TSCA PFAS Reporting Postponed Again

The United States Environmental Protection Agency (“EPA”) has announced it will again delay the start of the data submission period for the Toxic Substances Control Act (“TSCA”) Section 8(a)(7) reporting requirement for per- and polyfluoroalkyl substances (“PFAS”), previously slated to begin April 13, 2026. According to a pre-published version of EPA’s rule modifying the submission period timeline, this action officially shifts the start of the reporting period to either January 31, 2027, or “to 60 days following the effective date of the agency’s forthcoming revision to the PFAS 8(a)(7) rule,” whichever is earlier.
