Technical Support Document
Proposed Rulemaking Action on the
San Joaquin Valley 2007 Ozone Plan and Related Portions of the Revised 2007 State Strategy

      This document provides supporting information and analysis for EPA's proposed rulemaking action on the San Joaquin Valley Air Pollution Control District's 2007 Ozone Plan (adopted April 30, 2007, revised December 18, 2008 and July 21, 2011) and the related portions of the California Air Resources Board's State Strategy for California's 2007 State Implementation Plan (adopted with amendments on September 27, 2007 and revised and updated on April 24, 2009 and July 21, 2011). It describes the Clean Air Act requirements for 8-hour ozone plans and EPA's regulations and policies interpreting these requirements. It also describes the elements of the SJV 2007 Ozone Plan and 2007 State Strategy that address these requirements and EPA's evaluation of whether the State's submittals meet these requirements.

A.  The 1997 8-hour Ozone National Ambient Air Quality Standards 
1.  The 1997 8-Hour Ozone National Ambient Air Quality Standards
a.  Level and Form of the Standard
      On July 18, 1997, EPA revised the primary and secondary national ambient air quality standards (NAAQS) for ozone to replace the then-current 1-hour ozone standard of 0.12 parts per million (ppm) with an 8-hour standards set at a stricter level of 0.08 parts per million (ppm). 62 FR 38856.[,] The 8 - hour standards are met at an ambient air quality monitoring site 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. 40 CFR § 50.10(b). 
      Ground-level ozone pollution is formed by the reaction of volatile organic compounds (VOC) and nitrogen oxides (NOx) in the atmosphere in the presence of sunlight. These two pollutants, often referred to as ozone precursors, are emitted by many types of pollution sources, including on-road and off-road motor vehicles and engines (e.g., cars, trucks, construction equipment and locomotives), power plants and industrial facilities, and smaller area sources (e.g., paints, lawn and garden equipment, and open burning) .

b.  Health Effects
      Ozone is a significant health concern, particularly for children and people with asthma and other respiratory diseases. Ozone has also been associated with increased hospitalizations and emergency room visits for respiratory causes, school absences, and reduced activity and productivity as a consequence of ozone-related respiratory symptoms.
      Breathing ozone can trigger a variety of health problems. Ozone can irritate the respiratory system, causing coughing, throat irritation, an uncomfortable sensation in the chest, and/or pain when breathing deeply. Ozone can worsen asthma and possibly other respiratory diseases, such as bronchitis and emphysema. When ozone levels are high, more people with asthma have attacks that require a doctor's attention or the use of additional medication. Ozone can reduce lung function and make it more difficult to breathe deeply, and breathing may become more rapid and shallow than normal, thereby limiting a person's normal activity. In addition, breathing ozone can inflame and damage the lining of the lungs, which may lead to permanent changes in lung tissue, irreversible reductions in lung function, and a lower quality of life if the inflammation occurs repeatedly over a long time period. People who are particularly susceptible to the effects of ozone include children, adults who are active outdoors, people with respiratory disease (such as asthma), and people with unusual sensitivity to ozone. 62 FR 33856, 33859.
      More detailed information on the health effects of ozone as well as information on the welfare effects ozone can be found at the following Web site: http://www.epa.gov/ttn/ naaqs/standards/ozone/s_o3_index.html.

2.  Implementing the 8-Hour Ozone NAAQS
a.  Designations
      The process for designating areas as either attainment or nonattainment following promulgation of a new or revised NAAQS is found in CAA section 107(d). Under this section, each state governor or tribal leader has an opportunity to recommend to EPA air quality designations, including the appropriate boundaries for areas. Under CAA section 107, state and tribal recommendations are due within one year of promulgation of a new or revised NAAQS. EPA then has one to two additional years to promulgate final designations. By no later than 120 days prior to promulgating designations, EPA is required to notify states or tribes of any intended modifications to their recommended areas and boundaries. States and tribes then have an opportunity to provide a demonstration as to why the modifications indicated by EPA are inappropriate. CAA section 107(d)(1)(B)(ii). Whether or not a state or tribe provides a recommendation, EPA must promulgate the designation that it deems appropriate.
      For the 1997 8-hour ozone standard, the Transportation Equity Act for the Twenty-first Century (TEA - 21) revised the deadline to promulgate nonattainment designations to provide an additional year (to July 2000). Additional Congressional action restricted EPA's authority to spend money to designate areas until earlier of June 2001 or the date of the Supreme Court ruling in the litigation challenging the 1997 ozone NAAQS.
      In June 2000, we asked each state and tribal Governor or tribal leader to submit their designation recommendations (including boundary recommendations) and supporting documentation to EPA. Because of the uncertainties due to the ongoing litigation on the 8-hour ozone standard, we did not notify states and tribes of any intended modifications and did not designate areas at that time. After the legal challenges to the 1997 ozone NAAQS were resolved in 2001, we requested that states and tribes provide updated recommendations, based on ambient air quality data for the years 2000 to 2002 and any additional supporting documentation by July 15, 2003. 
      On June 15, 2003, California submitted its recommendations, including the recommendation that the SJV air basin be designated as nonattainment for the 1997 8-hour ozone standard. On September 8, 2003, EPA published a Notice of Availability (NOA) announcing the availability of the state and tribal recommendations. See 68 FR 52933. 
      On December 3, 2003, we notified California via letter of our intent to accept its recommendation for designating the San Joaquin Valley air basin as nonattainment. EPA, however, proposed to expand the boundaries of the SJV nonattainment area to include the mountain counties of Amador, Calaveras, Tuolumne, and Mariposa. On December 10, 2003, we published a NOA announcing the availability of our letters to California and other states that described our intended modifications to their recommendations. See 68 FR 68805. In our letters, we asked states to submit, by no later than February 6, 2004, a demonstration as to why our modifications were not appropriate.
      On February 4, 2004, California responded to our proposed modification to its recommendations on boundaries for the SJV nonattainment area, requesting that we exclude the four mountain counties from the SJV nonattainment area. On April 15, 2004, we designated the SJV air basin, excluding the four mountain counties, as nonattainment for the 1997 8-hour ozone standard and classified the area as "serious" under CAA section 181(a)(1) and 40 CFR § 51.903(a), Table 1. See 69 FR 23858 at 23888-89 (April 30, 2004). The designation, which became effective on June 15, 2004, is codified at 40 CFR § 81.305.
      The designation of an area as nonattainment starts the process whereby a state develops an implementation plan that includes, among other things, a demonstration showing how the area will attain the NAAQS by the attainment dates prescribed in the CAA. Under CAA section 182 for ozone nonattainment areas and EPA's regulations implementing the 1997 ozone NAAQS (see 40 CFR part 51, subpart X), states had until June 15, 2007 - three years after final designations to nonattainment - to submit to EPA their SIPs demonstrating RFP and attainment. 40 CFR §§ 51.910(a)(1)(ii)(B) and 51.908(a).

b.  California's Request for Reclassification of the San Joaquin Valley 1997 8-hour Ozone Nonattainment Area. 
As part of California's submittal for the San Joaquin Valley 1997 8-hour ozone nonattainment area, the State requested that EPA reclassify the area from "serious" to "extreme" nonattainment for the 1997 8-hour ozone standard under section 181(b)(3) of the CAA. 
CAA section 181(b)(3) states: "The Administrator shall grant the request of any State to reclassify a nonattainment area in that State in accordance with Table 1 of subsection (a) of this section to a higher classification. The Administrator shall publish a notice in the Federal Register of any such request and of action by the Administrator granting the request." This provision for voluntary reclassification has been brought forward as part of the transition from the 1-hour ozone standard to the 1997 8-hour ozone standard. See 40 CFR 51.903(b) ("A State may request a higher classification for any reason in accordance with section 181(b)(3) of the CAA") and 40 CFR 51.903(a), Table 1.
We granted California's request on May 5, 2010 and reclassified the San Joaquin Valley to extreme nonattainment for the 1997 8-hour ozone standard,  effective June 4, 2010. See 75 FR 24409. Because the SJV 2007 Ozone Plan was developed to address the CAA's extreme area planning requirements, California was not required to make additional SIP submittals in response to this reclassification.

c. 1997 8-hour Ozone Standard Planning Requirements
In order to assist states in developing effective plans to address their ozone nonattainment problem, EPA issued a rule for implementing the 1997 8-hour ozone standard, also known as the ozone implementation rule. We issued this rule in accordance with the statutory requirements of the CAA as set forth in subparts 1 and 2 of Part D of Title 1, i.e., sections 171 - 179B, 181 and 182. 
The rule was proposed on June 2, 2003 (68 FR 32802) and finalized in two phases. The Phase 1 rule addresses classifications for the 1997 8-hour ozone standard; revocation of the 1-hour ozone standard; anti-backsliding principles for 1-hour ozone requirements; attainment dates; and the timing of emissions reductions needed for attainment. See 69 FR 23951 (April 30, 2004).  The Phase II rule addresses, among other things, the requirements for reasonably available control technology and measures (RACT and RACM), reasonable further progress (RFP), modeling and attainment demonstrations, and new source review. See 70 FR 71612 (November 29, 2005). The rule is codified at 40 CFR part 51, subpart X. 
      The ozone implementation rule covers most CAA requirements for 1997 8-hour ozone state implementation plans. EPA has issued other documents that provide additional guidance on these CAA requirements. We will provide references to these documents as appropriate.

B.  Ozone Air Quality in the San Joaquin Valley
      The San Joaquin Valley ozone nonattainment area is located in the southern part of California's Central Valley. It is home to almost 4 million people and is the nation's leading agricultural area. Stretching over 250 miles from north to south and averaging 80 miles wide, it is partially enclosed by the Coast Mountain range to the west, the Tehachapi Mountains to the south, and the Sierra Nevada range to the east. In total, the SJV ozone nonattainment area encompasses over 23,000 square miles and includes all or part of eight counties: San Joaquin, Stanislaus, Merced, Madera, Fresno, Tulare, Kings, and the valley portion of Kern. See Figure IB-2. The local air district is the San Joaquin Valley [Unified] Air Pollution Control District (SJV[U]APCD or District).
      Ozone levels in the San Joaquin Valley are the highest along the eastern side of the Valley from just north of Fresno to south of Bakersfield. Since 2000, the SJV has seen a generally steady decline in ozone levels and days over the standard.  See Figure I-1 and Table I-1.

D.  Public Notice and Hearing Requirements for and Completeness of SIP Submittals
1.  Public Notice and Hearing Requirements for SIP Submittals
      CAA sections 110(a) and (l) require a state to provide reasonable public notice and hearing prior to the adoption and submittal of a SIP or SIP revision. To meet this requirement, every SIP submittal should include evidence that adequate public notice was given and a public hearing was held consistent with EPA's implementing regulations in 40 CFR § 51.102.
      Both the SJVUAPCD and CARB have satisfied applicable statutory and regulatory requirements for reasonable public notice and hearing prior to adoption and submittal of the 2007 Ozone Plan. The District conducted public workshops, provided public comment periods, and held a public hearing prior to the adoption of the Plan on April 30, 2007. See SJVUAPCD Governing Board Resolution, 07-04-11a, April 30, 2007page 3. CARB also provide the required public notice and opportunity for public comment prior to its June 14, 2007 public hearing on the Plan. See CARB, Notice of Public Meeting to Consider the Approval of the San Joaquin Valley 2007 Ozone Plan," May 15, 2007. The District also provided the required public notice and hearing on the 2008 revision to the Plan. See SJVAPCD Governing Board Resolution No. 08-12-18, December 18, 2008, p. 2.
      CARB also conducted public workshops, provided public comment periods, and held a public hearing prior to its adoption of the 2007 State Strategy on September 27, 2007. See CARB, Notice of Public Meeting to Consider Approval of the Proposed State Strategy for California's State Implementation Plan (SIP) for the Federal 8-Hour Ozone and PM2.5 Standards, May 7, 2007 and CARB Resolution No. 07-28, September 27, 2007. CARB also provide the required public notice, opportunity for public comment, and public hearing prior to its April 24, 2009 adoption of revisions to the Strategy and its July 21, 2011 adoption of the 2011 Ozone SIP Revisions.
      Each of the five SIP submittals that comprise the SJV 2007 8-hour ozone SIP includes proof of publication for notices of SJVAPCD and CARB public hearings as evidence that all hearings were properly noticed.

2.  Completeness Determinations on SIP Submittals
      CAA section 110(k)(1)(B) requires EPA to determine whether a SIP submittal is complete within 60 days of receipt. This section also provides that any plan that we have not affirmatively determined to be complete or incomplete will be deemed complete six months after the day of submittal by operation of law. A completeness review allows us to determine if the submittal includes all the necessary items and information we need to act on it.
      We make completeness determinations using criteria in 40 CFR part 51, Appendix V. These criteria fall into two categories:  administrative information and technical support information. The administrative information provides documentation that the state has followed basic administrative procedures during the SIP-adoption process and thus we have a legally-adopted SIP revision in front of us. The technical support information provides us the information we need to determine the impact of the proposed revision on attainment and maintenance of the air quality standards.
      We notify a state of our completeness determination by letter unless the submittal became complete by operation of law. A finding of completeness does not approve the submittal as part of the SIP nor does it indicate that the submittal is approvable. It does start the 12 month clock we have to act on the SIP submittal. See CAA section 110(k)(2).
      The November 16, 2007 submittal of the 2007 Ozone Plan and the April 24, 2009 submittal of amendments to that Plan went complete by operation of law on May 16, 2009 and October 24, 2009, respectively. The November 16, 2007 submittal of the 2007 State Strategy and the August 12, 2009 submittal of the 2009 revisions to the Strategy went complete by operation of law on May 16, 2008 and February 12, 2010, respectively.
      We found the 2011 Ozone SIP Revisions complete on August 23, 2011. See letter, Deborah Jordan, EPA Region 9 to James Goldstene, CARB, August 23, 2011.
      
                                       
                                       
                                       
                                       
                                       
                                       
                                       
                                       
        II. Evaluation of the San Joaquin Valley 2007 8-Hour Ozone SIP
   

A.  Emissions Inventories
1.  Requirements for Emissions Inventories
      CAA section 182(a)(1) requires each state with an ozone nonattainment area classified as marginal or above to submit, within two years of the area's designation as nonattainment, a "comprehensive, accurate, current inventory of actual emissions from all sources" of the relevant pollutant or pollutants in accordance with guidance provided by EPA. To implement this section, the 8-hour ozone implementation rule requires a state to submit an emissions inventory meeting the requirements of CAA section 182(a)(1) for each of its subpart 2 8-hour ozone nonattainment areas by June 15, 2006 (for those areas designated nonattainment effective June 15, 2004). See 40 CFR § 51.915. These inventories should meet the ozone-relevant data requirements of EPA's Consolidated Emissions Reporting Rule (CERR, codified at 40 CFR part 51 subpart A). Id. The inventories should also meet all other applicable EPA guidance.
      EPA has issued the "Emissions Inventory Guidance for Implementation of Ozone and Particulate Matter National Ambient Air Quality Standards (NAAQS) and Regional Haze Regulations," EPA - 454/R - 05 - 001, November 2005 ("EI Guidance"). EPA developed the EI Guidance to complement the CERR and to provide specific guidance on how to develop base year and future year baseline emissions inventories for 8-hour ozone, PM2.5, and regional haze SIPs. 
      For areas that were initially designated nonattainment for the 8-hour ozone standard in 2004, EPA recommends using calendar year 2002 as the base year for the inventory required by CAA section 182(a)(1). EI Guidance, p. 8.
      Emissions inventories for ozone should include emissions of VOC, NOx, and carbon monoxide (CO) and represent an average summer week day during the ozone season. EI Guidance, pp. 14 and 17. States should include documentation in their submittals explaining how the emissions data were calculated. 70 FR at 71664 and EI Guidance, p. 40. In estimating mobile source emissions, states should use the latest emissions models and planning assumptions available at the time the SIP is developed. 68 FR at 32854 and 70 FR 71666. For California, the latest emissions model is the most recently EPA-approved version of EMFAC, EMFAC2007. See 68 FR 3464 (January 18, 2008).
      The emissions inventory required under the 8-hour ozone implementation rule is a SIP provision that must be approved by EPA under CAA section 110(k) and is subject to the public hearing requirements of sections 110(a)(2) and (l). For areas classified under subpart 2, the emissions inventory submittal is due one year before the attainment and/or RFP Plan. Applicable EPA policy allows a state to defer the public hearing on its inventory until the time it adopts its attainment and/or RFP plan. 70 FR at 71664 and memorandum, John Calcagni and William Laxton, OAQPS-EPA, "Public Hearing Requirements for 1990 Base-Year Emissions Inventories for Ozone and Carbon Monoxide Nonattainment Areas," September 29, 1992.
      In addition to the base year inventory, states must also develop specific baseline inventories as part of the reasonable further progress demonstration required by CAA sections 182(b)(1) and 182(c)(2)(B). The requirements for RFP baseline inventories will be discussed in section II.G. of this TSD.

2.  Emissions Inventories in the SJV 8-Hour Ozone SIP
Note: We discuss the CARB's statewide inventory to provide background to our evaluation of the emissions inventories in the SJV 2007 Ozone Plan. We are not proposing any SIP action on the statewide inventory here, only on the SJV inventory.
      CARB submitted statewide inventories for the ozone precursors, NOx and VOC, as part of the 2007 State Strategy. See Appendix A for the emissions inventory output tables and Appendix F for documentation of the emissions inventory. Summer planning inventories are provided for the base year of 2002 and baseline years of 2005, 2006, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2017, 2018, 2020, and 2023. These statewide emissions inventories are assembled and maintained by CARB in the California Emissions Inventory Development and Reporting System (CEIDARS) and the California Emission Forecasting and Planning Inventory System (CEFS) databases. Both systems are described in Appendix F. In 2004, CARB submitted the 2002 base year inventory including all necessary data elements to EPA as required by the CERR.
      The inventories in Appendix A are summer season planning inventories on which the 2007 State Strategy is based. Inventories for future years (also known as baseline inventories) incorporate reductions from control measures adopted prior to December 2006 and are projected from the 2002 base year inventory. 2007 State Strategy, Appendix A, p. 1. Specific adjustments for State and District rules adopted in the 2004 to 2006 time period, as well as adjustments to among other things, heavy duty truck VMT in 2005 and pesticide emissions, are described in the introductory section to Appendix A and can also be found in Appendix B to the SJV 2007 Ozone SIP.
      The base year and future baseline planning inventories for NOx and VOC for the SJV ozone nonattainment area together with additional documentation for the inventories are found in Appendix B of the SJV 2007 Ozone Plan. Summer average day (May through October) are provided for the base year 2002,  2005 (which was included for control measure development), and the RFP years of 2008, 2011, 2014, 2017, and 2020. Inventories are also provided for 2012 (the attainment year for serious areas, SJV initial classification) 2018 (the attainment date for severe areas), and 2023 (the attainment year for extreme areas, SJV's current classification). On-road motor vehicle emissions are estimated using EMFAC2007. 2007 Ozone Plan, p. B-1. The inventories in 2007 Ozone Plan, Appendix B are consistent with the inventories in the 2007 State Strategy, Appendix A.
      All inventories include emissions from point, area, on-road, and non-road sources. None of the inventories cited above specifically shows emissions of CO or emissions from non-anthropogenic sources (that is, biogenic or natural sources) although inventories developed for input into the air quality modeling do include CO emissions and non-anthropogenic sources.

Additional Revisions to the Plan's Base Year and Projected Baseline Inventories
      As part of its 2011 Ozone SIP Revisions, CARB submitted revised base year and future year baseline inventories. These revisions were the result of several factors include revised inventorying methodologies, better activity and usage data, the reductions from measures adopted since 2007, and changes to economic forecasts for certain source categories in 2008 and later years.
      CARB made technical changes to the inventory for diesel trucks and buses as part of its December 2010 rulemaking amending its In-Use On-Road Truck and Bus Rule. These included updates and revisions to:
   * regional allocation factors
   * out-of-state vehicle miles traveled estimates
   * new vehicle inventory categories
   * lifetime mileage assumptions
See CARB, Staff Report: Initial State of Reasons for Proposed Rulemaking, Proposed Amendments to the Truck and Bus Regulations, The Drayage Truck Regulation and the Tractor-Trailer Greenhouse Gas Regulation, October 2010, p. 17.
      CARB also comprehensively updated and revised the inventory for certain categories of off-road equipment as part its December 2010 rulemaking amending the In-Use Off-Road Equipment Rule. These included updates and revisions to:
  * equipment population
  * hours of use
  * load factors
  *      future equipment sales and activity
See CARB, Staff Report: Initial State of Reasons for Proposed Rulemaking, Proposed Amendments to the Regulation for In-Use Off-Road Diesel-Fueled Fleets and the Off-Road Large Spark-Ignition Fleet Requirements, October 2010, pp. 16-17.
      SJVAPCD has also made revisions to the base year and baseline inventories since submittal of the 2007 Ozone Plan. These revisions include developing a new methodology for estimating NOx emissions from industrial equipment for which natural gas consumption or emissions are not reported for individual sources. The initial emissions estimates for these "unspecified" manufacturing and industrial natural gas consumption sources in the 2007 Ozone Plan came from an estimate developed in the early 1990s. After reviewing this emissions estimates for this category and being unable substantiate them, the District developed a new methodology for estimating emissions in this category. The revised methodology substantially reduced the estimate of NOx emissions from this category. See Table A-2 below. See also SJVAPCD, "2007 Area Sources Emissions Inventory Methodology, 050-Industrial Natural Gas Combustion," June 13, 2006.

      The District also made revisions to the methodology for estimating emissions from agricultural burning of prunings and field crops and weed abatement. See SJVAPCD, "2007 Area Sources Emissions Inventory Methodology, 670-Agricultural Burning," June 9, 2008. Many of these changes inventory improvements were made in the period between adoption of the 2007 Ozone Plan and the initial draft of the 2008 PM2.5 Plan. See Draft 2008 PM2.5 Plan, Appendix B, December 2007.
      Collectively, these revisions reduce the total 2002 base year NOx and VOC inventory by approximately 12 percent and 2.3 percent, respectively. 2011 Ozone SIP Revisions, p. B-9. See also Table A-3 below. 
      From late 2007 until mid-2009, California experienced an economic recession that significantly reduced activity levels in and associated emissions from the State's construction and goods movement sectors. 2011 Ozone SIP Revisions, Appendix B. CARB estimates economic growth rates will return to normal levels by the 2017-2018 time period. 2011 Ozone SIP Revisions, Appendix B. As a result, projected emission levels from these categories in the years up to 2017-2018 are now lower than were originally projected in the 2007 Ozone Plan and 2007 State Strategy as submitted in November 2007.
      Recession-caused decreases in emissions do not affect either the Plan's modeling validation years (1999/2000), base year (2002), or future year (2020 and 2023) inventories and thus do not change the carrying capacity estimates in the Plan (that is, they do not in themselves affect the target level of overall emissions needed to demonstrate attainment) or the starting point for the reasonable further progress demonstration. Their principal effect is to reduce the reductions needed from the SIP's control strategy to demonstrate RFP in the years prior to 2018.

3.  Evaluation and Conclusions
      The emissions inventories were made available to the public for comment at the same time as the draft 2007 Ozone Plan and draft 2007 Statewide Strategy and were subject to public hearing as part of final version of the Plan and Strategy. See SJVAPCD Governing Board Resolution, 07-04-11a, April 30, 2007, p. 3 and CARB Resolution No. 07-28, p. 3. Revisions to the inventory were also made available to the public for comment prior to adoption. See CARB, "Notice of Public Meeting to Hear a Report on Staff's Review of Additional Local Emission Controls in The San Joaquin Valley," November 2, 2007; SJVUAPCD, Draft 2008 PM2.5 Plan, Notice of Public Workshops; CARB, Notice of Public Hearing to Consider a Status Report on the State Strategy for California's 2007 State Implementation Plan and Consider Approval of Proposed Revisions for the 8-Hour Ozone and Minor Technical Revisions to the PM2.5 SIP Transportation Conformity Budgets," June 20, 2011.
      Consistent with the 8-hour ozone implementation rule, the SIP uses a 2002 base year inventory. When considered together with the inventory documentation cited above, it contains all the elements required by EPA's emissions inventory guidance. The on-road mobile source inventories use the latest EPA-approved version of the State's mobile source emissions model, EMFAC2007.
      Based on our evaluation of the inventories and the recent changes to them, we propose to approve the 2002 base year emissions inventory in the 2007 State Strategy and the 2007 Ozone Plan as revised by the 2011 Ozone SIP Revisions because it provides for a comprehensive, accurate, current, inventory of actual emissions from all sources of the relevant pollutant at the time of their submittal as required by CAA section 182(a)(1). We also find that the future year baseline inventories in the SJV 2007 8-Hour Ozone SIP provide an adequate basis for the SIP's reasonably available control measure demonstration and the adjusted base year inventory in the RFP demonstration.

B.  Air Quality Modeling
1.  Requirements for Air Quality Modeling 
      CAA section 182(c)(2)(A) requires states with ozone nonattainment areas classified as serious or above to submit plans that demonstrate attainment of the applicable standard as expeditiously as practicable but no later than the applicable attainment date. The attainment demonstration must be based on photochemical grid modeling or another analytical method determined by the EPA Administrator to be at least as effective. Under the ozone implementation rule (40 CFR § 51.908; see 70 FR 71612 at 71624), the attainment demonstration is due within three years of the area's designation as nonattainment and should include technical analyses to locate and identify sources of emissions that are causing violations of the 8-hour ozone standard within the nonattainment area.
      Air quality modeling is used to establish emissions attainment targets, the combination of emissions of ozone precursors that the area can accommodate without exceeding the NAAQS, and to assess whether the proposed control strategy will result in attainment of the NAAQS. Air quality modeling is performed for a base year and compared to air quality monitoring data in order to evaluate model performance. Once the performance is determined to be acceptable, future year changes to the emissions inventory are simulated to determine the relationship between emissions reductions and changes in ambient air quality, and to show that the emission reductions are sufficient for attainment of the standard. The procedures for modeling ozone as part of an attainment SIP are contained in EPA's "Guidance on the Use of Models and Other Analyses for Demonstrating Attainment of Air Quality Goals for Ozone, PM2.5, and Regional Haze." EPA-454/B-07-002, April 2007 ("Guidance"). 

2. Modeling in the SJV 2007 Ozone Plan
      The Central California Ozone Study (CCOS) comprises a field study data collection and processing, air quality modeling, and the continuing data analysis of ozone formation in the San Joaquin Valley and neighboring areas. CCOS is a multi-million dollar cooperative effort involving California cities, State and local and air pollution control agencies, federal agencies, industry groups, academics, and contractors. Meteorological and air quality field study data for CCOS were collected during the 4 months from June through October 2000 and included five several-day intensive monitoring periods. The CCOS ozone episode selected for modeling was July 31-August 2, 2000. CARB also modeled July 9-13, 1999, using routinely available meteorological and air quality data. CARB modeled these with the Comprehensive Air Quality Model with Extensions (CAMx), with meteorological fields from the Mesoscale Model version 5 (MM5).
      The 2007 Ozone Plan's air quality modeling is discussed in the Executive Summary (p.ES-8) and Chapter 3 "What is Needed to Demonstrate Attainment?" with detailed descriptions and results in Appendix F "Photochemical Modeling Support Documents." An additional Plan component is the CARB Staff Report, which includes Appendix C, a Modeling Protocol. Finally, CARB provided an Unmonitored Area Analysis in a separate document.

a.  Conceptual Description 
      A "conceptual description" is a qualitative way of characterizing the nature of an area's nonattainment or regional haze problem. It can be helpful in identifying potential stakeholders and for developing a modeling protocol; it could influence the choice of air quality model, modeling domain, grid cell size, priorities for quality assuring and refining emissions estimates, and the choice of initial diagnostic tests to identify potentially effective control strategies. In general, a conceptual description is useful for helping a state or tribe identify priorities and allocate resources in performing a modeled demonstration. 
      The Guidance (pp. 126-128 (pdf. 135-137)) lists examples of key components of such a description:  local vs. regional nonattainment problem; vertical and horizontal extent of high concentrations; characteristic spatial patterns; monitored violations at locations subject to mesoscale wind patterns (e.g., at a coastline) differing from the general wind flow; recent changes in precursor emissions in or near the nonattainment area; trends in design values or other air quality indicators that have accompanied emissions changes; spatial pattern to the trends; past modeling results; distinctive meteorological measurements coinciding with exceedances.
      2007 Ozone Plan's conceptual description has components in several places, including Chapter 3 (pp. 3-1  -  3-4 (pdf. 3-6)), with similar material in the Staff Report p. 1 (pdf. 13) and in greater detail in section 1.3 of the Modeling Protocol (pp. 6-8 (pdf. 12-14)). These Plan portions note phenomena conducive to high ozone concentrations in the San Joaquin Valley. These include the Sierra Nevada, Tehachapi, and South Coast mountain ranges that surround the SJV except toward the north, and which restrict air flow and ventilation. The summers are hot with little rain fall or cloud cover (Fresno, in the southern SJV, averages 36 days per year with temperatures 100°F or hotter), and with frequent inversions that trap pollutants below them. Sea breezes (or "marine flows") may bring pollutants from coastal areas into the SJV from the northwest. Recirculation of SJV pollutants can occur via nighttime drainage winds ("slope flows"), which return pollutants that were transported up into mountain valleys during the day. Recirculation can also occur via the "Fresno eddy", a counterclockwise flow that returns polluted air that would otherwise escape through southern mountain passes. All of these contribute to the buildup of ozone and precursors, due to enhanced photochemical formation and to restricted dispersion. Also noted are various flow patterns, including transport between the SJV and both the Sacramento Valley to the north and the San Francisco Bay Area to the northwest. The Protocol's descriptions of the episodes modeled provide additional information on the conditions leading to high ozone.
      EPA believes that the conceptual description of the ozone problem in SJV provided in the Plan forms an adequate basis for the development of the modeling protocol and the analysis work.

b.  Modeling Protocol
      A modeling protocol should detail and formalize the procedures for conducting all phases of the modeling study, such as describing the background and objectives for the study, creating a schedule and organizational structure for the study, developing the input data, conducting model performance evaluations, interpreting modeling results, describing procedures for using the model to demonstrate whether proposed strategies are sufficient to attain the NAAQS and/or regional haze goals, and producing documentation to be submitted for EPA Regional Office review and approval. The Guidance (p. 134 (pdf. 143)) lists topics to be addressed in the modeling protocol:
   1.     Overview of Modeling/Analysis Project
         a. Management structure
         b. Technical committees or other communication procedures to be used
         c. Participating organizations
         d. Schedule for completion of attainment demonstration or uniform rate of progress analyses
         e. Description of the conceptual model for the nonattainment area (or Class I area(s))
   2.   Model and Modeling Inputs
         a. Rationale for the selection of air quality, meteorological, and emissions models
         b. Modeling domain

         i. Methods used to quality assure emissions, meteorological, and other model inputs
   3.   Model Performance Evaluation
         a. Describe ambient data base
         b. List evaluation procedures
         c. Identify possible diagnostic testing that could be used to improve model performance
   4.   Supplemental Analyses
         a. List additional analyses to be completed to corroborate the model attainment test
         b. Outline plans for conducting a weight of evidence determination, should it be necessary
   5.   Procedural Requirements
         a. Identify how modeling and other analyses will be archived and documented
         b. Identify specific deliverables to EPA Regional Office
      2007 Ozone Plan's modeling protocol ("Protocol") is contained in Appendix C of the of the Staff Report, as noted above. 
      The Protocol covers the most important topics recommended in the Guidance, as discussed following subsections. EPA believes the protocol is adequate for developing the attainment demonstration.
      
c.  Air Quality Model Selection
      A model should meet several general criteria for it to be a candidate for consideration in an attainment demonstration. Guidance, p. 136 (pdf. 145). These general criteria are consistent with requirements in 40 CFR § 51.112 and 40 CFR part 51, Appendix W. The Guidance does not recommend a specific model for use in the attainment demonstration. At present, there is no single model which has been extensively tested and shown to be clearly superior than its alternatives. Thus, 40 CFR Part 51 Appendix W does not identify a "preferred model" for use in attainment demonstrations of the ozone NAAQS. Based on the language in Appendix W, models used for these purposes should meet requirements for "alternative models". 
      States/Tribes should use a non-proprietary model, which is a model whose source code is available for free (or for a "reasonable" cost). Furthermore, the user must be able to revise the code to perform diagnostic analyses and/or to improve the model's ability to describe observations in a credible manner. The model should meet several additional prerequisites to be used to support an attainment demonstration:
   1. revised in response to a scientific peer review;
   2. appropriate for the specific application on a theoretical basis;
   3. used with a data base which is adequate to support its application;
   4. shown to have performed well in past ozone or PM modeling applications (or if it is the first application, then the State should note why it believes the new model is expected to perform sufficiently); and
   5. applied consistently with the protocol on methods and procedures.
      2007 Ozone Plan's Model selection is discussed in the Protocol (p. 20 (pdf. 26)). CARB considered the SAQM, CMAQ, and CAMx models. The SARMAP model was applied in 1994 to the SJV, but its photochemical mechanism and numerical transport schemes were out of date, and costly to update. CMAQ was considered a viable option, though with limited application to California. CAMx was selected because it was felt to be faster running, it incorporates several probing tools (DDM and PA; see discussion of diagnostic evaluation in Air Quality Model Performance subsection below; CMAQ did not include these at that time), and the initial investigation showed it to have greater flexibility and ease of set up, as well as better performance based on limited testing.
      Any of the three candidate models would have been acceptable. CAMx is explicitly mentioned in EPA Guidance (Table 13.1, p. 139 (pdf. 148)), and EPA believes that CAMx is an adequate model for the ozone attainment demonstration. 
      2007 Ozone Plan's chemical mechanism selection was the California Statewide Air Pollution Research Center (SAPRC). The Plan's Chapter 3 notes that SAPRC is more complete than some other mechanisms such as Carbon Bond IV (CBIV), though it can be slower running. 2007 Ozone Plan p. 3-6 (pdf. 8). The Protocol noted (p. 31 (pdf. 37)) that SAPRC was the most up-to-date mechanism available at the time and has often been applied in California.
      SAPRC is cited multiple times in EPA Guidance Appendix B summarizing model performance evaluations (p. 243 (pdf. 242)), and CARB provides several good rationales for using it. EPA believes it is an adequate chemical mechanism for use in the attainment demonstration modeling.
d.  Episode Selection
      The Guidance discusses several criteria for selecting time periods to model (p. 140-147 (pdf. 149-156)). Experience has shown that evaluation ozone response to control strategies should rely on modeling of full synoptic cycles, preferably including ramp-up and ramp-down days. It is desirable to include a variety of meteorological conditions (regimes or episode types), concentrations near the area's design value, periods with extensive meteorological and air quality databases, and a sufficient number of days so that the modeled attainment test may be applied over multiple days. Episode types may be identified using qualitative procedures such as reviewing weather maps and wind patterns, or more quantitative procedures, such as Classification and Regression Tree (CART) analysis or a principal component analysis (PCA). 
      2007 Ozone Plan's episode selection is discussed in Chapter 3 and in the Protocol. The rich meteorological and air quality database developed during the 2000 CCOS field study was a key consideration in selecting episodes to model. CCOS included a network of upper-air and surface meteorological monitoring stations in addition to the existing routine networks, with yet additional measurements including some from instrumented airplanes made during five intensive operational periods (IOPs). The chosen July 31-August 2, 2000 episode coincided with one of the IOPs. Meteorological and air quality characteristics of this episode are detailed starting at Protocol p. 14 (pdf. 21). The maximum 1-hour ozone concentration was 151 ppb and occurred on August 2[nd] at Edison, southeast of Bakersfield in the southern SJV. The maximum 8-hour ozone concentration was 106 ppb and occurred on August 2[nd] at Parlier, southeast of Fresno in the south-central SJV. Depending on the day, from 11 to 19 of a total of 25 SJV monitors exceeded the 8-hour ozone NAAQS during the episode. Protocol p. 15 (pdf. 21).
      Based on historical meteorological comparisons, July 1999 was another period especially conducive to ozone formation. Also, the Bay Area Air Quality Management District believed ozone at the time was representative of their concentrations, so that the modeling could be useful for the Bay Area as well as for the SJV. The July 11-12, 1999 period was also chosen for modeling, even though it had only routine meteorological and air quality data were available for it. Chapter 3, p. 3-7 (pdf. 9). The maximum 1-hour ozone concentration in the SJV was 156 ppb and occurred on July 8th at Parlier. The maximum 8-hour ozone concentration in the SJV was 122 ppb and occurred on July 11[th] at Clovis, northeast of Fresno in the south-central SJV. Depending on the day, from 13 to 19 of a total of 20 SJV monitors exceeded the 8-hour ozone standard during the episode. (Protocol p. 13 (pdf. 19))
      Four episodes were originally under consideration (the above two, September 17-21, 2000, and August 8-15, 2002), but due to time and resource constraints the decision was made to focus on the July 2000 and July 1999 episodes, especially after initial modeling of the September 2000 episode showed poor performance. Chapter 3, p. 3-6, (pdf. 8); Protocol p. 11 (pdf. 17).
      Both of the modeled episodes displayed concentrations near the monitors' ozone design values and had meteorological features typical of high ozone such as slope, eddy, and marine flows (noted in the "Conceptual Description" discussion above) and transport patterns characteristic of Central California. Chapter 3, p. 3-7 (pdf. 9).
      EPA believes that the chosen episodes provide an adequate basis for the attainment demonstration.
e.  Model Domain and Spatial Resolution 
      The model domain is chosen based the nature of the area's ozone problem and the scale of the emissions that affect the nonattainment area and may be subject to control strategies. Isolated nonattainment areas that are not affected by regional transport of ozone and its precursors may be able to use a relatively small domain. Some areas of the western U.S. may fall into this category. The modeling domain should be designed so that all major upwind source areas that influence the downwind nonattainment area are included in the modeling domain. The influence of boundary conditions should be minimized to the extent possible. Guidance p. 153 (pdf. 162).
      For the horizontal resolution of the coarse portions of regional grids, we recommend a grid cell size of 12 km if feasible, but not larger than 36 km. For urban and fine scale portions of nested regional grids, it may be desirable to use grid cells about 4 km, but not larger than 12 km. States/Tribes should examine past model applications and data analyses for their area when choosing the fine grid resolution. Past model applications and data analyses may help determine whether a grid cell size as small as 4 km (or smaller) is necessary for a particular area. Model performance and the relative response to emissions controls should be considered in the decision. States/Tribes should consider diagnostic tests to assess the difference in model performance and response from varying model grid resolution, particularly in oxidant-limited areas. All ozone monitor locations within a nonattainment area should ordinarily be placed within the fine scale portion of a nested regional grid if nested models are used. Guidance p. 157 (pdf. 166).
      Vertical resolution chosen will vary depending on the application. There is no correct minimum number of vertical layers needed in an attainment demonstration. Greater resolution allows more precise estimation of mixing heights and avoids unrealistic step increases in mixing; alignment with the layers in the meteorological model can affect accuracy; the lowest layer should generally by no more than 50 meters thick; resolution above the boundary layer can generally be coarser. Recent applications of one atmosphere models (with model tops at 100 millibars) have used anywhere from 12 to 21 vertical layers with 8-15 layers approximately within the boundary layer (below 2500 m) and 4-6 layers above the Planetary Boundary Layer (PBL). Guidance p. 159 (pdf. 168).
      2007 Ozone Plan's modeling domain is shown in Figure 4.2 of the Protocol (p. 27 (pdf. 33)), and was chosen with the objective of including all of the Central Valley of California and upwind areas. It includes most of California south of Mt. Shasta and north of Los Angeles, and extends from Pacific Ocean to the central Mojave Desert and Nevada.  The grid horizontal resolution used is 4 km; the full grid is 185 x 185 cells. Protocol p. 26 (pdf. 32). The July 2000 episode used 20 layers, while the July 1999 episode used 16 layers. Protocol p. 27 (pdf. 33)
      Given the topography of the SJV, which has bounding mountains to the east, south, and west but which is open to the north and northwest and therefore subject to transport of ozone and emissions of ozone precursors from the Sacramento Valley and from the San Francisco Bay Area, the model domain encompasses the SJV nonattainment area as well as areas likely to contribute to its ozone problem. The boundaries are in rural northern California, the Nevada desert, mountains to the south, over the Pacific ocean, all areas with low emissions and so the model boundary conditions are unlikely to have a substantial effect on the simulations. The 4 km grid horizontal resolution used is considerably more refined than the 12 km Guidance recommendation, and the number of layers is consistent with the range in the Guidance. EPA believes the chosen modeling domain is adequate for the attainment demonstration.

f.  Initial and Boundary Conditions 
      If there is no larger regional model application available, then it is recommended that background boundary conditions be used to specify initial and boundary concentrations for the attainment demonstration modeling. However, concentration fields derived from a larger domain regional or global chemistry model (i.e. nesting approach) is considered more credible than the assumption of static concentrations, since the pollutant concentration fields reflect simulated atmospheric chemical and physical processes driven by assimilated meteorological observations. Therefore, we recommend using boundary conditions derived from a regional or global scale model, whenever possible. We recommend using a "ramp-up" period by beginning a simulation prior to a period of interest to diminish the importance of initial conditions; we recommend a ramp-up period of at least 2-3 days for ozone. Diagnostic testing which indicates a large impact on the model results from initial or boundary conditions may indicate that the domain is not large enough or the ramp-up period is too short. In either case, it should generally be assumed that initial and boundary conditions do not change in the future. The use of altered initial or boundary conditions in the future year should be documented and justified. Guidance p. 153 (pdf. 162).
      2007 Ozone Plan's initial and boundary conditions are discussed starting at Protocol p. 36 (pdf. 42). Generally defaults from earlier EPA guidance document "Guideline for the Regulatory Application of the Urban Airshed Model", EPA, (EPA-450/4-91-013, July 1991) were used as a starting point, but these were checked against available ozonesonde data and aircraft measurements. Final decisions on the initial and boundary conditions were made jointly by CARB, the Bay Area Air Quality Management District, the San Joaquin Valley Air Pollution Control District, and the Sacramento Municipal Air Quality Management District. Protocol, p. 36 (pdf. 42); table of values on following page. The boundary conditions were left unchanged for simulation of future years, consistent with the EPA Guidance recommendation. A two-day "ramp-up" period was used for both episodes, to minimize the impact of uncertain initial conditions. Protocol p. 39 (pdf. 45).
      EPA believes that the procedure used to determine boundary and initial conditions is adequate for the attainment demonstration.
      
g.  Meteorological Model Selection and Setup
      Generally a standard meteorological model should be used. The recommended approach for generating the meteorological data needed to conduct the attainment demonstration is to apply dynamic meteorological models with four dimensional data assimilation (FDDA). These models use the fundamental equations of momentum, thermodynamics, and moisture to determine the evolution of specific meteorological variables from a given initial state. When modeling past events, the use of data assimilation helps to "nudge" solutions so that they do not diverge greatly from the actual observed meteorological fields. A major benefit of using dynamic meteorological models is that they provide a way of consistently characterizing meteorological conditions at times and locations where observations do not exist. Examples of frequently used meteorological models are listed below (Guidance p. 160 (pdf. 169)):
         * The Penn State University / National Center for Atmospheric Research Mesoscale Model version 5 (MM5)
         * The Regional Atmospheric Modeling System (RAMS)
         * The Weather Research and Forecasting Model (WRF)
      A description of the methods used to generate the meteorological fields should be included in the modeling protocol. In cases in which standard meteorological modeling (e.g. MM5, RAMS, or WRF in a retrospective analysis mode) is not used, it is recommended that a detailed description of the technique that is used to generate the three-dimensional meteorological fields be shared with the appropriate EPA regional office(s) prior to conducting the air quality modeling analysis. Guidance p. 161 (pdf. 170).
      The meteorological model domain must be large enough to contain the photochemical modeling domain. It is expected that most attainment demonstrations will cover large areas and use nested grids. The outermost grid should capture all upwind areas that can reasonably be expected to influence local concentrations of ozone, and/or PM2.5. One should extend the grid 3 to 6 cells beyond the domains of each air quality modeling grid to avoid boundary effects. EPA recommends that the dynamic meteorological models use the same grid resolution as desired for the air quality model applications. However, poor meteorological model performance or the extra costs incurred may not warrant finer resolution; in these specific situations it is recommended that the air quality model application use available results from meteorological models on the next coarser scale. Guidance p. 161 (pdf. 170). 
      Physics options in meteorological models allow users to select how a given feature will be simulated. For example, there may be several options for specifying the planetary boundary layer scheme or the cumulus parameterization. In many situations, the "optimal" configuration cannot be determined without performing an initial series of sensitivity tests which consider various combinations of physics options over specific time periods and regions. While these tests may not ultimately conclude that any one configuration is clearly superior at all times and in all areas, it is recommended that these sensitivity tests be completed, as they should lead to a modeling analysis that is best-suited for the domain and period being simulated. Typically, the model configuration which yields predictions that provide the best statistical match with observed data over the most cases (episodes, regions, etc.) is the one that should be chosen, although other more qualitative information can also be considered. Additionally, model configurations should be designed to account for the pollutants and time periods that are of most interest. Guidance p. 162 (pdf. 171).
      2007 Ozone Plan's meteorological model selection is discussed starting at Protocol p. 19 (pdf. 25). CARB considered the NCEP Eta model, as well as RAMS, MM5, and WRF. The Eta model has mainly been used for weather forecasting and not as a research tool, whereas RAMS showed some poor characteristics when used for air quality modeling by the Bay Area Air Quality Management District, and WRF has been little tested for SIP air quality modeling. MM5, on the other hand has been used extensively for SIPs, including by CARB, and so was chosen as the meteorological model.
      2007 Ozone Plan's meteorological model domain consists of three nested grids. The innermost is just larger than the photochemical domain that it supplies meteorological fields to; it has 189 x 189 cells, each 4 km on a side. This is nested within a 12 km resolution grid covering the entire State of California, and that in turn is nested within an outer 36 km grid that stretches inland to New Mexico and a similar distance west over the Pacific Ocean, and that extends from southern Canada to the tip of the Baja California peninsula. Protocol p. 23 (pdf. 29). Boundary conditions for the inner two grids are derived from the output of the next larger grid each is nested within. The July 2000 episode used 50 vertical layers, and the July 1999 episode used 30 layers. FDDA was used only for the outer two grids; data from some 300 surface and 25 upper air meteorological stations was available for FDDA for the year 2000 CCOS episode.

      2007 Ozone Plan's physics options are listed starting at Protocol p. 29 (pdf. 35), such as Kain-Fritsch cumulus parameterization for the outer grids (2000 episode only). The Protocol also states that many combinations of model options were tested before settling on the final choices. Some of these options are discussed in the following subsection on meteorological model performance.
      EPA believes that the meteorological model choice and setup are consistent with the Guidance, and are adequate for use in the attainment demonstration modeling.

h.  Meteorological Model Performance
      EPA recommends that States/Tribes devote appropriate effort to the process of evaluating the meteorological inputs to the air quality model as we believe good meteorological model performance will yield more confidence in predictions from the air quality model. This evaluation should determine if the meteorological model output fields represent a reasonable approximation of the actual meteorology that occurred during the modeling period. This can be done via an operational evaluation (i.e., quantitative, statistical, and graphical comparisons). A second objective of the evaluation should be to identify and quantify the existing biases and errors in the meteorological predictions in order to allow for an downstream assessment of how the air quality modeling results are affected by issues associated with the meteorological data. This can be done via a more phenomenological assessment, i.e., generally qualitative comparisons of observed features vs. their depiction in the model data. Guidance p. 163 (pdf. 172).
      Operational Evaluation: The operational evaluation results should focus on the values and distributions of specific meteorological parameters as paired with and compared to observed data. It is recommended that the observation - model matching be paired as closely as possible in space and time. Typical statistical comparisons of the key meteorological parameters will include: comparisons of the means, mean bias, mean normalized bias, mean absolute error, mean absolute normalized error, root mean square error (systematic and unsystematic), and an index of agreement. For modeling exercises over large domains and entire ozone seasons or years, it is recommended that the operational evaluation be broken down into individual segments such as geographic sub-regions and/or months/seasons to allow for a more comprehensive assessment of the meteorological strengths and weaknesses. 
      Phenomenological Evaluation: Within the conceptual description of a particular modeling exercise, it is recommended that the specific meteorological parameters that influence air quality be identified and qualitatively ranked in importance. When evaluating meteorological models or any other source of meteorological data, the focus of the phenomenological evaluation should be on those specific meteorological phenomena that are thought to strongly affect air pollution formation and transport within the scope of a specific analysis. It is expected that this event-oriented evaluation will need to summarize model performance in terms of statistical metrics such as probability of detection and false alarm rate. As an example of a potential phenomenological analysis, many regional air quality modeling exercises attempt to assess the effects of transport of emissions from one area to a downwind area with an intent to establish source-receptor relationships. For these types of modeling analyses, accurate transport wind trajectories are needed to properly establish these source-receptor linkages. In this type of model application, a useful event-based meteorological evaluation would be to compare model-derived trajectories versus those based on ambient data to determine what error distance can be associated with the model fields.
      2007 Ozone Plan's Meteorological Model Performance is discussed starting at Appendix F p. F-61 (pdf. 63). Performance statistics are presented in graphical form for various sub-regions of the SJV. They generally show results averaged over multiple sites within each sub-region, and are only a subset of the many site-specific plots that were examined during development of the meteorological modeling. There are a) time series plots over the days of each episode showing observed and simulated wind speed, wind direction, or temperature, b) scatter plots of wind speed gross error against wind speed root mean square error, and c) scatter plots of temperature gross error against temperature bias. The scatter plots include lines indicating performance benchmarks. The plots are provided for the 1999 episode staring at p. F-67 (pdf. 69), and for the 2000 episode at p. F-79 (pdf. 81). Finally, maps of horizontal wind vectors are included for the 2000 episode with various physics options, starting at p. F-89 (pdf. 91).
      For the 1999 episode, statistics and plots were prepared for three different MM5 runs: without FDDA, with FDDA, and with FDDA but excluding data from short (2 meter) meteorological towers. CARB notes that FDDA improved results, but excluding the 2 meter data made little difference. The regular FDDA run of MM5 was used for the air quality modeling. CARB provided summaries of some of the results: For the Bay Area region, wind speeds were generally underpredicted and temperatures showed good agreement with observations, while for the Sacramento region wind speed performance was good ,and temperatures tended to be underpredicted during the day and overpredicted during the morning. For the Central, Southern, and Northern San Joaquin regions, winds tended to be underpredicted some, and again temperatures tended to be underpredicted during the day and overpredicted during the morning. The simulations were the result of substantial effort by the CARB and the Bay Area Air Quality Management District, and though not ideal, were deemed acceptable for use in modeling. (see results summary staring at p. F-65 (pdf. 67).
      For the 2000 episode, statistics and plots were prepared for six different MM5 runs: four produced by the National Oceanic and Atmospheric Administration (NOAA) with alternative land-surface model physics options and roughness lengths, and two produced by CARB, with and without FDDA. These runs had various choice of soil physics and boundary layer parameterizations. After noting the variability of results for different locations, CARB states that the NOAA runs with increase roughness length tended to worsen performance for temperature. CARB also states that all of the FDDA runs did fairly well for the wind field, but for temperature the initial NOAA run performed the best. (Although for the Angiola temperature time series included in the documentation, the CARB runs look better. Figure 1-12(a), p. F-87 (pdf. 89). The initial NOAA run of MM5 was used for the air quality modeling. (see results summary staring at p. F-77 (pdf. 79).
      CARB states that, in addition to these operational evaluation analyses, qualitative performance analyses of the meteorological model were undertaken. These included comparison of modeled and observed wind patterns, to ensure that the model is reproduce phenomena known to occur in the SJV, such as the sea breeze, the Fresno eddy, and slope and drainage flows. They also included comparison of wind profiler observations with the simulated wind field at the profiler location, and of upper air observations with simulated mixing layer height. p. F-64 (pdf. 66).
      The operational evaluation undertaken by CARB is consistent with the recommendations in the EPA Guidance, in terms of meteorological parameters examined, statistics computed, and the consideration of differing sub-regions within the model domain. The CARB qualitative analyses mentioned above are also consistent with the EPA Guidance recommendations for a phenomenological evaluation. EPA believes that the meteorological model evaluation and the model performance are adequate to support the air quality model for the attainment demonstration.

i.  Emission Inventory
      Air quality modeling requires emission inputs for base case, baseline, and future modeling years. Preparation of emissions data for air quality models for the base and future years requires several steps. First, States and Tribes need to compile base-year inventories for their modeling region (e.g., the States and Tribes in the modeling grid). For ozone model applications, emission inventories should include a complete accounting of anthropogenic and biogenic VOC (speciated), NOx, and CO. Second, modelers must collect "ancillary data" associated with the inventories, which prescribes the spatial, temporal, and chemical speciation information about the emission inventory. Third, modelers use the ancillary data for "emissions modeling". Emissions models spatially, temporally, chemically, and vertically allocate emission inventories to the resolution needed by air quality models. Fourth, modelers must collect data on growth rates and existing control programs for use in projecting the base year emission inventories to the future year, and then use an emissions model to prepare that future year inventory data for input to the air quality model. Fifth, emissions inventories that reflect the emissions reductions needed for attainment will have to be prepared for air quality modeling.
      2007 Ozone Plan's emissions inputs are discussed starting at Protocol p. 40 (pdf. 46) start. The Protocol provides description of the modeling inventory preparation process. The topics covered include: quality assurance checks, the effects of growth and of the application of control measures, temporally resolved emissions for some larger point sources, temporal allocation of annual emissions to account for monthly and weekly variations, diurnal profiles of emissions, temperature dependence of emissions from some source types, California-specific vehicle emissions from the EMFAC model, a summary of some of the algorithms and inputs to the BEIGIS biogenic emissions model, spatial allocation of the various source category emissions into model grid squares (via known coordinates for point sources and for links of the roadway network, land use and demographic spatial surrogates for area source categories), speciation of VOC emissions into particular chemical species needed by the photochemical model's chemical mechanism, and speciation of NOx into NO and NO2.
      The Protocol's description of the emissions input process is fairly comprehensive, and covers all the key topics in the EPA Guidance. EPA believes that the emission inventory prepared for input to the air quality model is adequate to support the attainment demonstration.

j.  Air Quality Model Performance 
      Model performance can be assessed in terms of its ability to replicate observed concentrations of ozone and its precursors (operational evaluation), and in terms of the model's ability to correctly portray physical processes, and thus its ability to simulate the effect of emission changes (diagnostic evaluation).
       For the operational evaluation, useful statistical metrics include mean normalized bias (MNB), mean normalized gross error (MNGE), peak bias (APPB), and peak error (APPE). The defining formulas are at Guidance p. 198 (pdf. 207). Other statistics such as mean bias, mean error, root mean square error, correlation coefficients, etc. should also be calculated to the extent that they provide meaningful information. Graphical analyses can also be useful, such as time series and scatter plots of modeled vs. observed concentrations, spatial plots or animations of modeled ozone in each grid cell with observed values noted for monitor locations. EPA no longer recommends specific performance goals for statistical metrics, and cautions against their use as "pass/fail" tests. Guidance p. 216 (pdf. 225). Instead, the results of various tests and analyses should be weighed qualitatively to assess the adequacy of model performance. Appendix B to the Guidance lists sets of performance goals and results that have been used in recent model evaluations.
      For the diagnostic evaluation, the Guidance discusses a number of approaches, including observational models, probing tools, receptor models, retrospective analyses, and sensitivity analyses. Guidance p. 208 (pdf. 217). Observational models include the use of indicator species ratios that give clues about which processes are dominant, and whether VOC or NOx is the limiting precursor for ozone formation. Probing tools include source apportionment tools that track the chemical products of emissions from specified source groups, the direct decoupled method (DDM) that reports model sensitivity to input changes without rerunning the model, and process analysis (PA) that tracks the contributions of particular physical and chemical process to model results. A retrospective analysis compares modeled trends to observed trends given known emission changes over a historical period. Sensitivity analyses explore the model response to changes in important inputs such as total emissions, alternative boundary conditions, alternative meteorological models or model setups, alternative vertical layer schemes, and finer or coarse grid resolution. All of these methods can help to determine whether the model responds in a physically reasonable way to change, and to identify inputs that may need further refinement.
      2007 Ozone Plan's air quality model performance is discussed briefly in 2007 Ozone Plan Chapter 3, and in detail in Appendix F. Chapter 3 states: "In general, modeling of these episodes met performance standards, but some concentrations were under-predicted at sites in the SJVAB." p. 3-7 (pdf. 9). Appendix F lists statistics that were calculated to evaluate model performance for 1-hour ozone and 8-hour ozone (Table 2-1, p. F-99 (pdf. 101)); these are the substantially same as the statistics recommended in the EPA Guidance. The exception is that instead of the peak bias and peak error, a comparable "unpaired peak ratio" ("UPR") statistic is listed; here "unpaired" means that concentrations are not paired hour by hour, but rather the peak concentration for the day is considered, regardless of the particular hour. The abbreviations used in the Plan also differ from EPA's: EPA's mean normalized bias MNB is called just NB, and mean normalized gross error MNGE is called just GE. The evaluation sets a benchmark performance goals for NB of being with 15 percent, and for GE of being within 30 percent; these were carried forward from the earlier EPA guidance on the 1-hour standard. Appendix F, p. F-95 (pdf. 97) and p. F-97 (pdf. 99). Since the SJV modeling domain has complex flow and topography, these statistics were calculated for 15 sub-regions, to assess performance throughout the air basin instead of lumping the disparate locations together in a single metric, which could obscure local performance problems. An additional criterion of a concentration of at least 85 ppb within 15 km of the monitor (p. F-96 (pdf. 98)) is imposed for choosing which days to include in the calculation of relative response factors (RRFs); see the following subsection on the Modeled Attainment Test.
      The numeric values for the statistics are not presented in the Plan, but they are portrayed graphically. In addition to time series plots of monitored and modeled CO, ozone, NO, and NO2, Appendix F has scatter plots of normalized bias (NB) against the UPR. These are presented for both 1-hour and 8-hour ozone, for each sub-region, and for each of the two modeled episodes. 
      The 1999 episode performance is summarized on p. F-102 (pdf. 104), followed by a table showing whether each day meets the RRF inclusion criteria for each sub-region (tables on p. F-103 (pdf. 105)). The time series plots start at p. F-104 pdf.106, and the scatter plots start at p. F-109 (pdf. 111)). For the Central and Southern SJV regions, ozone is stated to be underpredicted during the day and overpredicted during the morning, while for the Northern SJV region ozone is stated to be predicted well. Performance for NO2 is stated to vary over the three regions, and for NO to be somewhat underpredicted.
      The 2000 episode performance is summarized starting at p. F-113 (pdf.115), followed by a table showing whether each day meets the RRF inclusion criteria for each sub-region (tables on p. F-116 (pdf.118)). The time series plots start at p. F-117 (pdf.119), and the scatter plots start at p. F-122 (pdf. 124). For the Central and Southern SJV regions, ozone is stated to be in excellent agreement with observations, while for the Northern SJV region ozone on some days is overpredicted. Performance for NO2 is stated to vary over the three regions, and for NO to be good.
      Examination of the 2000 episode time series plots showed that there tends to be overprediction in the San Francisco Bay Area and Northern SJV regions, slight overprediction in the Sacramento and Central SJV regions. For the Southern SJV region, which had the highest ozone concentrations, there is some underprediction on the highest days, and some overprediction on other days, though the disagreement was not large. Overall performance appears to be good.
       Model Performance for Southern SJV Sub-Region, July 2000 Episode
      Source: Plan Appendix F, Figure 2-12, p. F-120 (pdf. 122).
In addition to these statistics and graphics that are part of an operational evaluation, the Plan lists sensitivity tests that were undertaken. Table 2-3, p. F-100 (pdf. 102). These included typical diagnostic tests such as zeroing out biogenic, anthropogenic, or mobile emissions; changing ozone boundary conditions; changing NOx initial conditions; and doubling biogenic emissions. In the "Results for Model Sensitivity Tests," the Plan provides table of the ozone changes at each monitoring station, and color-coded maps showing the results over the entire modeling domain, and some brief explanatory text. In each case, the model responded in a reasonable way to the changes; for example there were substantial ozone decreases when biogenic emissions were removed, and modest increases when the ozone boundary condition is increased. In a number of cases with reduced or removed emissions, there were ozone increases immediately downwind of a few urban areas; this is explained by noting that the removed NOx emissions were no longer titrating ozone. The effect of ozone boundary condition changes was mainly at the outer domain boundaries, which provides assurance that the model results are not overly driven by the boundary conditions, which can be relatively uncertain. These tests show that the model is performing in a physically reasonable way.
An extensive set of performance statistics and sensitivity analyses was undertaken to assess model performance, consistent with the Guidance, and the model was shown to perform well. EPA believes the model performance is adequate for conducting the attainment demonstration. 

k.  Modeled Attainment Test
      A modeled attainment test is an exercise in which an air quality model is used to simulate current and future air quality. If future estimates of ozone concentrations are less than the NAAQS, then this element of the attainment test is satisfied. Our recommended test is one in which model estimates are used in a "relative" rather than "absolute" sense. That is, we take the ratio of the model's future to current (baseline) predictions at monitors. We call these ratios relative response factors, RRFs. Future ozone concentrations are estimated at existing monitoring sites by multiplying the modeled relative response factor at locations "near" each monitor by the observation-based "baseline" design value for the monitor. The resulting predicted "future concentrations" are compared to NAAQS. Guidance p. 15 (pdf. 24).
      Future concentration 
      = (baseline design value) * (model future prediction) / (model baseline prediction)
      = (baseline design value) * RRF
      After analyzing how RRFs vary with the number of days modeled and with the choice of minimum ozone threshold, EPA recommended several criteria for day selection to ensure that the RRFs are robust in the face of natural variability (Guidance p. 146 (pdf. 155)):
      * If there are 10 or more days with daily maximum 8-hour average baseline modeled ozone > 85 ppb, then use an 85 ppb threshold.
      * If there are less than 10 days with daily maximum 8-hour average baseline modeled ozone > 85 ppb, then reduce the threshold down to as low as 70 ppb until there are 10 days in the mean RRF calculation.
      * If there are less than 10 days with daily maximum 8-hour average modeled ozone > 70 ppb, then use all days > 70 ppb.
      * Don't calculate an RRF for sites with less than 5 days > 70 ppb.
       2007 Ozone Plan's NAAQS attainment test is discussed in two places in Appendix F, starting at p. F-3 (pdf. 5), with a repetition at p. F-96 (pdf. 98) of the RRF inclusion criterion of a concentration of at least 85 ppb within 15 km of the monitor. Tables on p. F-128 (pdf. 130) give the number of days meeting the NB and GE performance goals discussed in the previous subsection, and so available for the RRF calculations for each sub-region for the 1999 and the 2000 episodes. The Plan provides an RRF table and ozone isopleth diagrams ("carrying capacity diagrams") for each monitoring site, for the two future years of 2020 and 2023. Each table has a column for every day modeled in the two episodes, and has entries for observed and modeled peak concentration, modeled peak within 15 km, design value, average of the modeled peak over days eligible for inclusion in the RRF calculation, and the future year concentration within 15 km. The ratio of the latter two is the RRF itself, which is not explicitly shown. Below each table are four ozone isopleth diagrams, which show ozone concentrations for various combinations of NOx and VOC emission reductions (0%, 20%, 40%, and 60% each); note that the reductions are relative to future year emissions without new controls beyond the baseline. The isopleths show the ozone result with and without the application of the RRFs, and without and without an "offset" of 40 ppb (which is assumed to be a background value not affected by emission reductions), for a total of four combinations.
      The attainment test was based on the RRF incorporating the offset. Protocol, p. 98 (pdf. 104). The reductions needed by the plan overall were driven by results at the Arvin monitor in the southern SJV. 2007 Ozone Plan, p. 3-8. This site has a base year design value of 114 ppb, and according to the isopleth diagram (or rather interpolation based on the ozone concentrations and the percent NOx reduction it corresponds to, assuming zero percent benefit from additional VOC control), a 47 percent emission reduction is required for attainment (Chapter 3, p. 3-8, (pdf. 10); Appendix F, p. F-38, (pdf. 40); isopleth diagram with RRFs and with 40 ppb offset). This translates into a 75 percent reduction from base year NOx emission levels of 642 tpd, or an attainment target of 160 tpd. Chapter 3, p. 3-8, (pdf. 10); also Plan Executive Summary p. ES-8.
      With respect to the isopleths or "carrying capacity diagrams", Chapter 3 states that "it is assumed that emission patterns, VOC reactivity and other modeling parameters hold constant over time. This assumption implies that controls are applied evenly throughout the Valley... if transportation patterns in 2008 are extremely different ... it might not be reasonable to assume that ... same ozone concentration at the same site... When considering all uncertainties in modeling, however, this variation is considered minor." 2007 Ozone Plan, p. 3-13. In other words, when total emissions no more than the levels indicated on the carrying capacity diagram, it is assumed that the NAAQS is attained. This is assumed even though the model response would be slightly different if it directly simulated the control measures themselves, since their effects are not necessarily evenly applied to all locations in the SJV.
      The Plan applies the modeled attainment test in accordance with EPA Guidance, except that the Plan's version is more conservative, since it assumes a constant 40 ppb background. Although the 2023 effect of new control measures was not directly modeled, as the Plan states, given all the uncertainties the carrying capacity approach used is acceptable. EPA believes that the Plan's modeled attainment test was correctly applied, and that the modeling demonstrates attainment of the ozone NAAQS.

l.  Unmonitored Area Analysis
      An unmonitored area analysis (UAA) uses a combination of model output and ambient data to identify areas without a monitor that might exceed the NAAQS in the base year or after application of the control strategy. This is necessary because the recommended modeled attainment test based on relative reduction factors may be applied only at monitor locations, and is particularly necessary in nonattainment areas where the ozone or PM2.5 monitoring network just meets or minimally exceeds the size of the network required to report data to Air Quality System (AQS). The analysis should include, at a minimum, all nonattainment counties and counties surrounding the nonattainment area (located within the State). In order to examine unmonitored areas in all portions of the domain, it is recommended to use interpolated spatial fields of ambient data combined with gridded modeled outputs. Guidance p. 29 (pdf. 38). EPA's MATS software can perform this calculation, but other methods may also be used. Due to the location of monitored data, the results of the analysis are less certain than for the modeled attainment test and should be handled on a case by case basis, possibly by additional analyses or tracking. Guidance pp. 32 and 33 (pdf. 41 and 42), respectively.
      Gradient-adjusted spatial fields are first created for the base year. Future year estimates can then be created by applying gridded RRFs to the gradient-adjusted spatial fields. The basic steps are as follows:
   1. Interpolate base year ambient data to create a set of spatial fields;
   2. Adjust the spatial fields using gridded model output gradients (base year values);
   3. Apply gridded model RRFs to the gradient-adjusted spatial fields; and
   4. Determine if any unmonitored areas are predicted to exceed the NAAQS in the future.
      2007 Ozone Plan's unmonitored area analysis is discussed in CARB's Unmonitored Area Analysis document cited above. The 2007 Ozone Plan original submittal section F.4 entitled "Analysis of Model-Simulated, Unmonitored Peaks" contained only a placeholder sentence (p. F-14 (pdf. 16)), but CARB later submitted its Unmonitored Area Analysis that uses EPA's MATS software. This analysis followed the four steps laid out in the Guidance, and provided maps at each step, colored according to the resulting ozone level (or the RRF, for step 3). Around each monitor the maps show include a rectangle containing a 7 x 7 set of 4 km grid cells, portraying the area that monitor is presumed to represent in the EPA Guidance modeled attainment test. CARB notes that the monitors show adequate coverage of the regions with elevated ozone concentrations, with the possible exception of a single (orange-colored) grid cell in the southern SJV that is at the edge of several monitor rectangles. CARB suggests that a source category with emissions that were overestimated at the time of the modeling, unspecified natural gas combustion, may be responsible for the higher value in that cell. Finally, CARB notes that the recent relocation of the Arvin monitor toward the west will better cover this area.
      Additional details of the CARB analysis of this grid cell would have been desirable. However, given the uncertainty of the analysis and the lack of a strong gradient in the step 4 fields, there do not appear to be any unmonitored NAAQS violations. The relocation of the Arvin monitor may be able to provide additional assurance that the potentially high ozone in this grid cell is an artifact of the modeling. EPA believes that the unmonitored area analysis was properly performed, and that its results support the attainment demonstration.

m.  Weight of Evidence Determination
      States/Tribes should always perform complementary analyses of air quality, emissions and meteorological data, and consider modeling outputs other than the results of the attainment test. Such analyses are instrumental in guiding the conduct of an air quality modeling application. Sometimes, the results of corroboratory analyses may be used in a weight of evidence determination to show that attainment is likely despite modeled results which may be inconclusive. The further the attainment test is from being passed, the more compelling contrary evidence produced by corroboratory analyses must be to draw a conclusion differing from that implied by the modeled attainment test results. Guidance p. 17 (pdf. 26). Supplemental analyses could include additional modeling using alternative models and inputs, modeling apportionment and process analysis tools, alternative metrics (such as change in the number of grid cells above the NAAQS), trends in ambient air quality, trends in emissions, receptor modeling, and indicator species approaches.

Future Design Value < 62 ug/m[3], all monitor sites
Basic supplemental analyses should be completed to confirm the outcome of the modeled attainment test
Future Design Value 82 - 87 ppb, at one or more sites/grid cells
Future Design Value 14.5-15.5 ug/m[3], at one or more sites/grid cells
Future Design Value 62-67 ug/m[3], at one or more sites/grid cells
A weight of evidence demonstration should be conducted to determine if aggregate supplemental analyses support the modeled attainment test
Future Design Value > 88 ppb, at one or more sites/grid cells
Future Design Value > 15.5 ug/m[3], at one or more sites/grid cells
Future Design Value > 68 ug/m[3], at one or more sites/grid cells
More qualitative results are less likely to support a conclusion differing from the outcome of the modeled attainment test.
      
      2007 Ozone Plan's weight of evidence determination is discussed in Plan Appendix F and also the CARB Staff Report's Appendix B. These documents largely cover the same material, except that CARB Staff Report, Appendix B has an additional heading "Characterization and Frequency of Episodic Conditions" that provides detail on the different meteorological conditions associated with ozone exceedances (CARB Staff Report, Appendix B p. 9 (pdf. 11)), and its coverage of "Precursor Trends" is somewhat different (Appendix B, p. 17ff (pdf. 19ff). Since Appendix F is part of the Plan per se, and also appears to have been written later, EPA considers it to be the Plan's weight of evidence analysis.
      The Plan's Appendix F concludes with "Corroborative Analyses/Weight Of Evidence Elements" (p. F-138 (pdf. 140)), which contains supplemental analyses in support of the attainment demonstration. These include ozone air quality trends, meteorologically adjusted ozone trends, and precursor emission and ambient trends, all of which show continued progress toward NAAQS attainment. 
      The trends for 8-hour ozone design value and maximum concentration among the worst 30 days each year show just a small amount of progress over the 1990-2005 period. The 8-hour ozone design value (which is the running 3-year average of the 4[th] highest daily ozone value for each year) shows slightly more progress, and the decline in the number of 8-hour exceedance days is substantial. Appendix F, Figure 5-1, p. F-138 (pdf. 140). There has also been substantial progress in most of the sub-regions within the SJV, though the Sequoia area has worsened, and progress at the Arvin site has been less than at other locations. Appendix F, Figure 5-4, p. F-143 (pdf. 144).
      When the average of the Top 10, Top 20, and Top 30 concentrations for each year is adjusted to remove for the effect of unfavorable meteorology via a regression procedure, the downward trends appear stronger, though there are high values in 2003 and 2004. Appendix F, Figure 5-7, p. F-148 (pdf. 150).

      NOx and VOC (comparable to "ROG" in the Plan documents) emissions have had a steady downward trend between 1990 and 2005. Appendix F, Figures 5-11 and 5-12, p. F-151, (pdf. 153).
      Photochemical Assessment Monitoring Stations (PAMS) measurements of ambient concentrations of NOx and VOC, and also the reactivity of the VOC mix, have also showed steady declines. Progress was fairly flat during 1999-2002, and NOx progress is less than for the VOC and reactivity metrics. Appendix F, Figure 5-13, p. F-152 (pdf. 154).
      EPA believes that these analyses support the attainment demonstration prediction of ozone NAAQS attainment, and constitute an adequate weight of evidence determination.
3.  Conclusions 
      The modeling used for the attainment demonstration was made available to the public for comment at the same time as the draft 2007 Ozone Plan, and were subject to public hearing as part of final version of the Plan. 
      The air quality modeling documentation in Chapter 3 and Appendix F of the Plan and CARB's Unmonitored Area Analysis, contains all the elements required by EPA's modeling guidance. The modeling is based on the best and most current information available at the time the plan was developed. Based on our evaluation discussed above, we propose to find that the modeling analysis used for the attainment demonstration in the 2007 Ozone Plan meet the CAA section 182(c)(2)(A) requirement that the plan provide for attainment of the NAAQS, and that the modeling in the 2007 Ozone Plan provides an adequate basis for the Plan's reasonably available control measures, reasonable further progress, and attainment demonstrations. 
      
      
C.  Reasonably Available Control Measures
1.  Requirements for RACM
CAA section 172(c)(1) requires that each attainment plan "provide for the implementation of all reasonably available control measures as expeditiously as practicable (including such reductions in emissions from existing sources in the area as may be obtained through the adoption, at a minimum, of reasonably available control technology), and shall provide for attainment of the national primary ambient air quality standards." The 8-hour ozone implementation rule requires that for each nonattainment area that is required to submit an attainment demonstration, the state must also submit a SIP revision demonstrating that it has adopted all RACM necessary to demonstrate attainment as expeditiously as practicable and to meet any RFP requirements. 40 CFR § 51.912(d).
EPA has previously provided guidance interpreting the RACM requirement in the General Preamble at 13560 and in a memorandum entitled "Guidance on the Reasonably Available Control Measure Requirement and Attainment Demonstration Submissions for Ozone Nonattainment Areas," John Seitz, Director, OAQPS to Regional Air Directors, November 30, 1999 (Seitz memo). In summary, EPA guidance provides that to address the requirement to adopt all RACM, states should consider all potentially reasonable control measures for source categories in the nonattainment area to determine whether they are reasonably available for implementation in that area and whether they would, if implemented individually or collectively, advance the area's attainment date by one or more years.
EPA defines RACM as any potential control measure for application to point, area, on-road and non-road emission source categories that meets the following five criteria. These criteria are that the control measure is (1) technologically feasible, (2) economically feasible, (3) does not cause "substantial widespread and long-term adverse impacts," (4) is not "absurd, unenforceable, or impracticable," and (5) collectively can advance the attainment date by at least one year. General Preamble at 13560. 
      Any measures that are necessary to meet these requirements which are not already either federally promulgated, part of the state's SIP, or otherwise creditable in SIPs must be submitted in enforceable form as part of a state's attainment plan for the area. 70 FR 71612, 71659.

2.  RACM Analysis in the SJV 2007 8-Hour Ozone SIP
      The 2007 Ozone Plan and the 2007 State Strategy are parts of a series of air quality plans that the District and CARB have developed to provide for attainment of the federal air quality standards in the SJV. These planning efforts have resulted in a comprehensive set of rules and programs that address the great majority of emissions sources in the Valley.
      For the SJV 2007 Ozone Plan and the 2007 State Strategy, the District, CARB, and the local agencies (through the SJV's eight metropolitan planning organizations (MPO)) each undertook a process to identify and evaluate potential reasonably available control measures that could contribute to expeditious attainment of the 8-hour ozone standards in the SJV. We describe each agency's efforts below.

a.  District RACM Analysis
      The District's RACM analysis and its results are described in Chapter 6 and Appendix I of the 2007 Ozone Plan. The analysis focused on controls for the categories of stationary and area sources under the District's direct jurisdiction.
      To identify potential RACM, the District reviewed potential measures from a number of sources including but not limited to:
   * control strategies and measures from other districts and agencies, including the South Coast AQMD, Sacramento Metropolitan AQMD, Bay Area AQMD, Ventura County APCD, Houston-Galveston Area Council of Governments, Texas Commission on Environmental Quality, and Fresno Council of Governments;
   * workshops held by the South Coast AQMD and CARB; 
   * existing District controls; 
   * further study measures in the SJV Extreme [1-hour] Ozone Attainment Demonstration Plan;
   * measures suggested by the public in various forums including town hall meetings, workshops on the 2008 Ozone Plan and during public comment periods on the Plan; and
   * recommendations from CARB's 2003 audit of the District.
2007 Ozone Plan, pp. 6-2 to 6-3.
      The identified potential measures, as well as existing District measures, are described by emissions inventory category in Appendix I of the Plan. 
      From this set of potential controls, the District developed a Stationary Source Regulatory Implementation Schedule (2007 Ozone Plan, Table 6-1, revised December 18, 2008) which gives the schedule for regulatory adoption and implementation of the selected RACM measures. See Table C-1 below. The schedule was developed based on a variety of factors, including:
   * technological feasibility and practicality of emission controls;
   * magnitude of emissions from the source category and likely emissions reductions;
   * cost, financial impacts, and potential for socioeconomic impacts (e.g., employment, profitability);
   * District authority and enforceability of emissions reductions;
   * rate and timing of emissions reductions;
   * public acceptability, including interests and concerns of community members;
   * pollutants reduced  -  NOx, or VOC or both;
   * any potential adverse environmental impacts; and.
   * potential for disparate environmental impacts (environmental justice).
2007 Ozone Plan, p. 6-3.
      The District also identified a number of source categories for which feasibility studies to refine the inventory and evaluate potential controls would be done. See 2007 Ozone Plan, Table 6-2. Updated information on the status of many of these feasibility studies can be found in the 2010 Ozone MCR, section 3.2 and the SJV 2008 PM2.5 Progress Report, section 2.2.
      The Plan also includes descriptions of the District's incentive programs (which target on-and off-road engine replacement with an emphasis on diesel engines), its innovative strategies program including its Fast Track emissions reductions measures, and public education efforts. See 2007 Ozone Plan, Chapters 7 and 8, 2010 Ozone MCR, Sections 5 and 6, and SJV 2011 PM2.5 Progress Report, section 2.3 and 2.4

b.  Local Jurisdictions' RACM Analysis
      The local jurisdictions' RACM/RACT analysis was conducted by the SJV's eight MPOs and is summarized in Chapter 9 and described in detail in Appendix C of the 2007 Ozone Plan. This analysis, which focused on potential NOx emissions reductions from transportation control measures (TCM). TCM are generally measures designed to reduce emissions from on-road motor vehicles through reductions in vehicle miles traveled, vehicle trips, and/or traffic congestion. 
      The SJV MPOs developed a local RACM strategy which consisted of two parts: (1) evaluation of potential RACM for advancing the 8-hour ozone standard attainment date and (2) the adoption of a Congestion Mitigation and Air Quality (CMAQ) policy to fund cost-effective emissions reductions projects.
      For the 2007 Ozone Plan, the MPOs evaluated potential TCM through a multi-step process: 
Step 1.  Develop a list of potential reasonably available local control measures. 
      To identify potential measures, the MPOs reviewed measures from previous San Joaquin Valley RACM processes, more recent guidance materials, applicable SIPs, and suggestion made by the public during the District's Town Hall meetings. The resulting list of approximately 20 new measures not previously analyzed for the SJV was organized by CAA Section 108(f) transportation control measure categories. 
Step 2.  Develop emission reduction estimates.
      Emissions reductions estimates were developed for the CAA section 108(f) categories to assess the list of potential RACM identified in Step 1. The methodology used to estimated reductions is described in Appendix C of the 2007 Ozone Plan. In developing these estimates, the MPOs used assumptions that maximized the potential VMT and NOx reduction from each measure. Examples of these assumptions are given on p. 9-5 of the 2007 Ozone Plan. The total maximum reduction in NOx emissions that could be achieved from implementing all the TCM were estimated to be approximately 7 tpd in 2020 and 5 tpd in 2023. 2007 Ozone Plan, p. 9-6.
Step 3. Compare the potential emission reductions against the reductions needed to advance attainment by one year.
      The MPOs used three methods to estimate the reductions needed to advance attainment by one year. The lowest estimate came from determining the NOx reductions required to achieve a 1 ppb decrease in ozone (i.e., the smallest change that is measurable at design monitors). The isopleths for the Arvin and Fresno-Sierra Sky Park monitors show that an 8.8 tpd reduction in NOx will be required to achieve a 1 ppb decrease in ozone concentrations at those monitoring.
      Given that the maximum feasible NOx reductions from potential local RACM were 5 tpd in 2023, the MPOs concluded that combination of local RACM would not advance attainment by a full year and therefore no further efforts to adopt local commitments for the Plan were necessary. 
      Based on the above analysis, the MPOs determined that there were no additional local RACM, beyond those measures already adopted, that would advance attainment of the 8-hour ozone standard in the SJV and thus no additional adoption of measures was necessary. 2007 Ozone Plan, p. 9-7.
      The eight MPOs did commit to adopt a CMAQ policy that includes developing a standardized process across the Valley for distributing, beginning in FY2011, 20 percent of the CMAQ funds to projects that meet a minimum cost-effectiveness. This policy, which as now been adopted, focuses on achieving the most cost-effective emissions reductions, while maintaining flexibility to meet local needs. Id.

c.  State's RACM Analysis
      CARB describes its proposed strategy to reduce emissions from sources within its jurisdiction  -  on- and off-road engines and vehicles, fuels, and consumer products  -  in Chapter 3 of the 2007 State Strategy. California has unique authority under the CAA to adopt standards for most categories of on- and off-road engines and vehicles, subject in most instances only to a waiver by EPA under CAA section 209.
      CARB developed its proposed statewide strategy after an extensive public consultation process to identify potential SIP measures. This process is described in the 2007 Ozone Plan, p. 9-10. It included a SIP Symposium in October 2006 and a workshop in November 2006 to discuss development of potential control concepts for meeting the federal 8-hour ozone and PM2.5 standards. CARB made available a draft of the 2007 State Strategy for public review in April 2007 and then conducted a series of public workshops on the draft. On April 26, 2007, CARB staff released a revised draft of the Proposed State Strategy that incorporated changes based on further staff analysis and public comments. CARB Resolution 07-28, p. 3.
      From this process, CARB identified and committed to develop 15 new defined measures to address California's ozone and PM2.5 nonattainment problem. 2007 State Strategy, p. 65 and CARB Resolution 7-28, Attachment B, p. 8. These measures focused on cleaning up the in-use ("legacy") fleet as well as increasing the stringency of emissions standards for a number of engine categories and further reductions from motor vehicle fuels and consumer products. Many, if not most of these measures, were being proposed and adopted for the first time anywhere in the nation. They built on CARB's already extensive existing program to address emissions of NOx, and VOC from all types of mobile sources, through both regulations and incentive programs, as well as from fuels and consumer products. See 2007 State Strategy, p. 38. Table C-2 lists these measures and their expected action and implementation schedule as initially adopted in 2007 State Strategy as adopting in September 2007. These measures also include one additional measure each from the California Bureau of Automotive Repair and the California Department of Pesticide Regulation. Since 2007, CARB has updated its expected action and implementation dates for a number of its measures. Table C-3 provides the list of these measures as updated in the 2011 Progress Report and 2011 Ozone SIP Revisions.

3.  Evaluation and Conclusions
As described above, the District evaluated a range of potentially available measures for inclusion in its 2007 Ozone Plan and committed to adopt those it found to be technically and economically feasible for implementation in the SJV. The process and the criteria the District used to select certain measures and reject others are consistent with EPA's RACM guidance. We also describe above the measure evaluation processes undertaken by the SJV MPOs and the State. Their processes are also consistent with EPA's RACM guidance. See General Preamble at 13560 and Seitz memo.
Because the SJV is designated and classified as extreme nonattainment for the 1997 8-hour ozone standard, CAA sections 182(b)(2) and (f) require the implementation of RACT for all major sources of VOC or NOx and on all VOC sources covered by an EPA-issued CTG. California submitted the District's revised 8-hour ozone RACT SIP (adopted April 16, 2009) on June 18, 2009. We have proposed to partially approve and partially disapprove this RACT SIP based on our proposed determination that the RACT SIP does not adequately demonstrate compliance with section 182 RACT requirements for ten source categories. See Partial Approval and Partial Disapproval of Air Quality Implementation Plans; California; San Joaquin Valley; Reasonably Available Control Technology for Ozone; Proposed rule, 76 FR 55842 (September 9, 2011). See Table C-4 for a list of rules that covering these 10 categories. Nine of these ten source categories emit VOC emissions, only one, solid fuel-fired boilers, emits NOx. 
Attainment of the 1997 8-hour ozone standard in the SJV depends on significant reductions in NOx from new technologies. Air quality modeling shows that no level of VOC reductions will bring about attainment of the 8-hour ozone standard in the SJV absent these NOx reductions and no reasonable level of VOC reductions will expedite attainment absent significant NOx reductions. See 2007 Ozone Plan, Chapter 3.
Under EPA's longstanding policy, a SIP meets the RACM requirement in CAA section 172(c)(1) if it includes all reasonably available measures that individually or in combination with other such measures can advance attainment of the relevant standard by one year or more, which in this case is from 2023 to 2022. Thus to determine if the SJV Ozone SIP meets this statutory requirement, we must evaluate whether implementation of the missing RACT-level controls on the ten categories will expedite attainment. 
Because attainment of the 1997 8-hour ozone standard depends on NOx reductions and VOC reductions have greatly decreasing benefit as ambient ozone concentrations approach the level of that standard (2007 Ozone Plan, p. 3-9), we have focused our evaluation on the  effect of applying RACT level controls on the solid fuel-fired boiler category. Specifically, we have evaluated whether the potential additional reductions from requiring RACT-level controls on major source solid fuel-fired boilers in the SJV, when combined with other potential RACM/RACT, would provide sufficient additional reductions to attain in 2023. We are using 2023 rather than 2022 because more information is available on projected controlled emissions levels in that year. Fleet turnover from existing mobile source measures will reduce NOx emissions in the SJV by approximately 10 tpd between 2022 and 2023. If additional RACM measures cannot provide sufficient reductions to attain in 2023, they will not be able to provide sufficient emissions reductions in 2022 to both compensate for the reductions lost from fleet turn over in 2022 and to attain.

As shown in Table C-5 below, the projected 2023 NOx emissions level would still be well above the level needed for attainment even after accounting for all controls adopted through 2011, eliminating all emissions from solid-fuel boilers (a level of control well beyond RACT), assuming the maximum feasible reductions from TCM in 2023 (as discussed above), fully crediting reductions from measures that are not currently creditable, and including the estimated reductions from identified measures that are yet to be adopted.

     [3]  SJVAPCD, Staff Report on Rule 4702, Appendix B (August 18, 2011)
Based on our review of these RACM analyses, the District's and California's adopted rules as well as their commitments to adopt and implement controls, and our analysis of the impact of implementing unadopted RACT measures, we propose to find that there are, at this time, no additional reasonably available control measures that would advance attainment of the 1997 8-hour ozone standard in the SJV. Therefore, we propose to find that the SJV 2007 Ozone Plan, together with the 2007 State Strategy, provides for the implementation of RACM as required by CAA section 172(c)(1). 
This proposed finding does not affect the District's continuing obligation under CAA sections 182(b)(2) and (f) and 40 CFR 51.905(a)(1)(ii) to implement RACT on all major sources and all CTG source categories. 
D.  Control Strategy
1.  Requirements for Control Strategies
      CAA section 172(c)(6) requires nonattainment plans to "include enforceable emission limitations, and such other control measures, means or techniques (including economic incentives such as fees, marketable permits, and auctions of emission rights), as well as schedules and timetables for compliance, as may be necessary or appropriate to provide for attainment of such standard in such area by the applicable attainment date...." See also CAA section 110(a)(2)(A). The ozone implementation rule requires all control measures needed for attainment be implemented no later than the beginning of the attainment year ozone season. 40 CFR § 51.908(d). The attainment year ozone season is defined as the ozone season immediately preceding a nonattainment area's attainment date. 40 CFR § 51.900(g).
      In most instances, a nonattainment plan should include the adopted measures it relies on to demonstrate attainment and RFP and/or meet other CAA requirement or should identify the adopted measures it relies on that are already SIP approved, federally promulgated, or otherwise SIP creditable. EPA, however, recognizes that circumstances exist that warrant the initial use of enforceable state commitments in place of these adopted measures. It believes that the CAA allows approval of such enforceable commitments as elements of a CAA control strategy requirement when they are limited in scope. The language in CAA sections 110(a)(2)(A) and 172(c)(6), given above, is quite broad, allowing a SIP to contain any "means or techniques" that EPA determines are "necessary or appropriate" to meet CAA requirements, such that the area will attain as expeditiously as practicable, but no later than the designated date. Furthermore, the express allowance for "schedules and timetables" demonstrates that Congress understood that all required controls might not have to be in place before a SIP could be fully approved.
Commitments approved by EPA under CAA section 110(k)(3) are enforceable by EPA and citizens under, respectively, CAA sections 113 and 304. In the past, EPA has approved enforceable commitments and courts have enforced actions against states that failed to comply with them: see, e.g., American Lung Ass'n of N.J. v. Kean, 670 F. Supp. 1285 (D.N.J. 1987), aff'd, 871 F.2d 319 (3rd Cir. 1989); NRDC, Inc. v. N.Y. State Dept. of Env. Cons., 668 F. Supp. 848 (S.D.N.Y. 1987); Citizens for a Better Env't v. Deukmejian, 731 F. Supp. 1448, recon. granted in par, 746 F. Supp. 976 (N.D. Cal. 1990); Coalition for Clean Air v. South Coast Air Quality Mgt. Dist., No. CV 97-6916-HLH, (C.D. Cal. Aug. 27, 1999). Further, if a state fails to meet its commitments, EPA could make a finding of failure to implement the SIP under CAA section 179(a)(4), which starts an 18-month period for the state to correct the non-implementation before mandatory sanctions are imposed.
      Congress recognized that extreme ozone nonattainment areas may have to rely to a certain extent on new or improved technologies to achieve the emissions reductions needed for attainment and RFP. CAA section 182(e)(5) allows EPA to approve an extreme area plan and attainment demonstration that anticipate development of new control technologies or improvement of existing control technologies. This new technology provision is described further in section II.E of this TSD.

2.  Control Strategy in the SJV 2007 8-Hour Ozone SIP
      For the purposes of evaluating the SJV 2007 Ozone SIP and revised 2007 State Strategy, we have divided the measures relied on in the attainment and RFP demonstrations and to meet the RACM and contingency measures requirements into two categories:  baseline measures and control strategy measures.
      As the term is used here, baseline measures are federal, State, and District rules and regulations adopted prior to 2007 (i.e., prior to the development of the 2007 Ozone Plan and State Strategy) that continue to generate emissions reductions through to the attainment year of 2023 and beyond. 2007 State Strategy, Appendix A, p. 1. Reductions from these measures are incorporated into the baseline inventory and, for the most part, not individually quantified. These measures provide the majority of emissions reductions needed to attain the 8-hour ozone standards in the SJV. See Table F-1 in this TSD.
      Control strategy measures are the new rules, rule revisions, and commitments that provide the additional increment of emissions reductions needed beyond the baseline measures to demonstrate RFP and attainment, meet RACM/RACT, and/or provide for contingency measures.
      We evaluate the control strategy measures in this section. Baseline measures are listed in the Appendices A and B to this TSD.

a.  District Control Strategy Measures and Commitments
      For the 2007 Ozone Plan, the District identified and committed to adopting and implementing 19 new control measures for VOC or NOx. See 2007 Ozone Plan, Table 6-1 (revised December 18, 2008) and SJVUAPCD Governing Board Resolution 07-04-011a, p. 6. In Table D-1 below, we list these measures, which mostly involve strengthening existing District rules, along with their anticipated and actual adoption dates, anticipated and actual final compliance dates, and anticipated and actual initial implementation dates. As can be seen from Table D-1, the District has met its rulemaking schedule to date and has only two rule actions remaining.
      Reductions anticipated to be achievable from each rule at the time the 2007 Ozone Plan was adopted are listed in Table D-2. In Table D-3, we give the current SIP submittal and approval status of the measures in the Plan. In Table D-4,we show the emissions reductions from the rules as adopted. Actual reductions from each rule, once adopted, often differ from those anticipated in the plan. In Table D-5, we list the emissions reductions from rules that are either approved or proposed for approval and therefore are creditable in attainment and RFP demonstrations and for other CAA purposes.
      For a number of potential measures identified during the District's RACM analysis, insignificant information was available to evaluate the feasibility of implementing them in the San Joaquin Valley. For these measures, the District developed a schedule for performing feasibility studies. See 2007 Ozone Plan, page 6-6 and Table 6-4. Measures that are identified as being feasible through these studies will be included in future plan updates with schedules and emissions reduction commitments.
      The District also developed programs to reduce emissions through incentive programs and innovative strategies and programs. See 2007 Ozone Plan, Chapters 7 and 8.

b.  CARB Control Strategy Measures and Commitments
      CARB's commitments in the 2007 State Strategy consist of three parts:
      1. Commitment to achieve emissions reductions by specific dates;
      2. Commitment to propose defined new SIP measures; and
      3. A long-term strategy commitment. 
See 2007 State Strategy, p. 58 and CARB Resolution 7-28, Attachment B, p. 3. 
      The 2007 State Strategy includes enforceable commitments to achieve specific aggregate reductions of NOx and VOC in the SJV by certain dates. See Table D-6 below. The nature of this commitment is described in the State Strategy as follows:
      The total emission reductions from the new measures necessary to attain the federal standards are an enforceable State commitment in the SIP. While the proposed State Strategy includes estimates of the emission reductions from each of the individual new measures, it is important to note that the commitment of the State Strategy is to achieve the total emission reductions necessary to attain the federal standards, which would be the aggregate of all existing and proposed new measures combined. Therefore, if a particular measure does not get its expected emission reductions, the State still commits to achieving the total aggregate emission reductions, whether this is realized through additional reductions from the new measures or from alternative control measures or incentive programs. If actual emission decreases occur in any air basin for which emission reduction commitments have been made that are greater than the projected emissions reductions from the adopted measures in the State Strategy, the actual emission decreases may be counted toward meeting CARB's total emission reduction commitments.

      The 2007 State Strategy also includes CARB's commitments to proposed specific defined measures. See 2007 State Strategy, p. 62 and CARB Resolution 7-28, Attachment B, p. 8, 2011 Progress Report, Appendix B, and 2011 Ozone SIP Revisions, p. A-7. Table D-7 below lists these defined measures and their current adoption and approval status. As can be seen from this table, the State has already adopted and EPA has approved or proposed to approve or is in the process of granting waivers under CAA section 209 to most of these measures. These new measures build on the State's already extensive set of adopted measure; a list of which can be found in the 2007 State Strategy (p. 38) and in Appendix A of this TSD.

      Finally, the 2007 State Strategy includes CARB's long-term commitments to achieve the emissions reductions still needed for attainment after the implementation of the defined measures and the achievement of the specific aggregate emissions reductions. See 2007 State Strategy, p. 66:  "[c]onsistent with section 182(e)(5) of the federal Clean Air Act, [the 2007 State Strategy] includes long-term commitments to achieve the last increment of emission reductions necessary to fully meet attainment goals in the South Coast and San Joaquin Valley." When the 2007 State Strategy was submitted in November 2007, CARB estimated that an additional 81 tpd in NOx reductions beyond those already identified would be needed to attain the 1997 8-hour ozone standard in the San Joaquin Valley. 2007 State Strategy, p. 66. See also Table D-7 above.
      The SJV Ozone Plan and State Strategy, as adopted in 2007, demonstrates that a 75 percent reduction in NOx emissions from the 2002 base year level is necessary to attain the 1997 8-hour ozone standard. A 75 percent reduction from the 2002 base year level equates to an attainment target level of 160 tpd NOx. See 2007 State Strategy, p. 70. In the 2011 Ozone SIP Revisions, CARB revised the 2002 base year NOx emissions downward by 12 percent. This revision to the base year inventory resulted from changes to inventorying methodologies. See Section II.A. of this TSD. 
      Both CARB and EPA recognize that the ideal approach for evaluating the impact of these base year inventory changes on the attainment target would be to perform new air quality modeling. Both Agencies also recognize the time and effort involved in such modeling for an area that is as large and diverse as the San Joaquin Valley. As part of its 2011 Ozone SIP Revisions, CARB has committed to update the SJV 2007 Ozone Plan modeling to reflect the emissions inventory improvements and any other new information by December 31, 2014 or by the date the SIPs are due for the revised 8-hour ozone standard whichever comes first. See CARB Resolution 11-22, p. 3 and 2011 Ozone SIP Revisions, p. B-8.
      As part of the technical support for the 2011 Ozone SIP Revisions, CARB qualitatively evaluated the impact on the attainment target of the revision to this base year inventory and concluded that the 160 tpd target remains viable. See 2011 Ozone SIP Revisions, p. B-9. The 160 tpd target represents a 72 percent reduction off the revised 2002 base year level. CARB also recognized, however, that a reduction of up to 75 percent from the revised baseline (an attainment target level of 141.3 tpd) may be necessary to attain the 1997 8-hour ozone standard in the SJV and reaffirmed its 2007 State Strategy commitment to achieve all emissions reductions that are necessary to provide for attainment. See CARB Resolution 11-22, p. 3.
      As EPA stated in its comment letter on the proposed 2011 Ozone SIP Revisions, we believe that a 75 percent reduction from the base year NOx emissions level, based on the modeling provided in the Plan as submitted in 2007, provides the best available estimate of the NOx reductions needed to reach attainment. In our letter, we recommended that CARB commit to revising the modeling by a specific date and to commit, in the interim, to achieving a 75 percent reduction in NOx from the revised 2002 base year levels by 2023. We noted that these recommendations are consistent with CARB's continuing strong commitment and efforts to achieve the emission reductions needed for attainment of the air quality standards in the San Joaquin Valley and the rest of California.
      In response, CARB included a commitment to update the 2007 SIP modeling for the SJV to reflect emissions inventory improvements and reaffirmed its commitment to achieve the emissions reductions necessary to provide for attainment. CARB has stated that these commitments are sufficient to address the concerns we raised in our comment letter. See 2011 Ozone SIP Revisions Supplement, p. 1.
      EPA notes that the reductions needed to reach a target level of 141 tpd relative to the reductions needed to meet a target level of 160 tpd are fall within CARB's long-term measures (new technologies) commitment under CAA section 182(e)(5).
      In addition to the base year inventory changes, CARB has adjusted future year baseline emissions to reflect methodology changes and improved data. See section II.A.2. of this TSD, Tables D-8 and D-9 show original and adjusted baseline emissions inventories for the source categories. Table D-10 lists the emissions reductions (from the adjusted baseline emissions inventories) that the State now estimates it will achieve from its measures as adopted or revised. Table D-11 shows the reductions from State measures that are current SIP creditable.

3.  Evaluation and Conclusions
a.  Baseline Measures
      As shown in Table F-1, the majority of the NOx emissions reductions and a substantial fraction of the VOC emissions reductions needed to demonstrate attainment of the 1997 8-hour ozone standard in the SJV come from baseline measures. These reductions come from a combination of District and State measures. Reductions needed to demonstrate RFP come entirely from baseline and adopted control measures. See section II.G. of this TSD
      In the past two decades, SJVAPCD has adopted (and in many case revised each several times) more than 70 prohibitory rules that limit emissions of either NOx or VOC including all of the rule adoptions/revisions it committed to as part of its 2007 Ozone Plan. See Appendix B and Table D-1. These rules include controls for boilers, numerous solvent source categories, oil production and refining operations, and agricultural sources. The great majority of these rules and rule revisions are currently SIP approved and as such their emissions reductions are fully creditable in attainment and RFP demonstrations and for other CAA requirements.
      California has adopted standards for many categories of on- and off-road vehicles and engines, gasoline and diesel fuels, and numerous categories of consumer products. The State's measures fall within two categories: measures for which the State has obtained or has applied to obtain a waiver of federal pre-emption under CAA section 209 ("section 209 waiver measure" or "waiver measure") and those for which the State is not required to obtain a waiver ("non-waiver measure"). See EPA's proposed approval and final approval of the SJV 1-Hour Ozone Plan at 74 FR 33933, 33938, (July 14, 2009) and 75 FR 10420, 10424 (March 8, 2010).
i.  Section 209 Waiver Measures
      A waiver under CAA section 209 is, in general, required for most of California's on- and non-road vehicle or engine standards. Examples of State waiver measures are: low emission vehicle program, heavy duty bus standards, and small off-road engine standards. A list of California's waiver measures can be found in the Appendix A of this TSD.
      California's motor vehicle emissions control program predates the first federal statute regulating motor vehicle emissions, the Motor Vehicle Air Pollution Control Act of 1965 (which amended the CAA of 1963). In further CAA amendments, referred to as the Air Quality Act of 1967 (Pub. L. 90-148), Congress allowed the State of California, and only California, a waiver of the Air Quality Act's pre-emption of state emissions standards for new motor vehicles or new motor vehicle engines because of California's pioneering efforts and unique problems. This was not changed when the statute was amended in 1970. The 1977 amendments to the CAA expanded the flexibility granted to California in order "to afford California the broadest possible discretion in selecting the best means to protect the health of its citizens and the public welfare." (H.R. Rep. No. 294, 95th Congr., 1st Sess. 301-2 (1977). So long as California determines that its motor vehicle standards are "in the aggregate" at least as protective of public health and welfare as applicable federal standards, title II of the CAA requires EPA, unless it makes certain findings, to waive the Act's general prohibition on state adoption and enforcement of standards relating to the control of emissions from new motor vehicles or new motor vehicle engines. See CAA section 209, subsections (a) and (b).
      As part of the 1990 Amendments to the CAA, Congress enacted subsection (e) of section 209. In nearly identical language to subsections (a) and (b) of section 209, subsection (e) sets forth the federal pre-emption of state emissions standards for non-road vehicles or engines but allows the State of California, and only California, a waiver of pre-emption (with certain exceptions) under criteria that mirror the section 209(b) waiver provisions for motor vehicles.
      In EPA's review of the California SIP and its many revisions, EPA has historically allowed emissions reduction credit for the motor vehicle emissions standards that are subject to a section 209(b) waiver without requiring California to submit the standards themselves to EPA for approval as part of the California SIP. In this respect, EPA treated these rules similarly to the federal motor vehicle control requirements, which EPA has always allowed states to credit in their SIPs without submitting the program as a SIP revision. Since 1990, EPA has treated California non-road standards for which EPA has issued waivers in the same manner as California motor vehicle standards, i.e., allowing credit for standards subject to the waiver process without requiring submittal of the standards as part of the SIP. In so doing, EPA has treated the California non-road standards similarly to the Federal non-road standards, which are relied upon, but not included in, various SIPs.
      Credit for Federal measures, including those that establish on-road and non-road standards, notwithstanding their absence in the SIP, is justified by reference to CAA section 110(a)(2)(A), which establishes the following content requirements for SIPs: "... enforceable emission limitations and other control measures, means, or techniques (including economic incentives such as fees, marketable permits, and auctions of emissions rights), ... , as may be necessary or appropriate to meet the applicable requirements of this chapter." (emphasis added). Federal measures are permanent, independently enforceable (by EPA and citizens), and quantifiable without regard to whether they are approved into a SIP, and thus EPA has never found such measures to be "necessary or appropriate" for inclusion in SIPs to meet the applicable requirements of the Act. Section 209 of the CAA establishes a process under which EPA allows California's waiver measures to substitute for Federal measures, and like the Federal measures for which they substitute, EPA has historically found, and continues to find, based on considerations of permanence, enforceability, and quantifiability, that such measures are not "necessary or appropriate" for California to include in its SIP to meet the applicable requirements of the Act.
      First, with respect to permanence, we note that, to maintain a waiver, CARB's on-road waiver measures can be relaxed only to a level of aggregate equivalence to the Federal Motor Vehicle Control Program (FMVCP). See section 209(b)(1). In this respect, the FMVCP acts as a partial backstop to California's on-road waiver measures (i.e., absent a waiver, the FMVCP would apply in California). Likewise, Federal non-road vehicle and engine standards act as a partial backstop for corresponding California non-road waiver measures. The constraints of the waiver process thus serve to limit the extent to which CARB can relax the waiver measures for which there are corresponding EPA standards, and thereby serve an anti-backsliding function similar in substance to those established for SIP revisions in CAA sections 110(l) and 193. Meanwhile, the growing convergence between California and EPA mobile source standards diminishes the difference in the emissions reductions reasonably attributed to the two programs and strengthens the role of the Federal program in serving as an effective backstop to the State program. In other words, with the harmonization of EPA mobile source standards with the corresponding State standards, the Federal program is becoming essentially a full backstop to most parts of the California program.
      Second, as to enforceability, we note that the waiver process itself bestows enforceability onto California to enforce the on-road or non-road standards for which EPA has issued the waiver. CARB has as long a history of enforcement of vehicle/engine emissions standards as EPA, and CARB's enforcement program is equally as rigorous as the corresponding EPA program. The history and rigor of CARB's enforcement program lends assurance to California SIP revisions that rely on the emissions reductions from CARB's rules in the same manner as EPA's mobile source enforcement program lends assurance to other state's SIPs in their reliance on emissions reductions from the FMVCP. While it is true that citizens and EPA are not authorized to enforce California waiver measures under the Clean Air Act (i.e., because they are not in the SIP), citizens and EPA are authorized to enforce EPA standards in the event that vehicles operate in California without either California or EPA certification,
      As to quantifiability, EPA's historical practice has been to give SIP credit for motor-vehicle-related waiver measures by allowing California to include motor vehicle emissions estimates made by using California's EMFAC (and its predecessors) motor vehicle emissions factor model in SIP inventories. EPA verifies the emissions reductions from motor-vehicle-related waiver measures through review and approval of EMFAC, which is updated from time to time by California to reflect updated methods and data, as well as newly-established emissions standards. (Emissions reductions from EPA's motor vehicle standards are reflected in an analogous model known as MOBILE.) The EMFAC model is based on the motor vehicle emissions standards for which California has received waivers from EPA but accounts for vehicle deterioration and many other factors. The motor vehicle emissions estimates themselves combine EMFAC results with vehicle activity estimates, among other considerations. See the 1982 Bay Area Air Quality Plan, and the related EPA rulemakings approving the plan (see 48 FR 5074 (February 3, 1983) for the proposed rule and 48 FR 57130 (December 28, 1983) for the final rule) as an example of how the waiver measures have been treated historically by EPA in California SIP actions. The San Joaquin Valley plan was developed using a version of the EMFAC model referred to as EMFAC2007, which EPA has approved for use in SIP development in California. See 73 FR 3464 (January 18, 2008). Thus, the emissions reductions that are from the California on-road "waiver measures" and that are estimated through use of EMFAC are as verifiable as are the emissions reductions relied upon by states other than California in developing their SIPs based on estimates of motor vehicle emissions made through the use of the MOBILE model.
      Moreover, EPA's waiver review and approval process is analogous to the SIP approval process. First, CARB adopts its emissions standards following notice and comment procedures at the state level, and then submits the rules to EPA as part of its waiver request. When EPA receives new waiver requests from CARB, EPA publishes a notice of opportunity for public hearing and comment and then publishes a decision in the Federal Register following the public comment period. Once again, in substance, the process is similar to that for SIP approval and supports the argument that one hurdle (the waiver process) is all Congress intended for California standards, not two (waiver process plus SIP approval process). Second, just as SIP revisions are not effective until approved by EPA, changes to CARB's rules (for which a waiver has been granted) are not effective until EPA grants a new waiver, unless the changes are "within the scope" of a prior waiver and no new waiver is needed. Third, both types of final actions by EPA--i.e., final actions on California requests for waivers and final actions on state submittals of SIPs and SIP revisions -- may be challenged under section 307(b)(1) of the CAA in the appropriate United States Court of Appeals.
      Further statutory support for EPA's long-standing practice is found in CAA section 193. CAA section 193, enacted as part of the 1990 Amendments to the CAA, is a general savings clause that provides for, among other things, EPA statutory interpretations that predate those amendments to remain in effect so long as not inconsistent with the Act. At the time it enacted section 193, Congress did not insert any language into the statute rendering EPA's consistent prior treatment of California's motor vehicle standards inconsistent with the Act. Moreover, where Congress intends state control measures that are otherwise pre-empted under title II of the Clean Air Act to be incorporated into SIPs, it has required that explicitly. See, e.g., section 211(c)(4)(C) (State fuels regulations), section 211(m) (oxygenated gasoline regulations), and section 246 (centrally fueled fleets). Thus, in section 193, Congress effectively ratified EPA's longstanding pre-1990 practice of allowing emissions reduction credit for California standards subject to the waiver process notwithstanding the absence of the standards in the SIP itself.
      As noted above, under the CAA Amendments of 1990, Congress enacted subsection (e) of section 209. In nearly identical language to subsections (a) and (b) of section 209, subsection (e) sets forth the federal pre-emption of state emissions standards for non-road vehicles or engines but allows the State of California, and only California, a waiver of pre-emption (with certain exceptions) under criteria that mirror the section 209(b) waiver provisions for motor vehicles. Congress is presumed to be aware of agency interpretations and its subsequent revision of the statute to add subsection (e) without overruling EPA's interpretation with respect to motor vehicle standards is further compelling evidence that the Agency correctly interpreted congressional intent with respect to crediting California requirements subject to a section 209 waiver without requiring California to submit the standards themselves to EPA for approval as part of the California SIP.
      We believe that section 193 of the CAA, the general savings clause added by Congress in 1990, effectively ratified our long-standing practice of granting credit for the California waiver rules because Congress did not insert any language into the statute rendering EPA's treatment of California's motor vehicle standards inconsistent with the Act. Rather, Congress extended the California waiver provisions to most types of non-road vehicles and engines, once again reflecting Congressional intent to provide California with the broadest possible discretion in selecting the best means to protect the health of its citizens and the public welfare. Requiring the waiver measures to undergo SIP review in addition to the statutory waiver process is not consistent with providing California with the broadest possible discretion as to on-road and non-road vehicle and engine standards, but rather, would add to the regulatory burden California faces in establishing and modifying such standards, and thus would not be consistent with Congressional intent. In short, we believe that Congress intended California's mobile source rules to undergo only one EPA review process (i.e., the waiver process), not two. Even if section 193 did not provide congressional acquiescence as to EPA's treatment of the standards, the Act's structure, evolution, and provision for the waiver of Federal pre-emption for California mobile source emissions standards, as discussed above, support EPA's long-standing interpretation of the CAA to allow California to rely on emissions reductions resulting from waiver measures in SIPs, notwithstanding the waiver measures' absence from the SIP itself.

ii. Non-waiver measures
      These measures include improvements to California's inspection and maintenance (I/M) program, SmogCheck, and cleaner burning gasoline and diesel regulations. Generally, the State's baseline non-waiver measures have been approved by EPA into the SIP and are fully creditable for meeting CAA requirements. See TSD, Appendix A.

      b. Control Strategy
      We propose to approve the SJVUAPCD's commitments to achieve specific aggregate emissions reductions of NOx and VOC by specific years as given in Table 6-2 of the 2007 Ozone Plan. We are not proposing to approve SJVAPCD's commitments to adopt and implement specific control measures on the schedule identified in Table 6-2 (as amended December 18, 2008) in the 2007 Ozone Plan because, as of August 16, 2011 with the adoption of the Rule 4655, these commitments have all been fulfilled.
      We are proposing to approve CARB's commitments to propose certain defined measures, as given in Table B-1 in 2011 Progress Report, Appendix B and 2011 Ozone SIP Revisions. Appendix A-3. See Table D-7 above. We are also proposing to approve CARB's commitment to achieve the total aggregate emissions reductions necessary to demonstrate RFP and to attain the 1997 8-hour ozone standard in the SJV as given in CARB Resolution 07-28 (September 27, 2007), Appendix B, p. 3, whether these reductions are realized from the new measures, alternative control measures, incentive programs, or other emissions decreases in the area. See. This commitment is shown in Table D-6 above.
      The SJV Ozone Plan and State Strategy, as adopted in 2007 demonstrates that a 75 percent reduction in NOx emissions from the 2002 base year level is necessary to attain the 1997 8-hour ozone standard. A 75 percent reduction from the 2002 base year level equates to an attainment target level of 160 tpd NOx. See 2007 State Strategy, p. 70. In the 2011 Ozone SIP Revisions, CARB revised the 2002 base year NOx emissions downward by 12 percent. This revision to the base year inventory resulted from changes to inventorying methodologies. See Section II.A. of this TSD. 
      Both CARB and EPA recognize that the ideal approach for evaluating the impact of these base year inventory changes on the attainment target would be to perform new air quality modeling. Both Agencies also recognize the time and effort involved in such modeling for an area that is as large and diverse as the San Joaquin Valley. As part of its 2011 Ozone SIP Revisions, CARB has committed to update the SJV 2007 Ozone Plan modeling to reflect the emissions inventory improvements and any other new information by December 31, 2014 or by the date the SIPs are due for the revised 8-hour ozone standard whichever comes first. See CARB Resolution 11-22, p. 3 and 2011 Ozone SIP Revisions, p. B-8.
      As part of the technical support for the 2011 Ozone SIP Revisions, CARB qualitatively evaluated the impact on the attainment target of the revision to this base year inventory and concluded that the 160 tpd target remains viable. See 2011 Ozone SIP Revisions, p. B-9. The 160 tpd target represents a 72 percent reduction off the revised 2002 base year level. CARB, however, also recognized that a 75 percent reduction from the revised baseline (an attainment target level of 141.3 tpd) is the outside bound of the NOx reductions needed to attainment the 1997 8-hour ozone standard in the SJV and reaffirmed its 2007 State Strategy commitment to achieve all emissions reductions that are necessary to provide for attainment. See CARB Resolution 11-22, p. 3.
      As EPA stated in its comment letter on the proposed 2011 Ozone SIP Revisions, we believe that the current model's estimate that a 75 percent reduction from the base year NOx emissions level provides the best available estimate of the NOx reductions needed to reach attainment. See Letter, Deborah Jordan, EPA Region 9, to James Goldstene, CARB, July 20, 2011. In our letter, we recommended that CARB commit to revising the modeling by a specific date and that, in the interim, it also commit to achieving a 75 percent reduction in NOx from the revised 2002 base year levels by 2023. We noted that these recommendations are consistent with CARB's continuing strong commitment and efforts to achieve the emission reductions needed for attainment of the air quality standards in the San Joaquin Valley and the rest of California.
      In response, CARB included a commitment to update the 2007 SIP modeling for the SJV to reflect emissions inventory improvements and reaffirmed its commitment to achieve the emissions reduction necessary to provide for attainment. CARB has stated that these commitments are sufficient to address the concerns we raised in our comment letter. See letter, Lynn Terry, CARB, to Deborah Jordan, EPA Region 9, August 10, 2011 submitting supplement information in support of the 2011 Ozone SIP Revisions.
      EPA notes that the reductions needed to reach a target level of 141 tpd relative  to the reductions needed to meet a target level of 160 tpd are attributed to CARB's long-term commitment which is discussed in the next section. 
      
E.  CAA Section 182(e)(5) New Technologies Provision
1.  Requirements of the CAA Section 182(e)(5) New Technologies Provision
For ozone nonattainment areas classified as extreme, the CAA recognizes that these areas may have to rely to a certain extent on new or evolving technologies to achieve the emissions reductions needed to demonstrate attainment, given the relatively long time between developing the initial plan and the degree of emissions reductions needed to attain the standard. These measures would include those that may anticipate future technological developments or future improvements in existing technology as well as those that may require complex analyses and decision making and coordination among a number of government agencies. 
CAA section 182(e)(5) allows EPA to approve provisions in an extreme area nonattainment area plan which anticipate development of new control technologies, or improvement of existing control technologies and to approve an attainment demonstration based on these provisions. However, before EPA can approve these provisions and the attainment demonstration, the state must demonstrate that: 
      1. the provisions are not necessary to achieve the incremental reductions required during the first 10 years after November 15, 1990;  and
      2. the State has submitted enforceable commitments to develop and adopt contingency to be implemented if the anticipated technologies do not achieve the planned reductions.
Under section 182(e)(5), the State must submit its contingency measures no later than 3 years before the original long-term measure was to have been implemented, and they must be adequate to produce emissions reductions sufficient, in conjunction with other approved plan provisions, to achieve the periodic emissions reductions and to attain the ozone standard by the applicable dates. If EPA determines that the extreme area has failed to achieve an emissions reductions requirement set forth in section 182 (b)(1) or (c)(2) and that such failure is due in whole or part to an inability to fully implement the provisions related to new technologies approved pursuant to section 182(e)(5), the Administrator will require the State to implement the contingency measures to the extent necessary to ensure compliance with the emissions reduction requirements of section 182 (b)(1) and (c)(2). EPA will set a schedule for implementing contingency measures upon making a finding of failure to meet a milestone.
The General Preamble further provides that the new technology measures contemplated by section 182(e)(5) may include those that anticipate future technological developments as well as those that require complex analyses, decision making and coordination among a number of government agencies. See General Preamble at 13524. An attainment demonstration that relies on long-term new technology measures under section 182(e)(5) must identify any such measures and contain a schedule outlining the steps leading to final development and adoption of the measures. Id. The General Preamble also provides that EPA will set a schedule for implementing contingency measures upon making a finding of failure to meet a milestone, i.e., to achieve the periodic emissions reductions required by CAA sections 182(b)(1) or (c)(2) or to attain by the applicable dates. Id.

      2.  CAA Section 182(e)(5) New Technologies Provision in the SJV 2007 8-Hour Ozone SIP
      The 2007 8-Hour Ozone SIP demonstrated that 81 tpd of NOx reductions from long-term measures (CARB terminology for the new technologies provisions) were needed in order to attain the 1997 8-hour ozone standard in the SJV by 2024. The District's and State's long-term strategies are discussed in section 11.5 of the 2007 Ozone Plan (pp. 11-5 to 11-10) and on page 54-57 in the 2007 State Strategy. Additional information and updates have been provided by the District in the 2010 Ozone MCR (sections 5 and 6) and the State in the 2009 State Strategy Update (p. 25) and the 2011 Ozone SIP Revisions (Appendix A-4) 
To determine if existing technologies could provide sufficient emissions reductions for attainment, CARB analyzed whether current and foreseeable mobile source NOx controls, if fully deployed, would provide sufficient emissions reductions for attainment in the San Joaquin Valley by 2020. See 2007 State Strategy, p. 54. For this analysis, CARB assumed that all passenger cars would be 10 years old or younger, all diesel trucks would meet the 2010 NOx standards, all diesel construction and farm equipment would meet the most stringent tier 4 standards, all locomotives would meet U.S. EPA's then-proposed 2017 NOx standards, and all the new stationary sources measure in the 2007 Ozone Plan would be fully implemented. This fiscally-unconstrained scenario showed that in 2020 the SJV would still be approximately 35 tpd above its attainment target of 160 tpd of NOx. Id.
The District also evaluated the impact of accelerating the deployment of the cleanest-available on- and off-road engines through incentive fund grants. The District found that even with an investment of $2.5 billion between 2007 and 2023 and no other technology or logistic constraints, portions of the SJV would still not meet the 1997 8-hour ozone standard. 2007 Ozone Plan, Chapter 7.
      CARB has provided a list of potential long-term control measures which include reduced deterioration of emission control equipment in passenger vehicles, tighter engine emission standards, cleaner ground support equipment at airports, and prioritizing federal transportation funding to support air quality goals. See pp. 56-57 of the 2007 State Strategy. It has also provided updates to its list of potential long-term measures in both the 2009 State Strategy update and the 2011 ozone SIP revision. See 2009 State Strategy Status Report, pp. 25-27 and 2011 Ozone SIP Revision, Appendix A, pp. A-8 to A-12. 
To implement the long-term strategy, CARB has committed to a process that will help ensure that the long-term measures are adopted and that reductions are achieved by the beginning of the last full ozone season before the attainment date. CARB is coordinating a government, private and public effort to establish emission goals for critical mobile and stationary emission source categories. The effort includes periodic assessment of technology advancement opportunities and updates to the Board and the public regarding new emission control opportunities and progress in achieving the long-term measure reductions. CARB's commitment for implementing the long-term strategy also includes (a) sharing the results of its efforts to identify emerging emissions reduction opportunities, promising technologies, and  the progress made in developing long-term emission reduction measures with the public through periodic briefings to the Board, workshops, conferences, symposia, website postings and other means, (b) working to secure resources in the future for continuing research and development of new technologies, and (c) development of schedules for moving from control technology research to implementation. Id.
An initial step in the long-term strategy was the signing of a Memorandum of Agreement (MOA) between the U.S. EPA, CARB and the South Coast and San Joaquin Valley Air Districts to commit to developing and testing new sustainable technologies to accelerate progress in meeting air quality goals. The goal of the MOA is to improve air quality by aligning agency research resources, where possible and appropriate, to evaluate innovative technologies that have the potential to reduce emissions, and to develop and assess new monitoring equipment to better measure mobile and stationary source emissions. These agencies also intend to coordinate research efforts with other public and private stakeholders, including other federal departments and agencies and other local and state entities with the goal of using the resources and capacities of a wide sector of government and the business community in projects to develop, demonstrate, and assess new technologies for clean air.
The agencies involved in the MOA have also established a Clean Air Technology Working Group to help bring together the necessary participants (e.g., scientists, engineers, analysts and agency specialists) to achieve the goals of the MOA. 2009 State Strategy Status Report, pp. 25-27. For the San Joaquin Valley, the focus has been on an area that straddles Kern and Tulare counties, which is impacted by mobile source emissions from the goods movement corridor of Highway 99 and Interstate 5, and stationary sources from a variety of emissions sources such as energy production facilities, farms, and agricultural processing operations. The City of Bakersfield is within the focus area of the pilot project. Bakersfield has the highest wintertime PM concentrations in the Valley, and the city of Arvin nearby has some of the highest 8-hour ozone concentrations in the summer.
Other State programs that may achieve emissions reductions to help meet CARB's 182(e)(5) commitment include: 
         * potential co-benefits from California's climate change programs where State legislation (Assembly Bill 32  -  Global Warming Solutions Act of 2006 (AB 32)) aims to reduce greenhouse gases (GHG) in 2020 to 1990 levels or by about 30%. Reducing emissions from combustion sources is at the core of California's AB32 Scoping Plan and is also central to meeting the federal ozone standard. Regulations adopted as part of AB32 will provide emissions reductions that will be incorporated into future air quality plans for ozone and fine particles.
         * California's Air Quality Improvement Program (AQIP) is an incentive program administered by CARB to fund clean vehicle and equipment projects, research on biofuels production, and the air quality impact of alternative fuels, as well as workforce training. The program supports the deployment of hybrid and zero-emission vehicles and other advanced technologies today in order to achieve the large-scale reductions needed in the future. California's large funding commitment for hybrid truck technology provides emissions benefits today as well as likely enabling heavy-duty hybrid trucks to become commonplace in the near future through encouraging production economies of scale. AQIP is also providing vehicle purchaser incentives for zero emission passenger vehicles, plug-in hybrid cars, electric lawnmowers, and demonstration projects for cleaner marine and locomotive engines.
         * California's annual research program, which identifies projects and provides funding to help provide timely scientific and technical information needed for State and local air quality control programs. Specifically, this program supports CARB's mission to understand air pollution health effects and exposures, develop and implement strategies to reduce GHG emissions and energy consumption, and support the development of technologies and non-technological strategies that address multiple air quality priorities.
In addition to its commitment to the process discussed above, CARB has committed to submit an 8-hour ozone SIP revision by 2020 that will: (1) reflect modifications to the 2023 emission reduction target based on updated science and (2) identify additional strategies and implementing agencies needed to achieve the needed reductions by the beginning of the 2023 ozone season. See 2011 Ozone SIP Revision, p. A-8. 
CARB's 2011 Ozone SIP Revision updates and reaffirms both the "long-term strategy commitment to identify and implement advanced technologies to reduce ozone-forming emissions in the State Strategy" and the State's enforceable commitment "to develop, adopt, and submit contingency measures by 2020 if advanced technology measures do not achieve planned reductions." See CARB Resolution 11-22, July 21, 2011. Finally, CARB has committed to meet annually with EPA to discuss strategies to maximize the clean air benefits of emerging advanced technologies and to provide annual summaries of strategies and activities.  In the 2011 Ozone SIP Revision, CARB reasserts its commitment to ensure that measures are identified no later than 2020 and the emissions reductions are achieved by 2023. 2011 Ozone SIP Revision, Appendix A, p. A-8. 
      In addition, the District is pursuing innovative strategies. Its "Fast Track" strategy includes opportunities to reduce emissions from heavy-duty trucks by shifting goods movement to lower-emission alternatives, such as short-sea shipping. In 2010, the U.S. Department of Transportation awarded the Ports of Stockton, West Sacramento, and Oakland with a $30 million grant to move goods between Oakland and the two inland ports over the San Joaquin-Sacramento Delta. 
      The District has also adopted a Technology Advancement Program (TAP) which is its strategic approach to encouraging innovation and development of new emission reduction technologies. The TAP will consist of an ongoing review of new technology concepts, interagency partnerships, funding for technology advancement programs, and collaborations to build and expand local capacity for research and development in the SJV. For more information about the SJV TAP, see http://www.valleyair.org/Grant_Programs/TAP/tap_idx.htm. In addition to the TAP, the District has established a Regional Energy Efficiency Strategy to support technology development and deployment in the Valley. The Regional Energy Efficiency Program lays out goals and measures that will guide the District's actions to reduce emissions caused by electricity and natural gas consumption in residential, industrial, and institutional settings. See 2011 Ozone SIP Revisions, pp. A-11 to A-12.

3.  Evaluation and Conclusion 
CARB and the SJVAPCD have demonstrated a clear need for emissions reduction from new and improved control technologies to reduce air pollution in the SJV. The adopted control measures and enforceable commitments, discussed in section II.D. above, provide the majority, but not all, of the balance of the emissions reductions needed to attain by June 15, 2024. See Table F-3. For the balance of the reductions needed for attainment, the SJV 2007 8-Hour Ozone Plan relies on the State's and District's long-term strategy to develop and deploy new technologies as is allowed under CAA section 182(e)(5). 
Based on our review of the new technologies provisions in the SJV 2007 8-Hour Ozone SIP, we are proposing to approve the CARB's and District's long-term strategy provisions and related commitments in the SJV 2007 8-Hour Ozone SIP under CAA section 182(e)(5). This proposal is based on our proposed findings that these provisions satisfy the two criteria in CAA section 182(e)(5)(A) and (B). 
First, the SJV 2007 8-Hour Ozone SIP does not rely on any of the new technology reductions to demonstrate RFP in any milestone year between 2008 and 2020. Already adopted measures provide for the required RFP in each milestone year from 2008 until the attainment year of 2023. See 2011 Ozone SIP Revision, p. A-3 and section II.G. of this TSD.
Second, CARB has submitted an enforceable commitment to submit adopted contingency measures to EPA by 2020 as required by CAA section 182(e)(5). See CARB Resolution 11-22, July 21, 2011. These contingency measures must be adequate to produce emissions reductions sufficient, in conjunction with other approved plan provisions, to achieve the periodic emissions reductions required by CAA sections 182(b)(1) or (c)(2) and to attain by the applicable dates. See CAA 182(e)(5). Following the State's submittal of these contingency measures, EPA will approve or disapprove the provisions in accordance with CAA section 110.
Both the CARB and the District have taken steps to research, demonstrate and deploy technologies for achieving the needed reductions. These steps include establishing a Technology Advancement Program and funding incentive programs. Both CARB and the District have made commitments to research, evaluate, adopt and implement long-term measures as they are identified. See 2011 Ozone SIP Revision, Appendix A, pp. A-8-A-12.
The 2007 State Strategy includes commitments by CARB to develop and submit revisions to the Strategy by no later than 2020 that will: (1) reflect modifications to the 2023 emission reduction target based on updated science and (2) identify additional strategies and implementing agencies needed to achieve the needed reductions by 2023. See 2011 Ozone SIP Revision, p. A-8. The District also committed to make by the end of 2019 the necessary revisions. 
      CARB has also committed to achieve 81 tpd of NOx reductions in 2023 through new technology measures approved under section 182(e)(5). We note that the amount and relative proportion of reductions from measures scheduled for long-term adoption under section 182(e)(5), as compared to measures already adopted in regulatory form or scheduled for near-term adoption, should clearly decrease in any future SIP update, and that EPA will not approve a SIP revision that contains an increase in the amount or relative proportion of section 182(e)(5) new technology measures without a convincing showing in a SIP revision that the technologies relied upon in the near-term rules have been found to be technologically infeasible or ineffective in achieving the expected emissions reductions.

F.  Attainment Demonstration
1.  Requirement for Attainment Demonstrations
      CAA section 182(c)(2)(A) requires states with ozone nonattainment areas classified as serious or above to submit plans that demonstrate attainment of the applicable standard as expeditiously as practicable but no later than the applicable attainment date. Under the ozone implementation rule (40 CFR § 51.908), the attainment demonstration is due within three years of the area's designation as nonattainment and should include:
      (1) technical analyses to locate and identify sources of emissions that are causing violations of the 8-hour ozone NAAQS within the nonattainment area;
      (2) adopted measure with schedules for implementation and other means and techniques necessary and appropriate for attainment; and
      (3) contingency measures required under section 172(c)(9) of the CAA.
See 70 FR 71612 at 71615.
      The requirements for items 1 and 2 are described in the emissions inventory, air quality modeling, and RACM sections of this TSD. Requirements for item 3 are discussed in the contingency measures sections of this TSD. In this section, we evaluate how these items taken together provide for attainment of the 1997 8-hour ozone NAAQS in the San Joaquin Valley as expeditiously as practicable

2.  Attainment Demonstration in the SJV 2007 8-Hour Ozone SIP
      The attainment demonstration in the 2007 Ozone Plan is given in Section 11.2. It is summarized in Table F-1 below. Table F-2 shows the contributions by the District and CARB to the control strategy.
      Since adoption and submittal of the 2007 State Strategy and the 2007 Ozone Plan, both CARB and the District have adopted most of the measures in their Strategy/Plan, and many have been approved by or submitted to EPA. See Tables D-3 and D-6. The State has also revised parts of the base year and future year baseline emissions inventory to reflect improved methodologies and data. The effect of these revisions to the attainment demonstration are shown in Table F-3.

3.  Evaluation and Conclusions
a. Enforceable Commitments in the Attainment Demonstrations
A portion of the emissions reductions needed to demonstrate attainment of the 1997 8-hour ozone standard in the SJV is in the form of enforceable commitments. We describe these enforceable commitments in section II.C. above. 
In most instances, a nonattainment plan should include the adopted measures it relies on to demonstrate attainment and RFP and/or meet other CAA requirement or should identify the adopted measures it relies on that are already SIP approved, federally promulgated, or otherwise SIP creditable. EPA, however, recognizes that circumstances exist that warrant the initial use of enforceable state commitments in place of these adopted measures. It believes that the CAA allows approval of such enforceable commitments as elements of a CAA control strategy requirement when they are limited in scope. Once EPA determines that circumstances warrant use of an enforceable commitment, EPA considers three factors in determining whether to approve the use of enforceable commitment to meet CAA requirements:  (a) does the commitment address a limited portion of the statutorily-required program; (b) is the state capable of fulfilling its commitment; and (c) is the commitment for a reasonable and appropriate period of time.
As shown in Table F-4 below, reductions in the projected future year baseline inventory from measures already adopted by the District and State (both prior to and as part of the 2007 Ozone Plan as well as the subsequent 2008 PM2.5 Plan) and approved or proposed for approval by EPA provide the great majority of the emissions reductions needed to demonstrate attainment of the 1997 8-hour ozone standard in the SJV. The balance is in the form of either enforceable commitments to specific aggregate emissions reductions by the District and CARB and or emissions reductions from new or improved technologies under CAA section 182(e)(5).
We believe that, with respect to the 2007 SJV 8-hour Ozone SIP, circumstances warrant the consideration of enforceable commitments as part of the attainment demonstration for the SJV. As shown in Table F-1 above, the majority of NOx emissions reductions and a substantial fraction of the VOC reductions needed to demonstrate RFP and attainment in the SJV come from rules and regulations that were adopted prior to 2007, i.e., from the baseline measures. As a result of these State and District efforts, most sources in the San Joaquin Valley nonattainment area are currently subject to stringent rules adopted prior to the State Strategy's and the Plan's development, leaving few opportunities (and generally more technologically and economically challenging ones) to further reduce emissions. In the 2007 Ozone Plan and the 2007 State Strategy, the District and CARB identified potential control measures that could contribute many of the additional emissions reductions needed for attainment. See 2007 Ozone Plan, Appendix I and 2007 State Strategy, Chapter 5. However, the timeline needed to develop, adopt, and implement these measures went many years beyond the November 2007 submittal date of the SJV 8-hour Ozone SIP. These circumstances warrant the District's and CARB's reliance on enforceable commitments as part of the attainment demonstration in the 2007 8-Hour Ozone SIP.  
Given the State's demonstrated need for reliance on enforceable commitments, we now consider the three factors EPA uses to determine whether the use of enforceable commitments in lieu of adopted measures to meet a CAA planning requirements is approvable: (a) do the commitments address a limited portion of the statutorily-required program; (b) is the state capable of fulfilling its commitments; and (c) are the commitment for a reasonable and appropriate period of time.

i.  Commitments are a Limited Portion of Required Reductions
For the first factor, we look to see if the commitment addresses a limited portion of a statutory requirement, such as the amount of emissions reductions needed to demonstrate RFP and attainment in a nonattainment area. For this calculation, reductions assigned to the new technologies provision (CAA section 182(e)(5)) are not counted as commitments.
As shown Table D-12, the remaining portion of the enforceable commitments, after accounting for approved measures and advanced technology measures, needed to demonstration attainment of the 8-hour ozone standard in the San Joaquin Valley are 7.7 tpd of VOC and 4.6 tpd of NOx (the remaining portion of CARB's 2023 NOx commitment). When compared to the total reductions needed to demonstration attainment, the remaining portion of the enforceable commitments represents at most 6.7 percent of the needed VOC and 1.1 percent of the needed NOx. Historically, EPA has approved SIPs with enforceable commitments in the range of 10 percent or less. See our approval of the SJV PM10 Plan at 69 FR 30005 (May 26, 2004), the SJV 1-hour ozone plan at 75 FR 10420 (March 8, 2010), the Houston-Galveston 1-hour ozone plan at 66 FR 57160 (November 14, 2001), proposed approval of the SJV 2007 PM2.5 SIP at 76 FR 41338 (July 13, 2011), and proposed approval of the South Coast PM2.5 SIP at 76 FR 41562 (July 14, 2011).

ii.  The State is Capable of Fulfilling Its Commitment
For the second factor, we consider whether the State and District are capable of fulfilling their commitments.
As discussed above, CARB has adopted and submitted the 2009 State Strategy Status Report and the 2011 Ozone SIP Revisions, which update and revise the 2007 State Strategy. These submittals show that CARB has made significant progress in meeting its enforceable commitments for the San Joaquin Valley. 
The District has already exceeded its commitments for reducing NOx emissions for the attainment year of 2023. See Table D-4. It also has already adopted rules (Rules 9510 and 4320) that are projected to achieve NOx reductions in the attainment year. These reductions, however, are not currently creditable to the attainment and RFP demonstrations. In addition, it has adopt revisions to District Rule 4702 (Reciprocating Internal Combustion Engines) that are likely to achieve substantial NOx reductions. See SJVAPCD, Final Draft Staff Report Proposed Amendments To Rule 4702 (Internal Combustion Engines), August 18, 2011. It has also adopted Rule 4566 (Organic Materials Composting Operations) that will achieve an estimated 19 tpd reductions in VOC (in SIP currency) by 2017. See SJVUAPCD, "Final Draft Staff Report, Revised Proposed New Rule 4566 (Organic Material Composting Operations)," August 18, 2011, Appendix B, p. B-3. Finally, the District is also continuing to work to identify and adopt additional measures to reduce emissions. 
Beyond the rules discussed above, both CARB and the District have well-funded incentive grant programs to reduce emissions from the on- and off-road engine fleets. Reductions from several of these programs have yet to be quantified and/or credited in the attainment demonstration. See, for example, SJV PM2.5 Progress Report, section 2.3
Given the State's and District's efforts to date to reduce emissions, we believe that the State and District are capable of meeting their enforceable commitments to adopt measures to reduce emissions of NOx and VOC to the levels needed to attain the 1997 8-hour ozone standard in the San Joaquin Valley by June 15, 2024.

[1]  Calculated by subtracting from CARB's 2023 46 tpd NOx commitments (Table D-6) the adjustment to baseline from State & federal sources on Table D-8 (21.5 tpd) and emissions reductions from creditable State measures on Table D-10 (19.8 tpd). District has no NOx emissions reductions remaining as commitments. See Table D-5.
iii.  The Commitment is for a Reasonable and Appropriate Timeframe
For the third and last factor, we consider whether the commitment is for a reasonable and appropriate period of time.
In order to meet the commitments to reduce emissions to the levels needed to attain the 1997 8-hour ozone standard in the San Joaquin Valley, the 2007 Ozone Plan and 2007 State Strategy included an ambitious rule development, adoption, and implementation schedules, which both the District and CARB have substantially met. Given that almost all the emissions reductions committed to by District and CARB have already been achieved and the rules to achieve the few remaining ones are schedule for adoption by 2013, EPA considers these schedules to provide sufficient time to achieve the few remaining reductions needed to attain (when considered with the emissions reductions provided by the advanced technology provision) by the applicable attainment date of June 15, 2024. See Table F-4 above. Thus we find that the commitments are for a reasonable and appropriate timeframe. 

b.  Attainment Demonstration
      In order to approve a SIP's attainment demonstration, EPA must make several findings:
      First, we must find that the demonstration's technical bases-emissions inventories and air quality modeling-are adequate. As discussed above in sections II.A. and II.B., we are proposing to approve the revised emissions inventories and to find the air quality modeling adequate to support the attainment demonstration.
      Second, we must find that the SIP provides for expeditious attainment through the implementation of all RACM. As discussed above in section II.C., we are proposing to approve the RACM demonstration in the SJV 2007 8-hour Ozone SIP as meeting the requirements of CAA section 172(c)(1).
      Third, we must find that the emissions reductions that are relied on for attainment are creditable and are sufficient to provide for attainment. As shown on Table F-4., the 2007 8-hour Ozone SIP relies principally on adopted and approved/waived rules to achieve the emissions reductions needed to attain the 1997 8-hour ozone standards in the SJV by June 15, 2024. The balance of the reductions projected to be needed for attainment is currently in the form of enforceable commitments to adopt measures to achieve aggregate tonnage reductions of VOC or NOx in the near term from available and identified technologies and commitments to adopt and submit in the longer term measures relying on the development and deployment of new technologies that will achieve specific aggregate tonnage reductions of NOx. 
      EPA has previously accepted enforceable commitments in lieu of adopted control measures in attainment demonstrations when circumstances warranted them and the commitments meet three criteria. As discussed in above, we proposed to find that circumstances here warrant the consideration of enforceable commitments and that the three criteria are met: 1) the commitments constitute a limited portion of the required emissions reductions, 2) both the State and the District have demonstrated their capability to meet their commitments, and 3) the commitment are for an appropriate timeframe. Based on these conclusions, we are proposing to approve the  enforceable commitments as part of the attainment demonstration in the SJV 2007 8-Hour Ozone SIP.
      CAA section 182(e)(5) allows extreme ozone nonattainment area plans under certain conditions to include provisions for the development of new technologies and allows EPA to approve attainment demonstrations based, in part, on those provisions. For the reasons discussed in section II.E., we are proposing to find that California has met the conditions for relying on new technology provisions in its attainment demonstration for the SJV. 
As discussed above in section IV.C.2. above, the SJV Ozone Plan and State Strategy, as adopted in 2007, demonstrates that a 75 percent reduction in NOx emissions from the 2002 base year level is necessary to attain the 1997 8-hour ozone standard. Since the adoption of the SJV ozone SIP in 2007, the base year NOx emissions level has be revised downward by 12 percent due to new inventory methodologies and data. Both CARB and EPA recognize that the ideal approach for evaluating the impact of these base year inventory changes on the attainment target in the SJV 2007 Ozone Plan would be to perform new air quality modeling, but both also recognize the time and effort involved in such modeling. CARB has committed to update the SJV 2007 Ozone Plan modeling to reflect the emissions inventory improvements and any other new information by December 31, 2014 or by the date the SIPs are due for the revised 8-hour ozone standard whichever comes first. See CARB Resolution 11-22, p. 3 and 2011 Ozone SIP Revisions, p. B-8. EPA is proposing to approve this commitment.
EPA believes that a 75 percent reduction from the base year NOx emissions level from the existing modeling provides the best currently available estimate of the NOx reductions needed to reach attainment. CARB has committed to, and has reaffirmed its commitment to achieve the reductions needed for attainment in the SJV. See CARB Resolution 07-28 (September 27, 2007), Appendix B, p. 3, 2009 State Strategy Status Report, p. 13, and CARB Resolution 11-22, p. 3. It has also stated that these commitments are sufficient to address the attainment needs of the SJV. See 2011 Ozone SIP Revisions Supplement, p. 1. As discussed above, CARB's commitment to achieving 81 tpd of NOx emissions reductions from new technologies is sufficient to cover any reductions that may be needed for attainment due to the changes to the base year inventory.
      For the foregoing reasons, we are proposing to approve the attainment demonstration in the SJV 2007 8-Hour Ozone SIP.
G.  Reasonable Further Progress Demonstrations
1.  Requirements for Reasonable Further Progress Demonstrations
      CAA section 172(c)(2) requires that plans for nonattainment areas provide for reasonable further progress (RFP). RFP is defined in section 171(1) as "such annual incremental reductions in emissions of the relevant air pollutant as are required by [title 1, part D] or may reasonably be required by the Administrator for the purpose of ensuring attainment of the applicable [standard] by the applicable date."
      CAA section 182(b)(1) specifically requires that SIPs for ozone nonattainment areas  classified as moderate or higher demonstrate a 15 percent reduction in VOC emissions between the years of 1990 and 1996. For ozone nonattainment areas classified as serious or higher, CAA section 182(c)(2)(B) also requires the SIPs demonstrate a three percent per year reduction (averaged over three-year periods) of ozone precursor emissions from 1997 until attainment. CAA section 182(b)(1)(D) prohibits states from including emissions reductions from pre-1990 federal motor vehicle control programs in their RFP.
      The ozone implementation rule interprets the RFP requirements for the purposes of the 1997 8-hour ozone standard. It establishes requirements for RFP that depend on the area's classification as well as whether the area has an approved 15 percent reduction plan for the 1-hour ozone standard that covers the entire 8-hour ozone nonattainment area. See 40 CFR § 51.910(d) and 70 FR 71612.  SJV has a fully-approved 182(b)(1) plan for the 1-hour ozone standard that covers the current 1997 8-hour ozone standard nonattainment area. See 62 FR 1150, 1172 (January 8, 1997).  
      For areas with fully-approved 182(b)(1) plans for the 1-hour ozone standard that cover the current 1997 8-hour nonattainment area, the ozone implementation rule requires an RFP plan providing for an average of 3 percent per year of VOC and/or NOx emissions reductions for (1) the 6-year period beginning January 1 of the year following the year used for the baseline emissions inventory; and (2) all remaining 3-year periods after the first 6-year period out to the area's applicable attainment date. 40 CFR § 51.910(a)(1)(ii)(B). Except as specifically provided in CAA section 182(b)(1)(C), emissions reductions from all SIP-approved, federally promulgated, or otherwise SIP-creditable measures that occur after the base year are creditable for purposes of demonstrating that the RFP targets are met. The implementation rule also sets the base year for RFP calculations as 2002. 40 CFR 51.910(d).
      The RFP demonstration must calculate and exclude the non-creditable reductions from the federal motor vehicle control program as described in CAA section 182(b)(1)(D). The method for calculating the target emissions levels is found in Appendix A to the preamble of the ozone implementation rule. See 70 FR 71612 at 71696. 

2.  RFP Demonstration in the SJV 2007 8-Hour Ozone SIP
      California has made several submittals to address the RFP requirement for the 1997 8-hour ozone standard in the SJV. These submittals are:
   1. Chapter 10 in the 2007 Ozone Plan (adopted April 30, 2007)
   2. Appendix D of the 2007 State Strategy (adopted September 27, 2007)
   3. Enclosure B to the Letter, James Goldstene, Executive Officer, CARB, to Wayne Nastri, Regional Administrator, EPA Region 9, February 1, 2008
   4. Appendix A of the 2011 Ozone SIP Revisions (adopted July 21, 2011).
      For this proposal, we are reviewing the revised RFP demonstration contained in 2011 Ozone SIP Revisions. This revised demonstration incorporates the inventory revisions described in section II.A.2. of this TSD as well as reductions from measures that have been adopted since the 2007 Ozone Plan's submittal. See 2011 Ozone SIP Revisions, p. 2. The revised RFP demonstration is shown in Table G-1 below.

3.  Evaluation and Conclusions
CARB calculated the RFP target levels following the method provided in the ozone implementation rule and preamble. See 40 CFR 51.910 and 70 FR 71612 at 71631-71650. The table provided in the SIP (reproduced in Table G-1 below) follows CARB's standard format for presenting RFP demonstrations.
      In Table G-2 below, we have modified CARB's table to make the calculations easier to follow and to remove reductions from several currently uncreditable District and state rules from the RFP calculations.  We have also removed the contingency reserve.  We discuss contingency measures in section II.J. Table G-3 gives a description of each line in Table G-2.
      As shown in Table G-2, the SJV 2007 8-Hour Ozone SIP provides for RFP in each milestone year. EPA, therefore, proposes to approve the  RFP demonstration.

                                       A
(VOC) Baseline
The total summer season daily VOC emissions in the San Joaquin Valley in the current milestone year (MSY). Total includes benefits from control measures adopted prior to the submittal of the SJV 2007 8-hour Ozone SIP as well as control strategy measures adopted prior to submittal of the 2011 Ozone SIP Revisions. It does not include reductions from SJV Rule 9510.
                                   B (1-3).
Currently uncreditable reductions from DPR's pesticide element and Rules 9410 and 9456.
Reductions for the current MSY from District Rules 9410 and 9456 and CA DPR pesticide element are included in the Baseline. EPA has not yet proposed approved these rules into the SIP and therefore they are not currently creditable in the RFP demonstration.
                                       C

                                       D
MVCP Adjustment
The reductions from the pre-1990 MVCP for on-road vehicles that must be excluded in the RFP demonstration per CAA section 182(b)(1)(D).

H.  Transportation Control Strategies and Transportation Control Measures to Offset Emissions Increases from VMT Increases and to Provide for RFP and Attainment
      1.  Requirements for Transportation Control Strategies and TCM to Offset Emissions Increases from VMT Increases and to Provide for RFP and Attainment
CAA section 182(d)(1)(A) requires that areas classified as severe or extreme submit transportation control strategies and transportation control measures (TCM) sufficient to offset any growth in emissions from growth in vehicle miles traveled (VMT) or the number of vehicle trips, and to provide (along with other measures) the reductions needed to meet the applicable RFP requirement. This CAA section also requires that states choose and implement such measures as are specified in section 108(f), to the extent needed to demonstrate attainment. In selecting the measures, Congress directed that States "should ensure adequate access to downtown, other commercial, and residential areas and should avoid measures that increase or relocate emissions and congestion rather than reduce them."
EPA believes that it is appropriate to treat the three required elements of section 182(d)(1)(A) (i.e., offsetting emissions growth, attainment of the RFP reduction, and attainment of the ozone standard) as separable. EPA has historically interpreted the first element of this CAA provision to allow areas to meet the requirement by demonstrating that emissions from motor vehicles decline each year through the attainment year. General Preamble at 13522.

      2.  Transportation Control Strategies and TCM to Offset Emissions Increases from VMT Increases and to Provide for RFP and Attainment in the SJV 2007 8-Hour Ozone SIP
      Information in 2011 Ozone SIP Revisions reproduced in Table H-1 below shows that on-road mobile source emissions of VOC and NOx decline steadily from 2008 to 2023. This decline in emissions is due to EPA's and California's mobile source programs, California's clean fuels and SmogCheck programs, and CARB's in-use truck and bus rule. As discussed above in section II.D., these programs are fully creditable for SIP planning purposes in attainment and RFP demonstrations, including demonstrating compliance with CAA section 182(d)(1)(A). The on-road emissions in Table H-1 are calculated using EMFAC2007, the most recent EPA-approved mobile source emissions model for California.
      As described above in section II.C., the SJV MPOs evaluated a wide variety of transportation control measures, including those measures listed in CAA section 108(f), and determined that there were no combinations of reasonable measures that would expedite attainment of the 1997 8-hour ozone standard in the SJV. See 2008 Ozone Plan, Appendix C.

3.  Evaluation and Conclusions
      Because VOC and NOx emissions from on-road mobile sources decline steadily over the entire time period covered by the 2007 8-hour Ozone SIP, the SIP does not need to include additional transportation control strategies or TCM to offset growth in emissions from growth in VMT or vehicle trips; therefore, we propose to find that the SJV 2007 8-Hour Ozone SIP meets the first provision of CAA section 182(d)(1)(A). 
      In Association of Irritated Residents v. EPA, 632 F.3d 584 (9th Cir. 2011), the U.S. Court of Appeals for the Ninth Circuit held that, with respect to the requirement to offset any growth in emissions from growth in vehicle miles traveled or the number of vehicle trips, section 182(d)(1)(A) of the CAA requires States to adopt transportation control strategies and measures whenever vehicle emissions are projected to be higher than they would have been had vehicle miles traveled not increased, even when aggregate vehicle emissions are actually decreasing. EPA has filed a petition for rehearing on this issue. Docket Nos. 09-71383 and 09-71404 (consolidated), Docket Entry 41-1, Petition for Panel Rehearing.
      The Ninth Circuit has yet to issue its mandate in the Association of Irritated Residents case, and EPA has not adopted the court's interpretation for the reasons set forth in the Agency's petition for rehearing, pending a final decision by the court. If the court denies the Agency's petition for rehearing and issues its mandate before EPA issues a final rule on the San Joaquin Valley 2007 8-Hour Ozone SIP, then we anticipate that we would not be able to finalize approval of the SIP with respect to the first element of section 182(d)(1)(A). Therefore, in the alternative to the proposed approval, we are proposing to disapprove the SJV 2007 8-Hour Ozone SIP with respect to the first element (i.e., offsetting emissions growth) of section 182(d)(1)(A) based on the plan's failure to include sufficient transportation control strategies and measures to offset the emissions from growth in VMT. If EPA were to finalize the proposed disapproval, the area would be eligible for a protective finding under the transportation conformity rule because the submitted SIP contains adopted control measures and enforceable commitments that fully satisfy the emissions reductions requirements for reasonable further progress and attainment. 40 CFR 93.120(a)(3). 
      
      As discussed above in section II.G., we have proposed to find that the SJV 2007 8-Hour Ozone SIP provides for RFP consistent with all applicable CAA and EPA regulatory requirements; therefore, we also propose to find that the SIP meets the second provision of CAA section 182(d)(1)(A); that is, to include transportation control strategies and TCM as necessary to provide (along with other measures) the reductions needed to meet the applicable RFP requirement. 
      In discussed in sections II.C. and II.F. above, we have determined that the SJV 2007 8-Hour Ozone SIP provides for the implementation of all RACM, including all reasonably available transportation control measures, and provides for expeditious attainment of the 1997 8-hour ozone standard. Therefore, we propose to find that SIP meets the third provision of CAA section 182(d)(1)(A); that is, to include TCM to the extent needed to demonstrate attainment.

I.  Use of Clean Fuels or Advanced Technology for Boilers 

1.  Requirement for the Use of Clean Fuels or Advanced Technology for Boilers
      CAA section 182(e)(3) requires that plans for areas classified as extreme must require each new, modified, and existing electric utility and industrial and commercial boiler that emits more than 25 tpy of NOx to burn as its primary fuel natural gas, methanol, or ethanol (or a comparably low polluting fuel), or use advanced control technology (such as catalytic control technology or other comparably effective control methods). These requirements must be submitted 3 years and be effective 8 years after November 15, 1990.
      Further guidance on this requirement is provided in the General Preamble at 13523. According to the General Preamble, boilers should generally be considered as any combustion equipment used to produce steam and would generally not include a process heater that transfers heat from combustion gases to process streams, a waste heat recovery boiler that is used to recover sensible heat from the exhaust of process equipment such as a combustion turbine, or a recovery furnace that is used to recover process chemicals. It also does not include boilers used primarily for residential space and/or water heating. General Preamble at 13523. 
      Only boilers that actually emit more than 25 tons per year of NOx are affected. Emissions vary from year to year, however, making applicability difficult to determine. Boilers with rated heat inputs of greater than 10-20 million Btu generally have the potential to exceed the 25-tons-per-year limit depending on the fuel type. A source with these high rated heat inputs should therefore be considered affected unless its federally enforceable permit specifically restricts NOx, emissions below 25 tons per year from each boiler. In addition, boilers with rated heat inputs less that 15 million Btu (MMBtu) per hour which are oil- or gas-fired may generally be considered not subject to these requirements since it is unlikely that they will exceed the 25 tpy NOx emission limit. General Preamble at 13524.
      We believe the term "catalytic control technology" in CAA section 182(e)(3) was intended generally to refer to selective catalytic reduction (SCR). SCR is a post-combustion control technology that reduces NOx reductions by injecting ammonia into the flue gas, which then passes through layers of catalyst in a reactor.

      2.  Use of Clean Fuels or Advanced Technology for Boilers Requirements in the SJV 2007 Ozone Plan
      The 2007 Ozone Plan addresses the CAA section 182(e)(3) requirements on page 2-9 and concludes that existing District boiler rules meet this CAA requirement:
      District Rules 4305, 4306, and 4352 address NOx emission limits for the boilers in this category. Most of the boilers under Rules 4305 and 4306 are fired on natural gas and therefore satisfy the requirement of paragraph (A) above. Liquid-fuel fired boilers are also addressed by those rules and the applicable NOx emission limits satisfy the requirement of paragraph (B) above. Solid-fuel fired boilers are addressed by Rule 4352 and the applicable NOx emission limits satisfy the requirement of paragraph (B) above.
      Therefore, the District already complies with this requirement and there is no need to include additional control measures in this plan to satisfy the section of the federal Clean Air Act.
2007 Ozone Plan, p. 2-7.

3.  Evaluation and Conclusion
      SJVAPCD has adopted 6 rules that control NOx emissions from boilers that are potentially subject to the requirements in CAA section 182(e)(3).
      Rule 4305 "Boilers, Steam Generators, and Process Heaters  -  Phase 2" as revised on August 21, 2003 was approved by EPA on May 18, 2004 (69 FR 28061). It applied to any gaseous fuel- or liquid fuel-fired boiler, steam generator, or process heater with a total rated heat input greater than 5 million Btu per hour. The requirements in the rule have now been superseded by those in Rule 4306.
      Rule 4306 "Boilers, Steam Generators, and Process Heaters  -  Phase 3" as revised on October 16, 2008, applies to any gaseous fuel- or liquid fuel-fired boiler, steam generator, or process heater with a total rated heat input greater than 5 million Btu per hour. The NOx emission limits in the rule, which range from 5 ppm to 30 ppm for gaseous fuels and is 40 ppm for liquid fuels, cannot be achieved without the use of advance control technologies. See "Alternative Control Techniques Document--NOx Emissions from Industrial/Commercial/Institutional (ICI) Boilers," Emissions Standards Division, EPA, March 1994 ("1994 ACT"). We approved Rule 4306 (revised October 16, 2008) as a SIP revision on January 13, 2010 at 75 FR 1715. All units subject to Rule 4306 were required to comply with the limits in the rule no later than December 1, 2008. See Rule 4306, section 7.0.
      Rule 4320 "Advanced Emission Reduction Option for Boilers, Steam Generators, and Process Heaters Greater than 5 MMBtu/hr" adopted October 15, 2008 imposes more stringent limits than Rule 4306; however, sources subject Rule 4320 may opt to pay an annual fee in lieu of meeting these limits. Source which opt to pay the annual fee under Rule 4320 are still subject to RACT requirements (Section 5.3.3). EPA approved Rule 4320 into the SIP on March 25, 2011 at 76 FR 16696.
      Rule 4307 "Boilers, Steam Generators, and Process Heaters  -  2.0 MMBtu/hr to 5.0 MMBtu/hr," as revised on October 16, 2008, applies to any gaseous fuel- or liquid fuel-fired boiler, steam generator, or process heater with a total rated heat input greater than 2.0 MMBtu per hour but less than 5.0 MMBtu per hour. EPA approve Rule 4307 (revised October 16, 2008) as a SIP revisions (and as meeting CAA section 182(b)(1) RACT) into the SIP on January 13, 2010 at 75 FR 1715. On May 19, 2011, the District slightly modified this rule to provide relief for one almond pasteurizer; however, the source is required to fire its boiler exclusively on PUC quality natural gas. See Rule 4307 (amended May 19, 2011), section 5.1.2. See also, SJVAPCD, "Final Draft Staff Report, Proposed Amendments to Rule 4307 (Boilers, Steam Generators, and Process Heater  -  2.0 MMBtu/hr to 5.0 MMBtu/hr)," April 21, 2011
      Rule 4308 "Boilers, Steam Generators, and Process Heaters  -  0.075 MMBtu/hr to 2.0 MMBtu/hr," as revised on December 17, 2009, applies to any gaseous fuel or liquid fuel fired boiler, steam generator, or process heater with a total rated heat input greater than 0.075 MMBtu per hour but less than 2.0 MMBtu per hour. EPA approve Rule 4308 (revised December 17, 2009) as a SIP revisions (and as meeting CAA section 182(b)(1) RACT) into the SIP on January 31, 2011 at 76 FR 5276.
      Boiler subject to Rules 4307 and 4308 are too small to have the potential to emit 25 tpy or more of NOx. An uncontrolled 5.0 MMBtu gas- or liquid-fuel boiler would need to emit at a rate of 1.14 lbs of NOx per MMBtu burned to emit 25 tpy of NOx (25 tpy x 2000 lb/ton divided by 365 days per year x 24 hours per day x 5 MMBTU/hr). According to Table 4-7 in the 1994 ACT, uncontrolled NOx emissions rates for gas and liquid fuel boilers range from 0.06 lb/MMBtu to 0.79 MMBtu.
      Rule 4352 "Solid Fuel Fired Boilers, Steam Generators And Process Heaters," as revised May 18, 2006, applies to any boiler, steam generator or process heater fired on solid fuel at a source that has a potential to emit more than 10 tons per year of NOx or VOC. We approved Rule 4352 into the California SIP on October 1, 2010. In that action, we determined that the District had failed to demonstrate that the rule provided for the implementation of RACT as required by CAA section 182(b)(2); however, we also determined that rule's emissions limits were sufficiently stringent to necessitate the use of the advanced technologies required by CAA section 182(e)(3). All units subject to Rule 4352 were required to comply with the Rule's limits no later than January 1, 2007. Rule 4352, section 7.0.
      All of the NOx emission limits in the revised rule effectively require operation of Selective Noncatalytic Reduction (SNCR) control systems. We believe SNCR is "comparably effective" to SCR for the affected sources as discussed below, and thus fulfills section 182(e)(3) requirements for these affected sources. SNCR also appears to achieve NOx emission reductions comparable to combustion of clean fuels at these types of boilers. 
      According to information in the RACT/BACT/LAER Clearinghouse, recent Prevention of Significant Deterioration (PSD) permits contain emission limits for coal-fired boilers ranging from 0.067 lbs/MMBtu (for large coal-fired boilers with SCR and low-NOx burner technology) to 0.1 lbs/MMBtu (for medium-sized coal-fired boilers with SNCR). These limits reflect Best Available Control Technology (BACT) determinations under the PSD program. According to the 1994 ACT for ICI boilers (Tables 2-6), wood-fired watertube boilers with SCR can achieve NOx emissions of 0.22 lb/MMBtu. The 1994 ACT does not contain emissions levels for wood-fired FBC boilers with SCR but states that this type of unit with SNCR can achieve NOx emission limits ranging from 0.03 to 0.20 lb/MMBtu. Additionally, a permitted biomass facility in CA that operates a low temperature SCR has a similar emission limit in its permit as biomass facilities with SNCR (approximately 0.1 lbs/MMBtu).
      Our review of these emission ranges indicates that although emission rates can vary according to fuel type and boiler size, generally SNCR controls are comparably effective to SCR for boilers firing wood (biomass), MSW, and many other types of solid fuels. As a general matter, SNCR is also comparably effective to SCR control for circulating fluidized bed coal-fired boilers of less than 50 MW electric generation capacity. For coal-fired boilers, we focused our review on circulating fluidized bed boilers of less than 50 MW generation capacity because all existing coal-fired boilers in SJV are of this type and below this size. The emission levels achieved by SNCR control systems are also generally comparable to the uncontrolled NOx emissions from boilers firing clean fuels such as natural gas, which may range from 0.07 to 0.45 lb/MMBtu. 1994 ACT, Table 2.2. SNCR control systems consistently achieve up to 80 percent NOx emission reductions and are compatible with almost all solid fuel-fired boiler operations, while other controls may in some cases be sensitive to catalyst poisoning and other technical constraints. As to boilers that emit above 25 tpy of NOx, we note as a practical matter that only existing boilers in SJV are likely to be constrained by the NOx emission limits in Rule 4352, as all new boilers that potentially emit above 25 tpy and all major modifications at existing boilers will also be subject to the more stringent control technology requirements of the Nonattainment New Source Review (NNSR) or PSD permit programs. The requirements of Rule 4352 are generally applicable to this source category and do not supplant any more stringent control requirements that apply on a case-by-case basis under the NNSR or PSD permit programs. See 75 FR 60623. 
      New and modified boilers that will emit or have the potential to emit 25 tpy or more of NOx are subject to the District's new source permitting rule (Rule 2201 "New and Modified Stationary Source Review"). This rule requires new and modified source to install and operate best available control technology/lowest achievable emissions reductions technology. EPA approved Rule 2201 into the SIP at 75 FR 26102 (May 11, 2010). 
      Based on our review of the emission limitations in SJVAPCD's rules and the applicable compliance deadlines, we propose to find that the SJV Ozone SIP meets the requires of CAA section 182(e)(3).

J.  Contingency Measures
1.  Requirements for Contingency Measures
All 8-hour ozone nonattainment areas classified under subpart 2 as moderate or above must include in their SIPs contingency measures consistent with CAA sections 172(c)(9) and 182(c)(9). Contingency measures are additional controls to be implemented in the event the area fails to meet a RFP milestone or fails to attain by its attainment date. These contingency measures must be fully adopted rules or measures which are ready for implementation quickly upon failure to meet milestones or attainment. The SIP should contain trigger mechanisms for the contingency measures, specify a schedule for implementation, and indicate that the measures will be implemented without significant further action by the State or EPA See 68 FR 32802, 32837 and 70 FR 71612, 71650. Contingency measures should submitted along with the attainment demonstration which was due by June 15, 2007 for areas designated in 2004. See 70 FR 71612, 71651.
Additional guidance on the CAA contingency measure provisions is found in the General Preamble at 13510 - 13512 and 13520. The guidance indicates that states should adopt and submit contingency measures sufficient to provide a 3 percent emissions reduction from the adjusted RFP base year. EPA concludes this level of emissions reductions is generally acceptable to offset emission increases while States are correcting their SIPs. These reductions should be beyond what is needed to meet the attainment or RFP requirement. 
States may use reductions in either of VOC and NOx to meet the contingency measure requirement. General Preamble at 13520, footnote 6. States may also use a combination of VOC and NOx reductions.
EPA has also provided guidance that contingency measures could be implemented early, i.e., prior to the milestone or attainment date. Consistent this policy, States are allowed to use excess reductions from already adopted measures to meet the CAA sections 172(c)(9) and 182(c)(9) contingency measure requirements. This is because the purpose of contingency measures is to provide extra reductions that are not relied on for RFP or attainment and that will provide continued progress while the plan is being revised to fully address the failure to meet the required milestone or to attain. Nothing in the CAA precludes a State from implementing such measures before they are triggered. This approach has been approved by EPA in numerous SIPs. See 62 FR 15844 (April 3, 1997) (approval of the Indiana portion of the Chicago area 15 percent rate of progress (ROP) plan); 62 FR 66279 (December 18, 1997) (approval of the Illinois portion of the Chicago area 15 percent ROP plan); 66 FR 30811 (June 8, 2001) (proposed approval of the Rhode Island post-1996 ROP plan); and 66 FR 586 and 66 FR 634 (January 3, 2001) (approval of the Massachusetts and Connecticut 1-hour ozone attainment demonstrations). In the only adjudicated challenge to this approach, the court upheld it. See LEAN v. EPA, 382 F.3d 575 (5th Cir. 2004). 70 FR 71611, 71651.
Furthermore, states can also use federal measures that result in additional emissions reductions beyond those needed for attainment or RFP as contingency measures. EPA has approved the use of federal measures as part of contingency measures in several actions on 1-hour ozone SIPs. See 62 FR 15844 (April 3, 1997), 62 FR 66279 (December 18, 1997), 66 FR 30811 (June 8, 2001), 66 FR 586 (January 3, 2001), and 66 FR 634 (January 3, 2001).
In addition, CAA section 182(e)(5) authorizes EPA to "approve provisions of an implementation plan for an Extreme Area which anticipate development of new control techniques or improvement of existing control techniques, and an attainment demonstration based on such provisions," if the State meets certain criteria. See CAA 182(e)(5). See TSD, section II.E. Such plan provisions may include enforceable commitments to submit, at a later date, contingency measures for failure to attain under CAA section 172(c)(9), in addition to the contingency measures to be implemented if the anticipated technologies approved under section 182(e)(5) do not achieve planned reductions. These contingency measures must be submitted no later than three years before proposed implementation of the plan provisions and approved or disapproved by EPA in accordance with CAA section 110.

2.  Contingency Measures in the SJV 2007 8-Hour Ozone SIP
      The contingency measure provision is described in Section 11.6. of the 2007 Ozone Plan and Appendix D of the 2007 State Strategy as updated on February 1, 2008. California revised its contingency measure provisions in the 2011 Ozone SIP Revisions, Appendix A. 
      To provide for contingency measures for failure to make RFP, the SIP relies on surplus NOx reductions in the RFP demonstration. See 2011 Ozone SIP Revision, Attachment A, p. A-3. See also Table J-1 below and Table G-2 in this TSD.
      To provide in part for contingency measures for failure to attain, the SIP relies in part on additional incremental emissions reductions resulting from fleet turnover in the 2024. For SJV, these values are 2 tpd NOx and less than 0.5 tpd VOC. See 2011 Ozone SIP Revision Supplement, Attachment 2. CARB has submitted an enforceable commitment to submit no later than 2020, additional contingency measures under CAA section 182(e)(5) that meet the requirements for attainment contingency measures in CAA section 172(c)(9), in addition to contingency measures to be implemented if the anticipated long-term measures approved pursuant to section 182(e)(5) do not achieve planned reductions. See CARB Resolution No. 11-22 (July 21, 2011).

3.  Evaluation and Conclusions
Contingency measures for failure to make RFP - As discussed above in section II.G., we are proposing to approve the RFP demonstration. As seen in Table J-1, there are sufficient excess reductions of NOx in each milestone year to provide the 3 percent of adjusted baseline emissions reductions needed to meet the RFP contingency measure requirement.
No RFP contingency measures are needed for 2008, since the 2011 Ozone SIP Revisions demonstrate that SJV has already met its 2008 milestone. See Table 11 above. As a result, contingency measures for failure to meet the 2008 RFP benchmark will never be triggered and thus are not needed. 
Contingency measures for failure to attain  -  The incremental additional emissions reductions that will occur in 2024 (the year after the attainment year) from the continuing implementation of both on- and  - off road motor vehicle controls may be used to meet the contingency measure requirement for failure to attain. For the SJV, these reductions are 2 tpd of NOx and less than 0.5 tpd of VOC. 
Based on our proposal to determine that the State has satisfied the criteria in section 182(e)(5) for reliance on the new technologies as part of the attainment demonstration in the SJV 2007 8-Hour Ozone SIP, we propose to approve CARB's enforceable commitment to submit no later than 2020, additional contingency measures under CAA section 182(e)(5) which meet the requirements for attainment contingency measures in CAA section 172(c)(9). These contingency measures would be in addition to the contingency measures required should anticipated new technologies approved pursuant to section 182(e)(5) do not achieve planned reductions. CARB Resolution No. 11-22 (July 21, 2011).
Accordingly, we propose to approve the RFP and attainment contingency measures in the SJV 2007 Ozone SIP under CAA sections 172(c)(9) and 182(c)(9), based in part on CARB's commitment to submit by 2020 additional contingency measures meeting the requirements of CAA sections 172(c)(9) and 182(e)(5). Following the State's submittal of these additional contingency measures, EPA will approve or disapprove the provisions in accordance with CAA section 110.

K.  Motor Vehicle Emissions Budgets 
1.  Requirements for Motor Vehicle Emissions Budgets
      CAA section 176(c) requires federal actions in nonattainment and maintenance areas to conform to the SIP's goals of eliminating or reducing the severity and number of violations of the NAAQS and achieving expeditious attainment of the standards. Conformity to the SIP's goals means that such actions will not:  (1) cause or contribute to violations of a NAAQS, (2) worsen the severity of an existing violation, or (3) delay timely attainment of any NAAQS or any interim milestone.
      Actions that involve Federal Highway Administration (FHWA) or Federal Transit Administration (FTA) funding or approval are subject to the EPA's transportation conformity rule, codified at 40 CFR part 93, subpart A. Under this rule, metropolitan planning organizations (MPOs) in nonattainment and maintenance areas coordinate with state and local air quality and transportation agencies, EPA, FHWA, and FTA to demonstrate that an area's regional transportation plans (RTP) and transportation improvement programs (TIP) conform to the applicable SIP. This demonstration is typically done by showing that estimated emissions from existing and planned highway and transit systems are less than or equal to the motor vehicle emissions budgets (budgets) contained in the SIP. An attainment, maintenance, or RFP SIP should establish budgets for the attainment year, each required RFP year or last year of the maintenance plan, as appropriate. Budgets are generally established for specific years and specific pollutants or precursors. Ozone attainment and RFP plans should establish budgets for NOx and VOC. See 40 CFR § 93.102(b)(2)(i).
      Before an MPO may use budgets in a submitted SIP, EPA must first determine that the budgets are adequate or approve the budgets. Submitted budgets that have not been found to be adequate or approved may not be used in conformity determinations. In order for us to find the budgets adequate and approvable, the submittal must meet the conformity adequacy requirements of 40 CFR § 93.118(e)(4) and (5) and be approvable under all pertinent SIP requirements. To meet these requirements, the budgets must reflect all of the motor vehicle control measures contained in the attainment and RFP demonstrations. See 40 CFR § 93.118(e)(4)(v).

2.  Motor Vehicle Emissions Budgets in the SJV 2007 8-Hour Ozone SIP
      The SJV Ozone SIP as submitted in 2007 included budgets for VOC and NOx for the attainment year of 2023 and the RFP years of 2008, 2011, 2014, 2017, and 2020. See 2007 Ozone Plan, Section 9.2.3 and Appendix C and CARB Staff Report, Appendix D (updating MVEB for Madera and San Joaquin Counties).
      CARB submitted updated MVEB for the San Joaquin Valley and their documentation in Appendices A and C, respectively, of the 2011 Ozone SIP Revisions. See Tables K-1 and K-2 below. The updated MVEB are for NOx and VOC for the RFP years of 2011, 2014, 2017 and 2020 the attainment year of 2023. No budgets were included for the RFP year of 2008 because it is no longer applicable as a conformity analysis year. CARB provided additional information in the 2011 Ozone SIP Revisions supplement and in emails from Douglas Ito, CARB, to Elizabeth Adams, EPA, on August 9 and 11, 2011. Table K-2 below shows how the updated MVEBs were calculated. This calculation is described in the Appendix C of the 2011 Ozone SIP Revisions. The baseline inventories are the initial SIP on-road mobile source inventories in the Appendix C of the SJV 2007 Ozone Plan as submitted in November 2007. They continue to be based on same planning assumptions that were used in the initial 2007 Ozone Plan. 
      The MVEBs are calculated by taking these baseline inventories subtracting reductions from certain pre-Plan measures ("existing measures") and reductions from measures adopted after the Plan was adopted as well as measures and other inventory adjustments included in CARB's New Heavy Duty Diesel Truck (HDDT) Model (collectively "new measures"). The final MVEB is this resulting total rounded to the next highest tenth of a ton. 
      Existing measures are:
         * AB 1493 Green House Gas Standards (NOx and VOC)
         * On-Road Portion of the Carl Moyer Program (NOx and VOC)
         * SJVAPCD's Rule 9310  -  School Buses (NOx only)
      New measures are:
         * SJVAPCD Rule 9410 Employer Based Trip Reduction (NOx and VOC)
         * Smog Check Improvements (Low pressure evap, cutpoints, light and medium duty diesels, smoke test) (NOx and VOC)
         * Reformulated Gasoline (VOC only)
         * Heavy Duty Diesel Truck Model (NOx and VOC)
               * New HDDT inventory
               * HDDT Recession Impacts
               * HDDT In-Use Rule
               * Heavy Duty Diesel Truck (HDDT) Chip Reflash
               * HDDT Public Fleet and Solid Waste Rules
               * HDDT Idling Rules

3.  January 8, 2009 Budget Adequacy/Inadequacy Finding 
      On January 8, 2009, we notified CARB that we had found the budgets in the 2007 Ozone Plan for the RFP milestone years 2011, 2014, and 2017 adequate and the MVEBs for the RFP milestone years 2008 and 2020 and the attainment year of 2023 inadequate for transportation conformity purposes. See letter Deborah Jordan, EPA Region 9, to James Goldstene, CARB, "RE: Adequacy Status of San Joaquin Valley 8-Hour Ozone Reasonable Further Progress and Attainment Plan Motor Vehicle Emissions Budgets," January 8, 2009. We published a notice of our findings at 74 FR 4032 (January 22, 2009). This adequacy finding is also available at EPA's transportation conformity website, www.epa.gov/otaq/stateresources/transconf/pastsips.htm.
      We found the budgets for 2011, 2014 and 2017 adequate for transportation conformity decisions because they were consistent with the State's RFP demonstrations for milestone years 2011, 2014, and 2017 and were based on control measures, with one minor exception, that have already been adopted and implemented. The budgets also meet the other adequacy criteria in 40 CFR 93.118(e)(4) and (5). These budgets are currently being used by the MPOs and DOT in transportation conformity determinations. EPA's proposed approval of the revised budgets submitted in August 2011 does not affects the adequacy status of these budgets. They remain adequate for transportation conformity purposes until EPA either finds replacement budgets adequate or a final action approving replacement budgets becomes effective.
      We found the RFP budgets for 2008 inadequate for transportation conformity purposes the 2007 Ozone Plan did not show RFP for the year 2008 and thus the budget did not meet the transportation conformity rule's adequacy criteria that the budgets when considered together with all other emissions sources, are consistent with applicable requirements for RFP (40 CFR 93.118(e)(4)(iv)).
      We found the 2020 and 2023 budgets inadequate because they included estimated emission reductions associated with a number of commitments for future rule adoption that lack specificity. As such, the SJV MPOs would not have been able to accurately quantify future emission reductions associated with the commitments. Therefore, the 2020 and 2023 budgets were not precisely quantified or related to the overall emissions inventory and other measures as required by the adequacy criteria found in 40 CFR 93.118(e)(4)(iii), (iv), and (v). 

4.  Proposed Action on the Revised MVEBs
      As part of its review of the budgets' approvability, EPA has evaluated the revised budgets using our adequacy criteria in 40 CFR § 93.318(e)(4) and (5). As documented in Table K-3 below, we found that they meet each adequacy criterion. As documented in this TSD, we have completed our detailed review of the 2007 SJV 8-hour Ozone SIP and supplemental submittals including the 2011 Ozone SIP Revisions and are proposing to approve the SIP's attainment and RFP demonstrations. We have also reviewed the proposed MVEBs submitted with the 2011 Ozone SIP Revision and have found that they are consistent with the attainment and RFP demonstrations, were based on control measures that have already been adopted and implemented and meet all other applicable statutory and regulatory requirements including meeting the adequacy criteria in §93.118(e)(4) and(5). Therefore, we are proposing to approve the 2011, 2014, 2017, 2020, and 2023 MVEB as shown in Table K-1. 
      EPA is not required under its Transportation Conformity rules to find budgets adequate prior to proposing approval of them. However, we will complete the adequacy review of these budgets either prior to or concurrently with our final action on SJV 2007 8-Hour Ozone SIP. We will also post the revised budgets on EPA's adequacy review web page.
      If the proposed approval of the budgets is finalized, then the SJV MPOs and the U.S. DOT will be required to use the revised budgets in transportation conformity determinations. For these conformity determinations, the motor vehicle emissions from implementation of the transportation plan should be projected and compared to the budgets at the same level of accuracy as the budgets in the plan, for example emissions should be rounded to the rounded to the next highest tenth of a ton (e.g. 0.1 tpd). Also note that due to the nature of these budgets (combining reductions from control measures related to the in-use truck and bus rule, some of which may be included CARB's upcoming revision to the EMFAC model, EMFAC2011) the MPOs will need to show the off-model emission reductions associated with the individual control measures incorporated into the budgets, from CARB, for the appropriate analysis years in future conformity determinations so that they can include these reductions in regional emissions analysis per 40 CFR § 93.122 until EMAFAC2011 is submitted to EPA and EPA approves the model for use in SIPS and transportation conformity determinations.

CARB released the plan on May 15, 2007 and requested public comments by June 13, 2007 or at the public hearing held on June 14, 2007. 
The Plan relies on reduction from measures and commitments in the 2007 State Strategy. The November 16, 2007 transmittal letter submitting the 2007 State Strategy was sent by CARB's Executive Officer, James Goldstene, the Governor's designee. The transmittal letter indicates that CARB adopted the 2007 State Strategy for the SIP on September 27, 2007. CARB released the 2007 State Strategy on April 26, 2007 and May 7, 2007 and requested public comments by the public hearing held on September 27, 2007.
CARB updated both the SJV 2007 Ozone Plan and the 2007 State Strategy in the 2011 Ozone SIP Revisions. The July 29, 2011 transmittal letter submitting the 2011 Ozone SIP Revisions was sent by CARB's Executive Officer, James Goldstene, the Governor's designee. The transmittal letter indicates that the CARB formally adopted the SIP Revision on July 21, 2011 through a Board Resolution (11-22). CARB released the plan on June 20, 2011 and requested public comments by July 20, 2011 or at the public hearing held on July 21 2011.
Sec. 93.118(e)(4)(ii)
The plan was developed through consultation with federal, state and local agencies; full implementation plan documentation was provided and EPA's stated concerns, if any, were addressed.
                                       Y
The 2007 Ozone Plan was developed through consultation with the San Joaquin Valley interagency consultation working group (the Model Coordinating Committee). Members of the consultation group include federal, state and local agency including EPA, FHWA, FTA, CARB, Caltrans, SJVUAPCD, and each county's MPO. The 2011 Ozone SIP Revisions and its Appendices A and C which describe the revised MVEB were made available to the MPOs and other agencies for review and comment during the public comment period. EPA received a copy of the, the draft SJV 2007 Ozone Plan, draft State Strategy, draft 2009 State Strategy Update, and the draft 2011 Ozone SIP Revisions. It provided comments on the 2011 Ozone SIP Revisions. which CARB addressed. CARB also provided additional information supporting the MVEB in CARB 2011 SIP Revision supplement. Furthermore, in response to EPA's questions, CARB provided additional information via an August 10, 2011 letter sent by Lynn Terry. CARB to Deborah Jordan, EPA and emails from Doug Ito to Elizabeth Adams on August 9 and 11, 2011. The additional technical clarifications on the budgets provided in documents attached with these communications answered EPA's questions.
Sec. 93.118(e)(4)(iii)
The motor vehicle emission budgets are clearly identified and precisely quantified.
                                       Y
The revised motor vehicle emissions budgets are clearly identified and precisely quantified in Appendices A and C of the 2011 Ozone SIP Revisions and further described in Attachment A of the July 29, 2011 letter and the additional technical information provided by CARB. These budgets reflect control measures that were already adopted at the time the CARB adopted the 2011 Ozone SIP Revisions on July 21, 2011. 2011 Ozone SIP Revisions, Appendix A, p. 3. CARB did not update the MVEB for 2008 because the 2008 budgets are no longer needed for any conformity determination in the SJV. 2011 Ozone SIP Revisions, Appendix C.
Sec. 93.118(e)(4)(iv)
The motor vehicle emissions budget(s), when considered together with all other emission sources, is consistent with applicable requirements for reasonable further progress and attainment.
                                       Y
EPA has preliminarily concluded that the revised budgets for the years 2011, 2014, 2017, 2020, and 2023 when considered together with all other emission sources and controls, are consistent with the requirement to demonstrate RFP for 1997 8-hour ozone standard. This finding is based on our review of the RFP demonstration in the SJV 2007 8-Hour Ozone SIP, as revised on July 21, 2011. As documented in Section II.G. of this TSD, EPA is proposing to approve the revised RFP demonstration.
EPA has concluded that the revised budgets for the year 2023 when considered together with all other emission sources and controls are consistent with the requirement to demonstrate expeditious attainment of the 1997 8-hour ozone standard. This finding is based on our review of the updated attainment demonstrations in the SJV 2007 8-Hour Ozone SIP, as revised on July 21, 2011. As documented in Section II.F. of this TSD, EPA is proposing to approve the revised attainment demonstration.
Sec. 93.118(e)(4)(v)
The plan shows a clear relationship among the emissions budget(s), control measures and the total emissions inventory.
                                       Y
The emission inventory for all stationary, area, on-road mobile, and non-road mobile sources, and their relation to control measures and the reductions from existing measures are described in Attachment A of CARB's Resolution 07-28 dated September 27, 2007 adopting the 2007 State Strategy. The reductions from individual existing measures used in the budgets are also described in more detail in Tables B-1 and B-2 in Appendix B and in Table C.9 in Appendix C to the SJV 2007 Ozone Plan as well as in the 2011 Ozone SIP Revisions Supplement, and additional technical information transmitted from CARB in their August 10 letter and emails on August 9th and 11[th].
Sec. 93.118(e)(4)(vi)
Revisions to previously submitted control strategy or maintenance plans explain and document any changes to any previous submitted budgets and control measures; impacts on point and area source emissions; any changes to established safety margins (see § 93.101 for definition), and reasons for the changes (including the basis for any changes to emission factors or estimates of vehicle miles traveled).
                                       Y
Prior to submittal of the 2007 Ozone Plan, the most recent ozone SIP for the SJV nonattainment area was the SJV 2004 1-Hour Ozone Plan. EPA found the budgets from the 2004 SJV 1-Hour Ozone Plan to adequate in 2005 (70 FR 7734, February 15, 2005). The motor vehicle emission inventories in the 2004 1-hour ozone SIP are based on the EMFAC2002 motor vehicle emissions model, and motor vehicle emission inventories in the SJV 2007 Ozone Plan and subsequent updates were prepared using the most recent version of the model, EMFAC2007. EMFAC2007 was approved by EPA for use in SIPs and conformity determinations on January 18, 2008 (73 FR 3464). This notice approving EMFAC2007 details the basis for the changes to the emission factors. 
The MVEB being reviewed here are for the 8-hour ozone standard and do not constitute a revision to the MVEB previously submitted in the 2004 Ozone Plan because that Plan addressed different ozone standards.
CARB submitted revisions to the motor vehicle emission budgets in the SJV 2007 Ozone Plan as part of the 2011 Ozone SIP Revisions. The revisions removed some control measures that were included in the prior RFP and attainment budgets (e.g. SJV's Indirect Source Rule), included revisions to the Heavy Duty Diesel Truck inventory using CARB's Heavy Duty Truck Model and adjusted the reductions associated with smog check and SJV Rule 9310 to reflect updated VMT data from the SJV MPOs. Emission reductions associated with the SJV Trip Reduction Rule were also adjusted to reflect actual reductions.
Sec. 93.118(e)(5)
EPA has reviewed the State's compilation of public comments and response to comments that are required to be submitted with any implementation plan.
                                       Y
The 2007 Ozone Plan contains public comments and the District's responses in appendices G and L. Specifically, appendix G includes comments and responses from the District's series of Town Hall meetings held from July 26-28, 2006. Appendix L includes comments and responses from the District's public workshops and public comment periods on the draft 2007 Ozone Plan. Additional verbal comments were received during the adoption public hearings held by the District and CARB and are also included as attachments to the November 2007 SIP submittal. EPA provided comments on the 2011 Ozone SIP Revisions but CARB received no other comments. We have reviewed the compilation of comments and responses and find the responses to be acceptable. No issues that might have affected our adequacy finding remain unanswered.

L.  Status of Other Clean Air Act Requirements Applicable to Extreme Ozone Nonattainment Areas
In addition to the requirements discussed above, title 1, subpart D of the CAA includes other provisions applicable to extreme ozone nonattainment areas, such as the San Joaquin Valley. We briefly describe these provisions and their current status below for informational purposes only.

1.  Enhanced Vehicle Inspection and Maintenance Programs
CAA section 182(c)(3) requires states with ozone nonattainment areas classified under subpart 2 as serious or above to implement an enhanced motor vehicle inspection and maintenance (I/M) program in those areas. The requirements for those programs are provided in section 182(c)(3) and 40 CFR § 51.351.
On July 1, 2010 at 75 FR 38023, EPA approved California's inspection and maintenance program in the San Joaquin Valley as meeting the requirements of the CAA and applicable EPA regulations for enhanced I/M programs.

2.  Reformulated Gasoline Program
      As an extreme ozone nonattainment area for the 1-hour ozone standard, the San Joaquin Valley was covered under the federal reformulated gasoline (RFG) program. See CAA section 211(k)(10)(D). As an 8-hour ozone nonattainment area, SJV continues to be covered under the federal RFG program. See 40 CFR § 80.70(m)(1)(i) and 70 FR 71685. California has its own RFG program (California Phase III RFG (CaRFG3)), which also applies in the SJV. EPA approved CaRFG3 program into the California SIP on May 12, 2010. See 75 FR 26633.

3.  New Source Review Rule
CAA section 182(a)(2)(C) requires states to develop SIP revisions containing permit programs for each of its ozone nonattainment areas. The SIP revisions are to include requirements for permits in accordance with CAA section 172(c)(5) and 173 for the construction and operation of each new or modified major stationary source (with respect to ozone) anywhere in the nonattainment area. See also CAA section 182(e). EPA's implementation regulations for nonattainment new source review (NSR) programs are in 40 CFR § 51.165, and guidance specific to ozone nonattainment areas is provided in the preamble to the 8-hour ozone implementation rule. See 70 FR 71612 at 71671-71684.
EPA approved the SJVAPCD's new source review rules, Rules 2201 "New and Modified Stationary Source Review" and Rule 2020 "Exemptions," into the SJV portion of the California SIP and found that they had been adequately amended to reflect extreme area requirements. See 75 FR 26102 (May 11, 2010). 

4.  Clean-Fuel Vehicle Program
CAA sections 182(c)(4)(A) and 246 requires California to submit for EPA approval a SIP revision that includes measures to implement the Clean Fuel Fleet Program. CAA section 182(c)(4)(B) allows states to "opt-out" of the clean-fuel vehicle fleet program by submitting a SIP revision consisting of a program or programs that will result in at least equivalent long term reductions in ozone-producing and toxic air emissions.
In 1994, CARB submitted a SIP revision to opt-out of the federal clean fuel fleet program This SIP revision demonstrated that is California's low-emissions vehicle program achieved emission reductions at least as large as the federal program would. EPA approved the State's opt-out on August 27, 1999. See 64 FR 46849.

5.  Gasoline Vapor Recovery
CAA section 182(b)(3) mandates that states submit a revised SIP by November 15, 1992 that requires owners or operators of gasoline dispensing systems to install and operate gasoline vehicle refueling vapor recovery ("Stage II") systems in ozone nonattainment areas classified as moderate and above. California's ozone nonattainment areas had implemented Stage II vapor recovery well before the passage of the CAA Amendments of 1990. See General Preamble at 13514.
Under California State law (Health and Safety Code Sections 41954), CARB is required to adopt procedures and performance standards for controlling gasoline emissions from gasoline marketing operations, including transfer and storage operations. State law also authorizes CARB, in cooperation with districts, to certify vapor recovery systems, to identify defective equipment, and to develop test methods. CARB has adopted numerous revisions to its vapor recovery program regulations. See Table A-7 in Appendix A to this TSD. See also CARB's website, http://www.evrhome.org/
In the San Joaquin Valley, the installation and operation of CARB-certified vapor recovery equipment is required and enforced by SJVUAPCD Rules 4621 and 4622, the latest versions of which were approved by into the SIP on October 30, 2009. See 74 FR 56120.

6.  Enhanced Ambient Air Quality Monitoring
CAA Section 182(c)(1) requires that all ozone nonattainment areas classified as serious or above implement measures to enhance and improve monitoring for ambient concentrations of ozone, NOx, and VOC, and to improve monitoring of emissions of NOx and VOC. 
The SJVAPCD's Annual Air Quality Monitoring Network Plan (June 30, 2010) describes the steps the State has taken to address the requirements of CAA section 182(c)(1). The SJV's Photochemical Assessment Monitoring Station (PAMS) network consists of six sites operated by SJVAPCD centered around Fresno and Bakersfield. These sites are described on pages 13 and 17 of the monitoring network plan. EPA has approved the SJVAPCD PAMS network. See letter, Matthew Lakin, EPA Region 9 to Scott Nester, SJVAPCD, November 1, 2010.

7.  CAA Section 185 Fee Program
CAA section 185 requires that the SIP for each severe and extreme ozone nonattainment area provide that, if the area fails to attain by its applicable attainment date, each major stationary source of VOC and NOx located in the area shall pay a fee to the State as a penalty for such failure for each calendar year beginning after the attainment date, until the area is redesignated as an attainment area for ozone. States are not yet required to implement CAA section 185 fee programs for the 1997 8-hour ozone standard.

                                       
                                       
                                       
                                       
                                       
                                       
                                       
                                       
                         Appendix A  -  State Measures

A.  Complete List of State Measures
      Appendix Table A-1 is a list of all measures adopted by CARB from 1990 until the end of 2006. This period covers the 18 years prior to the development of the 2007 State Strategy and the SJV 2007 Ozone Plan. The table should include any substantive rules that would still be generating emissions reductions in the San Joaquin Valley during the 2005-2024 time period covered by the SJV 2007 8-Hour Ozone SIP and thus reflected in the baseline for the SIP.
      This list does not include the limits on pesticide emissions adopted by the California Department of Pesticide Regulation nor the State's inspection and maintenance program adopted by the California Bureau of Automotive Repair.
      Measures that are categorized as Not Applicable are either solely administrative (e.g., permit fees, state ambient air quality standards), do not address VOC or NOx in the SJV (e.g., asbestos air toxic control measure), or otherwise do not affect emissions in the SJV (e.g., test methods).

B. State Rules that Do Not Address VOC or NOx in the San Joaquin Valley

      A substantial number of the measures adopted by CARB since 1990 do not affect VOC or NOx emissions in the San Joaquin Valley. These types of measures include fee rules, identification of toxic air contaminants, area boundary designations, and controls for pollutants other than VOC or NOx. Appendix Table A-2 provides a list of these measures.

F. State Vapor Recovery Measures

      Under California State law (Health and Safety Code Sections 41954), CARB is required to adopt procedures and performance standards for controlling gasoline emissions from gasoline marketing operations, including transfer and storage operations. State law also authorizes CARB, in cooperation with the districts, to certify vapor recovery systems, identify defective equipment, and develop test methods. The installation and operation of CARB-certified vapor recovery equipment is required and enforced by SJVAPCD Rules 4621 and 4622. Appendix Table A-7 is a list of rulemaking actions taken by CARB since 1990 that address vapor recovery equipment certification, defects, and/or test methods.
