    Toxics Release Inventory PFAS Categories Expand Reporting Complexity
    In early October, the EPA proposed a new rule for the Toxics Release Inventory (TRI) that could change the way we currently report on PFAS. Currently, TRI requires individual reporting on 196 PFAS, but the new proposal introduces the concept of PFAS categories. We dive into the impact these changes could have on current TRI reporting and compliance if the proposal is approved.

    EPA Delays TSCA PFAS Reporting Rule Until July 2025
    In October 2023, EPA promulgated the final PFAS reporting and recordkeeping rule from the TSCA Section 8(a)(7) amendment by the 2020 NDAA. Originally intended to commence in November 2024 through November 2025, the agency issued a direct final amendment changing the reporting period to July 2025 through July 2026. EPA cites a lack of sufficient technological capacity and delays in reporting application development to accept data any sooner.
