    EPA Delays TSCA PFAS Reporting Rule Again
    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.
