Biden Administration’s Intent to Designate PFOA and PFOS as CERCLA Hazardous Substances

On January 10, 2022, the U.S. Environmental Protection Agency took a significant step towards fulfilling a Biden Administration goal of bringing per- and polyfluoralkyl substances (“PFAS”) under the regulatory purview of the Comprehensive Environmental Response, Compensation & Liability Act (“CERCLA”) by submitting to the White House Office of Management and Budget a formal plan to designate two PFAS compounds – perfluorooctanoic acid (“PFOA”) and perfluorooctanesulfonic acid (“PFOS”) – as hazardous substances.

The EPA’s submittal of the proposed rule to the OMB comes after years of delay and several resets to its prior efforts to designate PFAS compounds as hazardous substances under CERCLA and triggers a 90-day review period. Provided the OMB does not take issue with EPA’s proposed rule, at the conclusion of the 90-day review period EPA can publish it in the Federal Register for public comment. Barring setbacks, the EPA could issue a final rule in the summer of 2023. This timeline matches what the Agency laid out in its October 2021 PFAS roadmap.[1] Once implemented, the final rule is likely to trigger a cascade of regulatory requirements including but not limited to release reporting. As the EPA noted in its Fall 2021 Statement of Regulatory Priorities, a hazardous substance designation “would require facilities across the country to report on PFOA and PFOS releases that meet or exceed the reportable quantity assigned to these substances [so as to] enable federal, state, tribal, and local authorities to collect information regarding the location and extent of releases.”[2] The final rule would also permit the EPA and other agencies to seek cost recovery or contribution for costs incurred in connection with cleanup of PFOA and PFOS contamination, as well as subject sites that are or were previously listed on the National Priorities List as Superfund sites to additional review for concerns related to PFAS contamination.

The recent action is yet another indication of the strong desire by the Biden Administration to implement an aggressive federal regulatory framework to address PFAS contamination. Time will tell whether and to what extent federal and state regulatory agencies are willing to utilize any forthcoming hazardous substance designations as a basis for re-engaging potentially responsible parties to fund and/or perform additional remedial measures at Superfund sites to address existing PFAS contamination.
