EPA is updating the list of chemicals subject to toxic chemical release reporting under the Emergency Planning and Community Right-to-Know Act (EPCRA) and the Pollution Prevention Act (PPA). Specifically, this action updates the regulations to identify nine per- and polyfluoroalkyl substances (PFAS) that must be reported pursuant to the National Defense Authorization Act for Fiscal Year 2020 (FY2020 NDAA) enacted on 20 December 2019. As this action is being taken to conform the regulations to a Congressional legislative mandate, notice and comment rulemaking is unnecessary. This final rule is effective 5 February 2025.
