The Environmental Protection Agency (EPA) published a final rule in the Federal Register on July 7, 2021, entitled "Air Plan Approval; AL; NO<INF>X</INF> SIP Call and Removal of CAIR." The July 7, 2021 rule, which became effective on August 6, 2021, contained an error in the amendatory instructions for the regulatory text. This correction does not change any final action taken by EPA in the July 7, 2021, final rule but makes a correction to final regulations.
