# Identification of plan.
**AGENCY:**
Environmental Protection Agency (EPA).
**ACTION:**
Final rule; correction.
**SUMMARY:**
The Environmental Protection Agency (EPA) published a final rule in the *Federal Register* on July 7, 2021, entitled “Air Plan Approval; AL; NO <sub>X</sub> 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.
**DATES:**
This action is effective October 1, 2021.

**SUPPLEMENTARY INFORMATION:**
On July 7, 2021 (86 FR 35610), EPA published a final rule in the *Federal Register* entitled “Air Plan Approval; AL; NO <sub>X</sub> SIP Call and Removal of CAIR” which became effective on August 6, 2021. The final rule approved the addition of regulations to Alabama's State Implementation Plan (SIP) to maintain compliance with their nitrogen oxides (NO <sub>X</sub> ) SIP Call obligations for large non-electricity generating units (non-EGUs), the repeal of the State's regulations previously sunsetted regarding the NOx Budget Trading Program, and the repeal of the State's Clean Air Interstate Rule (CAIR) regulations. [^1] Additionally, the final rule conditionally approved state regulations into the SIP that establish monitoring and reporting requirements for units subject to the NO <sub>X</sub> SIP Call, including alternative monitoring options for certain sources.
[^1]*See* 86 FR 35610 (July 7, 2021) for information on the NO <sub>X</sub> SIP Call, NO <sub>X</sub> Budget Trading Program, and CAIR.
However, the rule contained two errors in the instructions regarding amendments to the table titled “EPA-Approved Alabama Regulations” found at 40 CFR 52.50(c). *See* 86 FR at 35614. Because of the errors in the amendatory instructions, the Office of the Federal Register was not able to incorporate some of the changes and placed an editorial note at the bottom of 40 CFR 52.50. Although the rational for incorporating these changes remains the same as presented in the July 7, 2021, rule, EPA is now correcting the CFR to appropriately display the approved rules in the South Carolina SIP.
**List of Subjects in 40 CFR Part 52**
Environmental protection, Air pollution control, Incorporation by reference, Intergovernmental relations, Nitrogen dioxide, Ozone, Particulate matter, Reporting and recordkeeping requirements, Sulfur oxides.
Dated: September 9, 2021.
John Blevins,
Acting Regional Administrator, Region 4.

1. The authority citation for part 52 continues to read as follows:
**Authority:**
