In the Statement of Facts and Findings, the Lead Agency identifies a project's significant impacts, presents facts supporting the conclusions reached in the analysis,makes findings for each impact,and explains the reasoning behind the agency's findings. CEQA Guidelines Section 15091 (a) provides that: No public agency shall approve or carry out a project for which an EIR has been certified which identifies one or more 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. There are three possible findings pursuant to Section 15091 (a) of the CEQA Guidelines. (1) Changes or alterations have been required in, or incorporated into, the project which avoid or substantially lessen the significant environmental effect as identified in the final EIR. (2) Such changes or alterations are within the responsibility andjurisdiction of another public agency and not the agency making the finding. Such changes have been adopted by such other agency or can and should be adopted by such other agency. (3) Specific economic,legal,social, technological, or other considerations, including provision of employment opportunities for highly trained workers,make infeasible the mitigation measures orpr iect alternatives identified in the final EIR. Where a project will cause unavoidable significant impacts,the Lead Agency may still approve a project where its benefits outweigh the adverse impacts. As provided in the Statement of Overriding Considerations, the Lead Agency sets forth specific reasoning by which benefits are balanced against effects, and approves the project. It is important to note that the Bay Bridge Pump Station and Force Mains Replacement Pr iect Public Review Draft 2020 Recirculated Environmental Impact Report (2020 Recirculated EIR) and Bay Bridge Pump Station and Force Mains Replacement Pr elect Final Environmental Impact Report (Final EIR) (together referenced herein as the EIR)prepared for the proposed Bay Bridge Pump Station and Force Mains Replacement Project determined that no significant, unavoidable impacts would occur as a result of Project implementation. Thus,while the preparation of a Statement of Facts and Findings is not mandatory under CEQA, it has been prepared by the Orange County Sanitation District (OCSD) as a means of further documenting impacts determined to be less than significant or less than significant upon incorporation of mitigation. Based upon a review of the EIR, OCSD finds that the EIR: (a) has assessed the potentially significant environmental impacts of the Proposed Project in compliance with CEQA; (b) represents the independent judgment of OCSD; and (c) sets forth an adequate range of alternatives to this Project. 1549939.1 OC SAN 21-03-9 SNrN 40�N �4 Final Environmental Impact Report 0 Bay Bridge Pump Station and Force Mains Replacement Project N N V OCSD, the CEQA Lead Agency, finds and declares that the proposed Bay Bridge Pump Station and Force Mains Replacement Project EIR (State Clearinghouse [SCH] No. 201611103) has been completed in compliance with CEQA and the CEQA Guidelines. The Final EIR is composed of the following elements: • The Bay Bridge Pump Station and Force Mains Replacement Project Public Review Draft 2020 Recirculated Environmental Impact Report (August 2020); • Responses to Comments; • Errata; 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 or Not 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 Project would replace the existing Bay Bridge Pump Station and associated force mains to bring the pump station facility and force mains to current design and reliability standards to ensure continuous service for the Newport Coast service area ("Proposed Project")'. Development of the Proposed Project would involve expanding the existing pump station facility site approximately 100 feet to the west, constructing a new pump station building, and installing force main improvements across the Newport Bay Channel south of Bay Bridge;refer to 2020 Recirculated EIR Exhibit 3-4, Proposed Conceptual Site Plan. As shown on 2020 Recirculated EIR Exhibit 3-4, the total area of potential disturbance proposed for the Proposed Project (yellow Project boundary) is approximately 800,000 square feet (18 acres). PUMP STATION The Proposed Project would involve demolishing the existing pump station building and constructing new pump station facilities including a pump station,generator, and odor control facilities within and adjacent to the existing facility; refer to 2020 Recirculated EIR Exhibit 3-5, Adiacent Pumt) Station Layout. The new, expanded pump station facility would be approximately 14,500 square feet in site 1 The Proposed Project is referred to as the"Adjacent Pump Station"in the EIR. 1549939.1 OC SAN 21-03-10 � SNrN 40�N �4 Final Environmental Impact Report 0 Bay Bridge Pump Station and Force Mains Replacement Project F area, as opposed to approximately 4,800 square feet under existing conditions (an increase of approximately 9,700 square feet). OCSD would be required to negotiate and acquire the adjacent property for use and access from the property owner (Bayside Village Marina, LLC). It should be noted that OCSD has assumed a proposed square footage of 14,500 square feet in order to analyze a conservative scenario in this 2020 Recirculated EIR. This square footage is considered conceptual and may be subject to downward refinement during final design. In addition, the new pump station would require the replacement of portions of the existing OCSD gravity sewer system,which would be constructed to convey wastewater to the new pump station wet well. These gravity sewer improvements include installing 50 linear feet (LF) of 36- or 42-inch sewer lines within East Coast Highway and OCSD property. Primary access to the proposed pump station would be provided via a shared driveway from Bayside Drive through Bayside Village Marina,LLC property with secondary access via the existing driveway from East Coast Highway;refer to 2020 Recirculated EIR Exhibit 3-5. The existing pump station has three large and two smaller duty variable frequency drive(VFD)pumps. Currently, two of the large VFD pumps (sized at 250 horsepower [HP] each) convey full peak wet weather flows and one of the smaller duty VFD pumps (50 HP each) conveys low flows. OCSD recently added the third large standby pump to the existing pump station for additional redundancy during peak wet weather flow. 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 the new pump station, including a new pump station building with an electrical room and a generator building with an odor control facility. The proposed pump station 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. Pump Station Mechanical Room and Wet Well The proposed pump station building would be constructed with a below-grade dry-pit mechanical room,which would house the pumps, motors, and other mechanical equipment, and an above grade building that would house the electrical equipment, 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 VFD pumps would be installed to meet existing peak flow of 18.2 million gallons per day (MGD) and provide required contingency/redundancy, similar to the existing pump station. Pump Station Electrical Room The electrical room associated with the proposed pump station would be located above the mechanical room referenced above. Ancillary equipment within the electrical room would include electrical breakers,lighting control panel, closed-circuit television equipment,work areas, and storage space. Pump Station Generator Facility A 760-square foot backup generator facility would be built adjacent to the proposed pump station building. A 750-kilowatt diesel backup generator would be provided to handle the power requirement 1549939.1 OC SAN 21-03-11 SNrN 40�N �4 Final Environmental Impact Report 0 Bay Bridge Pump Station and Force Mains Replacement Project F of the new pump station running at full capacity should Sothern California Edison power go down. The backup generator would have a two-hour day tank and be paired with a fuel tank which would allow the pump station to run on backup power for approximately 24 hours of operational redundancy. Pump Station Odor Control A new 1,300-square foot odor control facility would be built adjacent to the new pump station within the same building as the generator facility. It would hold a multi-stage vapor-phase odor control scrubber system,which would remove odorous compounds from the incoming waste stream. Two 10-foot diameter tanks would accommodate liquid phase odor control. Anticipated chemicals to be utilized and/or stored at the odor control facility include bioxide, magnesium hydroxide, ferric chloride, and/or pure oxygen; however,it is acknowledged that the specific chemicals used for odor control purposes may change depending on the availability of technologies at a given time, such as other chemicals with potentially increased effectiveness,and compliance with Federal,State,and local laws and regulations for the handling/storage/use of such hazardous materials, such as restrictions on which chemicals may be transported on local or regional roadways. FORCE MAIN IMPROVEMENTS The Proposed Project would connect to the existing OCSD force main system to the west by installing 1,500 LF of dual force mains (up to 32 inches in diameter) across the Newport Bay Channel south of Bay Bridge. The Project would involve microtunneling or open trench cutting under East Coast Highway, to the southside of the bridge,where dredging would occur under Newport Bay Channel. Dredging involves placement of a dredge (boat)with a submersible pump to suction out sediments at the bottom of the Newport Bay Channel. Microtunneling is a remote-controlled, continuously supported pipe jacking method. Microtunneling operations are managed by an operator in an above ground control container alongside of the shaft. Soil excavation takes place by way of infusing the soil with slurry at the face of the bore and cuttings are forced into slurry inlet holes in the Microtunneling Bore Machines crushing cone for circulation to and from a separation plant through a closed system. Areas where the pipe is microtunneled may require a casing pipe as large as 72 inches in diameter,which has been evaluated throughout this EIR as a worst-case scenario. Portions of the adjacent private property (currently a RV storage area) and Lower Castaways Park could be temporarily utilized for construction staging,if these areas are available during construction of the Proposed Project;refer to Construction,below. ACCESS, EASEMENTS,AND PROPERTY ACQUISITION Development of the Proposed Project would require approval of easements, permits, and property acquisitions potentially including,but not limited to: City of Newport Beach • Temporary easement for potential construction staging at Lower Castaways Park; Caltrans 1549939.1 OC SAN 21-03-12 � SNrN 40�N �4 Final Environmental Impact Report o Bay Bridge Pump Station and Force Mains Replacement Project F • Encroachment permit for construction activities occurring on Coast Highway; Bayside Village Marina,LLC • Fee acquisition for the new pump station site; • Temporary and permanent easement for construction and operational access to the Project site; The Irvine Company • Temporary and permanent easement for construction and operational access to proposed force mains; and Bay Shores Community Association • Temporary and permanent easement for construction and operational access to proposed pipelines on the west side of the Newport Bay Channel. CONSTRUCTION Construction activities associated with the Proposed Project, including pump station improvements, gravity sewer improvements, and force main installation (via open trenching and/or microtunneling and dredging),would encompass work areas on both sides of the Newport Bay Channel as illustrated on 2020 Recirculated EIR Exhibit 3-6,AdiacentPumb Station Work Areas. Construction activities would occur during weekdays (between 7:00 a.m. and 6:30 p.m.) and Saturdays (between 8:00 a.m. and 6:00 p.m.), unless otherwise directed by the City of Newport Beach (pursuant to City Municipal Code Section 10.28.040(D)(2)). However, it is acknowledged that due to the nature of microtunneling installation,microtunneling is anticipated and assumed to occur 24 hours per day;As explained in the EIR,it would take approximately two months to microtunnel across East Coast Highway. Pump Station The Proposed Project improvements would require approximately 4,200 cubic yards of cut and 700 cubic yards of fill. As noted above,the existing pump station facility 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. Any temporary construction access through private property would be negotiated between OCSD and the property owner. In addition, modifications to the existing gravity sewer system would be required to route gravity sewage flows to the new pump station's wet well. These pipes would be installed via open trench excavation along East Coast Highway; refer to 2020 Recirculated EIR Exhibit 3-7, Adiacent Pum�J Station Construction. Force Main Improvements 1549939.1 OC SAN 21-03-13 SNrN 40�N �4 Final Environmental Impact Report 0 Bay Bridge Pump Station and Force Mains Replacement Project F The Proposed Project's force main improvements across East Coast Highway would require either microtunneling beneath the roadway or open cut trenching approximately 150 linear feet across the roadway as shown on 2020 Recirculated EIR Exhibit 3-7. The force mains would then be installed across the Newport Bay Channel via dredging,possibly with a coffer dam. This construction method would require trenching approximately 700 feet long by 15 feet wide by 18 feet deep across the Newport Bay Channel. Trenching would occur in two segments across the channel, a 400-foot segment and a 300-foot segment. Each segment would be drained then trenched. Shoring of the walls may be required to lay down the dual force mains. Dredging would require approximately 4,450 cubic yards of cut and 3,870 cubic yards of fill. These construction activities would take approximately six months. Temporary Lane Closures Construction of the Proposed Project would require the following temporary lane closures: • East Coast Higbwa : Temporary closure of traffic lane(s) to allow for construction of the gravity sewer improvements and installation of force mains (if microtunneling is not used) for approximately 131 non-consecutive days over the Project's 36-month construction period. A minimum of one travel lane in each direction would remain open at all times. • West Coast Highway: Temporary closure of one eastbound lane of traffic and bus turnout area to allow for connection of the two force mains to the existing system for approximately 33 consecutive days during the Project's 36-month construction period. OCSD would be required to develop a Traffic Control Plan for review and approval by Caltrans and the City of Newport Beach,respectively,to ensure continuous access to surrounding routes and uses. GOALS AND OBJECTIVES Pursuant to Section 15124(b) of the CEQA 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." As noted above, the Bay Bridge Pump Station is critical to OCSD operations as it conveys approximately 50 to 60 percent of the total Newport Beach wastewater flow through the pump station and these force mains. Because the Bay Bridge Pump Station and associated force mains are critical elements to OCSD's Newport Coast collection backbone,it is imperative that the facility be upgraded to ensure continuous service to the community and avoid spills for the next design lifespan (an additional 50 years). The Proposed Project's goals and objectives are as follows: 1. Increase reliability since the existing Bay Bridge Pump Station is over 50 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; 1549939.1 OC SAN 21-03-14 SNrN 40�N �4 Final Environmental Impact Report o Bay Bridge Pump Station and Force Mains Replacement Project F p HE V 2. Increase safety for OCSD Operations &Maintenance personnel by selecting an entry to and exit from the site that can be accessed more easily and safely by maintenance crews and drivers. The existing pump station is accessed directly from East Coast Highway,where adjacent traffic creates safety hazards for OCSD vehicles. Maintenance trucks must currently back into oncoming traffic to exit the site; and 3. Improve odor control through a new odor control facility,which houses a vapor-phase odor control scrubber system that would remove odorous vapors from the incoming waste system as well as two 10-foot diameter tanks to accommodate liquid phase odor control. PERMITS AND APPROVALS The applicable agency approvals and related environmental review/consultation requirements associated with the Proposed Project may include the following, among others. It is not anticipated that any other agencies would require use of the EIR in their decision-making process. • CEQA Clearance—OCSD; • Site Development Review Permit—City of Newport Beach; • Limited Term Permit—City of Newport Beach; • Encroachment Permits—City of Newport Beach and Caltrans; • Permanent/Temporary Easements — City of Newport Beach, Bayside Village Marina, LLC, The Irvine Company, and Bay Shores Community Association; • Traffic Control Plan Approval—City of Newport Beach and Caltrans; • Coastal Development Permit — California Coastal Commission and City of Newport Beach (as required under the California Coastal Act,Public Resources Code Division 20); • California State Lands Commission — Consultation with the County of Orange regarding implementation of Newport Bay Channel force main crossing through tidelands and submerged lands; • California Department of Fish and Wildlife — Consultation regarding implementation of Newport Bay Channel force main crossing; • National Marine Fisheries Service—Dry dredging/shoring construction activities; • Section 404 Permit — Army Corps of Engineers (required for dry dredging/shoring construction activities); • Section 401 Permit — Santa Ana Regional Water Quality Control Board (required for dry dredging/shoring construction activities); • Permit R8-2015-0004—Santa Ana Regional Water Quality Control Board; • General Construction Permit—Santa Ana Regional Water Quality Control Board (as required under National Pollutant Discharge Elimination System [NPDES] General Permit for Storm Water Discharges Associated with Construction and Land Disturbance Activities (Order No. 1549939.1 OC SAN 21-03-15 � SNrN 40�N �4 Final Environmental Impact Report 0 Bay Bridge Pump Station and Force Mains Replacement Project F p HE V 2009-0009-DWQ [as amended by 2010-0014-DWQ and 2012-006-DWQ], NPDES Number CAS000002); and • Permit to Construct (P/C) and Permit to Operate (P/O) — South Coast Air Quality Management District. 1.3 EFFECTS DETERMINED TO BE LESS THAN SIGNIFICANT IN THE INITIAL STUDY/NOTICE OF PREPARATION OCSD prepared an Initial Study/Notice of Preparation for the Proposed Project to determine potentially significant effects of the Proposed Project. The Initial Study/Notice of Preparation was circulated for public review from November 10, 2016 through December 9, 2016. In the course of this evaluation, certain impacts of the Proposed Project were found to be less than significant due to the inability of a project of this scope to create such impacts or the absence of project characteristics producing effects of this type. The following effects were determined not to be significant, and were not analyzed in the 2020 Recirculated EIR;refer to U12endix 11.1,Initial Study/Notice of Preparation and Comment Letters of the 2020 Recirculated EIR. As such, the Project would not result in significant impacts involving the following: AGRICULTURE AND FOREST RESOURCES Convert Prime Farmland, Unique Farmland, or Farmland of Statewide Importance(Farmland), as shown on the maps prepared pursuant to the Farmland Mapping and Monitoring Program of the California Resources Agency, to non-agricultural use. Conflict with existing honing for agricultural use, or a Williamson Act contract.
