Publication of New EPA Rule Designating PFOA and PFOS as CERCLA Hazardous Substances Starts the Clock for Potential Challenges

On May 8, 2024, the U.S. Environmental Protection Agency (EPA) published in the Federal Register its final rule designating perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) as hazardous substances under the Comprehensive Environmental Response, Compensation & Liability Act (CERCLA). The final rule, which EPA announced on April 17, 2024, and which will take effect July 8, 2024, is the first time EPA has ever invoked CERCLA Section 102 to designate a new substance as a hazardous substance via regulation. The publication of the rule starts the clock for any challenges to the rule, giving industry and other parties 90 days from publication to file any applicable legal challenges. Publication also triggers a congressional review period under the Congressional Review Act, giving Congress 60 “legislative days” to review the rule. EPA’s decision to release the rule now is noteworthy in that the review period likely will expire before the general election in November and potential changes in control of the House, Senate and White House.

PFAS

Per- and Polyfluoroalkyl substances (PFAS), sometimes called “forever chemicals,” are rising in public awareness, government regulation and related litigation. Companies that currently use or historically used or manufactured products containing PFAS are subject to increasing regulation and potential liability associated with the use, the impact on the environment, reporting and disposal of PFAS. Duane Morris’ dedicated group of professionals monitor, analyze and counsel clients on various aspects of PFAS, including companies who are developing technology to capture and eradicate PFAS from water and solids.
