The analysis of PFAS by EPA 1633A and ASTM D8421 is part of the U.S. EPA’s Methods Update Rule (MUR) Rule 22. The action will promulgate EPA into 40 CFR Part 136. Also part of this action, PFAS method ASTM D8421 is proposed to be codified.
The PFAS reporting period under the Toxic Substances Control Act (TSCA) has been extended six months. The U.S EPA announced direct final and parallel proposed rules that delay the reporting period for the new TSCA PFAS requirement. Previously scheduled to begin the reporting period on November 12, 2024, the beginning of the reporting period is now delayed until July 2025.
The U.S. EPA recently finalized a rule that will provide the largest-ever dataset of per- and polyfluoroalkyl substances (PFAS) manufactured and used in the United States. The finalized reporting rule under the Toxic Substances Control Act (TSCA) is a statutory requirement with the National Defense Authorization Act (NDAA - FY2020).
The U.S. Environmental Protection Agency (EPA) formally announced the issuance of the next Toxic Substances Contract Act (TSCA) test order requiring PFAS testing. The new test order is being made under the National PFAS Testing Strategy. The EPA announced the action on January 4, 2023, which orders companies to conduct and submit testing for the PFAS substance HFPO. HFPO (CAS # 428-59-1), also known as trifluoro(trifluoromethyl)oxirane, is used in plastics manufacturing.
