Environmental Alert
(By Matthew Wood and Mackenzie Moyer)
On August 26, 2022, the U.S. Environmental Protection Agency (EPA) issued a pre-publication version of its Proposed Rule which would designate two PFAS chemicals as “hazardous substances” under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), commonly known as Superfund (Proposed Rule). Specifically, the Proposed Rule would list perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) – the two most common and well-studied PFAS – and their salts and isomers as hazardous substances under CERCLA. This is the first time EPA is making such designations by exercising its authority under CERCLA Section 102, 42 U.S.C. § 9602. Until now, CERCLA has always defined hazardous substances by reference to other statutes (e.g., the Clean Water Act and the Resource Conservation and Recovery Act).
In the Proposed Rule, EPA identified five broad categories of potentially affected entities: (1) PFOA/PFOS manufacturers (including importers and importers of articles); (2) PFOA/PFOS processors; (3) manufacturers of products containing PFOA/PFOS; (4) downstream product manufacturers and users of PFOA/PFOS products; and (5) waste management and wastewater treatment facilities. Potentially affected industries include aviation operations, chemical manufacturing, firefighting foam manufacturers, fire departments and training facilities, polymer manufacturers, and waste management and remediation services.
In the lead-up to issuance of the Proposed Rule, certain entities, such as drinking water utilities, wastewater utilities, and landfill operators, expressed concerns that they could face significant new liabilities for contamination originating from others. In its accompanying announcement, EPA said, without identifying specific industries, that it is “focused on holding responsible those who have manufactured and released significant amounts of PFOA and PFOS into the environment” and intends to use its “enforcement discretion” to “ensure fairness for minor parties who may have been inadvertently impacted by the contamination.” EPA further said that it will continue to engage with impacted communities, wastewater utilities, businesses, farmers, and other parties throughout the consideration of the Proposed Rule. …
