U.S. Environmental Protection Agency Extends PFAS Reporting Rule Submission Period
On Monday, May 12, 2025, the U.S. Environmental Protection Agency (EPA) announced an interim final rule to extend the reporting period for the EPA’s rule requiring data submission on per- and polyfluoroalkylated substances (PFAS Reporting Rule).
U.S. Environmental Protection Agency Announces New PFAS Action Plan
On April 28, 2025, U.S. Environmental Protection Agency (EPA) Administrator Lee Zeldin announced the Agency’s plan to address per- and polyfluoroalkyl substances (PFAS) during the second Trump Administration. PFAS are manmade chemicals—of which there are thousands—commonly found in textiles, cookware, packaging, plastics, and firefighting foams. These “forever chemicals” are persistent in the environment and human body, as they do not break down and can accumulate over long periods of time. EPA’s outlined action plan calls upon its investigatory, regulatory, and enforcement powers under various statutes, including the Toxic Substances Control Act (TSCA), Clean Water Act (CWA), Safe Drinking Water Act (SDWA), Resource Conservation and Recovery Act (RCRA), and Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA).
U.S. Environmental Protection Agency Amends New Chemicals Review Process Under Toxic Substances Control Act
On December 18, 2024, the U.S. Environmental Protection Agency (EPA) published a final rule modifying regulations governing the new chemicals review process under the Toxic Substances Control Act (TSCA) (Final Rule). As amended by the 2016 Lautenberg Amendments, TSCA Section 5 establishes prior notice requirements before a new chemical can be manufactured or an existing chemical can be used in new ways.[1] The Final Rule updates EPA practices guiding its review of exemptions and safety determinations, as well as a submitter’s request to start manufacturing, and aligns the implementing regulations with the 2016 amendments.
Fifth Circuit Limits EPA’s Attempts to Regulate PFAS Under Toxic Substances Control Act in Inhance Technologies v. EPA
On March 21, 2024, the U.S. Court of Appeals for the Fifth Circuit vacated two U.S. Environmental Protection Agency (EPA) orders under Section 5 of the Toxic Substances Control Act (TSCA), holding that EPA had exceeded its statutory authority when it issued the orders in an attempt to regulate the manufacture of per- and polyfluorinated substances (PFAS) by petitioner Inhance Technologies, LLC (Inhance). The Fifth Circuit’s decision comes after EPA’s Office of Enforcement and Compliance Assurance announced its National Enforcement and Compliance Initiatives for Fiscal Years 2024 – 2027, which involve increased emphasis on addressing PFAS exposure and contamination through enforcement actions and potential additional regulations.
U.S. EPA Proposes First Enforceable PFAS Water Contamination Levels
On March 14, 2023, the U.S. Environmental Protection Agency (EPA) proposed its long-anticipated National Primary Drinking Water Regulation (NPDWR) to limit six common types of PFAS in drinking water. This is the first time EPA has sought to establish legally enforceable national PFAS[1] contamination levels for drinking water. This step represents the latest action under the Biden administration’s multistep plan to limit PFAS levels in the United States, building upon EPA’s October 2021 PFAS Strategic Roadmap and its pending proposal to designate certain PFAS as hazardous substances under CERCLA, the Comprehensive Environmental Response, Compensation, and Liability Act.
