- EPA's Enviromapper consolidates data from seven EPA databases allowing you to retrieve information regarding toxic chemical releases, chemical permit compliance, hazardous waste handling processes, Superfund status, and air emission estimates for pollutants regulated under the Clean Air Act. You can ask Enviromapper to generate a report which will list all EPA regulated facilities located within the Zipcode you specify. Selecting a listed facility will bring up the environmental profile of the facility. You can also ask Enviromapper to generate a map which will locate EPA regulated facilities located within the Zipcode you specify.

Superfund-Related Information
The Comprehensive Environmental Response, Compensation, and Liability Information System (CERCLIS) is the official repository for site-and non-site-specific Superfund data in support of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). It contains information on hazardous waste site assessment and remediation from 1983 to the present.
