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

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: Pursuant to the Federal Clean Air Act (CAA or the Act), the 
Environmental Protection Agency (EPA) is proposing to approve 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.

I. Background

    The SIP is a set of air pollution regulations, control strategies, 
and technical analyses developed by the state to implement, maintain, 
and enforce the National Ambient Air Quality Standards, or NAAQS, and 
to fulfill other requirements of the Clean Air Act. The NAAQS 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.
    The Arkansas SIP is the air quality protection strategy implemented 
by the Department of Energy and Environment's Division of Environmental 
Quality (DEQ) pursuant to the CAA. The SIP consists of laws and rules, 
nonregulatory and quasi-regulatory measures, and other state 
enforceable requirements codified at 40 CFR 52 subpart E. The Arkansas 
SIP is federally enforceable. The Arkansas SIP was first approved by 
the EPA in 1972 (37 FR 10841). All revisions to the SIP require EPA 
approval.
    On June 22, 2022, Arkansas submitted to the EPA revisions to the 
Arkansas SIP.\1\ The submitted revisions address APC&EC Regulation 19, 
Rules of the Arkansas Plan of Implementation for Air Pollution Control, 
with corresponding chapters and appendices. The revisions restructure 
the regulations and organize them as rules, such that Regulation 19 
becomes Rule 19, Rules of the Arkansas Plan of Implementation for Air 
Pollution Control, with corresponding chapters and appendices. The 
revisions also remove certain outdated provisions and update other 
provisions that are incorporated into Regulation 19. Specific 
provisions to be 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, provisions for 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.
---------------------------------------------------------------------------

    \1\ The cover letter on the submitted revisions is dated May 12, 
2022, but the submittal package was not submitted to EPA until June 
22, 2022.
---------------------------------------------------------------------------

    Additionally, the submitted revisions address regulatory provisions 
in Chapters 1, 2, 3, 4, 5, 6, 7, 9, 11, 13, 16, 18, and Appendices A 
and B of Regulation 19.\2\ These changes reflect the current 
organizational structure of ADEQ, remove outdated information, and make 
non-substantive formatting edits.
---------------------------------------------------------------------------

    \2\ See accompanying Technical Support Document (TSD) available 
in the docket for this rulemaking.

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

[[Page 57015]]

    The submitted revisions to Chapter 10 also address an EPA-
identified deficiency within the Arkansas SIP related to the 2015 
Startup, Shutdown, and Malfunction (SSM) SIP Call for Regulation. 
19.1004(H).\3\ The EPA plans to address this matter in a separate 
Federal Register action.
---------------------------------------------------------------------------

    \3\ See ``State Implementation Plans: Response to Petition for 
Rulemaking; Restatement and Update of EPA's SSM Policy Applicable to 
SIPs; Findings of Substantial Inadequacy; and SIP Calls To Amend 
Provisions Applying to Excess Emissions During Periods of Startup, 
Shutdown and Malfunction,'' (80 FR 33839, June 12, 2015).
---------------------------------------------------------------------------

II. The EPA's Evaluation

A. Regulation 19, Chapter 10--Control of VOCs in Pulaski County

    These rules address Pulaski County because in March 1978, the EPA 
designated Pulaski County, Arkansas, as a nonattainment area for ozone 
(43 FR 8969, March 3, 1978). Pulaski County subsequently met the ozone 
NAAQS and in September 1984, the EPA approved the State's request to 
redesignate Pulaski County to attainment (49 FR 37753, September 26, 
1984). Since redesignation, Pulaski County has maintained compliance 
with all the ozone NAAQS. In this action, we are proposing to approve 
revisions to Regulation 19.1001 and 19.1002 which are non-substantive. 
We are also proposing to approve the submitted revisions to 19.1003 
through 19.1006. Although the submitted revisions to 19.1003 through 
19.1006 are substantive in nature, they are superseded by more 
stringent federal requirements. VOC emissions are not expected to 
increase because existing and new sources subject to Chapter 10 in 
Pulaski County are subject to the more stringent federal requirements 
for New Source Performance Standards (NSPS) and National Emission 
Standards for Hazardous Air Pollutants (NESHAP). The EPA's analysis of 
the submitted revisions, and confirmation that VOC emissions will not 
increase, is included in the TSD for this action. As a result, 
consistent with CAA section 110(l), we do not expect these revisions to 
interfere with any applicable requirement concerning attainment and 
reasonable further progress or any other applicable requirement of the 
Act.

B. Regulation 19, Chapter 14--CAIR Requirements

    Provisions for the CAIR NOX Ozone Season Trading Program 
were approved into the Arkansas SIP on September 26, 2007 (72 FR 
54556).\4\ On July 11, 2008, the U.S. Court of Appeals for the District 
of Columbia vacated and remanded the CAIR program to the EPA. The 
submitted revisions include the repeal of the Regulation 19, Chapter 14 
CAIR provisions consistent with the court's decision. This revision is 
approvable because there are no federal requirements for the Arkansas 
SIP or sources in Arkansas to continue complying with the CAIR 
NOX Ozone Season Trading Program or the provisions in Rule, 
Chapter 14.
---------------------------------------------------------------------------

    \4\ Oxides of Nitrogen (NOX) and VOC are precursors 
to ozone formation.
---------------------------------------------------------------------------

C. Regulation 19, Chapter 15--Best Available Retrofit Technology

    Arkansas Regulation 19, Chapter 15 was approved by the EPA into the 
SIP on March 12, 2012,\5\ except for certain portions of Regulation 
19.1504 and 19.1505. The submitted revisions address Regulation 
19.1501, 19.1502, 19.1503, 19.1504, 19.1505, 19.1506, and 19.1507. We 
are proposing to approve these revisions because they fall into one or 
more of the following categories: (1) the revisions are non-substantive 
and/or are formatting edits; (2) the revisions improve the readability 
of the provision; (3) the revisions repeal provisions that do not 
contain enforceable requirements and as a result are not required to be 
part of the SIP; or (4) the revisions repeal provisions that are not in 
the approved SIP. The revisions to Chapter 15 do not repeal or relax 
any existing control requirements in the SIP and therefore the EPA does 
not anticipate any emission increases associated with the revisions to 
Chapter 15. Consistent with CAA section 110(l), we do not expect these 
revisions to interfere with any applicable requirement concerning 
attainment and reasonable further progress or any other applicable 
requirement of the Act. We provide our analysis of the submitted 
revisions to Chapter 15 in the paragraphs that follow.
---------------------------------------------------------------------------

    \5\ See 77 FR 14603 (March 12, 2012).
---------------------------------------------------------------------------

Regulation 19.1501 ``Purpose''
    Regulation 19.1501 states the purpose of Regulation 19, Chapter 15, 
but does not contain enforceable requirements. The submitted revisions 
to Regulation 19.1501 provide a more precise description of the purpose 
of Chapter 15. Therefore, we are proposing to approve these submitted 
revisions to Regulation 19.1501.
Regulation 19.1502 ``Definitions''
    The submitted revisions to Regulation 19.1502 are non-substantive 
formatting edits. We are proposing to approve the submitted revisions 
to Regulation 19.1502.
Regulation 19.1503 ``BART Eligible Sources''
    Arkansas Regulation 19.1503 identifies the BART-eligible sources 
within the State. The submitted revision to Regulation 19.1503 repeals 
the provision in its entirety and places the subsection in reserve. 
Arkansas explained in Appendix A of the submitted revisions that 
Regulation 19.1503 consists of an informational table that does not 
contain enforceable requirements and is not necessary to identify the 
sources subject to the requirements of Chapter 15 that are in the SIP, 
as identified in Rule 19.1505.\6\ Furthermore, the informational table 
in Rule 19.1503 is also contained in the SIP submittal narrative for 
the Arkansas Regional Haze Planning Period 1, Phase II SIP revision, 
which the EPA previously approved.\7\ The repeal of Regulation 19.1503 
does not change the State's determination of BART-eligible sources in 
Arkansas. Thus, we are proposing to approve the submitted revision to 
Regulation 19.1503.
---------------------------------------------------------------------------

    \6\ See ``Appendix A: Technical Support Document, Changes to the 
Rules of the State Implementation Plan,'' pages 5-6. Appendix A is 
part of the submitted revisions and is found in the docket for this 
proposed rulemaking.
    \7\ See 84 FR 51033 (September 27, 2019).
---------------------------------------------------------------------------

Regulation 19.1504 ``Facilities Subject to BART''
    Regulation 19.1504 consists of Regulation 19.1504(A), (B), and (C). 
The submitted revisions to Regulation 19.1504 repeal and move 
provisions and place the subsection in reserve. The submitted revisions 
repeal Regulation 19.1504(A) and move the provisions of Regulation 
19.1504(B) and (C) to Regulation 19.1506 with edits to the language.
    Arkansas explained in Appendix A of the submitted revisions that 
Regulation 19.1504(A) consists of an informational table that 
identifies the sources in Arkansas that are subject to BART but the 
table itself does not contain any enforceable requirements.\8\ 
Regulation 19.1504(A) is not necessary to identify the sources subject 
to the requirements of Chapter 15 that are in the SIP, as those sources 
are identified in Regulation 19.1505.\9\ Furthermore, the informational 
table in Regulation 19.1504(A) is also contained in the SIP submittal 
narrative for the Arkansas Regional Haze Planning Period 1, Phase II 
SIP revision, which the EPA approved

[[Page 57016]]

in a final rule.\10\ Thus, the repeal of Regulation 19.1504(A) does not 
change the State's determination of subject-to-BART sources in 
Arkansas. We are proposing to approve the revision to Regulation 
19.1504(A).
---------------------------------------------------------------------------

    \8\ ``Appendix A: Technical Support Document, Changes to the 
Rules of the State Implementation Plan,'' pages 5-6. Appendix A is 
part of the submitted revision and is found in the docket for this 
proposed rulemaking.
    \9\ Ibid.
    \10\ See 84 FR 51033 (September 27, 2019).
---------------------------------------------------------------------------

    Regulation 19.1504(B) contains BART compliance date requirements. 
The submitted revisions to Regulation 19.1504(B) move Regulation 
19.1504(B) to Regulation 19.1506(A) with non-substantive revisions to 
the language and deletion of the portion not in the approved SIP.\11\ 
Regulation 19.1504(C) contains provisions requiring sources subject to 
BART to maintain the control equipment required by Chapter 15 and to 
establish procedures to ensure such equipment is properly operated and 
maintained. The submitted revisions to Regulation 19.1504(C) move these 
provisions to Regulation 19.1506(B) and (C) with non-substantive 
revisions to the language. Moving the provisions in Rule 19.1504(B) and 
(C) to Rule 19.1506(A), (B) and (C) results in the consolidation of the 
compliance provisions for sources subject to the requirements of 
Chapter 15. For these reasons, we are proposing to approve the 
revisions to Regulation 19.1504(B) and (C).
---------------------------------------------------------------------------

    \11\ Only a portion of Rule 19.1504(B) is in the approved SIP. 
This portion is the requirement for each source subject to BART to 
install and operate BART as expeditiously as practicable, but in no 
event later than 5 years after the EPA approval of that source's 
BART determination. (See 77 FR 14604, 14675, March 12, 2012).
---------------------------------------------------------------------------

Regulation 19.1505 ``Best Available Retrofit Technology Requirements''
    Arkansas Regulation 19.1505 consists of BART emission limits for 
subject-to-BART sources in Arkansas that are subject to the 
requirements of Chapter 15. The submitted revisions make a minor 
amendment to the title of Regulation 19.1505, remove all provisions 
that are not currently in the approved SIP,\12\ and restructure and 
make other non-substantive edits to the provisions in the approved SIP. 
Because of our prior disapproval,\13\ the following provisions were 
never approved into the Arkansas SIP and thus, the State's removal of 
this language from its State rules is a non-substantive change: 
Regulation 19.1505(A)(1) and (A)(2); 19.1505(B); 19.1505(C); 
19.1505(D)(1) and (D)(2); 19.1505(E)(1), (E)(2), and (E)(3); 
19.1505(F)(1) and (F)(2); 19.1505(G)(1) and (G)(2); 19.1505(H); 
19.1505(I)(1) and (I)(2); 19.1505(J)(1) and (J)(2); 19.1505(K); 
19.1505(L); 19.1505(M)(1); and 19.1505(N)(1), (N)(2), and (N)(3). 
Because these submitted revisions delete previously disapproved 
language, we are proposing to remove our prior disapproval of the 
provisions of Regulation 19.1505 (77 FR 14604).
---------------------------------------------------------------------------

    \12\ 77 FR 14604, 14675.
    \13\ 77 FR 14604, 14675.
---------------------------------------------------------------------------

    The submitted revisions also remove Regulation 19.1505(D)(3). This 
provision was approved by the EPA at 77 FR 14604, and therefore, the 
repeal of Regulation 19.1505(D)(3) is a substantive change. In a final 
rule published on March 22, 2021, we approved BART alternative 
requirements under 40 CFR 51.308(e)(2) that replaced the provision 
under Regulation 19.1505(D)(3).\14\ Therefore, the repeal of Regulation 
19.1503(D)(3) does not relax any existing requirements in the SIP. In 
fact, it is necessary for Arkansas to remove Regulation 19.1505(D)(3) 
from its State rules and the SIP given that the BART requirements 
contained in Regulation 19.1505(D)(3) have been replaced.\15\ For this 
reason, we are proposing to approve the submitted revision to repeal 
Regulation 19.1505(D)(3).
---------------------------------------------------------------------------

    \14\ The EPA finalized approval of the State's withdrawal of the 
PM10 BART determination of 0.07 lb/MMBtu for Ashdown Mill #1 Power 
Boiler, SN-03 and approved its replacement with the PM10 BART 
alternative limit in the Arkansas Regional Haze Phase III SIP 
submittal (See 86 FR 15104, 15130, March 22, 2021).
    \15\ The current BART requirements approved in the SIP for 
Domtar Ashdown Mill #1 Power Boiler, SN-03 are found in Permit 
#0287-AOP-R22. (See 86 FR at 15131).
---------------------------------------------------------------------------

    The submitted revisions also restructure some of the remaining 
provisions under Regulation 19.1505, which results in greater clarity 
and concision of those provisions. Therefore, we are proposing to 
approve these revisions.
Regulation 19.1506 ``Compliance Provisions''
    Regulation 19.1506 consists of compliance provisions for sources 
subject to the requirements of Chapter 15. The submitted revisions 
update and consolidate the compliance requirements that were previously 
in Regulation 19.1504(B) \16\ and (C) with edits that are non-
substantive. For these reasons, we are proposing to approve the 
submitted revisions to Regulation 19.1506.
---------------------------------------------------------------------------

    \16\ As discussed earlier, only a portion of Regulation 
19.1504(B) is in the approved SIP.
---------------------------------------------------------------------------

Regulation 19.1507 ``Permit Reopening''
    Regulation 19.1507 is a provision that makes subject-to-BART 
sources subject to reopening of their permit to incorporate the 
requirements of Regulation 19.1505. The submitted revision to 
Regulation 19.1507 repeals the provision in its entirety and places the 
subsection in reserve. Although the revision is substantive, it does 
not relax any existing requirements in the SIP. Arkansas explained in 
Appendix A of the submitted revisions that this provision is no longer 
relevant as the only requirements that remain in Regulation 19.1505 are 
based on existing permit conditions.\17\ For this reason, we are 
proposing to approve the submitted revision to Regulation 19.1507.
---------------------------------------------------------------------------

    \17\ See ``Appendix A: Technical Support Document, Changes to 
the Rules of the State Implementation Plan,'' page 6. Appendix A is 
part of the Arkansas SIP submittal dated May 12, 2022 and is found 
in the docket for this proposed rulemaking.
---------------------------------------------------------------------------

D. CAA Section 110(l) Evaluation

    The submitted revisions to Regulation 19 add clarity, consistency, 
and overall strengthen the Arkansas SIP. The revisions do not relax the 
current SIP approved rules and are consistent with Federal regulations. 
Therefore, and consistent with CAA section 110(l), we do not expect 
these revisions to interfere with any applicable requirement concerning 
attainment and reasonable further progress or any other applicable 
requirement of the Act.

III. Proposed Action

    For the reasons described in this action and in the TSD, we are 
proposing to approve a portion of revisions to the Arkansas SIP 
submitted on June 22, 2022. Specifically, we are proposing to approve 
the following submitted revisions to Regulation 19: renaming Regulation 
19 as Rule 19; revisions to Chapters 1, 2, 3, 4, 5, 6, 7, 9, 11, 13, 
15, and Appendices A and B of Regulation 19. We are also proposing to 
approve 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. We are proposing to approve these revisions in 
accordance with section 110 of the Act.

IV. Environmental Justice Considerations

    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 results of this analysis are being provided for information 
and transparency purposes. The results of the demographic analysis 
indicate that that for populations living within Pulaski County, the 
percent people of color (persons who reported their race

[[Page 57017]]

as a category other than white alone (not Hispanic or Latino)) is above 
the national average for Pulaski County; and below the national average 
for the State of Arkansas as a whole (49.3 and 28.7 percent, 
respectively versus 40.7 percent). Within people of color, the percent 
of the population that is Black or African American alone is 
significantly above the national average for Pulaski County and above 
the national average for the State as a whole (38.3 and 15.7 percent, 
respectively versus 13.6 percent), and the percent of the population 
that is American Indian/Alaska Native is below the national average for 
both Pulaski County and the State as a whole (0.5 and 1.1 percent, 
respectively versus 1.3 percent).
    This proposed action revises portions of the Arkansas SIP including 
revisions to Rule 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 proposed revisions will 
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.

V. Incorporation by Reference

    In this action, we are proposing to include in a final rule 
regulatory text that includes incorporation by reference. In accordance 
with the requirements of 1 CFR 51.5, we are proposing to incorporate by 
reference revisions to the Arkansas regulations as described in 
Sections II, The EPA's Evaluation, and III, Proposed Action, of this 
preamble. These state regulations contain the air pollution control 
provisions for the State of Arkansas. We have made, and will continue 
to make, these documents generally available electronically through 
www.regulations.gov (please contact the person identified in the FOR 
FURTHER INFORMATION CONTACT section of this preamble for more 
information).

VI. 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 proposes to approve 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);
     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.
    In addition, the SIP is not approved to apply on any Indian 
reservation land or in any other area where the EPA or an Indian tribe 
has demonstrated that a tribe has jurisdiction. In those areas of 
Indian country, the proposed 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).
    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. 
The 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.'' \18\ The 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.'' \19\

    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 
EJ analysis, as is described earlier 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 EJ for people of color, low-income populations, and 
Indigenous peoples.
