What is the background for this action? khammond on DSKJM1Z7X2PROD with PROPOSALS Existing SIP rule(s) requested to be removed from SIP (state effective date) Rule addressed in this TSD and rulemaking This action focuses on the preconstruction permitting requirements for stationary sources, also called New Source Review, in title I of the CAA and the EPA’s implementing regulations addressing the SIP requirements for state NSR programs at 40 CFR part 51, subpart I. The action focuses on two necessary revisions to the ADEQ’s SIP-approved NSR program rules in accordance with changes that the EPA has made to its NSR program rules and provides the EPA’s findings on whether these SIP VerDate Sep<11>2014 15:03 Dec 29, 2023 Jkt 262001 R18–2–101 (except 20) (02/01/2020). R18–2–404 (03/21/2017). revisions submitted by the ADEQ meet federal NSR requirements. Submitted Rule Arizona Administrative Code (A.A.C.) R18–2– 101 (except 20) contains a change to the definition of categorical sources for ‘‘municipal incinerators’’ as compared with the prior version of the rule that is currently included in the Arizona SIP. The ADEQ amended its definition of ‘‘categorical sources’’ to include municipal incinerators capable of charging more than 50 tons of refuse per day, as compared with the previous version of the definition, which applied only to those capable of charging more than 250 tons per day. This change was made to ensure consistency with CAA section 169(a) and federal regulatory requirements related to major NSR applicability for municipal incinerators in the EPA’s regulations governing state Major NSR programs at 40 CFR 51.165– 51.166, as updated by the EPA’s 2021 Error Corrections Rule.1 Submitted Rule A.A.C. R18–2–404 eliminates the ozone interprecursor trading provision that was included in the prior version of the rule that is currently included in the Arizona SIP. This change was made to ensure consistency with the federal rules governing NNSR programs regulating ozone precursors in 40 CFR 51.165, 1 See PO 00000 86 FR 37918, 37922 (July 19, 2021). Frm 00004 Fmt 4702 Sfmt 4702 which were also updated as part of the EPA’s Error Corrections Rule.2 The ADEQ requested that the EPA replace the current SIP-approved versions of R18–2–101 and R18–2–404 with the submitted revised versions. The December 2022 NSR submittal also addresses state NNSR program requirements for the 2015 ozone NAAQS. On October 26, 2015, the EPA issued a final rule revising the NAAQS for ozone, reducing the standards to a level of 0.070 ppm.3 On June 4, 2018, certain portions of Arizona (Yuma and Phoenix-Mesa) were designated and classified as Marginal nonattainment for the 2015 ozone NAAQS.4 This designation of certain portions of Arizona as federal ozone nonattainment areas for the 2015 ozone NAAQS triggered the requirement for the ADEQ to provide a SIP submittal addressing the NNSR program requirements for this NAAQS and classification for sources and areas within its permitting 2 See 86 FR 37918, 37924. CFR 50.19; see 80 FR 65292, 65452–53. 4 83 FR 25776. We note that on October 7, 2022, the EPA issued a final rule determining that while the Yuma nonattainment area attained the 2015 ozone NAAQS, the Phoenix-Mesa nonattainment area failed to attain by the applicable attainment date and therefore would be reclassified as a Moderate nonattainment area for the 2015 ozone NAAQS. 87 FR 60897. 3 40 E:\FR\FM\02JAP1.SGM 02JAP1 Federal Register / Vol. 89, No. 1 / Tuesday, January 2, 2024 / Proposed Rules jurisdiction.5 Therefore, this action also addresses whether the ADEQ’s NNSR program, as revised by the rules in this SIP submittal, satisfies the applicable CAA NNSR program requirements for the 2015 ozone NAAQS for the Marginal classification for sources and areas within its permitting jurisdiction. B. How is the EPA evaluating these rules? The EPA reviewed the December 2022 NSR submittal for compliance with CAA requirements for SIPs in general as set forth in CAA section 110(a)(2), the requirements for state stationary source preconstruction permitting programs in 40 CFR part 51, subpart I, including certain changes made to those rules in the Error Corrections Rule, and the requirements related to SIP revisions in CAA sections 110(l) 6 and 193.7 Our review also evaluated the ADEQ’s NNSR program, as revised by the submitted revised rules, for compliance with the state NNSR program requirements applicable to ozone nonattainment areas with a Marginal classification. C. Do the rules meet the evaluation criteria? With respect to procedural requirements, CAA sections 110(a)(2) and 110(l) require that revisions to a SIP be adopted by the state after reasonable notice and public hearing. Based on our review of the public process documentation included in the December 2022 NSR submittal, we find that the ADEQ has provided sufficient evidence of public notice, opportunity for comment and a public hearing prior to adoption and submittal of the rules to the EPA. We have evaluated the rule revisions in the December 2022 NSR submittal with respect to the CAA requirements for SIPs in general as set forth in CAA section 110(a)(2), the requirements for state stationary source preconstruction permitting programs in 40 CFR part 51, subpart I, including recent changes to the requirements for State stationary source preconstruction permitting programs in 40 CFR part 51, subpart I, made in the EPA’s Error Corrections 5 CAA section 182(a); 40 CFR 51.1314. section 110(l) requires SIP revisions to be subject to reasonable notice and public hearing prior to adoption and submittal by states to the EPA and prohibits the EPA from approving any SIP revision that would interfere with any applicable requirement concerning attainment and reasonable further progress, or any other applicable requirement of the CAA. 7 CAA section 193 prohibits the modification of any SIP-approved control requirement in effect before November 15, 1990 in a nonattainment area, unless the modification ensures equivalent or greater emission reductions of the relevant pollutants. khammond on DSKJM1Z7X2PROD with PROPOSALS 6 CAA VerDate Sep<11>2014 15:03 Dec 29, 2023 Jkt 262001 Rule, as described above, and we find that the submittal satisfies these requirements. In addition, we have evaluated the ADEQ’s NNSR program, as revised by the submitted revised rules, for compliance with the NNSR requirements applicable to ozone nonattainment areas with a Marginal classification, and have determined that this program satisfies the applicable CAA and regulatory requirements for NNSR permit programs under part D of title I of the Act for all relevant ozone NAAQS, specifically including the requirements applicable to areas designated nonattainment for the 2015 ozone NAAQS with a Marginal classification, for the areas and sources within the ADEQ’s permitting jurisdiction. Regarding the additional substantive requirements of CAA sections 110(l) and 193, our action will result in a more stringent SIP, while not relaxing any existing provision contained in the SIP. We have concluded that our action would comply with section 110(l) because our approval of these rules will not interfere with any applicable requirement concerning attainment and reasonable further progress, or any other CAA applicable requirement. In addition, our approval of these rules will not relax any pre-November 15, 1990 requirement in the SIP, and therefore changes to the SIP resulting from this action ensure greater or equivalent emission reductions of the nonattainment pollutants and their precursors in the District; accordingly, we have concluded that our action is consistent with the requirements of CAA section 193. Our TSD contains a more detailed discussion of our analysis of the December 2022 NSR submittal. III. Proposed Action and Public Comment As authorized in section 110(k)(3) of the Act, the EPA is proposing to fully approve the submitted rules into the Arizona SIP because they fulfill all relevant CAA requirements, and to remove the prior version of these rules from the SIP. We have concluded that our approval of the submitted rules would comply with the relevant provisions of CAA sections 110(a)(2), 110(l), 165, 172(c)(5), 173, and 193, and 40 CFR 51.160–51.166. We are also proposing to find that with the submitted rule revisions, the ADEQ’s NSR program satisfies the requirements for the preconstruction review and permitting of major sources and major modifications under part D of title I of the Act for areas designated nonattainment with the 2015 ozone PO 00000 Frm 00005 Fmt 4702 Sfmt 4702 41 NAAQS with a Marginal classification, for the areas and sources within the ADEQ’s permitting jurisdiction. If we finalize this action as proposed, our action will be codified through revisions to 40 CFR 52.220a (Identification of plan-in part). We will accept comments from the public on this proposal until February 1, 2024. IV. Incorporation by Reference In this rule, the EPA is proposing to include in a final EPA rule regulatory text that includes incorporation by reference. In accordance with requirements of 1 CFR 51.5, the EPA is proposing to incorporate by reference the following the ADEQ rules: A.A.C. R18–2–101 (except 20) and R18–2–404, as described in Table 1 of this proposal. These rules are intended to address the CAA’s statutory and regulatory requirements for New Source Review permit programs for major sources emitting nonattainment air pollutants and their precursors under parts C and D of title I of the CAA. The EPA has made, and will continue to make, these materials available through https:// www.regulations.gov and at the EPA Region IX 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 Clean Air Act, 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 Clean Air Act. Accordingly, this proposed 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 proposed 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); • 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.); E:\FR\FM\02JAP1.SGM 02JAP1 42 Federal Register / Vol. 89, No. 1 / Tuesday, January 2, 2024 / Proposed Rules khammond on DSKJM1Z7X2PROD with PROPOSALS • 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); 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, Feb. 16, 1994) (E.O. 12898) directs Federal agencies to identify and address ‘‘disproportionately high and adverse human health or environmental effects’’ of their actions on minority populations VerDate Sep<11>2014 15:03 Dec 29, 2023 Jkt 262001 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.’’ 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.’’ The 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 did not perform an EJ analysis and did not consider EJ in this 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. Consideration of EJ is not required PO 00000 Frm 00006 Fmt 4702 Sfmt 9990 as part of this action, and there is no information in the record 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 the 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).

C. What is the purpose of the submitted rules?

    The purpose of these submitted revisions for the ADEQ's NSR program 
is to update its rules to ensure consistency with certain changes that 
the EPA has made to its NSR program rules, and to address the CAA's 
statutory and regulatory requirements for Nonattainment New Source 
Review (NNSR) permit programs in areas designated nonattainment with 
the 2015 ozone NAAQS with a Marginal classification, for areas and 
sources within the ADEQ's permitting jurisdiction.

II. The EPA's Evaluation

A. What is the background for this action?

    This action focuses on the preconstruction permitting requirements 
for stationary sources, also called New Source Review, in title I of 
the CAA and the EPA's implementing regulations addressing the SIP 
requirements for state NSR programs at 40 CFR part 51, subpart I.
    The action focuses on two necessary revisions to the ADEQ's SIP-
approved NSR program rules in accordance with changes that the EPA has 
made to its NSR program rules and provides the EPA's findings on 
whether these SIP revisions submitted by the ADEQ meet federal NSR 
requirements.
    Submitted Rule Arizona Administrative Code (A.A.C.) R18-2-101 
(except 20) contains a change to the definition of categorical sources 
for ``municipal incinerators'' as compared with the prior version of 
the rule that is currently included in the Arizona SIP. The ADEQ 
amended its definition of ``categorical sources'' to include municipal 
incinerators capable of charging more than 50 tons of refuse per day, 
as compared with the previous version of the definition, which applied 
only to those capable of charging more than 250 tons per day. This 
change was made to ensure consistency with CAA section 169(a) and 
federal regulatory requirements related to major NSR applicability for 
municipal incinerators in the EPA's regulations governing state Major 
NSR programs at 40 CFR 51.165-51.166, as updated by the EPA's 2021 
Error Corrections Rule.\1\
---------------------------------------------------------------------------

    \1\ See 86 FR 37918, 37922 (July 19, 2021).
---------------------------------------------------------------------------

    Submitted Rule A.A.C. R18-2-404 eliminates the ozone interprecursor 
trading provision that was included in the prior version of the rule 
that is currently included in the Arizona SIP. This change was made to 
ensure consistency with the federal rules governing NNSR programs 
regulating ozone precursors in 40 CFR 51.165, which were also updated 
as part of the EPA's Error Corrections Rule.\2\
---------------------------------------------------------------------------

    \2\ See 86 FR 37918, 37924.
---------------------------------------------------------------------------

    The ADEQ requested that the EPA replace the current SIP-approved 
versions of R18-2-101 and R18-2-404 with the submitted revised 
versions.
    The December 2022 NSR submittal also addresses state NNSR program 
requirements for the 2015 ozone NAAQS. On October 26, 2015, the EPA 
issued a final rule revising the NAAQS for ozone, reducing the 
standards to a level of 0.070 ppm.\3\ On June 4, 2018, certain portions 
of Arizona (Yuma and Phoenix-Mesa) were designated and classified as 
Marginal nonattainment for the 2015 ozone NAAQS.\4\ This designation of 
certain portions of Arizona as federal ozone nonattainment areas for 
the 2015 ozone NAAQS triggered the requirement for the ADEQ to provide 
a SIP submittal addressing the NNSR program requirements for this NAAQS 
and classification for sources and areas within its permitting

[[Page 41]]

jurisdiction.\5\ Therefore, this action also addresses whether the 
ADEQ's NNSR program, as revised by the rules in this SIP submittal, 
satisfies the applicable CAA NNSR program requirements for the 2015 
ozone NAAQS for the Marginal classification for sources and areas 
within its permitting jurisdiction.
---------------------------------------------------------------------------

    \3\ 40 CFR 50.19; see 80 FR 65292, 65452-53.
    \4\ 83 FR 25776. We note that on October 7, 2022, the EPA issued 
a final rule determining that while the Yuma nonattainment area 
attained the 2015 ozone NAAQS, the Phoenix-Mesa nonattainment area 
failed to attain by the applicable attainment date and therefore 
would be reclassified as a Moderate nonattainment area for the 2015 
ozone NAAQS. 87 FR 60897.
    \5\ CAA section 182(a); 40 CFR 51.1314.
---------------------------------------------------------------------------

B. How is the EPA evaluating these rules?

    The EPA reviewed the December 2022 NSR submittal for compliance 
with CAA requirements for SIPs in general as set forth in CAA section 
110(a)(2), the requirements for state stationary source preconstruction 
permitting programs in 40 CFR part 51, subpart I, including certain 
changes made to those rules in the Error Corrections Rule, and the 
requirements related to SIP revisions in CAA sections 110(l) \6\ and 
193.\7\ Our review also evaluated the ADEQ's NNSR program, as revised 
by the submitted revised rules, for compliance with the state NNSR 
program requirements applicable to ozone nonattainment areas with a 
Marginal classification.
---------------------------------------------------------------------------

    \6\ CAA section 110(l) requires SIP revisions to be subject to 
reasonable notice and public hearing prior to adoption and submittal 
by states to the EPA and prohibits the EPA from approving any SIP 
revision that would interfere with any applicable requirement 
concerning attainment and reasonable further progress, or any other 
applicable requirement of the CAA.
    \7\ CAA section 193 prohibits the modification of any SIP-
approved control requirement in effect before November 15, 1990 in a 
nonattainment area, unless the modification ensures equivalent or 
greater emission reductions of the relevant pollutants.
---------------------------------------------------------------------------

C. Do the rules meet the evaluation criteria?

    With respect to procedural requirements, CAA sections 110(a)(2) and 
110(l) require that revisions to a SIP be adopted by the state after 
reasonable notice and public hearing. Based on our review of the public 
process documentation included in the December 2022 NSR submittal, we 
find that the ADEQ has provided sufficient evidence of public notice, 
opportunity for comment and a public hearing prior to adoption and 
submittal of the rules to the EPA.
    We have evaluated the rule revisions in the December 2022 NSR 
submittal with respect to the CAA requirements for SIPs in general as 
set forth in CAA section 110(a)(2), the requirements for state 
stationary source preconstruction permitting programs in 40 CFR part 
51, subpart I, including recent changes to the requirements for State 
stationary source preconstruction permitting programs in 40 CFR part 
51, subpart I, made in the EPA's Error Corrections Rule, as described 
above, and we find that the submittal satisfies these requirements. In 
addition, we have evaluated the ADEQ's NNSR program, as revised by the 
submitted revised rules, for compliance with the NNSR requirements 
applicable to ozone nonattainment areas with a Marginal classification, 
and have determined that this program satisfies the applicable CAA and 
regulatory requirements for NNSR permit programs under part D of title 
I of the Act for all relevant ozone NAAQS, specifically including the 
requirements applicable to areas designated nonattainment for the 2015 
ozone NAAQS with a Marginal classification, for the areas and sources 
within the ADEQ's permitting jurisdiction.
    Regarding the additional substantive requirements of CAA sections 
110(l) and 193, our action will result in a more stringent SIP, while 
not relaxing any existing provision contained in the SIP. We have 
concluded that our action would comply with section 110(l) because our 
approval of these rules will not interfere with any applicable 
requirement concerning attainment and reasonable further progress, or 
any other CAA applicable requirement. In addition, our approval of 
these rules will not relax any pre-November 15, 1990 requirement in the 
SIP, and therefore changes to the SIP resulting from this action ensure 
greater or equivalent emission reductions of the nonattainment 
pollutants and their precursors in the District; accordingly, we have 
concluded that our action is consistent with the requirements of CAA 
section 193.
    Our TSD contains a more detailed discussion of our analysis of the 
December 2022 NSR submittal.

III. Proposed Action and Public Comment

    As authorized in section 110(k)(3) of the Act, the EPA is proposing 
to fully approve the submitted rules into the Arizona SIP because they 
fulfill all relevant CAA requirements, and to remove the prior version 
of these rules from the SIP. We have concluded that our approval of the 
submitted rules would comply with the relevant provisions of CAA 
sections 110(a)(2), 110(l), 165, 172(c)(5), 173, and 193, and 40 CFR 
51.160-51.166. We are also proposing to find that with the submitted 
rule revisions, the ADEQ's NSR program satisfies the requirements for 
the preconstruction review and permitting of major sources and major 
modifications under part D of title I of the Act for areas designated 
nonattainment with the 2015 ozone NAAQS with a Marginal classification, 
for the areas and sources within the ADEQ's permitting jurisdiction. If 
we finalize this action as proposed, our action will be codified 
through revisions to 40 CFR 52.220a (Identification of plan-in part).
    We will accept comments from the public on this proposal until 
February 1, 2024.

IV. Incorporation by Reference

    In this rule, the EPA is proposing to include in a final EPA rule 
regulatory text that includes incorporation by reference. In accordance 
with requirements of 1 CFR 51.5, the EPA is proposing to incorporate by 
reference the following the ADEQ rules: A.A.C. R18-2-101 (except 20) 
and R18-2-404, as described in Table 1 of this proposal. These rules 
are intended to address the CAA's statutory and regulatory requirements 
for New Source Review permit programs for major sources emitting 
nonattainment air pollutants and their precursors under parts C and D 
of title I of the CAA. The EPA has made, and will continue to make, 
these materials available through https://www.regulations.gov and at 
the EPA Region IX 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 Clean Air Act, 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 Clean Air Act. 
Accordingly, this proposed 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 
proposed 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);
     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.);

[[Page 42]]

     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); 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, 
Feb. 16, 1994) (E.O. 12898) 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.'' 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.''
    The 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 
did not perform an EJ analysis and did not consider EJ in this 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. Consideration of EJ is not required as part of this 
action, and there is no information in the record 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 the 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).
