Current Status
On April 28, 2025, EPA announced it intends to prioritize PFAS contamination using multiple statutory authorities to address the environmental and public health risks, including the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). EPA’s announcement explains the Agency will work with Congress to exempt “passive” potentially responsible parties from CERCLA liability for PFAS contamination.
The Biden administration finalized a rule designating two common PFAS chemical sub-types as hazardous substances under CERCLA. Industry and trade associations challenged that rule in the DC Circuit. At the Trump Administration’s request, the court is holding the case in abeyance through April 25, 2025. Chamber of Commerce of the United States of America, et al v. EPA, et al, No. 24-01193 (D.C. Cir.).
Why it Matters
PFAS, often called “forever chemicals,” are a family of man-made chemicals featuring a strong carbon fluorine bond that makes the chemicals extremely durable. Over 26,000 sites in the US, including 126 military facilities, are contaminated with PFAS according to recent studies. At high levels of exposure, PFAS have been shown to cause serious human health problems.
CERCLA provides EPA broad authority to order, conduct, and recover costs for the cleanup of hazardous substances. EPA’s designation of two PFAS as hazardous substances grants the Agency full use of CERCLA’s authority to address PFAS contamination, including the use of the Superfund Trust to pay for PFAS cleanups when no liable parties responsible for the contamination exist. The Superfund trust is a government account funded by a levy on the chemical industry.
