PURPOSE AND CONTENT OF THE FINAL EIR The Department of Toxic Substances Control (DTSC), as the Lead Agency under the California Environmental Quality Act (“CEQA”), has prepared this Final Environmental Impact Report (“Final EIR”) for the Remedial Action Plan (RAP) (also referred to as the “Project”) for the Ascon Landfill Site (Site). This document, in conjunction with the Draft EIR and Recirculated Draft EIR (REIR), collectively comprise the Final EIR. As described in Sections 15089, 15090 and 15132 of the CEQA Guidelines, the Lead Agency must prepare and consider the information contained in a Final EIR before approving a project. Pursuant to CEQA Guidelines Section 15132, a Final EIR consists of: a) the Draft EIR or a revision of the Draft; b) comments and recommendations received on the Draft EIR either verbatim or in summary; c) a list of persons, organizations, and public agencies commenting on the Draft EIR; d) the responses of the Lead Agency to significant environmental points raised in the review and consultation process; and e) any other information added by the Lead Agency. In addition, this Final EIR includes: an overview of the purpose and focus of the EIR being prepared for the proposed RAP); a summary of the RAP being proposed; a description of the EIR and REIR process conducted for the Project; and a description of the contents and organization of the Draft EIR, REIR and Final EIR. Accordingly, this Final EIR is comprised of three components as follows: Component 1: Draft EIR and Technical Appendices (August 2013) Volume I: Draft Environmental Impact Report ‐ EIR Chapters 1.0 to 8.0 and Appendix A Volume II: Draft Environmental Impact Report – Appendices B through D Volume III: Draft Environmental Impact Report – Appendices E through F Volume IV: Draft Environmental Impact Report – Appendices G through I Component 2: Recirculated Draft EIR (October 2014) Component 3: Final EIR and Technical Appendices (described in more detail below) As permitted in Section 15150 of the CEQA Guidelines, both the Draft EIR and REIR have referenced technical studies, analyses, and reports. Information from the referenced documents has been briefly summarized in the appropriate section(s) of both the Draft EIR and REIR. All documents referenced in both the Draft EIR and REIR are hereby incorporated by reference and are available for public inspection and review upon request to DTSC. A summary list of the contents of the Draft EIR and REIR is provided at the end of this chapter. This Final EIR comprises the final component of the CEQA environmental review process for the proposed RAP at the Ascon Landfill Site. The Final EIR, together with the Draft EIR published in August 2013 and REIR published in October 2014, address the potential environmental impacts of the Project pursuant to CEQA, Department of Toxic Substances Control RAP EIR ‐ Ascon Landfill Site PCR Services Corporation 1‐1 1.0 Introduction May 2015 Public Resources Code Section 21000 et seq., and the CEQA Guidelines, Title 14 of the Code of California Regulation (CCR), Section 15000 et seq. The purpose of the EIR is to inform decision‐makers and the general public of the potential environmental impacts resulting from the Project. The EIR is a Project EIR as defined by Sections 15161 and 15362 of the State CEQA Guidelines. DTSC has the principal responsibility for approving the Project and, as the Lead Agency, is responsible for the preparation and distribution of this Final EIR pursuant to CEQA Statute Section 21067. The EIR will be used in connection with all other permits and all other approvals necessary for the implementation of the Project. The EIR will be used by DTSC and other responsible public agencies that must approve activities undertaken with respect to the Project. 2. PROJECT SUMMARY Background and Purpose of the RAP The RAP describes the proposed remediation plan for the Site located at 21641 Magnolia Street in Huntington Beach, California. The Site operated as a waste disposal facility from approximately 1938 through 1984, receiving at times what is now considered hazardous waste. Since 1984, waste materials have not been accepted, and the Site has remained a closed landfill facility. In 2003, DTSC entered into an Imminent and Substantial Endangerment Determination and Consent Order (I&SE CO), Docket No. I&SE CO 02/03‐007, and an Imminent and Substantial Endangerment Determination and Order and Remedial Action Order (I&SE‐RAO), Docket No. I&SE‐RAO 02/03‐018, with ten Responsible Parties (RPs).1 As a result of these agreements, the RPs are required to finance the implementation of the remediation activities at the Site. Over the past approximately 30 years, there have been numerous and extensive investigations (e.g., waste and soil characterizations, hydrogeological assessments, biological assessments, health risk assessments, groundwater contamination assessments, air quality sampling, etc.) conducted at the Site, which have led up to preparation of the RAP. Of particular relevance, these investigations have included several Remedial Investigations (RI) to define the nature and extent of waste materials and Site conditions; two Baseline Health Risk Assessments (BHRA)2 to evaluate potential human health risks associated with the Site; and a (Year 2000) Feasibility Study (FS)3 and (Year 2007) Revised Feasibility Study (RFS)4 to evaluate several remedial action alternatives for the Site and present the rationale for selecting a preferred alternative. The RFS was prepared as defined by, and in conformance with, the I&SE CO, the I&SE‐RAO, and the requirements set forth in Division 20 of the California Health and Safety Code, and Title 40 of the Code of Federal Regulations. All of the above references studies are described in further detail in the Draft EIR. 1 The ten RPs are Chevron U.S.A. Inc., Texaco Inc. (Chevron U.S.A Inc. and Texaco Inc. are now considered a single party as they are wholly‐owned subsidiaries of Chevron Corp.), Conoco Inc., Phillips Petroleum Company (Conoco Inc. and Phillips Petroleum Company are now combined as ConocoPhillips Company), ExxonMobil Corp., Shell Oil Company, Atlantic Richfield Company (ARC), The Dow Chemical Company, TRW (now Northrop Grumman Systems Corporation), and Southern California Edison Company. Two of the RPs, Chevron and ConocoPhillips, created a limited liability corporation called Cannery Hamilton Properties, LLC (“CHP”) to purchase the Site, and CHP is the current Site owner. 2 BHRA, 1997; Geosyntec, Groundwater Remedial Investigation Report (Revision 1.0)–June 14, 2007.

Department of Toxic Substances Control RAP EIR ‐ Ascon Landfill Site PCR Services Corporation 1‐2 May 2015 1.0 Introduction Since 2001, the RPs have worked with DTSC to collect additional data, conduct evaluation activities, and to complete the soil/waste RAP for the Site based on the then‐existing preferred alternative from the initial FS of 2001. The 2007 RFS reflects additional information and data obtained during the implementation of the environmental evaluations and activities after approval of the initial FS in 2000. The RFS reevaluated previously considered remedial action alternatives based on the new data and current practices in hazardous waste remediation, and evaluated additional remedial alternatives that had not been considered previously. The RFS identified and evaluated
