[EPA-R06-OAR-2018-0673; FRL-9992-04-Region 6]


Air Plan Approval; Texas; Infrastructure for the 2015 Ozone 
National Ambient Air Quality Standard

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: Pursuant to the Clean Air Act (CAA or the Act), the 
Environmental Protection Agency (EPA) is proposing to approve elements 
of two State Implementation Plan (SIP) submissions from the State of 
Texas for the 2015 Ozone (O3) National Ambient Air Quality 
Standard (NAAQS). These submittals address how the existing SIP 
provides for implementation, maintenance, and enforcement of the 2015 
O3 NAAQS (infrastructure SIP or i-SIP). The i-SIP ensures 
that the Texas SIP is adequate to meet the state's responsibilities 
under the CAA for this NAAQS.

DATES: Written comments must be received on or before May 30, 2019.

ADDRESSES: Submit your comments, identified by Docket No. EPA-R06-OAR-
2018-0673, at https://www.regulations.gov or via email to 
[email protected]. Follow the online instructions for submitting 
comments. Once submitted, comments cannot be edited or removed from

I. Background

    Below is a short discussion of background on the 2015 Ozone NAAQS 
addressed in this action. For more information, please see the 
Technical Support Document (TSD) in the docket for this action.
    EPA has regulated Ozone since 1971, when we published the first 
NAAQS for Photochemical Oxidants (36 FR 8186, April 30, 1971). Most 
recently, following a periodic review of the 2008 NAAQS for 
O3, EPA revised the primary and secondary O3 
NAAQS to 0.070 ppm (82 FR 65291, October 26, 2015).\1\ The primary 
NAAQS is designed to protect human health, and the secondary NAAQS is 
designed to protect the public welfare.\2\
---------------------------------------------------------------------------

    \1\ Additional information on the history of the NAAQS for ozone 
is available at https://www.epa.gov/ozone-pollution/table-historical-ozone-national-ambient-air-quality-standards-naaqs.
    \2\ Information on ozone formation and health effects is 
available at https://www.epa.gov/ozone-pollution.
---------------------------------------------------------------------------

    Each state must submit a SIP within three years after the 
promulgation of a new or revised NAAQS showing how it meets the 
elements of Section 110(a)(2) of the CAA. This section of Act includes 
a list of specific elements necessary for a States air quality program. 
We term this SIP an infrastructure SIP or i-SIP. On September 13, 2013, 
the EPA issued guidance addressing the i-SIP elements for NAAQS.\3\ On 
August 17, 2018, the

[[Page 18187]]

Chairman of the Texas Commission on Environmental Quality (TCEQ) made 
two submissions to address the 2015 NAAQS for O3.\4\ One 
submittal addresses CAA sections 110(a)(2)(A) through (C) and (E) 
through (M), which we refer to as the infrastructure or ``i-SIP'' 
submittal and the other addresses CAA section 110(a)(2)(D), which we 
refer to as the ``Transport'' submittal.

    \3\ ``Guidance on Infrastructure State Implementation Plan (SIP) 
Elements under Clean Air Act sections 110(a)(1) and 110(a)(2),'' 
Memorandum from Stephen D. Page, September 13, 2013.
    \4\ Additional information, including the history of the 
priority pollutants, their levels, forms and determination of 
compliance; EPA approach for reviewing i-SIP submittal and EPA's 
evaluation; the statute and regulatory citations in the Texas SIP 
specific to the review the specific i-SIP applicable CAA and EPA 
regulatory citations, Federal Register citations for the Texas SIP 
approvals; Texas minor New Source Review program and EPA approval 
activities, and Texas' Prevention of Significant Deterioration 
program can be found in the TSD for this action.
---------------------------------------------------------------------------

    We are proposing to approve the August 17, 2018 Texas i-SIP 
submittal for the 2015 ozone NAAQS in its entirety. We are also 
proposing to approve portions of the August 17, 2018 Texas Transport 
submittal for the 2015 ozone NAAQS. A copy of each of these submittals 
is in the docket for this proposed rulemaking.

II. EPA's Evaluation of the Texas 2015 O3 NAAQS i-SIP and 
Transport Submissions

    Below is a summary of our evaluation of the August 17, 2018 Texas 
submittals for each element of 110(a)(2) that we are proposing to 
approve.\5\
---------------------------------------------------------------------------

    \5\ A detailed discussion of our evaluation can be found in the 
TSD for this action.
---------------------------------------------------------------------------

    (A). Emission limits and other control measures: The SIP must 
include enforceable emission limits and other control measures, means 
or techniques, schedules for compliance and other related matters as 
needed to implement, maintain and enforce each of the NAAQS.\6\
---------------------------------------------------------------------------

    \6\ The specific nonattainment area plan requirements of section 
110(a)(2)(I) are subject to the timing requirements of section 172, 
not the timing requirement of section 110(a)(1). Thus, section 
110(a)(2)(A) does not require that states submit regulations or 
emissions limits specifically for attaining the 2015 Ozone NAAQS. 
Those SIP provisions are due as part of each state's attainment 
plan, and will be addressed separately from the requirements of 
section 110(a)(2)(A). In the context of an infrastructure SIP, EPA 
is not evaluating the existing SIP provisions for this purpose. 
Instead, EPA is only evaluating whether the state's SIP has basic 
structural provisions for the implementation of the NAAQS.
---------------------------------------------------------------------------

    The Texas Clean Air Act (TCAA) provides the TCEQ, its Chairman, and 
its Executive Director with broad legal authority. They may adopt 
emission standards and compliance schedules applicable to regulated 
entities; emission standards and limitations and any other measures 
necessary for attainment and maintenance of national standards; and 
enforce applicable laws, regulations, standards and compliance 
schedules, and seek injunctive relief. This authority has been employed 
in the past to adopt and submit multiple revisions to the Texas SIP. 
The federally-approved SIP for Texas is documented at 40 CFR part 
52.2270. TCEQ's air quality rules and standards are codified at Title 
30, part 1 of the Texas Administrative Code (TAC). Numerous parts of 
the regulations codified into 30 TAC necessary for implementing and 
enforcing the NAAQS have been adopted into the SIP.
    (B) Ambient air quality monitoring/data system: The SIP must 
provide for establishment and implementation of ambient air quality 
monitors, collection and analysis of ambient air quality data, and 
providing the data to EPA upon request.
    The TCAA provides the authority allowing the TCEQ to collect air 
monitoring data, quality-assure the results, and report the data. TCEQ 
maintains and operates a monitoring network to measure levels of ozone, 
as well as other pollutants, in accordance with EPA regulations 
specifying siting and monitoring requirements. All monitoring data is 
measured using EPA-approved methods and subject to the EPA quality 
assurance requirements. TCEQ submits all required data to us, following 
the EPA regulations. The Texas statewide monitoring network was 
approved into the SIP on May 31, 1972 (37 FR 10842, 10895), was revised 
on March 7, 1978 (43 FR 9275), and it undergoes annual review by 
EPA.\7\ In addition, TCEQ submits an assessment of its monitoring 
network every five years, as required by EPA rules. The most recent of 
these 5-year monitoring network assessments was submitted by TCEQ and 
approved by us in July of 2015.\8\ The TCEQ website provides the 
monitor locations and posts past and current concentrations of criteria 
pollutants measured by the State's network of monitors.\9\
---------------------------------------------------------------------------

    \7\ A copy of the 2018 Annual Air Monitoring Network Plan and 
our approval letter are included in the docket for this proposed 
rulemaking.
    \8\ A copy of TCEQ's 2015 5-year ambient monitoring network 
assessment and our response letter are included in the docket for 
this proposed rulemaking.
    \9\ See https://www.tceq.texas.gov/agency/air_main.html.
---------------------------------------------------------------------------

    (C) Program for enforcement of control measures: The SIP must 
include the following three elements: (1) A program providing for 
enforcement of the measures in CAA section 110(a)(2)(A); (2) a program 
for the regulation of the modification and construction of stationary 
sources as necessary to protect the applicable NAAQS (i.e., state-wide 
permitting of minor sources); and (3) a permit program to meet the 
major source permitting requirements of the CAA (for areas designated 
as attainment or unclassifiable for the NAAQS in question). Each of 
these elements is described in more detail in the TSD for this action.
    (1) Enforcement of SIP Measures. As noted earlier, the TCAA 
provides authority for the TCEQ, its Chairman, and its Executive 
Director to enforce the requirements of the TCAA, and any regulations, 
permits, or final compliance orders. These statutes also provide the 
TCEQ, its Chairman, and its Executive Director with general enforcement 
powers. Among other things, they can file lawsuits to compel compliance 
with the statutes and regulations; commence civil actions; issue field 
citations; conduct investigations of regulated entities; collect 
criminal and civil penalties; develop and enforce rules and standards 
related to protection of air quality; issue compliance orders; pursue 
criminal prosecutions; investigate, enter into remediation agreements; 
and issue emergency cease and desist orders. The TCAA also provides 
additional enforcement authorities and funding mechanisms.
    (2) Minor New Source Review (NSR). The SIP is required to include 
measures to regulate construction and modification of stationary 
sources to protect the NAAQS. The Texas minor NSR permitting 
requirements are approved as part of the SIP.\10\
---------------------------------------------------------------------------

    \10\ EPA is not proposing to approve or disapprove the existing 
Texas minor NSR program to the extent that it may be inconsistent 
with EPA's regulations governing this program. EPA has maintained 
that the CAA does not require that new infrastructure SIP 
submissions correct any defects in existing EPA-approved provisions 
of minor NSR programs for EPA to approve the infrastructure SIP for 
element C, program for enforcement of control measures (e.g., 76 FR 
41076-41079). The statutory requirements of section 110(a)(2)(C) 
provide for considerable flexibility in designing minor NSR 
programs. See the TSD for more information.
---------------------------------------------------------------------------

    (3) Prevention of Significant Deterioration (PSD) permit program. 
The Texas PSD portion of the SIP covers all NSR regulated pollutants as 
well as the requirements for the 2015 O3 NAAQS and has been 
approved by EPA (79 FR 66626, November 10, 2014).\11\
---------------------------------------------------------------------------

    \11\ We discuss this requirement further in the TSD.
---------------------------------------------------------------------------

    (D) Interstate and international transport: The requirements for 
interstate transport of O3 emissions are that the SIP 
contain adequate provisions prohibiting O3 emission 
transport to other states which will (1) contribute significantly to 
nonattainment of the NAAQS, (2) interfere with maintenance

[[Page 18188]]

of the NAAQS, (3) interfere with measures required to prevent 
significant deterioration or (4) interfere with measures to protect 
visibility (CAA 110(a)(2)(D)(i)). In addition, states must comply with 
requirements to prevent transport of international air pollution (CAA 
section 110(a)(2)(D)(ii)). EPA often refers to these four requirements 
within CAA section 110(a)(2)(D)(i) as prongs or sub-elements. We are 
not evaluating sub-elements 1, 2, and 4 in this rulemaking action, but 
will address them in a separate action. However, we are proposing to 
approve sub-element 3 of CAA section 110(a)(2)(D)(i), pertaining to the 
prevention of significant deterioration in other states for 
O3. Texas has a SIP-approved PSD program that regulates all 
NSR pollutants, including greenhouse gases, and thus, prevents 
significant deterioration in nearby states. See the TSD for more 
detail.
    Section 110(a)(2)(D)(ii) of the CAA requires SIPs to include 
adequate provisions to ensure compliance with sections 115 and 126 of 
the Act, relating to international and interstate pollution abatement. 
Section 115 of the Act addresses endangerment of public health or 
welfare in foreign countries from pollution emitted in the United 
States. There are no final findings by the EPA that Texas air emissions 
affect other countries. Section 126(a) of the Act requires new or 
modified sources to notify neighboring states of potential impacts from 
such sources. The Texas SIP requires that each major proposed new or 
modified source provide such notification.\12\ The State also has no 
pending obligations under CAA section 126. See the TSD for more detail.
---------------------------------------------------------------------------

    \12\ See September 18, 2002 (67 FR 58697).
---------------------------------------------------------------------------

    (E) Adequate authority, resources, implementation, and oversight: 
The SIP must provide for the following: (1) Necessary assurances that 
the state (and other entities within the state responsible for 
implementing the SIP) will have adequate personnel, funding, and 
authority under state or local law to implement the SIP, and that there 
are no legal impediments to such implementation; (2) requirements 
relating to state boards; and (3) necessary assurances that the state 
has responsibility for ensuring adequate implementation of any plan 
provision for which it relies on local governments or other entities to 
carry out that portion of the plan. Both elements (A) and (E) address 
the requirement that there is adequate authority to implement and 
enforce the SIP and that there are no legal impediments.
    The i-SIP submission for the 2015 O3 NAAQS describes the 
SIP regulations governing the various functions of personnel within the 
TCEQ, including the administrative, technical support, planning, 
enforcement, and permitting functions of the program.
    With respect to funding, the TCAA requires TCEQ to establish an 
emissions fee schedule for sources to fund the reasonable costs of 
administering various air pollution control programs and authorizes 
TCEQ to collect additional fees necessary to cover reasonable costs 
associated with processing of air permit applications.
    As required by the CAA, the Texas statutes and the SIP stipulate 
that any board or body, which approves permits or enforcement orders, 
must have a majority of members who represent the public interest and 
do not derive any ``significant portion'' of their income from persons 
subject to permits and enforcement orders or who appear before the 
board on issues related to the CAA or the TCAA. The members of the 
board or body, or the head of an agency with similar powers, are 
required to adequately disclose any potential conflicts of interest.
    With respect to assurances that the State has responsibility to 
implement the SIP adequately when it authorizes local or other agencies 
to carry out portions of the plan, the Texas statutes and the SIP 
designate the TCEQ as the primary air pollution control agency and TCEQ 
maintains authority to ensure implementation of any applicable plan 
portion. More detail is provided in the TSD for this action.
    (F) Stationary source monitoring system: The SIP must provide for 
the establishment of a system to monitor emissions from stationary 
sources and to submit periodic emission reports. It must require the 
installation, maintenance, and replacement of equipment, and the 
implementation of other necessary steps, by owners or operators of 
stationary sources, to monitor emissions from such sources. The SIP 
shall also require periodic reports on the nature and amounts of 
emissions and emissions-related data from such sources, and require 
that the state correlate the source reports with emission limitations 
or standards established under the CAA. These reports must be made 
available for public inspection at reasonable times.
    The TCAA authorizes the TCEQ to require persons engaged in 
operations which result in air pollution to monitor or test emissions 
and to file reports containing information relating to the nature and 
amount of emissions. There also are SIP-approved state regulations 
pertaining to sampling and testing and requirements for reporting of 
emissions inventories. In addition, SIP-approved rules establish 
general requirements for maintaining records and reporting emissions.
    The TCEQ uses this information, in addition to information obtained 
from other sources, to track progress towards maintaining the NAAQS, 
developing control and maintenance strategies, identifying sources and 
general emission levels, and determining compliance with SIP-approved 
regulations and additional EPA requirements. The SIP requires this 
information be made available to the public. Provisions concerning the 
handling of confidential data and proprietary business information are 
included in the SIP-approved regulations. These rules specifically 
exclude from confidential treatment any records concerning the nature 
and amount of emissions reported by sources. More detail and links to 
Texas emissions data are provided in the TSD for this action.
    (G) Emergency authority: The SIP must provide for authority to 
address activities causing imminent and substantial endangerment to 
public health or welfare or the environment and to include contingency 
plans to implement such authorities as necessary.
    The TCAA provides TCEQ with authority to address environmental 
emergencies, and TCEQ has contingency plans to implement emergency 
episode provisions. Upon a finding that any owner/operator is 
unreasonably affecting the public health, safety or welfare, or the 
health of animal or plant life, or property, the TCAA and 30 TAC 
chapters 35 and 118 authorize TCEQ to, after a reasonable attempt to 
give notice, declare a state of emergency and issue without hearing an 
emergency special order directing the owner/operator to cease such 
pollution immediately. The TCEQ may issue emergency orders, or issue or 
suspend air permits as required by an air pollution emergency.
    The ``Texas Air Quality Control Contingency Plan for Prevention of 
Air Pollution Episodes'' is part of the Texas SIP. However, because 8-
hour ozone concentrations in Texas are below 100 ppb, Texas is not 
required to have contingency plans to meet this i-SIP element for the 
2015 O3 NAAQS.\13\ However, to provide additional 
protection, the State has general emergency powers to address any 
possible dangerous air pollution episode

[[Page 18189]]

if necessary to protect the environment and public health.
---------------------------------------------------------------------------

    \13\ See the TSD for more detail.
---------------------------------------------------------------------------

    (H) Future SIP revisions: States must have the authority to revise 
their SIPs in response to changes in the NAAQS, availability of 
improved methods for attaining the NAAQS, or in response to an EPA 
finding that the SIP is substantially inadequate to attain the NAAQS.
    The TCAA authorizes the TCEQ to revise the Texas SIP, as necessary, 
to account for revisions of an existing NAAQS, establishment of a new 
NAAQS, to attain and maintain a NAAQS, to abate air pollution, to adopt 
more effective methods of attaining a NAAQS, and to respond to EPA SIP 
calls concerning NAAQS adoption or implementation.
    (I) Nonattainment areas: The CAA section 110(a)(2)(I) requires that 
in the case of a plan or plan revision for areas designated as 
nonattainment, states must meet applicable requirements of part D of 
the CAA, relating to SIP requirements for designated nonattainment 
areas.
    However, as noted earlier, EPA does not expect infrastructure SIP 
submissions to address CAA section 110(a)(2)(I). The specific SIP 
submissions for designated nonattainment areas, as required under CAA 
title I, part D, are subject to different submission schedules than 
those for section 110 infrastructure elements. Instead, EPA will act on 
any part D attainment plan SIP submissions through a separate 
rulemaking process governed by the requirements for nonattainment 
areas, as described in part D.
    (J) Consultation with government officials, public notification, 
PSD and visibility protection: The SIP must meet the following three 
CAA requirements: (1) Section 121, relating to interagency consultation 
regarding certain CAA requirements; (2) section 127, relating to public 
notification of NAAQS exceedances and related issues; (3) prevention of 
significant deterioration of air quality; and (4) visibility 
protection.
    (1) Interagency consultation: As required by the TCAA, there must 
be a public hearing before the adoption of any regulations or emission 
control requirements, and all interested persons are given a reasonable 
opportunity to review the action that is being proposed and to submit 
data or arguments, either orally or in writing, and to examine the 
testimony of witnesses from the hearing. In addition, the TCAA provides 
the TCEQ the power and duty to establish cooperative agreements with 
local authorities, and consult with other states, the federal 
government and other interested persons or groups in regard to matters 
of common interest in the field of air quality control. Furthermore, 
the Texas PSD SIP rules mandate that the TCEQ shall provide for public 
participation and notification regarding permitting applications to any 
other state or local air pollution control agencies, local government 
officials of the city or county where the source will be located, 
tribal authorities, and Federal Land Manager (FLMs) whose lands may be 
affected by emissions from the source or modification. Additionally, 
the State's PSD SIP rules require the TCEQ to consult with FLMs 
regarding permit applications for sources with the potential to impact 
Class I Federal Areas. The SIP also includes a commitment to consult 
continually with the FLMs on the review and implementation of the 
visibility program. The State recognizes the expertise of the FLMs in 
monitoring and new source review applicability analyses for visibility, 
and has agreed to notify the FLMs of any advance notification or early 
consultation with a new or modifying source prior to the submission of 
a permit application. Likewise, the State's Transportation Conformity 
SIP rules provide for interagency consultation, resolution of 
conflicts, and public notification.
    (2) Public Notification: The i-SIP submission from Texas provides 
the SIP regulatory citations requiring the TCEQ to regularly notify the 
public of instances or areas in which any NAAQS are exceeded. Included 
in the SIP are the rules for TCEQ to advise the public of the health 
hazard associated with such exceedances; and enhance public awareness 
of measures that can prevent such exceedances and of ways in which the 
public can participate in the regulatory and other efforts to improve 
air quality. In addition, as discussed earlier for CAA section 
110(a)(2)(B), the TCEQ air monitoring website provides quality data for 
each of the monitoring stations in Texas; this data is provided 
instantaneously for certain pollutants, such as ozone. The website also 
provides information on the health effects of lead, ozone, particulate 
matter, and other criteria pollutants.
    (3) PSD: The PSD requirements for this element are the same as 
those addressed earlier under CAA section 110(a)(2)(C), Program for 
enforcement of control measures.
    (4) Visibility Protection: The Texas SIP requirements relating to 
visibility protection are not affected when EPA establishes or revises 
a NAAQS. Therefore, EPA believes that there are no new visibility 
protection requirements due to the revision of the NAAQS, and 
consequently there are no newly applicable visibility protection 
obligations pursuant to CAA section 110(a)(2)(J).
    (K) Air quality and modeling/data: The SIP must provide for 
performing air quality modeling, as prescribed by EPA, to predict the 
effects on ambient air quality of any emissions of any NAAQS pollutant, 
and for submission of such data to EPA upon request.
    The TCEQ has the power and duty, under TCAA to develop facts and 
investigate providing for the functions of environmental air quality 
assessment. Past modeling and emissions reductions measures have been 
submitted by the State and approved into the SIP. Additionally, TCEQ 
has the ability to perform modeling for primary and secondary NAAQS on 
a case-by-case permit basis consistent with their SIP-approved PSD 
rules and with EPA guidance.
    The TCAA authorizes and requires TCEQ to cooperate with the federal 
government and local authorities concerning matters of common interest 
in the field of air quality control, thereby allowing the agency to 
make such submissions to the EPA.
    (L) Permitting Fees: The SIP must require each major stationary 
source to pay permitting fees to the permitting authority, as a 
condition of any permit required under the CAA, to cover the cost of 
reviewing and acting upon any application for such a permit, and, if 
the permit is issued, the costs of implementing and enforcing the terms 
of the permit. The fee requirement applies until a fee program 
established by the state pursuant to Title V of the CAA, relating to 
operating permits, is approved by EPA.
    See the earlier discussion for CAA section 110(a)(2)(E) for the 
description of the mandatory collection of permitting fees outlined in 
the SIP.
    (M) Consultation/participation by affected local entities: The SIP 
must provide for consultation and participation by local political 
subdivisions affected by the SIP.
    See the earlier discussions for CAA sections 110(a)(2)(J), elements 
(1) and (2) for a description of the SIP's public participation 
process, the authority to advise and consult, and the PSD SIP's public 
participation requirements. Additionally, the TCAA also requires 
initiation of cooperative action between local authorities and the 
TCEQ, between one local authority and another, or among any combination 
of local authorities and the TCEQ for control of air pollution in areas 
having related air pollution problems that overlap the boundaries of 
political subdivisions,

[[Page 18190]]

and entering into agreements and compacts with adjoining states and 
Indian tribes, where appropriate. The transportation conformity 
component of the Texas SIP requires that interagency consultation and 
opportunity for public involvement be provided before making 
transportation conformity determinations and before adopting applicable 
SIP revisions on transportation-related issues.

Key to Table 1:
A--Proposing to Approve
+--Not germane to infrastructure SIPs
SA--EPA is acting on this infrastructure requirement in a separate
  rulemaking action.

    Based upon review of the State's infrastructure SIP submission and 
relevant statutory and regulatory authorities and provisions referenced 
in this submission or referenced in the EPA-approved Texas SIP, EPA 
believes that Texas has the infrastructure in place to address all 
applicable required elements of CAA sections 110(a)(1) and (2), except 
as noted here, to ensure that the 2015 O3 NAAQS are 
implemented in the State.

IV. 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, EPA's role is to approve state choices, 
provided that they meet the criteria of the CAA. Accordingly, this 
action merely proposes to approve state law as meeting Federal 
requirements and does not impose additional requirements beyond those 
imposed by state law. For that reason, this action:
     Is not a ``significant regulatory action'' subject to 
review by the Office of Management and Budget under Executive Orders 
12866 (58 FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 
2011);
     Is not an Executive Order 13771 (82 FR 9339, February 2, 
2017) regulatory action because SIP approvals are exempted under 
Executive Order 12866;
     Does not impose an information collection burden under the 
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
     Is certified as not having a significant economic impact 
on a substantial number of small entities under the Regulatory 
Flexibility Act (5 U.S.C. 601 et seq.);
     Does not contain any unfunded mandate or significantly or 
uniquely affect small governments, as described in the Unfunded 
Mandates Reform Act of 1995 (Pub. L. 104-4);
     Does not have federalism implications as specified in 
Executive Order 13132 (64 FR 43255, August 10, 1999);
     Is not an economically significant regulatory action based 
on health or safety risks subject to Executive Order 13045 (62 FR 
19885, April 23, 1997);
     Is not a significant regulatory action subject to 
Executive Order 13211 (66 FR 28355, May 22, 2001);
     Is not subject to requirements of section 12(d) of the 
National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 
note) because application of those requirements would be inconsistent 
with the CAA; and
     Does not provide EPA with the discretionary authority to 
address, as appropriate, disproportionate human health or environmental 
effects, using practicable and legally permissible methods, under 
Executive Order 12898 (59 FR 7629, February 16, 1994).
    The SIP is not approved to apply on any Indian reservation land or 
in any other area where EPA or an Indian tribe has demonstrated that a 
tribe has jurisdiction. In those areas of Indian country, the proposed 
rule does not

[[Page 18191]]

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).
