National Oil and Hazardous Substances Pollution Contingency Plan; National Priorities List: Partial Deletion of the U.S. Coast Guard (USCG) Buoy Depot of the South Weymouth Naval Air Station Superfund Site

The Environmental Protection Agency (EPA) Region 1 announces the deletion of the U.S. Coast Guard (USCG) Buoy Depot of the South Weymouth Naval Air Station (NAS) Superfund Site (Site) located in Weymouth, MA, from the National Priorities List (NPL). The NPL, promulgated pursuant to section 105 of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) of 1980, as amended, is an appendix of the National Oil and Hazardous Substances Pollution Contingency Plan (NCP). This partial deletion pertains to the soil and groundwater at the USCG Buoy Depot (Operable Unit #10). The remaining operable units at South Weymouth NAS will remain on the NPL and are not considered for deletion as part of this action. The EPA and the Commonwealth of Massachusetts, through the Massachusetts Department of Environmental Protection (MassDEP), have determined that all appropriate response actions under CERCLA have been completed. However, the deletion of this parcel does not preclude future actions under Superfund.
