WHEREAS, the Legislature in Health and Safety Code section 39602 has designated the State Air Resources Board (ARB or Board) as the air pollution control agencyfor all purposes setforth in federal law; WHEREAS, ARB is responsible for preparing the State Implementation Plan (SIP) for attaining and maintaining the NationalAmbientAir Quality Standards (NAAQS) as required bythe federal Clean AirAct (the Act) (42 U.S.C. section 7401 et seq.),and to this end is directed by Health and Safety Code section 39602 to coordinate the activities ofall local and regional air pollution .control and air quality managementdistricts (districts) necessaryto complywith theAct; WHEREAS, section 41650 ofthe Health and Safety Code requires ARB to approve the nonattainment plan adopted by a district as part ofthe SIP unlessthe Board finds, after a public hearing, thatthe plan does not meetthe requirements ofthe Act; WHEREAS, ARB has responsibility for ensuring thatthe districts meettheir responsibilities underthe Act pursuantto sections 39002, 39500, 39602, and 41650 of the Health and Safety Code; WHEREAS, ARB is authorized by section 39600 ofthe Health and Safety Code to do such acts as may be necessaryforthe proper execution of its powers and duties; WHEREAS, sections 39515 and 39516 ofthe Health and Safety Code provide that any duty may be delegated to the Board's Executive Officer as the Board deems appropriate; WHEREAS, the districts have primary responsibility for controlling air pollution from nonvehicularsources and for adopting control measures, rules, and regulations to attain the NAAQSwithin their boundaries pursuantto sections 39002, 40000, 40001, 40701, 40702, and 41650 ofthe Health and Safety Code; WHEREAS, the San Joaquin Valley Air Basin includes Fresno, Kings, Madera, Merced, San Joaquin, Stanislaus, Tulare, and western Kern Counties;Resolution 13-2 

### 2 WHEREAS, in July 1997, the United States Environmental Protection Agency (U.S. EPA) promulgated 24-hourand annual NAAQS forfine particulate matter (PM2.5) of65 ug/m3 and 15 ug/m3, respectively; WHEREAS, in April 2005, U.S. EPA designated the San Joaquin ValleyAir Basin as nonattainmentfor both the 65 ug/m3 and 15 ug/m3 PM2.5 NAAQS; WHEREAS, in 2008, the San Joaquin ValleyAir Pollution Control District (District) and ARB adopted a PM2.5 SIP (2008 PM2.5 Plan) to address the 65 ug/m3 24-hour PM2.5 NAAQS and transmitted it to U.S. EPA; WHEREAS, on November 9, 2011, U.S. EPA approved all elements ofthe 2008 PM2.5 Plan exceptforthe contingency measures; WHEREAS, the Act requires U.S. EPAto review existing NAAQS everyfive years and promulgate new standards as may be appropriate; WHEREAS, in December2006, U.S. EPA lowered the 24-hour PM2.5 NAAQSfrom 65 ug/m3 to 35 ug/m3; WHEREAS, effective December 14, 2009, U.S. EPAdesignated the San Joaquin Valley Air Basin as nonattainmentforthe 35 ug/m3 PM2.5NAAQS; WHEREAS, in March 2007, U.S. EPAfinalized the PM2.5 implementation rule (Rule) which established the framework and requirements that states must meet in developing PM2.5 SIPs; WHEREAS, on March 12, 2012, U.S. EPA issued a memorandum that provided further guidance on developing SIPs specificto the 24-hour 35 ug/m3 PM2.5 NAAQS and set an initial attainment date of December 14, 2014, with a provision foran attainment date extension for up to five years; WHEREAS, the Rule requiresthat PM2.5 SIPs include air quality and emissions data, a control strategy, a modeled attainmentdemonstration, rate ofprogress (RFP) milestones, transportation conformity emission budgets, reasonably available control measure/ reasonably available technology (RACM/RACT) demonstration, and contingency measures; WHEREAS, the District prepared the San Joaquin Valley 2012 PM2.5 Plan (2012 PM2.5 Plan) to fulfill the planning requirements oftheAct and Rule forthe 24-hour 35 ug/m3 PM2.5 NAAQS; WHEREAS, ARB staff performed PM2.5 air quality modeling plus supplemental analyses of PM2.5 air quality monitoring data and trends, PM2.5 speciation data, and emission inventorytrends, consistentwith U.S. EPA modeling guidance;Resolution 13-2 

### 3
WHEREAS, the 2012 PM2.5 Plan air quality modeling is based on the latestscientific information developed from over 15 years ofcomprehensive air quality studies in the San Joaquin Valley; WHEREAS, the Rule requires that PM2.5 plans identify and evaluate sources ofdirectly emitted PM2.5 and the PM2.5 attainment plan precursors nitrogen oxides (NOx) and sulfur oxides (SOx); WHEREAS, the Rule requires thatto identify ammonia orvolatile organic compounds (VOCs) as attainment plan precursors in a PM2.5 plan, the state must provide a technical demonstration showing thatthe precursor significantly contributes to PM2.5 concentrations; WHEREAS, ARB staff performed modeling and technical analyses to determine whetherVOCs orammonia should be considered a significant precursorfor purposes of attaining the 24-hour PM2.5 standard; WHEREAS, the modeling and technical analyses quantified the magnitude ofthe PM2.5 concentration change and the effectiveness on a perton basis of reductions in each precursor; WHEREAS, the modeling and technical analyses showed that reductions in VOCs resulted in a very small increase in PM2.5 concentrations, therefore VOCs are not a PM2.5 attainment plan precursor; WHEREAS, the modeling and technical analysesfound that reductions in ammonia produced a much smaller decrease in PM2.5 concentrations than reductions in directly emitted PM2.5 and NOx. These analysesfurtherfound that reductions in directly emitted PM2.5 are fortytimes more effective, and reductions in NOx are ten times more effectivethan reductions in ammonia on a perton basis, therefore ammonia is not a PM2.5 plan precursor; WHEREAS, the attainment analysis forthe 2012 PM2.5 Plan demonstrates that a 30 percent reduction in NOx emissions from the projected 2007 emission levels, beyond the new reductions resulting from adopted regulations would be needed to attain the 24-hour PM2.5 NAAQS bythe December 14, 2014, deadline; WHEREAS, the Districtwas unable to identify additional new reductions sufficientforthe San Joaquin Valleyto attain the PM2.5 NAAQS by December 14, 2014; WHEREAS, in accordancewith section 172(b)(2) oftheAct, the 2012 PM2.5 Plan identifiesDecember 14, 2019, as the mostexpeditious attainment date; WHEREAS, the attainment analysis demonstrates thatthe 24-hour PM2.5 NAAQS will be metthroughoutthe San Joaquin Valley by the 2019 proposed attainment date;Resolution 13-2 

### 4 WHEREAS, ARB's adopted mobile source regulations reduce NOxemissions by 235 tons perday in the San Joaquin Valley between 2007 and 2019; WHEREAS, the PM2.5 attainment demonstration relies on adopted regulations and new District commitmentsto adoptfive control measures, including twothat reduce the impacts ofdirect PM2.5 targeting residential wood burning and commercial charbroiling; WHEREAS, the District plan also identifies seven further study measures including evaluating ammonia atconfined animal facilities; WHEREAS, consistentwith section 172(c) ofthe Act, the 2012 PM2.5 Plan demonstratesthe implementation of reasonably available control technologies (RACT) and reasonably available control measures (RACM) for direct PM2.5 and the area's relevant precursors; WHERAS, consistentwith section 172(c)(2) ofthe Act, the 2012 PM2.5 Plan demonstrates reasonable further progress (RFP) requirementtargets for attainment demonstrations; WHEREAS, consistentwith section 172(c)(9) ofthe Act, the 2012 PM2.5 Plan includes contingency measuresthat provide extra emissions reductions that go into effect withoutfurther regulatory action ifthe area fails tomake RFP orattainmentoh time; WHEREAS, consistentwith section 172(c)(3) ofthe Act, the 2012 PM2.5 Plan includes a comprehensive, accurate, current inventoryof

**emi~sions** data for directlyemitted PM2.5 and its precursors: oxides ofnitrogen (NOx), reactive organic gases (ROG), sulfur oxides (SOx), and ammonia (NH3) all sources ofthe relevant pollutants in the area; WHEREAS, consistentwith section 176 ofthe Act, the District developed transportation conformity emission budgets in consultation with the District, transportation agencies, and U.S. EPAthat conform tothe RFP and attainment emission levels; WHEREAS, federal law setforth in section 110(1) oftheActand Title 40, Code of Federal Regulations (CFR), section 51.102, requires that one or more public hearings, preceded by at least 30 days ofnotice and opportunityfor public review, must be conducted before adopting and submitting any SIP revisionto U.S. EPA; WHEREAS, as required by federal law, the District made the 2012 PM2.5 Plan available for public review at least 30 days before the District heejring; WHEREAS, following a public hearing on December20, 2012, the Governing Board of the Districtvoted to approvethe 2012 PM2.5 Plan, and to request a 5-year extension of the PM2.5 attainment dateto December 14, 2019;Resolution 13-2 

### 5 WHEREAS, the California Environmental Quality Act (CEQA) requires that no project which may have significant adverse environmental impacts be adopted as originally proposed iffeasible alternatives or mitigation measures are availableto reduce or eliminate such impacts; WHEREAS, to meetthe requirements ofCEQA, the District prepared an Initial Study and a Draft Negative Declarationforthe 2012 PM2.5 Plan, which was circulated for public review and comment from November 9, 2012, to December 8, 2012, and was adopted atthe public hearing on December20, 2012; WHEREAS, on December26, 2012, the Districttransmitted the 2012PM2.5 Plan to ARB as a SIP revision, along with proofof public notice publication and environmental documents in accordance with State and federal law. WHEREAS, the Board finds that: 1. The 2012 PM2.5 Plan meets all applicable Clean AirAct planning requirements, and includesthe required air quality and emissions data, modeled attainment demonstration, RFP demonstration, transportation conformity emission budgets, RACM/RACT demonstration, and the required contingency measures; 2. Adopted regulations, combined with new District control measures identified in the adopted 2012 PM2.5 Plan, will provide the emission reductions needed for meeting the PM2.5 NAAQS by the December 14, 2019 attainmentdate;
3. Adopted State mobile source control regulationswill provide the majority ofthe required contingency reductions, supplemented with additional District measures. These regulations will achieve additional emission reductions beyond those relied on in the RFP and attainmentdemonstrations;

. 4. Direct PM2.5 and NOx emissions in the San Joaquin Valley are projected to declinethrough 2019 and continue declining thereafter dueto adopted State, federal, and local controls; 5. The level of reductions needed to attain the PM2.5 24-hour NAAQS in the San Joaquin Valley makes it necessaryto request an attainment deadline of December 14, 2019, as allowed by the Act; and 6. ARB has reviewed and considered the Initial Study and Negative Declaration prepared forthe 2012 PM2.5 Plan and finds it complies with the requirements of CEQA. NOW, THEREFORE, BE IT RESOLVED thatthe Board hereby adopts the 2012 PM2.5 Plan as a revision to the California SIP.Resolution 13-2
