Document Description
Preparation and DTSC approval of the Investigation Area B.1 Feasibility Study/Remedial Action Plan (FS/RAP) is pursuant to the requirements of the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended by the Superfund Amendments and Reauthorization Act of 1986; the National Oil and Hazardous Substances Pollution Contingency Plan in Title 40 of the Code of Federal Regulations Part 300; and Chapter 6.8, Division 20, California Helath & Safety Code. The FS/RAP will address contamination at a 6 acre portion of IA B at the former Mare Island Naval Shipyard. The area is referred to as IA B.1 or the Crane Test Area (CTA) and is part of a larger parcel transferred from the Navy to Lennar Mare Island, LLC (LMI). The FS/RAP presents an evaluation of the 1925 1942 fill material within the Eastern Transfer Parcel (EETP) at the former Mare island Naval Shipyard and recommends an action based on this evaluation. this FS/RAP presents the proposed remedy to mitigate the potential risk posed by elevated concentrations of arsenic, lead, polynuclear aromatic hydrocarbons, total petroleum hydrocarbons, and polychlorinated biphenyls in surface and subsurface soils, gorundwater, and soil vapor while meeting applicable or relevant and appropriate requirements (CH2M HILL 2009).
