After a site has gone through an initial Superfund assessment and investigation and the department determines cleanup is needed, the site is either placed on the U.S. Environmental Protection Agency's (EPA) National Priorities List (NPL), considered for cleanup under the State Superfund Cooperative Program or referred to EPA for a removal action. The NPL is EPA's list of the highest priority hazardous waste sites in the nation needing remedial investigation and cleanup actions. For information about all the NPL sites in the U.S., visit EPA's Superfund: National Priorities List.
