EPA final rule adds sodium perfluorohexanesulfonate (PFHxS‑Na) to the Toxics Release Inventory (TRI) as a chemical of special concern

EPA finalized an update to the Toxics Release Inventory (TRI) adding sodium perfluorohexanesulfonate (PFHxS‑Na), a PFAS, to TRI reporting. EPA indicates TRI tracking/reporting for PFHxS‑Na begins with the 2026 reporting year (starting Jan 1, 2026). Facilities in TRI-covered sectors that manufacture, process, or otherwise use PFHxS‑Na must implement tracking systems for thresholds and releases/waste management for future TRI submissions; EPA states the first TRI reports including PFHxS‑Na are due July 1, 2027. EPA also states PFHxS‑Na is treated as a chemical of special concern with a 100 lb reporting threshold, increasing the likelihood of reporting for affected facilities.
