AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

The EPA is proposing approval of rules for the control of NOX emissions into the Texas State Implementation Plan (SIP). The Texas Start Printed Page 39901Commission 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 NOX rules currently approved in the Texas SIP. This revision also includes a part of the NOX 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 NOX 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 NOX 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 NOX 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).

DATES:

Comments must be received on or before August 11, 2008.

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 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. 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 NOX 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 NOX 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 NOX. 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 NOX 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 NOX 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 NOX 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.

Clarify compliance schedule for industrial EGFs to submit level of activity information117.9020(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 NOX emissions from stationary sources and the NOX 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 NOX, 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 NOX 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 117.3325Not 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.

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 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.

9. 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. 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 NOX 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 NOX reductions from sources located outside the D/FW nine-County area. The resulting NOX 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)). NOX 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, Start Printed Page 39908Hunt, 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 NOX reductions.
  • The May 2007 SIP submittal provides for additional NOX emissions reductions that were not previously a part of the EPA-approved Texas SIP. The May 2007 SIP submittal requires NOX 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 the D/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 NOX emissions reductions that were not previously a part of the EPA-approved Texas SIP. The May 2007 SIP submittal requires NOX 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 NOX 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 NOX emissions requirements for major point sources in the D/FW area that we are proposing to approve?

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 proposing to approve 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 8 below for reference purposes.

The tables in this document are not intended to be exhaustive, but rather provide a guide for readers regarding NOX 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 NOX 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 NOX emission requirements for stationary diesel engines in the D/FW area that we are proposing to approve?

This SIP revision requires reductions of NOX emissions from stationary diesel engines in the D/FW area. The following Table 9 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 9 below for convenience purposes.

Rated ≥ 750 hp: installed, modified, reconstructed, or relocated on or after March 1, 20094.5 gram/hp-hr117.310(b)(4)(E)(iv).

We are proposing to approve the above-listed NOX 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 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 proposing approval of these NOX 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 NOX 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 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 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 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 proposing approval of these requirements into the Texas NOX SIP.

16. What are the NOX 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 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/​sb2003.html (URL dating July 20, 2007).

Reciprocating Internal Combustion Engines0.50 g/hp-hrRich burn, not landfill gas-fired, capacity ≥ 500 hp117.3010(a)(2)(B).

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 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 NOX emissions sources that we are proposing to approve?

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.

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 NOX SIP's Chapter 117 rules for D/FW NOX 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 NOX. Fourth, we are proposing to approve 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 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.
