EPA issues final rule modifying start of TSCA §8(a)(7) PFAS reporting submission period (60-day trigger; Jan 31, 2027 backstop)

EPA finalized a rule modifying the start of the submission period for TSCA §8(a)(7) PFAS reporting (40 CFR part 705). The submission period will begin on January 31, 2027, or 60 days after the effective date of a forthcoming final rule that will make substantive revisions to the PFAS reporting rule—whichever is earlier. This changes the prior planned April 13, 2026 start and affects entities that manufactured or imported PFAS during the covered lookback period by shifting compliance planning to the new trigger/backstop dates and requiring monitoring of the forthcoming final revision that starts the 60-day clock.
