EPA Tightens Grip on PFAS Chemicals

The EPA's one-time reporting rule under the Toxic Substances Control Act (TSCA) compels manufacturers and importers to disclose PFAS data for every year since January 1, 2011. This lookback has an estimated industry-wide compliance cost of over $800 million, a significant jump from the EPA's initial $10.8 million estimate, reflecting the complexity of digging through more than a decade of records. The reporting window for most manufacturers opens on April 13, 2026, and closes on October 13, 2026. This deadline requires companies to report a wide range of information, including production volumes, uses, worker exposure, and disposal methods for any PFAS-containing articles they manufactured or imported. Non-compliance carries steep penalties, with potential fines of up to $46,989 per violation, per day. In January 2025, the EPA added nine new PFAS to the Toxics Release Inventory (TRI), bringing the total to 205. For these chemicals, reporting is now required for even de minimis concentrations, as they are designated "Chemicals of Special Concern," eliminating previous exemptions. This change significantly widens the net for TRI reporting, which will be due by July 1, 2026, for the 2025 reporting year. The expanding regulations and litigation are forcing a shift in internal audit priorities. Audit plans are now being adapted to include comprehensive supply chain assessments to identify and mitigate PFAS-related risks. This involves mapping all tiers of the supply chain, from raw materials to packaging, to trace potential sources of contamination and ensure compliance with evolving government policies. Litigation risk is no longer confined to chemical producers. Lawsuits are increasingly targeting downstream manufacturers for failing to disclose the presence of PFAS in their products. Major settlements, such as 3M's agreement to pay up to $12.5 billion to public water suppliers, signal a new era of financial accountability that extends through the supply chain. As of early 2026, thousands of lawsuits remain pending in federal multidistrict litigation (MDL). This heightened regulatory and legal environment is triggering updates to SEC disclosures. Companies are being advised to reassess and update their risk factors and Management's Discussion and Analysis (MD&A) sections to specifically address potential liabilities from PFAS. Generic disclosures are being discouraged in favor of company-specific information regarding regulatory impacts, litigation exposure, and potential reputational harm. The operational advice from manufacturing-focused publications centers on proactive engagement with suppliers. Companies are encouraged to send targeted disclosure surveys to their supply chains to gather precise chemical composition data, as Safety Data Sheets (SDSs) often omit proprietary substances like PFAS. This due diligence is critical for both regulatory reporting and mitigating product obsolescence risk as state-level bans on PFAS in products like textiles and packaging accelerate.
