PFAS Observer
In April 2023, the EPA issued an Advanced Notice of Proposed Rulemaking (ANPRM) requesting input on the designation of seven PFAS as “hazardous substances” under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). This NPRM followed a proposed rule released in August 2022, which would designate the two most ubiquitous PFAS—PFOA and PFOS—as hazardous substances.
