[EPA-R06-OAR-2022-0907; FRL-11174-02-R6]


Air Plan Approval; Arkansas; Revisions to Rule 19 of the Arkansas 
Plan

AGENCY: Environmental Protection Agency (EPA).

ACTION: 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) including 
revisions to the Arkansas Pollution Control and Ecology Commission's 
(``Commission'' or APC&EC) Rule 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 
(DEQ) via the Arkansas Governor's Office on June 22, 2022. Most of the 
revisions are administrative in nature and make the SIP current with 
Federal rules.

DATES: This rule is effective on January 29, 2024.

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certain outdated provisions and update other provisions that are 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repealed are those in Chapter 10 of APC&EC Regulation 19 regarding the 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categories in Pulaski County, and provisions repealed from the Clean 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the repealed provisions were either superseded by other rules or 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

[[Page 90122]]

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:
    <bullet> 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);
    <bullet> Does not impose an information collection burden under the 
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
    <bullet> 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.);
    <bullet> 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);
    <bullet> Does not have federalism implications as specified in 
Executive Order 13132 (64 FR 43255, August 10, 1999);
    <bullet> Is not subject to Executive Order 13045 (62 FR 19885, 
April 23, 1997) because it approves a state program;
    <bullet> Is not a significant regulatory action subject to 
Executive Order 13211 (66 FR 28355, May 22, 2001); and
    <bullet> 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\

---------------------------------------------------------------------------

    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

[[Page 90123]]

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).)
