The National Priorities List (NPL) is the list of priorities among the known or threatened releases of hazardous substances, pollutants, or contaminants throughout the United States and its territories. The NPL is intended primarily to guide the EPA in determining which sites warrant further investigation. The NPL is updated periodically, as mandated by CERCLA. Where can interested parties find information about recent additions to the NPL?

Notification and listing of sites are published in the Federal Register. Depending on the action being taken by EPA, the Federal Register notice describes either the addition of sites to the NPL (final rule) or the proposal to add sites to the NPL (proposed rule). Notices for both actions provide a list of sites; background information about the NPL process, including information about the Superfund regulations; and other site actions. The proposed rule notice also provides information on how to submit comments on the proposed sites.

Information regarding the most recent NPL updates can be found on the EPA’s Superfund Web site at the following URL:
