EPA final rule implements statutory addition of certain PFAS to TRI (including PFHxS‑Na)

EPA published a final rule in the Federal Register implementing the statutory (NDAA-driven) addition of certain PFAS to the Toxics Release Inventory (TRI) under EPCRA §313. The action codifies PFAS additions for TRI reporting, including sodium perfluorohexanesulfonate (PFHxS‑Na) for Reporting Year 2026, affecting TRI-covered facilities’ chemical tracking and reporting obligations. Compliance teams should verify TRI applicability (NAICS/sector coverage), update substance lists/SDS and tracking systems, and prepare for reporting consistent with TRI requirements and applicable thresholds (including special-concern treatment where applicable).
