The EPA is amending the data submission period for the TSCA PFAS reporting rule by changing the start date for submissions and making corresponding changes to the end dates for the submission period, i.e., the data submission period begins on 13 April 2026, and ends on 13 October 2026, with an alternate end date for small manufacturers reporting exclusively as article importers of 13 April 2027. As promulgated in October 2023, the regulation requires manufacturers (including importers) of perfluoroalkyl and polyfluoroalkyl substances (PFAS) in any year between 2011-2022 to report certain data to EPA related to exposure and environmental and health effects. This change is necessary because EPA requires more time to prepare the reporting application to collect this data. The Agency is separately considering reopening certain aspects of the rule to public comment. The delayed reporting date ensures that EPA has adequate time to consider the public comments and propose and finalize any modifications to the rule before the submission period begins. This interim final rule is effective on 13 May 2025. Comments must be received on or before 12 June 2025. POC is David Turk tele: 202-566-1527; email: turk.david@epa.gov.
