Abstract:  The Puget Sound Naval Shipyard (PSNS) Complex, also known as the Bremerton Naval Complex, includes a shipyard, fleet and industrial supply center, and associated tenants. The complex is located along the shoreline of Sinclair Inlet in Bremerton, Washington. Operable Unit A (OU A), located within the complex, encompasses approximately 12 acres of filled land. The entire site is bounded on the north and west by State Highway 304, on the east by Mooring G, and on the south by Sinclair Inlet. OU A is mostly surrounded by fencing and is regularly patrolled by base security.The Navy designated the Bremerton Naval Complex in 1891. The first dry-dock was completed in 1896, and military and industrial support activities have continued from that time to the present. Prior to the establishment of regulations governing waste disposal, some wastes used at the shipyard were disposed of or used as fill material, a practice considered acceptable at the time. The site now comprises a parking areas for visitors, naval personnel, and shipyard workers.In 1983, the Navy investigated the possibility of contamination at the site. From 1990 to 1991, a more concentrated study was performed at the Bremerton Naval Complex that concluded that no immediate cleanup was necessary. As the investigations continued, the Navy began to work with the U.S. Environmental Protection Agency (EPA) to investigate possible contamination from past practices at OU A. In 1994, PSNS was listed on the National Priorities List (NPL).
 
Remedy:  The selected remedy for OU A addresses the potential chemical exposures and associated risks by providing for capping, erosion protection, institutional controls, monitoring of groundwater, and habitat enhancements.
