Site discovery and EPA notification are the first steps to the Superfund site cleanup process. After discovery, site information is gathered and entered into EPA's database of potential hazardous substance release sites, the "Comprehensive Environmental Response, Compensation and Liability Information System" (CERCLIS). The site then undergoes evaluation and administrative steps toward cleanup and deletion from the NPL.

The National Priorities List (NPL) is made up of sites with known or threatened releases of hazardous substances, pollutants or contaminants that meet the statutory criteria provided by the the Hazard Ranking System. CERCLA section 105(a)(8)(B) requires the U.S. EPA to develop this listing located in Appendix B of the National Contingency Plan (NCP) (40 CFR Part 300).


 Fiscal Year 2005 (which ended on Sept. 30), confirms that EPA completed work at 40 sites, for a cumulative total of 966 sites with work completed -- 62 percent of the top priority sites ranked on the National Priorities List. EPA conducted 665 ongoing cleanup projects at 422 sites (includes projects led by EPA, projects led by potentially responsible parties and federal facility sites). EPA funded new work at 17 projects across the country. Superfund also continued to prepare for future cleanup efforts by listing 18 new sites and proposing 12 sites to be added to the NPL.

Underscoring EPA's commitment to the "polluter pays" principle, the agency secured private party commitments of more than $1.1 billion in FY 05. Of this amount, potentially responsible parties agreed to conduct more than $857 million in future response work, and to reimburse EPA for $248 million in past costs.

CERCLIS is short for Comprehensive Environmental Response Compensation and Liability Information Systems and is the official repository for the site-specific and non site-specific data in support of the Superfund Process of CERCLA. It also contains the inventory of all potential hazardous substance release sites that have been identified in the United States.


The information contains data on hazardous waste sites collected from site inspections, preliminary assessments, remediation planning and actions taken at the sites. Data is available of 1982 to the present.

EPA provides online access to the CERCLIS database and standard CERCLIS site reports can be downloaded to a personal computer. You can also access CERCLIS directly from this site with links to specific CERCLIS Addresses
