• Perfluoropropanoic acid (PFPrA); CASRN 422-64-0 • Sodium perfluorohexanoate; CASRN 2923-26-4 • 1,1,1-Trifluoro-N- [(trifluoromethyl)sulfonyl] methanesulfonamide; CASRN 82113-65-3 Addition of PFAS no longer claimed as confidential business information Under NDAA Section 7321(e), EPA must review confidential business information (CBI) claims before adding a PFAS to the TRI list if the chemical identity is subject to a claim of protection from disclosure under 5 U.S.C. 552(a). EPA previously identified one PFAS for addition to the TRI list based on the NDAA’s provision to include specific PFAS upon the NDAA’s enactment. However, due to CBI claims related to its identity, this PFAS was not added to the TRI list at that time. The identity of this chemical was subsequently declassified in an update to the Toxic Substances Control Act Inventory (www.epa.gov/ tsca-inventory) in February 2023. Because its identity is no longer confidential, the following chemical was added to the TRI list: • Betaines, dimethyl (.gamma.- .omega.-perfluoro-.gamma.- hydro-C8-18-alkyl); CASRN 2816091-53-7 As of January 1, 2024, facilities that are subject to reporting requirements for these chemicals should begin tracking their activities involving these PFAS as required by Section 313 of the Emergency Planning and Community Right-to-Know Act. Reporting forms will be due by July 1, 2025. These seven newly added PFAS, along with the previous 189 TRI-listed PFAS, are also subject to EPA’s action in October 2023 to classify all PFAS subject to TRI reporting as chemicals of special concern (www.epa.gov/ newsreleases/epa-finalizes-rule- require-enhanced-pfas-reporting- toxics-release-inventory) . Among other impacts, this removes the use of a reporting exemption that allowed facilities to avoid reporting information on PFAS when those chemicals were used in small concentrations.
