Air Plan Approval; Arkansas; Revisions to State Implementation 
Plan Permitting Programs

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 revisions 
to the Arkansas State Implementation Plan (SIP) Permitting Programs 
submitted on October 24, 2002, July 26, 2010, November 6, 2012, and 
March 24, 2017. Most of the revisions are administrative in nature and 
make the SIP current with Federal rules. In addition, the revisions add 
permit flexibility provisions to the NSR program. This proposed action 
is consistent with the requirements of section 110 of the CAA.

DATES: Written comments must be received on or before July 1, 2019.

ADDRESSES: Submit your comments, identified by Docket No. EPA-R06-OAR-

I. Background

    The EPA is proposing approval of SIP revisions submitted by 
Arkansas on October 24, 2002, July 26, 2010, November 6, 2012, and 
March 24, 2017. The proposed revisions addressed in this action include 
administrative revisions, revisions that make the Arkansas SIP current 
with Federal rules, and revisions that add permit flexibility 
provisions to the NSR program. Also, included in this action is the 
proposed approval of revisions to the Arkansas SIP that address EPA's 
previous 2016 disapproval related to biomass deferral language. The 
specific provisions addressed in this action are discussed below.

A. October 24, 2002 Submittal

    On October 24, 2002, Arkansas submitted revisions to the SIP that 
included changes enacted at Reg. 26, Chapters 3, 4, and 6. These 
revisions were adopted by the Arkansas Pollution Control & Ecology 
Commission on August 23, 2002, and became effective on September 26, 
2002.
    This action is the EPA's first action on the October 24, 2002 SIP 
revision

[[Page 25219]]

submittal and will address all of the SIP revisions to Reg. 26, 
Chapters 3, 4, and 6 contained in the 2002 submittal.

B. July 26, 2010 Submittal

    On July 26, 2010, Arkansas submitted revisions to the SIP that 
included changes enacted at Reg. 19, Chapters 1, 2, 3, 4, 5, 6, 7, 9, 
10, 11, 13, 14, 15, and Appendix A and enacted at Reg. 26, Chapters 3, 
4, 5, and 6. These revisions were adopted by the Arkansas Pollution 
Control & Ecology Commission on December 5, 2008, and became effective 
on January 25, 2009. (On November 23, 2010, Teresa Marks, Director of 
the Arkansas Department of Environmental Quality (ADEQ), provided a 
clarification letter regarding the July 26, 2010 submittal. This 
clarification letter was a resubmission of the SIP revision resulting 
from the previous submittal containing one incorrect hardcopy and 
electronic copy of the SIP revision.) On March 28, 2019, Arkansas 
withdrew a portion of the July 26, 2010 submitted revisions from 
consideration for approval into the Arkansas SIP. Therefore, EPA is not 
taking action on those withdrawn revisions, as they are no longer in 
front of EPA for review.\1\
---------------------------------------------------------------------------

    \1\ Arkansas withdrew the following revisions from the July 26, 
2010 submittal in their March 28, 2019 request for withdrawal: 
Changes to Reg. 19.407(B)(1)(b).
---------------------------------------------------------------------------

    The EPA is proposing to take action only on the revisions to Reg. 
19, Chapter 4, Sections 405, 411, 414, 415, and 416; Reg. 19, Appendix 
A; Reg. 26, Chapter 3, Sections 301 and 302; Reg. 26, Chapter 4, 
Sections 401, 402, 407, 409, and 410; Reg. 26, Chapter 5, Sections 501 
and 502; and Reg. 26, Chapter 6, Sections 601, 602, 603, and 604. The 
July 26, 2010 submittal also contained the replacement of ``Sections'' 
with ``Reg.'' throughout Reg. 19 and Reg. 26 section headings (e.g., 
``Section 26.101'' heading revised to ``Reg. 26.101''). We are 
proposing to approve this non-substantive change throughout the current 
SIP-approved portions of Reg. 19 and Reg. 26. The EPA has already taken 
action on other elements of this submittal as follows: (1) EPA approved 
revisions to Reg. 19, Chapter 15 on March 12, 2012 (77 FR 14604); (2) 
EPA approved revisions to Reg. 19, Chapter 9 on April 2, 2013 (78 FR 
19596); (3) EPA approved revisions to Reg. 19, Chapter 14 on April 17, 
2014 (78 FR 21631); (4) EPA approved revisions to Reg. 19, Chapters 1, 
2, 3, 5, 6, 7, 10, 11, and 13 on March 4, 2015 (80 FR 11573); and (5) 
EPA approved a portion of the revisions to Reg. 19, Chapter 4 on June 
29, 2018 (83 FR 30553).

C. November 6, 2012 Submittal

    On November 6, 2012, Arkansas submitted revisions to the SIP that 
included changes enacted at Reg. 19, Chapters 1, 2, 3, 5, 9 and 
Appendix A and enacted at Reg. 26, Chapter 4. These revisions were 
adopted by the Arkansas Pollution Control & Ecology Commission on June 
22, 2012, and October 26, 2012, and became effective on July 9, 2012, 
and November 18, 2012, respectively. On March 28, 2019, Arkansas 
withdrew a portion of the November 6, 2012 submitted revisions from 
consideration for approval into the Arkansas SIP. Therefore, EPA is not 
taking action on those withdrawn revisions, as they are no longer 
before EPA for review.\2\ In addition, EPA returned a portion of the 
November 6, 2012 submitted revisions back to Arkansas because they were 
no longer applicable as a result of the March 28, 2019 withdrawal 
request. EPA is not taking action those returned revisions, as they are 
no longer in front of EPA for review.\3\
---------------------------------------------------------------------------

    \2\ Arkansas withdrew the following revisions from the November 
6, 2012 submittal in their March 28, 2019 request for withdrawal: 
Changes to Reg. 19.405(B)(1); changes to Reg. 19.407(C)(3); changes 
to Reg. 19, Appendix A, Group A, Item 1; and the addition of 
``75,000 tpy carbon dioxide'' to Reg. 19, Appendix A, Group A, Item 
13.
    \3\ As a result of Arkansas's March 28, 2019 withdrawal request, 
the revisions to 407(B)(1)(b) submitted on November 6, 2012 were no 
longer applicable and were returned to the state on May 21, 2019.
---------------------------------------------------------------------------

    The EPA is proposing to take action only on the revisions to Reg. 
19, Chapter 4, Section 407; Reg. 19, Appendix A; and Reg. 26, Chapter 
4, Section 401. The EPA has already taken action on other elements of 
this submittal as follows: (1) EPA approved revisions to Reg. 19, 
Chapter 9 on April 2, 2013 (78 FR 19596); (2) EPA approved revisions to 
Reg. 19, Chapters 1 and 2 on March 4, 2015 (80 FR 11573); and (3) EPA 
approved revisions to Reg. 9, Chapters 1, 2, 3, 5, and 9 on April 30, 
2015 (80 FR 24216).

D. March 24, 2017 Submittal

    On March 24, 2017, Arkansas submitted revisions to the SIP that 
included changes enacted at Reg. 19, Chapters 1, 2, 3, 4, 5, 7, 9, 11, 
13, 14, 15, Appendix A, and Appendix B and enacted at Reg. 26, Chapters 
3, 4, 5, and 6, as well as, the submittal of Infrastructure and NAAQS 
SIPs. These revisions were adopted by the Arkansas Pollution Control & 
Ecology Commission on February 26, 2016, and became effective on March 
14, 2016.
    The EPA is proposing to take action only on the revisions to Reg. 
19, Chapter 7, Sections 702 and 703; Reg. 19, Chapter 9, Sections 901, 
903, and 904; Reg. 19, Chapter 11; Reg. 19, Appendix A; Reg. 26, 
Chapter 3, Section 302; Reg. 26, Chapter 4, Sections 401, 402, and 407; 
Reg. 26, Chapter 5, Section 502; and Reg. 26, Chapter 6, Sections 602, 
603, and 604. The EPA has already taken action on other elements of 
this submittal as follows: (1) EPA approved revisions to Reg. 19, 
Chapter 9 on April 2, 2013 (78 FR 19596); (2) EPA approved revisions to 
Reg. 19, Chapters 1 and 2 on March 4, 2015 (80 FR 11573); (3) EPA 
approved revisions to Reg. 9, Chapters 1, 2, 3, 5, and 9 on April 30, 
2015 (80 FR 24216).

II. Summary of Revisions to the Arkansas SIP and EPA's Evaluation

A. Non-Substantive Changes

    Non-substantive changes were made to Regulation 19, Chapter 4, 
Sections 405, 406, 407, 411, 412, and 415; Chapter 7, Sections 702 and 
703; Chapter 9, Sections 901, 903, and 904; Chapter 11; Appendix A and 
Regulation 26, Chapter 3, Section 302; Chapter 4, Sections 401, 402, 
and 407; Chapter 5, Section 502; and Chapter 6, Sections 602, 603, and 
604 such as edits to acronyms, punctuation and section symbols. A 
complete listing of the non-substantive changes is in the TSD for this 
action. In addition, as part of the July 2, 2010 SIP revision 
submittal, section headings were changed from ``Section'' to ``Reg.'' 
throughout Reg. 19 and Reg. 26. We are proposing approval of this non-
substantive change to the SIP-approved portions of Reg. 19 and Reg. 26 
as part of this action. The non-substantive changes are being approved 
here to maintain consistency between State rules and the approved SIP.

B. Updated References to Federal Regulations

    Revisions were made to Regulations 19 and 26 to reflect more recent 
publication and/or effective dates of federal regulations that are 
referenced in the Arkansas SIP. These revisions are found in Regulation 
19, Chapter 4, Sections 407 and 412; Chapter 7, Sections 702 and 703; 
Chapter 9, Section 903 and 904; and Appendix A and Regulation 26, 
Chapter 4, Section 401; and Chapter 6, Sections 603 and 604. The TSD 
for this action includes a complete listing of the revised reference 
dates along with a description of any changes the update version(s) of 
the federal rule contained. These changes are being approved here to 
maintain consistency between State rules and the approved SIP and so 
that the current SIP references the updated federal regulations.

[[Page 25220]]

C. Clarifications to Existing SIP Provisions

    Revisions to provide additional clarification in the regulatory 
language were made to Reg. 19, Section 407 and Reg. 19, Appendix A. 
These changes were made to ensure consistency within the regulatory 
provisions of Reg. 19 and to make the existing requirements clearer 
within the regulatory language itself. The TSD for this action denotes 
the revisions made to the regulatory text and details regarding the 
basis for the revisions. EPA does not believe that the approval of the 
revisions made to provide additional clarification impact the 
regulations ability to meet the applicable CAA requirements for the 
Arkansas SIP, including non-interference with attainment.

D. Revisions To Address EPA's Previous Disapproval

    EPA's final rulemaking effective June 22, 2016, disapproved 
severable portions of the Arkansas SIP submittal dated November 6, 2012 
that adopted the Biomass Deferral because they were no longer 
consistent with federal laws and regulations (81 FR 32239). In response 
to EPA's 2016 final rulemaking, Arkansas adopted subsequent revisions 
to address the disapproval and remove the previously adopted biomass 
deferral language at Reg. 19.904(G)(2)(b). In this action, EPA is 
proposing to approve these revisions to the Arkansas SIP that address 
our 2016 disapproval.

E. Permit Flexibility Provisions--Regulation 19.414, 19.415, and 19.416

    Arkansas submitted the permit flexibility provisions found in Reg. 
19.414, 415, and 416 for incorporation into the Arkansas SIP. As 
discussed in this section, EPA finds that the revisions to add these 
provisions into the SIP are approvable.
    Reg. 19.414--Operational Flexibility-Applicant's Duty to Apply for 
Alternative Scenarios, allows permittees to implement alternative 
scenarios that were initially included in their permit application, 
without a permit revision or notification to the Department. These 
alternative scenarios underwent review by the Department and were 
included, along with any associated requirements (e.g., monitoring, 
recordkeeping, and reporting requirements), in the permit that 
underwent public review prior to issuance. Section 110(l) is met 
because the Department's review is required by the SIP's permitting 
rules at Reg. 19.402 and 19.405(A) to ensure that the applicable 
requirements, which include a demonstration that there will be no 
interference with attainment and reasonable further progress and any 
other applicable requirement of the Federal CAA, are met for each 
scenario. As such, approval of the SIP revisions incorporating Reg. 
19.414 does not impact the SIP's ability to continuing meeting the 
applicable requirements since the underlying permitting process through 
which the alternative scenarios are reviewed, approved, and 
incorporated into the permit is a SIP-approved process. EPA finds that 
the approval of Reg. 19.414 into the Arkansas SIP will satisfy the 
requirements of Section 110(l) to not interfere with applicable 
requirements concerning attainment or other applicable CAA SIP 
requirements.
    Reg. 19.415--Changes Resulting in No Emissions Increases, allows 
permittees to make certain changes within the facility that otherwise 
contravene permit terms without a permit revision if the changes are 
not modifications under Title I, do not exceed emissions allowed under 
the permit, do not violate applicable requirements, and do not 
contravene federally enforceable permit terms and conditions that are 
monitoring, recordkeeping, reporting, or compliance certification 
requirements. Pursuant to Reg. 19.415(C), these provisions cannot be 
used to violate applicable requirements, which would include the 
circumvention of state or federal permitting requirements and cannot be 
used for changes that result in emission increases beyond short-term or 
long-term permitted limits, which were determined to be protective of 
the NAAQS by ADEQ during permit issuance. Reg. 19.415(D) also prohibits 
any changes that would contravene federally enforceable permit limits, 
which would include any applicable SIP requirements. ADEQ has indicated 
that they would deny any request pursuant to Reg. 19.415 that violates 
a state or federal permit or permitting requirement.\4\ Section 110(l) 
is met because Reg. 19.415 prohibits changes that circumvent applicable 
state and federal permitting requirements, including those contained in 
the SIP, and does not allow for increases in emissions beyond 
permitting limits that were determined during the SIP-approved 
permitting process to not cause or contribute to a violation of the 
NAAQS. EPA finds that the approval of Reg. 19.415 into the Arkansas SIP 
will not interfere with applicable requirements concerning attainment 
or other applicable CAA SIP requirements.
---------------------------------------------------------------------------

    \4\ Clarification letter dated March 11, 2019, addressed to Ms. 
Adina Wiley, EPA Region 6, from Mr. Thomas Rheaume, ADEQ.
---------------------------------------------------------------------------

    Reg. 19.416--Permit Flexibility, codifies ADEQ's discretion to 
grant extensions to testing, compliance or other dates in a permit; to 
grant a request to allow temporary emissions and/or testing that would 
otherwise exceed a limit in a facility's permit; and to allow an 
alternative to monitoring specified in a facility's operating permit. 
Reg. 19.416 cannot be used to circumvent state or federal permitting 
requirements, and it prohibits at Reg. 19.416(A)(2), (B)(2), and (C)(2) 
any changes that would violate federal requirements, which would 
include any applicable SIP requirements. The temporary emissions 
increases allowed under Reg. 19.416 are limited to less than five tons 
of any individual criteria pollutant, one ton of any single hazardous 
air pollutant, and 2.5 tons of any hazardous air pollutant. The 
temporary emissions increases allowed by Reg. 19.416 are at levels that 
would qualify as an insignificant activity under SIP-approved Reg. 19, 
Appendix A, Group A(13) and are expected to have negligible impacts on 
ambient air concentrations and not interfere with the NAAQS. Section 
110(l) is met because Reg. 19.416 prohibits changes that circumvent 
applicable state and federal permitting requirements, including those 
contained in the SIP, and the temporary emissions increases allowed by 
Reg. 19.416 are limited to levels that would not impact compliance with 
the NAAQS. EPA finds that the approval of Reg. 19.416 into the SIP will 
not interfere with applicable requirements concerning attainment or 
other applicable CAA requirements for SIPs.

III. Proposed Action

    We are proposing to approve portions of the revisions to the 
Arkansas SIP submitted on October 24, 2002, July 26, 2010, November 6, 
2012, and March 24, 2017. Specifically, we are proposing to approve the 
following revisions:
     Revisions to Regulation 19, Chapter 4 adopted on December 
5, 2008 (effective January 25, 2009), June 22, 2012 (effective July 9, 
2012), October 26, 2012 (effective November 18, 2012), and February 26, 
2016 (effective March 14, 2016);
     Revisions to Regulation 19, Chapter 7 adopted on February 
26, 2016 (effective March 14, 2016);
     Revisions to Regulation 19, Chapter 9 adopted on February 
26, 2016 (effective March 14, 2016);
     Revisions to Regulation 19, Chapter 11 adopted on February 
26, 2016 (effective March 14, 2016);

[[Page 25221]]

     Revisions to Regulation 19, Appendix A adopted on December 
5, 2008 (effective January 25, 2009), June 22, 2012 (effective July 9, 
2012), October 26, 2012 (effective November 18, 2012), and February 26, 
2016 (effective March 14, 2016);
     Revisions to Regulation 26, Chapter 3 adopted on August 
23, 2002 (effective September 26, 2002), December 5, 2008 (effective 
January 25, 2009), and February 26, 2016 (effective March 14, 2016);
     Revisions to Regulation 26, Chapter 4 adopted on August 
23, 2002 (effective September 26, 2002), December 5, 2008 (effective 
January 25, 2009), June 22, 2012 (effective July 9, 2012), October 26, 
2012 (effective November 18, 2012), and February 26, 2016 (effective 
March 14, 2016);
     Revisions to Regulation 26, Chapter 5 adopted on December 
5, 2008 (effective January 25, 2009) and February 26, 2016 (effective 
March 14, 2016);
     Revisions to Regulation 26, Chapter 6 adopted on August 
23, 2002 (effective September 26, 2002), December 5, 2008 (effective 
January 25, 2009), and February 26, 2016 (effective March 14, 2016); 
and
     Non-substantive revisions throughout the current SIP-
approved portions of Regulation 19 and 26 that replace ``Section'' with 
``Reg.'' within section headings (e.g., ``Section 26.101'' revised to 
``Reg. 26.101'') that were adopted on December 5, 2008 (effective 
January 25, 2009).
    EPA is not proposing any action to be taken on the portions of the 
July 26, 2010 and November 6, 2012 SIP revision submittals that were 
listed in the letter from Arkansas dated March 28, 2019, that requested 
the withdrawal of those revisions from EPA's consideration for approval 
into the Arkansas SIP.

IV. 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 the 
Proposed Action section above. We have made, and will continue to make, 
these documents generally available electronically through 
www.regulations.gov and in hard copy at the EPA Region 6 office (please 
contact the person identified in the FOR FURTHER INFORMATION CONTACT 
section of this preamble for more information).

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 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 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 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).
