the community of Rossmoor in unincorporated Orange County, the City of Los Alamitos, the City of Cypress, the City of La Palma, and other areas in the vicinity of the Westside Pump Station.The Orange-Western Sub-trunk conveys flows from the Cities of Cypress, Buena Park, and Anaheim to the Miller Holder Trunk and the Knott Interceptor. The Orange-Western Sub-trunk is not tributary to the Westside Pump Station. Sewage flow from all Project components ultimately is directed to OCSD Treatment Plant No. 2 located at 22212 Brookhurst Street in Huntington Beach. ES-3 Project Location Los Alamitos Sub-trunk: The Los Alamitos Sub-trunk (Figure ES-1), constructed in 1959, is 34,620 feet long and has 90 manholes.The pipe diameter ranges in size from 18 to 30 inches.Approximately 15,540 feet of the Los Alamitos Sub-trunk are capacity deficient and require an increase in the size of the pipe (Figure ES-2). The Los Alamitos Sub-trunk is within the following cities: La Palma (La Palma Avenue and Denni Street), Cypress (Denni Street, Guardian Drive, Orange Avenue, Bloomfield Avenue, and Bloomfield Street), Los Alamitos (Bloomfield Street, West Cerritos Avenue, Chestnut Street, Sausalito Street, Oak Street, Katella Avenue, and Los Alamitos Boulevard), Seal Beach (Seal Beach Boulevard and Old Ranch Parkway),and the community of Rossmoor(3112 Yellowtail Drive). Westside Relief Interceptor: The Westside Relief Interceptor (Figure ES-1) was constructed under two contracts in 1959 and 1976. This line is approximately 32,100 feet long with 81 manholes. Pipe size ranges from 15 to 39 inches in diameter. Approximately 16,010 feet of the Westside Relief Interceptor are capacity deficient and require an increase in the size of the pipe (Figure ES-2). The Westside Relief Interceptor is within the following cities: La Palma (Crescent Avenue and Moody Street), Cypress (Moody Street, Orange Avenue, and Denni Street), Los Alamitos (Denni Street, Katella Avenue, and Los Rehabilitation of Western Regional Sewers, Project 3-64 ES-3 Executive Summary Alamitos Boulevard), and Seal Beach (Seal Beach Boulevard and Old Ranch Parkway). The Los Alamitos Sub-trunk and the Westside Relief Interceptor are physically connected at the intersection of Orange Avenue and Denni Street by Diversion No.65. Westside Pump Station: The Westside Pump Station is located at 3112 Yellowtail Drive in the community of Rossmoor in unincorporated Orange County. The pump station underwent a major reconstruction in 2008 (Project 3-52). At that time,the existing pump station was rehabilitated to meet then-current OCSD standards and national and state codes. In addition, the station's capacity was increased to meet the then-projected peak wet-weather flows. This included modification of the ventilation systems,control systems, and the station's structure and isolation of the pump and electrical rooms from one another. The mechanical equipment, which was previously located above ground, was moved 30 feet below ground. The building underwent some minor modifications, and the roof was upgraded. The front gate was moved to the east of the property to ease access into the pump station. Additional landscaping was installed to enhance the front of the facility. During this project, extensive degradation of the wet well was discovered; and repairs were made to bring the wet well back into service.The repairs to the wet well were intended to extend the life of the wet well another 10 to 15 years. The pump station receives sewage flows from the Los Alamitos Sub-trunk, the Westside Relief Interceptor, portions of Leisure World, and the Rossmoor/Los Alamitos area. The pump station discharges into the Seal Beach Blvd. Interceptor via a 150-foot-long, 20-inch-diameter force main that was installed in 1995 under Project No.3-36R.The facility has an air vent along the force main alignment that was abandoned and is no longer connected to the pump station.A Vapex Odor Control unit located on top of the wet well (part of Project No. 3-52) has been disconnected from service. The Seal Beach Blvd. Interceptor conveys all the flow from the Westside Pump Station to the Seal Beach Pump Station. Orange-Western Sub-trunk: The Orange-Western Sub-trunk (Figure ES-1), constructed in 1959, is 13,940 feet long and has 38 manholes.The pipe is 21 inches in diameter.The Orange-Western Sub-trunk consists of two segments.The first segment begins just north of the intersection of Crescent Avenue and Western Avenue in the City of Buena Park.The pipeline continues south on Western Avenue and turns west on West Orange Avenue before connecting to the Knott Interceptor. The second segment continues west on West Orange Avenue from the Knott Avenue intersection to the Miller Holder Trunk Sewer at the Valley View Street intersection. Seal Beach Blvd. Interceptor: The Seal Beach Blvd. Interceptor (Figure ES-1), constructed in 1970, is 5,530 feet long and has 8 manholes.The pipe is 51 inches in diameter.The Seal Beach Blvd. Interceptor begins just south of the Westside Pump Station at the end of Old Ranch Parkway in the City of Seal Beach.The pipeline continues south across the Interstate 405 (1-405) freeway right-of-way and in North Gate Road south of the 1-405 freeway until merging with Seal Beach Boulevard. The pipeline then continues south in Seal Beach Boulevard until it reaches the Seal Beach Pump Station located at the Rehabilitation of Western Regional Sewers, Project 3-64 ES-4 Executive Summary intersection of Seal Beach and Westminster boulevards.The Seal Beach Naval Weapons Station extends to the centerline of Seal Beach Boulevard.Approximately 3,500 feet of Seal Beach Blvd. Interceptor is on an easement on Navy land. ES-4 Purpose and Objectives The Western Regional Sewer pipelines have exceeded their functional life and have developed deficiencies that have led to the intrusion of groundwater and, in some cases, hard calcium deposits which make the pipe hard to clean and impede the wastewater flow. Also, portions of both the Los Alamitos Sub-trunk (15,540 linear feet) and the Westside Relief Interceptor (16,010 linear feet) are considered capacity deficient, are unable to handle projected 2040 wet weather flows, and need to be upsized to minimize the existing surcharging potential. Further,the Westside Pump Station wet well was repaired in 2008 to extend its serviceable life. The repairs to the wet well are nearing the end of their expected life,and the wet well needs to be replaced. The purpose of the proposed Project is to increase the life of the Western Regional Sewers within the Western Region of OCSD's service area by another 50 years and to ensure that the projected 2040 wet weather peak flows are adequately contained. Objectives for the proposed Project include the following: • Extend the service life of the Western Regional Sewers by either rehabilitation of the existing lines or replacement of the lines on a new alignment within the same streets • Replace the Westside Pump Station wet well to prevent potential for future failure and release of sewage to the environment • Accommodate projected 2040 wet weather peak flows(10-Year Storm) • Minimize impacts to the environment • Minimize existing surcharging in new/rehabilitated pipes • Minimize groundwater intrusion in new/rehabilitated pipes • Reduce potential for odors Without the Rehabilitation of the Western Regional Sewers and the Westside Pump Station improvements, groundwater intrusion and the potential for surcharging would continue and the wet well would further degrade. Additionally, OCSD would not meet requirements to accommodate projected 2040 wet weather flows, potentially resulting in unplanned sanitary sewer releases to the environment. ES-5 Project Description As described in detail in Chapter 2.0, the proposed Project includes the following main elements (Figure 2.4-3): (1) rehabilitation of portions of the Western Regional Sewers pipelines and manholes, Rehabilitation of Western Regional sewers, Project 3-64 ES-5 Executive Summary (2) replacement of portions of the Western Regional Sewers pipelines and manholes, and (3) improvements to the Westside Pump Station. Pipeline rehabilitation would consist of lining the existing pipe or manhole. Pipeline replacement would consist of installing new, larger diameter pipelines within the Project area. Pump station improvements would consist of replacement of the wet well and rehabilitation or replacement of the force main, as well as installation of an air scrubber or air jumper line for odor control and a new vent stack which would not exceed 20 feet in height. E8.6 Construction The proposed Project scope is based on preliminary planning data. OCSD has retained an engineering consultant to verify the preliminary planning data. The impact analysis in Chapter 3.0 of the Draft EIR assumes open-cut trench construction for all pipe replacement areas(see Figure 2.4-3 and Figure 2.4-4), except where otherwise noted, such as at all Orange County Flood Control District (OCFCD) facilities or other drainage channels, from near Willow Street/Denni Street through to Denni Street (i.e., between the residences and beneath the Pacific Electric right-of-way and Denni Street Park). These sections would use trenchless construction methods to replace the pipe. Although various trenchless methods are available, as discussed in Section 2.5.3, Cured-in-place pipe (CIPP) was evaluated in this EIR as representative of trenchless rehabilitation methods which could be used that would meet Project objectives(see Figure 2.4-3, Figure 2.4-4,and Section 2.5.3). Although the EIR generally assumes open-cut trench construction as the reasonable worst-case scenario for purposes of analyzing the project's potential impacts, it should be noted that OCSD is committed to minimizing impacts to the community and the environment through the use of trenchless construction methods where feasible. Trenchless technologies tend to have fewer impacts than open-cut trenching. For example, trenchless construction techniques generally entail shorter construction periods, require fewer pieces of construction equipment, and involve smaller construction areas when compared to open-cut trenching construction methods. However, trenchless methods are not always an option; soil condition, existing utilities, etc. can interfere with or preclude the use of trenchless methods. For the purposes of disclosure, various trenchless construction methods/approaches are discussed in the following subsections. Final decisions about which construction methods will be utilized would be made upon completion of design,alignment selection,and geotechnical evaluations. Other components of construction include repair or rehabilitation of sewer manholes, reconnection of local sewers, and abandonment of old lines. Subsequent to installation of the new pipe or rehabilitation of existing pipe, local and permitted connections to the mainline would be rejoined. In locations where non-permitted connections exist or where private laterals are connected directly to an OCSD sewer, a new local connection/system would be constructed and reconnected in accordance with OCSD policy, which requires private laterals/connections to be connected to a city- or county-owned manhole or pipeline prior to being connected to an OCSD manhole or pipeline. Subsequent to construction of the new pipe,the existing pipe and manholes would be abandoned in place and filled with concrete slurry. Rehabilitation of Western Regional Sewers, Project 3-64 ES-6 Executive Summary It is currently anticipated that construction of the proposed Project would occur from March 2019 through March 2023. As discussed in Section 2.5.3 Construction Schedule and Cost, the construction schedule allows sufficient time (approximately 4 years or 1,460 days)to construct each Project segment sequentially; however, construction activities are anticipated to last for approximately 24 to 30 months during this 4-year time frame. The 24- to 30-month time frame is anticipated due to overlapping construction activities for some Project segments. Construction of the proposed Project is discussed in more detail in Chapter 2.0. ES-7 Summary of Impacts The proposed environmental mitigation measures for significant impacts are discussed in detail in Chapter 3.0 in the following Sections: 3.1.5 (Aesthetics), 3.2.5 (Air Quality), 3.3.5 (Biological Resources), 3.4.5 (Cultural Resources), 3.7.5 (Hazards and Hazardous Materials), 3.8.5 (Land Use and Planning), and 3.9.5 (Noise). No impacts or less than significant impacts were identified for Geology and Soils (3.5), Greenhouse Gas Emissions (3.6), Public Services (3.30), Recreation (3.11), and Traffic and Circulation (3.12).Table ES-1 provides a list of significant impacts,the corresponding mitigation measures identified in Chapter 3.0, and the level of significance after mitigation. Implementation of these mitigation measures will be monitored and enforced in accordance with CEQA Guidelines Section 15097. All mitigation measures included in this EIR will be contractually imposed on the contractor and monitored by OCSD.A Mitigation Monitoring and Reporting Program has_been prepared along with the Final EIR and will includes all mitigation measures and implementation details.

ES.8 Alternatives CEQA requires that an EIR describe a range of reasonable alternatives to the project, or to the location of the project, which would feasibly attain most of the basic objectives of the project (CEQA Guidelines Section 15126.6). Based on the purpose and objectives specified for the proposed Project in Section 2.3, only build alternatives utilizing existing public rights-of-way and OCSD easements have been considered within this Draft EIR. Build alternatives associated with the construction of new pipelines and associated facilities lying outside existing street rights-of-way and easements would result in increased environmental impacts due to: (1) constraints imposed by the need to serve existing local sewer connections, (2) substantial increases in excavation required to accommodate new pipelines and new routes,and (3)the potential need for construction of additional pump stations. As described in Section 2.5, OCSD is committed to minimizing impacts to the community and the environment through the use of trenchless construction methods where feasible; however, for the purposes of evaluating a reasonable worst-case scenario for potential pipeline replacement impacts in this Draft EIR, trenchless construction methods are only assumed at all OCFCD facilities or other drainage channels and near Willow Street/Denni Street through to Denni Street (i.e., between the residences and beneath the Pacific Electric right-of-way and Denni Street Park). OCSD has identified two reasonable and feasible approaches to the proposed Project that would attain the Project's stated objectives.The two alternatives are: Rehabilitation of Western Regional Sewers, Project 3-64 ES-21 Executive Summary • Build Alternative 1 would replace portions of the existing Los Alamitos Sub-trunk and the Westside Relief Interceptor with new, larger capacity pipe. This build alternative also would rehabilitate portions of the existing Los Alamitos Sub-trunk and the Westside Relief Interceptor sewer pipe in place. In addition, Build Alternative 1 would rehabilitate the Orange-Western Sub- trunk and the Seal Beach Blvd. Interceptor pipelines in place. Further, Build Alternative 1 would rehabilitate the Westside Pump Station force main and wet well. • Build Alternative 2 would replace the entire Los Alamitos Sub-trunk pipeline with new, larger capacity pipe. This build alternative also would divert all flow from the Westside Relief Interceptor north of Orange Avenue to an enlarged Los Alamitos Sub-trunk via a new diversion structure. In addition, Build Alternative 2 would rehabilitate the entire length of the Westside Relief Interceptor, as well as the Orange-Western Sub-trunk and the Seal Beach Blvd. Interceptor pipelines, in place. Further, Build Alternative 2 would rehabilitate the Westside Pump Station force main and wet well. While the preceding two build alternatives take different approaches to meeting the proposed Project objectives,they also have certain elements in common: • Both build alternatives would entail rehabilitation of the Orange-Western Sub-trunk and the Seal Beach Blvd. Interceptor pipelines. • Manholes associated with these pipelines would be replaced or rehabilitated as appropriate. • Both Build Alternatives 1 and 2 would entail rehabilitation or replacement of the Westside Pump Station force main and replacement of the wet well, as well as installation of an air scrubber or airjumper line for odor control. ES.q Environmentally Superior Alternative Based on the analysis in this 8F2ft EIR,the "environmentally superior alternative,"as that term is used in CECA, is the No Build Alternative. If, as is the case with the proposed Project, the environmentally superior alternative is the No Build Alternative, CEQA Guidelines Section 15126.6(e)(2) requires identification of an environmentally superior alternative among the other alternatives. As discussed in Section 2.3, the purpose of the proposed Project is to extend the service life of the regional sewer system. Although both of the build alternatives would result in temporary significant construction impacts, both would meet all of the project objectives, including accommodating 2040 wet weather flows (10-Year Storm), which would minimize existing surcharging in new/rehabilitated pipes and minimize any potential for releases of sewage to the environment. On the basis of the analyses presented in Chapter 3.0, of the two alternatives considered, Build Alternative 1 is considered to be environmentally superior to Build Alternative 2 due to its lower potential for construction-related impacts associated with air quality, noise, and traffic. As discussed in Section 3.2 Air quality, construction emissions (criteria pollutants and greenhouse gases) under Build Alternative 1 (e.g., 15.47 pounds per day[lbs./day] of PM,o and 153.85 metric tons of greenhouse gases, Rehabilitation of Western Regional Sewers, Project 3-64 ES-22 Executive Summary or 153.16 metric tons CO2 equivalent amortized over a 30-year Project Life) are lower than those associated with Build Alternative 2 (19.92 lbs./day of PM,and 193.91 metric tons of greenhouse gases, or 191.89 metric tons CO2 equivalent amortized over a 30-year Project Life) because the increased emissions from the complete excavation/replacement of the Los Alamitos Sub-trunk under Build Alternative 2 would exceed the level of reduced emissions from the complete CIPP rehabilitation of the Westside Relief Interceptor. In a similar fashion, construction-related noise (Section 3.9) and traffic (Section 3.12) impacts are greater under Build Alternative 2 because of the prolonged construction period (75 additional construction days) and additional open-cut trenching (3,070 feet) required compared with Build Alternative 1. ES.10 Areas of Controversy Section 15123 (b)(2) of the CEQA Guidelines requires the Summary of an EIR to disclose areas of controversy known to the lead agency that have been raised by other agencies and the public. OCSD circulated a Notice of Preparation and Initial Study (NOP/IS) to solicit agency and public comments on the scope and environmental analysis to be included in the EIR. Copies of the NOP/IS and the NOP/IS comment letters received by OCSD are included in Appendix A to this EIR. A total of nine comment letters were received during the NOP/IS public review period.

Beginning on November 30, 2015, the NOP/IS was circulated for 30 days and mailed to interested parties, including local, state,and federal agencies.The NOP/IS was also submitted to the State Clearinghouse, along with a Notice of Completion (NOC). Copies of the NOP/IS were made available for public review at OCSD Administrative Offices (10844 Ellis Avenue, Fountain Valley, CA 92708) and at La Palma, Cypress, Los Alamitos/Rossmoor, Seal Beach/Mary Wilson, Buena Park, and Anaheim/Haskett public libraries. The NOP/IS was also made available for public review on OCSD's website:www.ocsd.com. The IS provided a general description of the facilities associated with the proposed Project, a summary of the probable environmental effects of the proposed Project to be addressed in the Draft EIR, and figures depicting the proposed Project location and proposed Project components.The NOP/IS provided the public agencies and interested parties with the opportunity to review the proposed Project and provide comments or concerns on the scope and content of the EIR.The NOP/IS comment period ended on December 29, 2015. Nine comment letters were received. The NOP/IS comment letters are presented in Appendix A of this the Draft EIR. This The Draft EIR addressed -""�••-- all of the issues raised in the NOP/IS comments. 1.2.2 Public Scoping Meeting CEQA recommends conducting early coordination with the public,appropriate public agencies, and local jurisdictions to assist in developing the scope of the environmental document. Pursuant to the CEQA Guidelines, Section 15083, a public scoping meeting was held at 10:00 a.m. on December 16, 2015, at the City of Cypress Community Center. In addition to the agencies notified through the State Clearinghouse, 64 potentially interested parties and agencies were mailed a copy of the NOP or the NOP/IS notifying them of the date, time, and location of the meeting. The scoping meeting was held to provide the public an opportunity to voice comments or concerns regarding potential effects of the proposed Project and the issues to be included in the Draft EIR. The meeting was attended by representatives from the City of Seal Beach and the Los Alamitos Unified School District. The comments received during the NOP review period were considered during preparation of this the Draft EIR. Issues not related to the scope of the proposed Project or environmental effects (e.g., Rehabilitation of Western Regional Sewers, Project 3-64 1-2 1.0-Introduction financing or economic factors)are were not addressed in the Draft EIR but may be considered by OCSD before making a final decision on the proposed Project. Please refer to Appendix A of the Draft EIR for comments received during the seeping period and information related to the circulation of the NOP. 1.2.3 Scope of the EIR Based on the analysis undertaken in the IS, OCSD determined that the proposed Project may have a significant effect on the environment and that the preparation of an EIR was required. As a result of the analysis within the IS (Appendix A), and in consideration of the comments received during the scoping comment period, it was determined that the proposed Project would result in no impacts to Agriculture and Forestry Resources, Mineral Resources, and Population and Housing.These environmental resource areas will receive no further analysis in this document. In addition,the IS determined that the proposed Project would have no potential to significantly impact other resource areas within the IS (aesthetics, biological resources, greenhouse gases, cultural resources, public services, and hazardous materials); however, the potential Project-related impacts to these resources are addressed further herein to provide additional information. The analysis in the IS concluded that the Project has the potential to result in significant impacts related to one or more significance criteria (see Appendix A)and required further consideration within the EIR.The following 42 13 environmental resource areas are the subject of this EIR: • Aesthetics • Air Quality • Biological Resources • Cultural Resources • Geology and Soils • Greenhouse Gas Emissions • Hazards and Hazardous Materials • Land Use and Planning • Noise • Recreation • Public Services • Traffic and Circulation • Tribal Cultural Resources Rehabilitation of Western Regional Sewers, Project 3-64 1-3 1.0-Introduction In addition, the EIR addresses the cumulative impacts of the proposed Project in connection with other past, present, and reasonably foreseeable projects. The EIR also addresses Significant and Unavoidable Environmental Impacts,Growth Inducement, and Energy Concerns. 1.2.4 Significance Determination This Draft EIR addresses the potential significant environmental effects of the proposed Project. Criteria indicating what constitutes a significant impact have been developed for each environmental resource analyzed in this Draft EIR and are defined in each impact analysis section. Impacts are categorized as follows. • Significant and unavoidable: All feasible mitigation is recommended, but impacts will remain significant following mitigation. • Less than significant with mitigation: Impact will be potentially significant but mitigated to a less than significant level. • Less than significant: Mitigation is not required under CEQA but may be recommended. • No impact. If an agency approves a project with significant environmental impacts that cannot be mitigated, the agency must adopt a statement that it is approving the project based on its overriding benefits despite its significant environmental effects (CEQA Guidelines § 15043.) This statement of overriding considerations must be included in the record of the proposed project approval(CEQA Guidelines§ 15093(a)). 1.2.5 Public Hearing On October 17, 2016,the Draft EIR was circulated to local, state, and federal agencies and to interested organizations and individuals who wished to review and comment on the document.

Rehabilitation of Western Regional Sewers, Project 3-64 1-7 1.0-Introduction This page intentionally left blank Rehabilitation of Western Regional Sewers, Project 3-64 1-8 2.0-Project Description 2.0 Project Description 2.1 Lead Agency The Orange County Sanitation District (OCSD) is the CEQA Lead Agency for the Rehabilitation of the Western Regional Sewers, Project No. 3-64 (proposed Project). Created in 1954, OCSD is the third- largest wastewater agency west of the Mississippi River and serves a population of more than 2.5 million people. OCSD is responsible for the collection,treatment, recycling, and disposal of treated wastewater generated within a 479-square-mile service area located in central and northwestern Orange County, California. OCSD's service area includes 20 cities, 4 special districts, and the County of Orange. OCSD is governed by a 25-member board of directors consisting of elected officials from each city and sewer agency located in OCSD's service area. OCSD facilities include over 396 miles of sewer lines, 15 off-site pumping stations, and 2 treatment plants. Currently,OCSD treats approximately 185 million gallons per day (mgd) of wastewater through two connected treatment plants located adjacent to the Santa Ana River, Reclamation Plant No. 1 in Fountain Valley and Treatment Plant No. 2 (Plant No. 2) in Huntington Beach. 2.2 Project Location OCSD is proposing to rehabilitate and/or replace the entire length of the Orange Western Sub-trunk,the Los Alamitos Sub-trunk, the Westside Relief Interceptor, and the Seal Beach Blvd. Interceptor. These sewer lines are located in the westernmost portion of the OCSD service area and are referred to collectively throughout this document as the Western Regional Sewers. Collectively, the Los Alamitos Sub-trunk, the Westside Relief Interceptor, and the Seal Beach Blvd. Interceptor convey sewage flows from the City of Seal Beach, the community of Rossmoor in unincorporated Orange County, the City of Los Alamitos, the City of Cypress, the City of La Palma, and other areas in the vicinity to the Westside Pump Station.The Orange-Western Sub-trunk conveys flows from the Cities of Cypress, Buena Park, and Anaheim to the Miller Holder Trunk and the Knott Interceptor. The Orange-Western Sub-trunk is not tributary to the Westside Pump Station.Sewage flow from all Project components ultimately is directed to OCSD Treatment Plant No. 2 located at 22212 Brookhurst Street in Huntington Beach. 2.2.1 Los Alamitos Sub-trunk The Los Alamitos Sub-trunk(Figure 2.2-1),constructed in 1959, is 34,620 feet long and has 90 manholes. The pipe diameter ranges in size from 18 to 30 inches.The Los Alamitos Sub-trunk is within the following cities: La Palma (La Palma Avenue and Denni Street), Cypress (Denni Street, Guardian Drive, Orange Avenue, Bloomfield Avenue, and Bloomfield Street), Los Alamitos (Bloomfield Street, West Cerritos Avenue, Chestnut Street,Sausalito Street,Oak Street, Katella Avenue, and Los Alamitos Boulevard), Seal Beach (Seal Beach Boulevard and Old Ranch Parkway), and the community of Rossmoor in unincorporated Orange County. Rehabilitation of Western Regional Sewers, Project 3-64 2-1 2.0-Project Description 2.2.2 Westside ReliefIntercentor The Westside Relief Interceptor (Figure 2.2-1) was constructed under two contracts in 1975 and 1976. This line is approximately 32,100 feet long with 81 manholes. Pipe size ranges from 15 to 39 inches in diameter. The Westside Relief Interceptor is within the following cities: La Palma (Crescent Avenue and Moody Street), Cypress (Moody Street, Orange Avenue, and Denni Street), Los Alamitos (Denni Street, Katella Avenue, and Los Alamitos Boulevard), and Seal Beach (Seal Beach Boulevard and Old Ranch Parkway). The Los Alamitos Sub-trunk and Westside Relief Interceptor meet at the intersection of Orange Avenue and Denni Street at Diversion Structure No. 65. Currently the Diversion Structure is configured to divert southerly flow from the Los Alamitos Sub-trunk to the west, rather than allowing it to continue southward along with flow from the Westside Relief Interceptor.The Los Alamitos Sub-trunk can flow into the Westside Relief Interceptor but not the other way around. The two lines subsequently run in a southerly direction along Los Alamitos Boulevard for approximately 10,800 feet. 2.2.3 Westside Pump Station and Force Main The Westside Pump Station is located at 3112 Yellowtail Drive in the community of Rossmoor in unincorporated Orange County.The pump station underwent a major renovation in 2008 (Project 3-52). This project consisted of rehabilitating the existing pump station to meet then-current OCSD standards and national and state codes. In addition, the station's capacity was increased to meet then-projected peak wet-weather flows. The work included modification of the ventilation systems, control systems, and the station's structure and isolation of the pump and electrical rooms from one another. The mechanical equipment, which then was located above ground, also was moved 30 feet below ground. The building underwent some minor modifications, and the roof was upgraded. The front gate was moved to the east of the property to ease access into the pump station. Additional landscaping was installed to enhance the front of the facility. 2.2.4 Orange-Western Sub-trunk The Orange-Western Sub-trunk (Figure 2.2-1), constructed in 1959, is 13,940 feet long and has 38 manholes. The pipe is 21 inches in diameter. The Orange-Western Sub-trunk consists of two segments. The first segment begins just north of the intersection of Crescent Avenue and Western Avenue in the City of Buena Park. The pipeline continues south on Western Avenue and turns west on West Orange Avenue before connecting to the Knott Interceptor. The second segment continues west on West Orange Avenue from the Knott Avenue intersection to the Miller Holder Trunk Sewer at the Valley View Street intersection. 2.2.5 Seal Beach Blvd. Interceptor The Seal Beach Blvd. Interceptor (Figure 2.2-1), constructed in 1970, is 5,530 feet long and has 8 manholes.The pipe is 51 inches in diameter.The Seal Beach Blvd. Interceptor begins just south of the Westside Pump Station at the end of Old Ranch Parkway in the City of Seal Beach. The pipeline continues south across the Interstate 405 (1-405) freeway right-of-way and in North Gate Road south of 1-405 until merging with Seal Beach Boulevard. The pipeline then continues south along Seal Beach Rehabilitation of Western Regional Sewers, Project 3-64 2-2 2.0-Project Description Boulevard until it reaches the Seal Beach Pump Station located at the intersection of Seal Beach and Westminster boulevards.The Seal Beach Naval Weapons Station extends to the centerline of Seal Beach Boulevard. Approximately 3,500 feet of Seal Beach Blvd. Interceptor is on easement on United States Navyland.

Further,the Westside Pump Station wet well was renovated in 2008 to extend its serviceable life. The repairs to the wet well are nearing the end of their expected life,and the wet well needs to be replaced. The purpose of the proposed Project is to increase the life of the Western Regional Sewers within the western region of OCSD's service area by another 50 years and to ensure that the projected 2040 wet weather peak flows(10-Year Storm)would be adequately contained. Objectives for the proposed Project include the following: • Extend the service life of the Western Regional Sewers by either rehabilitation of the existing lines or replacement of the lines on new alignment within the same streets • Replace the Westside Pump Station wet well to prevent potential for future failure and release of sewage to the environment • Accommodate projected 2040 wet weather peak flows(10-Year Storm) • Minimize impacts to the environment • Minimize existing surcharging in new/rehabilitated pipes • Minimize groundwater intrusion in new/rehabilitated pipes • Reduce potential for odors Without rehabilitation of the Western Regional Sewers and implementation of the Westside Pump Station improvements,the potential for groundwater intrusion and surcharging would continue and the wet well would further degrade. Additionally, OCSD would not meet requirements to accommodate projected 2040 wet weather flows, potentially resulting in unplanned sanitary sewer releases to the environment. 2.4 Project Description The proposed Project comprises the following main elements: (1) rehabilitation of portions of the Western Regional Sewers pipelines and manholes, (2) replacement of portions of the Western Regional Sewers pipelines and manholes, and (3) improvements to the Westside Pump Station. Pipeline rehabilitation would consist of lining the existing pipe or manhole. Pipeline replacement would consist of installing new, larger diameter pipelines within the Project area. Pump station improvements would Rehabilitation of Western Regional Sewers, Project 3-64 2-5 2.0-Project Description consist of replacement of the wet well and rehabilitation or replacement of the force main, as well as installation of an air scrubber or air jumper line for odor control and a new vent stack which would not exceed 20 feet in height.Additional details are provided below, based on location. As described in Section 2.5, OCSD is committed to minimizing impacts to the community and environment and may use trenchless construction methods where feasible; however, for the purposes of evaluating a reasonable worst case scenario for potential pipeline replacement impacts in this Draft Environmental Impact Report (EIR), trenchless construction methods are only assumed at all Orange County Flood Control District(OCFCD)facilities or other drainage channels and near Willow Street/Denni Street through to Denni Street(i.e., between the residences and beneath the Pacific Electric right-of-way and Der m Street Park). CEQA requires that an EIR describe a range of reasonable alternatives to the project, or to the location of the project,which would feasibly attain most of the basic objectives of the project but would avoid or substantially lessen any of the significant effects of the project, and evaluate the comparative merits of the alternatives (CEQA Guidelines Section 15126.6). Build alternatives associated with the construction of new pipelines and associated facilities lying outside existing street rights-of-way and easements would result in increased environmental impacts due to (1) constraints imposed by the need to serve existing local sewer connections, (2) substantial increases in excavation required to accommodate new pipelines and new routes,and (3)the potential need for construction of additional pump stations. Based on the purpose and objectives specified for the proposed Project in Section 2.3, therefore, only build alternatives utilizing existing public rights-of-way and OCSD easements have been considered within this Draft EIR. OCSD has thus identified the following two build alternatives as reasonable and feasible approaches to the proposed Project that would attain the Project's stated objectives: • Build Alternative 1 would replace portions of the existing Los Alamitos Sub-trunk and the Westside Relief Interceptor with new, larger capacity pipe. This Build Alternative also would rehabilitate portions of the existing Los Alamitos Sub-trunk (Approximately 15,540 linear feet) and the Westside Relief Interceptor (approximately 16,090 linear feet) sewer pipe in place. In addition, Build Alternative 1 would rehabilitate the Orange-Western Sub-trunk and the Seal Beach Blvd. Interceptor pipelines in place. Further, Build Alternative 1 would rehabilitate the Westside Pump Station force main and wet well. • Build Alternative 2 would replace the entire Los Alamitos Sub-trunk pipeline with new, larger capacity pipe. This build alternative also would divert all flow from the Westside Relief Interceptor north of Orange Avenue to the enlarged Los Alamitos Sub-trunk via a new diversion structure. In addition, Build Alternative 2 would rehabilitate the entire length of the Westside Relief Interceptor(approximately 32,100 feet), as well as the Orange-Western Sub-trunk and the Rehabilitation of Western Regional Sewers, Project 3-64 2-6 2.0-Project Description Seal Beach Blvd. Interceptor pipelines in place. Further, Build Alternative 2 would rehabilitate the Westside Pump Station force main and wet well. While these two build alternatives take different approaches to meeting the proposed Project objectives, they also have certain elements in common. The following subsections describe the two project build alternatives identified by OCSD for evaluation within this EIR in more detail, including discussion of those elements unique to and/or common between these alternatives. 2.4.1 Common Features of the Build Alternatives 2.4.1.1 Pipeline Rehabilitation Both build alternatives would rehabilitate the Orange-Western Sub-trunk and the Seal Beach Blvd. Interceptor pipelines using trenchless cured-in-place pipe (CIPP) methods (see Section 2.5.3). Further, approximately 16,090 linear feet of the existing Westside Relief Interceptor sewer pipe, ranging in size from 15 to 39 inches in diameter and running generally southward from the intersection of Moody Street and Crescent Avenue in the City of La Palma to the Westside Pump Station in the unincorporated area of Rossmoor, would be rehabilitated in place using trenchless CIPP methods under both build alternatives. Manholes associated with these pipelines would be replaced or rehabilitated as appropriate. As a result, environmental impacts associated with the construction of these common Project elements would be identical for both build alternatives. 2.4.1.2 Manhole Rehabilitation or Replacement All of the Western Regional Sewer pipelines would require either manhole rehabilitation or replacement under either build alternative. Manhole replacement involves removing and replacing the entire manhole structure. New manholes would have a built-in liner from the factory or a new liner system would be installed after the replacement manhole is installed. Manhole rehabilitation, on the other hand, would include concrete rehabilitation, relining, and resealing the existing manhole in place. This type of work requires a construction area approximately 15 feet wide and 30 feet long that extends around the manhole in order to accommodate construction equipment. Temporary lane closure would be required; and traffic would be directed around the construction area by signs,cones,and/or flagmen. 2.4.1.3 Westside Pump Station Both Build Alternatives 1 and 2 would entail rehabilitation or replacement of the Westside Pump Station force main and replacement of the wet well, as well as installation of an air scrubber or air jumper line for odor control. (The estimated work effort and associated equipment for this rehabilitation is presented in Table 2.4-1.) Construction activities at the Westside Pump Station would include complete replacement of the wet well. This would entail deep excavation (from 25 to 30 feet below ground surface (bgs]), non-vibratory driving, and shoring, either through the use of secant wall or slurry diaphragm wall methods (Figure 2.4-1 and Figure 2.4-2:Westside Pump Station Shoring—Typical Vibratory Pile Driving Method Rehabilitation of Western Regional Sewers, Project 3-64 2-7 2.0-Project Description as well as bypassing all flow entering the pump station during portions of construction. Should groundwater be encountered during excavation, sheet piling and dewatering pumps would be utilized. In the event that groundwater is encountered during excavation and dewatering occurs, the extracted water would be discharged to the sanitary sewer, which is part of the OCSD collection system. Where water exceeds OCSD thresholds for discharge to sewers, the contractor would either treat the water to meet OCSD sewer discharge requirements prior to discharge to sewers or containerize and dispose of dewatering at a licensed facility. In addition, the force main would be replaced or rehabilitated. New odor control facilities would be included.Odor control would be either an underground vent line (air jumper) between the wet well and the force main outlet or a new two-stage biological/chemical air scrubber.Should it be determined that the air scrubber unit would be necessary, OCSD would construct a new enclosure to house the air scrubber unit.The air jumper would be underground and result in minimal impacts. Construction of the air scrubber is considered a reasonable worst-case scenario for analysis within this graft EIR.Therefore, the impact analyses presented in Chapters 3 and 4 of this document are based on construction of an air scrubber unit at the Westside Pump Station. The decision regarding which method would be employed would be made prior to final design.

The course of this replacement would run along existing rights-of-way and easements generally southward from the intersection of Denni Street and the juncture of Del Amo Boulevard/La Palma Avenue in the City of La Palma to the intersection of Bloomfield Street and Cerritos Avenue in the City of Los Alamitos (Figure 2.4-3). The remaining 19,080 linear feet of Los Alamitos Sub-trunk pipe, running generally southward from this intersection to the Seal Beach Pump Station,would be rehabilitated in place using trenchless CIPP methods. • Approximately 16,090 linear feet of existing Westside Relief Interceptor sewer pipe, ranging in size from 15 to 39 inches in diameter and running generally southward from the intersection of Moody Street and Crescent Avenue in the City of La Palma to Myra Avenue in the City of Cypress (Figure 2.4-3), would be rehabilitated in place using trenchless CIPP methods. The remaining 16,010 linear feet of Westside Relief Interceptor, consisting of 27- to 36-inch pipe, running generally southward from Myra Avenue to the Westside Pump Station, would be replaced with larger capacity pipe.This replacement,via open-cut trenching,would occur along existing rights- of-way/easements. Subsequent to construction of the new pipes, the existing pipe and manholes would be abandoned in place and filled with concrete slurry. Construction of Build Alternative 1 components would be undertaken in phases to constrain construction-related NOx emissions below the South Coast Air Quality Management District (SCAQMD) exceedance threshold level of 100 lbs. per day(see Sections 3.2.4 and 3.2.5). The estimated cost of implementing Build Alternative 1 is from$100 to$135 million.

Under Build Alternative 2,the entire length of the Los Alamitos Sub-trunk pipeline(34,620 feet)would be replaced with increased diameter pipe to accommodate flows conveyed from the Westside Relief Interceptor through the new diversion structure located at the intersection of Denni Street and Orange Avenue.Currently,the diameter of the Los Alamitos Sub-trunk ranges from 18 inches to 30 inches. Under Alternative 2,it would be upsized to a range of 21 to 33 inches. The newly resized pipeline would require open-cut construction to a depth of approximately 31.3 feet bgs along the entire Los Alamitos Sub-trunk street alignment. As with Build Alternative 1,subsequent to construction of the new pipes,the existing pipe and manholes would be abandoned in place and filled with concrete slurry. As with Build Alternative 1, construction of Build Alternative 2 components would be undertaken in phases to constrain construction-related NOx emissions below the SCAQMD exceedance threshold level of 100 pounds(lbs.) per day(see Sections 3.2.4 and 3.2.5). The pipeline replacement work effort associated with Build Alternative 2 would result in the need to trench/excavate approximately 3,070 linear feet more than that required for Build Alternative 1 (the Los Alamitos Sub-trunk and the Westside Relief Interceptor combined), with a concomitant increase in potential construction-related impacts. Cost estimates for completing Build Alternative 2 range from $118 to$140 million.

Proled VIeINIy i M uoei vWill nmve 1 0.6 0 t nm e: Lr Rehabilitation of Western Regional Sewers, Project 3-64 2-13 2.0-Project Description 2.5 Construction The proposed Project is based on preliminary planning data. OCSD has retained an engineering consultant to verify preliminary data. The impact analysis in Chapter 3.0 of the Draft EIR assumes open- cut trench construction for all pipe replacement areas (see Figure 2.4-3), except where otherwise noted, such as at all OCFCD facilities or other drainage channels,from near Willow Street/Denni Street through to Denni Street (i.e., between the residences and beneath the Pacific Electric right-of-way and Denni Street Park). These sections would use trenchless construction methods to replace the pipe. CIPP methods would be utilized for all rehabilitation areas(see Figure 2.4-3, Figure 2.4-4,and Section 2.5.3). It should be noted that OCSD is committed to minimizing impacts to the community and the environment through the use of trenchless construction methods where feasible. Trenchless technologies tend to have fewer impacts than open-cut trenching. For example,trenchless construction techniques generally entail construction periods of shorter duration, require fewer pieces of construction equipment, and involve smaller construction areas when compared to open-cut trenching construction methods. For the purposes of disclosure, various trenchless construction methods/approaches are discussed in the following subsections; however, unless otherwise specifically noted (see above), potential impacts associated with open-cut trenching methods for pipeline replacement are evaluated within Chapter 3.0 of this EIR document, thus representing a reasonable worst-case scenario. Other construction components for the replacement pipes would include the reconnection of local sewers and the abandonment of old lines. Subsequent to the installation of the new pipe or the rehabilitation of existing pipe, local and permitted connections to the mainline would be rejoined. In locations where non-permitted connections occur or in locations where private laterals are connected directly to OCSD sewer lines, a new local connection/system would be constructed and connected in accordance with OCSD policy (Sewer Use Ordinance; Article 3, Section 3.7), which requires private laterals/connections to be connected to a city- or county-owned manhole or pipeline prior to being connected to an OCSD manhole or pipeline. Subsequent to construction of the new pipe, the existing pipe and manholes would be abandoned in place and filled with concrete slurry. 2.5a Open-Cut Trenchine Only portions of the Los Alamitos Sub-trunk and the Westside Relief Interceptor would require pipeline replacement. At this time, it is anticipated that the Los Alamitos Sub-trunk and the Westside Relief Interceptor contain approximately 15,540 feet and 16,010 feet of capacity-deficient pipe, respectively. The diameters for proposed up-sized pipes for the Los Alamitos Sub-trunk range from 18 to 30 inches for Build Alternative 1 and from 21 to 33 inches for Build Alternative 2.The proposed up-sized pipes for the Westside Relief Interceptor would be 30 to 39 inches in diameter. The replacement of these pipelines would require an open-cut trench up to approximately 7 feet wide.The new pipes would be installed on a parallel alignment at the same depth as the existing pipe. The replacement portions of the Los Alamitos Sub-trunk and the Westside Relief Interceptor would require excavation to depths up to Rehabilitation of Western Regional Sewers, Project 3-64 2-14 2.0-Project Description 22.7 feet bgs and 31.3 feet bgs for Build Alternative 1 and Build Alternative 2, respectively. Trenches likely would be braced using trench box or speed shoring(Figure 2.5-2). In the event that groundwater is encountered during excavation, dewatering would occur; and the extracted water would be discharged to the sanitary sewer, which is part of the OCSD collection system. Where water exceeds OCSD thresholds for discharge to sewers, the contractor would either treat to meet OCSD sewer discharge requirements prior to discharge to sewers, or the dewatering would be containerized and disposed at a licensed facility. Figure 2.5-1:Typical Open Trench Construction Scenario [:0! t � ' o � myw.wo Rro.,a"n e.�xnw�p .mm, .mm�Su Lo+eNre-m rms wmnmp v.wm.m LmIMp lmp Trenab g,ynmp The construction areas would need to be large enough to allow access for large construction equipment (e.g.,dump trucks,excavators, loaders,delivery trucks, etc.). Depending on traffic and other constraints, construction areas would be approximately 25 feet wide. It is anticipated that a minimum of 50 to 100 feet of excavation, installation, and backfilling would occur each day using open-cut trenching. The construction equipment and materials would be staged in parking lots,vacant lots,or segments of street lanes that are temporarily closed. The active construction area could extend along the alignment from between 500 to 1,000 feet for each of the project segments.The staging areas would be necessary along the construction routes. These staging areas would be selected to minimize hauling, traffic, and community disruption. Excavated material would be reused to backfill the open trench. Otherwise,a low strength "grout' material or imported backfill would be delivered to stockpiles near the open trench to be used as backfill. Once the new pipeline is in place, backfill would be placed in the trench.The streets would be compacted and paved in accordance with state and local building codes and encroachment permits (see Figure 2.5-1).The excavation spoils and all solid waste produced during open-cut trenching would be disposed at a properly permitted facility in accordance with federal and state laws. Rehabilitation of Western Regional Sewers, Project 3-64 2-15 2.0-Project Description Figure 2.5-2:Typical Open-Cut Trench Shoring ■ ram' � ��l;�r '� a► i,4 v, ry i Sewage bypass would be required as part of the construction efforts prior to connecting the new pipe into the existing system. Sewage bypass requires pumps and hoses to collect sewage upstream of the construction area and transport it to downstream of the construction area. Local, business, and emergency access would be provided at all times and would be a major component of the traffic control plans submitted to each affected jurisdiction for approval to obtain the encroachment permits and utility agreements needed in order to implement the proposed Project. Where feasible, the replacement pipeline alignment would be within center lanes/medians in order to minimize traffic disruption during construction. Preferred locations may require temporary closure of bike lanes, and the use of bus stops could be disrupted temporarily within the construction area. Additionally, on smaller streets or where other constraints occur, one-way traffic control and/or on- street parking restrictions may be required within the construction area.Additionally,construction on all major streets would occur during hours approved by the corresponding jurisdiction. It is anticipated that nighttime work may be required at certain times or in certain locations to reduce either traffic or other Rehabilitation of Western Regional Sewers, Project 3-64 2-16 2.0-Project Description impacts; however, all nighttime work would require prior approval by the affected corresponding jurisdiction. 2.5.2 Trenchless Rehabilitation Construction Methods As previously discussed, OCSD is committed to utilizing trenchless construction methods where feasible to minimize community and environmental impacts. Trenchless construction, however, may not be feasible due to soil or groundwater conditions or other site-specific conditions such as the location of adjacent utilities. Trenchless methods typically are used to construct under a busy roadway or a stream or to avoid other sensitive environmental areas. During the final design of the proposed Project,various locations would be considered for trenchless construction. In order to analyze a reasonable worst-case scenario, however, open-cut trenching methods for pipeline replacement are assumed for the impact determinations in Chapter 3.0, unless noted otherwise. A brief discussion of some of the other trenchless technologies that could be utilized for the pipe replacement portions of the proposed Project is provided below. Other trenchless rehabilitation technologies/methods are available and will be evaluated for use on the project for rehabilitation of the pipeline when additional capacity is not required. These methods include slip-lining; high-density polyethylene (HDPE) pipe liner; polyvinyl chloride (PVC) pipe liner; HDPE spirally wound profile wall liner; centrifugally cast,fiberglass reinforced, polymer mortar (CCFRPM) liner; and spray applied liquid and cementitious liners and other similar methods.Slip-lining involves inserting a new,smaller diameter pipe inside the existing pipe and grouting the annular space. The liner methods involve lining the pipe with various flexible materials that form up against the inside face of the existing pipe. Liquid and cementitious liners are sprayed onto the inside surfaces of the existing pipe with custom made remotely operated vehicles. CIPP was evaluated in this EIR as representative of trenchless rehabilitation methods which could be used that would meet Project objectives (see Section 2.5.3). 2.5.2.1 Pipe Bursting Pipe bursting or in-line expansion is a trenchless method by which the existing pipe is forced outward and opened by a bursting device (Figure 2.5-3). The bursting device, which has an expansion head that pushes the existing pipe radially outward until the pipe breaks, is pulled through the existing pipe by a cable rod and winch. As the bursting device breaks up the existing pipe, the new, typically larger pipe is pulled behind the bursting device and replaces the existing pipe. Rehabilitation of Western Regional Sewers, Project 3-64 2-17 2.0-Project Description Figure 2.5-3:Typical Pipe Bursting Method 2.5.2.2 Tunneling Tunneling requires a specialized tunnel-boring machine, as well as access and retrieval shafts that have shoring, such as sheet or concrete piles. Tunneling operations typically run continuously. The tunnel- boring machine drills the tunnel as it moves toward the retrieval shaft. The spoils are removed from behind the boring machine through the access shaft. Microtunneling can be used to install large- diameter pipe. Microtunneling features a smaller boring machine that is controlled remotely from the surface. The pipe is installed immediately behind the boring machine. When using the microtunneling method, generally, no workers are in the tunnel. Microtunneling can be used below the water table in certain soil types. 25.2.3 Horizontal Directional Drilling Horizontal directional drilling (HDD) uses a drilling rig on the surface to install a drill pipe in a shallow underground arc (Figure 2.5-4). The drilling rig bores a pilot hole that is filled with fluid. A swiveling reamer is then used to enlarge the hole to the size of the sewer pipe, and the sewer pipe is pulled through. Directional drilling often requires a large staging area to line up the pipe. The jack-and-bore method involves the use of a horizontal boring machine or auger to drill a hole and a hydraulic jack to push a casing through the hole. As the boring proceeds, a steel casing pipe is jacked into the hole; the pipeline is then installed in the casing.The casing isjacked using a large hydraulicjack in a pit located at one end of the crossing. The jacking pit would be several feet deeper than the replacement pipe elevation and up to 20 feet wide; ultimate depth and width of the temporary pits are dependent upon the replacement pipe depth and size. In pits below the water table, the use of sheet-piling, special bulkheads, and dewatering pumps and wellfields would be required. In the event that groundwater is encountered during excavation, dewatering would occur. The extracted water would be discharged to Rehabilitation of Western Regional Sewers, Project 3-64 2-18 2.0-Project Description the sanitary sewer, which is part of the OCSD collection system. Where water exceeds OCSD thresholds for discharge to sewers, the contractor would either treat to meet OCSD sewer discharge requirements prior to discharge to sewers or the dewatering would be containerized and disposed at a licensed facility. Figure 2.5-4:Typical Horizontal Directional Drilling Method 2.5.2.4 Cured-In-Place Pipe Rehabilitation Cured-in-place pipe (CIPP) is a rehabilitation method that utilizes the existing pipe as a host for a new liner. CIPP generally would be completed through the manholes and involves directing a resin-soaked liner through the existing pipe by pushing it ahead with either air or water or pulling it through with a constant tension winch (Figure 2.5-5). Prior to inserting the liner, the pipe would be prepped (e.g., bypassed, cleaned, smoothed, and surveyed). Once the liner has been inserted, the resin is then cured by either ultraviolet (UV) light, steam, or hot water. Subsequent to curing the pipe, any sewer laterals would be reconnected. The maximum construction area for the installation of CIPP using steam or water to cure would be 15 feet wide and 90 feet long (45 feet on each side of the upstream manhole) and 15 feet wide and 40 feet long at the downstream manhole. Curing using UV light would require a somewhat smaller area due to the use of different equipment (i.e., no boiler or refrigeration truck is required). For the purposes of this 8raft EIR, CIPP using water or steam is assumed because this curing method requires the most equipment, largest construction area,and longest curing times and is therefore a reasonable worst-case pipe rehabilitation scenario. Curing times between water and steam and UV light are highly dependent on site-specific subsurface conditions. Where applicable, curing time using UV light would be much shorter. Rehabilitation of Western Regional Sewers, Project 3-64 2-19 2.0-Project Description Installing a lining requires less disturbance and restoration than replacing the pipe. In some instances, however, sewer lining cannot be installed through existing manholes, and installation would require excavation for insertion pits to install the lining. If excavation pits are required, slip lining or other trenchless technologies also may be considered for pipe rehabilitation.Temporary lane closure would be required; however, any such lane closures would require prior approval by the affected corresponding jurisdiction. Under such circumstances,traffic would be directed around the construction area by signs, cones, and/or flagmen. Manhole rehabilitation/replacement would result in some traffic disruption and driver inconveniences; however, no closures of major arterials would take place. On narrower residential streets, parking restrictions and one-way traffic control may be required. Closures would be required only if necessary to ensure public safety,facilitate traffic flow around the construction area, or as otherwise required by the local jurisdiction. Figure 2.5-5:Typical Cured-in-Place Pipe Method i 2.5.3 Construction Schedule and Cost It is currently anticipated that construction would occur from March 2019 through March 2023. It is also anticipated that, with the exception of the work at the Westside Pump Station, project components as described above in Section 2.4 would be staged and constructed sequentially with potentially a slight overlap between the beginning of one project component and the completion of the prior project component.The construction activities at the Westside Pump Station are expected to have a duration of 18 months.The cost estimates for completing the proposed Project range from $100 to$135 million and $118 to $140 million for Build Alternatives 1 and 2, respectively. These build alternatives are discussed in Section 2.4. 2.6 Operations and Maintenance Future operations and maintenance would be very similar to the existing operations and maintenance. Ongoing activities related to the operation and maintenance of the Western Regional Sewer lines Rehabilitation of Western Regional Sewers, Project 3-64 2-20 2.0-Project Description include completing routine maintenance, cleaning sewer lines and manholes; performing visual inspections utilizing closed-circuit television and camera inspection;and conducting flow-monitoring, as- needed repairs, and chemical dosing for odor and corrosion control. The frequency of maintenance activities is based on site-specific conditions to minimize the risk of blockages or equipment failure that could lead to a sanitary sewer overflow. Gravity sewers such as the Western Regional Sewer lines are cleaned using combination trucks for hydraulic wash of the pipe and the vacuum removal of debris. Operation and maintenance activities generally require confined-space entry and can be completed with minimal disruption to surrounding areas. Corrective maintenance activities include repair or replacement of failed pumps, pipe segments, and manholes; replacement of manhole covers; root cutting; and root foaming with herbicide. Additionally, chemicals,such as magnesium hydroxide (MgOH), hydrogen peroxide(H202),sodium hydroxide (NaOH), and ferrous chloride(FeCl,), might be added directly to the trunk sewers, as needed,to control odor and corrosion. Maintenance activities such as those described above would occur in the build alternatives and the No Build Alternative. 2.7 No Build Alternative Under the No Build Alternative, no rehabilitation/replacement of the Western Regional Sewers or improvements to the Westside Pump Station would occur. Ongoing operations and maintenance activities, as described above in Section 2.6, would continue for the existing Western Regional Sewer lines. While the significant proposed Project-related construction impacts described in Chapter 3.0 would not occur, the No Build Alternative would not meet the proposed Project's purpose and objectives as identified in Section 2.3. The adverse conditions of groundwater intrusion and mineral deposition would continue,and the resulting impediment to wastewater flow would increase due to the existing sewer line capacity deficiencies and age. Under the No Build Alternative, portions of the Los Alamitos Sub-trunk and the Westside Relief Interceptor would remain capacity deficient and would be unable to accommodate the projected 2040 wet weather flows. The existing potential for surcharge conditions would remain,with an increasing potential for wastewater releases to the environment. The No Build Alternative would not reconstruct the Westside Pump Station wet well, further increasing the risk of failure and potential release of wastewater to the environment. The following table provides a summary of potentially significant impacts associated with each of the build alternatives analyzed in this EIR document.

Under this build alternative, those segments of the Los Alamitos Sub-trunk and the Westside Relief Interceptor that require replacement with larger diameter pipe, as denoted in Figure 2.4-3, would be constructed solely by using the pipe bursting method. The remaining portions of the Western Regional Sewer lines would be lined in place utilizing CIPP methods. The manholes that need to be replaced would be replaced utilizing the open-cut trench method, and less-intrusive rehabilitation methods would be used to rehabilitate the remaining manholes. The feasibility of using pipe bursting relies on site-specific soil and geotechnical information for all portions of the pipeline slated for replacement. A geotechnical investigation of the entire Project area would be conducted as part of detailed engineering design efforts. As noted in Section 2.5.2, trenchless Rehabilitation of Western Regional Sewers, Project 3-64 2-24 2.0-Project Description construction such as pipe-bursting may not be feasible due to soil or groundwater conditions or other site-specific conditions such as the location of adjacent utilities. Reliance on pipe-bursting construction methodology for the entire length of the proposed Project would be cost prohibitive. It also would require a longer construction schedule. These implications make this alternative infeasible. Furthermore, pipe bursting would be used only to replace pipes within an existing alignment. As such, the realignment of the Orange-Western Trunk and the Seal Beach Blvd. Interceptor are not included in this alternative.As a result,this alternative would not address deficiencies on those sewer lines, and the alternative would not meet the Project's objectives. Therefore, this alternative was eliminated from further consideration. 2.8.2 Westside Relief Interceptor and Los Alamitos Sub-trunk Only Alternative This alternative would utilize a combination of pipe bursting and open-cut trenching construction methods for both the Westside Relief Interceptor and the Los Alamitos Sub-trunk. No improvements to the Orange-Western Sub-trunk and the Seal Beach Blvd. Interceptor segments would be included in this alternative. The manholes in need of replacement would be replaced utilizing the open-cut trench method, and less-intrusive rehabilitation methods would be used to rehabilitate the remaining manholes.This alternative would not include any improvements to the Westside Pump Station. This build alternative was eliminated from further discussion/consideration because it would not address the Project objectives related to eliminating groundwater intrusion and mineral deposition within the Orange-Western Sub-trunk and the Seal Beach Blvd. Interceptor pipelines, nor would it address capacity deficient sewer lines or implement necessary improvements to the Westside Pump Station. 2.9 Environmentally Superior Alternative Based on the analysis in this 8caft EIR,the "environmentally superior alternative,"as that term is used in CEQA, is the No Build Alternative. If, as is the case with the proposed Project, the environmentally superior alternative is the No Build Alternative, CEQA Guidelines Section 15126.6(e)(2) requires the identification of an environmentally superior alternative among the other alternatives. As discussed above in Section 2.3, the purpose of the proposed Project is to extend the service life of the regional sewer system.Although both of the build alternatives would result in temporary significant construction impacts, both would meet all of the project objectives, including accommodating 2040 wet weather flows (10-Year Storm) and minimizing existing surcharging in new/rehabilitated pipes thus minimizing any potential for releases of wastewater to the environment. On the basis of the analyses presented in Chapter 3.0, of the two alternatives considered, Build Alternative 1 is considered to be environmentally superior to Build Alternative 2 due to its lower potential for construction-related impacts associated with air quality, noise, and traffic. As discussed in Section 3.2 Air Quality, construction emissions (criteria pollutants and greenhouse gases) under Build Rehabilitation of Western Regional Sewers, Project 3-64 2-25 2.0-Project Description Alternative 1(e.g., 15.47 lbs./day of PMso and 153.85 metric tons of greenhouse gases, or 153.16 metric tons CO2 equivalent amortized over a 30-year Project Life) are lower than those associated with Build Alternative 2 (19.92 lbs./day of PMso and 193.91 metric tons of greenhouse gases, or 191.89 metric tons COt equivalent amortized over a 30-year Project Life) because the increased emissions from the complete excavation/replacement of the Los Alamitos Sub-trunk under Build Alternative 2 would exceed the level of reduced emissions from the complete CIPP construction of the Westside Relief Interceptor. In a similar fashion, construction-related noise (Section 3.9) and traffic (Section 3.12) impacts are greater under Build Alternative 2 because of the prolonged construction period (75 additional construction days) and additional open-cut trenching (3,070 feet) required compared with Build Alternative 1. 2.10 Environmental Control Measures OCSD has incorporated Environmental Control Measures (ECM) into the proposed Project, consistent with OCSD's contractual and general legal requirements. Construction would be performed by qualified contractors. The contract documents, plans, and specifications for the proposed Project would incorporate the requirements of these ECMs. These requirements are listed in Table 2.10-1 and are referenced throughout the impact discussions in Chapter 3.0, Environmental Analysis,of this PFA4 EIR. Table 2.10-1:Environmental Control Measures Environmental Resource Area Environmental Control Measure Air Quality OCSD will post signage throughout the construction areas that provides contact information and a phone number for people with questions or concerns regarding air quality. OCSD will ensure that the contractor complies with all South Coast Air Quality Management District(SCAQMD)Rules and Regulations described in Section 3.2.1.3. OCSD will require contractors to turn off fuel-or electricity-consuming construction equipment when not in use. Aesthetics The construction of a new enclosure at the Westside Pump Station,if an air scrubber is required,will be completed under a building permit from the County. The new enclosure will be painted to match the color of the existing building;the appearance of the new enclosure will be similar in color and height to the existing building on site.The new vent stack(if required)will be designed to look like a typical roof vent or a chimney and will not exceed the existing roof height. In the event that work is required outside the allowable construction hours, adjacent property owners will be notified in advance;and a variance will be obtained from Orange County,as applicable. s The 30-year amortization extends from the end of construction, including the four preceding years, so the beginning construction emissions span 34 years;year 1 spans 33 years,year 2 spans 32 years,year 3 spans 31 years,and year 4 spans 30 years.Please refer to the discussion in Section 3.6 Greenhouse Gases. Rehabilitation of Western Regional Sewers, Project 3-64 2-26 2.0-Project Description Table 2.30-1:Environmental Control Measures Environmental Resource Area Environmental Control Measure Biological Resources The crossings of all Orange County Flood Control Channels 0r other drainage channels will utilize trenchless technology to perform work beneath the channel. No impacts within the channels will result. Cultural Resources/Tribal Cultural If human remains are discovered during site preparation,grading,or excavation, Resources Health and Safety Code Section 7050.5 states that further disturbances and activities shall cease in any area or nearby area suspected to overlie remains,and that the County Coroner shall be contacted.Pursuant to California Public Resources Code Section 5097.98,if the remains are thought to be Native American,the Coroner will notify the Native American Heritage Commission, which will then notify the Most Likely Descendant(MUD).Further provisions of California Public Resources Code 5097.98 are to be followed as applicable. Geologic Resources OCSD has contracted for subsurface investigations,as part of engineering design efforts,to evaluate the soil and geologic conditions within the proposed Project area,address excavation and dewatering requirements,and develop detailed design criteria forthe pipelines and associated improvements.All applicable geotechnical recommendations will be adhered to during the construction of the proposed Project.The project will be designed and constructed in accordance with the current Uniform Building Code and California Building Code seismic engineering design standards. Subsurface exploration will include exploratory borings,well development, and/or other exploration techniques to adequately evaluate the soil,geologic, and groundwater conditions along the alignment and at the pump station site. Borings will be performed at intervals as determined to be appropriate bythe geotechnical consultant. Excavations that appear unstable to the OCSD construction inspector or are deeper than 4 feet will be shored.Friable sand zones which are subject to caving may be determined by the construction inspector to warrant continuous shoring. For planning purposes,it is recommended that the on-site sail be considered as Type C soil in accordance with the Occupational Safety and Health Administration (OSHA)soil classification.Type C soils include granular soils such as gravel,sand, and loamy sand,which have a greater potential for cave-in. Hazards and Hazardous Materials OCSD will require all contractor(s)to handle,transport,and dispose of all excavated soil and/or groundwater removed from the construction area in accordance with state,federal,and local requirements associated with the use, handling,storage,transportation,and disposal of hazardous material.All groundwater removed during replacement and/or rehabilitation activities will be handled in accordance with the dewatering requirements described below in "General Construction Measures." Prior to construction,OCSD will require its construction contractor to develop a Materials Management Plan(MMP)to address the identification,handling,and management of potential contaminated soil and groundwater that may be encountered during construction.The MMP also will address health and safety procedures for workers and site visitors to include personal protective equipment Rehabilitation of Western Regional Sewers, Project 3-64 2-27 2.0-Project Description Table 2.10-1:Environmental Control Measures Environmental Resource Area Environmental Control Measure (PPE),applicable action level criteria,engineering controls,and administrative controls to limit potential exposure to site contaminants.Procedures outlined in the MMP will specify,a[a minimum,waste sampling methods,excavation and stockpile management,contaminated soil treatment/disposal options,and contaminated wastewater treatment/disposal options. Noise Prior to any nighttime construction,OCSD will verify that the construction contractor(s)have obtained all necessary approvals from the corresponding local junsdiction(s). OCSD will limit construction hours for the Westside Pump Station to 8:00 a.m.to 5:00 p.m.,Monday through Friday,to minimize noise impacts of construction activities on adjacent residences,unless otherwise required for completion of construction activity and or for system testing.In the event that work is required outside the allowable construction hours at the Westside Pump Station,adjacent property owners will be notified in advance;and a variance will be obtained from Orange County,as applicable. Recreation OCSD WIII prevent all contractor(s)from closing or otherwise preventing public use of parks adjacent to the Project area.OCSD WI I I ensure that public access to all parks adjacent to the Project area is maintained during construction. Traffic and Circulation OCSD will require its construction contractors to prepare and implement traffic control plans(TCPs)that specifically address construction traffic and road closures within the public rights-of-way of the Cities of Anaheim,Buena Park, Cypress,La Palma,Los Alamitos,and Seal Beach and within the County of Orange. The TCPs will specify permitted construction hours and will require that vehicular access be maintained in the Project area throughout construction of the proposed Project.The TCPs will also include provisions requiring emergency vehicle passage at all times and signage and Flagmen when necessary.Traffic control plans will be approved by each corresponding jurisdiction prior to the start of construction. The Orange County Fire Authority Emergency Communications Center will be notified of construction days and times,prior to any construction that may result in delay of emergency response services to the Public. In Preparing the TCP,the contractor would be required to consult with the affected school districts to ensure that specified construction times would have minimal impact on school access and activities.If deemed necessa ry during these consultations,construction times would be limited so that construction would not occur during school itroo-off and Pick-up times.The TCPs would also soecifv provisions to ensure pedestrian safety as well as school bus passaee at all times,including the use of signage and flagmen immediately before,within and immediately after the construction zone as necessary for Pedestrian safety and to allow school busses to pass. In addition,the TCPs will contractually prohibit concurrent construction of the Westside Relief Interceptor and the Los Alamitos Sub-trunk on Katella Avenue,in order to ensure that emergency vehicle passage would be maintained at all Rehabilitation of Western Regional Sewers, Project 3-64 2-28 2.0-Project Description Table 2.10-1:Environmental Control Measures Environmental Resource Area Environmental Control Measure times. General Construction Measures In compliance with the required Construction General Permit,OCSD will require construction contractors to prepare and implement stormwater pollution prevention plans(SWPPPs)that specify best management practices(BMPs)to be implemented during project construction to prevent pollutants from entering stormwater and to control erosion and sedimentation.The SW PPPs will be prepared and submitted to the Regional Water Quality Control Board(RWQCB) for review and approval prior to the start of construction.Construction BMPs may include the following: • Erosion Control Practices—including physical stabilization BM Ps(hydraulic mulch,soil binders,straw mulch,geotextiles,plastic covers,man), vegetation stabilization BM Ps(hydroseeding),and wind erosion control (application of water) • Sediment Control Practices—including perimeter protection(silt fence,fiber rolls,sand bag barrier,straw bale barrier),storm drain inlet protection, resource protection(gravel bag berm,silt fence,fiber rolls),sediment capture(sediment trap,desilting basin),velocity reduction(silt fence,check dam,velocity dissipation devices,sediment basin),and off-site sediment tracking(stabilized construction entrance/exit,construction road stabilization,entrance/outlet tire wash) • Waste Management and Materials Pollution Control Practices—including spill prevention and control,solid waste management,hazardous waste management,contaminated soil management,concrete waste management, sanitary/septic waste management,liquid waste management,vehicle and equipment cleaning,vehicle and equipment fueling,and vehicle and equipment maintenance • Materials Management Practices—including material delivery and storage, material use,and stockpile management • Non-stormwater Management Practices—including water conservation, dewatering operations,paving and grinding operations,temporary stream crossing,clear water diversion,illicit connection reporting,potable water/irrigation,vehicle and equipment cleaning,vehicle and equipment fueling,vehicle and equipment maintenance,pile-driving operations, concrete curing,concrete finishing,materials and equipment use over water, structure demolition,temporary batch plants,and stream bank stabilization Operational BMPs may include the following: Pollution Prevention • Inspect potential non-stormwater discharge flow paths and clear/cleanup any debris or pollutants found(i.e.,remove trash,leaves,sediment,and wipe up liquids,including oil spills). Sewer System Cleaning • Sewer lines will be cleaned on a regular basis to remove grease,grit,and Rehabilitation of Western Regional Sewers, Project 3-64 2-29 2.0-Project Description Table 2.10-1:Environmental Control Measures Environmental Resource Area Environmental Control Measure other debris that may lead to sewer backups. • Establish routine maintenance program.Cleaning will be conducted at an established minimum frequency and more frequently for problem areas that are identified. • Cleaning activities may require removal of tree roots and other identified obstructions. Preventive and Corrective Maintenance • During routine maintenance and inspection,note the condition of sanitary sewer structures and identify areas that need repair or maintenance. • Document suggestions and requests for repair and report the information to the appropriate manager or supervisor. • Prioritize repairs based on the nature and severity of the problem. Immediate clearing of blockage or repairs is required where an overflow is currently occurring or when urgent problems may cause an imminent overflow.These repairs may be temporary until scheduled or capital improvements can be completed. Response and Containment • Establish lead department/agency responsible for spill response and containment.Provide coordination within departments. • When a spill,leak,and/or overflow occurs,keep sewage from entering the storm drain system to the maximum extent practicable by covering or blocking storm drain inlets or by containing and diverting the sewage away from open channels and other storm drain facilities. • Remove the sewage using vacuum equipment or use other measures to divert it back to the sanitary sewer system. • Record required information at the spill site. • Perform field tests as necessary to determine the source of the spill. • Develop additiona l notification procedures regarding spill reporting as needed. If groundwater dewatering is necessary,construction site dewatering water will be tested.Where suitable,water will be discharged to the OCSD sewer.Where water exceeds OCSD thresholds for discharge to sewers,the contractor will either treat to meet OCSD sewer discharge requirements or containerize and dispose of dewatering at a licensed facility. 2.11 Project Approvals OCSD will use this BPaft EIR to consider implementation of the proposed Project. As CECIA Lead Agency, OCSD may use this EIR to select either Build Alternative 1 or Build Alternative 2; approve the proposed Project; make Findings regarding identified impacts; identify mitigation measures; and, if necessary, Rehabilitation of Western Regional Sewers, Project 3-64 2-30 2.0-Project Description adopt a Statement of Overriding Considerations regarding these impacts. Among others, the California Department of Transportation (Caltrans); County of Orange; and the Cities of La Palma, Cypress, Buena Park, Anaheim, Los Alamitos, and Seal Beach are responsible agencies that have discretionary approval over components of the proposed Project. The agencies and entities with discretionary approval over the proposed Project are listed in Table 2.11-1.

Additionally, it was determined that potential impacts to Hydrology and Water Quality and Utilities would be less than significant. These environmental resource areas receive no further analysis in this document. This chapter contains sections for each of the environmental resource areas that are analyzed in this Environmental Impact Report (EIR). Each section contains the following general subsection headings: • Regulatory Setting • Existing Conditions • Thresholds of Significance • Impact Analysis • Mitigation Measures • Significance after Mitigation The "Regulatory Setting" sections discuss federal, state, and local laws, ordinances, and regulations pertaining to the applicable environmental resource.The "Existing Conditions"sections provide relevant background information about the proposed Project's existing environmental setting. The "Significance Criteria" sections present the thresholds for determining whether the environmental effects of the proposed Project and its Alternatives are significant environmental impacts. The "Impact Analysis" sections present the potential environmental consequences of the construction and operation of the proposed Project and the proposed Project's Alternatives. The "Mitigation Measures" sections describe all feasible means to reduce the impact to a level less than significant. The "Significance After Mitigation" sections state the level of environmental impacts after the application of the identified mitigation measures. With regard to evaluating potential Project-related impacts,the two build alternatives evaluated within this EIR each have unique approaches to meet the Project objectives stated in Section 2.3. They also have certain elements in common. For example, as discussed in Section 2.4, both build alternatives would entail rehabilitation/replacement of the Westside Pump Station force main and wet well. In addition, both build alternatives would entail rehabilitation of the Orange-Western Sub-trunk and Seal Beach Blvd. Interceptor pipelines using trenchless methods. Further, under both build alternatives, approximately 3 miles of existing Westside Relief Interceptor sewer pipe would be rehabilitated in place using trenchless methods. Manholes associated with these pipelines would be replaced or rehabilitated as appropriate. Consequently, environmental impacts associated with the construction of these common Project elements would be identical for both build alternatives. Rehabilitation of Western Regional Sewers, Project 3-64 3-1 3.0-Environmental Analysis As a result,the impact analyses for each of the resource areas identified below are presented/discussed in the following format: • Common Build Alternative Element Impacts • Build Alternative 1—Specific Element Impacts • Build Alternative 2—Specific Element Impacts In this light, the environmental impacts associated with each build alternative are the sum of its common and specific element impacts. Consistent with California Environmental Quality Act(CEQA) Guidelines Section 15126.2(a),the baseline for the environmental setting used in this EIR is the existing physical conditions at the time the NOP was issued in November of 2015. The Chapter 3.0 subsections are listed below: • Section 3.1,Aesthetics • Section 3.2,Air Quality • Section 3.3, Biological Resources • Section 3.4,Cultural Resources • Section 3.5,Geology and Soils • Section 3.6,Greenhouse Gas Emissions • Section 3.7, Hazards and Hazardous Materials • Section 3.8, Land Use and Planning • Section 3.9, Noise • Section 3.10, Public Services • Section 3.11, Recreation • Section 3.12,Traffic and Circulation • Section 3.13,Tribal Cultural Resources Rehabilitation of Western Regional Sewers, Project 3-64 3-2 3.1-Aesthetics 3.1 Aesthetics This section addresses the aesthetic and visual quality impacts associated with the proposed Project and recommends mitigation measures where necessary to avoid or reduce significant impacts. This section includes a description of the existing visual conditions in the proposed Project area and an evaluation of the potential effects on those existing visual conditions. 3.1.1 Regulatory Setting 3.1.1.1 State California Scenic Highway Program The California Department of Transportation (Caltrans)administers the state Scenic Highway Program to preserve and protect State scenic highway corridors from modifications that would diminish the aesthetic value of those corridors. (California Streets and Highways Code,Section 260 et seq.).The State Scenic Highway Program includes a list of highways that are either eligible for designation as scenic highways or have been officially designated and are identified in the California Streets and Highways Code, Section 263. Under this Program, an official designation as a scenic highway requires a local jurisdiction to enact a scenic corridor protection program that protects and enhances scenic resources by regulating, among other things: land uses, the design of sites and structures, signage, landscaping, and grading. If a highway is listed as eligible for official designation, it is also part of the Scenic Highway Program and care must be taken to preserve its eligibility status.The Project area does not contain any roadways that are officially designated or eligible under the Scenic Highway Program (Caltrans 2015). 3.1.1.2 Local County of Orange General Plan The proposed improvements at the Westside Pump Station are located in the community of Rossmoor within unincorporated Orange County;thus the Orange County General Plan applies at this location.The County of Orange General Plan Transportation Element (County of Orange 2011, Chapter 4) includes a Scenic Highways Plan that attempts to incorporate safety, utility, economy, and aesthetics into the planning, design, and construction of scenic highways. The Transportation Element identifies viewscape corridors and routes that traverse a corridor within which unique or unusual scenic resources and aesthetic values are identified. This designation is intended to minimize the impact of development on the significant scenic resources along the route. County of Orange Municipal Code Section 4-6-7. of the Orange County Municipal Code limits construction activities to between the hours of 8:00 p.m. and 7:00 a.m. on weekdays and Saturday,and prohibits construction at any time on Sunday or a federal holiday. Rehabilitation of Western Regional Sewers, Project 3-64 3-3 3.1-Aesthetics City of Los Alamitos General Plan The City of Los Alamitos General Plan does not contain any guidance regarding visual or aesthetic resources relevant to the proposed Project.This is due to the lack of coastal elements, designated scenic highways,or areas within the City identified as important viewsheds. City of Los Alamitos Municipal Code The City of Los Alamitos Municipal Code identifies land use categories, development standards, and other general provisions that ensure consistency between the General Plan and proposed development projects within the City. The following provisions from the municipal code are intended to minimize adverse aesthetic impacts, including light and glare,and are relevant to the proposed Project.The City's Municipal Code (Section 17.24.20) specifically exempts construction-related noise sources that take place between the hours of 7:00 a.m. and 8:00 p.m. on weekdays and Saturday, and prohibits construction at any time on Sunday or a federal holiday. Standards of Design(Chapter 16.12) This section of the municipal code outlines requirements for the design of roadways, infrastructure, slopes, landscaping, and other elements of the built environment in Los Alamitos. Although the requirements largely focus on consistency with other local plans and state regulations, they address several aesthetic concerns. Provisions that directly relate to the visual environment of the City include the requirement that new developments place utility lines underground and provisions requiring adequate landscaping and screening. 17.14.040 Light and Glare "Shielding of Light Source:Where the light source is visible from outside the project boundary,shielding shall be required to reduce glare so that neither the light source nor its image from a reflective surface shall be directly visible from a point 5 feet or more beyond the property line.The requirement shall not apply to single-family residential uses,traffic safety lighting,or public street lighting. "Mechanical or Chemical Processes: Light, heat,or glare from mechanical or chemical processes, or from reflective materials used or stored on a site,shall be shielded or modified to prevent emission of light or glare beyond the property line. "Sky-Reflected Glare: Sky-reflected glare shall be controlled. Glare will not inconvenience or annoy persons or interfere with the use and enjoyment of nearby property"(Ord.688 4 1,2006). City of Seal Beach General Plan Because of its proximity to the Pacific Ocean, Seal Beach is subject to the state-mandated Local Coastal Program and is within the jurisdiction of the California Coastal Commission. The 1976 California Coastal Act, which provides protection for the natural and scenic resources of the coastal area, requires the preparation of a local coastal program for jurisdictions with land within the coastal zone. The policies Rehabilitation of Western Regional Sewers, Project 3-64 3-4 3.1-Aesthetics defined by the Local Coastal Program set the standards that preserve and conserve the communitys coastal resources. The City of Seal Beach Local Coastal Program policies are included by reference as part of the General Plan. The Seal Beach Blvd. Interceptor, which is the portion of the proposed Project within the City of Seal Beach, is not located within the California Coastal Commission's jurisdiction.The coastal zone boundary is located just south of Westminster Boulevard,which is south of and does not include the Project area. The City of Seal Beach Municipal Code The Citys Municipal Code (Section 17.15.025) notes that construction activities are prohibited between 8:00 p.m. and 7:00 a.m. on weekdays, 8:00 p.m. and 8:00 a.m. on Saturdays, and any time on Sundays and holidays. The following provision from the City of Seal Beach Municipal Code is intended to minimize adverse impacts from light and glare and is relevantto the proposed Project. 11.4.10.020 Performance standards "Lighting shall be provided subject to the following requirements. "Outdoor Illumination Levels. This requirement shall not apply to single-unit residential uses, traffic safety lighting, or public street lighting. A minimum of 0.5 foot-candle of illumination shall be maintained at the land surface throughout the area to be illuminated. In addition, related business use parking areas shall conform to the standards set forth in Table 11.4.10.020.A: Outdoor Parking Area Illumination Levels by Use(Average Foot-Candles)." City of Anaheim General Plan The City of Anaheim General Plan Community Design Element provides the following policy guidance relative to aesthetic resources and the proposed Project. The goals and policies that follow start at the "macro" level of the community and then proceed downward to specific districts.These policies apply to projects within the City, combined with the development standards of the Zoning Code and design guidelines for specific areas within the City. Construction limits are provided in the City of Anaheim Municipal Code (see below). Modification of construction hours may be granted by the Director of Public Works or Building Official. "Goal 1.1: Create an aesthetically pleasing and unified community appearance within the content of distinct districts and neighborhoods. "Policy 2: Identify and preserve/enhance view corridors for major landmarks, community facilities, and natural open space in the planning and design of all public and private projects. Rehabilitation of Western Regional Sewers, Project 3-64 3-5 3.1-Aesthetics "Policy 9: Minimize visual impacts of public and private facilities and support structures through sensitive site design and construction. This includes but is not limited to: appropriate placement of facilities; undergrounding, where possible; and aesthetic design (e.g.,cell tower stealthing)." The City of Anaheim Municipal Code Title 6, Chapter 6.70 of the City of Anaheim Municipal Code prohibits construction between the hours of 8:00 p.m. and 7:00 a.m. on weekdays and Saturdays, and any time on Sundays or federal holidays. The following provision from the City of Anaheim Municipal Code is intended to minimize adverse impacts from light and glare and is relevant to the proposed Project. Title 18(Zoning)18.08.1202 Commercial Zones. Operational Uses/18.10.030 Uses. Industrial Zones "All uses shall be conducted in a manner so as not to be objectionable by reason of noise, odor, dust, fumes,smoke,vibrations,excessive lighting(glare),or other similar causes" City of La Palma General Plan The City of La Palma General Plan does not contain any guidance regarding visual or aesthetic resources relevant to the proposed Project.This is due to the lack of coastal elements,designated scenic highways, or areas identified as important viewsheds. It does, however, limit construction hours to Monday through Friday from 7:00 a.m. to 5:00 p.m. and Saturday from 9:00 a.m.to 5:00 p.m. No construction is allowed on Sundays or holidays. Any construction outside these hours would be required to obtain a variance that would include considerations such as glare and visual impacts of a use. The City of Buena Park General Plan The City of Buena Park General Plan does not contain any guidance regarding visual or aesthetic resources relevant to the proposed Project.This is due to the lack of coastal elements, designated scenic highways, or areas within the City identified as important viewsheds. Construction is prohibited on Sundays and any other day between the hours of 8:00 p.m. and 7:00 a.m. Variances may be permitted by the city engineer. The City of Cypress General Plan The City of Cypress General Plan Circulation Element goals and policies define the City's vision for a balanced,efficient circulation system which incorporates many modes of travel and which allows for the safe movement of people and goods in and around Cypress.These goals recognize the constraints posed by the existing built environment but also capitalize upon the opportunities created by established transportation routes. Construction activities are prohibited between the hours of 8:00 p.m. and 7:00 a.m. on weekdays, 8:00 p.m. and 9:00 a.m. on Saturdays, and any time on Sundays and federal holidays. A variance would be required if construction activities occur outside the specified days and times. Rehabilitation of Western Regional Sewers, Project 3-64 3-6 3.1-Aesthetics "Goal 1: Maintain a safe, efficient, economical, and aesthetically pleasing transportation system providing for the movement of people, goods, and services to serve the existing and future needs of the City of Cypress. "Policy 1.6: Encourage the development of aesthetic streetscapes to promote a positive City image and provide visual relief." 3.1.2 Existing Conditions The following section describes several key terms used to examine the existing scenic resources of the region and the Project area. Visual Character The visual character of a site is defined by its physical characteristics, such as landform, vertical relief, type of vegetation, textures, and patterns; the presence of clear or cascading water; range of color in the soil, rock, vegetation, or water; variety in landscape; man-made structures visually different from the natural environment; and other visually distinguishing elements. Visual Quality The visual quality of a site is based on the interpretation of physical features from the viewer's perception. It is evaluated by identifying the vividness, intactness, and unity present in the viewshed. Vividness is the visual power or memorability of landscape components as they combine in distinctive visual patterns. Intactness is the visual integrity of the natural and man-made landscape and its freedom from encroaching elements. It can be present in well-kept urban and rural landscapes, as well as in natural settings. Unity is the visual coherence and compositional harmony of the landscape considered as a whole. Unity frequently results from the careful design of individual man-made components in the landscape. Views Views are composed of three distinct parts:the viewing scene itself;the viewing location from which the public sees the viewing scene; and the view corridor, which is the volume of space between the viewing scene and the viewing location. The area that can be seen from a given vantage point and viewing direction is also referred to as the viewshed. Viewer Sensitivity Viewer sensitivity is defined as both the viewers concern for scenic quality and the viewer's response to change in the visual resources that make up the view. This is typically measured by whether a scene is routine or unique to the viewer, and whether a view has a specific element that draws the viewer's focus. Rehabilitation of Western Regional Sewers, Project 3-64 3-7 3.1-Aesthetics Liaht and Glare Light and glare can affect the visual quality of a site, especially the availability and quality of nighttime views. Light is the level of brightness produced by artificial and natural sources. Glare is unwanted or nuisance light, including exceptionally bright light sources that are in sharp contrast to surrounding light levels and may cause annoyance,discomfort,or visual impairment. 3.1.2.1 Regional Setting The Project area is located in Orange County (County), which is a diverse geographic area including mountains, hills, flatlands, and coastal shoreline. The terrain ranges from sea level to over 5,000 feet above mean sea level in the Santa Ana Mountains. The County is highly urbanized and is generally built out in the central to northwest portion. The eastern and southern areas contain more natural and open space, including numerous regional and wilderness parks.The Cities of Anaheim, Buena Park,Cypress, La Palma, Los Alamitos, and Seal Beach are all located in a heavily developed area in the northwestern portion of Orange County. 3.1.2.2 Project Site The Project area is generally located within areas zoned as transportation and within public rights-of- way; however, it also contains areas zoned as residential, commercial, and open/space recreation (see Figures 3.8-1 through 3.8-7 in Section 3.8 Land Use and Planning). Overall, the visual character of the Project area can be described as a transportation corridor within a highly urbanized area. The Westside Relief Interceptor,the Los Alamitos Sub-trunk,the Orange-Western Sub-trunk, and the Seal Beach Blvd. Interceptor alignments extend through a network of roadways with public rights-of-way and landscape components including trees, shrubs,grass areas, sidewalks, and fences.The Seal Beach Blvd. Interceptor alignment along Seal Beach Boulevard is adjacent to the Naval Weapons Station Seal Beach, containing area used for agriculture along the east side of the roadway.The Los Alamitos Sub-trunk alignment also extends through the Forest Lawn Memorial Park cemetery,where views include a landscaped grass area with trees and shrubs as well as paved roads. The Project area within Forest Lawn (i.e., Guardian Drive) traverses the middle of Forest Lawn and would be visible from many areas within the property. The Westside Pump Station is located in a single-family residential neighborhood. The Westside Pump Station includes landscaping with trees and shrubs as well as a brick fence with a sliding metal access gate. No designated scenic areas or public viewpoints of importance are within the Project area. 3.1.3 Thresholds of Significance The following significance criteria are based on Appendix G of the California Environmental Quality Act (CEQA) Guidelines (14 California Code of Regulations 15000 et seq.) and are used to evaluate the potential for significant project impacts related to aesthetics. Project impacts on aesthetics will be significant if the proposed Project would: AES-1: Substantially degrade the existing visual character or quality of the site and its surroundings; or Rehabilitation of Western Regional Sewers, Project 3-64 3-8 3.1-Aesthetics AES-2: Create a new source of substantial light or glare which would adversely affect day or nighttime views in the area Other impact significance criteria for Aesthetics, identified in Appendix G of the CEQA Checklist, have been evaluated previously in Section 4.1 of the Initial Study for the proposed Project (See Appendix A). This previous evaluation determined that the proposed Project will result in either no impact or in less than significant impacts to Aesthetics under the following significance criteria: • Have a substantial adverse effect on a scenic vista • Substantially damage scenic resources, including, but not limited to, trees, rock outcroppings, and historic buildings within a state scenic highway As a result, impact significance criteria other than those specifically identified in this section have not been evaluated further within this Environmental Impact Report(EIR). 3.1.4 Impact Analysis Both of the build alternatives would require construction activities in all of the same locations. Both build alternatives would require the same activities in the most visually sensitive areas, which include the Forest Lawn Memorial Park cemetery,the vicinity of the Westside Pump Station improvements, and within the residential community of Rossmoor. There are no substantive differences between the two build alternatives' locations, and the aesthetic impacts of either of the build alternatives are anticipated to be the same for visual resources within the Project area. Thus, the impacts described in this section are the same for Build Alternative 1 and Build Alternative 2. AES-1: Would the Project substantially degrade the existing visual character or quality of the site and its surroundings? 3.1.4.1 Construction Impacts Rehabilitation or replacement of the Orange-Western Sub-trunk, the Los Alamitos Sub-trunk, the Westside Relief Interceptor, and the Seal Beach Blvd. Interceptor would occur primarily within developed areas within public rights-of-way or Orange County Sanitation District's (OCSD) easements and would be located below the ground surface.The proposed Project would result in temporary visual impacts due to the presence of heavy machinery and construction activities. The construction activities for the Western Regional Sewers Project would continuously move and would not remain in any one location for extended periods of time.The replacement activities would take the longest.As described in Section 2.5, the proposed Project would complete up to 100 feet of pipeline replacement per day. The business operations and the scenic areas within the Forest Lawn Memorial Park cemetery are more sensitive to the presence of construction equipment and materials than the typical businesses or the residential areas adjacent to city streets. The Project area within Forest Lawn would be visible from many areas of the Forest Lawn property. The replacement of the Los Alamitos Sub-trunk within the cemetery would be completed in approximately two to three months. Because of the temporary nature Rehabilitation of Western Regional Sewers, Project 3-64 3-9 3.1-Aesthetics of the proposed construction activities within Forest Lawn, visual impacts would not be significant. However, the visual impacts of the construction equipment and activities would degrade the existing tranquil character and quality of the site and the surroundings during interment ceremonies due to the hypersensitivity of the participants. This would be a temporary significant impact requiring implementation of mitigation measures AES MM 1, CUL MM 3, and CUL MM 5 to reduce the impact to less than significant. Additionally, replacement of the Los Alamitos Sub-trunk within the Forest Lawn Cemetery would require trimming and/or removal of mature trees that have been planted over or near the pipeline. Other streets (Seal Beach Boulevard, Los Alamitos Boulevard, Katella Avenue, and Moody Street) within the Project area also contain median landscaping that, pending final design,may need to be removed during the installation of the new pipes and/or the rehabilitation of the existing pipes. Vegetation at the Westside Pump Station (3112 Yellowtail Drive) may also need to be removed to accommodate construction access and the proposed Westside Pump Station improvements.Temporary visual impacts associated with tree trimming/removal could substantially degrade the existing visual character or the quality of the areas where tree trimming/removal would occur and be a temporary significant impact that would require implementation of mitigation measure AES MM 2 to reduce the impact to less than significant. At the Westside Pump Station, the construction activities would require the temporary removal of portions of the property fence along Yellowtail Drive to provide access for the construction equipment. The fence would be replaced in-kind after completion of construction. Construction equipment and activities at the Westside Pump Station would therefore be visible from Yellowtail Drive and adjacent residences and significantly degrade the existing visual character and quality of the site and surroundings temporarily, requiring implementation of mitigation measures AES MM 3 and AES MM 4 to reduce the impact to less than significant. 3.1.¢.2 Ope ationallmpacts At completion,the new enclosure at the Westside Pump Station building would be painted to match the color of the existing building; the appearance of new enclosure would be similar in color and height to the existing building on site. The new vent stack would be designed to look like a typical roof vent or a chimney and would not exceed 20 feet in height. Other than occupying slightly more of the area behind the fence, the new enclosure would not result in any significant permanent change to the visual character or the quality of the site or the site surroundings. All of the other proposed improvements would be sub-grade and not be visible from Yellowtail Drive behind the reconstructed fence or from adjacent residences. The operation of the improved facilities would include ongoing activities related to the operation and maintenance of the Western Regional Sewer lines and the Westside Pump Station, including: routine maintenance, cleaning of sewer lines and manholes, visual inspections, closed-circuit television and camera inspection, flow-monitoring, as-needed repairs, and chemical dosing for odor and corrosion Rehabilitation of Western Regional Sewers, Project 3-64 3-10 3.1-Aesthetics control.These operational activities are consistent with the existing operational impacts of the Western Regional Sewer lines and the Westside Pump Station. The operational impacts of the proposed Project on the visual character and the quality of the Project area and its surroundings would therefore be less than significant. AES-2: Create a new source of substantial light or glare which would adversely affect day or nighttime views in the area? 3.1.4.3 Constmetionimpacts The Orange County Municipal Code allows construction to begin as early as 7:00 a.m. OCSD would limit construction hours for the Westside Pump Station to 8:00 a.m. to 5:00 p.m., Monday through Friday,to minimize visual impacts of construction activities on adjacent residences, unless otherwise required for completion of construction activity and/or for system testing. In the event that work is required outside the allowable construction hours, adjacent property owners would be notified in advance; and a variance would be obtained from Orange County, as applicable. Thus, construction at the Westside Pump Station would not generate a new source of substantial light or glare; and impacts are less than significant. Construction activities associated with the Western Regional Sewers would occur during the day when feasible. As described in Section 2.5, construction on all major streets would occur during hours approved by the corresponding jurisdiction. Nighttime work would be required either to reduce traffic or other impacts (e.g., see Section 3.9 Noise); however, all nighttime work would require prior approval by the affected jurisdiction. Construction lighting impacts within residential areas would be considered significant temporarily due to the potential for light to spill over into residences and disrupt sleep. Mitigation measures AES MM 3 and AES MM 5 would be required where nighttime construction is necessary within adjacent residential areas throughout the Project area (Seal Beach Boulevard, Los Alamitos Boulevard, Katella Avenue, Oak Street, Sausalito Street, Cerritos Avenue, Bloomfield Street, Orange Avenue, Denni Street, Moody Street, North Western Avenue, and North Gate Road) or other sensitive receptors (e.g., the Los Alamitos Medical Center, the Seal Beach Health and Rehabilitation Center)to reduce the impacts to less than significant.See Figures 3.8-1 through 3.8-7 in Section 3.8 Land Use and Planning. 3•1.4.4 Operational Impacts The proposed Project would not include any new permanent operational lighting. Upon completion,the proposed Project would have no effect on daytime or nighttime views in the Project area. 3.1.4.5 NO Build Alternative Under the No Build Alternative, no rehabilitation and /or replacement of the Western Regional Sewers or improvements at the Westside Pump Station would occur other than the ongoing routine operations and maintenance activities as discussed in Section 2.6. The No Build Alternative would have no impacts Rehabilitation of Western Regional Sewers, Project 3-64 3-11 3.1-Aesthetics on visual quality or character within the Project area and would not result in any new source of light and glare. 3.1.5 Mitigation Measures AES MM 1: OCSD will obtain interment schedules from the Forest Lawn Cemetery and temporarily suspend construction activities for fep aaement-Gf the Los Alamitos Sub-trunk within the Forest Lawn Cemetery during interment ceremonies to minimize construction disturbances to Forest Lawn operations. Visual screening will also be installed where work will occur within and adjacent to Forest Lawn in order to reduce temporary impacts to visitors associated with construction equipment and activities. AES MM la: More disruptive construction requiring segments of open-cut trenching within the Forest Lawn property will be conducted at night,where feasible,to minimize significant impacts to visitors. AES MM 2: Based on final design and prior to removal or trimming of any tree,OCSD will identify all trees that require removal or trimming. For trees located within the existing easement, OCSD will provide in-kind replacement of landscaping for the corresponding municipality or private owner.The OCSD liaison to Forest Lawn will work with cemetery representatives during tree trimming, removal and replacement within the cemetery property. Coordination with Forest Lawn will include identifying trees to be removed and trimmed prior to cutting, discussing trees of concern and protection options, and determining species, size and planting locations for replacement specimens. The size of replacement trees will be comparable to trees removed where possible and where site conditions allow. AES MM 3: OCSD will limit construction hours for the Westside Pump Station to 8:00 a.m. to 5:00 p.m., Monday through Friday, to minimize visual impacts of construction activities on adjacent residences, unless otherwise required for completion of construction activities and system operation. In that event, adjacent property owners will be notified in advance. AES MM 4: OCSD will erect visual screening along the property walls adjacent to the pump station and across the front of the pump station during construction activities at the Westside Pump Station to minimize visual impacts of construction activities on adjacent residences. AES MM 5: Should nighttime construction be required, OCSD will require that all lighting is focused and directed onto the work area only. OCSD will monitor lighting to ensure that there is no spillover to residential areas or other sensitive receptors. Rehabilitation of Western Regional Sewers, Project 3-64 3-12 3.1-Aesthetics 3.1.6 Level of Significance after Mitigation Impacts to visual resources and aesthetics would be reduced to less than significant with the implementation of mitigation measures AES MM 1 through AES MM 5 and CUL MM 3,and CUL MM 5. Rehabilitation of Western Regional Sewers, Project 3-64 3-13 3.2-Air Quality 3.2 Air Quality This air quality assessment is based on the air modeling results provided in Appendix B. This section describes the existing regulatory framework for air quality management along with existing air quality conditions in the proposed Project area. Air quality emissions impacts associated with construction and operation of the proposed Project are described below, along with a determination of their significance in relation to applicable air quality standards. 3.2.1 Regulatory Setting 3.2.1.1 Federal The Clean Air Act of 1970, amended in 1990, is the federal law that governs air pollution. The United States (U.S.) Environmental Protection Agency (USEPA) is responsible for establishing National Ambient Air Quality Standards (NAAQS) for the following six criteria pollutants: carbon monoxide (CO), ozone (03), nitrogen dioxide (NO,), sulfur dioxide (SO,), particulate matter less than 10 microns and 2.5 microns(PMm and PM2.5),and lead (Pb). The Clean Air Act requires the USEPA to reassess the NAAQS at least every five years to determine whether adopted standards are adequate to protect public health based on current scientific evidence. States with areas that exceed the NAAQS must prepare a State Implementation Plan (SIP) that demonstrates how those areas will attain the standards within mandated time frames. The federal Clean Air Act delegates the regulation of air pollution control and the enforcement of the NAAQS to the states. In California, the task of air quality management and regulation has been legislatively granted to the California Air Resources Board (CARE), with subsidiary responsibilities assigned to air quality management districts and air pollution control districts at the regional and county levels. 3.2.1.2 State CARB, which became part of the California Environmental Protection Agency in 1991, is responsible for ensuring implementation of the California Clean Air Act of 1988, responding to the federal Clean Air Act, and regulating emissions from motor vehicles and consumer products. CARB has established California Ambient Air Quality Standards (CAAQS)for criteria pollutants which are more protective of the public health in some cases, such as PM2.3/10 and 03, compared to the NAAQS. CARB has also established standards for non-criteria pollutants including hydrogen sulfide, vinyl chloride, sulfates, and visibility-reducing particles.Table 3.2-1 summarizes the CAAQS and NAAQS for all pollutants.

California standards for ozone, carbon monoxide (except Lake Tahoe), sulfur dioxide (1-and 24-hour), nitrogen dioxide, suspended particulate matter(PM10 and PM2.$),and visibility reducing particles are values that are not to be exceeded.All others are not to be equaled or exceeded.California ambient air quality standards are listed in the Table of Standards in Section 70200 of Title 17 of the California Code of Regulations. 2. National standards (other than ozone, particulate matter, and those based on annual averages or annual arithmetic mean)are not to be exceeded more than once a year.The ozone standard is attained when the fourth highest 8-hour concentration in a year,averaged over three years,is equal to or less than the standard.For PM,the 24-hour standard is attained when the expected number of days per calendar year with a 24-hour average concentration above 150 ug/ms is equal to or less than one. For PMis, the 24-hour standard is attained when 98 percent of the daily concentrations, averaged over three years, are equal to or less than the standard. Contact USEPA for further clarification and current federal policies. 3. Concentration expressed first in units in which it was promulgated.Equivalent units given in parentheses are based upon a reference temperature of 25 degrees Celsius and a reference pressure of 760 torr.Most measurements of air quality are to be corrected to a reference temperature of 25 degrees Celsius and a reference pressure of 760 torr;ppm in this table refers to ppm by volume,or micromoles of pollutant per mole of gas. 4. National Primary Standards:The levels of air quality necessary,with an adequate margin of safety to protect the public health. S. National Secondary Standards: The levels of air quality necessary to protect the public welfare from any known or anticipated adverse effects of a pollutant. 6. On October 1,2015,the national 8-hour ozone primary and secondary standards were lowered from 0.075 to 0.070 ppm. 7. On December 14, 2012, the national annual PM, primary standard was lowered from 15 pg/m1 to 12.0 pg/ms. The existing national 24-hour PM2.s standards (primary and secondary) were retained at 35 pg/m3, as was the annual secondary standard of 15 pg/ms.The existing 24-hour PMIO standards(primary and secondary)of 150 pg/ms also were retained.The form of the annual primary and secondary standards is the annual mean,averaged over three years. Rehabilitation of Western Regional Sewers, Project 3-64 3-16 3.2-Air Quality Table 3.2-1: National and California Ambient Air Quality Standards & To attain this standard, the three-year average of the Seth percentile of the daily maximum 1-hour average at each monitor within an area must not exceed 0.100 ppm(effective January 22,2010).Note that the EPA standards are in units of parts per billion (ppb). California standards are in units of parts per million (ppm).To directly compare the national standards to the California standards the units can be converted from ppb to ppm. In this case,the national standards of 53 ppb and 100 ppb are identical to 0.053 ppm and CAN ppm,respectively. 9. On June 2,2010,the EPA established a new 1-hour S02 standard,effective August 23,2010,which is based on the three- year average of the annual 99th percentile of 1-hour daily maximum concentrations.EPA also proposed a new automated Federal Reference Method (FRM) using ultraviolet technology but will retain the older pararosanilme methods until the new FRM have adequately permeated State monitoring networks. The EPA also revoked both the existing 24-hour S02 standard of 0.14 ppm and the annual primary SO,standard of 0.030 ppm,effective August 23, 2010.The secondary S% standard was not revised at that time;however,the secondary standard is undergoing a separate review by EPA. Note thatthe new standard is in units of parts per billion(ppb).California standards are in units of parts per million(ppm). To directly compare the new primary national standard to the California standard,the units can be converted to ppm.In this case,the national standard of 75 ppb is identical to 0.075 ppm. 10. CARB has identified lead and vinyl chloride as "toxic air contaminants" with no threshold level of exposure for adverse health effects determined.These actions allow for the implementation of control measures at levels below the ambient concentrations specified for these pollutants. 11. The national standard for lead was revised on October 15,2008 to a rolling three-month average.The 1978 lead standard (1.5 pg/m3 as a quarterly average) remains in effect until one year after an area is designated for the 2008 standard, except that in areas designated nonattainment for the 1978 standard, the 1978 standard remains in effect until implementation plans to attain or maintain the 2009 standard are approved. 12. In 1989, CARE converted both the general statewide 10-mile visibility standard and the take Tahoe 30-mile visibility standard to instrumental equivalents,which are"extinction of 0.23 per kilometer"and "extinction of 0.07 per kilometer' for the statewide and Lake Tahoe Air Basin standards,respectively. The CARB is responsible for ensuring that CAAQS (Table 3.2-1) are met for certain pollutants and averaging periods. State standards are to be achieved through district-level air quality management plans that are incorporated into the State Implementation Plan. The California Clean Air Act focuses on attainment of CAAQS and requires designation of attainment and nonattainment areas with respect to these standards. The Act also requires that local and regional air districts expeditiously adopt and prepare air quality attainment plans (Clean Air Plan) if the district violates CAAQS for Oa,CO, SO,,or NO2. No locally prepared attainment plans are required for areas that violate state PM,standards.CARB is responsible for developing plans and projects that will comply with the state PMtostandards. Rehabilitation of Western Regional Sewers, Project 3-64 3-17 3.2-Air Quality 3.2.1.3 Local South Coast Air Quality Management District While CARB is responsible for the regulation of mobile emission sources within the state, local air quality management districts and air pollution control districts are responsible for enforcing standards and regulating stationary sources. The South Coast Air Quality Management District (SCAQMD) is the regional agency responsible for the regulation and enforcement of federal, state, and local air pollution control regulations in the South Coast Air Basin (SCAB), where the proposed Project is located. Specifically, SCAQMD is responsible for monitoring air quality as well as planning, implementing, and enforcing programs designed to attain and maintain CAAQS and NAAQS in the district. The programs that were developed include air quality rules and regulations that regulate stationary sources, area sources, point sources, and mobile source emissions. SCAQMD is also responsible for establishing stationary source permitting requirements and ensuring that new, modified, or relocated stationary sources do not create net emission increases. The proposed Project is subject to SCAQMD rules and regulations in effect at the time of construction. Specific rules applicable to the construction for the proposed Project include the following: SCAQMD Regulation IV, Rule 401 (2001)—Visible Emissions This rule establishes the limit for visible emissions from stationary sources. This rule prohibits visible emissions as dark as or darker than Ringlemann No. 1 for periods greater than three minutes in any hour. SCAQMD Regulation IV, Rule 402(1976)—Nuisance This rule prohibits the discharge of air pollutants from a facility that cause injury,detriment, nuisance,or annoyance to the public or damage to business or property. SCAQMD Regulation IV,Rule 403(2005)—Fugitive Dust This rule requires fugitive dust sources to implement best available control measures for all sources to ensure that all forms of visible particulate matter are prohibited from crossing any property line. SCAQMD Rule 403 is intended to reduce the amount of particulate matter entrained in the ambient air from man-made fugitive dust sources (i.e., transportation, construction, etc.) by prescribing actions to prevent, reduce, or mitigate fugitive dust emissions. SCAQMD Regulation IV, Rule 404(1986)—Particulate Matter—Concentration This regulation generally sets concentration limits for the discharge of particulate matter in the air. SCAQMD Regulation IV,Rule 431.2—Sulfur Content of Liquid Fuels The purpose of this rule is to limit the sulfur content in diesel and other liquid fuels for the purpose of both reducing the formation of sulfur oxides(SOx)and particulates during combustion and to enable the use of add-on control devices for diesel-fueled internal combustion engines. The rule applies to all Rehabilitation of Western Regional Sewers, Project 3-64 3-18 3.2-Air Quality refiners, importers, and other fuel suppliers, such as distributors, marketers, and retailers, as well as to uses of diesel, low-sulfur diesel,and other liquid fuels for stationary-source applications in the SCAB.The rule also affects diesel fuel supplied for mobile-source applications. SCAQMD Regulation XI,Rule 1110.1—Emissions from Gaseous and Liquid-Fueled Engines This regulation replaces Rule 1110.1 and regulates general emissions limits on nitrous oxides (N%), volatile organic compounds (VOCs), and CO from engines. Owners/operators of engines that exceed prescribed limits must replace them with an electric motor or remove them from service. SCAQMD Regulation XIV,Rule 1401—New Source Review of Toxic Air Contaminants This rule specifies limits for Toxic Air Contaminants (TAC) and procedures for assessing potential emissions from new permit units, relocations, or modifications to existing permit units which emit toxic air contaminants. SCAQMD has promulgated rules and regulations specific to operational emissions (non-construction) which are not directly applicable in the assessment of the significance of potential project impacts including: Air Quality Management Plan SCAQMD and the Southern California Association of Governments are responsible for preparing the air quality management plan (AQMP), which addresses federal and state Clean Air Act requirements. The AQMP details goals, policies,and programs for improving air quality in the South Coast Air Basin (SCAB). Each AQMP also addresses state and federal planning requirements and incorporates significant new scientific data, primarily in the form of updated emission inventories, ambient measurements, new meteorological episodes,and new air quality modeling tools. In December 2012, the SCAQMD adopted a 2012 Final AQMP (SCAQMD 2013), which is designed to meet applicable federal and state requirements for 03 and particulate matter. The 2012 AQMP demonstrates attainment of the federal 24-hour PM2,5 standard by 2014 in the SCAB through adoption of all feasible measures.The 2012 AQMP also updates the USEPA-approved 8-hour 03 control plan with new measures designed to reduce reliance on the Clean Air Act Section 182 (e)(5) long-term measures for N% and VOC reductions. Based on the general plans for cities and counties in the SCAB, demographic growth forecasts for various socioeconomic categories (e.g., population, housing, employment by industry) developed by the Southern California Association of Governments for their 2012 Regional Transportation Plan were used in the 2012 AQMP.The 2012 AQMP reduction and control measures, which are outlined to mitigate emissions, are based on existing and projected land use and development.The SCAQMD is in the process of developing the 2016 AQMP. Rehabilitation of Western Regional Sewers, Project 3-64 3-19 3.2-Air Quality 3.2.2 Existing Conditions 3.2.2.1 Sensitive Receptors Sensitive receptors can best be defined as those locations or areas where dwelling units or other fixed, developed sites of frequent human use occur. Sensitive receptors identified for the proposed Project include residences, lodging(hotels, motels, and similar uses), places of worship, restaurants,educational facilities (schools), recreational facilities (golf courses, parks), hospitals, and libraries within 900 feet of proposed Project segments. The majority of the Project area is urban; and,therefore, it is in a sensitive receptor "corridor" (i.e., within 900 feet of Project rights-of-way and easements), with frequent human use areas throughout all proposed segments(see Section 3.9 Noise, Figure 3.9-2 through Figure 3.9-13). 3.2.2.2 Climate and Meteorology The proposed Project is located within the SCAB (Figure 3.2-1).The SCAB is almost completely enclosed by mountains to the north and east, resulting in a fairly regular daily reversal of wind direction — offshore at night and onshore during the day. With concentrated population and industry within the SCAB,air pollution tends to accumulate and remain within this circulation pattern. Summer is a dry period over most of the state due to the semi-permanent Pacific high pressure that deflects most storms far to the north. In winter,the Pacific high pressure weakens and shifts southward. Upwelling ceases,and winter storms become frequent. According to the Western Regional Climate Center (WRCC), the most representative meteorological monitoring station within the SCAB is in Long Beach, California. The station (WRCC Station #045085, Long Beach Daugherty Field) is considered representative because of its central location within the SCAB and because of the time span for weather data collection at this location (1949 to 2015). Temperature and precipitation data recorded at this station indicate that average maximum temperatures during the winter and summer months range from 67.0 to 83.9 degrees Fahrenheit, respectively. Annual average precipitation recorded at this station is approximately 12 inches, with over 95 percent of the seasonal rainfall between October and April. Complex terrain and weather patterns within the SCAB make it a natural sink for the accumulation of emissions and sustained high pollution levels. The climate is relatively mild,with cooler temperatures and a pattern of onshore airflow along the coastal area,which improves air quality. In the inland portion of the air basin, however, a combination of abundant sunshine, warm temperatures, and poor vertical air mixing is conducive to the formation of ozone, commonly referred to as "smog." The problem is worsened by the surrounding mountains that act together with the weather to trap air pollutants. 3.2.2.3 Attainment Statas Areas can be classified within the NAAQS and CAAQS as nonattainment, maintenance, attainment, or unclassified. The geographic areas that exceed NAAQS and/or CAAQS for a criteria pollutant are considered "nonattainment" areas for that pollutant. Conversely, areas that are below a criteria pollutant standard are considered "attainment." Maintenance areas are defined as previously exceeding Rehabilitation of Western Regional Sewers, Project 3-64 3-20 3.2-Air Quality the NAAQ5 or CAAQS (nonattainment) for a criteria pollutant but are presently attaining that standard. Maintenance areas are required to develop a maintenance plan outlining steps for continued attainment over the maintenance period. Unclassified areas are those where insufficient monitoring data is available to make a determination. Table 3.2-2 summarizes the attainment status within the proposed Project area. Table 3.2-2:Attainment Status within the Project Area Criteria Pollutant _____FFederal Status State Status Carbon monoxide(CO) Maintenance Attainment Lead Attainment Attainment Nitrogen dioxide(NO2) Maintenance Attainment Ozone(03) Non-attainment Non-attainment PM" Non-attainment Non-attainment PM3o Maintenance Non-attainment Sulfur dioxide(S02) Attainment Attainment Particulate sulfate n/a Attainment Hydrogen sulfide n/a Unclassified Visibility-reducing particles n/a Unclassified Source:CARB 2015b;EPA 2015a 3.2.2.4 Existing Air Quality Monitoring Data USEPA, CARB, and local air districts select and maintain a statewide network of monitoring stations that routinely measure pollutant concentrations in the ambient air. These stations provide data to assess compliance with the NAAQ5 and CAAQS and to evaluate the effectiveness of pollution control strategies. Five monitoring stations are located within Orange County in the SCAB. Table 3.2-3 summarizes maximum monitored criteria pollutants within Orange County for which the SCAB is nonattainment/maintenance(e.g., PMis, PM10,03,CO,and NOz).

The most common forms of particulate matter are known as coarse particles with a diameter of 30 microns or less (PMio), respirable particles, and fine particles with a diameter of 2.5 microns or less (PM2,$). Fugitive dust is generated mainly from construction activities such as earth moving, paved road track-out,driving on haul roads,and excavation. The 2009 USEPA Integrated Science Assessment for Particulate Matter(USEPA. EPA/600/R-08/139F) has identified the adverse impacts of particulate matter air pollution on increased illness (morbidity) and increased death rates (mortality). Correlations have been established between elevated ambient particulate matter levels and respiratory infections, asthma attacks, and the number of hospital admissions. PM2.5 has been linked in studies to reduction in lifespan, mortality from lung cancer, cardiovascular and respiratory diseases, school and kindergarten absences, and increased asthma medication use by children and adults. TACs include 187 pollutants that are known or suspected to cause cancer or other serious health effects, such as reproductive effects or birth defects, or adverse environmental effects. Among these TACs are diesel particulates, which are one of the top three contributors, which also included 1,3 butadiene and benzene, to the potential cancer risk from motor vehicle emissions. USEPA is working with CARB and other state, local,and tribal governments to reduce releases of air toxics to the environment. 3.2.3 Thresholds of Significance The following significance criteria are based on Appendix G of the California Environmental Quality Act (CEQA) Guidelines (14 California Code of Regulations 15000 et seq.) and are used to evaluate the potential for significant proposed Project impacts related to air quality emissions. Project air quality impacts would be significant if the proposed Project would: AQ-1: Conflict with or obstruct implementation of the applicable air quality plan AQ-2: Violate any air quality standard or contribute substantially to an existing or projected air quality violation AQ-3: Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is in nonattainment under an applicable air quality standard (including releasing emissions that exceed quantitative thresholds for ozone precursors) AQ-4: Expose sensitive receptors to substantial pollutant concentrations AQ-5: Create objectionable odors affecting a substantial number of people Rehabilitation of Western Regional Sewers, Project 3-64 3-23 3.2-Air Quality 3.2.3•1 SCAQMD Significance Thresholds The SCAQMD has developed daily emissions thresholds for construction and operation of proposed projects within the SCAB as set forth in its CEQA Air Quality Handbook.The SCAQMD's thresholds are set forth in Table 3.2-4 (see page 3-25). Projects in the SCAB with emissions that exceed any of these thresholds are considered to be significant under CEQA. If a project complies with the mass daily thresholds,then compliance with ambient air quality standards is established.

KEY:lbs./day=pounds per day;ppm=parts per million;µg/m3=microgram per cubic meter Source:SCAQMD CEQA Handbook(SCAQMD 1993) 3.2.4 Impact Analysis Construction of the proposed Project has the potential to create temporary air quality emissions from soil disturbance, fugitive dust, and combustion pollutants from on-site construction equipment, personal vehicles,vendor/delivery trucks,and off-site haul trucks. Construction methods for both build alternatives would include open-cut trenching(except where noted in Section 2.5 Construction), sewer lining and manhole rehabilitation (i.e., cured-in-place pipe installation), and pump station rehabilitation. Sewer lining and manhole rehabilitation would include cured-in-place pipe (CIPP) installation using a felt truck or boiler truck with generators and air compressors. The pump station rehabilitation would involve delivery and replacement of large-volume pumping equipment for the force main, reconstruction of the wet well, and the addition of either an air scrubber or air jumper line.The proposed Project would construct sewer pipelines in a linear fashion for open-cut trenching and CIPP installation,completing approximately 50 to 150 feet per day depending on site conditions. The proposed Project would require excavation for installation of new 21- to 39-inch pipes at depths of up to 31.3 feet below ground surface (bgs).Trenches to accommodate the new pipe would be up to 7 feet wide. The construction area associated with replacement would be up to 1,000 feet long and 25 feet wide. As discussed in Section 2.5.4 Construction Schedule and Cost, the construction schedule allows sufficient time (4 years or 1,460 days) to construct each Project segment sequentially for either build alternative; however, construction of the proposed Project is anticipated to last for approximately 24 to 30 months within this time frame due to overlapping construction activities for some Project segments. Section 2.5 provides a detailed description of construction methods. Appendix B summarizes the construction method,construction equipment type, quantity of equipment, hours of operation, number of working days,and number of workers on site for each activity. Additionally, minor excavation would be required for manhole replacement/rehabilitation and on all project segments where exit/entry pits are required (e.g., for alternative construction methods discussed in Chapter 2.0)and for the improvements at the Westside Pump Station. Construction equipment and materials would be held in staging areas in parking lots, vacant lots, or segments of street lanes that are temporarily closed to minimize hauling trips and long-term disruption. Rehabilitation of Western Regional Sewers, Project 3-64 3-26 3.2-Air Quality Construction emissions can vary depending on the level of activity, the specific type of operation, and prevailing weather conditions. Construction emissions were estimated using the California Emission Estimator Model (CaIEEMod) v 2013.2.2 developed for the California Air Pollution Control Officers Association (CAPCOA) by SCAQMD and other California air districts (EIC 2013). As discussed in Section 2.5.4, the construction schedule allows sufficient time from March 2019 through March 2023 (approximately 4 years or 1,460 days) to construct each Project segment sequentially for either build alternative; however, construction activities are anticipated to last for approximately 24 to 30 months during this time frame. The 24-to 30-month time frame is anticipated due to overlapping construction activities for some Project segments. AQ-1: Conflict with or obstruct implementation of the applicable air quality plan) 3.2.4.1 Construction Impacts The SCAQMD air quality plan considered in this analysis is the SCAQMD 2012 Air Quality Management Plan (SCAQMD Plan) (SCAQMD 2013). The purpose of this plan is to demonstrate attainment of the PM2,5 24-hour standard of 35 µg/m'by 2014 within the SCAB, identify measures and actions to fulfill the 8-hour Os State Implementation Plan commitments to the USEPA to achieve emissions reductions from best available control technology (BACT), and to demonstrate attainment of the 1-hour Os CAAQS by 2022. Emissions inventories for large (4 tons annually of VOCs, NOx, oxides of sulfur, and particulates and 100 tons of CO) and small stationary sources as well as mobile sources are developed in the SCAQMD Plan. The Plan also reports pollutant concentration data collected at SCAQMD monitoring locations for comparison to the NAAQS/CAAQS. Compliance with the significance thresholds listed in Table 3.2-4 would demonstrate consistency with the SCAQMD Plan,as emissions below these thresholds would not contribute significantly to those from inventoried sources or create new or worsened violations of the NAAQS/CAAQS. Common Build Alternative Element Impacts Daily emissions from construction of the Seal Beach Blvd. Interceptor and the Orange-Western Sub- trunk, which would include the CIPP rehabilitation and manhole replacement/rehabilitation activities, would be identical under both build alternatives. Similarly,construction activities and daily emissions for the West Side Pump Station would be identical under both build alternatives(See Table 3.2-5). Overlapping construction of one or more Project segments under either build alternative is possible; however, the number of segments under construction at any given time should be limited to avoid a significant impact from construction emissions by exceeding the SCAQMD NOx threshold (see Table 3.2-5). To ensure that daily construction emissions are within the SCAQMD thresholds during overlapping construction of multiple Project segments, mitigation measure AQ MM 1 will apply (see Section 3.2.5 Mitigation Measures). By implementing AQ MM 1, impacts from construction of the proposed Project would be less than significant. Rehabilitation of Western Regional Sewers, Project 3-64 3-27 3.2-Air Quality Build Alternative 1 As shown in Table 3.2-5,daily emissions specific to Build Alternative 1 would occur with the construction of the Los Alamitos Sub-trunk and the Westside Relief Interceptor. Daily emissions associated with the Westside Relief Interceptor construction, which includes partial pipe excavation/replacement that is generally more intensive in terms of equipment usage and construction duration than CIPP activities, will be higher for Build Alternative 1 (see Appendix B Air Modeling Results). For the Los Alamitos Sub- trunk replacement/CIPP activities under Build Alternative 1, daily emissions would be lower in comparison to Build Alternative 2 due to the lesser amount of excavation involved with partial replacement of the sub-trunk and the shorter duration of construction activities (see Table 3.2-5 and Appendix B). These impacts, however, are significant and require mitigation. With implementation of mitigation measure AQ M M 1,these impacts would be less than significant. Build Alternative 2 Similarly, daily emissions specific to Build Alternative 2 would occur with the construction of the Los Alamitos Sub-trunk and the Westside Relief Interceptor. As noted above, the daily construction emissions under Build Alternative 2 would be lower for the Westside Relief Interceptor and higher for the Los Alamitos Sub-trunk in comparison to Build Alternative 1 due to the stated differences in construction activities and duration associated with CIPP rehabilitation vs. excavation (See Table 3.2-5). Overall, the daily emissions from Build Alternative 2 would be higher than for Build Alternative 1 because the increased emissions from the complete excavation/replacement of the Los Alamitos Sub- trunk would exceed the level of reduced emissions from the complete CIPP construction of the Westside Relief Interceptor. The analysis indicates that none of the emissions from construction of any of the proposed Project segments located in the SCAB for Build Alternatives 1 and 2 would exceed significance thresholds for criteria pollutants including NOw a precursor for 03, and would not conflict with or obstruct implementation of the SCAQMD Plan. Project air quality construction impacts would be significant. As discussed in Section 2.5.4, the construction schedule allows sufficient time (4 years or 1,460 days) to construct each Project segment sequentially for either build alternative, although the anticipated period of construction within this time frame is only 24 to 30 months.These impacts, however, are significant and require mitigation. With implementation of mitigation measure AQ MM 1, these impacts would be less than significant.

Sub-trunk replacement under Alternative 2 also incorporates manhole rehabilitation/replacement. 2. Bold numbers indicate exceedance of the SCAQMD significance threshold;however,this occurs only if all project segments are under construction simultaneously.With the implementation of AD MM 1,these exceedances would be avoided. 3.2.4.2 Operational Impacts Operational air quality emissions for both build alternatives would be associated with vehicle trips to complete routine maintenance; clean sewer lines and manholes; perform visual inspection utilizing closed-circuit television and camera inspection; conduct flow monitoring, as-needed repairs, and chemical dosing for odor and corrosion control; and operate the air scrubber, if included in the proposed Project.Air scrubbers control suspended particles on site and would be installed within a new enclosure adjacent to the existing building. Routine maintenance conducted after completion of the Rehabilitation of Western Regional Sewers, Project 3-64 3-29 3.2-Air Quality proposed Project would remain the same as existing maintenance activities or be reduced with use of newer equipment resulting in no significant air quality emissions. Therefore, operation of the proposed Project would not conflict with or obstruct implementation of the SCAQMD AQMP, and operational air quality emissions would be less than significant. AQ-2: Violate any air quality standard or contribute substantially to an existing or projected air quality violation? 3•2.4.3 Construction Impacts Common Build Alternative Element Impacts As previously discussed for AQ-1, daily emissions from construction of the Seal Beach Blvd. Interceptor and the Orange-Western Sub-trunk CIPP rehabilitation and manhole replacement/rehabilitation as well as the West Side Pump Station would be identical under both build alternatives(See Table 3.2-5). Compliance with these thresholds demonstrates that construction of the proposed Project would not violate air quality standards for these pollutants and would not contribute substantially to the SCAB nonattainment status for 03. Project air quality impacts would not be significant. As previously discussed, the construction schedule allows sufficient time to construct each Project segment under either build alternative, although the anticipated period of construction within this time frame is only 24 to 30 months; therefore, the number of segments under construction at any given time should be limited to avoid a significant impact from construction emissions by exceeding the SCAQMD NOx threshold. To ensure that daily construction emissions are within the SCAQMD thresholds during overlapping construction of multiple Project segments, mitigation measure AQ MM 1 would apply (see Section 3.2.5). By implementing AQ MM 1, impacts from construction of the proposed Project would be less than significant. Build Alternative 1 As previously discussed for AQ-1, daily emissions specific to Build Alternative 1 would occur with the construction of the Los Alamitos Sub-trunk and the Westside Relief Interceptor. Emissions associated with the Westside Relief Interceptor rehabilitation/replacement would be higher for Alternative 1 due to more intensive construction activities and longer construction duration compared to Build Alternative 2. For the Los Alamitos Sub-trunk construction replacement/CIPP activities under Build Alternative 1, daily emissions would be lower in comparison to Build Alternative 2 due to a lesser amount of excavation involved with partial replacement of the sub-trunk and the shorter duration of construction activities (see Appendix B). As shown in Table 3.2-5, daily emissions from construction of any of the proposed Project segments located in the SCAB would not exceed significance thresholds for criteria pollutants including 14%, a precursor for 03, for the Build Alternative 1 construction scenario after implementation of AQ MM 1. Rehabilitation of Western Regional Sewers, Project 3-64 3-30 3.2-Air Quality Build Alternative 2 As previously discussed for AQ-1, daily emissions specific to Build Alternative 2 would occur with the construction of the Los Alamitos Sub-trunk and the Westside Relief Interceptor. Emissions associated with the Westside Relief Interceptor rehabilitation would be lower for Build Alternative 2; and, for the Los Alamitos Sub-trunk, complete replacement would be higher under Build Alternative 2 due to the stated differences in construction activities and duration associated with CIPP rehabilitation and excavation. As shown in Table 3.2-5,daily emissions from construction of any of the proposed Project segments located in the SCAB would not exceed significance thresholds for criteria pollutants including NOx, a precursor for 03, for the Build Alternative 2 construction scenario after implementation of AQ MM 1. Overall, the daily emissions from Build Alternative 2 would be higher than for Build Alternative 1 because the increased emissions from the complete excavation/replacement of the Los Alamitos Sub-trunk would exceed the level of reduced emissions from the complete CIPP construction of the Westside Relief Interceptor. 3.2.4.4 Operational Impacts The operations would consist of ongoing activities related to the operation and maintenance of the Western Regional Sewer lines and the Westside Pump Station including completing routine maintenance; cleaning sewer lines and manholes; performing visual inspection utilizing closed-circuit television and camera inspection; and conducting flow monitoring, as-needed repairs, and chemical dosing for odor and corrosion control. Operation of the proposed Project would result in no significant change of operational air quality emissions. Therefore, operation of the proposed Project would not contribute to the SCAB nonattainment status for 03 or a projected violation, and operational air quality emissions would be less than significant. AQ-3: Result In a cumulatively considerable net Increase of any criteria pollutant for which the project region is in nonattainment under an applicable air quality standard (including releasing emissions that exceed quantitative thresholds for ozone precursors)? 3.2.4.5 Construction Impacts As shown in Table 3.2-2, the SCAB is classified as nonattainment for 03 (NAAQS and CAAQS), PMi,s (NAAQS and CAAQS), and PM3o (CAAQS). Cumulative emissions from motor vehicles, off-road equipment,commercial and industrial facilities, and other emission sources all contribute to the region's poor air quality. Common Build Alternative Element Impacts As previously discussed for AQ-1 and AQ-2, daily emissions from construction of the Seal Beach Blvd. Interceptor and the Orange-Western Sub-trunk CIPP rehabilitation and manhole replacement/rehabilitation as well as the Westside Pump Station would be identical under both build alternatives(see Table 3.2-5). Rehabilitation of Western Regional Sewers, Project 3-64 3-31 3.2-Air Quality Compliance with these thresholds demonstrates that construction of the proposed Project would not result in a cumulatively considerable increase of any criteria pollutant including NO, a precursor for O3, for which the SCAB is in nonattainment. Project air quality impacts would not be significant. As previously discussed,the construction schedule allows sufficient time to construct each Project segment under either build alternative, although the anticipated period of construction within this time frame is only 24 to 30 months; therefore, the number of segments under construction at any given time should be limited to avoid a significant impact from construction emissions by exceeding the SCAQMD NOx threshold. To ensure that daily construction emissions are within the SCAQMD thresholds during overlapping construction of multiple Project segments, mitigation measure AQ MM 1 would apply (see Section 3.2.5). By implementing AQ MM 1, impacts from construction of the proposed Project would be less than significant. Build Alternative 1 As previously discussed in AQ-1 and AQ-2, daily emissions specific to Build Alternative 1 would occur with the construction of the Los Alamitos Sub-trunk which would be lower in comparison to Build Alternative 2 due to a lesser amount of excavation involved with partial replacement of the sub-trunk and the shorter duration of construction. Daily emissions would be higher for the Westside Relief Interceptor due to more intensive construction activities and longer construction duration compared to Build Alternative 2. As shown in Table 3.2-5, daily emissions from construction of any of the proposed Project segments located in the SCAB would not exceed significance thresholds for criteria pollutants including NOx a precursor for 03,for the Build Alternative 1 construction scenario after implementation of AQ MM 1. Build Alternative 2 As previously discussed for AQ-1 and AQ-2,daily emissions specific to Build Alternative 2 would occur with the construction of the Los Alamitos Sub-trunk and the Westside Relief Interceptor. Emissions associated with the Westside Relief Interceptor rehabilitation would be lower for Build Alternative 2; and,for the Los Alamitos Sub-trunk, emissions would be higher under Build Alternative 2 due to the stated differences in construction activities and duration associated with CIPP rehabilitation vs. excavation/replacement. As shown in Table 3.2-5,daily emissions from construction of any of the proposed Project segments located in the SCAB will not exceed significance thresholds for criteria pollutants including NO, a precursor for 03, for the Build Alternative 2 construction scenario. Overall, the emissions from Build Alternative 2 would be higher than for Build Alternative 1 because the increased emissions from the complete excavation/replacement of the Los Alamitos Sub-trunk would exceed the level of reduced emissions from the complete CIPP construction of the Westside Relief Interceptor. These impacts would be significant and require implementation of mitigation measure AQ MM 1 to reduce impacts to less than significant. Rehabilitation of Western Regional Sewers, Project 3-64 3-32 3.2-Air Quality 3.2.4.6 Operational Impacts The air quality emissions from operations for both of the build alternatives would consist of ongoing activities related to operation and maintenance of the Western Regional Sewer lines and the Westside Pump Station including completing routine maintenance; cleaning sewer lines and manholes; performing visual inspection utilizing closed-circuit television and camera inspection; and conducting flow monitoring, as-needed repairs, and chemical dosing for odor and corrosion control. The operation of the proposed Project would result in no significant change of operational air quality emissions. Therefore, the operation of the proposed Project would not result in a cumulatively considerable net increase in 03 from the NOx emissions, and impacts would be less than significant. AQ4: Expose sensitive receptors to substantial pollutant concentrations? 3.2.4.7 Construction Impacts The SCAQMD has established local significance thresholds (LSTs), which were developed based on the ambient concentrations of a pollutant for each source receptor area (SRA) and the distance of the pollutant source to the nearest sensitive receptor, which includes residences, lodging (hotels, motels, and similar uses), places of worship, restaurants, educational facilities (schools), recreational facilities (golf courses, parks), hospitals,and libraries.Table 3.2-6 summarizes the SCAQMD LSTs forthe following pollutants: NOx, CO, PMm, and PM2s. SCAQMD has not established local thresholds for reactive organic gases (ROGs). The SCAQMD recommends the evaluation of localized pollutant impacts to sensitive receptors in the immediate vicinity of the proposed Project as a result of construction activities. The Project area is urban, with heavy development and numerous sensitive receptors within the vicinity of the proposed Project.The nearest sensitive receptors are generally located approximately 25 feet or less from the proposed improvements. Construction of the proposed sewer pipelines is considered a linear activity and would continuously move during the project construction phases. Approximately 50 to 150 feet of construction would occur per day, depending on site conditions; therefore, construction activities would be temporary and of short duration at any one location in the Project area. Project construction emissions were evaluated against LSTs for a single calendar day rather than averaged over the entire construction duration of each project segment as they were for the SCAQMD significance threshold analysis. This approach focuses on activities taking place within a smaller project footprint of 1 acre or less that is the basis of establishing LSTS within a given SRA. Common Build Alternative Element Impacts Under both build alternatives, single-day emissions from the construction of the Seal Beach Blvd. Interceptor and the Orange-Western Sub-trunk, which would include the CIPP rehabilitation and manhole replacement/rehabilitation activities, would be identical, and their associated impacts would be less than significant. Similarly, construction activities for the Westside Pump Station and single-day emissions would be identical under both build alternatives (see Table 3.2-5), and their associated impacts would be less than significant. Rehabilitation of Western Regional Sewers, Project 3-64 3-33 3.2-Air Quality Build Alternative 1 As shown in Table 3.2-6, single-day emissions from the construction of the Los Alamitos Sub-trunk and the Westside Relief Interceptor at a representative 1-acre construction site would vary depending on the particular construction involved, with higher emissions generated by the complete excavation/replacement activities compared to CIPP activities. The estimated single-day emissions for a representative construction area of 1-acre or less that are specific to Build Alternative 1 would occur where excavation/replacement vs. CIPP rehabilitation of the Westside Relief Interceptor and the Los Alamitos Sub-trunk, respectively,would occur. This is reflected in the range of daily emissions of NOx, CO, and PM,,shown in Table 3.2-6. Variability in estimated PM,emissions in comparison to Alternative 2 was eliminated through rounding. Conversely, the construction emissions evaluation for the other project segments did not produce a quantifiable difference compared to Build Alternative 2, because the same activities would occur on a given day under either alternative. As shown in Table 3.2-6,daily emissions from construction of any of the proposed Project segments located in the SCAB would not exceed local significance thresholds for criteria pollutants, including NO, a precursor for Oj, for the Build Alternative 1 construction scenario. As a result, impacts would be less than significant and no mitigation is required.

Build Alternative 2 The estimated single-day emissions for a representative construction area of 1 acre or less specific to Build Alternative 2 would occur where excavation/replacement vs. CIPP rehabilitation of the Westside Relief Interceptor would occur. This is reflected in the range of daily emissions of NOx, CO, and PMto shown in Table 3.2-6. Variability in comparison of estimated PM2,s emissions in comparison to Build Alternative 1 was eliminated through rounding. Although not unique to Build Alternative 2, estimated emissions from the complete excavation/replacement of the Los Alamitos Sub-trunk for a representative 1-acre or less construction area would be at the upper end of the range for Build Alternative 1,as shown in the table. As previously discussed, the construction emissions evaluation for the other project segments did not produce a quantifiable difference compared to Build Alternative 2 because the same activities would occur on the first day under either alternative. As shown in Table 3.2-6, daily emissions from construction of any of the proposed Project segments located in the SCAB would not exceed local significance thresholds for criteria pollutants, including NOw a precursor for Oa, for the Build Alternative 2 construction scenario.The proposed Project would comply with the thresholds established by the LSTs, which is sufficient to demonstrate that construction of the proposed Project segments in the SCAB under Build Alternative 1 and Build Alternative 2 would not result in exposure of sensitive receptors to substantial pollutant concentrations; therefore, impacts to sensitive receptors would be less than significant. 3.2.4.8 Operational impacts Operational air quality emissions would be associated with vehicle trips to complete routine maintenance; clean sewer lines and manholes; perform visual inspection utilizing closed-circuit Rehabilitation of Western Regional Sewers, Project 3-64 3-35 3.2-Air Quality television and camera inspection; conduct flow monitoring, as-needed repairs, and chemical dosing for odor and corrosion control; and operate the air scrubber, if included in the proposed Project. Air scrubbers control suspended particles on site and would be installed within a new enclosure adjacent to the existing building. Completion of the proposed Project would result in no significant change of operational air quality emissions. The operational activities that would generate potential air quality emissions would be from mobile sources, generally one to two vehicles twice a month. The proposed Project would not increase the number of trips above current conditions and would not generate sufficient emissions to create an air quality violation. In addition,over time the fleet vehicles would have cleaner engines, which would reduce overall operational emissions. Operational impacts are not anticipated, and operation of the proposed Project would not expose sensitive receptors to substantial pollutant concentrations. AQ-S: Create objectionable odors affecting a substantial number of people? 3.2.4.9 Construction Impacts Odors can be offensive and annoying to the public but seldom cause physical harm. Project construction emissions of dust from excavated soil have the potential to generate objectionable odors as well as fumes from diesel and gasoline equipment and asphalt paving material; however, odors from these sources would be localized and generally confined to the construction area. Replacement of the proposed sewer pipelines would be considered a linear project, completing approximately 50 to 150 feet of pipeline per day, depending on site conditions. Therefore, construction activities would not occur in one location for an extended period of time. In addition, odors from the existing pipelines would not be exposed, since most pipes would be left in place and a new pipeline would be constructed on a new alignment. In replacement areas the trench would be covered daily with steel plating or other similar material and would minimize potential odors from excavations. In addition, areas would be paved over as the construction moved along in a linear fashion. Common Build Alternative Element Impacts A similar potential for odors during construction would occur for the Orange-Western Sub-trunk, the Seal Beach Blvd. Interceptor, and the Westside Pump Station; however, the pump station is located inside a building, minimizing any potential odors from construction activities. Build Alternative 1 The potential for odors during construction under Build Alternative 1 would be reduced along the Los Alamitos Sub-trunk, as less open excavation and pipe installation would occur, and increased along the Westside Relief Interceptor, as more open excavation and pipe installation would occur in comparison to Build Alternative 2; however, the total length of open-cut trenching and potential exposure to odors would be reduced. Construction odor impacts would be less than significant. Rehabilitation of Western Regional Sewers, Project 3-64 3-36 3.2-Air Quality Build Alternative 2 The potential for odors during construction under Build Alternative 2 would be increased along the Los Alamitos Sub-trunk, as more open excavation and pipe installation would occur, and reduced along the Westside Relief Interceptor,as more open excavation and pipe installation would occur than under Build Alternative 1. In general, a higher potential for odors would be associated with Build Alternative 2, which entails more overall open-trench activities for the complete excavation/replacement of the Los Alamitos Sub-trunk. Odors during construction would not create an odor nuisance pursuant to SCAQMD Rule 402, as they would be temporary and limited to 50- to 100-foot sections during the construction day where excavation activities occur.Construction odor impacts would be less than significant. 3.2.4.10 CIP rntionalimpacts Odors most often reported to the SCAQMD are associated with transfer station/recycling, auto body facilities, foundry/metal processing, wastewater/water treatment, and landfills, which together comprise approximately 55 percent of all complaints (Curren 2012). Operation of the proposed Project would include vehicle trips to complete routine maintenance; clean sewer lines and manholes; perform visual inspection utilizing closed-circuit television and camera inspection; conduct flow monitoring, as- needed repairs, and chemical dosing for odor and corrosion control; and operate the air scrubber, if included in the proposed Project. In addition to chemical dosing, an air scrubber controls suspended particles on site and would help to reduce any odors associated with operations. In addition, the air scrubber would be installed within a new enclosure adjacent to the existing building. Completion of the proposed Project would result in no significant change of operational air quality emissions and would not create an odor nuisance pursuant to SCAQMD Rule 402.Therefore,odor impacts are not anticipated during operation of the proposed Project. 3.2.4.11 NO BuildAlternative Under the No Build Alternative, no rehabilitation or replacement of the Western Regional Sewers or improvements at the Westside Pump Station would occur other than routine operations and maintenance activities as discussed in Section 2.6. The No Build Alternative would result in no increase in emissions and would have no impact on air quality. 3.2.5 Mitigation Measures Although not anticipated, emissions from simultaneous construction of all proposed Project segments would result in significant impacts under significance thresholds AQ-1, AQ-2, AQ-3; and implementation of mitigation measure AQ MM 1 is required. The proposed Project would need to adhere to SCAQMD rules and regulations during construction, which could help to minimize significant air quality emission impacts. Rehabilitation of Western Regional Sewers, Project 3-64 3-37 3.2-Air Quality AQ MM 1: OCSD shall require its construction contractor, either through the use of scheduling, sequencing of equipment usage, or other means, to demonstrate that construction- related activities for all Project segments will not generate daily emissions exceeding the SCAQMD NOxthreshold shown in Table 3.2-5 3.2.6 Level of Significance after Mitigation Implementation of mitigation measure AQ MM 1 for impacts AQ-1, AQ-2, and AQ-3 would reduce NOx construction emissions to less than significant.

Under Section 7 of this act, federal agencies are required to consult with the United States (U.S.) Fish and Wildlife Service (USFWS) and National Oceanic and Atmospheric Administration, National Marine Fisheries Service (NOAA Fisheries)to ensure that they are not undertaking,funding, permitting, or authorizing actions likely to jeopardize the continued existence of listed species or destroy or adversely modify designated critical habitat. Critical habitat is defined as geographic locations critical to the existence of a threatened or endangered species. Section 9 of the Federal Endangered Species Act prohibits the take of threatened or endangered species, which is defined as "harass, harm, pursue, hunt, shoot, wound, kill, trap, capture or collect or any attempt at such conduct." Clean Water Act Sections 401 and 404 Under Section 404 of the Clean Water Act, the U.S. Army Corps of Engineers (USACE) regulates the discharge of dredged and fill materials into waters of the United States.As defined in 33 Code of Federal Regulations 328.3, these waters generally include wetlands and other waters, such as intrastate lakes, rivers, streams, muciflats, and tributaries to those waters. The U.S. Environmental Protection Agency (USEPA) shares responsibility over waters of the United States, with USACE overseeing the Section 404 permit program. In addition, Executive Order (EO) 11990 directs federal agencies to observe a "no net loss" of wetlands in order to "minimize the destruction, loss, or degradation of wetlands, and to preserve and enhance the natural and beneficial values of wetlands." Section 401 of the Clean Water Act and the Porter-Cologne Act provide the California Regional Water Quality Control Boards' (RWQCB) regulatory authority.The RWQCBs administer Section 401 of the Clean Water Act through water quality certification of any activity that may result in a discharge to jurisdictional waters of the United States. The RWQCBs may also regulate discharges to waters of the State under the Porter-Cologne Act. Rehabilitation of Western Regional Sewers, Project 3-64 3-40 3.3-Biological Resources Migratory Bird Treaty Act Pursuant to the Migratory Bird Treaty Act (MBTA) of 1918, federal law prohibits the taking of migratory birds, their nests, or their eggs (16 United States Code [U.S.C.], Section 703). In 1972, the META was amended to include protection for migratory birds of prey (e.g., raptors). The USFWS enforces the Migratory Bird Treaty Act(16 U.S.C.703-711). 3.3•1s State California Endangered Species Act The California Endangered Species Act states that "all native species of fishes, amphibians, reptiles, birds, mammals, invertebrates, and plants, and their habitats, threatened with extinction and those experiencing a significant decline which, if not halted, would lead to a threatened or endangered designation, will be protected or preserved"(California Department of Fish and Wildlife [CDFW] 2014a). Section 2081 of the California Endangered Species Act addresses the issuance of Incidental Take Permits from CDFW, which is required for projects that could result in the "take" of a state-listed threatened or endangered species. Under the California Endangered Species Act, "take" is defined as"to hunt, pursue, capture, or kill or to attempt to hunt, pursue, catch, capture, or kill any species determined to be endangered or threatened."A Section 2081 permit is issued when a project determination is consistent with the issued Biological Opinion, an opinion issued by USFWS or NOAA Fisheries during formal Section 7 consultation under the Federal Endangered Species Act. CDFW is responsible for all state-listed plant and animal species under the California Endangered Species Act (Fish and Game Code Sections 2050- 2116). California Fish and Game Code:Fully Protected Species(3511.4700,5050,and 55151 The State of California attempted to protect species considered rare or facing possible extinction by enacting California Fish and Game Code Sections 3511, 4700, 5050, and 5515 in the 1960s. This legislation designated fish, mammal, amphibian, and reptile species as "Fully Protected" by the state. The taking or possessing of fully protected species is prohibited unless a license or permit is obtained. California Fish and Game Code: Lake or Streambed Alteration Agreement(16021 Under Section 1602 of the California Fish and Game Code, the CDFW regulates activities that would substantially divert or obstruct the natural flow or substantially change the hydrological dynamics of rivers, streams and lakes. CDFW enforces Section 1602 of the California Fish and Game Code and prohibits activities to any bed, channel,or bank of any river,stream,or lake or the deposition or disposal of debris,waste, or other material containing crumbled,flaked, or ground pavement,where it may pass into any river, stream, or lake. A Lake or Streambed Alteration Agreement is required for activities within its jurisdictional area. Rehabilitation of Western Regional Sewers, Project 3-64 3-41 3.3-Biological Resources California Fish and Game Code 3503 Under Section 3503 of the California Fish and Game Code, it is unlawful to take, possess, or needlessly destroy the nest or eggs of any bird, except as otherwise provided by code or regulation. 3.3-1•3 Local Orange County Transportation Authority Habitat Conservation Plan/Natural Community Conservation Plan The Orange County Transportation Authority (OCTA) Habitat Conservation Plan/Natural Community Conservation Plan (OCTA HCP/NCCP) sets forth a proposed conservation strategy that would be implemented by the OCTA in cooperation with state and federal agencies and participating landowners in Orange County. The geographic planning area for the HCP/NCCP includes all of Orange County (2009 Planning Agreement, Section 4.1). The proposed conservation strategy focuses on long-term protection and management of multiple natural communities that provide habitat essential to the survival of a broad array of wildlife and plant species. Activities covered within the OCTA HCP/NCCP Planning Agreement that are located within the proposed Project site include the Interstate (1-) 405 improvement project (identified as Project K in the planning agreement [2009]) between 1-605 and State Route (SR-) 55.The improvements would add new lanes to this section of 1-405. The project would make best use of available freeway property, update interchanges, and widen various local overcrossings according to city and regional plans. The improvements would be coordinated with other planned 1-405 improvements in the 1-405/SR-22/1-605 interchange area to the north and 1-405/SR-73 improvements to the south. The Final Environmental Impact Report/Environmental Impact Statement for the NCCP/HCP is scheduled for release by the end of 2016. City of Seal Beach Municipal Code The City of Seal Beach Municipal Code 9.40.010 (City Trees and Structures) states that no person shall remove, cut, destroy, relocate, trim, prune, deface, burn, or otherwise injure any tree, hedge, plant, shrub or flower growing upon city property. City of Seal Beach Street Tree Master Plan The City of Seal Beach makes every effort to ensure the quality and maintenance of its trees.The policy regarding the removal and replacement of existing trees in public right-of-way states that the City is responsible for removal of street trees within the public right-of-way, and no street tree shall be removed without the approval from the City's Public Works Director, Public Works Supervisor, and Tree Advisory Board. Furthermore, all street trees removed shall be replaced unless the Director of Public Works and /or City Representative determines it is in the interest of safety or sound horticultural practices not to replace the tree.All replacement trees shall be consistent with the adopted Street Tree Master Plan. Rehabilitation of Western Regional Sewers, Project 3-64 3-42 3.3-Biological Resources City of Los Alamitos General Plan The City of Los Alamitos General Plan Open Space, Recreation, and Conservation Element (City of Los Alamitos 2015) provides direction regarding the conservation, development, and utilization of natural resources. "Goal 3: Natural, historic, and cultural resources that are preserved and promoted as key features for civic pride and identity. "Policy 3.2: Urban Forest. Maintain and enhance a diverse and healthy urban forest on public and private lands. Incorporate and preserve mature and specimen trees at key gateways, landmarks,and public facilities." City of Los Alamitos Municipal Code The City of Los Alamitos Municipal Code states that only authorized city personnel or agents shall trim, alter or remove any City Tree°. And it is unlawful to damage,cut, carve, etch, hew or engrave, poison or injure the bark or root system of any City Tree except for standard root pruning or shaving procedures performed by authorized city personnel or agents. 3.3.2 Existing Conditions The proposed Project site is located within a developed urban area in paved public rights-of-way within city streets or Orange County Sanitation District(OCSD)easements that do not support native habitat of any identified special status species, riparian habitat, or other sensitive natural communities. Parks and recreation areas exist within and nearby the Project area that may provide habitat for wildlife, such as birds. The proposed alignment would cross underneath the Bixby Channel, Carbon Creek, and Moody Creek; however, all of these are concrete-lined, and none contain any riparian or sensitive natural communities(including wetlands). 33.3 Thresholds of Significance The following significance criterion is based on Appendix G of the California Environmental Quality Act (CEQA)Guidelines(14 California Code of Regulations 15000 et seq.)and is used to evaluate the potential for significant project impacts related to biological resources. Project impacts on biological resources would be significant if the proposed Project would: 3I0-1: Conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance. " Defined as any tree growing on property owned or controlled by the city,including but not limited to all streets,parkways, public places,and all easements granted to the city and/or the public Rehabilitation of Western Regional Sewers, Project 3-64 3-43 3.3-Biological Resources B10-2: Conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan,or other approved local,regional, or state habitat conservation plan? All other significance criteria for Biological Resources from Appendix G of the CEQA Checklist, as evaluated in Section 4.4 of the Initial Study for the proposed Project(See Appendix A),were determined to result in either no impact or less than significant impacts and are not discussed any further within this Environmental Impact Report (EIR). The significance criteria eliminated from further consideration include: • Having a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special status species in local or regional plans, policies, or regulations, or by the California Department of Fish and Wildlife or U.S. Fish and Wildlife Service • Having a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, and regulations or by the California Department of Fish and Wildlife or U.S. Fish and Wildlife Service • Having a substantial adverse effect on federally protected wetlands as defined by Section 404 of the Clean Water Act (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal,filling,hydrological interruption,or other means • Interfering substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites 3.3.4 Impact Analysis The differences between the two build alternatives are minor. Thus, no differences between the two build alternatives are anticipated as they relate to impacts to biological resources, and the impacts described in this section are the same for Build Alternative 1 and Build Alternative 2. Additionally, construction of the proposed Project with either build alternative would not conflict with the OCFA HCP/NCCP. 810-1: Conflict with any local policies or ordinances protecting biological resources,such as a tree preservation policy or ordinance? 3.3.4•1 Construction Impacts Tree Removal The Cities of Los Alamitos and Seal Beach are the only cities with tree protection ordinances. However, all proposed work within the City of Seal Beach is rehabilitation. No impacts to trees would occur within the City of Seal Beach. Rehabilitation of Western Regional Sewers, Project 3-64 3-44 3.3-Biological Resources Replacement of the Westside Relief Interceptor pipeline within the City of Los Alamitos on Los Alamitos Boulevard and Katella Avenue may require removal of trees.As described in Section 2.5,where feasible, new alignments for replacement pipelines would be within the center lanes/medians lanes of existing streets to minimize traffic disruption during construction; however, due to existing utility placement or other constraints, replacement lines could end up within the median and require the removal of trees protected by the Los Alamitos tree protection ordinance. Impacts to trees protected by a tree protection ordinance would be considered a significant impact. Additionally, mature trees are present within the Forest Lawn Memorial Park cemetery that could be impacted by the project. The proposed alignment for the Los Alamitos Sub-trunk would extend from Denni Street north of Lincoln Avenue to Guardian Drive just north of Cypress Drive and could impact the trees located between Cypress Drive and Lincoln Avenue between the two parking lots. Impacts to these trees, including removal, trimming, and pruning, are potentially significant and could conflict with the local policies or the ordinances protecting tree preservation policy. These impacts would be less than significant with the incorporation of mitigation measures AES MM 2 and BID MM 1. The Project area is highly urbanized with very little wildlife habitat. Landscaped trees and shrubs may provide nesting habitat for birds, and construction activities may affect nesting birds protected under the MBTA and California Fish and Game Code Section 3503 during tree trimming or removal.The MBTA and Section 3503 make it illegal for anyone to "takes" any migratory bird, or the parts, nests,or eggs of such a bird. Disturbance of active nests during construction would be considered a significant impact under the MBTA and the California Fish and Game Code. With implementation of BID MM 1, impacts would be less than significant. 3.3.4•2 Operatianallmpacts Operations would consist of ongoing activities related to operation and maintenance of the Western Regional Sewer lines and Westside Pump Station including completing routine maintenance; cleaning sewer lines and manholes; performing visual inspections utilizing closed-circuit television and camera inspection; and conducting flow-monitoring, as-needed repairs, and chemical dosing for odor and corrosion control.Operational impacts on biological resources would be less than significant. 3.3.4.3 No BuildAlternative Under the No Build Alternative, there would be no rehabilitation or replacement of the Western Regional Sewers or improvements at the Westside Pump Station other than routine operations and maintenance activities as discussed in Section 2.6. The No Build Alternative would have no impacts on biological resources protected by policy or ordinance. s The term"take"means to harass,harm,pursue,hunt,shoot,wound,kill,trap,capture,orcollect orto attemptto engage in any such conduct. Rehabilitation of Western Regional Sewers, Project 3-64 3-45 3.3-Biological Resources BIO-2: Conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan,or other approved local,regional, or state habitat conservation plan? 33.4.4 COnstructionlmpacts OCTA HCP/NCCP Construction of the proposed Project would not conflict with the OCTA HCP/NCCP.Although a portion of the proposed Project site (i.e., Seal Beach Blvd. Interceptor) is located within the OCTA HCP/NCCP planning area (i.e., 1-405), it occurs within an area entirely hardscaped with concrete that has little or no biological value.Additionally,the Seal Beach Blvd. Interceptor sewer line would be rehabilitated in place and would not require any open-cut construction. No other impacts to special status species or sensitive natural communities (including wetlands) are anticipated because none are anticipated to occur within the Project area; nor would the proposed Project interfere substantially with the movement of wildlife species. 3.3.4.5 Operational impacts Operations would consist of ongoing activities related to operation and maintenance of the Western Regional Sewer lines and the Westside Pump Station including completing routine maintenance; cleaning sewer lines and manholes; performing visual inspections utilizing closed-circuit television and camera inspection; and conducting flow-monitoring, as-needed repairs, and chemical dosing for odor and corrosion control.Operational impacts on any HCP/NCCP would be less than significant. 33.4.6 No Build Alternative Under the No Build Alternative, there would be no rehabilitation or replacement of the Western Regional Sewers or improvements at the Westside Pump Station other than routine operations and maintenance activities as discussed in Section 2.6. The No Build Alternative would have no impacts on any HCP/NCCP. 3.3.5 Mitigation Measures AES MINI 2 Based on final design and prior to removal or trimming of any tree,OCSD will identify all trees that require removal or trimming. For trees located within the existing easement, OCSD will work with property owners regarding in-kind replacement landscaping for the corresponding municipality or private owner. The OCSD liaison to Forest Lawn will work with cemetery representatives during tree trimming, removal and replacement within the cemetery property. Coordination with Forest Lawn will include identifying trees to be removed and trimmed prior to cutting, discussing trees of concern and protection options, and determining species, size and planting locations for replacement specimens. The size of replacement trees will be comparable to trees removed where possible and where site conditions allow. Rehabilitation of Western Regional Sewers, Project 3-64 3-46 3.3-Biological Resources BID MM 1 Shrub and tree trimming and/or removal activities associated with the proposed Project shall be conducted outside the nesting season (February 15 through July 15). However, if shrub and tree removal must occur during the nesting season, a qualified wildlife biologist (as determined by California Department of Fish and Wildlife) shall conduct preconstruction surveys for nesting birds within suitable nesting habitat in the proposed Project area including a 300-foot buffer around the construction limits.The nesting bird surveys shall be conducted one week before initiation of construction activities within those habitats. If no active nests are detected during surveys, construction may proceed. If active nests are detected, then a no-disturbance buffer shall be established around nests identified during preconstruction surveys. The extent of the no- disturbance buffer shall be 50 feet for non-raptors and 300 feet for raptors. These buffer distances may be altered by a qualified biologist depending on the level of noise or construction disturbance, line of sight between the nest and the disturbance, ambient levels of noise and other disturbances, and other topographic or artificial barriers.These buffers shall be maintained until after the breeding season has ended or until the biologist determines that the young have fledged. Within this buffer, all nonessential construction activities (e.g., equipment storage, meetings) shall be avoided; however, construction activities can proceed if the biologist determines that the nesting birds are not likely to abandon the nest during construction. 3.3.6 Level of Significance after Mitigation Impacts to biological resources would be reduced to less than significant with the implementation of mitigation measures AES MM 2 and BID MM 1. Rehabilitation of Western Regional Sewers, Project 3-64 3-47 3.4-Cultural Resources 3.4 Cultural Resources This section identifies cultural resources along the alignment for the proposed Project area, the significance of those resources, and addresses potential impacts to those resources. Cultural resources may include, but are not limited to, prehistoric and historic period artifacts, sites, monuments, landscapes, features, structures, graves, buildings, and entire districts. '- add t BR, Pub"s Resewees Cede § 21974). This analysis has been prepared in accordance with California Environmental Quality Act (CECA) Guidelines, Section 15064.5, and is supported by the Cultural Resources Constraints Report(see Appendix C). The paleontological resources analysis presents information pertaining to the existing conditions of geologic features underlying the Project area and the potential for the presence of paleontological resources within the Project area. The analysis is based on a collection of data from the Los Angeles Museum of Natural History, Page Museum, Cooper Center, and other institutions and data maintained by Paleo Solutions, Inc.(PSI). The assessment of cultural resources in the Project area is based on a records search of existing resources along the proposed Project alignment and an intensive field survey of the Project area. On June 9 and October 19, 2015, PSI conducted records searches of the California Historical Resources Information System at the California South Central Coastal Information Center, housed at California State University, Fullerton. The records search and field survey allowed opportunity to identify the presence and assess the significance of cultural resources, and to recommend appropriate mitigation measures to avoid or minimize impacts to these resources. The field survey along the proposed Project alignment was conducted by PSI on June 25 and October 5,2015. 3.4.1 Regulatory Setting The proposed Project is undertaken in compliance with regulatory standards set forth by CEQA, the California Public Resources Code,the California Health and Safety Code,and the Orange County General Plan and,where applicable, standards set forth by municipalities within the Project area. 3.4.1.1 Federal National Historic Preservation Act The National Historic Preservation Act (NHPA) (16 United States Code [U.S.C.] 470 et seq.) establishes the nation's policy for historic preservation and sets in place a program for the preservation of historic properties by requiring federal agencies to consider the effects of all federally funded or permitted projects on historic properties. Specifically, Section 106 of the NHPA requires federal agencies to take into account the effects projects may have on sites listed on or eligible for listing on the National Rehabilitation of Western Regional Sewers, Project 3-64 3-48 3.4-Cultural Resources Register of Historic Places (NRHP or National Register). Federal agencies issuing permits for the proposed project will be required to comply with NHPA requirements. Executive Order 11593:"Protection and Enhancement of the Cultural Environment' Executive Order 11593 (36 Federal Register 8921) orders the protection and enhancement of the historic and cultural environment of the United States by requiring federal agencies to(1)administer the cultural properties under their control in a spirit of stewardship and trusteeship for future generations; (2) initiate measures necessary to direct their policies, plans, and programs in such a way that federally owned sites, structures, and objects of historical, architectural, or archaeological significance are preserved, restored, and maintained for the inspiration and benefit of the people; and (3) in consultation with the Advisory Council on Historic Preservation, institute procedures to assure that federal plans and programs contribute to the preservation and enhancement of non-federally owned sites, structures,and objects of historical,architectural,or archaeological significance(16 U.S.C.470-1). National Register of Historic Places The NRHP is the nation's official list of districts, sites, objects, buildings, and structures significant in American history, architecture, archeology, engineering, and culture. The National Register is overseen by the National Park Service and requires that a property or resource eligible for listing in the register meet one or more of the following four criteria at the national, state, or local level to ensure integrity and obtain official designation: • The property is associated with events that have made a significant contribution to the broad patterns of American history. • The property is associated with the lives of persons significant to the American past. • The property embodies the distinctive characteristics of a type, period, or method of construction, or represents the work of a master,or possesses high artistic values, or represents a significant and distinguishable entity whose components lack individual distinction. • The property has yielded,or is likely to yield, information important to prehistory or history. • In addition to meeting at least one of these four criteria, listed properties must also retain sufficient physical integrity of those features necessary to convey its significance. The National Register criteria recognize the following seven aspects or qualities that, in various combinations, define integrity: (1) location, (2) design, (3) setting, (4) materials, (5) workmanship, (6) feeling, and (7) association. Properties are nominated to the National Register by the state historic preservation officer of the state in which the property is located, by the federal preservation officer for properties under federal ownership or control, or by the tribal preservation officer if on tribal lands. Listing in the National Register provides formal recognition of a propertys historic,architectural,or archaeological significance based on national standards used by every state. Once a property is listed on the National Register, it Rehabilitation of Western Regional Sewers, Project 3-64 3-49 3.4-Cultural Resources becomes searchable in the NRHP database of research information. Documentation of a property's historic significance helps encourage preservation of the resource. 3.4.1.2 State California Environmental Quality Act Proposed project plans are subject to CEOA analysis as it pertains to cultural resources; and lead agencies or project proponents, such as Orange County Sanitation District (OCSD), are required to comply with the CEQA Statute and Guidelines (as amended through 2016) by determining if the project will cause a substantial adverse change in the significance of a "historic resource," as defined in Title 14 of the California Code of Regulations§ 15064.5[a]. For CEQA purposes, a cultural resource is considered a historical resource if the resource is 50 years old or older; possesses integrity of location, design, setting, materials, workmanship, feeling, and association; and meets the requirements for listing on the California Register of Historical Resources (CRHR) including(Title 14,California Code of Regulations, § 15064.5): (1) Is associated with events that have made a significant contribution to the broad patterns of California's history and cultural heritage (2) Is associated with the lives of persons important in our past (3) Embodies the distinctive characteristics of a type, period, region, or method of construction, or represents the work of an important creative individual,or possesses high artistic value (4) Has yielded,or may be likely to yield,information important in prehistory or history Additionally, the CRHR consists of resources that are listed automatically and those that must be nominated through an application and public hearing process. The CRHR automatically includes the following(California Public Resources Code§5024.1[d]): • California properties listed on the National Register and those formally Determined Eligible for the NRHP • California Registered Historical Landmarks from No. 770 onward • Those California Points of Historical Interest that have been evaluated by the Office of Historic Preservation and have been recommended to the State Historical Commission for inclusion on the CRHR Other resources that may be nominated to the CRHR include: • Historical resources with a significance rating of Category 3 through 5 (Those properties identified as eligible for listing on the National Register, the CRHR, and/or a local jurisdiction register) • Individual historical resources Rehabilitation of Western Regional Sewers, Project 3-64 3-50 3.4-Cultural Resources • Historical resources contributing to historic districts • Historical resources designated or listed as local landmarks, or designated under any local ordinance,such as a historic preservation overlay zone The fact that a resource is not listed in or determined eligible for listing in the CRHR, or is not included in a local register of historical resources, does not preclude a lead agency from determining that the resource may be a historical resource(Title 14,California Code of Regulations 15064.5[a][4]). CECIA includes in its definition of historical resources "any object [or] site ...that has yielded or may be likely to yield information important in prehistory' (Title 14, California Code of Regulations 15064.5[a][3][D]), which is interpreted to include fossil materials and other paleontological resources. More specifically, destruction of a "unique paleontological resource or site or unique geologic feature" constitutes a significant impact under CEQA(CEQA Guidelines Appendix G). Treatment of paleontological resources under CECIA is generally similar to treatment of archaeological and historical resources, requiring evaluation of resources in the Project area; assessment of potential impacts on significant or unique resources; and development of mitigation measures for potentially significant impacts, which may include monitoring, combined with data recovery excavation and/or avoidance. State of California Public Resources Code The State of California Public Resources Code, Sections 5097 et seq. and 30244, include additional state level requirements for the assessment and management of paleontological resources. These statutes require reasonable mitigation of adverse impacts to paleontological resources resulting from development on state lands and define the excavation, destruction, or removal of paleontological "sites" or "features" from public lands without the express permission of the jurisdictional agency as a misdemeanor. As used in Section 5097, "state lands" refers to lands owned by or under the jurisdiction of the state or any state agency. "Public lands" is defined as lands owned by or under the jurisdiction of the state, or any city, county, district, authority, or public corporation, or any agency thereof(California Public Resources Code,Section 5097.5[b]). In addition, archaeological, paleontological, and historical sites are protected pursuant to the policies and regulations enumerated under the California Public Resources Code as follows: • California Public Resources Code Sections 5020-5029.5 continue the former Historical Landmarks Advisory Committee as the State Historical Resources Commission. The commission oversees the administration of the CRHR and is responsible for the designation of State Historical Landmarks and Historical Points of Interest. • California Public Resources Code Sections 5079-5079.65 define the functions and duties of the Office of Historic Preservation (OHP). The OHP is responsible for the administration of federally Rehabilitation of Western Regional Sewers, Project 3-64 3-51 3.4-Cultural Resources and state mandated historic preservation programs in California and the California Heritage Fund. • California Public Resources Code Sections 5097.9-5097.991 provide protection to Native American historical and cultural resources and sacred sites and identify the powers and duties of the Native American Heritage Commission (NAHC). It also requires notification to descendants of discoveries of Native American human remains and provides for treatment and disposition of human remains and associated grave goods. (See also Section 3.13 Tribal Cultural Resources.) State of California Health and Safety Code The California Health and Safety Code Section 7050.5(b) specifies protocol when human remains are discovered. Specifically, burials or human remains found outside a known cemetery are not to be disturbed or removed unless by authority of law. The area of a discovery of human remains should remain undisturbed until a County coroner is notified and has examined the remains prior to determining the appropriate course of action within two days of notice. The County coroner will notify the Native American Heritage Commission within 24 hours should the remains be found to be those of a Native American. 6alifernia3enate-U, 32 Cali{.....:..

(Please note that the above deleted text was moved to a new section of this Final EIR, Section 3.13 Tribal Cultural Resources.) 3.4.1.3 Local The County of Orange and various municipalities have regulations and guidelines pertaining to the identification and treatment of cultural resources.All local regulations applicable to the Project area are presented here. Orange County The Orange County General Plan (2011) Resources Element contains explicit guidelines for paleontological and cultural resources in the Cultural Resources portion of the document. Additionally, Orange County has paleontological and archaeological certification programs to identify qualified paleontologists for work within the County. Three goals and seven objectives address both paleontological and cultural resources. Cultural Resources Goal 1 requires the County to raise the awareness and appreciation of Orange County's cultural and historic heritage. To achieve this, Objective 1.1 requires that the County facilitate and participate in activities that inform people about the social, cultural, economic, and scientific values of Orange County's heritage. Objective 1.2 requires that the County work through the Orange County Historical Commission in the areas of history, paleontology, archaeology,and historical preservation. Rehabilitation of Western Regional Sewers, Project 3-64 3-53 3.4-Cultural Resources Goal 2 states that the County shall encourage,through a resource management effort,the preservation of the County's cultural and historic heritage. Objective 2.1 states that the County shall promote the preservation and use of buildings, sites, structures, objects, and districts of importance in Orange County through the administration of planning, environmental, and resource management programs. Objective 2.2 requires that the County take all reasonable and proper steps to achieve the preservation of archaeological and paleontological remains or their recovery and analysis to preserve cultural, scientific, and educational values. Objective 2.3 requires that the County take all reasonable and proper steps to achieve the preservation and use of significant historic resources including properties of historic, historic architectural, historic archaeological,and/or historic preservation value. Goal 3 states that the County shall aim to preserve and enhance buildings, structures,objects,sites, and districts of cultural and historic significance. Objective 3.1 requires that the County undertake actions to identify, preserve, and develop unique and significant cultural and historic resources. Objective 3.2 states that the County shall develop and maintain an archive for historically valuable records, thereby promoting knowledge and understanding of the origins, programs, and goals of the County of Orange. The following policies addressing archaeological, paleontological, and historical resources shall be implemented at appropriate stage(s) of planning, coordinated with the processing of a project application, as follows: • Identification of resources shall be completed at the earliest stage of project planning and review such as general plan amendment or zone change. • Evaluation of resources shall be completed at the intermediate stages of project planning and review such as site plan review, subdivision map approval, or at an earlier stage of project review. • Final preservation actions shall be completed at the final stages of project planning and review such as grading,demolition, or at an earlier stage of project review. Additionally, Orange County has a well-defined set of guidelines regarding paleontological resources, their disposition,and distribution throughout the County(Cooper and Eisentraut 2002). City of Anaheim The City of Anaheim approved the Citywide Historic Preservation Plan in May of 2010 with the following goals: (1) Increase the public recognition and awareness of Anaheim's historic resources (2) Provide the means to identify historic resources throughout the City (3) Provide basic design guidelines and technical assistance to property owners to avoid alterations and additions that compromise the characteristic features of a historic structure Rehabilitation of Western Regional Sewers, Project 3-64 3-54 3.4-Cultural Resources (4) Promote the importance of preserving and protecting historic structures as a significant component of the City's physical environment and identity, and as a model for environmental sustainability (5) Provide information for new design and planning that is compatible with its surroundings on a neighborhood level,and that reflects Anaheim's diverse building types and urban patterns (6) Promote the economic health of the City and protect property values by encouraging new construction and investment that is compatible with the scale, style, and character of the City's historic neighborhoods (7) Increase property owners' awareness of the economic benefits of designation and preservation, including enhanced property values, financial resources and incentives, and strategic marketing advantages (8) Avoid demolition,inappropriate alteration,and neglect of Anaheim's historic resources (9) Retain the historic characteristics of streetscapes,street patterns,and landscape features (10) Provide an opportunity for property owners within historic districts to propose more specific or rigorous standards and guidelines for the preservation of their historic neighborhoods The City of Anaheim designates historical resources into three categories of recognition: Historical Districts, Historically Significant Structures, and List of Structures of Historical Interest.As detailed in the Citywide Historic Preservation Plan: Historic Districts are usually contiguous groups of buildings that are best evaluated together due to their common history and physical characteristics that contribute to the significance of the district. Historically Significant Structures are single properties located outside historic districts, where they act as visually identifiable reminders of the City's history and the development of its built environment.The City maintains a List of Structures of Historical Interest to track properties outside existing districts that have been identified by City staff or the public. A historic district is eligible for listing if it meets the following criteria: (1) It is associated with broad patterns of local, regional,or national history (2) It cohesively illustrates the characteristics of a significant architectural style, property type, period, or method of construction; or it represents the work of architects, designers, engineers, or builders who are locally,regionally,or nationally significant Buildings located within a historic district must meet all of the following conditions to be considered contributors to the significance of the district: (1) Constructed within the period of significance documented for the district (2) Associated with the significant historic themes identified for the district (3) Retain historic integrity from the period of significance Rehabilitation of Western Regional Sewers, Project 3-64 3-55 3.4-Cultural Resources A building,structure,or object that is over 50 years old and possesses sufficient historic integrity may be considered for listing as a Historically Significant Structure if it meets one or more of the following criteria: (1) It strongly represents a significant event or broad patterns of local, regional, or national history (2) It is associated with the life of a significant person in local, regional,or national history (3) It is a very good example of a significant architectural style, property type, period, or method of construction; or it represents the work of an architect, designer, engineer, or builder who is locally, regionally,or nationally significant;or it is a significant visual feature of the City A building, structure, or object that meets these criteria may be added to the list of Structures of Historical Interest with the approval of the Executive Director of the City's Community Development Department. City of Buena Park Adopted in 2010, the Buena Park 2035 General Plan considers historic and cultural resources as "resources that are fundamental components of Buena Park's environment" (Buena Park 2010:5-1).The General Plan has no specific criteria applicable to the preservation or treatment of historic resources, but defers to federal and state regulatory guidelines. In general, the City of Buena Park considers "resources greater than 50 years old as having the potential to be a considered a historic resource," and historic resources are generally "associated with a significant historic event or person(s) and/or have a historically significant style, design, or achievement" (Buena Park 2010:5-1). Buena Park recognizes 16 landmarks within its boundaries as having local or regional significance: the Emery Borrow Fossil Pit, Los Coyotes Monument, Dr. D.W. Hasson Home, Whitaker-Jaynes House, Bacon House, Warren Building, William E. Tice House, Stage Stop Hotel, Knott's Berry Farm, Old Maizel and School, George Trapp House, First Congregational Church, Buena Park Women's Club, Lily Creamery Site, Bacon Avocado, and California Pepper Trees. Old Maizel and School is listed as California Historical Landmark No. 729. CM of La Palma Adopted in June of 2014,the City of La Palma General Plan does not have specific criteria or treatment guidelines regarding cultural resources. However, as part of the City's objective (Goal LU-4) of continuing "to encourage and facilitate a mix and diversity of land uses that meet the economic, environmental, educational, and social needs of the City while remaining sensitive to La Palma's small town character," the City has adopted Policy LU-4.9, which states that the City will "encourage the maintenance and preservation of historically, culturally, and/or architecturally significant structures and sites in the community' (City of La Palma 2014:2-57). Rehabilitation of Western Regional Sewers, Project 3-64 3-56 3.4-Cultural Resources City of Los Alamitos Chapter 17.22 of the City of Los Alamitos Municipal Code has specific guidelines applicable to the treatment of cultural resources and landmarks within Los Alamitos. The specific language of the Municipal Code is as follows: "17.22.030 Purpose. 'This section is created to assist in the identification and preservation of historic and cultural resources within the city.These guidelines are necessary in order to preserve those elements of Los Alamitos' heritage,which may now or in the future be endangered as to their very existence or in maintaining their historic or cultural integrity.

Seal Beach recognizes archaeological resources as "the material remains of an area's prehistorical (aboriginal/Native American) or historical (European and Euro-American) human activity. 'Prehistoric'sites date from the time of early human occupation to the arrival of Juan Cabrillo in 1542. 'Historic' sites postdate Cabrillo and include periods of Spanish, Mexican, and American settlement" (City of Seal Beach 2013:CR-1). The primary goal (Goal 1) of the Cultural Resources Element of the General Plan is to preserve and protect historical, archaeological, and paleontological resources (City of Seal Beach 2013:CR-6). The General Plan presents specific policies to attain this goal: "Policy 1: Balance the benefits of development with the project's potential impacts to existing cultural resources. "Policy 2: Identify,designate, and protect sites and buildings of historic importance. "Policy 3: Coordinate cultural resources programs and development project review with affected resource agencies and Native American representatives. [See also Section 3.13 Tribal Cultural Resources.] "Policy 4: Identify funding programs to assist private and public property owners in the Preservation of buildings and sites of historic importance. Rehabilitation of Western Regional Sewers, Project 3-64 3-60 3.4-Cultural Resources "Policy 5: Assess development proposals for potential impacts to significant archaeological resources pursuant Section 15064.5 of the California Environmental Quality Act(CEQA). Require a study conducted by a professional archaeologist for all development proposals located in areas known to be sensitive for cultural resources." To implement these policies,the City has set the following requirements(Seal Beach 2013:CR-7-CR-9): "Protect Significant Paleontological Resources: Assess development proposals for potential impacts to significant paleontological resources pursuant to§15064.5 of the California Environmental Quality Act. If the project involves earthwork, require a study conducted by a professional paleontologist to determine if paleontological assets are present and if the project will significantly impact the resources. If significant impacts are identified, either require the project to be modified to avoid impacting the paleontological materials, or require measures to mitigate the impacts. Development Services is the primary City department responsible for ongoing implementation, and funding is anticipated to be provided by development fees. "Historical,Archaeological and Paleontological Resource Management Guidelines: Prepare and maintain guidelines for historic, archaeological, and paleontological resource management to guide review of development proposals (Presented in Appendix A of the General Plan). These guidelines should be expanded to also address historical and paleontological resource management and also updated periodically to address new technological and legal approaches to cultural resource analysis and management. Development Services is the primary City department responsible for ongoing implementation, and funding is anticipated to be provided by the General Fund and state and federal grants. "Establishment of Programs for Preservation of Historic/Archaeologic/Paleontological Resources: Identify and implement programs to assist and encourage private property owners to preserve historic, archaeologic, and paleontological resources within the City. Development Services is the primary City department responsible for ongoing implementation, and funding is anticipated to be provided by development fees,and state and federal tax credits and grants. "Inventory of Historic and Cultural Landmarks: Establish and update as needed a City Inventory of Historic and Cultural Landmarks using criteria and recording standards consistent with state regulations for use in evaluating development proposals under CEQA. The Development Services Department and the Archaeological Advisory Committee are primarily responsible for ongoing implementation, and funding is anticipated to be provided by the General Fund,state and federal funding programs." Appendix A of the Cultural Resources Element details the procedures and information to help implement the goals and policies of the Cultural Resources Element. Appendix A-1 presents the procedures, which include archaeological research and survey for undeveloped properties within the boundaries of the City of Seal Beach, to be conducted by archaeological consultants appointed by the City Council. Research will include a literature search and review of the Cittrs Baseline Survey and a Rehabilitation of Western Regional Sewers, Project 3-64 3-61 3.4-Cultural Resources records search at the South Central Coastal Information Center at California State University, Fullerton. The research will also include a site survey which will cover 100 percent of the subject site for properties that have not been previously surveyed, or if the records and literature review indicate that cultural resources are known to exist on the site. If a site is discovered as a result of survey, a test phase that includes excavation must be conducted. If the site is not to be preserved in situ, then a final mitigation program must be implemented. Final mitigation may involve capping the site, relocating the resource (if applicable), excavating all or part of the site, or renovating or reconstructing historic or archaeological structures. An Archaeological Advisory Committee, comprising members appointed by the City Council to serve one-year terms, will provide guidance and advice pertaining to the treatment of cultural resources. Per Appendix A-2, all research projects requiring excavation must present a Research Design Document to be approved by the City Council. Per Appendix A-3, all Native American consultants must present documentation verifying tribal affiliation and must have completed a 20-hour course in monitoring methods from an accredited archaeologist or archaeology program prior to appointment. Appendix A-4 requires that all archaeological consultants must comply with the standards set forth by the Register of Professional Archaeologists, regardless of membership. All Principal Investigators must hold a Doctor of Philosophy (Ph.D.) or Master of Arts (M.A.) degree in Anthropology or Archaeology from an accredited college or university; and all Field Directors, Crew Chief, or Research Assistant shall possess at least a Bachelor of Arts (B.A.) degree in Anthropology,Archaeology, or History and have at least two months of relevant accumulated field experience. 3.4.z Existing Conditions 3.4.2.1 Paleontology Geologic mapping by Bedrossian and Roffers (2012) and McCrea and Wanish (2010) indicates that the proposed Project area is underlain by Quaternary (Holocene to late Pleistocene) young alluvial fan deposits (Qyf) and recent artificial fill (af). The geographic distributions of the geologic units in the proposed Project area are illustrated in Figure 3.4-2. A literature review indicates that no fossil resources have been recorded within or in the immediate vicinity of the proposed Project area (McLeod 2015;Jefferson 1991; PBDB 2015; UCMP 2015). Youne Alluvial Fan Deposits My" The young alluvial fan deposits consist of unconsolidated, undissected silt, sand, gravel, cobbles, and boulders laid down during the Holocene to late Pleistocene. Due to their age, these younger deposits typically do not contain significant vertebrate fossils, at least in the uppermost layers. In this area, the younger deposits are underlain by older alluvial deposits, which are known to preserve paleontological resources (McLeod 2015). The young alluvial fan deposits have a low paleontological sensitivity at the surface based on Society of Vertebrate Paleontology(SVP 2010) procedural guidelines. Rehabilitation of Western Regional Sewers, Project 3-64 3-62 3.4-Cultural Resources Artificial Fill(Qvfl Artificial fill is late Holocene(recent) in age and consists of previously disturbed sediment resulting from human activities. It is commonly used in construction projects (e.g., structures, roadways, concrete channels, railway embankments, etc.) (McCrea and Wanish 2010). By their very nature, fossils found in artificial fill have lost their native provenance and therefore have marginal scientific value. The origin of the fossil is unknown when discovered in fill, therefore losing its significance for paleontological resources. Artificial fill, therefore, is generally considered to have no potential to produce significant paleontological resources based on SVP(2010) procedural guidelines`. 3.4.2.2 Cultural History Historical Background A summary of the historical background of the region is provided here to present the cultural content of the proposed Project area. For a more in-depth history of the region, refer to the Cultural Constraints Report in Appendix C(Kay 2015). Humans have lived in the region of southern California for at least 10,000 years and have left remnants of their activities in the form of sites, features, objects, structures, and buildings throughout Orange County. Some of these cultural resources are still present today within or in proximity to the Project area. The Project area encompasses lands that were once inhabited by the Tongva, also known as the Gabrielehos.The Tongva are an Uto-Aztecan (formerly termed "Shoshonean")group that likely entered the Los Angeles Basin as recently as 1500 Before Present(B.P.)from the southern Great Basin or interior California deserts. However, it is also possible that they migrated in successive waves over a longer period of time beginning around 4000 B.P. It has been proposed that the Uto-Aztecan speakers displaced local Hokan occupants of the southern coast (Kroeber 1925:578-580), as Hokan speakers in the area are represented by the Chumash to the north and the Diegueho to the south. Before the arrival of the Spanish, the Tongva lived in an area of more than 1,500 square miles that included the watersheds of the Los Angeles River, San Gabriel River, Santa Ana River, and Rio Hondo, as well as the southern Channel Islands. They established at least 50 residential communities, or villages, with 50 to 150 individuals. Each community consisted of one or more lineages associated with a permanent territory. Each territory was represented by a permanent central settlement with associated hunting,fishing, gathering, and ritual areas. A typical settlement would have had a variety of structures used for daily living, recreation,and rituals. In the larger communities,the layout was characterized by a ritualistic or sacred enclosure that was encircled by the residences of the chief and community leaders, 6 The origin of the fossil is unknown when discovered in fill, therefore losing its scientific value and significance for paleontological resources.Per the SVP definition of significance,fossils in fill would not meet the criteria since they do not have native provenance. Rehabilitation of Western Regional Sewers, Project 3-64 3-63 3.4-Cultural Resources around which were the smaller homes of the rest of the community. Sweathouses, cemeteries, and clearings for dancing and playing were also common at larger settlements(McCawley 1996:32-33). Cultural expressions included beads, baskets, bone and stone tools and weapons, shell ornaments, wooden bowls and paddles, and steatite ornament and cooking vessels (Blackburn 1963). These items were traded frequently, especially with the Chumash, who often exchanged olivella-shell beads as currency for Tongva goods. As with other Native American groups,the settlement of Europeans in California brought many conflicts and diseases to the Tongva as the Spanish sought to claim the lands as their own, and, in the process, incorporated Native American groups into the mission system. Today, the Tongva continue their traditions in southern California with a population of approximately 2,000 individuals. The proposed Project area encompasses multiple cities and communities in Orange County, including Anaheim, Buena Park,Cypress, La Palma, Los Alamitos, Rossmoor, and Seal Beach. Prior to the twentieth century, most of these cities and communities had their roots in agriculture, dairy production, and cattle ranching. They began to accommodate more commercial and residential development during the first half of the twentieth century. The period after World War II saw a boom of residential and commercial development in the region,spurring growth in population,industry,and commerce. 3.4.2.3 Existing Resources A cultural resources records search and survey encompassing areas of both build alternatives was completed.The records searches, conducted at the South Central Coastal Information Center on June 9, 2015 and October 7, 2015, accounted for previous investigations and previously-documented cultural resources within the Project area and a 1/8-mile buffer(Figure 3.4-1). The results of the records search are presented in the Cultural Constraints Report (Appendix Q. In addition, the field surveys of the Project area, conducted on July 25, 2015 and October 5, 2015, resulted in the discovery of the Forest Lawn Memorial Park in Cypress as a historical resource eligible for listing on the National Register of Historic Places and the California Register of Historical Resources. A review of the records at California Historical Resources Information System indicated no historical resources and two archaeological resources in the Project area. Both of these resources are addressed in Section 3.4.4.3. The records search conducted at the South Central Coastal Information Center revealed that two previously documented sites intersect the proposed Project area: P-30-001352 and P-30-001502. These sites still maintain potential for archaeological resources. Site P-30-001352 was described as a secondary marine shell deposit encompassing 10,000 square meters. The southern half of the site was destroyed by the construction of Interstate (1-) 405, and the northern half has since been built over with a parking lot and corporate buildings.As the site's materials were reported to have originated from elsewhere (i.e., introduced) and have been disturbed since, the site has lost integrity and historical context and is not eligible for any historic registers. Rehabilitation of Western Regional Sewers, Project 3-64 3-64 3.4-Cultural Resources Site P-30-001502 was first documented in 1999 as a scatter of prehistoric artifacts. The site is reported to be adjacent to and east of the Seal Beach Blvd. Interceptor alignment along Seal Beach Boulevard, within the United States (U.S.) Naval Weapons Support Facilities, and was reported to have been disturbed by the development of the Orange County Flood Control Channel.The westernmost boundary of the site is within the proposed Project area and was likely disturbed by the construction of the existing road (Seal Beach Boulevard). The last investigation of this site in 2010 by URS archaeologists reported the presence of prehistoric archaeological materials in areas that had not been disturbed. These areas are outside the proposed Project area. The field survey resulted in the discovery of one historical resource within the proposed Project area. The resource is the nearly 150-acre Forest Lawn Memorial Park (Forest Lawn) cemetery located at 4471 Lincoln Avenue in Cypress. This cemetery had not been formally documented as a historical resource and therefore had not been recommended for eligibility for listing on the National Register of Historic Places or the California Register of Historical Resources prior to the survey carried out for this Project. Historical research indicates that the cemetery appears to have been built as early as 1958, with key buildings completed by 1961. Forest Lawn was opened to the public in 1964. Forest Lawn qualifies as a significant historical resource because it meets several eligibility criteria of the NRHP and the CRHR. Namely, the resource is 50 years old or older; possesses integrity of location, design, setting, materials, workmanship, feeling, and association; and meets Criterion C of the NRHP and Criterion 3 of the CRHR (Embodies the distinctive characteristics of a type, period, region, or method of construction, or represents the work of an important creative individual, or possesses high artistic value) (Kay 2015:29). The individual elements that contribute to the resource's significance and eligibility include the Ascension Mausoleum, the Church of Our Fathers, the mortuary building and its associated facilities, and the maintenance building, all of which comprise the original buildings of the Memorial Park. Any agency, organization, individual, or other entity can nominate a resource to the CRHR through the Nomination Packet,along with the California Department of Parks and Recreation Form 523 (completed for this study).The local government in whose jurisdiction the resource is located should be notified by certified mail that an application will be filed with the State Historic Preservation Officer(SHPO)and that the local government should provide written comments within 90 days. The application and comments are to be submitted to the SHPO for review,and a determination is made in regard to the site's eligibility on the CRHR. For nomination to the NRHP,the process includes additional applications submitted to the National Park Service, initiating a process that requires the same process of review, notification to property owners and local governments, and public review and comments. The process is undertaken through the SHPO.The application is submitted by the state to the National Park Service in Washington, D.C. for final review and, if approved, listing by the Keeper of the NRHP. The National Park Service makes a listing decision on the NRHP within 45 days. The proposed Project alignment for the Los Alamitos Sub-trunk along Guardian Drive is immediately adjacent to several hundred interment markers or memorial tablets. The memorial tablets on the east side of Guardian Drive, located in an area called 'The Sheltering Trees;' are less than 2 feet from the Rehabilitation of Western Regional Sewers, Project 3-64 3-65 3.4-Cultural Resources Project area; and their orientation indicates that the interments are parallel to the Project area. The tablets on the west side, located in the "Garden of Protection," are less than 7 feet away from the Project area and appear to be perpendicular to the Project area. 3.4.3 Thresholds of Significance The following significance criteria are based on Appendix G of the CEQA Guidelines (14 California Code of Regulations 15000 et seq.) and are used to evaluate the potential for significant project impacts related to cultural resources'. Project impacts on cultural resources would be significant if the proposed Project would: CUL-1: Cause a substantial adverse change in the significance of a historical resource as defined in Section 15064.5 CUL-2: Cause a substantial adverse change in the significance of an archaeological resource pursuant to Section 15064.5 CUL-3: Directly or indirectly destroy a unique paleontological resource or site or unique geologic feature CUL-4: Disturb any human remains, including those interred outside of fermal dedicated cemeteries 3.4.4 Impact Analysis CUL-1: Cause a substantial adverse change in the significance of a historical resource as defined in Section 15064.5? 3.4.4•1 Construction Impacts Common Build Alternative Element Impacts Both Build Alternatives 1 and 2 would entail rehabilitation or replacement of the Westside Pump Station force main and wet well, as well as installation of an air scrubber or air jumper line for odor control. In addition, both build alternatives would entail rehabilitation of the Orange-Western Sub-trunk and Seal Beach Blvd. Interceptor pipelines using trenchless cured-in-place pipe (CIPP) methods. Further, portions ' Please note: Since the publication and circulation of the IS/NOP, recently adopted legislative amendments to the CEQA Checklist have created a separate Tribal Cultural Resource impact category. The significance question contained in the revised checklist is, "Have California Native American tribes traditionally and culturally affiliated with the project area requested consultation pursuant to Public Resources Code section 21080.3.1?If so,has consultation begun?"As discussed in Section 3.4.4.3 Construction Impacts,consultation with Native American Tribes has been initiated(See Appendix A)and, to date,two tribes have expressed interest in the Project. OCSD would provide for the presence of a TF hal tribal on-site monitor in response to AB S2 consultations.Thus,the gresenE Draft EIR meets the letter and intent of the amended CEQA Checklist. Rehabilitation of Western Regional Sewers, Project 3-64 3-66 3.4-Cultural Resources of the existing Westside Relief Interceptor sewer pipe would be rehabilitated in place using trenchless CIPP methods under both build alternatives. Manholes associated with these pipelines would be replaced or rehabilitated, as appropriate. The cultural resources survey of the proposed Project identified that an approximately 0.5-mile portion of the Los Alamitos Sub-trunk weu�may require open-cut replacement within the Forest Lawn Memorial Park cemetery in the City of Cypress, should either build alternative be adopted. While the proposed Project would be undertaken within the boundaries of the Forest Lawn Memorial Park, replacement of the Los Alamitos Sub-trunk within OCSD easement and Guardian Drive would not affect any of the individual elements that contribute to the resource's significance and eligibility. Forest Lawn historical elements include the Ascension Mausoleum,the Church of Our Fathers,the mortuary building and its associated facilities,and the maintenance building, all of which comprise the original buildings of the Memorial Park. The Project under either build alternative would intersect the Forest Lawn Memorial Park in Cypress but would have a less than significant impact on the historical resources at Forest Lawn with implementation of mitigation measures CUL MM 3, CUL MM 4, CUL MM 5, and CUL MM 6, as outlined in the Cultural Constraints Report (Appendix C)and in Section 3.4.5, based on the results of the records search and field survey. Build Alternative 1 Build Alternative 1 is located within paved public rights-of-ways within city streets or OCSD easements. A cultural resources records search and survey encompassing areas of both build alternatives was completed (see Figure 3.4-1). A review of the records at California Historical Resources Information System indicated no historical resources, other than Forest Lawn described above, and two archaeological resources in the Project area. Both of these archaeological resources are addressed in Section 3.4.4.3. As described under the Common Build Alternative Element Impacts above, Build Alternative 1 would have a less than significant impact on the historical resources at Forest Lawn with implementation of mitigation measures CUL MM 3,CUL MM 4,CUL MM 5,and CUL MM 6,as outlined in the Cultural Constraints Report (Appendix C)and in Section 3.4.5,based on the results of the records search and field survey. Build Alternative 2 Build Alternative 2 was developed after the records search for Build Alternative 1 was completed. Because the horizontal extent of Alternative 2 is anticipated to be the same as Alternative 1, the results of the records search and the field survey remain applicable to the proposed specifications of Build Alternative 2. A review of the records at California Historical Resources Information System indicated no historical resources,other than Forest Lawn described above,and two archaeological resources within the Project area. Both of these archaeological resources are addressed in Section 3.4.4.3. Rehabilitation of Western Regional Sewers, Project 3-64 3-67 3.4-Cultural Resources As described under the Common Build Alternative Element Impacts above, Build Alternative 2 would have a less than significant impact on the historical resources at Forest Lawn with implementation of mitigation measures CUL MM 3, CUL MM 4,CUL MM 5,and CUL MM 6,as outlined in the Cultural Constraints Report (Appendix C)and in Section 3.4.5,based on the results of the records search and field survey.

The proposed Project would have no operational impacts to a historic resource as defined in Section 15064.5 of the California Code of Regulations. CUL-2: Cause a substantial adverse change in the significance of an archaeological resource pursuant to Section 15064.5; 3.4.4.3 Constmctionlmpacts Common Build Alternative Element Impacts Both Build Alternatives 1 and 2 would entail rehabilitation or replacement of the Westside Pump Station force main and wet well, as well as installation of an air scrubber or air jumper line for odor control. In addition, both build alternatives would entail rehabilitation of the Orange-Western Sub-trunk and the Seal Beach Blvd. Interceptor pipelines using trenchless CIPP methods. Further, under both build alternatives, portions of the existing Westside Relief Interceptor sewer pipe would be rehabilitated in place using trenchless CIPP methods. Manholes associated with these pipelines would be replaced or rehabilitated, as appropriate. The records search conducted for the proposed Project indicated that the proposed alignment falls within,or adjacent to,two previously disturbed archaeological sites: P-30-001352 and P-30-001502.Site P-30-001352 was destroyed by the construction of I-405, and the western portion of P-30-001502 was destroyed by the construction of Seal Beach Boulevard and the Orange County Flood Control Channel. The remaining portions of P-30-001502 are on inaccessible property owned by the United States Navy and would not be impacted by the Projects construction activities. Furthermore,the field survey did not identify any archaeological resources within the Project area. Therefore, the impacts of these common build alternative elements are less than significant in those areas where archaeological resources have been identified. Nevertheless, as the Project calls for open-cut trenching down to depths of up to 18 feet bgs along portions of the Project alignment, the possibility remains that archaeological resources that have yet to be identified or documented may be encountered. The results of the records searches and surveys are based on resources that were exposed on or near the surface; but this does not exclude the possibility of subsurface deposits at lower depths, particularly in areas comprising native or undisturbed soils. In this situation, the potential to adversely impact undiscovered cultural resources is unknown but potentially significant; however, implementation of CUL MM 1,CUL MM 7, and CUL MM 8 would reduce these potential impacts to less than significant. Rehabilitation of Western Regional Sewers, Project 3-64 3-70 3.4-Cultural Resources Build Alternative 1 Build Alternative 1 would replace portions of the existing Los Alamitos Sub-trunk and the Westside Relief Interceptor with new, larger capacity pipe. This build alternative also would rehabilitate portions of the existing Los Alamitos Sub-trunk and the Westside Relief Interceptor sewer pipe in place. In addition. Build Alternative 1 would rehabilitate the Orange-Western Sub-trunk and the Seal Beach Blvd. Interceptor pipelines in place. Build Alternative 1 is located within paved public easements within city streets or OCSD easements. As such,the proposed improvements are expected to affect only areas that have been previously disturbed. The records search conducted for the proposed Project indicated that the proposed alignment falls within, or adjacent to,two previously disturbed archaeological sites: P-30- 001352 and P-30-001502. P-30-001352 was destroyed by the construction of 1-405, and the western portion of P-30-001502 was destroyed by the construction of Seal Beach Boulevard and the Orange County Flood Control Channel. The remaining portions of P-30-001502 are on inaccessible property owned by the United States Navy and would not be impacted by the Project's construction activities. Furthermore,the field survey did not identify any archaeological resources within the Project area. The documented disturbance and developed infrastructure through these sites or anywhere else within the proposed Project area do not preclude the potential for the presence of archaeological deposits. While the proposed Project is not expected to disturb these deposits,excavation in the proposed Project area could displace previously undisturbed soils containing archaeological materials, which will result in a significant impact. In this situation, the potential to adversely impact undiscovered cultural resources is unknown but potentially significant; however, implementation of CUL MM 1,CUL MM 7, and CUL MM 8 would reduce these potential impacts to less than significant(see Section 3.4.5 Mitigation Measures). Consultation with Native American Tribes has been initiated (Ssee Section 3.13 Tribal Cultural Resources Ind Appendix A), and those that have expressed an interest in this Project will continue to be apprised of Project activities and changes as the construction phase nears. To date, the status of Tribal consultation is: Gabrielefio Band of Mission Indians-Kiz Nation.On July 15, 2015, in accordance with AB 52,the Gabrielefio Band of Mission Indians-Kiz Nation (Gabrielefio)notified OCSD of their interest in the District's proposed projects. OCSD responded to this request on August 25, 2015, and provided a brief description of various projects and maps. On December 15, 2015, the Gabrielen"o responded to OCSD with a request to be consulted about one of the projects — the Rehabilitation of Western Regional Sewers, Project No. 3-64, which is the subject of this Environmental Impact Report (EIR) — and requested to have one of the Tribe's certified Native American monitors on site during ground-disturbing activities. OCSD replied to this request on February 11, 2016, providing additional project-specific information, advising the Tribe that the construction phases are not expected to begin until the year 2019, and inviting the Tribe to a meeting or further correspondence by phone or email, as desired. As of May 6, 2016, the Gabrielefio have not responded; however,the Tribe will continue to be updated on this project Rehabilitation of Western Regional Sewers, Project 3-64 3-71 3.4-Cultural Resources and the specifics on which sections of the alignment will require monitoring based on the engineering design. • Juanefio Band of Mission Indians. In accordance with AB 52, the Juaneno Band of Mission Indians (Juaneno) notified OCSD of their interest in the District's proposed projects on August 15, 2015. OCSD responded to this request on August 25, 2015, and provided a brief description of various projects and maps. No response was received within 30 days; however,on February 11, 2016, a second letter was sent to the Juanefio to ensure that the first letter was received and to ask again about their interest in any of the OCSD's projects. On March 9, 2016, the Juaneno replied to OCSD by phone and requested to have one of their monitors present during ground-disturbing activities along the Seal Beach Boulevard segment of the alignment. The Juaneno will continue to be updated on this project and the timing of monitoring for the Seal Beach Boulevard segment of the pipeline. • Native American Heritage Commission. On December 13, 2015, PSI, on behalf of the OCSD, contacted the Native American Heritage Commission (NAHC) for a search of their Sacred Lands File for Project No. 3-64's area of potential effects. The NAHC responded on January 13, 2016, indicating that no sites were identified within the area of potential effects for Project No. 3-64. No further consultation with the NAHC is required. Build Alternative 1 is anticipated to have a less than significant potential impact to archaeological resources as defined in Section 15064.5 of the California Code of Regulations. Based on the results of the records search,the Project would not intersect any previously recorded resources. Furthermore,the field survey resulted in no discovery of archaeological resources. However, as the Project calls for open- cut trenching down to depths of up to 18 feet bgs along portions of the Project alignment,the possibility remains that cultural resources that have yet to be identified or documented may be encountered.

In this situation, the potential to adversely impact undiscovered cultural resources is unknown but potentially significant; however, implementation of CUL MM 1, CUL MM 7, and CUL MM 8 would reduce these potential impacts to less than significant (see Section 3.4.5). Build Alternative 2 Build Alternative 2 would replace the entire Los Alamitos Sub-trunk Pipeline with new, larger capacity Pipe. This build alternative also would divert all flow from the Westside Relief Interceptor north of Orange Avenue to an enlarged Los Alamitos Sub-trunk via a new diversion structure. Build Alternative 2 would rehabilitate the entire length of the Western Relief Interceptor, as well as the Orange-Western Sub-trunk and the Seal Beach Blvd. Interceptor pipelines, in place using CIPP methods.

The alignment of the Los Alamitos Sub-trunk pipeline,currently 34,620 feet long,would be increased to accommodate flows from the Westside Relief Interceptor through a new diversion structure at Denni Street and Orange Avenue. In addition, the current pipe diameters of the alignment, 18 inches to 30 inches, would be increased to diameters of 21 inches to 39 inches.The new pipeline would require trenching and open-cut construction to a depth up to 18 feet bgs along the entire Los Alamitos Sub-trunk street alignment.

Operation of the proposed Project would not involve excavation within previously undisturbed soils. The proposed Project would result in no operational impacts to archaeological resources as defined in Section 15064.5, and no mitigation is required. CUL-3; Directly or indirectly destroy a unique paleontological resource on site or unique geologic feature? 3.4.4.5 Constructionlmpacts Common Build Alternative Element Impacts Both Build Alternatives 1 and 2 would entail rehabilitation or replacement of the Westside Pump Station force main and wet well, as well as installation of an air scrubber or air jumper line for odor control. In Rehabilitation of Western Regional Sewers, Project 3-64 3-73 3.4-Cultural Resources addition, both build alternatives would entail rehabilitation of the Orange-Western Sub-trunk and the Seal Beach Blvd. Interceptor pipelines using trenchless CIPP methods. Further, under both build alternatives, portions of the existing Westside Relief Interceptor sewer pipe would be rehabilitated in place using trenchless CIPP methods. Manholes associated with these pipelines would be replaced or rehabilitated as appropriate. Anticipated potential impacts to paleontological resources as a result of the construction of these common build alternative elements are less than significant in those areas where such resources have been identified because the proposed improvements would primarily impact areas that have already been disturbed. Additionally, the young alluvial fan deposits and artificial fill that are mapped at the surface of the proposed Project area have low paleontological potential(Figure 3.4-2). Nevertheless, the discovery of paleontological resources during ground-disturbing activities cannot be discounted entirely, particularly during open-cut excavation within previously undisturbed soils along the Los Alamitos Sub-trunk and the Westside Relief Interceptor. Excavation within previously undisturbed soils and inadvertent discovery and/or disposal of paleontological resources is considered a significant impact. In this situation, the potential to adversely impact undiscovered paleontological resources is unknown but potentially significant; however, implementation of CUL MM 2 and CUL MM 7 would reduce these potential impacts to less than significant(see Section 3.4.5 Mitigation Measures). Build Alternative 1 The proposed Project is located primarily within paved public rights-of-way within city streets or OCSD easements and adjacent to existing pipelines.As such,the proposed improvements would primarily impact areas that already have been disturbed. Additionally, the young alluvial fan deposits and artificial fill that are mapped at the surface of the proposed Project area have low paleontological potential(Figure 3.4-2). Nevertheless, the discovery of paleontological resources during ground-disturbing activities cannot be discounted entirely, particularly during open-cut excavation within previously undisturbed soils along the Los Alamitos Sub-trunk and the Westside Relief Interceptor. Excavation within previously undisturbed soils and inadvertent discovery and/or disposal of paleontological resources is considered a significant impact. In this situation, the potential to adversely impact undiscovered paleontological resources is unknown but potentially significant; however, implementation of CUL MM 2 and CUL MM 7 would reduce these potential impacts to less than significant(see Section 3.4.5 Mitigation Measures). Build Alternative 2 Under Build Alternative 2, the general alignment of the proposed Project would remain unchanged, and the results of the analysis for paleontological resources would not be affected. The results provided in Appendix C—Cultural Resources Constraints Report for paleontology accounted for previous investigations within the Project alignment. Because the horizontal extent of the Project is anticipated to be the same as that of the original Project design, the results remain applicable to the proposed specifications of Build Alternative 2. As a result, the Project would not result in construction-related impacts to paleontological resources under Build Alternative 2.The proposed improvements would primarily impact areas that have Rehabilitation of Western Regional Sewers, Project 3-64 3-74 3.4-Cultural Resources already been disturbed. Additionally, the young alluvial fan deposits and artificial fill that are mapped at the surface of the proposed Project area have low paleontological potential(Figure 3.4-2).

Rehabilitation of Western Regional Sewers, Project 3-64 3-76 3.4-Cultural Resources 3.4.4.6 Operatiorallmpacts Operations would consist of ongoing activities related to operation and maintenance of the Western Regional Sewer lines and the Westside Pump Station including completing routine maintenance; cleaning sewer lines and manholes; performing visual inspections utilizing closed-circuit television and camera inspection; and conducting flow-monitoring, as-needed repairs, and chemical dosing for odor and corrosion control.Operation of the proposed Project would not involve excavation within previously undisturbed soils. Operation of the proposed Project would not result in operational impacts to paleontological resources. CUL4: Disturb any human remains, including those interred outside of formal dedicated ferrwel cemeteries? 3.4.4.7 Construction Impacts Common Build Alternative Element Impacts Both Build Alternatives 1 and 2 would entail rehabilitation or replacement of the Westside Pump Station force main and wet well as well as installation of an air scrubber or air jumper line for odor control. In addition, both build alternatives would entail rehabilitation of the Orange-Western Sub-trunk and the Seal Beach Blvd. Interceptor pipelines using trenchless CIPP methods. Further, under both build alternatives, portions of the existing Westside Relief Interceptor sewer pipe would be rehabilitated in place using trenchless CIPP methods. Manholes associated with these pipelines would be replaced or rehabilitated, as appropriate. A portion of the proposed Project area is located in the Forest Lawn Memorial Cemetery.The proximity of existing interments immediately adjacent to the Project area within the cemetery grounds, some located within 2 feet of the proposed Project area, may result in the disturbance of these interments, and therefore, potentially result in significant impact to human remains. However, because the pipeline alignment would remain within existing OCSD easement within Guardian Drive or other locations approved by Forest Lawn Cemetery, disturbance (damage, exposure, impact) to known interments is unlikely. The proposed construction also involves excavation into native soils (soils that have not been previously exposed)outside the cemetery. Although unlikely, there is the potential for unforeseen disturbance of human remains within the cemetery property that have not been formally interred with the Forest Lawn Memorial Park (i.e., burials predating the establishment of Forest Lawn), and the Project would have potentially significant impact on such resources. Excavation within previously undisturbed soils within Forest Lawn Cemetery would be a significant impact, and mitigation measures would be required (see Section 3.4.5 Mitigation Measures). Unforeseen disturbance of human remains potentially outside the cemetery is addressed by the environmental control measures (ECMs) delineated in Table 2.10-1. Therefore, the potential to encounter interred human remains during construction of these common build alternative elements is Rehabilitation of Western Regional Sewers, Project 3-64 3-77 3.4-Cultural Resources less than significant with application of mitigation measures CUL MM 1, CUL MM 4, CUL MM 5, CUL MM 6,CUL MM 7,and CUL MM 8. Build Alternative 1 A portion of the proposed Project area is located in the Forest Lawn Memorial Cemetery.The proximity to existing interments immediately adjacent to the Project area within the cemetery grounds, some located within 2 feet of the proposed Project area, may result in the disturbance of these interments, resulting in potentially significant impact. However, because the pipeline alignment would remain within existing OCSD easement within Guardian Drive or other locations approved by Forest Lawn Cemetery, disturbance (e.g., damage, exposure, impact, or displacement) of known interments is unlikely. The proposed construction may also involve excavation into native soils (soils that have not been previously exposed) within the Project area.Although unlikely,there is the potential for unforeseen disturbance of human remains. Excavation within previously undisturbed soils within Forest Lawn Cemetery would be a significant impact, and mitigation measures would be required (see Section 3.4.5 Mitigation Measures). Unforeseen disturbance of potential human remains outside the cemetery,or disturbance of previously unknown human remains within cemetery property that predate the establishment of the Forest Lawn Memorial Park, is addressed by the ECMs delineated in Table 2.10-1 and would be less than significant with implementation of mitigation measures CUL MM 1, CUL MM 4, CUL MM 5, CUL MM 6, CUL MM 7, and CUL MM 8. Build Alternative 2 Under Build Alternative 2, the proposed Project area is identical to that under Build Alternative 1. Although unlikely, there is the potential for unforeseen disturbance of human remains, resulting in potentially significant impact on burials or human remains. In addition, excavation within previously undisturbed soils within the Forest Lawn Cemetery would be a potentially significant impact; and mitigation measures would be required (see Section 3.4.5 Mitigation Measures). As a result, the potential for construction-related impacts to interred human remains under Build Alternative 2 is identical to that of Build Alternative 1 and, therefore, is less than significant with implementation of mitigation measures CUL MM 1,CUL MM 4, CUL MM 5,CUL MM 6,CUL MM 7,and CUL MM 8. 3.4.4.8 Operational Impacts Operations under both Build Alternative 1 and Build Alternative 2 would consist of ongoing activities related to operation and maintenance of the Western Regional Sewer lines and the Westside Pump Station, including completing routine maintenance; cleaning sewer lines and manholes; performing visual inspections utilizing closed-circuit television and camera inspection; and conducting flow- monitoring, as-needed repairs, and chemical dosing for odor and corrosion control. Operation of the proposed Project would not involve excavation within previously undisturbed soils. Operation of the proposed Project would not result in operational impacts to human remains. Rehabilitation of Western Regional Sewers, Project 3-64 3-78 3.4-Cultural Resources 3.4.4.9 No BuildAlteraative Under the No Build Alternative, there would be no rehabilitation or replacement of the Western Regional Sewers or improvements at the Westside Pump Station other than operations and maintenance activities as discussed in Section 2.6. The No Build Alternative would not impact the significance of a historical or archaeological resource. The No Build Alternative would not impact paleontological resources or disturb human remains. 3.4.5 Mitigation Measures CUL MM 1: OCSD shall retain an archaeologist (Project Archaeologist) meeting the Secretary of the Interior's Standards for Professional Qualified Staff (PQS) to provide worker awareness training regarding archaeological resources to construction personnel prior to the start of construction.The training shall include,at minimum,the following: The types of artifacts, features, or structures that could occur at the proposed Project site The procedures that should be taken in the event of an archaeological discovery, including human remains • Laws protecting archaeological resources and burials • Penalties for destroying or removing archaeological resources, protected historical structures,or burials CUL MM 2: A qualified professional paleontologist, meeting the professional standards enumerated in Cooper et al 2010, shall provide worker awareness training on paleontological resources to construction personnel prior to the start of construction. The training shall include,at minimum,the following: • The types of fossils that could occur at the proposed Project site • The procedures that should be taken in the event of a fossil discovery • Laws protecting paleontological resources • Penalties for destroying or removing paleontological resources CUL MM 3: Final design of the Los Alamitos Sub-trunk within Forest Lawn shall avoid disturbance of historic buildings, structures, or objects on the Forest Lawn property that are outside the OCSD easements. These include the Ascension Mausoleum; the Church of Our Fathers; the Main Mortuary Building;the park's maintenance facilities building; and the park entrance, memorial tablets,grave markers,stones,statues,and ornaments. CUL MM 4: OCSD shall work with Forest Lawn Cemetery to ensure that pipeline alignment will remain within existing OCSD easement, Guardian Drive, or other locations to avoid Rehabilitation of Western Regional Sewers, Project 3-64 3-79 3.4-Cultural Resources disturbance of existing interments immediately adjacent to the alignment. Pipe realignment shall be coordinated with Forest Lawn Cemetery management prior to implementation. Alignments within existing easements will not require Forest Lawn approval, but Project managers shall coordinate with Forest Lawn managers regarding Project details within Forest Lawn property. CUL MM 5: For the portion of the Los Alamitos Sub-trunk within Forest Lawn Cemetery, the contractor shall avoid disturbance of interment ceremonies and gravesites through the use of protective barriers, visual aids (i.e., signs, flagging, etc.) and defined exclusion areas on plans to provide mutually acceptable distance between construction areas and interments, as determined in consultation with Forest Lawn Cemetery management. Visual aids shall distinguish ornamental or structural elements from locations of known gravesites. CUL MM 6: OCSD shall provide a liaison during construction of the Los Alamitos Sub-trunk within Forest Lawn Cemetery. Although disturbance to existing gravesites is not anticipated, should graves be impacted by construction, the OCSD liaison shall take immediate action to notify Forest Lawn and prevent further disturbance. The liaison will notify project managers and the Forest Lawn management should graves be disturbed. The Project managers shall consult with Forest Lawn management to determine the appropriate course of action in the event that impacts to gravesites are anticipated or, if they occur, in order to avoid any further disturbance. CULMM7: In the event of unanticipated archaeological, tribal, or paleontological resource discoveries during construction activities, the contractor shall stop work within 50 feet of the discovery until it can be evaluated by a qualified archaeologist meeting the Secretary of the Interior's Standards for Professional Qualified Staff (PQS) or a paleontologist meeting the professional standards enumerated in Cooper et al 2010. Construction activities may continue in other areas of the site. The qualified archaeologist or paleontologist shall evaluate the resource(s) encountered and recommend appropriate disposition of the resource(s) in consultation with the Orange County Sanitation District. CUL MM 8: Should any tribal entity identified on the Native American Heritage Commission contact list request on-site monitoring during construction of particular segments of the Project area out of concern for potential impacts to known or unanticipated tribal resources, OCSD shall provide a tribal approved Native American monitor/liaison'. Sections of the ' Two such tribes have requested the presence of an on-site monitor for the proposed Project in response to AB 52 consultations with OCSD(See Appendix A). Rehabilitation of Western Regional Sewers, Project 3-64 3-80 3.4-Cultural Resources Project area that may require such monitoring are contingent upon engineering design specifics which have yet to be finalized. 3.4.6 Level of Significance after Mitigation The proposed Project would have less than significant impacts to historical, archaeological, and paleontological resources.A segment of the Project area is in the Forest Lawn Cemetery and would have potentially significant impact to human remains and previously undisturbed areas. Mitigation measures are necessary to reduce such impacts to less than significant levels. Therefore, implementation of CUL MM 1 through CUL MM 8 would render potential impacts on historical, archaeological, and paleontological resources to the level of less than significant. In addition, the implementation of these mitigation measures would reduce impact to burials and human remains from potentially significant to less than significant with mitigation. Rehabilitation of Western Regional Sewers, Project 3-64 3-81 3.5-Geology and Soils 3.5 Geology and Soils This section provides an overview of seismic hazards, landslide hazards, soil erosion potential, and potential impacts to the proposed Project area from liquefaction, unstable soils,and expansive soils. 3.5.1 Regulatory Setting 3.5.1a Federal Earthquake Hazards Reduction Act The Earthquake Hazards Reduction Act of 1977, as amended by Public Laws 101-614, 105-47, 106-503, and 108-360, created the framework for research into the seismic safety of buildings and structures.The purpose of this Act, as amended, is to reduce the risks to life and property from future earthquakes in the United States through the establishment and maintenance of an effective earthquake hazards reduction program. With the Act, Congress established the National Earthquake Hazards Reduction Program (NEHRP).The four primary NEHRP agencies that contribute to earthquake mitigation efforts are the Federal Emergency Management Agency (FEMA), the National Institute of Standards and Technology,the National Science Foundation, and the United States(U.S.) Geological Survey(USGS). The proposed Project area lies within seismically active areas and, as such, is subject to the Act, which requires federal preparedness and mitigation activities including the "development and promulgation of specifications, building standards, design criteria, and construction practices to achieve appropriate earthquake resistance for new structures." Executive Order 12699 Executive Order (EO) 12699 requires an examination of alternative provisions and requirements for reducing earthquake hazards at buildings owned or leased by the federal government and those buildings with federally financed construction, grants, loans, loan guarantees, insurance programs, and licenses (42 United States Code [U.S.C.] 7704(f)(3, 4)) and the incorporation of seismic safety requirements into new building construction. The purpose of these requirements is to reduce risks to the lives of occupants of buildings owned by the federal government and to persons who would be affected by the failures of federal buildings in earthquakes,to improve the capability of essential federal buildings to function during or after an earthquake, and to reduce earthquake losses of public buildings, all in a cost-effective manner. A building means any structure, fully or partially enclosed, used or intended for sheltering persons or property. International Buildine Code The International Building Code (IBC) is a model building code developed by the International Code Council that provides the basis for the California Building Code (CBC). The purpose of the IBC is to provide minimum standards for building construction to ensure public safety, health,and welfare. Rehabilitation of Western Regional Sewers, Project 3-64 3-82 3.5-Geology and Soils Occupational Safety and Health Administration Regulations The Occupational Safety and Health Administration (OSHA) Excavation and Trenching standard, Title 29 of the Code of Federal Regulations, Part 1926.650, covers the requirements for excavation and trenching operations.OSHA requires that all excavations in which employees could potentially be exposed to cave- ins be protected by sloping or benching the sides of the excavation, supporting the sides of the excavation,or placing a shield between the side of the excavation and the work area. 3.5•1•2 State California Geological Survey:Alquist-Priolo Earthquake Fault Zonine Act The Alquist-Priolo Earthquake Fault Zoning Act was passed in 1972 to mitigate the hazard of surface faulting to homes, commercial buildings, and other structures and to prevent the construction of buildings used for human occupancy on active faults with a hazard of surface fault rupture. The State of California and County of Orange Building Codes provide standards and requirements for buildings and structures in order to address the potentially damaging effects of surface fault rupture. The most stringent standards and requirements are applied within Alquist-Priolo Earthquake Fault Zones where faults are known to have ruptured in the past 11,000 years(Holocene time). California Geological Survey:Seismic Hazards Mapping Act The Seismic Hazards Mapping Act was passed in 1990 to mitigate other hazards associated with earthquake faults,meaning non-surface fault rupture earthquake hazards.Among other things, "It is the intent of the State Legislature to provide statewide seismic hazard mapping and a technical advisory program to assist cities and counties in fulfilling their responsibilities for protecting the public health and safety from the effects of strong ground shaking, liquefaction, landslides, or other ground failure, and other seismic hazards caused by earthquakes' (California Public Resources Code§2692(a)). Under the Seismic Hazards Mapping Act, seismic hazard zones must be identified and mapped in order for cities and counties to adequately prepare the safety element of their general plans and to encourage land use management policies and regulations to mitigate hazards to life and property posed by earthquake-triggered ground failures.The California Division of Mines and Geology gathers information from the earthquake fault zones mapping program,the landslide hazard identification program, and the inundation maps. Provisions under this law require that a qualified geologist and civil engineer prepare a geotechnical report for each new construction site to evaluate and assess the geologic hazards that may be present. The city and/or county in which a project is located is responsible for reviewing and approving any such report prior to the commencement of construction (California Department of Conservation, California Geological Survey 1991). Rehabilitation of Western Regional Sewers, Project 3-64 3-83 3.5-Geology and Soils California Building Standards Commission:California Building Code The proposed Project is subject to the applicable sections of the CBC, which is administered by the California Building Standards Commission, Department of Building Safety. The building departments of each city (or the county for unincorporated areas within Orange County) are responsible for ensuring that CBC requirements are met, including provisions for soil and foundation investigations in order to evaluate the presence of critically expansive soils or other soil problems which, if not corrected, could lead to structural defects. 3.5.1.3 Local OCSD Design and Construction Requirements for Sanitary Sewers "Prior to the construction of any facilities for Orange County Sanitation District (OCSD) (or facilities to become the property of OCSD), construction drawings for the subject Work shall be subject to approval by the Resident Engineer and shall be stamped and signed by the Design Engineer preparing the Plans. Approval by the Resident Engineer on drawings for facilities to become the property of OCSD apply only to general design concepts with respect to OCSD's master planned capacity, maintenance procedures, and quality materials" (OCSD 2012, Section 12.2.5 Plan Checking,Approvals and Fees). OCSD Sewer System Management Plan OCSD is required to comply with State Water Control Resources Board (SWRCB) Order No. 2006-0003- DWgadopted May 2,2006,titled "Statewide General Waste Discharge Requirements for Sanitary Sewer Systems." The purpose of the Order is to prevent sewer overflow or spills by establishing a statewide monitoring and reporting program and requiring each local or regional sewer agency to create and implement its own sewer system management plan. The goal is to provide a plan and schedule to properly manage, operate, and maintain all parts of the OCSD sanitary sewer system to prevent and mitigate any sewer overflows(OCSD 2014). City of Seal Beach General Plan The City of Seal Beach General Plan Safety Element (2003) provides a guide to identify and understand potential hazards facing the City of Seal Beach.The Safety Element evaluates hazards that could present a danger to the public through the establishment of goals and policies intended to reduce their impacts. Geologic hazards affecting the City are direct, construction-related, and indirect effects that occur only during earthquakes. The most hazardous impacts are those related to and triggered by seismic events, such as ground shaking and liquefaction. City of Los Alamitos General Plan The City of Los Alamitos General Plan (2015)establishes a comprehensive framework through which the City manages its growth and development to ensure it efficiently and effectively provides public facilities and services. The Public Facilities and Safety Element provides a guide to identify and understand potential hazards to the City of Los Alamitos. This element evaluates hazards that could present a Rehabilitation of Western Regional Sewers, Project 3-64 3-84 3.5-Geology and Soils danger to the public through the establishment of goals and policies intended to reduce their potential occurrence. These hazards include flooding, surface rupture and ground shaking, landslides, seiches, infrastructure hazards, and earthquakes. While no known active or potentially active earthquake faults are located in the City of Los Alamitos, the entire southern California region is considered to be seismically active. Earthquakes create seismic hazards such as ground shaking, ground displacement, subsidence, and uplift. These actions can, in turn, induce secondary hazards such as ground failure, liquefaction, landslides,seismically induced water waves(tsunamis and seiches),and dam failure. City of La Palma General Plan The City of La Palma General Plan Community Safety Element (2014) sets forth goals and policies to protect and safeguard La Palma residents from urban fires, crime, hazardous materials incidents, flooding, earthquakes, and exposure to excessive noise levels. Geologic and seismic hazards detailed in this element include earthquakes and liquefaction. While no active or potentially active faults are located within the City of La Palma,the entire southern California region is considered to be seismically active. "Goal 4: Building a community with maximum feasible protection from seismic and geologic hazards "Policy 4.2: Require all new development to comply with the most recent Uniform Building Code seismic design standards and State of California seismic building standards." City of Cypress General Plan The City of Cypress Safety Element (2000) is an official guide for the City Council, government agencies, and individuals to identify and understand potential hazards confronting Cypress.The Element examines manmade and natural hazards that could endanger the public safety and welfare. These concerns are subsequently incorporated into goals, policies, and implementation measures to reduce the impacts of hazards. The Safety Element helps protect the community from natural hazards, including floods, earthquakes,ground rupture, and landslides. "Goal SAF-2: Protect life and property in Cypress from seismic events and resulting hazards. "Policy SAF-2.1:Identify and evaluate existing structures for structural safety. Encourage building owners to undertake seismic retrofit improvements. "Policy SAF-2.2:Implement the Uniform Building Code's seismic standards for construction of new buildings and maintain seismic safety of existing structures. "Policy SAF-2.3: Require the review of soils and geologic conditions, and if necessary on-site borings, to determine liquefaction susceptibility of a proposed project site." Rehabilitation of Western Regional Sewers, Project 3-64 3-85 3.5-Geology and Soils City of Buena Park General Plan The City of Buena Park General Plan Safety Element (2010) identifies and evaluates public health and safety hazards, and outlines means of limiting risks and minimizing losses that occur as a result of natural and human-caused disasters. Natural hazards that threaten Buena Park include earthquakes, floods, and severe rainstorms. The City of Buena Park is located in a seismically active region, with a number of faults in close proximity, and is subject to seismic ground shaking and liquefaction due to the close proximity and potential earthquake magnitude of nearby faults. "Goal SAF-1: Decrease in the potential risk of seismic and geologic hazards to the community. 'Policy SAF-1.2:Enforce the requirements of current building codes relative to seismic design for all new development or redevelopment. 'Policy SAF-1.3:Require geologic and soils reports for all new development or redevelopment, especially in identified areas of the Norwalk Fault Zone and areas with high liquefaction potential. "Policy SAF-1.4:Require appropriate mitigation measures and/or conditions of approval relative to terrain, soils, slope stability, and erosion for new development or redevelopment in orderto reduce hazards." City of Anaheim General Plan The City of Anaheim General Plan Safety Element (2004): identifies potential hazards that can significantly impact the City; provides policies to minimize potential dangers to residents, workers, and visitors and to reduce the level of property loss due to a potential disaster; and identifies ways to respond to crisis situations. "Goal 1.1: Minimize the risk to public health and safety and disruptions to vital services, economic vitality,and social order resulting from seismic and geologic activities. 'Policy 1: Minimize the risk to life and property through the identification of potentially hazardous areas, adherence to proper construction design criteria, and provision of public information. 'Policy 2: Require geologic and geotechnical investigations in areas of potential seismic or geologic hazards as part of the environmental and/or development review process for all structures and enforce structural setbacks from faults that are identified through those investigations. 'Policy 3: Require that lifelines (i.e.,water, sewer,electrical,gas facilities, and communication and transportation facilities that are needed in the event of an earthquake,flood,or Rehabilitation of Western Regional Sewers, Project 3-64 3-86 3.5-Geology and Soils other natural disaster) crossing a fault be designed to resist the occurrence of fault rupture." 3.5.2 Existing Conditions 3.5.2A Regional Geologic Setting The Project area is located in the Los Angeles Basin,which is the coastal sediment-filled plain located at the north end of the Peninsular Ranges province in southern California. The coastal plain is bounded by the Elysian, Repetto, and Puente hills to the northeast; the Santa Ana Mountains to the southeast; the San Joaquin Hills to the south;and the Pacific Ocean to the west.The basin is a coastal lowland area that is characterized by gentle slopes of alluvial deposits and coastal mesas. Natural alluvial soils consist predominantly of interbedded layers of damp to saturated medium-dense to dense silty sand, poorly graded sand,and stiff to very stiff silty clay(OCSD 2005). Orange County is a geographically diverse area of mountains, hills,flatlands, and shoreline.The Cities of Anaheim, Buena Park, Cypress, La Palma, Los Alamitos, and Seal Beach are located in the western portion of Orange County, near the Los Angeles County border. The portion of the coastal plain within Orange County is underlain by a deep structural depression primarily containing sedimentary rocks.The subsurface of the County varies in thickness and lithology due to the rapid rate of deposition of rock units, folding, and faulting. The sedimentary deposits of the coastal plain are a hybrid of marine and continental sediment. A significant amount of the sedimentary deposits have been removed over time due to erosion(City of Fullerton 2012). 3.5.2•2 Soils The existing soils underlying the Project area include alluvium deposits (a collection of a variety of materials, including fine particles of silt and clay and larger particles of sand and gravel). The Project area is urbanized and is generally characterized as built out. As a result, surface soils in the area may no longer reflect the natural soil associations and characteristics identified below since the Project area has been developed. According to the U.S. Department of Agriculture Natural Soil Conservation Service (USDA NRCS 2015), the soil types and characteristics of those soils within the Project area include the following: Balsa Silt Loam. Drained (Seal Beach Blvd. Interceptor, Los Alamitos Sub-trunk, Westside Relief Interceptor and Westside Pump Station) This nearly level soil generally occurs on large alluvial fans. If the soil is bare, runoff is slow and the erosion hazard is slight. The water capacity of this soil is 11.5 to 12.5 inches, which is the range of available water that can be stored in soil and is available for growing crops. Rehabilitation of Western Regional Sewers, Project 3-64 3-87 3.5-Geology and Soils Balsa Silt Clay Loam,Drained (Seal Beach Blvd. Interceptor, Los Alamitos Sub-trunk) This nearly level soil generally occurs on large alluvial fans. Runoff is very slow and the erosion hazard is none to slight.The water capacity of this soil is 11.5 to 12.5 inches,which is the range of available water that can be stored in soil and is available for growing crops. Metz Loamy Sand (Orange-Western Sub-trunk) This nearly level to gently sloping soil generally occurs on large fans and on flood plains. If the soil is bare,runoff is slow and the erosion hazard is slight. It has a water capacity of 4.0 to 6.0 inches. Hueneme Fine Sandy Loam, Drained(Westside Relief Interceptor,Los Alamitos Sub-trunk) This nearly level to gently sloping soil generally occurs on large fans and on flood plains. If the soil is bare,runoff is slow and the erosion hazard is slight. It has a water capacity of 7.0 to 9.0 inches. Metz Loamy Sand, Moderate Fine Substratum(Orange-Western Sub-trunk) This nearly level to gently sloping soil generally occurs on large fans and on flood plains. If the soil is bare,runoff is slaw and the erosion hazard is slight. It has a water capacity of 4.0 to 6.0 inches. San Emiedio Fine Sandy Loam, 0 to 2 Percent Slopes (Westside Relief Interceptor, Los Alamitos Sub- trunk This nearly level soil generally occupies alluvial fans on flood plains and along stream channels. If the soil is bare, runoff is slow and the erosion hazard is slight.The soil has an available water capacity of 7.0 to 9.0 inches. San Emiedio Fine Sandy Loam, Moderately Fine Substratum, 0 to 2 Percent Slopes (Westside Relief Interceptor, Los Alamitos Sub-trunk) This nearly level soil generally occurs on alluvial fans on flood plains and along stream channels. Permeability is moderately slow in the underlying material. Runoff is slow and the erosion hazard is slight.Available water capacity for this soil is 7.0 to 10.0 inches. 3.5•2.3 Geologic Hazards All of Southern California, including Orange County, lies within a seismically active area and thus is subject to some degree of seismic shaking. Although the Project area is not located within an Alquist- Priolo earthquake fault zone, it is located within the boundaries of the Los Alamitos fault(Late Holocene, not active) and is located in an area considered to be seismically active between two major active fault zones: the Newport-Inglewood fault zone and the Whittier-Elsinore fault zone. Table 3.5-1 lists known active faults in the region and their distance to the Project area. The location of these faults relative to the Project area is shown on Figure 3.5-1. Rehabilitation of Western Regional Sewers, Project 3-64 3-88 3.5-Geology and Soils Table 3.5-1: Distance from the Project Area to Active Faults within the Region r Los Alamitos 0.0 Newport-Inglewood 1.1 El Modena 11.4 Whittier-Elsinore 7.6 Data Source:California Geologic Society(2010) Surface Rupture Surface rupture is an offset of the ground surface when fault rupture extends to the Earth's surface.The Project area is located within the boundaries of the Los Alamitos fault and approximately 1 mile from the active Newport—Inglewood fault zone. Specifically, the Los Alamitos Sub-trunk alignment is located over the inactive Los Alamitos fault. According to the Southern California Earthquake Data Center, the age of the fault is uncertain and the fault is indistinct. The fault may be part of the larger Compton-Los Alamitos fault system. Additionally,the Project area is highly urbanized and generally built out; and the locations of faults are not well defined. Typically, faults rupture along existing fault planes, and the risk for fault rupture hazard is higher for sites located over an active fault. The Los Alamitos Sub-trunk portion of the Project area may have a higher risk of fault rupture hazard in comparison to the rest of the Project area because of its proximity to the Los Alamitos fault. Overall, based on the existing mapped fault location, the probability of damage due to surface ground rupture is low to moderate due to the lack of active faults within the immediate Project area. Ground shaking Ground shaking refers to all aspects of motion of the earth's surface resulting from an earthquake, and is normally the major cause of damage in seismic events. The extent of ground shaking is controlled by the magnitude and intensity of the earthquake, distance from the epicenter, and local geologic conditions. The closest active fault to the project site is the Los Alamitos fault, which is located within the project limits. The potential probable earthquake magnitude for this fault has not been predicted. The nearest major fault zone near the Project area is the Newport—Inglewood fault zone, which is located within 1 mile of the Project area. It is predicted to be capable of a 6.0 to 7.4 magnitude earthquake on the moment magnitude (Mw) scale. An earthquake of this magnitude could generate strong to violent seismic shaking within the Project area,which could result in structural damage. Liquefaction Potential Liquefaction occurs when vibrations or water pressure within a mass of soil cause the soil particles to lose contact with one another. As a result, the soil behaves like a liquid, has an inability to support weight, and can flow down very gentle slopes. This condition is usually temporary and is most often caused by an earthquake vibrating water-saturated fill or unconsolidated soil. Liquefaction may occur at sites that sit on unconsolidated younger alluvial material and have a high groundwater table Rehabilitation of Western Regional Sewers, Project 3-64 3-89 3.5-Geology and Soils (groundwater is within 25 feet of the surface). Figure 3.5-1 shows areas mapped by the California Geologic Service that are potentially liquefiable.According to the California Geological Survey,the entire Project area is located within a Liquefaction Hazard Zone. It is anticipated that the sandy alluvial deposits beneath the Project area are susceptible to soil liquefaction during a large earthquake event. 3-5•3 Thresholds ofSigirrificance The following significance criteria are based on Appendix G of the California Environmental Quality Act (CEQA) Guidelines (14 California Code of Regulations 15000 et seq.) and are used to evaluate potential Project impacts related to geology and soils. Impacts on geology and soils would be significant if the proposed Project would: GEO-1: Expose people or structures to potential substantial adverse effects, including the risk of loss,injury, or death involving: • Rupture of a known earthquake fault, as delineated on the most recent Alquist- Priolo Earthquake Fault Zoning Map issued by the State Geologist for the area or based on other substantial evidence of a known faults • Strong seismic ground shaking • Seismic-related ground failure, including liquefaction Other impact significance criteria for Geology and Soils, identified in Appendix G of the CEQA Checklist, have been evaluated previously in Section 4.6 of the Initial Study for the proposed Project(See Appendix A).This previous evaluation determined that the proposed Project would result in either no impact or in less than significant impacts from Geology and Soils under these criteria. As a result, the following impact significance criteria have not been evaluated further within this Environmental Impact Report (EIR): • Result in substantial soil erosion or the loss of topsoil? • Be located on a geologic unit or soil that is unstable or that would become unstable as a result of the project, and potentially result in on- or off-site landslide, lateral spreading, subsidence, liquefaction,or collapse? • Be located on expansive soil, as defined in Table 18-1-B of the Uniform Building Code (1994), creating substantial risks to life or property? • Have soils incapable of adequately supporting the use of septic tanks or alternative wastewater disposal systems where sewers are not available for the disposal of wastewater? Refer to Division of Mines and Geology Special Publication 42. Rehabilitation of Western Regional Sewers, Project 3-64 3-90 3.5-Geology and Soils 3.5.4 Impact Analysis The differences between the two alternatives are minor. Thus, no differences between the two build alternatives are anticipated, and the impacts described in this section are the same for Build Alternative 1 and Build Alternative 2. GEO-1: Expose people or structures to potential substantial adverse effects, including the risk of loss,injury,or death involving • Rupture of a known earthquake fault, as delineated on the most recent Alquist-Priolo Earthquake Fault Zoning Map issued by the State Geologist for the area or based on other substantial evidence of a known fault? • Strong seismic ground shaking? • Seismic-related ground failure,including liquefaction? 3.5.4•1 Construction Impacts Rupture of a known earthquake fault, as delineated on the most recent Alquist-Priolo Earthquake Fault zoning Map issued by the State Geoloeist for the area or based on other substantial evidence of a known fault No known active or potentially active faults lie within the proposed Project area (the Los Alamitos fault is inactive). Additionally, the proposed Project area is not located within an Alquist-Priolo Earthquake Fault Zone. The nearest active fault zone is the Newport-Inglewood fault zone located approximately 1.1 miles southwest of the Project area. Based on the existing mapped fault locations, ground surface rupture on or adjacent to the Project area is not likely due to the absence of known active faults traversing the Project area. In addition,the proposed Project would be designed in accordance with the latest CBC(2013).The proposed Project components would be constructed in accordance with the ECMs described in Table 2.10-1. Furthermore, requirements of the U.S. Department of Labor Occupational Safety and Health Administration and the California Health and Safety Code would reduce the potential for risks related to seismic events(e.g., preparation of an Earthquake Preparedness and Response Plan). These include specifications for excavation, the composition of fill, and materials to be used to ensure construction worker safety. Construction impacts associated with fault rupture would therefore be less than significant. Strong Seismic Ground Shakin¢ Despite the low likelihood of a large regional earthquake occurring during the construction period,there is the potential for risks to construction workers related to strong seismic ground shaking.The proposed project would be constructed in accordance with latest CBC (2013). Furthermore, the proposed project components would be constructed in accordance with the ECMs described in Table 2.10-1 including the applicable design and construction requirements of OCSD, and Cities of Seal Beach, Los Alamitos, La Palma, Cypress, Buena Park and Anaheim. In addition, as listed in Table 2.10-1, proper geotechnical Rehabilitation of Western Regional Sewers, Project 3-64 3-91 3.5-Geology and Soils characterization and design of shoring systems would be developed through further subsurface evaluations; and the implementation of all geotechnical recommendations for excavation activities would be required. Excavations that are unstable or are deeper than 4 feet would be shored.Therefore, construction impacts associated with seismic ground shaking would be less than significant. Seismic-related Ground Failure.includine Liquefaction The proposed Project is located in an area mapped as a liquefaction hazard zone (see Figure 3.5-1 on page 3-93). The proposed Project will be constructed in accordance with latest CBC (2013). Furthermore, the proposed Project components would be constructed in accordance with the ECMs described in Table 2.10-1, including the applicable design and construction requirements of OCSD and Cities of Seal Beach, Los Alamitos, La Palma, Cypress, Buena Park and Anaheim. In addition, as listed in Table 2.10-1, proper geotechnical characterization and subsurface evaluations are being conducted as part of Project design; and compliance with all recommendations regarding specific measures to reduce risks of liquefaction (e.g., subsurface soil improvement, dynamic compaction, compaction grouting) would be required for construction activities. The proposed Projects construction impacts related to seismic- related ground failure, including potential liquefaction,would be less than significant. 3.5.4•2 OPerationallmpacts Operations under both build alternatives would consist of ongoing activities related to operation and maintenance of the Western Regional Sewer lines and the Westside Pump Station, including routine maintenance, cleaning of sewer lines and manholes, visual inspections, closed-circuit television and camera inspection, flow-monitoring, as-needed repairs and chemical dosing for odor and corrosion control, which are consistent with the existing operational impacts of the Western Regional Sewer lines and the Westside Pump Station. Since the project would be constructed in accordance with the latest CBC (2013) design and the construction requirements of OCSD and the Cities of Seal Beach, Los Alamitos, La Palma, Cypress, Buena Park and Anaheim, no operational impacts associated with the rupture of a known earthquake fault; strong seismic-related ground shaking; or seismic-related ground failure, including liquefaction, are anticipated;and impacts would be less than significant. 3.5.4.3 No Build[Alteraative Under the No Build Alternative, there would be no rehabilitation or replacement of the Western Regional Sewers or Improvements at the Westside Pump Station other than routine operations and maintenance activities as discussed in Section 2.6.The No Build Alternative would not expose people or structures to potential substantial adverse effects, including the risk of loss, injury, or death due to fault rupture,strong seismic shaking, or seismic-related ground failure, including liquefaction. 3.5.5 Mitigation Measures No mitigation measures are required.

Short-term (construction) and long-term (operational) impacts associated with GHGs that would potentially occur as a result of the proposed Project were evaluated and summarized below. 3.6.1 Regulatory Setting 3.6.1.1 Federal Climate change is associated with long-term changes in temperature, precipitation, wind patterns, and other elements of the earth's climate system. An ever-increasing body of scientific research attributes these climatological changes to anthropogenic GHG emissions, particularly those generated from the production and use of fossil fuels. While climate change has been a concern for several decades, the establishment of the Intergovernmental Panel on Climate Change by the United Nations and World Meteorological Organization in 1988 has led to increased efforts devoted to GHG emissions reduction and climate change research and policy development. These efforts are primarily concerned with the emissions of GHGs generated by human activity, including carbon dioxide (CO,), methane (CH4), nitrous oxide (N20), tetrafluoromethane, hexafluoroethane, sulfur hexafluoride, HFC-23 (fluoroform), HFC-134a (s, s, s, 2- tetrafluoroethane),and HFC-152a (difluoroethane). Although climate change and GHG emissions reduction are concerns at the federal level, no federal regulations or legislation have been enacted that specifically address GHG emissions reductions and climate change at the project level. Climate change and its associated effects are being addressed through various efforts at the federal level to improve fuel economy and energy efficiency, such as the "National Clean Car Program" and Executive Order 13514 — Federal Leadership in Environmental, Energy and Economic Performance. Executive Order 13514 is focused on reducing GHGs internally in federal agency programs and operations but also directly through federal agencies participating in the interagency Climate Change Adaptation Task Force, which is engaged in developing a United States (U.S.) strategy for adaptation to climate change. On April 2, 2007, in Massachusetts v. EPA, 549 U.S. 497 (2007), the Supreme Court found that greenhouse gases are air pollutants covered by the Clean Air Act and that the U.S. Environmental Protection Agency (USEPA) has the authority to regulate GHGs. The Court held that the USEPA Administrator must determine whether or not emissions of GHGs from motor vehicles cause or contribute to air pollution which may reasonably be anticipated to endanger public health or welfare,or whether the science is too uncertain to make a reasoned decision. Rehabilitation of Western Regional Sewers, Project 3-64 3-94 3.6-Greenhouse Gas Emissions On December 7, 2009, the USEPA Administrator signed two distinct findings regarding GHGs under section 202(a)of the Clean Air Act: • Endangerment Finding:The Administrator found that the current and projected concentrations of the six key well-mixed greenhouse gases — carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride — in the atmosphere threaten the public health and welfare of current and future generations. • Cause or Contribute Finding: The Administrator found that the combined emissions of these well-mixed greenhouse gases from motor vehicle engines contribute to the greenhouse gas pollution,which threatens public health and welfare. Although these findings did not themselves impose any requirements on industry or other entities,this action was a prerequisite to finalizing the USEPA's Proposed Greenhouse Gas Emission Standards for Light-Duty Vehicles, which was published on September 15, 2009 (USEPA OTAQ 2009). On May 7, 2010, the final Light-Duty Vehicle Greenhouse Gas Emissions Standards and Corporate Average Fuel Economy Standards were published in the Federal Register. USEPA and the National Highway Traffic Safety Administration (NHTSA) are taking coordinated steps to enable the production of a new generation of clean vehicles with reduced GHG emissions and improved fuel efficiency from on-road vehicles and engines. These next steps include developing the first ever GHG regulations for heavy-duty engines and vehicles as well as additional light-duty vehicle GHG regulations. These steps were outlined by President Obama in a memorandum on May 21, 2010 (White House 2010). The final combined USEPA and NHTSA standards that make up the first phase of this national program apply to passenger cars, light-duty trucks, and medium-duty passenger vehicles, covering model years 2012 through 2016. The standards require these vehicles to meet an estimated combined average emissions level of 250 grams of carbon dioxide per mile, equivalent to 35.5 miles per gallon (mpg) if the automobile industry were to meet this carbon dioxide level solely through fuel economy improvements. Together, these standards are estimated to reduce GHG emissions by 960 million metric tons and 1.8 billion barrels of oil over the lifetime of the vehicles sold under the program (model years 2012 through 2016). On January 24, 2011, the USEPA along with the U.S. Department of Transportation and the State of California announced a single time frame for proposing fuel economy and GHG standards for cars and light-trucks in the model years 2017 through 2025. Shortly thereafter (November 16, 2011), the new standards were proposed to be implemented during the same model year time frame, which signals continued collaboration that could lead to an extension of the current National Clean Car Program. These standards were finalized and posted in the Federal Register for 2017 or later models on October 15,2012 (Federal Register 62624). Rehabilitation of Western Regional Sewers, Project 3-64 3-95 3.6-Greenhouse Gas Emissions 3.6.1.2 State With the passage of several pieces of legislation, including State Senate and Assembly Bills and Executive Orders, California has launched an innovative and proactive approach to addressing GHG emissions and climate change at the state level. Executive Order 5-3-05 Executive Order 5-3-05, signed in June 2005 by Governor Arnold Schwarzenegger, states that California is vulnerable to the impacts of climate change and that increased temperatures could reduce the Sierra Nevada snowpack, further exacerbate California's air quality problems, and potentially cause a rise in sea levels. To address those concerns, the Executive Order established the state's first GHG emissions targets: • Reduce GHG emissions to 2000 levels by 2010 • Reduce GHG emissions to 1990 levels by 2020 • Reduce GHG emissions to 80 percent below 1990 levels by 2050 This Executive Order requires biannual reports on progress made toward meeting these targets and the global warming impact on California. Global Warming Solutions Act of 2006 In September 2006, the State Legislature passed, and Governor Schwarzenegger signed, Assembly Bill (AB) 32 (Chapter 488, States of 2006), the Global Warming Solutions Act of 2006, which set the 2020 GHG emissions reduction goal into law. It directed the California Air Resources Board (GARB) to begin developing discrete early actions to reduce GHG emissions while also preparing the Climate Change Scoping Plan, which outlines a framework of measures that would eventually be adopted and implemented to reach AB 32 goals (GARB 2015c). CARB approved the Climate Change Scoping Plan in 2008 and updated it in May 2014. Regulations are being phased in over time. Adopted regulations include the California Energy Commission's 33 percent Renewable Portfolio Standard, the CARB Cap- and-Trade Program, and the CARB Low Carbon Fuel Standard. Relevant recommended actions of the updated Climate Change Scoping Plan are generally related to transportation/goods movement and gases with a high potential to result in global warming(GWP)including CO2,Cld ,and NzO. The reporting of GHG emissions by major sources is required by AB 32. In 2007, CARB established the Regulation for the Mandatory Reporting of Greenhouse Gas Emissions (MRR). Revisions to this GHG reporting regulation were approved by the California Office of Administrative Law, which became Rehabilitation of Western Regional Sewers, Project 3-64 3-96 3.6-Greenhouse Gas Emissions effective on January 1, 2012. Facilities that emit 10,000 metric tons of carbon dioxide equivalents10 (MtCO2e)or more per year are required to submit annual reports to CARB. Subsequently, the SCAQMD established a significance threshold of 10,000 metric tons per year for CO2 equivalents (MtCO2e) including NO, and CH4 from industrial facilities for which it is the lead agency (SCAQMD 2008). Senate Bill 97 Senate Bill (SB) 97 was passed by the State Legislature and approved by Governor Schwarzenegger in August 2007. SB 97 acknowledges that climate change is a prominent environmental issue that requires analysis under the California Environmental Quality Act(CEQA).The California Natural Resources Agency adopted amendments to the CEQA Guidelines to address the analysis and mitigation of GHG emissions. The amendments to the CEQA Guidelines implementing SB 97 became effective on March 18,2010. Executive Order B-16-2012 Executive Order B-16-2012, signed in March of 2012 by Governor Edmund G. Brown, ordered CARB,the California Energy Commission, the California Public Utilities Commission (CPUC), and other relevant agencies to establish benchmarks to achieve numerous goals set for 2015, 2020, and 2025 to reduce GHG emissions in California. These goals include accommodation of zero-emission vehicles in major metropolitan areas, expansion of manufacturing capabilities of zero-emission vehicles, accessibility of zero-emission vehicles to mainstream consumers, and integration of electrical vehicle charging into the electricity grid. Governor Brown also set a target such that GHG emissions from the transportation sector would be reduced to 80 percent less than 1990 levels by 2050. Executive Order B-30-15 In April 2015, Governor Brown signed Executive Order B-30-15, establishing a new interim statewide GHG emission reduction target of 40 percent below 1990 levels by 2030. The interim reduction target was established in order to ensure California meets its goal of reducing GHG emissions to 80 percent below 1990 levels by 2050. Executive Order B-30-15 requires state agencies to consider climate change in their planning and investment decisions,giving priority to actions that reduce GHG emissions. Executive Order 5-20-04 Executive Order S-20-04 outlines guiding policies that call for reducing electricity consumption in existing and new State-owned buildings by 20 percent by 2015, through designing, constructing, and operating all new and renovated State-owned facilities to Leadership in Energy and Environmental Design (LEED) "Silver" or higher certified standards. tp A metric used to compare emissions of various greenhouse gases.It is the mass of carbon dioxide that would produce the same estimated radiative forcing as a given mass of another greenhouse gas.Carbon dioxide equivalents are computed by multiplying the mass of the gas emitted by its global warming potential. Rehabilitation of Western Regional Sewers, Project 3-64 3-97 3.6-Greenhouse Gas Emissions Executive Order B-18-12 In April 2012, Governor Brown signed a green building Executive Order B-18-12 directing state agencies and departments to take immediate action for State government buildings to serve as models for green building. Executive Order B-18-12 supports California's climate goals by requiring state agencies to reduce entity-wide GHG emissions by 10 percent by 2015 and 20 percent by 2020. It also includes requirements to reduce grid-based energy purchases by at least 20 percent by 2018, achieve LEED "Silver" certification for new or major renovated State buildings, retrofit half of existing buildings to be Zero Net Energy (ZNE) buildings by 2025, and implement electric vehicle charging stations to accommodate future infrastructure demand. 3.6.1.3 Local The proposed Project is located within the South Coast Air Basin (SCAB) under the jurisdiction of the SCAQMD. SCAQMD Rule 2701 establishes a program to encourage, quantify,and certify voluntary, high- quality certified GHG reductions in the SCAQMD. The proposed Project would adhere to the following SCAQMD regulations: • SCAQMD Regulation XXVI I, Rule 2702 (2010)-Climate and Greenhouse Gases o Rule 2702 creates a program for GHG emissions reduction in the SCAQMD by funding reduction projects or purchasing reductions from other parties In addition,the proposed Project is located within the jurisdictions of Orange County and six cities. GHGs and climate change are managed through land use and development planning practices, which are implemented through the cities' general planning processes. The following are city plans applicable to GHGs within the Project area: • City of La Palma-General Plan Greenhouse Gas Background Report(2012) o Goal 05-4: Encourage the use of sustainable practices to reduce energy use and help curb global climate change. • OS-4.4: Adopt practices that minimize the amount of materials entering the waste stream. Encourage recycling and composting in all sectors. • OS-4.6: Collaborate with State and regional agencies to improve air quality and implement State air quality and climate change goals. • City of Buena Park-General Plan o Principle: Reduction of Greenhouse Gas Emissions(GHG) • Goal CS-21:GHG emissions inventories established for all sectors within the City. • Goal CS-22: An action plan established to reduce or encourage reductions in GHG emissions from all sectors within the City. Rehabilitation of Western Regional Sewers, Project 3-64 3-98 3.6-Greenhouse Gas Emissions • Goal CS-23: Incentives aimed at reducing unnecessary energy and water consumption are implemented. • City of Anaheim General Plan — GHG Reduction Plan — Sustainable Electric & Water Initiatives (July 2015) o Develop a clear and comprehensive long term strategic framework to reduce greenhouse gas emissions,and have an appreciable impact to the environment. o Sustainable management of the City's power and sustainability measures including control of waste water,storm water,and potable discharges. 3.6.2 Existing Conditions Climate change refers to global and regional variations in the normal weather of the earth (wind patterns, storm intensity, precipitation, and temperature) that occur over time. While the earth has gone through many natural changes in climate in its history, scientists generally agree that the earth's climate is currently changing at an accelerated rate and will continue to do so for the foreseeable future. Anthropogenic (human-caused) GHG emissions contribute to this rapid change. Carbon dioxide makes up the largest component of these GHG emissions,stemming mostly from fossil-fuel combustion. Other prominent sources of GHGs include CH4 and N20,which are primarily transportation related. Many GHGs occur naturally. Water vapor is the most abundant GHG and makes up approximately two- thirds of the natural greenhouse effect; however, burning of fossil fuels and other human activities are adding to the concentration of GHGs in the atmosphere. Many GHGs remain in the atmosphere for time periods ranging from decades to centuries. California's annual statewide GHG emission inventory is an important tool for establishing historical emission trends and tracking California's progress in reducing GHGs. In concert with data collected through various AB 32 programs, the GHG inventory is a critical piece in demonstrating the state's progress in achieving the statewide GHG target of 1990 levels by 2020.The inventory provides estimates of anthropogenic GHG emissions within California, as well as emissions associated with imported electricity; natural sources are not included in the inventory. The CARB is responsible for maintaining and updating California's GHG Inventory per Health and Safety Code§39607.4. Statewide emission estimates rely on state, regional, or federal data sources and on aggregated facility- specific emission reports from CARB's MRR. The current inventory uses GWP values from the Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report, consistent with current international and national GHG inventory practices. The 2014 inventory estimates 441.5 million megatons of carbon dioxide equivalents KOM from California sources, including electricity generation, industrial,transportation,commercial,agricultural, and residential. Direct COz accounts for 84.3 percent of emissions, followed by CH4 (9 percent) and N,O (2.8 percent), with the remainder comprising gases with high GWP (3.9 percent). The SCAQMD 2009 Annual Report on its carbon footprint estimates that purchased electricity (54 percent), stationary sources (35 percent), and mobile sources (11 percent), Rehabilitation of Western Regional Sewers, Project 3-64 3-99 3.6-Greenhouse Gas Emissions respectively, account for GHG emissions generated by vehicle fleets and facilities owned and/or operated by SCAQM D. 3.6.3 Thresholds of Significance The following significance criteria are based on Appendix G of the California Environmental Quality Act (CEQA) Guidelines (14 California Code of Regulations 15000 et seq.) and are used to determine the significance of potential GHG impacts. Impacts to GHG emissions would be significant if the proposed Project would: GHG-1: Generate greenhouse gas emissions, either directly or indirectly,that may have a significant impact on the environment GHG-2: Conflict with an applicable plan, policy, or regulation adopted for the purpose of reducing the emissions of greenhouse gases 3.6.4 Impact Analysis Construction of the proposed Project has the potential to create temporary GHG emissions. Construction methods would include open-trench excavation, sewer lining and manhole rehabilitation (i.e., cured-in-place pipe installation), and pump station rehabilitation. Sewer lining and manhole rehabilitation would include cured-in-place pipe (CIPP) installation using a felt truck or boiler truck with generators and air compressors. The pump station rehabilitation would involve delivery and replacement of large-volume pumping equipment for the force main, reconstruction of the wet well, and the addition of either an air scrubber or air jumper line. The proposed Project would construct sewer pipelines in a linear fashion for open-cut trenching and CIPP installation, completing approximately 50 to 150 feet of pipeline per day. The proposed Project would require excavation for installation of new 21-to 39-inch pipes at depths of up to 22.7 feet below ground surface (bgs) and 31.3 feet bgs for Build Alternative 1 and Build Alternative 2, respectively. Trenches to accommodate the new pipe would be up to 7 feet wide. The construction area associated with replacement would be up to 1,000 feet long and 25 feet wide. As discussed in Section 2.5.4 Construction Schedule and Cost, the construction schedule allows sufficient time from March 2019, through March 2023 (approximately 4 years or 1,460 days) to construct each Project segment sequentially for either build alternative; however, construction activities are anticipated to last for approximately 24 to 30 months during this time frame. Section 2.5 provides a detailed description of construction methods. Appendix B summarizes the construction method, construction equipment type, quantity of equipment, hours of operation, number of working days, and number of workers on site for each activity. Additionally, minor excavations approximately 15 feet wide by 30 feet long would be required for each manhole replacement/rehabilitation on all project segments where exit/entry pits are required (e.g.,for Rehabilitation of Western Regional Sewers, Project 3-64 3-100 3.6-Greenhouse Gas Emissions alternative construction methods discussed in Chapter 2.0) and for the improvements at the Westside Pump Station. Construction equipment and materials would be held in staging areas in parking lots, vacant lots, or segments of street lanes that are temporarily closed to minimize hauling trips and long-term disruption. Direct emissions of GHGs in terms of CO2e from construction of the proposed Project were determined using the California Emission Estimator Model (CaIEEMod) v 2013.2.2 developed for the California Air Pollution Control Officers Association (CAPCOA) by SCAQMD and other California air districts (EIC 2013). The model quantifies direct emissions from construction for a variety of land use projects. GHi Generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment? 3.6.4.1 Constructfonlmpacts Table 3.6-1 summarizes GHG emission estimates from on-site (off-road equipment)and off-site (on-road haul trucks, delivery trucks, and worker vehicles) sources associated with simultaneous construction activities for all Project segments from 2019 to 2023. Per SCAQMD guidance, annual emissions for Build Alternatives 1 and 2 were amortized over an estimated 30-year project lifespan from construction completion in 2023;therefore, emissions during the initial construction year(2019) were amortized for 34 years. Emissions were amortized for 33 to 30 years for the next 4 construction years, respectively. In other words, the 30-year amortization extends from the end of construction, but in this case includes the four preceding years, so the beginning construction emissions span 34 years; year 1 spans 33 years, year 2 spans 32 years,year 3 spans 31 years,and year 4 spans 30 years.

MT: metric tons per year COi:carbon dioxide MTCHa:metric methane N20:nitrous oxide COze:carbon dioxide equivalent Rehabilitation of Western Regional Sewers, Project 3-64 3-101 3.6-Greenhouse Gas Emissions Common Build Alternative Element Impacts Because the GHG analysis considers GHG emissions from all project elements amortized over the lifetime of the Project for each build alternative as a whole rather than for each specific Project segment, there are no common elements to the impact analysis. Overall,the Build Alternative 1 annual GHG emissions would be lower than those associated with Build Alternative 2 because of the greater amount of excavation/pipe replacement and more equipment-intensive construction activities associated with Build Alternative 2. Build Alternative 1 As shown in the Table 3.6-1, annual amortized emissions during the construction period would be well below the SCAQMD 10,000 MtCOze threshold for Build Alternative 1. There would be some slight variation in the annual and amortized emissions estimates depending on the order in which project segments are constructed and the amount of potential construction overlap. The numbers in the table assume the project segments with the highest daily emissions of GHGs and criteria pollutants, the Los Alamitos Sub-trunk and the Westside Relief Interceptor, would be constructed first. The greatest amount of GHGs in terms of total CO2e would be generated in the first year of construction in 2019 with a general reduction in annual emissions in subsequent years through 2023 as fuel standards improve and construction activities become less intense. Peak annual emission of 153.85 MtCOze would begin in the fifth(final)year of construction and continue through the twenty-fifth year after project completion; therefore,construction GHG impacts for Build Alternative 1 would be less than significant. Build Alternative 2 As shown in the Table 3.6-1, annual amortized emissions during the construction period would also be well below the SCAQMD 10,000-MtCO,e threshold for Build Alternative 2. There would be some slight variation in the annual and amortized emissions estimates depending on the order in which project segments are constructed and the amount of potential construction overlap. The numbers in the table assume the project segments with the highest daily emissions of GHGs and criteria pollutants, the Los Alamitos Sub-trunk and the Westside Relief Interceptor, would be constructed first. The greatest amount of GHGs in terms of total CO2e would be generated in the first year of construction in 2019 with a general reduction in annual emissions in subsequent years through 2023 as fuel standards improve and construction activities become less intense. Peak annual emission of 193.91 MtCOze would begin in the fifth(final)year of construction and continue through the twenty-fifth year after project completion; therefore,construction GHG impacts for Build Alternative 2 would be less than significant. 3.6.4.2 Operational Impacts Operational air quality emissions for both of the build alternatives would be associated with vehicle trips to complete routine maintenance; clean sewer lines and manholes; perform visual inspections utilizing closed-circuit television and camera inspection; conduct flow-monitoring, as-needed repairs, and chemical dosing for odor and corrosion control; and operate the air scrubber if it is selected for the Rehabilitation of Western Regional Sewers, Project 3-64 3-102 3.6-Greenhouse Gas Emissions proposed Project. These activities would occur periodically and are already occurring under existing conditions. Potential repair activities would be temporary and not a source of long-term operational GHG emissions. Therefore, the Project would not generate significant GHG emissions, and operational impacts would be less than significant. GHG-2: Conflict with an applicable plan,policy, or regulation adopted for the purpose of reducing the emissions of greenhouse gases? 3.6.4.3 Construction and Operational Impacts The CARB 2016 Edition of the California GHG Emission Inventory, California Greenhouse Gas Emissions for 2000 to 2014 — Trends of Emissions and Other Indicators (GARB 2016a), summarizes statewide emissions of GHGs from seven source categories in the AB 32 Scalping Plan including transportation, industrial, electric power, commercial and residential, agriculture, recycling and waste, and high global warming potential which consist primarily of substitutes for ozone-depleting substances (GARB 2015d). Trends in GHGs indicate a 1.5-million Mt002e decrease from 2012 to 2013 and 7-percent decrease since peak levels in 2004. As described previously in Section 3.6.2, emissions from the transportation sector represented 37 percent of total emissions in 2014, with the majority of emissions coming from on-road vehicles. Trends in this sector indicate an 11-percent decrease from 2007 peak levels, primarily due to low-carbon fuel standards and incentives for vehicles using alternative fuel such as compressed natural gas. Emissions from the industrial sector represented 24 percent of statewide GHG emissions in 2014, with emissions decreasing by approximately 6 percent from peak levels in 2004. Emissions from the industrial sector declined through 2009 but have remained relatively constant over the past few years. During the period from 2000 to 2013, California per capita GHG emissions continued to drop from a peak 14 MtCOze in 2001 to 12 MtCO,e in 2013. Common Build Alternative Element Impacts The proposed Project would be required to comply with AB 32 to achieve GHG emissions reduction targets from transportation sources (e.g., worker personal vehicles and maintenance vehicles—trucks, tractors, etc.) in 2020 and 2025 established by Executive Order B-16-2012 and a statewide emissions level reduction of 80 percent from 1990 levels by 2050 as established by Executive Order S-3-05, which would directly further reduce GHG emissions. In addition,SCAQMD Regulation XXVII Rules 2701&2702, City of La Palma Goals OS-4.4/4.6, City of Buena Park Goals CS-21 through 23, and the City of Anaheim General Plan establish voluntary programs to reduce GHGs within their jurisdictions. Because the GHG analysis considers GHG emissions from all project segments amortized over the lifetime of the project for each build alternative as a whole, rather than for each specific Project segment, there are no common elements to the impact analysis. However, neither build alternative would conflict with an applicable plan, policy,or regulation adopted for the purpose of reducing GHG emissions;therefore,the contribution to statewide emissions,which are trending downward for transportation sources,would be less than significant. Rehabilitation of Western Regional Sewers, Project 3-64 3-103 3.6-Greenhouse Gas Emissions Build Alternative 1 As shown in Table 3.6-1,GHG emissions for Build Alternative 1 would be below the SCAQMD thresholds for all proposed Project construction years. Compliance with the SCAQMD significance thresholds for GHGs would not trigger mandatory reporting of project emissions to CARB and demonstrates that the contribution to statewide emissions,which are trending downward for transportation sources,would be less than significant. Build Alternative 2 As shown in Table 3.6-1,GHG emissions for Build Alternative 2 would be below the SCAQMD thresholds for all proposed Project construction years. Compliance with the SCAQMD significance thresholds for GHGs would not trigger mandatory reporting of project emissions to CARB and demonstrates that the contribution to statewide emissions,which are trending downward for transportation sources,would be less than significant. 3.6.4.4 No Build Alternative Under the No Build Alternative, no rehabilitation or replacement of the Western Regional Sewers or improvements at the Westside Pump Station would occur other than routine operations and maintenance activities as discussed in Section 2.6. The No Build Alternative would not generate significant amounts of GHGs or conflict with any applicable, plan, policy, or regulation adopted for the purposes of reducing GHGs. 3.6.5 Mitigation Measures Construction and operation of the proposed Project would not result in significant GHG emission impacts that would require mitigation. In addition, as demonstrated in Sections 3.2.4.5 and 3.2.4.6 (AQ- 3j, project emissions of NO, a precursor to 03 which can contribute to the greenhouse gas effect, are below SCAQMD significance thresholds, do not result in a cumulatively considerable net increase in this pollutant, and do not conflict with or obstruct the implementation of the SCAQMD 2012 AQMP. Rehabilitation of Western Regional Sewers, Project 3-64 3-104 3.7-Hazards and Hazardous Materials 3.7 Hazards and Hazardous Materials This section describes the existing hazards and hazardous materials setting of the proposed Project and analyzes the proposed Project's impacts related to hazards and hazardous materials. Mitigation measures are identified as necessary to reduce or avoid significant impacts of the proposed Project. Information presented in the discussion and subsequent analysis is based on the Hazards Assessment in Appendix D. 3.7.1 Regulatory Setting 3.7.1.1 Federal Federal Toxic Substances Control Act and Resource Conservation and Recovery Act The federal Toxic Substances Control Act of 1976 (15 U.S.C. 2601-2697) and the Resource Conservation and Recovery Act (RCRA) of 1976 (42 United States Code [U.S.C.] 6901-6992) established a program administered by the United States (U.S.) Environmental Protection Agency (USEPA)for regulation of the generation,transportation,treatment,storage, and disposal of hazardous waste. RCRA was amended in 1984 by the Hazardous and Solid Waste Act (Public Law 98-616), which affirmed and extended the "cradle-to-grave' system of regulating hazardous wastes. The use of certain techniques for the disposal of some hazardous wastes was specifically prohibited by the Hazardous and Solid Waste Act. Under the authority of RCRA, the regulatory framework for managing hazardous waste, including requirements for entities that generate, store, transport, treat, and dispose of hazardous waste, is found in 40 Code of Federal Regulations, Parts 260-299. Hazardous Materials Transportation Act The U.S. Department of Transportation regulates hazardous materials transportation under Title 49 of the United States Code. State agencies with primary responsibility for enforcing federal and state regulations and responding to hazardous materials transportation emergencies are the California Highway Patrol and the California Department of Transportation (Caltrans). These agencies also govern permitting for hazardous materials transportation. Title 49 Code of Federal Regulations reflects laws passed by Congress as of January 2,2006. Comprehensive Environmental Response.Compensation.and Liability Act The Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA; 42 U.S.C. 9601-9675), commonly known as "Superfund," was enacted by Congress on December 11, 1980. This law provided broad federal authority to respond directly to releases or threatened releases of hazardous substances that may endanger public health or the environment. CERCLA established requirements concerning closed and abandoned hazardous waste sites, provided for liability of persons responsible for releases of hazardous waste at these sites, and established a trust fund to provide for cleanup when no responsible party could be identified. CERCLA also enabled the revision of the National Rehabilitation of Western Regional Sewers, Project 3-64 3-105 3.7-Hazards and Hazardous Materials Contingency Plan. The National Contingency Plan provided the guidelines and procedures needed to respond to releases and threatened releases of hazardous substances,pollutants, or contaminants. Superfund Amendments and Reauthorization Act of 1986 The Superfund Amendments and Reauthorization Act(SARA) (42 U.S.C.Section 9601 et seq.) established a nationwide emergency planning and response program and imposed reporting requirements for businesses that store, handle, or produce substantial quantities of extremely hazardous materials. SARA requires the states to implement a comprehensive system to inform local agencies and the public when a significant quantity of such materials is stored or handled at a facility. Additionally, SARA identifies requirements for planning, reporting,and notification concerning hazardous materials. USEPA maintains a database of sites that are included on the National Priorities List (NPL) (40 Code of Federal Regulations Part 300). The NPL is the list of national priorities among the known releases or threatened releases of hazardous substances, pollutants,or contaminants throughout the United States and its territories. Occupational Safety and Health Act The Occupational Safety and Health Act was passed by Congress in 1970 and is the primary federal law that governs occupational health and safety in the workplace. In part, it governs hazards in a working environment, such as exposure to toxic chemicals, excessive noise levels, mechanical dangers, heat or cold stress, or unsanitary conditions. Clean Water Act The Clean Water Act (33 U.S.C. Section 1251 et seq.) was enacted to restore and maintain the chemical, physical, and biological integrity of the nation's waters by regulating point and nonpoint pollution sources, providing assistance to publicly owned treatment works for the improvement of wastewater treatment, and maintaining the integrity of wetlands.This includes the creation of the National Pollutant Discharge Elimination System (NPDES),which requires states to establish discharge standards specific to waterbodies and regulates stormwater discharge from construction sites through the implementation of a stormwater pollution prevention plan (SWPPP). Spill Prevention.Control.and Countermeasure Rule The Federal Spill Prevention, Control, and Countermeasure Rule (40 Code of Federal Regulations Part 112)was enacted to require response and cleanup after a spill occurs and to prevent the discharge of oil into navigable waters of the United States or adjoining shorelines. Facilities subject to the rule must prepare and implement a plan called a spill prevention,control and countermeasure(SPCC) plan. Federal Response Plan The Federal Response Plan of 1999 (FEMA 1999) is a signed agreement among 27 federal departments and agencies, including the American Red Cross, that (1) provides the mechanism for coordinating the delivery of federal assistance and resources to augment efforts of state and local governments overwhelmed by a major disaster or emergency, (2) supports implementation of the Robert T. Stafford Rehabilitation of Western Regional Sewers, Project 3-64 3-106 3.7-Hazards and Hazardous Materials Disaster Relief and Emergency Act, as well as individual agency statutory authorities; and (3) supplements other federal emergency operations plans developed to address specific hazards. The Federal Response Plan is implemented in anticipation of a significant event likely to result in a need for federal assistance or in response to an actual event requiring federal assistance under a presidential declaration of a major disaster or emergency. 3.7•1.2 State California Government Code Section 65962.5 California Government Code Section 65962.5 requires the California Environmental Protection Agency to prepare an annual hazardous waste and substances list, commonly referred to as the Cortese List. Although the Cortese List is a state requirement, there are federal databases characterized as Cortese List databases. A review of federal,state, and local Cortese List databases identified a number of known and potentially contaminated sites within the Project area. California Occupational Safety and Health Administration The California Occupational Safety and Health Administration (Cal/OSHA) is the primary agency responsible for worker safety in the handling and use of chemicals in the workplace.Cal/OSHA standards are generally more stringent than federal regulations. The employer is required to monitor workers' exposure to listed hazardous substances and notify workers of exposure (8 California Code of Regulations 330 et sec.). The regulations specify requirements for employee training, availability of safety equipment,accident prevention programs, and hazardous substance exposure warnings. California Hazardous Waste Control Act The Department of Toxic Substances Control (DTSC) is responsible for the enforcement of the Hazardous Waste Control Act (California Health and Safety Code, Section 25100 et seq.), which creates the framework under which hazardous wastes are managed in California. The law provides for the development of a state hazardous waste program that administers and implements the provisions of the federal RCRA cradle-to-grave waste management system in California. It also provides for the designation of California-only hazardous waste and the development of standards that are equal to or, in some cases, more stringent than the federal requirements. While the Hazardous Waste Control Act is generally more stringent than RCRA, both the state and federal laws apply in California. The DTSC, one of six departments that comprise the California Environmental Protection Agency, is the primary agency in charge of enforcing both the federal and state hazardous materials laws in California. The Hazardous Waste Control Act lists 791 chemicals and approximately 300 common materials that may be hazardous; establishes criteria for identifying, packaging, and labeling hazardous wastes; prescribes management controls; establishes permit requirements for treatment, storage, disposal, and transportation;and identifies some wastes that cannot be disposed of in landfills. Rehabilitation of Western Regional Sewers, Project 3-64 3-107 3.7-Hazards and Hazardous Materials Hazardous waste is defined as waste that has the potential to be dangerous or harmful to human health or the environment. According to 22 California Code of Regulations 66261.2, waste is considered hazardous waste if it is on the RCRA hazardous waste list (F-list, K-list, P-list, or U-list) or exhibits characteristics of hazardous waste (ignitability, corrosivity, reactivity, or toxicity) or is used oil or mixed wastes. Other types of hazardous materials include radioactive and biohazardous materials. Radioactive materials and wastes contain radioisotopes, which are atoms with unstable nuclei that emit ionizing radiation to increase their stability. Radioactive waste mixed with chemical hazardous waste is referred to as "mixed wastes." Biohazardous materials and wastes include anything derived from living organisms. They may be contaminated with disease-causing agents, such as bacteria or viruses (22 California Code of Regulations 66261.1 et seq.). California Accidental Release Prevention Program Similar to the USEPA Risk Management Program, the California Accidental Release Prevention (CaIARP) Program (19 California Code of Regulations 2735.1 et seq.) regulates facilities that use or store regulated substances, such as toxic or flammable chemicals, in quantities that exceed established thresholds. The overall purpose of CaIARP is to prevent accidental releases of regulated substances and reduce the severity of releases that may occur. The CaIARP Program meets the requirements of the USEPA Risk Management Program,which was established pursuant to the Clean Air Act Amendments. California Hazardous Material Management Act In California, the handling and storage of hazardous materials is regulated by Division 20, Chapter 6.95, of the California Health and Safety Code (Section 25500 et seq.). Under Sections 25500-25543.3, facilities handling certain amounts of hazardous materials are required to prepare a hazardous materials business plan. Hazardous materials business plans contain basic information about the location, type, quantity, and health risks of hazardous materials stored,used,or disposed of in the facility. In the event that a facility stores quantities of specific acutely hazardous materials above the thresholds set forth by California code,facilities are also required to prepare a risk management plan and California accidental release prevention plan. The risk management plan and accidental release prevention plan provide information about the potential impact zone of a worst case release and require plans and programs designed to minimize the probability of a release and mitigate potential impacts. California Fire Code The California Fire Code (CFC) is Chapter 9 of Title 24 of the California Code of Regulations. It was created by the California Building Standards Commission, and it is based on the International Fire Code (IFC) created by the International Code Council (ICC). It is the primary means for authorizing and enforcing procedures and mechanisms to ensure the safe handling and storage of any substance that may pose a threat to public health and safety. The CFC regulates the use, handling, and storage Rehabilitation of Western Regional Sewers, Project 3-64 3-108 3.7-Hazards and Hazardous Materials requirements for hazardous materials at fixed facilities. The CFC and the California Building Code use a hazard classification system to determine what protective measures are required to protect fire and life safety. These measures may include construction standards, separations from property lines, and specialized equipment.To ensure that these safety measures are met,the CFC employs a permit system based on hazard classification.The CFC is updated every three years. California Emergency Services Act Under the Emergency Services Act (California Government Code, Section 8550 et seq.), the State of California developed an emergency response plan to coordinate emergency services provided by federal, state, and local agencies. Rapid response to incidents involving hazardous materials or hazardous waste is an integral part of the plan, which is administered by the Governor's Office of Emergency Services. The Office of Emergency Services coordinates the responses of other agencies, including the USEPA, California Highway Patrol, Regional Water Quality Control Boards (RWQCBs), air quality management districts,and county disaster response offices. Sanitary Sewer Overflow Reduction Program Sanitary sewer overflow (SSO) is the diversion of untreated or partially treated wastewater from a sanitary sewer system. SSOs have the potential to pollute surface and ground waters, which could threaten public health, affect aquatic life, and impair recreational use of surface waters. The State Water Resources Control Board (SWRCB) adopted statewide general Waste Discharge Requirements (WDRs) for sanitary sewer systems which require public agencies that own or operate sanitary sewer systems to develop and implement sewer system management plans and report all SSOs to the SWRCB. Hazardous Material Transport Hazardous waste transporters must comply with the California Vehicle Code, California Highway Patrol Regulations (California Code of Regulations Title 13); the California State Fire Marshall Regulation (California Code of Regulations Title 19); United States Department of Transportation Regulations, Title 49 Code of Federal Regulations; and the Health and Safety Code and California Code of Regulations,Title 22,which is administered by DTSC. 3.7.1.3 Local Integrated Emergency Response Program In accordance with Occupational Safety and Health Administration regulations, Orange County Sanitation District (OCSD) has implemented an integrated emergency response program (IERP)to cover worker safety, spill prevention, emergency response, and hazardous materials management. The IERP provides structural design specifications for storage tanks, including over-flow alarms and secondary containment volumes;visual monitoring schedules for aboveground storage tanks; underground storage tank tightness testing schedules; emergency response procedures; and reporting requirements. The IERP also includes safety procedures for operations and maintenance workers that include worker safety Rehabilitation of Western Regional Sewers, Project 3-64 3-109 3.7-Hazards and Hazardous Materials training, hazard communications, personal protective equipment, site security, and departmental organization. Furthermore, the IERP includes training in and implementation of the Incident Command System during crisis situations. Hazardous Materials and Business Emergency Plan Programs The Environmental Health Division of the Orange County Health Care Agency was designated as the Certified Unified Program Agency (CUPA) for Orange County. The CUPA is the local administrative agency that coordinates the regulation of hazardous materials and hazardous wastes in Orange County through six programs: hazardous materials disclosure, business emergency plan, hazardous waste, underground storage tank, aboveground petroleum storage tank, and California Accidental Release Prevention(CalARP). South Coast Air Quality Management District Rule 1166 The purpose of SCAQMD Rule 1166 is to limit volatile organic compound (VOC) emissions from wastewater systems and not to emit greater than 500 parts per million (ppm) above background levels. The facility operator would need to comply with all appropriate sections of the rule and submit detailed plans identifying the location of the facility and all associated components of the wastewater system. 3.9.2 Existing Conditions 3.7.2.1 Hazardous Materials Based on results of the regulatory database review, the potential for hazardous materials may exist within the Project area or on properties adjacent to the Project area at facilities that generate, store, and dispose of these substances or at the location of past releases of these substances. Examples of hazardous material sites adjacent to the project include many industrial sites with known or potential soil and/or groundwater contamination. Other potential sources of hazardous material adjacent to the Project area include leaking underground storage tanks, surface runoff from contaminated sites, and migration of contaminated groundwater plumes. The potential hazardous materials on or adjacent to the proposed Project area include petroleum hydrocarbons (e.g.,gasoline and diesel fuels), dry-cleaning solvents, asbestos, lead-based paint, and heavy metals, which could be harmful to human health and the environment.These materials are regulated by federal,state,and local agencies. California Government Code Section 65962.5 requires the California Environmental Protection Agency to prepare an annual hazardous waste and substances site list,commonly referred to as the Cortese List. Federal, state, and local databases were reviewed to evaluate potential hazardous material concerns in the proposed Project area. A detailed discussion of relevant sites appears below in Section 3.7.2.2 (See also Appendix D—Hazardous Materials Technical Memo). Rehabilitation of Western Regional Sewers, Project 3-64 3-110 3.7-Hazards and Hazardous Materials 3.7.2.2 Regulatory Database Reoiew In addition to the Envirosite Report discussed below,file review requests were submitted to Cal-Recycle, the Orange County Health Care Agency (OCHCA), and the RWQCB, depending on the lead agency responsible for ensuring cleanup of affected soil and or groundwater.The OCHCA is under contract from the State Water Resources Control Board to administer a Local Oversight Program for the cleanup of leaking underground storage tanks (USTs)for all the cities and unincorporated areas of Orange County, except for the Cities of Anaheim, Fullerton,and Santa Ana. The RWQCB oversees the site cleanup program for activities at non-UST sites where soil or groundwater contamination have occurred. Many of these sites are former industrial facilities and dry cleaners where chlorinated solvents were spilled or have leaked into the soil or groundwater. Cal-Recycle is responsible for the permitting and closure of landfills. Additional site information from these agencies is discussed below as applicable. Envirosite The proposed Project Area includes four pipelines and a pump station: the Orange Western Sub-trunk, the Westside Relief Interceptor, the Los Alamitos Sub-trunk, the Seal Beach Blvd. Interceptor, and the Westside Pump Station. Per the American Society for Testing and Materials (ASTM) 1527-13 standard, the search of government records reports for potential listed sites up to 1 mile from the proposed Project Area was conducted. Due to the length of the pipelines (up to 2 to 3 miles) and the location of each, three separate government records reports were obtained from Envirosite Corporation. Two reports were obtained that listed 330 and 445 sites, respectively, within the ASTM 1527-13 standard search radius of up to 1 mile from the Westside Relief Interceptor,the Los Alamitos Sub-trunk, the Seal Beach Blvd. Interceptor, and the Westside Pump Station. Some sites overlap and are listed in multiple reports. One report was obtained for the Orange-Western Sub-trunk that listed 200 sites within the ASTM 1527-13 standard search radius of up to 1 mile. Although numerous sites are listed within each report, the number of actual listed sites is lower since the same site could be listed in several different databases. For example, a service station could be listed in both the underground storage tank and leaking underground storage databases.Table 3.7-1 summarizes all listed sites identified within 1 mile of the proposed Project area. Rehabilitation of Western Regional Sewers, Project 3-64 3-111 3.7-Hazards and Hazardous Materials Figure 3.7-1 through Figure 3.7-12 show all sites within 0.25 mile of the proposed Project area.

The depth of open-trench construction is anticipated to range from approximately 13 feet to 31 feet. Therefore, only sites within 0.25 mile of the proposed Project were evaluated further and discussed in detail in the Hazards Assessment Memorandum (Appendix D). On this basis, all sites within 0.25 mile of the proposed Project area with potential hazardous material concerns are discussed below. All other sites beyond 0.25 mile with potential hazardous material concerns are not likely to impact the proposed Project since potential contamination plumes would likely dissipate over time and not migrate off site at that distance. Orange-Western Sub-trunk Listed Sites The state and County databases list 28 sites within the vicinity of the proposed Project as having aboveground storage tanks (ASTs) and USTs. No violations or active violations for these sites have been reported. In addition, any acquisition of these sites that would require removal of storage tanks is not anticipated as a part of the proposed Project. However, nine sites, which are listed in the Hazards Assessment Memorandum (Appendix D),are adjacent to the proposed improvements. Westside Relief Interceptor, Los Alamitos Sub-trunk,Seal Beach Blvd. Interceptor, and Westside Pump Station Listed Sites and Unmappable Sites Corrective Action (CORRACTS) Two sites are listed in the CORRACTS database (Safety Kleen is listed twice). The corrective action database is used to investigate and remediate hazardous releases. Safety Keen Corporation —This facility is located at 3876 Florista Street, approximately 500 feet north from the Westside Relief Interceptor. The Los Alamitos Medical Center currently owns the site and is located in the northwest corner of the intersection of Katella Avenue and Bloomfield Street. The facility consists of a hospital, various medical arts buildings, a physical plant, and several asphalt parking lots. Although no documented spills have been reported for this site, previous investigations indicate soil and groundwater has been impacted by releases from historic operations on site. Shallow groundwater was observed on site approximately 10 feet below ground surface (bgs) and flows in a southwesterly direction. Site assessment results indicated hazards for on-site workers do not exceed health risk Rehabilitation of Western Regional Sewers, Project 3-64 3-114 3.7-Hazards and Hazardous Materials thresholds. Therefore, no further active remediation was recommended; however, DTSC has not officially closed the active cases on this site. Naval Weapons Station Seal Beach —This facility is located southeast of Seal Beach Boulevard and Westminster Avenue and includes approximately 5,000 acres of land. A portion of the site is located adjacent to the Seal Beach Blvd. Interceptor. The Naval Weapons Station Seal Beach is a weapons and ammunition storage, disbursing, and reconditioning base for the United States Navy. Past operations at the station have included aerospace manufacturing/maintenance, fire training areas, firing range, landfill for construction, oil/water separators, open burn/open detonation, weapons research, and industrial treatment facility that have contributed to contamination on site. Numerous investigations have been conducted on the site, which have identified the following contaminants: acids, alkalines, explosives, waste oils, polychlorinated biphenyls (PCBs), fuels, solvents, paint thinners, asbestos, mercury, volatile organic compounds (VOCs), heavy metals, oil drilling fluids, and paint wastes. Due to the size of the site and the numerous areas that contain contamination, the site was divided into separate operating units (OUs). A portion of this site (labeled as IR Site 70) located within OUB, is approximately 40 acres; however, the contamination plume extends beyond the site boundaries. The site is known as the Research, Testing, and Evaluation area, consisting of multistory office and production buildings, asphalt-paved parking area, an assortment of aboveground tanks and attendant above and belowground piping distribution systems, and several concrete-lined sumps. The groundwater flow is generally to the southeast with relatively low gradients, consistent with historical data, and away from the proposed Project. Concentrations on site are relatively stable, with some samples decreasing and others increasing. The site is active and has been undergoing groundwater monitoring.A site feasibility study is scheduled to be completed in 2016. Leaking Underground Storage Tank(LUST) Eighty sites are listed in the Leaking Underground Storage Tank (LUST) databases. Of the 80 sites listed in the LUST databases, 30 are open with active remedial activities and are discussed below. The other sites have been closed with No Further Action (NFA)granted by the lead agency. John Phu & Vivian Lam — This facility is located at 22429 South Bloomfield Avenue, in the northwest quadrant of the intersection with Bloomfield Avenue and Orange Avenue and adjacent to the Los Alamitos Sub-trunk. This site is currently occupied by a liquor store. According to the 2003 tank closure report, a hole was observed in the bottom of the tanks during tank removal. Based on field observations at that time, it is likely an unauthorized release of petroleum occurred on site. Discoloration of soil was noted in the western portion of the site where the former USTs were located. Soil samples indicated a high concentration of benzene. Groundwater contamination was not confirmed. Additional subsurface investigation was recommended, including possible groundwater sampling. Former Mercury Rentals Inc. — This facility is located at 4664 Lincoln Avenue (south side of Lincoln Avenue) less than 0.25 mile east from the Los Alamitos Sub-trunk off Denni Street and approximately 0.25 mile west from the Westside Relief Interceptor off Moody Street. During the early 1960s, Top Oil Rehabilitation of Western Regional Sewers, Project 3-64 3-115 3.7-Hazards and Hazardous Materials Station occupied this site and was closed in 1964.The site was then occupied by Mercury Rentals facility in the mid-1960s. Six USTs were historically present on site and stored diesel fuel, gasoline, and possibly motor oil. Motor oil may also have been stored in ASTs on site. The presence of free product and product plume that exceeds 100 feet in length was detected during site monitoring. On site, the depth to groundwater ranges from 7 feet to 30 feet with a shallow historic groundwater flow direction to the north to northeast, towards the proposed Project. Remediation is ongoing including a Phase II of the revised vapor intrusion Work Plan to remove residual contaminants on site. Hyatt Die Cast and Engineering —This facility is located at 4656 Lincoln Avenue (south side of Lincoln Avenue) less than 0.25 mile east from the Los Alamitos Sub-trunk off Denni Street and approximately 0.25 mile west from the Westside Relief Interceptor off Moody Street. In 1966, Hyatt Die Cast and Engineering operated on site to provide die castings for aerospace, electronics, and commercial applications.Two USTs were used to store diesel and gasoline for delivery trucks. In 1992,the USTs were removed; and samples were collected which identified contamination around the tanks. In 1993, monitoring of the site was initiated to determine the extent of the contamination on site.The depth to groundwater on site ranges from approximately 4.5 feet to 7 feet with the groundwater flow direction primarily to the southwest, toward the proposed Project. Elevated concentrations in the groundwater samples are still present,and monitoring of the site is ongoing. Parking lot (Former Shell Service Station/Shell Oil) — This facility is located at 4001 Ball Road, east of Bloomfield Street and adjacent to the Los Alamitos Sub-trunk, and is listed in the LUST database. In 1986, an unauthorized release was reported following removal of four USTs. Remedial activities and monitoring of the site began shortly after the release was identified.The petroleum release affected the soil and shallow groundwater. In 1999,the existing service station, including the USTs,dispenser islands, and product piping, were removed from the site. The site has been redeveloped and is currently a parking lot for a local grocery store. Hydrocarbons were detected in the soil and groundwater at the Goodyear Tire Center east of this site. In addition, the property to the west was a historic service station; and the property to the south is an existing service station. Concentrations of benzene were detected in groundwater samples on the west side of the site. Landfill debris was also found in the subsurface along the western half of the site. The debris was observed during monitoring well installation but not during UST removal. The debris was found at depths ranging from 2 feet to 12 feet and was approximately 4 feet thick. The extent of the debris is unknown. Landfill debris was also found on the Goodyear Tire site during removal of a tank. Groundwater flow direction is primarily to the west, toward the proposed Project, with an average groundwater elevation of approximately 19 feet. The historic monitoring data indicates that the concentrations in the samples are generally stable or decreasing over time. 76 #5792 (Former Tosco) — This facility is located at 4002 Ball Road, east of Bloomfield Street and adjacent to the Los Alamitos Sub-trunk. This site is listed in the LUST database as having two in-service USTs used to store gasoline, one in-service AST of propane, and one in-service AST of waste oil. Petroleum constituents were discovered during the removal and replacement of USTs in 1997. Remedial Rehabilitation of Western Regional Sewers, Project 3-64 3-116 3.7-Hazards and Hazardous Materials activities have been conducted on the site. The average depth to groundwater is approximately 9 feet, with a groundwater flow direction toward the southwest, toward the proposed Project. In December 2015,the SWRCB closed the case. Circle K Store #2211205 (Former Mobil #18-GOT/Seal Beach Mobil Mart) — This facility is located at 12240 Seal Beach, north of Rossmoor Center Way, east of Seal Beach Boulevard, and adjacent to the Westside Relief Interceptor and the Los Alamitos Sub-trunk. Three in-service USTs are used to store gasoline, one in-service UST is used to store diesel, and one in-service AST stores propane. In 2001 facility upgrade activities were performed, and an unauthorized release was reported. Groundwater monitoring wells were installed and monitored. The depth to groundwater ranges from approximately 13 feet to 14.5 feet with a groundwater flow direction to the southwest,toward the proposed Project. Concentrations are above Low Threat Closure Policy criteria in groundwater west of the site.A remedial action plan was prepared to address the off-site contamination. Monitoring is ongoing at this site. Rossmoor Car Wash — This facility is located at 11031 Los Alamitos in the southwest corner of the intersection with Katella Avenue and Los Alamitos Boulevard and adjacent to the Los Alamitos Sub-trunk and the Westside Relief Interceptor. An unauthorized release was reported in 1991; however, three USTs were not removed until 2003. Site assessments and preliminary remedial activities have been conducted on the site.The depth to groundwater ranges from approximately 10.5 feet to 13.5 feet; and the groundwater flow is to the southeast, toward the Los Alamitos Sub-trunk and the Westside Relief Interceptor. The northeastern portion of the property has been identified as the area of hydrocarbon- impacted groundwater. A drinking water well is located within 2,000 feet of the site near Cherry Street and Catalina Street. Monitoring of the site is ongoing. Shell Oil — This facility is located at 10961 Los Alamitos Boulevard in the northwest corner of the intersection with Katella Avenue and Los Alamitos Boulevard and adjacent to the Los Alamitos Sub-trunk and the Westside Relief Interceptor. Three in-service USTs are registered on site. In 2001, collection of groundwater and soil samples detected petroleum constituents 21 feet bgs. Monitoring and remedial activities have been conducted on the site. Groundwater flow direction is generally to the southeast, toward the proposed Project. Groundwater beneath the site was encountered at an average depth of 14 feet. Since 2011, the groundwater plume has been stable or decreasing. No public supply wells or surface waterbodies are within 1,000 feet of the site.Any residual petroleum constituents would pose a low risk to human health, safety, and the environment. The SWRCB granted case closure in September 2015. Circle K Store#2211150(Former Mobil#IS-GQO)—This facility is located at 3971 Cerritos Avenue in the northwest quadrant of Cerritos Avenue and Bloomfield Street and adjacent to the Los Alamitos Sub- trunk. Two in-service USTs are used to store gasoline, and one in-service UST is used to store waste oil. Three USTs that stored gasoline were removed in 2000. Site assessments have been conducted since 2000 and have identified the primary source area of contamination near the former USTs in the southern portion of the site. Depth to groundwater on site ranges from approximately 8.5 feet to Rehabilitation of Western Regional Sewers, Project 3-64 3-117 3.7-Hazards and Hazardous Materials 10.5 feet with a groundwater flow direction generally to the southwest, toward the proposed Project. Per the low-threat closure review by Orange County Local Oversight Program, on-site groundwater sampling is ongoing. Unocal#4686(aka Tosco/76)/Russell Conkle Unocal#4686—This facility is located at 12071 Seal Beach Boulevard in the southwest quadrant of Bradbury Road and Seal Beach Boulevard and adjacent to the Los Alamitos Sub-trunk and the Westside Relief Interceptor. Two in-service USTs store gasoline, one in- service UST stores diesel, and one in-service UST stores waste oil. In 1997, site monitoring identified the presence of fuel hydrocarbons in the soil. In 1998, remedial activities and monitoring began on site.The source areas of concern are located near the current USTs and the dispenser islands. Surface bodies of water and water production wells are located over 2,000 feet away from the site. The average groundwater elevation beneath the site was approximately 4.5 feet; and the estimated groundwater flow direction is to the east, toward the proposed Project. Monitoring of the site is ongoing to confirm residual contamination is stable and/or decreasing overtime. Response—CA Two sites are listed in the Response — CA database (Joint Forces Training Base is listed twice). This database contains California response sites with a confirmed release of hazardous materials. The Joint Forces Training Base is discussed below, and the Naval Weapons Station Seal Beach was previously discussed above. Joint Forces Training Base—This facility is located near the intersection of Lexington Drive and Farquhar Avenue,approximately 0.25 mile east of the Westside Relief Interceptor and the Los Alamitos Sub-trunk off Los Alamitos Boulevard and approximately 0.25 mile south of the Westside Relief Interceptor off Katella Avenue. This site includes approximately 1,300 acres of relatively flat terrain. The facility is operated by the California Army National Guard (CA AIRING) and is the coordinating center for the Governor's Office of Emergency Services and is a disaster support site. A preliminary assessment was conducted in 1993 which lead to monitoring and remediation on the site. Groundwater contamination was identified in several areas of the site including the JP-4 Tank Farm; Fuel Farm Office; New Crash Fire Rescue Training Area; Seabee Compound; Hangar 1; Hangar 2/Building 9; and Buildings 34, 35, 158,and 159. In addition, between the mid-1950s through 1988,the site accumulated landfill waste and in 2008 was transferred to a waste consolidation cell. The Four Seasons Gas Station in the northern portion of the site was in operation since the early 1950s. Three USTs were removed in 1996, and two additional tanks were removed in 2009. Several site investigations of this area identified elevated levels of total petroleum hydrocarbons as gasoline (TPH-g), benzene, and methyl tert butyl ether (MTBE) in the soil and groundwater samples. According to the 2015 groundwater monitoring report, groundwater monitoring on the site has identified groundwater depth ranging from 6 feet to 17 feet bgs; and the groundwater flow direction is to the southwest,toward the proposed Project. Monitoring and remedial activities are being conducted on the site in several areas due to past activities. Although contaminant Rehabilitation of Western Regional Sewers, Project 3-64 3-118 3.7-Hazards and Hazardous Materials levels in most areas continue to decrease, no further action has been granted for the Fuel Farm Office, Building 35 Wells, Buildings 158 and 159, and Hangar 1. Ten sites are listed as Certified Cleanup, No Further Action or otherwise listed in Permitting Databases. These sites are listed as having completed cleanup activities on site, no further action required,or listed as a permitted facility. Therefore,these sites would not impact the proposed Project. Of these 10 sites, one site is listed four times in another database with action required as follows: Los Alamitos Elementary School — This facility is located at 10862 Bloomfield Street, approximately 400 feet north of the Westside Relief Interceptor. From at least 1930 to 1950, the site was used for agricultural purposes with potential use of pesticides. From 1950 to 1980 the site operated as a railroad line with potential use of arsenic to treat railroad ties. The site has operated as a school since 1980: McAuliffe Intermediate School to the north and Los Alamitos Elementary School to the south. A historic railroad easement approximately 100 feet by 800 feet is between the two schools.According to the site screening in 2009, a preliminary environmental assessment conducted on site revealed the presence of elevated levels of arsenic in the shallow soils in the vicinity of the historic railroad line. Pesticides were also detected.The depth to groundwater on site ranges from 8 feet to 12 feet bgs, and the groundwater flows in a southwesterly direction, toward the proposed Project Area. Further investigation was conducted to delineate the extent of arsenic contamination on site. The impacted soil has not been removed from the site. SLIC Reg 8 Six sites are listed in the SLIC Reg 8 database.This database contains sites in the region 8 GeoTracker site cleanup program.The following two are listed as active open sites: Rossmoor Center(Former Goodyear Waste Dumpster Area)—This facility is located at 12239 Seal Beach Boulevard adjacent to the proposed Project. The Goodyear Tire Store occupied the site between 1994 and June 2004. Waste materials were stored in a dumpster area located south of the former building and west of the Parasol building, which was occupied by a restaurant.This area was also used for work on cars and to store containers of waste materials. The pavement in this area was reported to be degraded. The Goodyear building was demolished in 2006, and the property was redeveloped. Groundwater was encountered at 23 feet bgs. A water sample was collected that showed high concentrations of benzene, toluene, ethylbenzene, xylene, 1,2-dichloroethane (1,2-DCA), and naphthalene. MTBE or other oxygenate compounds were not detected in the groundwater sample. No VOCs were detected in the soil vapor sample.There has been no record of USTs on site,thus the source and/or approximate date of release of these hydrocarbons remains unknown. Remedial activities were performed on site from 2006 to 2012 which included excavation and off-site disposal. Soil was excavated to a depth of 20 to 22 feet to remove contaminated soil. Very moist soil was encountered at 18 feet bgs.The excavation could not be extended beyond 22 feet bgs due to slumping and caving of the moist, sandy soil. Approximately 567 cubic yards of soil was removed from the excavation. The excavated soils were transported off site.Groundwater was detected at approximately 12 to 14 feet bgs. Rehabilitation of Western Regional Sewers, Project 3-64 3-119 3.7-Hazards and Hazardous Materials Although the site is relatively flat,there are local variations in the groundwater flow and gradient in this area. Groundwater flow on the adjacent property to the east (Mobil) was measured in a southwest direction, toward the Los Alamitos Sub-trunk and the Westside Relief Interceptor; however, the groundwater flow in the upper zone on site is toward the northwest to southeast.According to the 2015 closure report and based on monitoring of the site after remediation, residual contaminants remain on site but are stable and should not impact deeper usable groundwater or human health. The remaining impacts are anticipated to degrade through natural attenuation; however, the RWQCB requested a Work Plan for additional soil sampling,groundwater plume delineation, and cleanup goals. Best Cleaners—This facility is located at 11139 Los Alamitos Boulevard adjacent to the proposed Project and within a commercial shopping center situated immediately southwest of the intersection of Los Alamitos Boulevard and Katella Avenue. Best Cleaners currently occupies this site as a dry cleaning facility that has clothing, cleaning, drying, and pressing equipment on site. Past uses of the site included agricultural use from the 1940s to late 1950s, part of a commercial shopping center in the late 1960s, and a dry cleaning facility since 1995. Tetrachloroethene (PCE) is the main product associated with dry cleaning processes. Since 2008, the facility has been using a petroleum-based solvent. The concerns on site are the presence of PCE and its breakdown products, which may pose a threat to groundwater quality. Sampling results concluded that the source of the contaminants was a former dry cleaning machine. The highest concentrations of contaminants were located adjacent to the machine. PCE- impacted soil migrated up to 40 feet from the former dry cleaning machine and to a depth of 22 feet beneath and immediately adjacent to the western portion of the dry cleaning facility. PCE-impacted groundwater has not migrated off site. According to the 2015 groundwater report, groundwater elevations have decreased; and the flow remains in an easterly direction,toward the proposed Project. Water was detected at approximately 13 feet bgs. According to the soil vapor survey and health risk assessment report,additional soil vapor samples were collected from the residential apartment complex to the west to determine if impacted soil vapors were a threat to the residents. The results concluded these potential containments were not considered a threat to the health of the residents of the apartment complex; however, due to contaminants still present beneath the dry cleaning facility, the RWQCB recommended a remedial action plan for the site. Following construction of a vapor extraction system and associated testing,a formal report will be submitted and closure of the site proposed. Aboveground and Underground Storage Tanks Ninety-nine sites are listed in state and county aboveground and underground storage tanks database. The state and county aboveground storage tanks (ASTs) and underground storage tanks (USTs) databases contain 99 listed sites. No violations or active violations have been reported for these sites. In addition, any acquisition of these sites that would require removal of storage tanks is not anticipated. However, 25 sites which are listed in the Hazards Assessment Memorandum (Appendix D) are adjacent to the proposed improvements. Rehabilitation of Western Regional Sewers, Project 3-64 3-120 3.7-Hazards and Hazardous Materials Unmappable Sites Fifty-eight sites are unmappable sites. The Envirosite government records report identified 58 sites as unmappable due to limited address information. These sites are discussed in further detail in the Hazards Assessment Memorandum (Appendix D). The majority of these sites were unmappable due to the owner address being searched instead of the facility address. One site is listed in the SLIC REG 4 CA database and discussed below.This database contains sites in the region 4 GeoTracker site cleanup program. Texaco USA-Bryant Lease—This facility is located at 7000 Pacific Coast Highway, approximately 0.25 mile west of the Seal Beach Blvd. Interceptor.The site case is open but has been designated as inactive since 1965 by the Department of Conservation, Division of Oil,Gas and Geothermal Resources. Oil, gas, and related well records were searched from the Department of Conservation, Division of Oil, Gas, and Geothermal Resources (DOGGR). According to DOGGR, three wells within approximately 700 feet to 1,000 feet from the proposed Project were identified as inactive and plugged; and one well within approximately 1,700 feet from the proposed Project was identified as active and plugged (see Appendix D). Although wells were identified within the proposed Project area, it is not likely that these wells would have impacted the Project area during installation. Nonetheless,during subsurface activities within the vicinity of the wells, construction personnel should still take precaution in the unlikely event that potentially stained soil or oil field debris is encountered. Historical Aerial and Topographic Photography Review In addition to the government records report, historic topographic and aerial photographs were obtained from Envirosite and reviewed for the proposed Project. A total of 46 topographic photographs dated from 1896 to 2015 and 36 aerial photographs dated from 1972 to 2014 were reviewed. During the early 1900s, the proposed Project area consisted mostly of the railroad, agricultural uses, and minor development. The Texas Oil Tank Farm located north of Ball Road and west of Moody Street was in operation during the 1930s. South of Cerritos Avenue, a railroad station appears visible on the 1935 topographic maps; it is later labeled as "stacks" on the 1949 topographic maps. Commercial and residential development started to increase during the 1940s, including the Naval Reservation which later became the Los Alamitos Naval Air Station in the early 1960s. In addition, power plants were constructed in the early 1960s in the Seal Beach area. Sanborn coverage was not available within the proposed Project area. Emergency Action Plans Orange County Hazardous Material Plan The County of Orange Health Care Agency is responsible for the Hazardous Materials Area Plan and is in part designed to address county wide emergencies and coordination of other agencies. This plan details Rehabilitation of Western Regional Sewers, Project 3-64 3-121 3.7-Hazards and Hazardous Materials Orange County Fire Authority's roles and responsibilities for Hazardous Materials spills, releases and unauthorized discharges. Orange County Emergency Operations Center The Orange County Emergency Operations Center (EOC) functions as the communication and coordination center for the County and operational area members and assists in communication and coordination between mutual aid coordinators and the state Office of Emergency Services during a county-wide or state-wide emergency response and recovery operation. The EOC is responsible for implementing emergency preparedness and emergency management or disaster management functions in an emergency situation. The EOC assures central coordination and support activities such as public official alerting, care and shelter, evacuation, search and rescue, resource mobilization, and recovery operations. City of Anaheim Emergency Operation Plan The Emergency Management and Preparedness section within the City of Anaheim is a support service that is responsible for the management and oversight of the City's EOC, disaster preparedness, grants, homeland security, and Orange County intelligence assessment center and hazard mitigation plan as well as the community emergency response team (CERT) volunteer program and radio amateur civil emergency services (RACES) volunteer program. This section ensures City employees and residents are prepared as much as possible for disasters by providing education in preparedness to employees and citizens;training employees in disaster response, management,and recovery; and maintaining the City's Emergency Operation Plan(EOP)and Hazard Mitigation Plan. 3.7.3 Thresholds of Significance The following significance criteria are based on Appendix G of the California Environmental Quality Act (CEQA) Guidelines (14 California Code of Regulations 15000 et seq.) and are used to evaluate potential for significant proposed Project impacts related to hazards and hazardous materials. Project impacts on hazards and hazardous materials would be significant if the proposed Project would: HAZ-1: Emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within 0.25 mile of an existing or proposed school HAZ-2: Be located on a site which is included on a list of hazardous materials sites compiled pursuant to Government Code Section 65962.5; and,as a result,would it create a significant hazard to the public or the environment HAZ-3: Impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan Other impact significance criteria for Hazards and Hazardous Materials identified in Appendix G of the CEQA Checklist have been evaluated previously in Section 4.8 of the Initial Study (See Appendix A) for the proposed Project. This previous evaluation determined that the proposed Project would result in Rehabilitation of Western Regional Sewers, Project 3-64 3-122 3.7-Hazards and Hazardous Materials either no impact or in less than significant impacts from hazards and hazardous materials under these criteria.As a result,the following impact significance criteria have not been evaluated further within this Environmental Impact Report(EIR): • Create a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials? • Create a significant hazard to the public or the environment through reasonably foreseeable upset and accident conditions involving the release of hazardous materials into the environment? • For a project within the vicinity of a private airstrip, would the project result in a safety hazard for people residing or working in the project area? • Expose people or structures to a significant risk of loss, injury, or death involving wildland fires, including where wildlands are adjacent to urbanized areas or where residences are intermixed with wildlands? 3.7.4 Impact Analysis Common Build Alternative Element Impacts Minor excavation would be required for the Orange-Western Sub-trunk and the Seal Beach Blvd. Interceptor pipelines using trenchless cured-in-place pipe (CIPP) methods(see section 2.5.3). In addition, minor excavation would be required for manhole replacement/rehabilitation and on all Project segments where exit/entry pits are required (see Chapter 2.0 for discussion of alternative construction methods)and for the improvements at the Westside Pump Station. Construction equipment and materials would be held in staging areas in parking lots, vacant lots, or segments of street lanes that are temporarily closed to minimize hauling distances and long-term disruption. Pavement and excavated soil and pipes would be hauled off site and disposed of in accordance with applicable state and local regulations in accordance with the ECMs described in Table 2.10-1. Trenches to accommodate the new pipe would be up to 7 feet wide. The construction area associated with replacement would be up to 1,000 feet long and 25 feet wide. Build Alternative 1 Impacts associated with the construction of Build Alternative 1 would have the potential to result in temporary, short-term impacts primarily due to the potential to encounter hazardous materials in soil and groundwater. This potential arises, in particular, from excavation and dewatering activities near sites along the replacement portions of the Los Alamitos Sub-trunk and the Westside Relief Interceptor pipelines where active remediation occurs or where the proposed Project is adjacent to sites that use Rehabilitation of Western Regional Sewers, Project 3-64 3-123 3.7-Hazards and Hazardous Materials hazardous materials (see Figure 3.7-1 through Figure 3.7-12). The proposed Project would require excavation for installation of new 21-to 39-inch pipes at depths of up to 22.7 feet bgs. Build Alternative 1 would have a greater potential of encountering hazardous materials in soil and groundwater along portions of the Westside Relief Interceptor compared to Build Alternative 2, since excavation and dewatering activities are proposed in this segment with construction of this alternative. Build Alternative 2 Impacts associated with the construction of Build Alternative 2 would be similar to impacts discussed above for Build Alternative 1 along portions of the Los Alamitos Sub-trunk. However, excavation and dewatering activities are proposed along the entire Los Alamitos Sub-trunk with this alternative, resulting in a greater potential of encountering hazardous materials in this segment where active remediation occurs or where the proposed Project is adjacent to sites that use hazardous materials(see Rehabilitation of Western Regional Sewers, Project 3-64 3-124 3.7-Hazards and Hazardous Materials Figure 3.7-1 through Figure 3.7-12).The construction of Build Alternative 2 would require excavation for installation of new 21-to 39-inch pipes at depths of up to 31.3 feet bgs. HAZ-1: Emit hazardous emissions or handle hazardous or acutely hazardous materials, substances,or waste within 0.25 mile of an existing or proposed school? The proposed Project is located within a dense urban area of Orange County.Table 3.7-2 lists 23 schools located within 0.25 mile of the proposed Project area.

"Acutely' hazardous wastes are identified by USEPA in 40 Code of Federal Regulation Section 261.33. No acutely hazardous waste is anticipated to be emitted or used during construction. The common hazardous Rehabilitation of Western Regional Sewers, Project 3-64 3-125 3.7-Hazards and Hazardous Materials materials (fossil fuels, lubricants, solvents, resins) emitted and used during the construction activities would occur with construction of either Build Alternative 1 or 2. The contractors are responsible for accident prevention, containment, and spill response. The hazardous materials used for the proposed Project would be handled in accordance with federal, state, and local laws, which ensure the safe transport, use, storage, and disposal. In addition, any hazardous material emissions would be reduced through control measures in accordance with federal, state, and local laws. Therefore, temporary construction impacts associated with hazardous emissions and handling of hazardous waste would be less than significant for both Build Alternatives 1 and 2. 3.7.4.2 Operational Impacts The operation of either of the build alternatives would be the same as existing operations consisting of maintenance of the pipelines and odor control. Operations of the Western Regional Sewers require use of chemicals including, but not limited to, magnesium hydroxide, hydrogen peroxide,sodium hydroxide, and ferrous chloride to control odor and corrosion. These chemicals would be transported throughout the proposed Project area. The transportation of these chemicals is regulated by federal and state law. OCSD, therefore, cannot regulate the transportation of these chemicals. The transport and use of the chemicals would be completed in accordance with labeling and all state and federal laws and regulations regarding the transport and use of hazardous materials. No complaints by the schools adjacent to the proposed Project area regarding the existing operations are known.The operational impacts associated with the emissions or handling of hazardous waste on the schools within 0.25 mile of the proposed Project would therefore be less than significant. HAI-2: Be located on a site which is included on a list of hazardous materials sites compiled pursuant to Government Code Section 65962.5; and, as a result, would it create a significant hazard to the public or the environment? 3.7.4.3 Construction Impacts Common Build Alternative Element Impacts According to California Government Code Section 65962.5 (Cortese List), one site on this list, the Naval Weapons Station Seal Beach, is located southeast of the intersection of Seal Beach Boulevard and Westminster Avenue and adjacent to the Seal Beach Blvd. Interceptor. This site was discussed in detail in Section 3.7.2.Also discussed in Section 3.7.2 are the 17 sites associated with the release of hazardous materials. Proposed excavation and/or dewatering activities adjacent to these sites could create a significant hazard to the public or the environment since remedial activities are ongoing. Several sites were also discussed in Section 3.7.2.2 with shallow groundwater contamination located upgradient and flowing toward the Project areas where replacement activities would occur and where excavation for Build Alternatives 1 and 2 could be up to 22.7 feet bgs and 31.3 feet bgs, respectively. As a result, the construction activities may encounter contaminated groundwater and soils requiring special materials handling,disposal,and appropriate personnel protection equipment to protect against worker exposure. Additionally, the presence of VOCs introduces additional worker safety concerns Rehabilitation of Western Regional Sewers, Project 3-64 3-126 3.7-Hazards and Hazardous Materials through the vapor intrusion/inhalation pathway. Excavation and dewatering near these sites adjacent to replacement areas could be a significant hazard to the public or environment because of the possible presence of contaminated groundwater and/or soil. Mitigation measures are required, and impacts would be less than significant with implementation of mitigation measure HAZ MM 1. As described in Chapter 2.0, Section 2.10 Environmental Control Measures, all work activities will be conducted to be consistent with Cal/OSHA regulations for safety, including those outlined in California Code of Regulations, Title 8, Section 1540, Excavations; and the proposed Project would have less than significant impacts on worker safety. 3.7.4.4 Operational impacts The operations for both build alternatives would be similar to existing conditions as discussed above and consist of trips within the Project area to complete routine maintenance; clean sewer lines and manholes; perform visual inspection utilizing closed-circuit television and camera inspection; conduct flow-monitoring, as-needed repairs, and chemical dosing for odor and corrosion control; and operate the air scrubber if it is selected for the proposed Project. The operation of the Project would not be impacted by sites on the Cortese List, and impacts for the build alternatives would be less than significant. NAZ-3: Impair Implementation of or physically Interfere with an adopted emergency response plan or emergency evacuation plan? 3.7.4.5 Construction Impacts Common Build Alternative Element Impacts None of the roadways within the Project area were identified as emergency response or evacuation routes on the California Office of Emergency Services website or in any of the general plans within the cities in the Project area or in the Orange County General Plan. Construction of the proposed Project would require temporary closure of traffic lanes to install new pipes, rehabilitate existing pipes, replace/rehabilitate manholes, and reconnect local sewers. Daily lane closures would involve a maximum reduction of up to 25 feet of roadway for a distance up to 1,000 feet for each project under construction.The proposed Project would not result in closure of major arterials.As discussed in Section 3.12 Traffic, prior to construction, the contractor would be required to submit traffic control plans for approval by each affected jurisdiction. A component of each traffic control plan would require the maintenance of local and emergency access at all times. Construction activities would be coordinated in advance with each jurisdiction and would not substantially impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan.The construction of the proposed Project would have a less than significant effect on emergency response and evacuation. Rehabilitation of Western Regional Sewers, Project 3-64 3-127 3.7-Hazards and Hazardous Materials 3.7.4.6 Operatfo tallmpacts Operations for both build alternatives would be similar to existing conditions as discussed above and consist of trips within the Project area to complete routine maintenance; clean sewer lines and manholes; perform visual inspection utilizing closed-circuit television and camera inspection; conduct flow-monitoring, as-needed repairs, and chemical dosing for odor and corrosion control; and operate the air scrubber if it is selected for the proposed Project. Many of these activities would also require temporary lane closures to accommodate sewer maintenance. Maintenance activities would be coordinated in advance with each jurisdiction.OCSD would complywith each corresponding jurisdiction's requirements for encroachment into the city streets (e.g., prepare traffic control plans, comply with Work Area Traffic Control Handbook,etc.),a component of which would require the maintenance of local and emergency access at all times prior to any encroachment into city streets. The operation of the proposed Project would have a less than significant impact on emergency response and evacuation. 3.7.4.7 No Build Alternative Under the No Build Alternative, there would be no rehabilitation or replacement of the Western Regional Sewers or improvements at the Westside Pump Station. The No Build Alternative would not result in hazardous emissions, create a significant hazard to the public or environment,or interfere with emergency plans. Operations of the Western Regional Sewers, as described in Section 2.6, would continue, including the use and handling of hazardous chemicals for corrosion and odor control. 3.7.5 Mitigation Measures HAZ MM 1: The contractor shall be responsible for providing trained personnel for monitoring and operation of construction activities and spill management, including cleanup and replacement of damaged property and fines. In the event an unauthorized spill occurs during construction activities, the contractor shall contact the appropriate agencies for cleanup and disposal pursuant to all applicable federal, state, and local laws and regulations. 3.7.6 Level of Significance after Miti ag tion With implementation of HAZ MM 1, contaminated soil and/or groundwater would be identified prior to construction. Information obtained during the subsurface soil and groundwater sampling program would ensure proper handling and disposal of contaminated soil and/or groundwater encountered within the proposed Project area. With implementation of HAZ MM 1, hazards to the public and the environment would be less than significant with mitigation.

Rehabilitation of Western Regional Sewers, Project 3-64 3-146 3.8-Land Use and Planning Other impact significance criteria for land use, identified in Appendix G of the CEQA Checklist,have been evaluated previously in Section 4.10 of the Initial Study for the proposed Project (See Appendix A).This previous evaluation determined that the proposed Project would result in either no impact or in less than significant impacts to land use under these criteria. As a result, the following impact significance criteria have not been evaluated further within this Environmental Impact Report(EIR): • Physically divide an established community? • Conflict with any applicable habitat conservation plan or natural community conservation plan? 3.8.4 Impact Analysis No differences between the two build alternatives are anticipated as they relate to impacts to land use. Thus,the impacts described in this section are the same for Build Alternative 1 and Build Alternative 2. LU-1: Conflict with any applicable land use plan, policy, or regulation of an agency with jurisdiction over the project (including, but not limited to the general plan, specific plan, local coastal program, or zoning ordinance) adopted for the purpose of avoiding or mitigating an environmental effect? 3.8.4.1 Construction Impacts Implementation of the proposed Project would entail nighttime (typically after 7:00 p.m. or 8:00 p.m. until 6:00 a.m. or 7:00 a.m., as defined by the applicable cities' noise ordinances as indicated in Table 3.8-2) construction in various locations in order to minimize disruptions to traffic. An example of such an occurrence would be construction activities at major intersections. Construction activities at such times may conflict with local plans, ordinances, or requirements pertaining to nighttime lighting and noise. Implementation of appropriate mitigation measures and coordination with pertinent jurisdictional authorities would reduce construction-related impacts during nighttime hours to less than significant levels(see Section 3.8.5).The applicable policies regarding construction lighting and glare and noise are summarized in Table 3.8-2. Table 3.8-2:land Use and Planning Consistency Analysis Section and Policy Analysis Consistency County of Orange Municipal Nighttime construction activities Consistent with Mitigation.

Aesthetics/Visual Resources AES MM 5: Should nighttime construction be required, OCSD will require that all lighting would be focused and directed onto the work area only.OCSD will monitor lighting to ensure that that there is no spillover outside the Project area. Air Quality AQ MM 1: OCSD shall require its construction contractor, either through the use of scheduling, sequencing of equipment usage, or other means, to demonstrate that construction- related activities for all Project segments will not generate daily emissions exceeding the SCAQMD NOxthreshold shown in Table 3.2-5. Noise NOI MM 1: OCSD will require the contractor to prepare a Noise Control Plan (NCP) demonstrating noise reduction, at minimum of 5 dBA to 10 dBA and below the 90-dBA Federal Transit Authority threshold, prior to commencing any construction. The NCP will specifically address noise control near sensitive receptors and for construction for which a variance has been obtained from the appropriate jurisdiction (e.g., weekend and nighttime construction).The NCP will identify the location of noise-sensitive receptors and list the types of noise control measures proposed (e.g., sound blankets and temporary noise barriers providing 5 dBA to 23 dBA of noise reduction) and any conditions specified in the variance. Once approved by OCSD,the contractor will be required to implement the plan. To ensure compliance with the NCP, the contractor will be required to monitor all construction noise for activities potentially affecting sensitive receptors in areas approved by variance, as well as all schools, hospitals, convalescent homes, churches, and other noise-sensitive areas within 1,000 feet of construction activities. If construction activities take Place during weekend and nighttime hours near sensitive receptors that have activities occurring on site during these times, coordination will be conducted with the site owners/managers to ensure adequate measures are taken to reduce or avoid noise impacts. NOI MM 2: The contractor will adhere to the specified hours in all local ordinances when construction activities are permitted. A variance will be required prior to construction if activities are planned to occur outside the permitted hours. OCSD will comply with any conditions specified in the variance. The following will minimize noise generated by all construction activities: Rehabilitation of Western Regional Sewers, Project 3-64 3-159 3.8-Land Use and Planning • All construction equipment shall be maintained according to manufacturer's specifications and inspected regularly. • All noise-producing construction equipment shall be equipped with muffling devices, quiet use generators, or other equivalent noise-reducing features to minimize temporary noise. • Stationary sources shall be located a minimum of 25 feet (the closest distance used to estimate construction noise impacts) from noise-sensitive receptors, unless otherwise constrained by site-specific conditions. • The use of noise-producing signals such as horns,whistles,alarms, bells,etc.shall be in accordance with federal,state,and local regulations. • Sound blankets and temporary noise barriers shall be located adjacent to construction activities where noise impacts above the regulated maximum levels are anticipated near noise-sensitive receptors. 3.8.6 Level of Significance after Mitigation With implementation of measures NOI MM 1, NOI MM 2,AQ MM 1, and AES MM 5, impacts on land use and planning from noise-sensitive receptors, unless otherwise constrained by site-specific conditions would be less than significant.

It discusses the existing noise environment as well as the regulatory framework for noise control. It also analyzes the proposed Project's effect on the existing ambient noise environment during construction and operation. Potential impacts would be temporary only during construction, and no long-term operational impacts are anticipated. 3.9.1 Regulatory Setting 3.9.1.1 Federal Federal Noise Control Act The United States (U.S.) Environmental Protection Agency (USEPA) Office of Noise Abatement and Control was originally established to coordinate federal noise control activities. After its inception, the USEPA Office of Noise Abatement and Control established the Federal Noise Control Act of 1972 (42 United States Code [U.S.C.] 4901 et seq.) to identify and address the effects of noise on public health, welfare, and the environment. In 1981, USEPA administrators determined that subjective issues such as noise would be better addressed at more local levels of government. Consequently, in 1982 responsibilities for regulating noise control policies were transferred to state and local governments; however, noise control guidelines and regulations contained in the USEPA rulings in prior years remain in place for enforcement by designated federal agencies where relevant. Federal Highway Administration Standards The standards in 23 Code of Federal Regulations, Part 772, set procedures for the abatement of highway traffic noise and construction noise. Title 23 is implemented by the Department of Transportation Federal Highway Administration (FHWA).The purpose of these regulations is to provide procedures for noise studies and noise abatement measures to help protect the public health and welfare, to supply noise abatement criteria, and to establish requirements for information to be given to local officials for use in the planning and design of highways. Federal Transit Administration Standards and Federal Railroad Administration Standards As described in the Federal Transit Administration's (FTA's) Transit Noise and Vibration Impact Assessment (FTA 2006), groundborne vibration can be a serious concern for nearby neighbors of a transit system route or construction site. Groundborne vibration can cause buildings to shake and rumbling sounds to be heard.The FTA assessment guidelines indicate that 90 A-weighted decibels(dBA; see Section 3.9.3.1 for a discussion of decibel weighting) during daytime hours(7:00 a.m.to 10:00 p.m.) and 80 dBA during nighttime hours (10:00 p.m. to 7:00 a.m.) are thresholds where adverse community reaction could occur for construction activities on a temporary basis. Rehabilitation of Western Regional Sewers, Project 3-64 3-169 3.9-Noise 3.9•1.2 State California Department of Health Services Section 65302(f) of the California Government Code establishes the requirement that local land use planning jurisdictions prepare a General Plan. The Noise Element is a mandatory component of the General Plan. It includes general community noise guidelines developed by the California Department of Health Services (DHS) and specific planning guidelines for noise/land use compatibility developed by the local jurisdiction. The California Department of Health Services has developed guidelines (1987) for Community Noise Equivalent Levels(CNELs), as discussed in Section 3.9.3 below,that are acceptable for use by local agencies. Selected relevant levels are as follows: • CNEL below 60 dBA: normally acceptable for low-density residential use • CNEL of 55 to 70 dBA:conditionally acceptable for low-density residential use • CNEL below 65 dBA: normally acceptable for high-density residential use • CNEL of 60 to 70 dBA: conditionally acceptable for high-density residential, transient lodging, churches,educational and medical facilities • CNEL below 70 dBA: normally acceptable for commercial uses • CNEL below 77 dBA:conditionally acceptable for commercial uses • CNEL below 75 dBA: normally acceptable for industrial uses • CNEL below 80 dBA:conditionally acceptable for industrial uses "Normally acceptable" is defined as satisfactory for the specified land use, assuming that normal conventional construction is used in buildings. "Conditionally acceptable" may require some additional noise attenuation or special study. "Normally unacceptable" levels begin where the conditionally acceptable ranges end. The "normally acceptable" thresholds listed above were used to establish significance thresholds for operational noise. California Noise Control Act of 1973 Sections 46000-46080 of the California Health and Safety Code, known as the California Noise Control Act of 1973, find that excessive noise is a serious hazard to the public health and welfare and that exposure to certain levels of noise can result in physiological, psychological, and economic damage. It also finds that a continuous and increasing level of noise is a presence in California's urban, suburban, and rural areas. The California Noise Control Act declares that the state has a responsibility to protect the health and welfare of its citizens by the control, prevention, and abatement of noise. It is the policy of the state to provide an environment for all Californians free from noise that jeopardizes their health or welfare. Rehabilitation of Western Regional Sewers, Project 3-64 3-170 3.9-Noise California Department of Transportation Because the local municipalities do not have regulatory standards for vibration sources, potential structural damage and human annoyance associated with vibration from construction activities were evaluated based on California Department of Transportation (Caltrans)vibration limits(see Table 3.9-1). A vibration level of 0.20 peak particle velocity inches per second (ppv/ips)was used to evaluate impacts on nearby receptors, since this level represents the threshold at which temporary vibrations typically become annoying and at which there is a risk of architectural damage, such as plaster cracking, in normal dwellings(Caltrans 2004).

The applicable local noise and vibration regulations are summarized in Table 3.9-2. None of the local ordinances has established a noise level threshold for construction activities.All local ordinances exempt noise and vibration from construction activities either at all times or within specified hours of the day and/or night.

For single-family and multiple-family areas, a 55 to 65 dBA CNEL is "normally acceptable." Other land uses such as commercial, industrial, and recreational areas have a CNEL up to 70 dBA as "normally acceptable." Construction noise standards are established by the City Municipal Code as listed above. City of Buena Park For single-family and multiple-family areas, the City of Buena Park General Plan Noise Element has established 50 to 60 dBA CNEL and 50 to 65 dBA CNEL, respectively, as "normally acceptable." Other land uses such as schools, places of worship, commercial, and recreational areas have a CNEL up to 70 dBA as "normally acceptable" Industrial areas have a CNEL up to 75 dBA as "normally acceptable" Construction noise standards are established by the City Municipal Code as listed above. City of Anaheim The City of Anaheim General Plan recognizes that construction is a necessity, and noise control for construction needs to be carefully balanced. Measures to reduce construction noise should be implemented when necessary. "Normally acceptable" noise levels by land use type follow the California DHS criteria listed above. Construction noise standards are established by the City Municipal Code listed above. City of cypress The City of Cypress General Plan Noise Element Land Use Compatibility Index lists 50 to 60 dBA CNEL as "normally acceptable" for single-family and multiple-family uses, schools, and places of worship; up to 65 dBA CNEL for hotels and commercial uses; and up to 70 dBA CNEL for recreational areas and Industrial uses.Construction noise standards are established by the City Municipal Code listed above. City of Los Alamitos The City of Los Alamitos General Plan considers excessive noise to adversely affect human health and well-being, economic productivity, and property values. Mobile and stationary noise sources contribute to overall noise levels,and the impacts of both must be analyzed when planning the City's future growth and management.The General Plan Land Use and Noise Compatibility Matrix lists 60 to 65 dBA CNEL as "normally acceptable" for single-family and multiple-family uses, hotels, schools, and places of worship and 70 dBA CNEL or more for commercial and industrial uses. The City Municipal Code sets thresholds for stationary sources.Standards for construction noise from the Code are listed above. Rehabilitation of Western Regional sewers, Project 3-64 3-173 3.9-Noise City of Seal Beach The City of Beach General Plan Noise Element establishes "normally acceptable" noise levels by land use type following the California DHS criteria listed above. Construction noise standards are established by the City Municipal Code listed above. Unincorporated Orange County The Orange County General Plan Noise Element establishes compatibility standards for different land use types. For example, in residential areas the CNEL standard is 65 dBA or below. Construction noise standards are established by the Noise Ordinance listed above. 3.9•1.4 Methodology The Federal Highway Administration (FHWA) Roadway Construction Noise Model (RCNM) is used to assess potential short-term construction impacts. In estimating noise exposures for construction equipment, it was assumed that attenuation would be by geometric spreading and ground surface absorption. Sound from a stationary or point noise source (i.e., manholes, pump stations) diminishes with distance.The sound level attenuates(or decreases) at a rate of 6 dBA for each doubling of distance from a point source. Sound from a mobile or line noise source(i.e.,sewer pipelines) could affect a larger area and potentially more receptors due to movement representing the effect of several point sources. Sound levels attenuate at a rate of 3 dB for each doubling of distance from a line source. Construction methods would include open-trench excavation, sewer lining and manhole rehabilitation (i.e., cured-in-place pipe installation), and pump station rehabilitation. Construction equipment used for the proposed Project would include:excavators,front-end loaders, cranes, dump trucks, delivery trucks, concrete trucks, pickup trucks, backhoes, pavement saws, diesel generators, air compressors, asphalt trucks, paving machines, rollers, contractor support trucks, and bypass pumps. For an example of the type of equipment used to reconstruct the Westside Pump Station, refer to Table 2.4-1, Estimated Construction Work Effort and Associated Equipment. Cured-in-place pipe (CIPP) installation would include a felt truck or boiler truck. The loudest piece of equipment operating during CIPP installation would be the air compressors. The generators on the trucks would be contained in an enclosure to reduce noise levels. Section 2.5 provides a detailed description of construction methods. Construction of the proposed sewer pipelines is considered a linear activity and would continuously move during the Project construction phases. Therefore, excavation, installation, and paving activities were analyzed concurrently for open-trench excavation, which is essentially the worst-case condition. Rehabilitation of the manholes and pipelines using CIPP installation would be considered a stationary activity, since construction equipment would remain in one place. Construction of the pump station would be considered a stationary activity and could occur at any time. The majority of the residential development within the proposed Project area is shielded by existing privacy walls ranging in height from 6 to 8 feet tall. Since the actual noise reduction from the existing Rehabilitation of Western Regional Sewers, Project 3-64 3-174 3.9-Noise walls is unknown, existing mitigation was not included in the model calculations in order to analyze a worst-case scenario. 3.9.2 Existing Conditions The existing conditions section explains the fundamentals of noise and groundborne vibration and describes existing noise sources and the location of noise-sensitive receptors in the proposed Project area and the ambient noise conditions throughout the Project area. 3.9.2.1 F7cndameata/s of Noise and Groundborne Vibration Sound is created when an object vibrates and radiates part of its energy as acoustic pressure or waves through a medium, such as air, water, or a solid object. Sound levels are expressed in units called decibels (de). The logarithmic scale compresses the wide range in sound levels resulting in a more usable range of sound level values, similar to the Richter scale used to measure earthquakes. Noise is generally defined as any loud or undesired sound and is also expressed in dB. The ability of an average individual to perceive a change in noise levels is well documented. Generally, changes in noise levels of 3 dB would be barely perceived by most listeners, whereas a 10-dB change normally is perceived as a doubling of noise for the listener. This is consistent with FHWA noise policy guidance and with the approach utilized within the Caltrans Technical Noise Supplement(Caltrans 2013a).The general principal that most noise acceptability criteria are based upon is that a perceptible change in noise is likely to cause annoyance wherever it intrudes upon existing noise from all other sources. Annoyance depends upon the noise that exists before the introduction of a new sound. The human ear is not equally sensitive to all frequencies in the entire spectrum,so noise measurements are weighted more heavily for frequencies to which humans are sensitive in a process called "A- weighting," or"dBA."The A-weighted sound level is widely accepted by acousticians as a proper unit for describing environmental noise. Typical daily sounds in the environmental range from 30 dBA (a very quiet rural or interior environment) to 85 dBA (occurring on a sidewalk adjacent to heavy traffic). Table 3.9-3 describes typical A-weighted noise levels for various noise sources. Table 3.9-3:Typical A-Weighted Noise Levels OutdoorCommon 110 Indoor band Jet fly-over at 1000 feet 100 Gas lawn mower at 3 feet 90 Diesel truck at 50 feet at 50 mph Food blender at 3 feet 80 Garbage disposal at 3 feet Noisy urban area,daytime Gas lawn mower,100 feet 70 Vacuum cleaner at 10 feet Commercial area Normal speech at 3 feet Rehabilitation of Western Regional sewers, Project 3-64 3-175 3.9-Noise Table 3.9-3:Typical A-Weighted Noise Levels Common Outdoor Activities Noise Level (dBA) Common Indoor Activitles Heavy traffic at 300 feet 60 Large business office Quiet urban daytime 50 Dishwasher next room Quiet urban nighttime 40 Theater,large conference room (background) Quiet suburban nighttime 30 Library Quiet rural nighttime 20 Bedroom at night 10 Broadcast/recording studio Lowest threshold of human hearing 0 Lowest threshold of human hearing Source:Caltrans 2013b To characterize the noise environment in a given area, the following noise descriptors are commonly used. • Maximum Sound Level (L..). The maximum sound level measured during the measurement period • Minimum Sound Level (L,;,,). The minimum sound level measured during the measurement period • Equivalent Sound Level (LQ•). The equivalent steady state sound level that in a stated period of time would contain the same acoustical energy • Day/night Average Noise Level (Ld„ or CNEL). Both descriptors provide the same 24-hour level with 30 dBA applied to the actual noise level during the hours from 10:00 p.m.to 7:00 a.m.The CNEL also requires that 5 dBA be applied to the actual noise level during the hours from 7:00 p.m. to 10:00 p.m. The applied increments take into account a person's increased sensitivity to noise during these periods. Sound Propagation When sound propagates over a distance, it changes in level and frequency content.The manner in which noise reduces with distance depends on the following factors. Rehabilitation of Western Regionol Sewers, Project 3-64 3-176 3.9-Noise Geometric Spreading Sound from a stationary or point noise source (i.e., manholes, pump stations) diminishes with distance. The sound level attenuates (or decreases) at a rate of 6 dB for each doubling of distance from a point source. Sound from a mobile or line noise source (i.e., sewer pipelines) could affect a larger area and potentially more receptors due to movement representing the effect of several point sources. Sound levels attenuate at a rate of 3 dB for each doubling of distance from a line source. Ground Absorption The propagation path of noise from a roadway to receptor is usually very close to the ground. Noise attenuation from ground absorption and reflective-wave canceling adds to the attenuation associated with geometric spreading. Traditionally, the excess attenuation has also been expressed in terms of attenuation per doubling of distance.This approximation is usually sufficiently accurate for distances of less than 200 feet. For acoustically hard sites(i.e.,sites with a reflective surface between the source and the receptor, such as a parking lot or body of water), no excess ground attenuation is assumed. For acoustically absorptive or soft sites (i.e., those sites with an absorptive ground surface between the source and the receptor, such as soft dirt, grass, or scattered bushes and trees), an excess ground- attenuation value of 1.5 dB per doubling of distance is normally assumed. Shieldine by Natural or Human-Made Features A large object or barrier in the path between a noise source and a receptor can substantially attenuate noise levels at the receptor.The amount of attenuation provided by shielding depends on the size of the object and the frequency content of the noise source. Natural terrain features (e.g., hills and dense woods) and human-made features (e.g., buildings and walls)can substantially reduce noise levels.Walls are often constructed between a source and a receptor specifically to reduce noise.A barrier that breaks the line of sight between a source and a receptor would typically result in at least 5 dB of noise reduction. Taller barriers provide increased noise reduction. Vegetation between the noise source and receptor is rarely effective in reducing noise because it does not create a solid barrier. Groundborne Vibration In contrast to airborne noise, groundborne vibration (GBV) is not a phenomenon experienced by most people on a daily basis. Typical outdoor sources of perceptible GBV are construction equipment and traffic on rough roads. Figure 3.9-1 depicts the typical levels of GBV. The effects of GBV include perceptible (without the use of instruments) movement of the building floors, rattling of windows, shaking of items on shelves or hanging on walls, and rumbling sounds. Groundborne noise (GBN) is the rumbling sound caused by the vibration of room surfaces. The annoyance potential of GBN is usually characterized with the A-weighted sound level. GBV is almost never annoying to people who are outdoors. The ground motion caused by vibration is measured as particle velocity in inches per second and is referenced as vibration decibels(VdB).

Noise-sensitive receptors can best be defined as those locations or areas where dwelling units or other fixed, developed sites of frequent human use occur. Noise-sensitive receptors identified for the proposed Project include residences, lodging (hotels, motels, and similar uses), places of worship, Rehabilitation of Western Regionol Sewers, Project 3-64 3-178 3.9-Noise cemeteries, restaurants, educational facilities (schools), childcare facilities, recreational (golf courses, parks), hospitals, and libraries (see Figure 3.9-2 through Figure 3.9-13).The majority of the Project area is urban with dense residential development adjacent to the proposed Project corridors. Ambient Noise Levels Ambient noise levels within the Project area vary depending on the location, degree of development, and general human activity in the area. Due to the numerous noise-sensitive sites in the Project area, noise levels were determined based on a combination of field-measured levels at representative locations along each proposed pipeline alignment and estimated noise exposure levels as defined in the Federal Transit Administration Transit Noise and Vibration Impact Assessment manual (FTA 2006). The field-measured ambient noise levels were compared to the FTA estimates to ensure the estimates were representative of existing conditions(see Figure 3.9-2 through Figure 3.9-13). In November 2015, noise measurements were collected at 13 locations within the Project area using a Quest 2900 sound level meter categorized as a Type I (precision grade) device. The sound level meter was placed 5 feet above ground surface to represent the average height of a human ear. Noise measurements were collected during typical weekday hours (between 8:00 a.m. and 5:00 p.m.) for a duration of 30 minutes at each location. Table 3.9-4 summarizes the field noise measurement data. At some measurement locations, the recorded levels were compromised by individual events such as local construction, emergency vehicle sirens, or other atypical noise sources that temporarily raised the ambient noise environment above what would typically be expected. The table also presents ambient noise levels based on estimates of existing noise exposure as function of population density, defined in the FTA Transit Noise and Vibration Impact Assessment manual (FTA 2006).

Project noise impacts would be significant if the proposed Project would result in: Rehabilitation of Western Regionol Sewers, Project 3-64 3-181 3.9-Noise NOI-1: Exposure of persons to or generation of noise levels in excess of standards established in the local general plan or noise ordinance or applicable standards of other agencies NOI-2: Exposure of persons to or generation of excessive groundborne vibration or groundborne noise levels NOI-3: A substantial permanent increase in ambient noise levels in the project vicinity above levels existing without the project NOI-4: A substantial temporary or periodic increase in ambient noise levels in the project vicinity above the ambient noise conditions Other impact significance criteria for Noise, identified in Appendix G of the CEQA Checklist, have been evaluated previously in Section 4.12 of the Initial Study for the proposed Project (See Appendix A). This previous evaluation determined that the proposed Project would result in either no impact or in less than significant impacts to noise resources under these criteria. As a result, the following impact significance criteria have not been evaluated further within this Environmental Impact Report(EIR): • For a project located within an airport land use plan or, where such a plan has not been adopted, within 2 miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels? • For a project within the vicinity of a private airstrip,would the project expose people residing or working in the project area to excessive noise levels? 3.9.4 Impact Analysis This section discusses the proposed Project's short-term (construction-related) and long-term (operations) potential noise and vibration impacts. Construction of the proposed Project would generate noise from the use of construction equipment as well as vehicle trips by construction workers and supply trucks traveling to and from the Project area and could result in temporary noise impacts. The areas where most noise and vibration would be generated would be associated with the replacement activities along portions of the Los Alamitos Sub- trunk and the Westside Relief Interceptor pipelines, as well as the Westside Pump Station where numerous noise-sensitive receptors are located (see Figure 3.9-1). The proposed Project would construct sewer pipelines in a linear fashion for open-cut trenching and CIPP installation, and approximately 50 to 150 feet of pipeline would be completed per day depending on site conditions.The proposed Project would require excavation for installation of new 21-to 39-inch pipes at depths of up to 22.7 feet below ground surface (bgs) and 31.3 feet bgs for Build Alternative 1 and Build Alternative 2, respectively. Trenches to accommodate the new pipe would be up to 7 feet wide. The construction area associated with replacement would be up to 1,000 feet long and 25 feet wide. Rehabilitation of Western Regional Sewers, Project 3-64 3-182 3.9-Noise As discussed in Section 2.5.6 Construction Schedule and Cost,the construction schedule allows sufficient time (4 years or 1,460 days)to construct each Project segment sequentially for either build alternative; however, construction activities for the proposed Project are anticipated to last for approximately 24 to 30 months within this time frame. Section 2.5 provides a detailed description of construction methods. Appendix E summarizes the construction method, construction equipment type, quantity of equipment, hours of operation, number of working days,and number of workers on site for each activity. Construction equipment and materials would be held in staging areas in parking lots, vacant lots, or segments of street lanes that are temporarily closed to minimize hauling trips and long-term disruption. NOI-1: Exposure of persons to or generation of noise levels in excess of standards established in the local general plan or noise ordinance or applicable standards of other agencies? 3.9.4•1 COnstructionlmpacts Noise levels would vary depending on the type of equipment used, how and when it operates, and how well it is maintained. Appendix E provides detailed estimates of construction noise levels by activity. Table E1 in Appendix E summarizes the results of the construction noise analysis presented in detail in Appendix E. Noise level thresholds have not been established in any of the local noise ordinances listed in Table 3.9-4 or related general plan documents; and there are no federal or state regulations for construction noise. As set forth above, construction noise is exempt from each of the local noise ordinances listed in Table 3.9-4. Construction is assumed to occur within the hours specified in those local ordinances when construction activities are exempt.Therefore, construction of the proposed Project would not generate noise levels in excess of established standards. Implementation of the proposed Project would entail nighttime (typically after 7:00 p.m. or 8:00 p.m. until 6:00 a.m.or 7:00 a.m.,as defined by the applicable cities' noise ordinances)construction in various locations in order to minimize disruptions to traffic. An example of such an occurrence would be construction activities at major intersections. Construction activities at such times may conflict with local plans, ordinances, or requirements pertaining to nighttime lighting and noise. This would constitute a significant impact. Implementation of appropriate ECMs and mitigation measures NOI MM 1 through NOI MM 3, as well as coordination with pertinent jurisdictional authorities, would reduce construction-related impacts to less than significant levels. Common Build Alternative Element Impacts Noise levels generated during construction of the Seal Beach Blvd. Interceptor and the Orange-Western Sub-trunk, which would include the CIPP rehabilitation and manhole replacement/rehabilitation activities,would be identical (89 dBA at a distance of 25 feet) under both build alternatives.These noise levels would exceed FTA thresholds where adverse community reaction could occur for construction activities on a temporary basis during nighttime hours (10:00 p.m. to 7:00 a.m.). Similarly, noise levels Rehabilitation of Western Regional Sewers, Project 3-64 3-183 3.9-Noise generated from construction activities for the Westside Pump Station would be identical (100 dBA at a distance of 15 feet) under both build alternatives. These noise levels would exceed FTA thresholds where adverse community reaction could occur for construction activities on a temporary basis during daytime hours (7:00 a.m.to 10:00 p.m.). Noise-sensitive receptors include residents, schools, places of worship, and recreational areas; and the nearest receptors are located within 15 feet, 25 feet, and 50 feet from the proposed improvements for the Westside Pump Station, the Orange Western Sub-trunk, and the Seal Beach Blvd. Interceptor, respectively. Construction would generate noise within the Project area that would be temporary and of short duration (representing a maximum level). However, FTA thresholds, where adverse community reaction could occur for construction activities on a temporary basis, would be exceeded; and impacts would be significant. Implementation of appropriate ECMs and mitigation measures NOI MM 1 and NOI MM 2, as well as coordination with pertinent jurisdictional authorities,would reduce construction-related impacts to less than significant levels. Build Alternative 1 Construction activities for the Los Alamitos Sub-trunk replacement areas from approximately La Palma Avenue to West Cerritos Avenue would generate noise levels of 92 dBA at a distance of 25 feet. However, from West Cerritos Avenue to Seal Beach Boulevard, where rehabilitation is anticipated, construction activities would generate noise levels of 89 dBA at a distance of 25 feet. Noise-sensitive receptors include residents, schools, and recreational areas; and the nearest receptor is located approximately 15 feet from the proposed improvements. These noise levels would exceed FTA thresholds where adverse community reaction could occur for construction activities on a temporary basis. Construction activities for the Westside Relief Interceptor replacement areas from approximately Ball Road to Bradbury Road would generate noise levels of 92 dBA at a distance of 25 feet. However, from Crescent Avenue to Ball Road and Bradbury Road to Seal Beach Boulevard, where rehabilitation is anticipated, construction activities would generate noise levels of 89 dBA at a distance of 25 feet. Noise- sensitive receptors include residents,schools, and places of worship; and the nearest receptor is located approximately 15 feet from the proposed improvements. These noise levels would exceed FTA thresholds where adverse community reaction could occur for construction activities on a temporary basis. Compared to Build Alternative 2,overall noise impacts would be less forthe Los Alamitos Sub-trunk,due to portions of this pipeline that would only be rehabilitated, and greater with the Westside Relief Interceptor,due to portions ofthe pipeline being replaced. Rehabilitation of Western Regional sewers, Project 3-64 3-184 3.9-Noise Construction would generate noise within the Project area that would be temporary and of short duration (representing a maximum level). Adherence to the Project noise-related ECMs identified in Table 2.10-1 would help reduce these noise levels. However, FTA thresholds,where adverse community reaction could occur for construction activities on a temporary basis, would be exceeded and impacts would be significant. Implementation of mitigation measures NOI MM 1 and NOI MM 2, as well as coordination with pertinent jurisdictional authorities, would reduce construction-related impacts to less than significant levels. Build Alternative 2 As shown in Table El (Appendix E), noise-sensitive receptors including schools, recreational uses, and residences that are located near construction activities for the Los Alamitos Sub-trunk replacement would be exposed to 92 dBA at a distance of 25 feet. Noise-sensitive receptors that are located near construction activities for the Westside Relief Interceptor rehabilitation would be exposed to 89 dBA at a distance of 25 feet. Compared to Build Alternative 1, overall noise impacts for the entire pipeline would be greater for the Los Alamitos Sub-trunk, since the entire pipeline would be replaced, and less with the Westside Relief Interceptor, since the pipeline would only be rehabilitated. These noise levels would exceed FTA thresholds where adverse community reaction could occur for construction activities on a temporary basis. Construction would generate noise within the Project area that would be temporary and of short duration (representing a maximum level). Adherence to the Project noise-related ECMs identified in Table 2.10-1 would help reduce these noise levels. However, FTA thresholds,where adverse community reaction could occur for construction activities on a temporary basis, would be exceeded; and impacts would be significant. Implementation of mitigation measures NOI MM 1 and NOI MM 2, as well as coordination with pertinent jurisdictional authorities, would reduce construction-related impacts to less than significant levels. 3.9.4.2 Operation llmpacts Operational noise associated with both of the build alternatives would be similar to existing conditions and associated with vehicle trips to complete routine maintenance; clean sewer lines and manholes; perform visual inspection utilizing closed-circuit television and camera inspection; conduct flow monitoring, as-needed repairs, and chemical dosing for odor and corrosion control; and operate the air scrubber, if included in the proposed Project. During operation, the air scrubber would produce a maximum of 85 dBA at a reference distance of 25 feet. Should it be determined that the air scrubber unit would be necessary, Orange County Sanitation District (OCSD) would construct a new enclosure to house the air scrubber unit.Typical noise attenuation across a masonry building exterior ranges from 10 dBA(with open windows)to 35 dBA(with closed double-glazed windows). OCSD's new enclosure would be designed to common construction standards and attenuate operational noise to achieve the maximum noise reduction and obtain an exterior noise level of 50 dBA adjacent to the building,which is below 60 dBA and would be considered "normally acceptable' for outdoor residential exposure. Since Rehabilitation of Western Regional sewers, Project 3-64 3-185 3.9-Noise existing and future operations are similar and noise from the proposed air scrubber would be reduced to "normally acceptable" levels, completion of the proposed Project would result in no significant change of operational noise from the baseline conditions. Therefore, operational noise would be less than significant. N0I-2; Exposure of persons to or generation of excessive groundborne vibration or groundborne noise levels? 3.9.4.3 Constmctionimpacts Groundborne vibration and groundborne noise levels are generally caused by impact devices such as pile driving. Use of these devices would not be utilized during construction of the pipelines; however, operation of heavy equipment may generate localized groundborne vibration and noise that could be perceptible to sensitive receptors within close proximity. Annoyance Assessment No vibration thresholds for annoyance are specified in the local ordinances. Therefore, vibration levels were estimated and compared to Caltrans annoyance criteria listed in Table 3.9-1. Vibration levels from construction equipment used for excavation and pipe replacement were estimated to range from 0.003 to 0.089 inch per second (IPS) at a distance of 25 feet along segments of the Los Alamitos Sub-trunk and Westside Relief Interceptor, based on average levels for similar construction equipment reported in the FTA general assessment guidance (FTA 2006). This is below the 0.2 IPS Caltrans guideline indicating when vibrations are perceived as an annoyance by building inhabitants. In the vicinity of where the proposed Project pipe rehabilitation would occur, people in the closest residences, schools, and daycare facilities are not anticipated to perceive vibration during these construction activities as annoyances, including OC Kids Childcare, located adjacent to Denni Street and approximately 25 to 30 feet from the proposed Westside Relief Interceptor rehabilitation improvements. This is because the anticipated vibration would be below the cited Caltrans annoyance criteria(0.2 IPS). The pump station is located in a residential subdivision adjacent to residences (within approximately 15 feet). As such, should the project require pile driving equipment for shoring installation (see Appendix E), a non-vibratory type of equipment would be used.Since non-vibratory equipment would be used and with implementation of mitigation measures NOI MM 1 and NOI MM 2, as described in Section 3.9.5 below, people in the adjacent residences are not anticipated to experience annoyance from vibration generated from construction. Vibration impacts would be less than significant with implementation of mitigation measures NOI MM 1 and NOI MM 2. Damage Assessment Construction vibration damage criteria (inches per second or IPS), as defined by Caltrans,were used for the damage assessment of vibration during project construction and range from a 0.2 IPS threshold, at Rehabilitation of Western Regional Sewers, Project 3-64 3-186 3.9-Noise which there is a risk of"architectural" damage to normal dwellings with plastered walls and ceilings, to 0.6 IPS,where "architectural"and possibly minor structural damage would occur. According to FTA guidelines, vibration levels from construction equipment used for excavation and pipe replacement would range from 0.003 to 0.089 IPS at 25 feet along segments of the Los Alamitos Sub- Trunk and Westside Relief Interceptor; therefore, vibration damage associated with replacement and rehabilitation activities for both of the build alternatives to the buildings closest to these proposed activities is not anticipated. The pump station is located in a residential subdivision adjacent to residences (within approximately 15 feet). As such, should the project require pile driving equipment for shoring installation (see Appendix E), a non-vibratory type of equipment would be used.Since non-vibratory equipment would be used and with implementation of mitigation measures NOI MM 1 through MOI MM 3, as described in Section 3.9.5 below, vibration impacts relative to damage assessment would be reduced to a less than significant level. 3.9.4.4 Operationallmpacts Following construction, only the potential operation of the air scrubber at Westside Pump Station could result in groundborne noise or vibration. During operation, the air scrubber would be anticipated to operate at or below the 0.08-IPS level of perceptibility at a reference distance of 25 feet. The air scrubber would be constructed within a new enclosure adjacent to the existing building, which would attenuate the vibration of this equipment during operation, as discussed above.Therefore,operation of the proposed Project would not expose persons to or generate excessive groundborne vibration or groundborne noise levels. NOI-3; A substantial permanent increase in ambient noise levels in the project vicinity above levels existing without the project? 3.9.4.5 Construction Impacts Construction activities would be short-term at specific sites along the proposed Project alignment and temporary overall in that construction would be completed within approximately 24 to 30 months, as discussed previously. Construction activities would not result in permanent increases in ambient noise levels,and construction noise impacts would be less than significant. 3.9.4.6 Operation allmpacts All noise-sensitive receptors identified near the proposed Project area are located in Orange County.The County ordinance has established 20 dB over exterior noise level standards as the threshold for noise level increases. As defined in the County ordinance, the exterior noise level standard for residential areas during daytime hours (7:00 a.m. to 10:00 p.m.) is 55 dBA and during nighttime hours (10:00 p.m. to 7:00 a.m.) is 50 dBA, resulting in a maximum threshold of 75 dBA and 70 dBA for noise level increases Rehabilitation of Western Regional Sewers, Project 3-64 3-187 3.9-Noise during daytime and nighttime hours, respectively. All cities within the Project area and within Orange County are consistent with the County ordinance. Following construction,only the operation of the air scrubber at the Westside Pump Station could result in a permanent increase in ambient noise levels. During operation, the air scrubber would produce a maximum 85 dBA at a reference distance of 25 feet.The air scrubber would be constructed within a new enclosure adjacent to the existing building.Typical noise attenuation across a masonry building exterior ranges from 10 dBA(with open windows) to 35 dBA (with closed double-glazed windows). OCSD's new enclosure would be designed to common construction standards and attenuate operational noise to achieve the maximum reduction level and obtain a 50-dBA exterior noise level adjacent to the building. Adding the operational noise (after accounting for noise attenuation) to ambient conditions (ranging from 48 dBA to 78 dBA) would not result in noise level increases of 20 dB over ambient conditions or exceed the maximum threshold of 75 dBA as defined by the County ordinance.Therefore, operation of the proposed Project would not result in a substantial permanent increase in ambient noise levels. Operational noise would be less than significant. N014: A substantial temporary or periodic increase in ambient noise levels in the project vicinity above the ambient noise conditions? 3.9.4.7 COnstructiOn Impacts Although construction activities associated with the proposed Project would generate increases in noise levels, these increases would be temporary and of short duration. The local noise ordinances listed in Table 3.9-4 and related general plan documents have not established thresholds for noise level increases above ambient conditions during construction. In addition, there are no federal or state regulations that define a substantial noise increase threshold for construction. Therefore, the FTA 90-dBA guideline was used as an average threshold where adverse community reaction could occur on a temporary basis during daytime construction hours (7:00 a.m. to 7:00 p.m.). Construction noise levels were estimated per activity at 25 feet and for each doubling of distance. Noise-sensitive receptors that would experience construction noise levels at approximately 90 dBA or more are located 25 feet or less from the proposed improvements. Appendix E includes Table El detailing estimated construction noise levels per activity. Table E2 summarizes the results of the construction noise analysis. Figure 3.9-2 through Figure 3.9-13 depict the 90-dBA noise contour within the Project area. Common Build Alternative Element Impacts Existing noise levels range approximately from 63 dBA to 77 dBA in the area of the Orange-Western Sub- trunk and are estimated to be 65 dBA in the area of the Seal Beach Blvd. Interceptor. Near the Westside Pump Station, existing noise levels are estimated to be 65 dBA.Adding noise levels from construction of the proposed Project to ambient conditions would generate temporary increases in ambient noise levels at or above 90 dBA, mostly in the pipe replacement areas where open-trench construction would occur along portions of the Los Alamitos Sub-trunk. Because the ultimate pipe location and construction method would not be determined until final design, Figure 3.9-2 through Figure 3.9-13 depict the worst- Rehabilitation of Western Regional Sewers, Project 3-64 3-188 3.9-Noise case 90-dBA noise contour.This contour is based on open-cut construction with the sources generating construction noise being located within street rights-of-way. Therefore, the majority of the 90-dBA contour would likely fall within the roadway right-of-way, resulting in less than significant impacts to noise-sensitive receptors. Noise-sensitive receptors most impacted by construction noise include numerous residential developments along the proposed Project corridors where replacement activities would occur. Several schools at the following locations within close proximity to the proposed Project would also experience temporary noise increases during construction: • Rosecrans Elementary — The nearest outdoor use is located approximately 30 feet north from Orange Avenue and the Los Alamitos Sub-trunk proposed improvements. Estimated maximum construction noise levels at this location would be approximately 90 dBA during the excavation phase.Therefore, mitigation measures NOI MM 1 and NOI MM 3, as described in Section 3.9.5 below, are required; and noise impacts to the school would be less than significant with mitigation. • Educational Partnership High — The nearest building is located north of Bloomfield Street and approximately 60 feet west from the Los Alamitos Sub-trunk replacement improvements. Estimated maximum construction noise levels at this location would be approximately 89 dBA during the excavation phase. The nearest outdoor use is located further west and would be shielded by the school buildings. In addition, interior noise levels are anticipated to be substantially lower. Typical noise attenuation across a masonry building exterior ranges from 10 dBA (with open windows) to 35 dBA (with closed double-glazed windows). Therefore, noise impacts to the school would be less than significant. • Valencia Elementary —The nearest building is located approximately 100 feet west from Denni Street and the Los Alamitos Sub-trunk replacement improvements. Estimated maximum construction noise levels at this location would be approximately 87 dBA during the excavation phase. The nearest outdoor use is located further west and would be shielded by the school buildings. In addition, interior noise levels are anticipated to be substantially lower.Typical noise attenuation across a masonry building exterior ranges from 30 dBA (with open windows) to 35 dBA (with closed double-glazed windows). Therefore, noise impacts to the school would be less than significant. • Center for Early Education —The nearest building is located approximately 200 feet west from Denni Street and the proposed Los Alamitos Sub-trunk replacement improvements. Estimated maximum construction noise levels at this location would be approximately 84 dBA during the excavation phase. Interior noise levels are anticipated to be substantially lower. Typical noise attenuation across a masonry building exterior ranges from 10 dBA (with open windows) to 35 dBA (with closed double-glazed windows). Noise impacts to the school would be less than significant. Rehabilitation of Western Regional Sewers, Project 3-64 3-189 3.9-Noise Construction noise levels are not anticipated to exceed 90 dBA in pipe rehabilitation areas where CIPP installation would occur; however, in all areas, substantial increases over ambient noise levels up to approximately 20 dBA or more would still occur.As mentioned in the discussion of noise fundamentals, a change of 5 dB is clearly noticeable, and a change of 10 dB is perceived as doubling or halving sound level. Construction noise would be more noticeable in areas with low ambient noise levels such as those in the range of 40 to 50 decibels recorded at measurement locations M2 and M3 along Denni Street, M4 along Denni Street and Moody Street, and M10 along Los Alamitos Boulevard (Table 3.9-4). Temporary noise impacts would be significant and unavoidable even with implementation of mitigation measures NOI MM 1 and NOI MM 3. Existing privacy/noise walls ranging in heights from approximately 6 to 10 feet were observed adjacent to most of the residential developments identified within the proposed Project area. Therefore, estimated construction noise levels are anticipated to be lower due to shielding from the existing walls and at residences beyond the first row of homes due to shielding from existing structures. Noise walls can generally provide at least 5 dBA noise reduction if the wall breaks the line of sight from the noise source to the receptor. Although noise levels are anticipated to be lower with existing shielding (e.g., sound blankets on equipment could achieve a noise reduction level of as much as 23 dBA), as identified in ECM Table 2.10-1, as well as with implementation of mitigation measures NOI MM 1 and N01 MM 3, substantial noise increases are anticipated in the pipe rehabilitation areas based on the FTA daytime guideline (FTA 2006).Therefore,temporary noise impacts would be significant and unavoidable. If nighttime construction is required, exceedance of the FTA 80-dBA nighttime guideline could occur throughout the proposed Project area along all five of the proposed segments. Therefore, construction noise impacts would be significant; and mitigation measures NOI MM 1 and NOI MM 3, as described in Section 3.9.5 below, would be required. After mitigation, noise levels during construction would be reduced from 5 dBA to 23 dBA; however, even with these measures, temporary significant noise increases are still anticipated.Therefore,temporary noise impacts would be significant and unavoidable. Build Alternative 1 Existing noise levels in the areas of the Los Alamitos Sub-trunk and the Westside Relief Interceptor range from approximately 48 dBA to 76 dBA and 58 dBA to 76 dBA, respectively. Adding noise levels from construction of the proposed Project to ambient conditions would generate temporary increases in ambient noise levels at or above 90 dBA, mostly in the pipe replacement areas where open-trench construction would occur along portions of the Los Alamitos Sub-trunk and the Westside Relief Interceptor. Because the ultimate pipe location and construction method would not be determined until final design, Figure 3.9-2 through Figure 3.9-13 depict the worst-case 90-dBA noise contour. This contour is based on open-cut construction with the sources generating construction noise being located within street rights-of-way.Therefore,the 90-dBA contour would likely fall within the roadway right-of- way, resulting in less than significant impacts to noise-sensitive receptors. Rehabilitation of Western Regionol sewers, Project 3-64 3-190 3.9-Noise Noise-sensitive receptors most impacted by construction noise include numerous residential developments along the proposed Project corridors where replacement activities would occur. The following school in close proximity to the proposed Project would also experience temporary noise increases during construction: • Christ the King Elementary School — The nearest building is located south of Orangewood Avenue and approximately 300 feet east of Los Alamitos Boulevard and the Westside Relief Interceptor replacement improvements. Estimated maximum construction noise levels near this location would be approximately 82 dBA during the excavation phase.The nearest outdoor use is located further east and would be partially shielded by the school buildings. In addition, interior noise levels are anticipated to be substantially lower.Typical noise attenuation across a masonry building exterior ranges from 30 dBA (with open windows) to 35 dBA (with closed double-glazed windows).Therefore, noise impacts to the school would be less than significant. Build Alternative 2 Existing noise levels in the area of the Los Alamitos Sub-trunk and the Westside Relief Interceptor range from approximately 48 dBA to 78 dBA and 56 dBA to 76 dBA, respectively. Adding noise levels from construction of the proposed project to ambient conditions would generate temporary increases in ambient noise levels at or above 90 dBA mostly in the pipe replacement areas where open-trench construction would occur along the Los Alamitos Sub-trunk. Because the ultimate pipe location and construction method would not be determined until final design, Figure 3.9-2 through Figure 3.9-13 depict the worst-case 90-dBA noise contour. This contour is based on open-cut construction with the sources generating construction noise being located on both sides of the Project area; however, the preferred location is anticipated to be within the median. Therefore, the 90-dBA contour would fall within the roadway right-of-way, resulting in less than significant impacts to noise sensitive receptors. The noise-sensitive receptors most impacted by construction noise include numerous residential developments along the proposed Project corridors where replacement activities would occur. Several schools at the following locations within close proximity to the proposed Project would also experience temporary noise increases during construction: • Avalon—The nearest building is located west of Oak Street and approximately 30 feet west from the proposed Los Alamitos Sub-trunk replacement improvements. The estimated maximum construction noise levels at this location would be approximately 90 dBA during the excavation phase.Therefore, mitigation (NOI MM 1 and NOI MM 3), as described in Section 3.9.5 below, is required;and noise impacts to the school would be less than significant with mitigation. • International Elementary — The nearest building is located north of Cerritos Avenue and approximately 170 feet north from the proposed Los Alamitos Sub-trunk replacement improvements. The estimated maximum construction noise levels at this location would be approximately 87 dBA during the excavation phase. The nearest outdoor use is located further north and would be shielded by the school buildings. In addition, interior noise levels are Rehabilitation of Western Regional Sewers, Project 3-64 3-191 3.9-Noise anticipated to be substantially lower. Typical noise attenuation across a masonry building exterior ranges from 30 dBA (with open windows) to 35 dBA (with closed double-glazed windows).Therefore, noise impacts to the school would be less than significant. 3.9.4.8 Operational Impacts Following construction, only the potential operation of the air scrubber at the Westside Pump Station could result in a periodic increase in ambient noise levels.The air scrubber would be constructed within a new enclosure adjacent to the existing building, which would be designed to attenuate the overall noise, as discussed in Section 3.9.4.6.Therefore, operation of the proposed Project would not result in a substantial permanent increase in ambient noise levels. The operational noise would be less than significant. 3.9.4.9 No Bui/dAlternatfve Under the No Build Alternative, no rehabilitation or replacement of the Western Regional Sewers or improvements at the Westside Pump Station would occur other than routine operations and maintenance activities as discussed in Section 2.6. The No Build Alternative would have no impacts on people as a result of exceeding standards or excessive groundborne vibration. The No Build Alterative would not result in substantial or temporary increases in ambient noise. Noise impacts associated with the No Build Alternative would be less than significant. 3.9.5 Mitigation Measures NOI MM 1: OCSD will require the contractor to prepare a Noise Control Plan (NCP) demonstrating noise reduction, at minimum of 5 dBA to 10 dBA and below the 90-dBA Federal Transit Authority threshold, prior to commencing any construction. The NCP will specifically address noise control near sensitive receptors and for construction for which a variance has been obtained from the appropriate jurisdiction (e.g., weekend and nighttime construction). The NCP will identify the location of noise-sensitive receptors and list the types of noise control measures proposed (e.g., sound blankets and temporary noise barriers providing from 5 dBA to 23 dBA noise reduction) and any conditions specified in the variance. Once approved by OCSD,the contractor will be required to implement the plan. To ensure compliance with the NCP, the contractor will be required to monitor all construction noise for activities potentially affecting sensitive receptors in areas approved by variance, as well as all schools, hospitals, convalescent homes, churches, and other noise-sensitive areas within 1,000 feet of the construction activities. If construction activities take place during weekend and nighttime hours near sensitive receptors that have activities occurring on site during these times, coordination will be conducted with the site owners/managers to ensure adequate measures are taken to reduce or avoid noise impacts. Rehabilitation of Western Regional Sewers, Project 3-64 3-192 3.9-Noise NOI MM 2: The contractor will adhere to the specified hours in all local ordinances when construction activities are permitted". A variance will be required prior to construction if activities are planned to occur outside the permitted hours.OCSD will comply with any conditions specified in the variance. The following will minimize noise generated by all construction activities: • All construction equipment shall be maintained according to manufacturers specifications and inspected regularly. • All noise-producing construction equipment shall be equipped with muffling devices, quiet use generators, or other equivalent noise-reducing features to minimize temporary noise. • Stationary sources shall be located a minimum of 25 feet (the closest distance used to estimate construction noise impacts) from noise-sensitive receptors, unless otherwise constrained by site-specific conditions. • The use of noise-producing signals such as horns,whistles,alarms, bells,etc.shall be in accordance with federal,state,and local regulations. • Sound blankets and temporary sound barriers shall be located adjacent to construction activities where noise impacts above the regulated maximum levels are anticipated near noise sensitive receptors. NOI MM 3: The following will minimize vibration generated by all construction activities: • Route heavily loaded trucks away from residential local streets. • Operate earthmoving or other construction equipment with the potential to create vibration-induced impact as far away from vibration-sensitive sites as construction location-specific conditions allow. • Pile-driving equipment for shoring installation, if utilized, will be of a non-vibratory type, will have short starting and stopping capabilities and will be able to operate at high revolutions. In addition, soil particle velocity will be monitored during the use of such equipment. If any vibration levels are measured above the 0.20 IPS threshold level,construction will be stopped immediately. NOI MM 4: See NOI MM 1, NOI MM 2, NOI MM 3.and AES MM la. 3.9.6 Level of Significance after Mitigation Implementation of mitigation measures NOI MM 1, NOI MM 2, aad N01 MM 3 and NOI MM 4 would reduce noise and vibration levels during construction and operation; however, even with these 11 Except at Westside Pump Station,where construction hours would be reduced voluntarily by OCSD. Rehabilitation of Western Regional Sewers, Project 3-64 3-193 3.9-Noise measures, significant noise during construction, as identified in Impact NOI-4, would still occur. Impact NOI-4 is a significant and unavoidable impact.

Decibel Rehabilitation of Western Regional Sewers, Project 3-64 1. 3.10-Public Services 3.10 Public Services This section describes the existing public services in the proposed Project area and identifies potential impacts to those resources associated with the proposed Project's implementation.The requirement to consider impacts on public services is found within the California Environmental Quality Act (CEQA) and the Guidelines for Implementation of CEQA. Specifically, public services are included as a component of the general resource base that may be affected by a program or project(CEQA Guidelines Sec. 15126.2), as related to loss of essential public services under emergency conditions(CEQA Guidelines Sec. 15359), and as an element of the CEQA Checklist (Appendix G). Public services are defined in the CEQA Guidelines as including governmental facilities, acceptable service ratios, and response times. Specific public services covered in the CEQA Guidelines consist of fire protection, police protection, schools, parks,and other public facilities. 3.10.1 Existing Conditions Public Services within or adjacent to the Project area include the following: Xio.l.l Emergency Serpices: • Orange County Fire Station: 3131 North Gate Road,Seal Beach,CA 90740 The Orange County Fire Authority (OCFA) provides fire protection and emergency medical services response to the project area. Services include: structural fire protection, emergency medical and rescue services, hazardous response, and public education activities. OCFA also Participates in disaster Planning as it relates to emergency operations, which includes high occupant areas and school sites and may Participate in community disaster drills Planned by others. Fire Station 48, located at 3131 North Gate Road, Seal Beach Provides initial response to the Project area. Resources are deployed based upon a regional service delivery system, assigning personnel and equipment to emergency incidents without regard to jurisdictional boundaries.

Project impacts on public services would be significant under the following conditions: PSER-1: Would the project result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities, need for new or physically altered governmental facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times or other performance objectives for any of the following public services:fire protection, police protection,schools,parks,or other public facilities. 3.1O.3 Impact Analysis Both of the build alternatives would result in construction activities in the same locations. There are no substantive differences between the two build alternatives' locations from a public services perspective. With the exception of potential impacts to emergency vehicular access, the two build alternatives are similar and have the same level of significance findings,thus no differences between the alternatives are anticipated as they relate to impacts to public services. Therefore, the impacts described in this section are the same for Build Alternatives 1 and 2. Rehabilitation of Western Regional Sewers, Project 3-64 3-208 3.10-Public Services PSER-1: Would the project result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities, need for new or physically altered governmental facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times or other performance objectives for any of the following public services:fire protection, police protection,schools,parks,or other public facilities? 3.10.3•1 Construction Impacts The construction of the proposed Project would repair and replace existing pipelines. The proposed Project would not impact the surrounding community in the form of public services or increases in demand for schools or parks under either build alternative. Public use of select parks and roads may be restricted until construction is completed. No public facilities would be added; and, thus, increased population growth in these areas would have no potential to occur. The proposed rehabilitation or replacement of the Western Regional Sewers and proposed improvements at the Westside Pump Station could result in additional temporary areas of traffic congestion associated with staging and construction of the proposed Project within public street rights- of-way. Construction of the proposed Project could also result in disruption or delay of fire and police protection, potential delays for school buses or other vehicles transporting students to and from schools,and temporary relocation/closure of bus stops. The construction of either build alternative would affect emergency vehicular access within and through the proposed Project area. Build Alternative 2 would have proportionately greater impacts on Los Alamitos Boulevard, resulting in greater overall impacts on emergency access, as compared to Build Alternative 1. As a result, Build Alternative 2 would be expected to have a proportionately greater potential to affect emergency vehicular access,as compared to Build Alternative 1. As discussed in Transportation/Traffic (Section 3.12), traffic control plans (TCPs) would be submitted to the affected jurisdiction for approval. Orange County Sanitation District (OCSD) would contractually require that the TCPs specifically address construction traffic and road closures within the public rights- of-way of the Cities of Anaheim, Buena Park, Cypress, La Palma, Los Alamitos, and Seal Beach and the County of Orange. The traffic control plans would specify provisions for construction times and for allowance of bicyclists, pedestrians, and bus access throughout construction. The traffic control plans would also specify provisions to ensure emergency vehicle passage at all times, include signage and flagmen when necessary, and be approved by each affected city in advance of construction. Temporary relocation of bus stops or closure of bike lanes would be coordinated with OCTA service planning staff as required. Emergency access would be maintained throughout the duration of the proposed Project construction. Impacts related to emergency services and bus and school access,thus,would be less than significant under either build alternative. Rehabilitation of Western Regional Sewers, Project 3-64 3-209 3.10-Public Services Additionally, as described in Section 3.11 (Recreation), two parks (i.e., Denni Street Park and Willow Park), located adjacent to the project site, could experience temporarily reduced access due to construction; specifically, a reduction in parking near these facilities. It was determined that the remaining parks (Laurel Park, Evergreen Park, and Veterans Park) all have dedicated parking lots, and none would experience a reduction in access during construction. The ECMs identified in Table 2.10-1 would be incorporated.The proposed Project is not anticipated to result in a significant adverse impacts related to access to public facilities (e.g., parks); and, therefore, impacts would be less than significant under either build alternative. 3.10.3.2 Operatfonallmpaots Operations under either build alternative would consist of trips within the Project area to complete routine maintenance; clean sewer lines and manholes; perform visual inspection utilizing closed-circuit television and camera inspection; conduct flow-monitoring, as-needed repairs, and chemical dosing for odor and corrosion control; and operate the air scrubber if it is selected for the Project. Occasionally, some of these activities may also require temporary lane closures to accommodate sewer maintenance. Maintenance activities would be coordinated in advance with each jurisdiction to ensure appropriate preparation measures are taken to mitigate for temporary lane or road closures or restricted public use of certain areas. OCSD would comply with each corresponding jurisdiction's requirements for encroachment into the city streets (e.g., prepare traffic control plans, comply with Work Area Traffic Control Handbook,etc.).Operational impacts on public services would be less than significant. 3.10.3.3 No BuildAlternative Under the No Build Alternative, there would be no rehabilitation or replacement of the Western Regional Sewers or improvements at the Westside Pump Station other than operations and maintenance activities as discussed in Section 2.6. Occasionally, some of these activities may also require temporary lane closures to accommodate sewer maintenance. Maintenance activities would be coordinated in advance with each jurisdiction, for which OCSD would prepare traffic control plans for approval prior to any maintenance activities. Public services impacts associated with the No Build Alternative would be less than significant. 3.10.4 Mitigation Measures No mitigation measures are required. Rehabilitation of Western Regional Sewers, Project 3-64 3-210 3.11-Recreation 3.11 Recreation This section identifies the recreational resources in the Project area and the proposed Project's potential impacts on those recreation facilities. 3.11.1 Regulatory Setting 3.11.1.1 State California Public Park Preservation Act This act protects and preserves parkland in California. Under the California Public Resource Code, cities and counties may not acquire any real property that is in use as a public park for any non-park use unless compensation, land, or both are provided to replace the parkland acquired. This ensures that no net loss of parkland and facilities will occur. 3.11.1.2 Local CM of Cypress General Plan The City of Cypress General Plan Conservation/Open Space/Recreation Element (2000) provides goals and policies concerned with managing all open space areas, including undeveloped lands and outdoor recreation areas. The Recreation Element identifies planned park and recreation facilities designed to support the recreational needs of the City's population. The City has approximately 82 acres of parks, including community, neighborhood, mini, and nature parks. The following goal and policy apply within the proposed Project area. "Goal 6: Provide recreation/park facilities and programs for all those who live and work in Cypress. "Policy 6.8: Preserve public and private open space lands for active and passive recreational opportunities." City of La Palma General Plan The City of La Palma General Plan Open Space and Conservation Element provides direction to maintain and expand recreational opportunities and to protect environmental quality (City of La Palma 2014). Open space areas consist of community parks, utility easements, school playfields, and landscaping included in parkways, medians, and public spaces. The following goal and policy apply within the proposed Project area. "Goal 1: Develop and maintain parks, recreational, and cultural facilities that reflect the broadest range of interests and that meet the needs, desires, and interests of the La Palma community. "Policy 1-1: Maintain and improve existing parkland and recreation facilities, as the City budget permits" Rehabilitation of Western Regional Sewers, Project 3-64 3-211 3.11-Recreation City of Los Alamitos General Plan The City of Los Alamitos General Plan Open Space, Recreation, and Conservation Element provides direction to guide community members, staff, and elected officials to maintain and expand recreational opportunities and to protect environmental quality(City of Los Alamitos 2015).The City of Los Alamitos provides parks, school fields, and recreation facilities and programming that directly serve the residents of Los Alamitos, Rossmoor,Seal Beach,and Long Beach. 3.11.2 Existing Conditions Five parks or recreation areas are located adjacent to the proposed Project area:Willow Park, Evergreen Park,Veterans Park, Laurel Park,and Denni Street Park. 3.11.2.1 Denni Street Park Denni Street Park is located in the City of La Palma at the south end of Denni Street in a residential neighborhood. This park is adjacent to the existing Los Alamitos Sub-trunk and Westside Relief Interceptor pipeline that would have some portions replaced under Build Alternative 1 or would be entirely replaced under Build Alternative 2. The park is 0.3 acre and contains landscaped vegetation, including a grassy area,trees, and shrubs.This park connects to the Southern California Edison right-of- way easement located south of the park,which is also used as a multi-use trail that connects to Coyote Creek Bikeway. Denni Street Park has a play structure surrounded by a concrete sidewalk, as well as benches, picnic tables,and trash cans.This park does not contain a dedicated parking lot. 3.11.2.2 Evergreen Park Evergreen Park is located in the City of Cypress along Moody Street north of Orange Avenue in a residential neighborhood. Evergreen Park is adjacent to the Orange-West Sub-trunk Interceptor pipeline rehabilitation portion of both Project Build Alternatives 1 and 2. The park is 5.1 acres and contains landscaped vegetation, including a grassy area, trees, and shrubs. It has a picnic area, basketball court, grass athletic field with a backstop,and restrooms, as well as benches, picnic tables, concrete paths,and trash cans.This park contains dedicated parking lot accessible from Moody Street. 3.11.2.3 Laurel Park Laurel Park is located in the City of Los Alamitos at the northeast corner of the intersection of Katella Avenue and Bloomfield Street and adjacent to the Los Alamitos Elementary School. Laurel Park is adjacent to the existing Westside Relief Interceptor pipeline that would be replaced for Project Build Alternative 1 and rehabilitated for Project Build Alternative 2. It is located in a mix of commercial offices, light industrial, and community facilities. The park is 4.3 acres and contains landscaped vegetation, including a grassy area, trees, and shrubs. It has a picnic area, lighted multi-purpose field,tennis courts, and restrooms, as well as benches, picnic tables, and trash cans.This park contains dedicated parking lot accessible from Bloomfield Street. Rehabilitation of Western Regional Sewers, Project 3-64 3-212 3.11-Recreation 3.11.2.4 Veterans Park Veterans Park is located in a residential neighborhood in the City of Cypress at the northeast corner of the intersection of Ball Road and Denni Street. Veterans Park is adjacent to the Orange-West Sub-trunk Interceptor pipeline that would be rehabilitated for both Build Alternatives 1 and 2.The park is 6.4 acres and contains landscaped vegetation, including a grassy area,trees, and shrubs. It has a picnic area with a pavilion, skate park, basketball court, sand volleyball court, and restrooms, as well as benches, picnic tables,and trash cans.This park contains dedicated parking lot accessible from Avenida Granada. 3.11.2.5 Willour Park Willow Park is located in the City of Cypress at the northeast corner of Orange Avenue and Denni Street across from Lexington Junior High School and is generally located in a residential neighborhood. Willow Park is adjacent to the segment of the Orange-West Sub-trunk Interceptor pipeline that would be rehabilitated and the existing Los Alamitos Sub-trunk and the Westside Relief Interceptor pipelines that would be replaced for both Build Alternatives 1 and 2. The park is 2.9 acres and contains landscaped vegetation, including a grassy area, trees, and shrubs. It has a play structure, basketball court, restrooms, and a pond, as well as benches, picnic tables, and trash cans. This park does contain a dedicated parking lot. 3.11.3 Thresholds of Significance The following significance criterion is based on Appendix G of the California Environmental Quality Act (CEQA)Guidelines(14 California Code of Regulations 15000 et seq.) and is used to evaluate potential for significant Project impacts related to recreation. Project impacts on recreation would be significant if the proposed Project would: REC-1: Increase the use of existing neighborhood and regional parks or other recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated, or decrease access to parks or recreational facilities. Other impact significance criteria for recreation identified in Appendix G of the CEQA Checklist have been evaluated previously in Section 4.15 of the Initial Study for the proposed Project (See Appendix A). This previous evaluation determined that the proposed Project would result in either no impact or in less than significant impacts to recreation under these criteria. As a result, the following impact significance criterion has not been evaluated further within this EIR: Potential for the project to include recreational facilities or require the construction or expansion of recreational facilities which might have an adverse physical effect on the environment. Rehabilitation of Western Regional Sewers, Project 3-64 3-213 3.11-Recreation 3.11.4 Impact Analysis The differences between the two build alternatives are minor and have the same level of significance findings relative to the impact analysis for recreation.Thus,the impacts described in this section are the same for Build Alternative 1 and Build Alternative 2. REC-1: Would the project increase the use of existing neighborhood and regional parks or other recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated,or decrease access to parks or recreational facilities] 3.11.4.1 Construction Impacts Under either build alternative, the proposed Project would not increase the use of parks or other recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated. Additionally, construction activities would not occur within the boundaries of any parks or recreational areas or cause their closures. Five parks (Evergreen Park, Denni Street Park, Laurel Park, Veterans Park, and Willow Park) whose access could be temporarily reduced due to construction are located adjacent to the proposed Project site; specifically, park visitors could experience a reduction in parking near these facilities. The proposed Project would require lane closures for the replacement and/or rehabilitation of the pipelines and routine maintenance of sewage lines which could impact potential parking availability on streets near the above-mentioned parks. It was determined that Laurel Park, Evergreen Park, and Veterans Park all have dedicated parking lots; none would experience a reduction in access during construction because the replacement and/or rehabilitation of the pipelines would not encompass these areas.Additionally,the Westside Relief Interceptor sewer line rehabilitation work adjacent to Veterans Park would use the cured-in-place pipe (CIPP) construction method and would not require any open-cut construction. Thus, disruption from lane closures and routine maintenance near Veterans Park would be relatively low. Reconstruction of the Los Alamitos Sub-trunk sewer line near Denni Street Park and Willow Park could temporarily reduce access due to construction. The sewer line beneath the Denni Street Park needs to be reconstructed and would use trenchless technology (e.g., pipe bursting, micro tunneling, directional drilling, etc.) instead of open-cut construction to install the replacement sewer line. This method would minimize construction disturbance such as lane closures and routine maintenance and would prevent any construction from occurring within the park. However, construction along Denni Street near the park could reduce access to the park due to the equipment and entry/exit pit that may be required in Denni Street adjacent to the park. It should be noted that although street parking near Denni Street Park may be temporarily reduced during daytime hours, ample parking that enables access to the park is available along Denni Street and Robin Drive. Reconstruction of the Los Alamitos Sub-trunk sewer line near Willow Park along Denni Street would use open-cut construction requiring lane closures, which could reduce access to the park. Specifically, the lane closures could result in the temporary reduction of street parking along north- and southbound Denni Street between Orange Avenue and Newman Avenue. It should be noted that although street Rehabilitation of Western Regional Sewers, Project 3-64 3-214 3.11-Recreation parking along Denni Street near Willow Park may be reduced, ample parking at the nearby Lexington Junior High School to the west and A.E. Arnold Elementary School to the north would enable access to the park. Impacts from the proposed Project on park access and parking would be temporary, and disruptions would be short in duration (days to weeks). All of the identified parks would remain open, and impacts to access for these parks discussed above would be less than significant. 3.11.4.2 Operational Impacts Under either build alternative, most of the proposed Project elements would be located underground, except for the Westside Pump Station, where certain upgrade elements (e.g., air scrubber) would be located above ground. No operational impacts to recreational facilities are anticipated as a result of the proposed Project in relation to the sewer lines, manholes, or the Westside Pump Station. Moreover,the project would not induce growth or increase demand for park facilities. 3.11.4.3 No Build Alternative Under the No Build Alternative, there would be no rehabilitation or replacement of the Western Regional Sewers or improvements at the Westside Pump Station other than routine operations and maintenance activities as discussed in Section 2.6. The No Build Alternative would have no impacts on existing neighborhood and regional parks or other recreational facilities. 3.11.5 Mitigation Measures No mitigation measures are required. Rehabilitation of Western Regional Sewers, Project 3-64 3-215 3.13—Tribal Cultural Resources 3.12 Traffic and Circulation This section provides an overview of the existing transportation network; evaluates the potential impacts to traffic, transportation, and circulation that could result from the proposed Project; and identifies mitigation measures,as appropriate. 3.12.1 Regulatory Setting This section describes the applicable regulations pertaining to the transportation network within the proposed Project area. All work would require encroachment permits for work in city streets or within the California Department of Transportation (Caltrans) right-of-way(See Table 2.10-1 and Table 2.11-1). 3.12.1.1 Federal No applicable federal regulations address the transportation facilities or infrastructure within the proposed Project area. 3.12.1.2 State Streets and Hiehways Code Section 660 The California Department of Transportation (Caltrans) is the steward of the California state highway system. The safety of the traveling public, highway workers, and permittees is a primary concern. Caltrans also cooperates with other public agencies and with private parties to promote the safe use of state highways. An encroachment is defined in Section 660 of the California Streets and Highways Code as "any tower, pole, pole line, pipe, pipeline,fence, billboard, stand or building, or any structure, object of any kind or character not particularly mentioned in the section, or special event, which is in, under, or over any portion of the State highway right-of-way." An encroachment permit issued by Caltrans gives authority for the permittee to enter the state highway right-of-way to construct,alter, repair, improve facilities,or conduct specified activities. 3.12.1.3 Local Orange County's Congestion Management Program policy requires that intersections identified in the Orange County Transportation Authority (OCTA) Congestion Management Program Highway System maintain a level of service (LOS) grade of E or better (OCTA 2013; 5). If the LOS of a particular intersection falls below this, a deficiency plan must be developed; however, Congestion Management Program legislation specifies that construction, rehabilitation, or maintenance of facilities that impact the system shall be excluded from deficiency determinations [OCTA 2013: 14).

Class I bikeways are bike paths that are on a separate right-of-way from roadways and are usually shared by bicyclists and pedestrians. Class II bikeways are bike lanes that are on-street facilities that use painted stripes and stencils to delineate the rights-of-way assigned to bicyclists and motorists. Class III bikeways are bike routes that are signed on-street facilities that accommodate vehicles and bicycles in the same travel lane. In the vicinity of the Orange-Western Sub-trunk, Western Avenue between Santa Elena Drive and Del Monte Drive and Orange Avenue east of Holder Street and finishing at Holder Street is a designated bikeway(Class III). In the vicinity of the Westside Relief Interceptor, Denni Street between Ball Road and Cerritos Avenue is a designated bikeway (Class IIII and Moody Street between Crescent and Orange avenues, Orange Avenue between Moody and Denni streets, and Denni Street between Orange Street and Ball Road all provide bicycle lanes (Class II). In the vicinity of the Los Alamitos Sub-trunk designated bike routes (Class III) are on Bloomfield Street between Orange Avenue and Ball Road and on Cerritos Avenue between Bloomfield and Chestnut streets. In addition, bike lanes (Class II) are provided on Orange Avenue between Denni and Bloomfield streets and on Bloomfield Street between Ball Road and Cerritos Avenue. 3.12.2.6 Pedestrian Facilities In the Orange-Western Sub-trunk portion of the Project area, sidewalks are provided on both sides of the street for the duration of both Western and Orange avenues. In the Westside Relief Interceptor portion of the Project area, sidewalks are generally provided on both sides of the road except on Lexington Drive between Cerritos and Katella avenues where, for the first half, sidewalks are provided only on the east side of the road and,for the second half, sidewalks are provided only on the west side of the road. For the section of both the Westside Relief Interceptor and the Los Alamitos Sub-trunk on Rehabilitation of Western Regional Sewers, Project 3-64 3-224 3.13—Tribal Cultural Resources Old Ranch Parkway from Seal Beach Boulevard until the end of the proposed Project area, no sidewalks are on either side of the road. In the Los Alamitos Sub-trunk portion of the Project area, sidewalks are generally provided on both sides of the road.The exceptions are on Denni Street between Fontainbleau Way and Crescent Avenue,where only the east side of the road has a sidewalk, and on Guardian Drive between Crescent Avenue and Cypress Drive,where no sidewalks are on either side of the road. 3.12.2.7 Emergency Services Fire protection and emergency medical services in the proposed Project area are provided by the Orange County Fire Authority (OCFA). Four fire stations are located within the proposed Project area: OCFA Station#2, located southwest of the proposed Project area at 3642 Green Avenue in Los Alamitos; OCFA Station If 17, located south of the proposed Project area at 4991 Cerritos Avenue in Cypress; OCFA Station#63, located in the center of the proposed Project area at 9120 Holder Street in Buena Park; and OCFA Station # 61, located northeast of the proposed Project area at 8081 Western Avenue in Buena Park. Additionally, Long Beach Fire Department Station #5 is located adjacent to the proposed Project area to the west, and Los Angeles County Fire Department Station #34 is located adjacent to the proposed Project area to the north. Two medical centers with emergency rooms are located within the proposed Project area: Los Alamitos Medical Center, located at 3751 Katella Avenue, Los Alamitos, southwest of the Project area; and La Palma Intercommunity Hospital, located at 7901 Walker Street, La Palma, northeast of the Project area. 3.12.3 Thresholds of Significance The following significance criteria are based on Appendix G of the California Environmental Quality Act (CEQA) Guidelines (14 California Code of Regulations 15000 et seq.) and are used to determine the significance of potential traffic and circulation impacts. Impacts to traffic and circulation would be significant if the proposed Project would: TRANS-1: Conflict with an applicable plan, ordinance, or policy establishing measures of effectiveness for the performance of the circulation system, taking into account all modes of transportation including mass transit and non-motorized travel and relevant components of the circulation system, including but not limited to intersections, streets, highways and freeways, pedestrian and bicycle paths,and mass transit TRANS-2: Conflict with an applicable congestion management program, including, but not limited to, level of service standards and travel demand measures or other standards established by the county congestion management agency for designated roads or highways TRANS-3: Result in inadequate emergency access Other impact significance criteria for Traffic/Circulation, identified in Appendix G of the CEQA Checklist, have been evaluated previously in Section 4.16 of the Initial Study for the proposed Project (See Appendix A). This previous evaluation determined that the proposed Project would result in either no Rehabilitation of Western Regional Sewers, Project 3-64 3-225 3.13—Tribal Cultural Resources impact or in less than significant impacts to traffic and transportation under these criteria. As a result, the following impact significance criteria have not been evaluated further within this Environmental Impact Report(EIR): • Potential to result in a change in air traffic patterns, including either an increase in traffic levels or a change in location that results in substantial safety risks? • Potential to substantially increase hazards due to a design feature (e.g., sharp curves or dangerous intersections)or incompatible uses(e.g.,farm equipment)? • Potential to conflict with adopted policies, plans, or programs regarding public transit, bicycle, or pedestrian facilities,or otherwise decrease the performance or safety of such facilities? 3.12.4 Impact Analysis TRANS-1: Conflict with an applicable plan, ordinance, or policy establishing measures of effectiveness for the performance of the circulation system, taking into account all modes of transportation including mass transit and non-motorized travel and relevant components of the circulation system, including but not limited to intersections, streets, highways and freeways,pedestrian and bicycle paths, and mass transit? 3.12.4.1 Constructionimpacts As described in Section 2.5,the anticipated construction area necessary for replacement work would be up to 25 feet wide and 500 to 1,000 feet long.The anticipated construction area for rehabilitation work would involve two locations measuring 15 feet by 60 feet(at an upstream location) and 15 feet by 30 feet (at a downstream location). Manhole rehabilitation/replacement would result in some traffic disruption and driver inconveniences. Although lane closures are likely, full road closures on primary streets are not anticipated with either pipeline rehabilitation/replacement or manhole rehabilitation/replacement. On smaller streets or where other constraints occur, one-way traffic control and/or on-street parking restrictions may be required within the construction area.Additionally,construction on all major streets would occur during hours approved by the corresponding jurisdiction. It is anticipated that nighttime work may be required at certain times or in certain locations to reduce either traffic or other impacts; however,all nighttime work would require prior approval by the affected corresponding jurisdiction. Common Build Alternative Element Impacts In addition to the rehabilitation and/or replacement activities previously discussed for the Los Alamitos Sub-trunk and the Westside Relief Interceptor, both build alternatives would require rehabilitation of the Orange-Western Sub-trunk and the Seal Beach Blvd. Interceptor. They would also both require rehabilitation/replacement of the Westside Pump Station force main and wet well and the addition of either an air scrubber in a separate enclosure or an airjumper line. If the construction areas for the rehabilitation or replacement activities occupy Orange County Sanitation District's (OCSD) preferred location (inside lanes), access to bicycle lanes (see Section Rehabilitation of Western Regional Sewers, Project 3-64 3-226 3.13—Tribal Cultural Resources 3.12.2.5) and transit bus stops (see Section 3.12.2.4) within that area would not be affected. At this time, however, the new alignment of the replaced pipe is unknown. Because replacement may be required in the outside lanes, access to bicycle lanes and bus stops may be temporarily reduced during construction. However, as outlined below, where this is the case, any impacts would be reduced as part of the traffic control plan (TCP)process. It is a contractual requirement and a listed ECM that, as a part of the proposed Project, OCSD would require the contractor to prepare traffic control plans (TCPs). TCPs must be prepared by a licensed California Traffic Engineer. The TCPs would be submitted to the corresponding jurisdiction for review and approval. OCSD would contractually require that the TCPs specifically address construction traffic and necessary lane or road closures within the public rights-of-way of the Cities of Anaheim, Buena Park, Cypress, La Palma, Los Alamitos, and Seal Beach and the County of Orange. The TCPs would specify permissible construction times and ensure bicyclist, pedestrian, and bus access throughout construction through the use of signage and flagmen when necessary and temporary relocation of bus stops and detours of bike lanes and pedestrian walkways.The traffic control plans would also specify provisions to ensure emergency vehicle passage at all times, including the use of signage and flagmen when necessary to allow emergency vehicles to pass. Temporary relocation of bus stops would be coordinated with OCTA service planning staff as required to ensure no interruption of service. Temporary closure/detour of bike lanes would be coordinated with local jurisdictions as required. In preparing the TCP, the contractor would be required to consult with the affected school districts to ensure that specified construction times would have minimal impact on school access and activities. If deemed necessary during these consultations, construction times would be limited so that construction would not occur during school drop-off and pick-up times. The TCPs would also specify provisions to ensure pedestrian safety as well as school bus passage at all times, including the use of signage and flagmen immediately before, within and immediately after the construction zone as necessary for Pedestrian safety and to allow school busses to pass. Additionally, under both build alternative scenarios, rehabilitation activities associated with Seal Beach Blvd. Interceptor would encroach into Caltrans right-of-way for SR-22 and 1-405. Replacement and/or rehabilitation activities associated with the Westside Pump Station force main and the Los Alamitos Sub- trunk and rehabilitation activities associated with the Westside Relief Interceptor may also affect access to the freeway from Old Ranch Parkway. Work that would affect on-ramp access or would require encroachment into state highway right-of-way cannot occur without first obtaining approval from the Caltrans District 12 encroachments permit office. During final design, OCSD would obtain an encroachment permit, as required, for all work that could affect freeway operations or encroach within state highway right-of-way. The permitting process establishes terms and conditions under which the permittee is granted permissive authority to enter onto State right-of-way to perform construction-related activities. In order to obtain this permit,OCSD would have to establish to Caltrans through the application process that any construction activities ensure the safety of the traveling public, highway workers, and permittees; and protect, maintain, and enhance the quality of the state highway system during and after Rehabilitation of Western Regional Sewers, Project 3-64 3-227 3.13—Tribal Cultural Resources the permitted work in compliance with Caltrans requirements. This is done through the submittal of detailed plans outlining existing conditions and proposed construction work. Build Alternative 1 Both rehabilitation and replacement activities would encroach into traffic lanes and require temporary lane closures, parking restrictions, and nighttime construction to minimize traffic impacts at key project locations. Locations where pipeline replacement is required would result in the largest encroachment into traffic lanes and the greatest impacts to traffic. It should be noted that both rehabilitation and replacement activities are expected to require temporary lane closures within the construction area; however, as stated above, the TCPs would be required to ensure that local and business access is maintained at all times during construction. For the reasons outlined above, construction impacts on the effectiveness of the performance of the circulation system under Build Alternative 1 would be less than significant. Build Alternative 2 As outlined in Section 2.4.2.2, Build Alternative 2 would require construction of a second diversion structure at the intersection of Denni Street and Orange Avenue; and the Los Alamitos Sub-trunk would be replaced along its entire length. The Westside Relief Interceptor would be rehabilitated along its entire length. This would result in an additional replacement of approximately 19,080 linear feet of the Los Alamitos Sub-trunk. This means that the locations generally south of the intersection of Bloomfield Street and Cerritos Avenue along the Los Alamitos Sub-trunk (Cerritos Avenue, Chestnut Street, Sausalito Street, Oak Street, Katella Avenue, Los Alamitos Boulevard, Seal Beach Boulevard, and Old Ranch Parkway) would be subject to an increase in anticipated construction area associated with the replacement activities over rehabilitation activities as outlined above, with respect to the work on the Los-Alamitos Sub-trunk.This would be offset by the rehabilitation of approximately 16,010 linear feet of the Westside Relief Interceptor. This means that the locations generally south of the intersection of Denni Street and Myra Avenue (Denni Street, Lexington Drive, Katella Avenue, Los Alamitos Boulevard, Seal Beach Boulevard, and Old Ranch Parkway) would be subject to a decrease in anticipated construction area associated with rehabilitation activities over replacement activities. Further, the locations associated with both the Los Alamitos Sub-trunk and the Westside Relief Interceptor (Katella Avenue, Los Alamitos Boulevard, Seal Beach Boulevard, and Old Ranch Parkway) would alternately be subject to both replacement and rehabilitation activities. The result is an overall increase in pipe replacement of approximately 3,070 linear feet (approximately 3.5 percent of total pipeline to be replaced or rehabilitated). Additionally, as tabulated in Appendix B-1, Construction Details for Build Alternatives 1 & 2, the increased construction associated with pipeline replacement would result in an associated increase in construction time for pipeline replacement. The increased overall level of pipeline replacement under Build Alternative 2 would result in an increased number of total working days under this build Rehabilitation of Western Regional Sewers, Project 3-64 3-228 3.13—Tribal Cultural Resources alternative. As tabulated in Appendix B-1, Build Alternative 2 would result in an additional 140 total working days for the Los Alamitos Sub-trunk, due to increased pipeline replacement. This would be offset by a decrease of 65 total working days for the Westside Relief Interceptor due to the substitution of pipe replacement with pipe rehabilitation under this build alternative.This would result in a net total of an additional 75 working days for Build Alternative 2.This increase in working days would result in an increased impact on traffic under this build alternative,as compared to Build Alternative 1, by increasing both the duration of lane closures and the number of days that traffic levels within the Project area would be affected by construction-related trips. While Build Alternative 2 would result in an increase in construction area and construction duration,the measures outlined above would remain effective. For these reasons, and despite the differences outlined between Build Alternative 1 and Build Alternative 2, construction impacts on the effectiveness of the performance of the circulation system under Build Alternative 2 would still be less than significant. 3.12.4.2 Operational Impacts The operation of both build alternatives would be similar and consist of trips within the Project area to complete routine maintenance; clean sewer lines and manholes; perform visual inspection utilizing closed-circuit television and camera inspection; conduct flow-monitoring, as-needed repairs, and chemical dosing for odor and corrosion control; and operate the air scrubber if it is selected for the proposed Project. Occasionally, these activities would also require temporary lane closures to accommodate sewer maintenance. Such operational impacts are already part of the baseline conditions due to existing ongoing sewer maintenance. Maintenance activities would be coordinated in advance with each corresponding jurisdiction.OCSD would comply with each affected jurisdiction's requirements for encroachment into the city streets(e.g., prepare traffic control plans, comply with Work Area Traffic Control Handbook, etc.) in order to ensure minimal impact on traffic circulation. Operation impacts on effectiveness of the performance of the circulation system would therefore be less than significant. TRANS-2: Conflict with an applicable congestion management program, including, but not limited to, level of service standards and travel demand measures or other standards established by the county congestion management agency for designated roads or highways? 3.12.4.3 Construction Impacts Two Congestion Management Program roadways are within the proposed Project area, Valley View Boulevard and Katella Avenue. Construction on all Congestion Management Program roadways would be completed outside AM (6:00 a.m.to 9:00 a.m.) and PM (3:00 p.m.to 7:00 p.m.) peak hours.Through the process of developing traffic control plans as part of the construction effort, it may be determined through that review process that construction is required outside of peak hours. As noted in the ECMs shown in Table 2.10-1, the contractor would be contractually required to implement a Traffic Control Plan (TCP)which,among other things,would specify permissible construction times to ensure continued Rehabilitation of Western Regional Sewers, Project 3-64 3-229 3.13—Tribal Cultural Resources vehicular and pedestrian access based upon the specific jurisdictional requirement. Based on these ECMs, potential impacts would be less than significant. Common Build Alternative Element Impacts Both build alternatives would require construction activities on Katella Avenue associated with both the Los Alamitos Sub-trunk and the Westside Relief Interceptor. As shown in Section 2.10, Environmental Control Measures (Table 2.10-1, Traffic and Circulation) OCSD would contractually prohibit concurrent construction for the Westside Relief Interceptor and the Los Alamitos Sub-trunk on Katella Avenue. The Orange-Western Sub-trunk ends at the intersection of Valley View Boulevard and Orange Avenue. Orange Avenue is a four-lane roadway. Both build alternatives require rehabilitation of the Orange- Western Sub-trunk along its entirety. As described in Section 2.5, Construction, rehabilitation activities have a lower anticipated construction area than replacement activities. Even if closure of one lane is required for the final section of rehabilitation on Orange Avenue leading up to Valley View Boulevard, the disparity in annual average daily traffic volumes, as shown in Table 3.12-2, indicates that this rehabilitation work would have little if any impact on traffic on Valley View Boulevard. Table 3.12-3 shows the four Congestion Management Program intersections within the vicinity of the proposed Project area. OCTA policy requires that Congestion Management Program intersections maintain at least LOS E or higher, otherwise, a deficiency plan must be devised. The 2015 baselines during both AM and PM peak periods are all LOS E or better. Further, OCTA policy indicates that construction activities are excluded from deficiency determinations. In addition, the proposed Project would require TCP approval for work on all roadways, including Congestion Management Program roadways,which would ensure that any impact to circulation is mitigated. Build Alternative 1 Under Build Alternative 1, Katella Avenue would be subject to replacement activities, as outlined in Section 3.12.4.1,for the Westside Relief Interceptor from the intersection of Los Alamitos Boulevard to Lexington Drive and to rehabilitation activities, as outlined in Section 3.12.4.1, associated with the Los Alamitos Sub-trunk from the intersection of Los Alamitos Boulevard to Oak Street. Build Alternative 1 replaces approximately 5,300 linear feet of pipeline along Katella Avenue and rehabilitates approximately 1,250 linear feet of pipeline.This would result in an overall anticipated construction area of approximately 151,250 square feet. For the reasons outlined above, any impacts on the Congestion Management Program under Build Alternative 1 would be less than significant. Build Alternative 2 Under Build Alternative 2, Katella Avenue would be subject to rehabilitation activities, as outlined in Section 3.12.4.1, for the Westside Relief Interceptor from the intersection of Los Alamitos Boulevard to Lexington Drive and by replacement activities, as outlined in Section 3.12.4.1, associated with the Los Rehabilitation of Western Regional sewers, Project 3-64 3-230 3.13—Tribal Cultural Resources Alamitos Sub-trunk from the intersection of Los Alamitos Boulevard to Oak Street. Build Alternative 2 replaces approximately 1,250 liner feet of pipeline along Katella Avenue and rehabilitates approximately 5,300 linear feet along Katella Avenue. This would result in an overall anticipated construction area of approximately 79,500 square feet. Compared to Build Alternative 1, this alternative would result in an overall decrease in anticipated construction area of 71,750 square feet due to the overall increase in rehabilitation activities,which have a smaller anticipated construction zone.This decrease in anticipated construction area results in is a lower potential for impact on Katella Avenue from encroachment into traffic under Build Alternative 2; however, proportionately greater impacts occur on Los Alamitos Boulevard under Build Alternative 2, resulting in greater overall traffic impacts under Build Alternative 2 as compared to Build Alternative 1. For the reasons outlined above, and despite the differences outlined between Build Alternative 1 and Build Alternative 2, any impacts on the Congestion Management Program under Build Alternative 2 would be less than significant. 3•12.4.4 Operational Impacts The operation of both build alternatives would be similar and consist of trips within the Project area to complete routine maintenance; clean sewer lines and manholes; perform visual inspection utilizing closed-circuit television and camera inspection; conduct flow-monitoring, as-needed repairs, and chemical dosing for odor and corrosion control; and operate the air scrubber if it is selected for the proposed Project. Occasionally, some of these activities may also require temporary lane closures to accommodate sewer maintenance. It should be stated that these operational impacts are already part of the baseline conditions due to existing ongoing sewer maintenance. As noted in Section 3.12.4.2, operational differences between the two build alternatives would be negligible. Maintenance activities would be coordinated in advance with each jurisdiction. OCSD would comply with each affected jurisdiction's requirements for encroachment (e.g., prepare traffic control plans,comply with Work Area Traffic Control Handbook, etc.) prior to any encroachment. OCSD would prepare traffic control plans for approval prior to any maintenance activities on Congestion Management Program roadways. Operation impacts on Congestion Management Program roadways or the Congestion Management Program system would be less than significant. TRANS-3: Result in inadequate emergency access? 3.12.4.5 Construction Impacts The construction of either build alternative would affect emergency access within and through the proposed Project area. As discussed above, however, Build Alternative 2 would have proportionately greater impacts on Los Alamitos Boulevard, resulting in greater overall traffic impacts under Build Alternative 2, as compared to Build Alternative 1. As a result, Build Alternative 2 would be expected to have a proportionately greater potential to affect emergency access,as compared to Build Alternative 1. Rehabilitation of Western Regional Sewers, Project 3-64 3-231 3.13—Tribal Cultural Resources The potential effects on emergency access within and through the proposed Project area associated with the construction area for rehabilitation or replacement of the pipelines, as described under TRANS-1, include: Would encroach into traffic lanes and may require temporary lane and/or street closures;parking restrictions and, potentially, nighttime construction to minimize traffic impacts during the day. As described under TRANS-1, it is a contractual requirement and a listed ECM that, as part of this project, OCSD would require the contractor to prepare TCPs. TCPs must be prepared by a licensed California Traffic Engineer and would be submitted to the affected jurisdiction for approval.OCSD would contractually require that the TCPs specifically address construction traffic and road closures within the public rights-of-way of the Cities of Anaheim, Buena Park, Cypress, La Palma, Los Alamitos, and Seal Beach and the County of Orange. The traffic control plans would also specify provisions to ensure emergency vehicle passage at all times and include signage, flagmen, or any other means necessary to maintain emergency access within and through the construction area.The Orange County Fire Authority Emergency Communications Center would be notified of construction days and times. Prior to any construction that may result in delay of emergency response services to the public. In Preparing the TCP, the contractor would be required to consult the relevant School District so that specified construction times would have minimal impact on school access and activities. If deemed necessary during these consultations, construction times would be limited so that construction would not occur during school drop-off and Pick-up times. The TCPs would also specify Provisions to ensure Pedestrian safety as well as school bus Passage at all times, including the use of signage and flagmen immediately before, within and immediately after the construction zone as necessary for pedestrian safety and to allow school busses to pass. The proposed Project would result in less than significant impacts on emergency access within and through the Project area. Implementation of the proposed Project would entail nighttime (typically after 7:00 p.m. or 8:00 p.m. until 6:00 a.m. or 7:00 a.m.,as defined by the applicable cities' noise ordinances)construction in various locations in order to minimize disruption to traffic. An example of such an occurrence would be construction activities at major intersections. Construction activities at such times may conflict with local plans, ordinances, or requirements pertaining to nighttime lighting and noise. Adherence to the Traffic and Circulation ECNIs identified in Table 2.10-1 and coordination with pertinent jurisdictional authorities would result in less than significant impacts. Build Alternative 1 Build Alternative 1 would require a mixture of rehabilitation and replacement activities along both the Los Alamitos Sub-trunk and the Westside Relief Interceptor.As outlined in Section 3.12.4.1, areas where pipeline replacement is required have a greater potential to encroach into traffic lanes due to an increased anticipated construction area. As such, the locations subject to replacement along the Los Alamitos Sub-trunk (Denni Street, Orange Avenue, and Bloomfield Street) and the Westside Relief Interceptor (Denni Street, Lexington Drive, Katella Avenue, Los Alamitos Boulevard, Seal Beach Boulevard,and Old Ranch Parkway)would have a greater potential to encroach into traffic lanes. Rehabilitation of Western Regional Sewers, Project 3-64 3-232 3.13—Tribal Cultural Resources For the reasons outlined above, any impact on emergency access under Build Alternative 1 would be less than significant. Build Alternative 2 As outlined in Section 2.4.2.2, Build Alternative 2 would require construction of a second diversion structure at the intersection of Denni Street and Orange Avenue; and the Los Alamitos Sub-trunk would be replaced along its entire length. The Westside Relief Interceptor would be rehabilitated along its entire length. As outlined in Section 3.12.4.1, this would mean an overall increase in pipeline replacement of 3,070 linear feet under Build Alternative 2, resulting in an increase in the potential encroachment into traffic lanes under this build alternative due to the increased anticipated construction zone. Additionally, as discussed in Section 3.12.4.1, the increased construction associated with the increased overall levels of pipeline replacement under Build Alternative 2 would lead to an increase of 75 total working days. This would have a greater impact on emergency access due to the increased duration of lane closures and the increased number of days that traffic levels within the Project area would be affected by construction-related trips. While an increase in construction area and construction duration under this build alternative would affect emergency access, the measures outlined above would remain effective. For these reasons, and despite the differences outlined between Build Alternative 1 and Build Alternative 2, any impact on emergency access under Build Alternative 2 would be less than significant. 3.12.4.6 Operational Impacts The operation of both build alternatives would be similar and consist of trips within the Project area to complete routine maintenance; clean sewer lines and manholes; perform visual inspection utilizing closed-circuit television and camera inspection; conduct flow-monitoring, as-needed repairs, and chemical dosing for odor and corrosion control; and operate the air scrubber, if it is selected for the proposed Project. Occasionally, some of these activities would require temporary lane closures to accommodate sewer maintenance. These operational impacts are already part of the baseline conditions due to existing ongoing sewer maintenance. Maintenance activities would be coordinated in advance with each jurisdiction. OCSD would comply with each affected jurisdiction's requirements for encroachment into the city streets (e.g., prepare traffic control plans, comply with Work Area Traffic Control Handbook, etc.), a component of which would require maintenance of local and emergency access at all times, prior to any encroachment into city streets. Operation impacts on emergency access would be less than significant. 3.12.4.7 No Build Alternative Under the No Build Alternative, no rehabilitation or replacement of the Western Regional Sewers or improvements at the Westside Pump Station would occur other than operations and maintenance activities as discussed in Section 2.6. Occasionally, some of these activities may also require temporary Rehabilitation of Western Regional Sewers, Project 3-64 3-233 3.13—Tribal Cultural Resources lane closures to accommodate sewer maintenance. Maintenance activities would be coordinated in advance with each jurisdiction,for which OCSD would prepare traffic control plans for approval prior to any maintenance activities. Traffic and circulation impacts associated with the No Build Alternative would be less than significant. 3.12.5 Mitigation Measures No mitigation measures are required. 3.13 Tribal Cultural Resources This section identifies tribal cultural resources alone the alignment for the Proposed Project area, the significance of those resources, and addresses Potential impacts to those resources. Under California Assembly Bill 52 (AB 521, tribal cultural resources generally include sites, features, places, cultural landscapes,sacred places and objects with cultural value to a California Native American tribe(California Public Resources Code 4 21074). This analysis has been prepared in accordance with CEQA Guidelines, Section 15064.5, and is supported by the Cultural Resources Constraints Report(see Appendix C). 3.13.1 Regulatory Setting The proposed Project is undertaken in compliance with regulatory standards set forth by CEQA. the California Public Resources Code.the California Health and Safety Code, and the Orange County General Plan and,where applicable,standards set forth by municipalities within the Project area. 3.13.1.1 California Enaironmental Quality Act Proposed project plans are subject to CEQA analysis as it pertains to cultural resources; and lead agencies or Proiect proponents, such as OCSD, are required to comply with the CEQA Statute and Guidelines (as amended through 2016) by determining if the project will cause a substantial adverse change in the significance of a "historic resource." as defined in Title 14 of the California Code of Regulations 415064.5(al. For CEQA Purposes, a cultural resource is considered a historical resource if the resource is 50 years old or older: possesses integrity of location, design, setting, materials, workmanship, feeling, and association: and meets the requirements for listing on the California Register of Historical Resources (CRHR) including(Title 14,California Code of Regulations. 4 15064.5): (1) Is associated with events that have made a significant contribution to the broad patterns of California's history and cultural heritage (2) Is associated with the lives of Persons important in our oast (3) Embodies the distinctive characteristics of a type, period, region, or method of construction, or represents the work of an important creative individual,or possesses high artistic value Rehabilitation of Western Regionol Sewers, Project 3-64 3-234 3.13—Tribal Cultural Resources (4) Has yielded,or may be likely to yield,information important in Prehistory or history Additionally, the CRHR consists of resources that are listed automatically and those that must be nominated through an application and public hearing process. The CRHR automatically includes the following(California Public Resources Code§5024.1(dl): • California properties listed on the National Register and those formally Determined Eligible for the NRHP • California Registered Historical Landmarks from No. 770 onward • Those California Points of Historical Interest that have been evaluated by the Office of Historic Preservation and have been recommended to the State Historical Commission for inclusion on the CRHR Other resources that may be nominated to the CRHR include: • Historical resources with a significance rating of Category 3 through 5 (Those properties identified as eligible for listing on the National Register. the CRHR, and/or a local jurisdiction register) • Individual historical resources Historical resources contributing to historic districts • Historical resources designated or listed as local landmarks, or designated under any local ordinance,such as a historic preservation overlay zone The fact that a resource is not listed in or determined eligible for listing in the CRHR, or is not included in a local register of historical resources, does not preclude a lead agency from determining that the resource may be a historical resource(Title 14,California Code of Regulations 15064.5(a1(41). 3.13.1.2 State of California Health and Safety Code The California Health and Safety Code Section 7050.5(b) specifies protocol when human remains are discovered. Specifically, burials or human remains found outside a known cemetery are not to be disturbed or removed unless by authority of law. The area of a discovery of human remains should remain undisturbed until a County coroner is notified and has examined the remains prior to determining the appropriate course of action within two days of notice. The County coroner will notify the Native American Heritage Commission (NAHC) within 24 hours should the remains be found to be those of a Native American. 3.13.1.3 California Senate Bill 18 Senate Bill 18 was signed into law in September 2004 and went into effect on March 1. 2005, as California Government Code Sections 65352.3 et sea. It placed new requirements upon local Rehabilitation of Western Regional Sewers, Project 3-64 3-235 3.13—Tribal Cultural Resources governments for developments within or near Traditional Tribal Cultural Places (TTCP). The law instituted a new process which would reauire a city or county to consult with the NAHC and any appropriate Native American tribe for the purpose of preserving TTCPs prior to the adoption, revision, amendment,or update of a city's or county's general plan.TTCPs require a traditional association of the site with Native American traditional beliefs, cultural practices, or ceremonies: or the site must be shown to actually have been used for activities related to traditional beliefs, cultural practices, or ceremonies. 3.13•1•4 California Assembly Bills Assembly Bill 52 (AB 52) went into effect on July 1. 2015, to amend Section 5097.94 of the California Public Resources Code and to add Sections 21073, 21074, 21080.3.1, 21080.3.2, 21082.3, 21083.09, 21084.2, and 21084.3 of the California Public Resources Code. AB 52 requires consultation with the NAHC Native AMPNFAn HPF -- and Tribal governments to identify and address potential adverse impacts to tribal cultural resources. As per the California Public Resources Code Section 21094.2, "a project with an effect that may cause a substantial adverse change in the significance of a tribal cultural resource is a proiect that may have a significant effect on the environment."The California Public Resources Code requires a lead agency or project proponent to consult with California Native American tribes that request consultation and are traditionally and culturally affiliated with the geographic area of a proposed proiect. The consultation is required for a negative declaration or negative declaration with mitigation.The lead agency or project proponent must take into consideration the impacts to tribal cultural resources and any measures to mitigate such impacts, if any.The California Public Resources Code defines "Tribal cultural resources" as sites, features, places, cultural landscapes, sacred places, and objects with cultural value to a California Native American tribe that are either of the following(California Public Resources Code 4 21074(al): (1) Included or determined to be eligible for inclusion in the CRHR (2) Included in a local register of historical resources as defined in subdivision (k) of Section 5020.1 The NAHC will provide each tribe with a list of all public agencies that may be lead agencies under CEOA within their geographic areas. If a tribe wishes to be notified of projects by the relevant lead agencies, they must submit a written request.Within 14 days of a project application,the lead agency must notify. in writing,the tribes that have requested notification of proposed projects and must state that the tribe has 30 days to reauest consultation. The lead agencies must begin the consultation process with the tribes that have requested consultation within 30 days of receiving the request. The consultation concludes when the parties agree to measures to mitigate or avoid impact, if any, on tribal resources:or a party, in good faith and after reasonable effort, determines that mutual agreement cannot be reached (California Public Resources Code Section 21080.3.21. Rehabilitation of Western Regionol sewers, Project 3-64 3-236 3.13—Tribal Cultural Resources According to CUL MM 8: Should any tribal entity identified on the �� CemmivAj NAHC contact list reauest on-site monitoring during construction of particular segments of the Project area out of concern for potential impacts to known or unanticipated tribal resources. OCSD spal4woulrlprovide a tribal approved Native American monitor/liaison. Sections of the Project area that may require such monitoring are contingent upon engineering design specifics which have vet to be finalized. On March 9. 2016. the Juaneno Band of Mission Indians replied to OCSD by phone and requested to have one of their monitors present during ground-disturbing activities along the Seal Beach Boulevard segment of the alignment. On November 2. 2016.the Gabrieleno Band of Mission Indians— Kizh Natio requested one of their experienced and certified Native American monitors be on site during any and al around disturbances (indudine but not limited to pavement removal, pot-holing or auguring. bovine. grading, excavation and trenching). OCSD would consult with the tribes and provide for a tribal approved Native American monitor/liaison during construction in accordance with CUL MM 8. Refer to section 3.4 Cultural Resources for further details on OCSD's tribal consultations and the affected local jurisdictions in the proposed Proiect's vicinity:Orange County.City of Anaheim.City of Buena Park. City of La Palma. City of Los Alamitos.and City of Seal Beach. 3.13.2 Existing:Conditions 3.13.2.1 Cultural History Historical Background A summary of the historical background of the region is in section 3.4 Cultural Resources to present the cultural context of the proposed Project area. For a more in-depth history of the region, refer to the Cultural Constraints Report in Appendix C(Kay 2015). 3.13.2.2 Rxisting Resources A cultural resources records search and survey encompassing areas of both build alternatives was completed.The records searches, conducted at the South Central Coastal Information Center on June 9. 2015 and October 7. 2015, accounted for previous investigations and previously-documented cultural resources within the Project area and a 1/8-mile buffer(Figure 3.4-1). The results of the records search are presented in the Cultural Constraints Report (Appendix C). A review of the records at California Historical Resources Information System indicated no historical resources and two archaeological resources in the Project area. Both of these resources are addressed in Section 3.4.4.3. The records search conducted at the South Central Coastal Information Center revealed that two Previously documented sites intersect the proposed Project area: P-30-001352 and P-30-001502. These sites still maintain potential for archaeological resources. Rehabilitation of Western Regionol Sewers, Project 3-64 3-237 3.13—Tribal Cultural Resources Site P-30-001352 was described as a secondary marine shell deposit encompassing 10.000 square 40 meters. The southern half of the site was destroyed by the construction of Interstate (1-1 5, and the northern half has since been built over with a parking lot and corporate buildings.As the site's materials were reported to have originated from elsewhere (i.e., introduced) and have been disturbed since, the site has lost integrity and historical context and is not eligible for any historic registers. Site P-30-001502 was first documented in 1999 as a scatter of prehistoric artifacts. The site is reported to be adjacent to and east of the Seal Beach Blvd. Interceptor alignment along Seal Beach Boulevard, within the United States (U.S.) Naval Weapons Support Facilities. and was reported to have been disturbed by the development of the Orange County Flood Control Channel.The westernmost boundary of the site is within the proposed Proiect area and was likely disturbed by the construction of the existing road (Seal Beach Boulevard). The last investigation of this site in 2010 by URS archaeologists reported the presence of prehistoric archaeological materials in areas that had not been disturbed. These areas are outside the Proposed Project area. Any agency, organization, individual, or other entity can nominate a resource to the CRHR through the Nomination Packet,alone with the California Department of Parks and Recreation Form 523 (completed for this study).The local government in whose jurisdiction the resource is located should be notified by certified mail that an application will be filed with the State Historic Preservation Officer(SHPO)and that the local government should provide written comments within 90 days. The application and comments are to be submitted to the SHPO for review,and a determination is made in regard to the site's eligibiliri on the CRHR. For nomination to the NRHP,the process includes additional applications submitted to the National Park Service, initiating a process that requires the same process of review, notification to property owners and local governments, and public review and comments. The process is undertaken through the SHIM The application is submitted by the state to the National Park Service in Washington. D.C. for final review and, if approved, listing by the Keeper of the NRHP. The National Park Service makes a listing decision on the NRHP within 45 days. The proposed Project alignment for the Los Alamitos Sub-trunk alone Guardian Drive is immediately adjacent to several hundred interment markers or memorial tablets. The memorial tablets on the east side of Guardian Drive, located in an area called 'The Sheltering Trees." are less than 2 feet from the Project area: and their orientation indicates that the interments are parallel to the Project area. The tablets on the west side, located in the "Garden of Protection:' are less than 7 feet away from the Project area and appear to be perpendicular to the Project area. 3-13.3 Thresholds of Significance The following significance criteria are based on Appendix G of the CEQA Guidelines (14 California Code of Regulations 15000 et seal and are used to evaluate the potential for significant project impacts Rehabilitation of Western Regionol sewers, Project 3-64 3-238 3.13—Tribal Cultural Resources related to cultural resources". Proiect impacts on cultural resources would be significant if the proposed Project would: TRI CUL-1: Cause a substantial adverse change in the significance of a tribal cultural resource, defined in Public Resources Code Section 21074 as either a site, feature, place, cultural landscape that is geographically defined in terms of the size and scope of the landscape, sacred place, or object with cultural value to a California Native American tribe, and that is listed or eligible for listing in the California Register of Historical Resources, or in a local register of historical resources as defined in Public Resources Code section 5020.1(k). TRI CUL-2: Cause a substantial adverse change in the significance of a tribal cultural resource, defined in Public Resources Code Section 21074 as either a site, feature, place, cultural landscape that is geographically defined in terms of the size and scope of the landscape, sacred olace, or object with cultural value to a California Native American tribe, and that is a resource determined by the lead agency, in its discretion and supported by the substantial evidence, to be significant Pursuant to criteria set forth in subdivision ( c 1 of Public Resources Code Section 5024.1. In applying the criteria set forth in subdivision ( c 1 of Public Resource Code Section 5024.1.the lead agency shall consider the significance of the resource to a California Native American tribe. 3.13.4 Impact Analysis TRI CUL-1.

In ra Please note: Since the publication and circulation of the ISINOP recently adopted legislative amendments to the CEOA Checklist have created a separate Tribal Cultural Resource impact category. The significance question contained in the revised checklist is. "Have California Native American tribes traditionally and culturally affiliated with the pro ea area requested consultation Pursuant to Public Resources Code section 23080.3.1?If so,has consultation begun?"As discussed in Section 3.4.4.3 Construction Impacts.consultation with Native American Tribes has been initiated(See Appendix AI and, to date,two tribes have expressed interest in the Proiect.OCSD would provide for the Presence of a stnbal on-site monitor in response to AB 52 consultations.Thus the Draft EIR the letter and intent of the amended CEOA Checklist. Rehabilitation of Western Regional Sewers, Project 3-64 3-239 3.13—Tribal Cultural Resources addition, both build alternatives would entail rehabilitation of the Orange-Western Sub-trunk and Seal Beach Blvd. Interceptor pipelines using trenchless cured-in-place pipe (CIPP) methods. Further, portions of the existing Westside Relief Interceptor sewer pipe would be rehabilitated in place using trenchless CIPP methods under both build alternatives. Manholes associated with these pipelines would be replaced or rehabilitated,as appropriate. Build Alternative 1 Build Alternative 1 is located within oaved public rights-of-ways within city streets or OCSD easements. A cultural resources records search and survey encompassing areas of both build alternatives was completed (see Figure 3.4-1). A review of the records at California Historical Resources Information System indicated no historical resources, other than Forest Lawn Memorial Park,and two archaeological resources in the Project area. Both of these archaeological resources are described in Section 3.4.4.3. As described under Section 3.13.4.2, Build Alternative 1 is anticipated to have a less than significant potential impact to archaeological resources. Based on the results of the records search. the Project would not intersect any previously recorded resources. Furthermore,the field survey resulted in no new discovery of archaeological resources.The potential to adversely impact undiscovered cultural resources is unknown but potentially significant: however, implementation of CUL MM 1, CUL MM 7,and CUL MM 8 would reduce these potential impacts to less than significant(see Section 3.4.51. Build Alternative 2 Build Alternative 2 was developed after the records search for Build Alternative 1 was completed. Because the horizontal extent of Alternative 2 is anticipated to be the same as Alternative 1, the results of the records search and the field survey remain applicable to the proposed specifications of Build Alternative 2. A review of the records at California Historical Resources Information System indicated no historical resources,other than Forest Lawn described above,and two archaeological resources within the Proiect area. Both of these archaeological resources are described in Section 3.4.4.3. As described under Section 3.13.4.2. although Build Alternative 2 would result in approximately 3,070 linear feet of additional open-cut trenching compared to Build Alternative 1 it is anticipated to have a less than significant potential impact to archaeological resources. Based on the results of the records search.the Project would not intersect any Previously recorded resources. Furthermore,the field survey resulted in no new discovery of archaeological resources. The potential to adversely impact undiscovered cultural resources is unknown but potentially significant: however, implementation of CUL MM 1. CUL MM 7. and CUL MM 8 would reduce these potential impacts to less than significant (see Section 3.4.5). TRI CUL-2.

In applying the criteria set forth in subdivision Ic1 of Public Resource Code Section 5024.1, the lead agency shall consider the significance of the resource to a California Native American tribe? 3.13.4.2 Constructionhrtpacts Common Build Alternative Element Impacts Both Build Alternatives 1 and 2 would entail rehabilitation or replacement of the Westside Pump Station force main and wet well, as well as installation of an air scrubber or air jumper line for odor control. In addition, both build alternatives would entail rehabilitation of the Orange-Western Sub-trunk and the Seal Beach Blvd. Interceptor pipelines using trenchless CIPP methods. Further, under both build alternatives, portions of the existing Westside Relief Interceptor sewer pipe would be rehabilitated in place using trenchless CIPP methods. Manholes associated with these pipelines would be replaced or rehabilitated, as appropriate. The records search conducted for the proposed Project indicated that the proposed alignment falls within,or adiacent to,two previously disturbed archaeological sites: P-30-001352 and P-30-001502.Site P-30-001352 was destroyed by the construction of 1-405, and the western portion of P-30-001502 was destroyed by the construction of Seal Beach Boulevard and the Orange County Flood Control Channel. The remaining portions of P-30-001502 are on inaccessible property owned by the United States Navy and would not be impacted by the Proiect's construction activities. Furthermore,the field survey did not identify any newly discovered archaeological resources within the Project area. Therefore, the impacts of these common build alternative elements are less than significant in those areas where archaeological resources have been identified. Nevertheless, as the Project calls for open-cut trenching down to depths of up to 18 feet bgs alone portions of the Project alignment, the possibility remains that archaeological resources that have vet to be identified or documented may be encountered.The results of the records searches and surveys are based on resources that were exposed on or near the surface; but this does not exclude the possibility of subsurface deposits at lower depths, particularly in areas comprising native or undisturbed soils. In this situation, the potential to adversely impact undiscovered cultural resources is unknown but Potentially significant: however, implementation of CUL MM 1,CUL MM 7. and CUL MM 8 would reduce these potential impacts to less than significant. Build Alternative 1 Build Alternative 1 would replace portions of the existing Los Alamitos Sub-trunk and the Westside Relief Interceptor with new, larger capacity pipe. This build alternative also would rehabilitate Portions of the existing Los Alamitos Sub-trunk and the Westside Relief Interceptor sewer pipe in place. In Rehabilitation of Western Regional Sewers, Project 3-64 3-241 3.13—Tribal Cultural Resources addition. Build Alternative 1 would rehabilitate the Orange-Western Sub-trunk and the Seal Beach Blvd. Interceptor pipelines in place. Build Alternative 1 is located within paved public easements within city streets or OCSD easements. As such,the proposed improvements are expected to affect only areas that have been previously disturbed. The records search conducted for the proposed Project indicated that the proposed alignment falls within, or adjacent to,two previously disturbed archaeological sites: P-30- 001352 and P-30-001502. P-30-001352 was destroyed by the construction of 1-405, and the western Portion of P-30-001502 was destroyed by the construction of Seal Beach Boulevard and the Orange County Flood Control Channel. The remaining portions of P-30-001502 are on inaccessible property owned by the United States Navy and would not be impacted by the Project's construction activities. Furthermore,the field survey did not identify any newly discovered archaeological resources within the Project area. The documented disturbance and developed infrastructure through these sites or anywhere else within the proposed Project area do not preclude the potential for the presence of archaeological deposits. While the proposed Project is not expected to disturb these deposits,excavation in the proposed Project area could displace previously undisturbed soils containing archaeological materials, which will result in a significant impact. In this situation, the potential to adversely impact undiscovered cultural resources is unknown but potentially significant: however,implementation of CUL MM 1,CUL MM 7. and CUL MM 8 would reduce these potential impacts to less than significant(see Section 3.4.5 Mitigation Measures). Consultation with Native American Tribes has been initiated (See Appendix A), and those that have expressed an interest in this Proiect will continue to be apprised of Project activities and changes as the construction phase nears. For further details regarding consultation with the Gabrieleno Band of Mission Indians-Kizh Nation and the Juaneno Band of Mission Indians, refer to section 3.4 Cultural Resources, 3.4.4.3 Construction Impacts. Build Alternative 1 is anticipated to have a less than significant potential impact to archaeological resources as defined in Section 15064.5 of the California Code of Regulations. Based on the results of the records search,the Project would not intersect any previously recorded resources. Furthermore,the field survey resulted in no new discovery of archaeological resources. However, as the Project calls for open-cut trenching down to depths of up to 18 feet bgs alone portions of the Project alignment, the possibility remains that cultural resources that have vet to be identified or documented may be encountered.The results of the records searches and surveys are based on resources that were exposed on or near the surface; but this does not exclude the possibility of subsurface deposits at lower depths, particularly in areas comprising native or undisturbed soils. In this situation, the potential to adversely impact undiscovered cultural resources is unknown but potentially significant: however, implementation of CUL MM 1, CUL MM 7. and CUL MM 8 would reduce these potential impacts to less than significant (see Section 3.4.5). Rehabilitation of Western Regionol Sewers, Project 3-64 3-242 3.13—Tribal Cultural Resources Build Alternative 2 Build Alternative 2 would replace the entire Los Alamitos Sub-trunk pipeline with new, larger capacity pipe. This build alternative also would divert all flow from the Westside Relief Interceptor north of Orange Avenue to an enlarged Los Alamitos Sub-trunk via a new diversion structure. Build Alternative 2 would rehabilitate the entire length of the Western Relief Interceptor, as well as the Orange-Western Sub-trunk and the Seal Beach Blvd. Interceptor pipelines, in place using CIPP methods. Build Alternative 2 also would require manholes to be rehabilitated or replaced, contingent upon conditions and access point sizes.The alignment of the Los Alamitos Sub-trunk pipeline, currently 34,620 feet long, would be increased to accommodate flows from the Westside Relief Interceptor through a new diversion structure at Denni Street and Orange Avenue. In addition,the current Pipe diameters of the alignment. 18 inches to 30 inches, would be increased to diameters of 21 inches to 39 inches. The new pipeline would require trenching and open-cut construction to a depth up to 18 feet bgs along the entire Los Alamitos Sub-trunk street alignment. This would result in an additional 3,070 linear feet of open-cut trenching compared to Build Alternative 1. Build Alternative 2 is anticipated to have a less than significant potential impact to archaeological resources as defined in Section 15064.5 of the California Code of Regulations. Based on the results of the records search.the Project would not intersect any Previously recorded resources. Furthermore,the field survey resulted in no new discovery of archaeological resources.

In this situation, the potential to adversely impact undiscovered cultural resources is unknown but potentially significant: however,implementation of CUL MM 1, CUL MM 7. and CUL MM 8 would reduce these potential impacts to less than significant (see Section 3.4.5). 3.13.4.3 OnerationollmMets Operations under both Build Alternative 1 and Build Alternative 2 would consist of ongoing activities related to operation and maintenance of the Western Regional Sewer lines and the Westside Pump Station including completing routine maintenance,cleaning sewer lines and manholes; performing visual inspections utilizing closed-circuit television and camera inspection;and conducting flow-monitoring, as- needed repairs, and chemical dosing for odor and corrosion control. Operation of the Proposed Project would not involve excavation within previously undisturbed soils. The proposed Project would result in no operational impacts to archaeological resources as defined in Section 15064.5, and no mitigation is required. Rehabilitation of Western Regionol Sewers, Project 3-64 3-243 3.13—Tribal Cultural Resources 3.13.5 Mitigation Measures CUL MM 1: OCSD shall retain an archaeologist (Project Archaeologist) meeting the Secretary of the Interior's Standards for Professional Qualified Staff (PQS) to provide worker awareness training regarding archaeological resources to construction personnel prior to the start of construction.The training shall include,at minimum,the following: • The types of artifacts, features, or structures that could occur at the proposed Project site • The procedures that should be taken in the event of an archaeological discovery, including human remains • Laws protecting archaeological resources and burials • Penalties for destroying or removing archaeological resources, protected historical structures,or burials CUL MM 7: In the event of unanticioated archaeological. tribal, or paleontological resource discoveries during construction activities, the contractor shall stop work within 50 feet of the discovery until it can be evaluated by a qualified archaeologist meeting the Secretary of the Interiors Standards for Professional Qualified Staff (PQS) or a paleontologist meeting the professional standards enumerated in Cooper et al 2010. Construction activities may continue in other areas of the site. The qualified archaeologist or paleontologist shall evaluate the resources) encountered and recommend appropriate disposition of the resource(s) in consultation with the Orange County Sanitation District. CUL MM 8: Should any tribal entity identified on the Native American Heritage Commission contact list request on-site monitoring during construction of particular segments of the Project area out of concern for potential impacts to known or unanticipated tribal resources. OCSD shall provide a tribal approved Native American monitor/liajson'a. Sections of the Project area that may require such monitoring are contingent upon engineering design specifics which have vet to be finalized. 3.13.6 Level of Significance after Mitigation The proposed Project would have less than significant impacts to tribal cultural resources. Mitigation measures are necessary to reduce such impacts to less than significant levels. Therefore, implementation of CUL MM 1. CUL MM 7. and CUL MM 8 would render potential impacts on tribal Two such tribes have reauested the presence of an on-site monitor for the proposed Proiect in response to AB 52 consultations with OCSD(See Appendix Al. Rehabilitation of Western Regional sewers, Project 3-64 3-244 3.13—Tribal Cultural Resources cultural resources to the level of less than significant. In addition, the implementation of these mitigation measures would reduce impact to burials and human remains from potentially significant to less than significant with mitigation. Rehabilitation of Western Regionol sewers, Project 3-64 3-245 3.13—Tribal Cultural Resources This page intentionally left blank Rehabilitation of Western Regional sewers, Project 3-64 3-246 4.0-Cumulative Effects 4.0 Cumulative Effects Section 15355 of the California Environmental Quality Act(CEQA) Guidelines defines cumulative impacts as "two or more individual effects which, when considered together, are considerable or which compound or increase other environmental impacts." Section 15130 of the CEQA Guidelines provides guidance for analyzing significant cumulative impacts in an Environmental Impact Report (EIR). According to Section 15130,the discussion of cumulative impacts "...need not provide as great detail as is provided for the effects attributable to the project alone. The discussion should be guided by standards of practicality and reasonableness." The discussion should also focus only on significant effects resulting from the project's incremental effects and the effects of other projects. According to Section 15130(a)(1), "]a]n EIR should not discuss impacts which do not result in part from the project evaluated in the EIR." Cumulative impacts more result from the combined effect over time of other related past, present, and reasonably foreseeable future projects located in proximity to the project under review.Therefore, it is important for a cumulative impacts analysis to be viewed over time and in conjunction with other related past, present, and reasonably foreseeable future developments whose impacts might compound or interrelate with those of the project under review. 4.1 Cumulative Impact Analysis According to Section 15130(b) of the CEQA Guidelines, cumulative impact analysis may be conducted and presented by either of two methods: (1) a list of past, present, and probable projects producing related or cumulative impacts; or(2) a summary of projections contained in an adopted general plan or related planning document, or in a prior environmental document that has been adopted or certified, which described or evaluated regional or area-wide conditions contributing to the cumulative impact. The cumulative list approach has been utilized in the cumulative analysis presented in this chapter, as discussed below in Section 4.1.1. 4.1.1 Cumulative Project List Cumulative impacts for all environmental issue areas are based on a list of projects within the Project area that are in planning or design, are under construction, or have recently been completed. The cumulative projects list provided in Table 4.1-1 was developed by contacting the planning departments in the affected local jurisdictions and reviewing their websites, prior to beginning circulation of the Draft EIR in October 2016.The Project area includes the affected streets,easements,and OCSD property within the affected jurisdictions described in Chapter 2.0. Rehabilitation of Western Regional sewers, Project 3-64 4-1 4.0-Cumulative Effects Table 4.1-1: Cumulative Project List Cumulative Project Number Project:Status 1 1-405 Widening Project:Design Caltrans/OCTA are proposing to improve the San Diego Freeway(1-405) by adding one general purpose lane and a tolled express lane in each direction between SR-73 and 1-605.The project would include improvements on 1-405,including approximately 16 miles within the County of Orange,as well as portions of SR-22,SR-73,and 1-605.Final design and construction of the project are anticipated to occur Caltrans/OCTA between 2017 and 2022. 2 Katella Avenue/1-605 Interchange Project:Planning Caltrans/OCTA are proposing improvements to the Katella Interchange on 1-605. 3 SR-22 West County Connectors Project:Completed Caltrans/OCTA constructed SR-22/1-405 and 1.405/1-605 HOV connectors.The project also included improvements to the Valley View and Seal Beach interchanges,widening of the 1-405,and reconstruction of the 7"Street off-ramp. 4 OC Loop Project: Planning/Design/Construction OCTA is currently implementing projects to close approximately 20 miles of gaps in the multi-use network throughout Orange County. Once completed,the OC Loop will be a 66-mile Class I facility. OCTA 5 Katella Ave.BRT:OCTA has proposed the construction and operation of a bus rapid transit(BRT)line on Katella Avenue between Valley View Street on the east and Studebaker Road in Long Beach on the west. Within the Western Regional Sewers Project area,BRT stations are proposed at the intersections of Katella Avenue/Bloomfield and Katella Avenue/Los Alamitos Boulevard. 6 Expansion of Los Alamitos Medical Center:Design Expansion of the Los Alamitos Medical Center,located on the north side of Katella Avenue between Bloomfield and Cherry streets,is anticipated to be completed in 2025. 7 Los Alamitos Plaza Redevelopment:Planning Los Alamitos Plaza, located between Reagan Street and Los Alamitos City of Los Alamitos Boulevard on the north side of Katella Avenue was identified for redevelopment in Los Alamitos'2014 General Plan. 8 Los Alamitos Boulevard Bike and Pedestrian Improvements: Planning The planned improvement of Los Alamitos Boulevard would include vehicle,multi-modal,and pedestrian improvements. 9 Class 11 Bikeway/Oak Street: Planning The creation of a Class 11 bikeway is planned on Oak Street from Rehabilitation of Western Regionol Sewers, Project 3-64 4-2 4.0-Cumulative Effects Table 4.1-1: Cumulative Project List I Project:Status Sausalito Street to Katella Avenue. Buena Park N/A No project identified within Project area. Seal Beach N/A No project identified within Project area. La Palma N/A No project identified within Project area. 10 Barton Place Project:Design A Final EIR was certified in October 2015 by the City of Cypress for the Barton Place Project,a 33-acre development located on the north side of Katella Avenue at Enterprise Drive.The proposed development would include a senior residential community and commercial space in Cypress the location of the former Cypress Golf Club. 11 Forest Lawn New Mausoleum and Garden of Completion projects: Mausoleum construction is underway and anticipated to be completed in 2017.The Garden of Completion is anticipated to be completed by 2016 or 2017. TBD No projects identified within the Project area;however,development Anaheim of an apartment building located on a vacant lot at 3701 West Mungal Drive has been proposed. The discussion in the following sections evaluates the potential for the proposed Project to result in a significant adverse cumulative effect on the environmental resources discussed in Chapter 3.0. The analysis evaluates: (1) whether the combined impact of the proposed Project and other projects is significant, and if so (2) whether the project's incremental effect is cumulatively considerable. (CEQA Guidelines§ 15130.) 4.1.z Aesthetics The geographic area affected by cumulative projects for aesthetics is primarily restricted to the surrounding areas with direct views of the Project area. A significant adverse cumulative aesthetic impact would occur if the construction and operation of the proposed Project, when considered with the cumulative projects listed in Table 4.1-1, would result in permanent impacts that would degrade the existing visual character and quality of the Project area or day or nighttime views of the area. As described in Section 3.1,replacement of the Los Alamitos Sub-trunk within the Forest Lawn Cemetery would result in the presence of construction equipment and activities within the Forest Lawn Cemetery that would temporarily degrade the existing character and quality of the site and surroundings during interment ceremonies. During replacement of the Los Alamitos Sub-trunk within the Forest Lawn Rehabilitation of Western Regional Sewers, Project 3-64 4-3 4.0-Cumulative Effects Cemetery, the proposed Project would also require trimming and/or removal of mature trees that have been planted over or near the pipeline. Additionally, depending on final design,the replacement of the Westside Relief Interceptor pipeline within the City of Los Alamitos on Los Alamitos Boulevard and Katella Avenue may require removal of trees within the median. Following construction of the proposed Project,the Project area would be restored to its existing condition and not require any new lighting. The proposed Project may also require the construction of a new enclosure at the Westside Pump Station if an air scrubber is constructed.The Westside Pump Station would not be visible from any of the other cumulative projects and would not contribute to cumulative visual impacts. The new enclosure, if necessary,would be consistent with the existing visual character and quality. As discussed in Section 3.1, all proposed Project visual impacts were mitigated to less than significant with implementation of mitigation measures AES MM 1 through AES MM S. When the proposed Project is considered with the other cumulative projects listed in Table 4.1-1, it would not contribute to significant adverse cumulative effect. All other cumulative projects are within urbanized areas that will not greatly alter the aesthetics or introduce new sources of light and glare. The construction and operation of proposed Project in combination with the other cumulative projects listed in Table 4.1-1 would not create cumulatively considerable impacts relative to visual resources. 4.1.3 Air QualiTy The geographic area affected by cumulative projects for air quality includes the cumulative projects within the Project area and within the SCAB. A significant adverse cumulative air quality impact would occur if emissions from the construction and operation of the proposed Project, when considered with the emissions from construction and operation of the cumulative projects listed in Table 4.1-1, would degrade the air quality below acceptable levels. As described in Section 3.2, if the proposed Project requires the construction in a manner that would exceed 100 lbs./day of NO, then the project would result in significant air quality impacts. With implementation of AQ MM 1, project impacts would be less than significant. Construction of the cumulative projects listed in Table 4.1-1 could overlap with the construction of the proposed Project and could potentially contribute to a significant cumulative air quality impact. However, when considered with the cumulative projects listed in Table 4.1-1, it is not anticipated that the proposed Project would result in a significant contribution due to implementation of AQ MM 1, construction phasing, and adherence to SCAQMD Rules. Construction of the proposed Project would not result in cumulatively considerable air quality impacts. Operation of the proposed Project would not result in any increase in operational emissions. Operation of the proposed Project would not result in cumulatively considerable air quality impacts. Rehabilitation of Western Regionol Sewers, Project 3-64 4-4 4.0-Cumulative Effects 4.1.4 Bioloeieal Resources The geographic area affected by cumulative projects for biological resources includes the immediate surroundings of the proposed Project area. A significant adverse cumulative biological resource impact would occur if the construction and operation of the cumulative projects would affect biological resources protected by policies or ordinances. As described in Section 3.3, the Cities of Los Alamitos and Seal Beach are the only cities with tree protection ordinances. Replacement of the Westside Relief Interceptor pipeline within the City of Los Alamitos on Los Alamitos Boulevard and Katella Avenue may require removal of trees. With implementation of BIO MM 1,the proposed Project impacts would be less than significant.Construction of the cumulative projects listed in Table 4.1-1 within the City of Los Alamitos could contribute to a significant effect on biological resources protected by policy or ordinance. However, when considered with the cumulative projects listed in Table 4.1-1, it is not anticipated that the construction or operation of the proposed Project would result a significant contribution due to replacement of trees provided by BIO MM 1. Construction and operation of the proposed Project would not result in cumulatively considerable impacts to special status species or sensitive natural communities or conflict with any local policies or ordinances protecting biological resources. 4.1.5 Cultural Resources The geographic area affected by cumulative projects for cultural resources is the project construction disturbance area. A significant adverse cumulative cultural resource impact would occur if the construction and operation of the cumulative projects would cause a substantial adverse change in the significance of historical archaeological or paleontological resources or disturb human remains. As described in Section 3.4, excavation for open-cut construction for the Los Alamitos Sub-trunk and the Westside Relief Interceptor would require excavation in previously undisturbed soils that may contain archaeological sites or objects; paleontological resources; and, although unlikely, human remains both within and outside Forest Lawn Cemetery. The Project would have potential impacts to archaeological, historical, and paleontological resources, and human remains; however, with implementation of CUL MM 1 through CUL MM 8 the impacts would remain or be rendered less than significant. Construction and operation of the proposed Project, when considered with the cumulative projects listed in Table 4.1-1, are not anticipated to result in a significant contribution due to implementation of CUL MM 1 through CUL MM 8 and ECMs listed in Table 2.10-1 regarding procedures for inadvertent discovery listed in Chapter 2.0. Rehabilitation of Western Regionol sewers, Project 3-64 4-5 4.0-Cumulative Effects 4.1.6 Geology and Soils The geographic area affected by cumulative projects for geology and soils includes the immediate surroundings of the Project area. A significant adverse cumulative effect on geology and soils would result from projects that combine to create geologic hazards, including unstable geologic conditions,or substantially contribute to erosion. As described in Section 3.5,the proposed Project would result in less-than-significant impacts related to geology and soils. Environmental control measures (ECMs), described in Chapter 2.0 and listed in Table 2.10-1,would ensure that the potential for geological impacts resulting from the proposed Project would be less than significant. Construction of the cumulative projects listed in Table 4.1-1 would be subject to similar geologic hazards due to their location in seismically active southern California. However, all of the cumulative projects listed would be required to adhere to similar geotechnical design specifications and construction provisions in order to minimize and avoid significant geologic hazards.The construction and operation of the proposed Project, when considered with the cumulative projects listed in Table 4.1-1, would not result in a significant cumulative impact related to geology and soils. 4.1.E Greenhouse Gas Emissions The geographic area affected by cumulative projects for greenhouse gas (GHG) emissions includes the immediate surroundings of the Project area,the region, and the State of California. A significant adverse cumulative effect would result if the combined construction and operation of the cumulative projects would generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment or would conflict with an applicable plan or policy adopted to reduce GHG emissions. As described in Section 3.6, trends in GHGs indicate a 1.5-million-MtCO2e decrease from 2012 to 2013 and 7-percent decrease since peak levels in 2004. The proposed Project will have a less than significant impact on GHG emissions.The cumulative projects listed in Table 4.1-1 would not likely detract from the downward trend in GHG emissions during construction. Due to the nature of these projects (i.e., non- industrial),current construction standards for use of energy-efficient fixtures,operation of the proposed Project, when considered with the projects listed in Table 4.1-1, would not conflict with any plan or polity to reduce GHG emissions. It should be noted that construction of the proposed Project would result in a temporary increase in GHGs; however,the increase is anticipated to be minor and would not contribute to cumulative impacts. Operation of the proposed Project, when considered with the cumulative projects listed in Table 4.1-1, would not result in a significant cumulative impact related to GHGs. Rehabilitation of Western Regionol Sewers, Project 3-64 4-6 4.0-Cumulative Effects 4.1.8 Hazards and Hazardous Materials The geographic area affected by cumulative projects for hazards and hazardous materials includes the immediate surroundings of the proposed Project area. A significant adverse cumulative effect on hazards and hazardous materials would result from the additional exposure to people and the environment within the geographic area due to the presence of soil and groundwater contamination in the Project area. As described in Section 3.7, the proposed Project would result in potentially significant impacts associated with hazards and hazardous materials. With implementation of HAZ MM 1, impacts of the proposed Project would be less than significant. In addition,the proposed Project would be required to comply with all federal, state, and local regulations associated with construction near hazardous materials and the use, handling,transportation, and storage of hazardous materials. Significant hazards associated with the proposed Project include the potential to encounter contaminated soil and groundwater during excavation to replace portions of the Los Alamitos Sub-trunk and the Westside Relief Interceptor, their close proximity to surrounding schools, and the potential to create a hazard to the public or the environment due to the proximity to the Naval Weapons Station Seal Beach (site listed pursuant to Government Code Section 65962.5).Cumulative projects listed in Table 4.1-1 located within the immediate vicinity of the proposed Project could contribute to similar hazards or result in similar impacts related to hazardous materials; however, the cumulative projects would also be required to comply with federal, state, and local regulations that would minimize or avoid potentially significant impacts.The construction and operation of the proposed Project, when considered with the cumulative projects listed in Table 4.1-1, would not result in a significant cumulative impact related to hazards and hazardous materials. 4.1.9 Land Use and Planning The geographic area affected by cumulative projects for land use and planning includes the immediate surroundings of the proposed Project area. A significant adverse cumulative effect on land use and planning would result from projects that contribute to development that is inconsistent with applicable plans or are incompatible with existing or planned uses or planned addition of incompatible uses. As described in Section 3.8, Land Use and Planning, the proposed Project would result in significant impacts to land use and planning associated with construction noise and nighttime construction. Applicable land use plans or regulations of agencies with jurisdiction over the Project area can be found in Section 3.8.1. Consistency analysis for the plans is included in Table 3.8-2. With implementation of measures NOI MM 1, NO1 MM 2, AQ MM 1, and AES MM 5, in addition to the requirement that a variance must be obtained prior to any nighttime work, impacts would be less than significant. Construction of the cumulative projects listed in Table 4.1-1 that occur within the proposed Project area could contribute to significant effects related to construction noise or nighttime construction. It is Rehabilitation of Western Regional Sewers, Project 3-64 4-7 4.0-Cumulative Effects assumed that the cumulative projects listed in Table 4.1-1 would be required to comply with the respective city's general plan, zoning ordinance, and any applicable community plans. Projects that are not consistent with their city's general plan land use designation, zoning, or community plan designations would require adoption of a general plan amendment, zone change, and/or community plan amendment. Projects that require a general plan amendment and/or community plan amendment are required to demonstrate conformance with pertinent goals, policies, and recommendations. The construction and operation of the proposed Project when considered with the cumulative projects listed in Table 4.1-1 would not result in a significant cumulative impact related to Land Use and Planning. 4.1.10 Noise The geographic area affected by cumulative projects for noise includes sensitive receptors within the 90- A-Weighted decibel (dBA)contours shown in Figure 3.9-2 through Figure 3.9-13. A significant adverse cumulative effect on noise would result when projects generate noise levels that, when combined, would be considered a substantial temporary increase in noise levels above the ambient conditions. As discussed in Section 3.9, temporary increases in ambient noise levels at or above 90 dBA would mostly be experienced in the replacement areas where open-trench activities would occur along portions of the Los Alamitos Sub-trunk and the Westside Relief Interceptor. Because the ultimate pipe location and construction method would not be determined until final design, Figure 3.9-2 through Figure 3.9-13 depict the worst-case 90-dBA noise contour for the proposed Project. This contour is based on open-cut construction with the construction generating noise sources being located at the curb on both sides of the Project area. Construction noise impacts on receptors within the 90-dBA contour would be significant, and mitigation measures(N01 MM 1 and N01 MM 2)would be required to reduce impacts; however, impacts would remain significant and unavoidable after mitigation. When considered with the cumulative projects listed in Table 4.1-1, the cumulative projects located nearest the proposed Project area would involve construction that may overlap with construction of the proposed Project and result in cumulative noise impacts during construction. Although all cumulative projects would be required to adhere to the respective cities' noise ordinances and impacts would be mitigated on a project-by-project basis, the potential exists for overlapping construction noise to combine to exceed these standards. The proposed Project would result in potentially significant cumulative noise impacts. Mitigation measures would be implemented to reduce potential impacts; however, during construction impacts to sensitive receptors within the 90-dBA contour would remain significant.When the construction of the proposed Project is considered in combination with cumulative projects listed in Table 4.1-1, impacts are cumulatively considerable and remain significant and unavoidable. Noise from operation of the proposed Project would be the same as existing conditions and, when considered with the cumulative projects listed in Table 4.1-1, would not result in a cumulatively considerable impact related to noise. Rehabilitation of Western Regionol sewers, Project 3-64 4-8 4.0-Cumulative Effects 4.1.11 Public Services The geographic area affected by cumulative projects for public services includes the immediate surroundings of the Project area. A significant adverse cumulative effect on public services would result from projects that would substantially affect service ratios, response times, or other performance objectives for any of the public services. As described in Section 3.10, the proposed Project would result in less-than-significant impacts related to public services. Construction of the proposed Project could result in temporary traffic congestion associated with staging and construction of the proposed Project within public street rights-of-way. Construction of the proposed Project could also result in disruption or delay of fire and police protection, potential delays for school buses or other vehicles transporting students to and from schools, and temporary relocation/closure of bus stops. Environmental control measures (ECMs) described in Chapter 2.0 and listed in Table 2.10-1 would ensure that the potential impacts resulting from the proposed Project would be less than significant. Transportation control plans (TCPs) would be submitted to the affected jurisdiction for approval. Construction of the cumulative projects listed in Table 4.1-1 would be subject to similar requirements to ensure that project effects on service ratios, response times,or other performance objectives affected public services would be minimized and would avoid significant impacts on public services. The construction and operation of the proposed Project when considered with the cumulative projects listed in Table 4.1-1 would not result in a significant cumulative impact related to public services. 4.1.12 Recreation The geographic area affected by cumulative projects for recreation includes public parks in the immediate surroundings of the Project area. A significant adverse cumulative effect on recreation would result from any closure of parks. As described in Section 3.11, the proposed Project would result in less-than-significant impacts related to recreation. Construction of the proposed Project could result in temporary parking restrictions within the Project area. Impacts from the proposed Project on park access and parking would be temporary, and disruptions would be short in duration (days to weeks). Parks would remain open.The construction and operation of the proposed Project when considered with the cumulative projects listed in Table 4.1-1 would not result in a cumulatively considerable impact related to recreation. 4.1.13 Traffic and Circulation The geographic area affected by cumulative projects for traffic and circulation includes roadways and intersections within immediate surroundings of the Project area. Rehabilitation of Western Regionol sewers, Project 3-64 4-9 4.0-Cumulative Effects A significant adverse cumulative effect on traffic and circulation would result from trip-generating projects that impact the same roadways. As described in Section 3.12, the proposed Project would not result in significant impacts associated with transportation and traffic. Environmental control measures (ECMs) described in Chapter 2.0 and listed in Table 2.10-1 would be implemented. All construction within existing roadways would be temporary, and the roadways would be restored to their existing conditions after construction is complete. In addition, OCSD would contractually require that the traffic control plans (TCPs) specifically address construction traffic and road closures within the public rights-of-way of the Cities of Anaheim, Buena Park, Cypress, La Palma, Los Alamitos, and Seal Beach and the County of Orange. The traffic control plans would specify provisions for construction times and for allowance of bicyclists, pedestrians, and bus access throughout construction. The traffic control plans would also specify provisions to ensure emergency vehicle passage at all times, include signage and flagmen when necessary, and would be approved by each corresponding city in advance of construction. Temporary relocation of bus stops or closure of bike lanes would be coordinated with Orange County Transportation Authority (OCTA) service planning staff and local jurisdictions as required. During final design,Orange County Sanitation District(OCSD)would obtain an encroachment permit, as required,for all work that could affect freeway operations or encroach within state highway right-of-way. OCSD would contractually prohibit concurrent construction for the Westside Relief Interceptor and the Los Alamitos Sub-trunk on Katella Avenue. Once constructed, the proposed Project would not result in any increase in traffic, since existing staff would maintain the proposed pipelines. The cumulative projects listed in Table 4.1-1 have the potential to substantially increase traffic on surrounding roadways due to an increase in residential and commercial uses. Although the cumulative impact from these projects may be significant, the proposed Projects traffic impacts under either build alternative would be temporary and, due to the measures outlined above,would not be cumulatively considerable. 4.1.14 Tribal Cultural Resources The geographic area affected by cumulative projects for tribal cultural resources is the project construction disturbance area. A significant adverse cumulative tribal cultural resource impact would occur if there were a substantial adverse change in the significance of a tribal cultural resource. A tribal cultural resource is defined in Public Resources Code Section 21074 as either a site, feature, place, cultural landscape that is geographically defined in terms of the size and scope of the landscape, sacred Place, or object with cultural value to a California Native American tribe. As described in Section 3.4. open-cut trenching for the Los Alamitos Sub-trunk and the Westside Relief Interceptor would require excavation in previously undisturbed soils that may contain tribal cultural sites or obiects and, although unlikely, human remains. The Project could have potential impacts to tribal cultural resources and human remains; however, with implementation of CUL MM 1, CUL MM 7, and CUL MM 8 the impacts would remain or be rendered less than significant. Construction and Rehabilitation of Western Regional Sewers, Project 3-64 4-10 4.0-Cumulative Effects operation of the proposed Project, when considered with the cumulative projects listed in Table 4.1-1, are not anticipated to result in a significant contribution due to implementation of CUL MM 1. CUL MM 7. and CUL MM 8 and ECMs listed in Table 2.10-1 regarding procedures for inadvertent discovery listed in Chapter 2.0. Rehabilitation of Western Regionol sewers, Project 3-64 4-11 4.0-Cumulative Effects This page intentionally left blank Rehabilitation of Western Regional sewers, Project 3-64 4-12 5.0-Other CEQA Considerations 5.0 Other CEQA Considerations 5.1 Significant and Unavoidable Environmental Impacts As described in Chapter 3.0, Environmental Analysis, the proposed Project would result in significant impacts related to Aesthetics (3.1),Air Quality(3.2), Biological Resources (3.3), Cultural Resources (4.4), Hazards and Hazardous Materials (3.7), Land Use/Planning (3.8), and Noise (3.9). All of the significant impacts would be reduced to below a level of significance through implementation of mitigation measures, as described in each section,with the exception of impacts to temporary increases in ambient noise levels during construction of the proposed Project(Impact NOI-4),which would remain significant and unavoidable after mitigation. As a result, Impact NOI-4 would be the only significant and unavoidable environmental impacts associated with the proposed Project. 5.2 Growth Inducement The CEQA Guidelines(Section 15126.2(d)) require that an EIR evaluate the growth-inducing impacts of a proposed project.Section 15126.2(d)calls for the EIR to: Discuss the way in which a proposed project could foster economic or population growth, or the construction of additional housing, either directly or indirectly, in the surrounding environment. Included in this are projects which would remove obstacles to population growth (a major expansion of a reclaimed water treatment plant might, for example, allow for more construction in service areas). Increases in the population may tax existing community service facilities, requiring construction of new facilities that could cause significant environmental effects. Also discuss the characteristic of some projects which may encourage and facilitate other activities that could significantly affect the environment, either individually or cumulatively. It must not he assumed that growth in any area is necessarily beneficial, detrimental, or of little significance to the environment. Construction of the proposed Project would continue for approximately four years, although it is not anticipated to create employment opportunities beyond the levels normally available to construction workers in the area. While additional workers would be required during construction of the proposed Project, it is anticipated that most of these workers would commute to the Project area from surrounding communities. In addition, once constructed, the proposed Project components would not require additional employees to maintain them. Therefore, the proposed Project would not have direct impacts on growth. As discussed in Section 4.13 of the initial study (Appendix A), rehabilitation and/or replacement of the Western Regional Sewers and improvements of the Westside Pump Station would not directly or indirectly induce substantial population growth in the area because the proposed Project involves Rehabilitation of Western Regional Sewers, Project 3-64 5-1 5.0-Other CEC A Considerations rehabilitation and/or replacement of the Western Regional Sewers and new construction to replace a wet well at an existing pump station; these components have exceeded their functional life. Capacity- deficient segments, as identified in Section 2.3, Purpose and Objectives, would be increased to accommodate 2040 wet weather peak flows (10-Year Storm); however, the proposed rehabilitation and/or replacement segments would not increase the capacity of the system, as the pipes would be replaced in-kind with no increase in pipe diameter and would not directly or indirectly induce substantial growth. 5.3 Energy Conservation The guidance on energy conservation in CEOA Guidelines Appendix F is based on the statutory requirement that the mitigation measures in an EIR include "measures to reduce the wasteful, inefficient, and unnecessary consumption of energy" (Public Resources Code Section 21100(b)(3)). Consistent with this mandate, CEOA Guidelines Appendix F lists possible energy impacts and potential conservation measures that should be considered in an EIR when they are"applicable or relevant to the project" and the impacts are "potentially significant" Appendix F does not mandate the analysis of particular energy-related impacts or include specific significance criteria by which to measure a project's energy impacts. For the purposes of this analysis, consideration is given to whether the project would result in the wasteful, inefficient,or unnecessary consumption of energy. 5.3•1 Construction Energy Impacts Construction of the proposed Project would require the use of electricity and diesel fuel. 5.3•1.1 Electricity Construction of the proposed Project would utilize existing electrical service, when available on-site (e.g., during construction of the improvements at the Westside Pump Station). Electrical demand during construction would be minimal and required only for operation of power hand tools, lighting, and other minor equipment needed for rehabilitation and/or replacement of the Western Regional Sewers and improvements of the Westside Pump Station. Electrical demand during construction would primarily be provided by generators in the field. Total energy consumption would be temporary and less than 100 kilowatts(kWh) per day.This is considered de minimis compared to 56 million kWh per day of electricity consumed in Orange County in 2014. Construction of the proposed Project would not use large amounts of electricity and would not use it in a wasteful manner(e.g., construction equipment not in use would be turned off), and impacts associated with use of electricity during construction would be less than significant. 53•1.2 Diesel Fuel Large construction equipment typically burns 4 to 10 gallons of diesel fuel an hour. Assuming all equipment consumed 30 gallons of diesel per hour and operated 8 hours per day, maximum daily diesel consumption would range from 1,040 gallons per day (construction of Westside Pump Station) to Rehabilitation of Western Regional Sewers, Project 3-64 5-2 5.0-Other CEQA Considerations 2,800 gallons per day(construction of the Los Alamitos Sub-trunk under either build alternative). Use of fuel during construction would be temporary.Construction of the proposed project would use only what is necessary and would not use large amounts of diesel fuel in a wasteful manner (e.g., construction equipment not in use would be turned off). Impacts associated with use of fuel for energy during construction would be less than significant. 5.3.2 Operational Energy Impacts Operational energy use would consist only of maintenance trips to the field and potential operation of an air scrubber at the Westside Pump Station in addition to the existing energy usage at the pump station. Operational energy use would be minimal and not result in the wasteful, inefficient, or unnecessary consumption of energy during operation.

The DEIR should LAusD evaluate the impact of the Project on the access in and out of these at". Due to the construction of 1 the Project,access to the sites well be Impeded.Delays to parent drop-off and school bus drop-off will impact student learning.The District is funded by the State based upon the students Average Daily Attendance.Student tardiness due to the Project will have a negative financial impact to the District. The DEIR does not adequately address the impact to Public Services. In addition to ingress to LAU60 Inform motonsis of construction delays,the Traffic Control Plan should specify provisions to ensure 2 school bus passage at all times and include signage and Bagmen to maintain school bus passage within and through the construction area. The District's school buses run on a very tight schedule board Irearaeon: Jos,Hoke •Dowd Boyer •Me an Cutuh •Diana D.Hill •Xaren Rueceb Rehabilitation of Western Regional Sewers, Project 3-64 8-21 8.0-Comment Letters and Response to Comments Orange County Sanitation District Page 2 Re: Draft Environmental Impact Report—Rehabilitation of Western Regional Sewers Project 3-64 November 29,2016 and service all of the Los Alamitos Unified School District schools in Seal Beach, the unincorporated -Aui community of Rossmoor and the City of Los Alamitos. As such, the Buses utilize Los Alamitos 2 Boulevard/Seal Beach Boulevard. The Auxiliary District Once facility utilizes Briggeman Drive as the main access route to Los Alamitos Boulevard. This facility services all of our schools and operates school buses, food services, maintenance and grounds. The peak hours of operation at this facility are from 6:00 AM through 4:30 PM, The DEIR tloes not adequately address Project noise and the impact to student learning. Mitigation measure NOI MMi specifically calls out nighttime and weekend construction however the Los LAUSD 3 Alamitos High School conducts SAT and Act testing on weekends. The DEIR should require that the OCSD obtain testing schedules from each of the aforementioned schools and temporarily suspend construction activities during those times. The DEIR does not adequately address pedestrian safety. The requirements for neither the Materials Management Plan nor the Traffic Control Plan adequately address safety concerns due to LAUSD heavy pedestrian and vehicular traffic at the start and stop times of the surrounding schools. Nor 4 does it address the safety hazards for school aged children due to open trenches around the school sites and along the pedestrian corridors. The DEIR should require that the OCSD obtain the school schedules and plan their construction start times around the school start and stop times to minimize the impact. Note that the Los Alamitos High School frequently has activities that extend into the night I time hours Monday through Saturday. LAUsq Once again,the District thanks the OCSD for the opportunity to comment on the DEIR. The District 5 I formally requests to be included on the distribution list for the Revised DEIR and Final EIR,as well as all other OCSD projects. We trust that our participation in the environmental review of the Project will ensure that the Project's impacts on the environment, as well as the District schools, are adequately addressed.You may contact me at(562)799A700 ext. 80449 to discuss these comments further.

During final design detailed utility mapping would be conducted to identify utility constraints. Pipe bursting would be in the same location and therefore there would be adequate space. Response FLMPA 2 The upper reach of cemetery reauires an increase in the pipe diameter by more than 66%: as such pipe bursting is not a feasible alternative, because this method cannot be used to enlarge pipes to that size. Therefore, microtunneling or open-cut trenching are the only viable options in this segment: however, open-cut trenching would be far faster than microtunneling. Construction methods are limited by the elevations of segments that the replaced pipe would connect to. OCSD will further analyze options during final design to determine the feasibility of constructing all open-cut segments within the cemetery during nighttime hours(see AES MM 1a). Response FLMPA 3 As stated on pages 3-9 and 3-10 of the EIR. "The business operations and the scenic areas within the Forest Lawn Memorial Park cemetery are more sensitive to the presence of construction equipment and materials than the typical businesses or the residential areas adjacent to city streets. The Project area within Forest Lawn would be visible from many areas of the Forest Lawn property. The replacement of the Los Alamitos Sub-trunk within the cemetery would be completed in approximately two to three months. Because of the temporary nature of the proposed construction activities within Forest Lawn,visual impacts would not be significant" This is related to the typical business operations associated with Forest Lawn Memorials with the exception of scheduled interment ceremonies. Response FLMPA 4 The EIR points out visual impacts during construction would temporarily impact interment ceremonies, significantly. Rehabilitation of Western Regional Sewers, Project 3-64 8-32 8.0-Comment Letters and Response to Comments "However, the visual impacts of the construction equipment and activities would degrade the existing tranouil character and ouality of the site and the surroundings during interment ceremonies due to the hypersensitivity of the participants. (Page 3-101 This would be a emoorary significant impact requiring implementation of mitigation measures AES MM 1. AE MM la. CUL MM 3. and CUL MM 5 to reduce the impact to less than significant." (See page 3- 12. This temporary construction impact would be significant if mitigation measures were not adopted. The EIR describes three mitigation measures that would be put in place to reduce impacts to less than significant. AES MM 1: OCSD will obtain interment schedules from the Forest Lawn Cemetery and temporarily suspend construction activities for fepk.�.�„r--' --` the Los Alamitos Sub-trunk within the Forest Lawn Cemetery during interment ceremonies to minimize construction disturbances to Forest Lawn operations. CUL MM 3: Final design of the Los Alamitos Sub-trunk within Forest Lawn shall avoid disturbance of historic buildings, structures, or objects on the Forest Lawn property that are outside the OCSD easements. These include the Ascension Mausoleum: the Church of Our Fathers: the Main Mortuary Building: the Park's maintenance facilities building: and the park entrance,memorial tablets,grave markers,stones,statues,and ornaments. CUL MM 5: For the portion of the Los Alamitos Sub-trunk within Forest Lawn Cemetery, the contractor shall avoid disturbance of interment ceremonies and gravesites through the use of protective barriers,visual aids (i.e., signs, flagging, etc.) and defined exclusion areas on plans to Provide mutually acceptable distance between construction areas and interments, as determined in consultation with Forest Lawn Cemetery management. Visual aids shall distinguish ornamental or structural elements from locations of known gravesites. Also. OCSD will provide a liaison during construction of the Los Alamitos Sub-trunk within the Forest Lawn Cemetery (page 3-771 to avoid disturbance to existing gravesites and determine the appropriate course of action in the event there are anticipated impacts or unavoidable impacts to gravesites in order to avoid further impacts. We have added "and CUL MM 3. and CUL MM 5"to Section 3.1.6 Level of Significance after Mitigation. The section now reads "Impacts to visual resources and aesthetics would be reduced to less than significant with the implementation of mitigation measures AES MM 1 through AES MM 5 and CUL MM 3.and CUL MM 5." Response FLMPA 5 Rehabilitation of Western Regional Sewers, Project 3-64 8-33 8.0-Comment Letters and Response to Comments In order to reduce significant aesthetic impacts to Forest Lawn associated with construction eauioment and activities. OCSD will also provide visual screening of Construction Eouipment and Activities during work at in and adjacent to Forest Lawn. The following language has been added to Section 3.1.5 Mitigation Measures,AES MM 1: Visual screening will also be installed where work will occur adjacent to and within Forest Lawn in order to reduce temporary impacts associated with construction eauioment and activities. Construction activities associated with the Western Regional Sewers would occur during the day when feasible in order to avoid impacting adjacent residential areas. As described in Section 2.5 and 3.1.4.3, construction on all major streets would occur during hours approved by the corresponding iurisdiction. Night work will be required in some areas along major roads in order to reduce traffic and noise impacts. To minimize aesthetic (and noise) impacts to Forest Lawn associated with construction, the following mitigation measure has been added to Section 3.1.5: ES MM la: More djsruotjve construction requiring segments of open-cut trenching within th Forest Lawn property will be conducted at night.where feasible,to minimize signfficant jmga to vjsitors Response FLMPA 6 Removal of trees will only occur if necessary. If more than '%of the tree root system is impacted during construction, the tree will likely not survive and would need to be removed. Use of trenchless technologies is not a guarantee that trees would be protected. To mitigate impacts to trees removed and trimmed during construction mitigation proposed in the EIR included: AES MM2: Based on final design and prior to removal or trimming of any tree. OCSD will identify all trees that require removal or trimming. For trees located within the existing easement, OCSD will work with property owners regarding in-kind replacement landscaping for the corresponding municipality or private owner. The following language has been added to the end of AES MM 2: The OCSD liaison to Forest Lawn will work with cemetery representatives during tree trimming removal and replacement within the cemetery property. Coordination with Forest Lawn wil include identifying trees to be removed and trimmed prior to cutting, discussing-trees-of concern and protection options. and determining species, size and planting locations for enlacement specimens. The size of replacement trees will be comparable to trees remove where possible and where site conditions allow. Rehabilitation of Western Regional Sewers, Project 3-64 8-34 8.0-Comment Letters and Response to Comments Response FLMPA 7 Alternative alignments around and through Forest Lawn Memorial Park were considered and found to be infeasible due to differences in surrounding elevations and the impacts of connecting pipelines on new alignments outside of existing public rights-of-way and OCSD sewer easements. Response FLMPA 8 Trenchless pipeline replacement, using techniques such as microtunneling, may be a feasible option in some segments through the cemetery. However,open-cut trenching would be far faster than microtunneline so there are tradeoffs to consider. Construction methods are limited by the elevations of segments that the replaced pipe would connect to,and trenchless construction techniques such as Pipe-bursting may not be feasible due to soil or groundwater conditions. In consultation with Forest Lawn representatives.OCSD would consider trenchless pipeline replacement methods in appropriate locations within the cemetery during final design. Response FLMPA 9 OCSD acknowledges that the entire cemetery is a historic resource/district with many features that contribute to its significance. The buildings, structures, and objects within the cemetery would be avoided and OCSD would Provide a Project liaison on site during construction through the cemetery to insure that those features and any internments are avoided (see Section 3.4.5, Appendix C-2, Table 1, and Figures 6 and 7 of the EIR). As discussed in the above response to FLMPA 8.trenchless construction will be used to the extent feasible. Open trench areas would be within the ROW of Guardian Drive. Following construction of the proposed Project, the Project area would be restored to its existing condition and repaired after sewer upgrades to minimize the disturbance and any temporary visual effects caused by the sewer line replacement. Response FLMPA 10 There are no historic buildings, structures, or objects within the OCSD easement that would be affected by the sewer line replacement. The alignment of the Project has been designed to avoid these types of properties and is almost entirely situated alone or immediately adjacent to the existing road pavement (see Appendix C-1, Figures 6 and 7 of the EIR). Since the alignment avoids these historic structures,there would be no modifications or alterations to any statues,gravestones,walkways, landscapes,gardens,or other elements. Response FLMPA 11 According to the IS, the project would result in a Less than Significant Impact on a geologic unit or soil that is unstable. The Proposed improvements would be designed and constructed in conformance with the recommendations of a project specific Reotechnical report, in accordance with the current Uniform Rehabilitation of Western Regional Sewers, Project 3-64 8-35 8.0-Comment Letters and Response to Comments Building Code and California Building Code seismic engineering standards and other applicable building codes. Backfill would be placed to meet standard engineering design requirements and local grading practices. Potential impacts due to an unstable geologic unit or soil, resulting in lateral spreading, subsidence, or collapse will be avoided. Impacts on the project associated with on- or off-site lateral spreading, subsidence, or collapse would be less than significant. No further review in the EIR was determined to be necessary. Response FLMPA 12 As a part of General Construction Measures section of Table 2.10-1 Environmental Control Measures: "If groundwater dewaterine is necessary, construction site dewaterine water will be tested. Where suitable, water will be discharged to the OCSD sewer. Where water exceeds OCSD thresholds for discharge to sewers, the contractor will either treat to meet OCSD sewer discharge reauirements or containerize and dispose of dewaterine at a licensed facility." This section also specifies: "OCSD will require construction contractors to prepare and implement stormwater pollution and prevention plans(SWPPPs)that specify best management practices(BMPs)to be implemented during project construction to prevent pollutants from entering stormwater and to control erosion and sedimentation. The SWPPPs will be prepared and submitted to the Regional Water Quality Control Board(RWQCB)for review and approval prior to the start of construction." Response FLMPA 13 While there is no specific hydrology/water auality analysis in the EIR, as none were deemed necessary by the IS, concerns related to encountering perched groundwater are addressed in the Environmental Control Measure for General Construction Activities as outlined in the above response to Comment 11. Response FLMPA 14 The Forest lawn Cemetery was included in the noise analysis. Reference to the cemetery as a noise sensitive receptor was inadvertently omitted in Section 3.9.2.1 under existing noise conditions. This section has been updated to include the cemetery in the list of receptors within the Proiect area. Ambient noise levels at this receptor were estimated to be approximately 48 dBA and estimated construction noise levels would be 91 dBA resulting in a temporary construction noise impact above 90 dBA.Additional information is provided in section 3.9.4. Response FLMPA 15 Significant and unavoidable impacts result from substantial temporary increases in noise over existing conditions regardless of the construction method (open trench or trenchless). Adding noise levels from construction of the proposed Project to ambient conditions would generate temporary increases in ambient noise levels at or above 90 dBA, mostly in the pipe replacement areas where open-trench construction would occur along portions of the Los Alamitos Sub-trunk. The ultimate pipe location and Rehabilitation of Western Regionol Sewers, Project 3-64 8-36 8.0-Comment Letters and Response to Comments construction method would not be determined until final design as discussed in response to Comment 8. Also, see response to FLMPA 5 regarding consideration of nighttime construction in the cemetery under certain conditions. Response FLMPA 16 See response to FLMPA 5,8.and 14. Response FLMPA 17 Impacts to traffic within the cemetery were considered in the traffic analysis. Traffic impacts to the access roads to the cemetery were directly addressed by the requirement for TCPs. As a part of the Traffic and Circulation section of Table 2.10-1 Environmental Control Measures: "OCSD will require its construction contractors to prepare and implement traffic control plans (TCPs) that specifically address construction traffic and road closures within the Public rights-of-way of the Cities of Anaheim. Buena Park, Cypress, La Palma, Los Alamitos. and Seal Beach and within the County of Orange. The TCPs will specify permitted construction hours and will require that vehicular access be maintained in the Project area throughout construction of the proposed Project." The cemetery roadways do not convey through traffic and traffic within the cemetery roads uses continuous loop roads. It is anticipated that construction work in the cemetery would have less of an impact than on the surrounding roadways.As a specific mitigation measure for the cemetery: AES MM 1: OCSD will obtain interment schedules from the Forest Lawn Cemetery and temporarily suspend construction activities for replacement of the Los Alamitos Sub-trunk within the Forest Lawn Cemetery during interment ceremonies to minimize construction disturbances to Forest Lawn operations. Vsual screen ne w II also he "nstalled where work will occur within and adjacent to Forest Lawn in order to reduce tempgrary impacts to visitors associated with construction eauipmen[and activities Response FLMPA 18 As outlined in the previous response, impacts to traffic within the cemetery roadways were considered in the overall analysis. In regards to the request for trenchless technology to be utilized within the cemetery grounds,this would occur as described in response FLMPA 88. As discussed in response to FLMPA 5. OCSD will further analyze options during final design to determine the feasibility of constructing open-cut segments within the cemetery during nighttime hours. Response FLMPA 19 The upper reach of cemetery reauires an increase in the pipe diameter by more than 66%: as such pipe bursting is not a feasible alternative, because it can't be used to enlarge pipes to that size. Therefore, microtunneling or open-cut are viable options in this segment: however, open-cut would be far faster Rehabilitation of Western Regional Sewers, Project 3-64 8-37 8.0-Comment Letters and Response to Comments than microtunneling. Construction methods are limited by the elevations of segments that the replaced pipe would connect to. Response FLMPA 20 As described in the Section 2 of the Draft EIR, pipe bursting or in-line expansion is a trenchless method by which the existing Pipe is forced outward and opened by a bursting device(Figure 2.5 31.The bursting device, which has an expansion head that pushes the existing pipe radially outward until the pipe breaks, is pulled through the existing pipe by a cable rod and winch.As the bursting device breaks up the existing pipe,the new,typically larger pipe is pulled behind the bursting device and replaces the existing oioe. Pipe bursting and other trenchless methods would still require the Placement of equipment on site and some surface excavation at entrance and exit points. Response FLMPA 21 The upper, northern reach of the cemetery requires an increase in the pipe diameter by more than 66%.%. As such pipe bursting is not a feasible alternative, because it can't be used to enlarge pipes to that size. Therefore, microtunneline or open-cut are viable options in this segment: however, open-cut would be far faster than microtunneline so there would be tradeoffs to consider. Construction methods are limited by the elevations of segments that the replaced pipe would connect to. Cost benefit analysis of open trench construction versus Pipe bursting methods within the cemetery is not reauired for an EIR.

However, if shrub and tree removal must occur during the nesting season, a qualified wildlife biologist (as determined by California Department of Fish and Wildlife) shall conduct preconstruction surveys for nesting birds within suitable nesting habitat in the proposed Project area including a 300-foot buffer around the construction limits. The nesting bird surveys shall be conducted one week before initiation of construction activities within those habitats. If no active nests are detected during surveys, construction may proceed. If active nests are detected,then a no-disturbance buffer shall be established around nests identified during preconstruction surveys. The extent of the no-disturbance buffer shall be 50 feet for non-raptors and 300 feet for raptors. [These buffer distances may be altered by a qualified biologist depending on the level of noise or construction disturbance, line of sight between the nest and the disturbance, ambient levels of noise and other disturbances, and other topographic or artificial barriers. These buffers shall be maintained until after the breeding season has ended or until the biologist determines that the young have fledged. Within this buffer, all nonessential construction 1s The contractor will be encouraged to reduce NOx emissions by substituting equipment with Tier 4 engines that adhere to emissions standards listed in 40 CFR 1039.101 for all types of off-road equipment to which USEPA regulations apply.

The NCP will specifically address noise control near sensitive receptors and for construction for which a variance has been obtained from the appropriate jurisdiction (e.g., weekend and nighttime construction). The NCP will identify the location of noise-sensitive receptors and list the types of noise control measures proposed (e.g., sound blankets and temporary noise barriers providing 5 dBA to 23 dBA of noise reduction) and any conditions specified in the variance. Once approved by OCSD,the contractor will be required to implement the plan. To ensure compliance with the NCP, the contractor will be required to monitor all construction noise for activities potentially affecting sensitive receptors in areas approved by variance, as well as all schools, hospitals, convalescent homes, churches, and other noise-sensitive areas within 1,000 feet of the construction activities. If construction activities take place during weekend and nighttime hours near sensitive receptors that have activities occurring on site during these times,coordination will be conducted with the site owners/managers to ensure adequate measures are taken to reduce or avoid noise impacts.

Interceptor.Collectively,these sewer lines are identified as the Western Regional Sewers.These sewer lines convey sewage flows from the City of Seal Beach,the community of Rossmoor in unincorporated Orange County,the City of Los Alamitos,the City of Cypress,the City of La Palma,and other areas in the vicinity to the Westside Pump Station in Rossmoor.The Orange-Western Sub-trunk conveys flows from the Cities of Cypress, Buena Park,and Anaheim to the Miller Holder Trunk and the Knott Interceptor. The Orange-Western Sub-trunk is not tributary to the Westside Pump Station.Sewage flows from all Project components ultimately are directed to OCSD Treatment Plant No.2located at 22212 Brookhurst Street in Huntington Beach. Los Alamitos Sub-trunk The Los Alamitos Sub-trunk, constructed in 1959, is 34,620 feet long and has 90 manholes.The pipe diameter ranges in size from 18 to 30 inches.The Los Alamitos Sub-trunk is within the following cities: La Palma (La Palma Avenue and Denni Street),Cypress (Denni Street,Guardian Drive,Orange Avenue, Bloomfield Avenue,and Bloomfield Street), Los Alamitos(Bloomfield Street,West Cerritos Avenue, Chestnut Street,Sausalito Street,Oak Street, Katella Avenue,and Los Alamitos Boulevard),Seal Beach (Seal Beach Boulevard and Old Ranch Parkway),and the community of Rossmoor. Westside Relief Interceptor The Westside Relief Interceptor was constructed in 1975 and 1976.This line is approximately 32,100 feet long with 81 manholes. Pipe size ranges from 15 to 39 inches in diameter.The Westside Relief Interceptor is within the following cities: La Palma(Crescent Avenue and Moody Street), Cypress (Moody Street,Orange Avenue,and Denni Street), Los Alamitos(Denni Street, Katella Avenue,and Los Alamitos Boulevard),and Seal Beach (Seal Beach Boulevard and Old Ranch Parkway).The Los Alamitos Sub-trunk and Westside Relief Interceptor meet at the intersection of Orange Avenue and Denni Street at Diversion Structure No.65. Diversion Structure No.65 is configured to divert southerly flow from the Los Alamitos Sub-trunk to the west, rather than allowing it to continue southward along with flow from the Westside Relief Interceptor.The Los Alamitos Sub-trunk can flow into the Westside Relief 1 1z3o 0.1 Interceptor but not the other way around.The two lines subsequently run in a southerly direction along Los Alamitos Boulevard for approximately 10,800 feet. Westside Pump Station and Force Main The Westside Pump Station is located at 3112 Yellowtail Drive in the community of Rossmoor.The pump station underwent a major renovation in 2008(Project 3-52).This Project consisted of rehabilitating the existing pump station to meet then-current OCSD standards and national and state codes. In addition, the station's capacity was increased to meet then-projected peak wet-weather flows.The work included modification of the ventilation systems,control systems,and the station's structure and isolation of the pump and electrical rooms from one another.The mechanical equipment was relocated 30 feet below ground.The building underwent some minor modifications,and the roof was upgraded.The front gate was moved to the east of the property to ease access into the pump station.Additional landscaping was installed to enhance the front of the facility. Orange-Western Sub-trunk The Orange-Western Sub-trunk,constructed in 1959, is 13,940 feet long and has 38 manholes.The pipe is 21 inches in diameter.The Orange-Western Sub-trunk consists of two segments.The first segment begins just north of the intersection of Crescent Avenue and Western Avenue in the City of Buena Park. The pipeline continues south on Western Avenue and turns west on West Orange Avenue before connecting to the Knott Interceptor.The second segment continues west on West Orange Avenue from the Knott Avenue intersection to the Miller Holder Trunk Sewer at the Valley View Street intersection. Seal Beach Boulevard Interceptor The Seal Beach Boulevard Interceptor,constructed in 1970,is 5,530 feet long and has 8 manholes.The pipe is 51 inches in diameter.The Seal Beach Boulevard Interceptor begins just south of the Westside Pump Station at the end of Old Ranch Parkway in the City of Seal Beach.The pipeline continues south across the Interstate 405(1-405)freeway right-of-way and in North Gate Road south of 1-405 until merging with Seal Beach Boulevard.The pipeline then continues south along Seal Beach Boulevard until it reaches the Seal Beach Pump Station located at the intersection of Seal Beach and Westminster Boulevards.The Seal Beach Naval Weapons Station extends to the centerline of Seal Beach Boulevard. Approximately 3,500 feet of Seal Beach Boulevard Interceptor is within an easement on land owned by the United States Navy. 2.2 Purpose and Objectives The Western Regional Sewer pipelines have exceeded their functional life and have developed deficiencies that have led to the intrusion of groundwater and,in some cases, hard calcium deposits which make the pipes hard to clean and impede wastewater flow.Also, portions of both the Los Alamitos Sub-trunk(15,540 linear feet)and the Westside Relief Interceptor(16,010 linear feet)are considered capacity deficient, are unable to handle projected 2040 wet weather flows,and need to be upsized to minimize the existing surcharging potential. Further,the Westside Pump Station wet well was 2 123o 0.1 renovated in 2008 to extend its serviceable life.The repairs to the wet well are nearing the end of their expected life,and the wet well needs to be replaced. The purpose of the proposed Project is to increase the life of the Western Regional Sewers within the western region of OCSD's service area by another 50 years and to ensure that the projected 2040 wet weather peak flows(10-Year Storm)would be adequately contained. Objectives for the proposed Project include the following: • Extend the service life of the Western Regional Sewers by either rehabilitation of the existing lines or replacement of the lines on new alignment within the same streets; • Replace the Westside Pump Station wet well to prevent future failure and release of sewage to the environment; • Accommodate projected 2040 wet weather peak flows(10-Year Storm); • Minimize impacts to the environment; • Minimize existing surcharging in new/rehabilitated pipes; • Minimize groundwater intrusion in new/rehabilitated pipes;and • Reduce potential for odors. Without rehabilitation of the Western Regional Sewers and implementation of the Westside Pump Station improvements,the potential for groundwater intrusion and surcharging would continue and the wet well would further degrade.Additionally,OCSD would not meet requirements to accommodate projected 2040 wet weather flows, potentially resulting in unplanned sanitary sewer releases to the environment. SECTION 2: ENVIRONMENTAL REVIEW PROCESS OCSD is the Lead Agency approving the Project and conducting environmental review under CEQA (California Public Resources Code Sections 21000,et sec.),and the Guidelines promulgated thereunder in California Code of Regulations,Title 14,Sections 15000 et seq(CEQA Guidelines). Pursuant to CEQA Guidelines section 15084(d)(3), OCSD retained a consultant,Jacobs,to assist with the preparation of CEQA environmental documents.OCSD has reviewed and edited as necessary the submitted drafts and hereby certifies that the Final Environmental Impact Report(Final EIR or FEIR) reflects its own independent judgment and analysis under CEQA Guidelines Section 15090(a)(3)and Public Resources Code Sections 21082.1(a)-(c). In November 2015,OCSD published a CEQA Initial Study for the proposed Project and determined that preparation of an Environmental Impact Report(EIR)was necessary. OCSD prepared and published a Draft Environmental Impact Report(Draft EIR or DEIR)in October 2016,in compliance with CEQA,and filed a Notice of Completion with the Governor's Office of Planning and Research,State Clearinghouse, indicating that the DEIR had been completed and was available for review and comment by the public. Pursuant to Section 15082 of the CEQA Guidelines,OCSD also published a Notice of Availability on October 17,2016,which began a 45-day period for public and agency comments on the Project DEIR.A public notice was placed in the Orange County Register, Orange County Breeze,and Seal Beach Sun 3 123o 0.1 News general circulation newspapers on October 17,2016, informing the public of the availability of the DEIR and that a public meeting would be held during this comment period.Copies of the DEIR were also made available on October 17,2016,for public review at the following locations: • OCSD,Administrative Office, 10844 Ellis Avenue, Fountain Valley,CA • Los Alamitos-Rossmoor Library, 12700 Montecito Road,Seal Beach,CA • La Palma Library,7842 Walker Street, La Palma,CA • Seal Beach/Mary Wilson Library,707 Electric Avenue,Seal Beach,CA • Cypress Library,5331 Orange Avenue, Cypress, CA • Fountain Valley Library, 17635 Los Alamos Street, Fountain Valley,CA • Anaheim Central Library,500 West Broadway,Anaheim,CA • Buena Park Library,7150 La Palma Avenue,Buena Park,CA Pursuant to the CEQA Guidelines,Section 15083,a public meeting was held on November 17, 2016 at 6:00 p.m. at the Los Alamitos Community Center in the City of Los Alamitos.The meeting was held to provide the public an opportunity to voice comments or concerns regarding potential effects of the proposed Project and the issues included in the EIR. With the exception of an attorney from Cox,Castle & Nicholson LLP representing Forest Lawn Cemetery,no other members of the public, community groups,or public agencies attended the meeting. The FEIR for the Project was published in February 2017.The FEIR includes responses to comments received during the public comment period.The FEIR was prepared in accordance with CEQA Guidelines. The FEIR is intended to serve as an informational document for public agency decision-makers and the general public regarding the objectives and components of the Project.The FEIR addresses the potential significant environmental impacts associated with the Project,and identifies feasible mitigation measures and alternatives that may be adopted to reduce or eliminate these impacts.The DEIR and FEIR are incorporated by reference into this CEQA findings document. The FEIR is the primary reference document for the formulation and implementation of a mitigation monitoring and reporting program (MMRP)for the Project. Environmental impacts cannot always be mitigated to a level that is considered less than significant. In accordance with CEQA,if a lead agency approves a project that has significant unavoidable impacts that cannot be mitigated to a level below significance,the agency must state in writing the specific reasons and overriding considerations for approving the project based on the final CEQA documents and any other information in the public record for the project(CEQA Guidelines, § 15093).This is called a "statement of overriding considerations." The documents and other materials that constitute the record of proceedings on which OCSD's CEQA findings are based are located at the OCSD Administrative Office Building at 10844 Ellis Avenue, Fountain Valley,CA 92708,and on the OCSD website at www.ocsd.com.This information is provided in compliance with CEQA Guidelines Section 15091(e). 4 123o 0.1 SECTION 3: FINDINGS 3.1 Introduction CEQA requires that the lead agency adopt mitigation measures or alternatives where feasible to avoid or mitigate significant environmental impactsthat would otherwise occurwith the implementation of the Project. Project mitigation or alternatives are not required,however,where they are infeasible or where a mitigation measure is within another agency's responsibility and jurisdiction (CEQA Guidelines§ 15091(a)). For those significant impacts that cannot be mitigated to a less than significant level,the lead agency is required to find that specific overriding economic, legal,social,technological,or other benefits of the proposed Project outweigh the significant effects on the environment(Public Resources Code§ 23081(b)and CEQA Guidelines§ 15093). If such findings can be made,the CECIA Guidelines state in Section 15093(a)that"the adverse environmental effects may be considered acceptable."CECIA also requires that the findings made pursuant to CEQA Guidelines Section 15091 be supported by substantial evidence in the record (CEQA Guidelines, § 15091(b)). Under CEQA,substantial evidence means enough relevant information has been provided (reasonable inferences from this information may be made)to support a conclusion, even though other conclusions might also be reached. Substantial evidence includes facts, reasonable assumptions predicated on facts,and expert opinion supported byfacts (CEQA Guidelines,§15384). The findings reported in the following pages incorporate the facts and discussions in the DEIR for the Project as fully set forth therein. For each of the significant impacts identified in the DEIR,the following sections are provided: • Description of Significant Effects:A specific description of the environmental effects identified in the EIR, including a conclusion regarding the significance of the impact. • Mitigation Measures: Identified feasible mitigation measures oractions,that are required as part of the Project,and if mitigation is infeasible,the reasons supporting the finding that the mitigation is infeasible. • Rationale:A summary of the reasons for the finding(s). • Reference: A citation to the specific section in the EIR addressing the identified impact including the evidence supporting the finding. For environmental effects that are identified in the DEIR as no impacts or less than significant impacts and do not require mitigation, a statement explaining why the impacts are less than significant is provided. 3.2 Environmental Impacts that are Less than Significant and Do Not Require Mitigation Certain resource-specific impacts, identified in Appendix G of the CEQA Checklist, were evaluated previously in the Initial Study for the proposed Project(DEIR Appendix A). As a result of this Initial Study, it was determined that the proposed Project would result in no impacts to Agriculture and Forestry 5 1230 0.1 Resources, Mineral Resources, and Population and Housing. These environmental resource areas were not addressed further in the EIR. Finding: As a result of the analyses conducted for the DEIR, it was determined that the proposed Project would result in no impacts or less than significant impacts,and no required mitigation measures,for the following resource areas: • Geology and Soils(DEIR Section 3.5, pages 3-82 through 3-93) • Greenhouse Gas Emissions(DEIR Section 3.6,pages 3-94 through 3-104) • Public Services(DEIR Section 3.10, pages 3-207 through 3-210) • Recreation(DEIR Section 3.11,pages 3-211 through 3-215) • Traffic and Circulation (DEIR Section 3.12, pages 3-216 through 3-234) Rationale for Finding:The above finding is made based on the analyses presented in the aforementioned Draft EIR sections,which are incorporated by reference herein. 3.3 Environmental Impacts Found to be Less than Significant After Mitigation The following section lists significant impacts of the proposed Project along with corresponding mitigation measures identified in DEIR Chapter 3.0 that reduce these impacts to less than significant after mitigation. Implementation of these mitigation measures will be monitored and enforced in accordance with CEOA Guidelines Section 15097. Aesthetics AES-1: Would the Project substantially degrade the existing visual character or quality of the site and its surroundings? Finding: Implementation of the following mitigation measures will reduce Project-related impacts to less than significant. • AES MM I:OCSD will obtain interment schedules from the Forest Lawn Cemetery andtemporarily suspend construction activities for the Los Alamitos Sub-trunk within the Forest Lawn Cemetery during interment ceremonies to minimize construction disturbances to Forest Lawn operations. Visual screening will also be installed where work will occur within and adjacent to Forest Lawn in order to reduce temporary impacts to visitors associated with construction equipment and activities. • AES MM Ia: More disruptive construction requiring segments of open-cut trenching within the Forest Lawn property will be conducted at night, where feasible,to minimize significant impacts to visitors. • AES MM 2: Based on final design and prior to removal or trimming of any tree,OCSD will identify all trees that require removal or trimming. For trees located within the existing easement, OCSD will provide replacement in-kind landscaping surrounding the easement area for the 6 123o 0.1 corresponding municipality or private owner. The OCSD liaison to Forest Lawn will work with cemetery representatives during tree trimming, removal, and replacement within the cemetery property. Coordination with Forest Lawn will include identifying trees to be removed and trimmed prior to cutting, discussing trees of concern and protection options, and determining species,size and planting locations for replacement specimens outside of the existing easement. The size of replacement trees will be comparable to trees removed where possible and where site conditions allow. • AES MM 3: OCSD will limit construction hours for the Westside Pump Station to 8:00 a.m.to 5:00 p.m. Monday through Friday to minimize visual impacts of construction activities on adjacent residences, unless otherwise required for completion of construction activities or system operation,at which time adjacent property owners will be notified in advance. • AES MM 4:OCSD will erect visual screening along the property walls adjacent to the pump station and across the front of the pump station during construction activities at the Westside Pump Station to minimize visual impacts of construction activities on adjacent residences. Rationale for Findine:The above finding is made based on the analysis in Draft EIR Section 3.1 (pages 3-3 through 3-13),which is incorporated herein by reference. Construction and operation of the Project is temporary and would not substantially degrade the existing visual character or quality of the site and its surroundings. AES-2: Would the Project create anew source of substantial light or glare which would adversely affect day or nighttime views in the area? Finding: Implementation of the following mitigation measure will reduce Project-related impacts to less than significant. • AES MM 5: Should nighttime construction be required, OCSD will require that all lighting is focused and directed onto the work area only.OCSD will monitor lighting to ensure that there is no spillover to residential areas or other sensitive receptors. Rationale for Findine:The above finding is made based on the analysis in Draft EIR Section 3.1 (pages 3-3 through 3-13),which is incorporated by reference herein. Construction and operation of the Project would not create a new source of substantial light or glare which would adversely affect day or nighttime views in the area. Air Qualiri AQ-1:Would the project conflict with or obstruct implementation of the applicable air quality plan? Finding; Implementation of the following mitigation measure will reduce Project-related impacts to less than significant. • AQ MM 1: OCSD shall require its construction contractor, either through the use of scheduling, sequencing of equipment usage, or other means, to demonstrate that construction-related 7 1z3o 0.1 activities for all Project segments will not generate daily emissions exceeding the SCAQMD NO, threshold shown in DER Table 3.2-5. Rationale for Findin¢:The above finding is made based on the analysis in Draft EIR Section 3.2 (pages 3- 14 through 3-38 and Table 3.2.5),which is incorporated by reference herein. Construction and operation of the Project would not conflict with or obstruct implementation of the applicable air quality plan. AQ-2:Would the project violate any air quality standard or contribute substantially to an existing or projected air quality violation? Finding: Implementation of the following mitigation measure will reduce Project-related impacts to less than significant. • See AQMM1. Rationale for Finding:The above finding is made based on the analysis in Draft EIR Section 3.2 (pages 3- 14 through 3-38),which is incorporated by reference herein.Construction and operation of the Project would not violate any air quality standard or contribute substantially to an existing or projected air quality violation. AQ-3:Would the project result in a cumulatively considerable net increase of any criteria pollutant for which the project region is in nonattainment under an applicable federal or state ambient air quality standard(Including releasing emissions which exceed quantitative thresholds for ozone precursors)? Finding: Implementation of the following mitigation measure will reduce Project-related impacts to less than significant. • See AQMM1. Rationale for Finding:The above finding is made based on the analysis in Draft EIR Section 3.2 (pages 3- 14 through 3-38),which is incorporated by reference herein.Construction and operation of the Project would not result in a cumulatively considerable net increase of any criteria pollutant for which the Project region is in nonattainment under an applicable federal or state ambient air quality standard (including releasing emissions which exceed quantitative thresholds for ozone precursors). Biological Resources BIO-1: Would the project conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance? Finding: Implementation of the following mitigation measures will reduce Project-related impacts to less than significant: • AES MM 2: Based on final design and prior to removal or trimming of any tree,OCSD will identify all trees that require removal or trimming. For trees located within the existing easement, OCSD will provide replacement in-kind landscaping surrounding the easement area for the corresponding municipality or private owner. The OCSD liaison to Forest Lawn will work with 8 1230 0.1 cemetery representatives during tree trimming, removal, and replacement within the cemetery property. Coordination with Forest Lawn will include identifying trees to be removed and trimmed prior to cutting, discussing trees of concern and protection options, and determining species,size and planting locations for replacement specimens outside of the existing easement. The size of replacement trees will be comparable to trees removed where possible and where site conditions allow. • BID MM 1: Shrub and tree trimming and/or removal activities associated with the proposed Project shall generally be conducted outside the nesting season (February 15 through July 15). However, if shrub and tree removal must occur during the nesting season, a qualified wildlife biologist (as determined by California Department of Fish and Wildlife) shall conduct preconstruction surveys for nesting birds within suitable nesting habitat in the proposed Project area including a 300-foot buffer around the construction limits.The nesting bird surveys shall be conducted one week before initiation of construction activities within those habitats. If no active nests are detected during surveys,construction may proceed. If active nests are detected,then a no-disturbance buffer shall be established around nests identified during preconstruction surveys. The extent of the no-disturbance buffer shall be 50 feet for non-raptors and 300 feet for raptors. (These buffer distances may be altered by a qualified biologist depending on the level of noise or construction disturbance, line of sight between the nest and the disturbance, ambient levels of noise and other disturbances, and other topographic or artificial barriers.These buffers shall be maintained until after the breeding season has ended or until the biologist determines that the young have fledged. Within this buffer, all nonessential construction activities (e.g., equipment storage, meetings)shall be avoided; however, construction activities can proceed if the biologist determines that the nesting birds are not likely to abandon the nest during construction. Rationale for Findine:The above finding is made based on the analysis in Draft EIR Section 3.3 (pages 3- 40 through 3-47),which is incorporated herein by reference.Construction and operation of the Project would not conflict with any local policies or ordinances protecting biological resources,such as a tree preservation policy or ordinance. Cultural Resources CUL-1: Would the project cause a substantial adverse change in the significance of a historical resource as defined in Section 15064.5? Finding: Implementation of the following mitigation measures will reduce Project-related impacts to less than significant: • CUL MM 3: Final design of the Los Alamitos Sub-trunk within Forest Lawn shall avoid disturbance of historic buildings,structures,or objects on the Forest Lawn property that are outside the OCSD easements.These include the Ascension Mausoleum;the Church of Our Fathers;the Main Mortuary Building;the park's maintenance facilities building; and the park entrance,and generally the memorial tablets,grave markers,stones,statues,and ornaments. • CUL MM 4: OCSD shall work with Forest Lawn Cemetery to ensure that pipeline alignment will remain within the existing alignment within OCSD easements,Guardian Drive,or other locations 9 1z3o 0.1 to avoid disturbance of existing interments immediately adjacent to the easements. Pipe realignment shall be coordinated with Forest Lawn Cemetery management prior to implementation.Alignments within existing easements will not require Forest Lawn approval, but Project managers shall coordinate with Forest Lawn managers regarding Project details within Forest Lawn property. • CUL MM 5: For the portion of the Los Alamitos Sub-trunk within Forest Lawn Cemetery, the contractor shall avoid disturbance of interment ceremonies and gravesites through the use of protective barriers,visual aids (i.e., signs, flagging, etc.) and defined exclusion areas on plans to provide mutually acceptable distance between construction areas and interments,as determined in consultation with Forest Lawn Cemetery management.Visual aids shall distinguish ornamental or structural elements from locations of known gravesites. • CUL MM 6: OCSD shall provide a liaison during construction of the Los Alamitos Sub-trunk within Forest Lawn Cemetery. Although disturbance to existing gravesites is not anticipated, should graves be impacted by construction,the OCSD liaison shall take immediate action to notify Forest Lawn and prevent further disturbance. The liaison will notify project managers and the Forest Lawn management should graves be disturbed. The Project managers shall consult with Forest Lawn management to determine the appropriate course of action in the event that impacts to gravesites are anticipated or, if they occur,in order to avoid any further disturbance. Rationale for Findin¢:The above finding is made based on the analysis in Draft EIR Section 3.4(pages 3- 48 through 3-81),which is incorporated herein by reference.Construction and operation of the Project would not cause a substantial adverse change in the significance of a historical resource as defined in Section 15064.5.

Rationale for Finding:The above finding is made based on the analysis in Draft EIR Section 3.4(pages 3- 48 through 3-81),which is incorporated herein by reference.Construction and operation of the Project should not disturb any human remains, including those interred outside formal cemeteries. Hazards/Hazardous Materials HAZ-1: Would the project emit hazardous emissions or handle hazardous or acutely hazardous materials,substances,or waste within 0.25 mile of an existing or proposed school? HAZ-2: Would the project be located on a site which is included on a list of hazardous materials sites compiled pursuant to Government Code Section 65962.5;and, as a result, would it create a significant hazard to the public or the environment? HAZ-3: Would the project impair implementation oforphysically interfere with an adopted emergency response plan or emergency evacuation plan? Finding: Implementation of the following mitigation measures will reduce Project-related impacts to less than significant: • HAZ MM 1: The contractor shall be responsible for providing trained personnel for monitoring and operation of construction activities and spill management, including cleanup and replacement of damaged property and fines. In the event an unauthorized spill occurs during construction activities, the contractor shall contact the appropriate agencies for cleanup and disposal pursuant to all applicable federal,state, and local laws and regulations. Rationale for Finding:The above finding is made based on the analysis in Draft EIR Section 3.7(pages 3- 105 through 3-128),which is incorporated by reference herein. Construction and operation of the ' Please note: Since the publication and circulation of the IS/NOP, recently adopted legislative amendments to the CEOA Checklist have created a separate Tribal Cultural Resource impact category (see separate finding below).The significance question contained in the revised checklist is, "Have California Native American tribes traditionally and culturally affiliated with the project area requested consultation pursuant to Public Resources Code section 21080.3.1?If so, has consultation begun?' As discussed in DEIR Section 3.4.4.3 Construction Impacts, consultation with Native American Tribes has been initiated (see DEIR Appendix AI and,to date,two tribes have expressed interest in the Project. OCSD will provide for the presence of a tribal on-site monitor in response to AB 52 consultations.Thus, the DEIR met the letter and intent of the amended CEOA Checklist. 12 12300,10.1 Project would not result in or create a significant hazard to the public or the environment associated with hazards or hazardous materials. Land Use and Planning LU-1:Would the project conflict with existing plans or regulations pertaining to nighttime construction lighting and noise where sensitive land uses are affected? Finding: Implementation of the following mitigation measures will reduce Project-related impacts to less than significant: • See AES MM 5. • See AQ MM 1. • NOI MM I:OCSD will require the contractor to prepare a Noise Control Plan(NCP)demonstrating noise reduction,at minimum of 5 dBA to 30 dBA and below the 90-dBA Federal Transit Authority threshold, prior to commencing any construction.The NCP will specifically address noise control near sensitive receptors and for construction for which a variance has been obtained from the appropriate jurisdiction (e.g., weekend and nighttime construction). The NCP will identify the location of noise-sensitive receptors and list the types of noise control measures proposed (e.g., sound blankets and temporary noise barriers providing 5 dBA to 23 dBA of noise reduction) and any conditions specified in the variance. Once approved by OCSD,the contractor will be required to implement the plan. To ensure compliance with the NCP, the contractor will be required to monitor all construction noise for activities potentially affecting sensitive receptors in areas approved by variance, as well as all schools, hospitals,convalescent homes, churches, and other noise-sensitive areas within 1,000 feet of the construction activities. If construction activities take place during weekend and nighttime hours near sensitive receptors that have activities occurring on site during these times, coordination will be conducted with the site owners/managers to ensure adequate measures are taken to reduce or avoid noise impacts. • NOI MM 2:The contractor will adhere to the specified hours in all local ordinances when construction activities are permitted.A variance will be required prior to construction if activities are planned to occur outside the permitted hours.OCSD will comply with any conditions specified in the variance.The following will minimize noise generated by all construction activities: o All construction equipment shall be maintained according to manufacturer's specifications and inspected regularly. o All noise-producing construction equipment shall be equipped with muffling devices, quiet use generators,or other equivalent noise-reducing features to minimize temporary noise. o Stationary sources shall be located a minimum of 25 feet(the closest distance used to estimate construction noise impacts)from noise-sensitive receptors, unless otherwise constrained by site-specific conditions. 13 I23o 0.1 o The use of noise-producing signals such as horns,whistles,alarms,bells, etc.shall be in accordance with federal, state, and local regulations. o Sound blankets and temporary sound barriers shall be located adjacent to construction activities where noise impacts above the regulated maximum levels are anticipated near noise-sensitive receptors. Rationale for Findine:The above finding is made based on the analysis in Draft EIR Section 3.8(pages 3- 142 through 3-160),which is incorporated by reference herein. Construction and operation of the Project would not conflict with existing plans or regulations pertaining to nighttime construction lighting and noise where sensitive land uses are affected. Noise NOI-2: Would the project expose persons to or generation of excessive groundborne vibration or groundborne noise levels? Finding: Implementation of the following mitigation measures will reduce Project-related impacts to less than significant: • See NOI MM 1. • See NOIMM2. • NOI MM 3: The following will minimize vibration generated from construction activities: o Route heavily loaded trucks away from residential streets. o Operate earthmoving or other construction equipment with the potential to create vibration-induced impact as far away from vibration-sensitive sites as construction location-specific conditions allow. o Pile-driving equipment for shoring installation, if utilized,will be of a non-vibratory type, will have short starting and stopping capabilities and will be able to operate at high revolutions. In addition,soil particle velocity will be monitored during the use of such equipment. If any vibration levels are measured above the 0.20 IPS threshold level, construction will be stopped immediately. Rationale for Findin¢:The above finding is made based on the analysis in Draft EIR Section 3.9 (pages 3- 169 through 3-193),which is incorporated by reference herein. Construction and operation of the Project would not expose persons to or generation of excessive groundborne vibration or groundborne noise levels. Tribal Cultural Resources TRI CUL-1: Would the project cause a substantial adverse change in the significance of a tribal cultural resource, defined in Public Resources Code Section 21074 as either a site, feature, place, cultural landscape that is geographically defined in terms of the size and scope of the landscape,sacred place, or object with cultural value to a California Native American tribe,and that is listed or eligible for listing 14 1230 0.1 in the California Register of Historical Resources, or in a local register of historical resources as defined In Public Resources Code section 5020.1(k(? Finding: Implementation of the following mitigation measures will reduce Project-related impacts to less than significant: • See CUL MM 1. • See CUL MM 7. • See CUL MM 8. Rationale for Finding:The above finding is made based on the analyses in Draft EIR Section 3.4(pages 3- 48 through 3-81), as well as FEIR Section 3.13 (Tribal Cultural Resources, Pages 3-234 through 3-244), which are incorporated by reference herein.Construction and operation of the Project would not cause a substantial adverse change in the significance of a tribal cultural resource. TRI CUL-2: Would the project cause a substantial adverse change in the significance of a tribal cultural resource, defined in Public Resources Code Section 21074 as either a site,feature,place,cultural landscape that is geographically defined in terms of the size and scope of the landscape,sacred place, or object with cultural value to a California Native American tribe, and that is a resource determined by the lead agency,in its discretion and supported by the substantial evidence, to be significant pursuant to criteria set forth in subdivision(c)of Public Resources Code Section 5024.1?In applying the criteria set forth in subdivision(c)of Public Resource Code Section 5024.1, the lead agency shall consider the significance of the resource to a California Native American tribe. Finding: Implementation of the following mitigation measures will reduce Project-related impacts to less than significant: • See CUL MM I. • See CUL MM 7. • See CUL MM 8. Rationale for Finding:The above finding is made based on the analyses in Draft EIR Section 3.4(pages 3- 48 through 3-81), as well as FEIR Section 3.13(Tribal Cultural Resources, Pages 3-234 through 3-244), which are incorporated by reference herein.Construction and operation of the Project would not cause a substantial adverse change in the significance of a tribal cultural resource. 3.4 Environmental Impacts Found to be Significant and Unavoidable 15 1230 0.1 Noise N0I4: Would the project result in a substantial temporary or periodic increase in ambient noise levels in the project vicinity above the ambient noise conditions? Finding: Implementation of mitigation measures NOI MM 1,NOI MM 2, and NOI MM 3 would reduce noise and vibration levels during construction and operation;however,even with these measures, significant noise during construction,as identified in Impact NOI-4,would still occur. Impact NOI-4 remains a significant and unavoidable impact after implementation of the following mitigation measures: • See NOI MM 1. • See NOI MM 2. • See NOI MM 3. Rationale for Finding: The above finding is made based on the analysis in Draft EIR Section 3.9 (pages 3- 169 through 3-206),which is incorporated by reference herein.Construction and operation of the Project would result in a substantial temporary or periodic increase in ambient noise levels in the Project vicinity above the ambient noise conditions,which could not be mitigated to a less than significant level. 3.5 Findings Regarding Project Alternatives The DER analyzed two build alternatives,as well as the No Build/No Project alternative.The two build alternatives consisted of: • Build Alternative 1:Replace portions of the existing Los Alamitos Sub-trunk and Westside Relief Interceptor with new, larger capacity pipe.This build alternative would also rehabilitate portions of the existing Los Alamitos Sub-trunk and Westside Relief Interceptor sewer pipe in- place. In addition, Build Alternative 1 would rehabilitate the Orange-Western Sub-trunk and Seal Beach Boulevard Interceptor pipelines in-place. Further, Build Alternative 1 would rehabilitate the Westside Pump Station force main and wet well. • Build Alternative 2:Replace the entire Los Alamitos Sub-trunk pipeline with new, larger capacity pipe.This build alternative also would divert all flow from the Westside Relief Interceptor north of Orange Avenue to an enlarged Los Alamitos Sub-trunk via a new diversion structure. In addition, Build Alternative 2 would rehabilitate the entire length of the Westside Relief Interceptor in-place. Further, Build Alternative 2 would rehabilitate the Westside Pump Station force main and wet well. Finding: Build Alternative 1 is the Environmentally Superior Alternative. Rationale for Finding: On the basis of the analyses presented in the DER,of the two alternatives considered, Build Alternative 1 is considered to be the Environmentally Superior Alternative due to its lower potential for construction-related impacts associated with air quality, noise,and traffic relative to Build Alternative 2. 16 123o 0.1 Cumulative Effects Section 15355 of the California Environmental Quality Act(CEQA) Guidelines defines cumulative impacts as"two or more individual effects which,when considered together,are considerable or which compound or increase other environmental impacts." Section 15130 of the CEQA Guidelines provides guidance for analyzing significant cumulative impacts in an EIR. According to Section 15130(b)of the CEQA Guidelines,cumulative impact analysis may be conducted and presented by either of two methods: (1) a list of past, present, and probable projects producing related or cumulative impacts; or(2) a summary of projections contained in an adopted general plan or related planning document, or in a prior environmental document that has been adopted or certified, which described or evaluated regional or area-wide conditions contributing to the cumulative impact. The cumulative list approach was utilized in the analyses conducted for the DEIR for the following resource areas: • Aesthetics(DEIR Section 4.1.2, pages 4-3 through 4-4) • Air Quality(DEIR Section 4.1.3, page 4-4) • Biological Resources(DEIR Section 4.1.4, page 4-5) • Cultural Resources(DEIR Section 4.1.5, page 4-5) • Geology and Soils(DEIR Section 4.1.6,page 4-6) • Greenhouse Gas Emissions(DEIR Section 4.1.7, page 4-6) • Hazards/Hazardous Materials(DEIR Section 4.1.8,page 4-7) • land Use and Planning(DEIR Section 4.1.9, pages 4-7 through 4-8) • Noise(DEIR Section 4.1.10, page 4-8) • Public Services(DEIR Section 4.1.11, page 4-9) • Recreation(DEIR Section 4.1.12, page 4-9) • Traffic and Circulation(DEIR Section 4.1.13, pages 4-9 through 4-10) • Tribal Cultural Resources(FEIR Section 4.1.14, pages 4-10 through 4-11) Finding: The Project would not result in cumulatively considerable impacts. Rationale for Finding: On the basis of the analyses presented in the DEIR(Section 4.1.2 through 4.1.13), as well as the FEIR (Section 4.1.14), which are incorporated herein by reference, construction and operation of the Project would not result in cumulatively considerable impacts to the above referenced resources. 3.6 Findings Regarding Other CEQA Considerations Significant and Unavoidable Environmental Impacts(DEIR Section 5.1.page 5-1) 17 123v 0.1 As described in DEIR Chapter 3.0, the proposed Project would result in significant impacts related to Aesthetics (3.1), Air Quality (3.2), Biological Resources (3.3), Cultural Resources (4.4), Hazards and Hazardous Materials (3.7), Land Use/Planning (3.8), and Noise (3.9). With the exception of temporary construction-related noise impacts, all of these significant impacts would be reduced to below a level of significance through implementation of mitigation measures,as described in each section. Finding: The Project would result in one significant and unavoidable environmental impact. As noted in Section 3.4 of these findings, the proposed Project would result in temporary increases in ambient noise levels during construction (Impact NOI-4),which would remain significant and unavoidable after mitigation. As a result, Impact NOI-4 would be the only significant and unavoidable environmental impacts associated with the proposed Project. Rationale for Finding: The above finding is made based on the analysis in Draft EIR Section 3.9 (pages 3- 169 through 3-206),which is incorporated by reference herein.Construction and operation of the Project would result in a substantial temporary or periodic increase in ambient noise levels in the Project vicinity above the ambient noise conditions,which could not be mitigated to a less than significant level. Growth Inducing Impacts(DEIR section 5.2, pages 5-1 through 5-2) Finding: The Project would not result in growth-inducing impacts. Rehabilitation and/or replacement of the Western Regional Sewers and improvements to the Westside Pump Station would not directly or indirectly induce substantial population growth in the area because the proposed Project involves rehabilitation and/or replacement of the Western Regional Sewers and new construction to replace a wet well at an existing pump station;these components have exceeded their functional life.Capacity-deficient segments,as identified in DEIR Section 2.3, Purpose and Objectives,would be increased to accommodate 2040 wet weather peak flows(10-Year Storm). Rationale for finding: The above finding is based on the analyses in Draft EIR Section 5.2 (pages 5-1 through 5-2)and in Section 4.13 of the Initial Study(DEIR,Appendix A),which are incorporated by reference herein.The proposed rehabilitation and/or replacement segments would not increase the capacity of the system, as the pipes would be replaced in-kind with no increase in pipe diameter and would not directly or indirectly induce substantial growth. Energy Conservation Finding: The proposed Project would not result in wasteful, inefficient,and unnecessary consumption of energy. The guidance on energy conservation in CEQA Guidelines Appendix F is based on the statutory requirement that the mitigation measures in an EIR include"measures to reduce the wasteful, inefficient, and unnecessary consumption of energy'(Public Resources Code Section 21100(b)(3)). Consistent with this mandate,CEQA Guidelines Appendix F lists possible energy impacts and potential 18 123o 0.1 conservation measures that should be considered in an EIR when they are"applicable or relevant to the project" and the impacts are"potentially significant."Appendix F does not mandate the analysis of particular energy-related impacts or include specific significance criteria by which to measure a project's energy impacts. For the purposes of the DEIR analysis,consideration is given to whether the Project would result in the wasteful, inefficient,or unnecessary consumption of energy. Rationale for Findin¢:The above finding is made based on the analysis in Draft EIR Section 5.3 (pages 5-2 through 5-3),which is incorporated herein by reference.Construction and operation of the Project would not result in wasteful,inefficient,and unnecessary consumption of electricity or diesel fuel. 3.7 Findings Regarding Responses to Comments and Revisions in the Final EIR Chapter 8 was added to the Final EIR to include the comment letters submitted during the public review period of the Draft EIR and responses to those comments, in accordance with California Environmental Quality Act(CEQA)Guidelines,Section 15088. The 45-day review period for the Draft EIR began on October 17,2016,and concluded on December 1,2016. Comment letters were received from the following seven public agencies and other interested parties during the review period: • Orange County Fire Authority • Orange County Public Works, Orange County Development Services • Orange County Transportation Authority • Los Alamitos Unified School District • Cox, Castle&Nicholson LLP on behalf of Forest Lawn Memorial-Park Association • State of California Native American Heritage Commission • Gabrieleno Band of Mission Indians—Kizh Nation The FEIR incorporates the Draft EIR prepared by OCSD,the comments and recommendations received on the DEIR, and revisions to the DEIR by the Lead Agency in response to significant environmental points raised in the review and consultation process(Chapter 8), minor revisions to the text included as part of the record by OCSD, and the addition of Chapter 9,the Mitigation Monitoring and Reporting Program. Based on the responses to comments and revisions in the FEIR,the Board finds the comments and recommendations on the DEIR were adequately responded to and no new significant and unavoidable environmental impacts were raised, and that the mitigation measures identified in this FEIR have been incorporated into a mitigation monitoring and reporting program to ensure that they are implemented. SECTION 4:STATEMENT OF OVERRIDING CONSIDERATIONS 19 tz3o 0.1 CEQA requires a public agency to balance the benefits of a project against its unavoidable,adverse environmental impacts in determining whether to approve the project. Section 15093 of the State CEQA Guidelines provides the following: "(a) CEQA requires the decision-making agency to balance,as applicable, the economic, legal,social, technological,or other benefits of a proposed project against its unavoidable environmental risks when determining whether to approve the project. If the specific economic, legal,social, technological,or other benefits of a proposed project outweigh the unavoidable adverse environmental effects, the adverse environmental effects may be considered "acceptable." (b)When the lead agency approves a project which will result in the occurrence of significant effects which are identified in the Final Environmental Impact Report(Final EIR)but are not avoided or substantially lessened, the agency shall state in writing the specific reasons to support its action based on the Final EIR and/or other information in the record. The statement of overriding considerations shall be supported by substantial evidence in the record. (c)If an agency makes a statement of overriding considerations, the statement should be included in the record of the project approval and should be mentioned in the notice of determination. This statement does not substitute for, and shall be in addition to,findings required pursuant to Section 15091." As set forth in the preceding sections,OCSD's approval of the Rehabilitation of the Western Regional Sewers, Project No. 3-64 will result in a significant environmental impact that cannot be avoided even with the adoption of all feasible mitigation measures.Whenever a lead agency adopts a project which will result in a significant and unavoidable impact,the agency must, pursuant to Public Resources Code sections 21002 and 21081(b)and State CEQA Guidelines section 15093,state in writing the specific reasons to support its action based on the FEIR and/or other information in the administrative record. As documented in the DEIR and as explained in these Findings,the Project will potentially result in one significant and unavoidable impact to the environment as follows: NO1-4: The Project would result in a substantial temporary or periodic increase in ambient noise levels in the Project vicinity above the ambient noise conditions during construction. The OCSD Board has balanced the Project's benefits against the Project's significant unavoidable noise impact.The Board finds that the Project's benefits outweigh the Project's temporary construction- related significant unavoidable impact,and therefore finds that the Project's significant unavoidable impact is acceptable.The Board finds that each of the following benefits is an overriding consideration, independent of the other benefits,that warrants approval of the Project notwithstanding the Project's significant and unavoidable impact. The proposed Project would: • Extend the service life of the Western Regional Sewers • Prevent potential for future failure and release of sewage to the environment 20 123o 0.1 • Accommodate projected 2040 wet weather peak flows(10-Year Storm) • Minimize impacts to the environment • Minimize existing surcharging in new/rehabilitated pipes • Minimize groundwater intrusion in new/rehabilitated pipes • Reduce potential for odors SECTION 5:ADOPTION OF MITIGATION MONITORING AND REPORTING PROIGRAM Pursuant to Public Resources Code Section 21081.6, a public agency making findings required by subdivision (a) of Section 21081 must adopt a reporting and monitoring program for the changes to the Project which have been adopted or made a condition of project approval in order to mitigate or avoid significant effects on the environment. The Board hereby adopts the Mitigation Monitoring and Reporting Program.The Board further finds that said program meets the requirements of Public Resources Code Section 21081.6 by ensuring compliance during project implementation with the mitigation measures identified in the EIR. The Mitigation Monitoring and Reporting Program is attached to the OCSD Resolution adopting these Findings as Chapter 9 of Exhibit"A." CONCLUSIONS For the foregoing reasons,OCSD finds that the project's significant, unavoidable environmental impact associated with construction-related noise is outweighed by the above-referenced benefits,any one of which is individually sufficient to outweigh the significant, unavoidable environmental effect of the proposed Project.Therefore,the Board adopts these Findings and Statement of Overriding Considerations. 21 1230 0.1 BOARD OF DIRECTORS Meeting Date TOBE.Or Dir. -- 03/22/17 AGENDA REPORT Item Item 13 Orange County Sanitation District FROM: James D. Herberg, General Manager Originator: Rob Thompson, Director of Engineering SUBJECT: CARBON CANYON CLAY PIPE REPAIRS, PROJECT NO. FE16-08 GENERAL MANAGER'S RECOMMENDATION Authorize the General Manager to receive and review bids, and award a construction contract to the lowest responsive, responsible bidder for an amount not to exceed $800,000 for the Carbon Canyon Clay Pipe Repairs, Project No. FE16-08. BACKGROUND The Orange County Sanitation District (Sanitation District) owns and maintains a trunk sewer system that drains a portion of the northeast section of Brea. A segment of this sewer line, located east of Rose Drive and south of Carbon Canyon Road in the City of Brea, was constructed in 2009 using vitrified clay pipe furnished by two different manufacturers. In a recent inspection, Sanitation District staff identified severe deterioration in 1,600 feet of this segment of 33-inch pipe that warrants immediate repair. The portions where deterioration has occurred were all manufactured by Mission Clay. Piping provided by the other supplier has not shown any signs of degradation. The Sanitation District is aware of three other wastewater agencies that have experienced similar defects in vitrified clay pipe manufactured by Mission Clay of similar sizes installed about the same time period. Staff has been in consultation with legal counsel and may pursue a claim for the repair costs from Mission Clay if proposed testing determines that there were defects in the manufacturing process of the defective pipe. RELEVANT STANDARDS • Operate and maintain facilities to minimize impacts on surrounding communities, including odor, noise, and lighting. • Less than 2.1 sanitary sewer spills per 100 miles. • CA Public Contract Code Section 20103.8, award construction contract to lowest responsive, responsible bidder. Page 1 of 3 PROBLEM A segment of the Carbon Canyon trunk sewer is severely deteriorated. The walls of the pipeline in some areas have deteriorated to the extent that the soil backfill can be seen from the inside of the pipe. The pipe is failing and needs to be repaired as soon as possible to avoid collapse and complete blockage. PROPOSED SOLUTION Carbon Canyon Clay Pipe Repairs, Project No. FE16-08, will install a structural cured-in- place liner for the entire segment of the defective pipeline. This action will authorize the General Manager to award a construction contract for the Carbon Canyon Clay Pipe Repairs, Project No. FE16-08, to the lowest responsive, responsible bidder. TIMING CONCERNS The schedule driver for this project is to repair the deteriorated segment of pipeline prior to further reduction of its structural capability and increasing the risk of a collapse, which could potentially result in additional costly repairs. Award of the construction contract will allow the construction to begin sooner, minimizing the risk to public health and safety. RAMIFICATIONS OF NOT TAKING ACTION A delay in the award of the contract increases the risk of further deterioration or possible pipe failure. PRIOR COMMITTEE/BOARD ACTIONS N/A ADDITIONAL INFORMATION The Sanitation District expects to receive bids on March 16, 2017, after the date when this Agenda Report is mailed. Staff intends to present information on the bids received at this Board Meeting. The bids will be fully reviewed and evaluated in accordance with the Sanitation District's policies and procedures prior to award of the construction contract by the General Manager to the lowest responsive, responsible bidder. If there are any incurable irregularities with the bids, staff will return the issue to the Board for further direction. CEQA A Notice of Exemption will be filed following award of a construction contract by the General Manager. Page 2 of 3 FINANCIAL CONSIDERATIONS This request complies with authority levels of the Sanitation District's Purchasing Ordinance. This item has been budgeted.
