The year began with the addition of nine per- and polyfluoroalkyl substances (PFAS) to the list of chemicals covered by the Toxics Release Inventory (TRI). The U.S. Environmental Protection Agency (USEPA) collects the data annually from 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 chemicals that were released into the environment or otherwise managed as waste.
Addition of PFAS with Final Toxicity Values
The nine PFAS were automatically added for Reporting Year 2025 due to USEPA having finalized a toxicity value during 2024 and whose identity is not claimed as confidential business information. The nine PFAS are:
- Ammonium perfluorodecanoate (PFDA NH4) (3108-42-7)
- Sodium perfluorodecanoate (PFDA-Na) (3830-45-3)
- Perfluoro-3-methoxypropanoic acid (377-73-1)
- 6:2 Fluorotelomer sulfonate acid (27619-97-2)
- 6:2 Fluorotelomer sulfonate anion (425670-75-3)
- 6:2 Fluorotelomer sulfonate potassium salt (59587-38-1)
- 6:2 Fluorotelomer sulfonate ammonium salt (59587-39-2)
- 6:2 Fluorotelomer sulfonate sodium salt (27619-94-9)
- Acetic acid, [(γ-ω-perfluoro-C8-10-alkyl)thio] derivs., Bu esters (3030471-22-5)
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, 2026.
The nine newly added PFAS, along with the previous 196 TRI-listed PFAS, are also subject to USEPA’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.
Information collected through TRI allows communities to learn how facilities in their area are managing listed chemicals. The data collected is available online and aims to support informed decision-making by companies, government agencies, non-governmental organizations, and the public.
