APPENDIX A: Weight of Evidence AnalysisAPPENDIX B: Documentation on Additional Emission Reductions Achieved Towards Meeting Aggregate CommitmentsEXECUTIVE SUMMARY

This report provides ARB staff’s assessment of the San Joaquin Valley Air Pollution Control District’s (District) 2015 PM2.5 State Implementation Plan ( 2015 PM2.5 SIP) revision. The SIP revision was developed to address increased PM2.5 concentrations that occurred due to weather conditions associated with California’s historic drought. These drought conditions have increased the challenge of meeting federal PM2.5 standards in the Valley, a region that already experiences the highest PM2.5 concentrations i n the nation. While the Valley had attained the 24

- hour standard and been nearing attainment of the annual standard 1 set in 1997 , the impacts of the drought have increased PM2.5 levels to an extent that the Valley can no longer attain by the 2015 statutor y deadline.

In 2008, t he San Joaquin Valley adopted a SIP to meet the 1997 PM2.5 standards. The U.S Environmental Protection Agency (U.S. EPA ) approved the SIP in 2011. The SIP control strategy focused on reducing directly emitted PM2.5, oxides of nit rogen (NOx), and oxides of sulfur (SOx). Through ongoing implementation of this control strategy, PM2.5 air quality in the Valley had been improving, with annual PM2.5 levels decreasing over 30 percent between 2001 and 2012. The Valley had met the 24

- hou r standard of 65 μg/m 3 in 2010, and by 2012 only a few sites remained above the annual standard of 15 μg/m 3 . However, the stagnant weather conditions and persistent lack of rainfall associated with the drought substantially increased PM2.5 levels in 2013, impacting both 24

- hour and annual average concentrations. These conditions pushed most sites in the centr al and southern Valley back over the annual standard, and increased 24

- hour concentrations in several locations to at or near the 65 μg/m 3 standard.

Because the Valley can no longer feasibly attain the standards by 2015, the District has prepared an upd ated plan to demonstrate attainment by the most expeditio us timeframe possible. This plan is designed to account for the potential that these adverse meteorological conditions may occur again in the future. The new attainment demonstration us es the appro ved modeling contained in the 2008 PM2.5 SIP, coupled with air quality data reflecting the impacts of the drought in 2013, and emission reductions expected through 2020 , which will put the Valley on a path to meet these standards over the next five years

.

The attainment demonstration includes the benefits of ARB and District control programs that provide significant ongoing emission reductions. Continued implementation of these control programs provides new emission reductions each year, resulting in a 38 percent decrease in NO x emissions and an eight percent decrease in PM2.5 emissions between 2012 and 2020. NO x reductions result from ongoing implementation of both new vehicle standards for passenger and heavy

- duty diesel vehicles and equipment, rules accelerating the turnover of legacy diesel fleets, and District rules addressing stationary source NO x emissions. PM2.5 emission reductions

1 To protect against the adverse health impacts of exposu re to PM2.5, U.S. EPA first set PM2.5 air quality standards in 1997, adopting an annual standard of 15 μg/m 3 , and a 24

- hour PM2.5 standard of 65 μg/m 3

1are the result of ongoing implementation of diesel on

- and off

- road equipment measures as well as the District’s re cently strengthened rule for wood

- burning fireplaces and heaters. These measures, along with additional reductions from enhancements to the District’s commercial charbroiling rule slated for adoption in 2016 provide the necessary control strategy. As a r esult, the modeling demonstrates the Valley will be below the 24

- hour standard by 2018, and attain the annual standard at all sites by 2020.

The 2015 PM2.5 SIP addresses the planning requirements specified under Subpart 4 of the Clean Air Act (Act) that allows for an attainment date extension to 2020. Under these provisions, the 2015 SIP includes a demonstration that most stringent measures are in place and that all commitments included in the 2008 SIP have been fulfilled

. Additional Act requiremen ts addressed in the 2015 SIP include reasonable further progress with corresponding milestones, transportation conformity and contingency

measures

.

In addition, because of the request for an attainment date extension , the SIP revision identifies a number of efforts to achieve further near

- term emission reductions beyond those from the existing control programs . These efforts include a District commitment to provide targeted incentive funding for the purchase of cleaner heavy

- duty trucks and woods tove repl acements, and ARB actions for heavy

- duty trucks that focus on cleaner combustion technologies, as well as introduction of zero and near

- zero emission equipment. The District has also committed to evaluate the potential for further emission reductions from rules that address agricultural conservation management practices, flares, and hot mix asphalt.

Finally, u nder the Act, U.S. EPA is also required to periodically review air quality standards and the latest health science. Based on this assessment, U.S. EPA has further st rengthened the PM2.5 standards , lowering the 24

- h our standard to 35 μg/m 3 in 2006 , and the annual standard to 12 μg/m 3 in 2012. New SIPs for these stan dards will be developed in 2016. The 2015 PM2.5 SIP revision lays out a course to provide for expeditious attainment of the 1997 standards by 2018 and 2020, and serves as a foundation for development of the 2016 SIP. The 2016 SIP will include a comprehensive assessment of the emission reduc tions and timeframe needed for attainment, and will identify further control measures. As part of this effort, ARB and District staff will also continue to closely monitor the ongoing drought, and its potential impacts on meeting the PM2.5 standards in th e Valley.

2I. OVERVIEW

Exposure to fine particulate matter (PM2.5) is associated with increased risk of hospitalization for lung and heart

- related illnesses and premature mortality, especially in children, the elderly, and people with existing health problems. The Clean Air Act (Act) requires the U.S. Environmental Protection Agency (U.S. EPA) to establish national ambient air quality standards to protect public health and regularly update them to reflect new health information. U.S. EPA first established a PM2.5 standard in 1997, a 24

- hour PM2.5 standard of 65 micrograms per cubic meter ( μ g/m 3 ) and an annual standard of 15 μ g/m 3

. Based on an extensive assessment and s cientific review of the health impacts of PM2.5 pollution, the 24

- hour PM2.5 standard was strengthened to 35 μ g/m 3 in 2006 and the annual standard was strengthened to 12 μ g/m 3 in 2012

. Meeting these standards provides critical public health protection, es pecially in the San Joaquin Valley which experiences the highest PM2.5 levels in the nation.

In Apr il 2008, the District adopted a State Implementation Plan (2008 PM2.5 SIP) that set out a strategy to attain the 1997 standards by April 2015 . This SIP w as approved by U.S. EPA in 2011

. A SIP to meet the revised 24

- hour standard of 35 μg/m 3 was adopted in late 2012 , and the SIP for the revised annual standard of 12 μg/m 3 will be developed in 2016. Each SIP serves as a building block to ensure incremental progress toward successively more stringent standards over time.

Through ongoing implementation of the control strategy in the 2008 PM2.5 SIP , the Valley had met the 24

- hour PM2.5 standard, and was nearing attainment of the annual standard. However, d ue to adverse weather conditions associated with California’s severe drought, PM2.5 levels increased substantially in 2013, affecting both 24

- hour and annual average concentrations. As a result, the San Joaquin Valley will not meet the 2015 attainment dea dline approved by U.S. EPA. The District has therefore adopted a SIP revision that de monstrates that the emission reductions that will occur over the next five years will place the Valley on a path towards expeditious attainment of the 1997 standards by 2020. The following sections provide an overview of the nature of the PM2.5 challenge in the San Joaquin Valley, the impacts of the drought, and the planning requirements associated with development of a new SIP to address these challenges.

A. Nature of PM2.5 Air Quality in the Valley

PM2.5 is a complex mixture of many different species generated from a wide array of emission sources. PM2.5 may be emitted directly into the air in the form of soot, smoke, or dust, or can be formed in the atmosphere as se condary particles from the reactions of precursor ga ses, including NOx, S Ox , volatile organic compounds (VOC ), and ammonia

. The relative mixture of these constituents in a region drives the nature of the needed control strategy.

The S an Joaquin Valley, e ncompassing 2 5 ,000 square miles in the central portion of California , is characterized by unique topography and meteorology

. Together with the

3Valley’s topography, the inversion

- prone meteorology of the region restricts airflow and favors the accumulation of pollutants. Valley weather patterns are typically characterized by dry summer s with moist w inter months

, which often include periods of heavy fog

. PM2.5 concentrations in the Valley exhibit a strong seasonal pattern, with the highest concentrations between November and February during ext ended periods of stagnant weather. These conditions are conducive to the buildup of PM2.5 over multiple days , as well as the formation of secondary ammonium nitrate

. Episodic activities such as seasonal wood burnin g also add to the pollution burden during the winter. These elevated wintertime concentrations in turn drive annual average levels. PM2.5 concentrations are higher in the central and southern portions of the Valley, with highest values recorded in the urb an areas of Fresno and Bakersfield.

The results of extensive research studies and comprehensive air quality modeling have been used to understand the types of sources contributing to PM2.5 and quantify the relative effectiveness o f reducing each PM2.5 pr ecursor. Organic and elemental carbon and ammonium nitrate are the largest contributors to both 24

- hour and annual average concentrations in the Valley

, accounting for approximately 70 to 90 percent of the total

mass . The major sources of organic and ele mental carbon in the Valley are mobile sources, residential wood burning, and commercial cooking. Modeling efforts have demonstrated directly emitted PM2.5 emission reductions provide significant benefit in reducing ambient PM2.5 concentrations , with orga nic and elemental carbon concentrations de creasing between 15 and 30 percent between 2004 and 2012.

Ammonium nitrate is formed in the atmosphere from chemical reactions of NOx, VOCs, and ammonia. It is th erefore important to understand which precursor controls are most effecti ve in reducing ammonium nitrate concentrations. Evaluation of both emissions inventory and monitoring data suggest that in the Valley’s ammonia

- rich conditions, NOx, rather than ammonia controls are more effective in reducing PM2.5 concentrations. This strong linkage between NOx emission reductions and decreases in ammonium nitrate concentrations is illustrated in Figure 1 for the Bakersfield and F resno monitoring site s

. Between 2004 and 2012, Valleywi de NOx emissi ons were reduced approximately 40 percent, with a commensurate reduction in ammonium nitrate concentrations

.

4Figure 1

. NOx Emissions vs Ammonium Nitrate Trends at Bakersfield and Fresno

In addition, air quality modeling has shown that while large reduct ions in NOx lead to similar reductions in ammonium nitrate, comparable reductions in ammonia are much less effective. During the winter months, reductions in NOx are approximately an order

o f magnitude more effective than reductions in ammonia o n a per ton basis , with an even greater differential on an annual average basis. Finally, air quality modeling has indicated that VOC emission reductions produce no PM2.5 benefit

. Based on this understanding of the nature of PM2.5 in the Valley, the SIP control strategy has focused on reducing directly emitted PM2.5, NOx, and SOx emissions. Through ongoing implementation of this multi

- pollutant control approach

, the Valley was making substantial progress towards attainment of the 1997 standards. Between 2001 and 2012, 24

- hour concentrations had decreased almost 40 percent , and annual concentrations had decreased over 30 percent . As a result, the Valley had attained the 24

- hour standard of 65 μg/m 3 in 2010, and by 2012, only a few sites remained over the annual standard of 1 5 μg/m 3

. Further discussion of the nature of PM2.5 air quality in the Valley , precursor effectiveness, and air quality progress is provided in Appendix A.

B. Impact of Drought on PM2.5 Attainmen t

Beginning in 2013, persistentl y high atmospheric pressure over the northeastern Pacific Ocean prevented winter storms from reaching the west coast, resulting in severe drought conditions in California. The stagnant weather conditions and lack of rainfall during the winter of 2013/14 d rove an increase in PM2.5 levels in all three regions of the Valley

. Due to nearly two months without rainfall, a majority of days during December 2013 and January 2014 recorded PM 2.5 concentrations greater than the 35 μg/m 3 24

-

5hour standard, a nearly threefold increase over the prior winter. These elevated wintertime concentrations affected both 24

- hour and annual average design values, especially in the central and southern Valley.

Figure 2 illustrates the trend in annual P M2.5 design values at three sites representing the northern, central, and southern portions of the Valley. Design values are used for SIP planning purposes, and are calculated as a three

- year average. While annual PM2.5 concentrations have been decreasin g over time

, Figure 2 highlights the considerable year

- to

- year variability that occurs in the Valley

. C atastrophic wildfires that occurred throughout northern California in 2008 for example affected design values for 2008

- 2010.

Figure 2 . Valley PM2.5 An nual Design Value Trends

Due to the weather conditions associated with the drought, from 2012 to 2013

, design values increased up to 15 percent at Valley locations

. While sites in the northern Valley remained below the standard, most sites in the centr al and southern Valley were pushed back over the annual standard, and 24

- hour design values at several locations increased to at or near the 65 μg/m 3 standard. The impact of large

- scale events such as wildfires and the drought underscore the challenge of meeting PM2.5 standards in the Valley. 0 5 10 15 20 25 30**PM2.5 Design Value (μg/m3)**

6C. New Planning Process Requirements

In light of a recent court decision, U.S. EPA has begun implementing PM2.5 standa rds under the particulate matter specific provisions of Subpart 4 of the Act. Subpart 4 establishes a step wise process for PM2.5 planning. All PM2.5 nonattainment areas are initially classified as moderate

. N onattainment area s that cannot demonstrate

a ttainment by the moderate area attainment deadline can request a reclassification to serious

. Finally , if needed, a serious area can request a five year extension if they have met all of their moderate and serious SIP obligations

, along with a demonstratio n the SIP includes the most stringent measures available or in practice in any other state

.

In light of the new classification requirements under Subpart 4, as a first step U.S. EPA classified all areas as moderate on June 2, 2014. However, a s a result of the increase in PM2.5 concentrations in 2013 , the San Joaquin Valley will be unable to attain the 1997 PM2.5 standard s by the initial moderate area attainment deadline of April 5, 20 15. On September 25, 2014, the District request ed a serious area classification with a December 31, 2015 attainment date

. On March 27, 2015, U.S. EPA formally classified the Valley as a serious nonattainment area and provided the option to request a further attainment date extension of up to five years

.

T he District has developed the 2015 PM2.5 SIP for the 1997 s tandard s to address the serious area SIP requirements along with a request for the further attainment date extension . The 2015 PM2.5 SIP address es the following SIP requirements associated wit h serious area requirements and the further attainment date extension :

• Demonstrate the impracticability of the Valley attaining by the ser i ous area deadline of December 31, 2015 ;

• Request a serious area attainment deadline extension to December 31, 2020;

• Attain the PM2.5 standards as expeditiously as practicable;

• Include Best Available Control Measures/Best Available Control Technology (B ACM/BACT) for serious areas;

• Include Most Stringent Measures (MSM) associated with an attainment deadline extension request ;

II. ATTAINMENT DEMONSTRATION

ARB and District staff have prepared an updated attainment demonstration that provides for expeditious attainment of the standards and which i s designed to account for adverse meteorological conditions associated with the drought should they occur again in the future. The new attainment demonstration uses the fundamental chemistry and ass ociated response of different PM2.5 constituents to emission controls reflected in the approved modeling in the 2008 PM2.5 SIP . This modeling science is coupled

7with 2013 design values and PM2.5 chemical composition reflecting drought impacts

, along with emission reductions expected through 2018 ( attainment for the 24

- hour standard) and 2020 ( attainment for the annual s tandard).

The attainment demonstration includes the benefits of ARB and District control programs that provide ongoing emission reductions. Continued implementation of these control programs provides new emission reductions each year, resulting in a for e casted 38 percent decrease in NOx emissions and an eight percent decrease in PM2.5 emissions between 2012 and 2020. These measures, along with additional reductions from enhancements to the District’s commercial charbroiling rule slated for adoption in 2 016 provide the necessary control strategy. As a result, the modeling demonstrates the Valley will be well below the 24

- hour standard by 2018, and attain the annual standard at all sites by 2020.

A. Modeling Methodology

The attainment demonstration approach for the current SIP is based on modeling conducted for the 2008 PM2.5 SIP , which addressed both the annual and 24

- hour PM2.5 standards. The atmospheric dynamics and associated response to emission reductions represent ed in this modeling, coupled with 2013 desi gn values and chemical composition, was used to project future (2020 for the annual standard and 2018 for the 24

- hour standard) design values. Photochemical modeling for the 2008 PM2.5 SIP was conducted following the U.S. EPA guidance (2007 U.S. EPA) 2 and was approved by U.S. EPA in 2011 (76 FR 69896, 76 FR 41338).

To assess the representativeness of the 2008 PM2.5 SIP modeling in relationship to the 2013/2014 meteorological conditions, ARB staff evaluated both the meteorological characteristics, as well as the chemi cal composition used in the modeling effort . The types of meteorological conditions conducive to PM2.5 formation in 2013/14 were similar to the 2000/01 meteorological conditions simulated in the 200 8 PM2.5 SIP . In addi tion , the PM2.5 chemical composition used in the 2008 PM2.5 SIP modeling was very similar to 2013, indicating common atmospheric chemistry regimes. Therefore, the 2008 PM2.5 SIP modeling response to emission reductions, applied to 201 3 design values reflecting the enhanced frequency of PM2.5 conducive conditions that occurred in 2013 , provides a suitable basis for the updated attainment demonstration. Additional information on the modeling methodology is provided in Appendix F of the 2015 PM2.5 SIP.

9C. Results

Results of the attainment demonstration modeling are provided in Table s 3 and 4. All sites in the SJV recorded 2013 design values at or below the 24

- hour standard of 65 μ g/m 3

. Eight of the fifteen sites in the SJV recorded 2013 design values over the annual PM2.5 standard of 15 μg/m 3 . The higher design values occurred in the Valley’s southern region (including the Bakersfield and Visalia) and the central region (around the Fresno urban area and Madera). Only one s ite in the northern region (Turlock) measured a 2013 annual design value over the standard.

The attainment demonstration modeling indicates that 2018 24

- hour design values will range between 24 μ g/m 3 and 5 2 μ g/m 3 , well below the 65 μg/m 3 standard. Further, by 2020 all sites in the Valley are projected to attain the annual standard. For those sites that exceeded the standard in 2013 , the projected 2020 annual design values range from 12.5 μ g/m 3 to 15.0 μ g/m 3

D. Weight of Evidence Analysis

U.S. EPA’s modeling guidance requires that the modeled attainment demonstration be accompanied by a weight of evidence analysis to provide a set of complementary analyses. Examining an air quality problem in a variety of ways p rovides a more informed basis for the attainment strategy as well as a better understanding of the overall problem and the level and mix of emissions control s needed for attainment. Appendix A provides the weight of evidence analysis prepared by ARB staff.

Following U.S. EPA guidance, this includes assessment of trends in air quality and emissions, source

- receptor models and other diagnostic analyses, addit ional modeling evaluations, and description of a conceptual model of PM2.5 in the Valley. The weight of evidence analysis draws upon the wealth of data collected in the Valley over the years, both from the routine monitoring network, as well as special stu dies. This assessment demonstrated the ongoing effectiveness of reduction s in NOx and directly emitted PM2.5 in reducing PM2.5 in the Valley. The substantial continuing reductions that will result from implementation of the ongoing control program are co nsistent with past progress, and the results predicted in the modeled attainment demonstration.

E. Consideration of 2014 Air Quality

The drought

- related meteorological conditions that affected PM2.5 concentrations in the San Joaquin Valley during 2013 continued into 2014. Although complete data for 2014 is not yet available, this section provides a preliminary assessment of 2014 air qu ality data in relation to the attainment demonstration.

11Despite the ongoing persistence of the drought, air quality conditions in 2014 generally improved at most locations, particularly in the northern and central portions of the Valley. This is an ind ication that although drought conditions are continuing, progress is resuming as a result of ongoing emission reductions. However, because 2014 design values will reflect the impact of multiple years of drought, a comparison to the 2013 design values used in the attainment demonstration is expected to be mixed, with some locations recording design values that are slightly lower, and other locations recording design values that are slightly higher. Based on an assessment of the PM2.5 levels predicted for 2 020 as well as ongoing trends and analyses, consideration of 2014 design values is expected to remain consistent with the current attainment demonstration. However, ARB and the District will continue to monitor the impacts of the drought and its relations hip to future PM2.5 attainment needs.

III. CONTROL STRATEGY

Attainment of the PM2.5 standard in the Valley will require the combined efforts of ARB

, federal, and District control programs. The following sections highlight ARB’s ongoing control programs and District control measures that provide the emission reductions included in the attainment demonstration.

A. State M obi le S ource Control Program

California has a long history of developing and implementing regulations to reduce emissions from on

- road and off

- road sources, which has resulted in the strongest mobile source control program in the nation. Several key recent regulatory efforts include the Advanced Clean Cars (ACC) program, the C leaner In

- Use Heavy

- Duty Truck Regulation, and the Off

- Road Regulation. Together, these programs are providing significant reductions in NOx and diesel particulate matter through 2020 and beyond.

The ACC p rogram, approved in Ja nuary 2012, is a suite of regulations that address es both ambient air quality needs and climate change goals. The ACC program combi nes the control of smog and PM2.5 causing pollutants, and greenhouse gas emissions , into

a package of requirements for passenger car model years 2015 through 2025. In 2025, cars under the ACC program will emit 75 percent less smog

- forming pollution than the average new car sold in 2012.

The Truck and Bus Regulation addresses the need to reduce emissions from older, high

- emitting, heavy

- duty trucks with long service lives

. The regulation represents a multi

- year effort to turn over the legacy fleet of engines and replace them with the cleanest technology available. Starting in 2012, the Truck and Bus Regulation phases in requirements so that by 2014 , nearly all vehicles operating in California will have PM emission controls, and by 2023 nearly all vehicles will meet 2010 model year engine emissions levels.

12The Off

- Road Regulation is designed to accelerate the penetration of the cleanest equipment into California’s fleets and significantly reduce emissions of diesel particulate matter and NOx from the over 150,000 in

- use off

- road diesel vehicles that operate in California by requiring their owners to modernize their fleets and install exhaust retrof its. The regulation affects dozens of vehicle types used in thousands of fleets by requiring owners to modernize their fleets by replacing older engines or vehicles with newer, cleaner models, retiring older vehicles or using them less often, or by app lyi ng retrofit exhaust controls.

B. District C ontrol Program

Comprehensive stationary and area source controls adopted by the District provide additional emission reductions that are an important element of the attainment strategy

. Recent District rules are highlighted in Table 5

. Compliance dates for these measures are intended to provide early emission reductions.

In 2014, the District strengthened the residential wood burning curtailment program under Rule 4901. Per rule requirements , the District prohibits use of wood

- burning heaters and wood burning fireplaces when PM2.5 air quality is forec ast to be above 20 μg/m 3 . The District Burn Cleaner incentive program combined with the tier ed compliance threshold in the r ule allows additional burn da ys fo r District registered U.S. EPA certified devices (up to forecasted PM2.5 level of 65 μg/m 3 ) to encourage the change

- out of high

- polluting devices and open

- hearth fireplaces to cleaner devices.

Other District rules reduce NOx emissions from residential c entral furnaces; boilers, steam generators and process heaters; glass melting furnaces; internal combustion engines; stationary gas turbines; residential water heaters; school bus fleets; and employer

- based trip reduction. The glass melting furnaces rule also reduces SOx and PM2.5.

Finally, in 2016 the District is scheduled to expand the scope of Rule 4692 for commercial charbroiling to include under

- fired charbroilers, with an expected 2017 compliance date. Research and demonstration projects evaluating the applicability of control technologies are cur rently underway

.

C. Incentive Programs

In addition to these regulatory efforts, ARB and the District implement incentive programs that invest significant amounts of funding to accelerate the purchase of clea ner technologies beyond those achieve d by regulations alone. Combined, California’s incentive programs have provided hundreds of millions of dollars dedicated to reduc ing emissions from both on

- and off

- road vehicles and equipment. Two of the largest pro grams are the Proposition 1B (Prop 1B): Goods Movement Emission Reduction Program, and the Carl Moyer Memorial Air Quality Standards Attainment Program (Moyer). Eligible projects span the mobile source sector, and include cleaner

on

- road and off

- road vehicles and equipment, marine, loc omotive, lawn and garden, light

- duty passenger vehicles, and agricultural equipment. The District also derives

13additional funding for incentive programs from Motor Vehicle Surcharge Fees, the District’s Indirect Source R ule, and Voluntary Emission Reduction Agreements. In the 2014/2015 fiscal year budget, the District authorized $156 million in incentive funding from local

, State, and federal funding sources.

D. Further Near

- Term Emission Reductions

As discussed in the Overview section , in response to the increasing body of evidence regarding the adverse impacts of exposure to PM2.5, U.S. EPA has further strengthened the PM2.5 standards, lowering the 24

- hour standard to 35 μg/m 3 in 2006

, and the annual standard to 12 μg/m 3 in 2012. New SIPs for these standards will be developed in 2016, as well as for the revised 8

- hour ozone standard of 75 parts per billion . These SIPs will include a comprehensive assessment of the reductions and timeframe necessary for attainment of the more health p rotective standards. However, in light of the request f or an attainment date extension , as well as the need to continue

14to accelerate progress towards attainment of all of the standards, the 2015 PM2.5 SIP identifies a number of efforts to achieve further near

- term emission reductions.

1. District Commitments for Further Emission Reductions

As part of the 2015 PM2.5 SIP , the District has committed to providing targeted incentive funding for two key categories

- heavy

- duty trucks and woodstoves. This includes a commitment to allocate $10 million between 2016 and 2020 for the replacement of heavy

- duty trucks in the Valley , achieving additional NOx and PM2.5 emission reduc tions. The District also commits to allocating $7.5 million for the replacement of old high polluting wood burning device s between 2016 and 2020 to achieve additional PM2.5 emission reducti ons

. In addition, the District has committed to evaluate the pote ntial for further emission reductions from rules that address conservation management practices, flares, and hot mix asphalt. The District commits to conduct the evaluations described below and to include any identified additional actions for reducing emi ssions and implementation schedules in the 2016 SIP for the revised annual PM2.5 standard.

a) Rule 4311

— Flares

The District commits to undertaking a comprehensive review of flare minimization plans submitted under Rule 4311. The District intends to conduc t the evaluation and have a draft report available for public review and comment by December 0 1, 2015. After addressing public comments, the District commits to fi nalize this report by March 31, 2016.

b) Warm Mix Asphalt

The District commits to a number of actions to evaluate and promote the use of warm mix asphalt in the Valley. The District intends to conduct the evaluation and have a draft report available for public review and comment by December 0 1, 2015. After addr essing public comments, the District commits to fi nalize this report by March 31, 2016. c) Rule 4550

— Conservation Management Practices

The District commits to conduct an evaluation of Rule 4550 and have a draft report available for public review and comment by May 31, 2016. After addressing public comments, the District commits to finalize this report by October 31, 2016.

2. ARB Actions for Emission Reductions from the Truck Sector

Ongoing NOx and diesel PM reductions from mobile sources are a key focus of the control strategy to bring the San Joaquin Valley into attainment of federal PM2.5 standards. Within the mobile source sector, heavy

- duty trucks represent the largest source of both NOx and diesel PM emissions in the Valley. Recognizing the critical

n eed to continue to clean up the heavy

- duty diesel fleet, ARB is taking a number of

15additional actions to further reduce emissions and provide ongoing benefits in the Valley. These efforts are outlined in the recently released sustainable freight report wh ich sets out ARB’s vision for a clean freight system, together with the immediate and

near

- term steps that ARB will take to support use of zero and near

- zero emission technology. T hese ARB actions related to the heavy

- duty truck sector provide additional emission reductions in the Valley and ensure progress towards attainment of the PM2.5 standards. Further description of the proposed actions is provided below.

California’s Truck and Bus R egulation targeting emission reductions from the nearly one milli on existing diesel trucks and buses that operate on California roads each year is one of the most important components of ARB’s program to reduce emissions from diesel vehicles. This comprehensive program is intended to significantly reduce emissions from existing diesel vehicles throughout the State through a mix of exhaust and vehicle retrofits and vehicle turnover to the cleanest technologies. Over the next five years imple mentation of the Truck and Bus R egulation will reduce NOx emissions by 34 percent , and diesel PM emissions by 78 percent , with 2020 emission reductions of 17.6 tpd of NOx and 1.7 tpd of PM2.5

. As part of ARB’s sustainable freight report, ARB has identified a number of immediate actions to continue to reduce emissions and health risk from heavy

- duty trucks. These include focused enforcement efforts related to compliance with the Truck and Bus Re gulation, as well as opportunities to leverage resources by utilizing agreements with local air districts. Other near

- term efforts proposed focus on cleaner combustion technologies, as well as introduction of zero and near

- zero emission equipment. These include development of strategies to ensure durability and in

- use performance. These efforts will focus on enhanced truck inspection and maintenance programs, new certification and warranty requirements, and provisions to ensure proper repairs are conduct ed. Strategies will also be developed to increase the flexibility for manufacturers to certify advanced truck engines and vehicle systems to provide for accelerated introduction of cleaner new technologies into the market.

Incentive programs also play a n important role in achieving additional emission reductions from the current on

- road fleet beyond current regulatory requirements, as well as transition ing from current technologies to zero and near

- zero technologies

. Because trucks used in the agricultu ral industry are an important sector in the Valley, ARB proposes to partner with the Valley Air District to focus investments for agricultural trucks to accelerate turn over to cleaner engines. ARB’s Air Quality Improvement Program (AQIP) and Low Carbon T ransportation Investments are additional incentive programs that are designed to support the development and commercialization of advanced technologies . Statewide, more than $ 220 million has been allocated for fiscal year s 201 4 /2015 and 2015/2016 projects . As part of these programs ARB will pursue opportunities to focus Valley funding on projects related to traditional Hybrid and Zero

Emission Truck and B us Voucher Incentive Project s , z ero

, and a dvanced t echnology f re ight d emonstration p rojects

.

16IV. CLEAN AIR ACT REQUIREMENTS

In addition to the elements related to the attainme nt demonstration, the Act also requires SIPs for serious PM2.5 nonattainment areas requesting an attainment date extension to address the following requirements :

• Demonstration that the State complied with all requirements and commitments pertaining to the area in the SIP;

• Provisions to assure that the best available control measures/best available control technology (BACM/BACT) for the con trol of PM2.5 and PM2.5 precursors be implemented no later than four years after area reclassification to serious;

• The SIP includes the most stringent measures (MSM) that are included in the implementation plan of any s tate or a re achieved in practice in any s tate, and can feasibly be implemented in the area;

• Base year emission inventories and future year forecasts for manmade sources of PM2.5 and PM2.5 precursors;

• Plan provisions that require reasonable further progress (RFP) and quantitative milestone s ;

• Provisions for sufficient c ontingency measures for RFP and attainment; and

• Transportation conformity emission budgets to ensure transportation plans and projects are consistent with the SIP.

A. Demonstration SIP Commitments have been Me t

The 2008 PM2. 5 SIP contained a n overarching enforceable commitment to reach the level of emissions specified in the attainment demonstration

. The attainment emission targets specified in this commitment are achieved through the following elements of the ARB and Distri ct control strategy:

• Ongoing emission reductions that occur each year as the result of implementation of already adopted measures ;

• A commitment to propose a specified list of new measures by specified deadlines ; and

• A commitment to achieve an aggregate tonnage of emission reductions from new ARB and District measures necessary to reach the attainment targets

. These three elements are not independent of each other, but rather are the combination of integrated actions required to meet the attainment emiss ion targets. Further, the aggregate reductions can be achieved by new measures as described in the SIP

, a lternative measures identified by ARB and the District , and i ncentive program emission

17reductions from the replacement or retrofit of aging, higher polluting pieces of equipment.

Subsequent to the adoption of the 2008 PM2.5 SIP, both ARB and the District engaged in comprehensive rulemaking efforts to implement the SIP commitments. These rulemaking efforts are developed through a public process that involve public notices

, public comment opportunities, and with proposed and final rules published on agency web sites. Once regulations are submitted to U.S. EPA, they act on the measure through notice

- and

- comment rulemakings.

By the time U.S. EPA appr oved the 2008 PM2.5 SIP in 2011, both ARB and the District had acted on the majority of measures included in the SIP , and U.S. EPA had approved many of these regulations and programs and credited the emission reductions toward

mee ting the aggregate commitm ent. Table 6 summarizes the ARB and District emission reduction commitments, as well as the reductions that U.S. EPA had already credited at the time of SIP approval. As can be seen in the table, the District had already exceeded the amount of NOx and SO x reductions needed, and ARB had achieved almost all of the needed PM2.5 reductions. U.S. EPA approval of these emission reductions is documented in the Federal Register notice and associated Technical Support Document (76 FR 41338; 76 FR 69896 ).

Table 6

ARB Commitment 17.1 2.3 0.0 EPA Credited 2.1 1. 8 0.0

Subsequent to approval of the SIP in 2011 , ARB and the District have continued to achieve further enforceable emission reduction s that are creditable towards meeting the aggregate commitment

. As a result, both ARB and the District have taken action on all of the control measures proposals contai ned in the 2008 PM2.5 SIP, and have achieved the aggregate emission reductions necessary to reach the attainment emission targets.

Table s 7 and 8 document the actions taken for each of the ARB and District measures along with the original expected actio n dates committed in the 2008 PM2.5 SIP . In addition to new ARB control measures, State action s also include measures from the Bureau of Automotive Repair (BAR) and the Department of Pesticide Regulation (DPR).

Commitment Met YES YES YES

The a dditional District emission reductions were achieved from measures that had not yet been approved at the time of U.S. EPA’s 2011 SIP approval, incentive

- based reduction programs, and enhanced implementation of the District’s residential wood burning rule. Further ARB emission reductions were achieved from incentive

- based reductions that were approved by the Board in October 2014, implementation of the ARB’s Portable Equipment Registration Program/Portable Engine ATCM, and assessment of actual fleet compliance with ARB’s Truck and Bus regulation. Further d o cumentation of the emission reductions from these programs is included in Appendix B

.
As a result of these measures, the District exc eeded their NOx commitment by 7.0 tpd

, the ir SOx commitment by 2 .7 tpd, and achieved all but 0.9 tp d of the required PM2.5 reductions (Table 9 ) . Similarly, ARB reductions e xceeded the NOx commitment by 6.9 tpd and achieve d all of the PM2.5 reductions (Table 10 )

. Because PM2.5 is comprised of many different constituents, multiple combinations of emission levels of different precursors can all provide for attainment. In addition, relationships have been established that compare the benefits of achieving reductions in different PM2.5 precursors. Modeling conducted as part of the 2008 PM2.5 SIP demonstrated that a reduction of 9 tpd of NOx emissions provides equivalent a ir quality improvement as a 1 tp d reduction in directly emitted PM2.5 emissions. This emission s benefit ratio was approved by U.S. EPA for demonstrating con tingency reductions in the 2008 PM2.5 SIP (79 FR 29327 )

. As shown in Table 11 , t he 13.9 tpd of surplus NOx reductions achieved through implementation of the ARB and District measures, together with the PM2.5 reductions achieved result in emission levels t hat in aggregate are sufficient for attainment based on the 2008 PM2.5 SIP modeling. The additional surplus SOx emission reductions provide further assurance that overall emission levels have been met.

22B. Best Available Control Measures and Most Stringent Measures

The particulate matter provisions in the Act specify a step

- wise process for the required level of emission control in a SIP, depending upon the severity of the air quality problem and amount of time a nonattainment area needs to meet the PM2.5 standard. For a serious nonattainment area, B est A vailable C ontrol M easures ( BACM ) are the required level of control. BACM is required for those sources with emissions that are a significant contributor to the nonattainment problem. U.S. EPA define s BACM to be the maximum degree of emission reduction s achievable from a source or source category determined on a case

- by

- case basis considering energy, economic, and environmental impacts. Serious areas that cannot achieve the standard by the serious area attainment da te are allowed to request a five

- year extension if they have BACM in place and the SIP demonstrates it includes most stringent measures (MSM). The Act specifies that MSM is the maximum degree of emission reduction that has been required or achieved from a source or source category in other SIPs or in practice in other states and can feasibly be implemented in the area.

The following sections summarize the BACM/MSM demonstrations conducted by ARB and the District. These analyses are further described in Chapter 5 and Appendix C and D of the 2015 PM2.5 SIP

.

1. ARB Assessment

ARB’s comprehensive mobile source control program relies on four fundamental approaches:

• stringent emissions standards that minimize emissions from new vehicles and equipment;

• in

- use programs that target the existing fleet and require the use of the cleanest vehicles and emissions control technologies;

• cleaner fuels that minimize emissions during combustion; and,

• incentive programs that remove older, dirtier vehicles and equipment and pay for early adoption of the cleanest available technologies.

This multi

- faceted approach has spurred the development of increasingly cleaner technologies and fuels and achieved significant emission reductions across all mobile source sectors that go far beyond national programs or programs in other states

. These efforts extend back to the first mobile source regulations adopted i n the 1960s, and pre

- date the Act of 1970, which established the basic national framework for controlling air pollution. In recognition of the pioneering nature of ARB’s efforts, the Ac t provides California unique authority to regulate mobile sources more stringently than the federal gov ernment by providing a waiver of preemption for its new vehicle emission standards under Section 209(b). This waiver provision preserve s a pivotal role for California in the control of emissions from new motor vehicles, recognizing that California serves as a

23laboratory for setting m otor vehicle emission standards

. Since then, the ARB has consistently sought and obtained waivers and authorizations for its new motor vehicle regulations. ARB’s history of progressively strengthening standards as technology advances, coupled with the waiver process requirements, ensures that California’s regulations remain the most stringent in the nation.

ARB ’s BACM/MSM assessment for the mobile source categories under ARB’s regulatory authority included:

• Documentation of California waivers and authorizations granted to California to enforce its own standards for new vehicles and engines;

• Description of the scope and stringency of California’s regulations and comparison to programs implemented at the federal level or in other states;

• Documentation of state s that have been granted waivers to adopt California rules; and,

• Discussion of incentive programs and other initiatives that go beyond regulatory requirements to provide an enhanced level of emission reductions.

This assessment demonstrates that ARB has continued to enhance and accelerate reductions from our mobile source control programs through the implementation of more stringent engine emissions standards, in

- use requirements, incentive funding, and other poli cies and initiatives. These efforts not only ensure that all source sectors continue to achieve maximum emission reductions through implementation of the cleanest current technologies, but also promote the ongoing development of more advanced zero and

near

- zero technologies. As a result, California’s mobile source control programs reflect the most stringent and feasible level of emissions control in the nation and fully meet the requirements for BACM and MSM.

2. District Assessment

Through multiple plann ing processes to meet federal ozone and PM2.5 standards, the District has adopted a comprehensive suite of control measures

. These rules address a wide range of sources, from residential wood burning and sources of fugitive dust, to industrial facilities and stationary engines. The District followed a multi

- step process outlined in U.S. EPA’s guidance to identify BACM and MSM for each of these sources and determine whether District programs met these requirements. Although ammonia is not considered a sig nificant PM2.5 plan precursor, the District also included an assessment of rules addressing c onfined a nimal f acilities

, o rganic m aterial c omposting

, and b iosolids, a nimal m anure, and p oultry l itter o perations . The District’s review of its rules followed the five steps below :

1. Developed a detailed i nventory (provided in the 2015 PM2.5 SIP Appendix B).

2. Based on the attainment demo nstration information in the Plan and the 2012 baseline inventory determined which sources are significant.

243. From a list of 40 source categories, the District identified six source categories that have emissions over the significance (de minimis) level for PM2.5, NOx or SOx. These include open burning, glass melting furnaces, conservation management practices, commercial charbro iling, wood burning fireplaces and woodburning heaters, and paved and unpaved roads.

4. Identified potential BACM and MSM from significant sources in other implementation plans or used in practice for each significant source category evaluating technologi cal and econ omic feasibility. Further, the District also conducted control measure evaluation s for the remaining de minimis source categories.

5. Compared potential BACM and MSM for each source category to the corresponding adopted District rule. District rules and source categories were compared to federal and state regulations and standards and other air district rules and standards.

Base d on the results of this analysis , the D istrict determined that District rules meet the requirements for BACM and MS M in consideration of the f easibility and cost effective ness criteria defined in the Act

. Nevertheless, as part of the 2015 PM2.5 SIP control strategy, the District has committed to strengthen the commercial charbroiling Rule 4692. The District has also committed to evaluate the potential for further emission reductions from rules addressing agricultural conservation management practices, flares, and hot mix asphalt.

C. Emissions Inventory

SIPs must contain base

- year inventories for PM2.5 and all precursor emissions as well as future year forecasts for all pollutants identified as PM2.5 attainment plan precursors. An emission inventory consists of a systematic listing of the sources of air pollutants with an estimate of the amount of pollutants from each s ource or source category over a given period of time.

ARB and District staff worked jointly to prepare an updated emission inventory (annual average and winter) for the 2015 PM2.5 SIP

. The inventory includes a category

- by

category review and update using the most recent information available on emissions

generating activities and anticipated population and economic growth in the region. Additional information on the emission inventory m ethodologies and resulting base and future year emissions can be found in Appendix B of the 2015 PM2.5 SIP

.

D. Reasonable Further Progress and Quantitative Milestones

The Act requires SIPs to provide steady air quality progress by reducing emissions during the years leading to attainment. This is known as Reasonable Further Progress (RFP). As part of this requirement, a SIP must include quantitative milestones to be achieved every three years until the area is redesignated to attainment and which

25demonstra tes RFP. The 2015 PM2.5 SIP identifies RFP emission levels for NOx, SOx, and PM2.5 for 2014 and 2017 that show generally linear progress in emission reductions towards attainment of the annual standard in 2020. These emission levels for 2017 along with t he 2020 attainment emis s ion levels s erve as the quantitative milestones required under the Act.

Targeting the most effective precursors is essential to ensuring air quality progress. Ammonium nitrate comprises a large fraction of PM2.5 concentrations and therefore reducing ammonium nitrate concentrations is a necessary element of the control strategy. As discussed earlier, while both NOx and ammonia participate in the formation of ammonium nitrate, NOx reductions are at least an order of magnitude mo re effective than ammonia reductions

, and therefore the 2015 PM2.5 SIP control strategy focuses on NOx reductions. As shown in Table 12 , NOx emission levels are projected to be well below the level required for linear progress in 2014 and 2017, including reductions required for contingency. Although ammonia is not considered a significant precursor and therefore RFP is not required , ammonia emissions are also provided in the table. While ammonia emissions are increasing slightly over the progress period, given the atmospheric response to NOx and ammonia emissions, the combined emission levels of NOx and ammonia that are projected to occur through the 2020 attainment year provide for the required generally linear air quality progress. The NOx Equivalent em ission levels are projected to be below the level required for linear progress in 2014 and 2017.

Additional documentation for NOx, PM2.5 and SOx RFP is provided in Chapter 6 of the 2015 PM2.5 SIP. For the future 2017 and 2020 quantitative milestones, ARB further commits to provide U.S. EPA with a letter reporting that the emission inventory milestones have been met and the status of any emission reduction commitments. The letter for the respective 2017 and 2020 m ilestones will be provided by March 31, 2018

a nd March 31, 2021, as specified in the Act.

E. Contingency Measures

Contingency measures provide additional emission reductions in the event a nonattainment area fails to achieve RFP targets or attain the PM2.5 standard by its attainment date. These contingency measures are to take effect without further ARB or District action and consist of reductions that are not required as part of demonstrating attainment

. Early reductions from the control strategy beyond those needed for RFP provide for 2017 contingency. In addition, reductions that accrue between 2020 and

262021 from implementation of new rule requirements provide the majority of the attainment contingency reduc tions. Additional reductions achieved through incentive programs complement the attainment contingency reductions. The break down of the 2020 attainment year contingency re ductions is provided in Table 13

. For the interim 24

- hour 2018 attainment deadline , additional reductions in 2019 provide for 0.2 tpd of PM2.5 and 10 tpd of NOx reductions. Further discussion of contingency measures is provided in Chapter 6 of the 2015 PM2.5 SIP

F. Transportation Conformity Budgets

Under section 176(c) of the Act, transportation activities that receive federal funding or approval must be fully consistent with the SIP. U.S. EPA’s transportation conformity rule 3 details requirements for establishing motor vehicle emission budgets (budgets) in SIPs for the purpose of ensuring the conformity of transportation plans and programs with the SIP.

The 2015 PM2.5 SIP establishes county

- level on

- road motor vehicle emission budgets for each RFP milestone year, as well as f or the attainment year. Emission budgets for direct PM2.5 and NOx were calculated us ing EMFAC2014 and reflect annual average emissions. The emission budgets established in the 2015 PM2.5 SIP fulfill th e requirements of the Act and U.S. EPA regulations to ensure that transportation projects will not interfere with progress and attainment of the annual PM2.5 standard. Additional detail on the on

- road motor vehicle emission budgets can be found in Chapter 6 of the 2015 PM2.5 SIP

.

27V. ENVIRONMENTAL IMPACT

A. In troduction

ARB has determined that the 2015 PM2.5 SIP is exempt from the requirements of CEQA. A brief explanation of this determination is provided in section B below. ARB’s regulatory program, which involves the adoption, approval, amendment, or repeal of standards, rules, regulations, or plans for the protection a nd enhancement of the State’s ambient air quality, has been certified by the California Secretary for Natural Resources under Public Resources Code section 21080.5 of the California Environmental Quality Act (CEQA) (14 CCR 15251(d)). Public agencies with certified regulatory programs are exempt from certain CEQA requirements, including but not limited to, preparing environmental impact reports, negative declarations, and initial studies. ARB, as a lead agency, prepares a substitute environmental document (referred to as an “Environmental Analysis” or “EA”) as part of the Staff Report prepared for a proposed action to comply with CEQA (17 CCR 60000

- 60008). If the Board approves the 2015 PM2.5 SIP, a Notice of Exemption will be filed with the Office of the Secretary for the Natural Resources Agency and the State Clearinghouse for public inspection.

B. Analysis

ARB has determined that the 2015 PM2.5 SIP is exempt from CEQA under the general rule or “common sense” exemption (14 CCR 15061(b)(3)). CEQA Guidelin es states “the activity is covered by the general rule that CEQA applies only to projects which have the potential for causing a significant effect on the environment. Where it can be seen with certainty that there is no possibility that the activity in q uestion may have a significant effect on the environment, the activity is not subject to CEQA”. The proposal is also categorically exempt from CEQA under the “Class 8” exemption (14 CCR 15308) because it is an action taken by a regulatory agency for the p rotection of the environment. The 2015 PM2.5 SIP efforts include a District commitment to provide targeted incentive funding for the purchase of cleaner heavy

- duty trucks and woodstove replacements, and proposed ARB actions for heavy

- duty trucks that focu s on cleaner combustion technologies, as well as introduction of zero and near

- zero emission equipment. In addition, the District has committed to evaluate the potential for further emission reductions from rules that address agricultural conservation man agement practices, flares, and hot mix asphalt. The intent of these efforts is to decrease the PM2.5 emissions within the San Joaquin Valley in order to meet the attainment goal set by the U.S. EPA. Based on ARB’s review it can be seen with certainty that there is no possibility that the 2015 PM2.5 SIP may result in a significant adverse impact on the environment. Further, the action is designed to protect the environment and ARB found no substantial evidence indicating the proposal could adversely affect air quality or any other environmental resource area, or that any of the exceptions to the exemption applies (14 CCR 15300.2). Therefore, this activity is exempt from CEQA.

28VI. SUMMARY AND RECOMMENDAT ION

Meeting federal PM2.5 standards in the Valley is a continuing challenge that has been further exacerbated by the weather conditions associated with the ongoing drought. The 2015 PM2.5 SIP lays out a course for expeditious attainment of the 1997 stand ards by 2018 and 2020, and serves as a foundation for development of the 2016 SIP to meet the more stringent 24

- hour and annual PM2.5 standards adopted in 2006 and 2012. ARB staff has determined that the 2015 PM2.5 SIP meets the requirement of the Act and therefore recommends that the Board approve the SJV 2015 PM2.5 SIP as a revision to the California SIP.

However, the need for continuing action is essential. In order to continue to pursue further near

- term emission reductions, the District has commit ted to provide targeted incentive funding for heavy

- duty trucks and wood stove replacements, as well as committed to evaluate the potential for additional emission reductions from a number of

sources currently regulated under District rules . ARB has also identified a number of actions related to achieving a cleaner heavy

- duty truck fleet as part of the sustainable freight strategy, along with continued incentive funding.

As the drought continues, ARB and District staff will continue to closely monitor P M2.5 air quality conditions and potential impacts on attainment of the standards. Finally, because atmospheric chemistry can change over time, and as new scientific information becomes available, ARB will also continue to evaluate the r ole of ammonia as part of the 2016 SIP.

- iiEXECUTIVE SUMMARY

As part of the at tainment demonstration, the SJV 2015 PM2.5 Plan s pecifically identifies the: 1) most expeditious date of when the Valley will attain the standard s, 2) relative efficacy of precursor emission reductions , 3) amount of emi ssions needed to attain, and 4) control strategy . The weight of evidence analysis provides a set of complementary analyses that supplement the required model based attainment demonstration

. Because all methods have strengths and weaknesses, examining an air quality problem in a variety of ways offsets the limitations and uncertainty that are inherent in air quality modeling. This approach also provides a better understanding of the overall problem and the level and mix of emissions controls needed for attainment.

A nalyses con ducted by ARB and District staff, along with findings from the California Regional Particulate Air Quality Study ( CRPAQS) provide the supplemental information supporting the attainment demonstration. CRPAQS was a public/private partnership designed to adv ance our understanding of the nature of PM2.5 in the Valley and guide development of effective control strategies. The study included monitoring at over 100 sites as well as data analysis and modeling, results of which have been published in over 60 paper s and presented at national and international conferences.

Studies such as CRPAQS provide valuable information that supports the SIP process in a number of ways. First, these studies provide additional observational data that help to provide a more de tailed understanding of the nature of the PM2.5 problem in the San Joaquin Valley. This data also is used to update the fundamental algorithms contained within air quality models, thereby enhancing their ability to simulate observed air quality conditions . Finally, they provide an improved basis for model applications used in the preparation of SIPs and a more robust platform for evaluating the response to emission controls and predicting future air quality

.
In 2006, U.S. EPA tightened the 24

- hour PM2.5 standard to 35 μ g/m 3 and in 2012, the annual standard to 12 μ g/m 3 . T he District adopted the 2012 PM2.5 Plan addressing the 35 μ g/m 3 24

- hour standard and U.S. EPA proposed approval of the Moderate area requirements in this Plan in 2015 . The SIP for the 12 μ g/m 3 annual standard will be due to U.S. EPA in 2016.

What are the key sources of the PM2.5 problem in the Valley ?

The geography of the San Joaquin Valley, along with weather patterns influence the accumulation, formation, and dispersion of PM2.5. As a result, PM2.5 concentrations are generally higher in the central and southern portions of the Valley, with highe st values in the urban areas of and around Fresno and Bakersfield . Concentrations are highest during the winter months of November through February. During the winter of 2013/2014, a persistent high

- pressure weather system over Northern California cause d the atmosphere to beco me stagnan t, which i n conjunction with nearly two months without rain, resulted in episodes of high PM2.5 concentrations lasting for several

A

- 1weeks. These elevated wintertime PM2.5 concentrations also resulted in highe r annual average concentrations.

A mmonium n itrate and carbon com pounds (organic and elemental carbo n) are the larges t chemical constituents, comprising , on an annual average basis, 70 to 80 percent of the PM2.5 mass and about 90 percent of winter peak day PM2.5 mass. Geological material (dust) and ammonium sulfate are small er contributors.

Source apportionment studies confirm the importance of ammonium nitrate contributions to PM2.5 and also identify motor vehicle exhaust and biomass burning as significant contributors. Sources of biomass burning include residential wood combustion, agricultural and prescribed burning , and cooking

. Ammonium nitrate is formed in the atmosphere from reactions of gaseous precursors. Emissions of nitrogen oxides (NOx) from mobile sources and stationary combustion sources react with ammonia which is primarily emitted from livestock operations and fertilizer application

. Heavy duty diesel vehicles account for approximately 50 percent of annual average NOx emissions, followed by farm and off

- road equipment, other vehicles, trains, and stationary combustion sources. The stagnant, cold, and damp conditions that occur during th e winter promote the formation and accumulation of ammonium nitrate. Elevated concentrations can be found at both urban and rural sites.

In contrast, organic carbon is highest in urban areas due to emission s from residential wood combustion, commercial cooking operations, and mobile source tailpipe emissions which are largest in urban areas. Due to the localized urban increment from these activities , which adds to the more regional ammonium nitrate concentr ations, the highest PM2.5 concentrations in the Valley usually occur at urban sites in the winter

.

What is the effectiveness of controlling different PM2.5 precurs ors ?

In addition to directly emitted PM2.5 there are multiple precursor pollutants that lead to PM2.5 formation (NOx, sulfur oxides (SOx), volatile organic compounds (VOCs) , and ammonia).

Given the large cont ribution of ammonium nitrate to high PM2.5 concentrations , a number of different studies and analyses were evaluated to understand the role of VOCs and ammonia in ammonium nitrate formation in the San Joaquin Valley. The amount of ammonium nitrate produced depends upon the relative atmospheric abundance of its precursors. It is therefore important to understand which precursor controls are most effective in reducing ammonium nitrate concentrations. In simple terms, the precursor in shortest supply will limit how much ammonium nitrate is produced. This is know n as the limiting precursor and controls of this precursor will have the most significant benefits in reducing PM2.5 concentrations.

The precursor assessment for the 2015 PM2.5 plan included evaluation of emissions inventories, monitoring studies, and p hotochemical modeling analyses of ammonium

A

- 2nitrate sensitivity to precursor emission reductions. While emissions inventory and monitoring data can indicate the relative abundance of the different precursors, photochemical models provide a quantitative app roach to simulate the effects that emission reductions in each of gaseous precursors would have on the predicted ammonium nitrate concentrations

.

Evaluation of emissions inventory data concluded that the ammonia

- rich conditions throughout the Valley demon strate that NOx rather than ammonia is the limiting precursor during wintertime PM2.5 episodes as well as on an annual average basis. D ata of monitoring conducted during wintertime PM2.5 episodes, further corroborate this finding. In addition, photochemic al modeling studies found that while large reductions in NOx led to commensurate reductions in ammonium nitrate, comparable reductions in ammonia were much less effective

. Precursor sensitivity modeling conducted for the 2012 PM2.5 Plan showed that on a p er ton basis, reductions in NOx are approximately nine t imes more effective than reductions in ammonia. Finally, evaluation of ambient air quality trends show that reductions in NOx emissions, gaseous NOx concentrations, and particulate nitrate all track each other well.

Evaluation of monitoring studies also provided some evidence that VOCs could be important at times, however

, these studies were not conclusive. Therefore photochemical modeling studies are more appropriate to assess the overall impact of VOC controls. These modeling studies found that at current NOx levels, further VOC emission reductions produce essentially no benefit, and in some instances may actually lead to an increase in ammonium nitrate concentrations. Findings from these prior studies were supported by precursor sensitivity modeling conducted for the 2012 PM2.5 SIP, which indicated a very small disbenefit from reductions in VOCs.

Based on the weight of evidence presented from historical studies, coupled with the modeled precursor sensitivity analyses conducted as part of the 2012 PM2.5 Plan, ammonia controls provide only a very small benefit in reducing PM2.5 levels, and VOC contro ls can result in a disbenefit. However, directly emitted PM2.5, NOx and SOx controls have been documented to result in PM2.5 air quality improvement and are therefore the focus of the control strategy in the San Joaquin Valley

. What p rogress has the pri or control approach achieved in reducing PM2.5 concentrations ?

T he implemented control strategy reducing directly emitted PM2.5, NOx, and SOx emissions has resulted in measurable PM2.5 air quality improvements. Over the last dozen years, t he Valley has e xperienced progress in reducing both annual average and 24

- hour PM2.5 concentrations . Between 2001 and 2013 , annual average design values declined between 30 and 35 percent at individual monitoring locations

. During this same time period , 24

- hour PM2.5 design values in the Valley have also decreased between approximately 30 and 45 percent. In addition, the number of days exceeding the 24

- hour standard decreased by about 60 to 8 0 percent.

A

- 3Even though the drought related meteorological conditions caused significant increases in 2013 PM2.5 concentrations, all sites in the Valley still attained the 24

- hour standard of 65 μ g/m3 and almost half of the sites attained the annual standard of 15 μ g/m 3

. Additional evaluations provide further i nsight into the annual and 24

- hour PM2.5 progress that has been observed. For example, as the fraction of days recording PM2.5 levels above the 24

- hour standard of 65 μ g/m 3 has decreased, there has been a corresponding increase in the fraction of days below the leve l of the annual standard of 15 μ g/m 3 . Average concentrations during the winter months have decreased, and under similar meteorological conditions, peak 24

- hour c oncentrat ions during the 2013/2014 episodes are 30 to 40 percent low er than t hey were during the 2000/2001 CRPAQS episode due to the impact of implemented emission controls

. Programs aimed at reducing NOx emissions have played an important role in reducing PM2.5 ammonium nitrate concentrations. B etween 2004 and 2012, Valley

- wi de NOx emissions decreased by 41 percent, with a commensurate reduction of about 37 percent in measured PM2.5 nitrate at the Bakersfield and Fresno monitoring sites. Based on the SJV 2015 PM2.5 Plan attainment demonstration, the 38 percent in NOx emission reductions expected from the co ntrol strategy between 2012 and 2020, are projected to decrease PM2.5 nitrate by 17 percent at the Bakersfield site and 25 percent at the Fresno site.

Control measures reducing directly emitted PM2.5 have also led to measurable reductions in PM2.5 concent rations. Between 2004 and 2012, Valley

- wide PM2.5 emissions from combustion sources decreased by 30 percent, with a concomitant reduction of 15 percent in measured carbonaceous PM2.5 at the Bakersfield site and 20 percent at Fresno site. Based on the SJV 2015 PM2.5 Plan attainment demonstration, the 28 percent reduction in PM2.5 carbon emission expected from the control strategy implementation between 2012 and 2020 is projected to decrease carbonaceous PM2.5 by 22 percent at the Bakersfield and Fresno mon itoring sites.

When will the Valley attain the PM2.5 standard with the proposed control strategy?

The U.S. EPA approved air quality modeling for the 2008 PM2.5 SIP provided the basis to predict future PM2.5 concentrations at each monitoring s ite in the S an Joaquin Valley. The attainment demonstration uses the fundamental chemistry and associated response of different PM2.5 constituents to emission controls reflected in the modeling in the 2008 PM2.5 SIP. This modeling science is coupled with 2013 design values and PM2.5 chemical composition reflecting drought impacts , along with emission reductions expected in 2020 (for the annual standard demonstration) and in 2018 (for the 24

- hour demonstration).

To assess the representativeness of the 2008 SIP modeling for capturing the dynamics and response to emission reductions for the updated attainment demonstration, ARB staff evaluated both the meteorological characteristics, as well as the chemical

A

- 4composit ion used in the two modeling efforts. The types of meteorological conditions conducive to PM2.5 formation in 2013/2014 were similar to the 2000/2001 meteorological conditions simulated in the 2008 SIP. These factors include the presence of persistent rid ges that result in warm air aloft and strong stability with limited mixing, cool morning temperatures, and low wind speeds. Although the persistence of these meteorological conditions in 2013/2014 resulted in an increased number of days with high concentr ations, the underlying meteorological factors driving elevated PM2.5 concentrations were similar to 2000/2001. In addition, the PM2.5 chemical composition used in the 2008 PM2.5 modeling was very similar to 2013, indicating common atmospheric chemistry re gimes. Therefore, the 2008 PM2.5 SIP modeling response to emission reduction, applied to 2013 design value s, provides a suitable basis for the updated attainment demo nstration.

The magnitude of emission reductions required for attainment is consistent wi th past response of Valley PM2.5 to NOx and directly emitted PM2.5 reductions

. The implementation of new reductions from California’s on

- going emission control programs will provide the majority of the emission reductions needed to attain the annual PM2.5 standard throughou t the San Joaquin Valley in 2020

. Between 2012 and 2020

, implementation of these control programs will reduce NOx emissions by 38 percent. The NO x reductions result from ongoing implementation of both new vehicle standards for passenge r and heavy

- duty diesel vehicles and equipment, as well as rules accelerating the turnover of legacy diesel fleets. Implementation of stringent requirements for new off

- road engines and in

- use off road equipment lead to further NO x reductions, along with District rules addressing stationary source NO x emissions.

In addition, directly emitted P M2.5 emissions in aggregate will be decreasing by eight percent as a result of ongoing implementation of diesel on

- and off

- road equipment measures as well as the District control measures curtailing agricultural and residential wood burning

, along with additional reductions from enhancements to the District’s commerc ial charbroiling rule slated for adoption in 2016

.

All of these measures provide the nec essary control strategy to ensure the entire Valley is in attainment of the 65 ug/m 3 24

- hour PM2.5 standard by 2018 and the 15 ug/m 3 annual PM2.5 standard by 2020

.

W hat is the impact of 2014 PM2.5 air quality data ?

The drought

- related meteorological conditions that affected PM2.5 concentrations in the San Joaquin Valley during 2013 continued into 2014. Although complete data for 2014 is not yet available, this section provides a preliminary assessment of 2014 air qu ality data in relation to the attainment demonstration.

Despite the ongoing persistence of the drought, air quality conditions in 2014 generally improved at most locations, particularly in the northern and central portions of the Valley. This is an ind ication that although drought conditions are continuing, progress is resuming as a result of ongoing emission reductions. However, because 2014 design

A

- 5values will reflect the impact of multiple years of drought, a comparison to the 2013 design values used in the attainment demonstration is expected to be mixed, with some locations recording design values that are slightly lower, and other locations recording design values that are slightly higher. Based on an assessment of the PM2.5 levels predicted for 2 020 as well as ongoing trends and analyses, consideration of 2014 design values is expected to remain consistent with the current attainment demonstration. However, ARB and the District will continue to monitor the impacts of the drought and its relations hip to future PM2.5 attainment needs.

To address the 1997 annual PM2.5 standard of 15 μ g/m 3 and 24

- hour standard of 65 μ g/m 3 , th e District adopted the 2008 PM2.5 Plan . The Plan demonstrated attainment by April 2015. U.S. EPA approved this Plan in 2011 (76 FR 41338; 76 FR 69896).

T he 2015 PM2.5 Plan specifically identifies the : 1) most expeditious date of when the Valley will attain the standard

, 2) relative efficacy of precursor emission reductions, 3) amount of emi ssions needed to attain, and 4) attainment strategy

. The Weight of Evidence (WOE) analysis provides a set of complementary a nalyses that supplement the required modeled attainment demo nstration

. A WOE approach looks at the entirety of the information at hand to provide a more informed basis for the attainment strategy. Because all methods have strengths and weaknesses, examining an air quality problem in a variety of ways offsets the limitations and uncertainty that are inherent in air quality modeling. This approach also provides a better understanding of the overall problem and the level and mix of emissions controls needed for attainment.

The U.S. EPA recognizes the importance of a comprehensive assessment of air quality data and modeling and encourages this type of broad assessment for all attainment demonstrations. In their modeling guidance, they further note that the results of supplementary analyses may be used in a WOE dete rmination to show that attainment is likely despite modeled results which may be inco nclusive. Following U.S. EPA guidance, future year modeled annual average design values that fall between 14.5 and 15.5 ug/m 3 need to be accompanied by a WOE demonstration to determine whether attainment wi ll occur. This range in model based design values reflects the uncertainty in predicting absolute PM2.5 concentrations that is inherent in air quality modeling, and therefore recognizes that an improved asse ssment of attainment can be derived from examining a broader set of analyses.

U.S. EPA recommends that three basic types of analyses be included to supplement the primary modeling analysis in the WOE approach: 1) analyses of trends in ambient air quali ty and emissions, 2) observational models and diagnostic analyses, and 3) additional modeling evaluations

. The scope of the WOE analysis is different for each nonattainment area. The level of detail appropriate for each area depends upon the complexity of the air quality problem, how far into the future the attainment deadline is, and the amount of data and modeling available. For example, less analysis is needed for an area that is projecting attainment near

- term and by a wide margin, and for which

rec ent air quality trends have demonstrated significant progress, than for areas with more severe air quality challenges

The following sections present the WOE assessment that supports the attainment demonstration for the 1997 annual and 24

PM2.5 is a complex mixture of particles and liquid droplets that vary in size and chemical composition. As a subset of PM10, particles with diameters up to 10 micrometers

, PM2.5 co mprises particles with diameter s up to 2.5 micrometers

. PM2.5 contains a diverse set of substances including elements such as carbon and metals, compounds such as nitrates, sulfates, and organic materials , and complex mixtures such as diesel exhaust and soil or dust

. Some of the particles are directly emitted into the atmosphere. Other particle s, referred to as secondary particles, result when gases are transformed into particles through physical and chemical processes in the atmosphere

Numerous health effects studies have linked e xposure to PM2.5 to increased severity of asthma attack s, development of chronic bronchitis, decreased lung function in children, increased respiratory and cardiovascular hospitalizations, and eve n premature death in people with existing cardiac or respiratory disease. In addition, California has identified particulate exhaust from diesel engines as a toxic air contaminant

– suspected to cause cancer, other serious illnesses , and premature death

. Those most sensitive to PM2.5 pollution include people with existing respiratory and cardiac problems, children

, and older adults

.

A mbient air quality standards establish the levels above which PM2.5 may cause adverse health effects. In 1997, U.S. EPA a dopted th e first set of PM2.5 air quality standards, an annual standard of 15 μ g/m 3 and a 24

- hour standard of 65 μ g/m 3 . In 2006, they tightened the 24

- hour standard to 35 μ g/m 3 , and in 2012

, they tightened the annual standard to 12 μ g/m 3

.

T he District adopted the 2008 PM2.5 Plan to address the 1997 PM2.5 standards. U.S. EPA approved the 2008 PM2.5 Plan in 20 11 (76 FR 41338; 76 FR 69896). As previously mentioned, m eteorological conditions associated with the current dr ought resulted in elevated PM2.5 levels in the Valley d uring the winter of 2013/2014 that affected annual and 24

- hour PM2.5 concentrations. As a result, the SJV will not meet the attainment deadline in the 2008 PM2.5 Plan

. In March 2015, U.S. EPA reclassified the SJV as a serious nonattainment area with a December 31, 2015 attainment deadline (80 FR 1482) and required a new SIP to address the 1997 PM2.5 standards

.

T he District also adopted the 2012 PM2.5 Plan addressing the 35 μ g/m 3 24

- hour standard

. U.S. EPA recently proposed approval of this SIP as meeting moderate area requirements. The SIP for the 12 μ g/m 3 annual PM2.5 standard is due to U.S. EPA in 2016.

a. Established monitoring network

An extensive network of PM2.5 monitors throughout the SJV provides data to assess compliance with ambient air quality standards and to study the natu re of ambient PM2.5. Many sites include multiple monitoring instruments running in parallel. Currently ten sites operate Federal Reference Monitors (FRMs), which provide regulatory data that are used to assess compliance with the federal PM2.5 standards. A dditional m onitors prov ide hourly PM2.5 measurements, a subset of which ( ten ) are Federal Equivalent Monitors (FEM), which can a lso be used to assess compliance with the standards. The FRM and FEM monitoring sites are shown in Figure 1

. The location s of these monitors are designed to capture population exposure. In addition, data collected at these monitors serve to report air q uality conditions to the public, and support forecasting for the District’s agricultural and residential burning curtailment programs. Finally, four sites have chemical speciation monitors. The speciation monitors collect samples that are further analyze d in the laboratory to determine the chemical make

- up of PM2.5.

- 9b. E xtensive field studies

T he San Joaquin Valley is one of the most studied areas in the world with an extensive number of publications in peer

- reviewed international scientific/technical jou rnals and other major reports. Since 1970, close to 20 m ajor field studies have been conducted in the Valley and surrounding areas that have elucidated various aspects of the na ture and causes of ozone and particulate matter

. A comprehensive listing of publications (reports and peer

- reviewed journal articles) is provided in Appen dix A 1

.

The first major study specifically focused on particulate matter was the Integrated Monitoring Study in 1995 (IMS

- 95), which was the pilot study for the subsequent California Regional Particulate Air Quality Study (CRPAQS) in 2000 (Solomon and Magliano, 1998). IMS

- 95 formed the technical basis for the SJV 2003 PM 10 Pla n that

was approved by the U.S. EPA in 2004 (71 FR 63642) , and the Valley was subsequently re

- designated as attainment in 2008 (73 FR 66759). CRPAQS was a key component of the technical foundation for the SJV 2008 PM2.5 Plan that U.S. EPA approved in 2011 (76 FR 41338; 76 FR 69896)

. CRPAQS findings remain relevant to the development of the current PM2.5 Plan

.

C RPAQS was a public/private par tnership designed to advance the understanding of the nature of PM2.5 in the Valley and guide development of effective control strategies. The s tudy included monitoring at over 100 sites (Figure 2 ) as well as data analysis and modeling, results of which have been published in over 60 papers and presented at national and int ernational conferences

. The field campaign was carried out between December 1999 and February 2001. CRPAQS improved our understanding of the spatial and temporal distribution of PM2.5 in the Valley, its chemical composition, transport and transformation processes , and contributing sources. More details on CRPAQS can be found at the following link: http://www.arb.ca.gov/airways/ccaqs.htm.

Fu rther fiel d studies relevant to PM2.5 include the California portion of the Ar c tic Research of the Composition of the Troposphere (ARCTAS

- 114. NATURE AND EXTENT OF THE PM2.5 PROBLEM

a. Current a ir q uality

The geography of the San Joaquin Valley

, along with large

- scale regional and local weather patterns, influence the accumulation, formation and, disp ersion of air pollutants. Covering nearly 25,000 square miles , t he Valley is a lowland area bordered by the Sierra Nevada Mountains to the east, the Pacific Coast range to the west, and the Tehachapi Mountains to the south . The mountains act as air flow barriers , with the resulting stagnant conditions favoring the accumulation of pollutants

. To the north, the Valley borders the Sacramento Valley and Delta lowland, which allows for some level of pollutant dispersion. As a result of geography and meteorology , PM2.5 concentrations are generally higher in the southern and central portions of the Valley.

To determine attainment for the annual PM2.5 standards, the corresponding design value at each monitoring site must be calculated foll owing U.S. EPA protocols. The annual design value represents a three year average of the annual average PM2.5 concentrations measured at the site. If the annual design value is equal to or below 15.0 μg/m 3 , the site attains the standard. Meteorolog ical conditions related to the prevalent drought lead to elevated PM2.5 concentrations in the SJV during the 2013/2014 winter. These elevated wintertime concentrations affected both 24

- hour and annual average concentrations.

Figure 3 shows the 2013 ann ual PM2.5 design values throughout the San Joaquin Valley (1)

. Although meteorological conditions associated with the drought lead to higher annual PM2.5 concentrations in 2013, seven sites remain below the standard

. Sites above the standard are focused in the central and southern Valley (2)

.

(1) Comparisons of PM2.5 concentrations recorded at collocated or closely located FRM and FEM monitors have shown that FEM monitors record higher concentrations (e.g. the monitors in Merced). (2) The representativeness of the Madera design value is further discussed in Appendix A 2. (3) Fresno Combined includes partial data from the old Fresno 1 st and new Fresno

- Garland sites.

The 24

- hour PM2.5 design value represents a three

- year average of the 98 th percentile of the measured PM2.5 concentrations. Depending on a site’s 24

- hour PM2.5 data collection schedule, the 98 th percentile usually correspon ds to a value between the 2 nd and the 8 th highest value. If the desi gn value is equal to or below 65 μg/m 3 , the site attains the standard. Based on 2013 24

- hour design values, all sites in the Valley attain the standard ( Figure 4 )

PM2.5 concentrations in the San Joaquin Valley exhibit a strong seasonal pattern, with highest concentrations occurring from November through February (Figure 5 ). During the winter, PM2.5 builds up over several days or weeks. These PM2.5 episodes are caused by increased activity in some emission sources and by meteorological conditions that are conducive to the build

- up and formation of PM2.5. During the winter, h igh

- pressur e weather systems over California can cause the atmosphere to become stagnant for extended periods lead ing to temperature inversions. Under normal conditions

, temperature decreases with altitude, a llowing free upward air flow dispersing emissio ns and pollutants. In contrast, a temperature inversion positions a layer of

warm er air above cooler air

, impeding upward flow of emissions and air pollutants. Often the inversion layer is lower than the mountains surrounding the Valley, trapping emissio n s and pollutants in the Valley

. Winter month PM2.5 concentrations drive the annual average concentrations.

Examination of the chemical make

- up of PM2.5 provides a nother important element in understanding the na ture of PM2.5 in the Valley and specifically identifying contributing

sources

. The pie charts in Figure 6 show the current chemical components that contribute to PM2.5 levels on an annual average basis at urban sites in the southern ( Bakersfield )

, central ( Fresno )

, and northern ( Modesto ) regions of th e Valley. Figure 7 shows the chemical components contributing to peak day PM 2.5 levels at the same sites. While the relative percentages vary, i n all cases the major components are ammonium nitrate and or ganic material (organic carbon).

Ammonium nitrate is t he largest contributor to PM2.5 levels , constituting about 40 percent of annual PM2.5 levels at the three sites. On peak PM2.5 days, the ammonium nitrate contribution is higher, approximately 50 to 65 percent. Ammonium nitrate is formed in the atm osphere from chemical reactions of NOx and am monia. Sources emitting NOx include motor vehicles and stationary combustion sources. The largest sources of ammonia are livestock operations and fe rtilizer application

. The

s tagnant, cold

, and damp conditions that occur during the winter promote the formation and accumulation of ammonium nitrate. Additional information on ammonium nitrate fo rmation can be found in section 5

. The organic matter component contributor of PM2.5 levels is largest in the central and northern portions of the Valley

. On an annual and peak day basis, o rganic matter constitutes about 30 percent of PM2.5 at Modesto and Fresno compared to less than about 20 percent at Bakersfield. A ctivities such as residential wood combustion,

c ooking, biomass burning, and direct tailpipe emissions from mobile sources contribute to the PM2.5 level organic matter component.

Ammonium sulfate contributes approximately ten percent of annual PM2.5 levels at each of the three sites. On peak days, the ammonium sulfate contribution is lower, about five percent. Ammonium sulfate is also formed in the atmosphere from SOx emitted from combustion sources and ammonia from sources like livestock operations and fertilizer application

.

Geolo gical mater ial or dust contributes approximately 15 percent to the annual PM2.5 levels at Bakersfield, while at Fresn o and Modesto it contributes about 5 percent. The geological material contribution to peak day PM2.5 levels is less than half of the contribution to annual PM2.5 levels

. Geological material is directly emitted PM2.5 and comes from dust suspended into the air by vehicle travel on roads, soil from agricultural activities, and other dust producing activities such as construction.

E leme ntal carbon contribute s less than five percent to the annual as well as the peak day PM2.5 levels at the three sites. Elemental carbon is directly emitted PM2.5 and

comes from mobile and stationary combustion sources , with significant contributions from diesel sources

a. Chemistry

As discussed previously, the cooler temperatures and higher humidity of the winter months are conducive to ammonium nitrate formation through a complex process involving NOx, ammonia, and VOCs. This occurs both at the surface and aloft, via both daytime and nighttime chemistry. U nderstanding the inter actions amongst these precursors is needed to design an appropriate and effective approach to reduce ammonium nitrate.

During the day, NO 2 is oxidized to nitric acid (HNO 3 ) . This daytime pathway also involves sunlight, VOCs, and background ozone:

O 3 OH Main oxidant is OH NO NO 2 HNO 3 Requires high sunlight, VOC rich environment

During the night, nitric acid is formed through oxidation of NO 2 (via N 2 O 5 ) by ba ckground ozone:

O 3 O 3 H 2 O Main Oxidant is Ozone (O 3 ) NO NO 2 NO 3 N 2 O 5 2 HNO 3 Favors low sunlight intensity, wet conditions

The nitric acid formed from these reactions then combines with ammonia (NH 3 ) to form ammonium nitrate (NH 4 NO 3 ):

HNO 3 + NH 3 NH 4 NO 3
Since the chemistry of NO x to nitric acid formation involves multiple steps and also depends on the availability of oxidants, only a portion of the NO x emitted ultimately forms ammonium nitrate. An early photochemical modeling study applying a box model to a typical winter episode in the San Joaquin Valley found that approximately 33 percent of the molecules of emitted NOx were converted to ammonium nitrate (Stockwell et. al. 2000). A subsequent study that modeled the January 4

- 6, 1996 episode in the San Joaquin Valley with the University California Davis/California Institute of Technology ( UCD

- CIT ) photochemical transport model found that on average, only 13 to 18 percent of the emitted NOx (expressed as NO 2 ) was converted to ammonium nitrate (Kleeman et. al. 2005). The fracti on of NOx converted varied by location, with urban regions converting little NOx to ammonium nitrate, while in remote areas up to 70 percent NOx was converted.

NOx emissions mostly originate from urban traffic and transportation corridors

, while ammonia is primarily generated from livestock oper ations and fertilizer applications.

A

- 17Analysis of CRPAQS measurements suggest that

, on average, daytime production of nitric acid in the San Joaquin Valley is relatively slow, and that nighttime production is the more dominant pathway (Lurmann et al. 2006). Although daytime mixing is limited, NOx and ammonia emitted during the day can be mixed upward where nighttime interactions can occur more regionally to form ammonium nitrate. Based on analyses conducted to c haracterize the atmospheric transport and dispersion processes during the winte r CRPAQS episodes, MacDonald et al. (2006) found that the ammonium nitrate that is formed aloft during the night is subsequently entrained into the daytime boundary layer. This was observed through a rapid rise in hourly ammonium nitrate concentrations which coincided with the growth of the surface mixed layer (Watson and Chow 2002). These mechanisms help explain the more regional distribution of ammonium nitrate that is observ ed throughout the Valley.

b. Limiting precursor concept

The amount of ammonium nitrate produced will depend on the relative atmospheric abundance of its precursors

– VOCs, NOx, and ammonia (NH 3 ). It is therefore important to understand which precursor co ntrols are most effective in reducing ammonium nitrate concentrations. In simple terms

, the precursor in shortest supply will limit how much ammonium nitrate is produced. This is known as the “limiting” precursor. The following figures provide an illustration of this concept. As shown in Figure 8 , each molecule of ammonia pairs with one NOx molecule to produce one molecule of ammonium nitrate. In this example, there are more ammonia molecules than NOx, and therefore not all of the ammonia partic i pates in forming ammonium nitrate, i.e. there is “excess” ammonia. Figure 9 illustrates the impact of reducing NOx. Here, a reduction in NOx, the less abundant precursor, leads to a commensurate reduction in ammonium ni trate. In contrast, Figure 10 illustrates that a larger reduction in the more abundant precursor, ammonia, results in no reduction in ammonium nitrate, as the ammonia reduced did not participate in ammonium nitrat e production.

. Reducing the more abundant precursor is less effective in reducing ammonium nitrate.

The following sections describe the current state of the science regarding the role of ammonia, VOCs, and NOx in ammonium nitrate formation and identify the most effective precursors for control.

c. Role of ammonia in ammonium nitrate formation

A number of different studies and analyses were evaluated to understand the role of ammonia in ammonium nitrate formation in the San Jo aquin Valley. These included: a) comparison of the magnitude of the NOx and ammonia emissi o ns inventories, b) ambient measurements of ammonia, nitric acid, and particulate ammonium; and c) photochemical modeling analyses of ammonium nitrate sensitivity to precursor emission reductions. While evaluation of emissions inventory and ambient data ca n provide indications of the relative abundance of different precursors, photochemical models provide a tool to quantitatively evaluate the impact of reducing precursor emissions on resulting ammonium nitrate concentrations.

A

- 19Emission inventory

As discussed in the limiting precursor section, the precursor in shortest supply limits the amount of ammonium nitrate formation. An evaluation of the magnitude of NOx and ammonia emissions provides a first level assessment of the relative abundance of th ese two precursors. Table 1 lists NOx and ammonia winter and annual average emissions in the current inventory for two years (2012 and 2020 ) . As Figure 1 in the limiting precursor section illustrated, in simple terms it takes one molecule of NOx and one molecule of ammonia to form one molecule of ammonium nitrate. However, due to differing molecular weights, one ton of NOx contains fewer molecules than one ton of ammonia. Therefore it is most appropriate to make an emissions inventory comparison after n ormalizing for molecular weight.

Due to emission source test procedures, most NOx emissions are expressed in terms of nitrogen dioxide (NO 2 ). Since one NO 2 molecule weighs 46 universal atomic units (u) and one NH 3 molecule weighs 17 u, one ton of NH 3 ha s 2.7 times (46 u/17 u) the number of molecules as one ton of NO 2 . Dividing the NOx emissions by 2.7 therefore provides a common basis for comparison to the ammonia emissions. On this normalized comparison basis, ammonia is significantly more abundant t han NOx, particularly in the future year (Table 1) . In addition, as noted in the chemistry section, only a portion on the NOx is ultimately converted to ammonium nitrate.

- 20Monitoring studies

Ambient measurements of precursor concentrations provide another method to investigate the relative abundance of each precursor and therefore which is most effective for control of ammonium nitrate

. Blancha rd, et al. (2000) examined two metrics using ambient data collected during the IMS

- 95 field program in the San Joaquin Valley. The first parameter was the excess of particulate ammonium plus gas

phase ammo nia over the sum of nitric acid, particulate nitrate, and particulate sulfate. The second was the ratio of particulate to total nitrate concentrations. Both metrics indicated an excess of ammonia in most IMS

- 95 samples and concluded that greater reduction s in aerosol nitrate would occur when nitric acid was reduced rather than ammonia.

Lurmann, et al. (2006) also compared ammonia and nitric acid ambient concentrations measured in the San Joaquin Valley during the winter of 2000/2001 as part of CRPAQS

. Figures 11 a nd 1 2 show the concentrations of nitric acid and ammonia measured at the rural Angiola site and at the urban Fresno site. At both sites ammonia concentrations are generally at least an order of magnitude higher than the nitric acid concentrat ions. These ammonia

- rich conditions throughout the Valley indicate that, during the winter, nitric acid rather than ammonia is the limiting precursor.

The amount of gaseous ammonia (NH3) compared to particulate ammonium (NH4) provides another indicator of how much of the ammonia is converted to ammonium nitrate and therefore whether there is excess ammonia available. These measurements were collected at a larger number of sites during CRPAQS. Figure 1 3 shows the concentrations of particulate ammonium and gaseous ammonia at three urban sites (Fresno

- 1 st , Bakersfield

- California, and Bakersfield

- residential), and three rural sites (Angiola, Pixley, and Fee dlot) measured during the 2000/2001 winter CRPAQS episode. Overall, the levels of particulate ammonium at all sites are comparable, consistent with a regional formation mechanism of ammonium nitrate. Although ammonia concentrations are higher at the rura l sites, especially at the Feedlot site, there is still a large amount of ammonia at each site beyond the amount that reacted with nitric acid to form ammonium nitrate. Again, these ammonia rich conditions indicate that nitric acid, rather than ammonia is the limiting precursor. Comparison of Ammonia and Nitric Acid Concentrations Fresno - Winter 2000/2001

Photochemical m odeling

In contrast to the previous analyses, photochemical models provide a quantitative approach to simulate the effects that emission reductions in each of the gaseous precursors would have on the predicted ammonium nitrate concentrations. A number of modelin g studies have been conducted by ARB staff and academic researchers to evaluate precursor sensitivity.

An investigation of precursor limitations for the January 4

- 6, 1996 PM2.5 episode measured in San Joaquin Valley as part of the IMS

- 95 field study use d the UCD

- CIT model. This sensitivity analysis revealed that NOx controls were the most effective control strategy to reduce PM2.5 ammonium nitr ate concentrations (Kleeman, et al. 2005). In this study, a 50 percent reduction in NOx emissions resulted in a 25 percent reduction in total nitrate, while a 50 percent reduction in ammonia emissions resulted in a 10 percent reduction in total nitrate. The results of this analysis ar e shown graphically across the entire San Joaquin Valley in Figure 1 4

. Rural Urban

In 2006, ARB staff modeled air quality during the t hr ee week winter CRPAQS episode using U.S. EPA’s Community Multiscale Air Quality (CMAQ) model with California

specific modifications and corrections ( Liang et al. 2006 ). Figure 1 5 illustrates the effects that reducing the emissions of ammonia and NOx ha ve on ammonium nitrate levels. This modeling indicated that reducing ammonia emissions by 50 percent red uced ammonium nitrate by less than 5 percent. On the other hand, reducing NOx emission by 50 percent reduce d ammonium nitrate concentrations by approx imately 35 percent. This analysis

, therefore

, indicate d that reducing NOx emissions was the most beneficial control strategy to reduce ammonium nitrate.

In another study based on sensitivity analyses using CMAQ

- Madrid simulations of the December 2000 CRPAQS episode, Pun et al. (2009) found that a 50 percent reduction in NOx emissions reduced ammonium nitrate by approximately 50 percent at rural sites and between 30

- 45 percent at Ba kersfield. As shown in Figure 1 6 , a 50 percent reduction in ammonia emissions did not have a significant effect on ammonium nitrate concentrations at urban sites. At the rural site of Angiola, ammonium nitrate concentrations decreased between 10 and 25 percent. However, such reductions in ammonium nitrate occurred only towards the end of the episode, when PM2.5 concentrations at the rural site mea sured approximately 80 μg/m3 and concentrations at the urban site recorded over 110 μg/m3 (Figure 9). At the end of the episode, PM2.5 concentrations at Bakersfield peaked at 155 μg/m3 (January 5, 2001). For the most part, the San Joaquin Valley does no t currently reach those PM2.5 concentration levels. Figure 1 7 shows a comparison of PM2.5 concentrations during the CRPAQS and the 2013/2014 PM2.5 episodes from November 1 through February 5 when the highest PM2.5 concentrations were recorded in the last 1 0 years. In addition, Pun et al. noted that under wintertime conditions, nitric acid concentrations in the SJV were small and therefore ammonium nitrate formation was generally limited by the availability of nitric acid rather than ammonia. -60% -50% -40% -30% -20% -10%

- 26In 2012, as part of the emission control strategy development for the San Joaquin Valley PM2.5 Plan for the federal 35 μ g/m 3 24

- hour standard, ARB staff conducted modeling using CMAQ to simulate the response of PM2.5 concentrations to reductions in PM2.5 precursors in 2019 throughout the Valley (SJV 2012 PM2.5 Plan; Chen, et al. 2014). Simulations were run during the first and fourth quarters (January

– March and October

- December) of 2019. In the San Joaquin Valley, high PM2.5 values in the first and fourth quarters drive the annual average concentrations to be over the annual PM2.5 standard.

Per the analysis above, Table 2 c ompares the modeled effect on the 2019 24

- hour PM2.5 design value obtained at each monitoring site from a 25 percent reduction in the specified precursor. The information is normalized to reflect the reduction in design value per ton of each precursor red uced. Consistently, direct PM2.5 reductions have the most benefit, followed by NOx reductions. Reductions in ammonia and SOx provide much smaller benefits. While on an annual average basis, SOx emission reductions are quite effective in reducing PM2.5 c oncentrations, during the winter they are less effective since ammonium sulfate is more prevalent during the non

- winter months. Reductions in VOCs result in s mall disbenefits at most sites. On a relative basis, V alley

- wide reductions in ammonia are appro ximately nine times less effective than NOx and over 35 times less effective than PM2.5.

Ch en et al. (2014) reported that i n the San Joaquin Valley, 2019 24

- hour PM2.5 design values showed strong responses to emission reductions in directly emitted PM2.5 and NOx. At Bakersfield

- California, a 50 percent reduction in PM2.5 emissions and NOx emissions decreased the 2019 24

- 28decreased the design value by approximately 4 percent. In further detail, a 50 percent reduction in NOx emissions resulted in an approximate 42 percent drop in nitrate concentrations at Bakersfield, comparable to the reductions reported by Pun et al. (2009). Reductions in SOx emissions had a minor effect on the PM2.5 24

- hour design values , since ammonium sulfate is a minor component of winter

- time PM2.5 levels

. VOC reductions slightly increased PM2.5 concentrations. The authors noted similar responses to PM2.5 precursors at Fresno. On average, at the other seven monitoring sites in the San Joaquin Valley, a 50 percent reduction in NOx emissions lowere d PM2.5 approximately 23 percent, while a 50 percent reduction in ammonia emissions lowered PM2.5 by 5 percent. The authors conclude these results demonstrate that in the San Joaquin Valley in 2019, ammonium nitrate formation will be ge nerally limited by nitric acid rather than ammonia.

Due to the highest PM2.5 concentrations occurring in Kern County, ARB staff conducted specific model sensitivity runs to evaluate the benefits of emission reductions focused on the nonattainment sub

- area as part of the SJV 2012 PM2.5 Plan . The Kern County sensitivity runs demonstrated that one ton per day of PM2.5 reductio ns provided a 1 μ g/m 3 improvement in the Bakersfield

- California 2019 24

- hour PM2.5 design value; one ton pe r day of NOx reductions pro vided for a 0.12 μ g/m 3 improvement while one ton per da y of ammonia reductions provided for a 0.02 μ g/m 3 improvement and one t on per day of VOC reductions had no effect.
These modeling results, along with the findings from past modeling and monitoring

s tudies continue to highlight that reductions in directly emitted PM2.5 emissions provide the most bene fit, followed by NOx emissions in reducing PM2.5 concentrations and making progress towa rds attainment. A mmonia emission reductions are approximately

an order of magnitude less effective. VOC emission reductions do not provide air quality benefits. T aken together, the emission inventory, monitoring data, and precursor sensitivity analyses all indicate that in the San Joaquin Valley, NOx, rather than

ammo nia is the limiting precursor for ammonium nitrate formation.

A

- 29d. Role of VOC in ammonium nitrate formation
A number of studies have also been examined regarding the role of VOCs in ammonium nitrate formation. These include both monitoring studies conducted as part of CRPAQS , as well as studies that used differing types of air quality modeling to quantitatively assess the expected change in ammonium nitrate to hypothetical VOC reductions.

Monitoring studies

As previously mentioned, t here are t wo primary pathways through which ammonium nitrate can form. During the day, NO 2 is oxidized to nitric acid. Nitric acid then reacts with ammonia to form ammonium nitrate. This daytime nitric acid formation pathway involves sunlight, VOCs, and backgroun d ozone. During the night, nitric acid is formed through oxidation of NO 2 (via N 2 O 5 ) by background ozone, which then also reacts with ammonia to form ammonium nitrate. Studies by Pun et al. (1998, 2004) suggested that the daytime pathway may be important and therefore the formation of ammonium nitrate would be sensitive to changes in VOC emissions. However, other studies (Lurmann et al., 2006), suggest that on average, daytime production of nitric acid in the San Joaquin Valley is relatively slow and tha t nighttime production of ammonium nitrate aloft, which then mixes to the surface after sunrise could explain the observed homogeneous patterns of ammonium ni trate in the Valley. Ying et al. (2009) also theorized that the ozone concentration aloft in the San Joaquin Valley is predominantly due to the regional background and does not vary significantly with surface

- level VOC emissions. Therefore, nighttime ammonium nitrate formation in the San Joaquin Valley would not be sensitive to VOC reductions.

W hile the monitoring studies cited above provide evidence that the VOC pathway may be important at times, these studies do not provide quantitative information about the overall role of and cannot be used to evaluate the benefits of

, VOC controls. Rather, mode ling studies are more appropriate to assess the overall impact of precursor controls.

Photochemical m odeling

Sta ff reviewed the results of six modeling studies containing information on the significance of VOC controls in reducing ammonium nitrate in t he San Joaquin Valley

. While the results of the earliest studies were mixed, later studies provide generally consistent results regarding the role of VOCs. In assessing the potential benefits of VOC controls it is important that significance be interpret ed in the context of California’s overall control program with its strong focus on NOx control to achieve benefits for both PM2.5 and ozone.

Two early studies used simplified box modeling to explore the sensitivity of ammonium nitrate to VOC and NOx red uctions. One of the two studies simulated a typical winter episode (Stockwell et al., 2000) and found that decreases in VOC emissions had little effect. The second study (Pun and Seigneur, 2001) simulated winter conditions during

A

- 30the 1996 IMS

- 95 pilot st udy around the Fresno area. The study found that ammonium nitrate formation decreased with VOC emission reductions, but increased with NOx reductions. Pun and Seigneur (2001) theorized that reducing NOx could lead to higher concentrations of the hydroxyl radical ( OH ) and increase the overall rate of nitrate production, despite the reductions in NOx. However, the box modeling approach used ha d a number of limitations, including lack of transport into/out of the box, robust vertical transport, and use of an older chemical mechanism. In addition, the VOC emissions were increased by a factor of two to improve model performance. As such, the box modeling did not fully represent the complete scope of atmospheric variations and has limited usefulness in assessing the responsiveness to VOC controls.

Subsequent modeling sensitivity studies for the same winter episode were conducted with the UCD

- CIT m odel, an advanced research grade modeling system (Kleeman et al., 2005). The authors concluded that NOx emission controls are more effective in reducing PM2.5 nitrate concentrations in the San Joaquin Valley. Summary study results indicate that on averag e, large reductions in VO C emissions (on the order of 50 percent) reduced PM2.5 nitrate concentrations by approximately 17 percent. However, to evaluate the significance and effectiveness of VOC controls in the context of control strategy design, the stud y’s isopleths of PM2.5 nitrate response to combined NOx/VOC emission reductions provide more in

- depth information.

Figures 19 (a) and 2 0 (a) show that, based on the shapes of the graphs, NOx controls are the most effective approach to reduce PM2.5 nitrate concentrations at Fresno and at the location with the highest modeled PM2.5 nitrate concentration (grid location

- 85 km Northing, 90 km Easting) respectively. Once NOx controls are taken into consideration, VOC emission reductions produce essentially no benefit , and in some instances may actually lead to an increase in PM2.5 nitrate concentrations. For example, as illustrated in Figure 19 (a) for Fresno, after considering an approximately 70 percent reduction in NOx emissions resulting from existing and proposed controls, reductions in VOC emissions to any level would not decrease PM2.5 nitrate concentrations. Furthermore, at grid location

- 85 km Northing, 90 km Easting (Figure 2 0 (a)), any level of VOC emission reductions would actually cause an increas e in nitrate concentrations . Nitrogen

- containing molecules such as PAN can act as temporary sinks for nitrogen dioxide ( NO 2 ) . When VOCs are controlled, the reduced availability of certain radicals

, which are generated from VOCs

, reduces the amount of NO 2 that is sequestered, thereby increasing the availability of NO 2 and enhancing ammonium nitrate formation (Meng et al., 1997)

Three additional modeling studies investigated the two

- week winter episode of 2000

- 2001 that occurred during the CRPAQS field study.

In the first study, preliminary data from modeling of this CRPAQS winter episode conduc ted using the Lagrangian form of the UCD

- CIT model qualitatively confirm that NOx control is the most efficient method to reduce nitrate concentrations (Kleeman, M.J., personal communication, May 2008). Figure 2 1 illustrates the response of PM2.5 nitrate concentrations to NOx and VOC emission reductions at a rural (Angiola) and an urban (Fresno) site on December 31, 2000. Again, based on their shapes, these graphs show that NOx controls are the most effective app roach to reduce PM2.5 nitrate

A

- 33concentrations. Once NOx controls are taken into consideration (approximately 7 0 percent reduction in NOx emissions), reductions in VOCs of up to 30 percent produce basically no benefit (Fresno). Furthermore , at some locatio ns (Angiola) any VOC emission reductions may actually lead to an increase in PM2.5 nitrate concentrations.

- day back tra ject ory simulation for December 31, 2000. Units are in μg/m 3 . (Source: Kleeman, M.J., personal communication, May 2008)

.

A second study conducted simulations of the two

- week CRPAQS episode with the CMAQ photochemical model (Livingston, et al., 2009). The study consisted of two simulations. The first was a baseline scenario using a preliminary emissions inventory. This simulation showed that 50 percent reductions in anthropogenic VOC and NOx emissions had similar effects in reducing ammonium nit rate (about 20 percent each). A second simulation was conducted using an updated emission inventory representing a more accurate spatial distribution of total ammonia emissions (referred to as “Vehicle NH 3 ” scenario, per Livingston, P., personal communication, January 19, 2011). This second 50 percent VOC reduction simulation showed a much lower response to VOC controls. T he response was lowered to a 12 percent reduction in ammonium nitrate, with a corres ponding increase in responsiveness to NOx control of 38 percent reduction in ammonium nitrate . These results are consistent with those found by Kleeman et al., 2005.

A third study modeled one week of the CRPAQS episode using a version of CMAQ with

a more advanced chemical mechanism (CMAQ

- Madrid) (Pun et al, 2009). In contrast to the earlier Pun study using a simplified box modeling approach, this later work found

A

- 34that on average, nitrate was most sensitive to reductions in NOx emissions. While isopleths were not provided, the time evolution of nitrate and PM2.5 mass to VOC response illustrated in Figure 2 2 provides further detail s regarding the efficacy of VOC control. The response of nitrate to a 50 percent reduction in VOC emissions increased as PM2.5 levels rose during the episode. In urban areas, a 50 percent reduction in anthropogenic VOC emissions caused small reductions in nitrate, on the order of 10 percent

, on the modeled days when 24

- hour PM2.5 concentrations measured over 100 μg/m 3 at urban s ites and above 65 μg/m 3 in rural areas.

The difference in the VOC response on the days with the higher PM2.5 concentrations as compared to those days with lower concentrations may be due to a difference in the chemical formation regime for nitrate. In ge neral, there is sufficient background ozone to generate enough free radicals to initiate and propagate the chemistry of nitrate formation (Ying et. al, 2009). However, on days with high PM2.5 concentrations, the daytime photochemistry may have contributed to a rapid increase in nitrate, resulting in higher VOC and NOx sensitivity. It does not appear that VOCs contributed significantly to the free radical budget on the simulated days mainly because rapid increases in ozone were not observed. The effect of VOC levels on nitrate formation may also have a diurnal pattern since the hydroxyl and hydroperoxyl radical levels are high during the daytime and negligible at night. In addition, more reactive VOCs react quickly during the day and there is a minimal ca rry over to the next day. Therefore, it is reasonable to assume that the higher response to VOC and NOx at higher PM2.5 concentrations may be due to the nitrate formation mechanism rather than to PM2.5 accumulation due to the length of the episode.

Ove rall, nitrate was only responsive to a 50 percent reduction in VOCs at PM2.5 levels that are no longer reache d in the San Joaquin Valley. Currently, the 24

- hour PM2.5 design value in the Valley is 65 μg/m 3 recorded at Bakersfield and the rest of the Valley records 24

- hour design values between 30 μg/m 3 and 63 μg/m 3

. Given the current levels of PM2.5, we believe the Valley is now in a nitrate chemical formation regime that is less responsive to VOC controls

As mention earlier, i n 2012, as part of the emission control strategy development for the San Joaquin Valley Plan for the federal 35 μ g/m 3 24

- hour standard, ARB staff conducted modeling using CMAQ to simulate the response of PM2.5 concentrations to reductions in PM2.5 precursors in 2019 throughout the Valley (SJV 2012 PM2.5 Plan; Chen et al., 2014). Table 2 provided the modeled effect on th e 2019 24

- hour PM2.5 design value obtained at each monitoring site from a 25 percent reduction in the specified precursor. The information is presented normalized to reflect the reduction in design value per ton of each precursor reduced. Consistently, direct PM2.5 reductions have the most benefit, followed by NOx reductions. Reductions in VOCs result in small disbenefits at most sites. V alley

- wide reductions in PM2.5 are approximately four times as effective as NOx. In contrast, reductions in VOCs re sult in either no impact of very small disbenefits.

Figure 2 3 again shows the results of modeling sensitivity runs plotted on isopleth diagrams for Bakersfield

- California site with NOx vs VOCs highlighted . Reductions in NOx have significant benefits in reducing PM2.5 design values. On the other hand, reducing VOCs leads to very small increases in the design value because these

Chen et al. (2014) reported that at Bakersfield

- California, a 50 percent reduction in anthropogenic VOC emissions in the Valley slightly increased the 2019 24

- hour PM2.5 design value by 0.2 μ g/m 3 . At this site, VOC emission reductions lead to slightly hig her ammonium nitrate concentrations and slightly lower secondary organic carbon.

- January 7, 2001 winter period in the San Joaquin Valley. The authors generated isopleths diagrams for December 31, 2000 at Bakersfield, Fresno, and the San Joaquin Valley regional

aver age, where 24

- hour average PM2.5 nitrate concentrations are presented at various levels of NOx and VOC emission reductions. Valley

- wide emission trends for 2000, 2005, 2010 and 2015 expressed as a fraction of 2000 were superimposed on the isopleth diagram s ( Figure 2 4 ) . Results show that at each five

- year interval point, greater reductions in PM2.5 nitrate are achieved through NOx controls rather than VOC controls. The authors explain this response is reasonable, because background ozone transported into the San Joaquin Valley from the global background is the main oxidant during the winter stagnation episodes in the valley.

Dots represent emissions in 2000, 2005, 2010, and 2015. The projected 2020 emissions are less thatn 40 percent of the 2000 emissions and are therefore not shown on the graph. (Source: Chen et al., 2014, Figure 5, pg. 189).

Taken together, these air quality modeling studies indicate that in the San Joaquin Valley, NOx, rather than VOCs, is the limiting precursor for nitric acid and subsequent

A

- 38ammonium nitrate formation, and reductions in V OCs result in small increases in PM2.5.

6. SECONDARY ORGANIC AEROSOL FORMATION

VOC emissions also have the potential to contribute to secondary organic aerosols (SOA). While these components contribute to observed PM2.5 concentrations in the San Joaquin Va lley to a small degree, the weight of evidence indicates that anthropogenic VOC is not a significant contributor to PM2.5.
SOA form when intermediate molecular weight VOCs

, emitted by anthropogenic and biogenic sources

, react and condense in the atmosphere to become aerosols. In addition, lighter VOCs participate in the formation of atmospheric oxidants which then participate in the formation of SOA. T he processes of SOA formation are complex and have not been fully characterized

. The apportionment of PM2 .5 organic carbon to primary and secondary components is a very active area of current research.

Us ing the UCD

- CIT model, Chen et al. (2010) investigated the apportionment of PM 2.5 organic carbon for the 2000/2001 CRPAQS episode. From the total predicted PM 2.5 organic carbon in the urban Fresno and Bakersfield areas, six percent and four percent

were SOA, respectively, while in the rural Angiola area, 37 percent was SOA. The major SOA precursors of secondary organic aerosol were long

- chain alkan es followed by aromatic compounds. The sources of these precursors were solvent use, catalyst gasoline engines, wood s moke, non

- catalyst gasoline engines, and other anthropogenic sources, in that order.

In contrast, o n an annual average basis, secondary organic aerosols derived from anthropogenic VOC emissions account for only one to two percent of the annual total PM2.5 concent rations throughout the Valley. ARB air quality modeling exercises conducted a s part of the SJV 2008 PM2. 5 Plan attainment demons tration analysis using the CMAQ model showed that primary PM2.5 emissions are the main contributor to organic aerosols and SOA contribute to only a small extent. Further more, as illustrated in Figure 2 5

, SOA are mostly formed during the summertime, when t otal PM2.5 concentrations are low, and are mainly derived fr om biogenic emission sources. On an annual average basis, SOA derived from anthropogenic VOC emissions are a small part of the o rganic aerosol concentrations (three to five percent).

. Daily contributions to organic aerosol concentrations in Bakersfield in 2000 modeled with CMAQ: Primary organic aerosols (PA), secondary aerosols formed from biogenic VOC emissions (SB) and secondary aerosols formed from anthropogenic source VOC emissio ns (SA). Units are μg/m 3

.

As part of the CRPAQS study, simulations of a wintertime episode conducted using CMAQ

- Madrid, a model with an enhanced secondary organic aerosol formation mechanism, also found that organic aerosol concentrations were dominate d by directly emit ted (primary ) emissions. The study found that, because of the dominance of prima ry PM2.5 organic matter , a 50 percent reduction in anthropogenic VOC emissions has limited effects on the modeled PM2.5 organic matter (Pun, et al., 2009).
These study results show that for secondary organic aerosols, further VOC reductions would have very limited effectiveness in reducing PM2.5 concentrations. VOC reductions also result in small increases in PM2.5 overall, due to the fact that they increase nitrate. BAC

- 407. SECONDARY AMMONIUM SULFATE FORMATION

Sulfur oxide s (SO x ) emitted from stationary and mobile combustion sources mostly as sulfur dioxide (SO 2 ) are oxidized in the atmosphere to ultimately form sulfuric acid (H 2 SO 4 ). Sulfuric acid then combines with ammonia to form ammonium sulfate:

H 2 SO 4 + 2 NH 3 (NH 3 ) 2 SO 4

Table 3 lists S Ox and ammonia winter and annual average emissions in the current inventory for two years (2012 and 2020). As shown in the above equation, in simple terms it takes one molecule of SOx and two molecule s of ammonia to form one molecule of ammonium sulfate. However, due to differing molecular weights, one ton of S Ox contains fewer molecules than one ton of ammo nia. Therefore it is most appropriate to make an emissions inventory comparison after normalizing for molecular weight

Since one SO 2 molecule weighs 64 u and one NH 3 molecule weighs 17 u, one ton of NH 3 has 3.8 times (64 u/17 u) the number of molecules as one ton of SO 2 . As one molecule of SO 2 reacts with 2 molecules of NH 3 , dividing the SO 2 emissions by 1.9 there fore provides a common basis for comparison to the ammonia emissions. On this normalized comparison basis, ammonia is approximately 80 times mor e abundant than S Ox

. Thus

, SOx emissions are the limiting precursor for ammonium sulfate formation.

- 418. EMISSION SOURCES OF ANNUAL AVERAGE PM2.5

a. Emission i nventory

Emission inventories provide emission estimates for sources of di rectly emitted (primary) PM2.5 and of each of the gaseous precursors of secondary PM2.5 (NOx, SOx, and ammonia)

. Table 4 lists the main PM2.5 components and links them to their largest em ission sources based on San Joaquin Valley emission inventory data for 2012, the base year for the 2015 PM2.5 Plan. VOC emission are not listed, since, as discussed in sections 5d and 6

, o verall, VOC emission reductions have no effect on PM2.5 concentrations in the Valley. Emission sources are lis ted in descending order of magnitude

.

As described in section 4c

, ammonium nitrate is the main PM2.5 component, contributing about 40 percent of PM2.5 levels

. It is formed in the atmosphere from reactions of NOx and ammonia emissions . Heavy

- duty diesel vehicles (trucks) are the largest source of NOx emissions , followed by farm equipment, off

- road equipment, light

duty vehicles, trains, and residential fuel combustion. Ammonia is primarily emitted from livestock husbandry and fertilizer application. Ammonium sulfate, formed in the air from reactions of SOx an d ammonia emissions , contributes about 10 to 15 percent to PM2.5 levels

. SOx is mostly emitted from the manufacturing of chemicals and glass related products and fuel combustion sources in oil and industrial manufacturing processes. Organic carbon, which contributes about 20 to 35 percent to PM2.5 levels

, and elemental carbon, which contributes about two to five percent of PM2.5 levels , a re directly emitted, with key sources being residential fuel combustion, diesel trucks, cooking, and managed burning an d disposal. Geological material contributes about five to 15 percent of the PM2.5 mass and is directly emitted from activities generating dust, such as farming operations and on

- road and off

- road vehicle travel, as well as wind

blown dust.

While emissi on inventories provide a broad overview of Valley wide and county level sources, additional methods using ambient data and source apportionm ent modeling provide supplemental information on the sources directly impacting individual monitoring sites. The fo llowing sections describe these analyses.

Source receptor models ( also known as observational models) can be used to determine the relative importance of the different types of PM2.5 emission sources at individual monitoring sites . The Chemical Mass Balance (CMB) model statistically relates measured chemical species of ambient PM2.5 to the chemical species emitted by diverse sources. The Positive Matrix Factorization (PMF) statistical model distinguishes correlation patterns among measured PM2 .5 species to identify sour ces.

Chemical Mass Balance Modeling

Source contributions to annual average PM2.5 concentration s at Bakersfield

- California (BAC) and Fresno

– 1 st Street ( FSF) were es timated by applying the CMB model version 8.2 to individual PM2.5 samples using PM2.5 source profiles developed during previous studies. The PM2.5 samples were from between 2008 and 2010. Per U.S. EPA guidance, b etween 2007 and 2009

, the carbon collection and analysis method was changed to improve comparability with the rural Interagency Monitoring of Protected Visual Environments (IMPROVE) PM2.5 carbon data. Since t he new carbon method started operating in May 2007 at Bakersfield and in April 2009 at Fresno, the CMB analysis relied on 200 8

- 2010 data from Bakersfield and 2010 data from Fresno. Appendix A 3 describes this CMB analysis in further detail.

a. Annual PM2.5 trends

On an annual average basis, PM2.5 air quality has improved over the last dozen years. Figure 28, shows annual design value (1) trends at sites in the northern (e.g., Modesto), central (e.g., Fresno

- 1 st /Garland ) and southern regions (e.g., Bakersfield

- California).

The Valley was nearing attainment of the annual standard through 2012, with only a few sites recording design values over the standard

. However, due to meteorological conditions associated with the drought PM2.5 concentrations during the 2 013/2014 winter increased , causing 2013 design values to go over the standard at more sites in the Valley.

Despite the increase in 2013, the Valley is still seeing overall progress. B etween 2001 and 2013 , annual design values declined between 1 0 and 35 percent. A bout half of the sites in the Valley attain the standard in 2013, with the highest remaining levels in the central and southern regions , where design values are about five to 20 percent over the standard.

(1) The design value

-- the metric used to determine compliance with the standard

-- represents the average of three consecutive annual averages of the PM2.5 concentrations measured at a specific site (e.g. the 2013 PM2.5 annual design value is the average of the 2011, 2012, and 2013 annual average PM2.5 concentrations).

As illustrated in Figure 29

, over the long

- hour PM2.5 design values also show a downward trend. The most pronounced progress occurred b etween 2001 and 2003. Extensive wildfires occurred during the summer of 2008 in Northern California. These wildfires impacted the 2008, 2009, and 2010 design val ues throughout the Valley, with greater impact in the northern Valley. Overall

, between 2001 and 2013 , the 24

- hour PM2.5 design values in the Valley h ave decreased between 15 and 4 5 percent. In 2013, all sites in the Valley attained the standard.

Lo oking at the number of days with measured PM2.5 concentrations over the 65 μ g/m 3 and 35 μ g/m 3 standard s provides another way to assess PM2.5 impacts

. Over the long term

, between 1999 and 2013 , the number of days exceed ing the 65 μ g/m 3 standard decreased by about 6 0 percent at the Bakersfield

- California site and by about 80 percent at the Fresno

- Garland site ( Figure 3 0 )

. Within the same period, the number of days over the 35 μ g/m 3 decreased by about 30 percent at the Bakersfield

- California site and by about 40 percent at the Fresno

- 1 st site ( Figure 3 1 ). The increase in th e number of exceedance days in 2013 compared to 2012 was due to the severe meteorological conditions during the winter of 2013

- 2014 related to the drought. T he Valley experienced similar ly severe meteorological conditions during the 1999

- 200 0 and 2000

- 2001 winters. T he total number of exeedance days , however, was much higher during these earlier years , providing evidence that the emission reductions achieved in the Valley have resulted in PM2.5 air quality improvement. 0 10 20 30 40 50 60 70 80 90 100PM2.5 Design Value (ug/m3)

Comparing the change in the frequency distribution of 24

- 2012 three

- year periods at Bakersfield and to the 2011

- 2013 period at Fresno and Modesto. Trends in individual PM2.5 chemical components , as well as emission inventory trends were evaluated to highlight the main chemical components leading to the progress in PM2.5 air qua l ity a nd to evaluate the response to State and District control programs.

Speciation monitors in the SJV collect data on PM2.5 chemical composition

. Figures 39, 40, and 41 illustrate the three

- year average trends in the individual PM2.5 components at Bakersfie ld, Fresno, and Modesto. Between 2007 and 2009, the carbon collection and analysis method was changed to improve comparability with the rural IMPROVE PM2.5 carbon data. Thus, f or trend analyses, the total carbon compounds mass was estimated as the difference between the measured PM2.5 mass and the inorganic components mass

. Ammonium nitrate, ammonium sulfate, and carbon compounds are th e major constituents of PM2.5 levels

. On an annual average basis, concentrations of the se key constituents have all shown significant decreases. Ammonium nit rate concentrations in the Valley declined about 25 to 35 percent between 2004 (2002

- 20014 average) and 2013 (2011

- 2013 average) . During the same tim e

- frame, concentrations of ammonium sulfate declined about 20 to 36 percent and other, including organic and elemental carbon declined about approximately 1 5 percent. The most significan t declines occurred between 2004 and 2005, and again between 2008 and 2011

Selected compounds measured in the atmosphere can serve as chemical markers for specific sources. Since 2007, ARB conducts measurements of levoglucosan, a chemical marker of wood smoke , at the Modesto and Visalia monitoring sites. Figure 4 2 illustrates the trends in winter time levoglucosan concentrations at these two sites. The data are presented as three

- year averages (e.g ., the 2009 concentration represents the 2007

- 2009 average concentration) . Between 2009 and 2013 , levoglucosan decreased by about ten percent at Visalia, with steady decrease until 2012 and a marked increase in 2013. On the other hand, levoglucosan level s at Modesto stayed approximately

cons tant between 2009 and 2012 and increased by approximately 35 percent in 2013. The severe drought conditions led to the higher levoglucosan concentrations recorded in 2013

. The District Rule 4901, which restricts residential wood

- burning on days when high concentr ations of PM2.5 are predicted, as well as the District’s stringent smoke management program under which agricultural burning is prohibited on those same days

, led to the observed reductions in levoglusoan.

- 58f. Emission i nventory trends

Reductions in PM2.5, NOx and SOx emissions are key to effectively reducing PM2.5 concentrations

. Figure 4 3 illustrates annual emission trends in the San Joaquin Valley air basin from 2000 through 2013 (1) for PM2.5 and the two key precursors

.

• NOx emissions have decreased by 284 tons per day (tpd) or 47 percent. Major reductions occurred in emissions from heavy

- duty diesel trucks, stationary combustion sources, and other mobile sources (e.g., farm and off

- road equipment, trains)

• Direct PM2.5 emissions decreased by 27 tpd or about 30 percent. Major reductions occurred in emissions from residential wood combustion, mobile sources, such as heavy

- duty diesel trucks and off

- road equipment, and entrained dust.

• SOx decreased by 15 tpd or about 65 percent. Major reductions occurred in emissions from stationary fuel combustion sources and in dustrial processes.

The combined downward trends in PM2.5 components and emissions of PM2.5, NOx, and SOx indicate that the ongoing control program has had substantial benefits in improving air quality in the SJV and that further emission reductions in th e future are expected to provide continuing p rogress towards attaining the annual PM2.5 standard.

a. NOx c ontrol

Programs aimed at reducing NOx emissions have played an important role in reducing nitrate c oncentrations and, consequently

, overall PM2.5 concentrations in the Valley

. As discussed in section 5, previous studies have identified NOx as the limiting precursor for ammonium nitrate formation. As a result, NOx emissions and PM2.5 nitrate levels track each other over the years. Trends in estimated NOx emissi ons , as well as monitored ambient concentrations

, are compared with trends in measured PM2.5 nitrate concentratio ns. As illustrated in Figure 4 4 , between 2004 and 201 2

, Valley

- wide NOx emissions decreased by about 41 percent

, wit h a commensurate reduction of about 37 percent in PM2.5 nitrate concentrations at the Bakersfield and Fresno sites

. Furthermore, the reductions in NOx emissions were also reflected in the corresponding reduction in the ambient gaseous NOx concentrations. Figures 4 5 and 46 show a strong correlation between trends in PM2.5 nitrate concentrations and ambient NOx concentrations at the Bakersfield and Fresno sites. Between 2004 an d 2012

, concentrations of PM2.5 nitrate decreased about 37 percent and ambient NOx dec reased between 35 percent and 40 percent

Programs geared at reducing PM2.5 emissions from combustion sources have played an important role in reducing overall PM2.5 concentrations in Vall ey. As illustrated in Figure 47, between 2004 and 2012 , Valley

- wide combustion PM2.5 emissions decreased by approximate ly 30 percent with a concomitant 15 percent reduction in measured PM2.5 carbon com pounds at the Bakersfield site and 20 percent reduction at the Fresno site . The most significant declines in PM2.5 carbon compounds occurred between 2004 and 2005 and again between 2008 and 2012

. The severe drought conditions in 2013 caused the observed increase in PM2.5 carbon compounds at Fresno.

.

Reductions in combustion sources include the implementation of District Rule 4901, which restricts residential wood

- burning on days when high concentr ations of PM2.5 are predicted. In addition, as part of the District’s stringent smoke management program, agricultural burning is prohibited on those same days. Through a series of Rule 4901 amendments, the PM2.5 threshold for calling no

- burn days was established in 2003 at 65 μg/m 3 an d subsequently tightened to 30 μg/m 3 in 2008. Before the 2014/2015 winter, the District lowered the no

The District staff developed a statistical model to quantify PM2.5 reductions and evalua te air quality improvements attributable to the 2003 and 2008 amendments to Rule 4901. The District used generalized linear model techniques with logarithmic transformations based on the relationships between meteorology and PM2.5 concentrations that exis ted prior to the 2003 Rule 4901 amendments. Results from this model were used to evaluate rule effectiveness through the winter of 2013

- 2014.

Using daily and hourly observed PM2.5 concentrations as dependent variables with meteorological parameters such as wind speed, temperature, and stability as independent variables, statistical relationships of PM2.5 to meteorology were developed for the winters of 2001

- 2002 and 2002

- 2003. These statistical relationships made it possible to predict daily and evening PM2.5 levels in the period following the 2003 and 2008 rule amendments, which were then compared to observed PM2.5 concentrations to evaluate air quality improvements. A consistent pattern of model

- predicted values being higher than what was actually obs erved provides statistical evi dence that a control measure, e.g. , wood

- burning curtailments, was responsible for the changes in PM2.5 concentrations

. This statistical modeling indicates that significant improvement has been made after the 2003 and 2008 Rule 4901 amendments in Modesto, Fresno and Bakersfield ( Figure 52 ) . To date, there has been an average improvement of 16 μg/m3 (40%) in the 24

- hour average PM2.5 level since the 2003 and 2008 amendments. This improvement is exemplifie d in PM2.5 concentrations measured during the evening hours of 8:00 p.m. to 12:00 a.m., where the average concentrations have improved by 28 μg/m3 (4 5%) over the same time period.

The U.S. EPA approved air quality modeling for the 2008 PM2.5 SIP provided the basis to predict future PM2.5 concentrations at each monitoring s ite in the San Joaquin Valley. The attainment demonstration uses the fundamental chemistry and associated response of different PM 2.5 constituents to emission control s reflected in the modeling in the 2008 PM2.5 SIP. This modeling science is coupled with air quality data reflecting 2013 design values and PM2.5 chemical composition, along with emission reductions expected in 2020 (for the annual standard demonstration) and in 2018 (for the 24

- hour demonstration).

The implementation of new reductions from California’s on

- going emission control programs will provide the majority of the emission reduct ions needed to attain the annual PM2.5 standa rd throughout t he San Joaquin Valley in 2020. Between 2012, the base year used in the photochemical modeling attainment demonstration and 2020, implementation of these control programs will reduce NOx emissions by 38 percent. The NO x reductions result fr om ongoing implementation of both new vehicle standards for passenger and heavy

- duty diesel vehicles and equipment, as well as rules accelerating the turnover of legacy diesel fleets. Implementation of stringent requirements for new off

- road engines and i n

- use off road equipment lead to further NO x reductions, along with District rules addressing stationary source NO x emissions. The weight of evidence analysis has demonstrated that prior reductions in NOx have resulted in commensurate reductions in ambi ent concentrations of nitrate.

In addition, directly emitted PM2.5 emissions in aggregate are decreasing by eight percent. PM2.5 emission reductions result from ongoing implementation of diesel

on

- and off

- road equipment measures as well as the District ’s recently strengthened rule for wood

- burning fireplaces and heaters. These measures, along with additional reductions from enhancements to the District’s commercial charbroiling rule slated for adoption in 2016 provide the necessary control strategy to bring the entire Valley into attainment of the 24

- hour standard by 2018, and the annual standard by 2020

.

Tables 5 and 6 list the Valley

- wide emissions levels used in the annual and 24

- hour PM2.5 attainment demonstrations, respectively. Baseline emissi on levels reflect the implementation of adopted ARB and District control measures. Three additional District rules that were adopted subsequent to the preparation of the baseline inventory plus one new commitment provide the remaining emissions reductions needed to reach the attainment targets.

a. Impact of preliminary 2014 PM2.5 data

The drought

- related meteorological conditions that affected PM2.5 concentrations in the San Joaquin Valley during 2013 continued into 2014. Although complete data for 2014 is not yet available, this section provides a preliminary assessment of 2014 air qu ality data in relation to the attainment demonstration.

Despite the ongoing persistence of the drought, air quality conditions in 2014 generally improved at most locations, particularly in the northern and central portions of the Valley. This is an ind ication that although drought conditions are continuing, progress is resuming as a result of ongoing emission reductions. However, because 2014 design values will reflect the impact of multiple years of drought, a comparison to the 2013 design values used in the attainment demonstration is expected to be mixed, with some locations recording design values that are slightly lower, and other locations recording design values that are slightly higher. Based on an assessment of the PM2.5 levels predicted for 2 020 as well as ongoing trends and analyses, consideration of 2014 design values is expected to remain consistent with the current attainment demonstration. However, ARB and the District will continue to monitor the impacts of the drought and its relations hip to future PM2.5 attainment needs.

- 6812. SUMMARY

Consideration of the entirety of information presented in the weight of evidence provides a consistent assessment that supports the modeled attainment date of 2018 for the 24

- hour PM2.5 standard and 2020 for the annual PM2.5 sta n d ard . The substantial continuing reductions that will result from implementation of the ongoing co ntrol program, coupled with measures addressing residential wood burning and cooking, are consistent with the results predicted in the modeled attainment demonstration. This weight of evidence assessment is based upon the following factors:

• Over the last 12 years progress has occurred in reducing annual PM2 .5 concentrations. The annual desig n value has decreased by over 30 to 35 percent.

• The 24

- hour design value has decreased by 30 to 45 percent, while the number of exceedances has decreased by 60 to 80 percent.

• The attainment demonstration accounts for drought related meteorological conditions that caused the 2013 annual an d 2 4

- hour PM2.5 design values to be higher than in previous years.

• Both receptor and photochemical grid based modeling have identified residential wood burning as a significant contributor to wintertime PM2.5 concentrations. The reductions in the carbon aceous component of PM2.5 that have occurred can be linked to implementation of the District’s residential wood burning curtailment program.

• Evaluation of emissions inventory data , monitoring studies, and photochemical modeling indicate that controlling NOx emissions is the most effective strategy to reduce ammonium nitrate concentrations.

• E valuation of monitoring studies and photochemical modeling indicate s that controlling VOCs is not an effective strategy to reduce nitrate concentrations

.

• The decrease in ammonium nitrate concentrations observed at Valley monitoring sites tracks concurrent reductions in NOx emissions as well as trends in gaseous NOx concentrations.

• S ubstantial NOx and PM2.5 emission reductions will occur between 2012 and 2020 due to the implementation of on

- going measures and additional new measures . As a result of these programs, NOx emi ssions will decrease by 38 percent, a nd PM2.5 emissions by nearly eight percent.

• The modeled attainment demonstration pred ict s that all sites in the Valley will attain the annual standard by 2020

. This modeling assessment is consistent with the

A

- 69benefits seen from previous reductions in the sources and pollutants being addressed as part of the attainment strategy.

• The attainmen t d emonstration shows that in 2018 the 24

- hour PM2.5 standard will be attained

### SAN JOAQUIN VALLEY P M2.5 WEIGHT OF EVIDE NCE ANALYSIS

APPENDIX A 2

ASSESSMENT OF THE RE PRESENTATIVENESS OF

2011 PM2.5 BETA ATTE NUATION MONITOR DATA FROM MADERAAssessment of the Representativeness of 2011 PM2.5 Beta Attenuation Monitor Data from Madera

Overview

PM 2.5 monitoring in Madera began in 2010 with deployment of the Federal Equivalence Method Beta Attenuation Monitor (FEM BAM) at the San Joaquin Valley Air Pollution Control District (SJVAPCD) Madera City monitoring site. Since there was no previous PM2.5 d ata record for Madera, there was no baseline for evaluating the PM2.5 levels measured with the BAM. Based on established concentration gradients within the San Joaquin Valley, concentrations measured in Madera are expected to be similar or slightly higher than measurements in Merced, but lower than those from Fresno. They should also depict a strong seasonal pattern, with low season average concentrations below 10 μ g/m 3 . However, the first complete data year, 2011, did not conform with these expectations

. Comparison of 2011 concentrations measured at Madera and Fresno revealed that on an annual basis, Madera was 30 percent higher compared with measurements in Fresno, or 4.8 μ g/m 3 . During what is typically regarded as the low PM season, measured concent rations at Madera were twice as high as those measured in Fresno.

As SJVAPCD monitoring staff continued to perform required operational checks on the BAM, the measurement differences between the two sites decreased. However, it was not until 2014 when a dditional technical adjustments consistent with BAM operational protocols were made, and parallel Federal Reference Method (FRM) monitoring was conducted for verification of measured levels, that measured concentrations from the BAM began to reflect the sp atial and temporal variation characteristic of the Valley.

The analysis presented below indicates that 2011 data collected at Madera were not representative of air quality in the area. Nevertheless, use of these data in the attainment demonstration, cou pled with data presented in the weight of evidence document, shows attainment of the 15 μ g/m 3 annual PM2.5 standard by 2020.

PM2.5 FEM BAMs in the Monitoring Network

The BAM instruments play an important role in California’s monitoring program because th ey collect continuous data and they are less resource intensive to operate. In many applications throughout the State, the BAM measurements have been found to be higher than FRM monitors run in parallel, especially when low concentrations are anticipated. Recognizing the potential issues with comparability of PM2.5 BAM data to filter

- based FRM monitor data, U.S. EPA provided flexibility in how these data are used in determining compliance with National Ambient Air Quality Standards (NAAQS). The U.S. EPA enables each agency to specify if they intend to use data from PM2.5 FEM

A2

- 1BAMs for comparison to the NAAQS. U.S. EPA has previously approved requests to exclude FEM BAMs for use in establishing compliance with the NAAQS in both, the South Coast and San Die go. However, this type of request requires parallel FRM/FEM monitoring, which was not available at Madera in 2011.

Comparison of PM2.5 FEM BAM at Madera and PM2.5 FRM at Fresno for 2011

Figure 1 shows the location of PM2.5 monitors in the San Joaquin Valley. Multiple years of PM2.5 data indicate that concentrations have a distinct spatial pattern, increasing from the northern portion to the southern portion of the Valley. Figure 2 illustrates trends in the design value for the three regions in the Va lley. The two central Valley monitoring sites with FEM BAMs, Clovis and Madera, are not included in Figure 2, since readings from these two sites altered previously established FRM

- based concentration gradients. Since 2005, the basin design value came fr om sites in the southern portion of the Valley. Based on this established spatial gradient, we expect concentrations at Madera to be higher than at Merced, but lower than at Fresno. In 2013 Madera had the highest annual design value in the basin.

Figure 1. San Joaquin Valley PM2.5 Monitoring Locations

A2

- 2Comparison of 2011 Madera BAM data and Fresno FRM data revealed that PM2.5 concentrations at Madera were significantly higher compared to the FRM at Fresno. Table 1 and Figure 3 compare the data for tw o sites. Concentrations at the two sites correlated well, with a correlation coefficient of 0.94. This correlation suggests that the concentrations at both sites are driven by regional meteorological phenomena. However, the 2011 Madera and Fresno averag es, based on matching data, were 20.9 μ g/m 3 and 16.1 μ g/m 3 , respectively. During the low season the difference was further magnified, with Madera concentrations on average twice the level of Fresno. The very high intercept of more than 9.4 μ g/m 3 sugges ts a bias in the FEM BAM reading at Madera.

- 3Low Season BAM Data Significantly Impacted by Sampling Artifacts

PM2.5 concentrations in the Valley exhibit a pronounced seasonal pattern with high concentrations during winter and low concentrations the rest of the year. During the 2011 low season, PM2.5 concentrations at Madera were significantly higher than the
rest of the sites in the Valley. As illustrated in Figure 4 and Table 2, the Madera BAM concentrations were twice the level of the closest FRM, located in Fresno. y = 0.7108x + 9.4194 R2 = 0.8869

The BAM sampling artifact at the Madera site is further illustrated by the number of days with low PM2.5 concentrations. Typically, half of the samples annually have concentrations less than 10 μ g/m 3 . In 2011, as shown in Table 3, over half of the sample s collected at Fresno were below 10 μ g/m 3 , but only 7 percent of samples at Madera were below that level.

- 5Zero A djustment Impact on BAM Readings at Madera

A n annu al background zero test is conducted on PM2.5 FEM BAMs to establish the value of any adjustment that may be needed due to a bias in mea surement, including beta

- source fluctuations, mechanically induced bias, and site

- specific interf erences such as radio frequencies or other electromagnetic perturbations. T he zero adjustment test on the FEM monitor at Madera was initially conducted using internal air. In April of 2014, the instrument was, for the first time, adju sted using external air. Following this adjustment, low season concentrations shifted downward compared to the previous years (Figure 8) and are more consistent with other monitors in the Valley (Figure 9).

- 7Parallel FRM Monitoring at Madera

To further understand the data collected at Madera, in July of 2014, an FRM sampler was deployed to run in parallel with the BAM at the Madera site. These parallel data show that after the shift in concentrations in late April/early May, the BAM monitor is now reporting concentrations consistent with the FRM. The parallel FRM/BAM data for July through September 2014 indicates the BAM is running about 7 percent or
0.6 μ g/m 3 higher. The average BAM concentrations for July through September were
8.9 μ g/m 3 , which is about 50 percent lower compared to what Madera meas ured in previous years (Figure 12) and is more consistent with what other sites are measuring during these three months (Figure 13). 0 2 4 6 8 10 12 14 16 18 20

- 8Conclusion s
2011 PM2.5 FEM BAM data at Madera appear to be biased high due to sampling artifacts. While these data ar e not representative of air quality in the central portion of the Valley, staff has nevertheless included them in the attainment demonstration. In 2014 a PM2.5 FRM was deployed at Madera to run in parallel with the FEM BAM to help verify measured concentr ations. It is expected that this parallel monitoring, along with the proper sampler maintenance and operation, will lead to future design values that are representative of air quality in the region.

PM2.5 SOURCE APPORTI ONMENT FOR THE SAN JOAQUIN VALL EY AIR BASIN USING THE CHEMICAL MASS BA LANCE RECEPTOR MODELPM2.5 Source Apportionment for the San Joaquin Valley Air Basin Using the Chemical Mass Balance Receptor M odel

1) Data Collection and Screening PM2.5 chemical composition data collected at the Bakersfield

- California and Fresno

- 1 st Street sites were used for the Chemical Mass Balance (CMB) analysis. The two sites are part of the Chemical Speciation Network (CSN) and use the SASS (Spiral Aerosol Speciation Sampler, Met One, Grants Pass, OR.) for data collection. The Bakersfield

- California and Fresno

- 1st samplers are configured with several channels, each channel containing one 47m mfilter with a 6.7 L/min flow rate. One channel contains a Whatman Teflon®

- membrane filter for mass by gravimetry and elements by XRF. Another channel includes a magnesium oxide

- coated aluminum (Al) honeycomb after the cyclone followed by a Nylasorb nylo n

- membrane filter for water

- soluble anions i.e., NO 3 − and SO 4 = ) and cations (i.e., ammonium [NH 4 + ] and water

- soluble sodium [Na + ] and potassium [K + ]) by IC. In the past, another channel containing a Whatman QMA quartz

- fiber filter was used for OC and EC a nalysis by the STN thermal/optical transmittance (TOT) protocol. In recent years changes were made to the carbon sampling and analysis method. The collection method changed from the MetOne SASS to the URG3000N sampler, which is very similar to the IMPROVE module C sampler. The analytical method was changed from the NIOSH

- like thermal optical transmittance (TOT) method to IMPROVE_A thermal optical reflectance (TOR). A new backup quartz fil ter is also collected using the URG3000N to help assess artifacts. The backup filter is placed behind the routine quartz sampler filter. This change took place on May 3, 2007 at Bakersfield and April 1, 2009 at Fresno.

Due to the change in carbon colle ction and analysis method, several data sets were generated for CMB modeling to allow separate analysis of old and new carbon data. Throughout this document we will refer to ‘old carbon’ data and ‘new carbon’ data. Old carbon data were collected using th e SASS sampler and analyzed using the NIOSH

- like thermal optical transmittance (TOT) method. New carbon data were collected using the modified IMPROVE version II Module C sampler, the URG3000N, and analyzed using the IMPROVE

- A thermal optical reflectance (TOR) method. Both old and new carbon data were corrected for sampling artifacts prior to running CMB.

A3

- 12) Data Preparation Organic carbon (OC) data were corrected for sampling artifacts prior to running CMB. Old carbon data, collected using the SASS samp ler and analyzed using the NIOSH

- like thermal optical transmittance (TOT) method, were corrected by subtracting a California network

- wide average organic carbon blank of 1 ug/m3 from the measured OC concentration. New carbon data were adjusted by subtract ing network

- wide monthly average concentrations measured on a backup filter from daily measurements of organic carbon [88370]. The monthly average backup concentrations are shown in Table 1.

3) Source Profiles The major source types which have been found to contribute to primary PM2.5 in the San Joaquin Valley are motor vehicle exhaust, vegetative burning, geological material, marine

- derived aerosols, residual or crude oil combustion, and tire and brake wear. Most of the source profiles applicable to the San Joaquin Valley were determined during the California Regional PM10/PM2.5 Air Quality Study (CRPAQS) or earlier. Therefore, the profiles used in this analysis, listed in Table 4, are the same profiles that were used in the previous analysis for the 2008 San Joaquin Valley PM2.5 Plan.

Motor vehicle profiles for diesel (DIES) and gasoline (GAS) (Fujita et al., 2005) were used in modeling PM2.5 concentrations. Since more specific organic markers for gasoline and diesel were not available at the receptor site, the two profiles were collinear and had to be combined into a single profile representing motor vehicle emissions. Diesel and gasoline vehicle emissions source profiles were combined in proportions equivalent to their county

- level contributions to the PM2.5 emissions to produce a single emission

- weighted overall so urce profile. Table 2 lists PM2.5 emissions (EMFAC 2011, July 2011) that were used as a basis for creating county

- based composite profiles for Bakersfield and Fresno.

- 4Biomass burning was represented using an agricultural burning profile (AgBWheat) from June through October and a composite res idential wood burning profile (WBOakEuc) the rest of the year. The agricultural burning profile (AgBWheat) was based on burning of wheat stubble (Fitz et al., 2000). The residential wood burning profile (WBOakEuc) was used to represent residential wood c ombustion during colder months and was calculated as an average of oak and eucalyptus.

Geological material in the San Joaquin Valley comes from a variety of sources, including roads (paved and unpaved), agricultural operations such as land preparation

an d harvesting, construction, and soil erosion. The Central California Fugitive Dust Characterization Study acquired 47 samples from 37 areas (Chow et al., 2003). These included: 1) paved road dust from urban and rural areas, 2) unpaved road dust, 3) agric ultural soil from five crop fields (almond, cotton, grape, safflower, and tomato), 4) dairy and feedlot soil, 5) salt buildup deposits from irrigation canal drainages, and 6) building construction/earthmoving soil.

In addition to these latest profiles, s ome older soil profiles collected in the Valley in the late 80's were also used to create composite profiles that best represent fugitive dust sources at each site in the San Joaquin Valley. Information on the relative fractions of paved and unpaved road dust, as well as agricultural dust, along with information on the seasonality of agricultural operations and predominant crop types were used to determine which source profiles to include in each composite. Site specific composite profiles were then used in the CMB analysis. Table 3 lists geological profiles included in the composites created for modeling PM2.5 concentrations. Appendix A includes additional information about geological profiles.

- 5Sea salt was represented using a reacted sea salt profile, MARINE75, in which 25 percent of the Cl was replaced by nitrate on a molar basis (Chow et al., 1996a).

Tire and brake samples were collected as part of the ‘Development of a Gas and Particulate Matter Organic Speciation Profile Database’ conducted by CE

- CERT (Fitz et

a l., 2000). Tire and brake samples were composited into a single weighted average profile. The two profiles were weighted based on EMFAC 2011 emissions, which estimate a 9 to 1 ratio of brake emissions to tire emissions.

Secondary nitrate and sulfate were represented by pure ammonium nitrate (NH 4 NO 3 ) and ammonium sulfate (NH 4 ) 2 SO 4 . A “pure” OC profile was used to represent other unidentified primary sources, contributions from secondary OC, and the possible positive OC sampling artifacts.

Crude

- oil comb ustion profiles were included to help explain ambient concentrations of vanadium (V) and nickel (Ni). The profile representing the Santa Fe crude

- oil broiler at the Westside Kern County oil field helped to explain vanadium and nickel concentrations at Bak ersfield, while the crude

- oil profile representing the Chevron Racetrack boiler at the Kern River oil field provided a better fit at Fresno.

- 6Data for each sampling day were run individually under several scenarios. E ach run included the following profiles: ammonium nitrate, ammonium sulfate, motor vehicle, fugitive dust, tire and brake wear, marine, and in the case of Bakersfield, crude oil combustion. In the case of Fresno, the crude oil combustion profile was inclu ded only when it was necessary to explain the vanadium and nickel contributions. Biomass burning and ‘other OC’ profiles were included as needed. First, all data were run with a biomass burning profile (AgBWheat from June through October, WBoakEuc the re st of the year) and the ‘other OC’. The results were examined to determine if all source contributions were positive and performance parameters were within acceptable ranges. If using the biomass burning profile along with the ‘other OC’ gave unsatisfact ory results, the data were run again using just one of the two profiles, as described below.

1. Run 1 included a biomass burning profile and ‘other OC’.
2. Run 2 included a biomass burning profile but not the ‘other OC’ profile. It was geared towards days when primary sources of organic carbon (biomass burning, motor vehicle exhaust, and geological material) sufficiently accounted for the ambient organic carbon. 3. Run 3 included ‘other OC’ but no biomass burning profile. It was geared towards days with no bioma ss burning and applied only when soluble potassium concentration was reported as zero. Data from several runs were combined into a single data file to best represent source contributions. Data were combined as follows:

1. Days with estimated positive contributions from wood burning and ‘other OC’ were included in the composite file.
2. Days with estimated negative contributions from ‘Other OC’ were treated as follows:

a. If there should have been no burning on that day because the soluble potassium concentra tion was zero, run 3 which includes the ‘other OC’ and no wood burning was utilized. b. If there could have been wood burning because the soluble potassium concentration was greater than zero, run 2 which includes biomass burning was used. 3. Occasionally, the r esults were still unsatisfactory and profiles were adjusted individually for a particular day. Composite files were used for subsequent analysis. Table 7 shows the number of data points from each run included in the composite file.

6) Comparison of CMB Estimates using Old and New Carbon The Bakersfield

- California site has 14 days with parallel old and new carbon data. Since these data were collected during the low season, the average PM2.5

c oncentration was only 13.6 ug/m3. The CMB model was applied to the old and new carbon data to evaluate the impact of changing carbon collection and analysis on source contribution. Using the old carbon, 10 percent more of the mass was apportioned to sour ces. Regardless of what carbon data were used, the model apportioned almost the same concentration to each source, except ‘other OC’. Using the old carbon data, on average, 2.5 ug/m3 was assigned to the ‘other OC’. Switching to the new carbon data reduc ed the ‘other OC’ estimate to 1 ug/m3. There were also several days when the motor vehicle contribution estimate differed slightly depending on which carbon data were used. Even though, on average there is no difference in measured EC between the old and new carbon method, on these particular days the measurements differed and that difference was reflected in the motor vehicle contribution. The new OC measurement is, on average, about 50 percent lower compared to the old one. This impacts how much mass gets apportioned to the ‘other OC’ but has no impact on motor vehicle or biomass burning contributions. Figures 3 through 6 compare percent of mass and contribution from major carbon sources using old and new carbon data.

- 87) Results The CMB model wa s applied to 424 samples at BAC (157 with old carbon and 267 with new carbon) and 590 samples at FSF (390 with old carbon and 200 with new). Source contribution estimates were averaged to determine a typical contribution. Separately, days with concentrat ions greater than 30 ug/m3 were averaged to determine the typical contribution on a high PM2.5 day.

Performance measures and statistics used to evaluate the validity of CMB source apportionments include chi

- square, r

- square, and percent of mass accounted for by the estimated source contributions. The target values for these performance measures are chi

- square less than 4, r

- square greater than 0.8, and percent of mass accounted for by the estimated source contributions between 80% and 120%. The average performance measures for both sites were within the acceptable limits as shown in Tables 8 and 10. 0 20 40 60 80 100 120 1405/3/075/6/075/12/075/15/076/2/076/5/076/11/076/14/076/17/076/20/076/23/076/26/076/29/077/5/07Percent Figure 3.

- 9The results are discussed separately for each site for two reasons. First of all, each site switched to the new method at a different time. Second of all, 2009 had to be excluded from the annual average calculation at Bakersfield due to missing data.

a) Bakersfield (BAC) The average PM2.5 concentration based on old carbon data for 2006 was 20.5 ug/m3. Based on the new carbon data, the 2008 and 2010 average P M2.5 concentration was 18.6 ug/m3. Between 2006 and 2007 (old carbon data) there were 29 high days with chemical composition data. The average PM2.5 concentration on these days was 47 ug/m3,. Between 2007 and 2010 (new carbon data), there were 36 high days with chemical composition data, with the average PM2.5 concentration of 46.7 ug/m3. Sources identified by the CMB accounted for 79 to 94 percent on annual basis and 94 to 95 percent on high days.

i) Annual Ammonium nitrate dominated the PM2.5 mas s contributing 42 to 47 percent of mass. Ammonium sulfate and biomass burning were the next most important sources contributing 10 to 12 percent of mass. Biomass burning contributed 9 to 10 to percent of the mass. The ‘Other OC’ contribution depended on the carbon data method; using old carbon apportioned 16 percent of mass to the ‘other OC’ while using new carbon reduced that contribution to 8 percent. Geological material comprised 7 to 10 percent of the mass. Each of the remaining sources (tire and b rake wear, sea salt, and oil combustion) contributed no more than 1 percent of the mass.

ii) High Days The ammonium nitrate contribution was even more significant on high days, ranging from 59 to 67 percent. Biomass burning and motor vehicles each contributed
9 to 13 percent. The ‘Other OC’ contribution ranged from 3 percent using new carbon
to 10 percent using old carbon. Geological material contributed about 2 percent. Each of the remaining sources, tire and brake wear, sea salt, and oil combustion contri buted less than 1 percent of the mass.

A3

- 10b) Fresno (FSF) The average PM2.5 concentration based on old carbon data for 2006 to 2008 was 20.3 ug/m3. Based on the new carbon data, the 2010 average PM2.5 concentration was 14.2 ug/m3. Between 2006 and 2009 (ol d carbon data) there were 67 high days with chemical composition data. The average PM2.5 concentration on these days was 46.3 ug/m3. Between 2009 and 2010 (new carbon data), there were 22 high days with chemical composition data, with the average concent ration of 40.6 ug/m3. Sources identified by the CMB accounted for 74 to 97 percent of the mass on an annual basis and 82 to 93 percent on high days.

i) Annual Ammonium nitrate dominated the PM2.5 mass contributing 40 to 43 percent of the mass. Biomass b urning contributed about 16 percent of the mass. Motor vehicles contributed slightly less, 11 to 13 percent. The ammonium sulfate contribution was 9 to 11 percent. The ‘Other OC’ contribution, once again, depended on carbon data; using old carbon apport ioned 18 percent of mass to the ‘other OC’ while using new carbon reduced that contribution to 9 percent. Geological material comprised 4 to 6 percent of the mass. Each of the remaining sources contributed no more than 1 percent of the mass.

ii) High Days Th e ammonium nitrate contribution was even more significant on high days when 52 to 54 percent of the mass was ammonium nitrate. Biomass burning was the second most significant source, contributing 19 to 23 percent. The motor vehicle contribution ranged fr om 9 to 12 percent. The ‘Other OC’ ranged from 4 percent using new carbon data to 13 percent using old carbon data. The remaining sources contributed less than
1 percent of the mass.

### Source Apportionment of PM 2.5 

### Measured at the Fresno and Bakersfield Chemical Speciation Network Sites in San Joaquin Valley Using the Positive Matrix Factorization Model

Sample Collection and Data Screening

PM 2.5 chemical speciation samples were collected on a one

- in

- three day schedule at the Fresno

- First St. and Bakersfield

- California Ave. Chemical Speciation Network (CSN) monitoring sites located in the San Joaquin Valley (SJV). There were good a greements between PM 2.5 data collected by the speciation samplers and the collocated Federal Reference Method (FRM) samplers in matched Fresno data ( 340 samples, slope = 1.00, Intercept = 1.08, r 2 = 0.97) and Bakersfield ( 175 samples, slope = 0.94, Intercept = 0.92, r 2 = 0.94) between 2008 and 2010. The Thermal Optical Transmittance (TOT) protocol had been used to analyze carbon mass collected on the quartz filters. This method was changed to the Thermal Optical Reflectance (TOR) protocol a nd TOR organic carbon (OC) and elemental carbon (EC) concentrations were available starting from January 2008 and April 2009 at the Bakersfield and Fresno monitoring sites, respectively. Only the speciation data for which TOR OC and EC concentrations were available were considered in this source apportionment study. Since a carbon denuder that minimizes the positive sampling artifact caused by adsorption of gaseous organic materials was not included upstream of quartz filter in the CSN samplers, and none o f the reported CSN data were blank corrected, an integrated OC artifact concentration that includes OC adsorption and desorption was estimated utilizing the intercept of the regression of OC concentrations against PM 2.5 mass concentrations (Tolocka et al. 2001, Kim et al. 2005). Samples for which PM 2.5 or OC concentrations had an error flag and samples for which the PM 2.5 or OC data were not available were excluded from the regression analysis between PM 2.5 and OC concentrations. Comparing co

- located PM 2. 5 data measured by CSN and FRM samplers, and comparing PM 2.5 and Sulfur (S) concentrations, outliers were censored for the two data sets. Using 189 data points out of 353 data points between 2009 and 2010 at Fresno and 187 data points out of 192 data poin ts at Bakersfield between 2008 and 2010, the intercept s of 0.576 μg/m 3 and 1.480 μg/m 3 in PM 2.5 regression against OC concentrations are considered to be the integrated OC artifact concentrations at Fresno and Bakersfield, respectively (Figure 1). The OC concentrations analyzed in this study were corrected by subtracting the integrated OC artifact concentrations.

- 2The Posit ive matrix factorization model version 2 (PMF2) model was used for the source apportionment of PM 2.5 at the Fresno and Bakersfield monitoring sites. Samples were excluded from the data set for which the PM 2.5 , artifact corrected OC, or EC data were not av ailable or below zero, or for which PM 2.5 artifact corrected OC, or EC had an error flag. Samples for which the sum of all measured species were larger than twice the PM 2.5 concentrations or the sum of all measured species were less than 50% of PM 2.5 concentrations were also excluded. Finally, samples that contain fireworks particles collected on Independence Day and New Year’s Day were excluded since they had unusually high concentrations of OC, EC, K + , Na + and metals. Overall, 10.3% of the Fresno data and 16.5% of the Bakersfield data were excluded in this study. For the chemical species screening, X

- Ray Fluorescence (XRF) S was excluded from the analyses to prevent double counting of mass concentrations. Due to the higher analytical precision com pared to XRF Na and XRF K, IC Na + and IC K + were included in the analyses. Chemical species below MDL values more than 90% were excluded. As recommended by Paatero and Hopke (2003), the species that had a Signal

- to

- Noise ( S/N ) ratio below 0.2 were exclud ed. Thus, a total of 174 samples and 21 species including PM 2.5 mass concentrations collected between April 2009 and December 2010 were used for the Fresno site. For the Bakersfield site, a total of 147 samples and 24 species including PM 2.5 mass concent rations collected between January 2008 and December 2010 were used. Since new TOR OC and EC concentrations were not accompanied by detection limit and uncertainty values, a comprehensive set of uncertainty structure (i.e., 7% of measured concentration) es timated by Kim et al. (2005) and 0.1 μg/m 3 of detection limit value estimated from the State and Local Air Monitoring Stations (SLAM) speciation data were used in this study. Summaries of PM 2.5 speciation data are provided in Tables A1 and A2 in the Appen dix. The procedure of Polissar et al. (1998) was used to assign input data for PMF2. The measurement values are used for the input concentration data, and the sum of the analytical uncertainty and one

- third of the detection limit value is used as the input uncertainty data assigned to each measured value. Concentration values below the detection limit are replaced by half of the detection limit values, and their input uncertainties are set at five

- sixth of the detection limit values. Missing values are replaced by the geometric mean of the measured values for each species. To down

weight these replaced data and then to reduce their influence on the solution, their accompanying uncertainties are set at four times the geometric mean value. The conditional probability function (CPF) an alysis was used to estimate the possible directions of the local source impacts (Kim and Hopke, 2004). The CPF was calculated for each source using the PMF2 source contributions coupled with wind data. As recommended by Paatero and Hopke (2003), which is to down

- weight the variable in the analysis so that the noise does not compromise the solution, it was found necessary to increase the input uncertainties of OC, EC, and Cl by a factor of 3 for the Fresno data and OC and Na + by a factor of 3 for the Baker sfield data to obtain physically interpretable PMF2 results. A4

- 3PMF Results Seven major sources were resolved from PMF2 analyses for both sites (matrix rotational parameter: Fresno FPEAK = 0.1; Bakersfield FPEAK = 0). The comparison of the reconstructed PM 2. 5 contributions (sum of contributions from all sources) with measured PM 2.5 concentrations shown in Figure 2 indicates that the resolved sources effectively reproduce the measured values and account for most of the variation in the PM 2.5 concentrations ( sl ope = 0.88, r 2 = 0.95 for Fresno data; slope = 0.93, r 2 = 0.91 for Bakersfield data).

**Average Source Contributions** As shown in Figure 3 and Table A3 which present average source contributions, secondary nitrate contributed the most at both sites (35% at the Fresno site, 41% at the Bakersfield site). The pie charts indicate that three major sources (i.e., secondary nitrate, secondary sulfate, and motor vehicle) contributed 74% of PM 2.5 concentrations at both sites. Figure 4 shows monthly average source c ontributions. Secondary nitrate, motor vehicle, and biomass smoke contributed the most in winter. The source profiles, corresponding source contributions, weekday/weekend variations, monthly averaged source contributions, and potential source directions are presented in Figures A1 through A10 in the Appendix. The secondary nitrate factor was identified by its high concentration of NO 3 - and NH 4 +

. It consisted of NH 4 NO 3 and several minor species such as secondary OC and EC that transport together. It cont ributed the most at both sites, accounting for 35% and 41% of the PM 2.5 mass concentrations at Fresno and Bakersfield, respectively. Bakersfield showed higher secondary nitrate concentrations than Fresno. Secondary nitrate particles had winter

- high tren ds at both sites. Secondary sulfate was identified by its high concentration of SO 4 2

- and NH 4 + and accounted for 27% and 20% of the PM 2.5 mass concentration at Fresno and Bakersfield, respectively. Secondary nitrate and secondary sulfate did not show cle ar weekday/weekend variations. Secondary sulfate showed seasonal variations with higher concentrations in summer when the photochemical activity was highest at both sites. The CPF plots for secondary nitrate pointed S and NE at both sites. The CPF plots for secondary sulfate pointed SE at the Fresno site and SW at the Bakersfield site. The motor vehicle factor was identified by its high concentration of OC, EC, NO 3 - , and minor species such as Fe (Watson et al., 1994). Motor vehicle emissions contributed 12% and 13% of the PM 2.5 mass concentrations at Fresno and Bakersfield, respectively. Motor vehicle emissions did not show clear weekday/weekend variations at either site, however there was a winter

- high seasonal trend.

A4

- 4The biomass smoke factor was ch aracterized by OC, EC, and K + (Watson et al., 2001) and contributed 11% and 10% to the PM 2.5 mass concentrations at Fresno and Bakersfield, respectively. The biomass smoke category reflects contributions from residential wood burning and smoke from commer cial cooking. The biomass smoke did not show weekday/weekend variations. The biomass smoke did show winter

- high trends suggesting that it was mostly contributed by residential wood burning. The CPF plots for the biomass smoke pointed to high contribution s from NE and S at both sites.

- 7The airborne soil factor was identified by its high concentrations of Si, Al, Ca and Fe. It contributed 7% and 10% to the PM 2.5 mass concentration at Fresno and Bakersfield, respect ively. Airborne soil reflects wind

- blown dust as well as re

- suspended crustal materials by road traffic as indicated by the presence of OC or EC in the source profiles. Airborne soil did not show clear weekday/weekend variation. Both sites exhibited aut umn

- high seasonal trends. The CPF plots for airborne soil suggested high contributions from SW and S at both sites. The aged sea salt factor was represented by its high concentrations of NO 3 - , SO 4 2

- , and Na + , accounting for 6% the PM 2.5 mass concentration at Fresno and 4% at Bakersfield. Aged sea salt reflects particles in which Cl - in the fresh sea salt is partially displaced by acidic gases during the transport and collected along with NO 3 - and SO 4 2

- (Song and Carmichael, 1999). Aged sea salt did not s how weekday/weekend variation at either site. Aged sea salt had high contributions in summer at the Fresno site. Interestingly, it had a high contribution in winter at the Bakersfield site. The CPF plot for aged sea salt at Fresno site pointed towards N E. The CPF plot for aged sea salt at Bakersfield site suggested high contributions from NE and S. A possible industrial source such as metal processing that was characterized by OC, EC, Fe, and Zn was identified at both sites. This source accounted for 2 % of the PM 2.5 mass concentrations at both sites. It showed weak weekday

- high variations at the Bakersfield site. The i ndustrial source showed winter

- high variations at the Fresno site. The CPF plot suggested high contributions from NE and SW at both si tes.

- Feb.) are shown in Figure 5 for percentiles and in Table A4 for mass concentrations. The contributions from secondary nitrate and motor vehicle were increas ed from 35% up to 54% and from 12% up to 23%, respectively, at the Fresno site. The biomass burning contributions also increased slightly from 11% up to 13% at Fresno site. At the Bakersfield site, the contributions from secondary nitrate increased from 41% up to 64% and aged sea salt from 4% up to 6%.

Conclusions

PM 2.5 speciation and related meteorological data collected at the Fresno

- First St. and Bakersfield

- California Ave. CSN monitoring sites between 2008 and 2010 were analyzed by PMF2. Seven major PM 2.5 sources were identified at both monitoring sites: secondary nitrate, secondary sulfate, motor vehicle, biomass smoke, airborne soil, aged sea salt, and industrial. Annual average and high day source contributions showed that secondary nitrate, seco ndary sulfate, motor vehicles, and biomass burning were the largest contributors to PM 2.5 concentrations.

Additional Emission Reductions Achieved Towards Meeting Aggregate Commitment

A. State

- funded Incentive

- based Emission Reduction Measures

. At its board hearing in October 2014, ARB approved the Report on Reductions Achieved from Incentive

- Based Emission Reduction Measures in the San Joaquin Valley as the mechanism to allow California to receive SIP credit for specific reductions achieved through the Prop osition 1B and Moye r incentive programs. These incentives provide additiona l reductions of 7.8 tons per day (tpd) of NOx and 0.2 tpd of PM2.5 in 2014 and are being credited toward the State’s aggregate commitment

. This report was submitted to U.S. EPA on November 17, 2014. Information regarding this ARB Board item is available at http://www.arb.ca.gov/planning/sip/sjvpm25/sjvpm25.htm

.

B. Actual Com pliance with Truck and Bus Rule

.

ARB’s in

- use diesel fueled truck and bus regulation requires trucks and buses to install diesel particulate filters starting January 1 , 2012 and to upgrade to 2010 model year or newer engines starting January 1, 2015. W hen ARB adopted the rule staff’s emission reduction calculations were based on preliminary PM2.5 diesel particulate filter (DPF) efficiencies and assumed that owners of trucks with pre

- 2007 engines would retrofit those trucks rather than purchase new truck s. Based on current compliance reporting, staff have found that the DPFs are more efficient tha n original estimates and many owners of pre

- 2007 trucks opted to purchase new vehicles rather than retrofit. The original, 2008 SJV PM2.5 Plan baseline, baseli ne with rule, and net rule benefit emissions estimates are provided in Table B

- 1 below as annual average em ission estimates in tpd in 2014. These estimates utilized the latest draft version of EMFAC2011 that was available at the time.

Table B

- 1

.

SIP, Draft EMFAC2011 (Original Estimates Submitted to USEPA)
w/rule Baseline Benefit NOx PM2.5 Ex NOx PM2.5 Ex NOx PM2.5 Ex
110.6 1.97 111.8 3.69 1.19 1.73

For the original analysis of rule benefits in Table B

- 1 , staff assumed that the only compliance option that would be chosen by owners of trucks with pre

- 2007 engines to comply with the PM requirement of the rules would be to retrofit their trucks with aftermarket DPFs. However, since the time of the original analysis, based on reported data, staff have found that owners of trucks with pre

- 2007 engines selected a different compliance path. More owners than expected opted to turn

- over their older trucks and purchase newer ones

– which are cleaner than retrofits

-- rather than installing retrofit DPFs. Thus, the actual compliance paths that have been selected by truck owners

B

- 2have resulted in a cleaner than expected fleet and, therefore, addition al benefits beyond what was originally estimated.

To estimate the additional emission benefits caused by the higher than expected turn

over to newer, cleaner trucks, staff reviewed the latest available statewide data on the number of trucks with retrofits contained in ARB’s TRUCRS database, estimated the fraction of exp ected turn

- over to 2007 or 2010 engines for the remaining trucks, then re

ran EMFAC2011 to estimate the updated rule benefits.

Statewide, approximately 86,000 retrofits of California

- plated trucks in calendar year 2014 were assumed in the original EMFAC 2011 estimate. As of January 2014, 16,000 retrofits were reported in ARB’s TRUCRS database. For this analysis, the remaining trucks were assumed to be turned over to trucks having either 2007 or 2010 engines. Of the remaining 70,000 tru cks that are not r etrofitted, staff assume d that half (or 35,000) complied by turning over to trucks with 2007 standard engines while the other half turned over to trucks having 2010 standard engines. This 50/50 turn

- over assumption is conservative; and is supported by rep orting from truckers, who have indicated that purchase of a 2010 engine is a better business decision for trucks that will be kept long

- term

. This is supported by data that shows that there are a greater number of trucks with 2010

- 2013 engines available o n the market

, and trucks with 2010 or newer engines achieve better fuel economy.

The statewide turn

- over rates d etermined above are applied to the latest available truck populations. In th e San Joaquin Valley , data show 11,800 California plated T7 truck s, 5,000 T6 trucks, and 2,600 out

- of

- state T7 trucks. S ince T6 truc ks have smaller engines and emit less, staff assume d that the population of T6 trucks is equivalent to a 0.6 fraction of the T7 truck population (i.e. 40% are ‘all other buses’) consistent with EMFAC2011

. With these assumptions, the California plated “T7 equ ivalent” truck population in the San Joaquin Valley is estimated to be 14,800 trucks and the total (including both California and out

- of

- state) “T7 equivalent” population is 17,400 truc ks. T able B

- 2 below summarizes applying the statewide ratios to these Valley totals, which yields 6,023 California plated trucks an d 7,081 total trucks in the San Joaquin Valley for both the 2007 and 2010 standards.

C. 2012 PERP and Portable Engine ATCM

. The ARB Portable Equipment Registration Program (PERP) provides an important voluntary mechanism to allow owners and operators of portable engines and equipment to operate at various locations throug hout the State without obtaining individual operating permits in each local air district in which the unit may be operated. The Board originally approved the PERP Regulation in 1997. In 2004, ARB also established requirements for portable diesel

- fired en gines under the Airborne Toxic Control Measure for Diesel Particulate Matter from Portable Devices (Portable Engine ATCM) to ensure adequate control of air toxics emissions including diesel PM, for operation of such engines under PERP. The Portable Engine ATCM requires portable diesel

- fueled engines that have not been permitted or registered prior to January 1, 2006, to meet the most stringent of the federal or California emission standards for nonroad engines in effect at the time of re gistration or permit. These two programs reduce emissions by requiring the removal of uncertified engines from the registered fleet.

Amendments to both the Statewide PERP Regulation and Portable Engine ATCM were approved by the Board in 2010. The 2010 staff report for these amendments included the emission impact of both rules in 2010 and following years. The expected emission

B

- 4reductions realized by both rules were 25.2 tons per day of NOx and 1.9 tons per day of diesel PM statew ide beginning in 2011. The State submitted the PERP Regulation and Portable Engine ATCM in 2012. The 2008 PM2.5 Plan did not account for the emission reductions from these programs.

To reflect the portion of these emission reducti ons that occur in the Valley, staff apportioned the em ission reductions to reflect the portion of the Statewide equipment that operate in the San Joaquin Valley

. Due to the natural turnover of portable equipment and engines between 2011 and 2014, the emission reductions were scaled to refle ct 2014 emissions. Table B

- 5 provides the emission reductions from the PERP and Portable Diesel Engine ATCM that are being credited toward the State’s aggregate commitment. Information related to the emission reductions are documented in the 2010 staff r eport regarding these ARB programs and can be found at http://www.arb.ca.gov/portable/portable.htm and http://www.arb.ca.gov /regact/2010/perp2010/perpisor.pdf

B. Rule 9510 Indirect Source Review On

- Site Compliance

The District through its Rul e 9510, Indirect Source Review, requires construction and development projects to mitigate on

- site emission s or pay a fee to mitigate those projects. When U.S. EPA approved Rule 9510 (76 FR 26609), they did not credit

em ission reductions since U.S. EPA did not have information available at the time to determine which projects would comply with the rule through on

- site reductions as compared to projects that would elect to pay to achieve emission reductions off

- site

. The District now has a record of projects that have complied via the on

- sit e mitigation

. The documentation specifies the NOx and PM10 emission reductions for each pro ject. To further estimate the portion of PM2.5 applicable to the projects, staff applied a PM2.5 to PM10 emissions ratio of 0.15 and 0.92 to the PM10 totals for dust and exh aust,

B

- 6respectively

. T he District ’s list of projects (App endix B

- 2) documents that reductions of 0.1 tpd of PM2.5 reductions along with the 1.0 tpd of NOx reductions can be credited

.

C. Actu a l Compliance with Rule 4901

As part of the District’s PM2.5 Con tingency Quantification 2008 PM2.5 SIP , the District updated the emission reductions attributed to the Rule 4901 to meet 2015 contingency requirements . The emission reductions were higher than the previous estimate U.S. EPA noted in their September 20, 2011 Technical Support Document (TSD) . The previous estimates were based on 2006 air quality to estimate the number of days burning would have been curtailed prior to the rule being implemented . The District updated the emission reduction estimates based on 2009

- 2013 air quality data reflective of actual rule implementation . U.S. EPA app roved this approach and the associated contingency reductions in 2014 (79 FR 29327)

. This same methodology is being used to document the actual emission reductions that are appropriate for credit towards meeting the District’s aggregate commitment. The n ew estimate increase s the a m ount of PM2.5 reductions by 1.3 tpd beyond the 1.0 tpd reduction credited in the TSD.

D. Compliance with Rule 4320

In 2008, t he District adopted rule 4320. This rule requires that boilers, steam generators, or process heaters with a total rated heat input greater than 5 million BTU per hour comply with the new emission limits specified by the rule or pay an annual fee to the District. U.S. EPA approved Rule 4320 (76 FR 16696) in 2011 but di d not credit emission reductions as the compliance path sources would select was unknown at the time

. Now that rule 4320 has been fully implemented, the District has documentation demonstrating that operators of 472 of the applicable units chose to pay a fee and the operators of the remaining 692 units chose to retrofit to comply with the rule. Based on the emission limits and rule requirements , the District estimated the actual emission reductions for these 692 units as specified in Table B

- Based Emission Reduction Measure

On June 20, 2013, the District adopted Rule 9610: State Implementation Plan Credit for Emission Reductions Generated through Incentive Programs (Rule 9610). Rule 9610 provided an administrative mechanism for the District to receive credit towards State Implementation Plan requirements for emission reduct ions achieved in the San Joaquin Valley Air Basin through incentive programs ad ministered by the District, Natural Resource s Conservation Service (NRCS) , or ARB. Rule 9610 demonstrates how the reductions meet U.S. EPA requirements for credit toward fulfil ling the aggregate emission r eductions commitment in the 2008 PM2.5 Plan. Accor ding to Rule 9610 the D istrict provides an Annual Demonstration Report through a public process that lists specific project information including emission reductions from all t he incentive projects it administers. To date, the District has developed 2013 and 2014 Annual Demonstration reports that can be found at http://www.valleyair.org/MOP/mop9610_idx.htm

**Methodology**

Based on the woodstove replacement project list below , ARB followed U.S. EPA guidance to develop the methodology for the emission reduction credits. The formula for calculating the credits was based on U.S. EPA’s Guidance for Quantifying and Using Emission Reductions from Voluntary Woodstove Changeout Programs in State Implementation Plans prepared in 2006

. 1

The following general equation can be used to determine emissions of any source category 2 :

E = A x EF x ( 1

- ER/100) Where:

• E = emissions

• A = activity rate

• EF = emissions factor, and;

• ER = overall emission reduction efficiency, %

The basic equation above is modified since we are interested in the improvement in emissions based on the change in efficiency fro m old conventional stoves to newer more efficient stoves. Therefore, the equation becomes 3 :

E = A x EF x (NE conv /NE new ) Where:

• E = emissions

• A = activity rate

• EF = emissions factor, and;

• NE x = Net efficiency of the stove

The following generally explai ns and describes where the inputs are derived from.

Activity Rate

For residential wood combustion, the activity rate is expressed in tons of wood used per day and is provided as a single constant, and determined from the emissions inventory. For the activity rate, staff utilized ARB’s residential wood combustion documen tation that is used to estimate the criteria pollutant emissions from the various types of residential wood combustion for each county throughout the State. The activity rate from ARB’s documentation has a unit of measurement of tons per household and is provided below for each device type.

Emissions factors are reported in mass of pollutant per mass of dry wood, therefore cords needs to be converted into mass. Similar to the activity rate, staff utilized ARB’s residential wood combustion documentation that is used to estimate the criteria pollutant emissions from the various types of residential wood combustion for each county throughout the State. Because U.S. EPA’s gu idance does not include emissions estimates for fireplaces or other similar devices that burn natural gas, staff used emission factors from U.S. EPA’s AP42, 1.4: Natural Gas Combustion 7

.
Natural Gas Emission Factor
The emission factor for natural gas is given in lb/10 6 scf. 8 The following is the conversion to lbs/household based on activity rate for both fireplaces and woodstoves. (Results may differ due to rounding)
Scf/household conversion = (Btu/lbs of wood bur ned) 9 X (amount of lbs per ton) X (device activity rate) 10 ÷ (average gross heat value) 11

Open Hearth Fireplace

The following is the emission reduction credit, including referenced inputs from above, for replacing 2994 open hearth fireplaces with either certified wood, certified pellet, or gas devices.

Activity Rate

To calculate the activity rate, staff utilized ARB’s Residential Wood Combustion documentation. The average consumption of wood in the District is 0.50 tons per household.

Emission Factor

The emission factor for open hearth fireplaces using cord wood bundles for NOx and PM2.5 is 2.6 and 22.7 lb/ton fuel burned, respectively. 19

The emission factor for certified wood device using cord wood bundles for NOx and PM2.5 is 2 and 19.6 lb/ton fuel burned, respectively. 20 These emission factors represent the catalytic rather than the non

- catalytic mode of burning since the catalytic is more conservative within respect to PM2.5, but not NOx.

The emission factor for a certified pellet device using pellets for NOx and PM2.5 is 3.8 and 2.9 lb/ton fuel burned, respectively. 21 The same emission factors were use d for

non
