**SUPPLEMENTARY INFORMATION:**
Throughout this document “we,” “us,” and “our” means the EPA.
**I. Background**
The background for this action is discussed in detail in our August 22, 2023, proposal (88 FR 57014) and the accompanying Technical Support Document (TSD), available in the docket for this rule. In our August 2023 proposal we proposed to approve portions of the revisions to the Arkansas State Implementation Plan (SIP) including revisions to the Arkansas Pollution Control and Ecology Commission's Regulation No. 19, *Rules of the Arkansas Plan of Implementation for Air Pollution Control* submitted by the Arkansas Department of Energy and Environment, Division of Environmental Quality (ADEQ) via the Arkansas Governor's Office on June 22, 2022. The proposal included revisions to remove certain outdated provisions and update other provisions that are incorporated into Regulation 19. Specific provisions to be partially repealed are those in Chapter 10 of APC&EC Regulation 19 regarding the control of volatile organic compounds (VOC) from certain source categories in Pulaski County, and provisions repealed from the Clean Air Interstate Rule (CAIR) in Chapter 14, and informational provisions regarding sources eligible or subject to best available retrofit technology (BART) requirements for Regional Haze in Chapter 15. All of the repealed provisions were either superseded by other rules or otherwise no longer necessary. One of the revisions restructured the regulations and organized them as “rules,” such that “Regulation No. 19” became “Rule No. 19,” * Rules of the Arkansas Plan of Implementation for Air Pollution Control, * with corresponding chapters and appendices. Most of the revisions are administrative in nature and make the Arkansas SIP current with applicable Federal Rules. We did not receive any comments during the requisite comment period regarding our August 2023 proposal.
**II. Final Action**
We are approving portions of the revisions submitted by the State of Arkansas on June 22, 2022. We are finalizing the action without changes from our August 2023 proposal. Specifically, we are approving the following submitted revisions to Regulation 19: Revisions to Chapters 1, 2, 3, 4, 5, 6, 7, 9, 11, 13, 15, and Appendices A and B; the partial repeal of Regulation 19, Chapter 10 and repeal of Regulation 19, Chapters 14, and 16; and the new provision of Regulation 19, Chapter 18. Finally, we are approving the revision to rename Regulation 19 as Rule 19. These changes reflect the current organizational structure of ADEQ, remove outdated information, and make non-substantive formatting edits. This action is being taken under section 110 of the Act.
**III. Environmental Justice Consideration**
The EPA reviewed demographic data for groups of populations living within Pulaski County, Arkansas. The EPA then compared the data to the State of Arkansas and the national average for each of the demographic groups. The result of this analysis is discussed in detail in our proposal; and is provided for informational and transparency purposes.
This final action revises portions of the Arkansas SIP including revisions to Regulation 19 of the Arkansas Plan of Implementation for Air Control. We expect that this action and resulting emissions reductions will generally be neutral or contribute to reduced environmental and health impacts on all populations in the State of Arkansas, including people of color and low-income populations. The revisions provide updates to the SIP and improve clarity in the SIP so that the public can read and understand what is currently in the SIP. Further, there is no information in the record indicating that this action is expected to have disproportionately high or adverse human health or environmental effects on a particular group of people.
**IV. Incorporation by Reference**
In this rule, the EPA is finalizing regulatory text that includes incorporation by reference. In accordance with requirements of 1 CFR 51.5, the EPA is finalizing the incorporation by reference the revisions to the Arkansas regulations as described in Section II of this preamble, Final Action. The EPA has made, and will continue to make, these materials generally available through *www.regulations.gov* (please contact the person identified in the *FOR FURTHER INFORMATION CONTACT* section of this preamble for more information). Therefore, these materials have been approved by EPA for inclusion in the SIP, have been incorporated by reference by EPA into that plan, are fully federally enforceable under sections 110 and 113 of the CAA as of the effective date of the final rule of EPA's approval, and will be incorporated in the next update to the SIP compilation.
**V. Statutory and Executive Order Reviews**
Under the Clean Air Act, the Administrator is required to approve a SIP submission that complies with the provisions of the Clean Air Act and applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in reviewing SIP submissions, EPA's role is to approve state choices, provided that they meet the 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 14094 (88 FR 21879, April 11, 2023);
• 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);
• Is not subject to Executive Order 13045 (62 FR 19885, April 23, 1997) because it approves a state program;
• Is not a significant regulatory action subject to Executive Order 13211 (66 FR 28355, May 22, 2001); and
• Is not subject to requirements of Section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) because application of those requirements would be inconsistent with the Clean Air Act.
Executive Order 12898 (Federal Actions To Address Environmental Justice in Minority Populations and Low-Income Populations, 59 FR 7629, February 16, 1994) directs Federal agencies to identify and address “disproportionately high and adverse human health or environmental effects” of their actions on minority populations and low-income populations to the greatest extent practicable and permitted by law. EPA defines environmental justice (EJ) as “the fair treatment and meaningful involvement of all people regardless of race, color, national origin, or income with respect to the development, implementation, and enforcement of environmental laws, regulations, and policies.” [^1] EPA further defines the term fair treatment to mean that “no group of people should bear a disproportionate burden of environmental harms and risks, including those resulting from the negative environmental consequences of industrial, governmental, and commercial operations or programs and policies.” [^2]
[^1] See *https://www.epa.gov/environmentaljustice/learn-about-environmental-justice.*
[^2]*https://www.epa.gov/environmentaljustice/learn-about-environmental-justice.*
ADEQ did not evaluate environmental justice considerations as part of its SIP submittal; the CAA and applicable implementing regulations neither prohibit nor require such an evaluation. The EPA performed an environmental justice analysis, as is described above in the section titled, “Environmental Justice Considerations.” The analysis was done for the purpose of providing additional context and information about this rulemaking to the public, not as a basis of the action. Due to the nature of the action being taken here, this action is expected to have a neutral to positive impact on the air quality of the affected area. In addition, there is no information in the record upon which this decision is based inconsistent with the stated goal of E.O. 12898 of achieving environmental justice for people of color, low-income populations, and Indigenous peoples.
In addition, the SIP is not approved to apply on any Indian reservation land or in any other area where EPA or an Indian tribe has demonstrated that a tribe has jurisdiction. In those areas of Indian country, the rule does not have tribal implications and will not impose substantial direct costs on tribal governments or preempt tribal law as specified by Executive Order 13175 (65 FR 67249, November 9, 2000).
This action is subject to the Congressional Review Act, and the EPA will submit a rule report to each House of the Congress and to the Comptroller General of the United States. This action is not a “major rule” as defined by 5 U.S.C. 804(2).
Under section 307(b)(1) of the CAA, petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by February 27, 2024. Filing a petition for reconsideration by the Administrator of this final rule does not affect the finality of this action for the purposes of judicial review nor does it extend the time within which a petition for judicial review may be filed, and shall not postpone the effectiveness of such rule or action. This action may not be challenged later in proceedings to enforce its requirements. (See section 307(b)(2).)
