Approval and Promulgation of Implementation Plans; Oklahoma; 
State Implementation Plan Revisions for Interstate Transport of 
Pollution, Prevention of Significant Deterioration, Nonattainment New 
Source Review, Source Registration and Emissions Reporting and Rules of 
Practice and Procedure

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing to approve part of a State Implementation 
Plan (SIP) revision submitted by the State of Oklahoma for the purpose 
of addressing the ``good neighbor'' provisions of Clean

[[Page 56924]]

Air Act (the Act or CAA) section 110(a)(2)(D)(i) for the 1997 8-hour 
ozone National Ambient Air Quality Standards (NAAQS or standards) and 
the 1997 fine particulate matter (PM<INF>2.5</INF>) NAAQS. This SIP 
revision satisfies a portion of the State's obligation to submit a SIP 
revision that demonstrates that adequate provisions are in place to 
prohibit air emissions from adversely affecting another State's air 
quality through interstate transport. In this action, EPA is proposing 
to approve the Oklahoma Interstate Transport SIP provisions that 
address the requirement of section 110(a)(2)(D)(i)(II) that emissions 
from sources in Oklahoma do not interfere with measures required in the 
SIP of any other State under part C of the CAA to prevent ``significant 
deterioration of air quality.'' EPA is also proposing to approve 
portions of the revision to the Oklahoma SIP submitted on February 14, 
2002, which relate to Prevention of Significant Deterioration (PSD) and 
Nonattainment New Source Review (NNSR) for major sources, source 
registration and emissions reporting and other rules of practice and 
procedure (except for revisions relating to minor sources). Finally, 
for purposes of the 1997 8-hour ozone NAAQS, EPA also is proposing to 
approve the portions of the SIP revision submitted on June 24, 2010 to 
include nitrogen oxides (NO<INF>X</INF>) as an ozone precursor in 
Oklahoma's PSD SIP. This action is being taken under section 110 and 
parts C and D of the Act.

I. What action is EPA proposing to take?

A. Oklahoma Demonstration of Adequate Provisions Prohibiting Emissions 
That Interfere With Prevention of Significant Deterioration Measures in 
Other States

    We are proposing to approve a submission from the State of Oklahoma 
demonstrating that the State has adequately addressed one of the 
required elements of the CAA section 110(a)(2)(D)(i), the element that 
requires that the State Implementation Plan prohibit air pollutant 
emissions from sources within a State from interfering

[[Page 56925]]

with measures required to prevent significant deterioration of air 
quality in any other State. We are proposing to determine that 
emissions from sources in Oklahoma do not interfere with measures to 
prevent significant deterioration of air quality in any other State for 
the 1997 8-hour ozone NAAQS or of the 1997 PM<INF>2.5</INF> NAAQS (CAA 
section 110(a)(2)(D)(i)(II)). In this action, we are not addressing the 
elements of section 110(a)(2)(D)(i) for the 1997 8-hour ozone and 
PM<INF>2.5</INF> NAAQS, that pertain to prohibiting air pollutant 
emissions from within Oklahoma from: (1) Significantly contributing to 
nonattainment in any other State, (2) interfering with maintenance of 
the relevant NAAQS in any other State and (3) interfering with measures 
required to protect visibility in any other State. These will be 
addressed in future rulemakings.\1\
---------------------------------------------------------------------------

    \1\ In a separate action we have proposed to limit the 
interstate transport of NO<INF>X</INF> emissions from Oklahoma that 
affect the ability of downwind States to attain and maintain 
compliance with the 1997 ozone NAAQS pursuant to CAA 
110(a)(2)(D)(i)(I) (75 FR 45210, August 2, 2010).
---------------------------------------------------------------------------

    In conjunction with our proposed finding that emissions from 
sources in Oklahoma are not interfering with any other State's PSD 
program, we are proposing to approve: (1) The portion of the SIP 
revision submitted by the State on February 14, 2002 related to PSD for 
major stationary sources and major modifications; and (2) the portion 
of the SIP revision submitted June 24, 2010 addressing NO<INF>X</INF> 
as an ozone precursor for PSD. We are proposing to approve these 
portions of the two SIP revision submittals as revisions to the 
Oklahoma PSD SIP.
    EPA proposes to approve the foregoing revisions relevant to section 
110(a)(2)(D)(i) pursuant to section 110 and part C of the Act.

B. Oklahoma SIP Revisions Submitted on February 14, 2002 and June 24, 
2010

1. February 14, 2002 Submittal
    In addition to proposing to approve the portion of the SIP revision 
submitted on February 14, 2002 that relates to PSD as a revision to the 
Oklahoma PSD SIP, we also are proposing to approve the portions that 
relate to: (1) NNSR permitting requirements for major stationary 
sources and major modifications as a revision to the Oklahoma NNSR SIP; 
(2) source registration and emissions reporting as part of the Oklahoma 
Major NSR SIP and (3) other rules of practice and procedure as part of 
the Oklahoma Major NSR SIP. We are proposing to approve (2) and (3) as 
meeting the PSD and NNSR SIP requirements. We are not acting upon the 
SIP revision submittal for Minor NSR SIP purposes, only for Major NSR 
SIP purposes. We will take separate action later in the Federal 
Register on the submittal with regard to the Minor NSR SIP 
requirements.
    The submitted revision affects Title 252 of the Oklahoma 
Administrative Code (OAC 252), the official compilation of agency rules 
and executive orders for the State of Oklahoma. The majority of the 
revisions are administrative in nature, stemming from the State's 
initiative to repeal or otherwise modify redundant or incorrect 
language within the OAC. The variety of revisions includes recodified 
portions of the Oklahoma SIP, deletions of duplicative and outdated 
rules, and edits that simplify text and correct errors.
    The revisions submitted in 2002 proposed for approval are discussed 
in more detail in the Technical Support Document (TSD) found in the 
electronic docket for this action. The electronic docket can be found 
at the Web site http://www.regulations.gov (docket number EPA-R06-OAR-
2007-0314).
2. June 24, 2010 Submittal
    In addition, we are proposing to approve only the portion of the 
SIP revision submitted by Oklahoma on June 24, 2010 to regulate 
NO<INF>X</INF> emissions as a precursor to ozone in its PSD program for 
major sources. We are only acting on the June 24, 2010 submittal as it 
relates to NO<INF>X</INF> as an ozone precursor. We will take separate 
action on the remainder of the June 24, 2010 submittal in a future 
Federal Register notice.

II. What is a SIP?

    Section 110(a) of the Clean Air Act (CAA) requires each State to 
develop a plan that provides for the implementation, maintenance, and 
enforcement of the national ambient air quality standards (NAAQS). EPA 
establishes NAAQS under section 109 of the CAA. Currently, the NAAQS 
address six criteria pollutants: Carbon monoxide, nitrogen dioxide, 
ozone, lead, particulate matter, and sulfur dioxide.
    The plan developed by a State is referred to as the State 
implementation plan (SIP).
    The content of the SIP is specified in section 110 of the CAA, 
other provisions of the CAA, and applicable regulations. SIPs can be 
extensive, containing State regulations or other enforceable measures 
and various types of supporting information, such as emissions 
inventories, monitoring networks, and modeling demonstrations.
    A primary purpose of the SIP is to provide the air pollution 
regulations, control strategies, and other means or techniques 
developed by the State to ensure that the ambient air within that State 
meets the NAAQS. However, another important aspect of the SIP is to 
ensure that emissions from within the State do not have certain 
prohibited impacts upon the ambient air in other States through 
interstate transport of pollutants. This SIP requirement is specified 
in section 110(a)(2)(D) of the CAA. Pursuant to that provision, each 
State's SIP must contain provisions adequate to prevent, among other 
things, emissions that interfere with measures required to be included 
in the SIP of any other State to prevent significant deterioration of 
air quality in any other State.
    States are required to update or revise SIPs under certain 
circumstances. One such circumstance is EPA's promulgation of a new or 
revised NAAQS. Each State must submit these revisions to EPA for 
approval and incorporation into the Federally-enforceable SIP.

III. What is the background for this proposed action?

    On July 18, 1997, EPA promulgated new NAAQS for 8-hour ozone and 
for fine particulate matter (PM<INF>2.5</INF>). This action is being 
taken in response to the promulgation of the 1997 8-hour ozone NAAQS 
and 1997 PM<INF>2.5</INF> NAAQS. This action does not address the 
requirements for the 2006 PM<INF>2.5</INF> NAAQS or the 2008 8-hour 
ozone NAAQS; those standards will be addressed in later actions.
    Section 110(a)(1) of the CAA requires States to submit SIPs to 
address a new or revised NAAQS within 3 years after promulgation of 
such standards, or within such shorter period as EPA may prescribe. 
Section 110(a)(2) lists the elements that such new SIPs must address, 
as applicable, including section 110(a)(2)(D)(i), which pertains to 
interstate transport of certain emissions. On August 15, 2006, EPA 
issued its ``Guidance for State Implementation Plan (SIP) Submission to 
Meet Current Outstanding Obligations Under Section 110(a)(2)(D)(i) for 
the 8-Hour Ozone and PM<INF>2.5</INF> National Ambient Air Quality 
Standards'' (2006 Guidance). EPA developed the 2006 Guidance to make 
recommendations to States for making submissions to meet the 
requirements of section 110(a)(2)(D)(i) for the 1997 8-hour ozone 
standards and the 1997 PM<INF>2.5</INF> standards.

[[Page 56926]]

    As identified in the 2006 Guidance, the ``good neighbor'' 
provisions in section 110(a)(2)(D)(i) require each State to submit a 
SIP that prohibits emissions that adversely affect another State in the 
ways contemplated in the statute. Section 110(a)(2)(D)(i) contains four 
distinct requirements related to the impacts of interstate transport. 
The SIP must prevent sources in the State from emitting pollutants in 
amounts which will: (1) Contribute significantly to nonattainment of 
the NAAQS in other States; (2) interfere with maintenance of the NAAQS 
in other States; (3) interfere with provisions to prevent significant 
deterioration of air quality in other States; or (4) interfere with 
efforts to protect visibility in other States.
    On May 1, 2007, we received a SIP revision from the State of 
Oklahoma intended to address the requirements of section 
110(a)(2)(D)(i) for both the 1997 8-hour ozone standards and 1997 
PM<INF>2.5</INF> standards. In this rulemaking we are addressing only 
the requirement that pertains to preventing sources in Oklahoma from 
emitting pollutants that will interfere with measures required to 
prevent significant deterioration of air quality in other States. In 
its submission, the State of Oklahoma stated that its New Source Review 
program for major sources satisfies this requirement. With this 
submission, the State would meet the requirement as contemplated in the 
2006 Guidance for SIP submissions to meet the third element of CAA 
110(a)(2)(D)(i).
    On February 14, 2002 and June 24, 2010, the State of Oklahoma also 
submitted revisions to its SIP regulations to EPA. The 2002 revisions 
require certain stationary sources of air pollution to report annual 
emissions (an emissions inventory) to the State by March 1 of each 
year, with the provision for an extension of up to 60 days. The 
revisions also incorporate requirements of the Oklahoma Uniform 
Environmental Permitting Act (UEPA), which requires that the Oklahoma 
Department of Environmental Quality fit licenses, permits, 
certificates, approvals and registrations into a category, or Tier, 
established under the uniform environmental permitting rules. The UEPA 
was created to streamline the permitting process and is located in 
Oklahoma Statute Title 27A Environment and Natural Resources, Chapter 2 
Oklahoma Environmental Quality Code, Sections 1 through 12. We 
previously approved portions of the February 14, 2002 submittal, (73 FR 
79400, December 29, 2008), but did not act on other portions.
    The June 24, 2010 submittal included revisions to the Oklahoma PSD 
regulations necessary to address NO<INF>X</INF> as a precursor for the 
1997 8-hour ozone NAAQS (PSD Requirements for Attainment Areas, OAC 
252:100-8). These revisions are discussed below. The June 24, 2010 
submittal also included revisions to Subchapter 8 in OAC 252:100 
(Permits for Part 70 Sources), which are severable from the 
NO<INF>X</INF> requirements addressed in this proposed action. As we 
are still reviewing the approvability of these other revisions, we are 
not proposing to take action on them in this proposed rulemaking. We 
intend to act on these other revisions in a future rulemaking.

IV. What is EPA's evaluation of the State's submissions?

A. Interference With PSD Measures in Other States

    The third element of section 110(a)(2)(D)(i) requires a SIP to 
contain adequate provisions prohibiting emissions that interfere with 
any other State's required measures to prevent significant 
deterioration of its air quality. EPA's 2006 Guidance made 
recommendations for SIP submissions to meet this requirement with 
respect to both the 1997 8-hour ozone NAAQS and the 1997 
PM<INF>2.5</INF> NAAQS.
    EPA believes that Oklahoma's submission is consistent with the 2006 
Guidance, when considered in conjunction with other PSD program 
revisions that EPA is proposing to approve in this action. The State's 
submittal states that Oklahoma's New Source Review (NSR) program for 
major sources prohibits any source or other type of emission activity 
within the State from emitting any air pollutant in amounts which will 
interfere with measures required to be included in the applicable 
implementation plan of any other State to prevent significant 
deterioration of air quality. Oklahoma's regulations for its PSD 
program were approved by EPA and made part of the SIP on August 25, 
1983 (48 FR 38636).\2\ Oklahoma's requirement to demonstrate that an 
emissions increase would not interfere with another State's PSD 
measures (OAC 252:100-8-35(a)(1)) was previously approved by EPA as 
Section 1.4.4(f) of Oklahoma Regulation 1.4 (see the table at 40 CFR 
52.1920(c)). Oklahoma submitted OAC 252:100-35 as a SIP revision on 
February 14, 2002. The revision recodified the regulation. The 2002 
submittal is further discussed below and in the TSD for this action. 
Oklahoma submitted further revisions to its PSD program regulations on 
June 24, 2010 as discussed below.
---------------------------------------------------------------------------

    \2\ The New Source Review regulations in the Oklahoma SIP are 
found in: (1) OAC 252:100-8, Part 7, (PSD Requirements for 
Attainment Areas) and (2) OAC 252:100-8, Part 9, (Major Sources 
Affecting Nonattainment Areas). There are currently no nonattainment 
areas in Oklahoma.
---------------------------------------------------------------------------

    Consistent with EPA's November 29, 2005, Phase 2 rule for the 1997 
8-hour ozone NAAQS (70 FR 71612), the State submitted a SIP revision on 
June 24, 2010, to modify its PSD program to address NO<INF>X</INF> as 
an ozone precursor (OAC 252:100-8). These revisions are further 
discussed below. EPA believes that the PSD revision for the 1997 8-hour 
ozone NAAQS that makes NO<INF>X</INF> an ozone precursor for PSD 
purposes, taken together with the PSD SIP, the proposed revisions to 
the PSD SIP and the interstate transport SIP, satisfies the 
requirements of the third element of section 110(a)(2)(D)(i) for the 
1997 8-hour ozone NAAQS, i.e., there will be no interference with any 
other State's required PSD measures because the Oklahoma SIP as 
proposed for approval meets current CAA requirements.
    For the PM<INF>2.5</INF> NAAQS, Oklahoma stated in its section 
110(a)(2)(D)(i) submission that its NSR program includes an interim PSD 
permitting program for PM<INF>2.5</INF>. On July 29, 2010 the Oklahoma 
Department of Environmental Quality sent a letter to EPA and stated 
that they would implement the PM<INF>2.5</INF> NAAQS consistent with 
Federal case law, and EPA Administrator petition decisions. ODEQ 
further stated that: (1) They will not proceed on the general 
presumption that PM<INF>10</INF> is always a reasonable surrogate for 
PM<INF>2.5</INF>, (2) for any permit application in which the applicant 
is seeking to rely on the Surrogate Policy, they will include in the 
permit record an adequate rationale or demonstration to support the use 
of PM<INF>10</INF> as a surrogate based on the facts and circumstances 
of the specific permit, (3) the permit record will include an 
explanation of how the impacts from the proposed source construction/
modification on the PM<INF>2.5</INF> levels were determined, and (4) 
they will be mindful of the limits provided in the policy itself, such 
as the need to identify the technical difficulties that justify the 
application of the policy in each specific case. The ODEQ letter is 
included in the electronic docket for this action. With these 
clarifications, EPA believes that Oklahoma's approach to 
PM<INF>2.5</INF> permitting is appropriate.
    On the basis of the analysis presented above EPA is proposing to 
determine that the Oklahoma SIP as revised with respect to PSD program 
requirements, satisfactorily addresses the requirement of CAA section 
110(a)(2)(D)(i)(II) that emissions from Oklahoma sources do not 
interfere with PSD measures in

[[Page 56927]]

other any other State for the 1997 8-hour ozone NAAQS and 1997 
PM<INF>2.5</INF> NAAQS.

B. Oklahoma SIP Revisions Submitted on February 14, 2002

    As discussed above, the SIP revision submitted by Oklahoma on 
February 14, 2002 includes revisions that are administrative in nature 
and incorporate requirements of the Oklahoma Uniform Environmental 
Permitting Act.
    Portions of the February 14, 2002, submittal already have been 
approved by EPA on December 29, 2008 (73 FR 79400). In that action, we 
identified the portions of the submittal for which we took no action: 
Chapter 4 (Rules of Practice and Procedure): Subchapters 1 (General 
Procedures), Subchapter 7 (Environmental Permit Process), and Appendix 
C (Permitting Process Summary); Chapter 100 (Air Pollution Control): 
Subchapter 5 (Registration, Emission Inventory and Annual Operating 
Fees), Subchapter 7 (Permits for Minor Sources), Subchapter 8 (Permits 
for Part 70 Sources), and Subchapter 9 (Excess Emissions Reporting 
Requirements). We noted we would take action on these sections in 
separate rulemakings. On July 16, 2010 the State submitted a letter to 
EPA withdrawing their 2002 submittal for Subchapter 9 (Excess Emissions 
Reporting Requirements).
    We are proposing to approve the provisions of this 2002 SIP 
revision submittal as part of the Oklahoma major NSR SIP. We have 
reviewed the revisions being proposed for approval and believe they are 
consistent with the applicable requirements of the CAA for major NSR. 
Our evaluation of these revisions is discussed in more detail in the 
TSD found in the electronic docket for this action. The electronic 
docket can be found at the Web site http://www.regulations.gov (docket 
number EPA-R06-OAR-2007-0314).
    The revisions also require certain stationary sources of air 
pollution to report annual emissions (an emissions inventory) to the 
State by March 1 of each year, with the provision for an extension of 
up to 60 days (OAC 252:100-5-2.1). The revisions requiring reporting of 
emissions from stationary sources is consistent with our Air Emissions 
Reporting Requirements (40 CFR 51, Subpart A), which calls for States 
to report emissions from stationary sources.
    The provisions submitted by the State that we are proposing to 
approve as part of the Oklahoma Major NSR SIP are the following:
    <bullet> Chapter 4 (Rules of Practice and Procedure): Subchapter 1 
(General Provisions).
    <bullet> Chapter 4, Subchapter 7 (Environmental Permit Process), 
Part 1 (The Process) and Part 3 (Air Quality Division Tiers and Time 
Lines).
    <bullet> Chapter 4, Appendix C (Permitting Process Summary).
    <bullet> Chapter 100: Subchapter 5 (Registration, Emission 
Inventory and Annual Operating Fees).\3\
---------------------------------------------------------------------------

    \3\ The revisions also require certain stationary sources of air 
pollution to report annual emissions (an emissions inventory) to the 
State by March 1 of each year, with the provision for an extension 
of up to 60 days (OAC 252:100-5-2.1). The revisions requiring 
reporting of emissions from stationary sources is consistent with 
our Air Emissions Reporting Requirements (40 CFR 51, Subpart A), 
which calls for States to report emissions from stationary sources. 
We are approving this as it applies to major stationary sources and 
major modifications.
---------------------------------------------------------------------------

    <bullet> Chapter 100: Subchapter 8 (Permits for Part 70 Sources), 
Part 1 (General Provisions).
    <bullet> Chapter 100: Subchapter 8, Part 5 (Permits for Part 70 
Sources).
    <bullet> Chapter 100: Subchapter 8, Part 7 (Prevention of 
Significant Deterioration (PSD) Requirements for Attainment Areas).
    <bullet> Chapter 100: Subchapter 8, Part 9 (Major Sources Affecting 
Nonattainment Areas).
    Thus EPA is proposing approval of these provisions as meeting the 
requirements of section 110 and parts C and D of the Act for a major 
NSR SIP.
    At this time we are not taking action on any portion of the 
February 14, 2002 revision that pertains to minor new source review. 
The minor new source review submitted provisions are severable from the 
major NSR requirements and are severable from the transport SIP 
requirements addressed in this action. We intend to act on these 
provisions in a future rulemaking.

C. Oklahoma PSD SIP Revisions Submitted on June 24, 2010

    The Oklahoma Department of Environmental Quality made a SIP 
revision submitted on June 24, 2010 to meet the requirements of the 8-
hour NAAQS by including revisions to regulate NO<INF>X</INF> emissions 
in its PSD permit program as a precursor to ozone. The revisions add:
    <bullet> NO<INF>X</INF> as an ozone precursor in the definition of 
Regulated NSR pollutant (OAC 252:100-8-31),
    <bullet> That a major source that is major for NO<INF>X</INF> shall 
be considered major for ozone in the definition of Major stationary 
source (OAC 252:100-8-31),
    <bullet> A NO<INF>X</INF> emissions rate of 40 tons per year or 
more in the definition of Significant (OAC 252:100-8-31), and
    <bullet> That any net emissions increase of 100 tons per year or 
more of NO<INF>X</INF> subject to PSD would require an ambient impact 
analysis, including the gathering of air quality data (OAC 252:100-8-
33).
    For the 1997 8-hour ozone NAAQS, the revision to the definition of 
Regulated NSR pollutant meets the Federal definition in 40 CFR 
51.166(b)(49) for NO<INF>X</INF> as an ozone precursor. The revision 
that a major source that is major for NO<INF>X</INF> shall be 
considered major for ozone meets the Federal definition in 40 CFR 
51.166(b)(1). The revision to include a NO<INF>X</INF> emissions rate 
of 40 tons per year or more in the definition of ``Significant'' meets 
the Federal requirement for significant emission rate for 
NO<INF>X</INF> emissions in 40 CFR 51.166(b)(23)(i). The revision that 
any net emissions increase of 100 tons per year or more of 
NO<INF>X</INF> subject to PSD would require an ambient impact analysis, 
including the gathering of air quality data meets the Federal 
requirement for ambient air impact analysis for ozone precursors under 
the footnote for 40 CFR 166(i)(5)(i)(e). Thus, EPA is proposing 
approval of these revisions as meeting the requirements of CAA section 
110 and 40 CFR 51.166 for establishing NO<INF>X</INF> emissions as a 
precursor for ozone.

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, EPA's role is to approve State 
choices, provided that they meet the criteria of the Clean Air Act. 
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:
    <bullet> Is not a ``significant regulatory action'' subject to 
review by the Office of Management and Budget under Executive Order 
12866 (58 FR 51735, October 4, 1993);
    <bullet> Does not impose an information collection burden under the 
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
    <bullet> 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.);
    <bullet> 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);

[[Page 56928]]

    <bullet> Does not have Federalism implications as specified in 
Executive Order 13132 (64 FR 43255, August 10, 1999);
    <bullet> Is not an economically significant regulatory action based 
on health or safety risks subject to Executive Order 13045 (62 FR 
19885, April 23, 1997);
    <bullet> Is not a significant regulatory action subject to 
Executive Order 13211 (66 FR 28355, May 22, 2001);
    <bullet> 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
    <bullet> 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, this proposed rule does not have Tribal implications 
as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), 
because the SIP is not approved to apply in Indian country located in 
the State, and EPA notes that it will not impose substantial direct 
costs on Tribal governments or preempt Tribal law.
