Approval and Promulgation of Implementation Plans and Designation of Areas for Air Quality Planning Purposes; Wisconsin; Redesignation of the Manitowoc County and Door County Areas to Attainment for Ozone

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

SUMMARY: EPA is proposing to approve Wisconsin's requests to redesignate the Manitowoc County and Door County, Wisconsin nonattainment areas, to attainment for the 1997 8-hour ozone standard, because the requests meet the statutory requirements for redesignation under the Clean Air Act (CAA). The Wisconsin Department of Natural

Resources (WDNR) submitted these requests on September 11, 2009.

Page 22048

These proposed approvals involve several related actions. EPA is proposing to determine that the Manitowoc County and Door County areas have attained the 8-hour ozone National Ambient Air Quality Standard

(NAAQS). These determinations are based on three years of complete, quality-assured and certified ambient air quality monitoring data for the 2006-2008 ozone seasons that demonstrate that the 8-hour ozone

NAAQS has been attained in the areas. Complete, quality-assured air quality data for the 2009 ozone season have been recorded in the EPA's

Air Quality System (AQS) and show that the areas continue to attain the 8-hour ozone standard. EPA is also proposing to approve, as revisions to the Wisconsin State Implementation Plan (SIP), the State's plans for maintaining the 8-hour ozone NAAQS through 2020 in the areas.

EPA is proposing to approve the 2005 base year emissions inventories for the Manitowoc County and Door County areas as meeting the base year emissions inventory requirement of the CAA. WDNR submitted these base year emissions inventories on June 12, 2007.

Finally, EPA finds adequate and is proposing to approve the State's 2012 and 2020 Motor Vehicle Emission Budgets (MVEBs) for the Manitowoc

County and Door County areas.

2. What actions is EPA proposing to take?

   EPA is proposing to take several related actions. EPA is proposing to determine that the Manitowoc County and Door County nonattainment areas have attained the 1997 8-hour ozone

   Page 22049

   standard and that the areas have met the requirements for redesignation under section 107(d)(3)(E) of the CAA. EPA is thus proposing to approve the requests from WDNR to change the legal designation of the Manitowoc

   County and Door County areas from nonattainment to attainment for the 8-hour ozone NAAQS. EPA is also proposing to approve, as revisions to the Wisconsin SIP, the State's maintenance plans (such approval being one of the CAA criteria for redesignation to attainment status). The maintenance plans are designed to keep the Manitowoc County and Door

   County areas in attainment of the ozone NAAQS through 2020. EPA is proposing to approve the 2005 base year emissions inventories for the

   Manitowoc County and Door County areas as meeting the requirements of section 172(c)(3) of the CAA. If EPA's determination of attainment is finalized, under the provisions of 40 CFR 51.918, the requirement to submit certain planning SIPs related to attainment (the Reasonably

   Available Control Measure (RACM) requirement of section 172(c)(1) of the CAA, the Reasonable Further Progress (RFP) and attainment demonstration requirements of sections 172(c)(2) and (6) of the CAA, and the requirement for contingency measures of section 172(c)(9) of the CAA) are not applicable to the area as long as it continues to attain the NAAQS and would cease to be applicable upon redesignation.

   In addition, as set forth in more detail below, in the context of redesignations, EPA has interpreted requirements related to attainment as not applicable for purposes of redesignation. Finally, EPA finds adequate and is proposing to approve the newly-established 2012 and 2020 MVEBs for the Manitowoc County and Door County areas. The adequacy comment period for the MVEBs began on February 24, 2010, with EPA's posting of the availability of the submittal on EPA's Adequacy Web site

   (at http://www.epa.gov/otaq/stateresources/transconf/adequacy.htm). The adequacy comment period for these MVEBs ended on March 26, 2010. EPA did not receive any requests for this submittal, or adverse comments on this submittal during the adequacy comment period. In a letter dated

   April 7, 2010, EPA informed WDNR that we had found the 2012 and 2020

   MVEBs to be adequate for use in transportation conformity analyses.

   Please see section VI.B. of this rulemaking, ``Adequacy of Wisconsin's

   MVEBs,'' for further explanation of this process. Therefore, we find adequate, and are proposing to approve, the State's 2012 and 2020 MVEBs for transportation conformity purposes.

3. What is the background for these actions?

   1. What is the general background information?

      Ground-level ozone is not emitted directly by sources. Rather, emissions of nitrogen oxides (NOX) and volatile organic compounds (VOCs) react in the presence of sunlight to form ground-level ozone. NOXand VOCs are referred to as precursors of ozone.

      The CAA establishes a process for air quality management through the NAAQS. Before promulgation of the 8-hour standard, the ozone NAAQS was based on a 1-hour standard. On November 6, 1991 (56 FR 56693 and 56852), the Manitowoc County and Door County areas were designated as moderate and rural transport nonattainment areas, respectively, under the 1-hour ozone NAAQS. The Manitowoc County and Door County areas were subsequently redesignated to attainment of the 1-hour standard on April 17, 2003 (68 FR 18883). At the time EPA revoked the 1-hour ozone NAAQS, on June 15, 2005, the Manitowoc County and Door County areas were designated as attainment under the 1-hour ozone NAAQS.

      On July 18, 1997 (62 FR 38856), EPA promulgated an 8-hour ozone standard of 0.08 parts per million parts (ppm). On April 30, 2004 (69

      FR 23857), EPA published a final rule designating and classifying areas under the 8-hour ozone NAAQS. These designations and classifications became effective June 15, 2004. EPA designated as nonattainment any area that was violating the 8-hour ozone NAAQS based on the three most recent years of air quality data, 2001-2003.

      The CAA contains two sets of provisions, subpart 1 and subpart 2, that address planning and control requirements for nonattainment areas.

      (Both are found in Title I, part D, of the CAA; 42 U.S.C. 7501-7509a and 7511-7511f, respectively.) Subpart 1 contains general requirements for nonattainment areas for any pollutant, including ozone, governed by a NAAQS. Subpart 2 provides additional and more specific requirements for ozone nonattainment areas.

      Under EPA's implementation rule for the 1997 8-hour ozone standard,

      (69 FR 23951 (April 30, 2004)), an area was classified under subpart 2 based on its 8-hour ozone design value (i.e. the three-year average annual fourth-highest daily maximum 8-hour average ozone concentration), if it had a 1-hour design value at the time of designation at or above 0.121 ppm (the lowest 1-hour design value in

      Table 1 of subpart 2) (69 FR 23954). All other areas were covered under subpart 1, based upon their 8-hour design values (69 FR 23958). The

      Manitowoc County and Door County areas were designated as a subpart 1, 8-hour ozone nonattainment area by EPA on April 30, 2004 (69 FR 23857, 23947), based on air quality monitoring data from 2001-2003 (69 FR 23860). 40 CFR 50.10 and 40 CFR part 50, Appendix I, provide that the 8- hour ozone standard is attained when the three-year average of the annual fourth-highest daily maximum 8-hour average ozone concentration is less than or equal to 0.08 ppm, when rounded. The data completeness requirement is met when the average percent of days with valid ambient monitoring data is greater than 90%, and no single year has less than 75% data completeness. See 40 CFR part 50, Appendix I, 2.3(d).

      The WDNR submitted requests to redesignate the Manitowoc County and

      Door County areas to attainment for the 8-hour ozone standard on

      September 11, 2009. The redesignation requests included three years of complete, quality-assured data for the period of 2006 through 2008, indicating the 8-hour NAAQS for ozone, as promulgated in 1997, had been attained for the Manitowoc County and Door County areas. Complete, quality-assured monitoring data in AQS but not yet certified for the 2009 ozone season show that the areas continue to attain the 8-hour ozone standard. Under the CAA, nonattainment areas may be redesignated to attainment if sufficient complete, quality-assured data are available for the Administrator to determine that the area has attained the standard, and the area meets the other CAA redesignation requirements in section 107(d)(3)(E).

      On March 27, 2008 (73 FR 16436), EPA promulgated a revised 8-hour ozone standard of 0.075 ppm. In May 2008, States, environmental groups and industry groups filed petitions with the DC Circuit Court of

      Appeals for review of the 2008 ozone standards. In March 2009, the court granted EPA's request to stay the litigation so EPA could review the standards and determine whether they should be reconsidered. On

      September 16, 2009, we announced that we are reconsidering our 2008 decision setting national standards for ground-level ozone. The designation process for that standard has been stayed. On January 19, 2010, EPA proposed to set the level of the primary 8-hour ozone standard within the range of 0.060 to

      Page 22050

      0.070 ppm, rather than at 0.075 ppm (75 FR 2938). We expect by August 2010 to have completed our reconsideration of the standard and also expect that thereafter we will proceed with designations. The actions addressed in today's proposed rulemaking relate only to the 1997 8-hour ozone standard.

   2. What are the impacts of the December 22, 2006, and June 8, 2007,

      United States Court of Appeals decisions regarding EPA's Phase 1 implementation rule? 1. Summary of Court Decision

      On December 22, 2006, in South Coast Air Quality Management Dist. v. EPA (South Coast), the U.S. Court of Appeals for the District of

      Columbia Circuit vacated EPA's Phase 1 Implementation Rule for the 8- hour Ozone Standard (69 FR 23951, April 30, 2004). 472 F.3d 882 (DC

      Cir. 2006). On June 8, 2007, in response to several petitions for rehearing, the DC Circuit Court clarified that the Phase 1 Rule was vacated only with regard to those parts of the rule that had been successfully challenged. Id., Docket No. 04 1201. Therefore, several provisions of the Phase 1 Rule remain effective: provisions related to classifications for areas currently classified under subpart 2 of Title

      I, part D, of the CAA as 8-hour nonattainment areas; the 8-hour attainment dates; and the timing for emissions reductions needed for attainment of the 8-hour ozone NAAQS. The June 8, 2007, decision also left intact the court's rejection of EPA's reasons for implementing the 8-hour standard in certain nonattainment areas under subpart 1 in lieu of subpart 2. By limiting the vacatur, the court let stand EPA's revocation of the 1-hour standard and those anti-backsliding provisions of the Phase 1 Rule that had not been successfully challenged. The June 8, 2007, decision reaffirmed the December 22, 2006, decision that EPA had improperly failed to retain four measures required for 1-hour nonattainment areas under the anti-backsliding provisions of the regulations: (1) Nonattainment area New Source Review (NSR) requirements based on an area's 1-hour nonattainment classification;

      (2) section 185 penalty fees for 1-hour severe or extreme nonattainment areas; (3) measures to be implemented pursuant to section 172(c)(9) or 182(c)(9) of the CAA, on the contingency of an area not making reasonable further progress toward attainment of the 1-hour NAAQS, or for failure to attain that NAAQS; and (4) certain transportation conformity requirements for certain types of Federal actions. The June 8, 2007, decision clarified that the court's reference to conformity requirements was limited to requiring the continued use of 1-hour motor vehicle emissions budgets until 8-hour budgets were available for 8- hour conformity determinations.

      This section sets forth EPA's views on the potential effect of the court's rulings on these proposed redesignation actions. For the reasons set forth below, EPA does not believe that the court's rulings alter any requirements relevant to these redesignation actions so as to preclude redesignation or prevent EPA from proposing or ultimately finalizing these redesignations. EPA believes that the court's December 22, 2006, and June 8, 2007, decisions impose no impediment to moving forward with redesignation of these areas to attainment, because even in light of the court's decisions, redesignation is appropriate under the relevant redesignation provisions of the CAA and longstanding policies regarding redesignation requests. 2. Requirements Under the 8-Hour Standard

      With respect to the 8-hour standard, the court's ruling rejected

      EPA's reasons for classifying areas under subpart 1 for the 8-hour standard, and remanded that matter to the Agency. In its January 16, 2009, proposed rulemaking in response to the South Coast decision, EPA has proposed to classify Door County and Manitowoc County under subpart 2 as moderate and marginal areas, respectively (74 FR 2936, 2944). If

      EPA finalizes this rulemaking, the requirements under subpart 2 will become applicable when they are due, a deadline that EPA has proposed to be one year after the effective date of a final rulemaking classifying areas as moderate or marginal (74 FR 2940-2941). Although a future final decision by EPA to classify these areas under subpart 2 would trigger additional future requirements for the areas, EPA believes that this does not mean that redesignations cannot now go forward. This belief is based upon: (1) EPA's longstanding policy of evaluating requirements in accordance with the requirements due at the time the request is submitted; and, (2) consideration of the inequity of applying retroactively any requirements that might be applied in the future.

      First, at the time the redesignation requests were submitted, the

      Manitowoc County and Door County areas were not classified under subpart 2, nor were there any subpart 2 requirements yet due for these areas. Under EPA's longstanding interpretation of section 107(d)(3)(E) of the CAA, to qualify for redesignation, States requesting redesignation to attainment must meet only the relevant SIP requirements that came due prior to the submittal of a complete redesignation request. See September 4, 1992, Calcagni memorandum

      (``Procedures for Processing Requests to Redesignate Areas to

      Attainment,'' Memorandum from John Calcagni, Director, Air Quality

      Management Division). See also Michael Shapiro Memorandum, September 17, 1993, and 60 FR 12459, 12465-12466 (March 7, 1995) (Redesignation of Detroit-Ann Arbor). See Sierra Club v. EPA, 375 F.3d 537 (7th Cir. 2004), which upheld EPA's redesignation rulemaking applying this interpretation. See, e.g. also 68 FR 25418, 25424, 25427 (May 12, 2003)

      (Redesignation of St. Louis).

      Moreover, it would be inequitable to retroactively apply any new

      SIP requirements that were not applicable at the time the request was submitted. The DC Circuit has recognized the inequity in such retroactive rulemaking. In Sierra Club v. Whitman, 285 F.3d 63 (DC Cir. 2002), the DC Circuit upheld a district court's ruling refusing to make retroactive an EPA determination of nonattainment that was past the statutory due date. Such a determination would have resulted in the imposition of additional requirements on the area. The court stated:

      ``Although EPA failed to make the nonattainment determination within the statutory time frame, Sierra Club's proposed solution only makes the situation worse. Retroactive relief would likely impose large costs on the States, which would face fines and suits for not implementing air pollution prevention plans in 1997, even though they were not on notice at the time.'' Id. at 68. Similarly here it would be unfair to penalize the areas by applying to them, for purposes of redesignation, additional SIP requirements under subpart 2 that were not in effect or yet due at the time WDNR submitted its redesignation requests. 3. Requirements Under the 1-Hour Standard

      With respect to the 1-hour standard requirements, the Manitowoc

      County and Door County areas were attainment areas subject to CAA section 175A maintenance plans under the 1-hour standard at the time that the 1-hour standard was revoked. Therefore, the DC Circuit's decisions with respect to 1-hour nonattainment anti-backsliding requirements do not impact redesignation requests for these types of areas, except to the extent that the court

      Page 22051

      in its June 8, 2007, decision clarified that for those areas with 1- hour motor vehicle emissions budgets in their maintenance plans, anti- backsliding requires that those 1-hour budgets must be used for 8-hour conformity determinations until replaced by 8-hour budgets. To meet this requirement, conformity determinations in such areas must comply with the applicable requirements of EPA's conformity regulations at 40

      CFR part 93.

      With respect to the three other anti-backsliding provisions for the 1-hour standard that the court found were not properly retained, the

      Manitowoc County and Door County areas are attainment areas subject to maintenance plans for the 1-hour standard, and the NSR, contingency measures (pursuant to section 172(c)(9) or 182(c)(9)), and fee provision requirements no longer apply to areas that have been redesignated to attainment of the 1-hour standard.

      Thus, the South Coast decision in South Coast Air Quality

      Management Dist. does not preclude EPA from finalizing the redesignation of these areas.

4. What are the criteria for redesignation?

   The CAA provides the requirements for redesignating a nonattainment area to attainment. Specifically, section 107(d)(3)(E) allows for redesignation provided that: (1) The Administrator determines that the area has attained the applicable NAAQS; (2) the Administrator has fully approved the applicable implementation plan for the area under section 110(k); (3) the Administrator determines that the improvement in air quality is due to permanent and enforceable reductions in emissions resulting from implementation of the applicable SIP and applicable

   Federal air pollutant control regulations and other permanent and enforceable reductions; (4) the Administrator has fully approved a maintenance plan for the area as meeting the requirements of section 175A; and, (5) the State containing such area has met all requirements applicable to the area under section 110 and part D.

   EPA provided guidance on redesignation in the General Preamble for the Implementation of Title I of the CAA Amendments of 1990 on April 16, 1992 (57 FR 13498), and supplemented this guidance on April 28, 1992 (57 FR 18070). EPA has provided further guidance on processing redesignation requests in the following documents:

   ``Ozone and Carbon Monoxide Design Value Calculations,'' Memorandum from William G. Laxton, Director Technical Support Division, June 18, 1990;

   ``Maintenance Plans for Redesignation of Ozone and Carbon Monoxide

   Nonattainment Areas,'' Memorandum from G. T. Helms, Chief, Ozone/Carbon

   Monoxide Programs Branch, April 30, 1992;

   ``Contingency Measures for Ozone and Carbon Monoxide (CO)

   Redesignations,'' Memorandum from G. T. Helms, Chief, Ozone/Carbon

   Monoxide Programs Branch, June 1, 1992;

   ``Procedures for Processing Requests to Redesignate Areas to

   Attainment,'' Memorandum from John Calcagni, Director, Air Quality

   Management Division, September 4, 1992;

   ``State Implementation Plan (SIP) Actions Submitted in Response to

   Clean Air Act (ACT) Deadlines,'' Memorandum from John Calcagni,

   Director, Air Quality Management Division, October 28, 1992;

   ``Technical Support Documents (TSDs) for Redesignation Ozone and

   Carbon Monoxide (CO) Nonattainment Areas,'' Memorandum from G. T.

   Helms, Chief, Ozone/Carbon Monoxide Programs Branch, August 17, 1993;

   ``State Implementation Plan (SIP) Requirements for Areas Submitting

   Requests for Redesignation to Attainment of the Ozone and Carbon

   Monoxide (CO) National Ambient Air Quality Standards (NAAQS) On or

   After November 15, 1992,'' Memorandum from Michael H. Shapiro, Acting

   Assistant Administrator for Air and Radiation, September 17, 1993;

   ``Use of Actual Emissions in Maintenance Demonstrations for Ozone and CO Nonattainment Areas,'' Memorandum from D. Kent Berry, Acting

   Director, Air Quality Management Division, to Air Division Directors,

   Regions 1-10, November 30, 1993.

   ``Part D New Source Review (part D NSR) Requirements for Areas

   Requesting Redesignation to Attainment,'' Memorandum from Mary D.

   Nichols, Assistant Administrator for Air and Radiation, October 14, 1994; and

   ``Reasonable Further Progress, Attainment Demonstration, and

   Related Requirements for Ozone Nonattainment Areas Meeting the Ozone

   National Ambient Air Quality Standard,'' Memorandum from John S. Seitz,

   Director, Office of Air Quality Planning and Standards, May 10, 1995.

5. What is the effect of these actions?

   Approval of the redesignation requests would change the official designations of the Manitowoc County and Door County areas for the 1997 8-hour ozone NAAQS found at 40 CFR part 81. It would also incorporate into the Wisconsin SIP plans for maintaining the 8-hour ozone NAAQS through 2020. The maintenance plans include contingency measures as required under CAA section 175A to remedy future violations of the 8- hour NAAQS. They also establish MVEBs for the Manitowoc County area of 1.76 and 1.25 tons per day (tpd) for VOC and 3.76 and 1.86 tpd for

   NOXfor the years 2012 and 2020, respectively, and MVEBs for the Door County area of 0.78 and 0.53 tpd for VOC and 1.55 and 0.74 tpd for NOXfor the years 2012 and 2020, respectively.

6. What is EPA's analysis of the request?

   1. Attainment Determinations and Redesignations

      EPA is proposing to determine that the Manitowoc County and Door

      County areas have attained the 1997 8-hour ozone standard and that the areas have met all other applicable redesignation criteria under CAA section 107(d)(3)(E). The basis for EPA's proposed approvals of the redesignation requests is as follows: 1. The Areas Have Attained the 8-Hour Ozone NAAQS (Section 107(d)(3)(E)(i))

      EPA is proposing to make determinations that the Manitowoc County and Door County areas have attained the 1997 8-hour ozone NAAQS. An area may be considered to be attaining the 8-hour ozone NAAQS if there are no violations, as determined in accordance with 40 CFR 50.10 and part 50, Appendix I, based on three complete, consecutive calendar years of quality-assured air quality monitoring data. To attain this standard, the three-year average of the fourth-highest daily maximum 8- hour average ozone concentrations measured at each monitor within an area over each year must not exceed 0.08 ppm. Based on the rounding convention described in 40 CFR part 50, Appendix I, the standard is attained if the design value is 0.084 ppm or below. The data must be collected and quality-assured in accordance with 40 CFR part 58, and recorded in AQS. The monitors generally should have remained at the same location for the duration of the monitoring period required for demonstrating attainment.

      Wisconsin included in its redesignation requests ozone monitoring data for the 2006 to 2008 ozone seasons and has subsequently provided monitoring data for 2009. Monitoring data for 2006 through 2008 have been certified by the State; 2009 data have

      Page 22052

      not yet been certified. However, Wisconsin has quality-assured all of the ambient monitoring data in accordance with 40 CFR 58.10, and has recorded it in the AQS database. The data meet the completeness criteria in 40 CFR 50, Appendix I, which require a minimum completeness of 75 percent annually and 90 percent over each three-year period.

      Monitoring data are presented in Table 1 below.

      In addition, as discussed below with respect to the maintenance plans, WDNR has committed to continue to operate an EPA-approved monitoring network in the areas. WDNR will continue to quality assure monitoring data in accordance with 40 CFR part 58 and enter all data into AQS in accordance with Federal guidelines. In summary, EPA believes that the data show that the Manitowoc County and Door County areas have attained the 8-hour ozone NAAQS. 2. The Areas Have Met All Applicable Requirements Under Section 110 and

      Part D; and the Areas Have Fully Approved SIPs Under Section 110(k)

      (Sections 107(d)(3)(E)(v) and 107(d)(3)(E)(ii))

      We have determined that Wisconsin has met all currently applicable

      SIP requirements for purposes of redesignation for the Manitowoc County and Door County areas under section 110 of the CAA (general SIP requirements). We are also proposing to determine that the Wisconsin

      SIP meets all SIP requirements for these areas currently applicable for purposes of redesignation under part D of Title I of the CAA

      (requirements specific to subpart 1 nonattainment areas), in accordance with section 107(d)(3)(E)(v). In addition, with the exception of the base year emissions inventories, we have approved all applicable requirements of the Wisconsin SIP for purposes of redesignation, in accordance with section 107(d)(3)(E)(ii). As discussed below, in this action EPA is proposing to approve Wisconsin's 2005 base year emissions inventories as meeting the section 172(c)(3) emissions inventory requirement for the areas.

      In proposing these determinations, we have ascertained which SIP requirements are applicable to the areas for purposes of redesignation, and have determined that there are SIP measures meeting those requirements and that they are, or upon final approval of the emissions inventories, will be fully approved under section 110(k) of the CAA. As discussed more fully below, for purposes of evaluating a redesignation request, SIPs must be fully approved only with respect to requirements that became due prior to the submission of the redesignation request.

      The September 4, 1992, Calcagni memorandum (see ``Procedures for

      Processing Requests to Redesignate Areas to Attainment,'' Memorandum from John Calcagni, Director, Air Quality Management Division,

      September 4, 1992) describes EPA's interpretation of section 107(d)(3)(E) of the CAA. Under this interpretation, a State and the area it wishes to redesignate must meet the relevant CAA requirements that are due prior to the State's submittal of a complete redesignation request for the area. See also the September 17, 1993, Michael Shapiro memorandum and 60 FR 12459, 12465-12466 (March 7, 1995) (Redesignation of Detroit-Ann Arbor, Michigan to attainment of the 1-hour ozone

      NAAQS). Applicable requirements of the CAA that come due subsequent to the State's submittal of a complete request remain applicable until a redesignation to attainment is approved, but are not required as a prerequisite to redesignation. See section 175A(c) of the CAA. Sierra

      Club v. EPA, 375 F.3d 537 (7th Cir. 2004). See also 68 FR 25424, 25427

      (May 12, 2003) (Redesignation of the St. Louis/East St. Louis area to attainment of the 1-hour ozone NAAQS).

      Since EPA is proposing here to determine that the areas have attained the 1997 8-hour ozone standard, under 40 CFR 51.918, if these determinations are finalized, the requirements to submit certain planning SIPs related to attainment, including attainment demonstration requirements (the RACM requirement of section 172(c)(1) of the CAA, the

      RFP and attainment demonstration requirements of sections 172(c)(2) and

      (c)(6) of the CAA, and the requirement for contingency measures of section 172(c)(9) of the CAA), would not be applicable to the areas as long as they continue to attain the NAAQS and would cease to apply upon redesignation. In addition, in the context of redesignations, EPA has interpreted requirements related to attainment as not applicable for purposes of redesignation. For example, in the General Preamble EPA stated that:

      t he section 172(c)(9) requirements are directed at ensuring

      RFP and attainment by the applicable date. These requirements no longer apply when an area has attained the standard and is eligible for redesignation. Furthermore, section 175A for maintenance plans *

      * * provides specific requirements for contingency measures that effectively supersede the requirements of section 172(c)(9) for these areas. ``General Preamble for the Interpretation of Title I of the Clean Air Act Amendments of 1990,'' (General Preamble) 57 FR 13498, 13564 (April 16, 1992).

      See also Calcagni memorandum at 6 (``The requirements for reasonable further progress and other measures needed for attainment will not apply for redesignations because they only have meaning for areas not attaining the standard.''). a. The Manitowoc County and Door County Areas Have Met All Applicable

      Requirements for Purposes of Redesignation Under Section 110 and Part D of the CAA i. Section 110 General SIP requirements

      Section 110(a) of Title I of the CAA contains the general requirements for a SIP. Section 110(a)(2) provides that the implementation plan submitted by a State must have been adopted by the

      State after reasonable public notice and hearing, and, among other things, must: Include enforceable emission limitations and other control measures, means or techniques necessary to meet the requirements of the CAA; provide for establishment and operation of appropriate devices, methods, systems and procedures necessary to monitor ambient air quality; provide for implementation of a source permit

      Page 22053

      program to regulate the modification and construction of any stationary source within the areas covered by the plan; include provisions for the implementation of part C, Prevention of Significant Deterioration (PSD) and part D, NSR permit programs; include criteria for stationary source emission control measures, monitoring, and reporting; include provisions for air quality modeling; and provide for public and local agency participation in planning and emission control rule development.

      Section 110(a)(2)(D) of the CAA requires that SIPs contain measures to prevent sources in a State from significantly contributing to air quality problems in another State. To implement this provision, EPA has required certain States to establish programs to address transport of air pollutants (NOXSIP Call \1\ and Clean Air Interstate

      Rule (CAIR) (70 FR 25162, May 12, 2005)). However, the section 110(a)(2)(D) requirements for a State are not linked with a particular nonattainment area's designation and classification. EPA believes that the requirements linked with a particular nonattainment area's designation and classification are the relevant measures to evaluate in reviewing a redesignation request. The transport SIP submittal requirements, where applicable, continue to apply to a State regardless of the designation of any one particular area in the State. Thus, we believe that these requirements should not be construed to be applicable requirements for purposes of redesignation.

      \1\ On October 27, 1998 (63 FR 57356), EPA issued a

      NOXSIP Call requiring the District of Columbia and 22

      States to reduce emissions of NOXin order to reduce the transport of ozone and ozone precursors. Wisconsin was not included in EPA's NOXSIP Call.

      Further, we believe that the other section 110 elements described above that are not connected with nonattainment plan submissions and not linked with an area's attainment status are also not applicable requirements for purposes of redesignation. A State remains subject to these requirements after an area is redesignated to attainment. We conclude that only the section 110 and part D requirements that are linked with a particular area's designation and classification are the relevant measures that we may consider in evaluating a redesignation request. This approach is consistent with EPA's existing policy on applicability of conformity and oxygenated fuels requirements for redesignation purposes, as well as with section 184 ozone transport requirements. See Reading, Pennsylvania, proposed and final rulemakings

      (61 FR 53174-53176, October 10, 1996), (62 FR 24826, May 7, 1997);

      Cleveland-Akron-Lorain, Ohio, final rulemaking (61 FR 20458, May 7, 1996); and Tampa, Florida, final rulemaking (60 FR 62748, December 7, 1995). See also the discussion on this issue in the Cincinnati, Ohio 1- hour ozone redesignation (65 FR 37890, June 19, 2000), and in the

      Pittsburgh, Pennsylvania 1-hour ozone redesignation (66 FR 50399,

      October 19, 2001).

      We have reviewed Wisconsin's SIP and have concluded that it meets the general SIP requirements under section 110 of the CAA to the extent they are applicable for purposes of redesignation. EPA has previously approved provisions of the Wisconsin SIP addressing section 110 elements under the 1-hour ozone standard (40 CFR 52.2570). Further, in a submittal dated December 12, 2007, Wisconsin confirmed that the State continues to meet the section 110 requirements for the 8-hour ozone standard. EPA has not yet taken rulemaking action on this submittal; however, such approval is not necessary for redesignation. ii. Part D Requirements

      EPA has determined that, if EPA finalizes the approval of the base year emissions inventories discussed in section VI.C. of this rulemaking, the Wisconsin SIP will meet the applicable SIP requirements for the Manitowoc County and Door County areas applicable for purposes of redesignation under part D of the CAA. Subpart 1 of part D, found in sections 172-176 of the CAA, sets forth the basic nonattainment requirements applicable to all nonattainment areas. Subpart 2 of part

      D, which includes section 182 of the CAA, establishes additional specific requirements depending on the area's nonattainment classification.

      Since the Manitowoc County and Door County areas were not classified under subpart 2, of Part D at the time the redesignation requests were submitted, the subpart 2 requirements do not apply for purposes of evaluating the State's redesignation requests. The applicable subpart 1 requirements are contained in sections 172(c)(1)-

      (9) and in section 176.

      Subpart 1 Section 172 Requirements

      For purposes of evaluating these redesignation requests, the applicable section 172 SIP requirements for the Manitowoc County and

      Door County areas are contained in sections 172(c)(1)-(9). A thorough discussion of the requirements contained in section 172 can be found in the General Preamble for Implementation of Title I (57 FR 13498, April 16, 1992).

      Section 172(c)(1) requires the plans for all nonattainment areas to provide for the implementation of all RACM as expeditiously as practicable and to provide for attainment of the primary NAAQS. EPA interprets this requirement to impose a duty on all nonattainment areas to consider all available control measures and to adopt and implement such measures as are reasonably available for implementation in each area as components of the area's attainment demonstration. Because attainment has been reached, no additional measures are needed to provide for attainment, and section 172(c)(1) requirements are no longer considered to be applicable as long as the area continues to attain the standard until redesignation. (40 CFR 51.918).

      The RFP requirement under section 172(c)(2) is defined as progress that must be made toward attainment. This requirement is not relevant for purposes of redesignation because the Manitowoc County and Door

      County areas have monitored attainment of the ozone NAAQS. (General

      Preamble, 57 FR 13564). See also 40 CFR 51.918. In addition, because the Manitowoc County and Door County areas have attained the ozone

      NAAQS and are no longer subject to an RFP requirement, the requirement to submit the section 172(c)(9) contingency measures is not applicable for purposes of redesignation. Id.

      Section 172(c)(3) requires submission and approval of a comprehensive, accurate and current inventory of actual emissions.

      Wisconsin submitted 2005 base year emissions inventories on June 12, 2007. As discussed below in section VI.C., EPA is proposing to approve the 2005 base year inventories as meeting the section 172(c)(3) emissions inventory requirement for the Manitowoc County and Door

      County areas.

      Section 172(c)(4) requires the identification and quantification of allowable emissions for major new and modified stationary sources in an area, and section 172(c)(5) requires source permits for the construction and operation of new and modified major stationary sources anywhere in the nonattainment area. EPA approved Wisconsin's current

      NSR program on December 17, 2008 (73 FR 76558 and 76560). Nonetheless,

      EPA has determined that, since PSD requirements will apply after redesignation, areas being redesignated need not comply with the requirement that a nonattainment NSR program be

      Page 22054

      approved prior to redesignation, provided that the area demonstrates maintenance of the NAAQS without part D NSR. A more detailed rationale for this view is described in a memorandum from Mary Nichols, Assistant

      Administrator for Air and Radiation, dated October 14, 1994, entitled,

      ``Part D New Source Review Requirements for Areas Requesting

      Redesignation to Attainment.'' Wisconsin has demonstrated that the

      Manitowoc County and Door County areas will be able to maintain the standard without part D NSR in effect; therefore, the State need not have a fully approved part D NSR program prior to approval of the redesignation request. The State's PSD program will become effective in the Manitowoc County and Door County areas upon redesignation to attainment. See rulemakings for Detroit, Michigan (60 FR 12467-12468,

      March 7, 1995); Cleveland-Akron-Lorain, Ohio (61 FR 20458, 20469-20470,

      May 7, 1996); Louisville, Kentucky (66 FR 53665, October 23, 2001); and

      Grand Rapids, Michigan (61 FR 31834-31837, June 21, 1996).

      Section 172(c)(6) requires the SIP to contain control measures necessary to provide for attainment of the standard. Because attainment has been reached, no additional measures are needed to provide for attainment.

      Section 172(c)(7) requires the SIP to meet the applicable provisions of section 110(a)(2). As noted above, we believe the

      Wisconsin SIP meets the requirements of section 110(a)(2) applicable for purposes of redesignation.

      Subpart 1 Section 176 Conformity Requirements

      Section 176(c) of the CAA requires States to establish criteria and procedures to ensure that Federally-supported or funded activities, including highway projects, conform to the air quality planning goals in the applicable SIPs. The requirement to determine conformity applies to transportation plans, programs and projects developed, funded or approved under Title 23 of the U.S. Code and the Federal Transit Act

      (transportation conformity) as well as to all other Federally-supported or funded projects (general conformity). State conformity revisions must be consistent with Federal conformity regulations relating to consultation, enforcement, and enforceability, which EPA promulgated pursuant to CAA requirements.

      EPA believes that it is reasonable to interpret the conformity SIP requirements as not applying for purposes of evaluating the redesignation request under section 107(d) for two reasons. First, the requirement to submit SIP revisions to comply with the conformity provisions of the CAA continues to apply to areas after redesignation to attainment since such areas would be subject to a section 175A maintenance plan. Second, EPA's Federal conformity rules require the performance of conformity analyses in the absence of Federally-approved

      State rules. Therefore, because areas are subject to the conformity requirements regardless of whether they are redesignated to attainment and, because they must implement conformity under Federal rules if

      State rules are not yet approved, EPA believes it is reasonable to view these requirements as not applying for purposes of evaluating a redesignation request. See Wall v. EPA, 265 F.3d 426 (6th Cir. 2001), upholding this interpretation. See also 60 FR 62748, 62749-62750 (Dec. 7, 1995) (Tampa, Florida).

      EPA approved Wisconsin's general and transportation conformity SIPs on July 29, 1996 (61 FR 39329), and August 27, 1996 (61 FR 43970), respectively. Section 176(c) of the CAA was amended by provisions contained in the Safe, Accountable, Flexible, Efficient Transportation

      Equity Act: A Legacy for Users (SAFETEALU), which was signed into law on August 10, 2005 (Pub. L. 109-59). Among the changes Congress made to this section of the CAA were streamlined requirements for State conformity SIPs. Wisconsin is in the process of updating its transportation conformity SIP to meet these new requirements. Wisconsin has submitted onroad MVEBs for the Manitowoc County area of 1.76 and 1.25 tpd VOC and 3.76 and 1.86 tpd NOXfor the years 2012 and 2020, respectively and MVEBs for the Door County area of 0.78 and 0.53 tpd VOC and 1.55 and 0.74 tpd NOXfor the years 2012 and 2020, respectively. The areas must use the MVEBs from the maintenance plans in any conformity determination that is effective on or after the effective date of the adequacy finding and/or the maintenance plans' approval. b. The Manitowoc County and Door County Areas Have Fully Approved

      Applicable SIPs under Section 110(k) of the CAA

      If EPA issues a final approval of the base year emissions inventories, EPA will have fully approved the Wisconsin SIP for the

      Manitowoc County and Door County areas under section 110(k) of the CAA for all requirements applicable for purposes of redesignation. EPA may rely on prior SIP approvals in approving a redesignation request (See page 3 of the September 4, 1992, John Calcagni memorandum; Southwestern

      Pennsylvania Growth Alliance v. Browner, 144 F.3d 984, 989-990 (6th

      Cir. 1998); Wall v. EPA, 265 F.3d 426 (6th Cir. 2001)) plus any additional measures it may approve in conjunction with a redesignation action. See 68 FR 25413, 25426 (May 12, 2003). Since the passage of the

      CAA of 1970, Wisconsin has adopted and submitted, and EPA has fully approved, provisions addressing various required SIP elements under the 1-hour ozone standard. In this action, EPA is proposing to approve

      Wisconsin's 2005 base year emissions inventories for the Manitowoc

      County and Door County areas as meeting the requirement of section 172(c)(3) of the CAA. No Manitowoc County or Door County area SIP provisions are currently disapproved, conditionally approved, or partially approved. 3. The Improvement in Air Quality Is Due to Permanent and Enforceable

      Reductions in Emissions Resulting From Implementation of the SIP and

      Applicable Federal Air Pollution Control Regulations and Other

      Permanent and Enforceable Reductions (Section 107(d)(3)(E)(iii))

      EPA finds that Wisconsin has demonstrated that the observed air quality improvement in the Manitowoc County and Door County areas is due to permanent and enforceable reductions in emissions resulting from implementation of the SIPs, Federal measures, and other State-adopted measures.

      In making this demonstration, WDNR has calculated the change in emissions between 2002 and 2007. Wisconsin developed an emissions inventory for 2002, one of the years used to designate the areas as nonattainment. The State developed an attainment inventory for 2007, one of the years the Manitowoc County and Door County areas monitored attainment. The reduction in emissions and the corresponding improvement in air quality over this time period can be attributed to a number of regulatory control measures that Manitowoc and Door Counties and upwind areas have implemented in recent years. a. Permanent and Enforceable Controls Implemented

      The following is a discussion of permanent and enforceable measures that have been implemented in the areas:

      Page 22055

      i. Federal Emission Control Measures

      Reductions in VOC and NOXemissions have occurred statewide and in upwind areas as a result of Federal emission control measures, with additional emission reductions expected to occur in the future. Federal emission control measures include the following.

      Tier 2 Emission Standards for Vehicles and Gasoline Sulfur

      Standards. These emission control requirements result in lower VOC and

      NOXemissions from new cars and light duty trucks, including sport utility vehicles. The Federal rules were phased in between 2004 and 2009. The EPA has estimated that, by the end of the phase-in period, the following vehicle NOXemission reductions will occur nationwide: Passenger cars (light duty vehicles) (77 percent); light duty trucks, minivans, and sports utility vehicles (86 percent); and, larger sports utility vehicles, vans, and heavier trucks (69 to 95 percent). VOC emission reductions are expected to range from 12 to 18 percent, depending on vehicle class, over the same period. Some of these emission reductions occurred by the 2007-2009 period used to demonstrate attainment, and additional emission reductions will occur during the maintenance period.

      Heavy-Duty Diesel Engine Rule. EPA issued this rule in July 2000.

      This rule includes standards limiting the sulfur content of diesel fuel, which went into effect in 2004. A second phase took effect in 2007 which further reduced the highway diesel fuel sulfur content to 15 ppm, leading to additional reductions in combustion NOXand

      VOC emissions. This rule is expected to achieve a 95 percent reduction in NOXemissions from diesel trucks and busses.

      Non-Road Diesel Rule. EPA issued this rule in 2004. This rule applies to diesel engines used in industries, such as construction, agriculture, and mining. It is estimated that compliance with this rule will cut NOXemissions from non-road diesel engines by up to 90 percent. This rule is currently achieving emission reductions, but will not be fully implemented until 2010.

      Maximum Achievable Control Technology (MACT) Rules. EPA has promulgated numerous MACT standards, many of which limit VOC emissions.

      Compliance began for many of the MACT rules from late 2005 through 2007. ii. Control Measures in Upwind Areas

      NOX Reasonably Available Control Technology (RACT). Wisconsin adopted NOXRACT regulations for the upwind Milwaukee-Racine area. The emission requirements apply to stationary combustion units at major sources, with compliance required by May 1, 2009. The RACT rule is estimated to achieve reductions of over 29,000 tpy of NOX emissions from 2002 levels.

      NOX SIP Call. On October 27, 1998 (63 FR 57356), EPA issued a

      NOXSIP Call requiring the District of Columbia and 22

      States to reduce emissions of NOX. Affected States were required to comply with Phase I of the SIP Call beginning in 2004, and

      Phase II beginning in 2007. The reduction in NOXemissions has resulted in lower concentrations of transported ozone entering the

      Manitowoc County and Door County areas. Emission reductions resulting from regulations developed in response to the NOXSIP Call are permanent and enforceable. b. Emission Reductions

      States are required to develop periodic emissions inventories every three years. (40 CFR part 51, subpart A). Wisconsin is using the periodic emissions inventory from 2002 as the nonattainment inventory.

      Point source sector emissions inventories were developed using reported point source emissions, EPA's Clean Air Markets database and approved

      EPA techniques for emissions calculations. Emissions were estimated by collecting process-level information from each facility that qualifies for inclusion into WDNR's point source database. Process, boiler, fugitive and tank emissions were typically calculated using throughput information multiplied by an emission factor for the process. Emission factor sources included mass balance, stack testing, continuous emissions monitors, engineering judgment and EPA's Factor Information

      Retrieval database.

      Area source emissions were generated by backcasting from the 2005 periodic emissions inventory to minimize differences between the nonattainment and attainment inventories due to changes in methodology.

      The backcasting factors were based on 2002-2008 growth factors including the Census Bureau's County Business Pattern employment data, growth factors developed for the Lake Michigan Air Directors Consortium

      (LADCO) by E.H. Pechan & Associates, Inc. (Pechan); and the Economic

      Growth Analysis System (EGAS6.0). Area source emissions estimates for the 2005 periodic inventory were calculated using population, gasoline consumption, employment, crop acreages, and other activity surrogates.

      The results of an EPA Solvent Mass Balance study were used to estimate emissions for some categories. Emission factors were derived from local data, local or national surveys and EPA guidance for the development of emissions inventories. Point source emissions were subtracted from total category specific area source emissions to prevent double counting.

      Nonroad mobile source emissions were calculated using EPA's

      National Mobile Inventory Model (NMIM) and emissions estimates developed for commercial marine vessels, aircraft, and railroads (MAR), three nonroad categories not included in NMIM. Before NMIM was run, the following modifications and additions were made to the NMIM input data:

      (1) Revised activity data for construction equipment using updates provided by Pechan; (2) revised allocation data for recreational marine equipment using updates provided by ENVIRON International Corporation

      (ENVIRON); (3) added emission factors for diesel tampers/rammers provided by Pechan; (4) revised population data for construction and recreational marine equipment using updates provided by Pechan and

      ENVIRON, respectively; (5) revised growth rates using updates provided by Pechan; and (6) revised gasoline parameters, including Reid Vapor

      Pressure, oxygenate content and sulfur content, using updates provided by the States and Pechan. Onroad mobile source emissions were calculated using the MOBILE6.2 emissions model.

      Wisconsin developed a 2007 attainment year inventory using the methodologies described above to estimate point, nonroad mobile and onroad mobile sector emissions. Area source emissions were generated by applying growth factors and applicable emission controls to the 2005 area source sector inventory. Growth factors include the Census

      Bureau's County Business Pattern employment data, growth factors developed for LADCO by Pechan; and EGAS6.0.

      Using the inventories described above, Wisconsin's submittal documents changes in VOC and NOXemissions from 2002 to 2007 for the Manitowoc County and Door County areas. Because Manitowoc and

      Door Counties are impacted by transport, WDNR also documented emissions reductions for the upwind Wisconsin areas of Sheboygan and Milwaukee-

      Racine. Emissions data are shown in Tables 2 through 6 below.

      Table 4 shows that the Manitowoc County area reduced VOC emissions by 1.85 tpd and NOXemissions by 2.32 tpd between 2002 and 2007. Table 5 shows that the Door County area reduced VOC emissions by 1.23 tpd and NOXemissions by 2.17 tpd between 2002 and 2007. In addition, as shown in Table 6, the upwind areas of Sheboygan and Milwaukee-Racine reduced VOC emissions by 39.90 tpd and

      NOXemissions by 125.08 tpd between 2002 and 2007. Based on the information summarized above, Wisconsin has adequately demonstrated that the improvement in air quality is due to permanent and enforceable emissions reductions. 4. The Area Has a Fully Approved Maintenance Plan Pursuant to Section 175A of the CAA (Section 107(d)(3)(E)(iv))

      In conjunction with its requests to redesignate the Manitowoc

      County and Door County nonattainment areas to attainment status,

      Wisconsin submitted SIP revisions to provide for the maintenance of the 8-hour ozone NAAQS in the areas through 2020. a. What is required in a maintenance plan?

      Section 175A of the CAA sets forth the required elements of a maintenance plan for areas seeking redesignation from nonattainment to attainment. Under section 175A, the 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 redesignation, the State must submit a revised maintenance plan which demonstrates that attainment will continue to be maintained for ten years 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 implementation as EPA deems necessary to assure prompt correction of any future 8-hour ozone violations.

      The September 4, 1992, John Calcagni memorandum provides additional guidance on the content of a maintenance plan. The memorandum clarifies that an ozone maintenance plan should address the following items: the attainment VOC and NOXemissions inventories, a maintenance demonstration showing maintenance for the ten years of the maintenance period, a commitment to maintain the existing monitoring network, factors and procedures to be used for verification of continued attainment of the NAAQS, and a contingency plan to prevent or correct future violations of the NAAQS. b. Attainment Inventory

      The WDNR developed emissions inventories for 2007, one of the years used to demonstrate monitored attainment of the 8-hour NAAQS, as described above. The attainment level of emissions is summarized in

      Table 3, above. c. Demonstration of Maintenance

      Along with the redesignation requests, WDNR submitted revisions to the Wisconsin 8-hour ozone SIP to include maintenance plans for the

      Manitowoc County and Door County areas, as required by section 175A of the CAA. These demonstrations show maintenance of the 8-hour ozone standard through 2020 by showing that current and future emissions of

      VOC and NOXfor the areas remain at or below attainment year emission levels. A maintenance demonstration need not be based on modeling. See Wall v. EPA, 265 F.3d 426 (6th Cir. 2001), Sierra Club v.

      EPA, 375 F. 3d 537 (7th Cir. 2004). See also 66 FR 53094, 53099-53100

      (October 19, 2001), 68 FR 25413, 25430-25432 (May 12, 2003).

      Wisconsin is using emissions inventory projections for the years 2012 and 2020 to demonstrate maintenance. Emissions estimates were generated for point sources, area sources, and the MAR portion of the nonroad mobile sector by applying growth factors and applicable emission controls to the 2005 emissions inventory. The 2005 emissions inventory was developed following the same methodologies described for the 2002 inventory, in section VI.A.3.b., above. Growth factors include the Census Bureau's County Business Pattern employment data, growth factors developed for LADCO by Pechan; and EGAS6.0. Growth factors were only available for emission projections to 2018. Emissions for 2020 were estimated using linear interpolation from 2018. For Electric

      Generating Unit (EGU) point sources, projections were performed on a facility by facility basis. The growth in generation emissions considers corporate utility growth in electricity demand and the potential dispatch by the regional Midwest Independent Transmission

      System Operator to meet broader demand. The growth in electricity consumption by load type is based on growth rate projections by the

      Wisconsin Public Service Commission and historic growth rates. Nonroad mobile emissions, excluding MAR, were calculated using NMIM with the modifications and additions to the input data described in section

      VI.A.3.b., above. Onroad mobile source emissions were calculated using the MOBILE6.2 emissions model. Emissions data are shown in Tables 7 through 11, below.

      The emission projections show that Wisconsin does not expect emissions in the Manitowoc County and Door County areas to exceed the level of the 2007 attainment year inventory during the maintenance period, even without implementation of CAIR. (See also discussion below.) As shown in Table 9, VOC and NOXemissions in the

      Manitowoc County area are projected to decrease by 0.99 tpd and 3.88 tpd, respectively, between 2007 and 2020. As shown in Table 10, VOC and

      NOXemissions in the Door County area are projected to decrease by 2.96 tpd and 1.27 tpd, respectively, between 2007 and 2020.

      In addition, as shown in Table 11, VOC and NOXemissions in the upwind areas of Sheboygan and Milwaukee-Racine are projected to decrease by 16.20 tpd and 66.63 tpd, respectively, between 2007 and 2020.

      In addition, LADCO performed a regional modeling analysis to address the effect of the recent court decision vacating CAIR. This analysis is documented in LADCO's ``Regional Air Quality Analyses for

      Ozone, PM2.5, and Regional Haze: Final Technical Support Document

      (Supplement), September 12, 2008.'' LADCO produced a base year inventory for 2005 and future year inventories for 2009, 2012, and 2018. To estimate future EGU NOXemissions without implementation of CAIR, LADCO projected 2007 EGU NOX emissions for all States in the modeling domain based on Energy

      Information Administration growth rates by State (North American

      Electric Reliability Corporation (NERC) region) and fuel type for the years 2009, 2012 and 2018. The assumed 2007-2018 growth rates were 8.8% for Illinois, Iowa, Missouri and Wisconsin; 13.5% for Indiana,

      Kentucky, Michigan and Ohio; and 15.1% for Minnesota. Emissions were adjusted by applying legally enforceable controls, e.g., consent decree or rule. EGU NOXemissions projections for the States of

      Illinois, Indiana, Michigan, Ohio, and Wisconsin are shown below in

      Table 12. The emission projections used for the modeling analysis do not account for certain relevant factors such as allowance trading and potential changes in operation of existing control devices. The

      NOXprojections indicate that, due to the NOXSIP

      Call, certain State rules, consent decrees resulting from enforcement cases, and ongoing implementation of a number of mobile source rules,

      EGU NOXis not expected to increase in Wisconsin, or any of the States in the immediate region, and overall NOX emissions in Wisconsin, and the nearby region are expected to decrease substantially between 2005 and 2020.\2\ Total NOXemissions projections are shown in Table 13, below.

      \2\ There is more uncertainty about the use of SO2 allowances and future projections for SO2emissions; thus, further review and discussion will be needed regarding the appropriateness of using these emission projections for future

      PM2.5SIP approvals and redesignation requests.

      Given that 2007 is one of the years Wisconsin used to demonstrate monitored attainment of the 8-hour NAAQS, Table 12 shows that EGU

      NOXemissions will remain below attainment levels through 2018. If the rate of emissions increase between 2012 and 2018 continues through 2020, EGU NOXemissions would still remain below attainment levels in 2020. Furthermore, as shown in Table 13, total

      NOXemissions clearly continue to decrease substantially throughout the maintenance period.

      Ozone modeling performed by LADCO supports the conclusion that the

      Manitowoc County and Door County areas will maintain the standard throughout the maintenance period. Peak modeled ozone levels in the

      Manitowoc County area for 2009, 2012 and 2018 are 0.081 ppm, 0.079 ppm, and 0.073 ppm, respectively. Peak modeled ozone levels in the Door

      County area for 2009, 2012 and 2018 are 0.084 ppm, 0.081 ppm, and 0.076 ppm, respectively. These projected ozone levels were modeled applying only legally enforceable controls; e.g., consent decrees, rules, the

      NOXSIP Call, Federal motor vehicle control programs, etc.

      Because these programs will remain in place, emission levels, and therefore ozone levels, would not be expected to increase significantly between 2018 and 2020. Given that projected emissions and modeled ozone levels continue to decrease substantially through 2018, it is reasonable to infer that a 2020 modeling run would also show levels well below the 1997 8-hour ozone standard.

      EPA has considered the relationship of the maintenance plans to the reductions required pursuant to CAIR. This rule was remanded to EPA, and the process of developing a replacement rule is ongoing. However, the remand of CAIR does not alter the requirements of the

      NOXSIP Call, and Wisconsin has demonstrated maintenance without any additional CAIR requirements (beyond those required by the

      NOXSIP Call). Therefore, EPA believes that Wisconsin's demonstration of maintenance under sections 175A and 107(d)(3)(E) is valid.

      The NOXSIP Call requires States to make significant, specific emissions reductions. It also provided a mechanism, the

      NOXBudget Trading Program, which States could use to achieve those reductions. When EPA promulgated CAIR, it discontinued

      (starting in 2009) the NOXBudget Trading Program, 40 CFR 51.121(r), but created another mechanism, the CAIR ozone season trading program, which States could use to meet their SIP Call obligations (70

      FR 25289-25290). EPA notes that a number of States, when submitting SIP revisions to require sources to participate in the CAIR ozone season trading program, removed the SIP provisions that required sources to participate in the NOXBudget Trading Program. In addition, because the provisions of CAIR, including the ozone season

      NOXtrading program, remain in place during the remand, EPA is not currently administering the NOXBudget Trading

      Program. Nonetheless, all States, regardless of the current status of their regulations that previously required participation in the

      NOXBudget Trading Program, will remain subject to all of the requirements in the NOXSIP Call even if the existing

      CAIR ozone season trading program is withdrawn or altered. In addition, the anti-backsliding provisions of 40 CFR 51.905(f) specifically provide that the provisions of the NOXSIP Call, including the statewide NOXemission budgets, continue to apply after revocation of the 1-hour standard.

      All NOXSIP Call States have SIPs that currently satisfy their obligations under the SIP Call, the SIP Call reduction requirements are being met, and EPA will continue to enforce the requirements of the NOXSIP Call even after any response to the CAIR remand. For these reasons, EPA believes that regardless of the status of the CAIR program, the NOXSIP Call requirements can be relied upon in demonstrating maintenance. d. Monitoring Network

      Wisconsin currently operates one ozone monitor in Manitowoc County and one ozone monitor in Door County. Wisconsin has committed to continue to operate and maintain an approved ozone monitoring network in the Manitowoc County and Door County areas. WDNR has also committed to consult with EPA regarding any changes in siting that may become necessary in the future. Wisconsin remains obligated to continue to quality assure monitoring data in accordance with 40 CFR part 58 and enter all data into the AQS in accordance with Federal guidelines. e. Verification of Continued Attainment

      Continued attainment of the ozone NAAQS in the Manitowoc County and

      Door County areas depends, in part, on the State's efforts toward tracking indicators of continued attainment during the maintenance period. Wisconsin's plan for verifying continued attainment of the 8- hour standard in the Manitowoc County and Door County areas consists of continued ambient ozone monitoring in accordance with the requirements of 40 CFR part 58. WDNR will also continue to develop and submit periodic emission inventories as required by the Federal Consolidated

      Emissions Reporting Rule (67 FR 39602, June 10, 2002), and will evaluate future VOC and NOXemissions inventories for increases over the 2007 emission inventory levels. f. Contingency Plan

      The contingency plan provisions are designed to promptly correct or prevent a violation of the NAAQS that might occur after redesignation of an area to attainment. Section 175A of the CAA requires that a maintenance plan include such contingency measures as EPA deems necessary to assure that the State will promptly correct a violation of the NAAQS that occurs after

      Page 22061

      redesignation. The maintenance plan should identify the contingency measures to be adopted, a schedule and procedure for adoption and implementation of the contingency measures, and a time limit for action by the State. The State should also identify specific indicators to be used to determine when the contingency measures need to be adopted and implemented. The maintenance plan must include a requirement that the

      State will implement all measures with respect to control of the pollutant(s) that were contained in the SIP before redesignation of the area to attainment. See section 175A(d) of the CAA.

      As required by section 175A of the CAA, Wisconsin has adopted contingency plans for the Manitowoc County and Door County areas to address possible future ozone air quality problems. A contingency plan response will be triggered whenever a three-year average fourth-high monitored value of 0.085 ppm or greater is monitored within the maintenance area. When a response is triggered, WDNR will evaluate existing but not fully implemented, on-the way, and, if necessary, new control measures to correct the violation of the standard within 18 months. The State has confirmed EPA's interpretation that this commitment means that the measure will be adopted and implemented within 18 months of the triggering event. In addition, it is EPA's understanding that to acceptably address a violation of the standard, existing and on-the way control measures must be in excess of emissions reductions included in the projected maintenance inventories.

      WDNR included the following list of potential contingency measures in its maintenance plans: i. Broaden the application of the NOXRACT program by including a larger geographic area, and/or including sources with potential emissions of 50 tons per year, and/or increasing the cost- effectiveness thresholds utilized as a basis for Wisconsin's

      NOXRACT Program; ii. Develop an anti-idling control program for mobile sources targeting diesel vehicles; iii. Adopt a rule reducing VOC content in architectural, industrial and maintenance coatings; and iv. Adopt a rule reducing VOC content in commercial and consumer products. g. Provisions for Future Updates of the Ozone Maintenance Plan

      As required by section 175A(b) of the CAA, WDNR commits to submit to the EPA updated ozone maintenance plans eight years after redesignation of the Manitowoc County and Door County areas to cover an additional ten-year period beyond the initial ten-year maintenance period. As required by section 175A of the CAA, Wisconsin has committed to retain the VOC and NOXcontrol measures contained in the

      SIP prior to redesignation.

      EPA has concluded that the maintenance plans adequately address the five basic components of a maintenance plan: Attainment inventory, maintenance demonstration, monitoring network, verification of continued attainment, and a contingency plan. Thus EPA proposes to find that the maintenance plan SIP revisions submitted by Wisconsin for the

      Manitowoc County and Door County areas meet the requirements of section 175A of the CAA.

   2. Adequacy of Wisconsin's MVEBs 1. How are MVEBs developed and what are the MVEBs for the Manitowoc

      County and Door County areas?

      Under the CAA, States are required to submit, at various times, control strategy SIP revisions and ozone maintenance plans for ozone nonattainment areas and for areas seeking redesignations to attainment of the ozone standard. These emission control strategy SIP revisions

      (e.g., RFP and attainment demonstration SIP revisions) and ozone maintenance plans create MVEBs based on onroad mobile source emissions for criteria pollutants and/or their precursors to address pollution from onroad transportation sources. The MVEBs are the portions of the total allowable emissions that are allocated to highway and transit vehicle use that, together with emissions from other sources in the area, will provide for attainment or maintenance.

      Under 40 CFR part 93, a MVEB for an area seeking a redesignation to attainment is established for the last year of the maintenance plan.

      The MVEB serves as a ceiling on emissions from an area's planned transportation system. The MVEB concept is further explained in the preamble to the November 24, 1993, transportation conformity rule (58

      FR 62188).

      Under section 176(c) of the CAA, new transportation projects that receive Federal funding or support, such as the construction of new highways, must ``conform'' to (i.e., be consistent with) the SIP.

      Conformity to the SIP means that transportation activities will not cause new air quality violations, worsen existing air quality violations, or delay timely attainment of the NAAQS. If a transportation plan does not conform, most new transportation projects that would expand the capacity of roadways cannot go forward.

      Regulations at 40 CFR part 93 set forth EPA policy, criteria, and procedures for demonstrating and assuring conformity of such transportation activities to a SIP.

      When reviewing SIP revisions containing MVEBs, including attainment strategies, rate-of-progress plans, and maintenance plans, EPA must affirmatively approve or find that the MVEBs are ``adequate'' for use in determining transportation conformity before the MVEBs can be used.

      Once EPA affirmatively approves or finds the submitted MVEBs to be adequate for transportation conformity purposes, the MVEBs must be used by State and Federal agencies in determining whether proposed transportation projects conform to the SIP as required by section 176(c) of the CAA. EPA's substantive criteria for determining the adequacy of MVEBs are set out in 40 CFR 93.118(e)(4).

      EPA's process for determining adequacy of a MVEB consists of three basic steps: (1) Providing public notification of a SIP submission; (2) providing the public the opportunity to comment on the MVEB during a public comment period; and, (3) EPA taking action on the MVEB. The process for determining the adequacy of submitted SIP MVEBs is codified at 40 CFR 93.118.

      The maintenance plans submitted by Wisconsin for the Manitowoc

      County and Door County areas contain new VOC and NOXMVEBs for the areas for the years 2012 and 2020. The availability of the SIP submission with these 2012 and 2020 MVEBs was announced for public comment on EPA's Adequacy Web site on February 24, 2010, at: http:// www.epa.gov/otaq/stateresources/transconf/currsips.htm. The EPA public comment period on adequacy of the 2012 and 2020 MVEBs for the Manitowoc

      County and Door County areas closed on March 26, 2010. No adverse comments on the submittal were received during the adequacy comment period.

      EPA, through this rulemaking, has found adequate and is proposing to approve the MVEBs for use to determine transportation conformity in the Manitowoc County and Door County areas, because EPA has determined that the areas can maintain attainment of the 8-hour ozone NAAQS for the relevant maintenance period with mobile source emissions at the levels of the MVEBs. WDNR has determined the 2012 MVEBs for the

      Manitowoc County and Door County areas to be 1.76 tpd for VOC and 3.76 tpd for NOX, and 0.78 tpd for VOC

      Page 22062

      and 1.55 tpd for NOX, respectively. WDNR has determined the 2020 MVEBs for the Manitowoc County and Door County areas to be 1.25 tpd for VOC and 1.86 tpd for NOX, and 0.53 tpd for VOC and 0.74 tpd for NOX, respectively. These MVEBs are consistent with the onroad mobile source VOC and NOXemissions projected by the Wisconsin Department of Transportation for 2012 and 2020, as summarized in Tables 9 and 10 above. Wisconsin has demonstrated that the Manitowoc County area can maintain the 8-hour ozone NAAQS with mobile source emissions of 1.76 tpd and 1.25 tpd of

      VOC and 3.76 tpd and 1.86 tpd of NOXin 2012 and 2020, respectively, since emissions will remain under attainment year emission levels. Wisconsin has demonstrated that the Door County area can maintain the 8-hour ozone NAAQS with mobile source emissions of 0.78 tpd and 0.53 tpd of VOC and 1.55 tpd and 0.74 tpd of

      NOXin 2012 and 2020, respectively, since emissions will remain under attainment year emission levels.

   3. 2005 Base Year Emissions Inventories

      As discussed above, section 172(c)(3) of the CAA requires areas to submit a base year emissions inventory. On June 12, 2007, WDNR submitted a 2005 base year emissions inventory to meet this requirement. Emissions contained in the submittal cover the general source categories of point sources, area sources, on-road mobile sources, and non-road mobile sources. All emission summaries were accompanied by descriptions of emission calculation procedures and sources of input data.

      Point source sector emissions inventories were developed using reported point source emissions, EPA's Clean Air Markets database and approved EPA techniques for emissions calculations. Emissions were estimated by collecting process-level information from each facility that qualifies for inclusion into WDNR's point source database.

      Process, boiler, fugitive and tank emissions were typically calculated using throughput information multiplied by an emission factor for the process. Emission factor sources included mass balance, stack testing, continuous emissions monitors, engineering judgment and EPA's Factor

      Information Retrieval database.

      Area source emissions were calculated using population, gasoline consumption, employment, crop acreages, and other activity surrogates.

      The results of an EPA Solvent Mass Balance study were used to estimate emissions for some categories. Emission factors were derived from local data, local or national surveys and EPA guidance for the development of emissions inventories. Point source emissions were subtracted from total category specific area source emissions to prevent double counting.

      Nonroad mobile source emissions were calculated using EPA's NMIM and emissions estimates developed for commercial marine vessels, aircraft, and railroads (MAR), three nonroad categories not included in

      NMIM. Before NMIM was run, the following modifications and additions were made to the NMIM input data: (1) Revised activity data for construction equipment using updates provided by Pechan; (2) revised allocation data for recreational marine equipment using updates provided by ENVIRON International Corporation (ENVIRON); (3) added emission factors for diesel tampers/rammers provided by Pechan; (4) revised population data for construction and recreational marine equipment using updates provided by Pechan and ENVIRON, respectively;

      (5) revised growth rates using updates provided by Pechan; and (6) revised gasoline parameters, including Reid Vapor Pressure, oxygenate content and sulfur content, using updates provided by the States and

      Pechan. Onroad mobile source emissions were calculated using the

      MOBILE6.2 emissions model.

      The 2005 summer day emissions of VOC and NOXfor the

      Manitowoc County and Door County areas are summarized in Table 14, below. EPA is proposing to approve these 2005 base year inventories as meeting the section 172(c)(3) emissions inventory requirement.

      GRAPHIC

      TIFF OMITTED TP27AP10.006

7. What actions is EPA taking?

   EPA is proposing to determine that the Manitowoc County and Door

   County areas have attained the 1997 8-hour ozone NAAQS. EPA is proposing to approve the redesignations of the Manitowoc County and

   Door County areas from nonattainment to attainment for the 1997 8-hour ozone NAAQS. After evaluating the redesignation requests submitted by

   Wisconsin, EPA believes that the requests meet the redesignation criteria set forth in section 107(d)(3)(E) of the CAA. The final approval of these redesignation requests would change the official designations for the Manitowoc County and Door County areas from nonattainment to attainment for the 1997 8-hour ozone standard. EPA is also proposing to approve the maintenance plan SIP revisions for the

   Manitowoc County and Door County areas. EPA's proposed approvals of the maintenance plans is based on the State's demonstration that the plans meet the requirements of section 175A of the CAA, as described more fully above. EPA is proposing to approve WDNR's 2005 base year emissions inventories for the Manitowoc County and Door County areas as meeting the requirements of section 172(c)(3) of the CAA. Finally, EPA finds adequate and is proposing to approve Wisconsin's 2012 and 2020

   MVEBs for the Manitowoc County and Door County areas.

8. Statutory and Executive Order Reviews

   Under the CAA, redesignation of an area to attainment and the accompanying approval of a maintenance plan under section 107(d)(3)(E) are actions that affect the status of a geographical area and do not impose any additional regulatory requirements on sources beyond those imposed by State law. A redesignation to attainment does not in and of itself create any new requirements, but rather results in the applicability of requirements contained in the CAA for areas that have been redesignated to attainment. Moreover, the Administrator is required to approve a SIP submission that complies with the provisions of the

   Page 22063

   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, these actions merely do not impose additional requirements beyond those imposed by State law and the Clean Air Act.

   For that reason, these actions:

   Are not ``significant regulatory actions'' subject to review by the Office of Management and Budget under Executive Order 12866 (58 FR 51735, October 4, 1993);

   Do not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);

   Are 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.);

   Do 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);

   Do not have Federalism implications as specified in

   Executive Order 13132 (64 FR 43255, August 10, 1999);

   Are 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);

   Are 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

   Do 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.
