Document Description
The California Department of Toxic Substances Control (DTSC) adopted an Addendum to the previous Environmental Impact Report and approved the renewal of the Post Closure Permit (Permit) for West Contra Costa Sanitary Landfill (Facility), pursuant to California Health and Safety Code, Chapter 6.5. The Facility area covers about 28-acres located in Richmond, California and includes several units. The units include (1) a capped, closed Class I Hazardous Waste Landfill, identified as the Hazardous Waste Management Facility (HWMF), (2) a Leachate Treatment System (LTS), located south of the HWMF, (3) a Corrective Action Management Unit (CAMU), which receives solid hazardous waste generated from the LTS process, and (4) an area undergoing corrective action monitoring known as the E-22R area, located east of the HWMF. The Permit authorizes the Facility to continue the following post closure activities for another ten years: 1) regular inspection and maintenance of the cover and drainage systems (with corrective action as necessary); 2) environmental monitoring, consisting of regular monitoring well inspection, sampling, and data analysis; and 3) maintenance of financial mechanisms to fund the post closure activities. No physical changes to the site are proposed in this Permit and the Facility area has been in post closure detection and corrective action monitoring since December 1991. As Lead Agency under the California Environmental Quality Act (CEQA), DTSC approved the above-described project on May 26, 2022 and has made the following determinations: 1. The project will not have a significant effect on the environment. 2. An Environmental Impact Report was prepared for this project pursuant to the provisions of CEQA. 3. Mitigation measures were not made a condition of project approval. 4. A Statement of Overriding Considerations was not adopted for this project. 5. Findings were not made pursuant to the provisions of CEQA.
