ACTION: Direct final rule. AGENCY: SUMMARY: On January 20, 2006, the Texas Commission on Environmental Quality (TCEQ) submitted a State Implementation Plan (SIP) revision to request redesignation of the El Paso carbon monoxide (CO) nonattainment area to attainment for the CO National Ambient Air Quality Standard (NAAQS). This submittal also included a CO maintenance plan for the El Paso area and associated Motor Vehicle Emission Budgets (MVEBs). The maintenance plan was developed to ensure continued attainment of the CO NAAQS for a period of 10 years from the effective date of EPA approval of redesignation to attainment. In this action, EPA is approving the El Paso CO redesignation request and the maintenance plan with its associated MVEBs as satisfying the requirements of the Federal Clean Air Act (CAA) as amended in 1990.

EPA’s Evaluation of the El Paso Redesignation Request and Maintenance Plan III. EPA’s Evaluation of the Transportation Conformity Requirements IV. Consideration of Section 110(l) of the CAA V. Final Action VI. Statutory and Executive Order Reviews jlentini on PROD1PC65 with RULES I. Background Under the 1990 Federal Clean Air Act (CAA) Amendments, El Paso was designated and classified as a moderate nonattainment area for CO because it did not meet the 8-hour CO NAAQS for this criteria pollutant (56 FR 56694). El Paso’s classification as a moderate nonattainment area under sections 107(d)(4)(A) and 186(a) of the CAA imposed a schedule for attainment of the CO NAAQS by December 31, 1995. The El Paso nonattainment area has unique considerations for CO attainment planning due to airshed contributions from Ciudad Juarez, Mexico. Section 179B of the 1990 CAA Amendments contains provisions for CO nonattainment areas affected by emissions emanating from outside the United States. Under CAA Section 179B, the EPA shall approve a SIP for VerDate Aug<31>2005 19:14 Jan 22, 2007 Jkt 211001 the El Paso nonattainment area if the TCEQ establishes to the EPA’s satisfaction that implementation of the plan would achieve timely attainment of the NAAQS but for emissions emanating from Ciudad Juarez. This provision prevents El Paso County from being reclassified to a higher level of nonattainment should monitors continue to record CO concentrations in excess of the NAAQS. To meet the CAA attainment schedule of December 31, 1995, Texas submitted an initial revision to the SIP for the El Paso CO moderate nonattainment area in a letter dated September 27, 1995. This submittal, as well as a February 1998 supplemental submittal, included air quality modeling demonstrating that El Paso would attain the CO NAAQS by December 31, 1995, but for emissions emanating outside of the United States from Mexico. The EPA approved a revision to the Texas SIP submitted to show attainment of the 8-hour CO NAAQS in the El Paso CO nonattainment area under Section 179B provisions, as well as approving the El Paso area’s CO emissions budget and a CO contingency measure requirement. The State submitted the revisions to satisfy Section 179B and Part D requirements of the CAA. This approval was published July 2, 2003 (68 FR 39457) and became effective September 2, 2003. TCEQ also submitted all the requirements for the moderate area classification and EPA approved them. See further discussion in Section II.B.2. On January 20, 2006, the State of Texas submitted a revision to the SIP which consists of a request for redesignation of the El Paso carbon monoxide (CO) nonattainment area to attainment for the CO NAAQS, as well as an 8-hour CO maintenance plan to ensure that El Paso County remains in attainment of the 8-hour CO NAAQS. In this action, we are approving a change in the legal designation of the El Paso area from nonattainment for CO to attainment, in addition to approving the maintenance plan that is designed to keep the area in attainment for CO until 2015. Under the CAA, we can change designations if acceptable data are available and if certain other requirements are met. Section 107(d)(3)(E) of the CAA provides that the Administrator may not promulgate a redesignation of a nonattainment area to attainment unless: (i) The Administrator determines that the area has attained the national ambient air quality standard; (ii) The Administrator has fully approved the applicable implementation plan for the area under CAA section 110(k); PO 00000 Frm 00011 Fmt 4700 Sfmt 4700 2777 (iii) The Administrator determines that the improvement in air quality is due to permanent and enforceable reductions in emissions resulting from implementation of the applicable implementation plan and applicable Federal air pollutant control regulations and other permanent and enforceable reductions; (iv) The Administrator has fully approved a maintenance plan for the area as meeting the requirements of CAA section 175A; and, (v) the State containing such area has met all requirements applicable to the area under section 110 and part D of the CAA. Before we can approve the redesignation request, we must decide that all applicable SIP elements have been fully approved. Approval of the applicable SIP elements may occur simultaneously with final approval of the redesignation request. The State of Texas has incorporated a CO maintenance plan into this submittal to satisfy the requirement of a fully approved maintenance plan for the area. II. EPA’s Evaluation of the El Paso Redesignation Request and Maintenance Plan We have reviewed the El Paso CO redesignation request and maintenance plan and believe that approval of the request is warranted, consistent with the requirements of CAA section 107(d)(3)(E). The following are descriptions of how the section 107(d)(3)(E) requirements are being addressed. (a) Redesignation Criterion: The Area Must Have Attained the Carbon Monoxide (CO) NAAQS Section 107(d)(3)(E)(i) of the CAA states that for an area to be redesignated to attainment, the Administrator must determine that the area has attained the applicable NAAQS. The area is designated attainment for the 1-hour CO NAAQS and designated nonattainment for the 8-hour CO NAAQS. As described in 40 CFR 50.8, the 8-hour CO NAAQS for carbon monoxide is 9 parts per million (ppm), (10 milligrams per cubic meter) for an 8-hour average concentration not to be exceeded more than once per year. 40 CFR 50.8 continues by stating that the levels of CO in the ambient air shall be measured by a reference method based on 40 CFR part 50, Appendix C and designated in accordance with 40 CFR part 53 or an equivalent method designated in accordance with 40 CFR part 53. Attainment of the 8-hour CO standard is not a momentary phenomenon based on short-term data. Instead, we consider an E:\FR\FM\23JAR1.SGM 23JAR1 2778 Federal Register / Vol. 72, No. 14 / Tuesday, January 23, 2007 / Rules and Regulations area to be in attainment if each of the 8-hour CO ambient air quality monitors in the area doesn’t have more than one exceedance of the 8-hour CO standard over a one-year period. If any monitor in the area’s CO monitoring network records more than one exceedance of the 8-hour CO standard during a oneyear calendar period, then the area is in violation of the 8-hour CO NAAQS. In addition, our interpretation of the CAA and EPA national policy 1 has been that an area seeking redesignation to attainment must show attainment of the CO NAAQS for at least a continuous two-year calendar period. In addition, the area must also continue to show attainment through the date that we promulgate the redesignation in the Federal Register. The State of Texas’ CO redesignation request for the El Paso area is based on an analysis of quality assured ambient air quality monitoring data that are relevant to the redesignation request. As presented in Chapter 3, Table 3–1 of the State’s maintenance plan, ambient air quality monitoring data for consecutive calendar years 1999 through 2005 show a measured exceedance rate of the CO NAAQS of 1.0 or less per year, per monitor, in the El Paso nonattainment area. We have evaluated the ambient air quality data and have determined that the El Paso area has not violated the 8hour CO standard and continues to demonstrate attainment. The El Paso nonattainment area has quality-assured data showing no violations of the 8-hour CO NAAQS for the most recent consecutive two-calendar-year period (2004 and 2005). Therefore, we believe the El Paso area has met the first component for redesignation: Demonstration of attainment of the CO NAAQS. We note too that the State of Texas has also committed, in the maintenance plan, to continue the necessary operation of the CO monitoring network in compliance with 40 CFR Part 58. jlentini on PROD1PC65 with RULES (b) Redesignation Criterion: The Area Must Have Met All Applicable Requirements Under Section 110 and Part D of the CAA To be redesignated to attainment, section 107(d)(3)(E)(v) requires that an area must meet all applicable requirements under section 110 and part D of the CAA. We interpret section 107(d)(3)(E)(v) to mean that for a redesignation to be approved by us, the State must meet all requirements that 1 Refer to EPA’s September 4, 1992, John Calcagni policy memorandum entitled ‘‘Procedures for Processing requests to Redesignate areas to Attainment.’’ VerDate Aug<31>2005 19:14 Jan 22, 2007 Jkt 211001 applied to the subject area prior to or at the time of the submission of a complete redesignation request. In our evaluation of a redesignation request, we don’t need to consider other requirements of the CAA that became due after the date of the submission of a complete redesignation request. 1. CAA Section 110 Requirements Section 110(a)(2) of Title I of the CAA delineates the general requirements for a SIP, which include enforceable emissions limitations and other control measures, means, or techniques, provisions for the establishment and operation of appropriate devices necessary to collect data on ambient air quality, and programs to enforce the limitations. On July 2, 2003, we approved the El Paso CO element revisions to Texas’s SIP as meeting the requirements of section 110(a)(2) of the CAA (see 68 FR 39457). 2. Part D Requirements Before the El Paso ‘‘moderate’’ CO nonattainment area may be redesignated to attainment, the State must have fulfilled the applicable requirements of part D. Under part D, an area’s classification indicates the requirements to which it will be subject. Subpart 1 of part D sets forth the basic nonattainment requirements applicable to all nonattainment areas. Subpart 3 of Part D contains specific provisions for ‘‘moderate’’ CO nonattainment areas. The relevant subpart 1 requirements are contained in sections 172(c) and 176. Our General Preamble (see 57 FR 13529 to 13532, April 16, 1992) provides EPA’s interpretations of the CAA requirements for ‘‘moderate’’ CO areas such as El Paso with CO design values that are less than or equal to 12.7 ppm. The General Preamble (see 57 FR 13530, et seq.) provides that the applicable requirements of CAA section 172 are: 172(c)(3) (emissions inventory), 172(c)(5) (new source review permitting program), 172(c)(7) (the section 110(a)(2) air quality monitoring requirements), and 172(c)(9) (contingency measures). Regarding the requirements of sections 172(c)(3) (inventory) and 172(c)(9) (contingency measures), please refer to our discussion below of sections 187(a)(1) and 187(a)(3), which are the more specific provisions of subpart 3 of Part D of the CAA. It is also worth noting that we interpreted the requirements of sections 172(c)(2) (reasonable further progress— RFP) and 172(c)(6) (other measures) as being irrelevant to a redesignation request because they only have meaning for an area that is not attaining the PO 00000 Frm 00012 Fmt 4700 Sfmt 4700 standard. See EPA’s September 4, 1992, John Calcagni memorandum entitled ‘‘Procedures for Processing Requests to Redesignate Areas to Attainment’’, and the General Preamble, 57 FR at 13564, dated April 16, 1992. Finally, the State has not sought to exercise the options that would trigger sections 172(c)(4) (identification of certain emissions increases) and 172(c)(8) (equivalent techniques). Thus, these provisions are also not relevant to this redesignation request. For the section 172(c)(5) New Source Review (NSR) requirements, the CAA requires all nonattainment areas to meet several requirements regarding NSR, including provisions to ensure that increased emissions will not result from any new or modified stationary major sources and a general offset rule. The State of Texas has an approved NSR program (see 60 FR 49781, September 27, 1995) that meets the requirements of CAA section 172(c)(5). For the CAA section 172(c)(7) provisions (compliance with the CAA section 110(a)(2) Air Quality Monitoring Requirements), our interpretations are presented in the General Preamble (57 FR 13535). CO nonattainment areas are to meet the ‘‘applicable’’ air quality monitoring requirements of section 110(a)(2) of the CAA. Information concerning CO monitoring in Texas is included in the Annual Monitoring Network Review (MNR) prepared by the State and submitted to EPA. Our personnel have concurred with Texas’ annual network reviews and have agreed that the El Paso network remains adequate. In Chapter 5, Section 5.4 of the maintenance plan, the State commits to the continued operation of the existing CO monitoring network according to applicable Federal regulations and guidelines (40 CFR part 58). The relevant subpart 3 provisions were created when the CAA was amended on November 15, 1990. The new CAA requirements for ‘‘moderate’’ CO areas, such as El Paso, required that the SIP be revised to include a 1990 base year emissions inventory (CAA section 187(a)(1)), contingency provisions (CAA section 187(a)(3)), corrections to existing motor vehicle inspection and maintenance (I/M) programs (CAA section 187(a)(4)), periodic emission inventories (CAA section 187(a)(5)), and the implementation of an oxygenated fuels program (CAA section 211(m)(1)). Sections 187(a)(2), (6), and (7) do not apply to the El Paso area because its design value was below 12.7 ppm at the time of classification. How the State met these requirements and our approvals, are described below: E:\FR\FM\23JAR1.SGM 23JAR1 Federal Register / Vol. 72, No. 14 / Tuesday, January 23, 2007 / Rules and Regulations A. 1990 base year emissions inventory (CAA section 187(a)(1)): EPA approved an emissions inventory on September 12, 1994 (see 59 FR 46766). B. Contingency provisions (CAA section 187(a)(3)): EPA approved the use of 46 tons per day in incremental CO reduction credits from the Texas lowenhanced vehicle inspection and maintenance program, as fulfillment of the State’s CO attainment contingency measure requirement for the El Paso nonattainment area under section 172(c)(9) on July 2, 2003 (see 68 FR 39457). C. Corrections to the El Paso basic I/M program (CAA section 187(a)(4)): EPA approved the Texas Motorist Choice (TMC) I/M Program (which includes El Paso) on November 14, 2001 (see 66 FR 57261). D. Periodic emissions inventories (CAA section 187(a)(5)): The State submitted an initial revision to the SIP for the El Paso CO moderate nonattainment area in a letter dated September 27, 1995. This submittal, as well as a February 1998 supplemental submittal contained a commitment to submit emission inventory updates. TCEQ continues to submit the Periodic Emissions Inventory (PEI) every three years. E. Oxygenated fuels program implementation (CAA section 211(m)): EPA approved the El Paso oxygenated fuels program on September 12, 1994 (see 59 FR 46766). jlentini on PROD1PC65 with RULES (c) Redesignation Criterion: The Area Must Have a Fully Approved SIP Under Section 110(k) of the CAA Section 107(d)(3)(E)(ii) of the CAA states that for an area to be redesignated to attainment, it must be determined that the Administrator has fully approved the applicable implementation plan for the area under section 110(k). As noted above, EPA previously approved SIP revisions for the El Paso CO nonattainment area that were required by the 1990 amendments to the CAA. In this action, we are also approving the maintenance plan proposed by the State, and the State’s commitment to maintain an adequate monitoring network (contained in the maintenance plan). Thus, with this final rule to approve the El Paso redesignation request and maintenance plan, we will have fully approved the El Paso CO element of the SIP under section 110(k) of the CAA. VerDate Aug<31>2005 19:14 Jan 22, 2007 Jkt 211001 (d) Redesignation Criterion: The Area Must Show That the Improvement in Air Quality Is Due to Permanent and Enforceable Emissions Reductions Section 107(d)(3)(E)(iii) of the CAA provides that for an area to be redesignated to attainment, the Administrator must determine that the improvement in air quality is due to permanent and enforceable reductions in emissions resulting from implementation of the applicable implementation plan, implementation of applicable Federal air pollutant control regulations, and other permanent and enforceable reductions. The CO emissions reductions for El Paso, that are further described in Sections 3.5 and 5.3.3 of the El Paso maintenance plan, were achieved primarily through the Federal Motor Vehicle Control Program (FMVCP), an oxygenated fuels program, and a motor vehicle inspection and maintenance (I/M) program. In general, the FMVCP provisions require vehicle manufacturers to meet more stringent vehicle emission limitations for new vehicles in future years. These emission limitations are phased in (as a percentage of new vehicles manufactured) over a period of years. As new, lower emitting vehicles replace older, higher emitting vehicles (‘‘fleet turnover’’), emission reductions are realized for a particular area such as El Paso. For example, EPA promulgated lower hydrocarbon (HC) and CO exhaust emission standards in 1991, known as Tier I standards for new motor vehicles (light-duty vehicles and light-duty trucks) in response to the 1990 CAA amendments. These Tier I emissions standards were phased in with 40% of the 1994 model year fleet, 80% of the 1995 model year fleet, and 100% of the 1996 model year fleet. As stated in Section 5.3.3 of the maintenance plan, significant additional emission reductions were realized from El Paso’s basic I/M program. The program requires annual inspections of vehicles at independent inspection stations. We note that further improvements to the El Paso area’s basic I/M program, to meet the requirements of EPA’s November 5, 1992 (57 FR 52950) I/M rule, and upgrading the I/M program to meet the requirements for a low-enhanced program, were approved by us into the SIP on November 14, 2001 (68 FR 39457). Oxygenated fuels are gasolines that are blended with additives that increase the level of oxygen in the fuel and, consequently, reduce CO tailpipe emissions. TAC Title 30, Chapter 114, Section 114.100, ‘‘Oxygenated Fuels PO 00000 Frm 00013 Fmt 4700 Sfmt 4700 2779 Program’’, contains the oxygenated fuels provisions for the El Paso nonattainment area. This rule requires all El Paso area gas stations to sell fuels containing a 2.7% minimum oxygen content (by weight) during the wintertime CO high pollution season. The use of oxygenated fuels has significantly reduced CO emissions and contributed to the area’s attainment of the CO NAAQS. We have evaluated the various State and Federal control measures, and believe that the improvement in air quality in the El Paso nonattainment area has resulted from emission reductions that are permanent and enforceable. (e) Redesignation Criterion: The Area Must Have a Fully Approved Maintenance Plan Under CAA Section 175A Section 107(d)(3)(E)(iv) of the CAA provides that for an area to be redesignated to attainment, the Administrator must have fully approved a maintenance plan for the area meeting the requirements of section 175A of the CAA. Section 175A of the CAA sets forth the elements of a maintenance plan for areas seeking redesignation from nonattainment to attainment. The maintenance plan must demonstrate continued attainment of the applicable NAAQS for at least ten years after the Administrator approves a redesignation to attainment. Eight years after the promulgation of the redesignation, the State must submit a revised maintenance plan that demonstrates continued attainment for the subsequent ten-year period following the initial ten year maintenance period. To address the possibility of future NAAQS violations, the maintenance plan must contain contingency measures, with a schedule for adoption and implementation, that are adequate to assure prompt correction of a violation. In addition, we issued further maintenance plan interpretations in the ‘‘General Preamble for the Implementation of Title I of the Clean Air Act Amendments of 1990’’ (57 FR 13498, April 16, 1992), ‘‘General Preamble for the Implementation of Title I of the Clean Air Act Amendments of 1990; Supplemental’’ (57 FR 18070, April 28, 1992), and the EPA guidance memorandum entitled ‘‘Procedures for Processing Requests to Redesignate Areas to Attainment’’ from John Calcagni, Director, Air Quality Management Division, Office of Air Quality and Planning Standards, to Regional Air Division Directors, dated September 4, 1992 (hereafter the September 4, 1992 Calcagni Memorandum). E:\FR\FM\23JAR1.SGM 23JAR1 2780 Federal Register / Vol. 72, No. 14 / Tuesday, January 23, 2007 / Rules and Regulations In this Federal Register action, EPA is approving the maintenance plan for the El Paso CO nonattainment area because we believe, as detailed below, that the State’s maintenance plan submittal meets the requirements of section 175A and is consistent with our interpretations of the CAA, as reflected in the documents referenced above. Our analysis of the pertinent maintenance plan requirements, with reference to the State’s January 20, 2006, submittal, is provided as follows: 1. Emissions Inventories—Attainment Year and Projections EPA’s interpretations of the CAA section 175A maintenance plan requirements are generally provided in the General Preamble (see 57 FR 13498, April 16, 1992) and the September 4, 1992, Calcagni Memorandum referenced above. Under our interpretations, areas seeking to redesignate to attainment for CO may demonstrate future maintenance of the CO NAAQS either by showing that future CO emissions will be equal to or less than the attainment year emissions or by providing a modeling demonstration. For the El Paso area, the State selected the emissions inventory approach for demonstrating maintenance of the CO NAAQS; however, the State also conducted ‘‘hot spot’’ CO modeling to demonstrate that CO exceedances are not currently occurring at a potential hot spot and will not occur at such locations in the future. The maintenance plan submitted by the TCEQ on January 20, 2006, includes comprehensive inventories of CO emissions for the El Paso area. These inventories include emissions from stationary point sources, area sources, non-road mobile sources, and on-road mobile sources. The State selected 2002 as the year from which to develop the attainment year inventory and included interim-year projections out to 2015. More detailed descriptions of the 2002 attainment year inventory and the projected inventories are documented in the maintenance plan in Chapter 2. Summary emission figures from the 2002 attainment year, the interim projected years, and the final maintenance year of 2015 are provided in Table 1 below.

Onroad Mobile ................................................................................................. 427.33 385.43 322.78 314.40 As presented in Chapter 3, Table 3– 1 of the State’s maintenance plan, ambient air quality monitoring data for consecutive calendar years 1999 through 2004 show a measured exceedance rate of the CO NAAQS of 1.0 or less per year, per monitor, in the El Paso nonattainment area. To further demonstrate maintenance of the CO NAAQS, the TCEQ agreed to additional ‘‘hot spot’’ modeling as requested by EPA on the basis of EPA’s Office of Air Quality Planning and Standards’ (OAQPS) September 30, 1994 Ozone/ Carbon Monoxide Redesignations Reference Document. The modeling was done specifically to address two concerns—the El Paso CO monitoring network has a limited number of sites, and therefore may not have identified all the hot spots in the El Paso area; and in the future, urban growth may increase mobile emissions enough to cause exceedances of the NAAQS. The TCEQ performed CO modeling at a heavily utilized intersection to demonstrate that CO exceedances are not currently occurring at a potential hot spot and will not occur at that location in the future. A modeling protocol detailing hotspot selection, proposed model usage, and data analysis was submitted by the State on February 17, 2005, and was approved by EPA via a letter dated March 30, 2005. The modeling protocol and approach VerDate Aug<31>2005 19:14 Jan 22, 2007 Jkt 211001 taken are detailed in Chapter 4 of the maintenance plan. As shown in Table 4–2 of the maintenance plan, the current (base) case hot spot analysis predicted a maximum 8-hour CO concentration of 7.8 ppm, and the 2015 future case analysis predicted a maximum 8-hour CO concentration of 2.2 ppm. Both of these values are below the 9 ppm NAAQS, and demonstrate current and projected compliance with the CO standard. A more detailed evaluation by EPA of this hot spot analysis is provided in the TSD. 2. Demonstration of Maintenance— Projected Inventories As we noted above, total CO emissions were projected forward by the State for the years 2005, 2011, and 2015. We note the State’s approach for developing the projected inventories follows EPA guidance on projected emissions and we believe they are acceptable.2 The projected inventories show that CO emissions are not estimated to exceed the 2002 attainment level during the time period 2002 through 2015 and, therefore, the El Paso area has satisfactorily demonstrated maintenance. The year 2005 was 2 ‘‘Use of Actual Emissions in Maintenance Demonstrations for Ozone and Carbon Monoxide (CO) Nonattainment Areas’’, signed by D. Kent Berry, Acting Director, Air Quality Management Division, November 30, 1993. PO 00000 Frm 00014 Fmt 4700 Sfmt 4700 selected as the year of designation of attainment for the 8-hour CO NAAQS, so the final projection year, 2015, was intended to represent the last year of the 10-year maintenance plan. The year 2011 was selected as an interim year for conformity determination. These projected inventories were developed using EPA-approved technologies and methodologies. No new control strategies for point and area sources were relied upon in the projected inventories. CO emission reductions anticipated from EPA’s national rule for the Spark Ignition Small Engine Rule, Phase 1, were relied upon as a new control strategy for Nonroad sources. TCEQ relied upon emissions reductions anticipated from existing control strategies: FMVCP, Texas Oxygenated Fuel SIP, and the Texas I/M Program. Please see the TSD for more information on EPA’s review and evaluation of the State’s methodologies, modeling, inputs, etc., for developing the projected emissions inventories. 3. Monitoring Network and Verification of Continued Attainment The TCEQ commits to maintain an appropriate air monitoring network for the El Paso area throughout the 10-year maintenance period. As required by 40 CFR Part 58.20(d), TCEQ will consult with EPA in annual review of the air monitoring network to determine the E:\FR\FM\23JAR1.SGM 23JAR1 Federal Register / Vol. 72, No. 14 / Tuesday, January 23, 2007 / Rules and Regulations jlentini on PROD1PC65 with RULES adequacy of the CO monitoring network, whether or not additional monitoring is needed, and if/when monitor sites can be discontinued. The TCEQ also commits to adhere to data quality requirements as specified in 40 CFR Part 58 Quality Assurance Requirements. Texas commits to track the progress of the maintenance plan by continuing to periodically update the emissions inventory (EI). It will compare the updated EIs against the projected 2005, 2011 and 2015 EIs. TCEQ also commits to continuing all the applicable control strategies, i.e., the measures approved into the El Paso SIP. For example, these measures include the Federal Motor Vehicle Control Program (FMVCP), an oxygenated fuels program, and a motor vehicle inspection and maintenance (I/M) program. Based on the above, we are approving these commitments as satisfying the relevant requirements and we note that his final rulemaking approval will render the State’s commitments federally enforceable. 4. Contingency Plan Section 175A(d) of the CAA requires that a maintenance plan include contingency provisions. To meet this requirement, the State has identified appropriate contingency measures along with a schedule for the development and implementation of such measures. In the January 20, 2006 submittal, Texas specifies the contingency trigger as a violation of the 8-hour CO standard base upon air quality monitoring data from the El Paso monitoring network. In the event that a monitored violation of the 8-hour CO standard occurs in any portion of the maintenance area, the State will first analyze the data to determine if the violation was caused by actions outside TCEQ’s jurisdiction (e.g., emissions from Mexico or another state) or within its jurisdiction. If the violation was caused by actions outside TCEQ’s jurisdiction, TCEQ will notify the EPA. If TCEQ determines the violation was caused by actions within TCEQ’s jurisdiction, TCEQ commits to adopt and implement the identified contingency measures as expeditiously as practicable, but no later than 18 months. The State will analyze one or more of the following contingency measures to reattain the standard: • Vehicle idling restrictions. • Improved vehicle I/M. • Improved traffic control measures. The maintenance plan indicates that the State may evaluate other potential strategies to address any future violations in the most appropriate and effective manner possible. Based on the VerDate Aug<31>2005 19:14 Jan 22, 2007 Jkt 211001 above, we find that the contingency measures provided in the State’s El Paso CO maintenance plan are sufficient and meet the requirements of section 175A(d) of the CAA. 5. Subsequent Maintenance Plan Revisions In accordance with section 175A(b) of the CAA, Texas has committed to submit a revised maintenance plan eight years after our approval of the redesignation. This provision for revising the maintenance plan is contained in Chapter 5, Section 5.1 of the El Paso CO maintenance plan. The maintenance plan adequately addresses the five basic components of a maintenance plan. EPA believes that the 8-hour CO maintenance plan SIP revision submitted by the State of Texas for the El Paso area meets the requirements of Section 175A of the CAA. For more information, please refer to our Technical Support Document. III. EPA’s Evaluation of the Transportation Conformity Requirements Table 2 documents the motor vehicle emissions budgets (MVEBs) for the El Paso CO nonattainment area that have been established by this CO redesignation request. The MVEB is that portion of the total allowable emissions defined in the SIP revision allocated to on-road mobile sources for a certain date for meeting the purpose of the SIP, in this case maintaining compliance with the NAAQS in the nonattainment or maintenance area. EPA’s conformity rule (40 CFR part 51, subpart T and part 93, subpart A) requires that transportation plans, programs and projects in nonattainment or maintenance areas conform to the SIP. The motor vehicle emissions budget is one mechanism EPA has identified for demonstrating conformity. Upon the effective date of this SIP approval, all future transportation improvement programs and long range transportation plans for the El Paso area will have to show conformity to the budgets in this plan; previous budgets approved or found adequate will no longer be applicable. TABLE 2.—EL PASO CO MVEB FOR 2002–2015 (TPD) Year MVEB 2002 .................................................. 2011 .................................................. 2015 .................................................. 29.66 18.56 16.63 Our analysis indicates that the above figures are consistent with maintenance PO 00000 Frm 00015 Fmt 4700 Sfmt 4700 2781 of the CO NAAQS throughout the maintenance period. In accordance with EPA’s adequacy process, these MVEBs were posted on EPA’s adequacy Web site for public notice on May 4, 2006 and were open for comment until June 5, 2006. No comments were received during this period. Therefore, we are finding as adequate and approving the 29.66 tpd for 2002 through 2010, 18.56 tpd for 2011 through 2014, and 16.63 tpd for 2015 and beyond, CO emissions budgets for the El Paso area. Budget modeling was developed for TCEQ under contract by the Texas Transportation Institute (TTI), utilizing El Paso travel model datasets developed by the El Paso Metropolitan Planning Organization. The modeling incorporated two onroad source control strategies that apply in the El Paso area: The El Paso Oxygenated Fuel Program, and the I/M program (both detailed in Chapter 5, Section 5.3.3 of the maintenance plan). IV. Consideration of Section 110(l) of the CAA Section 110(l) of the CAA states that a SIP revision cannot be approved if the revision would interfere with any applicable requirement concerning attainment and reasonable further progress towards attainment of a NAAQS or any other applicable requirement of the CAA. As stated above, the El Paso area has shown continuous attainment of the CO NAAQS since 1999 and has met the applicable Federal requirements for redesignation to attainment. The maintenance plan will not interfere with attainment or any other applicable requirement of the CAA. No control measures in the El Paso SIP are being removed. V. Final Action EPA is approving the redesignation of the El Paso area to attainment of the 8hour CO NAAQS, as well as approving the El Paso area CO maintenance plan. We also are approving the associated MVEBs. We have evaluated the State’s submittal and have determined that it meets the applicable requirements of the Clean Air Act and EPA regulations, and is consistent with EPA policy. EPA is publishing this rule without prior proposal because we view this as a non-controversial amendment and anticipate no adverse comments. However, in the ‘‘Proposed Rules’’ section of today’s Federal Register, we are publishing a separate document that will serve as the proposed rule to approve the SIP revision if relevant adverse comments are received on this E:\FR\FM\23JAR1.SGM 23JAR1 2782 Federal Register / Vol. 72, No. 14 / Tuesday, January 23, 2007 / Rules and Regulations direct final rule. We will not institute a second comment period on this action. Any parties interested in commenting must do so at this time. For further information about commenting on this rule, see the ADDRESSES section of this document. If EPA receives adverse comment, we will publish a timely withdrawal in the Federal Register informing the public that the rule will not take effect. We would address all public comments in a subsequent final rule based on the proposed rule. Please note that if we receive adverse comment on an amendment, paragraph, or section of this rule and if that provision may be severed from the remainder of the rule, we may adopt as final those provisions of the rule that are not the subject of an adverse comment. VI. Statutory and Executive Order Reviews jlentini on PROD1PC65 with RULES Under Executive Order 12866 (58 FR 51735, October 4, 1993), this action is not a ‘‘significant regulatory action’’ and therefore is not subject to review by the Office of Management and Budget. For this reason, this action is also not subject to Executive Order 13211, ‘‘Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use’’ (66 FR 28355, May 22, 2001). This action merely approves state law as meeting Federal requirements and imposes no additional requirements beyond those imposed by state law. Accordingly, the Administrator certifies that this rule will not have a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.). Because this rule approves pre-existing requirements under state law and does not impose any additional enforceable duty beyond that required by state law, it 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). This rule also does not have tribal implications because it will not have a substantial direct effect on one or more Indian tribes, on the relationship between the Federal Government and Indian tribes, or on the distribution of VerDate Aug<31>2005 19:14 Jan 22, 2007 Jkt 211001 power and responsibilities between the Federal Government and Indian tribes, as specified by Executive Order 13175 (65 FR 67249, November 9, 2000). This action also does not have federalism implications because it does not have substantial direct effects on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government, as specified in Executive Order 13132 (64 FR 43255, August 10, 1999). This action merely approves a state rule implementing a Federal standard, and does not alter the relationship or the distribution of power and responsibilities established in the CAA. This rule also is not subject to Executive Order 13045 ‘‘Protection of Children from Environmental Health Risks and Safety Risks’’ (62 FR 19885, April 23, 1997), because it is not economically significant. In reviewing SIP submissions, EPA’s role is to approve state choices, provided that they meet the criteria of the Clean Air Act. In this context, in the absence of a prior existing requirement for the State to use voluntary consensus standards (VCS), EPA has no authority to disapprove a SIP submission for failure to use VCS. It would thus be inconsistent with applicable law for EPA, when it reviews a SIP submission, to use VCS in place of a SIP submission that otherwise satisfies the provisions of the CAA. Thus, the requirements of section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) do not apply. This rule does not impose an information collection burden under the provisions of the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.). 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 rule and other required information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the United PO 00000 Frm 00016 Fmt 4700 Sfmt 4700 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 CAA, petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by March 26, 2007. Filing a petition for reconsideration by the Administrator of this final rule does not affect the finality of this rule 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).)

Approval and Promulgation of Implementation Plans; Texas; El Paso
County Carbon Monoxide Redesignation to Attainment, and Approval of
Maintenance Plan

AGENCY: Environmental Protection Agency (EPA).

ACTION: Direct final rule.

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

SUMMARY: On January 20, 2006, the Texas Commission on Environmental
Quality (TCEQ) submitted a State Implementation Plan (SIP) revision to
request redesignation of the El Paso carbon monoxide (CO) nonattainment
area to attainment for the CO National Ambient Air Quality Standard
(NAAQS). This submittal also included a CO maintenance plan for the El
Paso area and associated Motor Vehicle Emission Budgets (MVEBs). The
maintenance plan was developed to ensure continued attainment of the CO
NAAQS for a period of 10 years from the effective date of EPA approval
of redesignation to attainment. In this action, EPA is approving the El
Paso CO redesignation request and the maintenance plan with its
associated MVEBs as satisfying the requirements of the Federal Clean
Air Act (CAA) as amended in 1990.

DATES: This rule is effective on March 26, 2007 without further notice,
unless EPA receives relevant adverse comment by February 22, 2007.

I. Background

Under the 1990 Federal Clean Air Act (CAA) Amendments, El Paso was
designated and classified as a moderate nonattainment area for CO
because it did not meet the 8-hour CO NAAQS for this criteria pollutant
(56 FR 56694). El Paso's classification as a moderate nonattainment
area under sections 107(d)(4)(A) and 186(a) of the CAA imposed a
schedule for attainment of the CO NAAQS by December 31, 1995.
The El Paso nonattainment area has unique considerations for CO
attainment planning due to airshed contributions from Ciudad Juarez,
Mexico. Section 179B of the 1990 CAA Amendments contains provisions for
CO nonattainment areas affected by emissions emanating from outside the
United States. Under CAA Section 179B, the EPA shall approve a SIP for
the El Paso nonattainment area if the TCEQ establishes to the EPA's
satisfaction that implementation of the plan would achieve timely
attainment of the NAAQS but for emissions emanating from Ciudad Juarez.
This provision prevents El Paso County from being reclassified to a
higher level of nonattainment should monitors continue to record CO
concentrations in excess of the NAAQS.
To meet the CAA attainment schedule of December 31, 1995, Texas
submitted an initial revision to the SIP for the El Paso CO moderate
nonattainment area in a letter dated September 27, 1995. This
submittal, as well as a February 1998 supplemental submittal, included
air quality modeling demonstrating that El Paso would attain the CO
NAAQS by December 31, 1995, but for emissions emanating outside of the
United States from Mexico. The EPA approved a revision to the Texas SIP
submitted to show attainment of the 8-hour CO NAAQS in the El Paso CO
nonattainment area under Section 179B provisions, as well as approving
the El Paso area's CO emissions budget and a CO contingency measure
requirement. The State submitted the revisions to satisfy Section 179B
and Part D requirements of the CAA. This approval was published July 2,
2003 (68 FR 39457) and became effective September 2, 2003. TCEQ also
submitted all the requirements for the moderate area classification and
EPA approved them. See further discussion in Section II.B.2.
On January 20, 2006, the State of Texas submitted a revision to the
SIP which consists of a request for redesignation of the El Paso carbon
monoxide (CO) nonattainment area to attainment for the CO NAAQS, as
well as an 8-hour CO maintenance plan to ensure that El Paso County
remains in attainment of the 8-hour CO NAAQS.
In this action, we are approving a change in the legal designation
of the El Paso area from nonattainment for CO to attainment, in
addition to approving the maintenance plan that is designed to keep the
area in attainment for CO until 2015. Under the CAA, we can change
designations if acceptable data are available and if certain other
requirements are met. Section 107(d)(3)(E) of the CAA provides that the
Administrator may not promulgate a redesignation of a nonattainment
area to attainment unless:
(i) The Administrator determines that the area has attained the
national ambient air quality standard;
(ii) The Administrator has fully approved the applicable
implementation plan for the area under CAA section 110(k);
(iii) The Administrator determines that the improvement in air
quality is due to permanent and enforceable reductions in emissions
resulting from implementation of the applicable implementation plan and
applicable Federal air pollutant control regulations and other
permanent and enforceable reductions;
(iv) The Administrator has fully approved a maintenance plan for
the area as meeting the requirements of CAA section 175A; and,
(v) the State containing such area has met all requirements
applicable to the area under section 110 and part D of the CAA.
Before we can approve the redesignation request, we must decide
that all applicable SIP elements have been fully approved. Approval of
the applicable SIP elements may occur simultaneously with final
approval of the redesignation request. The State of Texas has
incorporated a CO maintenance plan into this submittal to satisfy the
requirement of a fully approved maintenance plan for the area.

II. EPA's Evaluation of the El Paso Redesignation Request and
Maintenance Plan

We have reviewed the El Paso CO redesignation request and
maintenance plan and believe that approval of the request is warranted,
consistent with the requirements of CAA section 107(d)(3)(E). The
following are descriptions of how the section 107(d)(3)(E) requirements
are being addressed.

(a) Redesignation Criterion: The Area Must Have Attained the Carbon
Monoxide (CO) NAAQS

Section 107(d)(3)(E)(i) of the CAA states that for an area to be
redesignated to attainment, the Administrator must determine that the
area has attained the applicable NAAQS. The area is designated
attainment for the 1-hour CO NAAQS and designated nonattainment for the
8-hour CO NAAQS. As described in 40 CFR 50.8, the 8-hour CO NAAQS for
carbon monoxide is 9 parts per million (ppm), (10 milligrams per cubic
meter) for an 8-hour average concentration not to be exceeded more than
once per year. 40 CFR 50.8 continues by stating that the levels of CO
in the ambient air shall be measured by a reference method based on 40
CFR part 50, Appendix C and designated in accordance with 40 CFR part
53 or an equivalent method designated in accordance with 40 CFR part
53. Attainment of the 8-hour CO standard is not a momentary phenomenon
based on short-term data. Instead, we consider an

[[Page 2778]]

area to be in attainment if each of the 8-hour CO ambient air quality
monitors in the area doesn't have more than one exceedance of the 8-
hour CO standard over a one-year period. If any monitor in the area's
CO monitoring network records more than one exceedance of the 8-hour CO
standard during a one-year calendar period, then the area is in
violation of the 8-hour CO NAAQS. In addition, our interpretation of
the CAA and EPA national policy \1\ has been that an area seeking
redesignation to attainment must show attainment of the CO NAAQS for at
least a continuous two-year calendar period. In addition, the area must
also continue to show attainment through the date that we promulgate
the redesignation in the Federal Register.
---------------------------------------------------------------------------

\1\ Refer to EPA's September 4, 1992, John Calcagni policy
memorandum entitled ``Procedures for Processing requests to
Redesignate areas to Attainment.''
---------------------------------------------------------------------------

The State of Texas' CO redesignation request for the El Paso area
is based on an analysis of quality assured ambient air quality
monitoring data that are relevant to the redesignation request. As
presented in Chapter 3, Table 3-1 of the State's maintenance plan,
ambient air quality monitoring data for consecutive calendar years 1999
through 2005 show a measured exceedance rate of the CO NAAQS of 1.0 or
less per year, per monitor, in the El Paso nonattainment area. We have
evaluated the ambient air quality data and have determined that the El
Paso area has not violated the 8-hour CO standard and continues to
demonstrate attainment. The El Paso nonattainment area has quality-
assured data showing no violations of the 8-hour CO NAAQS for the most
recent consecutive two-calendar-year period (2004 and 2005). Therefore,
we believe the El Paso area has met the first component for
redesignation: Demonstration of attainment of the CO NAAQS. We note too
that the State of Texas has also committed, in the maintenance plan, to
continue the necessary operation of the CO monitoring network in
compliance with 40 CFR Part 58.

(b) Redesignation Criterion: The Area Must Have Met All Applicable
Requirements Under Section 110 and Part D of the CAA

To be redesignated to attainment, section 107(d)(3)(E)(v) requires
that an area must meet all applicable requirements under section 110
and part D of the CAA. We interpret section 107(d)(3)(E)(v) to mean
that for a redesignation to be approved by us, the State must meet all
requirements that applied to the subject area prior to or at the time
of the submission of a complete redesignation request. In our
evaluation of a redesignation request, we don't need to consider other
requirements of the CAA that became due after the date of the
submission of a complete redesignation request.
1. CAA Section 110 Requirements
Section 110(a)(2) of Title I of the CAA delineates the general
requirements for a SIP, which include enforceable emissions limitations
and other control measures, means, or techniques, provisions for the
establishment and operation of appropriate devices necessary to collect
data on ambient air quality, and programs to enforce the limitations.
On July 2, 2003, we approved the El Paso CO element revisions to
Texas's SIP as meeting the requirements of section 110(a)(2) of the CAA
(see 68 FR 39457).
2. Part D Requirements
Before the El Paso ``moderate'' CO nonattainment area may be
redesignated to attainment, the State must have fulfilled the
applicable requirements of part D. Under part D, an area's
classification indicates the requirements to which it will be subject.
Subpart 1 of part D sets forth the basic nonattainment requirements
applicable to all nonattainment areas. Subpart 3 of Part D contains
specific provisions for ``moderate'' CO nonattainment areas. The
relevant subpart 1 requirements are contained in sections 172(c) and
176. Our General Preamble (see 57 FR 13529 to 13532, April 16, 1992)
provides EPA's interpretations of the CAA requirements for ``moderate''
CO areas such as El Paso with CO design values that are less than or
equal to 12.7 ppm. The General Preamble (see 57 FR 13530, et seq.)
provides that the applicable requirements of CAA section 172 are:
172(c)(3) (emissions inventory), 172(c)(5) (new source review
permitting program), 172(c)(7) (the section 110(a)(2) air quality
monitoring requirements), and 172(c)(9) (contingency measures).
Regarding the requirements of sections 172(c)(3) (inventory) and
172(c)(9) (contingency measures), please refer to our discussion below
of sections 187(a)(1) and 187(a)(3), which are the more specific
provisions of subpart 3 of Part D of the CAA.
It is also worth noting that we interpreted the requirements of
sections 172(c)(2) (reasonable further progress--RFP) and 172(c)(6)
(other measures) as being irrelevant to a redesignation request because
they only have meaning for an area that is not attaining the standard.
See EPA's September 4, 1992, John Calcagni memorandum entitled
``Procedures for Processing Requests to Redesignate Areas to
Attainment'', and the General Preamble, 57 FR at 13564, dated April 16,
1992. Finally, the State has not sought to exercise the options that
would trigger sections 172(c)(4) (identification of certain emissions
increases) and 172(c)(8) (equivalent techniques). Thus, these
provisions are also not relevant to this redesignation request.
For the section 172(c)(5) New Source Review (NSR) requirements, the
CAA requires all nonattainment areas to meet several requirements
regarding NSR, including provisions to ensure that increased emissions
will not result from any new or modified stationary major sources and a
general offset rule. The State of Texas has an approved NSR program
(see 60 FR 49781, September 27, 1995) that meets the requirements of
CAA section 172(c)(5). For the CAA section 172(c)(7) provisions
(compliance with the CAA section 110(a)(2) Air Quality Monitoring
Requirements), our interpretations are presented in the General
Preamble (57 FR 13535). CO nonattainment areas are to meet the
``applicable'' air quality monitoring requirements of section 110(a)(2)
of the CAA. Information concerning CO monitoring in Texas is included
in the Annual Monitoring Network Review (MNR) prepared by the State and
submitted to EPA. Our personnel have concurred with Texas' annual
network reviews and have agreed that the El Paso network remains
adequate.
In Chapter 5, Section 5.4 of the maintenance plan, the State
commits to the continued operation of the existing CO monitoring
network according to applicable Federal regulations and guidelines (40
CFR part 58).
The relevant subpart 3 provisions were created when the CAA was
amended on November 15, 1990. The new CAA requirements for ``moderate''
CO areas, such as El Paso, required that the SIP be revised to include
a 1990 base year emissions inventory (CAA section 187(a)(1)),
contingency provisions (CAA section 187(a)(3)), corrections to existing
motor vehicle inspection and maintenance (I/M) programs (CAA section
187(a)(4)), periodic emission inventories (CAA section 187(a)(5)), and
the implementation of an oxygenated fuels program (CAA section
211(m)(1)). Sections 187(a)(2), (6), and (7) do not apply to the El
Paso area because its design value was below 12.7 ppm at the time of
classification. How the State met these requirements and our approvals,
are described below:

[[Page 2779]]

A. 1990 base year emissions inventory (CAA section 187(a)(1)): EPA
approved an emissions inventory on September 12, 1994 (see 59 FR
46766).
B. Contingency provisions (CAA section 187(a)(3)): EPA approved the
use of 46 tons per day in incremental CO reduction credits from the
Texas low-enhanced vehicle inspection and maintenance program, as
fulfillment of the State's CO attainment contingency measure
requirement for the El Paso nonattainment area under section 172(c)(9)
on July 2, 2003 (see 68 FR 39457).
C. Corrections to the El Paso basic I/M program (CAA section
187(a)(4)): EPA approved the Texas Motorist Choice (TMC) I/M Program
(which includes El Paso) on November 14, 2001 (see 66 FR 57261).
D. Periodic emissions inventories (CAA section 187(a)(5)): The
State submitted an initial revision to the SIP for the El Paso CO
moderate nonattainment area in a letter dated September 27, 1995. This
submittal, as well as a February 1998 supplemental submittal contained
a commitment to submit emission inventory updates. TCEQ continues to
submit the Periodic Emissions Inventory (PEI) every three years.
E. Oxygenated fuels program implementation (CAA section 211(m)):
EPA approved the El Paso oxygenated fuels program on September 12, 1994
(see 59 FR 46766).

Section 107(d)(3)(E)(ii) of the CAA states that for an area to be
redesignated to attainment, it must be determined that the
Administrator has fully approved the applicable implementation plan for
the area under section 110(k). As noted above, EPA previously approved
SIP revisions for the El Paso CO nonattainment area that were required
by the 1990 amendments to the CAA. In this action, we are also
approving the maintenance plan proposed by the State, and the State's
commitment to maintain an adequate monitoring network (contained in the
maintenance plan). Thus, with this final rule to approve the El Paso
redesignation request and maintenance plan, we will have fully approved
the El Paso CO element of the SIP under section 110(k) of the CAA.

(d) Redesignation Criterion: The Area Must Show That the Improvement in
Air Quality Is Due to Permanent and Enforceable Emissions Reductions

Section 107(d)(3)(E)(iii) of the CAA provides that for an area to
be redesignated to attainment, the Administrator must determine that
the improvement in air quality is due to permanent and enforceable
reductions in emissions resulting from implementation of the applicable
implementation plan, implementation of applicable Federal air pollutant
control regulations, and other permanent and enforceable reductions.
The CO emissions reductions for El Paso, that are further described in
Sections 3.5 and 5.3.3 of the El Paso maintenance plan, were achieved
primarily through the Federal Motor Vehicle Control Program (FMVCP), an
oxygenated fuels program, and a motor vehicle inspection and
maintenance (I/M) program.
In general, the FMVCP provisions require vehicle manufacturers to
meet more stringent vehicle emission limitations for new vehicles in
future years. These emission limitations are phased in (as a percentage
of new vehicles manufactured) over a period of years. As new, lower
emitting vehicles replace older, higher emitting vehicles (``fleet
turnover''), emission reductions are realized for a particular area
such as El Paso. For example, EPA promulgated lower hydrocarbon (HC)
and CO exhaust emission standards in 1991, known as Tier I standards
for new motor vehicles (light-duty vehicles and light-duty trucks) in
response to the 1990 CAA amendments. These Tier I emissions standards
were phased in with 40% of the 1994 model year fleet, 80% of the 1995
model year fleet, and 100% of the 1996 model year fleet.
As stated in Section 5.3.3 of the maintenance plan, significant
additional emission reductions were realized from El Paso's basic I/M
program. The program requires annual inspections of vehicles at
independent inspection stations. We note that further improvements to
the El Paso area's basic I/M program, to meet the requirements of EPA's
November 5, 1992 (57 FR 52950) I/M rule, and upgrading the I/M program
to meet the requirements for a low-enhanced program, were approved by
us into the SIP on November 14, 2001 (68 FR 39457).
Oxygenated fuels are gasolines that are blended with additives that
increase the level of oxygen in the fuel and, consequently, reduce CO
tailpipe emissions. TAC Title 30, Chapter 114, Section 114.100,
``Oxygenated Fuels Program'', contains the oxygenated fuels provisions
for the El Paso nonattainment area. This rule requires all El Paso area
gas stations to sell fuels containing a 2.7% minimum oxygen content (by
weight) during the wintertime CO high pollution season. The use of
oxygenated fuels has significantly reduced CO emissions and contributed
to the area's attainment of the CO NAAQS.
We have evaluated the various State and Federal control measures,
and believe that the improvement in air quality in the El Paso
nonattainment area has resulted from emission reductions that are
permanent and enforceable.

(e) Redesignation Criterion: The Area Must Have a Fully Approved
Maintenance Plan Under CAA Section 175A

Section 107(d)(3)(E)(iv) of the CAA provides that for an area to be
redesignated to attainment, the Administrator must have fully approved
a maintenance plan for the area meeting the requirements of section
175A of the CAA. Section 175A of the CAA sets forth the elements of a
maintenance plan for areas seeking redesignation from nonattainment to
attainment. The maintenance plan must demonstrate continued attainment
of the applicable NAAQS for at least ten years after the Administrator
approves a redesignation to attainment. Eight years after the
promulgation of the redesignation, the State must submit a revised
maintenance plan that demonstrates continued attainment for the
subsequent ten-year period following the initial ten year maintenance
period. To address the possibility of future NAAQS violations, the
maintenance plan must contain contingency measures, with a schedule for
adoption and implementation, that are adequate to assure prompt
correction of a violation. In addition, we issued further maintenance
plan interpretations in the ``General Preamble for the Implementation
of Title I of the Clean Air Act Amendments of 1990'' (57 FR 13498,
April 16, 1992), ``General Preamble for the Implementation of Title I
of the Clean Air Act Amendments of 1990; Supplemental'' (57 FR 18070,
April 28, 1992), and the EPA guidance memorandum entitled ``Procedures
for Processing Requests to Redesignate Areas to Attainment'' from John
Calcagni, Director, Air Quality Management Division, Office of Air
Quality and Planning Standards, to Regional Air Division Directors,
dated September 4, 1992 (hereafter the September 4, 1992 Calcagni
Memorandum).

[[Page 2780]]

In this Federal Register action, EPA is approving the maintenance
plan for the El Paso CO nonattainment area because we believe, as
detailed below, that the State's maintenance plan submittal meets the
requirements of section 175A and is consistent with our interpretations
of the CAA, as reflected in the documents referenced above. Our
analysis of the pertinent maintenance plan requirements, with reference
to the State's January 20, 2006, submittal, is provided as follows:
1. Emissions Inventories--Attainment Year and Projections
EPA's interpretations of the CAA section 175A maintenance plan
requirements are generally provided in the General Preamble (see 57 FR
13498, April 16, 1992) and the September 4, 1992, Calcagni Memorandum
referenced above. Under our interpretations, areas seeking to
redesignate to attainment for CO may demonstrate future maintenance of
the CO NAAQS either by showing that future CO emissions will be equal
to or less than the attainment year emissions or by providing a
modeling demonstration.
For the El Paso area, the State selected the emissions inventory
approach for demonstrating maintenance of the CO NAAQS; however, the
State also conducted ``hot spot'' CO modeling to demonstrate that CO
exceedances are not currently occurring at a potential hot spot and
will not occur at such locations in the future. The maintenance plan
submitted by the TCEQ on January 20, 2006, includes comprehensive
inventories of CO emissions for the El Paso area. These inventories
include emissions from stationary point sources, area sources, non-road
mobile sources, and on-road mobile sources. The State selected 2002 as
the year from which to develop the attainment year inventory and
included interim-year projections out to 2015. More detailed
descriptions of the 2002 attainment year inventory and the projected
inventories are documented in the maintenance plan in Chapter 2.
Summary emission figures from the 2002 attainment year, the interim
projected years, and the final maintenance year of 2015 are provided in
Table 1 below.

Table 1.--El Paso County CO Emissions for 2002-2015 (tpd)
----------------------------------------------------------------------------------------------------------------
2002 2005 2011 2015
----------------------------------------------------------------------------------------------------------------
Point Source.................................... 4.67 4.42 4.78 5.03
Area Source..................................... 16.42 16.80 17.61 18.17
Nonroad Mobile.................................. 45.90 48.71 55.23 59.18
Onroad Mobile................................... 360.34 325.50 245.16 232.02
=================
Total....................................... 427.33 385.43 322.78 314.40
----------------------------------------------------------------------------------------------------------------

As presented in Chapter 3, Table 3-1 of the State's maintenance
plan, ambient air quality monitoring data for consecutive calendar
years 1999 through 2004 show a measured exceedance rate of the CO NAAQS
of 1.0 or less per year, per monitor, in the El Paso nonattainment
area. To further demonstrate maintenance of the CO NAAQS, the TCEQ
agreed to additional ``hot spot'' modeling as requested by EPA on the
basis of EPA's Office of Air Quality Planning and Standards' (OAQPS)
September 30, 1994 Ozone/Carbon Monoxide Redesignations Reference
Document. The modeling was done specifically to address two concerns--
the El Paso CO monitoring network has a limited number of sites, and
therefore may not have identified all the hot spots in the El Paso
area; and in the future, urban growth may increase mobile emissions
enough to cause exceedances of the NAAQS.
The TCEQ performed CO modeling at a heavily utilized intersection
to demonstrate that CO exceedances are not currently occurring at a
potential hot spot and will not occur at that location in the future. A
modeling protocol detailing hotspot selection, proposed model usage,
and data analysis was submitted by the State on February 17, 2005, and
was approved by EPA via a letter dated March 30, 2005. The modeling
protocol and approach taken are detailed in Chapter 4 of the
maintenance plan. As shown in Table 4-2 of the maintenance plan, the
current (base) case hot spot analysis predicted a maximum 8-hour CO
concentration of 7.8 ppm, and the 2015 future case analysis predicted a
maximum 8-hour CO concentration of 2.2 ppm. Both of these values are
below the 9 ppm NAAQS, and demonstrate current and projected compliance
with the CO standard. A more detailed evaluation by EPA of this hot
spot analysis is provided in the TSD.
2. Demonstration of Maintenance--Projected Inventories
As we noted above, total CO emissions were projected forward by the
State for the years 2005, 2011, and 2015. We note the State's approach
for developing the projected inventories follows EPA guidance on
projected emissions and we believe they are acceptable.\2\ The
projected inventories show that CO emissions are not estimated to
exceed the 2002 attainment level during the time period 2002 through
2015 and, therefore, the El Paso area has satisfactorily demonstrated
maintenance. The year 2005 was selected as the year of designation of
attainment for the 8-hour CO NAAQS, so the final projection year, 2015,
was intended to represent the last year of the 10-year maintenance
plan. The year 2011 was selected as an interim year for conformity
determination. These projected inventories were developed using EPA-
approved technologies and methodologies. No new control strategies for
point and area sources were relied upon in the projected inventories.
CO emission reductions anticipated from EPA's national rule for the
Spark Ignition Small Engine Rule, Phase 1, were relied upon as a new
control strategy for Nonroad sources. TCEQ relied upon emissions
reductions anticipated from existing control strategies: FMVCP, Texas
Oxygenated Fuel SIP, and the Texas I/M Program. Please see the TSD for
more information on EPA's review and evaluation of the State's
methodologies, modeling, inputs, etc., for developing the projected
emissions inventories.

Ozone and Carbon Monoxide (CO) Nonattainment Areas'', signed by D.
Kent Berry, Acting Director, Air Quality Management Division,
November 30, 1993.
---------------------------------------------------------------------------

3. Monitoring Network and Verification of Continued Attainment
The TCEQ commits to maintain an appropriate air monitoring network
for the El Paso area throughout the 10-year maintenance period. As
required by 40 CFR Part 58.20(d), TCEQ will consult with EPA in annual
review of the air monitoring network to determine the

[[Page 2781]]

adequacy of the CO monitoring network, whether or not additional
monitoring is needed, and if/when monitor sites can be discontinued.
The TCEQ also commits to adhere to data quality requirements as
specified in 40 CFR Part 58 Quality Assurance Requirements.
Texas commits to track the progress of the maintenance plan by
continuing to periodically update the emissions inventory (EI). It will
compare the updated EIs against the projected 2005, 2011 and 2015 EIs.
TCEQ also commits to continuing all the applicable control
strategies, i.e., the measures approved into the El Paso SIP. For
example, these measures include the Federal Motor Vehicle Control
Program (FMVCP), an oxygenated fuels program, and a motor vehicle
inspection and maintenance (I/M) program.
Based on the above, we are approving these commitments as
satisfying the relevant requirements and we note that his final
rulemaking approval will render the State's commitments federally
enforceable.
4. Contingency Plan
Section 175A(d) of the CAA requires that a maintenance plan include
contingency provisions. To meet this requirement, the State has
identified appropriate contingency measures along with a schedule for
the development and implementation of such measures. In the January 20,
2006 submittal, Texas specifies the contingency trigger as a violation
of the 8-hour CO standard base upon air quality monitoring data from
the El Paso monitoring network. In the event that a monitored violation
of the 8-hour CO standard occurs in any portion of the maintenance
area, the State will first analyze the data to determine if the
violation was caused by actions outside TCEQ's jurisdiction (e.g.,
emissions from Mexico or another state) or within its jurisdiction. If
the violation was caused by actions outside TCEQ's jurisdiction, TCEQ
will notify the EPA. If TCEQ determines the violation was caused by
actions within TCEQ's jurisdiction, TCEQ commits to adopt and implement
the identified contingency measures as expeditiously as practicable,
but no later than 18 months.
The State will analyze one or more of the following contingency
measures to reattain the standard:
Vehicle idling restrictions.
Improved vehicle I/M.
Improved traffic control measures.
The maintenance plan indicates that the State may evaluate other
potential strategies to address any future violations in the most
appropriate and effective manner possible. Based on the above, we find
that the contingency measures provided in the State's El Paso CO
maintenance plan are sufficient and meet the requirements of section
175A(d) of the CAA.
5. Subsequent Maintenance Plan Revisions
In accordance with section 175A(b) of the CAA, Texas has committed
to submit a revised maintenance plan eight years after our approval of
the redesignation. This provision for revising the maintenance plan is
contained in Chapter 5, Section 5.1 of the El Paso CO maintenance plan.
The maintenance plan adequately addresses the five basic components
of a maintenance plan. EPA believes that the 8-hour CO maintenance plan
SIP revision submitted by the State of Texas for the El Paso area meets
the requirements of Section 175A of the CAA. For more information,
please refer to our Technical Support Document.

III. EPA's Evaluation of the Transportation Conformity Requirements

Table 2 documents the motor vehicle emissions budgets (MVEBs) for
the El Paso CO nonattainment area that have been established by this CO
redesignation request. The MVEB is that portion of the total allowable
emissions defined in the SIP revision allocated to on-road mobile
sources for a certain date for meeting the purpose of the SIP, in this
case maintaining compliance with the NAAQS in the nonattainment or
maintenance area. EPA's conformity rule (40 CFR part 51, subpart T and
part 93, subpart A) requires that transportation plans, programs and
projects in nonattainment or maintenance areas conform to the SIP. The
motor vehicle emissions budget is one mechanism EPA has identified for
demonstrating conformity. Upon the effective date of this SIP approval,
all future transportation improvement programs and long range
transportation plans for the El Paso area will have to show conformity
to the budgets in this plan; previous budgets approved or found
adequate will no longer be applicable.

Table 2.--El Paso CO MVEB for 2002-2015 (tpd)
------------------------------------------------------------------------
Year MVEB
------------------------------------------------------------------------
2002........................................................... 29.66
2011........................................................... 18.56
2015........................................................... 16.63
------------------------------------------------------------------------

Our analysis indicates that the above figures are consistent with
maintenance of the CO NAAQS throughout the maintenance period. In
accordance with EPA's adequacy process, these MVEBs were posted on
EPA's adequacy Web site for public notice on May 4, 2006 and were open
for comment until June 5, 2006. No comments were received during this
period. Therefore, we are finding as adequate and approving the 29.66
tpd for 2002 through 2010, 18.56 tpd for 2011 through 2014, and 16.63
tpd for 2015 and beyond, CO emissions budgets for the El Paso area.
Budget modeling was developed for TCEQ under contract by the Texas
Transportation Institute (TTI), utilizing El Paso travel model datasets
developed by the El Paso Metropolitan Planning Organization. The
modeling incorporated two onroad source control strategies that apply
in the El Paso area: The El Paso Oxygenated Fuel Program, and the I/M
program (both detailed in Chapter 5, Section 5.3.3 of the maintenance
plan).

IV. Consideration of Section 110(l) of the CAA

Section 110(l) of the CAA states that a SIP revision cannot be
approved if the revision would interfere with any applicable
requirement concerning attainment and reasonable further progress
towards attainment of a NAAQS or any other applicable requirement of
the CAA. As stated above, the El Paso area has shown continuous
attainment of the CO NAAQS since 1999 and has met the applicable
Federal requirements for redesignation to attainment. The maintenance
plan will not interfere with attainment or any other applicable
requirement of the CAA. No control measures in the El Paso SIP are
being removed.

V. Final Action

EPA is approving the redesignation of the El Paso area to
attainment of the 8-hour CO NAAQS, as well as approving the El Paso
area CO maintenance plan. We also are approving the associated MVEBs.
We have evaluated the State's submittal and have determined that it
meets the applicable requirements of the Clean Air Act and EPA
regulations, and is consistent with EPA policy.
EPA is publishing this rule without prior proposal because we view
this as a non-controversial amendment and anticipate no adverse
comments. However, in the ``Proposed Rules'' section of today's Federal
Register, we are publishing a separate document that will serve as the
proposed rule to approve the SIP revision if relevant adverse comments
are received on this

[[Page 2782]]

direct final rule. We will not institute a second comment period on
this action. Any parties interested in commenting must do so at this
time. For further information about commenting on this rule, see the
ADDRESSES section of this document.
If EPA receives adverse comment, we will publish a timely
withdrawal in the Federal Register informing the public that the rule
will not take effect. We would address all public comments in a
subsequent final rule based on the proposed rule. Please note that if
we receive adverse comment on an amendment, paragraph, or section of
this rule and if that provision may be severed from the remainder of
the rule, we may adopt as final those provisions of the rule that are
not the subject of an adverse comment.

VI. Statutory and Executive Order Reviews

Under Executive Order 12866 (58 FR 51735, October 4, 1993), this
action is not a ``significant regulatory action'' and therefore is not
subject to review by the Office of Management and Budget. For this
reason, this action is also not subject to Executive Order 13211,
``Actions Concerning Regulations That Significantly Affect Energy
Supply, Distribution, or Use'' (66 FR 28355, May 22, 2001). This action
merely approves state law as meeting Federal requirements and imposes
no additional requirements beyond those imposed by state law.
Accordingly, the Administrator certifies that this rule will not have a
significant economic impact on a substantial number of small entities
under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.). Because
this rule approves pre-existing requirements under state law and does
not impose any additional enforceable duty beyond that required by
state law, it 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).
This rule also does not have tribal implications because it will
not have a substantial direct effect on one or more Indian tribes, on
the relationship between the Federal Government and Indian tribes, or
on the distribution of power and responsibilities between the Federal
Government and Indian tribes, as specified by Executive Order 13175 (65
FR 67249, November 9, 2000). This action also does not have federalism
implications because it does not have substantial direct effects on the
States, on the relationship between the national government and the
States, or on the distribution of power and responsibilities among the
various levels of government, as specified in Executive Order 13132 (64
FR 43255, August 10, 1999). This action merely approves a state rule
implementing a Federal standard, and does not alter the relationship or
the distribution of power and responsibilities established in the CAA.
This rule also is not subject to Executive Order 13045 ``Protection of
Children from Environmental Health Risks and Safety Risks'' (62 FR
19885, April 23, 1997), because it is not economically significant.
In reviewing SIP submissions, EPA's role is to approve state
choices, provided that they meet the criteria of the Clean Air Act. In
this context, in the absence of a prior existing requirement for the
State to use voluntary consensus standards (VCS), EPA has no authority
to disapprove a SIP submission for failure to use VCS. It would thus be
inconsistent with applicable law for EPA, when it reviews a SIP
submission, to use VCS in place of a SIP submission that otherwise
satisfies the provisions of the CAA. Thus, the requirements of section
12(d) of the National Technology Transfer and Advancement Act of 1995
(15 U.S.C. 272 note) do not apply. This rule does not impose an
information collection burden under the provisions of the Paperwork
Reduction Act of 1995 (44 U.S.C. 3501 et seq.).
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 rule 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 CAA, petitions for judicial review
of this action must be filed in the United States Court of Appeals for
the appropriate circuit by March 26, 2007. Filing a petition for
reconsideration by the Administrator of this final rule does not affect
the finality of this rule 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).)
