2019-08734. Air Quality State Implementation Plans; Arizona: Approval and Conditional Approval of State Implementation Plan Revisions; Maricopa County Air Quality Department; Stationary Source Permits; Correction

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Final rule; correction.

SUMMARY:

The Environmental Protection Agency (EPA) issued a final rule on April 5, 2019, entitled “Air Quality State Implementation Plans; Arizona: Approval and Conditional Approval of State Implementation Plan Revisions; Maricopa County Air Quality Department; Stationary Source Permits.” This document makes a minor change to the April 5, 2019, action to correct an error in the regulatory text for the rule.

DATES:

Effective: May 6, 2019.

SUPPLEMENTARY INFORMATION:

Background

The EPA issued “Air Quality State Implementation Plans; Arizona: Approval and Conditional Approval of State Implementation Plan Revisions; Maricopa County Air Quality Department; Stationary Source Permits” as a final rule on April 5, 2019 (84 FR 13543). This final rule approved revisions to the MCAQD's portion of the SIP for the State of Arizona. The EPA finalized full approval of Rules 210, 220, 240, and 241, and conditional approval of Rules 100 and 200. The revisions updated the MCAQD's New Source Review permitting program for new and modified sources of air pollution. For more information, please see the EPA's rulemaking action at https://www.regulations.gov under Docket ID No. EPA-R09-OAR-2017-0481, and the Federal Register publications for the proposed rule on June 11, 2018 (83 FR 26912), and the final rule on April 5, 2019 (84 FR 13543).

Need for Correction

As published, the regulatory text in the final rule contains an error that would remove previous SIP approvals in the Code of Federal Regulations that were not intended for deletion in this rulemaking. The EPA finds that there is good cause to make this correction without providing for notice and comment because neither notice nor comment is necessary and would not be in the public interest due to the nature of the correction which is minor, technical and does not change the obligations already existing in the rule. The EPA finds that the corrections are merely restoring the existing provisions of Table 4 that were unchanged by this action so that the provisions of Table 4 may be published correctly in the Code of Federal Regulations.

Correction of Publication

In the regulatory text to the final rule for “Air Quality State Implementation Plans; Arizona: Approval and Conditional Approval of State Implementation Plan Revisions; Maricopa County Air Quality Department; Stationary Source Permits” published April 5, 2019 (84 FR 13543), the EPA is correcting the error by setting out the newly revised Table 4 in paragraph (c), in its entirety, rather than the portion of Table 4 that was published.
