Comprehensive Environmental Response, Compensation and Liability Information System (CERCLIS), Version 2

The "Comprehensive Environmental Response, Compensation and Liability Information System, Version 2 (CERCLIS)" supports Environmental Protection Agency (USEPA) Headquarters and regions for the management and oversight of the Superfund program. It has two purposes: maintain an automated inventory of abandoned, inactive, or uncontrolled hazardous waste sites; and, act as a vehicle for regions to report status of major stages of site cleanup. A hotline will support CERCLIS operations at headquarters and regional program offices. The system provides a decentralized national system where each region controls and enters its respective data on regional systems. CERCLIS contains one entry for each hazardous waste disposal or spill site that has either been listed by the USEPA on the National Priorities List (NPL) for cleanup under Superfund or nominated for consideration for the NPL. More than 38,000 sites across the United States were covered by the database at the last update. The CERCLIS database is updated on a quarterly basis by the USEPA.
