{"abstract":"The Environmental Protection Agency (EPA or the Agency) 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 one perfluoroalkyl substance that must be reported pursuant to the National Defense Authorization Act for Fiscal Year 2020 (FY 2020 NDAA) enacted on December 20, 2019. As this action is being taken to conform the regulations to a Congressional legislative mandate, notice and comment rulemaking is unnecessary.","action":"Final
