EPA announced an interim final rule to extend the dates of the reporting period for data submitted on the manufacture of perfluoroalkyl or polyfluoroalkyl substances (PFAS). This extension will allow EPA to further develop and test the software being used to collect the data from manufacturers, thereby providing critical feedback to EPA, including what additional guidance would be useful for the reporting community. Under section 8(a)(7) of the Toxic Substances Control Act (TSCA), EPA finalized a rule in October 2023 requiring anyone who has manufactured (including imported) a PFAS in any year from 2011 through 2022 to submit information to EPA regarding manufacturing, use, disposal, byproducts, worker exposures, and environmental and health effects of those PFAS. This interim final rule delays the start of the submission period by nine months, from 11 July 2025 to 13 April 2026. Submissions will now be due by 13 October 2026, for most manufacturers, and by 13 April 2027, for small manufacturers reporting exclusively as article importers.
