National Priority List (NPL)

The National Priority List (NPL) is a list maintained by the U.S. Environmental Protection Agency (EPA) that identifies the most serious contaminated sites needing cleanup. It helps prioritize resources and efforts for locations where hazardous substances, like chemicals or waste, threaten public health or the environment. Being on the NPL means a site is eligible for federal assistance to evaluate and remediate contamination, ensuring responsible cleanup and protection for nearby communities.
