### Foreword

The Air Resources Board (ARB or Board) adopted the 2007 State Strategy in September 2007 as a revision to the California Stat e Implementation Plan (SIP). Since then, three major things have occurred. First, ARB has adopted comprehensive measures to implement the 2007 State Strategy. Sec ond, in December 2008, ARB adopted the Scoping Plan mandated by AB 32, the Cal ifornia Global Warming Solutions Act of 2006. Actions outlined in the Scoping Plan will help reduce ozone and particulate pollution over the ozone attainment timeline of the SIP. Third, the nature of our national and State economies is shifting, and as a result, A RB expects California’s economy to be greener in the future.

California’s SIP relies on advanced technologies to be developed between now and

2023 to achieve the last increment of emission redu ctions needed for ozone attainment. With the State’s focus on climate change and the co mpletion of the Scoping Plan, there is now an opportunity to speed progress by linking our SIP efforts with our climate change efforts. In particular, ARB staff is workin g to align the SIP’s new technology needs with the State’s actions to reduce greenhouse gases. California’s actions to reduce greenhouse gas emissions will help transitio n the State to new technologies, improved energy efficiency across the economy, and better land use patterns that are also necessary to meet air quality standards and ot her public health goals. The additional benefits of these actions are significan t and will increase with further

reductions in fossil fuel combustion.

The 2007 State Strategy was based on the best assum ptions about California’s future available at the time, assumptions about the nature of economic growth, the availability of incentive funds, land use and transportation pat terns, technology advancement, and more. All of these factors continue to change. Re sponding to these changes is part of our ongoing evaluation of SIP implementation. Over the next years, as ARB completes implementation of the SIP, staff will be looking at these changes and their implications to the State’s air quality program. Frequent updat es to the SIP will be needed to incorporate new data into the SIP’s technical found ation and to map out the next round

of emission reduction measures.1



### Part One: Status Report Status of Implementation

In September 2007, ARB adopted the 2007 State Strat egy for the California SIP. In doing so, the Board set out how the State will achi eve the needed emission reductions from cars, trucks, locomotives, consumer products, and more to meet health-based federal air quality standards. This report documen ts that progress in terms of actions taken by ARB and emission reductions achieved in im plementing the SIP.

ARB is on track in implementing the 2007 State Stra tegy. In 2007 and 2008, ARB adopted 14 pollution-reducing regulations to implem ent the SIP. Eleven of these regulations implement 10 of the new measures identi fied in the 2007 State Strategy. Three additional measures were adopted that were no t envisioned in the 2007 State Strategy but will help California meet the commitme nts in the 2007 State Strategy.

The most significant of the rules adopted to implem ent the 2007 State Strategy is the cleaner in-use heavy-duty diesel truck rule adopted in December 2008. This rule represents a multi-year effort and is our most aggr essive undertaking yet to turn over the legacy fleet of engines and replace them with t he cleanest technology available. It pushes the cleanup of diesel engines beyond what ha s ever been done before in the country.

The in-use truck rule will accelerate the introduct ion of newer, cleaner truck and bus engines in California – by 2023 all of the heavy-du ty trucks and buses in California will be 2010 model year or newer (the cleanest available ). The chart below illustrates the accelerated phase-in of newer, cleaner trucks to th e entire California fleet.

newer

2014 23% 22% 55%

2020 5% 9% 87%

2023 0% 0% 100%

The truck measure in the 2007 State Strategy envisi oned modernizing truck fleets operating in California to the equivalent of the cl eanest adopted new engine (2010) standards. The adopted regulation meets that goal at the pace necessary to meet all the SIP target dates. The adopted regulation meets or exceeds the combined NOx and PM2.5 SIP fleet rule targets in both the South Coas t and San Joaquin Valley for all years. In 2014, in the South Coast, the SIP target is met with slightly more PM2.5 reductions and slightly less NOx than expected. Th e PM2.5 modeling used in the South

Coast Air District SIP shows that direct PM2.5 emis sion reductions are relatively more effective in reducing ambient particulate levels th an are NOx reductions. The rule achieves 60 tons per day of NOx in 2014 plus the eq uivalent of six more tons per day of

NOx that come from extra PM2.5 reductions.2

The table below summarizes the progress made from 2 002 emission levels (the baseline for the SIP inventory) for NOx reductions, the key pollutant that must be

reduced for both PM2.5 and ozone attainment. It re presents recent rules adopted at the state level and, for the South Coast in 2014, recen t rules adopted at the local level. The majority of the reductions achieved to date have co me from statewide mobile source strategies.

With its actions since adopting the State Strategy in September 2007, California now has in place programs and regulations that will ach ieve 95 percent of the NOx

reductions needed to meet the PM2.5 standard in the San Joaquin Valley and 87 percent of the reductions needed for PM2.5 attai nment in the South Coast. California has also achieved 93 percent of the redu ctions needed from near-term measures for ozone attainment in the San Joaquin Va lley and 90 percent of the

reductions needed in the South Coast. Additional r eductions are still needed from longterm measures. These reductions are not included i n the following table.

than 2002 levels. Note: The percent progress numbers include reductio ns from the current program and recently adopted measures.

In addition to reporting on the status of ARB’s eff orts to implement the 2007 State Strategy, this report includes proposed technical a mendments to the SIP that the U.S. Environmental Protection Agency (U.S. EPA) has asked ARB to make to aid U.S. EPA’s approval of the SIP. The amendments acc ount for reductions achieved since adoption of the 2007 State Strategy, clarify ARB’s legal commitments in light of U.S. EPA’s approval criteria, and extend the descri ption of the long-term strategy for identifying future technologies to achieve the last increment of reductions. These amendments do not change the emission reducti ons in tons per day of NOx, reactive organic gases (ROG), oxides of sulfur (SOx ), and direct PM2.5 that the Board committed to achieve by specific years when it adop ted the 2007 State Strategy.

The amendments also include the commitment for emis sion reductions in the
Sacramento area that the Board will consider at its March 2009 meeting along with3

approval of the SIP for the Sacramento area. The r eductions in Sacramento from the statewide measures in the 2007 State Strategy had n ot been quantified at the time the 2007 State Strategy was adopted and so are not refl ected in the 2007 State Strategy. For clarity, staff is now proposing to reflect this commitment within the State Strategy.

ARB is also implementing its 2006 Emission Reduction Plan for Ports and Goods

Movement

. This plan outlines strategies to reverse the gro wth in goods movementrelated emissions and reduce risk from exposure to diesel particulate emissions. Most of the strategies in the plan are also measures in the 2007 State Strategy and the regulations adopted in 2007 and 2008 that reduce PM 2.5 emissions implement both of these plans.

In addition to adopting regulations that reduce ozo ne- and PM2.5-forming emissions, ARB has been busy developing a scoping plan that ou tlines how California will meet its aggressive greenhouse gas emission reduction goals. ARB adopted the Scoping Plan in December 2008. While the Scoping Plan targets c limate change emissions, many of the measures in the Scoping Plan will achieve ozone and PM2.5 co-benefits. Staff is in the process of calculating those regional co-benefi ts for years critical to the SIP. Staff will include those estimates in future status repor ts.4



### Recent ARB Rulemakings--2007 and 2008

The following table summarizes the 10 measures that were identified in the 2007 State Strategy for which ARB has adopted implementing rul es. In total, this represents 11 separate rulemakings. The column labeled Schedule Adoption Year was the year ARB targeted in the SIP for action. The column nex t to that is the year that the Board adopted the implementing rule.

emission reduction tables to follow.

ARB has also adopted the three rules in the followi ng table that will achieve ozone and PM2.5 precursor reductions that were not identified as specific measures at the time the 2007 State Strategy was adopted. Although not call ed out in the SIP, these rules will help clean the air and ARB will credit any reductio ns achieved toward fulfillment of ARB’s commitment to reduce emissions by specified a mounts in specific years.

### Staff Reports for Recently Adopted ARB Rules

For each of the rulemakings discussed in this repor t, ARB staff has developed and published extensive documentation. This documentat ion includes formal staff reports and the materials required for rule adoption under the Administrative Procedures Act, as well as factsheets and workshop presentations. Alt ogether, this information describes in detail the rule structure as well as the method, data, and results of the emission

reduction benefit calculations. Below are links to this detailed information.

### Analysis of Environmental Impacts

This report includes proposed technical amendments to the SIP that U.S. EPA has asked ARB to make to aid U.S. EPA’s approval of the SIP. ARB staff has concluded that the proposed amendments to the SIP will not re sult in any significant adverse environmental impacts, for the following reasons.

The proposed SIP amendments quantify the reductions that have been achieved since adoption of the 2007 State Strategy, clarify ARB’s legal commitments in light of U.S. EPA’s approval criteria, and extend the descri ption of the long-term strategy for identifying future technologies to achieve the last increment of reductions. The proposed amendments do not change the amount of NOx , ROG, SOx, and direct PM2.5

emission reductions that the Board committed to ach ieve by specific years when it adopted the 2007 State Strategy.

The amendments also include the commitment for emis sion reductions in the Sacramento area, since Sactamento’s attainment plan will be considered by the Board at its March 26, 2009 meeting when it considers app roval of the SIP for the Sacramento

area. The reductions in Sacramento from the statew ide measures in the 2007 State Strategy had not been quantified at the time the 20 07 State Strategy was adopted and so were not reflected in the 2007 State Strategy. For clarity, staff is now proposing to amend the State Strategy to reflect this commitment

.

ARB prepared an environmental analysis for the 2007 State Strategy prior to its approval by the Board in September 2007. Various m easures identified in the 2007 State Strategy have been adopted by the Board since that time, and separate, additional environmental analyses were also prepare d by ARB prior to the adoption of each of these measures. As discussed above, the pr oposed SIP revision simply quantifies the emission reductions that have been a chieved by these already-adopted measures, and no changes have been made to the unde rlying commitments in the 2007 State Strategy to achieve specified emission r eductions by specific dates. Therefore, staff has concluded that the proposed SI P amendments will not result in any significant adverse environmental impacts.11



### Part Two: Technical Revision to the 2007 State Strategy

The following pages completely replace the correspo nding sections in the April 26, 2007 Revised Draft Air Resources Board’s Proposed State Strategy for California’s 2007 State Implementation Plan . This revision includes the clarifying changes re quested by U.S. EPA to aid U.S. EPA approval and it quantifies the emission reductions from the State Strategy in Sacramento. It also includes the changes and additions made by the Board to the April 2007 draft when it adopted the S tate Strategy related to its

commitments to reduce emissions contained in Attach ment B to resolution 07-08. Specifically, the following replaces all material i n the April 2007 draft document starting on page 58 with the heading “State Implementation P lan Commitments” up to but not including on page 67 the section titled, “Role of F unding and Incentives Programs.”

U. S. EPA's Approval Criteria for SIPs that Rely on Enforceable Commitments to

Achieve Emission Reductions

U.S. EPA has identified three criteria which SIPs t hat rely on enforceable commitments for emission reductions need to meet to be approvab le. The first criterion is that the commitment be for a limited portion of the needed e mission reductions. Most of the

emission reductions needed for attainment in the So uth Coast and San Joaquin Valley will come from already adopted SIP measures. Conse quently, the commitments for reductions from new measures are a limited portion of the total needed. Further, the

tables in the section titled Commitment to Reduce E missions show the State's success already in fulfilling its commitment for emission r eductions. ARB has already adopted regulations that will provide a majority of the emi ssion reductions associated with proposed new measures in the 2007 State Strategy. As a result, what’s left to achieve out of the commitment is now only 51 tpd NOx, 28 tp d ROG, in the South Coast; and 7 tpd NOx, 12 tpd ROG, in the San Joaquin Valley in 2 014.

U.S. EPA's second approval criterion is that the st ate is capable of fulfilling its commitment. ARB's performance in meeting its oblig ations both under this SIP and prior SIPs is solid evidence that the State is capa ble of adopting the regulations to

which it commits. The list of ARB SIP Control Meas ures (1994-2006) on page 38 of the State Strategy also shows the State's record of con tinuous accomplishment in developing, adopting, and implementing successfully a wide range of ambitious,

innovative controls to which the State committed in prior SIPs. ARB has experienced staff and other resources needed to complete the ta sks associated with development of controls to achieve the relatively small remaining near-term measure reductions, and ARB reiterates its determination to continue expedi tious development of these

measures.

U.S. EPA's third approval criterion is that the com mitment be for a reasonable and appropriate period of time. ARB has committed to a schedule of bringing the proposed new SIP measures to the board for rulemaking consid eration. The schedule calls for four of the five remaining ARB measures to be prese nted this year or the following year. Given the variety of difficult issues to address in the complex process of regulatory12

development, this is an expeditious schedule. The fifth measure, Consumer Products Program II, is scheduled for board consideration in 2010-2012. This follows intensive efforts by ARB resulting in successful adoption on June 26, 2008 of new or more stringent regulations for more than 20 product cate gories and further product categories

in November 2008. Because of the need to collect d ata on product formulation and use, to review control options for the challenging categ ories that remain, and to resolve complex issues relating to product performance, thi s schedule is expeditious.

The seventh measure, Accelerated Introduction of Cl eaner Line-haul Locomotives, is dependant on U.S. EPA adopting Tier 4 standards for locomotive engines. Now that the new standards are adopted, ARB commits to working w ith the railroad companies to accelerate cleanup of the locomotive fleet.

ARB is also working with the Bureau of Automotive R epair (BAR) to develop and institute successfully the Smog Check program enhan cements. BAR progress to date

includes the addition of diesel vehicles to the ins pection program through state legislation (AB 1488, 2007) and authority to conduc t visible smoke tests (AB 1870, 2006). BAR regulations in progress will increase the stringency of the tests by setting lower cut points used to determine if th e vehicle initially passes or fails the Smog Check test.

Inasmuch as reductions from the enforceable commitm ent for emission reductions are not relied upon in meeting the reasonable further p rogress provisions for any area, the adoption and implementation schedule to fulfill the commitment will not jeopardize attainment. Further, the State Strategy includes a n enforceable commitment to achieve all reductions needed for attainment by the attainm ent year applicable to each area.

State Implementation Plan Commitments

This section sets forth the State’s SIP commitments for the 2007 State Strategy for the areas that need the emission benefits from the prop osed, new State measures to demonstrate attainment – the South Coast Air Basin, the San Joaquin Valley, the Coachella Valley, and the Sacramento Metro Area.

The State’s SIP commitments consist of three compon ents:

1. A commitment to achieve aggregate emission reduc tions by specific dates; 2. A commitment to propose defined new SIP measures ; and 3. A long-term strategy commitment.

The total emission reductions and the obligation to propose specific measures for Board consideration would become enforceable upon approva l by U.S. EPA of the State Strategy and each district’s attainment plan. The commitments for NOx, ROG and PM2.5 emission reductions are calculated using the summer planning inventory described in Appendix A to the Proposed State Strat egy and progress will be tracked using the same inventory to assess compliance. How ever, the PM2.5 standard is an13

annual average standard; thus the PM2.5 attainment demonstration for the South Coast was based on the corresponding annual average emiss ion reductions. Since the

emission reductions in this document and the emissi on reductions found in the PM2.5

attainment demonstration are based on different sea sonal inventories, the specific emission reduction numbers may differ.

Air quality modeling indicates that the combined em ission reductions committed to by the ARB and the South Coast and San Joaquin Valley air districts will result in attainment of the federal 8-hour ozone standard by 2023 in each of these areas, and for federal PM2.5 standard in the South Coast by the 20 14 deadline. The total emission reductions from the new measures necessary to attai n the federal standards are an

enforceable State commitment in the SIP. While the State Strategy includes estimates

of the emission reductions from each of the individ ual new measures, it is important to note that the commitment of the State Strategy is t o achieve the aggregate emission reductions identified from the existing strategy an d the adopted State Strategy. Therefore, if a particular measure does not get its expected emission reductions, the State still commits to achieving the total aggregat e 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 that exceed the projections reflected in the emission in ventories and the State Strategy, the actual emission decreases may be counted toward mee ting ARB’s total emission

reduction commitments.14

Commitment to Reduce Emissions

The tables below describe the emission reduction co mmitment proposal for Board approval. ARB staff proposes to commit to achieve the emission reductions set forth in these tables, by the dates indicated in the table e ntitled, “Schedule for Board Consideration of Proposed ARB Rulemaking” that occu rs later in this document. The reductions may be achieved through a combination of actions, including regulations, incentives, and other enforceable mechanisms.

Commitments to Secure Additional Emission Reduction s to Help Meet the South Coast District’s PM2.5 Emission Reduction Target

ARB commits to working with the South Coast Air Qua lity Management District (District) to secure funding for the District to achieve 6 tpd of NOx emission reductions from portrelated and other sources and from Metrolink trains , and to backstop the District’s 6 tpd emission reduction commitment. “Backstop” means th at ARB commits to secure some or all of the 6 tpd of the District’s emission redu ction commitment if the District fails to

achieve the emission reductions.

ARB’s emission reduction commitments may be achieve d through a combination of actions including but not limited to the implementa tion of control measures; the expenditure of local, State or federal incentive fu nds; or through other enforceable measures. In addition, ARB may meet its emission re duction commitments by securing ROG, SOx, or direct PM2.5 emission reductions inste ad of NOx reductions, if these reductions achieve the equivalent air quality benef it. In determining equivalency, the State will rely on the information on air quality m odeling documented in the South Coast

District’s SIP.21

Finally, if actual emission decreases occur in the South Coast Air Basin that are greater than the projected emissions reductions from the ad opted measures in the State Strategy, the actual emission decreases may be coun ted toward meeting ARB’s total

emission reduction commitments.

If U.S. EPA makes a finding under section 179(c)(1) of the Clean Air Act that the South Coast Air Basin has attained the Annual Average PM2 .5 National Ambient Air Quality

Standard before the entire commitment has been achi eved, ARB commits to achieving the remaining emission reductions, but they may be achieved after 2014 but no later

than 2017.

Commitments for Remaining New SIP Measures

ARB staff commits to report to the Board annually o n progress in developing, adopting, and implementing the near-term and long-term measur es in the State Strategy for California's 2007 State Implementation Plan.

ARB commits to revise the 2007 SIP as may be approp riate in a 2010 Mid-course Review SIP update to:

(a) reflect the emission benefits of newly adopted regulations; (b) to provide more detail on the State's intended actions to fulfill the commitment to achieve emission reductions in total by specific da tes; (c) to update as necessary the emissions inventorie s, including the on-road mobile source emissions inventory and motor vehicle activi ty levels for federal ozone and PM2.5 nonattainment areas; and (d) to revise as necessary other plan aspects, incl uding motor vehicle emissions budgets.

ARB commits to develop and adopt any necessary and appropriate update and submit it to U.S. EPA as a SIP revision by June 30, 2010.25

Commitment to Reduce Emissions via Long-Term Strate gy

Consistent with section 182(e)(5) of the federal Cl ean Air Act, this SIP includes long-term commitments to achieve the last increment of emission reductions necessary to meet attainment goals in the South Coast and San Joaquin Valley. As the State agency charged with ensuring California’s SIP compl iance, ARB is ultimately responsible for ensuring the necessary measures are identified no later than 2020 (three years prior to the attainment year) and the emission reductions achieved by

2023.

After adoption of the State Strategy, ARB staff pro poses to initiate a coordinated government, private, and public effort to establish emission goals for critical mobile and stationary emission source categories. Following t he setting of emission goals, ARB will start an ongoing public process to assess technolog y advancement opportunities for the critical categories. ARB staff will periodically b rief the Board at public meetings on emerging emission reduction opportunities, promisin g technologies, and the progress made in developing long-term emission reduction mea sures. As ARB staff identifies feasible technology-forcing emission reduction meas ures, staff will propose those

measures to the Board for inclusion into the SIP.

U.S. EPA, along with ARB, the South Coast and San J oaquin Valley Air Districts and the California Environmental Protection Agency, sig ned a memorandum of agreement (MOA) to commit to developing and testing new sustainable technologies to accelerate progress in meeting current and future n ational air quality standards.

The goal of the MOA is to improve air quality by al igning agency research resources, where possible and appropriate, to evaluate innovat ive technologies that have the potential to reduce emissions of pollutants and pol lutant precursors, and to develop and assess new monitoring equipment that could improve the measurement of emissions from mobile and stationary sources of pollution.

As part of this agreement, the agencies intend to c oordinate research efforts with other public and private stakeholders, including other fe deral departments and agencies and other state and local entities, in order to utilize the resources and capacities of a wide sector of government and the business community in projects to develop, demonstrate and assess new technologies that can help achieve c lean air goals.

To implement the agreement, each agency may appoint a liaison to serve as an ongoing point of contact and to, among other things , coordinate the objectives of the MOA and pursue necessary resources. The agencies a lso agreed to establish a Clean Air Technology Working Group, to administer the MOA . Projects and activities may

include:

• Creation of a Research Coordination Council to revi ew current information and explore opportunities to develop and deploy new technologies;26

• Exchange of information on research and development program plans and projects and new technologies;

• Collaborative planning and execution of research an d development programs;

• Participation of scientists, engineers, analysts an d other specialists from each agency in agreed upon activities;

• Organization of seminars and other meetings;

• Joint projects; and

• Dissemination of information to stakeholders on pot ential applications of new technologies.

No later than 2020, ARB and the two air districts w ill prepare a revision to the 8-hour Ozone SIP that (1) reflects any modifications to th e 2023 emission reduction target based on updated science, and (2) identifies any ad ditional strategies, including the implementing agencies, needed to achieve the necess ary emissions reductions by 2023. In accordance with section 182(e)(5)(B) of t he Clean Air Act, ARB will submit enforceable commitments to develop and adopt contin gency measures if the advanced technology measures do not achieve planned reductio ns.

South Coast: After accounting for the anticipated benefits of b oth adopted and new defined State and local measures, the State Strateg y demonstrates a need for another 281 tpd ROG and NOx reductions from long-term measu res. This represents 24 percent of the total reductions needed by 2023. We believe that this gap can be bridged through a cooperative effort by the local, State and federal agencies responsible for specific emission sources. This ef fort should focus on how to most effectively achieve the additional reductions, cons idering the availability and cost of potential controls.

San Joaquin Valley: After accounting for the anticipated benefits of b oth adopted and new defined State and local measures, the State Str ategy demonstrates a need for another 81 tpd NOx reductions from long-term measur es. This represents 13 percent of the total NOx and ROG reductions needed by 2023. W e believe that this gap can be bridged through a cooperative effort by the local, State and federal agencies responsible for specific emission sources. This ef fort should focus on how to most effectively achieve the additional reductions, cons idering the availability and cost of potential controls.

To implement the Long-term Strategy, ARB:

a) commits to share the results of its efforts and others to identify emerging emission reduction opportunities, promising technol ogies, and the progress made in developing long-term emission reduction measures with the public through27

periodic briefings to the Board, workshops, confere nces, symposia, website postings, and other means; b) commits to work to secure resources in the futur e for continuing research and development of new technologies; and c) commits to develop schedules for moving from con trol technology research to implementation.

Withdrawal of Chapter 4

Chapter 4 was included in ARB’s submission for hist orical purposes. It does not reflect the final decisions made regarding the South Coast air district’s attainment demonstration approved by ARB. Chapter 4 is withdr awn.
