EPA final rule adds sodium perfluorohexanesulfonate (PFHxS‑Na) to TRI as a PFAS chemical of special concern; first reporting due July 1, 2027

EPA finalized a rule adding sodium perfluorohexanesulfonate (PFHxS‑Na) to the Toxics Release Inventory (TRI) PFAS reporting list as a chemical of special concern. Covered facilities must begin tracking PFHxS‑Na releases and other TRI reportable activities starting with the reporting year that begins January 1, 2026. EPA indicates the TRI reporting threshold is 100 lbs, and the first TRI submissions including PFHxS‑Na are due July 1, 2027. Compliance teams should assess whether operations manufacture, process, or otherwise use PFHxS‑Na and update TRI data collection, recordkeeping, and supplier/customer communication workflows accordingly.
