EPA issued a final rule compelling 23 states to take action for their impacts on the 2015 ozone National Ambient Air Quality Standards (NAAQS) in other states. The “Good Neighbor” provisions of the Clean Air Act prohibits certain ozone-precursor emissions from fossil-fuel-fired power plants by implementing an allowance-based trading program beginning in the 2023 ozone season. The action will prohibit emissions from certain other industrial stationary sources through limits and associated requirements beginning in the 2026 ozone season. Effective 60 days after publication in the Federal Register.

The EPA Administrator, Michael S. Regan, signed the following notice on 3/15/2023, and EPA is submitting it for publication in the Federal Register (FR). While we have taken steps to ensure the accuracy of this Internet version of the rule, it is not the official version of the rule for purposes of compliance. Please refer to the official version in a forthcoming FR publication, which will appear on the Government Printing Office’s govinfo website (https://www.govinfo.gov/app/collection/fr) and on Regulations.gov (https://www.regulations.gov) in Docket No. EPA-HQ-OAR-2021-0668. Once the official version of this document is published in the FR, this version will be removed from the Internet and replaced with a link to the official version.
