On April 13, 2023, the U.S. Environmental Protection Agency (EPA) issued an Advance Notice of Proposed Rulemaking (ANPRM) requesting input on the potential designation of additional categories of per and poly-fluoroalkyl substances (PFAS) as hazardous substances under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), also known as Superfund. The ANPRM follows EPA’s September 2022 Proposed Rule, which, if finalized, would designate two of the most common PFAS as CERCLA hazardous substances and represents another step under the “PFAS Strategic Roadmap: EPA’s Commitments to Action 2021-2024,” a plan for taking an agency-wide approach to address PFAS under EPA’s various statutory and regulatory authorities. EPA will be accepting comments on the ANRPM until June 12, 2023.
What Are PFAS?
PFAS are a group of man-made chemicals identified by signature elemental bonds of fluorine and carbon, which are extremely strong and difficult to break down in the environment. As a result, PFAS are persistent and can withstand high temperatures and highly corrosive environments. While the PFAS family of chemicals includes the commonly known and used PFOA, PFOS, and GenX, there are more than 12,000 other compounds that are also classified as PFAS. PFAS can be present in water, soil, air, and food as well as materials found in homes and workplaces.
PFAS have been manufactured and used in a variety of industries around the globe, including in the United States since the 1940s. Because of their ability to repel water and oil, PFAS are used in many different types of products, including firefighting foam known as “AFFF,” stain-resistant carpets, roofing materials, coatings, food packaging, water-resistant outdoor clothing and gear, nonstick cookware, and boots, among others. …
