The largest civil administrative penalty EPA has ever obtained under any federal environmental statute. The settlement resolves DuPont's violations related to the synthetic chemical perfluorooctanoic acid (PFOA) under the Toxic Substances Control Act (TSCA) and the Resource Conservation and Recovery Act (RCRA), which includes the four violations alleged in the Agency's two complaints filed against DuPont in July and December 2004,) and settles four additional counts involving information about PFOA that EPA obtained after initiating its action against DuPont. The settlement package requires DuPont to pay $10.25 million in civil penalties and perform Supplemental Environmental Projects worth $6.25 million.
