EPA is proposing to add 16 individually listed per- and polyfluoroalkyl substances (PFAS) and 15 PFAS categories to the Toxics Release Inventory (TRI) list of toxic chemicals subject to reporting under the Emergency Planning and Community Right-to-Know Act (EPCRA) and the Pollution Prevention Act (PPA) to comply with the National Defense Authorization Act for Fiscal Year 2020 (NDAA). EPA also addresses how PFAS categories should be treated. Separately, EPA discusses what events may trigger the automatic addition of a PFAS to the TRI pursuant to the NDAA. This discussion does not propose to list chemicals to TRI pursuant to the NDAA, but rather describes what EPA documents and activities involving PFAS would trigger an automatic addition under the NDAA. Comments must be received on or before 9 December 2024.
