"We have regularly reported on the EPA‘s long-anticipated rule to designate PFOA and PFOS as “hazardous substances” under CERCLA. In April 2024, the EPA also issued an Advanced Notice of Proposed Rulemaking (ANPRM), which aimed to have seven additional PFAS added to the CERCLA list of “hazardous substances.” EPA originally set a deadline of April 2025 to finalize the rule to add seven additional PFAS to CERCLA; however, EPA’s July 2024 Unified Agenda now indicates that the deadline to finalize the rule for the additional seven PFAS is “to be determined.”

The shift in priorities away from an expanded PFAS CERCLA designation is a significant development that anyone follows PFAS regulatory or litigation news.

CERCLA PFAS Scope Designation To Date

On January 10, 2022, the EPA submitted a plan for a PFAS Superfund designation to the White House Office of Management and Budget (OMB) when it indicated an intent to designate two legacy PFAS – PFOA and PFOS – as “hazardous substances” under the Comprehensive Environmental Response, Compensation & Liability Act (CERCLA, also known as the Superfund law). The EPA previously stated its intent to make the proposed designation by March 2022 when it introduced its PFAS Roadmap in October 2021. Under the Roadmap, the EPA planned to issue its proposed CERCLA designation in the spring of 2022. On August 12, 2022, a CERCLA PFAS designation took a significant step forward when the OMB approved the EPA’s plan for PFOA and PFOS designation. This step opened the door for the EPA to put forth its proposed designation of PFOA and PFOS under CERCLA and engage in the required public comment period."
