BACKGROUND The Orange County Sanitation District (Sanitation District) owns and operates the Bay Bridge Pump Station in the City of Newport Beach. It is located on West Coast Highway and is adjacent to the Newport Back Bay Channel. The force mains cross the channel and connect to the existing Newport Beach force main network. The volume of flow through the Bay Bridge Pump Station accounts for 50-60% of Newport Beach's wastewater. The pump station is surrounded by a storage and marine-use yard that will soon be developed into a three-story mixed-use residential, commercial, and boat storage space. The Bay Bridge Pump Station and associated force mains piping requires replacement to address aging infrastructure, comply with current safety and engineering standards, and increase the flow capacity of the station to accommodate future growth in the region. The existing system was built in 1966 and rehabilitated in 1992. The proposed Bay Bridge Pump Station and Force Mains Replacement Project will relocate and expand the current pump station and associated force mains. The Sanitation District is required to prepare a California Environmental Quality Act (CEQA) document to analyze the potential environmental impacts of the proposed project and project alternatives. The preferred alternative is to build a new pump station and force main system while the existing system is in operation. After completion, the existing pump station will be demolished and the restored site exchanged with the surrounding property owner so it Page 1 of 4 1276106A REVISED AGENDA REPORT can be used for the development. The proposed pump station site will allow safer access for maintenance personnel, the addition of an on-site odor control system, and be out of the public view from East Coast Highway and the proposed mixed-use development. The new force main system will require crossing under the Newport Back Bay Channel and East Coast Highway. RELEVANT STANDARDS • Listen to and seriously consider community input on environmental concerns • Meet CEQA and NEPA standards PROBLEM The pump station is over 50 years old and does not meet Sanitation District safety and engineering code standards. Access to the pump station is limited and poses a potential safety hazard for the Sanitation District. The planned construction of a three-story mixed-use development around the pump station will also require the addition of an on-site odor control system. The existing pump station force main piping is undersized, aging, cannot be maintained due to its location under the Back Bay channel, and is reaching the end of its useful life. Final Design for this project will commence once the Sanitation District demonstrates compliance with CEQA. PROPOSED SOLUTION Complete CEQA so the project may proceed into design, construction, and eventual completion. TIMING CONCERNS Constructing the new facilities in advance of the proposed surrounding development will allow more space for construction staging and have less community impacts. The surrounding property owner is planning to begin construction in early 2020. RAMIFICATIONS OF NOT TAKING ACTION The project cannot proceed without this environmental finding. PRIOR COMMITTEE/BOARD ACTIONS September 24, 2014 -Approve a Professional Services Agreement with RBF Consulting to provide engineering design services for Bay Bridge Pump Station and Force Mains Replacement Project, Project No. SP-178, for an amount not to exceed $475,308, and approve a contingency of$47,530 (10%). Page 2 of 4 1276106.1 REVISED AGENDA REPORT ADDITIONAL INFORMATION The project is transitioning into the preliminary design phase and the Sanitation District plans to advertise for construction bids by March 2019. Construction is expected to be completed by November 2023. CEQA The Sanitation District, as lead agency, prepared an Initial Study analyzing the project's potential environmental impacts. Based on the Initial Study, the Sanitation District determined that an Environmental Impact Report must be prepared for the project. The Sanitation District subsequently issued a Notice of Preparation (NOP) that was made available for a 30-day public review period from November 10, 2016 to December 9, 2016. The NOP was also submitted to the State Clearinghouse (State Clearinghouse No. 2016111031). A Draft Environmental Impact Report (Draft EIR) was developed and distributed for a 45-day public review period from June 21, 2017 to August 4, 2017. A public hearing was held on July 17, 2017. The Final Environmental Impact Report (Final EIR) (State Clearinghouse No. 2016111031) found that the project's significant environmental impacts can be avoided or reduced to less than significant levels through the adoption of mitigation measures. These conclusions are supported by additional findings by the Sanitation District that the proposed mitigation measures are feasible and will avoid or substantially reduce any significant environmental effects of the project. These findings are described in the Facts and Findings Regarding the Environmental Effects for the Bay Bridge Pump Station and Force Mains Replacement Project("Statement of Facts and Findings")that was prepared for this project and attached to Resolution No. OCSD 17-XX as Exhibit B. These mitigation measures are-identified in the Final EIR and Statement of Facts and Findings are described in the Mitigation Monitoring and Reporting Plan prepared for this project and included in the Final EIR. Because the project, as mitigated, poses no significant environmental impacts, CEQA does not require the Sanitation District to make additional findings regarding recommended project alternatives, or adopt a statement of Overriding Considerations in relation to this project. The Sanitation District received 14 comments on the Draft EIR, which are included as Section 2.0 of the Final EIR. The comments were from public agencies as well as members of the public. Pursuant to CEQA Guidelines Section 15088(c), the Final EIR includes written responses to those comments (Section 2.0). The proposed Resolution certifying the the—Final EIR adopting the required CEQA findings and adopting the Mitigation Monitoring and Reporting Program is attached for the Board of Directors' consideration and approval.

Statement of Facts and Findings ii December 2017 Final Environmental Impact Report Bay Bridge Pump Station and Force Mains Replacement Project 1.0 STATEMENT OF FACTS AND FINDINGS 1.1 INTRODUCTION The California Environmental Quality Act (CEQA) requires that a Lead Agency make and adopt certain findings prior to approving a project that may have a significant effect on the environment. The following Statement of Facts and Findings has been prepared in accordance with the California Environmental Quality Act (CEQA), Public Resources Code Section 21081, and CEQA Guidelines Section 15091. CEQA Guidelines Section 15091 (a) provides that: No public agency shall appears or eamy out a projectfor which an EIR has been certified which identifies one or mote significant environmental effects of the project unless the public agency makes one or more written findings for each of those significant effects accompanied by a brief explanation of the rationale for each finding. Public Resources Code Section 21081 and CEQA Guidelines Section 15091(a)require that a lead agency make one or more findings for each potentially significant impact identified in the EIR. There are three possible categories of findings to be included in the Statement of Facts and Findings pursuant to Section 15091 (a) of the CEQA Guidelines. These categories include: (1) Changes or alterations bare been required in,orincoiporated into,theproject which avoid or substantially lessen the sign firiont environmental effect as identified in the final EIR. (2) Such changer or alterations are within the responsibility and consdichon of another public agenry and not the agenry making the finding. Such changes have been adopted by such other agenry or can and should be adopted by such other agenry. (3) Sperific economic, kgal, social, technological, or other considerations, imludingprueirion of employment opportuni5es for highly trained workers, make infeasible the mitigation measures orproject alternatives identified in the final EIR If the lead agency determines that the project's potentially significant environmental effects can be reduced to less than significant levels through the incorporation of project changes or mitigation measures,the lead agency may adopt the findings and approve the project without making additional findings. If, however, the agency determines that the project will have a significant environmental effect that will not be avoided or substantially lessened, the agency must adopt a Statement of Overriding Considerations before approving the project. Where a project will cause unavoidable significant impacts, the Lead Agency may still approve a project where its benefits outweigh the adverse impacts. The Statement of Overriding Considerations allows the Lead Agency to set forth specific reasoning by which benefits are balanced against effects before approving the project. It is important to note that the Environmental Impact Report (EIR) prepared for the project detemined that no significant,unavoidable impacts would occur as a result of project implementation. Thus,this Statement of Facts and Findings will only address and analyze those impacts determined to be less than significant,or less than significant upon incorporation of mitigation. The OCSD, the CEQA Lead Agency,finds and declares that the proposed Bay Bridge Pump Station and Force Mains Replacement Project EIR has been completed in compliance with CEQA and the Sta cracm of Facts and Findings 1 December 2017 Final Environmental Impact Report Bay Bridge Pump Station and Force Mains Replacement Project CE,QA Guidelines. The OCSD finds and certifies that the EIR and this Statement of Facts and Findings were reviewed and information contained in the EIR and this Statement of Facts and Findings was considered prior to approving the proposed Bay Bridge Pump Station and Force Mains Replacement Project,herein referred to as the"project". Based upon its review of the EIR, the Lead Agency finds that the EIR is an adequate assessment of the potentially significant environmental impacts of the proposed project,represents the independent judgment of OCSD,and sets forth an adequate range of alternatives to this project. The Final EIR is composed of the following elements: • The Bay Bridge Pump Station and Force Mains Replacement Project Public Review Draft Environmental Impact Report Qune 2017); • Responses to Comments;and • Mitigation Monitoring and Reporting Program. The remainder of this document is organized as follows: 1.2 Description of Project Proposed for Approval; 1.3 Effects Determined to be Less Than Significant in the Initial Study/Notice of Preparation; 1.4 Effects Determined to be Less Than Significant in the EIR; 1.5 Effects Determined to be Mitigated to Less Than Significant Levels; 1.6 Environmental Effects Which Remain Significant and Unavoidable After Mitigation and Findings;and 1.7 Alternatives to the Proposed Project. 1.2 DESCRIPTION OF PROPOSED PROJECT The proposed project would replace the Bay Bridge Pump Station and associated force mains. The proposed project would bring the pump station facility and force mains to current design and reliability standards to ensure continuous service for the Newport Coast service area. The primary project components are described in detail below,and consist of 1)pump station improvements;2)Newport Bay Channel crossing force main improvements, and 3) West Coast Highway crossing force main improvements. Pump Station Impromments The proposed project would include construction of new pump station facilities including a pump station,generator, and odor control facilities in the northeast corner of the existing Bayside Village RV storage facility. The existing Bay Bridge Pump Station would remain in service and fully operational while the new pump station is being constructed. Once the new pump station and ancillary facilities are Statement of Facts and Findings 2 December 2017 Final Environmental Impact Report Bay Bridge Pump Station and Foxe Maine Replacement Project completed and commissioned, the existing force mains would be abandoned and the existing pump station would be taken out of service, demolished, and redeveloped with future mixed use residential and commercial development as part of the future Back Bay Landing Project. The new pump station facility would be approximately 10,000 square feet in site area,as opposed to approximately 4,800 square feet under existing conditions (an increase of 5,200 square feet). OCSD would be required to negotiate and acquire the property for use and access from the property owner (Bayside Village Marina, LLC). In addition, the new pump station would require the replacement of several portions of the existing OCSD gravity sewer system,which would be constructed to convey wastewater to the new pump station wet well. Primary access to the proposed pump station would be provided via a shared driveway from Bayside Drive through the Bayside Village Marina property, and OCSD would access the site from Bayside Drive. OCSD currently operates the pump station with two large and two smaller duty variable frequency drive(VFD)pumps. Currently,two large VFD pumps (sized at 250 horsepower [HP] each) convey full peak wet weather flows and the two smaller duty VFD pumps are 50 HP each and convey low flows. OCSD recently added a large standby pump to the existing Bay Bridge Pump Station for additional contingency during peak wet weather flow should one of the large duty pumps become disabled. Therefore, the new pump station would be sized to house all pumps and provide the desired contingency and redundancy to maintain uninterrupted service. All the facilities would be placed within a new pump station building,electrical budding,generator building,and an odor control facility. The proposed pump station building would include features, architecture, and screening consistent with the Back Bay Landing Planned Community Development Plan (PCDP) and associated design guidelines to ensure consistency with surrounding future development. In addition, modifications to the existing gravity sewer system would need to occur in order to route gravity sewage flows to the new pump station's wet well. These gravity sewer improvements would include the construction of 320 linear feet(LF) of 12-inch vitrified clay pipe (VCP)within East Coast Highway immediately west of Bayside Drive,320 LF of 36-inch VCP along Bayside Drive immediately north of East Coast Highway, and 100 LF of 42-inch VCP from Bayside Drive to the new pump station. Pump Sta bon Mechamcal Room and Wet WeR The proposed pump station budding would be constructed with a below gradedry pit;which would house the pumps,motors, and other mechanical equipment, and an above grade budding that would house the electrical instrumentation, control equipment, and restroom. An underground wet well would be constructed adjacent to the mechanical room in an orientation similar to the existing pump station. A total of five pumps would be installed to meet future peak flow of 18.5 MGD and provide required contingency/redundancy. Pump St2don Slecalcal Room The electrical room associated with the proposed pump station would be located above the below- grade dry-pit referenced above. This building would house the VFD pumps associated with the project,which would include a total of three large VFD pumps (sized at 250 HP each) and two smaller duty VFD pumps that are 50 HP each. Ancillary equipment within the electrical room would include Statement of Facts and Findings 3 December 2017 Final Environmental Impact Report Bay Bridge Pump Station and Force Mains Replacement Project electrical breakers,lighting control panel,closed-circuit television equipment,work areas, and storage space. Pump Statron Gen=torFacjhty A 620 square-foot backup generator facility would be built adjacent to the proposed pump station budding. A 750kw Caterpillar diesel backup generator would be provided to handle the power requirement of the new pump station running at full capacity. The backup generator would be paired with a 66-gallon fuel tank, which would allow the pump station to run on backup power for approximately 11 hours for operational redundancy. Pump Station Odor Control A new odor control facility would be built adjacent to the new pump station. It would hold a multi- stage vapor-phase odor control scrubber system, which would remove odorous chemicals from the incoming waste stream. The proposed project site provides space for two 10-foot diameter tanks to accommodate liquid phase odor control. NEWPORT BAY CHANNEL CROSSING FORCE MAIN IMPROVEMENTS The proposed project would include the construction of a total of 3,985 LF of dual 32-inch force mains to connect the proposed new pump station to the existing OCSD force main system west of the Newport Bay Channel. Pan of the proposed force main alignment would require a crossing of the Newport Bay Channel. In order to convey wastewater from the new pump station,the project proposes to construct 32-inch HDPE dual force mains in two separate horizontal directional drilling (HDD) bores underneath the existing Newport Bay Channel. At the new pump station site,approximately 150 LF of dual 32-inch sewer force main would be constructed in a trench between the HDD bore pit and the new pump station. The dual force mains would exit the pump station's west side,through a flow meter and valve vault,and continue west to cross under the Newport Bay Channel. The lowest point of the crossing would be at approximate-60 to -70 feet in elevation. The tunnels would be approximately 1,360 feet long and would be drilled from either side of the Newport Channel. The installation of the pipeline would occur from either side of the channel. From the side the pipe is being installed on,a continuous pipe stringer would be utilized. The stringer is the pipe that would be pulled into the tunnel and would extend along the eastern portion of Dover Drive. The location where the force mains enter Castaways Park is preferred to be on the south end. In the event it is detemtined during final design that the force mains would land on the north end, OCSD would consult with the City of Newport Beach to encumber the property as little as possible. Microtunneling may be utilized as an alternate option for construction of the force mains across the Newport Bay Channel. Microtunneling would result in a similar range of impacts in regards to construction activity,work areas, and construction duration. WEST COAST HIGHWAY FORCE MAIN IMPROVEMENTS After crossing the Newport Bay Channel,the force main alignment would head south from a disturbed area in Castaways Park to the existing OCSD force main system. Within the disturbed area in Statement of Facts and Findings 4 December 2017 Final Environmental Impact Report Bay Bridge Pump Station and Foxe Mains Replacement Project Castaways Park, the force mains would be trenched via open cut for a distance of approximately 260 LF in a westerly and southerly direction towards West Coast Highway. To avoid impacts to traffic along West Coast Highway, the force mains would be micromnneled beneath the roadway surface to extend to the existing OCSD valve vault. The microtunnel would begin within the southerly portion of the disturbed area south of Castaway Park, and would extend a distance of approximately 260 LF within two separate tunnels (each carried in a 48-inch casing) and terminate at the valve vault. If it is determined during final design that the new force mains cannot be connected to the existing valve vault, an alignment variation would traverse Dover Drive and connect to the existing force mains within the intersection of Dover Drive and West Coast Highway. CONSTRUCTION PHASING The proposed project would involve construction of the new Bay Bridge Pump Station and associated force mains. The construction of the proposed project is expected to take approximately 44 months for completion, beginning in September 2020 and ending in May 2024. Primary elements associated with construction of the proposed project are described in detail below. Pump Station Improvements As noted above,the existing Bay Bridge Pump Station would remain in service until the new facilities have been constructed and commissioned. Once the new pump station is placed in service, the existing pump station would be taken out of service and demolished. Construction access would be provided via a driveway to the property along the west side of Bayside Drive. As an ancillary facility to the pump station,the project would also include gravity sewer improvements along Bayside Drive and East Coast Highway. These gravity sewer improvements would include the construction of 320 LF of 12-inch VCP within East Coast Highway immediately west of Bayside Drive, 320 LF of 36-inch VCP along Bayside Drive immediately north of East Coast Highway, and 100 LF of 42-inch VCP from Bayside Drive to the new pump station. It is anticipated that construction along East Coast Highway would require temporary closure of the eastbound right-turn lane onto Bayside Drive. Similarly, construction along Bayside Drive (a two lane roadway, one lane in each direction) is also anticipated to require closure of one travel lane. Construction of the gravity sewer improvements is expected to take 2 to 4 weeks for completion. OCSD would be required to develop Traffic Control Plans for review and approval by Caltrans and the City of Newport Beach to ensure continuous access to surrounding routes and uses. Force Main Improvements Newport Bay Channel Crossing Force Main Improvements As noted above, the project would require force main improvements beneath the Newport Bay Channel. Construction activities for the Newport Channel Crossing are expected to take approximately 9 to 12 months from start to finish. The east work area in the Bayside Village Marina LLC property site would be approximately 80,000 square feet. This area is necessary for drilling of the HDD bore path and removal of spoils during the Statement of Facts and Findings 5 December 2017 Final Environmental Impact Report Bay Bridge Pump Station and Force Mains Replacement Project reaming process. On the west side of the Newport Bay Channel, the west work area would occur within existing disturbed City property in Castaways Park. This area would be approximately 65,000 square feet. These areas would be used for drilling equipment as well as staging for pipe. After the bore path is constructed,the pipe would be staged on Dover Drive or Bayside Drive and fused in one continuous pipe string. The pipe string staging area would include a portion of these roadways,which may require closure of one lane of northbound traffic during off-peak hours. The pipe string would extend approximately 1,200 feet north. As noted above,microtunneling maybe utilized as an alternate option for construction of the force mains across the Newport Bay Channel. Microtunneling would result in a similar range of impacts in regards to construction activity, work areas, and construction duration. West Coast Highway Force Main Improvements The West Coast Highway force main crossing is expected to require approximately 20,000 square feet of jacking shaft area within the disturbed area of Castaways Park,and approximately 10,000 square feet of reception shaft work area on the south side of West Coast Highway. This jacking shaft area north of West Coast Highway would account for excavations necessary to layout the new force mains to fit and connect up to the existing force mains south of the roadway. The existing north force main is made of HDPE and would be fused to the new force main once crossing with West Coast Highway is made. If it is determined during final design that the new force mains cannot be connected to the existing valve vault,an alignment variation would traverse Dover Drive and connect to the existing force mains within the intersection of Dover Drive and West Coast Highway. GOALS AND OBJECTIVES Pursuant to Section 15124(b) of the CEPA Guidelines, the EIR project description must include"[a] statement of objectives sought by the proposed project....The statement of objectives should include the underlying purpose of the project" The proposed project goals and objectives are as follows: 1. To accommodate anticipated growth in the region and wet weather flows,the peak wet weather flow conveyance capacity would be increased from 16 million gallons a day (MGD) to 18.5 MGD; 2. Increase reliability since the existing Bay Bridge Pump Station is approximately 52 years old, outdated, and no longer meets structural, electrical, or maintenance standards. In addition, since the existing force mains are located under the Newport Bay Channel, thorough inspection to predict the remaining life span is not possible. Thus, replacement of the force mains would reduce the risk of failure and prevent possible releases of sewage into the Newport Bay Channel; and 3. Increase safety for OCSD Operations&Maintenance personnel where safe entry and exit can be made and maintenance crews and drivers can easily access the site. The existing pump station is accessed directly from East Coast Highway, where adjacent traffic creates safety hazards for OCSD vehicles.

A description of these alternatives,a comparison of their environmental impacts to the proposed project, and the OCSD's findings are listed below. These alternatives are compared against the project relative to the identified project impacts (summarized in Section 1.4 and Section 1.51 above) to the project objectives (as stated in Section 1.2,above). In making the following alternatives findings,OCSD certifies that it has independently reviewed and considered the information on alternatives provided in the Draft EIR, including the information provided in the comments on the Draft EIR and the responses thereto. "NO PROJECT/FUTURE BACK BAY LANDING DEVELOPMENT"ALTERNATIVE Pursuant to CEQA Guidelines Section 15126.6(e)(2), the No Project Alternative must be analyzed within the EIR The No Project Alternative should discuss what would reasonably be expected to occur in the foreseeable future if the proposed project were not approved. In certain instances, the No Project Alternative means "no build" wherein the existing environmental setting is maintained. Thus,the"No Project/Future Back Bay Landing Development"Alternative includes a discussion and analysis of the existing baseline conditions at the time the Notice of Preparation was published on November 10, 2016. Findings 1. The findings of the proposed project set forth in this document and the overriding racial, economic, and other issuer set forth in the Statement of Overriding Considerations provide support for the proposed project and the elimination of this alternative from further consideration. Facts in Support ofFinchngs The"No Project/Future Back Bay Landing Development"Altemative is considered environmentally superior to the proposed project in regards to aesthetics/light and glare, air quality, biological resources,cultural resources,geology and soils,GHGs,hydrology and water quality, noise,and tribal cultural resources. However, the "No Project/Future Back Bay Landing Development" Alternative would not accomplish any of the project objectives as listed above in Section 1.2. The pump station, force mains, and gravity sewer improvements would not be constructed. As such, the pump station and conveyance facilities would not be replaced to meet current structural and maintenance standards and would not increase conveyance capacity to accommodate anticipated growth and wet weather flows. Further, the "No Project/Future Back Bay Landing Development" Alternative would not increase safety for OCSD Operations and Maintenance personnel where safe entry and exit can be made and maintenance crews and drivers can easily access the site. Statement of Facts and Findings 40 December 2017 Final Environmental Impact Report Bay Bridge Pump Station and Force Mains Replacement Project "EXISTING PUMP STATION SITE REHABILITATION"ALTERNATIVE Under the "Existing Pump Station Site Rehabilitation" Alternative, the new pump station would be constructed at and adjacent to the existing Bay Bridge Pump Station. The pump station would be expanded from approximately 4,800 square feet under existing conditions to 9,500 square feet (an increase of 4,700 square feet). Comparatively, this would be 500 square feet less than the proposed project. This Alternative would construct a new pump station building and electrical building to the west of the existing structures and would construct-in-place a new generator building and odor control facility. Access to the pump station would be provided via a driveway on the west side of Bayside Drive. A short segment(approximately 90 feet) of vitrified-clay pipe(VCP)would be constructed to connect the gravity-fed sewer system to the new pump station wet well. The dual 30-inch high-density polyethylene (HOPE) force mains would be installed under East Coast Highway via micro-tunneling. Once on the south side of East Coast Highway, the force mains would head west across property owned by The Irvine Company via trenching, cross under the Newport Bay Channel via either dredging or microtunneling on the south side of the Newport Bay Bridge, and then connect to the existing OCSD force mains to the south of West Coast Highway and west of Newport Bay Channel. For the purposes of this analysis, it is assumed that the Newport Bay Channel crossing would be constructed in similar manner to the proposed project (i.e.,microtunneling). Findings 1. The findings of the proposed project set forth in this document and the overriding racial, economic, and other issues setforih in the Statement of Overriding Considerations provide support for the proposed project and the elimination of this alternative from further consideration Facts in Support ofFindings The "Existing Pump Station Site Rehabilitation" Alternative would attain the project's objectives. As with the proposed project, the pump station and force mains would be replaced to meet current structural and maintenance standards and would increase conveyance capacity to accommodate anticipated growth and wet weather flows. Access to the pump station site would be provided via Bayside Drive under this Alternative, resulting in safety improvements for OCSD Operations and Maintenance personnel. In comparison to the proposed project,the"Existing Pump Station Site Rehabilitation"Alternative would result in reduced impacts in regard to hazards and hazardous materials and greater impacts in regard to aesthetics/light and glare. However, all of the project's objectives would be met. "PUMP STATION SOUTH RELOCATION"ALTERNATIVE The"Pump Station South Relocation"Alternative would construct a new pump station south of the East Coast Highway and east of Newport Bay Channel. The new pump station facility would require construction of a retaining wall along Newport Bay Channel to increase the buildable-space of the property. Approximately 800-feet of dual 30-inch diameter force mains would be installed via either microtunneling or dredging through Newport Bay Channel (south of Newport Bay Bridge). For the Statement of Facts and Findings 41 December 2017 Final Environmental Impact Report Bay Bridge Pump Station and Force Mains Replacement Project purposes of this analysis,it is assumed that the Newport Bay Channel crossing would be constructed in similar manner to the proposed project(i.e.,microtunneling). After crossing Newport Bay Channel, the force mains would connect to the existing OCSD force main system south of West Coast Highway. The new pump station would require the construction of a new connection to the OCSD gravity sewer system. The 42-inch VCP gravity sewer would be rnicrotunneled under East Coast Highway. After the new facilities are completed and commissioned,the existing force mains would be abandoned,the pump station would be demolished,and OCSD would construct a backup generator and odor control facility where the existing pump station is currently located. The backup generator and odor control facility would be constructed at the existing pump station site due to space constraints at the new pump station site south of East Coast Highway. Findings 1. The findings of the proposed project.set forth in this document and the overriding social, economi, and other issues set forth in the Statement of Oveniding Considerations provide.support for the proposed project and the elimination of this alternative from further consideration. Facts in Support ofFindings The"Pump Station South Relocation"Alternative would attain all of the project's objectives,including the ability to accommodate anticipated growth, meet current structural and maintenance standards, and increase safety with regard to project access. In comparison to the proposed project,the `Pump Station South Relocation"Alternative would result in reduced impacts in regard to hazards and hazardous materials and greater impacts in regard to aesthetics/light and glare, biological resources, and hydrology and water quality. However, all of the projecPs objectives would be met. 2.0 CERTIFICATION OF THE FINAL EIR OCSD declares that no new significant information as defined by the State CE,QA Guidelines,Section 15088.5, has been received by OCSD after circulation of the Draft EIR that would require recirculation. The OCSD certifies the EIR based on the following findings and conclusions: 2.1 FINDINGS The proposed project would not have the potential for creating significant adverse environmental impacts. It was determined that applicable mitigation measures would avoid or substantially lessen potential project impacts,and that no significant unavoidable impacts would occur. 2.2 CONCLUSIONS Statement of Facts and Findings 42 December 2017 Final Environmental Impact Report Bay Bridge Pump Station and Force Mains Replacement Project • All significant environmental impacts from the implementation of the proposed project have been identified in the EIR and, with implementation of the mitigation measures identified, would be mitigated to a level of insignificance. • Alternatives to the proposed project,which could potentially achieve the basic objectives of the proposed project,have been considered aid rejected in favor of the proposed project.

The Orange County Sanitation District (OCSD) has completed capital expenditures of over$500 million for transition to full secondary treatment facilities to improve the quality of our treated wastewater discharge to the Ocean as well as provide a higher quality effluent to support our partnership with the Orange County Water District in the world's largest indirect potable reuse program,the Groundwater Replenishment System. As Orange County continues to grow and evolve to a more urban environment, OCSD must grow with it to provide resilient service and enhanced resource recovery. For the past year, OCSD has been developing our 2017 Facilities Master Plan.This plan provides a comprehensive analysis of the condition and capacity of our wastewater infrastructure, including our collection system trunk sewers and pump stations,as well as our treatment facilities at both Plant No. 1 in Fountain Valley and Plant No. 2 in Huntington Beach. Understanding the condition and capacity of the existing facilities,the Master Plan assessed new technology opportunities,anticipated regulatory changes,and resource recovery options to create a roadmap of facility evaluation which supports our mission over the next 20 years. This Executive Summary provides an overview of the information obtained and generated during preparation of this Master Plan. It is a compilation of the status of OCSD's existing infrastructure as well as OCSD's future direction for adding, rehabilitating,and replacing facilities.The Master Plan provides a framework for the evolution of sustainable wastewater collection and treatment throughout Central and Northern Orange County.

A facilities master plan is a long-term planning document that addresses the wastewater collection,treatment, recycling, and ocean outfall facility needs for OCSD over a defined planning period.The major goals of this Facilities Master Plan are to identify a phased 20-year program of capital improvement projects that maintain reliability and accommodate future growth, as well as meet future regulatory requirements, level of service goals,and strategic initiatives.With this plan, OCSD can identify the capital investments needed to achieve its goals and adjust rate structures to produce the necessary cash flow. The four major drivers of this Facilities Master Plan, CONDITION CAPACITY REGULATIONS INITIATIVES Aging Infrastructure Increases in wastewater New regulations and OCSD's service goals requiring rehabilitation flow and loading requirements and strategic initiatives or replacement In this Master Plan,most of the projects identified are the result of the need to rehabilitate and replace aging infrastructure in the collection system and treatment plants. It is OCSD's charge to maintain the integrity of assets that serve as the basis for its every day operation.The identified projects prepare the facilities to operate for the next 20-30 years with asset management. r ..................................................................

I - M ...� 1 :1 • - - M - ' - - ' - 9 WHAT WE DO WITH ORANGE COUNTY WASTEWATER The wastewater treatment process treats municipal,commercial,and industrial sewage, removing contaminants before sending the water to Orange County Water District for the Groundwater Replenishment System IGWRS) for reuse or before releasing to the ocean. In 2001, OCSD's Board of Directors voted to take their operating facilities to full secondary treatment,a higher level of treatment that uses biological processes to remove up to 90 percent of organic matter from wastewater.This investment was made to ensure that high-quality water is released into the ocean and provided to the GWRS. Full secondary treatment was achieved in 2012. OCSD is a leader in water,energy,and solids resource recovery;the process of capturing specific waste materials and repurposing them into viable next use,much like municipal waste recycling and composting. For wastewater treatment,this process extends to collecting, extracting,and reusing resources in wastewater. OCSD actively engages in these cost-effective and environmentally safe recycling efforts to return pure drinking water, usable biosolids,and ' clean energy to the community. ............................................................................................................................................... STEP © PRELIMINARY TREATMENT Screening and grit removal remove larger objects and materials that clog-up ' downstream treatment processes; anything from rags and floss to coffee grounds.At this point,the water still includes biodegradable solids and dissolved organics. STEP COLLECTION r When you flush the toilet,take a shower, or drain dishwater from your sink,the wastewater goes down the drain and into a series of sewer pipes that connect to one of OCSD's - treatment plants. RESOURCES THAT ARE RECOVERED FROM THE TREATMENT PROCESS Biosolids • OCSD produces over 500 million pounds of biosolids a year,which are recycled to agricultural land or used to produce compost materials used in nurseries and landscaping.These highly treated biosolids are beneficial as soil amendments and are an environmentally friendly alternative to fossil-fuel intensive fertilizers. Water Reuse • The GWRS's high-quality water replenishes the groundwater basin. It is locally controlled and drought resilient,and costs less than imported water. It produces 100 million gallons per day of highly purified water,enough to meet the needs of 850,000 people. Energy 0 • Methane gas captured in the anaerobic digesters is used to fuel engine-generators that produce electricity and heat.This energy source powers over 60 percent of OCSD's energy needs,which saved rate payers$4.8 million dollars in energy costs in 2015-2016. In addition, this non-fossil fuel energy source offsets fossil fuel consumption and reduces OCSD's carbon footprint. 0 ............................................................................................................................................................................................................ STEP PRIMARY ADVANCED TREATMENT TREATMENT -GROUNDWATER (PHYSICAL) REPLENISHMENT SYSTEM The wastewater passes into large (ORANGE COUNTY WATER DISTRICT) settling tanks where the remaining solids sink to the bottom of the tank, lel The treated water flows to the Groundwater removing 80 percent of solids in the Replenishment System,where it undergoes a water.The resulting sludge and scum STEP state-of-the-art purification process consisting are sent to the plants digesters to of microfiltration, reverse osmosis,and ultraviolet undergo anaerobic digestion. SECONDARY TREATMENT light with hydrogen peroxide for disinfection (BIOLOGICAL) t The partially treated wastewater is sent to aeration basins or trickling filters for further treatment.Microorganisms feed on the remaining organic materials in th wastewater.Aker the microorganisms (secondary sludge) are removed,the treated water is then sent to the Groundwater Replenishment System or released into the Pacific Ocean. RESOURCE RECOVERY POINT:The RESOURCE RECOVERY POINT:Anaerobic digestion is the process Groundwater Replenishment System in which microorganisms break down and convert biodegradable generates 100 million gallons of nearly distilled materials into useful binges and biosolids.Anaerobic digestion is quality water per day.This reliable water not only cost-efficient and generative of reusable resources,but supply is used to prevent seawater intrusion can also greatly reduce the amount of organic matter that would and replenish Orange County's aquifer. otherwise need to be hauled off site for reuse. ShapeDrivers that the 2017 Facilities Master Plan OUR RESPONSE TO THE CHALLENGES AND OPPORTUNITIES WE FACE IN THE NEXT 20 YEARS GWRS Final Expansion Every day,OCSD provides up to 130 million gallons of treated wastewater to GWRS,which produces approximately 100 million gallons of purified water for residents of Orange County. In November 2016,OCWD and OCSD committed to the GWRS Final Expansion,a project that will further increase the GWRS treatment capacity to 130 million gallons per day,enough water to meet the needs of one million people.This requires OCSD to provide approximately 40 million more gallons of secondary-treated wastewater to OCWD per day.This G W R S increase will be accommodated through changes and additions to infrastructure •� that will allow treated effluent from Plant No.2 in Huntington Beach to be delivered to the GWRS treatment system in Fountain Valley. In addition,OCSD 7osres �,ke weer has committed to the collection and treatment of up to 10 VIGO of dry weather __ . r urban runoff to help protect local beaches from dry weather urban runoff contamination.This additional water source will add to the amount of water available for GWRS recovery and reuse. 3� �AO' _ ; ✓ Aging Infrastructure OCSD's capital improvement program has been evolving OCSD PROJECTED WASTEWATER FLOW over time. In the beginning,the program focused on 350 creating the initial infrastructure of the collections and 3W eR,nn treatment system.The focus then shifted to expansion 2°°9 vror of capacity and over the past ten years,OCSD's capital nso Actuaiii w 2011 Prnieca-r, improvement program has centered on improving treatment E ruac°`�°° - quality.The 2017 Facilities Master Plan wastewater flow €2. -- zov projection projections show that capacity is no longer a driving s asc (lower Bound) factor to our capital improvement program. Instead, OCSD's biggest challenge is aging infrastructure and 100 obsolescence of assets. In fact,the largest driver for the future projects identified by the 2017 Facilities Master 50 Plan is the replacement and rehabilitation of OCSD's aging 0 infrastructure and maximizing resource recovery. 1990 1995 2000 2005 2010 2015 2020 2025 2030 2035 2040 vor Biosolids Master Plan Due to aging structures and seismic risks,the digestion facilities at Plant No. 2 in Huntington Beach will need to be replaced.OCSD recently completed a Biosolids Master Plan to evaluate the biosolids markets and technology options.The plan keeps in mind OCSD's goal to accommodate Orange County's food waste diversion needs. It will serve as the road map for sustainable and cost-effective biosolids management options over a 20-year period and will diversify our biosolids portfolio. The result is a higher quality biosolids product that can be beneficially reused as fertilizer for farmland or as compost for agriculture,nurseries, and home gardens. Co-Digestion of Food Waste The State of California mandates that local jurisdictions reduce the amount ofAO organic material entering landfills by 75 percent by 2025.With the anaerobic y p digestion facilities already in place,OCSD can serve a vital role in helping the state meet its goal by receiving food waste to be co-digested with its solids to increase �! biogas production and energy. OCSD has planned to construct an interim and permanent food waste receiving facilities.The receiving facilities are planned to be located at Plant No. 2 in Huntington Beach. Co-digestion at OCSD is an important step towards energy self-sufficiency from increased gas production,which meets C ,� OCSD's energy policy goals. MPOS LONG-TERM PLANNING NEEDS Beyond the 20-year planning addressed in this 2017 Facilities Master Plan,additional existing facilities will eventually require replacement.The existing treatment plant sites are or will be nearly fully utilized and future replacement of major processes while maintaining the services they provide will be challenging. Many non- process facilities can potentially be located at newly acquired off-site properties,freeing up treatment plant land for long-term process replacement.This,along with other long-term options for land use planning,will need to be evaluated in greater depth in future studies. IMPROVEMENTS TO MAINTAIN THE INTEGRITY OF OUR REGIONAL TRUNK SEWER SYSTEM AND PUMP STATIONS R OCSD's 479-square-mile service area is divided into 11 sewer sheds.The trunk '. sewer system consists of approximately 396 miles of gravity pipelines,and force mains,and numerous access and flow diversion structures.The majority �'• of the system operates by gravity flow; however, 15 off-site pump stations are necessary to lift the wastewater at various locations throughout the service area. The majority of the pipelines were originally constructed between 1950 and 1979, making them up to 67-years-old,and pump stations up to 60-years-old.

O Our Capital Improvement • • WHAT OUR PROJECTS WILL COST PROJECTED ANNUAL CIP OUTLAY The projects identified in the master planning process were incorporated into the existing 10-Year Total: 20-Year Total: Capital Improvement Program (CIP).This program $2,451,000,000 $5,023,000,000 identifies an implementation schedule for each project and develops annual expenditures required over the 20-year planning period to implement the projects.The projects are scheduled based on a prioritization process that takes into account facility condition, evaluation of remaining useful life, criticality of the facility, avoidance of implementation conflicts,and cash flow and resource constraints. The Master Plan provides a listing of all newly HII ,o identified projects,including justification for the x = project, project description,cost estimate,and recommendation for implementation timing.The 20-year CIP which includes existing projects authorized by the Board of Directors and projects identified in this Master FUTURE PROJECTS IDENTIFIED THROUGH Plan totals$5 Billion,and averages approximately$250 Million per year. MASTER PLANNING PROCESS HOW WILL THE PROJECTS BE PAID FOR PUMP Sewer system user fees and connection fees are collected to pay down STATIONS 6% prior project debt,fund capital improvements,and pay for system SEWER PLANT 26% operation and maintenance costs. User fees are charged based on PIPES 13% No.t the quantity and strength of wastewater discharged by various user categories.These user fees are collected on the County-wide annual property tax bill.Connection fees are charged when new customers are added to the system to recover the cost for capacity to serve new users. JOINT OCSD currently carries a balance of approximately one billion dollars FACILITIES 12% of debt for the previous projects including the construction that was required to achieve full secondary treatment.This debt is paid down over time, similar to a home mortgage.The CIP identified in this Master Plan will not require OCSD to take on additional debt. Projects have been planned for implementation based on projected availability of funds collected from the user and connection fees. PLANT 43% WILL OUR RATES CHANGE Na 2 The cost of wastewater treatment is subject to inflation and experiences cost increases with time,similar to other goods and services,mainly due to increased cost of electricity,treatment chemicals, labor,and raw materials for new construction. Most utilities experience a nominal increase every few years that reflects these increased costs. User rates and connection fees already include an amount for expected future capital expenditures. It is anticipated that customers will not experience a rate increase that is substantially different than the normal annual inflationary rate change.

As projects identified in this Master Plan approach the time for implementation,they will be brought to the OCSD Board of Directors for approval as part of the annual budget update process.The management of these projects is a large endeavor that will require the participation and support from staff throughout the agency. OCSD is committed to providing reliable,high-quality wastewater collection,treatment and beneficial reuse to Orange County's residents,while implementing sustainable, cost-effective practices that benefit our community and the environment. OCSD's asset management program allows us to operate and maintain our assets to deliver the required level of service in the most cost-effective manner. Efforts from all departments are well planned, clearly communicated and closely coordinated. These asset management efforts include operations,planned maintenance, corrective maintenance, condition assessments and capital improvements projects such as those identified in this Master Plan. Finally,we must continually plan for the future by routinely evaluating our facilities' conditions and capabilities and measuring them against future demands and regulatory _ requirements.We will update this Master Plan regularly to ensure OCSD continues to _ provide a reliable and necessary service to our rate payers well into the future. 1 i
