Our litigation and environmental teams recently discussed the DC Circuit’s ruling that rejected a challenge to the EPA’s listing of a site on the Superfund National Priorities List (NPL). This decision will inform listing decisions at other sites with subsurface contamination, and could lead to the listing of more industrial sites on the NPL. It also serves as a reminder that parties must evaluate and raise with EPA in the preliminary assessment and site listing process all potential challenges to EPA’s listing decision.
