On November 10, 2025, the United States Environmental Protection Agency (US EPA) released a pre-publication notice regarding the proposed changes to the Perfluoroalkyl and Polyfluoroalkyl Substances (PFAS) Data Reporting and Recordkeeping Rule Under the Toxic Substances Control Act (TSCA) [TSCA section 8(a)(7)]. The proposed changes seek to preserve essential PFAS data collection, while adding certain exemptions to ease compliance for companies. Read the US EPA press release here. Major proposed changes are summarized in Table 1 below.
Table 1 Proposed Changes to the PFAS Reporting Rule Under TSCA
Notes: CAS = Chemical Abstracts Service; CDX = Central Data Exchange; No. = Number; PFAS = Perfluoroalkyl and Polyfluoroalkyl Substances; TSCA = Toxic Substances Control Act; US EPA = United States Environmental Protection Agency.
Once the proposed rule is published in the Federal Register, US EPA will seek public comments on the proposed changes for 45 days in docket #EPA-HQ-OPPT-2020-0549.
Next Steps:
