SUPPLEMENTARY INFORMATION: I. Background On November 17, 2016, and December 5, 2017, the Environmental Quality Council (EQC) of the Wyoming Department of Environmental Quality conducted public hearings pursuant to 40 CFR 51.102 to consider the adoption of revisions and additions to the Wyoming Air Quality Standards and Regulations. The EQC approved changes were submitted to the EPA for approval into Wyoming’s State Implementation Plan (SIP) on March 27, 2017 (2017 Submittal) and March 28, 2018 (2018 Submittal). The SIP submittals include: (1) Chapter 8 Nonattainment Area Regulations, Section 10, Incorporation by reference (2017 Submittal); (2) Chapter 8, Nonattainment Area Regulations, Section 3, Conformity of general federal actions to state implementation plans (2018 Submittal), and Section 10, Incorporation by reference (2018 Submittal); (3) Chapter 6, Permitting Requirements, Section 4, Prevention of significant deterioration (2017 Submittal); (4) Chapter 6, PO 00000 Frm 00017 Fmt 4702 Sfmt 4702 34811 Permitting Requirements, Section 14, Incorporation by reference (2018 Submittal); (5) Chapter 3, General Emission Standards, Section 3, Emission standards for nitrogen oxides (2017 Submittal); (6) Chapter 3, General Emission Standards, Section 9, Incorporation by reference (2018 Submittal); and (7) Chapter 2, Ambient Standards, Section 6 (2017 Submittal); (8) Chapter 2, Ambient standards for ozone, and Section 12, Incorporation by reference (2018 Submittal). The March 28, 2018 state submittals include requests to update the code of federal regulations (CFR) date of incorporation by reference to reflect the July 1, 2017 CFR, which supersedes the requested changes in the March 27, 2017 state submittals that incorporated by reference the July 1, 2016 CFR (Chapter 8, Nonattainment Area Regulations, Section 10, Incorporation by reference; Chapter 6, Permitting Requirements, Section 14, Incorporation by reference; Chapter 3, General Emission Standards, Section 9, Incorporation by reference; Chapter 2, Ambient standards for ozone, Section 12, Incorporation by reference). II. Analysis of the State’s Submittal The EPA evaluated the proposed amendments to the Wyoming Air Quality Standards and Regulations submitted by the State of Wyoming on March 27, 2017, and March 28, 2018. The EPA notes that the incorporation by reference updates requested by Wyoming in the March 27, 2017 submittal have been superseded by updates requested in their March 28, 2018 submittal and are not analyzed here. The subsequent analysis for each SIP submittal is as follows: (1) The State is requesting that the EPA correct a reference in Chapter 8, Nonattainment Area Regulations, Section 10, Incorporation by reference, to adopt by reference the July 1, 2016 CFR. This request has been superseded by the a more recent submittal which requests updates to Chapter 8, Section 10, described and analyzed in SIP submittal (2), as follows. (2) The State is requesting that the EPA correct a reference in Chapter 8, Nonattainment Area Regulations, Section 3, Conformity of general federal actions to state implementation plans. Specifically, the request includes a minor typographical correction to particulate matter to maintain consistency with federally approved language in 40 CFR 93.158(a)(4); a change from ‘‘PM10’’ to ‘‘PM’’ in the State’s rule Chapter 8, Section 3(h)(i)(D). The EPA finds that this update is necessary and appropriate. This action E:\FR\FM\23JYP1.SGM 23JYP1 amozie on DSK3GDR082PROD with PROPOSALS1 34812 Federal Register / Vol. 83, No. 141 / Monday, July 23, 2018 / Proposed Rules also proposes to update Chapter 8, Nonattainment Area Regulations, Section 10, Incorporation by reference, to adopt by reference the July 1, 2017 CFR. The State previously submitted SIP revisions for Chapter 8, Section 10 (noted earlier in SIP submittal (1)) on March 27, 2017 that allowed adoption by reference of federal regulations as of July 1, 2016, and have since been superseded by the March 28, 2018 submittal. The EPA finds that this update is necessary and appropriate to cite the more recent July 1, 2017 CFR and incorporate by reference. (3) This action proposes to update Chapter 6, Permitting Requirements, Section 4, Prevention of Significant Deterioration, to remove an outdated Federal Register citation under the definition of ‘tpy CO2 equivalent emission (CO2e),’ in the State’s Rule Chapter 6, Section 4(a) and the location for obtaining a copy of the federal regulation. By deleting the reference to the outdated federal regulation (November 29, 2013), the revised State rule includes the language found in 40 CFR 51.166(b)(48)(ii)(a). This provision of the Prevention of Significant Deterioration (PSD) permit rules describes one of the steps to compute the amount of GHGs emitted, and explains that one multiplies the mass amount of emissions (tpy) for each of the six greenhouse gases, by the gas’s associated global warming potential published at Table A–1 to subpart A of part 98 of this chapter—Global Warming Potentials. The State adopted these amendments in December 2017 and therefore adopted the version of Table A–1 to subpart A of part 98 that was in effect at that time. The EPA believes this update is necessary and appropriate to accurately cite the most recent calculation methodology and GHG’s associated global warming potential. (4) As requested in the State’s March 28, 2018 submittal, the EPA is proposing to update Chapter 6, Section 14, Incorporation by reference to adopt by reference the July 1, 2017 CFR. The State previously submitted SIP revisions for Chapter 6, Section 14 on March 27, 2017, that allowed adoption by reference of federal regulations as of July 1, 2016, and have since been superseded by the March 28, 2018 submittal. The EPA finds that the update is necessary and appropriate to cite the more recent July 1, 2017 CFR and incorporate by reference. (5) This action proposes to update Chapter 3, Section 3, Emission standards for nitrogen oxides, which corrects an inconsistency regarding internal combustion engines. The EPA finds that the requirements governing VerDate Sep<11>2014 16:31 Jul 20, 2018 Jkt 244001 fuel burning equipment (including internal combustion engines) are covered in Chapter 1, Section 3 of the SIP; so, the language removed in Chapter 3, Section 3, (a)(viii), is a vestigial exemption for engines with a heat input less than 200 million Btu per hour that no longer applies. Therefore, the EPA finds that the change made to Chapter 3, Section 3, is necessary and appropriately corrects the noted inconsistency regarding internal combustion engines. Finally, the State’s rulemaking action included an update to the website link for contact information for the Cheyenne Office of the Wyoming Division of Air Quality, Chapter 3, Section 9(a) and (b). The EPA finds it is necessary and appropriate to update the website referenced in the SIP to ensure it is accurate. (6) This action proposes to update Chapter 3, General Emission Standards, Section 9, Incorporation by reference, to adopt by reference from the July 1, 2017 CFR. The State previously submitted SIP revisions for Chapter 3, Section 9 on March 27, 2017, that allowed adoption by reference of federal regulations as of July 1, 2016, and have since been superseded by the March 28, 2018 submittal. The EPA finds that the updates proposed to Chapter 3, Section 9, are necessary and appropriate to cite the more recent July 1, 2017 CFR and incorporate by reference. (7) This action proposes to update Chapter 2, Ambient Standards, Section 6, Ambient standards for ozone. The State has revised Section 6 to include the latest (2015) ozone National Ambient Air Quality Standards (NAAQS). The EPA finds that this update is necessary and appropriate to reflect EPA’s 2015 revision to the ozone NAAQS. 40 CFR 50.19. (8) The State previously submitted SIP revisions for Chapter 2, Section 12, Incorporation by reference on March 27, 2017, that allowed adoption by reference of federal regulations as of July 1, 2016. The EPA finds that this update is necessary and appropriate to update the incorporation by reference date to July 1, 2017, as requested in Wyoming’s March 28, 2018 letter. III. The EPA’s Proposed Action In this action, the EPA is proposing to approve the eight SIP submittals to the Wyoming Air Quality Standards and Regulations submitted by the State of Wyoming on March 27, 2017 and March 28, 2018. This action proposes updates to: (1) Chapter 8 Nonattainment Area Regulations, Section 10, Incorporation by reference (2017 Submittal); (2) Chapter 8, Nonattainment Area Regulations, Section 3, Conformity of PO 00000 Frm 00018 Fmt 4702 Sfmt 4702 general federal actions to state implementation plans (2018 Submittal), and Section 10, Incorporation by reference (2018 Submittal); (3) Chapter 6, Permitting Requirements, Section 4, Prevention of significant deterioration, to remove an outdated Federal Register citation under the definition of ‘tpy CO2 equivalent emission (CO2e)’ (2017 Submittal); (4) Chapter 6, Permitting Requirements, Section 14, Incorporation by reference (2018 Submittal); (5) Chapter 3, General Emission Standards, Section 3, Emission standards for nitrogen oxides, which corrects an inconsistency regarding internal combustion engines (2017 Submittal); (6) Chapter 3, General Emission Standards, Section 9, Incorporation by reference (2018 Submittal); (7) Chapter 2, Ambient Standards, Section 6, to include the latest ozone NAAQS (2017 Submittal); and (8) Chapter 2, Ambient standards for ozone, and Section 12, Incorporation by reference (2018 Submittal). 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 amendments described in section III. The EPA has made, and will continue to make, these materials generally available through www.regulations.gov and at the EPA Region 8 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 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); • Is not an Executive Order 13771 (82 FR 9339, February 2, 2017) regulatory action because SIP approvals are exempted under Executive Order 12866; E:\FR\FM\23JYP1.SGM 23JYP1 Federal Register / Vol. 83, No. 141 / Monday, July 23, 2018 / Proposed Rules • 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 proposed 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). amozie on DSK3GDR082PROD with PROPOSALS1 List of Subjects in 40 CFR Part 52 Environmental protection, Air pollution control, Carbon monoxide, Incorporation by reference, Intergovernmental relations, Lead, Nitrogen dioxide, Ozone, Particulate matter, Reporting and recordkeeping requirements.

This SUPPLEMENTARY INFORMATION section is arranged as follows: Table of Contents I. Background II. State Submittal III. EPA Evaluation IV. Proposed Action V. Statutory and Executive Order Reviews I. Background On October 1, 2015, the EPA promulgated a revision to the ozone NAAQS (2015 ozone NAAQS), lowering the level of both the primary and secondary standards to 0.070 parts per million (ppm).1 Section 110(a)(1) of the CAA requires states to submit, within 3 years after promulgation of a new or revised standard, SIPs meeting the applicable elements of section 110(a)(2).2 One of these applicable requirements is found in section 110(a)(2)(D)(i), otherwise known as the good neighbor provision, which generally requires SIPs to contain adequate provisions to prohibit in-state emissions activities from having certain adverse air quality effects on other states due to interstate transport of pollution. There are four prongs within CAA section 110(a)(2)(D)(i): Section 110(a)(2)(D)(i)(I) contains prongs 1 and 2, while section 110(a)(2)(D)(i)(II) includes prongs 3 and 4. This action addresses the first two prongs under section 110(a)(2)(D)(i)(I). Under prongs 1 and 2 of the good neighbor provision, a state’s SIP for a new or revised NAAQS must contain adequate provisions prohibiting any source or other type of emissions activity within the state from emitting air pollutants in amounts that will contribute significantly to nonattainment of the NAAQS in another state (prong 1) or from interfering with maintenance of the NAAQS in another state (prong 2). Under section 110(a)(2)(D)(i)(I) of the CAA, the EPA gives independent significance to evaluating prong 1 and prong 2. We note that the EPA has addressed the interstate transport requirements of CAA section 110(a)(2)(D)(i)(I) with respect to prior ozone NAAQS in several regulatory actions, including the Cross-State Air Pollution Rule (CSAPR), which addressed interstate transport 1 National Ambient Air Quality Standards for Ozone Final Rule, 80 FR 65292 (October 26, 2015). 2 SIP revisions that are intended to meet the requirements of section 110(a)(1) and (2) of the CAA are often referred to as infrastructure SIPs and the elements under 110(a)(2) are referred to as infrastructure requirements.

SUPPLEMENTARY INFORMATION:

I. Background

    On November 17, 2016, and December 5, 2017, the Environmental 
Quality Council (EQC) of the Wyoming Department of Environmental 
Quality conducted public hearings pursuant to 40 CFR 51.102 to consider 
the adoption of revisions and additions to the Wyoming Air Quality 
Standards and Regulations. The EQC approved changes were submitted to 
the EPA for approval into Wyoming's State Implementation Plan (SIP) on 
March 27, 2017 (2017 Submittal) and March 28, 2018 (2018 Submittal). 
The SIP submittals include: (1) Chapter 8 Nonattainment Area 
Regulations, Section 10, Incorporation by reference (2017 Submittal); 
(2) Chapter 8, Nonattainment Area Regulations, Section 3, Conformity of 
general federal actions to state implementation plans (2018 Submittal), 
and Section 10, Incorporation by reference (2018 Submittal); (3) 
Chapter 6, Permitting Requirements, Section 4, Prevention of 
significant deterioration (2017 Submittal); (4) Chapter 6, Permitting 
Requirements, Section 14, Incorporation by reference (2018 Submittal); 
(5) Chapter 3, General Emission Standards, Section 3, Emission 
standards for nitrogen oxides (2017 Submittal); (6) Chapter 3, General 
Emission Standards, Section 9, Incorporation by reference (2018 
Submittal); and (7) Chapter 2, Ambient Standards, Section 6 (2017 
Submittal); (8) Chapter 2, Ambient standards for ozone, and Section 12, 
Incorporation by reference (2018 Submittal).
    The March 28, 2018 state submittals include requests to update the 
code of federal regulations (CFR) date of incorporation by reference to 
reflect the July 1, 2017 CFR, which supersedes the requested changes in 
the March 27, 2017 state submittals that incorporated by reference the 
July 1, 2016 CFR (Chapter 8, Nonattainment Area Regulations, Section 
10, Incorporation by reference; Chapter 6, Permitting Requirements, 
Section 14, Incorporation by reference; Chapter 3, General Emission 
Standards, Section 9, Incorporation by reference; Chapter 2, Ambient 
standards for ozone, Section 12, Incorporation by reference).

II. Analysis of the State's Submittal

    The EPA evaluated the proposed amendments to the Wyoming Air 
Quality Standards and Regulations submitted by the State of Wyoming on 
March 27, 2017, and March 28, 2018. The EPA notes that the 
incorporation by reference updates requested by Wyoming in the March 
27, 2017 submittal have been superseded by updates requested in their 
March 28, 2018 submittal and are not analyzed here. The subsequent 
analysis for each SIP submittal is as follows:
    (1) The State is requesting that the EPA correct a reference in 
Chapter 8, Nonattainment Area Regulations, Section 10, Incorporation by 
reference, to adopt by reference the July 1, 2016 CFR. This request has 
been superseded by the a more recent submittal which requests updates 
to Chapter 8, Section 10, described and analyzed in SIP submittal (2), 
as follows.
    (2) The State is requesting that the EPA correct a reference in 
Chapter 8, Nonattainment Area Regulations, Section 3, Conformity of 
general federal actions to state implementation plans. Specifically, 
the request includes a minor typographical correction to particulate 
matter to maintain consistency with federally approved language in 40 
CFR 93.158(a)(4); a change from ``PM10'' to ``PM'' in the 
State's rule Chapter 8, Section 3(h)(i)(D). The EPA finds that this 
update is necessary and appropriate. This action

[[Page 34812]]

also proposes to update Chapter 8, Nonattainment Area Regulations, 
Section 10, Incorporation by reference, to adopt by reference the July 
1, 2017 CFR. The State previously submitted SIP revisions for Chapter 
8, Section 10 (noted earlier in SIP submittal (1)) on March 27, 2017 
that allowed adoption by reference of federal regulations as of July 1, 
2016, and have since been superseded by the March 28, 2018 submittal. 
The EPA finds that this update is necessary and appropriate to cite the 
more recent July 1, 2017 CFR and incorporate by reference.
    (3) This action proposes to update Chapter 6, Permitting 
Requirements, Section 4, Prevention of Significant Deterioration, to 
remove an outdated Federal Register citation under the definition of 
`tpy CO2 equivalent emission (CO2e),' in the 
State's Rule Chapter 6, Section 4(a) and the location for obtaining a 
copy of the federal regulation. By deleting the reference to the 
outdated federal regulation (November 29, 2013), the revised State rule 
includes the language found in 40 CFR 51.166(b)(48)(ii)(a). This 
provision of the Prevention of Significant Deterioration (PSD) permit 
rules describes one of the steps to compute the amount of GHGs emitted, 
and explains that one multiplies the mass amount of emissions (tpy) for 
each of the six greenhouse gases, by the gas's associated global 
warming potential published at Table A-1 to subpart A of part 98 of 
this chapter--Global Warming Potentials. The State adopted these 
amendments in December 2017 and therefore adopted the version of Table 
A-1 to subpart A of part 98 that was in effect at that time. The EPA 
believes this update is necessary and appropriate to accurately cite 
the most recent calculation methodology and GHG's associated global 
warming potential.
    (4) As requested in the State's March 28, 2018 submittal, the EPA 
is proposing to update Chapter 6, Section 14, Incorporation by 
reference to adopt by reference the July 1, 2017 CFR. The State 
previously submitted SIP revisions for Chapter 6, Section 14 on March 
27, 2017, that allowed adoption by reference of federal regulations as 
of July 1, 2016, and have since been superseded by the March 28, 2018 
submittal. The EPA finds that the update is necessary and appropriate 
to cite the more recent July 1, 2017 CFR and incorporate by reference.
    (5) This action proposes to update Chapter 3, Section 3, Emission 
standards for nitrogen oxides, which corrects an inconsistency 
regarding internal combustion engines. The EPA finds that the 
requirements governing fuel burning equipment (including internal 
combustion engines) are covered in Chapter 1, Section 3 of the SIP; so, 
the language removed in Chapter 3, Section 3, (a)(viii), is a vestigial 
exemption for engines with a heat input less than 200 million Btu per 
hour that no longer applies. Therefore, the EPA finds that the change 
made to Chapter 3, Section 3, is necessary and appropriately corrects 
the noted inconsistency regarding internal combustion engines. Finally, 
the State's rulemaking action included an update to the website link 
for contact information for the Cheyenne Office of the Wyoming Division 
of Air Quality, Chapter 3, Section 9(a) and (b). The EPA finds it is 
necessary and appropriate to update the website referenced in the SIP 
to ensure it is accurate.
    (6) This action proposes to update Chapter 3, General Emission 
Standards, Section 9, Incorporation by reference, to adopt by reference 
from the July 1, 2017 CFR. The State previously submitted SIP revisions 
for Chapter 3, Section 9 on March 27, 2017, that allowed adoption by 
reference of federal regulations as of July 1, 2016, and have since 
been superseded by the March 28, 2018 submittal. The EPA finds that the 
updates proposed to Chapter 3, Section 9, are necessary and appropriate 
to cite the more recent July 1, 2017 CFR and incorporate by reference.
    (7) This action proposes to update Chapter 2, Ambient Standards, 
Section 6, Ambient standards for ozone. The State has revised Section 6 
to include the latest (2015) ozone National Ambient Air Quality 
Standards (NAAQS). The EPA finds that this update is necessary and 
appropriate to reflect EPA's 2015 revision to the ozone NAAQS. 40 CFR 
50.19.
    (8) The State previously submitted SIP revisions for Chapter 2, 
Section 12, Incorporation by reference on March 27, 2017, that allowed 
adoption by reference of federal regulations as of July 1, 2016. The 
EPA finds that this update is necessary and appropriate to update the 
incorporation by reference date to July 1, 2017, as requested in 
Wyoming's March 28, 2018 letter.

III. The EPA's Proposed Action

    In this action, the EPA is proposing to approve the eight SIP 
submittals to the Wyoming Air Quality Standards and Regulations 
submitted by the State of Wyoming on March 27, 2017 and March 28, 2018. 
This action proposes updates to: (1) Chapter 8 Nonattainment Area 
Regulations, Section 10, Incorporation by reference (2017 Submittal); 
(2) Chapter 8, Nonattainment Area Regulations, Section 3, Conformity of 
general federal actions to state implementation plans (2018 Submittal), 
and Section 10, Incorporation by reference (2018 Submittal); (3) 
Chapter 6, Permitting Requirements, Section 4, Prevention of 
significant deterioration, to remove an outdated Federal Register 
citation under the definition of `tpy CO2 equivalent 
emission (CO2e)' (2017 Submittal); (4) Chapter 6, Permitting 
Requirements, Section 14, Incorporation by reference (2018 Submittal); 
(5) Chapter 3, General Emission Standards, Section 3, Emission 
standards for nitrogen oxides, which corrects an inconsistency 
regarding internal combustion engines (2017 Submittal); (6) Chapter 3, 
General Emission Standards, Section 9, Incorporation by reference (2018 
Submittal); (7) Chapter 2, Ambient Standards, Section 6, to include the 
latest ozone NAAQS (2017 Submittal); and (8) Chapter 2, Ambient 
standards for ozone, and Section 12, Incorporation by reference (2018 
Submittal).

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 amendments described in section III. The EPA has made, 
and will continue to make, these materials generally available through 
www.regulations.gov and at the EPA Region 8 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 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);
     Is not an Executive Order 13771 (82 FR 9339, February 2, 
2017) regulatory action because SIP approvals are exempted under 
Executive Order 12866;

[[Page 34813]]

     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 proposed 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).
