US EPA final rule modifies the start of the TSCA §8(a)(7) PFAS reporting submission period

EPA published a final rule modifying when the submission period begins for the TSCA Section 8(a)(7) one-time PFAS reporting and recordkeeping rule (40 CFR Part 705). The change delays/reties the reporting window start to a future trigger (e.g., tied to the effective date of a forthcoming final rule revising substantive requirements, with a stated backstop date in the Federal Register notice). This affects entities that manufactured (including imported) PFAS during the covered lookback period because their compliance planning for data collection and submission timing must be adjusted to the revised start trigger and associated reporting window.
