The U.S. Environmental Protection Agency issued a Notice of Intent on February 22 to delete three sites and partially delete eight other sites from the National Priorities List (NPL) while also requesting public comments on these proposed actions.

The NPL is an appendix of the National Oil and Hazardous Substances Pollution Contingency Plan (NCP).

The EPA and state agencies have determined that all appropriate response actions have been completed on the sites. However, this deletion does not preclude future actions under Superfund.

Ten of the 11 proposed sites involve groundwater contamination. On the three fully deleted sites, the groundwater portions are proposed to be deleted with two sites meeting drinking water standards. On the remaining sites, groundwater continues to be monitored or treated.

Comments regarding this proposed action must be submitted on or before March 24, 2023.

The proposed site deletions are listed below by name, location, full or partial deletion, and indication of groundwater contamination:

• Haviland complex, Town of Hyde Park, New York, full deletion, groundwater deleted and meeting drinking water standards
• Smithtown Ground Water Contamination, Smithtown, New York, full deletion, groundwater deleted and meeting drinking water standards
