Document Description
The California Department of Toxic Substances Control (DTSC) is proposing approval of the Record of Decision (ROD)/Remedial Action Plan (RAP) for the former Mare Island Naval Shipyard IA F1. The proposed action consists of excavation, removal, and off-site disposal of 1,250 cubic yards of lead-contaminated soil from upland areas, as well as dredging, removal, and off-site disposal of 3,600 cubic yards of metals contaminated wetland sediment. Clean soil and sediment will be imported and placed in the excavated areas as part of site restoration. The upland areas, referred to as Subarea 4 and Subarea 5 will remain clear after the project is complete to provide a wildland fire control break and be available for possible future reuse. A small portion of Subarea 6, will be replanted with similar vegetative types and quantities as currently found on the site. The excavation within a wetland (a majority of Subarea 6) will be backfilled with imported sediment and the wetland, including wetland vegetation, will be restored to its current condition. The project will be scheduled for a time of the year (April through October) when rainfall is unlikely. The Department of Defense derives authority to undertake this cleanup action under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) under 42 United States Code U.S.C. Section 9604, 10 U.S.C. Section 2705. DTSC is proposing to approve this project pursuant to the authority granted under Chapter 6.8, Division 20, California Health and Safety Code (H&SC). Investigation Area F1 includes 28 buildings and is partially paved with numerous paved lots and roads. Other areas include landscaping vegetation, natural vegetation, and a tidally influenced wetland. Investigation Area F1 is approximately 62 acres in size and located in the southeastern portion of Mare Island at the approximate southeastern intersection of Price Way and Railroad Avenue.
