The Environmental Protection Agency (EPA) is correcting the erroneous incorporation of cross-references into the North Carolina State Implementation Plan (SIP) using the Clean Air Act (CAA or Act) error correction provision. EPA has determined that portions of its May 23, 2019, July 17, 2020, and March 1, 2021, final SIP rulemaking actions were in error and that it is appropriate to correct those actions by removing specific cross-references in the permitting rules from the SIP.
