Download as PDF Federal Register / Vol. 86, No. 34 / Tuesday, February 23, 2021 / Proposed Rules procedures for changes that do not require a Non-Title V Permit from Rule 220, Section 404.3.e.; (7) the requirements for holding a public hearing from Rule 241, Section 310; and (8) the source obligation provision from Rule 241, Section 315. These requirements were moved to other rules or are already addressed in existing rules. The EPA finds these revisions acceptable. Other General Rule Revisions The MCAQD made several other minor wording and administrative changes to Rules 100, 200, 210, 220, 240, and 241. As discussed further in our TSD, these rule revisions are acceptable. We are proposing to fully approve Rules 100, 200, 210, 220, 230, 240 and 241 as part of the MCAQD’s general and NSR permitting programs because we have determined that these rules satisfy the substantive statutory and regulatory requirements of section 110(a)(2)(C) of the Act, parts C and D of title I of the Act, 40 CFR 51.160–51.166, and 40 CFR 51.307. Our TSD for this rulemaking contains a more detailed evaluation. III. Proposed Action and Public Comment As authorized in section 110(k)(3) of the Act, the EPA proposes to fully approve the MCAQD Rules 100, 200, 210, 220, 230, 240, and 241, because they fulfill all relevant requirements. We are accepting comments from the public on this proposal until March 25, 2021. If we finalize this action as proposed, our action would be codified through revisions to 40 CFR 52.120 (Identification of plan). IV. Incorporation by Reference In this rule, the EPA is proposing to include in a final EPA rule regulatory text that includes incorporation by reference. In accordance with requirements of 1 CFR 51.5, the EPA is proposing to incorporate by reference the MCAQD rules listed in Table 1 of this notice. The EPA has made, and will continue to make, these documents generally available electronically through www.regulations.gov and at the EPA Region IX Office (see the FOR FURTHER INFORMATION CONTACT section of this preamble for more information). submissions, the EPA’s role is to approve state choices, provided that they meet the applicable criteria of the Clean Air Act. Accordingly, this action merely approves state law as meeting federal requirements and does not impose additional requirements beyond those imposed by state law. For that reason, this action: • Is not a significant regulatory action subject to review by the Office of Management and Budget under Executive Orders 12866 (58 FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 2011); • Does not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.); • Is certified as not having a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.); • Does not contain any unfunded mandate or significantly or uniquely affect small governments, as described in the Unfunded Mandates Reform Act of 1995 (Pub. L. 104–4); • Does not have federalism implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999); List of Subjects in 40 CFR Part 52 Air pollution control, Environmental protection, Incorporation by reference, Intergovernmental relations, New source review, Ozone, Particulate matter, Reporting and recordkeeping requirements, Volatile organic compounds.
