EPA proposes changes to TSCA PFAS §8(a)(7) reporting requirements to add exemptions and adjust reporting mechanics

EPA issued a proposed rule to revise the TSCA §8(a)(7) PFAS one-time reporting and recordkeeping rule (40 CFR Part 705). The proposal would add/clarify exemptions (including a de minimis concept referenced in the research, and exemptions related to imported articles, byproducts, impurities, R&D, and non-isolated intermediates), make technical corrections, and adjust reporting mechanics/submission period. Compliance teams tracking PFAS data obligations should review applicability changes and prepare comments during the open comment period once published in the Federal Register.
