[EPA-R06-OAR-2007-0523; FRL-8747-6]

Approval and Promulgation of Implementation Plans; Texas; Control
of Emissions of Nitrogen Oxides (NOX) From Stationary Sources

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: The EPA is finalizing approval of rules for the control of
NOX emissions into the Texas State Implementation Plan
(SIP). Texas submitted this SIP revision to us on May 30, 2007 (May 30,
2007 SIP revision), and we proposed approval of the May 30, 2007 SIP
revision on July 11, 2008. The May 30, 2007 SIP revision to the Texas
SIP is a substantive and non-substantive recodification and
reformatting of the NOX rules currently approved in the
Texas SIP, and also includes a part of the Nitrogen Oxides
(NOX ) reductions needed for the Dallas/Forth Worth (D/FW)
area to attain the Federal 8-hour ozone National Ambient Air Quality
Standard (NAAQS). Today's final rulemaking covers four separate
actions. First, we are approving the repeal, from the Texas SIP, of the
current Chapter 117 rules that correspond to the re-codified new rules
and the revised and reformatted rules because the reformatted revision
will better accommodate future additions/revisions to the rules.
Second, we are approving revisions to the Texas SIP that add new
controls for the D/FW major NOX point sources. We are not,
however, taking action on the Texas rules for cement plants in this
document. We proposed approval of the rules for cement plants in a
separate Federal Register document. Third, we are approving revisions
to the Texas SIP that add new controls for D/FW minor NOX
sources. Fourth, we are approving revisions to the Texas SIP that add
new controls for combustion sources in East Texas. These NOX
reductions will assist the D/FW area to attain the 8-hour ozone NAAQS.
We are approving all of these actions as meeting the requirements of
section 110 and part D of the Federal Clean Air Act (the Act).

DATES: This rule will be effective on January 2, 2009.

ADDRESSES: The EPA has established a docket for this action under
Docket ID No. EPA-R06-OAR-2007-0523. All documents in the docket are

I. Background

A. What actions are we approving?

    On May 30, 2007, TCEQ submitted rule revisions to 30 TAC, Chapter
117, ``Control of Air Pollution from Nitrogen Compounds,'' as a
revision to the Texas SIP for point sources of NOX (May 30,
2007 SIP revision). The State of Texas submitted the May 30, 2007 SIP
revision to us, to, among other things, provide a portion of the
NOX reductions needed for the D/FW area to attain the
Federal 8-hour ozone NAAQS.
    On July 11, 2008 (73 FR 39900) we proposed approval of the May 30,
2007 SIP revision. The public comment period for our proposal expired
on August 11, 2008.
    We received relevant comments from TCEQ on our July 11, 2008 (73 FR
39900) publication, correcting or clarifying some of the citations used
in our proposed approval document. We appreciate the State's input, and
have accordingly corrected those citations in today's final document.
See our Technical Support Document (TSD) prepared in conjunction with
today's final action for more information.
    We received no other comments on our proposed approval of the May
30, 2007 SIP revision. Therefore, we are finalizing our July 11, 2008
proposal (73 FR 39900), except section 117.9810, rulemaking action,
today. We will act on section 117.9810 in a separate rulemaking action
in future \1\. We are taking four separate actions in today's final
action.
---------------------------------------------------------------------------

    \1\ It came to our attention after publication of the proposal
that we never took action on 30 TAC 117.571 that TCEQ repealed, and
replaced with a new 30 TAC 117.9810. Therefore, there is no
previously approved rule in the Texas SIP. We will need to evaluate
the new rule 30 TAC 117.9810 for substance, and determine if it is
approvable as a SIP revision. Our action will be taken in a separate
Federal Register rulemaking.
---------------------------------------------------------------------------

    First, we are approving revisions which involve repealing the
current Chapter 117 rules from Texas SIP, and simultaneously approving
into the Texas SIP, a new reformatted Chapter 117. We are approving the
repeal of the current Chapter 117, and the recodification and
reformatting of Chapter 117 because the reformatted revision will
better accommodate future additions/revisions to the rules and will
maintain consistency between the State rules and Federal SIP. We are
approving all of the non-substantive reformatted, restructured,
renumbered, reorganized, and administrative revisions to the wording of
Chapter 117 into Texas SIP. In our proposal, we clarified that the
specifically identified rules do not make any changes to the substance
of the rules that we previously approved into the Texas SIP, Chapter
117. By approving the repeal of the current Chapter 117 from the Texas
SIP, and approving the new Chapter 117's rules into the Texas SIP, we
are making it clear that the new rules replace the previous rules in
their entirety. We are approving these non-substantive reformatted,
restructured, renumbered, reorganized, and administrative revisions to
the wording of Chapter 117 under section 110 and part D of the Act. For
a full list of affected sections see section C of this document.
    Second, we are approving revisions to the D/FW NOX major
point source rules. Sections 117.410(a), 117.410(b) and 117.310(b)
contain substantive changes in the reformatted Chapter 117 rules that
result in additional NOX reductions. These reductions were
not previously a part of EPA-approved Texas SIP, Chapter 117.
    Third, we are approving revisions to the D/FW minor source rules
for the control of NOX. Section 117.2110(a) contains
substantive changes in the reformatted Chapter 117 rules that result in
additional NOX reductions which will help the D/FW area to
attain the 1997 8-hour ozone standard. These reductions were not
previously a part of EPA-approved Texas SIP, Chapter 117.
    Fourth, we are proposing to approve revisions to the rules for the
control of NOX emissions from combustion sources in East
Texas. Section 117.3310(a) contains substantive changes in the
reformatted Chapter 117 rules that result in significant NOX
emissions reductions. These reductions were not previously a part of
EPA-approved Texas SIP, Chapter 117.
    Sections F through P of this document contain more information
concerning each of these four actions.

B. What is the relationship between the May 30, 2007 SIP revision and
the ozone attainment demonstration plan for the D/FW area?

    The resulting emissions reductions of NOX, an ozone
precursor, from this SIP revision will assist in bringing the D/FW area
into attainment with the 1997 8-hour ozone NAAQS, and help with the
maintenance of the 1997 ozone NAAQS in the East and Central parts of
the State. The D/FW 8-hour ozone nonattainment area (Collin, Dallas,
Denton, Tarrant, Ellis, Johnson, Kaufman, Parker, and Rockwall
Counties) is designated nonattainment, and classified as a moderate 8-
hour non-attainment area for ozone. See 69 FR 23857 published on April
30, 2004. We proposed approval of the D/FW 8-hour ozone attainment
demonstration plan in a separate rulemaking action, and will consider
relevant written comments received on the D/FW 8-hour ozone attainment
demonstration plan in a separate Federal Register publication.

C. What sections of the May 30, 2007, SIP revision will become part of
Texas SIP?

    Table 1 below contains a summary list of the sections of 30 TAC,
Chapter 117 that we proposed for approval, in our July 11, 2008 (73 FR
39900) rulemaking action, for point sources of NOX to become
part of the Texas SIP. Table 1 below includes both the sections with
substantive changes and the nonsubstantive changes.

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

    Although we proposed approval of the new section 117.9810
concerning Use of Emission Reductions Generated from the Texas
Emissions Reduction Plan (TERP) in our July 11, 2008 publication, we
are taking no action upon 117.9810 today. We will take rulemaking
action on 117.9810 in a separate publication in future.
    Please keep in mind that the tables in this document are not
intended to be exhaustive, but rather to provide a guide for readers to
generally understand which affected sources are likely to be required
to comply with the NOX control requirements in conjunction
with today's rulemaking action. To determine whether or how your
facility would be affected by this particular action, you should refer
to the actual text of 30 TAC Chapter 117, and the June 8, 2007 issue of
the Texas Register (32 TexReg 3206). You can find the entire TCEQ
Chapter 117 rules at: http://www.tceq.state.tx.us/rules/
indxpdf.html#117.
    Our TSD prepared for the July 11, 2008 (73 FR 39900) proposal
contained detailed discussion of each of the above changes, and why EPA
believed they should be approved into Texas SIP. We are approving the
above sections of Table 1 into Texas SIP.

D. What sections of the May 30, 2007, SIP revision will not become part
of Texas SIP?

    Per TCEQ's request the following sections, listed in Table 2 below,
of the May 30, 2007, SIP revision will not become a part of the EPA-
approved Texas SIP. As stated in our proposal these rules mainly
pertain to the control of ammonia or carbon monoxide emissions which
are not ozone precursors and therefore, these rules are not necessary
components of the Texas SIP. The rules listed in Table 2 are not
already in the current Texas SIP and EPA continues to agree with Texas
that these rules can remain outside the SIP.

------------------------------------------------------------------------
                 Section No.                          Explanation

 117.310(c), 117.325, 117.410(d), 117.425,      approved Texas SIP, and
 117.1010(b), 117.1025, 117.1110(b),            TCEQ continues to ask
 117.1125, 117.1210(b), 117.1225,               that these rules remain
 117.1310(b), 117.1325, 117.2010(i),            outside the SIP.
 117.2025, 117.2110(h), 117.2125,
 117.3010(2), 117.3025, 117.3123(f),
 117.3125, 117.3310(e), and 117.3325.
------------------------------------------------------------------------

    Although the above sections of 30 TAC Chapter 117 will not become a
part of the Texas SIP, they will continue to remain enforceable at the
State level. As stated elsewhere in this document, we are taking no
action upon 117.9810 today. We will take rulemaking action on 117.9810
in a separate publication in future.

E. What sections of the May 30, 2007, SIP revision are we reviewing in
another Federal Register action?

    Table 3 below contains a listing of sections of the May 30, 2007,
SIP revision that we are not finalizing in today's action. We will
review and act upon the cement kiln related sections of the May 30,
2007 SIP revision in a separate rulemaking action.

H. What are NOX?

    Nitrogen oxides belong to the group of criteria air pollutants.
NOX are produced from burning fuels, including gasoline and
coal. Nitrogen oxides react with volatile organic compounds (VOC) to
form ozone or smog, and are also major components of acid rain. For
more information on NOX see http://www.epa.gov/air/urbanair/
nox/.

I. What is Ozone and why do we regulate it?

    Ozone is a gas composed of three oxygen atoms. Ground level ozone
is generally not emitted directly from a

vehicle's exhaust or an industrial smokestack, but is created by a
chemical reaction between NOX and VOCs in the presence of
sunlight and high ambient temperatures. Thus, ozone is known primarily
as a summertime air pollutant. NOX and VOCs are precursors
of ozone. Motor vehicle exhaust and industrial emissions, gasoline
vapors, chemical solvents and natural sources emit NOX and
VOCs. Urban areas tend to have high concentrations of ground-level
ozone, but areas without significant industrial activity and with
relatively low vehicular traffic are also subject to increased ozone
levels because wind carries ozone and its precursors hundreds of miles
from their sources.
    Repeated exposure to ozone pollution may cause lung damage. Even at
very low concentrations, ground-level ozone triggers a variety of
health problems including aggravated asthma, reduced lung capacity, and
increased susceptibility to respiratory illnesses like pneumonia and
bronchitis. It can also have detrimental effects on plants and
ecosystems.

J. What is a SIP?

    The SIP is a set of air pollution regulations, control strategies,
other means or techniques and technical analyses developed by the
state, to ensure that the state meets the NAAQS. The SIP is required by
section 110 and other provisions of the Act. These SIPs can be
extensive, containing state regulations or other enforceable documents
and supporting information such as emissions inventories, monitoring
networks, and modeling demonstrations. Each state must submit these
regulations and control strategies to EPA for approval and
incorporation into the Federally-enforceable SIP. Each Federally-
approved SIP protects air quality primarily by addressing air pollution
at its point of origin.

K. What are the NOX emissions requirements for point sources
in the D/FW area that we are approving?

    We approved NOX emissions specifications for stationary
sources in 66 FR 15195 published March 16, 2001. In addition to
requiring NOX emissions control requirements for those
sources, we are approving the following NOX emissions
requirements for the following affected sources with emissions greater
than 50 Tons Per Year (TPY) in the D/FW 8-hour ozone nonattainment
area. We have included the Chapter 117 citation for each source
category in the Table 6 below for convenience purposes.

    We are approving these NOX emissions specifications
under Part D of the Act because their resulting emissions reductions
will assist Texas in demonstrating attainment of the 1997 8-hour ozone
standard in the D/FW 8-hour ozone nonattainment area. Therefore, we are
approving these requirements into the Texas SIP.

L. What are the NOX emission requirements for stationary
diesel engines in the D/FW area that we are approving?

    This SIP revision requires reductions of NOX emissions
from stationary diesel engines in the D/FW area. The following Table 7
contains a summary of the NOX emission specifications for
stationary diesel engines in the D/FW area. We have included the
Chapter 117 citation for each source category in the Table 7 below for
convenience purposes.

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

    Also see section 117.2110(a)(3) concerning stationary diesel
engines at minor sources within the D/FW 8-Hour Ozone Nonattainment
Area.
    As stated in our July 11, 2008 (73 FR 39900) proposal, we are
approving the above-listed NOX emission requirements for
diesel engines because they are in agreement with those found in 40 CFR
89.112, and EPA's Document Number 420-R-98-016 dated August 1998,
titled ``Final Regulatory Impact Analysis: Control of Emissions from
Nonroad Diesel Engines.'' In addition, the above-listed NOX
emission requirements for diesel engines are consistent with those we
approved for similar units at Table VI of 66 FR 57230 published on
November 14, 2001. We are therefore approving these NOX
emission requirements into the Texas SIP under Part D of the Act
because their resulting emissions reductions will assist Texas in
demonstrating attainment of the 8-hour ozone standard within the D/FW
8-hour ozone nonattainment area.

M. What are the NOX emissions specifications for minor
sources of NOX in the D/FW area that we are approving?

    These minor sources include stationary reciprocating internal
combustion engines that are not a major source of NOX (emit,
when uncontrolled, less than 50 Tons Per Year (TPY) of NOX).
See sections 117.2100 and 117.2103 for more information.

    As an alternative, a minor source from the Table 8 above located
within the D/FW area and having an annual capacity factor of 0.0383 or
less may choose emissions specification of 0.060 lb/MMBtu, instead. See
117.2110(a)(4).
    The NOX emissions requirements for the above-listed
minor sources of NOX and their resulting emissions
reductions will assist in demonstrating attainment of the 8-hour ozone
NAAQS within the D/FW 8-hour ozone nonattainment area. Therefore, we
are approving these requirements into the Texas SIP.

N. What are the NOX emissions requirements for stationary
reciprocating internal combustion engines (RICE) in East Texas that we
are approving?

    The gas-fired stationary reciprocating internal combustion engines
located in Anderson, Brazos, Burleson, Camp, Cass, Cherokee, Franklin,
Freestone, Gregg, Grimes, Harrison, Henderson, Hill, Hopkins, Hunt,
Lee, Leon, Limestone, Madison, Marion, Morris, Nacogdoches, Navarro,
Panola, Rains, Robertson, Rusk, Shelby, Smith, Upshur, Van Zandt, or
Wood Texas Counties are subject to these requirements. See section
117.3300 for more information. The following Table 9 contains
NOX emissions requirements and related information for these
affected units.
    On July 19, 2007 TCEQ announced implementation of Texas Senate Bill
2000, passed in 2007 by the 80th Texas Legislative Session. The Bill
directs the TCEQ to develop an incentive grant program for the partial
reimbursement of capital costs for installing nonselective catalytic
reduction (NSCR) systems to reduce emissions of NOX from
existing stationary gas-fired rich-burn compressor engines. For more
information see http://www.tceq.state.tx.us/implementation/air/rules/

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

    The NOX emissions requirements for the stationary
reciprocating internal combustion engines in East and Central Texas and
their resulting emissions reductions will assist in demonstrating
attainment of the 8-hour ozone NAAQS within the Houston-Galveston-
Brazoria, D/FW, and Beaumont/Port Arthur areas. Furthermore, these
reductions will contribute to the continued maintenance of the standard
in the eastern half of the State of Texas, and they enhance the Texas
SIP. Therefore, we are approving these requirements into the Texas SIP
under part D, and sections 110 and 116 of the Act, respectively.

O. What are the NOX emissions requirements for state-wide
water heaters, small boilers, and process heaters that we are
approving?

    The water heaters, small boilers, and process heaters that use
natural gas and have a rated capacity of 2 million Btu per hour or less
are subject to these requirements. See 117.3200 and 117.3203 for more
information. The following Tables 10 and 11 contain type and size
categories, and NOX emissions requirements for these
affected units.

    The size categories and NOX emissions requirements for
these affected units are similar to those in place in other parts of
the country. In our proposal and the corresponding TSD we explained how
the revised state-wide residential water heater NOX emission
requirements meet the requirements of section 110(l) of the Act.
Therefore, we are finding that the revised state-wide residential water
heater NOX emission requirements meet section 110(l) of the
Act. Thus, we are approving the state-wide NOX emission
requirements for water heaters, small boilers, and process heaters into
the Texas SIP.

P. What are the compliance schedules for NOX emissions
sources that we are approving?

    The following Table 12 contains a summary of the NOX-
related compliance schedules for major sources, utility generating
units, and minor sources affected by the May 30, 2007 SIP revision. See
sections 117.9000 through 117.9500 for more information.

    Including these compliance dates, summarized in Table 12 above, in
the rule provides for enforceability and practicability of the
NOX rule, and enhances the Texas SIP; therefore, we are
approving them into the Texas SIP.

II. Final Action

    Today, we are finalizing approval of revisions to the 30 TAC
Chapter 117 into the Texas SIP. This rulemaking covers four separate
actions. First, we are approving the repeal of all non-substantive
changes to the SIP's Chapter 117 rules and the reformatting of current
Chapter 117 because the reformatted revision will better accommodate
future additions/revisions to the rules. Second, we are approving
substantive revisions to the current NOX SIP's Chapter 117
rules for D/FW NOX major point sources. Third, we are
approving substantive revisions to the current Texas SIP's Chapter 117
rules for D/FW minor sources of NOX . Fourth, we are
approving substantive revisions to the current Texas SIP's Chapter 117
rules for combustion sources in East Texas. These NOX
reductions will assist the D/FW area in attaining the 1997 8-hour ozone
NAAQS. Today, we are not taking action on the cement kiln related
provisions of Chapter 117, see sections E and D of this document. We
are also not taking action on new section 117.9810, see section C of
this document.

III. 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 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 Order
12866 (58 FR 51735, October 4, 1993);
     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;
     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); and
     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.
    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. EPA will 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 February 2, 2009. 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 section 307(b)(2).)
