Approval and Promulgation of Implementation Plans; Texas; Control of Emissions of Nitrogen Oxides (NO X ) From Stationary Sources
AGENCY:
Environmental Protection Agency (EPA).
ACTION:
Proposed rule.
SUMMARY:
The EPA is proposing approval of rules for the control of NO X emissions into the Texas State Implementation Plan (SIP). The Texas Commission on Environmental Quality (TCEQ) submitted this revision to the SIP to us on May 30, 2007 (May 30, 2007 SIP revision). The May 30, 2007 SIP revision is a substantive and non-substantive recodification and reformatting of the NO X rules currently approved in the Texas SIP. This revision also includes a part of the NO X reductions needed for the Dallas/Forth Worth (D/FW) area to attain the Federal 8-hour ozone National Ambient Air Quality Standard (NAAQS). This rulemaking covers four separate actions. First, we are proposing to approve the repeal of the current Chapter 117 rules that correspond to the non-substantive new rules and the revised and reformatted rules because the reformatted revision will better accommodate future additions/revisions to the rules. See section 1 of this document. Second, we are proposing to approve revisions to the Texas SIP that add new controls for the D/FW major NO X point sources. We are not, however, taking action on the Texas rules for cement plants in this document. The rules for cement plants are being evaluated in a separate Federal Register document. See sections 5, 6, 13, and 14 of this document. Third, we are proposing to approve revisions to the Texas SIP that add new controls for D/FW minor NO X sources. See section 15 of this document. Fourth, we are proposing to approve revisions to the Texas SIP that add new controls for combustion sources in East Texas. See section 16 of this document. These NO X reductions will assist the D/FW area to attain the 8-hour ozone NAAQS. We are proposing approval of these actions as meeting the requirements of section 110 and part D of the Federal Clean Air Act (the Act).

1. What are we proposing to approve?
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 NO X (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 NO X reductions needed for the D/FW area to attain the Federal 8-hour ozone NAAQS. We are taking four separate actions in this rulemaking action.
First, these revisions involve repealing the current Chapter 117 rules, and simultaneously proposing to approve into the Texas SIP, a new reformatted Chapter 117. We are proposing to approve 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 proposing to approve all of the non-substantive reformatted, restructured, renumbered, reorganized, and administrative revisions to the wording of Chapter 117 into Texas SIP. We want to clarify 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 Texas SIP, Chapter 117's rules we are making it clear that the new rules replace the previous rules in their entirety. We are proposing to approve 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 3 of this document.
Second, we are proposing to approve revisions to the D/FW NO X major point source rules. See sections 5, 6, 13, and 14 of this document. Sections 117.410(a), 117.410(b) and 117.310(b) contain substantive changes in the reformatted Chapter 117 rules that result in additional NO X reductions. These reductions were not previously a part of EPA-approved Texas SIP, Chapter 117.
Third, we are proposing to approve revisions to the D/FW minor source rules for the control of NO X . See section 15 of this document. Sections 117.2010(a) and 117.2110(a) contain substantive changes in the reformatted Chapter 117 rules that result in additional NO X reductions which will help the DFW 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 NO X emissions from combustion sources in East Texas. See section 16 of this document. Sections 117.3310(a) and 117.3010(a) contain substantive changes in the reformatted Chapter 117 rules that result in 22.4 Tons Per Day (TPD) of cumulative NO X reductions. These reductions were not previously a part of EPA-approved Texas SIP, Chapter 117.
Tables 1 and 2 list the section of the Texas rules with significant modifications and minor substantive modifications, respectively. Since Texas has reformatted and recodified the rule, the remaining sections of Chapter 117 are affected by this revision in nonsubstantive ways. Table 3 lists all of the sections that are impacted by this revision both in substantive and in nonsubstantive ways.
Table 1 contains a list of the sections of Chapter 117 with significant modifications. Also see Figure 1 of 30 TAC Chapter 117 at 31 Texas Register 10899, published December 29, 2006.

| Additional data substitution option for major sources subject to MECT | 117.340(c). |
| Expand engine low use requirement from quarterly testing to BPA and D/FW | 117.8140(b). |
| Update references to 101.222 to be consistent with current | 101.222, 117.145(a), 117.245(a), 117.345(a), 117.1045(a), 117.1145(a), 117.1245(a), and 117.3045(a). |
| Clarify compliance schedule for industrial EGFs to submit level of activity information | 117.9020(2)(B). |
For more details on each of these actions, you can refer to our Technical Support Document (TSD) developed in conjunction with this rulemaking action. We are proposing to approve revisions to 30 TAC, Chapter 117, described above as actions one through four, because these revisions to 30 TAC Chapter 117 will enhance the Texas SIP for controlling NO X emissions from stationary sources and the NO X emission reductions will assist the D/FW area to attain the 1997 8-hour ozone NAAQS. Furthermore, approving the non-substantive changes will maintain consistency between the State rules and Federal SIP.
2. What is the relationship between the May 30, 2007 SIP revision and the ozone attainment demonstration plan for the D/FW?
The resulting emissions reductions of NO X , an ozone precursor, from this SIP revision will assist in bringing the D/FW area into attainment with the 8-hour ozone NAAQS, and help with the maintenance of the ozone NAAQS in the East and Central parts of the State. We will be reviewing the 8-hour ozone attainment demonstration plan in a separate rulemaking action.
3. What sections of the May 30, 2007, SIP revision will become part of Texas SIP?
Table 3 below contains a summary list of the sections of 30 TAC, Chapter 117 that Texas submitted on May 30, 2007, for point sources of NO X that we are proposing become part of the Texas SIP. Table 3 includes both the sections with substantive changes and the nonsubstantive changes.

4. What sections of the May 30, 2007, SIP revision will not become part of the Texas SIP?
Per TCEQ's request the following sections, listed in Table 4 below, of the May 30, 2007, SIP revision will not become a part of the EPA-approved Texas SIP. 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 4 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 |
|---|---|
| 117.110(c), 117.125, 117.210(c), 117.225,117.310(c), 117.325, 117.410(d), 117.425,117.1010(b), 117.1025, 117.1110(b),117.1125, 117.1210(b), 117.1225,117.1310(b), 117.1325, 117.2010(i), 117.2025, 117.2110(h), 117.2125, 117.3010(e), 117.3025, 117.3123(f), 117.3125, 117.3310(e), and 117.3325 | Not a part of EPA-approved Texas SIP and TCEQ continues to ask that these rules remain outside the SIP. |
Although the above sections of 30 TAC Chapter 117 are not to become a part of the Texas SIP they will continue to remain enforceable at the State level.
5. What sections of the May 30, 2007 SIP revision are we not acting upon in this proposal?
We are not evaluating the cement kiln related sections of the May 30, 2007 SIP revision, in this document. See Table 5 below. We will review and act upon the cement kiln related sections of the May 30, 2007 SIP revision in a separate rulemaking action.
| Section No. | Explanation |
|---|---|
| 117.3100, 117.3101, 117.3103, 117.3110, 117.3120, 117.3123, 117.3125, 117.3140, 117.3142, and 117.3145 | Cement kiln related, not evaluating in this rulemaking action. |
6. What Counties in the D/FW area will the May 30, 2007 SIP revision affect?
Table 6 below lists the Counties in the D/FW 8-hour ozone nonattainment area that will be affected by the May 30, 2007 SIP revision.
| D/FW Counties | Explanation |
|---|---|
| Collin, Dallas, Denton, Ellis, Johnson, Kaufman, Parker, Rockwall, and Tarrant | See section 117.10(2)(C). |
7. What Counties in East and Central Texas will the May 30, 2007 SIP revision affect?
Table 7 below lists the Counties in the East and Central Texas that will be affected by the May 30, 2007 SIP revision.
| East and Central Texas counties | Explanation |
|---|---|
| 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, Titus, Upshur, Van Zandt, and Wood | See section 117.10(14)(B). |
8. 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 NO X and VOCs in the presence of sunlight and high ambient temperatures. Thus, ozone is known primarily as a summertime air pollutant. NO X and VOCs are precursors of ozone. Motor vehicle exhaust and industrial emissions, gasoline vapors, chemical solvents and natural sources emit NO X 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.
9. What are NO X ?
Nitrogen oxides belong to the group of criteria air pollutants. NO X 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. Also see http://www.epa.gov/air/urbanair/nox/.
10. 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.
11. What areas in Texas will today's rulemaking action affect?
The substantive rule revisions we are proposing to approve today mainly affect the D/FW 8-hour ozone nonattainment area. See section 6 of this document. The substantive rule revisions we are proposing to approve today also affect 33 counties in East and Central Texas. See section 7 of this document. If you are in one of these affected areas, you should refer to the Texas NO X rules to determine if and how today's action will affect you.
As stated elsewhere in this document 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 April 30, 2004.
12. What is the section 110(l) "anti-backsliding" analysis for the May 30, 2007 SIP revision?
According to section 110(l) of the Act "each revision to an implementation plan submitted by a State under this Act shall be adopted by such State after reasonable notice and public hearing. The Administrator shall not approve a revision of a plan if the revision would interfere with any applicable requirement concerning attainment and reasonable further progress (as defined in section 171), or any other applicable requirement of this Act."
• The May 2007 SIP submittal includes documentation that the State has met and complied with the reasonable notice and public hearing requirements. The State held public hearings after proper notice and according to the 40 CFR 51.102 requirements. Proper notice included prominent advertisement in the areas affected at least 30 days prior to the dates of the hearings. The hearing notices of intended action were circulated to the public, including interested persons, EPA Region 6, and all applicable local air pollution control agencies. Public hearings were held in Houston, Dallas, Arlington, Midlothian, Longview, and Austin, Texas. The May 2007 SIP submittal contains information to the effect that State has met and complied with the reasonable notice and public hearing requirements. For more information see our SIP Completeness Determination document, prepared in accordance with the Appendix V of 40 CFR 51, made part of the EPA-R06-OAR-2007-0523 docket, and available for public review. Therefore, it is our finding that this revision submitted by Texas under the Act has been adopted by Texas after reasonable notice and public hearing.
• The May 2007 SIP submittal requires NO X reductions from sources located outside the D/FW nine-County area. The resulting NO X reductions should assist in bringing the D/FW area into attainment with the 8-hour ozone NAAQS. Sources outside the D/FW nine county area, now regulated by these rules include, gas-fired stationary reciprocating internal combustion engines operating in East Texas (see 117.3310(a) and 117.3010(a)). NO X emissions from these units were not regulated before. These units are located in Texas Counties that are designated as attainment for ozone NAAQS. These Texas Counties are 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, and Wood. It is estimated that these revisions will result in 22.4 TPD of NO X reductions.
• The May 2007 SIP submittal provides for additional NO X emissions reductions that were not previously a part of the EPA-approved Texas SIP. The May 2007 SIP submittal requires NO X reductions from major sources or major source categories not previously regulated. An example listing of such sources or categories is as follows: stationary diesel engines in the D/FW nine-County area (see 117.410(b)(4)), stationary reciprocating internal combustion engines located in theD/FW nine county area (see 117.410(a) and (b)), metallurgical furnaces (see 117.410(b)(8)), container glass furnaces (see 117.410(b)(10)(A)), and fiberglass furnaces (see 117.410(b)(10)(B) through (D)). These new regulations provide an additional 8.88 tons/day of reductions.
• The May 2007 SIP submittal provides for additional NO X emissions reductions that were not previously a part of the EPA-approved Texas SIP. The May 2007 SIP submittal requires NO X reductions from minor sources within the DFW nine county area not previously regulated. See 117.2110(a)(1), and 117.2010(a)(1) and (2). These rules provide additional NO X emissions reductions that were not previously a part of the EPA-approved Texas SIP. See section 15 of this document.
• The statewide residential water heater rule was revised due to technical infeasibility which means this rule will achieve slightly less reductions than if the approved rule had proved feasible. We believe this small loss in emission reductions will be offset by other measures. This is further discussed in the Technical Support Document. We have discussed the potential impact of the revised water heater rule in our separate action on the 1997 8-hour ozone attainment demonstration for the D/FW area. In that action we explain how the revisions do not interfere with attainment or maintenance of the NAAQS.
For the reasons stated above, the provisions of the May 2007 SIP submittal meet the section 110(l) requirements of the Act.
13. What are the NO X emissions requirements for major point sources in the D/FW area that we are proposing to approve?
We approved NO X emissions specifications for stationary sources in 66 FR 15195 published March 16, 2001. In addition to requiring NO X emissions control requirements for those sources, we are proposing to approve the following NO X 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 8 below for reference purposes.

The tables in this document are not intended to be exhaustive, but rather provide a guide for readers regarding NO X control requirements the affected sources are likely to be required to comply with 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). We are proposing approval of these NO X emissions specifications under Part D of the Act because their resulting emissions reductions will assist Texas in demonstrating attainment of the 8-hour ozone standard in the D/FW 8-hour ozone nonattainment area. Therefore, we are proposing approval of these requirements into the Texas SIP.
14. What are the NO X emission requirements for stationary diesel engines in the D/FW area that we are proposing to approve?
This SIP revision requires reductions of NO X emissions from stationary diesel engines in the D/FW area. The following Table 9 contains a summary of the NO X 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 9 below for convenience purposes.
| Source | NO X Emission Specification | Citation |
|---|---|---|
| Diesel engines in service before March 1, 2009: not modified, reconstructed, or relocated on or after March 1, 2009 | 11.0 gram/hp-hr | 117.410(b)(4)(D). |
| Rated less than 50 hp: modified, installed reconstructed, or relocated on or after March 1, 2009 | 5.0 gram/hp-hr | 117.410(b)(4)(E)(i). |
| 50 hp [ rated 100 hp: modified, installed, reconstructed, or relocated on or after March 1, 2009 | 3.3 gram/hp-hr | 117.410(b)(4)(E)(ii). |
| 100 hp [ rated 750 hp: installed, modified, reconstructed, or relocated on or after March 1, 2009 | 2.8 gram/hp-hr | 117.410(b)(4)(E)(iii). |
| Rated = 750 hp: installed, modified, reconstructed, or relocated on or after March 1, 2009 | 4.5 gram/hp-hr | 117.310(b)(4)(E)(iv). |
We are proposing to approve the above-listed NO X emission requirements for diesel engines because they are in agreement with those found in 40 CFR section 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 NO X 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 proposing approval of these NO X emission requirements 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. Therefore, we are proposing approval of these requirements into the Texas SIP.
15. What are the emissions specifications for minor sources of NO X in D/FW area that we are proposing to approve?
These minor sources include stationary reciprocating internal combustion engines that are not a major source of NO X (emit, when uncontrolled, less than 50 Tons Per Year (TPY) of NO X ). See sections 117.2100 and 117.2103 for more information.
| Source | NO X emission specification | Additional information | Citation |
|---|---|---|---|
| Reciprocating Internal Combustion Engines | 0.60 g/hp-hr | Stationary, rich-burn, using landfill gas-fired | 117.2110(a)(1)(A)(i). |
| Reciprocating Internal Combustion Engines | 0.50 g/hp-hr | Stationary, rich-burn, not landfill gas-fired | 117.2110(a)(1)(A)(ii). |
| Reciprocating Internal Combustion Engines | 0.70 g/hp-hr | Stationary, lean-burn, in service before June 1, 2007 | 117.2010(a)(1)(B)(i). |
| Reciprocating Internal Combustion Engines | 0.60 g/hp-hr | Stationary, lean-burn, in service on or after June 1, 2007, using landfill gas | 117.2010(a)(1)(B)(i)(I). |
| Reciprocating Internal Combustion Engines | 0.50 g/hp-hr | Stationary, lean-burn, in service on or after June 1, 2007, not using landfill gas | 117.2010(a)(1)(B)(i)(II). |
| Reciprocating Internal Combustion Engines | 5.83 g/hp-hr | Stationary, dual-fuel | 117.2010(a)(2). |
As an alternative, a minor source from the Table 10 above located within the D/FW 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 NO X emissions requirements for the above-listed minor sources of NO X 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 proposing approval of these requirements into the Texas NO X SIP.
16. What are the NO X emissions requirements for stationary RICE in East Texas that we are proposing to approve?
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 11 contains NO X 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 NO X from existing stationary gas-fired rich-burn compressor engines. For more information see http://www.tceq.state.tx.us/implementation/air/rules/sb2003.html (URL dating July 20, 2007).
| Source | NO X Emission specification | Additional information | Citation |
|---|---|---|---|
| Reciprocating Internal Combustion Engines | 1.00 g/hp-hr | Rich burn, gas-fired, capacity 500 hp | 117.3310(a)(1). |
| Reciprocating Internal Combustion Engines | 0.60 g/hp-hr | Rich burn, landfill gas-fired, capacity = 500 hp | 117.3010(a)(2)(A). |
| Reciprocating Internal Combustion Engines | 0.50 g/hp-hr | Rich burn, not landfill gas-fired, capacity = 500 hp | 117.3010(a)(2)(B). |
The NO X 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 proposing approval of these requirements into the May 30, 2007 Texas SIP under part D, and sections 110 and 116 of the Act, respectively.
17. What are the compliance schedules for NO X emissions sources that we are proposing to approve?
The following Table 12 contains a summary of the NO X -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.
| Source | Compliance date | Additional information | Citation |
|---|---|---|---|
| Major, D/FW | Install all NO X abatement equipment by no later than May 30, 2007 | Increment of Progress (IOP) requirement | 117.9030(a)(1). |
| Major, D/FW | Submit initial control plan per 117.450 by no later than June 1, 2008. | 8-hour attainment demonstration | |
| Comply with emissions requirements by no later than March 1, 2009 when source subject to117.410(b)(1), (2), (4), (5), (6), (7)(A), (10), and (14) | Requirement | 117.9030(b). | |
| Diesel and dual-fuel engines comply with testing and hours of operation for testing and maintenance by no later than March 1, 2009 | |||
| Gas turbines or IC engines claiming run time exemption comply with the run time requirements by no later than March 1, 2009 | |||
| D/FW | Submit initial control plan per117.1350 by no later than June 1, 2008 | Utility electric generation sources | 117.9130(a)(1) and (2). |
| Comply with all other requirements by no later than March 1, 2009 | |||
| Minor, D/FW | Rich-burn, gas-fired stationary RICE comply with NO X requirements by no later than March 1, 2009 | RICE fired with different fuel types | 117.9210. |
| Lean-burn, gas-fired stationary RICE comply with NO X requirements by no later than March 1, 2010 | |||
| Diesel-fired and dual-fuel stationary RICE comply with NO X requirements by no later than March 1, 2009 | |||
| East and Central Texas | Updated final control plan per117.3054 be submitted by no later than January 31, 2007 | Utility electric generation sources | 117.9300(2)(B). |
| East Texas | Stationary RICE comply with NO X requirements by no later than March 1, 2010 | East Texas combustion sources | 117.9340(a). |
Including these compliance dates, summarized in Table 12 above, in the rule provides for enforceability and practicability of the NO X rule, and enhances the May 30, 2007 Texas SIP; therefore, we are proposing their approval into the May 30, 2007 Texas SIP.
III. Proposed Actions
Today, we are proposing to approve revisions to the 30 TAC Chapter 117 into the Texas SIP. This rulemaking covers four separate actions. First, we are proposing to approve 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 proposing to approve substantive revisions to the current NO X SIP's Chapter 117 rules for D/FW NO X major point sources. Third, we are proposing to approve substantive revisions to the current Texas SIP's Chapter 117 rules for D/FW minor sources of NO X . Fourth, we are proposing to approve substantive revisions to the current Texas SIP's Chapter 117 rules for combustion sources in East Texas. These NO X reductions will assist the D/FW area in attaining the 8-hour ozone NAAQS.
IV. 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 proposed 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 proposed 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 (Public Law 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 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 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.
