The EPA is taking final action to revise the start of the reporting period for the Perfluoroalkyl and Polyfluoroalkyl Substances (PFAS) Reporting and Recordkeeping Rule (PFAS Reporting Rule). Pursuant to this action, the submission period for the PFAS Reporting Rule will begin on 31 January 2027, or 60 days following the effective date of a forthcoming final rule on the substantive requirements of the PFAS Reporting Rule, whichever is earlier. This final rule is effective on 13 April 2026. POC is Carolyn Hammack, tele: (202) 566-0521; email: Hammack.Carolyn@epa.gov. (Federal Register 13 April 2026 [Rule] Pages 18786-18789)
