The National Priorities List (NPL) is the list of hazardous waste sites in the United States eligible for long-term remedial action (cleanup) financed under the federal Superfund program. Environmental Protection Agency (EPA) regulations outline a formal process for assessing hazardous waste sites and placing them on the NPL. The NPL is intended primarily to guide EPA in determining which sites warrant further investigation.
The inclusion of a facility in the National Priorities List does not reflect a judgment of its owner or operator or make the owner or operator take any action. It also does not assign any liability to any person or company. It serves as a source of information by identifying facilities or other hazardous substance releases that appear to warrant remedial actions
