EPA Proposes Significant Changes to PFAS Reporting Requirements Under the TSCA
In an article for The Legal Intelligencer, partner Charlie Dennen writes about the U.S. Environmental Protection Agency’s (EPA) proposed significant changes to PFAS reporting requirements under the Toxic Substances Control Act (TSCA). These updates aim to simplify compliance and reduce costs for manufacturers and importers. Key proposals include exemptions for low-concentration PFAS in mixtures, imported articles, and byproducts, as well as research and development chemicals. The rule also shortens the data submission period and removes reporting requirements for small manufacturers. These changes are expected to save industry up to $843 million in compliance costs. The EPA is seeking public input on the proposed changes until December 29, 2025, particularly regarding the exemptions and the amended data submission timeline.
