On December 20, 2019, the National Defense Authorization Act for Fiscal Year 2020 (NDAA) was signed into law. Among other provisions, section 7321 amends section 313 of the Emergency Planning and Community Right-to-Know Act (EPCRA) to include certain per- and polyfluoroalkyl substances (PFAS) on the EPCRA section 313 list of reportable toxic chemicals as of January 1, 2020. Specifically, the NDAA identifies 14 chemicals by name and/or chemical abstracts service registry number (CASRN) in section 7321(b) and identifies additional PFAS listed as (1) an active chemical substance in the February 2019 update to the TSCA Inventory released by EPA under section 8(b)(1) of the Toxic Substances Control Act (TSCA); and (2) subject to (as of December 20, 2019), the requirements in 40 CFR 721.9582 or 721.10536. This action will amend the EPCRA regulations to reflect the statutory addition of the PFAS chemicals covered by the NDAA to the list of chemical substances subject to reporting for the Toxic Release Inventory (TRI).
