EPA final rule adds sodium perfluorohexanesulfonate (PFHxS-Na) to TRI starting Reporting Year 2026

EPA issued a final rule implementing the statutory addition of an additional PFAS—sodium perfluorohexanesulfonate (PFHxS-Na; CASRN 82382-12-5)—to the Toxics Release Inventory (TRI) list, beginning with Reporting Year 2026. This expands TRI PFAS reporting scope for covered facilities and affects annual Form R/Form A determinations and internal chemical inventory/reporting controls for PFAS handling and releases. Compliance teams should update TRI substance lists, facility applicability screens, and data collection processes for Reporting Year 2026 reporting.
