The former Bremerton Gas Works is located north of downtown Bremerton, Washington. The 2.8-acre property sits along Port Washington Narrows in Puget Sound, a designated estuary of national significance under the Clean Water Act (CWA), 33 U.S.C. § 1251 et seq. Available information indicates a history of hazardous releases and discharges of oil from the former Bremerton Gas Works and adjacent properties. The Bremerton Gas Works Site is the extent of the former Bremerton Gas Works in Kitsap County, Washington, adjacent parcels, and anywhere releases from the former gas works and adjacent parcels come to be located, including the aquatic environment of the Port Washington Narrows. Two species of federally listed endangered or threatened fish, steelhead trout (Oncorhynchus mykiss) and Chinook salmon (Oncorhynchus tshawytscha) occur in the Puget Sound in the vicinity of the former gas works and adjacent properties. Additionally, the areas of habitat around the former gas works are associated with many other species that have State, Tribe, and federal regulatory designations, such as but not limited to Essential Fish Habitat and Critical Habitat designated under fishery or species-specific management plans. This portion of Puget Sound is used as a sport and commercial fishery (shellfish and finfish), as well as for subsistence fishing by the Suquamish Indian Tribe of the Port Madison Reservation (Suquamish Tribe). These natural resources, and the uses thereof, have likely been injured by releases of hazardous substances and discharges of oil. The former gas works property was listed on the Superfund National Priorities List in May 2012. The EPA is in the early stages of the CERCLA remedial process.
