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

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Final rule.

SUMMARY:

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.

DATES:

This action is effective August 30, 2019.

EPA maintains the NPL as the list of sites that appear to present a significant risk to public health, welfare, or the environment. Deletion of a site from the NPL does not preclude further remedial action. Whenever there is a significant release from a site deleted from the NPL, the deleted site may be restored to the NPL without application of the hazard ranking system. Deletion of portions of a site from the NPL does not affect responsible party liability, in the unlikely event that future conditions warrant further actions.
