Lynn L. Bergeson, “EPA Targets PFAS Cleanup,” Chemical Processing, September 23, 2022.

Cleanup costs under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) are about to get a lot more expensive. The U.S. Environmental Protection Agency (EPA) announced on September 6, 2022, that it will propose to designate perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), two of the most widely used per- and polyfluoroalkyl substances (PFAS), as hazardous substances under CERCLA. The rulemaking would also require entities immediately to report releases of PFOA and PFOS that meet or exceed the reportable quantity (RQ). This article discusses the proposal.
