And, A Street and Bitter Point Pump Stations, located in the City of Newport Beach will require construction of two, above-grade pump stations at new locations to replace the existing structures; and, WHEREAS, District is the Lead Agency for the preparation and-consideration of environmental documents for the Final Initial Study/Mitigated Negative Declaration for the Projects, which are consistent with the 1999 Strategic Plan Program Environmental Impact Report and the Supplemental Environment Impact Report for the Effluent Pump Station Annex and Collection System Odor Control Program, dated November 2002, pursuant to the California Environmental Quality Act of 1970, as amended ("CEQA"), the State of California CEQA Guidelines, and District's CEQA procedures; and, WHEREAS, to assess the Rehabilitation of the Edinger Pump Station, Rehabilitation of the A Street Pump Station, and Replacement of the Bitter Point Pump Station environmental impacts objectively, District prepared an Initial Study/Mitigated Negative Declaration to assess the potentially-significant environmental impacts, mitigation measures, if any, and alternatives associated with the Projects; and, 1 WHEREAS, in accordance with CEQA Guidelines 15070, District staff determined that an Initial Study/Mitigated Negative Declaration resulted in a determination that there were only less than significant impacts associated with the proposed Projects if certain mitigation measures were implemented, therefore an Initial Study/Mitigated Negative Declaration was prepar~d; and, WHEREAS, District has consulted with other public agencies and the general public, giving them an opportunity to comment on the Initial Study/Mitigated Negative Declaration, as required by CEQA; and, WHEREAS, District has objectively evaluated, received, and filed comments from public agencies and persons who reviewed the Initial Study/Mitigated Negative Declaration; and, WHEREAS, the comments and recommendations received on the Initial Study/Mitigated Negative Declaration, either in full or in summary, to significant environmental concerns raised in the review, have been included in the Final Initial Study/Mitigated Negative Declaration; and, WHEREAS, District staff presented to the Board the Final Initial Study/Mitigated Negative Declaration for review and consideration prior to the final approval of, and commitment to, the Final Initial Study/Mitigated Negative Declaration for the Rehabilitation of the Edinger Pump Station, Rehabilitation of the A Street Pump Station, and Replacement of the Bitter Point Pump Station; and, WHEREAS, District has prepared a Mitigation Monitoring and Reporting Program, designed to ensure that the approved mitigation measures are implemented during the Projects' design, construction, and operation. NOW, THEREFORE, the Board of Directors of Orange County Sanitation District, DOES HEREBY RESOLVE, DETERMINE, AND ORDER: Section 1: That changes or alterations have been required in, or incorporated into, the proposed Projects, before the proposed Initial Study/Mitigated Negative Declaration was released for public review, which avoid or mitigate significant environmental effects or substantially lessen the significant effects of the pump station "Projects" identified in the Final Initial Study/Mitigated Negative Declaration; and, Section 2: That there is no substantial evidence that the "Projects" will have a significant impact on the environment; and, Section 3: That the Final Initial Study/Mitigated Negative Declaration reflects the District's independent judgment and analysis; and, Section 4: That the documents and other materials that constitute the record of proceedings upon which the District's decision is based are located at the 2 Orange County Sanitation District, 10844 Ellis Avenue, Fountain Valley, California, 92708. The Custodian of these documents and other materials is the Board Secretary; and, Section 5: That the Board of Directors adopts the Final Initial Study/Mitigated Negative Declaration; and, Section 6: The District will implement the mitigation measures recommended in the Initial Study/Mitigated Negative Declaration to reduce the significant impacts of the project to a less than significant level; and, Section 7: The Board of Directors approves the mitigation measures, and adopts the Mitigation Monitoring and Reporting Program as described in Attachment A to ensure that all mitigation measures are implemented; and, Section 8: The Board of Directors hereby approves the following Projects: Rehabilitation of Edinger Pump Station, Contract No. 11-28; Rehabilitation of A Street Pump Station, Contract No. 5-52; and Replacement of Bitter Point Pump Station, Contract No.5-49; and, Section 9: The Board of Directors authorizes and directs the Board Secretary to file the Notice of Determination and any other documents in accordance with the requirements of CEQA and the District's CEQA Procedures; and, Section 1 O: The initial study prepared for the project evaluated the potential for adverse environmental impact. Considering the record as a whole, there is no evidence before the District that the proposed project will have the potential for an adverse effect on wildlife resources or the habitat on which wildlife depends. The presumption of adverse effect set forth in 14 California Code of Regulations §753.5(d) does not apply. PASSED AND ADOPTED at a regular meeting held March 26, 2003.
