US EPA updates TSCA PFAS §8(a)(7) reporting submission-period start trigger (effective after forthcoming revision; includes backstop date)

EPA issued a final rule modifying the start of the TSCA Section 8(a)(7) PFAS one-time reporting submission period (40 CFR Part 705). As described in EPA materials, the prior fixed start date (April 13, 2026) is replaced with a trigger tied to a forthcoming revision to the PFAS 8(a)(7) rule, with a backstop date referenced in EPA’s pre-publication final rule materials. This changes when regulated entities that manufactured (including imported) PFAS during the covered lookback period must begin submitting required data and may affect internal compliance planning, supplier data collection, and system readiness.
