The U.S. Environmental Protection Agency added seven per- and polyfluoroalkyl substances (PFAS) to the list of chemicals covered by the Toxics Release Inventory (TRI).
TRI data is reported to EPA annually by facilities in designated industry sectors and federal facilities that manufacture, process, or otherwise use TRI-listed chemicals above set quantities. The data include quantities of such chemicals that were released into the environment or otherwise managed as waste. Information collected through TRI allows communities to learn how facilities in their area are managing listed chemicals.
The data collected is available online and helps to support informed decision-making by companies, government agencies, non-governmental organizations and the public.
“With these additions to the Toxics Release Inventory, we’ll be collecting data on the release and management of almost 200 PFAS in communities across the country, furthering our efforts to better understand and protect people from these chemicals,” says Assistant Administrator for the Office of Chemical Safety and Pollution Prevention Michal Freedhoff. “We’ll also share this information with the public, empowering communities to engage with the facilities using these chemicals to prevent or reduce pollution.”
These seven PFAS were added to the TRI list pursuant to the Fiscal Year 2020 National Defense Authorization Act (NDAA), which provides the framework for the automatic addition of PFAS to TRI each year in response to specified EPA activities involving such PFAS. For TRI Reporting Year 2024 (reporting forms due by July 1, 2025), reporting is required for these seven additional PFAS, bringing the total PFAS subject to TRI reporting to 196.
Addition of PFAS with Final Toxicity Values
The 2020 NDAA includes a provision that automatically adds PFAS to the TRI list upon the Agency’s finalization of a toxicity value. Six PFAS were automatically added for Reporting Year 2024 due to EPA having finalized a toxicity value during 2023. Only these particular salt forms of the acids are added to the list.
- Ammonium perfluorohexanoate; Chemical Abstract Service Registration Number (CASRN) 21615-47-4
- Lithium bis[(trifluoromethyl)sulfonyl] azanide; CASRN 90076-65-6
- Perfluorohexanoic acid (PFHxA); CASRN 307-24-4
- 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
PFAS No Longer 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 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, 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. 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.
