Between 1869 and 1939, Hunters Point Naval Shipyard performed as a commercial dry dock unit. In late1939 the U.S. Navy purchased the property, and until 1945 the Navy used the Shipyard to repair and maintain wartime vessels. In 1946 the Navy established the Naval Radiological Defense Laboratory (NRDL) on the Hunters Point Shipyard site. The NRDL was tasked with studying radioactive waste disposal, the decontamination of naval ships exposed to testing, and other related studies, including Operation Crossroads. The NRDL ceased operation in 1969, and in 1974 the U.S.Navy deactivated the Shipyard. Between1976 and 1984, the property was leased for commercial use. In 1991 Hunters Point was closed permanently following the Defense Base and Realignment Closure Act of 1990. Due to the past activities that occurred on site, action is in progress to clean up the area. This effort  is under the guidance of the Naval Facilities Engineering Command (NAVFAC)’s Base Realignment and Closure (BRAC) Program Management Office. Also, the site is listed as a Superfund Site on the U.S. Environmental Protection Agency’s National Priorities List (NPL): Hunters Point Naval Shipyard, San Francisco, CA.
