# [Amended]
**AGENCY:**
Environmental Protection Agency (EPA).
**ACTION:**
Direct final rule.
**SUMMARY:**
Pursuant to the Federal Clean Air Act (CAA or the Act), the Environmental Protection Agency (EPA) is approving portions of the revisions to the Arkansas State Implementation Plan (SIP) submitted by the Arkansas Department of Environmental Quality (ADEQ) on March 24, 2017. Most of the revisions are administrative in nature and make the SIP current with Federal rules. The EPA is also making ministerial changes to the Code of Federal Register (CFR) to reflect SIP actions pertaining to the Arkansas Prevention of Significant Deterioration (PSD) program.
**DATES:**
This rule is effective on November 6, 2018 without further notice, unless the EPA receives relevant adverse comment by September 7, 2018. If the EPA receives such comment, the EPA will publish a timely withdrawal in the *Federal Register* informing the public that this rule will not take effect.

**SUPPLEMENTARY INFORMATION:**
Throughout this document “we,” “us,” and “our” means the EPA.
**I. Background**
The SIP is a set of air pollution regulations, control strategies, and technical analyses developed by the state to ensure that the state meets the National Ambient Air Quality Standards (NAAQS). These ambient standards are established under section 109 of the Act and they currently address six criteria pollutants: Carbon monoxide, lead, nitrogen dioxide, ozone, particulate matter, and sulfur dioxide. The SIP is required by Section 110 of the Act and can be extensive, containing state regulations or other enforceable documents and supporting information such as emission inventories, monitoring networks, and modeling demonstrations.
On March 24, 2017, the Governor of Arkansas submitted to the EPA revisions to the Arkansas SIP. The submittal includes revisions to the Regulations of the Arkansas Plan of Implementation for Air Pollution Control enacted at Arkansas Annotated Code (“Ark. Code Ann.”) Regulation 19 (“Reg. 19”), Chapters 1-5, 7, 9, 11, 13-15, Appendix A, and Appendix B, and the Infrastructure and NAAQS SIPs. EPA has taken separate action on the following portions of this submittal: (1) On December 21, 2017, EPA approved the revisions to Reg. 19, Chapter 2, that address the definition of “Volatile Organic Compounds” (see 82 FR 60517); (2) On February 14, 2018, EPA approved the Infrastructure portion (see 83 FR 6470); (3) On June 29, 2018, EPA approved the revisions to Reg. 19, Chapter 4, that address Minor New Source Review (see 83 FR 30553); And, (4) on June 29, 2018, EPA proposed to approve the revisions that address interstate transport requirements for the 2012 PM <sub>2.5</sub> NAAQS and the revisions to Reg. 19, Chapter 2 and Appendix B, that address the definition of 2012 PM <sub>2.5</sub> in the definition of “NAAQS” and the table for “Particle Pollution, PM <sub>2.5</sub> ” (see 83 FR 30622). Because these prior EPA actions did not address all the submitted revisions to Reg. 19, Chapter 2 and Appendix B, today's action addresses the remaining submitted revisions to Reg. 19, Chapter 2 and Appendix B, and the submitted revisions to Reg. 19, Chapters 1, 3, 5, 13, 14, and 15. For a detailed list of each revision with our evaluation, please see our Technical Support Document (TSD) in the docket for this rulemaking.
**II. Summary of Revisions to the Arkansas SIP and EPA Evaluation**
**A. Non-Substantive Changes**
Non-substantive changes were made to Regulation 19, Chapter 1, Sections 101 and 103; Chapter 2 definitions; Chapter 3, Sections 301 and 304; Chapter 5, Sections 502-504; Chapter 13, Sections 1303 and 1308; Chapter 14, Section 1401; and Chapter 15, Sections 1502 and 1504 such as edits to acronyms, punctuation and section symbols. A complete listing of the non-substantive changes is in the TSD for this action. These changes are being approved here to maintain consistency between State rules and the approved SIP.
**B. Regulation 19, Chapter 2—Definitions**
Two definitions, “NAAQS state implementation plan or NAAQS SIP” and “State implementation plan or SIP” are new—these definitions are applicable to revised provisions in this SIP submittal. Several other revisions provide current references and publication dates for the specified Federal regulations within the definition. These revisions are necessary because Arkansas does not incorporate changes to the Federal regulations by reference prospectively and thus, must update its rules as Federal regulations are revised. For example, when the EPA revises test methods to allow the use of newly approved alternative procedures, the State must revise their state rules to incorporate the date of that Federal action. We find these revisions approvable.
In addition, the revisions to the definition for “CO2 equivalent emissions” delete a sentence commonly referred to as EPA's Biomass Deferral language, which EPA disapproved as a revision to the Arkansas SIP on May 23, 2016 (see 81 FR 32239 and 40 CFR 52.172). Because of our disapproval (see 81 FR 32239), the Biomass Deferral language was never in the Arkansas approved SIP and thus, the State's removal of this language from its State rules is a non-substantive change. Because the submitted revisions delete previously disapproved language, we are removing the prior disapproval listed in 40 CFR 52.172(c) as described in paragraph *D* of this action.
**C. Regulation 19, Appendix B—National Ambient Air Quality Standards List**
The revisions to the tables for Lead, PM <sub>2.5</sub> , and PM <sub>10</sub> are non-substantive because the revisions remove unnecessary punctuation. The revisions to the tables for Nitrogen Dioxide, Ozone, and Sulfur Dioxide expand the applicability of these NAAQS from Chapter 9, which addresses Administrative Permit Amendments, to include all chapters in Reg. 19. We find these revisions approvable.
**D. Ministerial Changes to the CFR**
We are making ministerial changes to the CFR to reflect that (1) our March 4, 2015 approval of revisions to the Arkansas PSD regulations for the PM <sub>2.5</sub> NAAQS (80 FR 11573) addressed our August 20, 2012 disapproval of Arkansas infrastructure SIP elements pertaining to these NAAQS (77 FR 50033) and (2) our approval of the revised definition for “CO2 equivalent emissions” submitted on March 24, 2017 addresses our May 23, 2016 disapproval of the definition (81 FR 32239), as described in paragraph *B* of this action and the TSD.
**E. Section 110(l) Analysis**
Section 110(l) of the Act precludes EPA from approving a revision of a plan if the revision would interfere with any applicable requirement concerning attainment and reasonable further progress (as defined in section 171 of the CAA), or any other applicable requirement of the Act. The submitted revisions in this action expand the applicability of the NAAQS in Appendix B to all chapters in Reg. 19. In addition, the submitted revisions evaluated in this action do not relax or otherwise weaken existing rules in the Arkansas SIP. Therefore, these revisions would not contribute to future violations of the NAAQS or interfere with reasonable further progress or any applicable CAA requirements. The non-substantive revisions also would not contribute to future violations of the NAAQS or interfere with reasonable further progress or any applicable CAA requirements.
**III. Final Action**
Pursuant to section 110 of the CAA, EPA is approving revisions to the Arkansas SIP submitted on March 24, 2017. Specifically, we are approving revisions to Regulation 19, Chapter 1, Sections 101 and 103; Chapter 2 definitions; Chapter 3, Sections 301 and 304; Chapter 5, Sections 502-504; Chapter 13, Sections 1303 and 1308; Chapter 14, Section 1401; Chapter 15, Sections 1502 and 1504; and Appendix B tables addressing Lead, Nitrogen Dioxide, Ozone, PM <sub>10</sub> , and Sulfur Dioxide. The EPA is also removing the disapproval of the Greenhouse Gas (GHG) Biomass Deferral listed at 40 CFR 52.172(c).
The EPA is publishing this rule without prior proposal because we view this as a non-controversial amendment and anticipate no adverse comments. However, in the proposed rules section of this *Federal Register* publication, we are publishing a separate document that will serve as the proposal to approve the SIP revision if relevant adverse comments are received. This rule will be effective on November 6, 2018 without further notice unless we receive relevant adverse comment by September 7, 2018. If we receive relevant adverse comments, we will publish a timely withdrawal in the *Federal Register* informing the public that the rule will not take effect. We will address all public comments in a subsequent final rule based on the proposed rule. We will not institute a second comment period on this action. Any parties interested in commenting must do so now. Please note that if we receive relevant adverse comment on an amendment, paragraph, or section of this rule and if that provision may be severed from the remainder of the rule, we may adopt as final those provisions of the rule that are not the subject of an adverse comment.
**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 of the revisions to the Arkansas regulations as described in the Final Action section above. The EPA has made, and will continue to make, these materials generally available through *www.regulations.gov* and at the EPA Region 6 Office (please contact Carrie Paige, 214-665-6521, *[email protected]* 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 rulemaking of EPA's approval, and will be incorporated by reference in the next update to the SIP compilation.
**V. Statutory and Executive Order Reviews**
Under the CAA, the Administrator is required to approve a SIP submission that complies with the provisions of the Act and applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in reviewing SIP submissions, the EPA's role is to approve state choices, provided that they meet the criteria of the CAA. 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);
• Is not an Executive Order 13771 (82 FR 9339, February 2, 2017) regulatory action because SIP approvals are exempted under Executive Order 12866;
• 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 an economically significant regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997);
• Is not a significant regulatory action subject to Executive Order 13211 (66 FR 28355, May 22, 2001);
• 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 CAA; and
• Does not provide EPA with the discretionary authority to address, as appropriate, disproportionate human health or environmental effects, using practicable and legally permissible methods, under Executive Order 12898 (59 FR 7629, February 16, 1994).
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).
The Congressional Review Act, 5 U.S.C. 801 *et seq.,* as added by the Small Business Regulatory Enforcement Fairness Act of 1996, generally provides that before a rule may take effect, the agency promulgating the rule must submit a rule report, which includes a copy of the rule, to each House of the Congress and to the Comptroller General of the United States. The EPA will submit a report containing this rule and other required information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the United States prior to publication of the rule in the *Federal Register* . A major rule cannot take effect until 60 days after it is published in the *Federal Register* . 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 October 9, 2018. Filing a petition for reconsideration by the Administrator of this final rule does not affect the finality of this rule 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).)
