treasure island naval station-hunters point annex


The Hunters Point Naval Shipyard (also known as the Treasure Island Naval Station-Hunters Point Annex) is located in southeastern San Francisco, California, adjacent to San Francisco Bay in the Bayview-Hunters Point neighborhood. The Shipyard consists of 866 acres, 420 acres on land and 446 acres under water in San Francisco Bay. To better organize the investigation and cleanup, as well as to facilitate future reuse, the Shipyard has been divided into several parcels. Site History: Prior to European settlement of California, historians estimate that seven to ten thousand Native Americans inhabited San Francisco Bay Region, and believe the Ohlone people settled in the Hunters Point area due to the availability of seasonal hunting and fish. Hunters Point was originally a private, commercial dry dock facility from 1869 until December 29, 1939, when the Navy purchased the property. The natural landscape of Hunters Point was significantly changed by extensive grading and flattening of the rocky hills and filling of the shoreline areas during the World War II and postwar periods. From 1945 until 1974, the Navy predominantly used the shipyard as a naval submarine and ship repair facility. At the height of operations, approximately 8,000 civilian workers were employed at the Shipyard. In addition to serving as a repair facility, the Shipyard was also the site of the Naval Radiological Defense Laboratory (NRDL) from 1948 to 1969. The purposes of the NRDL included radiological decontamination of ships exposed to atomic weapons testing as well as research and experiments on radiological decontamination, the effect of radiation on living organisms, and the effects of radiation on materials. In 1974, the Navy ceased shipyard operations, placing the Shipyard in industrial reserve and transferring control of the property to the Navy Office of the Supervisor of Shipbuilding, Conversion, and Repair in San Francisco. From May 1976 to June 1986, Triple A Machine Shop, Inc. leased most of the Shipyard from the Navy and operated a commercial ship repair facility. Cleanup Program at the Shipyard: In 1989, EPA placed the Shipyard on its National Priority List (NPL) which is a list of Federal Superfund Sites in the United States. There are approximately 1,300 Superfund sites on the NPL nationwide. The cleanup program at the Shipyard is conducted by the Navy pursuant to the Installation Restoration Program, a federally funded program established by the Department of Defense (DOD) to identify, investigate, and control the migration of hazardous substances at military and other DOD facilities. The Shipyard is being prepared for transfer under a program called Base Realignment and Closure or BRAC. A Federal Facilities Agreement (FFA), which governs the site cleanup process at the Shipyard, was signed September 28, 1990 with the final, revised version of the FFA signed in January 1992. Signatories to the FFA consist of the Navy, EPA, the California Department of Toxic Substances Control and the California Regional Water Quality Control Board. Under the FFA, the Navy is the lead agency responsible for the investigation and cleanup of the Shipyard in accordance with the Comprehensive Environmental Response Compensation and Liability Act (CERCLA). CERCLA is also known as the Federal Superfund Law. EPA is the lead regulatory agency. EPA, along with its partner regulatory agencies at California EPA, oversees and enforces Navy compliance with CERCLA to ensure the cleanup at the Shipyard is protective of human health and environment.
