EPA to Designate Certain PFAS Chemicals as Hazardous Substances

The U.S. Environmental Protection Agency is proposing to designate two of the most widely used per- and polyfluoroalkyl substances as hazardous substances under the Comprehensive Environmental Response, Compensation, and Liability Act.

The Aug. 26 proposal applies to perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), including their salts and structural isomers, and is based on what the EPA says is significant evidence that PFOA and PFOS may present a substantial danger to human health or welfare or the environment. 

“Communities have suffered far too long from exposure to these forever chemicals. The action announced today will improve transparency and advance EPA’s aggressive efforts to confront this pollution, as outlined in the Agency’s PFAS Strategic Roadmap,” says EPA Administrator Michael Regan. “Under this proposed rule, EPA will both help protect communities from PFAS pollution and seek to hold polluters accountable for their actions.”  

If finalized, the rulemaking would trigger reporting of PFOA and PFOS releases, providing the EPA with improved data and the option to require cleanups and recover cleanup costs to encourage better waste management. 

If this designation is finalized, releases of PFOA and PFOS that meet or exceed the reportable quantity would have to be reported to the National Response Center, state or Tribal emergency response commissions, and the local or Tribal emergency planning committees. A release of these or any other hazardous substance will not always lead to the need to clean up or add a site to the National Priorities List (NPL), liability, or enforcement action. EPA says it anticipates that a final rule would encourage better waste management and treatment practices by facilities handling PFOA or PFOS. The reporting of a release could potentially accelerate privately financed cleanups and mitigate potential adverse impacts on human health and the environment. 

Additionally, the EPA says the proposed rule would — in certain circumstances — facilitate making the polluter pay by allowing EPA to seek to recover cleanup costs from a potentially responsible party or to require such a party to conduct the cleanup. In addition, federal entities that transfer or sell their property will be required to provide notice about the storage, release, or disposal of PFOA or PFOS on the property and a covenant (commitment in the deed) warranting that it has cleaned up any resulting contamination or will do so in the future, if necessary, as required under CERCLA 120(h). 

EPA will be publishing the Notice of Proposed Rulemaking in the Federal Register in the next several weeks. Upon publication, EPA welcomes comments for a 60-day comment period. 

As a subsequent step, EPA anticipates issuing an Advance Notice of Proposed Rulemaking after the close of the comment period on today’s proposal to seek public comment on designating other PFAS chemicals as CERCLA hazardous substances.
