Remedial (NPL) Program
The National Priorities List (NPL) is the list of sites of national priority among the known releases 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. Sites are listed on the NPL upon completion of assessment through the Pre-Remedial Program screening, public solicitation of comments about the proposed site, and obtainment of state support for the listing. States are required to pay a minimum of 10% of the cleanup costs and assume operations and maintenance responsibilities once the site is remediated or the remedy is stable and has been demonstrated effective for ten (10) years.
