[EPA-R09-OAR-2020-0352; FRL-9463-01-R9]


Approval of Arizona State Implementation Plan Revisions; Maricopa 
County Air Quality Department; Stationary Source Permits; New Source 
Review

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is taking final 
action to approve revisions to the Maricopa County Air Quality 
Department's (MCAQD or Department) portion of the state implementation 
plan (SIP) for the State of Arizona. We are finalizing full approval of 
six MCAQD rules for the Department's New Source Review (NSR) 
preconstruction permitting program for new and modified stationary 
sources of air pollution under the Clean Air Act (CAA or the Act). The 
revisions update the MCAQD's NSR permitting program for new and 
modified sources of air pollution.

DATES: This rule is effective on March 17, 2022.

I. Proposed Action

    On February 23, 2021, the EPA proposed to approve the rules listed 
in Table 1 for incorporation into the Arizona SIP. See 86 FR 10903. 
Although MCAQD Rule 230 was included in the December 20, 2019 SIP 
Submittal, and the EPA proposed approval in the February 23, 2021 
action, we are deferring action on Rule 230 at this time. Therefore, 
except for Rule 230, the rules listed in Table 1 constitute the MCAQD's 
EPA-approved air quality preconstruction NSR permit program.

----------------------------------------------------------------------------------------------------------------
* The EPA is deferring action on Rule 230 at this time.

    We proposed to approve these rules as part of the MCAQD's general 
and major source NSR permitting programs because we determined that 
these rules

[[Page 8419]]

satisfy the substantive statutory and regulatory requirements for NSR 
permit programs as contained in (1) part C of title I (section 165) of 
the Act for Prevention of Significant Deterioration (PSD) program; (2) 
part D of title I (sections 172 and 173) of the Act for the 
nonattainment NSR program; (3) section 110(a)(2) of the Act for the 
general permitting requirements; (4) sections 110(l) and 193 of the Act 
for SIP revisions and the general savings clause; (5) the regulatory 
provisions in 40 CFR part 51, subpart I (Review of New Sources and 
Modifications) (40 CFR 51.160-51.166); and (6) subpart P (Protection of 
Visibility) (40 CFR 51.307).
---------------------------------------------------------------------------

    \1\ Rule 210 also contains provisions to address requirements 
under title V of the Act for operating permit programs, but we are 
not evaluating the rule for title V purposes at this time. We will 
evaluate Rule 210 for compliance with the requirements of title V of 
the Act and the EPA's implementing regulations in 40 CFR part 70 
following receipt of an official part 70 program revision submittal 
from Maricopa County.
---------------------------------------------------------------------------

    We also proposed to approve these rules because we determined that 
they address the deficiencies identified in our conditional approval of 
Rules 100 and 200 in the EPA's April 5, 2019 action. See 84 FR 13543. 
Finally, we proposed that the rules listed in Table 1 will replace the 
SIP-approved NSR program rules listed in Table 2, in their entirety.

II. Public Comments and EPA Responses

    The EPA's February 23, 2021 proposed rulemaking provided a 30-day 
public comment period. We received comments from the Arizona Center for 
Law in the Public Interest (ACLPI). The full text of the ACLPI's public 
comments is available in the docket for this rulemaking. The EPA's 
summaries of, and responses to, these public comments are as follows:

A. Exemption for Agricultural Equipment Used in Normal Farm Operations 
in Rule 200

    Comment: The commenter states that the MCAQD has failed to identify 
the types of equipment that it considers to be ``agricultural equipment 
used in normal farm operations'' and that ``fugitive emissions'' are 
not a type of ``activity'' or ``equipment.'' The commenter states that 
the MCAQD's exemption for agricultural equipment used in normal farm 
operations is vague to the point of unenforceability. The commenter 
states that this vagueness prevents scrutiny of whether the fugitive 
emissions are actually fugitive (i.e., could not reasonably pass 
through a stack, chimney, vent, or other functionally equivalent 
opening).
    Response: The EPA respectfully disagrees with this comment. In our 
proposed rulemaking for the June 11, 2018 conditional approval action, 
the EPA stated that the MCAQD must provide a basis consistent with 40 
CFR 51.160(e) to demonstrate that regulation of the equipment exempted 
under Rule 200, Section 305 is not needed for the MCAQD's federal NSR 
program to meet requirements for attainment and maintenance of the 
NAAQS or review for compliance with the control strategy. See 83 FR 
26912, 26915 (June 11, 2018). Among other things, we also stated that 
such demonstrations must address identification of the types of 
equipment that the MCAQD considers to be ``agricultural equipment used 
in normal farm operations.'' In its December 20, 2019 SIP Submittal, 
the MCAQD responded by explaining that it had revised Rule 200 to 
exempt only ``fugitive emissions from agricultural equipment used in 
normal farm operations'' [emphasis added]. See Rule 200, Section 
305.2.i.
    The submitted revision to the ``agricultural equipment used in 
normal farm operations'' exemption considerably clarifies and narrows 
the scope of the exemption. Although, as the commenter mentions, 
fugitive emissions are not a specific type of activity or equipment, we 
find that the clarification regarding the scope of the exemption in the 
rule revision that was provided by the MCAQD is sufficient to meet the 
requirements of our June 11, 2018 conditional approval action and the 
CAA. As an initial matter, we note that, in addition to the fact that 
the exemption is now limited to fugitive emissions from agricultural 
equipment used in normal farm operations, the explicit language of the 
exemption provision clearly specifies that it does not apply to any 
equipment that would otherwise require a permit under Title V of the 
Act. A title V permit is required for any major source \4\ as defined 
in 40 CFR 70.2.\5\ A stationary source that is required to obtain a 
major NSR (PSD or nonattainment NSR) permit, is also required to obtain 
a title V permit.\6\

[[Page 8421]]

Therefore, no major stationary source qualifies for the MCAQD's 
``fugitive emissions from agricultural equipment used in normal farm 
operations'' exemption (agricultural equipment exemption), regardless 
of whether any of its emissions units emit fugitive emissions. The rule 
is also clear that the exemption does not apply to any equipment 
subject to the New Source Performance Standards (NSPS) under 40 CFR 
part 60, nor to the National Emission Standards for Hazardous Air 
Pollutants (NESHAP) under 40 CFR parts 61 and 63. Again, this is the 
case regardless of whether the emissions are fugitive or non-fugitive. 
For example, diesel-fired engines are commonly used at agricultural 
sources, and are subject to a NSPS and/or NESHAP requirement.\7\ 
Accordingly, such engines do not qualify for the agricultural equipment 
exemption. The EPA also notes that the MCAQD's permit program only 
applies to stationary sources, therefore any mobile equipment, such as 
tractors, are already exempt from permit program requirements. Thus, 
the exemption is limited to fugitive emissions from agricultural 
equipment used in normal farm operations, located at minor stationary 
sources that are not subject to any NSPS or NESHAP. The EPA believes 
this is a sufficiently small universe of sources to satisfy the 
requirements of 40 CFR 51.160(e) and our June 11, 2018 conditional 
approval action.
---------------------------------------------------------------------------

    \4\ ``Stationary source'' means any building, structure, 
facility, or installation which emits or may emit a regulated NSR 
pollutant. See Rule 100, Section 200.123, 40 CFR 51.165(a)(1)(i), 
and 40 CFR 51.166(b)(5).
    \5\ Under 40 CFR 70.2, a major source is a stationary source of 
air pollutants, as defined in section 302 of the Act, that directly 
emits, or has the potential to emit, 100 tpy or more of any air 
pollutant subject to regulation (including any major source of 
fugitive emissions of any such pollutant, as determined by rule by 
the Administrator). It is also defined as a stationary source that 
emits or has the potential to emit, in the aggregate, 10 tpy or more 
of any hazardous air pollutant which has been listed pursuant to 
section 112(b) of the Act, 25 tpy or more of any combination of such 
hazardous air pollutants, or such lesser quantity as the 
Administrator may establish by rule.
    \6\ For nonattainment areas, a major NSR permit is required for 
a stationary source of air pollutants that emits, or has the 
potential to emit, 100 tons per year or more of any regulated NSR 
pollutant, except that lower emissions thresholds apply in areas 
subject to subpart 2, subpart 3, or subpart 4 of part D, title I of 
the CAA (e.g., since Maricopa County is a serious nonattainment area 
for PM10, an emissions threshold of 70 tpy applies). See 
Rule 240, Section 202 and 40 CFR 51.165(a)(1)(iv)(A)(1). For 
attainment or unclassifiable areas, a major NSR permit is required 
for a stationary source of air pollutants, that belongs to one of 
the 28 source categories, and which emits, or has the potential to 
emit, 100 tons per year or more of any regulated NSR pollutant; a 
major NSR permit is also required for a stationary source which 
emits, or has the potential to emit, 250 tons per year or more of a 
regulated NSR pollutant. See Rule 240, Section 203, 40 CFR 
51.166(b)(1)(i)(a)-(b) and 40 CFR 52.21(b)(1)(i)(a)-(b).
    \7\ See the NSPS regulations at 40 CFR part 60, subparts IIII 
and JJJJ, and the NESHAP regulations 40 CFR part 63, subparts ZZZZ.
---------------------------------------------------------------------------

    The EPA also disagrees with the commenter's claim that the revision 
to Section 305.2.i is too vague to be enforceable. Fugitive emissions 
are defined in Rule 100, Section 200.56 as ``[a]ny emission which could 
not reasonably pass through a stack, chimney, vent, or other 
functionally equivalent opening.'' This definition is consistent with 
the EPA's regulatory definition of ``fugitive emissions'' for SIP-
approved PSD and NNSR programs at 40 CFR 51.166(b)(20) and 
51.165(a)(1)(ix), respectively. The MCAQD considers this definition and 
the specific circumstances of the emissions-generating activity when 
implementing various NSR requirements and determining whether emissions 
are fugitive. In this case, the MCAQD can determine if the emissions 
from agricultural equipment are fugitive, and thus qualify for the 
exemption, before they address whether they are used in ``normal farm 
operations.'' Under the federal NSR permitting program, fugitive 
emissions need not be considered when determining permit requirements, 
unless the source is one of the categorical sources identified. See 
Rule 100, Section 200.28; 40 CFR 51.165(a)(1)(iv)(C) and 
51.166(b)(1)(iii). Therefore, we disagree with the commenter that the 
MCAQD's exemption prevents scrutiny of whether potentially exempt 
emissions are, in fact, fugitive emissions. We also note that the 
MCAQD's SIP-approved minor NSR program already exempts fugitive 
emissions from permit requirements for a minor source that doesn't 
belong to one of the categorical sources under Rule 100, Section 
200.28. See 84 FR 13543 (April 5, 2019) and 84 FR 18392 (May 1, 2019).
    In sum, while the revised exemption does not specifically define 
``agricultural equipment used in normal farm operations,'' we have 
determined that the revision clarifies and narrows how the exemption is 
used and addresses the concerns in our conditional approval regarding 
the need for additional clarification regarding this exemption.
    Comment: The commenter stated that the MCAQD still provides no 
basis for determining that fugitive emissions from ``agricultural 
equipment used in normal farm operations'' do not need to be regulated 
as part of the MCAQD's minor NSR program under 40 CFR 51.160(e). The 
commenter stated that although the EPA compared the MCAQD's exemption 
to a similarly worded exemption in the State regulations implemented by 
the ADEQ, the ADEQ's regulation suffers from the same problem. The 
commenter stated that, as with the ADEQ's exemption, the MCAQD's 
exemption violates CAA section 110(l) and Appendix V, sections 2.2(d) 
and 2.2(e).
    Response: The EPA respectfully disagrees with this comment. The 
MCAQD's December 20, 2019 SIP Submittal provides a rationale and basis 
for the exemption of certain agricultural equipment used in normal farm 
operations under 40 CFR 51.160(e). See December 20, 2019 MCAQD 
Submittal at 12-14. This information, in addition to other available 
information, demonstrates that the MCAQD reasonably concluded that the 
exemption of fugitive emissions from agricultural equipment used in 
normal farm operations is inconsequential to attainment and maintenance 
of the NAAQS.\8\
---------------------------------------------------------------------------

    \8\ In reviewing the MCAQD's minor NSR program under 40 CFR 
51.160(e), the EPA considered it appropriate to exclude emissions 
from its NSR program if such emissions would be ``inconsequential to 
attainment or maintenance of the NAAQS.'' See 86 FR 31927, 31936, 
footnote 21 (June 16, 2021). This was the same standard that the EPA 
used in developing the permitting thresholds for its minor NSR 
program for Indian country. See 76 FR 38748, 38758 (July 1, 2011).
---------------------------------------------------------------------------

    As discussed in the EPA's response to the previous comment, the 
exemption in Rule 200, Section 305.2.i for agricultural equipment used 
in normal farm operations only applies to fugitive emissions, is only 
available to minor sources, and is not available for sources subject to 
an NSPS or NESHAP. Additionally, the MCAQD's SIP-approved minor NSR 
program already exempts fugitive emissions from permit requirements for 
a minor source that doesn't belong to one of the categorical sources 
under Rule 100, Section 200.28. See 84 FR 13543 (April 5, 2019) and 84 
FR 18392 (May 1, 2019).
    Thus, there is sufficient evidence that the exemption for fugitive 
emissions from agricultural equipment used in normal farm operations is 
available only to a very narrow group of minor sources. Such emissions 
are already exempt from regulation under NSR, or they come from 
stationary equipment such as boilers or engines, which are subject to 
the NSPS and thus do not qualify for the exemption in Rule 200, Section 
305. We therefore find the MCAQD's exemption for fugitive emissions 
from agricultural equipment used in normal farm operations to be 
reasonable under 40 CFR 51.160(e).
    The commenters also indicate that the EPA's approval of the MCAQD's 
2019 NSR Submittal conflicts with the requirement in CAA section 110(l) 
that the EPA ``shall not approve a revision of a plan if the revision 
would interfere with any applicable requirement concerning attainment 
and reasonable further progress . . . or any other applicable 
requirement of this chapter.'' For the reasons stated in this document 
and in our proposal, we continue to find that this action strengthens 
the overall SIP and does not relax or otherwise interfere with any SIP 
requirements related to attaining the NAAQS in Maricopa County, 
Arizona.
    The commenters make the related argument that the MCAQD's SIP 
revision does not satisfy section 2.2(d) of Appendix V to 40 CFR part 
51.\9\ As

[[Page 8422]]

described above, the MCAQD's 2019 NSR Submittal contains sufficient 
information to support our conclusion that the MCAQD's NSR program 
meets the requirements of the CAA and its implementing regulations and 
will not interfere with attainment or maintenance of the NAAQS.
---------------------------------------------------------------------------

    \9\ The commenters reference the portion of section 2.2(d) that 
requires SIP submittals to demonstrate ``that the national ambient 
air quality standards, prevention of significant deterioration 
increments, reasonable further progress demonstration, and 
visibility, as applicable, are protected if the plan is approved and 
implemented.'' See 40 CFR part 51, Appendix V, section 2.2(d).
---------------------------------------------------------------------------

    Lastly, in response to the commenter's argument that the MCAQD 
should have included a modeling demonstration to meet the requirements 
of section 2.2(e) of Appendix V to 40 CFR part 51, the commenters have 
not accurately characterized these requirements. We do not interpret 
section 2.2(e) of Appendix V to require that every SIP submittal 
contain a modeling demonstration, as implied by the commenters. 
Instead, when a modeling demonstration is necessary and is therefore 
included in a submittal to support the SIP revision, then the submittal 
must also contain the underlying modeling information outlined in 
section 2.2(e). We find that section 2.2(e) of Appendix V is not 
applicable to the MCAQD's NSR Submittal because modeling was not used 
to support this SIP revision nor was a modeling demonstration required 
in this instance.
    For the reasons discussed above, we find that the MCAQD reasonably 
concluded that the exemption of ``fugitive emissions from agricultural 
equipment used in normal farm operations'' from its minor NSR program 
will not interfere with attainment or maintenance of the NAAQS, 
consistent with 40 CFR 51.160(e). Because the exemption will not 
interfere with attainment or maintenance of the NAAQS, or interfere 
with the overall control strategy, it is consistent with CAA section 
110(l) and section 2.2(d) of Appendix V to 40 CFR part 51.
    Comment: The commenter stated that, while fugitive dust emissions 
from farm operations are primarily addressed through Arizona's Ag BMP 
general permit program, experience with the Ag BMP program in both 
Maricopa County and Pinal County has demonstrated that it is inadequate 
to ensure compliance with the PM10 NAAQS. The commenter 
further stated that both the MCAQD and ADEQ PM10 
nonattainment areas continue to violate the NAAQS decades after the Ag 
BMP program was adopted and agricultural emissions are a key 
contributor. The commenter also noted that the EPA proposed a limited 
approval and limited disapproval of Arizona's Ag BMP statute and 
regulations for Arizona on February 26, 2021. The commenter indicated 
that in light of these concerns, the EPA must disapprove the MCAQD's 
exemption for ``agricultural equipment used in normal farm 
operations.''
    Response: The EPA respectfully disagrees that it must disapprove 
the MCAQD's exemption for ``agricultural equipment used in normal farm 
operations'' based on the commenter's concerns about Arizona's Ag BMP 
program. As discussed in detail in our responses above, we find that 
the MCAQD's exemption from NSR review of a narrow subset of minor 
agricultural sources with fugitive emissions through its exemption for 
``fugitive emissions from agricultural equipment used in normal farm 
operations'' is reasonable. The EPA is not evaluating, updating, or 
relying on the existing EPA-approved Ag BMP program rules in the 
Arizona SIP as part of this rulemaking.\10\ We understand that the ADEQ 
submitted revisions to the Arizona SIP to update the Ag BMP rules; 
however, those revisions are not part of our NSR rulemaking action.
---------------------------------------------------------------------------

    \10\ Further, to the extent the commenter has raised concerns 
about the regulation of air pollution sources located in Pinal 
County, the commenter has not explained how those concerns are 
relevant to this rulemaking action, which pertains specifically to 
the MCAQD's NSR program, which applies only in Maricopa County.
---------------------------------------------------------------------------

B. Public Hearing Requirements for Minor NSR Requirements in Rule 241

    Comment: The commenter stated that the MCAQD revised Rule 241, 
Section 310 by deleting public hearing requirements and stated that the 
revised provision provides that the public notice requirements in Rules 
210 and/or 220 shall be required if the emissions of any one pollutant 
is equal to or greater than the public notice thresholds as defined in 
Rule 100. The commenter further noted that the EPA stated that the same 
or similar language that was deleted from Rule 241, Section 310 was 
contained in portions of Rules 210 and 220, and that therefore the 
change was consistent with the requirements of 40 CFR 51.161(a), and 
the EPA's regulations at 40 CFR 51.160-164. The commenter then states 
that Rule 210, Sections 408.4.g and 408.5, and Rule 220, Sections 407.5 
and 407.7 contain more than just public notice requirements, but also 
contain requirements to accept public comments and hold a hearing upon 
request. The commenter concluded by asserting that Rule 241, Section 
310 should be amended to clarify that it incorporates all of the public 
participation requirements in Rules 210 and 220.
    Response: The EPA respectfully disagrees with the commenter that 
Rule 241, Section 310 should be amended to make the suggested 
clarification. Rule 241, Section 310 states that ``Public notice 
requirements pursuant to Rules 210 and or 220 of these rules shall be 
required for a permit or permit revision if . . .'' emissions are equal 
to or greater than the public notice thresholds in Rule 100. The public 
notice requirements contained in Rules 210 and 220 are found in 
Sections 408 and 407, respectively, which are titled ``PUBLIC 
PARTICIPATION.'' Critically, the public hearing requirements of those 
rules contain public notice requirements, such as the requirement to 
publish a notice at least two times in a newspaper of general 
circulation to ensure adequate notice to the affected public. The 
requirement to accept public comments is also linked to the requirement 
to provide public notice in both rules, such as the requirement to 
allow at least 30 days for public comment following public notice of 
the comment period. While we agree that it would be clearer if Rule 
241, Section 310 stated that the ``public participation'' rather than 
the ``public notice'' requirements of Rules 210 and/or 220 must be met, 
we believe it is sufficiently clear that all of the public 
participation requirements in Rule 210, Section 408 and Rule 220, 
Section 407 are applicable if emissions are equal to or greater than 
the public notice thresholds in Rule 100. Therefore, we continue to 
find that the revisions to Rule 241, Section 310 are acceptable and 
consistent with the requirements of the Act and its implementing 
regulations.

C. Public Notification Requirements for General Permits in Rule 230

    The commenter also provided comments regarding our proposed 
approval of Rule 230 into the MCAQD portion of the Arizona SIP. The EPA 
is deferring final action on Rule 230 at this time. Therefore, the EPA 
is not addressing these comments as part of this final action.

III. Additional Developments After Notice of Proposed Rulemaking

    On January 29, 2021, the U.S. Court of Appeals for the District of 
Columbia Circuit issued its opinion in Sierra Club v. EPA (Case No. 15-
1465), granting in part and denying in part petitions for review of 
four provisions of the 2015 and 2018 ozone NAAQS implementation rules. 
Among other things, the court vacated the provisions

[[Page 8423]]

of the rule allowing interprecursor trading of ozone precursors (See 
2018 Implementation Rule, 83 FR 62998, 63016-63021). The court's 
judgment became final and effective on March 23, 2021, when the court 
issued its mandate. In response to this, on June 10, 2021, the ADEQ 
withdrew the provisions in Rule 240, Section 304.4.e.(1) for 
interpollutant offsetting from the NNSR requirements of the rule. The 
EPA finds this withdrawal acceptable, given the court's vacatur of 
these provisions in the EPA's regulations. Accordingly, this provision 
will not be included in the version of Rule 240 incorporated into the 
Maricopa County portion of the Arizona SIP.
    We note that the EPA recently adopted a rule known as the NSR Error 
Corrections Rule, effective August 18, 2021, which corrected minor, 
inadvertent, and non-substantive errors in 40 CFR parts 51 and 52, 
which govern NSR permitting programs, and updated the regulatory text 
to reflect statutory changes and certain court decisions vacating 
elements of the regulatory text, but did not change the requirements 
within these programs. See 86 FR 37918 (July 19, 2021). States have 
discretion as to when to make the changes indicated in this rulemaking 
and may choose to combine them with other SIP submittals. See 86 FR 
37918, 37923-37924. Accordingly, this recent rulemaking does not affect 
our final action.

IV. EPA Action

    No comments were submitted that change our assessment that the 
MCAQD's Rules 100, 200, 210, 220, 240, and 241 satisfy the applicable 
CAA requirements, nor were any comments submitted that change our 
assessment that certain MCAQD rules should be removed from the Arizona 
SIP. As discussed above, we are deferring action on Rule 230 at this 
time. Therefore, as authorized under CAA sections 110(k)(3) and 301(a), 
and for the reasons set forth in our February 23, 2021 proposed rule, 
we are finalizing full approval of submitted Rules 100, 200, 210, 220, 
240 (except Section 304.4.e.(1)), and 241, in the MCAQD portion of the 
Arizona SIP. We are also removing from the MCAQD portion of the Arizona 
SIP the rules identified in Table 2.
    This action incorporates Rules 100, 200, 210, 220, 240 (except 
Section 304.4.e.(1)), and 241 into the federally enforceable SIP 
through revisions to 40 CFR 52.120 (Identification of plan). We are 
amending 40 CFR 52.119(b) (Identification of plan--conditional 
approvals) to remove the conditional approval of Rules 100 and 200 
since the MCAQD's December 20, 2019 Submittal addressed the 
deficiencies identified by the EPA, and we are now fully approving 
Rules 100 and 200. We are amending the PSD FIP requirements in 40 CFR 
52.144 (Significant deterioration of air quality) since we are 
approving the PSD program provisions in Rule 240 into the MCAQD portion 
of the Arizona SIP. We are also amending the visibility FIP in 40 CFR 
52.145(b) (Visibility protection) since we have determined that the 
MCAQD's NNSR and PSD programs comply with the visibility requirements 
in 40 CFR 51.307.

V. 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 MCAQD 
rules described in Table 1 of this preamble, with the exception of Rule 
230. The EPA has made, and will continue to make, these materials 
available through https://www.regulations.gov and in hard copy at the 
EPA Region IX office (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 the EPA 
for inclusion in the Arizona SIP, have been incorporated by reference 
by the EPA into that plan, are federally enforceable under sections 110 
and 113 of the CAA as of the effective date of the final rulemaking of 
the EPA's approval, and will be incorporated by reference in the next 
update to the SIP compilation.\11\
---------------------------------------------------------------------------

    \11\ 62 FR 27968 (May 22, 1997).
---------------------------------------------------------------------------

    Also in this document, as described in the amendments to 40 CFR 
part 52 set forth below, the EPA is removing provisions from the EPA-
approved rules for the ADEQ portion of the Arizona SIP, which is 
incorporated by reference in accordance with the requirements of 1 CFR 
part 51.

VI. 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 applicable 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:
     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.);
     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 Clean Air Act; and
     Does not provide the 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 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).
    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

[[Page 8424]]

submit a report containing this action 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 Clean Air Act, petitions for 
judicial review of this action must be filed in the United States Court 
of Appeals for the appropriate circuit by [Insert date 60 days after 
date of publication in the Federal Register]. 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 CAA section 307(b)(2).
