### Executive Summary

Introduction

The Air Resources Board’s proposed Stat e Strategy for California’s 2007 State Implementation Plan (SIP) is a comprehens ive strategy designed to attain federal air quality standards through a combination of technologically feasible, costeffective, and far reaching measures. It describes the scope of the State’s ozone and fine particulate matter (PM2.5) nona ttainment problems and presents ARB

staff’s recommendations on how California can comply with federal standards. The proposed strategy will be considered for adoption by ARB’s Governing Board on June 21-22, 2007.

Under State law, ARB has t he responsibility to develop SI P strategies for mobile sources and consumer products, to coordina te SIP strategies with the Bureau of Automotive Repair (BAR) and Department of Pesticide Regulation (DPR), and to oversee local district program s for stationary sources.

The 2007 SIP is the first plan designed to show how California will meet the

federal 8-hour ozone standard – it represents a transition from the less stringent

1-hour standard that was the benchmark fo r previous SIPs. Since the new standard is more stringent, the U.S. Envi ronmental Protection Agency (U.S. EPA) set presumptive deadlines that allow more time for attainment. Nonetheless, the measures California has adopted to m eet the 1-hour standard remain in place

and will deliver substantial new reductions over the next few years. These

measures have enabled San Diego, Ventura, Sant a Barbara, and the San Francisco Bay Area to meet t he 1-hour ozone standard.

The benefits of California’s mobile source control program are evident and serve

as the foundation for this new State Strate gy. For example, the mobile source regulations already in place will r educe today’s emissions from passenger vehicles and heavy-duty trucks another 50 percent by 2015. The ARB staff’s proposed State Strategy would further accelerate the reductions. Staff’s proposed State Strategy addresses three ke y mobile source issues: the need to clean up the legacy diesel fleets, the nat ional and international nature of many diesel fleets, and limitations on SIP credit for unsecured funding.

The proposed State Strategy, in combinat ion with local actions, would provide emission reductions necessary to the meet 8-hour ozone standard in the two most challenging regions -- the South Coast Air Basin and the San Joaquin Valley. The State Strategy is also necessary, in whole or part, for the Sacramento region, Ventura, and severa l locations downwind of urban areas.

Ozone SIPs are due to U.S. EPA in June 2007.

The State Strategy provides reducti ons needed for PM2.5 attainment in the South Coast and expected to be necessary for the San Joaquin Valley. PM2.5 SIPs for these two regions are due in 2008.April 26, 2007 2 Adoption of the St ate Strategy by the Boar d would create an enforceable commitment for new emission reductions by the attainment deadline for each region. These commitments reflect t he proposed attainment deadlines of 2024 for ozone for the South Coast and San Joaq uin Valley and a deadline of 2015 for PM2.5. As in past SIPs, staff has es timated the expected emission reductions

from various measures and a schedule fo r Board consideration. The Board retains the ability to modify staff propos als and achieve the necessary reductions through other measures or mechanisms.

This proposal includes aggregate emission reduction commitments for 2014 for South Coast and San Joaquin Valley PM2. 5, and for 2020 and 2023 for South Coast and San Joaquin Valley ozone. The commitments precede the attainment deadline by one year in order to comply wit h federal SIP require ments. Staff may propose additional commitments for Board consideration in the future to the extent necessary. A PM2. 5 SIP is under development by the San Joaquin Valley District and on track for adoption in 2008. The South Coast has proposed early adoption of a PM2.5 SIP in parallel wit h the ozone SIP due this year.

The 2023 commitment for ozone includes the long-term emission reductions

needed for ozone attainment in the Sout h Coast and San Joaquin Valley under the “new technology” provisions of t he Clean Air Act (section 182(e)(5)). Staff proposes that ARB take on the full legal commitment for these reductions with the understanding that advances in technology for sources under local air districts’ jurisdiction should contribute to future reductions. Until new mobile and stationary technologies become available, we propose to defer the issue of how to apportion long-term emission reduc tion obligations among responsible agencies. This issue will be revisited in future SIP updates. In the meantime, ARB would be responsible for all the long-term reductions upon SIP approval.

Proposed Mobile Source Strategy

The mobile source strategy has two distinct components – more stringent standards for new engines and cleanup of existing fleets. For passenger vehicles, ARB’s Low Emission Vehicle Program ensures that new vehicles entering the fleet are exce ptionally clean. The challenge is maintaining low emission levels over time and getting the oldest, dirtiest remaining vehicles off the road as soon as possible. The St ate Strategy proposes improvements to Smog Check and expansion of vehicle scrap programs to ac hieve these goals.

The biggest mobile source challenge is cleaning up legacy fleets of diesel engines – including trucks, construction and farm equipment, ships and locomotives. Emissions of NOx (nitrogen oxides) from diesel engines contribute

to both ozone and PM2.5 levels. Emissions of SOx (sulfur oxides) from ships are a significant contributor to PM2.5 levels. Directly emitted parti culate matter from diesel engines contributes to PM2.5 le vels. ARB has adopted a number of

measures to reduce emissions from di esel fleets under ARB’s 2000 Diesel Risk

Reduction Plan and 2006 Goods Movem ent Emission Reduction Plan.April 26, 2007 3 The proposed State Strategy would incorpor ate measures from these plans into

the California SIP. This includes new m easures for port tru cks, statewide truck fleets, ships traveling and in port, lo comotives, and harbor craft. These

measures would accelerate introducti on of newer, cleaner engines and, where available, require retrofit controls. T he cost of these measures will be in the

billions of dollars but these reductions are necessary to meet air quality standards and reduce the health and economic impacts of air pollution in

California.

The mobile source reductions rely prim arily on regulatory actions by ARB, BAR,

and U.S. EPA. International actions to require cleaner new ship engines and retrofits are also part of the longer-term strategy. Actions by the ports and private sector and public f unding would complement the regulatory strategies. However, the enforceable SIP obligati on to achieve the specified emission

reductions would rest with the Board.

The Board’s authority to regulate mobile sources varies by category and circumstance. Under California law, the Board can set new engine standards for mobile sources, but federal preemptions and practical limitations apply to many diesel engines categories. For example, under the federal Clean Air Act, only U.S. EPA can set new engine standards for locomotives and construction and farm equipment equipped with off-road engines less than 175 horsepower. In the case of new heavy-duty diesel trucks and ot her new and in-use off-road engines, ARB may establish emission standards, but must obtain a wa iver/authorization

from U.S. EPA befor e it can enforce such regulatio ns. The interstate nature of trucking makes national standards for new tr ucks a practical necessity. While not admitting preemption, we re cognize that U.S. EPA has the responsibility to represent California’s interests in the international standar d setting process for ocean-going ships. In short, ARB must re ly on the federal action to set the new technology standards that form much of the basis for ARB staff’s proposed measures to accelerate cleanup of legacy diesel fleets.

The timing of federal standards is an important part of the picture. California can only accelerate the introduction of cleaner technology once cleaner engines are

available. The cleanest NOx standards phase in for trucks in 2010 and between 2013-2017 for various types of constr uction and other off-road equipment. U.S. EPA has proposed more stringent NO x standards for new locomotives that would begin in 2017. ARB staff continues to make the case that these standards need to be implemented prior to 2014. While the interim standards now in place are contributing to current progress, t he magnitude of the reductions needed in the South Coast and San Joaquin Valley will ultimately require the cleanest technology in every diesel engine application.April 26, 2007 4 The proposed mobile source strategy and SIP commitments are described in Chapter 3. Individua l measures are described in more detail in Chapt er 5. The figure below shows the decrease in em issions for passenger vehicles, heavyduty trucks, and construction equi pment between now and 2014 with the proposed State Strategy. Due to increas ingly more stringent mobile source controls, emissions from these categorie s are all on a downward trend, despite growth in population, travel, and the economy. The new measures in the proposed State Strategy would accelerate these emissions reductions. ARB staff is proposing an aggressive new emission reduction commitment of 122 tons per day of NOx reductions in the South Coas t by 2014 in order to meet the region’s

PM2.5 attainment needs. This would bring the total mobile source NOx

reductions achieved between 2006 and 2014 to about 450 tons per day.

In contrast to passenger vehicles, tru cks, and construction equipment that show

substantial emission decreas es with natural fleet turnover, locomotive and ships

show an increase in emissions without t he proposed State Strategy. Locomotive emissions have been decreasing in the S outh Coast due to the accelerated

introduction of the cleanes t current technology (Tier 2). However, as shown below, growth overtakes this benefit by 2014. The proposed State Strategy

includes a measure to accelerate in troduction of the next generation of clean technology once U.S. EPA adopts its pr oposed new Tier 4 standards. The 2014 benefits assume Tier 4 engines becoming available in 2012. The 70 percent reduction projected for 2020 is based on t he proposed measure to accelerate the

introduction of Tier 4 locomotives to California.April 26, 2007 5

Proposed Consumer Products Strategy

Consumer products are expected to becom e the largest source of reactive organic gas (ROG) emissions in the South Coast and the third largest source in the San Joaquin Valley by 2020. The magni tude of the emissions indicates that

additional controls for this sector remain important, even though the average photochemical reactivity of the ROG emi ssions from consumer products is about

one-third that of motor v ehicle exhaust. The propos ed State Strategy would

continue ARB’s commitment to reduce ROG emissions fr om consumer products.April 26, 2007 6 Two new phases of control are proposed. One is under development for Board consideration by 2008 and t he other between 2010 and 2012. As part of ARB’s longer-term strategy, staff also proposes to explore additional market-based mechanisms to encourage the development, distribution, and purchase of cleaner, very low, or zero emitting products.

The table below shows the expected reductions from the proposed State Strategy in 2014 for South Coast and S an Joaquin Valley. The benefits of the State Strategy will increase over time . The expected reductions in 2020 and 2023, along with the proposed timefram es for staff development, Board consideration, and implementati on of the these measures is found in Chapter 3.

Emission reduction estimates for each proposed measure are shown for informational purposes only. Actual emission reductions from any particular measure may be greater than or le ss than the amounts shown.April 26, 2007 7 Major Issues

Bump Up to “Extreme” for Ozone

There is concern that the proposed Stat e Strategy does not provide sufficient

emission reductions to show attainment of the ozone standard earlier than the deadlines proposed in the South Coast and San Joaquin Valley SIPs. Both ozone SIPs propose an “extreme” classi fication for the 8-hour ozone standard

which sets an attainment deadline of 2024. Under the federal Clean Air Act, the

extreme classification carries with it an ability to rely on as yet undefined new technologies where necessary (section 182(e)(5)).

Both regions were previously classi fied as “extreme” for the 1-hour ozone standard based on the severity of their ozone problem. With the transition to the more stringent 8-hour standard, these distri cts were classified as severe-17, with an attainment deadline of 2021 (South Co ast), and serious, with an attainment deadline of 2013 (San Joaquin Valley), based solely on their ambient concentrations of ozone. In reality, bot h districts need more time to accomplish

the substantial emission reduction s required for attainment.

Air districts have the ability to request a reclassification, and in the case of a request to reclassify to “extreme,” U.S. EPA must grant the request. Since such a request frames a district’s attainment demonstration, ARB must also accept the reclassification request unless the Board re jects a district SIP as inconsistent with federal require ments.

The proposed reclassifications raise t he issue of how the 2024 attainment deadline will affect air qualit y progress and the health impac ts of air pollution in these regions. This is a very real conc ern. Accordingly, in the SIP development process considerable effort was devot ed to assessing whether these bump-ups

could be avoided.

ARB staff considered whether existing te chnologies, if applied across the board to all mobile and stationary sources, could achieve the necessary emission

reductions to attain sooner. Unlike ru lemaking processes, this analysis was performed for SIP development purposes without considering cost as a

constraint.

The analysis showed that all diesel fleets would need to turn over to the newest engine standards that phase in between 2010 and 2017, all pa ssenger vehicles would need to be no older than 10 years, and substantial additional reductions would be needed from new technologies for bot h mobile and stationary sources. The only other potential option for fully ac hieving the remaining reductions would be to constrain growth, business operati ons, and personal travel. Absent policy decisions to impose such restrictions, ARB staff believes it is necessary to make use of the new technology provision of the Clean Air Act. For the San JoaquinApril 26, 2007 8 Valley, about 10 percent of the necessary reductions would fall in this category. For the South Coast, it would be about 25 percent of the necessary reductions.

To address concerns about delays in attain ment, ARB staff proposes to continue to identify and pursue additional actions t hat would further accelerate air quality progress. While it is un likely that the entire ozone a ttainment gap will be filled without new technology, staff believes add itional progress coul d be made if, for example, more incentive funds became avai lable. Also, as regions move closer to attainment, episodic “s pare the air” type programs may be able to provide the

final increment of reductions needed a fe w days per year. Public education and outreach to encourage voluntary actions have historically been key elements of these programs.

South Coast PM2.5 SIP

How the SIP should address the PM2.5 attainment chal lenge in the South Coast continues to be controversial. The pr oposed State Strategy along with district measures leaves an emission reduction gap in the South Coast’s proposed

attainment demonstration of about 70 tons per day of NOx in 2014. The South

Coast air district staff ha s identified a set of measur es -- mobile source NOx measures -- for ARB to adopt to close the gap. This would be above and beyond the 451 tons per day of NOx reductions in the proposed State Strategy. ARB staff believes the District’s suggested mob ile source measures are not feasible

without billions of dollars of unidentified subsidies to expedite the introduction of the newer, cleaner diesel vehicles and equipment.

ARB technical staff has reviewed Sout h Coast’s proposed PM2.5 attainment

demonstration and identified additional local m easures to reduce directly emitted particulate matter. ARB staff believes these measures can bridge the gap and achieve the standard by 2014. These measures would reduce emissions from residential wood smoke, restaurant cook ing, and dust-generating activities. The ARB staff’s analysis and the peer re view of the staff methodology are discussed in Chapter 4.

It is important to recognize that the pr ojected gap in reductions is based on a modeling assessment that is more pessi mistic than the measured air quality trend. Between 2001 and 2006, the m easured PM2.5 annual average dropped from 30 to just over 20 ug/m 3 consistent with the downw ard emissions trend. If that trend continues, the emission reducti ons in the proposed State Strategy will

be sufficient for attainment. The Sout h Coast predicts that with ARB staff’s proposed State Strategy, the highest remain ing concentration in 2014 would 15.7 ug/m 3 -- less than one micr ogram above the 15 ug/m 3 standard. Even if that modeling is correct, ARB’s alternative attain ment strategy would close that gap.April 26, 2007 9

In light of the measured PM2.5 progr ess over the past 15 years, and the magnitude of the new emission reductions t hat will occur, ARB staff believes that

the South Coast will attain the PM2.5 standard by 2015 with the mobile source measures in the proposed State Strategy. Nonetheless, to be health protective

and meet U.S. EPA SI P modeling requirements, staf f believes that additional feasible measures should be pursued. Using the South Coast model, ARB staff found that the proposed local measures for residential wood smoke, restaurant cooking, and fugitive dust w ould close the apparent gap.

Proposed Action

Staff is recommending that the Board adopt the proposed State Strategy to meet

both ozone and PM2.5 attainment needs in the South Coast Air Quality Management District and the San Joaquin Valle y Air Pollution Control District at ARB’s June 21-22, 2007 public meeting. T he State Strategy, in combination with near-term local air district measures, must meet the emission reduction target in each region’s attainment demonstration.

The sequence of public meetings to cons ider the various SIP elements is:

• April 30, 2007 – San Joaquin Valle y Air Pollution Control District Governing Board consideration of the San Joaquin Valley Ozone Plan.

• June 1, 2007 (tentative) – South Coast Air Q uality Management District Governing Board consideration of the South Coast Air Quality Management Plan.

• June 14, 2007 – ARB consideration of San Joaquin Valley Ozone Plan.

• June 21-22, 2007 – ARB consideration of the proposed State Strategy and South Coast District Air Quality Management Plan for ozone and PM2.5.

• April 2008 – Completion of San Joaquin Valley PM2.5 SIP.April 26, 2007 10 Next Steps

Once local plans and the State Strategy are approved by the local and State governing boards, they are submi tted to U.S. EPA for approval.

SIPs are generally updated on a triennial basis for regions with the most persistent air quality probl ems. When U.S. EPA revises national ambient air quality standards, new SIP planning processes are triggered. U.S. EPA recently tightened its 24-hour PM2.5 st andard and is currently reviewing the 8-hour ozone

standard. Final U.S. EPA action on the 8-hour ozone standard review is expected by March 2008.

### 1. BACKGROUND

General SIP Requirements

California’s 2007 State Implementation Plan s (SIPs) are a comb ination of State and local air quality planning documents that must show how California will meet

federal the 8-hour ozone st andard statewide. The S an Joaquin Valley, South Coast Air Basin, Sacramento region, S an Diego, Ventura, and a number of air

districts downwind of urban areas are nonattainment for the ozone standard. Ozone SIPs must be submitted to U.S. EPA by June 15, 2007.

This document is the State’s emission redu ction strategy for sources of pollution under State and federal authority (State Stra tegy), and, for every local region not meeting federal standards, a demonstration of how at tainment of the 8-hour

ozone standard will be achieved.

In addition to ozone SIPs, the South C oast and San Joaquin Valley must prepare PM2.5 SIPs for submittal to U.S. EPA by April 5, 2008. For the South Coast Air Basin, the South Coast Air Quality M anagement District is developing a PM2.5 SIP in parallel with the ozone SIP. The San Joaqui n Valley PM2.5 SIP in on

track to be submitted in 2008.

The 2007/2008 ozone and PM2.5 SIPs are another step in the air quality planning process that over the years has helped define new actions to improve California’s air quality. ARB has adopted a series of regulations over the past 10 years to implement measures in the 1994 ozone SIP, as well as additional new

ARB measures identified in the 2003 SIP update. New mobile source regulations, reformulated gasoline, and mu ltiple consumer products regulations

envisioned in these SIPs have been adopted and are being implemented today. And, while California has serious air qua lity challenges ahead, it is important to recognize the progress made as a result of California’s landmark air pollution control programs. With that experience and history of success, we need to continue to do more. ARB staff recogni zes the importance of the new State measures and are proposing a full slate of new measures for development and consideration by the Board.April 26, 2007 12 National Air Quality Standards

The U.S. EPA adopts standards for ambient (outdoor) air pollutants designed to protect public health. Ext ensive studies on the health effects of air pollution

worldwide have confirmed the importance of conti nuing to reduce people’s exposure to air pollution. U.S. EPA is required to review its air quality standards every five years.

In July 1997, the federal government announced new national ambient air quality standards (NAAQS) for the pollutants oz one and particulate matter (PM). The new standards provide more protection from the harmful health effects of these pollutants. The ozone standard was revised to protect against longer pollutant exposure periods by requiring that ozone concentrations not exceed specified levels over an 8-hour period instead of a 1-hour period. A new particulate matter standard was added to protect against the smaller inhalable particles, less than two and a half microns in diameter (PM2 .5). Air quality standards have become more stringent over time as new studies have shown adverse health effects at

lower levels. The standards below are the current benchmar k for federal SIP requirements. U.S. EPA is currently reviewing the adequacy of the current 8-hour standard. And in December 2006, U.S. EPA adopted a more stringent

24-hour PM2.5 standard of 35 micrograms per cubic meter. This will likely mean that several new areas will be required to prepare a plan to attain the newer

standard. Initial State recommendations for nonattainment areas are due in late 2007, with final nonattainment areas det ermined by U.S. EPA in early 2010.

Plans for the revised 24-hour standard will be due in 2013, with attainment dates to be determined after U.S. EPA issues transition guidance.

Ozone Standard PM 2.5 Standards

How much more stringent is the 8-hour ozone standard than the 1-hour ozone standard? The two maps on the following page illustrate a dramatic difference in exceedance days (number of days that vi olated the standard) for the 1-hour

standard versus the 8-hour standard in the S outh Coast air basin in 2005. While many areas of California continue to be in violation of federal air quality standards, real air quality pr ogress has been made, as we will illustrate later. The clean air bar simply continues to be raised as we learn more about the health effects of air pollution.

in the South Coast Air BasinApril 26, 2007 14 Health Effects of Ozone and PM2.5

Ozone

The formation and health impacts of ozone are very well studied. Ozone is a highly reactive gas that forms in the atmosphere through complex reactions between chemicals directly emitted from motor vehicles, industrial plants, consumer products and many other sources. It forms in gr eater quantities on hot, sunny, calm days making the summer season the key exposure period.

Considerable research over the pa st 35 years has investigated how people respond to inhaling ozone. These studi es have consistently shown that

inhalation of ozone can lead to inflammati on and irritation of the tissues lining the human airways. This causes the muscle cells in the airways to spasm and contract, thus reducing t he amount of air that can be inhaled. Symptoms and responses to ozone exposure vary widel y, even when the amount inhaled and length of exposure is the same. Typi cal symptoms include cough, chest tightness, and increased asthma symptoms. Ozone in sufficient doses can also increase the permeability (“leakiness”) of lung cells, making them more susceptible to damage from envir onmental toxins and infection.

Medical studies of large populations have found that ozone exposure is associated with an increase in hospital admissions and emergency room visits, particularly for lung problems such as asthma and chronic obstructive pulmonary

disease. Several studies have also associated ozone exposure with increased premature mortality in el derly people with chronic diseases of the lungs and circulatory system.

People who exercise or wo rk outdoors are at greater ri sk of experiencing adverse health effects from ozone exposure because they inhale more ozone. Current

evidence has linked the onset of asthma to exposure to elevated levels of ozone in exercising children. Children a nd adolescents are at increased risk because they are more likely to spend time out doors engaged in vigorous activities than adults and because they inhale more ozone per pound of body weight.

PM2.5

Particulate matter (PM) air pollution is also well studied. Particulate matter pollution is a complex mixtur e that consists of dry so lid fragments, solid cores with liquid coatings, and small droplets of liquid. PM ca n be directly emitted into

the air in forms such as dust and soot. It can also be formed in the atmosphere from the reaction of various gases. Part iculate matter is less than 10 microns in diameter (a micron is one -millionth of a meter) and is called PM10. Even smaller particles, those 2.5 microns or less in di ameter, are called “fine particles” or PM2.5, and are the target of this SIP. PM2.5 is a component of PM10.April 26, 2007 15 Extensive research has shown that PM c an be inhaled into the deep portions of the lungs. Some inhaled particles are exhaled again, but others deposit in the lungs, which can lead to inflammation in both the lungs and the circulatory system. PM2.5 poses an increased health risk because it can penetrate deeper into the lungs and may also enter the bloodstream.

Population-based studies in hundreds of cities around the world have demonstrated a strong link between elevat ed particulate matter levels and premature death in people with pre-existing heart or lung disease. The two most important of these studies were performed in many cities in the United States, and have been ongoing for over 15 years. Both of these studies found a strong relationship between long-term PM exposure and premature death.

Scientists have observed higher rates of hospitalization, emergency room visits and doctor’s visits for respiratory illne sses or heart disease during times of high PM concentrations. During these periods of high PM levels, scientists also observed the worsening of both asthma symptoms and acute and chronic bronchitis, and reductions in vari ous measures of lung function.

The elderly and people with heart and/or lung di seases are particularly at risk of experiencing adverse effects from PM ex posure. Studies have also shown that children may be particularly vulnerable to PM effects. There is evidence from the 10-year Children’s Health Study funded by the ARB that in communities with high levels of PM children's lungs develop more slowly and that at maturity they tend to have lower lung capacity than children who grow up in communities with lower levels of PM. Just as with ozone, child ren and infants may also be more at risk of experiencing adverse effects from PM because they inhale more air per pound of body weight than do adults, they breat he faster, and have smaller body sizes. In addition, there is some evidence t hat children's immature immune systems may cause them to be more su sceptible to PM than adults.

Nonattainment Areas and Air Quality Trends

Geographic areas that exceed a feder al air quality standard are called nonattainment areas. A comprehensive network of monitoring stations throughout California measures air qualit y and provides the data necessary to

determine whether an area meets or exceeds federal ozone and PM2.5 air quality standards. 1

Compliance with the federal ozone and PM 2.5 standards is based on pollutant concentrations, measured at a comprehens ive network of monitoring stations throughout California, averaged over three years. These three-year averages

are called design values . Air quality monitoring in the years 2001 through 2003

1 More about California’s air quality monitori ng network can be found on ARB’s website at: http://www.arb.ca.gov/aaqm/aaqm.htmApril 26, 2007 16 was used by U.S. EPA to designate 15 areas in California as nonattainment for

the federal 8-hour ozone standard. The San Joaquin Valley and South Coast Air

Basin are also nonattainment for PM2.5.

A specific year’s design value is averaged over three years. For example, the design value for the year 2001 reflects the averages for the years 1999, 2000, and 2001. Ozone design values are an average of the fourth highest

concentrations for each of the last thr ee years. Design values for the PM2.5 annual average reflect annual average (arithmetic mean) concentrations averaged over the last three years. T he PM2.5 24-hour design values reflect the

98 th percentile concentrations averaged over the last three years.

For the ozone standard, areas are classi fied based on the severity of the problem. In descending order in terms of magnitude of the problem, the

classifications are extreme

, severe

, serious

, moderate , and marginal . The Clean Air Act provides more time to meet the standard based on the severity of the problem. Based on its classification an ar ea is given an attainment deadline. A special designation, called basic , refers to nonattainment areas governed under a separate set of requirement s in the Clean Air Act. Fo r PM2.5, U.S. EPA simply designated the South Coast and San J oaquin Valley as nonattainment withoutApril 26, 2007 17 application of the classification scheme used for PM10. This results in an

attainment deadline of 2015.

Ventura County Moderate / Serious 2010 / 2013 or 2019 Imperial County Marginal 2007 San Francisco Bay Area Marginal 2007

The above table lists the marginal through extreme nonattainment areas

for the federal 8- hour ozone standard, while the table to the right lists the areas with the special basic ozone nonattainment designation. The Clean Air Act allows changing of nonattainment designations and the

extension of the attainment deadline if the State believes a change is needed after analyzing the nature of the ozone problem and c hallenges to meet the

standard. So the above table includes t he current attainment designations, as well as designation changes that may be needed based on regional analyses.

For this set of SIPs, U.S. EPA has provided guidance on how to interpret the

attainment deadline as it relates to attainment demonstrations. The question arises because the deadlines are mid-y ear. The ozone attainment deadline is June 15 and the PM2.5 deadline is April 5 of the attainment year. To address the issue, U.S. EPA guidance calls for the analysis of attainment to be done for the year prior to the actual attainment year . So in this document we will be showing emission reduction targets and emissions fo r the year prior to the attainment year. For example, if the attainment year is 2024, we will be showing emission reduction targets and emissi ons for the year 2023.

Development of State Strategy

In developing our proposed statewide em ission reduction strategy, ARB staff worked closely with air districts on atta inment demonstrations for ozone for each

area and on a PM2.5 attainment demonstr ation for the South Coast

. In that process, emissions inventories are dev eloped and air quality models are used to establish a region’s “carrying capacity” and to calculate the additional emission

reductions needed for attainment.

The emission reduction targets serve th ree purposes. First, they provide an

indication of how far the existing control program will take each region towardApril 26, 2007 21 attainment and if additional reductions fr om new measures are needed. Second, they indicate how much time a region may need to reach the standards and if a classification change to a later attainment date is likely needed. And third, they provide a benchmark for designing new emission reduction measures.

The magnitude of the attain ment challenges in the S outh Coast and San Joaquin Valley, as shown in the next chapter, ar e the drivers for ARB staff’s proposed statewide strategy. The new SIP measures are also needed for the Sacramento region, the Coachella Vall ey, and the Antelope Valley and Western Mojave

Desert nonattainment area. California’s other ozone nonattainment areas, including San Diego and Ventura, are pr ojected to attain by their assigned deadline based on the benefits of pr eviously adopted SIP measures.

Given the severity of the ozone problems in the South Coast and San Joaquin Valley, both regions have indicated in thei r draft air quality plans that they will be requesting a reclassification to extreme with attainment deadlines of 2024. The

2015 PM2.5 deadline and the South Coas t PM2.5 carrying capacity framed staff’s analysis of new near-term measures. The other key driver for developing new SIP strategies is to reach ozone attainment in both regions as quickly as possible.

Chapter 2 will summarize the process of determining the emission reduction targets and show those targets for the S outh Coast and San Joaquin Valley. The process consists of developing an emissions inventory and performing data analyses and air quality modeling based on that inventory to establish the

emissions limits that ensure air quality standards are met.

Air Pollution Transport

Air pollution transport, by definition is quite simple – air movements carry pollutants from one area to anot her. In reality, air po llution transport is a very complex phenomenon. It is three-dimensional and can o ccur at ground level or aloft in upper air levels. With modeling for the State being split into two modeling

domains – one for Northern and Centra l California and one for Southern California – transport relationships bet ween air districts within these large domains are implicitly capt ured within the models. This is the mechanism ARB uses in its oversight role to ensure transport impacts on downwind areas are addressed for purposes of both State and f ederal air quality standards. In terms of attainment demonstrations, inputs to the modeling for a downwind area include forecasted emission reductions in upwi nd areas. This way the attainment

demonstration takes into account t he shared responsibility for reducing emissions in regions where air polluti on transport can at times be significant.April 26, 2007 22 Other Programs

In addition to SIPs, ARB has multiple plans and programs to reduce air pollution throughout California. Emission reducti on strategies from many of these programs are taken into account in the ozone and PM2.5 SIPs.

ARB Goods Movement Plan

The Emission Reduction Plan for Ports and Goods Movement in California, approved by ARB in April 2006, is one of t he main contributors of new measures necessary to meet federal air quality st andards. Most goods that move within and through California do so by truck. Ships are the largest source of SOx emissions in the State. Heavy-duty tru cks are the largest statewide source of NOx emissions. These air pollution realit ies make it impossible to tackle the PM2.5 challenge without addressing goods movement emissions. Likewise, emission reduction targets for ozone will not be met without reducing emissions related to goods movement.

The strategies included in the goods mo vement emission reduction plan target ships and trucks, as well as the other three main sources of goods movement emissions: harbor craft, cargo handling equipment, and locomotives. By 2020, these strategies will cut statewide goods movement emissions of NOx by 63 percent, SOx emissions by 78 percent, and will also reduce the statewide health risk from goods movement-related di esel particulate matter 85 percent.

Work on many of the strategies in t he goods movement emission reduction plan is underway and serves as the starting poi nt for near-term actions to meet the emission reduction targets for the SIPs. These strategies will provide essential new emission reductions needed for regional attainment, while they reduce the air pollution-related health risk for thos e who live near our ports, railyards, distribution centers, and other goods movement facilities.

ARB Diesel Risk Reduction Plan

An important source of dire ctly emitted PM2.5 is diesel exhaust. The particulate matter from diesel-fueled engines (diesel PM) has been singled out as a particularly harmful pollutant and identified as a toxic air contaminant by the Air Resources Board in 1998. Nearly 70 perc ent of the known cancer risk caused by

air toxics is attributed to diesel PM . In 2000, ARB adopted a plan to reduce diesel PM emissions 85 percent by 2020, and has since adopted a number of regulatory measures to reduce diesel PM emissions statewide. Additional measures are under development. Diesel PM control measures in the plan are reducing both direct diesel PM and NOx emissions through a combination of engine retrofits and replacements. Upcomi ng mobile source fleet measures to

reduce diesel PM and NOx emissions are a critical part of t he new SIP strategy

as well the Diesel Risk Reduction Plan.April 26, 2007 23 Environmental Justice

The SIPs consist of strategies designed to bring a region’s air quality into compliance with federal standards. SIPs must be designed to ensure air quality standards throughout the ent ire region, so achiev ing air quality standards provides public health benefits to every community. This makes SIP implementation important to meeting ARB’s communi ty health and environmental justice goals. As part of our environmental justice progr am, ARB has initiated air quality studies in several communities and continues to focus resources on

mobile source enforcement in environm ental justice communities. ARB’s Air Quality and Land Use Handbook, approved by ARB in May 2005, provides guidance to help improve local land use decisions that can negatively impact public health at the community level.

ARB’s SIP strategies have a significant nexus to community health due to the emphasis on cleaning up the legacy fleets of diesel engines. Much of the large equipment and vehicles that help constr uct our buildings and highways and move our goods are not well controlled and have very long lives. Adopting rules to clean up these fleets will have an imm ediate and significant effect on the

communities where these sources are concentrated.

Regional Haze

The same particulate air pollutants that affect public health also extinguish and scatter light, thereby obscuring visibility. The federal Clean Air Act set the farreaching goal of achieving natural visibility conditions by 2064 in the nation’s most treasured parks and wilderness areas. Of the 156 designated areas, 29 are in California, managed by the National Park Service and the U.S. Forest Service. Therefore California is working in conc ert with fourteen other western states to reduce controllable emissions of particulate s so that regional haze is reduced in the western region of the country. In 1999, the U.S. Environmental Protection Agency published rules to guide the preparation of Regional Haze State Implementation Plans to reduce regional haze.

ARB is currently preparing the first regi onal haze plan for the entire State, for transmittal to EPA by the December 17, 2007 deadline. General trends in

California since the 1990s show that emi ssion controls are improving visibility in our parks and wilderness areas . The regional haze plan will show how these controls constitute reasonable progress alo ng the path to natural visibility. In 2012, ARB will conduct a mid-course review of measured visibility changes and analyze how emission reductions implem ented to achieve the 8-hour ozone and

the PM2.5 standards will move the State further along the pat h to natural visibility

in the future.April 26, 2007 24 Climate Change

ARB’s implementation of the Global Warmi ng Solutions Act of 2006 (AB 32) is a major new effort just underway. These activities, in cluding future rulemaking, will occur on a parallel but separate track as we proceed with implementation of our SIP strategies. The statutory requirements and timelines are different, so it is not appropriate to include potent ial co-benefits of greenhouse gas strategies in SIP documents at this point. However, as greenhouse gas reduction measures are developed and adopted, ARB staff will do the necessary technical work to determine the impact on ozone and PM2.5 prec ursor pollutants.April 26, 2007 25 

### 2. TECHNICAL FOUNDATION

Emissions Inventory Overview

Developing attainment strategies requi res an understanding of the sources of pollution, the quantities em itted, their geographical distribution, and how air pollution controls and growth will impact future emission levels. There are multiple types of emission inventorie s used in air quality programs including annual averages, seasonal, and day-specific m odeling inventories. SIPs rely on region specific inventories that may diffe r from the statewide picture. In the regulatory development proc ess emission inventories are typically refined since inventory data is a key input for cost -effectiveness evaluations. This is an important inventory improv ement mechanism, and ARB staff incorporates these updates into the statewide inventory.

The emissions inventory serves three pr incipal roles in the SIP process:

• It provides a primary input to t he modeling necessary to determine the emission reductions needed for attainment;

• It supplies comprehensive emissions information for the development of emission reduction strategies;

• And after the SIP is approved, it is used to track progre ss of the emission reduction commitments outlined in the plan.

California is a diverse State with many sources of air pollution. ARB, in cooperation with local air districts, mainta ins a statewide emissions inventory. The inventory is constructed based on four major emission categories:

• Stationary Sources -- generally in dustrial facilities, which can be identified by a name and location.

• Areawide Sources -- either sma ll individual sources, such as residential fireplaces, or widely di stributed sources that cannot be tied to a single location, such as consumer products and dust from unpaved roads.

• On-Road Mobile Sources -- includes on-road cars, trucks, buses, etc.

• Off-Road Mobile Sources -- includes off-road vehicles such as boats, off-road recreational vehicles, airc raft, trains, ships, industrial and construction equipment, farm equipment, and other equipment.

The statewide emissions inventory develope d by ARB and the local air districts

includes all the main sources of emissions – all of the many on-road and off-road

mobile sources and all the various stat ionary and areawide sources. Estimating

the amount of emissions statewide and in each region is done by summing the

emissions from each source. The statewide inventor y for the 2007 SIP development uses ARB’s November 2006 on-road motor vehicle model (EMFAC)

and ARB’s off-road mobile source model . Stationary source emissions areApril 26, 2007 26 provided by local air districts. The regional SIP inventories are discussed in Chapter 5, Regional SIP Summaries.

Precursor Pollutants

Air pollutants that react to form ozone and PM2.5 in the air are called precursor pollutants. For ozone, the main precur sor pollutants are nitrogen oxides (NOx) and reactive organic gases (ROG). There ar e four main precursors of PM2.5: NOx, ROG, sulfur oxides (SOx) and ammoni a (NH3). PM2.5 can also be directly emitted into the atmosphere (direct PM2.5) in various forms that include smoke from fires, dust from paved and unpaved roads, and particle emissions from the burning of fossil fuels.

PM2.5 pollution is a complex mixture and air quality modeling is used to assess the relative effectiveness of reducing each precursor pollutant as well as directly emitted PM2.5. Current data analysis and air quality modeling indicates that two of the four precursors , NOx and SOx, are signifi cant in reducing PM2.5 concentrations in the South Coast, and that the PM2.5 emission control strategy would be served best by focusing on reduc ing emissions of t hese two precursor pollutants. There is also a small PM2.5 benefit from ROG emission reductions,

but benefits from ammonia emission reducti ons were found to be insignificant. Reducing direct PM2.5 is also an effective strategy according to recent modeling.

NOx . Nitrogen oxide emissions are produc ed by the combustion of fuels in engines, furnaces, or fires. Today mob ile sources make up about 85 percent of

the total statewide NOx emissions. Th is percentage decreases over time as

motor vehicle fleets become cleaner. Emissions from less clean sources like locomotives, ships, and aircraft continue to grow. Stationary sources of NOx include combustion processes in indus tries such as manufacturing, food processing, electric utilities, and petroleum refining. Areawide sources of NOx, which include waste burning and residential fuel combusti on, contribute a smaller portion of total NOx emissions. Air qualit y science indicates that reductions of

NOx are more beneficial than reductions of other pollutants to help meet both ozone and PM2.5 standards, and t herefore NOx is a majo r focus of the State Strategy.

ROG . Reactive organic gases result primar ily from incomplete fuel combustion and the evaporation of chemical solvents an d fuels. Stationary sources of ROG include processes that use solvents such as dry cleaning, degreasing, and coating operations. Today mobile s ources are the largest ROG emissions category. However, other ROG categories become relatively more important

over time. Areawide ROG sources which grow directly with population begin to dominate in the future so that by 2020 c onsumer products is the largest source category.April 26, 2007 27 SOx . Sulfur oxide emissions are dominat ed by the mobile source category of ships and commercial boats. Evaporative losses from petroleum refining (a stationary source) are another significant source of SOx. The other sources that make up 5 percent or more of the SOx inventory ar e locomotives and mining and cement manufacturing.

Direct PM2.5 . Directly emitted PM2.5 comes main ly in the form of smoke, soot, and dust particles. Major sources in clude managed burning and agricultural burning; dust generated by vehicles traveling on paved and unpaved roads, residential fireplaces, cooking and fuel co mbustion; and particle emissions from diesel-fueled engines on trucks, ships, and construction equipment. While soot from diesel engines is not a major porti on of the entire dire ct PM2.5 emissions inventory, it is a major health concern, as it is a toxic air contaminant that can cause premature death.

Forecasting Future Emissions

Estimates of projected future emissi ons depend on two independent variables: growth and control. Different methods ar e used to estimate t he future growth of emission sources based on their type. And future emission controls are incorporated into the projected emi ssions for each source category based on when the controls are implemented, how much the controls reduce emissions, and how many units (vehicles, consum er products, etc.) are affected.

The charts on the next page show the change in total projected statewide emissions for NOx, ROG, and SOx from 2006 to 2023 and the relative emissions change in each of these emission source categories. They reflect projected growth in each category combined with the benefits of the existing control program (those emission controls adopted prior to 2007). For example, SOx emissions as a category continue to grow due to ship emission increases. This makes ship SOx emissions a high priority for control in the new SIP strategy. NOx and ROG emissions are decreasing as a result of existi ng control programs despite substantial growth in population, travel, and the economy.

ARB uses two computer models to simu late and forecast emissions for on- and

off-road sources. For cars , sport utility vehicles, minivans, and trucks, ARB used

EMFAC2007. For off-road vehicles and equipment, ARB used OFFROAD2007. Both models were released for public us e in November 2006 after a multi-year development process. As required by federal guidance, EM FAC2007 uses the

latest fleet information for vehicles age and population. The data is developed from the California Departm ent of Motor Vehicle registration data through 2005. For SIP purposes, as required by State law, vehicle activity is based on local transportation agency projections, or Calif ornia Department of Transportation data, if local data are not available.April 26, 2007 28 NOx Emission Forecast 2006-2023

Top Emission Sources

While the top emission categories are mobile sources in all California’s nonattainment areas, there is variability in the relative contribution of different sources by region. This makes the over all statewide emission reduction strategy more challenging and will affect the priorities of local control plans. For example, controlling the emissions from ocean- going vessels will have a tremendous impact on SOx emissions in the South Coas t and therefore is essential to that region’s PM2.5 control plan. Reduc ing SOx from ships has much less consequence in the San Joaquin Valley, so increased NOx reductions from

combustion sources will become even more important for t he Valley’s PM2.5 control strategy. The tables on t he next two pages show the top emission

sources of both NOx and ROG in the South Coast and the San Joaquin Valley.April 26, 2007 29 Here are some things we have learned by analyzing the emissions inventory for

these two areas:

• South Coast NOx emissions are signi ficantly impacted by goods movement, with the ships, trains, trucks, and off-road equipm ent that move goods contributing about 30 percent of all South Coast NOx emissions. Aircraft NOx emissions are also increasing.

• The impact of goods movement in the San Joaquin Valley is felt mostly by the

emissions contribution of heavy-duty trucks, which are projected to remain the largest NOx emitter through 2023.

• Emissions of NOx from manufacturing and industrial sources in the San Joaquin Valley become increas ingly significant as em issions from mobile

sources decline in the future.

• The large population in the South Coast is the ma in reason why consumer product emissions are projected to become the number one ROG emissions source by 2014.

• San Joaquin Valley ROG emissions are significantly impacted by agricultural

sources such as livestock waste.

• The existing emission control program will cut heavy-duty truck NOx emissions about 70 percent in the San Joaquin Valley and South Coast by 2023, but they need to be cut even more by new strategies to attain ozone

and PM2.5 standards.

• Mobile sources under federal and inte rnational jurisdiction (like ships, locomotives, and aircraft) contribute an in creasingly greater proportion of total emissions, especially NOx, in future years as emission increases due to growth overwhelm the existing contro l program, while emissions of mobile sources under State jurisdiction de crease due to stringent controls.April 26, 2007 30 South Coast Air Basin – Top Sources of NOx Summer emissions, tons per day

Note: Emissions do not include impact of State Strategy proposed new measures.April 26, 2007 32 Setting the Emission Reduction Targets

U.S. EPA rules require the use of air qua lity modeling to set emission reduction targets. Modeling is also helpful in gui ding the selection of the most effective pollutants to control. To set ozone em ission reduction targets, air quality modeling has been conducted separately for tw o overarching areas. One area is Northern and Central California, encompas sing the San Joaquin and Sacramento Valleys, the Bay Area and the Sierra Ne vada Mountains. ARB staff has been doing this modeling. The ot her area is Southern Califor nia, including the South Coast Air Basin, Ventura C ounty, Imperial Count y, and the Mojave Desert area. The South Coast air district has been doing this modeling. The South Coast air district has also been performing the air qual ity modeling to set its PM2.5 target.

Weight of Evidence Analysis

A Weight of Evidence analysis provides a set of complementary analyses that supplements the SIP-required model ing. These analyses can include consideration of measured air quality, emissions, and meteorological data, evaluation of other air qual ity indicators, and additiona l air quality modeling. A Weight of Evidence approach looks at the entir ety of the information at hand to provide a more informed basis for the at tainment strategy. While all analysis methods have inherent strengths and weak nesses, examining an air quality problem in a variety of ways increases t he confidence one has in the results. This approach also provides a better understanding of the overall problem and

the level and mix of emissions controls needed for attainment.

The discussion in Chapter 4 about South C oast PM2.5 pollution is a weight of evidence approach. More detailed weight of evidence analysis will be included in ARB staff reports on the local air district plans and in the local plans themselves.

South Coast Ozone Emi ssion Reduction Targets

Under State law the South Coast air distri ct is responsible for setting carrying capacities for the South Coast Air Basin. While the carrying capacities result in large emission reduction targets fo r both NOx and ROG, the South Coast modeling indicates that NO x reductions are more effective at reducing ozone in the long run, although ROG reductions are still needed to maximize progress. In fact, the air district modified the South Coast Air Basin carrying capacity in its February 2007 draft air plan, relying ev en more heavily on NOx reductions than

in its earlier estimates.April 26, 2007 33 The emission reduction targets based on the February 2007 carrying capacities are presented below.

It will be important to revisit the relative carrying capacities in subsequent SIPs to factor in inventory improvement, u pdated modeling, and control measure development.

South Coast PM2.5 Emission Reduction Targets

As discussed previously, unlike ozone, PM2.5 consists of many different components. These components can vary by location and season, with both local and regional scale cont ributions. This complexity and variability presents a unique challenge in modeling for attain ing the annual standard, and introduces a higher level of uncertainty in the results. In addition, while there is a long history and body of experience for ozone model app lication, air qual ity modeling for PM2.5 is relatively more recent, and it has not been applied as extensively. ARB

will continue to work with air distri cts on efforts to refine PM2.5 modeling techniques.

ARB staff has been using photochemical models for Northern and Central California developed as part of the mu lti-million dollar Central California Air Quality Study. This modeling continues to confirm that NOx is the key to long term attainment in the San Joaquin Valley. (This is also true for the Sacramento Valley and the rural regions downwind.) ROG looks benefi cial especially in the near term for maximum progress and to supplement NOx reductions long term.April 26, 2007 34 The ozone emission reduction targets for San Joaquin Valley are shown in the following table.

### 3. ARB’s 2007 SIP STATE STRATEGY

The State Strategy maps out how to ac hieve the emission reductions necessary to meet federal air qua lity standards. The two main emission reduction components of the State St rategy are the adopted SIP measures and proposed new measures. The adopted SIP meas ures include those adopted through 2006. Proposed new measures incl ude those to be adopted after 2006.

Responsibility for implementing emission reduction measures is shared between the agencies with primary respon sibility for controlling air po llution in California: the Air Resources Board, 35 local air pollution control and air quality management districts, and the U.S. Enviro nmental Protection Agency. However, given the current status of statewide emissions, AR B has the lion’s share of responsibility, followed by U.S. EPA.

Agency Roles in SIP Measure Development

Local Measures

Local air districts are pr imarily responsible for controlling emissions from stationary and areawide sour ces (with the exception of consumer products) through rules and permitting programs. Ex amples include industrial sources like factories, refineries, and power plants; co mmercial sources like gas stations, dry cleaners, and paint spray booth operations; residential sources like fireplaces, water heaters, and house paints; and mi scellaneous non-mobile sources like emergency generators. Distric ts also inspect and test fuel vapor recovery systems to check that such system s are operating as certified.

State Measures

ARB is responsible for controlling emissions from mobile sources (except where federal law preempts ARB’ s authority) and consumer products, developing fuel specifications, establishing gasoline v apor recovery standards and certifying vapor recovery systems, providing tec hnical support to the districts, and overseeing local district compliance wit h State and federal law. The Department of Pesticide Regulation is responsible fo r control of agricultural, commercial and structural pesticides, while the Bureau of Automotive Repair runs the State’s Smog Check programs to ident ify and repair polluting cars.

Federal Measures

U.S. EPA has the authority to control emissions from mobile sources, including sources all or partly under exclusive feder al jurisdiction (like interstate trucks, some farm and construction equipment, airc raft, marine vessels , and locomotives based in this country). U.S. EPA also has oversight authority for state air programs as they relate to the federal Clean Air Act. International organizations develop standards for aircra ft and marine vessels that operate outside the U.S.April 26, 2007 36 Federal agencies have the lead role in r epresenting the U.S. in the process of developing international standards.

Adopted SIP Measures

Many measures already adopted by lo cal, State and federal agencies are currently reducing emissions. Many will do so at an accelerated rate in the future. Some adopted measures are schedul ed to go into effect years hence. Adopted SIP measures will have a very si gnificant impact on emissions and air quality between now and the target dates (atta inment years) in the areas of the

State that do not meet federal ozone and PM2. 5 air quality standards.

Adopted SIP measures have been develo ped over the years through the combined efforts of air pollution regulat ors – with a foundation of ARB’s mobile source and fuels programs, complementar y national actions for pollution sources under federal authority, and local air di strict programs fo r industrial and commercial sources -- as well as transpor tation plans that integrate transit and

other alternatives to solo vehicle tr avel. ARB has adopted 46 emission-reducing control measures since the approval of the 1994 1-hour ozone SIP. These measures, shown on the table on Page 38 entitled “Air Resources Board SIP Control Measures (1994-2006),” comprise the bulk of the benefit s of the adopted

measures.

Mobile Sources

Cleaner Engines and Fuels

California has dramatically tightened em ission standards for on-road and off-road mobile sources and the fuels that power them. The table below shows how significantly the adopted measures have c ontrolled emissions from new engines for the major categories of mobile sources.

California’s emission control program fo r on-road motor vehicles is the strongest

in the world. New cars are now 99 percent cleaner than their uncontrolled counterparts. Trucks are now 90 perc ent cleaner, and will be 98 percent cleaner by 2010.

Working in concert with t he U.S. EPA, standards for goods movement sources have also been tightened dramatically. By requiring low-sulfur fuel, SOx emissions from ship auxiliary engines will be cut 96 percent by 2010. New locomotive engines are now 50-60 perc ent cleaner. Harbor craft emission standards were cut roughly in half. And new cargo handling equipment will be 95 percent cleaner by 2011.April 26, 2007 37 Impact of Existing Standa rds and Emission Limits

California has also drastically lowered standards for off-road sources, from lawn and garden equipment, to recreational ve hicles and boats, to construction equipment and other large off-road sour ces. From 2010 through 2014, these

new off-road sources will be manufactu red with 80-98 percent fewer emissions than their uncontrolled counterparts.

ARB has worked closely with U.S. EPA to regulate large diesel, gasoline and liquid petroleum gas equipment – where aut hority is split between California and the federal government – and by 2014, new large off-road equipment will be 98 percent cleaner. ARB has also made great strides in reducing emissions from the smaller engines under St ate control, like those used in lawn mowers and jet skis, recreational vehicles and boats. From 2010 to 2015, these new off-road

sources will be manufactured with 82-90 percent fewer emissions than their uncontrolled counterparts.April 26, 2007 38 Air Resources Board SIP C ontrol Measures (1994-2006)

activities. But because on-road and off-road mobile sources together account for so much of the State's inventory of oz one and PM2.5 forming emissions, further

reductions in mobile source emissions are essential if air quality standards are to be

realized.

Cleaning Up the Legacy Fleet

Adopted SIP measures have made significant strides in reducing emissions from those mobile sources already in use – the legacy fleet -- by keeping existing vehicles cleaner longer, getting cleaner technology on older vehicles and equipment, and replacing older dirtier vehi cles and equipment with cleaner ones. Whereas new engine emissions have been regulated for a l ong time, most of the in-use control programs have just begun to evolve and have an impact. We still have a lot of work to do to clean up the lega cy fleet. That is wh y the majority of

new measures in the State Stra tegy are in-use measures.

Many programs and rules are currently in place to reduce emissions from the mobile source legacy fleets. The Sm og Check Program ensures that passenger vehicles stay clean as they age and on-board diagnostic syst ems identify smog control problems. Heavy-duty truck inspection programs help control smoke

emissions and detect emission contro l malmaintenance and tampering.

ARB has adopted 20 in-use regulations in the last five years. In-use regulations have required use of cleaner fuels, great ly reducing emissions from ships and

harbor craft. Excessive truck and bus idling has been restricted. ARB has adopted public and private fleet rules that require local governments and private companies to incorporate the cleanest vehi cles and equipment into their fleets. In-use testing procedures and verificati on requirements for in-use emission control technology have been strengthened. And other operational and emission control technology requirements that help reduce emissions from existing vehicle and equipment have been put into place.April 26, 2007 40 Incentive programs have worked hand-in-ha nd with in-use regulations, providing

added emissions benefits. California is currently in vesting up to $140 million per year to clean up older, higher-emitting sources through the Carl Moyer Program. The Smog Check Breathe Easier Campaign pays motorists $1,000 to permanently retire their high-polluting vehicles. And local governments use special vehicle registration fees to fund projects that further reduce emissions

from motor vehicles.

Consumer Products

ARB has adopted standards to limit emissions from nearly 50 consumer product categories (such as hair sprays, deodorants, and cleaning compounds), as well as over 35 architectural coatings and aerosol paints categories. The Board has adopted and implemented voluntary provisions to offer greater compliance flex ibility to consumer product manufacturers while retaining t he air quality benefits. Without these actions, ROG emissions from these pr oducts would be roughly 60 percent greater in 2010. But, as you can see from the above chart, the impact of population growth begins to counter t he benefits of adopted measures – more

controls are needed.

Local Rules and Programs

Stationary and Area Sources

Local air districts are pr imarily responsible for controlling emissions from stationary and areawide sources, with t he exception of consumer products, through regulations and permi ts. Stationary sources include industrial sources like factories and power plants, commerc ial sources like gas stations and dry cleaners, and residential sources such as fireplaces and water heaters.

Areawide sources are diffuse sources of emissions that are spread over a wide area, such as paints and pesticides.

Local air districts help reduce emissions through limits on emissions from new sources (the New Source Review progr am) and technology-based requirements for existing sources, called Best Ava ilable Retrofit Cont rol Technology and Reasonably Available Control Technology requirements. Air districts adopt and enforce rules governing these sources of emissions.

Businesses in California are subject to t he most stringent air quality rules in the country. Local air districts have adopt ed a number of innovative rules and programs over the years to help reduce em issions. For example, South Coast’s innovative program, RECLAIM, provides ma rket incentives for companies to use the cleanest possible technologies. And the San Joaquin Valley has adopted a Without ARB Program With ARB Program Consumer Product Emissions

With ARB Pro g ramApril 26, 2007 41 first-of-its-kind indirect s ource rule that ensures that new developments bear their fair share of the pollution burden. ARB has suggested over 50 control strategies for stationary sources that many local air districts have adopted.

The proposed local air district measures for each nonattainment area are listed, described, and quantified in the attainm ent plans for each area. The local measures, coupled with the State Stra tegy measures, must provide the necessary emission reductions to meet the federal standards.

Transportation and Land Use Planning

In California, local governments are re sponsible for transportation and land use planning, and transportation plans are an im portant part of the SIP. Federal law requires a metropolitan region’s transporta tion plan to be complementary to and conform with the region’s air quality plan. Transportation and land use strategies can help to reduce the rate of growth in vehicle travel and traffic congestion, which helps reduce the growth in vehicl e emissions. All th e major metropolitan regions in California have approved plans emphasizing land use strategies that complement their transit and trans portation systems and bring more people closer to more destinations. These strategies will help curb emissions by reducing trip distances and increasing use of public transit, carpooling, walking, and biking.

ARB’s Proposed New SIP Measures

If emission reductions from the adopted m easures are not enough to attain the federal standards, sufficient emission reduc tions from new strategies must be

achieved in order to meet t he emission reduction target.

ARB staff is proposing a comprehensive and far reaching set of new measures to

achieve emission reductions needed to address California’s most challenging ozone and PM2.5 problems. These meas ures are designed to make maximum progress toward the federal 8-hour oz one standard in the South Coast and the San Joaquin Valley. The measures include aggressive near-term NOx and SOx emission reduction goals, reflecting t he nature and scope of the PM2.5 problem in these regions. To achieve the emission reductions needed for both ozone and PM2.5, the State Strat egy proposes new near-term actions that can be completed by 2010 or soon thereafter.

Focus of Proposed New Measures

Mobile sources are the largest c ontributor to PM2.5 and ozone-forming emissions. Air quality science indicate s that reductions of NOx are more

beneficial than reductions of ot her pollutant precursors to help reduce levels of both ozone and PM2.5. The simple conc lusion is that mobile source NOx reductions must be a main objective of t he State Strategy. And since the State and federal government have almost excl usive authority over mobile sourceApril 26, 2007 42 emissions, they also have the bulk of the responsibility fo r implementing the State Strategy.

Mobile sources currently produce about 90 percent of all NOx emissions in the South Coast. About 90 percent of mobile source NOx emissions are produced by five major sources – passenger v ehicles, heavy-duty diesel trucks, large off-road equipment, and two goods move ment-related sources -- ships, and locomotives. Reducing NOx emissions from these five major sources is therefore the key to meeting the objective of the State Strategy.

More than any other pollution control effo rt, ARB’s mobile source program has

moved the State’s nonattain ment areas closer to m eeting federal air quality standards. The majority of emission reductions from adopted SIP measures

comes from emission standards for new on-road and off-road mobile sources and fuels. But as new engines have become cleaner and cleaner, the emissions

contribution from older vehicles has been growing to the extent that it will soon make up the majority of mobile source emissions. For example, all on-road vehicles 14 years old or older will pr oduce almost 60 percent of total on-road NOx emissions by 2014 but just 20 percent of total miles traveled. That is why

the majority of proposed new measures in the State Strategy are in-use measures – programs to help clean up the l egacy fleet of older, dirtier vehicles and equipment. We simply can not wait for the natural turnover of older vehicles (1-5 percent annual turnover depending on vehicle or equipment type) being replaced with newer ones.

actions will center on the final increm ent needed to attain the standard in the areas with the worst ozone pollution.

Passenger Vehicles and Heavy-Duty Trucks

Despite statewide growth in vehicle travel of 35 percent over the last 15 years, total car and truck emissions (ROG+NOx) have decreased almost 50 percent.

California has led the way in adopt ing stringent regulations for passenger vehicles. Compared to uncontrolled vehicl es, cars are now 99 percent cleaner. A new 1965 car produced about 2,000 pounds of ozone-forming ROG emissions during 100,000 miles of driving. Calif ornia's low-emission standards, coupled with reformulated gasoline, have cut that to less than 50 pounds for the average new car today. By 2010, California' s standards will further reduce ROG emissions from the average new 2010 car to approximately 10 pounds.

ARB’s first diesel engine regulations went into effect in 1988. Significant gains began with the introduction of California Cl ean Diesel fuel in 1993. U.S. EPA and ARB worked together to develop and adopt the next phases of on-road diesel engine control, with cleaner fuel in 2006 and even cleaner engines in 2007 that will reduce per-truck particulate matter emissions by another 90 percent. By 2010, new trucks will be 98 percent cleaner than new pre-1988 models, providing

needed NOx reductions.

As new cars and trucks become cleaner, t he emissions contri bution from older vehicles has been growing to the extent t hat it will soon make up the majority of mobile source emissions. Thus, Californ ia’s emission control program has also had to focus on cleaning up those vehicles already in use – the “legacy” or

“in-use” fleet.

California’s Smog Check Program is t he cornerstone of the passenger vehicle in-use strategy, currently keeping over 400 tons of smog-forming gases from entering the air statewide each day. Pa ssenger vehicles are also required to NOx

ARB’s heavy-duty vehicle inspection program and periodic smoke inspection program reduce emi ssions from the legacy truck fleet. Trucks will also be requi red to have the same emission control malfunction detection software as pass enger vehicles begi nning in 2013.

Cars and heavy-duty diesel trucks currently produce about 50 perce nt of the total

NOx emissions in both the South Coast and San Joaquin Valley. By 2023, that percentage will be cut almost in half. Bu t cars and trucks still account for so

much of the State’s inv entory of ozone and PM 2.5 emissions, further reductions are essential if air quality standar ds are to be realized.

Proposed New Passenger Vehicle and Heavy-Duty Truck Measures

Passenger Vehicles

Since California’s passenger vehicle em issions standards have done their job to cut emissions to near-zero levels, the cont rol focus must shift to keeping vehicles

clean over their lifetimes. The State Strategy envisions an even stronger Smog Check program that would reduce an addi tional 40 tons per day of emissions statewide in 2014. Proposed new Sm og Check measures include annual inspections for cars with high failure rates, such as vehicles over 15 years old and vehicles accumulating high annual miles of travel, and adding inspections of motorcycles and smaller diesel vehicl es. More attention will be paid to evaporative emissions through the addition of a low-pressure evaporative test, even as exhaust emission cutpoints are tightened.

The State Strategy proposes to increas e the number of vehicles that are voluntarily retired by implementing a scr appage program for vehicles that are off cycle from their Smog Check inspections. This strategy will depend upon funding and would be targeted primarily in the S outh Coast and San Joaquin Valley. We

will also continue to ensure that the f uels used in California are the cleanestburning available, and mitigate the additi onal evaporative em issions resulting

from the addition of ethanol to gasoline.

These proposed passenger vehicle measur es would reduce total NOx and ROG emissions in the South Coast by about 32 tons per day in 2014 and over 22 tons in 2020. Likewise, this measure will r educe total NOx and ROG emissions in the San Joaquin Valley by over 10 tons in 2014 and about 7 tons in 2020.

Heavy-Duty Diesel Trucks

Substantially reducing emissions from existing trucks is key to meeting federal air quality standards, as well as achiev ing diesel risk reduction and goods movement clean air goals. The State Strategy foresees an expansive in-use diesel truck emission reduction program t hat would reduce NOx emissions by 47 tons per day in the South Coast and 61 t ons per day in the San Joaquin ValleyApril 26, 2007 45 by 2014. Direct PM2.5 emissions would also be reduced 2-3 tons per day in both the South Coast and San Joaquin Valle y during the same time period.

A comprehensive fleet modernization pr ogram beginning in 2010 would replace older trucks, repower tru cks with cleaner engines, and retr ofit trucks with devices to reduce both NOx and PM. The pr oposed modernization program would be equivalent to replacing approximately 30 percent of the oldest trucks by 2014 with 2010 model year or newer trucks, and will be accomplished through private truck fleet regulations. It is envisioned t hat the use of public incentive funds will

be needed as well to facilitate fleet m odernization on the scale necessary to

attain PM2.5 and ozone st andards within SIP deadlines.

The in-use diesel truck program also pr oposes to reduce emissions from trucks registered outside of California and to lessen the effects of emission control

deterioration.

Impact of Car and Truck SIP Measures

Adopted SIP measures would reduce passe nger vehicle NOx emissions in the South Coast by 67 percent betw een 2006 and 2020. Proposed new SIP

measures would reduce that by another 15 percent by 2020.

With New SIP Measures With Adopted SIP Measures

Good Movement Sources

The goods movement sector includes the ships, trains, port trucks, and related sources that help move materials and goods from the grower or manufacturer to the consumer. The air quality impact of the goods movement sector is a major issue in areas that host ports, large rail facilities, and major truck routes. Many entities have developed or are developing plans to address the impacts of goods movement, including the California Environmental Protection Agency and the Business, Transportation & Housing Agency, the Air Resources Board, the South Coast Air Quality Management District, seve ral California ports, and two major

railroads.

Two factors increase the importance of addressing emissions from goods movement sources. First, international trade through California’s ports is growing rapidly: the volume of goods moving th rough the Port of Los Angeles and the Port of Long Beach – the nation’s busiest port complex – is expected to more than double by 2020. Second, the most pr ominent sources in this sector have historically not been regulated as aggressi vely as stationary sources or other

mobile sources. Goods movement sour ces are also powered by diesel engines that last longer than their gasoline-pow ered counterparts, and are often rebuilt before being replaced with newer, cleaner equipment. As a result new engine standards alone will not provide emission re ductions in the timeframe allowed to

attain the federal PM2.5 and ozone standards.

New measures in the St ate Strategy focus on the following goods movement sources: ships, locomotives, harbor craf t, and port trucks. They closely mirror

the measures included in Emission Reduction Plan for Ports and Goods Movement in California, approved by AR B in April 2006, and summarized briefly in Chapter 1. It is esti mated that these measures will reduce 20 tons per day ofApril 26, 2007 47 SOx, 49 tons per day of NO x, and about 4 tons per day of direct PM2.5 in the South Coast by 2014.

Ships

Emissions from ocean-going vessels, unlik e most major pollution sources, are not projected to decrease in future years, since ships have little or no emission controls and run on high-emitting bunker f uel, and shipments of cargo containers are projected to grow significantly over the next two decades. Ships currently emit half the statewide SOx emissions, and it is estimated that ships will jump

from the sixth to the sec ond highest statewide NOx pro ducer by 2023. It is essential to reduce ship emissions as t hey are entering our ports and when they are docked through application of demons trated control technologies, use of cleaner fuels, and operational efficiencies. Since ARB does not have authority to set ship engine emission standards, we must work with national and international authorities, as well as the ports, to im plement many of the control measures.

ARB took a big step in reducing emissions from ships in December 2005 by adopting a rule phasing in the use of cleaner low-sulfur fuel in ship auxiliary engines that will reduce SOx emissions fr om auxiliary engines by 96 percent and PM2.5 emissions by 83 per cent beginning in 2010.

Proposed New Ship Measures

In addition to the 2005 auxiliary engine fuel rule, the State Strategy proposes to reduce emissions from ship auxiliary engines through cold ironing and other clean technology. Cold ironing allows ships to turn off their au xiliary engines and instead plug into an electrical system for power when they are docked at a port. This measure would phase in the number of ships capable of using cold ironing and other at-dock technologies such as the “hood”, which fits onto a ship’s

exhaust stack and cleans the emissi ons, and is estimated to reduce NOx emissions about 19 tons per day in 2014 and 28 tons per day in 2020.

The State Strategy proposes to reduce emissions from ship main engines through a variety of measures. A main engine fuel rule, patterned after the auxiliary engine fuel rule, would help reduce emissions by introducing a cleaner, low-sulfur fuel beginning no later than 2010. Increasing the use of cleaner new engines or retrofitted engines beginning in 2010 could be implemented via regulation, incentives, voluntary agr eements, or a combination of these approaches. Higher ship speeds cause mu ch higher emissions. So a measure is proposed that would strengthen a current voluntary program by requiring ships to reduce their speeds to 12 knots within 40 nautical miles of the Ports of Los Angeles and Long Beach. The combination of ship main engine measures would

reduce both NOx and SOx em issions by 20 tons per day and direct PM2.5 emissions by over 2 tons per day in 2014. These reducti ons would increase substantially through 2023.April 26, 2007 48 Impact of Ship SIP Measures

Without new SIP measures, ship NOx emissions are estimated to increase almost 90 percent between 2006 and 2020. With proposed new SIP measures, NOx emissions from ships would be 67 percent less than t he projected 2020 levels and about 35 percent less than 2006 levels.

It is estimated that SOx emissions fr om ships will double without the adopted and new SIP measures. The adopted SIP meas ure (auxiliary engine fuel rule) will help reduce SOx more than 50 percent from projected 2014 levels, but emissions would then begin increasing due to goods movement growth. With proposed new SIP measures, SOx emissions would be reduced to only 2 tons per day in the South Coast by 2014 and remain at that low level through 2020.

With Adopted ARB MeasureApril 26, 2007 49 Locomotives

Locomotives pose a difficult challenge due to their long life, interstate operations,

and California’s reliance on U.S. EPA to adopt new engine standards. A rule adopted by ARB in 2004 now requires locomotives operating in California to use cleaner, low-sulfur fuel that will reduc e SOx emissions 90 percent. Several strategies are underway to clean up locall y-based switcher engines, reduce idling emissions at railyards, and concentrate t he cleanest available line haul engines

in the South Coast. These activities are important for co mmunity health and NOx

emission reductions in the short term. But without the introduction of cleaner new locomotive engines into California operation, growth is expected to quickly catch up to these current actions and begi n to steer the NOx emissions curve upward.

In 1998, ARB reached agreement with the rail industry to accelerate introduction

of Tier 2 locomotives into the South C oast Air Basin to achieve a 67 percent reduction. However, as shown below, emissions are projected to begin increasing after 2010 due to growth. A similar agreement is needed to accelerate introduction of the next gener ation of cleaner locomotives once EPA adopts new standards.

Proposed New SIP Measures

The State Strategy proposes U.S. EPA ad option of more stringent new engine standards and a new industry commitment to accelerate introduction of cleaner engines in California to meet the atta inment needs of the South Coast and the San Joaquin Valley. It is anticipated that the new standards will reduce NOx and PM emissions by 90 percent. The propos ed measure would call for replacement of existing locomotive engines with cleaner engines and rebuilds of older engines until 100 percent of the statewide locomo tive fleet has been upgraded. ARB is pushing U.S. EPA to adopt the standards wi th earliest possible implementation, as this measure can only occur once U.S. EPA adopts new locomotive

standards.April 26, 2007 50 Impact of Locomotive SIP Measures

The proposed new SIP measures would r educe NOx emissions from locomotives by 13 tons per day in the South Coast and 16 tons per day by from 2006 to 2020.

Harbor Craft

Standards adopted by U.S. EPA provide fo r new harbor craft engines that have roughly 50 percent less NOx emissions t han uncontrolled engines. The State Strategy proposes a new measure requiri ng harbor craft owners to replace older engines with the newer, cleaner engines a nd/or add control technologies that reduce emissions, reducing NOx emissions in the South Coast about 5 tons per day by 2014.

Port trucks

Most port trucks start out as long-haul tr ucks and then are put into short-haul use as they get older and are no longer reliable enough for long-haul service. Because port trucks are purchased used, emission standards for new trucks will reduce emissions from trucks servicing t he ports later than they will impact the long-haul fleet. The State Strategy pr oposes a port truck modernization program that would phase in beginning in 2008 and would include replacing older trucks with newer, cleaner trucks and retrofitting engines with emission-reducing control technology, reducing South Coast NOx em issions 2 tons per day by 2014 and 8 tons per day by 2020.April 26, 2007 51 Large Off-Road Equipment

Emission standards for new off-road di esel engines have become increasingly more stringent over the past decade, ensur ing that new construction, mining, industrial and oil drilling equipment become progressively cleaner. By 2015, new large off-road equipment will produce 98 percent less ROG+NOx than their uncontrolled counterparts. Ho wever, large diesel off-road equipment with more than 25 horsepower remain in use for long periods of time, sometimes up to 60 years. This long life means that new, lower emitting engines are introduced into fleets relatively slowly with the result t hat the emission reducti ons and associated

health benefits from these clean er engines will also be fair ly slow to materialize.

Proposed New Large Off-R oad Equipment Measure

ARB staff is currently in the process of developing a statewide in-use off-road equipment regulation which co uld require initial NOx an d PM emissions averages to be met, with increasingl y lower emissions averages over time. Staff began work on the rule in 2004 as part of t he Diesel Risk Reduction Program. During early SIP development work in 2006, staff identified the necessity for large NOx emission reductions from off-road equipment and other diesel sources to meet the health-based federal air quality standar ds. Consequently, staff revised the control concept extensively to meet Calif ornia’s clean air needs relative to diesel particulates, ozone, and PM2.5.

This proposed measure would require owners of equipment larger than 25 horsepower to meet a stringent average emissions level across all of their equipment. The fleet average approach provides equipment owners flexibility in how they will comply, including: sw apping older, dirtier engines with newer, cleaner engines; purchasing newer equi pment (with cleaner engines); and, adding emission control devices to older engines. Equipment owners could also restrict unnecessary equipment idling.

This measure would reduce 10.5 tons per day of NOx and about 3 tons per day

of direct PM2.5 in the South Coast and nearly 4 tons per day of NOx and a ton per day of direct PM2.5 in the San Joaqui n Valley by 2014. It would also cut direct PM2.5 emissions by more than half in 2014 and by 70 percent in 2023.April 26, 2007 52 Impact of Large Off-Road Equipment SIP Measures

Adopted SIP measures would reduce lar ge off-road equipment NOx emissions in the South Coast by almost 60 perc ent between 2006 and 2020. Proposed new

SIP measures would reduce that by another 30 percent by 2020.

The State Strategy will assess an equipment modernization program once modeling for the San Joaqui n Valley’s PM2.5 SIP s hows to what extent accelerated fleet modernization may be needed.

Other Off-Road Sources

For many gasoline-fueled off-road sources, evapor ative emissions are a significant portion of total emissions. Leaky hoses, tanks, and other parts of an engine’s fuel system and refueling infras tructure release hundreds of tons of ROG into the atmosphere a day. Succe ss with low- to no-evaporative emission technology in on-road sources supports strategies to reduce evaporative

emissions to similar low levels in o ff-road sources. M any newly-regulated

sources have exhaust standards but do not yet have evaporative standards. The State Strategy proposes to set st andards where ther e are none and make standards more stringent in sources that are not adequately controlled.

Off-road sources used mainly for recr eational purposes are large emission contributors, especially during the summer ozone season. The main focus of the State Strategy on this wide array of sm aller off-road sources is evaporative emissions. Recreational marine boat engi nes and off-road recreational vehicles are the biggest targets, with standar ds being implemented by 2010 and ROG emission reductions growing through 2023 as these newer, cleaner engines become a bigger part of the overall recreat ional fleet. Refuel ing tanks, portableApril 26, 2007 53 fuel tanks, and gas stati on fueling hoses, where emi ssions are the result of evaporation or permeation of ROG from gasoline, are also targeted. The proposed measures covering these off-ro ad sources would reduce a combined 7 tons per day of ROG in the South Coast and about 4 tons per day in the San Joaquin Valley by 2014.

Areawide Sources

Consumer Products

Chemically formulated consumer products such as automotive care products, household care products, and personal ca re products have been regulated as a

source of ROG emissions in five rulema kings since 1989. As a result of these measures, statewide emissions from c onsumer products will be reduced by over 170 tons per day in 2010, a 40 percent reduction. Despite this progress, population growth in the years ahead is ex pected to reverse the downward trend of emissions from consumer products , after the latest standards become effective. Therefore, additi onal controls for this sect or will remain important. Indeed, consumer products are expected to become the largest source of ROG emissions in the South Coast, and the th ird largest source in the San Joaquin Valley by 2020.

The State Strategy will continue ARB’ s commitment to reduce ROG emissions from consumer products. Rulemakings are expected to be promulgated between 2007 and 2012, expanding beyond the cu rrent category-by-category standards and pursuing innovative approaches, reduci ng ROG emissions about 13 tons in the South Coast and almost 4 tons per day in the San J oaquin Valley by 2020.

Pesticides

Pesticide emissions from agricultura l and commercial uses fall under the Department of Pesticide Regulation’s (DPR) authority. A measure to reduce pesticide emissions was included in t he SIP adopted in 1994. Th e State Strategy includes an updated version of that measur e. It is a strategy to reduce ROG emissions from pesticides through regulatio ns that may include limitations on the use of products formulated as fumigants, registration standards requiring liquid products that contribute less to ozone fo rmation, and incentives promoting pest management practices that use less pesticide.

Local Measures

The proposed new local air district m easures, coupled with the new State Strategy measures, must provide the nec essary emission reductions to meet the

federal standards. The new local meas ures for each nonattainment area are listed, described, and quantified in t he attainment plans for each area.April 26, 2007 54 Need for Technology Development and Long-term Measures

In developing the proposed State Strategy , ARB staff analyzed whether current NOx technologies for mobile source s are clean enough to provide all the

emission reductions needed for ozone attainment in the South Coast and San Joaquin Valley. ARB included in this anal ysis the phasing in of the cleanest new technology standards from 2007-2017 t hat ARB and U.S. EPA have already adopted for diesel engines: 0.2 g/bhp-hr on-road truck standards in 2010, full offroad Tier 4 standards in 2014, and the recent U.S. EPA-proposed low-NOx standards for locomotive engines starting in 2017. The table below summarizes this analysis. For both areas, the totals of remaining emissions after full clean-up of the legacy diesel fleets are still gr eater than the NOx carrying capacities.

The clear conclusion is that even cleaner emission standards are needed than are in place today. This demonstrates t hat it necessary for the South Coast and San Joaquin Valley SIPs to rely on cl eaner – yet to be developed – technologies as allowed by federal Clean Air Act se ction 182(e)(5) for areas with the worst pollution.

* Numbers may not add exactly due to rounding

For this analysis, ARB staff assumed that in 2020 all passenger cars would be 10 years old or younger, all diesel tru cks would meet the 2010 NOx standards, all diesel construction and farm equipment w ould meet the most stringent tier 4 standards, all locomotives would meet U.S. EPA’s proposed 2017 NOx standards, and the new stationar y sources measure in the district SIPs would be fully implemented.April 26, 2007 55 The top five rows are italicized to indi cate the categories for which we assume that all vehicles and equipment meet the cleanest adopted emission standards. Included in the category “a ll other NOx sources” ar e commercial gas trucks, motorcycles, buses, motor homes, off -road recreational vehicles, and gas powered off-road equipment.

ARB staff did the analysis starting with 2020 baseline emissions since that year corresponds to the last federal attain ment deadline befor e the 2024 extremeclassification deadline under which the l ong-term measure provisions of federal law apply. The numbers woul d look nearly identical for an analysis for any year

between now and 2020 as the st arting point. (For exampl e, ARB staff calculated the “total of remaining emission” for t he San Joaquin Valley us ing a 2018 starting point. The resulting “total of remain ing emission” was approximately 195 tons per day.) The carrying capacity is indepen dent of the year. Therefore, the analysis and conclusion that it is necessary for the South Coast and San Joaquin Valley ozone SIPs to rely on cleaner , yet to be developed, technologies is general and does not change with year analyzed.

The results for the San Joaquin Valley demonstrate that the need for cleaner technologies includes cleaner technologie s for industrial sources, not just

vehicles. Close to half of the San Joaquin Valley re maining emissions, 103 tons per day compared to a carrying capacity of 160 tons per day, ar e from stationary and area-wide sources. Clearly, long-term reductions from new technologies for

both mobile and stationar y sources will be needed.

Process for Identifying Long-Term Emission Reductions

ARB has a long-standing hist ory of successfully adopt ing and implementing both technology-advancing regulations and innovative emission control techniques. By working closely with research scientis ts and the regulated industry, ARB staff have been able to craft regulations t hat are stringent enough to compel technology development, yet flexible enough to encourage industry innovations.

ARB staff believe a directed process is needed to ensure that future emission reduction opportunities are i dentified that are large enough and arrive in time to

meet the attainment deadline.

To accomplish this, ARB staff proposes to take the lead in a coordinated government, private, and public effort to establish emission goals for critical emission source categories. Each categor y’s goal will serve as a general target for how much cleaner that emission source category will need to be for attainment purposes. The setting of the source cat egory emission goals must be science-based in two ways. First, the goal s must be tied to the State’s overall emission reduction needs. Although, esti mated emission reduction needs will change as modeling and emission inventorie s are updated, a working estimate of how far technology needs to be pushed is critical to a successful outcome. Second, the goals must reflect a reasonabl e assessment of how far technology can progress over the time available for attainment.April 26, 2007 56 This process of goal setting will give dire ction and distance to ARB and air district regulatory efforts to set the next generat ion of emission standards. As ARB and air districts identify future feasible em ission reduction measures toward the goals, those measures will be incorporated into future SIPs. However, to keep nearterm focus on the need to find more emissi on reductions, ARB staff proposes to periodically brief the Board on emer ging emission reduction opportunities and promising technologies.

Potential Long-Term Concepts

Although the identification of long-te rm emission reductions will begin with the emission goal setting for critical emissi on source categories, specific approaches that ARB will evaluate for possible incl usion in the next SIP update include the following:

Passenger vehicles: look for further reductions from reduced deterioration of emission reduction components. While new cars are very clean, it may be possible to improve the on-board diagnosti c capability of passenger vehicles and heavy-duty trucks to better target sour ces of emissions and to improve and encourage higher rates of repair.

Tighten emission standards wherever possibl e: review all categories of engines

and vehicles to ensure that the cleanest co st-effective technologies are in place. For example:

• Exhaust and evaporative standards for on-road motorcycles.

• Second generation catalyst-based emission standards for inboard/stern drive marine engines.

• Tighter exhaust emission limit s for small off-road engines.

Cleaner ground support equipment: push for increased electrification. Captured vehicle and equipment fleets used at air ports are cleaner today through natural turnover and accelerated turnover spu rred through cooperative State and local government and air company efforts. However, additional opportunities for

increased electrification remain.

Air quality priority for federal transportati on funding: work with local governments to prioritize federal transportation fundi ng uses to better support air quality goals. The federal Congestion and Air Quality Improvement (CMAQ) Program annually provides to county transportation agencie s more than $200 million in the South Coast and about $50 million in the San Joaquin Valley through 2009. The purpose of the CMAQ Program, according to Federal Highway Administration 2006 guidance, is to fund trans portation projects that will contribute to attainment of national ambient air quality standards.April 26, 2007 57 Ideas Requiring Further Exploration

Air quality control is an ever emerging fiel d. At ARB, new ways to control air pollutants and improve public health are continually developed through research and other staff work. At any one time, t here are always emission reduction ideas on the horizon that we have not fully expl ored or developed. Some of these approaches that are in various stages of development could turn out to be effective strategies at some point in the future.

The following approaches show promis e as potential emission reduction strategies. However, because of te chnological constraints and uncertain authority, they are less def ined and will require significa nt exploration prior to becoming concepts.

Explore opportunities for cleaner fuels. The near-term focus for fuels-related

efforts in California will be to devel op low carbon fuels in response to the Governor’s 2007 Executive Order. Separate fr om that effort, AR B will continue to evaluate the opportunities for cost-effect ive reformulations to reduce criteria pollutant emissions.

Pursue additional emission reductions from consumer products. Despite the actions to date and the new measures propos ed in this plan, consumer products continue to be an ever larger perc entage of ROG emissions because of population growth. ARB will continue to look for even cleaner consumer product technologies and innovative approaches to reduce emissions such as reactivitybased and market-based strategies. This would continue the search for new approaches to achieve emission reducti ons initiated within the near-term consumer product measure.

Explore approaches to further reduce vo latile emissions from pesticides. With the Department of Pesticide Regulation as the lead, work with interested stakeholders to determine how pesticide emissions could be further reduced.

Continue and enhance current public education and outreach programs. Public and private energy conservation and effi ciency programs would continue and expand. The establishment of a statewide public educ ation campaign to reduce air pollution could be considered, and might include ideas to engage the public through: (1) public education that mo re clearly connects voluntary clean air actions with public health benefits, and (2) increasing awareness of available low-emitting consumer products, pai nts, vehicles, lawn equipment, and

recreational vehicles licensed to use clean air “green” labels.

Advocate for efficient regional land use and transportation strategies. In California, local governments have the aut hority over most tr ansportation funding

and land use decisions. The most effectiv e way for regions to curb long-term growth of vehicle travel and lessen aut o emissions is to build on and enhance current efforts to implement transporta tion and land use strategies proven to reduce vehicle trips and decrease average trip lengths.April 26, 2007 58 State Implementation Plan Commitments

This section sets forth the State’s SI P commitments for the 2007 State Strategy

for two of the areas that need the em ission benefits from the proposed, new

State measures to demonstrate atta inment – South Coast and San Joaquin Valley. Specific commitments for emissi on reductions as needed for attainment in other nonattainment areas, such as the Antelope Valley and Western Mojave Desert, Sacramento, and V entura County, will be devel oped later and brought for

Board consideration with SIPs for these regions.

The State’s SIP commitments co nsist of three components:

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

The total emission reductions and the obli gation to propose specific measures for

Board consideration would become enfor ceable upon approval by U.S. EPA of the State Strategy and each district’s attainment plan. The commitments for

emission reductions are calculated us ing the planning inventory described in Appendix A; progress will be tracked in the same inventory currency to assess compliance.

The total emission reductions from the new measures necessary to attain the

federal standards are an enfor ceable State commitment in the SIP. While the proposed State Strategy includes estimate s of the emission r eductions from each

of the individual new measures , it is important to note that the commitment of the State Strategy is to achieve the total em ission reductions necessary to attain the federal standards, which would be the aggregate of all existing and proposed new measures combined. Therefore, if a particular measure does not get its expected emission reductions, the State still commits to achieving the total aggregate emission reductions, whether th is is realized through additional

reductions from the new m easures, or from alternat ive control measures or incentive programs.

For informational purposes, the tables below show the expected emission reductions from the propos ed new SIP measures in the South Coast and San Joaquin Valley in 2014, 2020, and 2023. The first table shows the expected NOx and ROG emission reductions for South Coast and San Joaquin Valley for 2023, the year in which the emission reduction target must be met for the expected ozone attainment date of 2024 for these areas. The second table shows the expected NOx and ROG emissi on reductions for the two areas for 2020 to help illustrate the progress that will be made prior to the proposed 2024

attainment deadlines for the South Coas t and San Joaquin Valley. The third and fourth tables show the expected emissi ons reductions from NOx, ROG, SOx, and

direct PM2.5 in the South Coast and S an Joaquin Valley in 2014, the year in which emission reduction targets must be met for the federal PM2.5 standard.April 26, 2007 59 Expected Emission Reductions fr om Proposed New SIP Measures

TBD = To Be DeterminedApril 26, 2007 66 Commitment to Reduce Emissions via Long-Term Strategy

Consistent with section 182(e )(5) of the federal Clean Ai r Act, this SIP includes long-term commitments to achieve the la st increment of emission reductions necessary to meet attainment goals in the South Coast and San Joaquin Valley. As the State agency charged with ensuring Ca lifornia’s SIP compliance, ARB is ultimately responsible for ensuring the nec essary measures are identified no later than 2020 (three years prior to the attainment year) a nd the emission reductions achieved by 2023.

After adoption of the State Strategy, ARB st aff proposes to initiate a coordinated government, private, and public effort to establish emission goals for critical mobile and stationary emi ssion source categories. Following the setting of emission goals, ARB will st art an ongoing public process to assess technology advancement opportunities for the critical categories. ARB staff will periodically brief the Board at public meetings on em erging emission reduction opportunities, promising technologies, and the progress made in developing long-term emission

reduction measures. As ARB staff identif ies feasible technology-forcing emission reduction measures, staff will propose those measures to the Board for inclusion

into the SIP.

No later than 2020, ARB and the two air districts will prepare a revision to the 8-hour Ozone SIP that (1) reflects any modifications to the 2023 emission reduction target based on updated science, and (2) identifies any additional strategies, including the implemen ting agencies, needed to achieve the necessary emissions reductions by 2023. If the specific measures developed to satisfy the long-term obligation affect on-road motor vehicle emissions, we will work with the air districts and transpor tation planning agencies to revise the transportation conformity budgets accordingly.

South Coast: After accounting for the antic ipated benefits of both adopted and new defined State and local measures, the 2003 SIP demonstrates a need for another 281 tpd ROG and NOx reductions from long-term measures. This represents 24 percent of t he total reductions needed by 2023. We believe that this gap can be bridged through a cooperativ e effort by the local, State and federal agencies responsible for specific emission sources. This effort should focus on how to most effectively achi eve the additional reductions, considering the availability and cost of potential controls.

San Joaquin Valley: After accounting for the anticipated benefits of both adopted and new defined State and local measures, the State Strategy

demonstrates a need for another 81 t pd NOx reductions from long-term measures. This represents 13 percent of the total NOx and ROG reductions needed by 2023. We believe that this gap can be bridged through a cooperative effort by the local, State and federal agenc ies responsible for specific emission

sources. This effort should focus on how to most effectively achieve the additional reductions, considering the availa bility and cost of potential controls.April 26, 2007 67 Role of Funding and Incentive Programs

Over the past 40 years, California has st eadily improved air quality in the face of tremendous economic and population growth. T he vast majority of that progress has come from effective regulations. Accordingly, ARB st aff expects State and federal regulations to play the primary role in implementing the State Strategy. In the regulatory paradigm, polluting sour ces pay for the necessary emission controls as part of doing business. Regulated industries may pass these costs on to consumers in the form of higher prices, although competition and other factors may prevent some companies from recouping all of their control costs. Low-interest loans with extended payment periods are available to aid smaller businesses that need upfront capital to comply.

In recent years, regulatory program s have been supplemented with financial incentives to accelerate voluntary acti ons, such as replacing older equipment. Incentive programs like the Carl Moyer Pr ogram are both popular and effective. They also help to demonstrate emerging technologies that then can be used to set a tougher emissions benchmark for regul atory requirements. Most of the existing incentive programs are designed to pay for the incr emental cost between what is required by regulation and advanced technology that exceeds that level. The incentive programs are publicly funded through fees paid by California vehicle owners as part of their annual regi strations, smog inspections or new tire purchases. California is currently inve sting up to $140 million per year to clean up older, higher emission sources.

The support for clean air incentive funding from Governor Schwarzenegger, the Legislature, and California’s voting public is reflected in the passage on November 7, 2006, of the Highway Safe ty, Traffic Reduction, Air Quality, and Port Security Bond Act of 2006. The B ond Act includes $1 billion to accelerate the cleanup of air pollution caused by goods movement activities in California. With appropriation by the Legislature, and s ubject to such conditions and criteria

contained in a statute that it will enact, ARB will appropriate this money to fund

emission reductions from activities rela ted to the movement of freight along

California’s trade corridors.

Federal Actions Needed

Measures in the State Strategy to reduce emissions from interstate and international sources rely on the federal government to develop more stringent

emission standards and to ensure these st andards go into effect as soon as possible. Emission reductions from locomotives, off-road equipment, marine auxiliary engines, and harbor craft are a si gnificant part of t he State Strategy. Proposed State measures would accelerate the introduction of cleaner engines and equipment, but the emission reductions re ly on the availability of cleaner new engines.

ARB is proposing several measures to reduce ship emissions through a combination of regulations, incentives , and actions by ports and the privateApril 26, 2007 68 sector. However, national and internati onal action to clean up shipping fleets is also needed to fully realize our clean air goals. And aircraft emissions, which will

become one of the South Coast’s t op five NOx sources by 2020, are unaddressed in the State Strategy due to the lack of effective international

standards.

California must rely on U.S. EPA to r epresent its interest s before foreign or international regulatory bodies that hav e the ability to reduce emissions from international goods movement sources. In this role, U.S. EPA should advocate for the adoption of cleaner ship emissi on standards and less polluting practices by the International Maritime Organization.

Possible Federal Actions

Adopt more stringent standards for sources under federal control. U.S. EPA should move as fast as possible to lowe r standards for sources under its control, keeping in mind California’s air qua lity challenge and attainment deadlines. There are categories of emission source s that we do not have the authority to regulate at the State level. We also do not have the ability to regulate sources in

markets outside of Californi a that then operate within California. Not only would

federal action lower emissions for new sour ces, but it would allow State and local

actions to lower emissions from existi ng sources by setting in-use rules that speed up the integration of the cleaner engines and technology into California fleets. These sources include: ships, locomotives, harbor craft, aircraft, and off-road equipment and vehicles.

Federal incentives for cleaner technology. Federal funding sources for clean air projects, as well as federal tax incent ives promoting the manufacture, sale, and purchase of cleaner vehicles, equipment, and technology, could enhance California’s aggressive incentive programs.April 26, 2007 69 Ozone Attainment Demonstrations

The table on the following page illustrates how the State Strategy will meet the emission reduction targets for ozone in t he South Coast and San Joaquin Valley.

This document has presented ARB staff’s assessment of the St ate Strategy for the San Joaquin Valley and the South Coas t in detail. ARB staff has also evaluated the impact of the propos ed State Strategy on all 15 ozone

nonattainment areas. For the remaini ng areas, modeling results and air quality data analyses show that, with the conti nued reductions in emissions on track to occur in each area, all will be able to show attainment by 2021 or earlier with

identified measures.

ARB staff expects the districts withi n the Sacramento nonattainment area will request a reclassification from seri ous to severe and will need additional reductions from ARB’s proposed new measures to attain by 2019. San Diego is projected to attain by its deadline, while Ventura may consider a reclassification

to either Serious or Severe. Trans port impacted areas, es pecially downwind of the South Coast—the Antelope Valley, the Mojave Desert, and the Coachella Valley—will need to rely on new reductions that will occur upwind. We expect the local districts to request reclassi fication to get the needed time. Areas downwind of the Central Valley—Wes tern Nevada, Amador, Calaveras, Tuolumne, Mariposa, and Kern Counties—are projected to attain by their 2014 deadline with already adopted measures. Air quality modeling for these areas is new and ARB staff is continuing to evaluat e the results. Finally, three areas—the Bay Area, Butte County, and the Sutter Butt es—now attain the ozone standard.

Attainment demonstrations for these areas will be included in the individual ARB staff reports for each area.April 26, 2007 70 Setting the Ozone Emission Reduction Target (tons per day)

The Clean Air Act requires that SIPs show there will be steady progress in reducing emissions during the years l eading to the attainment date, called reasonable further progress, equal to about 3 percent per year. (Each nonattainment area’s reasonable further progress is illustrated in the local plans and in Appendix D.) Along with tracking progre ss to meet the SIP requi rements, ARB will have a stringent tracking process for strategies under its jurisdiction. There will be periodic updates to ARB’s governing board on the SIP’s New Strategies. In addition, other ARB programs vital to the SIP have thei r own deadlines and tracking schedules. The goal of ARB’s Diesel Risk Reduction Pl an is to reduce the health risk from diesel emissions 75 percent by 2010 and 85 percent by 2020. The Emission

Reduction Plan for Ports and Goods Movement in California has specific emission reduction milestones in 2010, 2015 and 2020. ARB is committed to achieving all of its goals in these plans and the SIP and will be tracking progress on each.

Contingency Measures Requirement

The federal Clean Air Act requires attain ment plans to identify “contingency measures” to be implemented if nonattain ment areas (except those designated “marginal”) fail to meet reasonable further progress requirements or to attain the federal air quality standards on time. T hese contingency measures are to take

effect without further ARB or air district action, and thus must be measures that have already been adopted when the SI P is submitted to U.S. EPA.

The bulk of emission reductions needed to attain the federal standards are achieved through the mobile source measur es in the State Strategy’s existing program. As we have noted pr eviously, California’s mobile source program has been very successful in reducing emissions in California and represents the foundation supporting attainm ent of the federal standa rds. ARB has a well established history of adopti ng and implementing mobile s ource control regulations on-time or early. As a result, we expect to achieve and even exceed reasonable further progress goals without the need for contingency measures. However, the Clean Air Act requirements necessitate that we provide c ontingency measures regardless of our expected progress in r educing emissions toward the attainment goals.

For areas designed basic, moderate, and serious, reasonable further progress can be demonstrated with already adopted measures and therefore contingency measures are not necessary. For ar eas designated severe and extreme, the emission reductions from adopted measures that go beyond the re asonable further progress requirements will constitute Calif ornia’s contingency measure commitment implemented in the unlikely event that the State does not m eet the reasonable further progress goals.

A more detailed analysis of the conti ngency measure commitment is included in Appendix D.April 26, 2007 72 

### 4. PM2.5 Attainment in the South Coast

South Coast air district modeling conduc ted in early 2007 i ndicated that the adopted and new SIP measures in the Proposed State Strategy would bring South Coast PM2.5 levels down to 15.7 ug/m 3 by 2014. While this is tremendous progress, it is still 0.7 ug/m 3 above the standard. The South Coast air district also used air quality modeling to identify additi onal reductions the di strict believes are needed beyond those in the State Strategy . The South Coast air district’s emission reduction targets and the additi onal reductions needed to meet the district’s targets are sh own in the table below.

However, the additional large NOx reductions called for by the South Coast air district is just one potential way to close the 0.7 ug/ m 3 gap. This chapter explores alternatives for attaining the federal PM2.5 standard by the 2015 deadline. It starts by characterizing t he PM2.5 problem to give context to the complexities of PM2.5 source s, formation, and control. It looks at closing the gap through aggressive direct particulate ma tter reductions: local measures to

decrease emissions from residential w ood burning, restaurant cooking, and fugitive dust. It analyzes the South Coast air district staff’s ideas for mobile

source measures to see if it is fe asible to get the additional NOx emission reductions called for by the South Coas t air district. Finally, it makes

recommendations for Board consideration regarding actions to meet the South Coast PM2.5 challenge.

Nature of PM2.5 Pollution

Assessing how emissions affect the ai r we breathe is more complicated for

PM2.5 than it is for ozone. While ozone has just two key precursors, PM2.5 is a complex mix of particles, some formed in the air and some emitted directly.

PM2.5 can be formed in the air from t he reaction of the precursor gases – primarily NOx, SOx, ROG, and ammonia. The resulting particles are referred to as secondary PM2.5. The two main components of secondary PM2.5 in the

South Coast are ammonium nitrate and ammonium sulfate, which are formed

when NOx and SOx interact wit h ammonia. PM2.5 can al so be directly emittedApril 26, 2007 73 into the air in forms such as smoke, dust, and soot. The main contributors of directly emitted PM2.5 ar e organic and elemental carbon , emitted from sources like residential wood burning, commercia l cooking, gas and diesel engines, and airborne soil (dust).

Special monitoring and analytical tool s are used to determine which sources contribute to PM2.5 levels in a specif ic area and how much. Because the PM2.5 problem can have localized as well as region al components, stra tegies that focus on the major contributors of PM2.5 in specif ic areas can be critical to meeting air quality standards.

The figure above shows the results of an AR B staff source attribution analysis of data from PM2.5 captured on filters at two monitoring sites in the South Coast: the Los Angeles-North Main (LA-North Ma in) site, located in an industrial area

1.5 miles northeast of downtown Los Angeles, and the Riverside-Rubidoux (Rubidoux) monitoring site in western Riv erside County. The analysis shows that secondary PM2.5 caused primarily by NO x and SOx emissions contributes over half of the PM2.5 pollution in both areas. This highlights the need for substantial emission reductions from mobile sources, which are the main sources of NOx and SOx. But directly emitted particles also contribute a very large portion of PM2.5 pollution. A good portion of directly emitted particles are from sources

other than motor vehicles.

PM2.5 Emission Trends – Steadily Getting Better

Emission control measures adopted to date, especially mobile source controls, have resulted in tremendous progress in r educing PM2.5 in the South Coast. Air quality data collected since initial PM2.5 monitoring began in 1990 show that between 1990 and 1998, PM2.5 annual average concentrations dropped by 30 to 40 percent throughout the air basin. PM 2.5 annual average concentrations have dropped a further 20 to 30 percent since the official regulatory monitoring program for the federal PM 2.5 standard began in 1999.April 26, 2007 74 The figure below shows that all monito rs in the South Coast Air Basin have recorded a significant decrease in annual average design values. 1 The peak annual average design value of 30 ug/m 3 in 2001, twice the level of the federal standard, dropped to 20.8 ug/m 3 in 2006. The South Coast now attains the federal 24-hour standard of 65 ug/ m 3 , further demonstrating the progress made in reducing particulate pollution in the region.

South Coast air district’s most recent modeling, released in February 2007, predicts that although we will get 95 percent of the way to the 15.0 ug/m 3 target by 2014 with adopted and proposed new SIP m easures, we will fall just short, reaching only15.7 ug/m 3 . The model’s prediction t hat PM2.5 progress will slow down, as indicated by the trend line in t he chart above, is somewhat surprising considering that emissions, specifically NOx emissions, are projected to drop by about 6 percent per year from 2006 to 2014 – about twice as fast as they fell

between 2001 and 2006.

Even more surprising were the South Coast air district modeling results indicating that it would take over 70 tons per day of additional NOx reduc tions to bridge the 0.7 ug/m 3 gap. Although measured data show a much greater response to past

emission reductions than the model shows with the future reductions, federal rules require the use of models in SIPs . If a NOx-focused approach is used to close the 0.7 ug/m 3 gap, as the South Coast distri ct advocates, much larger NOx reductions than those proposed in the State Strategy will be needed.April 26, 2007 76 Closing the Gap with Direct PM2.5 Reductions

The previous figure shows t he magnitude of the 0.7 ug/m 3 gap identified by South Coast air district modeling in rela tion to the progress we expect with the proposed State Strategy. The progress proj ected in PM2.5 levels from 2006 to 2014 is largely the result of ARB’s existi ng mobile source control program plus the new measures in the proposed State Strategy. Emissions from mobile sources of NOx and SOx, t he two key precursor polluta nts of secondary PM2.5, are projected to drop by roughly 55 percent and 75 percent, respectively,

between 2001 and 2014. Direc tly emitted particles from mobile sources are projected to drop 35 percent during this same time.

A look at the South Coast air district’s emissions inventory shows that directly

emitted PM2.5 from sources under district control are projected to increase – not decrease – by about 5 percent between now and 2014. Since the district’s modeling indicates that a ton of directly emitted particles has a greater impact on

PM2.5 levels than a ton of NOx emissions , the District should explore additional

measures to reduce emissions from these sources as a way to cut PM2.5 levels and close the 0.7 ug/m 3 gap.

South Coast PM2.5 Source Contributions

Numerous source apporti onment studies have been conducted in the South Coast reflecting snapshots of different sites and time. While the precise contribution varies, these studies have a ll identified diesel and gasoline vehicle exhaust, smoke from wood burning and cook ing, and fugitive dust as important contributors to measured particulate matte r concentrations. For this SIP, ARB staff conducted new source apporti onment analysis (Positive Matrix Factorization) using monitoring data from 2003 through 2005 at Los Angeles and Riverside. This analysis, in conjuncti on with the results fr om past studies and

assessment of the current emissions inv entory, served as a screening tool to identify potential sources of primary PM2.5 that could provide opportunities for

further control.

ARB staff analyzed data from the LA-Nor th Main and Rubidoux monitoring sites using the Positive Matrix Factorizati on (PMF) analysis method to identify the sources that contributed to PM2.5 captured on filters at those sites. The results of this analysis, illustrated in the pie charts below, indicate that sources of directly emitted particles are significant contribut ors to PM2.5 concentrations. Two key categories are smoke and air borne soil, which each contribute 6-10 percent to observed annual average concentrations in Los Angeles and Riverside. The smoke category reflects contributions fr om residential wood burning as well as managed and wildland fires; smoke from co mmercial cooking is also in this category. The airborne soil category refl ects dust kicked up by vehicles traveling on paved and unpaved roads, and dust from construction and agricultural

activities.April 26, 2007 77 ARB staff solicited peer review of the recent source appor tionment modeling,

which concurred that the source contribut ion estimates were in the ballpark of expected values and suggested improvements for several technical aspects of the source apportionment modeli ng. Therefore, the body of evidence continues to suggest the significance of sources such as wood burning, cooking, and fugitive dust as opportunities for further targeted control efforts.

Due to the significant population growth in the basin, emissions from residential wood burning, commercial cooking and fugiti ve dust will continue to increase.

Stricter controls are needed to miti gate the emissions growth and provide

emission reductions needed for PM2.5 atta inment by the 2015 deadline.

Measures for Residential Wood Burning

ARB staff estimates that wood smoke contributes about 1.5 ug/m 3 to measured annual average PM2.5 levels at Rubi doux, based on staff’s PMF source attribution analysis. Wood smoke conc entrations are higher during the winter

months of November th rough February, when resident ial wood burning is the most likely source. The analysis also s hows that wood smoke levels are higher on weekends and holidays, indicating that much of this residential wood burning

s done for ambience and not for home heati ng purposes. Because the source attribution analysis suggested that re sidential wood burning was likely a significant part of PM2.5, ARB staff next used the South Coast air district’s air quality model to evaluate the potential for reductions.

Residential wood burning rules are feasible. A number of air districts in the State have already adopted comprehensive re sidential wood burning programs, including the San Joaquin Valley and Great Basin Valley air districts. An important component of these resident ial wood burning programs is the mandatory curtailment of the use of fireplaces and woodstoves on days with expected high levels of particulate matter. These programs, particularly the San Joaquin Valley’s, demonstrate both their fe asibility and their cost-effectiveness. Aug. 2003 - Dec. 2005 Average Source

Therefore, a phased approach in the South Coast has the best chance of success. For example, the program coul d begin as a voluntary program with an aggressive public education and information campaign. This could be followed by a mandatory program to restrict re sidential burning on selected days from November through February ( with exemptions where no al ternative heat source or natural gas service is available). Ov er the course of t he program, analysis of measured air quality data would show its effectiveness and allow the district to optimize the program to get the needed reductions by 2014.

ARB staff analyzed the impact of a full moratorium on residential wood burning from November through February using the South Coast district’s air quality model. The air quality modeling analys is showed that annual average PM2.5 levels at Rubidoux would drop by 0.9 ug/m 3 with a full moratorium between November and February. ARB staff also did a separate source attribution data analysis to assess the potential impact of a wood burning moratorium. The data analysis corroborated the modeling analysis.

Although assuming a moratorium would be 1 00 percent effective is not realistic, the potential reductions from a complete moratorium are greater than needed to close the 0.7 ug/m 3 gap. A residential wood burni ng program would only need to be 80 percent effective to fully close the 0.7 ug/m 3 attainment gap (0.9 ug/m 3 X 0.80 = 0.72 ug/m 3 .)

The South Coast air district is curr ently developing a residential wood burning program, but the staff’s most recent draft rule falls short of what is needed for

PM2.5 attainment. The South Coast should include a comprehensive suite of requirements in the rule to both minimi ze the current level of burning, and to prevent further growth in this category. Feasible measures in rules adopted by

other California air districts include a mandatory curtailment program, limits on the installation of wood burning devices in new homes and commercial facilities, and the required replacement of non-EPA compliant w ood burning stoves.

If measured air quality in 2014 indicates the need, a temporary moratorium in residential wood burning could be implem ented. The South Coast’s modeling projects that the measures identified in ARB staff’s proposed State St rategy will reduce NOx emissions sufficiently to bring the Air Basin into attainment by about 2017, indicating that the distri ct would at some time have the option of lifting the most stringent elements of its localized controls for directly emitted PM2.5.

Enhance Control of Smoke from Commercial Cooking

As discussed previously, some of the sm oke particles in the air come from restaurant cooking. By looking at the seasonal profile of t he wood smoke levels as well as weekend versus weekday patte rns, ARB staff estimated that cooking operations could comprise about one third of the wood combustion contributionApril 26, 2007 79 and therefore contribute approximately 0.5 ug/m 3 to annual average PM2.5 at

Rubidoux.

The South Coast currently has a rule t hat applies to chain-driven charbroilers. However, a 1997South Coast survey found t hat only four perc ent of restaurant cooking operations operat e chain-driven broilers, with the rest operating underfire broilers, griddles, or deep fat fryers . The Bay Area air district is in the process of developing a new rule that would require the installation of highefficiency filters on all types of cooking operations.

Therefore, as a further means to reduce direct PM 2.5 emissions, the South Coast air district could potentially strengt hen its rule along the lines the Bay Area air district is exploring. This would requi re the installation of high-efficiency filters in both existing and new restaurants fo r under-fried broilers, griddles, and deep fat fryers, in addition to the existing provisions for chain-driven broilers. If a strengthened rule could get 20 percent reductions from these currently uncontrolled sources, it could reduce Rubidoux PM2.5 levels by another 0.1 ug/m 3

.

Strengthen Fugitive Dust Control

Airborne soil is a third category of dire ctly emitted PM2.5 that can provide an additional opportunity for further emi ssion reductions. The estimated annual average contribution from ai rborne soil at Rubidoux is approximately 1.6 ug/m 3

. Sources of this soil include dust that is generated from travel on paved and unpaved roads, construction and agricultural activities, and dust that is kicked up by high winds.

The South Coast has a comprehensive fugitive dust rule to reduce emissions

from these activities. R equired mitigation measures in clude application of water or other chemical stabilizers, paving and la ndscaping, minimizati on of dust trackout, and street-sweeping. However, t he South Coast air district has adopted

more focused dust controls for the Coachella Valley. Applying the focused Coachella Valley dust rules basin-wi de may provide additional reductions. Likewise, increased fugitive dust enforce ment activities or other targeted measures could be implemented to furt her reduce this source of PM2.5.

Estimated Impact of Local Direct PM2.5 Measures

These measures – resident ial wood burning, commercia l cooking, and dust -- are reasonable, feasible, and cost-effec tive. The recommended temporary mandatory wood burning curtailm ent could be implemented with minor direct cost to the public. Other air districts ha ve already adopted or are pursuing rules implementing these measures. Of cour se, given the magni tude of the South Coast PM2.5 challenge, the South C oast air district may need to do more.April 26, 2007 80 Using both modeling and PMF analysis, ARB staff quantif ied potential benefits of the measures. The figure below illustrat es how these measures could close the 0.7 ug/m 3 gap to reach attainment by 2015.

Source Measures

As part of its draft plan, the South Coast AQMD has proposed several measures for reducing emissions from on-road and off -road mobile sources that the district

staff believes will achieve 70+ additional tons per day of NOx reductions – the

additional NOx reductions that the South Coast modeling indicates are needed to

meet the PM2.5 standard. ARB staff have reviewed and assessed the proposed

measures.

The State Strategy is es timated to achieve 322 tons per day of

NOx reductions from alr eady-adopted measures and 122 tons per day of NOx reductions from proposed new measures in the South Coast Air Basin by 2014. The State Strategy includes proposed me asures to turn over and clean up the existing fleet of diesel vehicles and equipment at a scale that far exceeds anything attempted in the r egulatory landscape to date.

The South Coast air district staff’s proposal looks to reduce 71 additional tons per day of NOx through public funding assist ance that would be used to increase the rate of turnover and clean up of the l egacy fleet beyond t hat of the State Strategy. It estimates the public fundi ng need at $600 million per year from 2009 through 2014, for a total of $3 billion.

ARB staff agrees with the South Coast ai r district staff’s assessment that the district’s suggested measures will cost b illions of dollars, but ARB staff believes that only about 50 percent of the reductions, at most, are technically feasible even if subsidized. ARB staff believes that the turnover necessary to get reductions of this magnitude in this s hort time frame would not be possible. Furthermore, the funding for the scale of the measures envis ioned by the South Coast air district staff is not currently available, so the measures cannot be included as approvable m easures in the SIP.

The following is a brief assessment of eac h of South Coast air district staff’s proposed measures:

Accelerated Penetration of ATPZEVs (SCONRD-01)

Measure summary: This measure proposes that ARB use a combination of mandates and incentives to increase sales of advanced technology partial zero emission vehicles (ATPZEVs) that have an all-el ectric drive range (i.e. plug-in hybrid vehicles) to 100,000 vehicles in the South Coast by 2014, and 1,000,000 vehicles by in the South Coast by 2020. The district es timated reductions of 1.0 tpd NOx and 0.5 tpd VOC in 2014. The AQMD did not conduct a cost-effectiveness analysis.

ARB staff assessment: Availability of an almost all-electric drive range ATPZEV is unrealistic based on available technology. Most optimistic pr ojections indicate that 10,000 plug-in hybrids with a 10 mile drive range could be on the road in California by 2014 if

three to four automobile manufacturers co mmit to producing them. The cost of plug-in hybrid vehicles could be appr oximately $2,000-5,000 more than hybrid vehicles on the market today. The uncer tainty surrounding plug-in hybrids stems from the higher cost of larger batteries and commitment from automobile manufacturers to produce these vehicles.April 26, 2007 83 Conversion of current ATPZEVs to plug-in hybrids is technologically possible, but

not feasible on this scale under t he South Coast proposed timeframe. Conversion packs used to enhance current hybrid technology have not been

certified to meet safe ty or emission standards.

OBD III for Light and Mediu m-Duty Vehicles (SCONRD-02)

Measure summary: This measure would require a higher le vel of on-board diagnosti cs (OBD III) on all new vehicles starting in 2012, and wo uld require that existing 1996-2012 vehicles be retrofitted with OBD III by 2020. It would achiev e about 0.5 tpd NOx in 2014 at a total retrofit cost of $746 million, plus additional costs for new

vehicles built in 2013 and later.

ARB staff assessment: State law (Health & Safety Code section 43600) prohibits ARB from requiring the

installation of control devices on used mo tor vehicles except when required or authorized by statute. Statutes enacted since have given ARB authority to require retrofit controls on heavy-duty vehicles. But no such statute has been enacted for light-duty vehicles, so ARB’s authority to mandate th e installation of OBD retrofit kits on used light-duty vehicl es is unclear. Consumer acceptance is

also an issue.

Further Emission Reductions from On -Road Heavy-Duty Vehicles (SCONRD-03)

Measure summary: This proposed measure calls for the reduction of 21 to ns per day of NOx in 2014 beyond the State Strategy’s proposed fleet modernization measure. The State Strategy’s proposed measure would achiev e reductions equivalent to replacing 30 percent of the heavy-duty fleet by 2014. The district’s proposal would retrofit or replace an additional pre-2010 or trucks at the rate of 15 percent per year above the proposed ARB program..

ARB staff assessment: To achieve the 21 tons per day of NOx reduction estimated, ARB staff estimated that more trucks would need to be replaced or retrofited in the 2011-2014 timeframe than suggested in the district’s proposal, and that NOx retrofit efficiencies would need to be signific antly higher than today’s technology. Currently, only one low-NOx catalyst device is verified for a 30 percent NOx reduction, and no devices are verified fo r on-road use that have a higher NOx removal efficiency.

Using South Coast’s proposed strategy, AR B staff has estimated a 12 tons per day NOx reduction at an estimated cost of $812 million. This strategy could be implemented using available technology; however, it would add almost $1 billion to the cost of the very aggressive fleet modernization proposed by ARB.April 26, 2007 84 Further Emission Reductions from Hea vy-Duty Trucks provid ing Freight Drayage Services (SCONRD-04)

Measure summary: This proposed measure would retrofit and replace port tru cks so that much of the port truck fleet would meet 2007-2010 st andards by 2012, and the remainder would be equipped with PM and NOx retrofit devices. The district’s proposal would achieve approximately an additional 6 tons per day NOx reduction in 2014 for an investment of over $1.8 billion. About half the replacement engines would

use alternative fuels.

ARB staff assessment: The technology for this proposed measure should be available; however, it is unknown how many alternative fuel engines will be certified to the 2007 and 2010 standards. This measure is dependent on securing sufficient incentive funding and is only feasible if subsidized.

Construction/Industrial Equipment Fl eet Modernization (SCOFFRD-01)

Measure summary: This measure proposes to reduce an addi tional 16 tons per day of NOx in 2014 from large off-road equipment by achieving a 2018 fleet average in 2014 (equivalent of ~Tier 3) with emission reductions equivalent to repowering all Tier 0 and Tier 1 equipment with Tier 3 or better engines (i.e., 2010 on-road engines). In 2020, the m easure proposes to get r eductions equivalent to repowering all Tier 2 equipment with Tier 4 or better engines and retrofitting all Tier 3 engines with selective catalytic reduction (SCR).

ARB staff assessment: It is not technologically feasible to repow er all Tier 0 and Tier 1 equipment with Tier 3 engines due to space constraints and other considerations. Repowers with Tier 4 engines will be even more challengi ng, if possible at all. Because of these technological constr aints, a significant porti on of the off-road equipment would have to be replaced to achieve the projected reductions. Equipment replacement is more expensive than repowering, and w ould substantially

increase the cost of this measure and the magnitude of subsidies needed.

This measure is feasible only if subsid ized. The increased costs of replacing equipment makes the propos ed measure much less feasible from a costeffectiveness standpoint.

Further Reductions from Cargo Handling Equipment (SCOFFRD-02)

Measure summary: This measure would require the repoweri ng of non-yard trucks (i.e., container cranes and loaders, front- end loaders, bulldozers, etc.) with Tier-4 offroad engines or the retrofitting of these engines with SCR. This measure is designedApril 26, 2007 85 to be phased in and to reduce NOx emissions from such equipment by 30%, and a total of 1 ton per day of NOx, by 2014.

ARB staff assessment: The repowering of non-yard trucks with Ti er-4 engines will be difficult due to the larger engine compartments required for these advanced emission control power systems in comparison to in-use engine compartments. As a result, many vehicles would probably be retrofitted with SCR systems in order to comply. While there are no technological barriers to SCR retrofits on these vehicles, the

cost of these modifications will increase the capital investm ent requirements for terminal operators. Lease provisions r equiring the same improvements will allow terminal operators to be eligible for subsid ies from the Ports of Los Angeles and Long Beach.

Further Reductions from Locomotives (SCOFFRD-03)

Measure summary: This measure recommends retrofitting rema ining Tier 2 locomotive engines with DPF and SCR technology to achieve Tier 4 emission levels, which the district projects would reduce NOx em issions by an additional 11 tons per day of NOx in

2014.

ARB staff assessment: The State Strategy proposes an aggressive penetration rate to introduce Tier 4 engines and retrofits for Tier 2 engines that depends on U.S. EPA adopting strict standards that go into effect before 2014. (U.S. EPA has proposed standards for new engines that go into effect by 2017; however, ARB staff continues to make

the case that California needs earlier implementation.) The retrofit technology needed to bring locomotives up to Ti er 4 standards has not been tested on locomotives as large as the long-haul locomotives used in the U.S. The availability of proven and te sted technology at the scale envisioned is unsure. Since there is uncertainty about the in troduction of the new standards prior to 2014, staff believes that t he 4 tons per day of NOx emission reductions from locomotives in the South Coast proposed in the State Strategy is the maximum commitment that should be made by the Board given the federal preemption.

Emission Reductions from Airport Gr ound Support Equipment (SCOFFRD-04)

Measure summary: This measure proposes to reduce NOx emissions from ground support equipment by an additional 0.8 tons per day in 2014 through increased

electrification and a lo wer fleet average.

ARB staff assessment: A Stipulated Agreement settling litigat ion between the owners of Los Angeles International Airport (LAX) and neighbor ing cities over environmental impacts resulting from airport exp ansion requires LAX to impl ement a phased program to convert all ground support equipment to “extremely low emission technologyApril 26, 2007 86 (such as electric power, fuel cells, or other future technological developments)” by 2015. This agreement will cover 70 per cent of all ground support equipment in the air basin. If subsidized, this proposed measure could possibly achieve 0.2 tons per day of NOx from the remaini ng ground support equipm ent at the other airports in the air basin.

Further Emissions Reductions from Trans port Refrigeration Units (SCOFFRD-05)

Measure summary: This measure proposes to retrofit in-use transport refrigerat ion units (TRUs) with SCR systems to reduce NOx emissions by 80 percent, reducing NOx by 1.1 additional tons per day by 2014.

ARB staff assessment:

This measure has not been demonstrated to be technologically feasible due to the lack of SCR system testing on engi nes as small as those powering TRU systems. SCR is most effe ctive when used in systems t hat can maintain a high, constant exhaust temperature to suppor t the reaction that occurs on the catalyst’s surfaces. In general, SCR is not viable for engines of less than 150 horsepower as they do not usually reach or maintain the needed exhaust temperatures.

Accelerated Turnover and Catalyst Based Standards for Pleasure Craft (SCOFFRD-06)

Measure summary: This proposed measure calls for provid ing $52 million in incentives in 2014 for Southern Californians to purchase new recreational boats and jet skis sooner than they would have without t he incentives. It is estimated to achieve 1 ton per day of additional NOx reductions in 2014.

ARB staff assessment: While technically feasible if subsidized, it is not practical to assume that 50,000 recreational boats and jet skis could be replac ed in a very short period of time. No pilot projects have been conducted to test the feasibilit y and/or success of incentive-based replacement programs for pleasure craft.

Further Emission Reductions fr om Gasoline Fuels (SCFUEL-01)

Measure summary: This measure calls for ARB to adopt a sulfur content limit of 10 ppm for future gasoline fuels, reducing NOx an es timated 5 tons per day by 2014.

ARB staff assessment: This measure is not necessary. The South Coast air district analyzed the potential emissions reductions using the sulfur cap limits specified in the California reformulated gasoline (CaRFG) regulations. However, while the cap limit for sulfur is 30 parts per million by weight (ppmw), the av erage sulfur contentApril 26, 2007 87 in gasoline marketed in California is 10ppmw. The emission benefits from this low sulfur gasoline have been used to allo w other CaRFG limits to increase while minimizing costs and maximizing production.

The Board is tentatively scheduled to consider amendments to the CaRFG regulation in June that would offset t he increase in hydrocarbon evaporative permeation emissions resulting from the use of ethanol. The only practical path to offset this increase in hydrocarbon emissions is to use more ethanol, going from an average of 5.7% to 10% ethanol content. While this decreases hydrocarbon emissions, it increases emissions of NOx. , Refiners are expected

to decrease sulfur levels even further to avoid this NOx increase, and as a result future CaRFG-compliant gasolines are expected to have an average of 5 to 7ppmw sulfur. This is approx imately the sulfur content that refiners would aim for to ensure continued compliance with a 10ppmw cap. This mean s that there are no emission benefits to be gained fr om adopting a 10ppm w sulfur limit.

Further Emission Reductions from Diesel Fuels (SCFUEL-02)

Measure summary: This measure calls for ARB to adopt new regulations requiring the use of diesel fuel alternatives to replace 10 percent of conventional diesel fuel, reducing NOx emissions by an additional 4 tons per day by 2014.

ARB staff assessment: South Coast staff expects the largest portion of the diesel fuel alternatives to be met through the use of gas to liquid (GTL) diesel, which has zero sulfur. They project that GTL diesel will cost 15 c ents more per gallon than conventional

diesel. ARB staff believes that the Sout h Coast staff estimated cost for the GTL is low by a factor of 2 to 5. The co st to produce GTL is about $0.15 per gallon higer than the cost production cost of dies el, but this is based on the natural gas feedstock being virtually free. The cost of transporting the fuel to California, would add approximately another $0.15 per gallon. In a ddition, California would have to compete with the rest of the world to obtain GTL diesel, which means we would have to pay an “incentive cost” – we would have to pay more than other countries that also prize GTL for its ability to improve the overall quality of diesel. These factors make the proposed measur e not feasible due to total cost and

emission reduction cost-effectiveness.April 26, 2007 88 How to Advance South Coast PM2.5 A ttainment – Recommendations for

Board Consideration

ARB staff has assessed the PM2.5 challenge in the South Coast starting with the premise that, as shown by South Coast ai r district modeling, additional measures

are needed to reduce PM2. 5 levels by 0.7 ug/m 3 . ARB staff has concluded the following:

• Given the PM2.5 progress measured ov er the last 15 years, and the new emission reductions that will occur, the South Coast may attain the standard by 2015 with the mobile source measures in the proposed State Strategy. Nevertheless, U.S. EPA requires the use of models in SIPs to demonstrate attainment; therefore, addi tional emission reductions should

be identified.

• The large new NOx and SO x reductions from mobile sources identified in the proposed State Strategy will provide the vast ma jority of the emission reductions that will occur by 2015.

• Reversing the trend of rising PM2. 5 emissions from sources under air district control through aggressive lo cal measures to reduce directly

emitted PM2.5 is critical to attainment.

• Closing the 0.7 ug/m 3 attainment gap by 201 5 with additional NOx

reductions is not realistic. The Sout h Coast air district’s suggested mobile

source measures are not feasible without billions of dollars of unsecured

subsidies.

• Feasible local air district meas ures for residential wood burning, commercial cooking, and dust exist to close the 0.7 ug/m 3 gap and reach attainment by 2015.April 26, 2007 89 

### 5. PROPOSED NEW SIP MEASURES – Descriptions

Introduction

ARB staff is proposing a comprehensive and far reaching set of new measures to

achieve emission reductions needed to address California’s most challenging ozone and PM2.5 problems. These meas ures are designed to make maximum progress toward the federal 8-hour oz one standard in the South Coast and the San Joaquin Valley. The measures include aggressive near-term NOx and SOx emission reduction goals, reflecting t he nature and scope of the PM2.5 problem in these regions. To achieve the emission reductions needed for both ozone and PM2.5, the State Strat egy proposes new near-term actions that can be completed by 2010 or soon thereafter.

Need for Fleet Modernization

More than any other air pollution control effort, ARB’s mobile source program has

moved the State’s nonattain ment areas closer to m eeting federal air quality

standards. California has dramatically tightened emi ssion standards for new onroad and off-road mobile sources and f uels. As new engines have become cleaner and cleaner, the emissions contri bution from older vehicles has been growing to the extent that it will soon ma ke up the majority of mobile source emissions. For example, by 2014, heavy-duty trucks 14 years or older will produce 51 percent of tota l heavy-duty truck NOx emissi ons while only traveling 20 percent of total truck miles. The same holds true for all on-road vehicles combined, where vehicles over 14 year s old will produce almost 60 percent of total NOx emissions by 2014 but just 20 percent of total miles traveled.

The benefits of in-use control program s are limited by the underlying engine technology and controls. As a result, the majority of new measures in the State Strategy are “in-use” m easures – programs to help clean up or replace older, dirtier vehicles and equipment. We simply cannot wait for the natural turnover of older vehicles and equipment (1-5 per cent annual turnover depending on vehicle or equipment type) being replaced with new er, cleaner vehicles. The challenge

is that these measures have a much more direct impact on businesses and individuals in California than do new engine standards that must be met by

manufacturers. ARB’s fleet rules will affe ct owners of public and private vehicles and equipment that operate in nonattainme nt areas throughout the State.

Compliance flexibility has historically been included in ARB r egulations – allowing

the most cost-effective methods to be used by those who must meet emission requirements. And while lower-cost add-on control devices can play a role in lowering emissions from mobile fl eets, more costly engine and vehicle replacements will be needed in many cases. This will place a substantial

financial burden on owners of vehicles and equipment but is necessary in order to achieve air quality standards. Incr eased incentive funds can supplement ARB’s regulatory actions and further acce lerate air quality progress. It is important to recognize that at current funding levels, incentive funds can pay forApril 26, 2007 90 only a relatively small portion of the cost for necessary modernization of California’s diesel engine fleets.

The nature of the proposed new measures (enforceabl e rules) and California’s history of supportive financial incentives provide a sound basis for reductions from incentive programs to meet f ederal requirements for SIP approval.

Accountability for Emission Reductions

California’s SIP must outline the plan for me eting air quality standards in all of its

nonattainment areas. ARB staff’s SIP State Strategy proposal for Board approval includes an enforceable commitment to achieve the overall goals set. The details of each new measure are public ly considered during separate formal rulemaking processes. If a particular measure does not ultimately achieve the emission reductions estimated in the SIP, the State is still bound to achieve the total aggregate emission reduction commitmen t, whether this is realized through

additional reductions from other new m easures, or from al ternative control measures or incentive programs.

Summary of Proposed New SIP Measures

ON-ROAD SOURCES

Passenger Vehicles

Improvements and Enhancements to California’s Smog Check Program

Low Pressure Evaporative Test. Require low pressure evaporative system testing and repair of evaporative system leaks for all vehicles subject to Smog Check inspection.

More Stringent Cutpoints. Set more stringent pass/fail cutpoints to ensure more cars would have more comp lete and durable repairs.

Annual Inspections for Older Vehicles . Inspect older vehicles annually rather than every two years. Ol der vehicles tend to have greater

deterioration of emission controls , and consequently, higher emissions.

Annual Inspections for High Annual Mileage Vehicles. Inspect annually, rather than every two years, vehicles that accrue very high mileage on an annual basis. High mileage vehicles t end to have greater deterioration of emission controls and, consequently, higher emissions.

Add Visible Smoke Test . As part of the Smog Check test, include a check for visible smoke to identify vehi cles with excess particulate matter

emissions.April 26, 2007 91 Inspection of Light- and Medium-Duty Diesels. Include light- and medium-duty diesel vehicles in t he Smog Check program to provide for improved maintenance and reduced emissions for this part of the fleet, and require the repair of poorly mainta ined or old emission systems.

Inspection of Motorcycles. Include motorcycle inspections as part of Smog Check. Studies indicate that motorcycl es are subject to high rates of exhaust system tampering.

Expanded Passenger Vehicle Retirement. Increase the number of vehicles that are voluntarily retired by implement ing a scrappage program for vehicles that are off-cycle from their Smog Check inspections.

Modifications to Reformulated Gasoline Program. Modify California’s Reformulated Gasoline Program to offs et ROG emissions due to the increased use of ethanol. This rulemaking activity is currently underway and is intended to fully mitigate the emission increase, wh ich has been incorporated in the current emissions inventory.

Trucks

Cleaner In-Use Heavy-Duty Trucks. This proposed measure is a comprehensive in-use diesel truck emi ssions reduction program that includes a

fleet modernization rule and an excess emis sions program. Fleet modernization would focus on overcoming the typically slow rate of heavy-duty truck turnover by requiring truck owners to meet specifi ed emission levels through replacing or cleaning up the oldest trucks in their fleet s, and would also include a program for

out-of-state trucks. The excess emissi ons program would target deterioration emissions to keep ultra-clean trucks running cleaner longer.

GOODS MOVEMENT SOURCES

Ship Auxiliary Engine Cold Ironing and Other Clean Technology. Reduce emissions from ships at berth with at- dock technologies such as cold ironing (electrical power) and other clean technologies.

Cleaner Ship Main Engines and Fuel. Further reduce emissions from main engines through added retrofits such as selective catalytic reduction. Support efforts by ports and appropriate local entit ies to accelerate use of cleaner ships and rebuilt engines through other tools such as lease restrictions. Require ships

to use low sulfur diesel fuel in main engines when operating within 24 nautical

miles of shore.

Port Truck Modernization. Retrofit or replace ol der heavy-duty diesel trucks that service ports. Work wit h port authorities to prevent adding older trucks to the fleet. ARB rulemaking proc ess for this proposed measure has begun in parallel with development proposals by the Po rts of Los Angles and Long Beach.April 26, 2007 92 Accelerated Introduction of Cleaner Line-Haul Locomotives. Replace existing locomotive engines with cleaner Tier 4 engines beginning in 2012 and

conduct concurrent rebuilds of older engines to Tier 2.5 standards. This measure requires early introduction of U.S. EPA Tier 4 standards.

Clean Up Existing Commercial Harbor Craft . Require owners of existing commercial harbor craft to replace old engines (both propul sion and auxiliary) with newer cleaner engines and/or add emi ssion control technologies that clean up engine exhaust. ARB rulemaking for this proposed measure is underway.

OFF-ROAD SOURCES

Construction and Other Equipment

Cleaner In-Use Off-Road Equipment. Establish fleet average emission limits for off-road equipment (over 25 horsepowe r) that would require older, dirtier engines to be replaced with engines reflecti ng current technologies or retrofitted

with emission control devices. ARB rule making for this proposed measure is in

process.

Agricultural Equipment

Agricultural Equipmen t Fleet Modernization. Accelerate the modernization of the fleet of agricultural equipment used in California, removing older, dirtier equipment from service to be replac ed with engines reflecting cleaner technologies.

Evaporative and Exhaust Strategies

New Emission Standards for Recreational Boats. Adopt catalyst-based standards (5 g/kW-hr) for new outboard and personal water craft (jet ski) engines and evaporative emission standards to addre ss all sources of recreational boat evaporative emissions.

Off-Road Recreational Vehicle Expanded Emission Standards. Adopt exhaust and evaporative emission standards to reduce the amount of ROG from off-highway motorcycles and all-terrain vehicles.

Additional Evaporative Standards Portable Outboard Marine Tank Evaporative Standards. Set evaporative standards for removable fuel tanks used

on outboard recreational boats. Refueling Gasoline Tank Evaporative

Standards. Set evaporative standards for ref ueling gasoline tanks typically mounted on pickups and large recreati onal vehicles and used to refuel equipment and other smaller vehicles. Gas Station Refueli ng Hose Evaporative

Standards. Set evaporative standards for gas station pump hoses.April 26, 2007 93 Enhanced Vapor Recovery for Above Ground Storage Tanks . Implement an enhanced vapor recovery certification process and new performance standards and specifications for large fuel tanks us ed extensively in agricultural operations.

AREAWIDE SOURCES

Consumer Products

Tighten Standards. Tighten standards or require product reformulation for consumer products categories thr ough several rulemakings through 2012.

Pesticides

New Pesticide Strategies. The California Department of Pesticide Regulation will reduce emissions from commercial and agr icultural pesticide use in California through reformulation, reduced usage, and innovative technologies and practices.April 26, 2007 94 Improvements and Enhancements to California’s Smog Check Program

California’s passenger vehicle emissions standards have been extremely effective -- a new 2005 car was 97 perc ent cleaner than a new 1980 car. In order to reduce the emissions necessary to reach air quality goals, however, the focus must shift to keeping vehicles cl ean over their lifetim es. The Smog Check program is the cor nerstone of this effort, keeping over 400 tons of smog-forming emissions from entering the air each day.

The State Strategy envisions an even stronger Smog Check program, adding

tests that will reduce excess emissions and including vehicle types that are now exempt to better ensure that all passenger vehicles in California keep running clean. Staff has estimated that adding the following tests to Smog Check will reduce ROG and NOx emissions from passe nger vehicles another 10 percent in 2014. This equates to reducing about 11 tons per day of ROG and 12 tons per day of NOx in the South Coast in 2014.

Low Pressure Evaporative Test Over half of smog-forming emissions fr om 1976 through 1995 cars comes from fuel evaporating from leaks in the fuel system. A functional check of the gas cap is currently included in Sm og Check, but not a check of the vehicle’s fuel tank and vapor lines, which play an import ant part in controlling evaporative

emissions. This measure would add a lo w pressure evaporative test to Smog

Check to examine for leaks in the fuel tank and vapor lines.

More Stringent Cutpoints One approach to getting more complete repairs and lower emissions is to increase the stringency of the inspection st andards (cutpoints) used to determine if the vehicle initially passes or fails. This measure woul d set more stringent cutpoints, ensuring that more cars would have more complete and durable repairs.

Annual Inspections for Older Vehicles Vehicles 15 years or older have a failure rate more than twice the average. This measure would require older vehicles to be tested annually, shortening the time they are emitting excess emissi ons prior to being repaired.

Annual Inspections for High Annual Mileage Vehicles About 3 percent of cars are driven over 25,000 miles per year. These vehicles fail Smog Check at about twice the average rate. This measure would require high-mileage vehicles to be tested annually which would shorten the time they are emitting excess emissions prior to being repaired.April 26, 2007 95 Add Visible Smoke Test. Excess soot from smoking passenger vehi cles is estimated at about one and a half tons per day statewide and is a public health concern. An inspection for excessive smoke is currently not part of the Smog Check progr am, but soon will be due to newly enacted legislation (AB 187 0, Lieber, Chapter 761 of 2006) that establishes visible smoke as a cause for Smog Check failure.

Inspection of Light- and Medium-Duty Diesels. There are over 200,000 diesel passenger ca rs and trucks operating in California.

While diesel vehicles have low ROG emi ssions, older diesels tend to emit higher levels of NOx and particulate matter than gasoline vehicles. Diesel vehicles, however, are not currently required to ta ke part in the Smog Check program. This measure would develop a Smog Ch eck inspection program for diesel passenger cars and trucks that would al low identification and repair of highemitting diesel vehicles.

Inspection of Motorcycles. There are about 400,000 motorcycles registered in California. They are currently exempt from Smog Check. While motorcycles do not have a high rate of emission control deterioration, surveys i ndicate a high level of exhaust system tampering. This measure would require some form of motorcycle Smog Check inspections to help reduce excess motorcycle emissions.April 26, 2007 96 Estimated Emission Reductions

Baseline emissions reflect adjustment s not included in the SIP Emission Inventory Projections on ARB’s websit e. The adjustments include criteria pollutant benefits from the greenhouse gas limits for motor vehicles adopted in

2004 and emission reductions from the Carl Moyer Program.

Baseline emissions are for all light- and medium-duty passenger cars, SUVs and trucks, and all gasoline heavy-duty tru cks. Reductions have been estimated in the following manner:April 26, 2007 98 Low Pressure Evaporative Test —ARB staff has estimated the percent reduction in emissions from the low pressure te st using before and after repair data collected in two studies done by ARB and one U.S. EPA study. The percent reduction was estimated separately for hot soak, diurnal, and running loss evaporative emissions. The percent reductions were then applied to EMFAC baseline evaporative emissions for the light duty fleet in order to calculate evaporative emissions benef its in tons per day.

More Stringent Cutpoints —The reductions are based on more stringent initial inspection standards (cutpoints) taken fr om a study by Sierra Research using

failure rate data collected from the Califor nia, Arizona, and Wisconsin inspection programs. Sierra Research identified model year groups of vehicles for which cutpoints could be lowered and estimat ed the impact on emission rates for each group. The fractional changes in emi ssion rates were then applied to EMFAC

baseline emissions to calculate em issions benefits in tons per day.

Annual Inspections for Older Vehicles —Staff used the EMFAC emissions model

to estimate the emissions reductions of an annual inspection compared to biennial inspection. EMFAC allows t he user to choose either an annual or biennial program. Emission reductions were estimated by comparing the emissions with an annual progr am to those with a bienni al program for vehicles over 15 years old. 15 years of age wa s selected because this is the point at which vehicles start failing at twice t he fleet average yet account for less than 25 percent of Smog Check tests.

Annual Inspections for High Annual Mileage Vehicles —ARB conducted a voluntary inspection program on high mileage taxi cab fleets in the San Francisco and Los Angeles areas. Smog Check data suggest that up to 3 percent of the fleet accumulates high annual mileage. The estimated reductions from 20,000

taxicabs were ratioed to the assum ed 3 percent of t he enhanced program area fleet driven high mileage. We assumed t hat one-half of the 3 per cent of the fleet that are high annual mileage vehicles would be identified as accruing high annual mileage, tested annually, and repaired, re sulting in emission reductions.

Visible Smoke Test —Based on data from a survey done for South Coast AQMD,

Sierra Research has estimated that approximately 200,000 smoking gasoline vehicles are driven daily st atewide. Based on data from the South Coast survey

and data from Southwest Research Instit ute testing, the benefits of repairing a smoking vehicle average 0.25 gram/mile. We are assuming that half of the 200,000 smoking vehicles would fail the curr ent tailpipe test in Smog Check. We

have estimated benefits for the visible smok e test by assuming it would fail the other half (100,000) of the smoking v ehicles per biennial cycle, which equals 50,000 failures per year. Reductions st atewide are based on repairing 50,000 vehicles driving 30 miles per day with a 0.25 gram/mile total PM reduction.

Inspection of Light and Medium Duty Diesels - Benefits are based on an inspection program as stringent as t he current program for gasoline cars and trucks. We are assuming a diesel in spection program would get the sameApril 26, 2007 99 percent reduction in emissions that the current enhanced Smog Check program is achieving.

Inspection of Motorcycles —Benefits are based on assuming a motorcycle inspection program would get half of the percent reduc tion in emissions that the current enhanced Smog Check program is achieving.

Timing

Action: 2007-2008 Expected Implementation: By 2010

Staff Proposed SIP Commitment

ARB staff proposes to work with BAR to begin to implement the measure in 2010. ARB and BAR staff will initiate an effort to develop program improvements to achieve the reductions shown for the South Coast and San Joaquin Valley nonattainment areas in 2014, 2020, and 2023. The measure as implemented may provide more or less than the amount shown.April 26, 2007 100 Expanded Passenger Vehicle Retirement

The bulk of emissions from passenger vehi cles comes from older vehicles. The Smog Check program helps ol der California cars run cl eaner. To meet clean air goals, however, we need to reduce emissions from these older vehicles even

more. Owners of vehicles that fail Sm og Check inspections are currently given the option of fixing their vehicles or rece iving a monetary incent ive for voluntarily retiring them. This measure would expa nd the Smog Check vehicle retirement program to vehicles that are off-cycle from their Smog Check inspections.

It is estimated that the v ehicle retirement program c ould increase its scope from the current 18,000 vehicles per year statewide to appr oximately 50,000 per year in the South Coast and 10,000 per year in the San Joaquin Valley, which reflects retiring about half of one percent of v ehicles subject to Smog Check in each region. The annual retirem ent of these vehicles in the South Coast and San Joaquin Valley would result in combined ROG and NOx emissions benefits of 2 percent of passenger vehicle emissions in 2014.

Funding for vehicle retirement at both St ate and local program levels comes from fees on newer cars exempt from Smog Check. In creasing the scope of the program post 2010 would require additi onal State or local funding.

The measure as implemented may provide more or less than the amount shown.April 26, 2007 102 Modifications to Reformulated Gasoline Program

Gasoline fuel combustion is the majo r source of energy for passenger transportation. Since 1992, ARB has wo rked to ensure the use of cleaner burning gasoline to improve air quality th roughout the state. One of the many components of the most recent gasoli ne reformulation program, CaRFG3, was the removal of the oxygenate MTBE due to concerns with groundwater contamination. However, the substitu te oxygenate, ethanol, has resulted in greatly increased evaporat ive emissions due to f uel system permeation.

This proposed measure would make modi fications to the CaRFG3 program to

eliminate or offset all et hanol permeation effects. T he effects on ROG emissions from all gasoline-fueled on-road vehicles have been estimated to be a 3 percent increase in the South Coast and a 6 percent increase in the San Joaquin Valley. The effects are greater in the San Joaqui n Valley due to much higher overall temperatures that affect permeation.

ARB is scheduled to consider modifica tions to the CaRFG3 program in 2007.

Staff Proposed SIP Commitment

ARB staff proposes to commit to bring this measure to the Board by 2007. ARB staff will initiate a rule development pr ocess designed to achieve the reductions shown for the South Coast and San Joaquin Valley nonattainment areas in 2014,April 26, 2007 103 2020, and 2023. The measure as proposed by staff to the Board or adopted by the Board may provide more or less than the amount shown.April 26, 2007 104 Cleaner In-Use Heavy-Duty Trucks

Federal and State engine standards will ensure that by 2010 all new diesel heavy-duty trucks are 90 percent cleaner than new 2006 trucks. This tremendous progress is on top of a 65 percent reduction in NOx and an 85 percent reduction in particulate matter since 1990. Since trucks last a long time, we must bring newer trucks into the fleet at a faster pace, clean up older dirtier trucks, and keep the clean trucks clean longer to help meet air quality goals.

Between now and 2014 existing programs r educe heavy duty truck emissions by 50 percent. This proposed measure w ould reduce 2014 emissions another 30 percent. The measure would accomp lish these new reductions through a program to reduce emissions from the legacy fleet involving accelerating the turnover to new truck engines and retrofi tting the remaining trucks with emission reduction devices, and through an excess emissions program.

Legacy Fleet Emission Reduction Program

Newer heavy-duty trucks are typically used in long-haul service. After seven or eight years, they are often sold and their service is typically shifted to shorterhaul work. These trucks may remain in service within a given region for another twenty years or more.

An in-use truck program would focus on overcoming the slower rate of heavyduty truck turnover to cl eaner engines and retrofitting the remaining trucks with emission control devices such as parti culate matter filters. The most comprehensive way to accomplish this w ould be through an “in-use” fleet rule that would require truck owners to meet specified emission levels. The proposed measure would address fleets operating in California regardless whether they are registered out of state. The emission reduction impac t of the proposed in-use fleet program would be equivalent to r eplacing by 2014 approximately 30 percent of the oldest trucks with 2010 models year or newer trucks. The proposed measure would generate addi tional emission reductions beyond 2014, achieving

reductions needed to meet the ozone air quality standard.

ARB staff has recently begun informational workshops on a heavy-duty truck inuse fleet rule, and has started to i dentify and explore the many emissions inventory, technology, financia l, and logistical issues involved in crafting the most effective rule possible. ARB staff will be studying and requesting feedback from stakeholders on many issues, including: the characteristics of trucks registered outside of California; cost implications, especially to truck owner-operators, and ways to avoid any competitive disadvant age for various categories of truck owners; and the most efficient use of lim ited public incentive funds to achieve

maximum emission benefits and lessen financial burden on truck owners.April 26, 2007 105 Excess Emissions Program

An estimate of deterioration of emission controls has historically been built into ARB’s projections of future emissi ons. As new engine technologies are introduced over the next few years, we need to ensure that the complex engine

electronics and control devices used to ma ke trucks so much cleaner are not more prone to failure, tampering or malm aintenance, and that deterioration does

not reduce the benefits of t he new standards. As the 2010 new engine standards are implemented, we will evaluate t he in-use emissions and develop approaches

to reduce excess emissions from trucks.

Under an existing program, heavy-duty tru cks are inspected at random roadside locations for excessive smoke, and are inspected for tampered emission control systems. Owners of vehicl es that do not pass these inspections are issued citations that require prompt repairs and ca rry civil penalties. This measure could include an expansion of this program.

While the design and evaluation of the specific program features has yet to be determined, ARB staff estimates that th is concept has the potential to reduce NOx deterioration emissions by approximately 50 percent.

Auxiliary Engine Cold Ironing and Other Clean Technology Cleaner Main Engines and Fuel

Ships bring the majority of international ly traded goods to California. Due to the international nature of goods movem ent, marine vessels are subject to

international and national standards se t by the Internat ional Maritime Organization and U.S. EPA. However, ships are historically a largely unregulated sector. In 2006, ship emission s ranked as the largest contributor to SOx emissions, fifth largest contributor to NOx emissions, and seventh largest contributor to directly em itted PM2.5 in the South Coast. With the predicted growth in goods movement through Cali fornia by 2020 (especially through the Ports of Los Angeles and Long Beach), emi ssions from ships are expected to increase significantly.

In April 2006, ARB adopt ed the Emission Reduction Pl an for Ports and Goods Movement in California, which calls fo r aggressive measures for ships and other port-related sources. The proposed em ission reduction targets in these measures are the same goals set in that plan. Even before the adoption of the plan, work had begun to help meet its goal s. In December 2005, ARB approved an Auxiliary Engine Fuel Rule that will phase in cleaner low-sulfur fuel from 2007

to 2010. This rule will reduce SOx emissions from auxiliary engines by 96 percent, PM emissions by 83 percent, and NOx emissions by 6 percent beginning in 2010.

The proposed measures outlined below will continue to work toward the goals outlined in the goods movement plan to considerably reduce ship emissions. Marine fuel standards, cold ironing (port electrification), vessel speed reduction, and retrofitted diesel engines will ensur e cleaner air around ports and reduced regional emissions. These measures are split by the type of engine used on a ship. Typically, ships use auxiliary engines while they are do cked at the port or to run lights and other amenities while t hey are transiting. Main engines and boilers are used when ships are maneuveri ng within port waters or transiting throughout open waters.

Auxiliary Engine Measures

In addition to the Auxiliary Engine F uel Rule, a new proposed measure for reducing auxiliary engine emissions is at-dock modifications including cold ironing and other advanced pollution reduction systems such as the “hood”. Cold ironing allows ships to turn off their auxiliary engines and instead plug into an electrical system for power when they are docked at the port. This is extremely beneficial to surrounding communities as it reduces exposure to multiple pollutants. The “hood” is a device that fits onto a ship ’s exhaust stack and cleans the emissions. This measure would phas e in the number of ships that will be capable of using cold ironing and tec hnologies such as the “hood”. A combination of cold ironing and other at-dock technologies would reduce SOxApril 26, 2007 108 emissions by 54 percent in 2014 and 72 percent in 2023 and both NOx and PM emissions by 65 percent in 2014 and 82 percent in 2023.

Main Engine and Boilers

A Main Engine Fuel Rule, patterned after the Auxiliary Engine Fuel Rule, would help reduce emissions by introducing a cle aner, low-sulfur fuel beginning no later than 2010. This proposed rule would apply to ships using their main engine while maneuvering and tr ansiting near the Californi a coast and would reduce SOx emissions by 96 percent, PM emi ssions by 83 percent, and NOx emissions by 6 percent no later than 2010.

A highly effective measure to reduce main engine emissions would be to increase the use of cleaner new engines or retrofitted engines. The measure could be implemented via r egulation, incentives, vo luntary agreements, or a combination of these approache s. By 2014, ships visiting California ports would have either new engines or a mix of retrofit technology (e.g., technology similar to a catalytic converter on a passenger car) that would achieve an overall reduction of NOx and PM of 30 perc ent. In 2023, ships visi ting California would be equipped with an even cleaner technology mix, resulting in a 70 percent reduction of NOx, 50 percent reduction of PM, and 40 percent reduction of SOx.

Vessel Speed Reduction (VSR) is an additio nal measure that would reduce main engine ship emissions. Presently, ships entering the Ports of Los Angeles and Long Beach have voluntarily agreed to r educe their speed to 12 knots within 24 nautical miles of the ports. It is es timated that there is a 48 percent compliance rate associated with this vol untary measure. In order to further reduce main engine emissions, ARB would require ships to reduce their speeds

to 12 knots within 40 nautical miles of the Ports of Los Angeles and Long Beach. The efficacy of the VSR progr am in reducing emissions changes over time as the vessel speeds are a function of the vessel ty pe. It is estimated that ships will get larger and, therefore, their speeds will change. VSR is 30-35 percent effective in reducing SOx emissions, 40-50 percent e ffective in reducing PM2.5 emissions, and 35-50 percent effective in reduc ing NOx emissions over time.

The measur e as proposed by staff to the Board or adopted by the Board may provide mo re or less than the amount shown.April 26, 2007 111 Port Truck Modernization

Trucks serving California ports are a vita l part of the goods movement system. Trucks transfer incoming cargo contai ners from the ports to intermodal

distribution centers for tr ansport via long-haul rail or truck to their ultimate destination in California or throughout t he U.S. Trucks also carry agricultural products from the Central Valley and ot her farming regions, and exports, to the ports for shipment overseas. Port-related truck activity is growing. The number of containers carried by truck to and from the Ports of Los Angeles and Long Beach, for example, is expected to grow by a factor of 2.5 within twenty years. Because trucks in port service tend to be older and dirtier than the truck fleet as a whole, it is im portant that the im pact of these vehicles be mitigated more quickly to address community health issues and to meet air quality goals.

This proposed measure woul d reduce NOx and diesel PM 2.5 emissions from the existing port truck fleet, as well as additional trucks entering port service. The basis for this strategy closely follows the goals outlined in the Emission

Reduction Plan for Ports and Goods Move ment in California (April 2006). Rulemaking is currently in progress for the port truck modernization rule, which would take place in two phases. The Ports of Los Angeles and Long Beach are also developing approaches to reduce port truck emissions on a parallel track. A mix of regulatory and other actions may be used to achieve the emission reduction target.

With the current ARB concept, trucks in r egular port service that are model year 1993 and older would be replaced with 1998 and newer trucks by 2011. In addition, all trucks in regular port service would be retrofitted with verified devices that reduce diesel PM by 85 percent or more. Retrofits that also provide NOx reductions would be used to the greates t extent feasible. The second phase would require pre-2003 tru cks in regular port servic e to meet or exceed 2010 federal engine standards by the end of 2017, and pre-2007 trucks in regular port

service to meet or exceed 2010 federal engine standards by the end of 2019. Additionally, the proposal would require trucks entering port service for the first

time between 2008 and 2011 to meet or exceed 2003 federal engine standards and be equipped with diesel particulate f ilters. Trucks entering port service

between 2012 and 2014 would need to m eet or exceed 2007 federal engine standards, and trucks entering port service in 2015 and later would need to meet

or exceed 2010 federal engine standards.

This proposed measure would reduce port truck NOx emissions in the South Coast Air Basin by about 10 perc ent in 2014 and 50 percent in 2023. Also, diesel PM emissions from port tr ucks in the South Coast Air Basin would be reduced by more than 50 per cent in 2014.

The reductions from this measure would complement the reductions achieved by the proposed cleaner in-use hea vy-duty truck measure. The regulation currently being developed for port trucks would app ly only to those heavy heavy-duty trucks in primary port service. The priv ate fleet rule currently under developmentApril 26, 2007 112 would provide the reductions cited for the in-use heavy-duty truck measure by including trucks not in port service as well as trucks in the medium heavy-duty category.

Baseline emissions are fo r port trucks, based on inventories developed for the

Emission Reduction Plan for Ports and Goods Movement. Emission reduction estimates are based on the assumption that port trucks are older, on average, than the fleet as a whole (age dist ribution was based on a 2002 study by Starcrest International). The number of tr ucks in regular port service is projected to grow from approximately 12,000 in 2005 to 15,000 in 2010, 18,000 in 2015 and 21,000 in 2020. Staff a ssumed that port trucks make trips of lower average speed (35 mph), owing to short hauls to distribution centers and congested conditions near the ports.

Port truck emissions are small for the S an Joaquin Valley so reductions for this measure are not significant. Goods move ment-related emissions from trucks in the San Joaquin Valley are generated prim arily by line-haul trucks and not port

trucks. Line-haul truck emissions ar e significantly reduced in the proposed cleaner in-use heavy-duty truck measure.

Line-haul locomotives used to pull rail cars long distances account for about 95 percent of total train emissions. U. S. EPA proposed new Tier 4 standards to reduce NOx and PM emissions by 90 perc ent. These emission standards would build on existing federal requirements for using low sulfur diesel fuel. They include new engine standards and rebuild standards, and require aftertreatment technology. Since the useful life of a locomotive can exceed 30 years, the accelerated use of Tier 4 or equivalent technology is necessary to provide diesel

PM and NOx reductions needed to meet attainment deadl ines. ARB is pushing

U.S. EPA to accelerate introduction of Ti er 4 standards on an ear lier timeframe, beginning in 2012.

The proposed measure calls for replacing ex isting locomotive engines with Tier 4 engines beginning in 2012 and conducting co ncurrent rebuilds of older engines

to Tier 2.5 standards. This can only occur once U.S. EPA accelerates implementation of the Tier 4 engine standards for locomoti ves. It is estimated that by 2023, this measure would reduce NOx by 70 percent and direct PM2.5 by about 75 percent.

California service.April 26, 2007 115 Clean Up Existing Commercial Harbor Craft

Commercial harbor craft are marine vessels that operate primarily along

California’s coastline and inland waterwa ys. They include tugboats, work boats, crew/supply boats, ferries, excursion boats, commercial and sport fishing boats, and other harbor vessels. The diesel pr opulsion and auxiliary engines used on these vessels were built for long life and hav e essentially uncontrolled emissions.

U.S. EPA adopted harbor craf t engine standards that apply to new engines beginning in 2004. The engines meeti ng the new U.S. EPA standards have roughly 50 percent less NOx t han uncontrolled engines. Since the useful life of harbor craft vessels is so long, t he benefits of new engine standards accrue slowly over time. However, to accele rate emission reductions, many of these vessels can be repowered with newer, cleaner engines.

There are also emission control technologies , called “add-on” controls or retrofits, that can reduce both NOx and diesel parti culate matter. Retrofit control technologies have been shown to dramatical ly reduce emissions when used with heavy-duty diesel engines in land- based operations and can be adapted to marine applications.

ARB is in the process of developing a r egulation that would require owners of existing commercial harbor craft to replace old engines with newer cleaner engines and/or to add retrofit emission c ontrol technologies. It would address both propulsion and auxiliary engines. The regulation would take into account the fact that harbor craft vessel types are diverse and may require various combinations of emission reducing strategies and that some vessel configurations may not accommodate retrofit s. Fishing boats in particular will be difficult to retrofit and may face diffi cult unique economic constraints.

The proposed regulation is one of the measures in AR B’s Goods Movement Plan and is scheduled for adoption in 2007. ARB staff estimates that the harborcraft regulations will reduce NOx and PM em issions 30 percent by 2014, and 40 percent by 2020,based on the capabilities of existing control technologies.April 26, 2007 116 Estimated Emission Reductions

The measure as proposed by staf f to the Board or adopted by the Board may provide

more or less than the amount shown.April 26, 2007 117 Cleaner In-Use Off-Road Equipment

Adopted emission standards for new off-ro ad diesel engines are becoming increasingly more stringent, ensuring that new construction, mining, industrial, oil drilling and airport ground support equipment become pr ogressively cleaner.

The cleanest standards for NOx emissions in these categories will phase in from 2013-2015. However, large diesel o ff-road equipment with more than 25 horsepower remain in use for long periods of time, often 25 years or more. This long life means that new, lower emitting engines are introduced into fleets relatively slowly with the result th at the emission reductions and associated

health benefits from these cl eaner engines will also be slow to materialize. Accelerating the introduction of cleaner engines and emissions control technologies into the statewide fleet is necessary to meet air quality standards.

This proposed measure would require owners of equipment larger than 25 horsepower to meet a stringent average emissions level across all of their equipment. The fleet average approach provides equipment owners flexibility in how they will comply, including: sw apping older, dirtier engines with newer, cleaner engines; purchasing newer equi pment (with cleaner engines); and, adding emission control devices to older eng ines. It also allows fleet owners to maintain a fleet with some engines wh ich are cleaner than the fleet average and others which are dirtier, so that, on average, the fleet meets the target. ARB staff is also proposing idling limits similar to those the Board has adopted for heavy duty trucks.

ARB staff has proposed a statewide in-u se off-road diesel equipment regulation which could require initial NOx and PM emissions averages to be met, with increasingly lower emissions averages over time. Staff began work on the rule in 2004 as part of the Diesel Risk Reduction Progr am. During early SIP development work in 2006, staff identifi ed the necessity for large NOx emission reductions from off-road equipment and otherdiesel sources to meet the healthbased federal air quality standards. C onsequently, staff revised the control concept extensively to meet California’ s clean air needs relative to diesel particulates, ozone, and PM2.5.

This measure would reduce NOx emissions from large diesel off-road equipment in the South Coast Air Basin by approx imately 10 percent in 2014 and by about 30 percent in 2023.April 26, 2007 118 Estimated Emission Reductions

Baseline emissions are from the OffRoad2007 model.

Emission reduction estimates are based on expected emission reductions from ARB’s proposed In-Use Off-Road Diese l Vehicle rule currently under development. Because the proposed rule is under development, the estimated reductions are subject to change.

The rule proposal applies declining fleet averages for large fleets beginning in 2010. For NOx, the fleet averages fo r 2014 for most engine sizes are more stringent than Tier 1 emission levels. The corresponding PM fleet averages for

2014 are cleaner than Tier 2 em ission levels. In 2020, fleet averages for NOx and PM are more stringent than Tier 3 emission levels. The means to reach these fleet averages are left to the equipm ent owners to decide. However, if a

fleet cannot meet the NOx av erages, it must turnover 8 percent of its total horsepower per year to cleaner engines (mi nimum Tier 2 engine) in the initial years and 10 percent per year in years after 2015. A fleet must retrofit 20 percent of its total horsepower with diesel particulate filters if it cannot meet the PM average. The rule would also restrict unnecessary idling.

New engines used in agricultural operati ons must meet the same standards as other off-road engines, ensuring that new equipment become progressively cleaner. Just as in other off-road applicat ions, diesel agricultural equipment can remain in use for long periods of time. This long life means that new, lower emitting engines are introduced into fleets rela tively slowly with a direct impact on the pace that emission reductions materialize.

The cleanup of agricultural in-use equipment is primarily an issue in the San Joaquin Valley with its large agricultu ral economy. Natural turnover of the agricultural fleet will reduce emission sign ificantly by the Valley’s expected 2024 ozone attainment deadline. Modeling for the Valley’s PM2.5 SI P due in 2008 will

show what accelerated fleet mode rnization may be needed. Once that information is available, ARB staff will quantify reductions from this measure. ARB staff is also supporting efforts to obtain additional incentive funding to accelerate progress.

Recreational boat engines are broadly di vided into two categories: outboard boats/personal water craft (PWC) and i nboard/sterndrive. Outboard and PWC motors until recently were predominantly 2-stroke engines. Inboard/sterndrive engines are typically automotive spar k-ignition engines adapted for boats that must now comply with a 5.0 g/kW-h r exhaust standard by 2009, which can be achieved with three-way catalytic converters and oxygen sensor feedback controls. Although ARB previously adopted exhaust emission standards for outboard/PWC engines, lower exhaust standards to further reduce emissions are possible by adapting the emission contro l technology used for inboard/sterndrive engines. This measure calls for the im plementation of a tighter, catalyst-based exhaust standard of 5.0 g/kW-hr for out board/PWC engines to be phased-in by 2013. Only 4-stroke engines are expected to be able to comply with this tighter

standard.

Evaporative emissions represent about one fourth of the total ROG emissions from recreational boat engine s. There are no state or federal evaporative emission standards for any type of recreatio nal boats. This measure calls for an evaporative emission standard that will address all sources of boat evaporative emissions (tank, carbon canisters, fuel lines, etc.). The technology needed to achieve evaporative standards for boats is readily adaptable fr om that used in automobiles and small off-road equipment.

Exhaust Standards

Exhaust emissions from off-road recreational vehicles are controlled to a much lesser extent than on-road motorcycles or on-road cars and trucks with the result that this category of vehicles is showin g an increase in emissions into the future.

In 1994, ARB approved exhaust emissi on standards and test procedures for off-road recreational vehicles, including off-highway motorcycles and all terrain vehicles (ATVs). In 1998, ARB revised the rules to allow non-compliant vehicles to be sold and operated outside the summer season or in locations where ozone

levels are lower.

Off-road recreational vehicles lag in emission reductions for a number of reasons including technical limitations, cost, and ta mpering. Another c oncern is that the California market is not large enough for off-road recreational vehicle manufacturers to produce vehicles t hat would comply with more stringent

California exhaust standards. This c ould lead to compliance problems if consumers either purchase off-road recreat ional vehicles out-of-state or falsely certify that the vehicles they purchase are intended for use in competition. The most effective strategy would be for U.S. EPA to establish tighter exhaust

standards for all off-road recreational vehi cles, thereby precluding the potential for California consumers to purchase and operate non-complying (and higher emitting) vehicles.

This measure calls for reducing exhaust emissions by 50 percent from new offhighway motorcycles and ATVs beginni ng in 2012 using proven automotive and on-road motorcycle exhaust emission reducti on technologies. Due to the high fleet turnover and overall growth of t he fleet, ARB staff es timates that the

measure would reduce ROG exhaust emi ssions from off-road recreational vehicles 25 percent by 2014 and 50 percent by 2023.

Evaporative Standards

In 2002, U.S. EPA approved a rule that r equired all off-road recreational vehicles to comply with evaporative standards beginning with 2008 vehicles. However, the standards only control permeation from the fuel tank and hoses. In July 2006, ARB approved evaporative emissi on standards that harmonized with existing U.S. EPA regulations.

This measure would reduce ROG evaporat ive emissions by 50 percent from off-highway motorcycles and ATVs begi nning in 2012 using proven automotive and on-road motorcycle evaporative emission reduction technologies. Due to the high fleet turnover and overall growth of the fleet, ARB staff estimates that the measure would reduce ROG evaporative emissions from off-road recreational vehicles 25 percent by 2014 and 50 percent by 2023.April 26, 2007 124 Estimated Emission Reductions

Portable Outboard Marine Tank Evaporative Standards

Portable outboard marine tanks (OMT) ar e small-capacity tanks (usually less than 12 gallons) that supply fuel to marine outboard engines. Unlike larger vessels with permanently mounted fuel t anks, many small and medium size

outboard boats use removable tanks to allow both the engine and fuel tank to be removed for transport or storage. OM Ts are not subject to any emission standards and as a result have relatively high evaporative emissions. DMV and

other data indicate that there were approximately 200,000 registered outboard

vessel owners in California in 2005. If we assume one tank per outboard, the statewide inventory would be 200,000 OMTs with statewide emissions of approximately six tons per day. Baseline emissions fo r future years and regions

of the state were scaled from this estima te on the basis of emission inventories of evaporative emissions from outboard boat engines sma ller than 15 horsepower.

Diurnal and permeation standards fo r OMTs and associated equipment are expected to have the same emission reduc tion efficiencies as controls required by ARB’s 2005 regulation for portabl e fuel containers, and would reduce emissions by 50 percent in 2014 and 75 per cent in 2023. This measure would be applied to new tanks, resulting in a phas e-in over the useful lives of existing

tanks.

Refueling Gasoline Tank Evaporative Standards

Refueling gasoline tanks (from 30 to 100 gallons) are usually mounted on a

vehicle and used to refuel other motor v ehicles. Some examples include tanks on recreational vehicles, like toy haulers, for fueling off-highway recreational vehicles or tanks on pickup trucks for f ueling off-road or agricultural equipment. There are an estimated 150,000 refueling tanks in California

ARB staff are currently conducting surve ys to determine accurate populations as well as testing to calculate more accurate emissions. Rough preliminary statewide estimates of evaporative emissi ons from refueling gasoline tanks are approximately six tons per day. Future year and regional bas eline estimates are

scaled from this statewide estimate on the basis of recreational offroad vehicle evaporative emissions.

Setting evaporative standards for refue ling tanks would reduce ROG emissions by 60-70 percent, depending on which technology is utilized. Control technologies being considered include passive purge carbon canisters and insulation. These technologies would be applied to new tanks and would be phased-in over the useful liv es of existing tanks.April 26, 2007 126 Gas Station Refueling Ho se Evaporative Standards

Gas station refueling hoses are co-axial hoses that transfer f uel from the filling station pump to a vehicle’s fuel tank and return displaced gasoline vapors from

the vehicle fuel tank to the gasoline storage tank. Evaporative emissions occur through the hose material. There are an estimated 120,000 gas station refueling

hoses statewide with estimated emi ssions of three tons per day.

Setting evaporative standards for gas stat ion refueling hoses would reduce ROG emissions by 70-98 percent, depending on which technology is utilized. These estimates are based on previous standards for low permeation vehicle fuel hose and initial ARB and industry testing results.

Estimated Emission Reductions

Emission inventories are being reasse ssed for these evaporative source categories. For SIP purposes, emissi on reductions are not quantified for these measures so no benefits are included in the proposed SIP.

The measures are described here for info rmational purposes only. Reductions

from these measures will be accounted for in future SIP updates. For information purposes only, reductions from the three measures combined are expected to be about 3 tons per day in the South Coast in 2020.April 26, 2007 127 Enhanced Vapor Recovery for Above Ground Storage Tanks

Above ground storage tanks ar e large gasoline storage tanks used extensively in agricultural operations. Typical tanks have capacities ranging from 250 to 12,000 gallons. Above ground storage tanks are becoming increasingly popular due to their superior leak detection capabilities. Because these tanks are exposed to ambient air temperatures , emissions are greater than from underground tanks. Annual statewide ROG emissions from all tanks in 2004 totaled 3.1 tons per day. Emission reductions are possible and feasible with an enhanced vapor recovery certification process and new performance standards and specifications.

This proposed measure calls for reduci ng emissions by 90 percent from new above ground storage tanks, by 76 perc ent from retrofitting existing nonagricultural tanks, and by 60 percent from retrofitting existing agricultural tanks. This measure would be implemented begi nning in 2007, and by 2011 would

reduce statewide ROG emissions from tank s by two tons per day. The estimated

control efficiencies are based on field testing of proposed controls. The retrofitting of existing tanks woul d be phased in between 2007 and 2011 with 25 percent of tanks being converted each y ear. ARB staff is currently analyzing what the emission reductions would be for each region.

Staff Proposed SIP Commitment

ARB staff proposes to commit to bring this measure to the Board by 2007. ARB staff will initiate a rule development pr ocess designed to achieve the reductions shown for the South Coast and San Joaquin Valley nonattainment areas in 2014,April 26, 2007 128 2020, and 2023. The measure as proposed by staff to the Board or adopted by the Board may provide more or less than the amount shown.April 26, 2007 129 Consumer Products Program

Chemically formulated consumer products such as automotive care products, household care products, and personal ca re products have been regulated as a

source of ROG emissions in five rulema kings since 1989. As a result of these measures, statewide emissions from c onsumer products in 2010 will be reduced 40 percent from uncontrolled levels. Desp ite this progress, population growth in the years ahead is expected to reverse the downward trend of emissions from consumer products as early as 2008, after the latest standards become effective. The magnitude of emissions from this sector indicates that additional controls for this sector remain important, even though the average photochemical reactivity

of the ROG emissions from the consumer product se ctor is approximately onethird that of motor vehicle exhaust. Consumer products are expected to become the largest source of ROG emissions in the South Coast Air Basin, and the third largest source in the San Joaquin Valley Air Basin by 2020

.

This proposed measure would conti nue ARB’s commitment to reduce ROG emissions from consumer products. The current program uses industry surveys to gather information about sales trends and product formulations. Staff uses survey data along with trade journals, pat ents, and other technical information to propose mass-based ROG limits. Staff will continue to investigate any and all opportunities for emission reductions from mass-based limits by taking advantage of emerging low-em itting technologies. Howe ver, the ability to achieve significant reduction from mass- based standards is wani ng, so staff will likely be shifting the focus to other potent ial emission reduction opportunities.

One such measure would include investi gating emission reduction opportunities through reactivity-based standards in most categories. A reactivity-based approach relies on the scientific principle t hat different chemical compounds form

different amounts of ozone in the atmosphere, ra ther than the mass-based approach that reduces ozone formation by reducing all reactive organic gases.

In the future, it is likely that further emission reductions from the consumer products source category will not be feasib le using conventional approaches. Staff will work with stakeholders to explor e alternative market-based mechanisms that would encourage the development, di stribution, and purchase of cleaner, very low, or zero emitting products. Ex amples of mechanisms to explore are a multi-media labeling program, program s where companies set their own emissions reduction goals, and the use of the media for public education. If these mechanisms cannot produce meaning ful emission reductions from the consumer products source category, t hen other approaches would be evaluated. Examples of alternative approaches ar e the purchase of ROG credits and the funding of special projects to reduce emissions or acce lerate reductions from pollution sources outside of the consumer products industry.

The above approaches could be implement ed through several rulemakings and would achieve approximately 30-40 tons per day ROG reductions statewide, equivalent to 13-17 tons per day in the South Coast, in the 2008 to 2014

timeframe. The 2006 measure was adopted by the ARB Board inApril 26, 2007 130 November 2006 with phase-in impl ementation from 2008 to 2010.

The Department of Pesticide Regulati on’s (DPR) proposed 2008 Pesticide Plan includes strategies to reduce ROG emi ssion from pesticides through regulation of fumigant pesticide use, regulatory standards for registration of liquid pesticides, and strategic partnership agreements im plementing pest management practices and technologies that use le ss pesticide product. This DPR Plan goes beyond reducing ozone precursor emissions by also addressing air toxic exposures associated with pesticide use. This pr oposed SIP commitment reflects only nearterm actions. Future DP R actions will be included in SIP updates after DPR takes regulatory action.

Near-term Measures - Fumigant Regulations

DPR would implement regulations in 2008 that set a limit on the aggregate ROGs that may be emitted from field fumigati on during the ozone season in the certain areas. In addition, the 2008 regulations would specify the allowable application methods that may be used in field fumigat ion statewide. Certain high-emission application methods would be excluded fr om that list. In 2008, emission reductions of 2.5 tons per day (tpd) woul d be achieved in the San Joaquin Valley.

The commitment for near-term emission reductions from the 2008 regulations would implement the commi tment for pesticide emission reductions detailed in the 1994 SIP in the San Joaquin Valley.

San Joaquin Valley Inv entory Adjustments: As part of the San Joaquin Valley 2007 Ozone Plan development, the San Joaquin Valley air district made several adjustment s to the emission inventories. (Further explanation below.)May 7, 2007 Appendix A 3 Further Baseline Adjustment Explanations

HHDD Trucks. Adjustment for 2005 Heavy-Duty Truck VMT

ARB’s on-road motor vehicle emissions m odel (EMFAC2007) estimates for heavy heavy-duty truck vehicle miles traveled (VMT) for year 2005 were adjusted to match transportation agency VMT estimates.

To calculate VMT for years 2000 through 2005, ARB staff used populat ion data from the Department of Motor Vehicles (DMV) toget her with mileage accrual rates from the Bureau of Automotive Repair. As resu lt, default EMFAC2007 VMT for 2000 through 2005 can differ from transportation agency esti mates, which are transportation model outputs. This was the case for the 2005 heavy heavy-duty VMT estimate. For SIP purposes, State law directs ARB to use transportation agency VMT data when it is

available. Ozone and PM2.5 ai r quality modeling was done for 2005, making it a critical year for the SIP. Therefor e, ARB staff applied an extern al factor to heavy heavy-duty

truck emissions for 2005 that matched EMFA C2007 VMT to transportation planning agency VMT.

Reflash. Heavy-Duty Diesel engine Software Upgrade

ARB staff estimates that overall benefits of the software upgrade regulation plus related actions provided approximately 38 tons per day of NOx emi ssion reductions statewide in 2007. This is within the range of the original staff estimate of 30 to 40 tons per day. Reductions included in the adjustment bey ond those required by the now invalidated regulation come from vol untary upgrade programs, ongoi ng engine rebuilds, engines upgrades by manufacturers exempt from the regulation, and interstate trucks.

Pesticides/Fertilizers. Pest icide ROG Inventory Adjustments

The California Department of Pesticide Re gulation (DPR) is the lead agency for tracking pesticide usage. DPR provided two sets of pesticide emissions inventory updates for

ozone nonattainment areas. These data are in the attached tables.

• In October 2006, DPR provided pesticide emissions based on the latest pesticide use (2004 Pesticide Use Report) data.

• Subsequently, DPR provided updated pes ticide emissions es timates for five areas based on a review of recently pub lished literature, in cluding monitoring studies demonstrating lower emissions when fumigant applications are tarped, irrigated after application, or applied thr ough drip irrigation systems. The five

areas are: - Sacramento - San Joaquin Valley - Southeast Desert (Antelope Valley , Western Mojave Desert, and Coachella Valley 8-ho ur nonattainment areas)May 7, 2007 Appendix A 4 - Ventura

- South Coast

San Joaquin Valley Air Pollution Cont rol District Emissions Inventory Adjustments

As part of the San Joaquin Valley 2007 Ozone Plan development, the San Joaquin Valley Air Pollution Control District (S JVAPCD) made several adjustments to the

emission inventories. The inventory adjustments include tw o types of refinements:

• To account for recent district rulemaki ng activities, such as District rule 4570 –

Confined Animal Facilities.

• To provide an initial accounting of prev iously un-inventoried source categories, such as emissions from green waste composting and biosolid management.

These adjustments are described in greater detail in Appendix B of the San Joaquin Valley 2007 Ozone Plan, as adopted by the SJVAPCD Governing Board on April 30,

### Appendix B

110(a)(2) Infrastructure SIP(This page intentionally left blank.)May 7, 2007 Appendix B 1 Introduction and Background

Section 110 (a) of the Clean Air Act (CAA) requires states to submit an implementation plan to the U.S. EPA Administrator that prov ides for implementation, maintenance, and enforcement of national ambient air qualit y standards. Section 110(a)(2) lists the elements that are to comprise the implemen tation plan. Several of the elements in §110(a)(2) specifically address the need for states to demonstrate the ability to implement, maintain, and enforce the air quality standards. These elements are sometimes compiled and submitted separat ely in what is referred to as an

“infrastructure” SIP. This document is the infrastructure SIP for the new 8-hour ozone and PM2.5 air quality standards.

The elements of §110(a)(2) are listed below. Two elements that are not part of an

infrastructure SIP but addressed separately elsew here are underlined.

• Enforceable Emission Limitations and Other Control Measures ( §110(a)(2)A)) (see Appendix G)

• Air Quality Monitoring, Compila tion, Data Analysis, and Reporting (§110(a)(2)(B))

• Enforcement and Stationary Source Permitting (§110(a)(2)(C)

• Interstate Transport ( §110(a)(2)(D)) (see Appendix C)

• Resources, Conflict of Intere st, and Emergency Backstop (§110(a)(2)(E))

• Stationary Source Emissions Moni toring and Reporting (§110(a)(2)(F))

• Emergency Powers and Contingency Plans (§110(a)(2)(G))

• SIP Revision For Revised Air Quality Standards or New Attainment Methods (§110(a)(2)(H))

• SIP Revisions for New Nonattainment Areas (§110(a)(2)(I))

• Consultation and Public Notification (§110(a)(2)(J))

• Air Quality Modeling and Reporting (§110(a)(2)(K))

• Major Stationary Source Permitting Fees (§110(a)(2)(L))

• Consultation with Local Entities (§110(a)(2)(M))

Most of these elements are addressed in the comprehensive §110(a)(2) SIP submitted in response to the CAA of 1970 and approved by U.S. EPA in 1979 in 40 CFR 52.220.

This submittal continues to affirm AR B’s commitment to comply with §110(a)(2) requirements and is incorporated by reference into this submittal.

The following discussions respond to t he new elements required by the 1990 CAA

Amendments and commitments required by the adoption of new ozone and PM2.5 air quality standards.May 7, 2007 Appendix B 2 § 110(a)(2)(B) Air Quality Monitoring, Co mpilation, Data Analysis, and Reporting

States are to establish and operate devices, methods, systems, and procedures to monitor, compile, and analyze ambient air quality data and to provide the data to

U.S. EPA.

California has an extensive air quality moni toring network operated by ARB and local air quality districts that collects air quality dat a that are compiled, analyzed, and reported to U.S. EPA. ARB’s website contains up-to- date information about air quality monitoring, including a description of the network and information about monitoring of ozone, PM2.5, and meteorology. See http://www.arb.ca.gov/aaqm/aaqm.htm with links to all elements of the program, and t he recent report on ARB’s PM 2.5 monitoring program at http://www.arb.ca.gov /pm/pm25_monitor_2005.pdf

.

In addition to the network of federally-approved reference m onitors that measure PM2.5 mass, ARB operates continuous PM2.5 mass monitors. For PM2.5 speciation, ARB analyzes filters collected by a network of reference monitors located throughout

California with concentrations in PM2.5 nonattainment areas. The PM2.5 data can be

accessed from two interactive databases: Aerometric Data Analysis and Management (ADAM), that provides historical data, and the Air Quality and Meteorological Information System (AQMIS), that provides real-time data. More details about ARB’s Air Monitoring Program, including monitoring pr ovided by local air districts, can be found

at http://www.arb.ca.gov/aaqm/mldaqsb/amn.htm

.

The 2006 California Almanac of Emissions and Air Quality includes a five-year summary of PM2.5 air quality data. This report can be found at http://www.arb.ca.gov/aqd/alma nac/almanac06/almanac06iu.htm

.

ARB commits to continue to operate an air qua lity monitoring network that complies with U.S. EPA requirements and to provide quarte rly reports of compiled and analyzed air quality monitoring data to U.S. EPA.

§ 110(a)(2)(C) Enforcement and Stationary Source Permits

States are to implement a pr ogram for the enforcement of control measures associated with the “attainment SIP” and a permi t program for stationary sources.

ARB’s Enforcement Program covers mobile and stationary sources, consumer products,

and fuels. Details about the program can be found at http://www.arb.ca.gov/enf/enf.htm

.

ARB reviews and audits the programs of the local air pollution control and air quality management districts (districts) as a part of its oversight role with respect to districts in

California and in accordance with Section 41500 of the Health and Safety Code. In addition, ARB reviews district rules at the draft, propos ed, and adopted stages of their development to ensure that t he rules meet all applicable stat e and federal requirements.May 7, 2007 Appendix B 3 ARB maintains a rule review database access ible to the public to make comments and rules easily accessible.

ARB does not have authority to issue permits to stationary sources of air pollution. The responsibility for permitting such sources rests with the local air districts. This includes prevention of significant deteriorati on (PSD) and new source review (NSR) preconstruction permitting programs for at tainment and nonattainment pollutants, respectively. California Health and Safety Code Section 39002 grants to ARB the ability to undertake control activities in any area w here it determines that districts have failed to meet the responsibilities given to it for the control of air pollu tion from stationary sources. District permitting regulations ar e federally enforceable because all have been approved by U.S. EPA as part of the state SIP. Local air district permit programs are

discussed at http://www.arb.ca.gov/ permits/permits.htm

.

ARB commits to the continued enforcement of control measures for which it has jurisdiction and the continued oversight of local district permitting and enforcement programs with respect to meas ures required by the CAA.

§ 110(a)(2)(E) Resources, Conflict of Inte rest, and Emergency Backstop

States are to provide assurances t hat (i) adequate personnel, funding, and legal authority will be available to carry out the SIP; (ii) a majority of it s state board members represent the public interest and do not derive a significant po rtion of their income from entities that are subject to permits, and that conflicts of interest of members be adequately disclosed; and (iii) the State has responsibility for ensuring adequate implementation of plan provisions to be carried out by local districts.

The California Legislature annually approves ARB’s funding and personnel resources for carrying out the programs of the SIP to demonstrate attainment of the PM2.5 and 8-

hour ozone standards. Distr icts’ budgets are approved annual ly by each district’s governing board. The annual bu dget process provides a periodic update that enables ARB and districts to adjust fundi ng and personnel needs. While it is not legally possible for ARB and districts to provide specific commitments about future year budgets (funding and staff resources) , the annual budget appr opriations process undertaken by the California State Legislat ure enables ARB to present a request for resources required to meet the mandates of the federal Clean Air Act. Since ARB’s Clean Air Act-mandated programs have rece ived State funding for more than 30 years, and since there is consistently strong public support in California for providing clean air, it is reasonable to assume that implementation of the Clean Air Act mandates in California will continue to obtain the necessary funding.

Through fiscal year 2006-2007, about 90 percent of ARB’s funding is devoted to meeting the Clean Air Act mandates. The majori ty of ARB’s budget currently consists of

dedicated funds that are collected from regulated emission sources and can only be used for air pollution control. These dedicate d fees are periodically adjusted in order to provide necessary funding for the ARB’s progra ms. Air districts re ceive funding fromMay 7, 2007 Appendix B 4 fees paid by regulated businesses, motor ve hicle registration fees, state and federal grants, and other local source s. Collectively, the 2006-2007 ARB and local air districts’ budgets total about $685 million with about 3,100 fu ll-time equivalent staff positions.

California Government Code Sections 87100-87105 specify confli ct of interest requirements for members of ARB and loca l district boards. These requirements specifically prohibit all stat e and local public officials from participating in governmental decisions for which they have a financial interest and also require ARB and local districts to develop conflict of interest policies to meet thes e legal requirements.

California Health and Safety Code Secti on 39002 grants to ARB overall regulatory authority for local districts’ programs and pow er to undertake a district’s air pollution control programs if the ARB determines that a district has failed to meet the responsibilities given to it by this secti on or by any other provision in State law.

ARB commits to actively maintain programs for the enforcement of control measures included in the approved SIP and measures requi red by the CAA.

§ 110(a)(2)(F) Stationary Source Em issions Monitoring and Reporting

States are to require the installation, maintenance, and replacement of equipment to monitor stationary sources of emissions by the owners or operator s of these sources and the provision of periodic reports on these emissions.

40CFR51.214 requires every SIP to include requirements for the monitoring of emissions from major stationary sources as specified in 40CFR51 Appendix P. Every air district in California has adopted regulat ions to implement the requirements of 40CFR51.214, and all of these district regulations have been approved by U.S. EPA as part of the state SIP. California Health & Safety Code Section 42700 et seq encourages districts to require emission monitoring devic es on major stationary sources, and many districts have adopted stati onary source monitoring re gulations in response.

ARB maintains a database with emissions data for more than 10,000 stationary source

facilities in California at http://www.arb.ca.gov/ei/disclaim.htm . In addition, ARB maintains the latest reports of em issions from stationary sources at http://www.arb.ca.gov /ei/emissiondata.htm where these emissions can be viewed from a statewide, air basin, or county level, by s ource category. The local air districts are responsible for providi ng these data to ARB.

ARB commits to continue its oversight of air district stationary source monitoring requirements and to the repor ting of data collected by such monitoring activities.May 7, 2007 Appendix B 5 § 110(a)(2)(G) Emergency Powe rs and Contingency Plans

States are to provide for aut hority comparable to that in Section 303, which provides legal authority to the U.S. EPA to halt t he emission of air pollutants causing or contributing to injury to public or welfare. U.S. EPA is authorized to either bring a lawsuit in federal court or, if such civil acti on cannot assure prompt protection of public health or welfare, to issue such orders as may be necessary to protect public health or

welfare or the environment. In addition, states are to provide for adequate contingency plans to implement such authority.

The authority granted to the U.S. EPA Administrator is vested in ARB and the air pollution control/air quality m anagement districts in Califor nia under California Health & Safety Code Section 42400 et seq. These sections apply to a range of emission violations and impose penalties that are equivalent to or exceed comparable federal penalties for the same violations.

The requirement for states to provide fo r adequate contingency plans to implement such authority is intended to estab lish emergency episode plans fo r responding to elevated pollutant levels in urban areas. Emergency episode plans are required in areas that record pollutant concentrations in excess of threshold levels specified in 40CFR51.150. U.S. EPA is proposing to amend this regulation to address new ozone and PM 2.5 standards.

ARB commits to submit any necessary revi sions to its Air Pollution Emergency Plan upon adoption of amended guidance by U.S. EPA.

§ 110(a)(2)(H) SIP Revisions For Revised Air Quality Sta ndards Or New Attainment

Methods

States are to provide for revision of SIPs fr om time to time when air quality standards

are revised or new attainment methods bec ome available or when U.S. EPA informs

states that current SIPs ar e inadequate to attain standards or to comply with additional requirements under the Clean Air Act.

ARB is submitting a revised SIP that res ponds to revised and new air quality standards

for both 8-hour ozone and PM2.5.

ARB commits to submit SIP revisions w henever revised air quality standards are promulgated by U.S. EPA.May 7, 2007 Appendix B 6 § 110(a)(2)(I) SIP Revisions fo r New Nonattainment Areas

States are to submit SIP revisions for newly designated nonattainment areas to meet the requirements of Part D - Plan Require ments for Nonattainment Areas under Clean

Air Act Title I - Air Pollution Prevention and Control. Part D of the Clean Air Act specifies both general requirements for all SI Ps and specific requirements for different criteria pollutants. ARB ma intains all SIP documents at: http://www.arb.ca.gov/p lanning/sip/sip.htm

.

ARB commits to submit SIP revisions wheneve r areas of the state are newly designated nonattainment for any federal ambient air quality standard.

§ 110(a)(2)(J) Consultation and Public Notification

States are to meet the applicable requirements of CAA Section 121 (relating to consultation), Section 127 (relating to pub lic notification), and Part C (relating to prevention of significant deter ioration (PSD) of air quality and visibility protection).

Section 121 requires that stat es provide a satisfactory pr ocess of consultation with general purpose local governments , designated organizations of elected officials of local governments, and any affected federal land manager in carry ing out CAA requirements.

California Health and Safety Code Section 41650 et seq requires ARB to conduct public hearings and to solicit testimony from air di stricts, air quality planning agencies, and the public when adopting local nonatta inment plans for inclusion in the SIP. Additionally,

the California Administrative Procedures Ac t, Government Code Section 11340 et seq, requires notification and provis ion of comment opportunities to all parties affected by proposed regulations.

ARB commits to maintaining a process of consultation with parties designated under

Section 121.

Section 127 requires the states to provide m easures which will be effective to notify the public on a regular basis of instances or areas in which any air quality standard is exceeded during the preceding cal endar year, to advise the publ ic of the health hazards associated with such pollution, and to enhance public awareness of measures that can be taken to prevent such standar ds from being exceeded.

California Health and Safety Code Section 39607 requires ARB to implement a program for securing air quality data in each air bas in and reporting these data to the public. ARB maintains these air quality data and the other information requi red by Section 127 on its website, which is conti nuously available to the public. 1

, http://www.arb.ca.gov/research/health/health.htm

, http://www.arb.ca.gov/html/cando.htm , viewed on February 1, 2007.May 7, 2007 Appendix B 7 ARB commits to maintaining a public info rmation and education program that satisfies the requirements of Section 127.

Many air districts in Californi a have adopted regulations for the prevention of significant deterioration (PSD) that have been approved by U.S. EPA. In those areas where approvable regulations have not been adopted, U.S. EPA enf orces PSD requirements through a federal stationary source pe rmitting program under enabling authority prescribed by 40CFR52.21.

ARB commits to ensuring that PSD regul ations are implement ed in California.

§ 110(a)(2)(K) Air Quality Modeling and Reporting

States are to provide for the use of air quality modeling to pr edict the effect of emissions on ambient air quality and to submit data rela ted to such modeling when requested by

U.S. EPA.

ARB’s air quality modeling work complies with U.S. EPA’s final guidance on the use of

models in attainment demonstrations for the 8-hour ozone standard and uses U.S. EPA’s latest draft final guidance for model ing PM2.5. This is a rapidly-evolving

field in which ARB endeavors to use t he latest methodology and techniques, and

documents information that its staff uses when conducting modeling or when evaluating the performance of air quality models used for this purpose. ARB consults and works closely with local districts that conduc t their own regional air quality modeling.

ARB provides air quality modeling softwar e and documentation with links to databases and search engines at http://www.arb.ca.gov/h tml/soft.htm#modeling

.

ARB commits to continue to use air quality models in accordance with both U.S. EPA and ARB’s currently approved modeling guidance and protocol s and the continued submittal of data and modeling results to U.S. EPA.

§ 110(a)(2)(L) Major Stationa ry Source Permitting Fees

States are required to assess the owner or operator of ea ch major stationary source

with fees sufficient to cover the reasonable costs of reviewing and acting upon any application for such a permit, and if a pe rmit is granted, the reasonable costs of implementing and enforcing the terms and c onditions of the permit. Owners or operators are also required to comply with the fee provisions of Title V Sections 501 –

507 of the Clean Air Act. Such fees are required to be payable to the permitting authority.

As noted above, responsibility to issue permits for stationary sources of air pollution is vested with the local air districts, and eac h air district in California has adopted regulations that require an addi tional fee for facilities subject to Title V requirements.May 7, 2007 Appendix B 8 Information concerning thes e permits issued by local air districts is found at http://www.arb.ca.gov/permits/airdisop.htm and http://www.arb.ca.gov /permits/permits.htm

.

ARB commits to continue to implement dist rict-adopted major stationary source permit fee regulations.

§ 110(a)(2)(M) Consultation with Local Entities

States are to provide for consultation and part icipation by local political subdivisions affected by the plan.

California is divided into loca l air districts, which are county or regional local government authorities that have responsibil ity for controlling air pollution from stationary sources. A map of the local air districts showing boundaries for each district is found at http://www.arb.ca.gov/capcoa/dismap.htm . Links to the local air districts’ web sites can

be found at http://www.arb.ca.gov/capcoa/roster.htm

.

ARB consults with and provides liaison with all local air districts and provides frequent and regular communication and consultation with management and staff of local air

districts. Since local air di strict boards are composed of local elected officials, this provides for the regular consultation and par ticipation with local government entities (cities and counties) affected by the SIPs. California Health and Safety Code Section 41650 et seq requires the ARB to conduct public hearings and to solicit testimony from air districts, air quality planning agenc ies, and the public when adopting local nonattainment plans for inclusion in the SIP.

ARB commits to maintaining a consultation process with local political subdivisions affected by the SIP.

Sections 110 (a)(1) and (2) of the Clean Air Ac t require states to submit SIPs that implement, maintain, and enforce a new or revised national ambient air quality standard within 3 years following promulgat ion of the standar d. Among the SIP

elements identified in Sect ion 110(a)(2) is the r equirement to address the transport of pollutants between states. Th is section also requires states to

ensure that their SIP does not interfer e with another state’s program to prevent significant deterioration of it s air quality or interfere with vi sibility in another state.

In April 2005, the U.S. EPA notified states of their fa ilure to make the required SIP submission addressing interstate trans port of pollutants related to ozone and PM2.5. This “failure to submit” finding for the required inters tate transport SIPs

started a 24-month clock for U.S. EPA to issue a final Federal Implementation Plan (FIP) for any state that does not subm it a plan within that time period.

On August 15, 2006, U.S. EPA issued guidance for submitting interstate transport or “Good Neighbor” SIPs. In accordance with that guidance, this

document contains documents the fi ndings that California meets the requirements of sections 110 (a)(1) and (2) of the Clean Air Act for both the

federal 8-hour ozone standard and t he federal PM2.5 standard.

Closest Nonattainment Areas to California

Ozone : The closest 8-hour ozone nonattain ment areas are Las Vegas, Nevada, and Phoenix-Mesa, Arizona.

PM2.5 : The closest PM2.5 nonattainment area is Libby, Montana. Libby is more than 900 miles away from the San Joaquin Valley, the nearest PM2.5

nonattainment area in California.

Evaluation of significant contribution to nonattainment or interference with

maintenance of attainment standards in another state

U.S. EPA did an analysis for its Clean Air Interstate Rule or CAIR to identify

states that were contribut ing significantly to nonattain ment of PM2.5 and ozone in adjacent states. In the preamble to that rule, U.S. EPA stated that:

“In analyzing significant cont ribution to nonattainment, we

determined it was reasonable to exclude the Western U.S., including the States of Wash ington, Idaho, Oregon, California

, Nevada, Utah and Arizona from fu rther analysis due to geography, meteorology, and topography. Ba sed on these factors, we

concluded that the PM2.5 and 8-hour ozone nonattainment problems are not likely to be affected significantly by pollution transported across these States’ boundaries. Therefore, for theMay 7, 2007 Appendix C 2 purpose of assessing State’s cont ributions to nonattainment in other States, we have only analy zed the nonattainment counties

located in the rest of the U.S.” 1 (emphasis added)

The meteorological discussions below provide more detail.

Ozone : Ozone episodes over the Southwes tern United States are normally associated with strong high pressure systems centered over the Southwest Desert. These meteorological patterns are characterized by clear skies, warm temperatures, and light winds and result in very stagnant conditions over the region. Ozone is not transported over long distances under these conditions. On occasion, the strong high pressure is weak ly impacted by migrating low pressure systems over the Pacific Ocean. This has the dual effect of maintaining stagnant

conditions over most of t he region while allowing weak pressure systems to push air that is high above the surface eastwar d and to transport ozone trapped in this layer over long distances.

PM2.5 : The technical support document for the PM2.5 designation of Lincoln County, Montana (containing Libby, Montana) found that the nonattainment area

is “localized within and around the vici nity of the town of Libby due to topographical features and meteorology in the area impacted by emissions.” Therefore, Libby, Montana’s nonattainment status is not affected by emissions produced in other areas and transported to the Libby area.

U.S. EPA’s conclusion in CAIR pream ble plus the above meteorological summary support the finding that Californ ia does not significantly affect

nonattainment areas in other states.

California’s existing stringent motor v ehicle control program, consumer product regulations, stationary source permitting, new source review programs, and new

commitments outlined in the Californi a SIP further strengthened by the 8-hour ozone and PM2.5 SIPs will result in steadily decreasing emissions. This greatly

reduces the likelihood that emissions from California will contribute significantly to nonattainment in any downwind state.

U.S. EPA guidance 2 for interstate transport SIPs advises states to make a SIP

submission to confirm that major sources in the Stat e are currently subject to prevention of significant deteriorati on (PSD) and nonattainment new source review (NNSR) preconstruction permitti ng programs that apply to the 8-hour

ozone standard.

For the PM2.5 standard, the guidance adv ises states to provide a SIP

submission to confirm that major sources in the Stat e are subject to PSD and NNSR permitting programs impl emented in accordance wit h U.S. EPA’s interim guidance calling for use of PM10 as a su rrogate for PM2.5 in the PSD and NNSR

programs.

In California, all areas are subject to some form of preconstruction program for

ozone and PM2.5. These rules are as stringent, or more stringent, than the federal preconstruction progr ams (PSD and NNSR). For ozone, California is on track to submit SIPs per the Phase II 8-hour Ozone Implementation Rule. For PM 2.5, California’s preconstructi on programs are being implemented in accordance with EPA’s interim guidance calling for the use of PM10 as a surrogate for PM2.5 emissions.

The following air districts are in atta inment of the feder al 8-hour ozone and PM2.5 standards and have a SIP approved PSD rule.

• Mendocino County Air Pollution Control District

• Monterey Bay Unified Air Pollution Control Dis trict

• Northern Sonoma County Air Pollution Control District

• North Coast Unified Air Quality Management District

• Sacramento Metro Air Quality Ma nagement District (PM2.5)

On a case-by-case basis, U.S. EPA has delegated partial PSD permitting authority to the following air districts that are in attainment of the federal 8-hour

ozone and PM2.5 standards.

• Antelope Valley Air Quality Management District

• Bay Area Air Quality Management District

• San Diego Air Pollution Control District

For all other areas that are in attainm ent of federal standar ds, U.S. EPA retains federal PSD permitting authority.

U.S. EPA’s guidance 3 states that states and region al planning organizations are currently engaged in the task of identif ying Class I areas impacted by each state’s emissions and developing strategi es for addressing regional haze to be included in the States’ regi onal haze SIPs. Since thes e regional haze SIPs are not due until December 17, 2007, states will not be r equired to address this requirement until the Regional Ha ze SIPs are submitted.

California is on track to submit its R egional Haze SIP by December 17, 2007. The Regional Haze SIP will address interstate regional haze impacts.

### Appendix D

Reasonable Further Progress a nd Contingenc y Reductions(This page intentionally left blank.)May 7, 2007 Appendix D 1 Introduction

Reasonable further progress (R FP) refers to the annual emi ssion reductions required to demonstrate continued and steady progress toward attaining air quality standards. A

SIP must demonstrate both RFP and attainment to be approvable. It must also include contingency emission reductions that must be achieved if a nonattainment area fails to

meet certain milestones. The RFP r equirements for the 8- hour ozone standard are described in the “Final Rule to Implement the 8-Hour Ozone National Ambient Air Quality Standard,” and build upon the requirement s specified in Clean Air Act sections 172(c)(2), 182(b)(1) and 182(c)(2)(b).

This appendix will summarize how Californi a meets its RFP and contingency reduction requirements. It is impo rtant to note that the requirements are met in every nonattainment area with already-adopted meas ures. No new emission reduction commitments are required and no reductions fr om the State Strat egy’s proposed new

measures are needed to m eet the requirements.

RFP Requirements

RFP requirements vary by nonattainment classi fication. The following is a discussion about RFP requirements for California nonattain ment areas as initially designated by

U.S. EPA.

Areas with a basic classification that can at tain the standard within the first five years after the designations become effective (2004-2009) do not hav e to demonstrate RFP. Three basic areas, Sutter Buttes, Butte County and San Diego County will meet the federal standard by 2009. Areas with a marg inal classification – Imperial County and San Francisco Bay Area – are not s ubject to RFP requirements.

Moderate and basic areas that require more t han five years to attain must demonstrate

RFP. Their RFP demonstrations include an initial 15 percent reduction in ROG and/or

NOx emissions from the 2002 baseline ROG inventory by 2008. They then must achieve additional reductions per year, aver aged across each consecutive 3-year period or part thereof until their atta inment year. Basic areas needi ng additional time to attain include: Eastern Kern, Sout hern Mountain Counties, Cent ral Mountain Counties, and Western Nevada County. Moderate areas include: Ventura, Antelope Valley and Western Mojave Desert.

Areas whose 1-hour ozone rate of progress plans were not approved by the U.S. EPA are subject to different RFP requirements. These areas still must meet the initial RFP target of 15 percent ROG reductions for the first six years (2002-2008), as set forth in Clean Air Act section 182(b)(1). They cannot use NOx emission reductions to satisfy the initial target when ROG emissions are not sufficient. The area s subject to this restriction are Coachella Valley, Antelope Valley, and Western Mojave Desert, which comprise the former Southeast Desert 1-hour ozone nonattainment area. This presents a challenge for the former Southeast Desert areas because their nonattainment status is due in part to pollution transported from the South Co ast. In such situations,May 7, 2007 Appendix D 2 U.S. EPA allows the nonattainment area to account for emissi ons occurring, and emission reductions achieved, in upwind areas to be credited towards rate of progress. With transport included in the calculation, the Coachella Valley meets rate of progress requirements.

For RFP, nonattainment areas classified serious and above must demonstrate an 18 percent reduction in ROG and/or NOx emissions from the 2002 baseline ROG inventory by 2008. In the years that follo w, they must demonstrate, on average, an additional 3 percent per year reduction in ROG and/or NOx emissions until their attainment year. Serious areas are: San Joaquin Valley, Coachella Valley and

Sacramento. Note that for the reasons given above, Coachel la Valley is subject to a 15 percent ROG-only reduction requirement from 2002 to 2008. The South Coast Air

Basin is classified as severe.

For moderate and above 8-hour ozone nonattain ment areas, a limit ed amount of NOx reductions may also be used, to a point, as a substitution for ROG reductions for RFP.

NOx emission reductions creditable toward th e RFP requirement cannot be greater than

the cumulative NOx reductions that are nece ssary to demonstrate attainment. This attainment consistency requirement is m eant to prevent the substitution of NOx reductions for progress purposes that w ould not lead toward attaining the ozone

standard.

U.S. EPA has taken the position in guidanc e, and not in regulation, that for nonattainment areas classified under Subpar t 2, reductions needed for progress in the attainment year should equate to those needed for attainment. ARB staff disagrees. We believe a plain reading of the Act indica tes that a 3 percent reduction per year is needed between the next-to-last milestone year and the attainment year . For example, in a severe-15 area, the next-to-last milest one year is 2017 and the attainment year is 2018. A 45 percent reduction is needed in 2017 for RFP. Therefore, the RFP requirement for the next year (2018) is thre e percent more, or 48 percent – and not the

reductions needed for attainment.

Upwind Emissions in RFP Demonstrations

Ozone levels are influenced by ROG and NO x emitted both within a nonattainment area and transported from upw ind locations. U.S. EPA acknowledges this relationship by allowing emission reductions from upwind lo cations outside the nonattainment area to be included for RFP, up to 100 kilometers for ROG and 200 kilometers for NOx.

The inclusion of transport contributions of ROG and NOx provides key emission reductions in RFP analyses for the following nonattainment areas: Antelope Valley and Western Mojave Desert, Central Mountain C ounties, Coachella Valley, Eastern Kern,

Southern Mountain Counties and Western Nevada. Their em ission inventories for RFP purposes include ROG and NOx emissions from counties that are (1 ) entirely within the designated 100km and 200km distances, and (2) part of the area’s established federally-approved transport couples.

Federal Motor Vehicle Control Program AdjustmentsMay 7, 2007 Appendix D 3 Section 182(b)(1)(D) of the Cl ean Air Act stipulates that emission reductions stemming

from the federal on-road motor vehicle control program as it existed in 1990 may not be used to help meet minimum emission reducti on requirements for RF P purposes. This precludes states from securing the em ission reductions required to demonstrate satisfactory progress for ozone simply on the merit of the federal motor vehicle control program as it existed in 1990. The Clean Air Ac t also prohibits states from taking credit for emission reductions resulting from using gasoline with a Reid vapor pressure limit specified by 1990. States are required to adjust for the benefits of these federal programs in RFP calculations. ARB staff ha s considered the combined benefits of the federal motor vehicle and fuel volatility programs for purposes of this discussion, and

will reference them below as the “federal program” and “federal program adjustments”.

California’s pioneering efforts to set emission standards from motor vehicles resulted in

nationwide emission standards adopted by U.S EPA. In general, California’s auto emission standards have been, and are, mo re stringent than f ederal standards, particularly for passenger vehicles.

In analyzing what federal program adj ustments should be made to California nonattainment area RFP reductions, ARB st aff analysis concluded that the federal program did not provide any additional benefits beyond Califo rnia’s program and that the federal program adjustment in all nonattainment areas should be zero. This is a bit different than the rate of pr ogress reductions for the last 1-hour ozone SIP, where some federal program adjustments we re made. ARB staff’s met hodology for calculating the federal program benefits remain s unchanged, except to refl ect a change in the baseline year from 1990 (for 1-hour ozone plans) to 2002.

California’s on-road control program has continued to advance since 1990, so

emissions from motor vehicles in 2002 ar e much lower than they were in 1990. Additionally, large increases in vehicle miles traveled from 1990 to 2002 result in a higher-emitting federal fleet for 8-hour ozone RFP than for the 1-hour ozone rate of progress. Combined, these factors lead to the conclusion that the pre-1990 federal program provides no benefits to Ca lifornia in 8-hour ozone RFP plans.

Contingency Requirements

Contingency reductions are to take effect without further ARB or air district action if the

nonattainment area does not achieve an RFP mile stone, or if the area does not attain

the federal 8-hour ozone or PM 2.5 standard at the end of th eir identified attainment year. This requirement does not apply to marg inal nonattainment ar eas, only to basic, moderate, serious, severe and extreme areas (for RFP only). Since these contingency

reductions must be achieved without further action, U.S. EPA has interpreted this to mean that the contingency reductions must be from measures that have already been adopted when the submittal is made (or possi bly prior to U.S. EPA taking action).

The bulk of emission reductions needed to attain the federal standards in this submittal are achieved through regulations that make up California’s mobile source emission control program, which has been very successf ul in reducing emissions within CaliforniaMay 7, 2007 Appendix D 4 and represents the foundation s upporting attainment of both federal and State ambient air quality standards. ARB has a well est ablished history of adopting and implementing mobile source control regulations on time or earlier than it has committed to do so. As a result, we expect to achieve, and even exceed, our RFP goals without the need for contingency reductions.

For all nonattainment areas , already-adopted measures provide more emission

reductions than are needed to meet RFP r equirements in every milestone year. Therefore, the emi ssion reductions from adopted measur es that go beyond the RFP requirements will constitute the contingency r eductions in the unlikely event that the

State does not meet the RFP goals.

Failure to meet federal air quality standar ds is determined by monitored air quality values in the attainment year, and is therefore determined a fter the end of the attainment year. California's motor vehicl e emission control program allows ARB to provide additional emission r eductions each year, based on the increasing benefits of measures that are already bei ng implemented. Therefore, ARB proposes to include the

benefits of one additional year of its ongoing motor vehi cle program, including vehicle fleet turnover, and light-duty vehicle inspec tion and maintenance in the year following each area’s attainment year.

Contingencies for new technologies

In terms of contingency for a ttainment, additional provisions apply to extreme areas that include new technologies in their attainment plans. These attainment demonstration plans can rely on future advances in emissi on reduction technologies (referred to as new technologies) if the State, among other things, submits enforceable commitments to develop and adopt contingency measures if the anticipated technologies do not achieve the planned reductions, and if the St ate demonstrates that the contingency reductions shall be adequate to achieve atta inment and reasonable further progress.

These contingency reductions to back-up the new technology provisions are not due until three years before implementation of these new technology provisions. The need for technology development and long-term measur es, as well the process for identifying long-term emission reductions is discussed in Chapter 3.

Reasonable Further Progress and Contingency Demonstrations

The following descriptions for each nonattain ment area outline California’s RFP and related contingency reductions demonstrati ons. Since already-adopted measures provide all contingency reductions needed for RF P and attainment, the requirement that reductions will occur without any further action by ARB or local air dist ricts is fully met.

ARB staff reports for each nonattainment area will include demonstration of RFP and contingency reductions. Detailed charts providing the background for RFP and contingency reductions for South Coast, San Joaquin Valley, and Coachella Valley, can be found on pages 6-8 of this appendix. All three of these areas are expected to request a change in their nonattainment classifi cations – extreme for both South CoastMay 7, 2007 Appendix D 5 and San Joaquin Valley and severe-15 for Coac hella Valley. The charts reflect the anticipated nonattainment classifications.

South Coast

The South Coast meets its RFP targets through 2014 purely on the basis of ROG reductions from the existing control program. From 2017 fo rward, the South Coast will

need to use both ROG and NOx reductions fr om the existing control program. Reductions from proposed new measures are not needed to achieve the progress targets.

Adopted measures in the South Coast Ai r Basin are expected to yield enough

reductions to meet the RFP goals and will also yield a su rplus that will meet the contingency reduction require ments for the area.

San Joaquin Valley

The San Joaquin Valley meet s its RFP targets through bot h ROG and NOx reductions from the existing control pr ogram. Reductions from prop osed new measures are not needed to achieve the progress targets.

Adopted measures in the San Joaquin Vall ey are expected to yield enough reductions to meet the RFP goals and will also yield a surplus that will meet the contingency reduction requirements for the area.

Coachella Valley

Because the Southeast Desert 1-hour oz one nonattainment area did not have a federally-approved progress plan, the Coac hella Valley’s 8-hour RFP plan must demonstrate a 15 percent emission reduction from 2002 to 2008 by relying only on ROG reductions. The area meets this require ment. Expecting the South Coast District to request a bump up to the severe -15 classi fication for the Coachella Valley, progress is calculated through 2018. Upwind emi ssions of ROG have been used from Orange County, the portion of San Be rnardino County within the South Coast Air Basin, and the portion of Riverside County within South Coas t Air Basin. Upwind emissions of NOx

from these counties an d Los Angeles County hav e also been included.

Adopted measures in the Coachella Valley are expected to yield enough reductions to meet the RFP goals and will also yield a surplus that will meet the contingency reduction requirements for the area.May 7, 2007 Appendix D 6 Detailed Analysis of South Coast Reasonable Further Progr ess and Contingency (summer planning, tons per day)

### Appendix E

Potential Impacts of State Str ategy Proposed New Measures(This page intentionally left blank.)May 7, 2007 Appendix E 1 ENVIRONMENTAL IMPACT ANALYSIS

Introduction

The control measures proposed in the St ate Strategy were developed for the purpose of improving air qualit y in California. However, as these measures are developed into rules and regulations and subsequently implemented, there is potential for them to have an adverse environmental impact on other natural

resources. The Californi a Environmental Quality Ac t (CEQA) and ARB policy requires an analysis to determine any pot entially adverse environmental impacts that may result from adopt ion of these measures. This appendix presents an analysis of potential impacts and also identi fies mitigation measures that can be implemented to offset any potentially si gnificant impacts. The appendix contains three parts: an environmental review checklist, descriptions of cumulative impacts of the State Strategy, and a de scription of each measure’s potential adverse environmental impacts.

California Environmental Quality Act

The California Secretary for Resource s has determined t hat ARB meets the

criteria for a Certified St ate Regulatory Program (Pub lic Resources Code Section 21080.5). This certification allows AR B to adopt rules, regulations, standards and plans but exempts it from the requirement to prepar e Initial Studies, Notices of Preparation, Negative Declarations or Environmental Impact Reports (EIRs). As a certified agency, however, ARB is required to prepare a substitute document which is subject to other pr ovisions of CEQA such as avoiding significant adverse effects on the envir onment where feasible. This appendix considers cumulative impacts and addresses adverse activities and impacts associated with the proposed measures. As required by CEQA, there will be a 45-day public comment period at which time the public can review and comment on this analysis. ARB will respond in wr iting to all significant environmental concerns raised by the public during this comment period and also at the Board Hearing.

Scope of Analysis

The scope of the analysis is intended to help focus public review and to assure that any questions and comments are appropriate and meaningful. This appendix specifically focuses on potential adverse environmental impacts. The remainder of the report emphasizes pos itive environmental benefits that the proposed strategies will have on air quality which is the purpose and goal of the State Strategy.

This appendix cannot and does not cont ain a detailed, quantitative impact analysis for each of the control measures in the State Strategy. Because the State Strategy identifies proposed fu ture actions to adopt and implementMay 7, 2007 Appendix E 2 emission reduction regulations for which specific regulatory language has not yet been developed, the analysis is necessarily general and qualitative. When a proposed measure is developed and proposed in regulatory format, it will be a process with full public participation. Proposed regulations will undergo a detailed environmental analys is as required by CEQA, will be discussed at public workshops, and will go through the public hearing process as required by law (see the Administrative Procedure Act, Go v. Code section 11340 et seq.). When specific regulatory language is developed, it will be possible to analyze potential environmental impacts in detail. For example, the scope of the impacted population of any given c ontrolled emission source will become further refined during regulatory development. Additi onally, cumulative impacts were

considered for the State St rategy, recognizing these measures are likely to have various phase-in dates. In this a ppendix, potential environmental impacts are identified to the extent currently feasible.

Environmental Checklist

An environmental checklist was us ed to identify and evaluate potential cumulative impacts of the measures proposed in the State Strategy. The

environmental effects checked below indicate those that may be affected by the proposed measures. Further discussion w ill follow regarding the impacts that strategies may have and potential mitigatio n strategies that can be implemented to lessen the impacts.

Each environmental effect outlined in the environmental checklist is further

described below. A detailed reference tabl e at the end of this section identifies each measure in the State Strategy , any potential adverse environmental impacts, and potential mitigation measures.

Several proposed measures are currently in the process of rule development and may have a more detailed assessment of po tential significant impacts. However, for the less developed strategies, we have attempted to include any potential impact that reasonably could occur given current knowledge.

I. Aesthetics

Cumulative Impact: No elem ent of the State Strategy is expected to degrade the natural beauty of California. Instead, the State Strategy will have significant positive impacts on aestheti cs. Regional haze is expected to be reduced by State Strategy elements that reduce hy drocarbon, nitrogen oxide, and particulate

matter emissions.

II. Air Quality

Cumulative Impact: ARB staff believe s the cumulative impact of the State Strategy is to substantially improve air quality, however there are potentially significant impacts to air quality. Some strategies may involve trade-offs, where emissions of one pollutant may increase sl ightly in order to more effectively reduce overall emissions and protect public health.

The four major types of impacts that we re considered are related to criteria pollutants, air toxics, greenhouse gas es, and stratospheric ozone depleting pollutants.

Criteria Pollutants

Potentially significant impacts on criter ia pollutant emissions may occur due to: selective catalytic reduction processes, use of diesel part iculate filters, and production and consumption of lo w-sulfur diesel fuel. However, the cumulative impact of the State Strategy is to reduc e emissions of major criteria pollutants (ROG, NOx, SOx, and PM2.5).

Selective Catalytic Reduction

— Measures in the State Strategy to reduce NOx from diesel-fueled engines may necessitate use of Selective Catalytic Reduction (SCR). For on-road heavy-duty diesel vehicles in particular, SCR is the preferred emission control strategy for meeting the NOx emission r equirements for the 2010 model year. The use of SCR in light -duty diesel vehicles is also being considered by auto manufacturers. S CR reduces NOx into molecular nitrogenMay 7, 2007 Appendix E 15 and water by injecting urea into the ex haust upstream of a catalyst. SCR catalysts function well only within a na rrow temperature win dow, and control systems must be in place to keep the ex haust temperature within an optimum range. If exhaust temperatures ar e too high, the SCR catalyst can be deactivated or fail. If exhaust temperatur es are too low, or too much reductant (usually urea) is used, ammonia can become an exhaust byproduct (called “ammonia slip”) and can be emitted to t he atmosphere. Ammonia slip can worsen as the catalyst ages and becomes less effective.

Diesel Particulate Filters — A number of measures in the State Strategy would require the use of diesel particulate f ilters, add-on devices that are mounted on the exhaust pipe. Certain types of these di esel particulate filters, referred to as passive filters, accelerate the conversion of nitric oxide (NO) to nitrogen dioxide (NO 2 ). As such, there is a potential for an adverse effect on the concentration and location of peak ozone levels in the St ate, especially near centers of diesel activity.

Catalyst manufacturers are aware of the issue, and preliminary analysis suggests that the impacts may be mitigated by desig ning the system to limit the NO to NO 2 conversion rates. In the near term, the advantages of pu tting diesel particulate filters into operation to reduce risk from diesel PM and allowing the technology to develop and mature should offset any limited adverse impacts.

Reformulated Gasoline — The purpose of this strategy is to offset or eliminate excess evaporative emissions caused by ethanol permeation through fuel lines and tanks. Reformulating gasoline may require more feed stock and/or more processing which means that impacts a ssociated with this measure could come

from an increased demand on refineries. However, air district permitting programs will evaluate and mitigate the air quality and environmental impacts to

the extent feasible.

Cold Ironing (Shore-side Power) — This process allows ships to run heating, air conditioning, lights and other operations by plugging into shore-side electrical power. This reduces emissions by allo wing ships to shut down the uncontrolled auxiliary engines which traditionally have po wered these electric-based activities. There are criteria pollutant emissions associated with t he incremental electricity generation from power plants, but they are significantly less than emissions generated by ship engines.

Low Sulfur Diesel Fuel — Low sulfur diesel f uel requires increased hydrotreating of fuel to remove sulfur, which requires increased hydrogen production. Hydrogen production, from petro leum feedstock, has the potential to increase criteria pollutant s (particularly NOx) and CO 2 emissions. The most acute impact of any emissions increas e could be in the communities near refineries, however, air di strict permitting programs will evaluate and mitigate the air quality and environmental impac ts to the extent feasible.May 7, 2007 Appendix E 16 Electrification of Equipment — Electric forklifts, do ckside electrical hookups for larger marine vessels, and other strategies may incrementally increase electricity demand from power plants. The incr ease in power production will have an incidental increase in emissions (primarily NOx) from power plants. Air district permitting programs are in place to limit these emission increases. Overall, emissions should decrease significantly as fuels such as diesel and propane are replaced by the much cleaner natural gas burned at well-controlled power plants.

Locomotives — Diesel oxidation catalysts (DOCs) operating under high loads and temperatures can increase SO2 to SO 4 formation. Locom otives fueled out

of state will use non-road dies el fuel with sulfur levels lowered from 5,000 to 500 ppmw on June 1, 2007. However, since most refueling for inte rstate locomotives occurs in-state, and locomotives in Californi a typically use ultra low sulfur diesel (<15 ppmw), this is not a significant source of SOx. SOx is emitted in direct proportion to the diesel fuel sulfur content.

Vehicle Retirement Program — Scrapping retired vehicles involves the use of heavy-duty equipment to crush vehicles and then transport the recyclable

materials to markets whic h often times are located overseas. The increased processing and transport of the scrapped materials could create additional emissions, however, the State Strategy also includes measures to reduce emissions from ships and heavy-duty off- road equipment. The benefit of retiring high-polluting vehicles greatly outweig hs the emissions from processing.

Air Toxics

Potentially significant air toxics impacts could occur due to reformulation of consumer products and the use of alternativ e fuels, alternative fuel additives and alternative aftertreatment systems. Ho wever, any new formulations of these products and additives would be closely scr utinized to prevent the addition of toxic compounds. These potential impac ts will be greatly offset by the

substantial reductions in toxics from diesel engines required by the State Strategy. The cumulative impact of the State Strategy is to greatly reduce emissions of toxic compounds. A brief description of potentia l impacts of the strategies is provided below.

Selective Catalytic Reduction — Since SCR technology represents a significant departure from conventional emission controls deployed on motor vehicles, there is the potential for thes e systems to emit new toxic substances that have not been readily observed in previous studies, and/or exhibit an increase in some currently emitted toxic substances due to urea-related chemistry. Such seco ndary emissions are likely to include organonitrogen compounds, many of which are listed as toxic air contaminants (TAC) and are carcinogenic.May 7, 2007 Appendix E 17 Vehicle Retirement Program — High-mileage and older vehicles are likely candidates for scrappage. Their deterio ration leads to increased emissions. Once vehicles are scrapped, they can no longer pollute. However, vehicles commonly contain lead, chromium and mercury which may be released during the scrapping process. These toxic ai r pollutants have potential to have an adverse impact on air and water quality if not properly handled. For example, mercury switches used in hood and trunk lighting can be recovered rather than being crushed. Auto dismantlers are regulated by the D epartment of Toxic Substance Control (CCR, Title 22).

Cold Ironing (Shore-side Power)

— This process allows ships to run heating, air conditioning, lights and other operations by plugging into shore-side electrical power. This reduces emissions by allo wing ships to shut down the uncontrolled auxiliary engines which traditionally have po wered these electric-based activities.

There are toxic air contaminants asso ciated with increment al electricity generation at power plants, but they are significant ly less than emissions generated by ship engines.

Consumer Products

— The consumer products meas ures require reformulation

to reduce VOC content. A number of VO Cs currently used in consumer product formulations, such as ethylene-based glyco l ethers, trichloroet hylene (TCE), and toluene, have also been ident ified as toxic air contaminants. When a product is reformulated to meet new VOC limits, however, a manufacturer could use small amounts of a chemical, not us ed before, that may be a to xic air pollutant. This potential impact will need to be evaluated an d mitigated as reformulation options are reviewed during the development of new VOC limits, as staff has done in previous rulemakings.

Two particular toxic air contaminants (T AC) used in some consumer products, methylene chloride (MeCl) and perchloroethylene (Perc), are specifically exempted from the VOC definition becaus e of their very low ozone-forming capabilities. As a result, some manufac turers may choose to use MeCl or Perc

in their reformulations to reduce the VO C content in meeting future limits. However, when setting new VOC limits, staff analyzes the potential use of nonVOC TACs as reformulation options to ensure protection of public health. To avoid increased use of non-VOC TACs, st aff sets emissions standards that are commercially and technologically feasible without use of TACs or bans TACs in the category at hand. Staff has prohi bited three TACs—MeCl, Perc, and TCE— in approximately 56 categories to date, and will consider prohibiting their use in other categories, if feasible.

Cleaner Main Ship Engines — Various technologies can be used to reduce

NOx emissions from main sh ip engines such as low-NO x fuel injectors, delayed injection timing and technologies that add water vapor to the combustion chamber. Impacts associated with technolog ies include slight increases in PM,May 7, 2007 Appendix E 18 hydrocarbons and CO2. Additionally , there may be increased PM levels associated with selective catalytic reduction.

Fuel Additives — Fuel additives or reformulation of fuels may provide possible emission reduction benefits. However, f uel additives or fuel reformulation may

also create adverse emissions and environm ental impacts. Before a fuel additive or fuel reformulation is implemented as an emission reduction strategy, a

multimedia evaluation must be conducted under California Health and Safety

Code Section 43830.8. This evaluation wi ll assess the potential emission impact associated with any additive or fuel reformulation to the environment and public

health.

Greenhouse Gases

Potentially significant greenhouse gas emissi ons could result from measures that may reduce fuel efficiency or increase ener gy use, and consumer product rules.

Diesel-Fueled Engines — Proposed measures to reduc e emissions from dieselfueled engines could require the use of new diesel engines, engine modifications, add-on control devices such as diesel parti culate filters, ox idation catalysts and selective catalytic reduction (SCR) systems, lo w-sulfur diesel fuel , alternative fuel formulations, or other strategies. These strategies have the potential to slightly reduce fuel economy and incr ease greenhouse gas emissions. These impacts may be mitigated as other engine features become more effici ent to meet air pollution emission standards and by reduc ing idling times for trucks and other mobile equipment.

Diesel Particulate Filters — A number of measures in the State Strategy would require the use of diesel particulate filt ers. These particula te filters must be periodically regenerated by burning off t he accumulated carbon and associated hydrocarbons trapped on the filter. Acti ve regeneration met hods use external fuel or energy to heat t he filter and regenerate it.

Cleaner Main Ship Engines

— Various technologies can be used to retrofit main ship engines such as low-NOx fuel injectors, delayed injection timing and technologies that add water vapor to the combustion chamber. Impacts associated with technologies include slight increases in PM, hydrocarbons and

CO 2 . Additionally, there may be increased PM levels associated with selective catalytic reduction.

Consumer Products

— Alternative compounds used to meet lower VOC limits in the State Strategy’s consumer products meas ures could be greenhouse gases. For aerosol products to meet t he VOC limits in the proposed regulations, manufacturers may choose to replace so me or all of the typical hydrocarbon propellants, such as propane and butane, with the hydrof luorocarbons HFC-152a or HFC-134a, or carbon dioxide (CO 2 ), which are greenhouse gases. HFC-152aMay 7, 2007 Appendix E 19 and HFC-134a have no ozone depletion pot ential, do not contribute to the formation of ground-level ozone, are low in toxicity, and are less flammable. In addition, HFC-152a has the lowest global warming potential of all the HFCs and an atmospheric lifetime of only 1.5 year s. While HFC-134a has significantly higher global warming potential than HFC-152a, its use is quite limited. Because HFC-134a has such low flammability, it is typically only used in consumer product applications where flammability is a significant concern. Due to the high cost of HFC-152a and HFC-134a (as much as five to seven times greater than other hydrocarbon propellants, such as propane and butance), it is anticipated

that manufacturers will use as little HFC-152a or HFC-134a as possible when reformulating their aerosol products. Consequently, because these measures would not cause a significant increas e in the use of HFC-152a or HFC-134a, there would be a negligible global warmi ng impact. However, further analysis of the properties and effects of these HF Cs is needed. If the analysis reveals significant impacts, ARB staff would reassess the control strategy. CO 2 used as a replacement for hydrocarbon propell ants would be a recycled byproduct from existing processes and would not create an increase in global warming gases.

Stratospheric Ozone Depleting Pollutants

Consumer Products

— Some hydrochlorofluorocarbons are still used in a very small number of consumer products as solvent. HCFC-22 is also used as a blowing agent in some foam insulati on sealant products because of its low flammability. HCFCs are exempt VOCs under the existing and proposed regulations. It is unknown if there wil l be an increased use of these compounds in meeting lower VOC limits. However, all HCFCs are classified as group II ozone-depleting compounds by U.S. EPA and are scheduled for phase out by 2030. Because of the phase out, manufactu rers are very likely to use blowing agents and solvents other than HCFCs. We therefore anticipate that the impact on ozone depletion due to HCFCs will be negligible.

Vehicle Retirement Program — Auto dismantlers t hat receive end-of-life vehicles with air conditioning systems must remove any refrigerant contained in these systems. During the removal of t he refrigerant, there is potential for an

incidental amount of refr igerant to escape into t he atmosphere. Once the refrigerant is removed, it must be ta ken to a registered facility for proper handling.

III. Agricultural Resources

Cumulative Impact: The St ate Strategy is not expec ted to cause any adverse impacts on the agricultural resources of California. Ozone pollution causes significant crop yield loss in California. The State Strategy will help reduce ozone levels and consequently reduce crop loss resulting from ozone damage. A discussion of potential environmental impacts associated Department of Pesticide Regulation’s 2008 Pe sticide Element is at t he end of this section.May 7, 2007 Appendix E 20 IV. Biological Resources

Cumulative Impact: The St ate Strategy is not expec ted to cause any adverse impacts on the biological resources of Ca lifornia. We believe that the proposed measures will improve air quality and c onsequently, will improv e the habitat of our biological resources.

V. Cultural Resources

Cumulative Impact: The St ate Strategy is not expec ted to cause any adverse impacts on the cultural resources of Calif ornia. We believe that the proposed

measures will reduce ozone and acidic co mpounds in the air. Ozone, which causes oxidation, and airborne acids ar e both known to cause deterioration of archaeological, paleontologica l, and geological features.

VI. Energy Demand

Cumulative Impact: As energy demand in creases as a result of the State Strategy, there is a potential for signifi cant adverse environm ental impacts. These impacts can be mitigated through energy conservation programs, using renewable energy sources, and designi ng engine control syst ems to maximize

fuel efficiencies.

Several State Strategies involve electrific ation of equipment that could result in an increased demand for electricity most likely generated at power plants. In 2005, California produced 78 percent of its own electricity with the remainder imported. The total amount generated in-state came fr om natural gas (37.7%), coal (20%), large hydro-electric (17% ), nuclear (14.4%) and renewable energy sources (10.7%). In addition to incr eased electricity usage, some measures would require engine control devices that ca n reduce fuel efficiencies resulting in more fuel being used.

Reformulated Gasoline — Ethanol has about 30 percent less energy by volume than gasoline, therefore in creased ethanol in gasoline will decrease fuel economy by about 0.3 percent for each 1 percent of ethanol. Staff is investigating a change in the procedure for certifying al ternate formulations of reformulated gasoline that will lead to an in crease in the use of ethanol.

Cold Ironing (Shore-side Power) — This process allows ships to run heating, air conditioning, lights and other operations by plugging into shore-side electrical power. This reduces emissions by allo wing ships to shut down the uncontrolled auxiliary engines which traditionally have po wered these electric-based activities. This technology can significantly reduc e emissions from ship engines, however,

the trade off is an incremental increase in energy demand.May 7, 2007 Appendix E 21 Electrification of Equipment — Electric forklifts, dockside electrical hookups for larger marine vessels, and other strategi es may increase electricity demand from power plants. The increase in power pr oduction will have an incidental increase in emissions (primarily NOx) from power plants. Air district permitting programs are in place to limit these emission increases. Overall, emissions should decrease significantly as fuels such as diesel and propane are replaced by the much cleaner natural gas burned at power plants as well as including more renewable energy source s to the power mix.

Diesel Fueled Engines — Proposed measures to reduc e emissions from dieselfueled engines could require the use of new diesel engines, engine modifications, alternatively fueled engines, add-on control dev ices such as particulate filters and catalysts, low sulfur diesel fuel, alternat ive fuel formulations, or other strategies. These strategies have the potential to c ause a small decrease in fuel economy. Fuel economy impacts may be mitigated as engine design improves and engines operate more efficiently.

Diesel Particulate Filters — A number of measures in the State Strategy would require the use of diesel particulate filt ers. These particula te filters must be periodically regenerated by burning off t he accumulated carbon and associated hydrocarbons trapped on the filter. Acti ve regeneration met hods use external fuel or energy to heat t he filter and regenerate it.

Low Sulfur Diesel Fuel — Low sulfur diesel fuel requires increased hydrotreating of crude oil to remove sulf ur, which would requi re additional energy consumption.

VII. Geology/Soils

Cumulative Impact: The St ate Strategy is not expec ted to cause any adverse impacts on geology or soils.

VIII. Hazards and Hazardous Materials

Cumulative Impact: The purpos e of the State Strategy is to help California attain

the federal 8-hour ozone and PM 2.5 standards. ARB’s goal is to ensure that all individuals in California, especially child ren and the elderly, can live, work, and play in a healthy environment. Each of the measures in the State Strategy is

intended to reduce the health risks from air pollution. The measures would reduce the pollutants that contribute to adv erse health impacts, including: ozone, inhalable particles (including soot and dust), carbon monoxide, and toxic emissions (like particles emitted from diesel engines and benzene). There is a less than significant cumulative impac t that would result from proposed

measures.May 7, 2007 Appendix E 22 Several State and federal agencies current ly regulate hazardous and hazardous materials. A discussion of these regulat ions will follow Stat e Strategy potential impacts.

Consumer Products — In meeting lower VOC limits, t here is a slight potential that products may become more flammable if reformulation increases the use of highly flammable, exempt VOC solvents such as acetone and methyl acetate.

This could be of concern in the manufacture, storage, shipping and end use of the reformulated products. In many instances, howev er, manufacturers can use other, less flammable, exempt solvents and/or water borne formulations. It

should be noted that the VOCs that acetone often replaces are generally highly flammable as well. In addition, acetone is currently used in many consumer products without significant safety concer ns. Further, the U. S. Department of Transportation requires that c onsumer products meet specific criteria to ensure that there are no significant safety concerns with trans port and storage of the products.

Selective Catalytic Reduction (SCR)
— Selective catalytic reduction is likely to be used on heavy-duty diesel engines to r educe NOx in the exhaust. Urea is the preferred reductant used to react with the NOx, in the presence of a catalyst, to form nitrogen gas and water. The use of ammonia as a reductant in motor vehicle-based SCR systems is very unlikely.

Fuel Additives and Reformulation
— Before proposing rules requiring fuel reformulations, staff must conduct a mu ltimedia evaluation as required under California Health and Safety Code Secti on 43830.8. This evaluation will assess the potential impact associated with any f uel reformulation to the environment and public health including worker exposure.

Diesel Particulate Filters
— A number of measures in the State Strategy would require the use of diesel particulate f ilters. Some safety concerns include reduced visibility from the driver’s seat due to new equipment mounted near eye level, particularly on off-road equipment such as bulldozers, backhoes, and

tractors. ARB staff be lieves that proper engineeri ng design can mitigate or eliminate these pot ential problems.

Diesel particulate filters must be regenerated by burni ng off the accumulated carbon and associated hydrocarbons tr apped on the filter. Active regeneration methods use external fuel or energy to heat the filter and regener ate it. A slight potential exists for a runaway regeneration that could pose a fire hazard. Proper engineering design should mitigate or e liminate these potential risks. Diesel particulate filter measures will be writt en to assure that the design is proven

effective.May 7, 2007 Appendix E 23 Idling Inspections

— Increased idling at inspection stops for heavy-duty diesel will expose people involved with or performi ng the inspections to toxic diesel PM emissions. Diesel engines emit a complex mix of pollutants, t he most visible of which are very small carbon particles, or ‘soot’ known as diesel PM.

Power Plants — Increased energy required from power plants may be a source

of localized releases of toxic air cont aminants causing exposure to workers and nearby residents.

Hazardous Materials

Hazards are related to the risks of fire, explosions, or releases of hazardous

substances in the event of accident or upset conditions. Hazards are thus related to the production, use, storage, and transport of hazardous materials. Industrial production and processing fac ilities are potential sites for hazardous materials. Examples of hazardous mate rials used by consumers include fuels, paints, paint thinner, nail polish, and solvents. Hazardous materials may be stored at facilities producing such mate rials and at facilities where hazardous materials are part of the production pr ocesses. Storage refers to the bulk handling of hazardous materials before and after they are transported to the general geographical area of use. Currently, hazardous materials are transported throughout Californi a via all modes of trans portation including rail, highway, water, air, and pipeline.

State law requires detailed planning to ensure that hazardous materials are properly handled, used, stored, and disposed of to prevent or mitigate injury to

health or the environment in the event that such materials are accidentally released. The Office of Emergency Services (OES) enforces these requirements. Federal laws, such as the Emergency Planning and CommunityRight-to-Know Act of 1986 (also known as Title III of the S uperfund Amendments and Reauthorization Act or SARA) impose similar requirements.

The U.S. Department of Tr ansportation (U.S. DOT) has regulatory responsibility for the safe transport of hazardous mate rials between states and to foreign countries. U.S. DOT regulat ions govern all means of transportation, except for those packages shipped by mail. Hazar dous materials sent by U.S. mail are covered by U.S. Postal Service (USP S) regulations. Common carriers are licensed by the California Highway Patrol (CHP), pursuant to the California Vehicle Code, §32000. This section requi res licensing of every motor (common) carrier who transports, for a fee, in ex cess of 500 pounds of hazardous materials at one time and every carrier, if not for hi re, who carries more than 1,000 pounds of hazardous material of the type requiring placards.

The CHP and Caltrans have primary respons ibility for enforcing federal and State regulations and responding to hazardous ma terials transportation emergencies.

The CHP enforces hazardous material s and hazardous waste labeling andMay 7, 2007 Appendix E 24 packaging regulations that prevent leakage and spills of material in transit and provide detailed information to cleanup cr ews in the event of an accident. Vehicle and equipment inspection, shipment preparation, contai ner identification, and shipping documentation are all part of the responsibility of the CHP. The CHP also conducts regular inspections of licensed transporters to assure regulatory compliance.

Pursuant to the Emergency Servic es Act, California has developed an Emergency Response Plan to coordinat e emergency services provided by federal, State, and local government agenc ies and private persons. Response to hazardous materials incidents is one part of this plan. The plan is administered by OES, which coordinates the responses of other agencies including U.S. EPA, CHP, Department of Fish and Game, the ap plicable regional water quality control board, and local fire depar tments (see California Government Code, §8550).

In addition, pursuant to the Hazardous Materials Release Response Plans and Inventory Law of 1985 (the Business Plan Law), local agencies are required to develop area plans for response to releas es of hazardous materials and wastes. These emergency response plans depend to a large extent on the business plans submitted by persons who handle haz ardous materials. An area plan must include pre-emergency planning of pr ocedures for emergency response,

notification and coor dination of affected governm ent agencies and responsible parties, training, and follow-up. Hazar dous materials incidents are reported to OES, which compiles and archives the information.

Public Health

The Toxic Air Contaminant Identification and Control Act (Health and Safety Code §§ 39650 et seq ., Food and Agriculture Code Sections 14021 et seq .) established California’s two-phased program to identify and control air toxics. In the first phase (risk assessment), ARB selects substances for review, considering criteria relating to “the risk of harm to public health, amount or potential amount of emissions, manner of, and exposure to, usage of the substance in California, persistenc e in the atmosphere, and ambient concentrations in the community” (Health and Safety Code § 39666(f)). One example of an identified TAC is particul ate matter from diesel-fueled engines.

In the risk management phase of the program, ARB reviews the emission

sources of an identified TAC to determine if any regulatory action is necessary to reduce the risk. The analysis includes a revi ew of controls already in place, the available technologies and associated costs for reducing emissions, and the

associated risk.

Also in the risk management phase, ARB, work ing closely with the air districts, is responsible for developing control measures for all identified TACs except those used as pesticides. Pesticides are ev aluated in a similar process by theMay 7, 2007 Appendix E 25 Department of Pesticide Regulation. Following ARB adoption of measures to control a specific toxic compound, the districts must adopt equal or more stringent regulations for the stationary sources in their jurisdiction. Regulations

to control airborne toxic emissions from mo bile sources are the responsibility of

ARB.

The Air Toxics Hot Spots Program (H ealth and Safety Code §§ 44300-44384) requires facilities to report their toxic ai r emissions, ascertain health risks, and to notify nearby residents of signifi cant risks. Facilities that pose a significant health risk to the community are required to reduce their risk through a risk management plan.

Worker Safety Requirements

The California Occupational Safety and Health Administra tion (Cal/OSHA) and the Federal Occupational Safety and He alth Administration (OSHA) are the agencies responsible for assuring worker safety in the handling and use of chemicals in the workplace. In Ca lifornia, Cal/OSHA assumes primary responsibility for developing and enforcing workplace safety regulations. Under the authority of the Occ upational Safety and Health Act of 1970, OSHA has adopted numerous regulations pertaining to worker safety (contained in 29 CFR). These regulations set standards for safe workplaces and work practices, including the reporting of accidents and occupational injuries. Some OSHA regulations contain standards relating to hazardous materials handling, including workplace conditions, employee protecti on requirements, firs t aid, and fire protection, as well as material handling and storage. Because California has a federally-approved OSHA program , it is required to adopt regulations that are at least as stringent as those found in 29 CFR.

Cal/OSHA regulations concerning the use of hazardous materials in the workplace (detailed in CCR, Title 8) include requirements for employee safety training, availability of safety equipment, accident and illness prevention programs, hazardous substance exposu re warnings, and emergency action and fire prevention plan preparation. Cal/OSHA enforces hazard communication program regulations contai ning training and information requirements, including procedures for identifying and labeling hazardous substances. The hazard communication program also requires that Material Safety Data Sheets (MSDSs) be available to employees and that em ployee information and training programs be documented. These regulations also require preparation of emergency action plans (escape and evacuation procedures, rescue and medical duties, alarm systems, and emergency evacuation training).

Both federal and State laws include specia l provisions for hazard communication to employees in research laboratories, including training in chemical work practices. The training must include inst ruction in methods for the safe handling of hazardous materials, an explanation of MSDSs, use of emergency responseMay 7, 2007 Appendix E 26 equipment and supplies, and an explanation of the bu ilding emergency response plan and procedures. Chemical safety info rmation must also be available at the workplace. More detailed training and monitoring is required for the use of carcinogens, ethylene oxide, lead, asbesto s, and certain other chemicals listed in 29 CFR. Emergency equipment and supplies, such as fire extinguishers, safety showers, and eye washes, must also be ke pt in accessible places. Compliance with these regulations reduces the risk of accidents and adverse worker health

effects.

The National Fire Code (NFC), St andard 45 (published by the National Fire Protection Association) contains standards for laboratories using chemicals that are not requirements but are generally em ployed by organizations in order to protect workers. These standards provi de basic protection of life and property in laboratory work areas through prevention a nd control of fires and explosions, and also serve to protect personnel from expos ure to non-fire health hazards. While NFC Standard 45 is regarded as a national ly recognized standard, the California Fire Code (24 CCR) contains State standards for the use and storage of hazardous materials and special standards for buildings where hazardous

materials are found. Some of these r egulations consist of amendments to NFC Standard 45. California Fire Code regulat ions require emergency pre-fire plans to include training programs in first aid, the use of fire equipm ent, and methods of

evacuation.

IX. Land Use/Planning

Cumulative Impact: The St ate Strategy is not expec ted to cause any adverse impacts on land use and planning.

X. Mineral Resources

Cumulative Impact: The St ate Strategy is not expec ted to cause any adverse impacts on mineral resources.

XI. Noise

Cumulative Impact: The cumulative effe ct of the State Strategy will not have a potentially significant impact on noise, although an increase of the number of trucks idling at inspection stops may result in increased noise.

Diesel-Fueled Engines — The recommended measures to reduce emissions from diesel-fueled engines could require the use of add-on control devices such as particulate filters, oxidation cata lysts and engine modifications. This could result in a potential increase in noise levels due to exhaust system changes to accommodate add-on controls. However, te sting of current add-on controls has shown no increase in noise, and ARB staff does not expect future adverse noise impacts.May 7, 2007 Appendix E 27 XII. Population and Housing

Cumulative Impact: The St ate Strategy is not expec ted to cause any adverse impacts on population and housing.

XIII. Public Services

Cumulative Impact: The St ate Strategy is not expec ted to cause any adverse impacts on public services.

XIV. Recreation

Cumulative Impact: The St ate Strategy is not expec ted to cause any adverse impacts on recreation. By reducing the number of days with unhealthy air quality, ARB expects that our parks and out door recreational facilities could see increased usage by children, the elderly , asthmatics, and others with sensitive airways or chronic breathing problems.

XV. Solid/Hazardous Waste

Cumulative Impact: The cumulative impact of all strategies in the State Strategy would be a small, but potentially signific ant, increase of both solid and hazardous wastes. To mitigate these impacts, ARB will work with the California Department of Toxic Substances Control (DTSC) and the California Integrated Waste Management Board (CIWMB) to reduce wa ste production in these and other

areas.

State and local agencies currently regul ate solid and hazardous waste. A discussion of these regulations will fo llow the proposed strategies below.

Vehicle Retirement Program

— High-mileage and older vehicles are likely candidates for scrappage rendering them i noperable to pollute. There are many

non-hazardous materials in a vehicle that could be discarded in landfills. Such

materials include iron and al uminum engine blocks, st eel and plastic from chasses and interiors, glass, chromi um-containing bumpers, and rubber hoses. Mitigation for the expansion of this pr ogram would involve reusing or recycling the above mentioned materials. According to the Bureau of Automotive Repair, on average 90 percent of a scrapped vehicl e is recycled with the remaining 10 percent considered fluff which is typically landfilled. A signific ant amount of scrap and recycled materials are shipped to foreign markets.

Diesel-Fueled Engines and Vehicles — The proposed measures to reduce emissions from diesel-fueled engines and v ehicles could require the use of new diesel engines or add-on control devices such as particulate filters and oxidation catalysts. Potential adverse impacts include increased scrapping of diesel engines and vehicles, and impacts due to handling and disposal of collectedMay 7, 2007 Appendix E 28 particulate matter. Also, diesel oxidat ion catalysts are considered hazardous at the end of life. The impact of accele rated vehicle scrapping can be largely mitigated by recycling and reclamation of hazardous materials.

Diesel Particulate Filters
— A number of measures in the State Strategy would require use of diesel particulate filter s. Diesel particula te filters will probably produce a small amount of wa ste ash for disposal. This waste is estimated at about 10 to 150 grams of ash per vehicl e per year and is projected to be

considered a hazardous material due to zinc content. While most larger maintenance facilities can be expected to handle, collect, and dispose of this material properly, it is less certain how smaller facilities will handle waste ash. The filters themselves will eventually also be retired. Some filters contain a precious metal catalyst that is valuable for recycling and reclaiming. Other spent filters may not be worth recycling and may be disposed of at a proper landfill. We do not expect that the spent filt ers themselves will be considered a

hazardous material.

Electrification of Equipment — Electrification equipment can provide significant reductions of air pollutant emissions. Ho wever, electrification strategies may result in the production and use of a si gnificant number of batteries. These batteries are normally recycled, and the recy cle rate for lead-acid batteries is currently more than 95 percent. However, the increase in the number of spent batteries to be processed would potent ially have significant impacts on the recycling industry and on the disposal syst em for non-recyclable materials. Leasing, deposit, or rebate programs for elec tric batteries could be required to increase recycling. A spent battery exc hange for battery replacement could also reduce waste impacts. With these mitigati on measures in place, battery disposal impacts should not be significant.

Solid Waste Regulations

Solid waste consists of residential wastes (garbage and rubbish produced by households), construction wastes, commercial and industrial wastes, home appliances and abandoned vehicles, and sludge residues (waste remaining at the end of the sewage treatment process). CCR Title 14, Division 7, provides the

State standards for the m anagement of facilities that handle and/or dispose of solid waste. CCR Title 14, Division 7, is administered by the CIWMB and the designated Local Enforcement Agency (LEA). The designated LEA for each county is the County Department of Environmental Health.

CCR Title 14, Division 7, establishes general standards to provide required levels of performance for facilities that handle and/ or dispose of solid waste. Other Title 14 requirements include operational plans, closure plans, and post-closure monitoring and maintenance plans. Title 14 covers various solid waste facilities including, but not limited to landfills, ma terial recovery fac ilities (MRF), transfer stations, and composting facilities.May 7, 2007 Appendix E 29 Hazardous Waste Regulations

Hazardous materials are substances with certain physical properties that could pose a substantial present or future hazard to human health or the environment when improperly handled, disposed, or otherwise managed. As defined in CCR Title 22, Division 4.5, Chapter 11, Article 3, hazardous materials are grouped into the following four categor ies based on their properties: toxic (causes human health effects), ignitable (has the ability to burn), corrosive (causes severe burns or damage to materi als) and reactive (causes explosions or generates toxic gases). A hazardous wa ste is any hazardous material that is discarded, abandoned, or otherwise is not recycled. If improperly handled,

hazardous materials and wastes can result in public health hazards if released to the soil or groundwater or th rough airborne releases in vapors, fumes, or dust.

Under the Resource Conservation and Recovery Act (RCRA), U.S. EPA regulates the generation, transportation, treatment, storage, and disposal of

hazardous waste. RCRA was amended in 1984 by the Hazardous and Solid Waste Act (HSWA), which affirmed and extended the concept of regulating hazardous wastes from generat ion through disposal. HSWA specifically prohibits the use of certain techniques for the disposal of some types of hazardous wastes. Under RCRA, individual stat es may implement their own hazardous waste programs in lieu of RCRA as long as the state program is at least as stringent as the federal RCRA requirem ents. U.S. EPA approved California’s program to implement federal r egulations as of August 1, 1992.

DTSC administers the Hazardous Wast e Control Law (HWCL). Under HWCL, DTSC has adopted extensive regulati ons governing the generation, transportation, and disposal of hazardous wastes. HWCL differs little from RCRA; both laws impose “cradle to grave” regulatory systems for handling hazardous wastes in a manner that pr otects human health and the environment. Regulations implementing HWCL are generally more stringent than regulations implementing RCRA. HWCL regulations list more than 780 hazardous chemicals, as well as nearly 30 more common materials that may be hazardous, and establish criteria for identifying, packaging, and labeling hazardous wastes. They prescribe management practices fo r hazardous wastes; establish permit requirements for hazardous waste tr eatment, storage, disposal, and transportation; and identify hazardous wastes that cannot be disposed of in

landfills.

Under both RCRA and HWCL, hazardous wa ste manifests must be retained by the generator for a minimum of three year s. Hazardous waste manifests list a description of the waste, its intended destination, and regulatory information about the waste. A copy of each mani fest must be filed with DTSC. The generator must match copies of hazardous waste manifests with certification notices from the treatment, disposal, or recycling facility. Hazardous waste asMay 7, 2007 Appendix E 30 defined in the Code of Federal Regul ations Title 40 (40 CFR) 261.20 and CCR Title 22, Article 9 (including list ed substances, 40 CFR 261.30) is disposed

of in Class I landfills. California has enac ted strict legislation for regulating Class I landfills (Health and Safety C ode, §§25209 - 25209.7). For example, the

treatment zone of a Class I landfill must not extend more than five feet below the

initial surface and the base of the zone mu st be a minimum of five feet above the highest anticipated elevation of underly ing groundwater (Health and Safety Code, §25209.1(h)). The Health and Safety Code also requires Class I landfills to be equipped with liners, a leachat e collection and removal system, and a groundwater monitoring system (Health an d Safety Code, §25209.2(a)). Such systems must meet the requirements of DTSC and the SWRCB (Health and Safety Code, §25209.5).

XVI. Transportation and Traffic

Cumulative Impact: Moderni zation of motor vehicle fl eets has the potential to generate increased travel. Because newer vehicles tend to be driven more frequently and make longer trips, this c ould increase the number of vehicles on the roads. Although modernization and turnover of fleets is intended to decrease the emissions from these vehicles, more vehicles on the roads could result in increased congestion.

XVII. Water Resources

Cumulative Impact: The St ate Strategy would signific antly reduce a number of air pollutants and the reductions in depositio n will improve overall water quality in California. Also, accelera ted retirement of older equi pment with potentially leaky gasoline or diesel engines will reduce fluid (oil and grease) drips, resulting in cleaner storm water runoff. Several potent ially significant adverse water quality impacts are identified, including im pacts from reformulated gasoline and reformulated low-VOC consumer products.

Although rain can effectively scrub the air clean, air pollutants absorbed by rainwater can have an adverse impact w hen deposited into surface waters. NOx

and SOx emissions can form acids that ca n lower the pH of sensitive mountain lakes and streams and adversely affect the flora and fauna. NOx emissions can oxidize to nitrate, a powerful fertilizer, and can spur algae growth contributing to lake water turbidity and algae blooms. Organic molecules can be deposited in surface waters and affect the aquatic pl ants and animals. Toxic air contaminants (TACs) can dissolve in rain and eventually stress or kill organisms.

This environmental analysis of water resources is divided into two major categories—water quality and water demand. However, no significant negative impacts on water demand were identified. Several State and federal agencies regulate water resources and water qualit y. A discussion of these agencies’ regulations will follow the Stat e Strategy potential impacts.May 7, 2007 Appendix E 31 Reformulated Gasoline — Ethanol in Gasoline Since the phase out of MTBE from Calif ornia gasoline formulations and federal denial of a request for a waiver from t he oxygenate requirement, California has reformulated its gasoline with ethanol. As modifications to the rule are developed, there may be an increase of the amount of et hanol used as an oxygenate. There is potent ial for biological effects fr om this formulation in the event there is discharge to groundwater or surface waters. Ethanol may have an impact on the biodegradation of hydrocarbons which can worsen the effects of a gasoline spill. Ethanol may inhibit biol ogical degradation of Benzene, Toluene, EthylBenzene and Xylene (BTEX) due to bacterial preference for ethanol resulting in longer groundw ater plumes of BTEX.

Diesel-Fueled Engines — The State Strategy to reduce emissions from onroad, off-road, and stationary diesel-fuel ed engines could require or encourage the use of alternatively f ueled engines and alternative fuel formulations. Because

some alternative diesel fuel formulat ions and additives could more readily dissolve in water, these control measures have the potential to adversely impact local ground and surface waters.

The use of these alternative fuels is not ex pected to result in significantly greater adverse water quality impacts than the use of regular diesel fuels. A number of rules and regulations are currently in plac e to minimize the potential impacts from underground leaking storage tanks and spills from fueling activities. These include requirements for the construction of the storage tan ks, requirements for double containment, and installation of leak detection systems. These regulations minimize the potential for additi onal leaks from the use of diesel fuels

or alternative fuels.

Consumer Products — Two toxic air contaminants (TAC) used in some consumer products, methylene chloride (Me Cl) and perchloroethylene (Perc), are specifically exempted from the VOC definition in reco gnition of their very low ozone-forming capabilities. Some manufactu rers could use MeCl or Perc in their

formulations to reduce the VOC content to meet future limits, creating potential adverse environmental impacts for primar ily air, and possibly, though much less likely, soil and water.

ARB staff has recognized the potential fo r increased use of TACs in consumer products and has taken steps to mitigate and limit the use of these compounds in

recent Board actions. These actions in clude: the toxics control measure for automotive maintenance and repair activiti es; aerosol adhesives limits in the consumer products regulation; the prohibiti on of para-dichlorobenzene in solid air fresheners and toilet/urinal care products; an d reactivity limits in the aerosol coating regulations. ARB periodically su rveys all categories for their chemical composition including TA Cs and also tracks the use of MeCl and Perc in regulated consumer products thro ugh yearly manufacturer reporting requirements. Further, ARB staff has pr oposed VOC limits in the past that wereMay 7, 2007 Appendix E 32 achievable without the incr eased use of TACs. Furthermore, Proposition 65 labeling requirements disc ourage manufacturers from reformulating consumer products with TACs.

ARB staff actively seeks to prevent increased use of TACs when setting new VOC limits. In the future, if new produc ts contain Perc and MeCl, ARB staff will monitor their use and limit or prohibit t heir use in additional consumer products, when applicable. Mitigation measures will be implemented if a significant presence of consumer product-related Pe rc is anticipated in wastewater.

Vehicle Retirement Program

— High-mileage and older vehicles are likely candidates for scrappage. Their deteriora tion leads to increased emissions. Once scrapped, they can no longer po llute. Scrapped vehicles commonly contain residual fuels, such as gasoline, lubricating oils and other fluids that may potentially harm water quality if not proper ly handled. There are regulations and rules to properly manage these programs, however, there is a potential for adverse environmental impac ts if these pollutants are leaked to surface and groundwater.

State and Regional Water Boards

California has an extensive regulatory pr ogram to control water pollution. The most important statute gov erning water quality is the Porter-Cologne Act, which gives the State Water Resources Contro l Board (SWRCB) and the nine regional water quality control boards (RWQCB) broad powers to protect surface and groundwater supplies in California, regul ate waste disposal, and require cleanup of hazardous conditions (California Wate r Code §§3000-13999.16). In particular, the SWRCB establishes water-related pol icies and approves water quality control plans, which are implemented and enforced by the RWQCBs. The nine regional boards include: North Coast, San Franci sco Bay, Central Coast, Los Angeles, Central Valley, Lahontan, Colorado River Basin, Santa Ana, and San Diego.

It is the responsibility of each regional board to pr epare water quality control plans to protect surface and groundwater s upplies within its region. These plans must: identify important regional water resources and their beneficial uses, such as domestic, navigational, agricultural, industrial, and recreational; establish water quality objectives, limits, or levels of water constituents or characteristics established for beneficial uses and to prevent nuisances; and present an implementation program necessary to ac hieve those water quality objectives. These plans also contain technical information for determining waste water discharge requirements and taking enforcement actions. The plans are typically reviewed and updated every three y ears (California Water Code §13241).

California dischargers of waste that “could affect the quality of the waters of the State” are required to f ile a report of waste disc harge with the appropriate regional water board (California Water C ode §13260). The report is essentially aMay 7, 2007 Appendix E 33 permit application and must contain informati on required by the regional board. After receipt of a discharge report, the r egional board will issue “waste discharge requirements” analogous to a permit with conditions prescribing the allowable nature of the proposed discharge (Ca lifornia Water Code §§3263, 13377, and 13378).

National Pollutant Discharge El imination System Requirements

Most discharges into California’s waters are regulated by the National Pollutant Discharge Elimination System (NPDES), a regulatory program under the federal Clean Water Act. The NPDES is supervised by U.S. EPA, but administered by the SWRCB. NPDES requirements apply to discharges of pollutants into navigable waters from a point source, di scharges of dredged or fill material into navigable waters, and the disposal of sewage sludge that could result in pollutants entering navigable waters. Ca lifornia has received U.S. EPA approval of its NPDES program. Pursuant to California’s NPDES program, any waste discharger subject to t he NPDES program must obt ain an NPDES permit from the appropriate RWQCB. The permits typi cally include criteria and water quality objectives for a wide range of constit uents. The NPDES program is selfmonitoring, requiring periodic effluent sa mpling. Permit compliance is assessed monthly by the local RWQCB. Any NPDE S violations are then categorized and reported to U.S. EPA on a quarterly basis.

U.S. EPA has also published regulations that require certain industries, cities and counties to obtain NPDES permits for st ormwater discharges [55 CFR (1990)]. The regulations set permit application r equirements for classes of stormwater discharges specifically ident ified in the federal Clean Wa ter Act. The regulated stormwater discharges include those associ ated with industrial activity and from municipal storm sewer systems servi ng a population of 100,000 or more.

Discharges to Publicly-Owned Treatment Works (POTWs)

Water discharges to a public sewage system (referred to generically as a POTW), rather than direct ly to the environment, are not subject to the NPDES discharge requirements. Instead, such discharges are subject to federal pretreatment requirement s under §§307(b) and (c) of the Clean Water Act [33 USC §1317(b)-(c)]. Al though these pretreatment standards are enforced directly by U.S. EPA, they are implement ed by local sanitation districts (Monahan

et al. , 1993). The discharger, however, has the responsibility to ensure that the waste stream complies with the pretreatment requireme nts of the local system. Any facility using air pollution control equipment affecting water quality must receive a permit to operate from the loca l sanitation district. In cases where facilities modify their equipment or install air pollution controls that generate or alter existing wastewater streams, owner/operators must notify the local sanitation district and request that their existing permit be reviewed and modified.May 7, 2007 Appendix E 34 To ensure compliance with wastewater pret reatment regulations, local sanitation districts sample and analyze the wa stewater streams from facilities approximately two to four times per year. Persons who violate California’s water quality laws are subject to a wide array of enforcement provisions. In 1990, U.S. EPA revised and extended existing regulations to further regulate hazardous waste dischargers and require effl uent testing by POTWs. To comply with revised permit limits, POTWs may al ter their operations or impose more stringent local limits on indus trial user discharges of hazardous wastes (Monahan

et al ., 1993). POTWs in California are operated by sanitation districts that adopt ordinances establishing permi t systems and fee structures.

Department of Pesticide Regul ation’s 2008 Pesticide Element

The pesticide element requires the Departm ent of Pesticide Regulation (DPR) to implement regulations that re strict the amount of VOCs that may be emitted from field fumigation. The 2008 element updates the current pestici de element of the ozone SIP, which provides for percent age reductions in emissions from 1990

levels.

An analysis of potentially significant env ironmental effects will occur before final implementation of the specific field fumigant regulations. The fumigant regulations have been developed enough to assess the potential environmental impacts at this point.

Cumulative Impact of 2008 Pesticide Element : Adoption of this element into the SIP would not have significant or potent ially significant adverse effects on the

environment.

Potential Environmental Impact s of 2008 Fumigant Regulations

The fumigant regulations to be implement ed in 2008 will establish limits on the amount of VOCs that may be emitted from field fumigation in certain areas and will prescribe allowable applic ation methods statewide. Pesticide applicators are expected to take one or more of the following actions to comply with the regulations: Use lower emission applicat ion methods, reduce application rates, reduce the acres fumigated, and shift fumigant applications outside the peak ozone season. DPR expects most of t he required emission reductions to come through use of lower emission applicati on methods, generally tarping, postfumigation water treatments, and drip c hemigation. The r egulations will give applicators a choice of application met hods, but in general the impacts will be negligible regardless of wh ich options are selected.

DPR's review of the proposed action s howed that no significant adverse environmental impact to California's envir onment can reasonably be expected to occur from implementing it s commitment to promulgat e fumigation regulations.May 7, 2007 Appendix E 35 In reaching this conclusion, DPR c onsidered the possible impacts discussed

below.

Air Quality

Shifting fumigations outside the peak ozone season could cause current particulate emissions from tractors and other application equipment to shift from summer to late fall or early spring . However, increased fumigations and associated particulate emissions during the winter peak particulate season are unlikely due to wet fields and other constraints.

Since the 2008 fumigant r egulation would establish application limits during May through October only, there is a potential for an increas ed use of fumigants in the months preceding or follo wing the peak ozone season. However, current DPR regulations and U.S. EPA label restricti ons are designed to prevent acute or chronic toxic exposure and are sufficient to avoid any adverse effects of toxic emissions from any increased use of fumigants.

In addition, the restriction of allow able application methods in the proposed regulations will reduce air emissions of the fumigants. Emissions of fumigants included in the proposed regul ation have little or no cont ribution to particulate matter pollution, acid rain, climate change, or other ai r quality impacts.

Agricultural Resources

Reducing the acreage fumigat ed would cause the previously fumigated fields to be converted to crops that do not use fu migants or to non-agricultural uses. The most likely conversions in specific areas are unknown at this time. DPR expects that growers in all areas can, and will, meet the emi ssion limits primarily through changing application methods, and thus the regulations will not cause a significant reduction in the number of acres fumigated or conversion of agricultural land to other uses.

Resource/Energy Use

Post-fumigation water treat ments and drip chemigation (pesticide application via an irrigation system rather than by tractor applicati on) will require greater quantities of water, with associated energy use and other effect s. Less diesel

fuel and other desirable effects associat ed with decreased tractor use will offset any potential impacts. However, the relati ve increase from current water use is expected to be negligible.

Solid Waste

The disposal of solid waste may increase slightly due to use of plastic tarpaulins under the proposed regulations, but the increase is not expected to be significantMay 7, 2007 Appendix E 36 since a great majority of the fumigations already use tarpaulins when it is a feasible mitigation measure.

Water Quality

DPR’s evaluation of the post-fumigation water treatments and drip chemigation applications show virtually no potential for ground water contamination by the fumigants with the estimated irrigation increases.

Other

Fumigation is primarily used to contro l diseases and nematodes. If fumigant application rates are reduced as a result of the regulations, use of non-fumigant pesticides, such as fungicides and nemat icides could be increased. Increasing

the use of such non-fumi gant pesticides may result in potential adverse environmental impacts to soil, air or water.

Environmental Analysis for the Proposed Revision to the Pesticide

Commitment in the 1994 Ozone SIP

Aside from the Ventura ar ea, the 2008 pesticide element requires the same or

more VOC reductions than the current pesticide element (1994 Plan). The 2008 pesticide element does, however, allow less VOC reductions for pesticide use in the Ventura area only. Either plan would provide for significant reductions from actual, current levels. For Ventura Count y to meet the targets of the 1994 Plan, 2.2 tons per day reductions are requi red. The 2008 pesticide element would require a 1.2 ton per day reduction that would result from the 2008 fumigation regulations. The additional ton of VOC reductions needed to satisfy the 1994

SIP commitment will instead come from other sources of VOCs in the Ventura

area. A more detailed discussion of this allowance and emission reduction offsets is included in the Appendix H.

Potential environmental impacts resulting from the proposed revision to the 1994 Plan may come from the use of methyl bromide and methyl isothiocyanategenerating fumigants. These fumigants co mprise approximately 50 percent of the pesticide VOC inventory in Ventur a. These two fumigants have very low reactivity, indicating that they do not appreciably contribute to ozone formation. Methyl bromide is an ozone depleti ng substance, and its production and importation are regulated under the Clean Air Act. Ozone depletion is not a localized effect, and the amount of methyl bromide emitted due to this Plan is negligible. It is estimated that 0.5 t ons per day more methyl bromide will be emitted from field fumigation under the 2008 pesticide element target than would

be allowed under the 1994 Plan. This is approximately 0.0002 percent of the worldwide methyl bromide emissions. No other adverse effects should occur because the fumigants included in the proposed regulation have little or noMay 7, 2007 Appendix E 37 contribution to particulate matter pollution, acid rain, climate change, or other air quality impacts.

DPR regulations and U.S. EPA label restrict ions currently in place are designed to prevent acute or chronic toxic exposure. They are sufficient to avoid adverse effects of toxic emissions from any additi onal use of these fumigants that would result if the VOC reduction targets in the pesticide element of the SIP were one ton per day higher in Ventura in 2008.

Cumulative Impact of Proposed Revision to the 1994 Plan: The change to the 2008 pesticide element targets will not have a significant adverse environmental impact on air quality.

Cumulative Impacts of State Measu res and Local District Measures

The cumulative impacts of the State Strategy within each impact area have been discussed in the previous sections. This analysis does not set forth the environmental impacts of measures contai ned in district plans, as districts are required to perform their own environmental analysis of their stationary source

control measures. The 8-hour Ozone and PM2.5 SIP, however , will incorporate

both state and local m easures. Local measures fr om the non-attainment areas may also have adverse environmental impacts . Interested parties that want to review and assess impacts associated wit h each district should do so at the district level. ARB, as the state agency responsible for preparing the SIP, coordinating district efforts to co mply with federal SIP requirements and forwarding the SIP components to U.S. EPA, will collect and compile the each district’s plan, along with their envir onmental documentation, and send the entire SIP package to U.S. EPA.

At this time, the air dist ricts with the most serious air quality problems in the State, South Coast Air Basin and the San Joaquin Valley, both have performed environmental analyses for their plans. All other non-attainm ent districts are expected to perform environmental analyses prior to adoption by their respective

district boards.

The cumulative impacts discussion contai ned in the South Coast Air Quality Management District’s Draft Environmental Impact Report (EIR) for the 2007 Air Quality Management Plan, is hereby inco rporated by reference. The San Joaquin Valley Unified Air Pollution C ontrol District Initial Study/Proposed Negative Declaration is also her eby incorporated by reference.May 7, 2007 Appendix E 38 Project Alternatives

As discussed at the beginning of this appendix, ARB meets the criteria for a Certified State Regulatory Pr ogram. This certification requires ARB to present a range of reasonable alternatives for any project under consideration. CEQA requires a certified agency to include one of the following in the document: 1) Alternatives to the activity and miti gation measures to avoid or reduce any significant or potentially significant effe cts that the project might have on the environment; or 2) A statem ent that the agency’s review of the project showed that the project would not have any significa nt or potentially significant effects on the environment, and therefore no alter natives or mitigation measures are proposed to avoid or reduce any signific ant effects on the environment. The

statement shall be su pported by a checklist or other documentation to show the possible effects that the agency examined in reaching this conclusion. (CEQA Guidelines Section 15252).

The alternatives presented in this appendix were evaluated for their comparative merits to the proposed project. Under CEQA, the alternatives are required to feasibly obtain the objectives of the propos ed project. For this reason, it is important to note the State of California is under legal obligation to prepare a State Implementation Plan wh ich demonstrates it will r each attainment for the

8-hour ozone and PM2.5 standards.

Review of the cumulative impacts from all proposed new measur es or strategies shows there may be potentially significant adverse impacts if all measures are adopted. Therefore, alternatives to the State Strategy are considered below.

Alternative 1 — No Project

CEQA documents typically assume that t he adoption of a ‘no project’ alternative

would result in no further action on t he part of the project proponent or lead agency. For example, in the case of a proposed housing development project, adopting the ‘no project’ alternative termi nates further consideration of that housing development or any housing develop ment alternative identified in the
associated CEQA document. In that ca se, the existing setting would remain unchanged.

One interpretation of the ‘no project’ alte rnative is that if this alternative was selected, all the measures in the State Strategy are rejected. Since the State Strategy contains all currently known feas ible State strategies or measures that ARB could potentially take to reduce oz one-forming emissions, this would mean that no additional measures on existing sources or measures on uncontrolled sources would be developed. The result would be the eventual deterioration of California air quality as population increases and would very likely prevent the State from being able to meet its requirement to meet the 8-hour ozone and PM2.5 standards. In addition, California wo uld fail to meet federal Clean Air ActMay 7, 2007 Appendix E 39 mandates and would be subject to federal sanctions. Water quality would suffer

as acidic rain increases and toxic air contaminants are deposited on the ground. Public exposure to toxic ma terials would increase. Higher levels of air pollutants would deteriorate aesthetics by increasi ng haze and would damag e crops. Only

modest benefits would be achieved from a no project alternatives, such as any

small increase in solid or hazar dous waste would not be generated.

Alternative 2 — Adopt Fewer Measures

As mentioned previously, the State Strat egy contains all measures to reduce

ozone that ARB staff has determined are feas ible to achieve. Instead of adopting all of these measures, ARB could adopt only some of them, although there would

be numerous alternative subset s of the measures identifi ed in the State Strategy to consider. However, adopting fewer meas ures would not result in the expected

emissions reductions needed to meet t he 8-hour ozone and PM 2.5 standards. This would then place an increased res ponsibility on local districts and the federal government to achieve suffici ent emissions reductions to meet the

standard.

Alternative 3 — Adopt Measures with Different Emission Standards

For each individual measure, many alternat ives exist for various levels of control and variable emission standards for the regul ated sources. It is not possible to examine these many alternatives in detail without engaging in speculation, because the measures ultimately adopt ed by ARB will depend on the information that is learned in the future during t he regulatory development process. In general, however, ARB staff believes that it will be necessary to adopt all State Strategy measures and emission standards that are determined to be feasible,

rather than a subset of feasible measur es and standards. To attain the federal

ozone standard in the South Coast and San Joaquin Valley, sign ificant additional emission reductions will be needed beyond the defined measures specifically identified in the Strategy. Therefore, failing to adopt all feasible measures and

emission standards would result in fa ilure to meet federal Clean Air Act mandates and would subject the St ate to federal sanctions.

Impacts of Individual Proposed Measures

The measures in the State Strategy wil l help make progress toward our goal of healthy air for all Californians. Each of the defined St ate measures was evaluated to identify adverse environmental impacts.

Introduction

ARB staff has estimated the costs and ec onomic impacts that could result in 2014 from the proposed State Strategy to reduce emissions of oxides of nitrogen (NOx), reactive organic gas es (ROG), fine particulate matter (PM2.5) and oxides of sulfur (SOx) in the South Coast and San Joaquin Valley St ate Implementation Plans (SIP). The emission reductions are needed to meet the attainment

deadlines for the federal 8-hour ozone and PM2.5 standards. This analysis includes the costs and economic impacts of all proposed control measures under State jurisdiction, including passenger vehicles and trucks, goods movement, construction and mining equipment, engi ne exhaust and evaporation, and consumer products. It is im portant to note that the cost s reflected in this section represent costs incurred in 2014 only alt hough some measures will begin to be implemented prior to 2014 and continue after 2014.

The proposed State Strategy measures, when adopted as rules or regulations, are likely to cause technological changes that could increase the production costs for regulated industries. In creased costs could have an initial contractionary effect on those industries, which in turn could affect other related industries either negatively or positively. For example, indus tries that provide supplies and services to affected indus tries could experience a reduction in demand for their products and services whil e suppliers of environmental products and services could experience an increase in their sales. The net effect on the California economy of these activities hinges on the extent to which products and services are obtained locally. Usi ng an updated version of EnvironmentalDynamic Random Analysis model (E-DRAM) 1 , staff estimated the net effects in

2014 of these activities on the affected industries and the overall economy. The

California industries affected most are those engaged in the production, distribution, sales, and use of cars and trucks, goods movement, off-road equipment and engines, and consumer products.

The proposed State Strategy would bring about significant societal benefits, including less illness and medi cal expenses and fewer lost work and school days, to Californians. In its report to C ongress in 1999, U.S. EPA found that the

dollars in societal benefits.

Annual direct costs of all proposed State Strategy measures are estimated to be $4.6 billion in 2014. Increased costs that would result from the proposed State Strategy would reduce California’s economic output in 2014 from $2.948 trillion to $2.938 trillion (roughly $10 billion or 0.30 percent), personal income by $5 billion (0.30 percent), and California employm ent by approximately 37,000 jobs (0.20 percent). These changes reflect a sli ght slow-down in the growth of the California economy from what it would be otherwise. From 2007 through 2014, California output is expected to grow by $74 billion, personal income by $45 billion, and employment by 198,900 per year. The impact of the proposed State Strategy would be a slight reduction in the annual growth rate of: economic output (from 2.85 percent to 2.80 percent); personal income (from 2.90 percent to 2.88 percent); and employment (fro m 1.20 percent to 1.17 percent).

Cost of Control Measures

Most control measures i dentified in the proposed Stat e Strategy rely on the application of current technologies to ac hieve additional emission reductions. Some control measures, however, rely on the development of new technologies. The implementation of these control measures may fundamentally change the ways many products are manufactured, distributed, and used. Whether these changes require the reformulation of a cons umer product or gaso line, retrofit of diesel trucks and buses, more st ringent standards on in-board and outboard marine engines or modernization of port trucks, we assumed that they impose costs on businesses. This analysis provi des estimates of those direct costs.

ARB staff estimated the cost of each c ontrol measure using the most reliable

information available. For some contro l measures, staff developed control costs directly based on the application of curr ent technologies. For most control measures, however, staff estimated control costs indirectly by multiplying either the cost-effectiveness estimate by the emission reduction associated with the proposed State Strategy measur e, or an estimate of the unit cost increase by the number of products that ar e projected to be used.

The control costs in this report represent very rough estimates of the costs of the proposed State Strategy and may change when more specific regulatory language is developed. There is an ext ensive public process as part of the development of each proposed State Stra tegy measure into a regulation or program. ARB staff gather s detailed industry-specific information and assesses the potential costs to businesses, gover nment, and consumers. The measures will be discussed at public workshops , and proposed regulations will go through the public hearing process as required by law. When specific regulatory language is developed, it will be possible to analyze potential costs andMay 7, 2007 Appendix E 54 economic impacts in more detail. This information will be presented with each regulatory proposal for Board consideration.

Cost-effectiveness Estimates

Cost-effectiveness is an estimate of the unit cost of reducing a pollutant which varies by pollutant and control strat egy. The ARB cost-effectiveness estimation of its past control measures for ROG r eductions from consumer products range from under $0.50 per pound ( $1,000 per ton) to about $6 per pound ($12,000 per ton). For NOx+ROG reductions from mob ile sources, the range varies from less than $0.50 per pound ($1,000 per ton) to abo ut $3 per pound ($6,000 per ton). The figures below show cost-effectivene ss estimates for California consumer products and mobile source control and f uel measures approved by the ARB in the late 1980s, 1990s, and early 2000s.

In the early 2000s, ARB adopted a number ofPM control measures. The costeffectiveness estimates for those meas ures ranged from $7 per pound ($14,000 per ton) to $28 per pound ($56,000 per ton).

For the purpose of this analysis, ARB sta ff made a very conservative assumption

that future emission reductions will be mo re expensive to obtain than the past

reductions. This is because firms are r equired to meet more stringent air quality

standards or to control emission sources previously unregulated because of the high cost of control. In the past, however, businesses have always found innovative ways to meet standards at costs much lower than estimated by staff.

We have no reason to believe that this tr end will not continue in the future. For example, in 1988 the South Coast Air District estimated the cost of NOx reduction from a natural gas-fired pow er plant to be about $25,000 per ton compared to the industry estimate of $45, 000 per ton. By 1995, when the rule requirements became effective, the actual cost of NOx control from power plants was about $12,000 per ton. Similarly, ARB staff estimated the cost to control evaporative emissions from vehicles to be about $170 per vehicle in 1990 while Cost-Effectiveness of Major Regulations

The cost-effectiveness estimates used fo r the proposed State Strategy ranged from a low of approximately $3,000 to a high of $32,000 per ton of ROG emissions reduced, from $3,000 to $43,000 per ton of NOx em issions reduced, and from $5,000 to $55,000 per ton of PM emissions reduced. The costeffectiveness estimates for SOx range from $8,000 to $43, 000 per ton and are based on the use of clean fuels in ships and cold ironing of ship engines. These two measures are expected to reduce SO x emissions by 75 tons. The tables

below illustrate how the cost of reducing a ton of eit her ROG or NOx would rise as more emission reductions are required. All cost-effectiveness numbers are in

Annual Costs

Annual direct costs of all proposed State Strat egy measures in 2014 are estimated to be approximately $4.6 billion. This represents about 0.2 percent of the California Gross State Product (GSP) in 2014. GSP measures the value of all goods and services produced in California in a given year.

The table below provides estimates of total annual costs of the proposed State Strategy by source categories for the y ear 2014. Measures to reduce emissions from heavy-duty trucks alone account for 57 percent of annual State Strategy

costs. Measures to reduce emissi ons from passenger cars and heavy-duty

trucks combined account for 66 percent of the costs.

Measures to reduce emissions from goods movement at Califor nia ports account for 26 percent of annual proposed State Strategy costs, of which about 81 percent stems from the use of cleaner engines and fuel for ships and the application of cold ironing to auxiliary ship engines. The remaining annual State Strategy cost is associated with measures that intend to reduce emissions from construction equipment (4 percent),May 7, 2007 Appendix E 59 off-road engine exhaust and evaporation (3 percent), and consumer products (1 percent). All costs are in constant 2006 dollars.

Annual costs of the proposed State Strategy can also be classified by the type of pollutants. The table be low provides a list of a ffected pollutants and their

associated costs. As shown in the follo wing table, NOx cont rol accounts for 75 percent of total annual costs, ROG control for 15 percent, SOx control for 5 percent and PM2.5 for 5 percent. Of $4.6 billion total annual statewide costs, the

cost for South Coast businesses and cons umers will be $1.3 billion or 29 percent of statewide costs, and for San Joaqui n Valley businesses and consumers it will be $757 million or 16 percent of the statewide costs.May 7, 2007 Appendix E 60 Estimated Annual Costs of the Propo sed State Strategy by Pollutants (Millions of 2006 Dollars)

In order to estimate the total impac t of the proposed Stat e Strategy on the California economy, we also classified these costs according to the latest

E-DRAM industrial sector classificati ons. The new model has 108 industrial sectors, of which six industrial sectors and one hous ehold sector would be affected directly by the proposed State Strategy. The next table provides estimates of total annual costs by a ffected industries and government. About 1 percent of the total annual cost would be borne by government and about 83 percent by transportation industry. T he balance will be borne by the vehicle service industry (6 percent), constructi on industry (4 percent), boat and shipping repair industry (3 percent), petroleum refinery industry (2 percent), and chemical and drug industry (1 percent).

Economic Impacts

Control costs provide a means to estima te the direct expenditures that will be incurred by California businesses, gover nments, and individuals to meet the requirements of the proposed State Strategy . These costs would in turn bring about additional (indirect) changes in the California economy that may increase

the overall costs. Increased control cost s, for example, may result in higher product prices. California firms may respond by cutting back production andMay 7, 2007 Appendix E 61 decreasing employment. On the other hand, the planned control measures may

also increase demand for environmental products and services, thus inducing firms supplying those products and serv ices to expand their production and increase their hiring of workers.

This change in costs will in turn a ffect other industries both negatively and positively. The net effect on the California economy of these activities hinges on the extent to which products and se rvices are obtained locally. Using a macroeconomic model, staff estimated the net effects of these activities on affected industries and the overall economy. The California industries affected most are those engaged in the production, distribution, sales, and use of passenger vehicles and trucks, goods mo vement, construction and agricultural equipment, engine exhaust and evaporatio n, and consumer products.

The economic model, however, does not account for the enormous benefits to

California businesses and citize ns that air quality regulat ions will bring. Improved air quality reduces illness and infant mo rtality and increases natural resources and work force productivity. Contro l programs also induce significant advancement of clean technologies. As st ated earlier, ARB staff estimates that

the benefits to California fr om currently adopted air pollution control measures exceed the costs by about three to one. That is, each dollar spent on clean air generates, on average, three dollars in so cietal benefits that improve the quality

of life.

Environmental-Dynamic Revenue Analysis Model (E-DRAM)

The overall impact of all direct and indi rect economic effects associated with the planned control measures ar e estimated using a comput able general equilibrium (CGE) model of the California econom y. A CGE model simulates various economic relationships in a market econom y where prices and production adjust in response to changes in behavior resulting from regulatory changes. More specifically, it describes the rela tionships among producers, consumers, government, and the rest of t he world. The CGE model used for this analysis is the latest updated version of the En vironmental Dynamic Revenue Analysis Model (E-DRAM). E-DRAM was firs t developed as DRAM for the California Department of Finance 4 . The model can be used to measure the total impact of a change caused by a regulation in one in dustry on all other industries within California. The economic impact results are measured in terms of changes in the State output, personal income, and employment.

The new model is based on a revised database called a social accounting matrix (SAM). The revisions to SAM include a ca libration of the base year in the model to calendar year 2003 from fiscal year 1998-1999, an updating of energy data, and a more detailed sectoring of the California economy. The new E-DRAM

4 For a complete description of DRAM, see Berc k, Peter, E. Golan and B. Smith, “Dynamic Revenue Analysis for California, Califor nia Department of Finance, Summer 1996.May 7, 2007 Appendix E 62 divides the California economy into 174 distinct sectors, consisting of 108 industrial sectors, two fact or sectors (labor and capital), eight household sectors (classified by income level), nine co mposite goods sectors, one investment sector, and 45 government sectors (sev en federal, 27 State, and 11 local), and one sector that represents the rest of the world.

Data for the industrial sectors originated with the Bureau of Economic Analysis of the U.S. Department of Commerce, based on the Census of Business – a detailed survey of companies conducted in the U.S. every five years. The conversion of national data to updated Calif ornia data is accomplished by Impact Analysis for Planning (IMPLAN), a program that primarily utilizes state-level employment data to scale nat ional-level industrial data down to the size of a

state.

In much the same way as firms, households are al so aggregated. California households were divided into categories based upon their taxable income. There are seven such categories in the model , each one corresponding to a California personal income tax marginal tax rate (0, 1, 2, 4, 6, 8, and 9.3 percent). Thus, the income for the “one-percent” househo ld is calculated by adding up the income from all households in the one-percent bracket.

Similarly, the expenditur e of the one-percent household on agricultural goods is calculated by adding up all expenditu re on agricultural goods for these

households. The total ex penditure on agricultural goods is found by adding the expenditure of all households together.

Overall Economic Impact

Increased costs of the propos ed State Strategy will affe ct the California economy through many complex interactions. E-DRAM was developed to simulate many of these complex interactions. Using t he model, ARB staff, in consultation with UC Berkeley researchers, conducted an a ssessment of the economic impacts of the proposed State Strategy on the California economy.

The results shown below are based on pr eliminary emission reduction estimates and may change slightly. ARB staff will perform a confirmatory analysis with EDRAM prior to the heari ng for Board approval.

The following table summarizes the impact of the proposed State Strategy on the California economy in the year 2014, bas ed on the E-DRAM results. We project the costs of the proposed St ate Strategy will reduce Ca lifornia economic output by roughly $9 billion (0.3 percent) and Cali fornia employment by approximately 37,000 jobs (0.2 percent) in 2014. Pe rsonal income would also decline by roughly $5 billion (0.3 percent) in 2014.May 7, 2007 Appendix E 63 Impact on the California Economy of Pr oposed State Strategy in the Year

Conclusion

Total annual direct costs associated with the proposed State Strategy are estimated to be approximately $4.6 billion in 2014, 29 percent of which will be on South Coast residents and 16 percent on San Joaquin residents. Accounting for indirect costs, the propos ed State Strategy is expe cted to reduce California economic output by about $9 billion, personal income by about $5 billion, and employment by about 37,000 in 2014. In th e context of the St ate’s economy, the economic impact of the propos ed State Strategy is small and is not expected to impose a noticeable impact. It should be noted here that the proposed State Strategy would bring about significant so cietal benefits to Californians. These benefits, which are difficult to expre ss solely in economic terms, are not quantified in this analysis. Prior analyse s have estimated that the benefits of California’s air quality regulations exceed the costs by a ratio of about three to

one.

### 1. Introduction

Purpose

This Emission Inventory Appendix describes the emission in ventory and the role it plays in the State Implementation Plan (SIP ) development process. An emission inventory is an estimate of the amount and type of pollutants emitted into the atmosphere over a defined period of time. Emission inventories se rve three principal roles in the developm ent of the SIP:

• They provide the emissions data used for developing control strategies;

• They are a primary input to photochem ical modeling used in attainment demonstrations; and

• They are used to track progress in m eeting the emission reduction commitments.

This document will discuss the requirements for SIP development as it pertains to emission inventories, descri be the elements (or sectors) that make up an emission inventory, provide an overview of the methodologies used to derive emission estimates, summarize the recent improvements to t he emission inventory, and explain how the emission inventory is document ed through Quality Assuranc e (QA) and Quality Control (QC).

Statutory Requirements

The federal Clean Air Act (CAA) contains the statut ory requirements for attaining clean air (air quality standards). The U.S. En vironmental Protection Agency (U.S. EPA) regulations list requirements pertaining to em issions information that must be included as part of the SIP submittal package. The regulations require t hat the SIP emission inventory contain the pollutants for whic h an area is nonattainment. For an 8-hour ozone SIP, the emission inventory must cont ain the two ozone precursors: oxides of nitrogen (NOx) and reactive organic gases (ROG) . (The terms, ROG and VOC (volatile organic compounds), are used in terchangeably in this documen t.) For the PM2.5 SIP, the emission inventory must contain directly emitted PM2.5 and PM precursors: NOx, ROG, sulfur oxides (SOx), and ammonia (NH3).

Emission Inventory Overview

Basic Elements of the Emission Inventory

An emission inventory is a critical tool in t he evaluation of air pollution. Very simply, an emission inventory is a system atic listing of the sources of air pollution along with the amount of pollution emitted from each source or category over a given time period.

Emission inventories are an esti mate of the air pollution emissions that are actually released into the environment—they are not m easurements of ambient concentrations. The following are examples of pollu tion sources by key sectors:May 7, 2007 Appendix F 3 • Industrial sources—power plants and oil refineries;

• Area-wide sources—consumer products and residential fuel combustion for heating homes;

• On-road sources—passenger vehicles and heavy-duty trucks;

• Off-road mobile sources—aircraft, trains, ships, recreational boats, construction equipment and farm equipment; and

• Non-anthropogenic (natural) source s—biogenic (or vegetation), geogenic (petroleum seeps), and wildfires.

The first four sectors listed are examples of anthropogenic, or human caused, emission

sources. California’s statewide emission inventory includes over 17,000 individual facilities (or point sources) where business a ddresses are specifically identified. These facilities comprise approximately 14,000 process/industry types.

The emission inventory also includes approx imately 450 area-wide source categories. The area-wide source categories include aggregated point sources, or facilities, that are not inventoried individually but are es timated as a group and reported as a single source category, for example, gas stat ions and dry cleaners. Area-wide sources typically are associated with human activi ty and take place over a wide geographic area. Consumer products and unpaved road dust are additional ex amples of area-wide sources. The complete methodologies fo r these and all area-wi de source categories

can be found at: http://www.arb.ca.gov/e i/areasrc/areameth.htm

.
The mobile source emission inventory is developed by ARB’s emission factor models -

EMFAC and OFFROAD. EMFAC estimates on-road emissions from all on-road motor vehicles, from passenger cars through heavy duty diesel trucks, and groups them in 250 categories (or technology groups). Off- road categories include emissions from all vehicles and equipment that operate off-road wh ich includes aircraft, locomotives, lawn and garden, cargo handling, construction, and ships and harbor-craft. OFFROAD groups these equipment into 1300 categorie s. For each category in EMFAC and OFFROAD, emissions are given by emi ssion mode (e.g. running exhaust, starts, evaporative losses, and tire and brake wear).

Non-anthropogenic sources genera lly include source categories with naturally occurring emissions such as wildfires and geogenic sources (e.g., petroleum seeps).

Agency Responsibilities

ARB works jointly with the thirty-five local air pollution control and air quality management districts (districts) to devel op a comprehensive statewide emission inventory. Districts are responsible for devel oping emission estimate s for major facilities (point sources) in their jurisdictions by work ing closely with facility owners. Districts are also responsible for developing emission es timates for approximately one-third of the non-point (or area-wide) sources.May 7, 2007 Appendix F 4 ARB is responsible for developing the mob ile source inventory (both on-road and offroad sources) and the remaining two-thirds of the area-wide sources. ARB works with other state agencies including t he California Department of Transportation (CalTRANS), the Department of Motor Vehi cles (DMV), and local councils of government (COGs) to assemble motor vehicle activity information necessary for the mobile source emission

estimation models. To estima te emissions for the remainin g two-thirds of the area-wide sources, ARB works jointly with State agencies, such as the Department of Pesticide Regulation (DPR) which develops the em ission estimates for pesticides and the California Energy Commission which mainta ins power production and energy demand data that are critical for estimating futu re emissions growth from power plants.

Pollutants and Precursors

California’s ozone attainment strategy is to reduce emissions of ozone precursors – NOx and VOC. The strategy for reduc ing PM2.5 focuses on reducing NOx.

Oxides of Nitrogen (NOx)

NO
x from anthropogenic sources occurs primar ily when fossil fuels are combusted at high temperatures. The table below shows that in 2006, 85 percent of NO
x emissions in California are generated from mobile sources su ch as cars, trucks, buses, aircraft, and trains, while area-wide and st ationary sources contribute the remaining 15 percent.

References ii and iii provide

information on the differences between ROG and VOCs.

The primary anthropogenic sources of ROG in California, as shown in the table below,

are on-road mobile which includes exhaus t, fuel evaporation, and incomplete fuel combustion, and area-wide sources which includes solvents from dry-cleaning, degreasing, and coating operations.

Particulate Matter (PM2.5)

Particulate matter (PM) is a complex mixt ure of varying sized particles and liquid droplets including components such as acids, organic chemicals, metal, and soil or dust. There are two types of PM: primary and secondary. Prim ary PM is emitted directly from a source, such as unpaved ro ads, fires, and demolition or construction sites. Secondary PM is formed by complex reactions in the atmo sphere with chemicals such as sulfur and nitrogen dioxides. The majo rity of “fine particl es” (PM2.5) is formed by these complex reactions. A subset of PM 2.5 of particular concern are those that are emitted by diesel engines.May 7, 2007 Appendix F 6 2006 Statewide Emission Inventory – PM2.5

Geographic Considerations

In California, the emission inve ntory is constructed at the district, air basin, and county levels. This provides the flexibility needed to meet the jurisdictional requirements of local and State governments wh ile addressing the spatial aspec ts of air quality issues.

In cases where nonattainment areas do not line up with these geographic boundaries, ARB further resolves the inventory to estima te the portion of emissions that occur within nonattainment area boundary lines. This is d one by selecting only the point sources

that fall within the nonatta inment area boundaries, and estimating the emissions

contribution of each area-wide and mobile source category to the nonattainment area.

California recently approved the state wide Emission Reduction Plan for Ports and

Goods Movement that ext ends the off-shore boundaries fo r estimating the emission impact from shipping activities, thus lead ing to a modification in the geographic accounting of the off-shore emi ssions in the inventory. Forme rly, only marine emissions occurring within a 3-mile range were included as part of California’s emission inventory. The SIP emission inventory now includes emissi ons from shipping activities out to 100 miles. In the new definition, emissions occurring within thr ee miles of the shore line are assigned to the nearest air basin (e.g., emissi ons occurring within three miles of the Los Angeles County shore line are assigned to Los Angeles County in the South Coast Air Basin). Emissions occurring outside the 3-mile boundary are assigned to the Outer Continental Shelf Air Basin, but are still associated with the responsible county and district (e.g. the emissions occurring out side of the 3-mile boundary of Los Angeles County would be assigned to the Outer Cont inental Shelf Air Basin and would be the responsibility of the South Coast Air District).May 7, 2007 Appendix F 7 Base Year Inventory Selection for the SIP

The SIP is based on emission projections that are linked to a base year inventory.

U.S. EPA identified 2002 as t he emission inventory base y ear for the 8-hour ozone and

PM2.5 SIPs. This selection was announc ed by memoranda to the States in November 18, 2002 2

.

Emission Estimation Concepts

The key to the emission inventory is found in what is termed the “emission process”. The emission process defines the fundamental level at whic h emissions are calculated, stored, and maintained in the inventory. The total emissions for each emission process are calculated by applying a process rate (i.e., the number of emission activity units) to the emission factor (i.e., the amount of emissions per activity unit).

In principle, this simple concept holds for all emission sectors (i.e., point, area-wide, on-road mobile, and off-road mobile). Differe nces lie in the method or approach used to derive the process rate and emission factors. For example, the emissions from a power plant could be calculated by applying an emis sion factor (pounds of emissions per megawatt-hour) times the number of megawatt- hours of electrical energy generated. The emissions from the light -duty passenger car fleet could be calculated by applying an emission factor (grams of emissions per mile traveled) times the total vehicle miles traveled (VMT) for that mobile category. It should be noted that the examples above are simplified—particularly for on-road and off -road emissions. These emission factors are specific to model year, technology and f uel type, and are adjust ed for temperature, humidity, and operat ing speed.

Emission Forecasting Overview

Emissions forecasting depends on two independent variables: growth and control. For stationary sources, socioeconomic growth profiles are developed and linked to the inventory via the inventory pr ocess and/or industry types. For example, power plant growth is estimated based on the combined e ffects of economic growth in the sector along with the projected energy utilization by the California Energy Commission (CEC). Growth for consumer products is estimated by population growth at the county level. These growth profiles are constructed for t he entire timeframe addressed in the SIP.

The California Emission Forecasting System (CEFS) includes growth data for the period 1990–2030 for SIP forecasting exercises. Sim ilarly, control profiles are constructed to reflect adopted emission control measures. A c ontrol profile is developed that describes the implementation of the rule and the profile is included as part of the baseline CEFS forecasts. CEFS projections are run for the entire Stat e by applying the growth and control profiles to the 2002 base year inventor y to obtain the projections needed for SIP analysis.

EMFAC and OFFROAD do not use a base y ear projection approach. Rather, the emission models employ sophistic ated routines that predict vehicle fleet turnover by vehicle model year. As with stationary sources, EMFAC and OFFROAD include controlMay 7, 2007 Appendix F 8 algorithms that account for all adopted regulatory actions (e.g., an amended emission standard to be implemented by a certain y ear, or increased stringency on a roadside inspection program to be implemented in a fu ture year) which, when combined with the fleet turnover algorithms, pr ovide baseline projections.

CEFS integrates the projected inventorie s for stationary and mob ile sources into a single database to provide a comprehensiv e statewide forecast inventory.

Nonattainment area inventories are extracted fr om this comprehensive inventory. This establishes the baseline projections from whic h the SIP inventory is constructed. The

data are accessible to ARB and district planners via user-friendly web reporting tools.

Types of Inventories (Annual Average, Seasonal, Modeling)

Annual Average

Annual average emissions data by major source category in tons per day are derived from a simple average by ta king the annual emissions reported (or estimated) in tons per year and dividing the emissions by 365 days.

Seasonal Inventories

Summer and winter planning emissions take in to account the temporal variation (e.g. activity variation) of emissions at a facilit y or a source category throughout the year. This is accomplished by collecting throughput or activity data from point source facilities where available, and developing temporal prof iles for area sources to estimate monthly

variation of the emissions. CEFS calcul ates summer and winter planning emissions based on these temporal data. The summe r planning season for California is MayOctober, and the winter planning season is No vember-April. (Note: U.S. EPA assumes a shorter summer planning period (June-August) in its temporal data collection schema.) California requires planning ev aluations to be based on a longer summer because it experiences longer periods in which temperatures are warm enough to

contribute to ozone formation than most othe r states). The summer season planning emission inventory is used in ozone SIP planning.

Modeling Inventories

CEFS also generates emission inputs for ph otochemical modeling exercises. The categories handled by CEFS are stationary, area-wide and off -road mobile sources. (Note: Modeling emissions for the on-r oad sector are generated with EMFAC/DTIM, and these modeling inputs are handled outside of CEFS.) Modeling inventories are month/day-specific estimates that are tempor ally and spatially resolved at a finer level than planning inventories—CEFS calculates emi ssions for a typical weekday or a typical weekend day based on weekly oper ation profiles identified for t he emissions processes.

Point source locations are identified in CE FS by the Universal Transverse Mercator (UTM--North American Datum (NAD83) ve rsion) geographic coordinate system. Modeling inventory projections include facility level emissions at the facility, device, and process level with stack locations and associ ated flow characteristic as applicable.

Area source emissions are maintained at the county level and are further resolvedMay 7, 2007 Appendix F 9 based on spatial surrogates as a post-proce ssing step prior to modeling. The day specific emissions are generated for ty pical weekday and weekend periods.

Planning and Modeling Inventory Differences

The temporal information used to determine s easonal planning inventories is also used to develop month/day-specific modeling inventories—the data are just further resolved for modeling inventories. It should be not ed that modeling inventories generated by CEFS are not actual day specific emissi ons based on field studies—they are estimates of emissions for “typical” oper ating conditions. In some cases, “actual” day-specific

information is available and this can be used to overwrite the results of the CEFS emission modeling inventory output s. It is important to note that because modeling inventories are month/day-s pecific, the emission numbers will not match the planning inventory emissions.



### 2. Emission Inventory Improvements

Overview

ARB devotes substantial effort to continually im prove the emission in ventory. Updates to the inventory occur through three proce sses: planning and development, regulatory support, and special studies. The new information acquired and methodologies developed are folded back into the models as well as the methodologies for sources not previously included. This is a dynamic process and ARB will continually work to improve its methodologies through research and stakeholder feedback.

Improvement Process

Planning and Development - SIP

The planning process is undertaken to develop st rategies for meeting air quality goals. The SIP inventory is the cent erpiece data element for determining future attainment in photochemical modeling exercises, and the basis for defining control strategies.

Regulatory Support

The regulatory process identifie s potential emission reductions. This typically involves new surveys to gather the most up-to- date data (e.g. equipment activity and populations). These improved data allow for more accurate emission estimates and identify key areas where reductions can be achieved. The planning and regulatory processes are also used to solicit peer review and stakeholder input.

Special Studies / Research

Another mechanism through which improvement s are made is special studies. These studies may or may not be associated with t he SIP or regulatory support processes but

are used to further the underst anding of emission modeling an d verification. Special studies include funding or participating in cutting edge research projects, developingMay 7, 2007 Appendix F 10 innovative emission inventory methodologies, and collaborating with industry, academia and the public to better understand emissions proc esses. Examples of special studies include, but are not limited to, Southern California Ozone Study and Central California Ozone Study related research. The results from these projects have provided data that

allow validation checks between obs erved air quality and emission trends 3 , and

emissions associated wit h air quality exceedances 4

.

Stakeholder Outreach

ARB works jointly with other State agencies, districts, and stakeholders to develop a comprehensive emission inventory on an annual basis. Comprehensive inventories are submitted triennially and partial inventorie s are submitted annually to U.S. EPA for the National Emission Inventory 5 (NEI). ARB also publishes the most current emission inventory in the annual Almanac of Emissions and Air Quality 6

.

Quality Assurance/Qua lity Control (QA/QC)

QA/QC is a formal process focused specific ally on ensuring the in tegrity and accuracy

of the inventories for the California 2007 8- hour ozone SIP and PM2.5 SI P in California. ARB formally initiated this comprehensiv e effort in September 2004 through its Emission Inventory Technical Advisory Committ ee (EITAC). This st arted an iterative process of continual updates to the 2002 base year emission inventory for stationary point and area-wide sources (including growth and control data), leading up to the

finalization of the SIP inventor y. In addition, ARB emission in ventory staff worked jointly with the ARB’s modeling staf f through the Gridded Emission Coordination Group that includes district modeling st aff and industry representatives . A principle aim of this group is to provide a critical feedback loop to emission inv entory staff to ensure that inventory inputs have been reliably prepared for use in photochemical modeling.

The statewide emissions inventories are assembled and maintained by ARB in the California Emission Inventory Devel opment and Reporting System (CEIDARS) and California Emission Forecasting and Planni ng Inventory System (CEFS) databases. Before an emission inventory is approved, a series of checks are performed to assure

that the correct statewide emissions estima tes are reported. Upon completion of the models, various scenarios are run to provide emissions by county, ai r basin, district, EIC code, pollutant, calendar year, and season. Queries are then run on these scenarios to provide the statewide emission totals by pol lutant and year. Finally, as a check to

ensure that what CEFS estimates as st ate totals match what EMFAC/OFFROAD estimates, the CEFS queries are matc hed against EMFAC/OFFROAD model output.

Inventory verification 7 is another important step to ens ure the accuracy of the emission inventory. Since 1987 t here have been a number of studie s that have contributed to model development. In these tests, emissi ons from vehicle fleets are compared to output for similar fleets calc ulated from the EM FAC model. Comparisons have been made between EMFAC fuel consumption estimate s and actual fuel sales for that fleet reported by the State Board of Equalization, and emissions derived from fuel sales and remote sensing data.May 7, 2007 Appendix F 11 Specific Category Improvements

Stationary

Methods for estimating emi ssions from industrial point sources have continually improved as district staff work with facility owners to ensure that reported emissions are real as opposed to permitted (or potential) values. The California Clean Air Act Fee Regulation imposes fees on large permitted point sources thus encouraging facility owners to report the most accurate emissi ons possible. ARB audits the district emission inventory programs on a planned cy cle to further ensure that emission inventory program requirements are met.

Area-wide

New survey data for consumer products and architectural coat ings improve the aggregated inventory estimates as well as a be tter characterization of emissions at the product type. Currently there are 152 consum er product categories and 56 architectural coatings categories - the 1994 SIP inventory only had three categories each. The same is true for degreasing categor ies - the 1994 SIP had only five categories and the current inventory now has 32 categories. Im provements have also been made to the agricultural industry categories as a resu lt of a partnership between ARB and the agricultural community. ARB participates in an ad-hoc agricultural advisory committee to approve methods used for estimating base year emissions and future year growth and control assumptions for forecasting. T he methodologies for the following categories have also been updated: auto refinishing, in dustrial coatings and solvents, livestock husbandry, pesticides, waste burning, wildland fire use, ammonia, and wineries. The most recent improvements to the area-wide emission inv entory sectors are described

below:

 Ammonia A comprehensive 2002 ammonia inventory wa s developed for all area-wide sources (in addition to on-road, off-road, and natural sources). The emissions were calculated using data provided in repor ts by ENVIRON and the NASA Ames Research Center.

 Architectural Coatings In response to the California Clean Air Act F ee Regulation, several architectural coating

manufacturers submitted revi sions to their 2001 survey dat a (calendar year 2000 sales). The changes in sales volume and emissions were applied uniformly across all categories.

 Auto Refinishing This category was updated using data from a 2001 ARB survey and the emissions were grown to 2002.

 Consumer Products Two sets of changes have been incorporated in to the consumer products inventory. First, manufacturers submitt ed revisions to their 1997 survey data in response to the California Clean Air Act Fee Regulation and resulted in updates for 13 categories. Next,May 7, 2007 Appendix F 12 results of the 2001 Consumer Products Survey have been incorporated. Some categories have been expande d and several new categories have been added.

 Industrial Coatings and Solvents

The emissions for several of thes e categories have been updated using the U.S. Census Bureau’s 2002 Industrial Repor t for Paint and Allied Products. The nationwide consumptio n data were apportioned to Calif ornia using manufacturing employment data for the industry sectors likel y to use the specific types of industrial coatings.

 Livestock Husbandry ARB published a new methodology in 2004 for estimating ROG emissions from livestock facilities including dairies, feedl ots, poultry operations, and other confined

animal facilities. The met hodology also includes PM estima tes for dairies and feedlots. The emission estimates are based on animal popu lation data from the year 2000. ARB uses district-specific data where avai lable and employs a generalized methodology where data are lacking. For permitting purposes and to more fully reflect the processspecific livestock emissions, the San Joaquin Valley Air District has adopted livestock

emission factors that differ fr om the ARB default values.

 Pesticides The pesticide inventory includes the emissi ons from agricultural and structural applications. Updated emissions for 2003 are calculated using information from the annual Pesticide Use Report (PUR) database and pesticide product emission potential (EP) data maintained by the Ca lifornia Department of Pesticide Regulat ion (DPR). The EPs that are assigned to the products ar e either measured by thermogravimetric analysis (TGA), calculated by DPR chemists, or assigned a default value equal to the

median TGA-based EP in each formulation ca tegory. Prior to 2002, DPR assigned EP values to products with no measured values as the maximum TGA in that category. The

use of median rather than maximum TGA values has resulted in a significant lowering of ROG emissions for pesticides with default em ission values. The average 2003 TOG and ROG emissions from all agricul tural and structural pesticides were 55 percent lower in 2003 than in 1995. The most significant reducti on was in the structural methyl bromide category, likely due the Montr eal Protocol, which mandates the phase-out of methyl

bromide.

 Waste Burning

Emissions result from t he waste burning of agricultural residues, weed abatement, range improvement, and other materials. Al though this is a district-reported category, ARB has developed default 2002 emission esti mates for several dist ricts that have not provided updates in recent years. Updated emissions data have been developed for the following areas: South Coast Air Basin, Mojave Desert Air Basin, San Diego Air Basin, Salton Sea Air Basin, Amador C ounty, and Western Nevada County. There have been no changes to the under lying methodology for calculating emissions. The

emissions are based on distri ct-reported burning activity. Emission factors and fuel loading values have been expanded to in clude more specific crop types.May 7, 2007 Appendix F 13  Wildland Fire Use (WFU) A WFU is a naturally ignit ed lightning fire that is m anaged for resources benefit. The WFU emission inventory category was created in 2004, and inventory back-populated to

1994 where data were available. WFU emissi ons are calculated using the Geographic Information System (GIS) bas ed Emission Estimating System model developed for ARB by UC Berkeley’s Center for the A ssessment and Monitoring of Forest and Environmental Resources laboratory.

 Wineries This is a newly updated methodology for wi ne fermentation emissions. The emission

factors for wine fermentati on have not been updated from the older methodology, but the source of wine fermentation activity has been updated. The Tax and Trade Bureau (TTB) is now the source of estimates for amounts of wine ferment ed in the state. Temporal data gained from the TTB records allow us to give detailed monthly breakouts

of wine fermentation in the state.

Mobile

ARB is continually improving EMFAC and O FFROAD, and emission inventory elements as represented in each model. The following discussion includes evolution of EMFAC and OFFROAD, inventory verification, and improvements made for EMFAC2007 and

the SIP.

On-road

The following are modifications to the model and the inventory since the last SP. For a more thorough technical explanation please refer to the tech memos at http://www.arb.ca.gov/msei/msei.htm, and http://www.arb.ca.gov/msei/ onroad/previous_version.htm . The changes below are those changes reflected in EMFAC2007 t hat have occurred since EMFAC2002.

 Revisions to the Methodology used to C haracterize the On-road Vehicle Fleet Vehicle population data by class, age and geographic area used in EMFAC are based on the Vehicle Registration Database maintai ned by the California Department of Motor Vehicles (DMV). EMFAC back-casts histor ic changes in vehicle population using the oldest DMV data available, and forecasts fr om the most recent . As new data are received, projections are replaced with act ual data. EMFAC2007 population estimates were updated based on 2000-2005 data.

 Modification of Mileage Accrual Rates Previous mileage accrual rates were based on Smog Check data acquired from 1991- 1995. To more accurately model vehicle mi les traveled, the new model incorporates data from Bureau of Automotive Repair (BAR) 2001-2003 for the following gasoline powered vehicle classes: passenger cars, li ght-duty trucks (Tiers 1 and 2), mediumduty trucks, light heavy-duty trucks (Tier 4 and 5), and motor homes.May 7, 2007 Appendix F 14  Updating Vehicle M iles Traveled and Speed Distributions Vehicle miles traveled and speed distributio ns were submitted by transportation planning agencies for the South Coast, t he San Francisco Bay Area, and San Diego

and Santa Barbara Counties and used to update EMFAC.

 Modifications to the Inspection Maintenance Programs

Modifications were made to reflect the c hanges in inspection and maintenance (I&M) programs for areas that upgraded to the enhanced Accelerated Simulation Mode program and change-of-ownership exemptions.

 Ethanol Permeation In the prior EMFAC, evaporative emissions were correlated to oxygen content. Evaporative emissions from me thyl-tert-butyl ether (MT BE) and ethanol (EtOH) were

assumed to be similar since both contained two percent oxygen. Because recently completed studies indicate that EtOH has much higher permeation rates through fuel tank walls, hoses and fittings, EMFAC was m odified to reflect these findings.

 Revision of Heavy Heavy-Duty Die sel Truck Emission Factors and Speed

Correction Factors New chassis dynamometer te sting data developed throug h the CRC E55-59 program were analyzed and integrated into EMFAC. Emi ssion factors for this category reflect all

available data from CRC as well as other data sets. These data were used to develop new emission factors and speed correction fact ors. New tampering, mal-maintenance and malfunction survey data were used to update deterioration rates, demonstrating that heavy heavy-duty diesel tr uck emissions are greater t han previously estimated.

Trucks were for the first time tested over an ARB- developed heavy-heavy-duty test cycle, generating idle emissions data covering a wide span of model years as well as emission data at several different speeds and idle. These new data have been adopted by ARB and used to generate new emission factors and new speed correction factors.

 Redistribution of Heavy Heavy-Duty Die sel Truck Vehicle Miles Traveled in

California Vehicle miles traveled estimates are provided by the transportation planning agencies, but ARB is responsible for t he distribution of that VMT by vehicle class and region. Heavy duty diesel truck VMT in EMFAC2002 was allocated based on truck registration. This method is appropriate for light duty v ehicles and heavy duty gasoline trucks, but heavy heavy-duty diesel trucks travel extensivel y outside their registration counties. VMT was redistributed in EMFAC2007 using survey information from the California Department of Transportation (CalTrans) and modeled from MVSTAFF, an annual report by CalTrans. The new distribution more accurately reflects actual truck travel patterns in California.

 Revised Break Wear PM Emission Factors

EMFAC has been modified to account for tr ue brake counts. Previously a single emission factor for brake wear, based on a 1983 study, 8 was used to calculate the

amount of airborne dust attributable to break wear (12.8 mg/mile). This emission factorMay 7, 2007 Appendix F 15 assumed that all vehicles were equipped with four brakes, even if the vehicle had more

than four brakes.

 On-road Fuel Correction Factors

Fuel correction factors are used to reflect the impact on emissions of commercial fuels compared to the fuel used duri ng the certification process. Modifications to the fuel correction factors (FCFs) were incor porated into EMFAC2007 for both diesel and gasoline. For example, the FCFs for P hase II reformulated gasoline (RFG) were modified for the 1996-2003 calendar years to be cumulative to the Phase I (1992-1995 calendar years) values. Additionally, the impacts of ethanol on evaporative processes, changes in sulfur and aromatics composition in fuel, exhaus t hydrocarbon benefits for clean diesel, and an out-of-state di esel fueling rate of 10 per cent were incorporated.

 Revised Planning Humidity Profiles Meteorological conditions impact the emissions process in vehicles, therefore, EMFAC2007 incorporates ambient rela tive humidity profiles to determine NO
x conversion in exhaust as well as air condi tioner usage by automobile drivers. Previously, EMFAC used annual average daily rela tive humidity profiles for each county or geographical area in the State. EM FAC2007 now incorpor ates hour-by-hour temperature, relative humidity, and ozone conc entration data from 700 stations for the years 1996-2004.

 Revised Planning Tem perature Profiles EMFAC2007 contains daily ambient tem perature profiles for use in evaluating evaporative emissions and other heating/cooling related proce sses. In the previous EMFAC, hourly temperature observations co llected on high ozone days were spatially distributed by zip code and weighted by popu lation. The resulting weighted profiles seemed rather cool. Weighting in EMFAC2 007 is done by vehicle miles traveled (VMT) and provides more representat ive temperature profiles.

 Corrections to Heavy-duty Gas Cap Benefits In reviewing the gas cap benefits staff not iced reductions on hydrocarbon emissions were negligible for heavy duty gas oline vehicles. Further review revealed the gas cap benefits were not fully implem ented in EMFAC. In EMFAC 2007, the gas cap algorithm has been implemented for heavy duty vehicles.

 Coding Corrections Several coding errors have been corrected which results in a minor change to

emissions estimates.

Other Mobile

The following measures are reflected in OFFR OAD2007 or the external modules. For a more thorough discussion on improvements to the other mobile inventory, please refer

to the tech memos at http://www.arb.ca.gov/msei/msei.htm

.May 7, 2007 Appendix F 16  Addition of Tier 4 Emission Factor s to Off-Road Large Compression Ignition Engines (>25 hp)

The previous OFFROAD model only provided emission factor s based on Tier 0, 1, 2 and 3 emission standards for compression-ig nited engines greater than 25 horsepower (hp). In 2003, Tier 4 emission standar ds were adopted by ARB and the OFFROAD model has been updated to incorporate these new standards.

 Off-road exhaust emissions invent ory fuel correction factors

Fuel correction factors have been modified to be consistent with EMFAC and to take into account current reformulated gasoline im pacts. Carbon monoxide fuel correction

factors for summertime and win tertime fuel which vary geographically, and the benefits of ultra low sulfur diesel (requirement commencing in 2007) were applied.

 Addendum to Evaporative Emissions

The current version of t he OFFROAD model includes an updated estimate of the evaporative emissions from large spark-ignited engines, including those used in recreational marine applications.

 Revisions to the Diesel Transport Refri geration Units (TRU) Off-road Inventory

TRU emissions are calculated in the OFFROA D model as a function of emission rate, population, activity, average horsepower, and l oad factor. With th e exception of the emission rates, all other factors were based on the 1997 Power Systems Research (PSR) report. Since late 2002, ARB has obtained more up-to -date population and activity estimates from surveys of TRU manuf acturers. These results have revised the input factors of population, activity, load factor, average horsepower , growth factors, survival rates, and useful lifetime estimates to the OFFROAD model.

 Estimation of the Impact of Ethanol on Off-Road Evaporative Emissions Since the phase out of methyl-tert-butyl ether (MTBE) as a gasoline additive in 2004 ethanol (EtOH) has been used as an additive to meet the required two percent oxygen content in commercially dispensed gasoli ne. Because MTBE and EtOH both contained two percent oxygen, their evaporative emissions were assumed to be similar. However, recently completed studies indicate this is not a correct assumption. These tests

indicate that EtOH has much higher permeation rates through fuel tank walls, hoses and fittings. OFFROAD2007 refl ects these findings.

 Recreational Marine Growth factors and engine-to-boat ratios were updated with more recent DMV and

National Marine Manufacturers Association (NMMA) data. Additionally, evaporative emissions are separated into ope rating and storage emissions.

 Agricultural Based on findings from the Agricultural Advi sory Committee, grow th factors for the San Joaquin Valley were updated.May 7, 2007 Appendix F 17  Recreational Vehicles

The OFFROAD model has been modified to a ccount for updated population for MC, All Terrain Vehicles (ATVs) and snowmobiles us ing Department of Mo tor Vehicles (DMV) calendar year 1991-2005 totals. Human popul ation data from Census 2000, personal income, and median household income data from Department of Finance were also applied to develop the growth rate for recrea tional vehicles. DMV 2005 registration data has been used to update county allocation factors. In addition, DMV registration also shows the inactive population for MC, AT V and snowmobile. Thus, the diurnal and resting emissions for inactive population fo r these three equipments are included in the OFFROAD2007. Also, the activity and load fa ctor for snowmobile were updated to be

the same as U.S. EPA’s NONROAD model. Activity results from U.S. EPA’s NONROAD model for specialty vehicles, benefits of golf ca rts and specialty vehicles subject to small off-road engine and large spark ignition (LSI) controls, benefits of snowmobiles subject to the U.S. EPA’s capping standard, and the addition of OFMC and ATV evaporative emission factors as grams per mile were calculated in

OFFROAD2007.

Although the overall statewide emissions fr om recreational vehicl e are the same, the

distribution of emissions to the specific county/air bas in/air district has been changed relative the location where the equipment is stored or operated. The storage allocation is relevant to the diurnal and resting emi ssions from active and inactive recreational vehicles and is based on the county of DMV registration. The operational allocation applies to exhaust, hot soak and running lo ss emissions and represents where the

off-road trails are located.

 Construction and Ground Service Equipment (D> 25 horsepower) The OFFROAD model was updated with population, useful life, age distribution, annual activity, growth data and a deterioration rate cap introduced based on the 2003 McKay & Co. Study, ARB’s 2005 Off-Road Diesel In -Use Equipment Survey, ARB’s 2006 OffRoad Diesel In-Use Mini Survey, 2003 TIAX Su rvey of Public Fleets, and input from industry and stakeholders in public workgroup meetings and workshops.

 Small Off-Road Equipment (SORE) The OFFROAD model was updated with: new exhaust and evaporative standards; new population and activity estimates for resi dential lawn and garden equipment obtained from the Lawn and Garden Survey; new populat ion estimates for commercial lawn and garden equipment from an ERG su rvey; and modified small off-road engine survival rate curves using information from the Ou tdoor Power Equipment Institute.

The following changes were ma de to external modules:

 Changes to the Locomotive Inventory Locomotive growth factors were revised in the OFFROAD model based on new data that better reflected locomotive operations , including projected growth in intermodal freight traffic, both domestic and internatio nal, U.S. industrial production, and various

railroad statistics available from the Associat ion of American Railroads (AAR). OtherMay 7, 2007 Appendix F 18 measures such as the 1998 South Coast and 2005 State memorandum of understanding were also reflected.

 Cargo Handling Equipment A separate methodology for cargo handling equipm ent at the ports and inter-modal rail yards per the Cargo Handli ng Equipment Air Toxic Cont rol Measure (December 2005) was incorporated.

 Ocean Going Vessels The OGV inventory reflects updated populat ion and activity data for ocean-going

vessels statewide. The emission estima tes were developed for main and auxiliary engines in eight vessel types (auto carrier , bulk cargo, container, general cargo, passenger, reefer, roll-on roll-off and tankers) . In addition, methodology was developed

to allocate statewide emissions to indivi dual ports and districts. The ARB regulation requiring vessels with auxiliary engines to swit ch from heavy fuel oil to marine distillate

within 24 nautical miles of California was incorporated into the inventory.

 Commercial Harbor Craft The commercial harbor craft inventory was re vised with a single statewide approach.

OFFROAD emission factors were used to ca lculate emissions and adjusted to better reflect the “E3” test cycle which is more representative of marine engines.

 Portable Fuel Containers/Gas Cans Emission estimates were developed from data such as percentage of household/businesses with cans, average cans per household/business, average volume of cans, and refill frequencies collected during two surveys in 1998 and 2004. Allocation factors and growth rates fo r residential gas cans are based on the Department of Finance's Census 2000 dat a and landscaping employment growth projected by EDD (Calif ornia Employment Devel opment Department).

Biogenic

After its original application to the S outhern California Ozone Study domain, the biogenic emission inventor y GIS (BEIGIS) model was expanded to the Central California Ozone Study/Californi a Regional Particulate Air Quality Study domain. In order to represent central and northern California conditions during summer and winter seasons, the BEIGIS model has incorporated fu rther inputs, such as crop Geographic Information System (G IS) data for central and northern California developed by the California Department of Water Resources (DWR). Because it is a statewide land use/land cover database, the Gap Analysis Pr ogram (GAP) is still used to represent natural areas in the model. Urban vegetati on survey data for Fresno, Oakland, and Sacramento were compiled from several studies and used to develop urban land use biogenic volatile organic co mpounds (BVOC) inputs for other urban areas in the central and northern California portion of the model. Crop BVOC and leaf mass factors for additional crops listed in DWR crop GIS databas es were compiled from literature. Crop calendars developed by the Univ ersity of California-Davis Department of AgriculturalMay 7, 2007 Appendix F 19 and Resource Economics were consulted in order to develop growing season and dormant season crop BVOC inpu ts. In-leaf and off-leaf season BVOC profiles were also developed for natural and urban areas, in order to account for the presence of deciduous and evergreen specie s in landscapes. A 1 km 2 resolution winter Leaf Area Index (LAI) raster derived from Adv anced Very High Resolution Radiometer ( AVHRR)

satellite data 9 was used in order to account for winter dormancy in natural areas and croplands.

Emissions Estimation Methods

Stationary Emissions

Stationary emission sources identified on an individual basis or a single source are called point sources. Emissions from point sources are estimated from facilities that emit more than ten tons per y ear of any criteria pollutant. They are identified by name and location. A facility may have many indivi dual, identifiable sources of emissions or (points) of emissions. For example, a coffee processing facility may have a boiler, roaster, grinder, and packing station as emissi on points. In addition , a point source may have one or more processes or operation. For example, a boiler burning natural gas part-time and oil part-time is considered to have two processes because emission rates

are different for the two fuels.May 7, 2007 Appendix F 20 The emissions for each point are computed as t he product of use factor (an indicator of the extent of the activity per unit time) and an emission factor (the quantity of pollutant emitted per unit of the use factor). Point s ource use factors usually relate to a process rate, such as the amount of fuel oil consumed in a boi ler or the amount of asphalt concrete produced at a batch plant. T he general equation used to calculate the

emissions is shown below:

EMS =PR x EF x CONV

Where: EMS = Emissions (tons/year)

PR = Process Rate or activity data in (SCC unit/year)

EF = Emissi on factor (mass/SCC unit)

CONV = Unit conversion factor

Emission factors are derived from tests that relate emissions to the process causing the emissions. When adequate source test data are available for a source, these data are

used to derive emission factors for the em ission calculations. When adequate source

test data for a source are not available, an alternative is to use average emission factors for similar emitting sources. These factors are usually derived by averaging the results of many tests of similar sources. Such factors are published by federal U.S. EPA in Compilation of Air Poll utant Emission Factors . The published emission factors in AP-42 are usually calculated for devices without control equipment. Because controls may very among different facilities, it is therefor e necessary to adjust th e emissions factors to account for the specific control equipment being used.

In the base year emission inventory, cont rolled emissions are estimated by applying control efficiency factors to the “uncontro lled” emissions. These base year control factors take into account operational upset s and equipment malfunctions that lead to excess emissions. The resulting “controlled” inventory represents the actual emissions

that have occurred over the 365 day calendar year. Due to the wide variation in how districts account for these operational fluctu ations, rule effectiveness is not accounted for as an explicit reporting variable in CEIDAR S, rather, rule effectiveness is treated as an implied variable maintained by the districts as part of the actual “controlled” emission

estimates that are submitted to ARB.

In some cases, it is possible to determi ne emissions using a materials balance which

reconciles the amounts of materials that ent er and leave a process. This method is used for many sources, such as painting proc esses, where it is assumed that all the solvent used in the coating eventually evaporates.

The source information along with activity data and emission factors used to calculate emissions for all point sources are kept in district’s files and are reported to ARB on a regular basis (generally once a year).May 7, 2007 Appendix F 21 Data Acquisition

Information on emissions from stationary source s is obtained primarily from the districts which have primary responsib ility under state law (Health and Safety Code section 40000) for regulation of stationary sources of air pollution.

In developing the emission inv entory, there is considerab le interaction between ARB and the districts. The planning process fo r an inventory development starts with the assessment of needs and require ments. Following the init ial inventory planning, ARB

collaborates with districts to prepare inventory developme nt schedules and updates to the inventory.

Area-wide Emissions

Area source methodologies are used to calc ulate emissions from aggregated point

sources and area-wide sources. Aggregated point source s are many small point sources, or facilities, that are not inventoried individually but are estimated as a group and reported as a single source category. Examples include gas stations and dry cleaners. Because many of these sources ar e already accounted for as facilities or point sources (see the previous section on Stationary Emissions), the area source emissions are reconciled with point emi ssions before being added to the emission inventory. For example, the area source methodology for dry cleaners is used to calculate the total emissions for a particula r county. These area source emissions are then reconciled by subtracting the emission s for dry cleaners already accounted for in the point source inventory.

Area-wide sources include source categor ies associated with human activity and emissions take place over a wide geographic area. Consumer products and unpaved road dust are examples of area-wide sources.

Both ARB and districts share responsibility in updating t he various area-wide source categories. Some categories are the responsib ility of the district while other categories are ARB’s responsibility. ARB methodologie s and many of the dist ricts methodologies can be accessed at http://www.ar b.ca.gov/ei/areasrc/index0.htm.

Data Acquisition

When ARB develops an area-wide source me thodology, many possible sources of activity data and emission factors are cons idered. Often data are obtained during the development of regulations. For example, in developing consumer product regulations, ARB routinely conducts statewide surveys. Research studies, some of which are sponsored by ARB, are another source of emissions data. Finally, various state and federal agencies may have relevant data needed to estimate emissions.

If activity data are not available at the county level, then statewide emissions are apportioned to counties using a su rrogate. In the case of consumer products, statewide emissions are apportioned to counties using population.May 7, 2007 Appendix F 22 Once ARB has developed a draft methodology, it is submitted to Emission Inventory Technical Advisory Committee (EITAC) for review. EITAC is composed of emission inventory staff from the districts, ARB, and U.S. EPA. Following EITAC review and incorporation of recommended changes, the methodology becomes final and, where appropriate, emissions are reconciled with the point source inventory. Finally, process

rate and emissions transaction format file s are prepared and the CEIDARS database is updated.

The districts also provide updated emissions data to ARB. Process rate and emissions transaction format files provided by the di stricts are used to update the CEIDARS database. When they are provided, the me thodologies developed by districts are reviewed by ARB.

CEFS Forecasting Algorithm (U sed for Stationary, Area-wide, Aircraft, and Ships)

The general forecasting equation for stationar y sources is shown below. The CEFS processor calculates seasonal projecti ons for planning and month/day specific projections for photochemical modeling inputs. CEFS employs a region and emission category selection hierarchy when selecting and applying growth and control factors. Consider, for example, a rule which applies to the entire universe of a particular process type (identified by source classification code (SCC )). If that rule is more stringent for a particular industry (identified by SIC), then a control profile specific to the SCC/SIC combination can be assigned. CEFS will cycle through the control data records applying the highest level of the selection hierar chy to that category (i.e. the growth and control data can be “layered” to target the sour ce categories exactly as the rule calls for without double-counting (or overla ps). The same type of logic is used for the growth

data.

To better characterize emissions affected by seasons, seasonal adjustment factors (or “temporal factors”) are used to apporti on emissions into the periods under consideration. The temporal algorithm used for calculating seasonal emission inventories was rewritten to better approximat e the seasonal variation of emissions. In the prior algorithm used in the 1994 SIP, emission estimates for point sources represented an “average annual oper ating day”. The assessm ent of this algorithm showed that it did not accurately estima te seasonal emissions because the algorithm was driven by the number of operating days a point source process operates. For processes that operated intermittently, this resulted in exaggerated seasonal emission estimates because the algorithm assumed t hat all intermittent processes operated simultaneously. For area sources , the prior algorithm estima ted emissions based on an “average seasonal op erating day”.

ROG, VOC, PM 10 and PM 2.5 Fractions

The reactive portion of the total organic gas (TOG) emissions (expressed as ROG) are calculated by applying reactive fractions wh ich are maintained in CEIDARS. Districts may supply fractions at the fa cility/device/process level for point source processes. If these data are not provided at this level, default fractions maintained by ARB at the SCC level are invoked. In like manner, t he portion of PM falling within the 10 micron and 2.5 micron size ranges (i.e. PM 10 and PM 2.5 respectively) are estimated from district-supplied fractions or by applying size fractions maintained by ARB in CEIDARS. As with the temporal factor, an emissi on-weighted fraction is developed for each SCC/SIC pair.

Growth Factors (Stationary and Area Sources Only)

Growth factors are derived from county-specif ic economic activity profiles, population forecasts, and other socio/demographic acti vity. Growth profiles are typically associated with the type of industry and secondar ily to the type of emission process. For point sources, economic output profiles by industrial sector are typically linked to the

emission sources via SIC. For area sour ces, other growth parameters such as population, dwelling units, fuel usage etc. may be used. The growth factor is the ratio of the growth level in the future year to the growth level in the base year. These growth levels are also region and source category dependent.

Data Acquisition

Growth factor data for use in CEFS are acqui red from the district s, and where no data are available, growth activity projecti ons are constructed from ARB contracts 10 with experts in the economic and demographic gr owth. ARB may also develop growth

estimates in consultation with stakeholders. For example, ARB led an effort to revise growth assumptions in agricultural categorie s, under guidance of the State’s Agricultural Advisory Committee. Geographically speaki ng, much of the State relies on these constructed growth projections while other high emission regions, such as the South Coast and Bay Area, submit their own gr owth estimates based on data provided byMay 7, 2007 Appendix F 24 local councils of government (COGs). The varied sources of growth data are assembled into a comprehensive statewide growth data set that can be used for statewide emission projections.

Control Factors

Control factors are derived from “adopted” ARB regulations, district rules, and “proposed” measures which impose emission reductions or a technological change on a particular emission process. Control fact ors comprise three components: Control Efficiency, Rule Effectiveness, and Rule Penetr ation. Control factors are closely linked to the type of emission proce ss and secondarily to the type of industry. Control levels are assigned to emission categories which are targeted by the rules via emission inventory codes (SCC/SIC, EIC etc.) used in CEID ARS. The control factor is the ratio of

the control level in the future year to the control level in the base year. These control levels are also region, control measure, source category, and pollutant dependent.

Data Acquisition

The baseline emission projections require a fu ll complement of control factor data that account for the “adopted” rules that are on the books by a predetermined cutoff date. A major component of the CEFS program is it s ability to link rules to targeted emission categories and quantify the emission reduc tions associated with the rules. Implementation of CEFS requires districts to submit local c ontrol rule profiles (for all rules leading to emission reductions) that link the rules to the appropriate emission categories. The profiles must describe the behavior of the rule (i.e. whether the rule is phased in a linear fashion or abr upt implementation in the form of a step function). The rule profiles must be desig ned to be pollutant specif ic and must carry enough data points to adequately characterize the rule ov er the implementation period. The CEFS program interpolates the profile for intermedi ate years in either a step or linear mode depending on what the district has flagged fo r the rule. The construction of a comprehensive control rule data set for a lar ge district is a sizeable undertaking. Some districts develop the control profiles in house, while others have opted to contract the work out. In either case, ARB staff work clos ely with the district st aff and/or contractors to educate staff on the proper construction of t he control profiles. In gearing up for the 8-Hour Ozone SIP, in Fall 2004, ARB conduc ted a special forecasting workshop to provide guidance to districts on all aspects of the emission forecasting program including presentations on forecasting logic and input data requir ements. In most cases, districts responded by submitting rule-s pecific control profiles for their adopted rules as required.

ARB also develops control profiles for state rules and International Maritime Organizations (IMOs) such as for consumer products, pesticides, architectural coatings, and ships. For state rules, ARB deploys inte rdivisional teams to develop, refine, and finalize the control profiles to be used in SIP projections. Similar data requirements exist for the development of these control profiles as descr ibed above for district rules.May 7, 2007 Appendix F 25 Mobile Sources

Mobile sources include a ll non-stationary sources of air pollution such as cars , trucks, motorcycles, buses, airplanes, and locomotives. In general, emissions are calculated as the product of the number of sources population/volume), activi ty and emission factor.

E = Pop * A * EF

where, E = pollutant specific emissions [mass emitted per unit time] Pop = population of on-road mobile sources [-] A = activity (travel data) [e.g. miles traveled per day, or hours operational] EF = source specific emission factor [mass per unit activity]

In California, most mobile source invent ories are estimated by two mathematical modeling tools: EMFAC for on-road source s and OFFROAD for off-road sources. Because many different types of data are nece ssary to develop an inventory, ARB must rely on other organizations to provide that dat a. The inventory has involved the efforts

of the California Air Pollution Control Offi cers Association, CalTrans, the Southern California Council of Governments (SCAG), and the DMV. CalTrans provides SCAG with information regarding highway projects so that they can estimate and project vehicle miles traveled (VMT) from their Travel Demand Model (TDM). This activity data are then coupled with the emission factor s generated from ARB’s Emission Factor Model (EMFAC2007) and popula tion data provided by the DMV to calculate the emission inventory. Finally , all statewide emission inve ntories are assembled and maintained by ARB in the CEIDARS and CEFS databases.

On-Road Emission Inventory

EMFAC contains several different modules t hat account for different portions of the onroad inventory calculation process. EMFA C covers on-road mobile sources including gas and diesel cars, trucks, buses, and motor cycles. The subsequent sections illustrate the methods by which the on-road emission in ventory is developed. For more detailed information please refer to the ARB website at http://www.arb.ca .gov/msei/onroad/onroad.htm . A guide to online documentation is also provided at the end of this section.

Source Categories

On-road mobile sources are categorized into thirteen vehicle classes, two fuel types (gas and diesel), and three technology categories (catalyst, noncatalyst and diesel) as

indicated in the table below.May 7, 2007 Appendix F 26 EMFAC Vehicle Categories

Population and Activity

In general, population data are obtained from vehicle registration data compiled by DMV and classified according to fuel, class, technology group, age (model year) and geographic area. Further calculations r equire data on population growth rates by calendar year, vehicle class, fuel ty pe and geographic area. These estimates are coupled with activity data and emission factors, as indicated previously, to estimate total

emissions.

On-road activity refers most commonly to vehicle miles traveled, speed, and number of trips for each vehicle type and model year.

Vehicle Miles Traveled Vehicle miles traveled (VMT) are the number of miles traveled by a given vehicle in a specified time period and is estimated from the inspection and maintenance program (I &M) where the model year and odometer reading is taken. The COG’s provide VMT as estimated by their transportation

demand models. EMFAC then matches VMT estimated in the model to those values provided by

the COGs.May 7, 2007 Appendix F 27 This analysis is completed for each county and helps to elucidate regional differences in

travel. VMT is calculated based on the v ehicle population and accrual rates by age, vehicle class, fuel type, by geographic and inspection and maintenance option. The model also contains hourly dist ributions of VMT by class.

Vehicle Starts or Trips Vehicle starts are obtained for gasoline-power ed vehicles except heavy-duty trucks and included as an input to the inventory. Star ts are used to calculate trip emissions and calculated as the product of a per-vehicle star t rate (starts per v ehicle per day) and the fleet population. The estimates of trips per day are based on travel surveys and vehicle instrumented data for passenger cars, and light and medium duty trucks.

Ambient Temperatures Because motor vehicle emissions are dependent on temperature and humidity profiles, historical meteorological data are compiled. The emission inventory process includes data on averaged monthly, summer and winter epi sodic diurnal temperatures for each geographic area as well as averaged mont hly relative humidity for each geographic area. The following table indi cates the primary data sources for activity and population:

Emission Factors

Emission factor used in EMFAC are based on emission tests with dynamometers coupled with certification data yield base em ission rates (BERs) that are adjusted with correction factors, and vehicle inspection and maintenance (I&M) programs (e.g. smog check scenarios). Correction factors are applied for non-standard operating conditions such as what mode the vehicle is in (e .g. hot/cold/start/running), trip speed, environmental conditions, and inspection an d maintenance progr ams within that geographic area. These correction factors include, but are not limited to, speed correction factors, temperatur e correction factors, fuel co rrection factors and driving cycle correction factors. Emission factors are provided for different temperatures, operating speeds, emission modes, model types, model years, technology types, fuel, and relative humidity. These em ission factors can be expressed as grams per vehicle, grams per mile, grams/hour and grams per start. Activity data are matched to the corresponding

emission factor to estima te total emissions.

EMFAC includes tailpipe exhaust and evaporative emissions as part of the on-road inventory. Tailpipe exhaust emissions include running, idle and start exhausts. Running exhaust represents emissions released from the tailpipe under hot st abilized conditions, while idle and start exhaust, the other ta ilpipe emissions, include any emissions associated with idling and starti ng the vehicle. Evaporative emissions consist of hotMay 7, 2007 Appendix F 28 soaks, diurnals, resting losses and running losses all of which are generated by the evaporation of fuel from an engine. The inv entory accounts for particulate matter (PM)

associated with tire and break wear.

Other Mobile Emission Inventory

Off-road mobile sources include off-road vehi cles such as boats, outdoor recreational vehicles (ORV’s), industrial and constr uction equipment, farm equipment, lawn and garden equipment, ships, aircraft, and trains. OFFROAD is used to estimate emissions for most of these categories. Other sources such as ocean going vessels and

commercial harbor craft are based on calculati ons in modules external to OFFROAD.

Off-road emissions are calculated much in the same way as on-road emissions – the product of emission factor, activity, and popul ation. The model also incorporates elements such as technology types, population, activity, horsepower , load factors, and

control factors. For more detailed info rmation please refer to the ARB website at http://www.arb.ca.gov/mse i/offroad/off-road.htm . In addition, a guide to online documentation is provided at t he end of this section.

Source Categories

Off-road sources are divided up in to eight major categories: aircraft, trains, ships and commercial boats, recreational boats, off-road recreational vehicles, off-road equipment, farm equipment, and fuel storage and handling. The categories are then subdivided by fuel type, engine type, horsepower group and preempted or non-preempted status to better characterize emissions, adopted and proposed control strategies, and use. Outlined below are a few categorical descriptions.May 7, 2007 Appendix F 29 Commercial Marine Vessels

Commercial marine vessels include ocean-go ing ships and harbor craft, but exclude recreational vessels. Ocean-going ships incl ude international trade vessels such as container ships, bulk carriers, general ca rgo ships, tankers, and auto carriers. Passenger cruise ships, and some military and Coast Guard vessels, are also included in this category.

The diesel engines powering the majority of oceangoing ships are re ferred to by U.S. EPA as “Category 3” engines, m eaning they have a displacem ent greater than 30 liters per cylinder. These engines ar e available in configurations with 4 to 14 cylinders, and power outputs ranging from roughly 5 to 100 megawatts.

Ocean-going ships generally run boilers and dies el generators in addition to propulsion engines, particularly while “hotelling” in por t. Diesel generators provide electrical power for lights and equipment, and boilers provide st eam for hot water and fuel heating.

Most ocean-going ships run their main propul sion engines (and many newer ships also run their auxiliary engines) on intermediate fuel oil (IFO 180 or IFO 380). This fuel is

also referred to as “bunker f uel,” and requires heating to redu ce its viscosity to a point where it can be properly atomiz ed and combusted. Bunker fuel typically contains much higher levels of sulfur, nitrogen, ash, and other compounds which increase exhaust emissions. Diesel-powered gas turbine eng ines and auxiliary engines on many oceangoing ships use lighter “distillate” diesel fuel (also referred to as marine gas oil), which is

much lower in sulfur and other contaminants.

Harbor craft (or the “captive fleet”) incl ude tugboats, commercial fishing vessels, commercial passenger fishing vessels, work boat s, crew boats, ferries, and some Coast Guard and military vessels. These vessels generally stay within California coastal

waters and often leave and return to the sa me port. Most harbor craft use dieselpowered propulsion and auxiliary engines that generally run on distillate diesel fuel.

Locomotives and Rail-yards

Railroads operate national locomotive fleets that travel between states daily, currently moving more than 40 percent of the total inte rcity revenue ton-miles of freight in the

United States.

Compression-Ignition (diesel) Engines

Off-road compression-ignition (CI) engines are diesel engines primarily used in farm, construction, and industrial equi pment. Examples include tr actors, excavators, dozers, scrapers, portable generat ors, transport refri geration units (TRUs), irrigation pumps, welders, compressors, scrubbers, and sweeper s. Locomotives, commercial marine vessels, marine engines over 37 kilowatts (k W), or recreational vehicles are excluded from this category.May 7, 2007 Appendix F 30 Large Spark-Ignition Engines

The large spark-ignition engine (LSI) cat egory consists of off-road spark-ignition engines greater than 25 hors epower and typically fueled by gasoline or liquefied petroleum gas (LPG). A sm all number are fueled by comp ressed natural gas (CNG), and some have dual fuel capability. LSI engi nes are most commonly found in forklifts, specialty vehicles, portabl e generators, pumps, compre ssors, farm equipment, and construction equipment. This category ex cludes marine propulsion engines, engines used in equipment that operat e on rails, recreational vehi cles, snowmobiles, and gas

turbines.

Recreational Vehicles

This category consists of off-road motorcycl es and all terrain vehicles (ATVs), both of which are designed for operation over rough terrain. U.S. EPA standards for exhaust and evaporative for off-road motorcycles and ATVs were established in 2006. Although

the federal exhaust standards ar e not as stringent as Califo rnia’s, California will benefit from the evaporative st andards which control fuel tank and fuel line permeability.

In 1994, ARB approved off-highway recreational vehicle regulations (including off-road motorcycles). These regulations estab lished exhaust emission standards and test procedures that included off-road motorcycles and ATVs. The regulations also provided specific coding requirements of the vehicle i dentification number to distinguish an emission-compliant vehicle. In 1998, t he regulations were amended to link vehicle registration and usage to compliance with Ca lifornia’s exhaust emission standards. Those in compliance are eligible for off-hi ghway vehicle (OHV) green sticker registration that allows year-round operation in designated off-road areas. Those not in compliance are eligible for OHV red sticke r registration that allows oper ation only during designated

months when ozone levels are low. These re visions affect engines built in 1997 greater than 90 cc. The same standards also apply to engines built in 1999 of 90 cc or less. Engines built pre-1997 and pre- 1999, respectively, are not subject to this regulation.

Small Off-Road Engine (SORE)

The small off-road engine (SORE or "small engi ne") category consists of off-road sparkignition engines fueled typically by gasolin e, liquid petroleum gas (LPG) or other

alternative fuels and below 25 horsepower. The SORE categor y includes lawn, garden and other maintenance utility equipment. Within this category, engines are typically grouped by engine displacement measured in cubic centimeters (c c). Engines under 65 cc displacement are traditionally associ ated with handheld equipm ent such as weed trimmers, leaf blowers and chain saws. E ngines greater than 65 cc displacement are collectively referred to as non-handhel d small off-road engines. Non-handheld equipment is primarily lawn mowers, but al so includes other equipment such as riding mowers and generator sets.

The sources of evaporative emissions from this category are from gasoline vapors

vented from the carburetor and fuel cap and occur from diurnal (emissions due to daily temperature changes), hot soak (occur afte r shutdown of equipm ent), and running loss (occur during equipment operation) processes. Permeation (liquid gasoline migrating through the walls of plastic fuel tanks) is also another source of emissions.May 7, 2007 Appendix F 31 Activity and Population

As with the on-road inventory, emission fa ctors must be coupl ed with population and activity data to estimate total emissions . The statewide equipment population of offroad mobile sources was collected from a variety of sources including industry and government agencies. Then growth factors based on socioeconomic indicators and scrappage factors were applied to determine future populations. Scrappag e, or attrition, functions describe the relationship between equipment age and the proportion of equipment that has been removed from service. It is expressed as a fraction of the average lifetime of the equipment and is a f unction of the expected life of the engine,

the annual hours of operation, and the average load factor.

Activity includes information such as annual average usage hours, load factor, brake-specific fuel consumption, and starts per year for each equipment type by fuel, engine type, and horsepower

group.

Data Acquisition

The statewide equipment populations were obtained through various industry and government agency sources. Power Systems Re search (PSR) is the source for many of the state population estimates for off -road categories. PS R’s Power Systems Research/Compass International’s 1996 Dat abase contained engine data compiled over the last 7 years, and included engine sales records for every engine installed in North America, as well as imported engine-dr iven products. E ngine data includes horsepower, model number and engine descripti on (number of cylinders, turbocharged versus naturally-aspirated, displacement, etc) . Some of the principal data sources, by category, are listed in the table below:

The Portable Equipment Database is maintai ned by ARB. Data are obtained through a voluntary registration program with the State as an alter nate method of obtaining an operational permit for off-r oad non-propulsion engines. Equipment populations for dredging, oil drilling, lawn and garden, m ilitary tactical support and other portable equipment categories were obtai ned directly from the Portable Equipment Database. In

order to avoid double count ing, the population of generat ors, pumps and compressors found in the drilling, dredging, tactical support and other portable equipment, were

subtracted from the i ndustrial and light-commercial categories.May 7, 2007 Appendix F 32 Category Data Source

MacKay & Company conducted surveys in 1991, 1995, and 1999 to estimate nationwide construction equipmen t population and usage. This work was sponsored by Construction Equipment Magazine. Ma cKay & Company’s 1999 Construction Equipment population analysis was used to obt ain populations for those construction equipment contained in the analysis. Since dat a in MacKay’s analysis are nationwide,

staff used a factor of 10 percent in order to estimate Ca lifornia’s statewide population.

U.S. EPA staff estimated that 10 percent of the total nationw ide dollar amount spent on

construction-related activities occurs in Calif ornia. For specific pieces of construction equipment not found in MacKay’s analysis, 10 per cent of PSR’s nationwide data were

used.

Finally, all statewide emissi on inventories are assembled and maintained by ARB in

CEIDARS and CEFS databases.May 7, 2007 Appendix F 33 Emission Factors

ARB estimates all off-road mobile emissi ons with OFFROAD. OFFROAD integrates emission factors by model year for hydroc arbons (HC), carbon monoxide (CO), carbon dioxide (CO 2 ), oxides of nitrogen (NO
x ), particulate matter (PM) , and oxides of sulfur (SO
x ). Hydrocarbon emissions are modeled fo r three types of engine processes: exhaust, evaporative and start emissions.

The emission factors for each engine are a function of new engine emissions expressed in grams per brake horsepower hour and

deterioration rates. Deterioration is due primarily to tampering and mal-maintenance and wear on engine parts with use, and

occurs at different ra tes for each pollutant. The OFFROAD methodology for estimating

deterioration is based on the zero-hour emission rate (g/bhp-hr), the deterioration rate (increase in emissions per unit of activity, g/bhp-hr 2 ), and the number of hoursaccumulated on the equipment. Equipmentspecific emission factors are obtained by adjusting the appropriate engine emission rate by how the equipment is used (duty cycle). Finally, control factors can be applied to emissions or population to account for regulatory control scenarios.

Development of effective ozone and PM2.5 cont rol strategies in California requires accurate emission inventories of their precur sor emissions, including biogenic volatile organic compounds (BVOCs) such as is oprene and monoterpenes. Due to the heterogeneity of vegetation land cover, species composition and leaf mass distribution in California, quantifying BVOC emissions in this domain requires an emission inventory model with region-specific input databases and a high degree of spatial and temporal resolution. In response to this need, AR B developed a GIS-based model for estimating BVOC emissions, called BEIGIS, which uses Ca lifornia-specific in put databases with a minimum spatial resolution of 1 km 2 and an hourly temporal resolution.

The BEIGIS isoprene emission algorithm 11 is of the form I = IS × CL × CT , where I is the isoprene emission rate (grams isopr ene per gram dry leaf mass per hour) at temperature T and photosynthetically active r adiation flux PAR. IS is a reference emission factor (grams isoprene per gram dry leaf mass per hour) at a standard temperature of 30 °C and PAR flux of 1000 μmol m -2 s -1 . CL and CT are environmental adjustment functions for PAR and temperat ure, respectively. The monoterpene emission algorithm adjusts a reference mono terpene emission factor by a temperature

function 11 . Methylbutenol (MBO) emissions are modeled with an algorithm 12 similar to that for isoprene. Dry leaf ma ss/ leaf area ratios, and reference emission factors for isoprene, monoterpenes and MBO, are plant spec ies-specific and assembled from the

scientific literature. Model ed BVOC emissions for a gi ven spatial domain therefore represent the contribution by various pl ant species (through their leaf mass and emission rates) to t he total BVOC emissions.

The main inputs to BEIGIS are land use la nd cover (LULC) GIS databases, gridded leaf area index (LAI) derived fr om AVHRR satellite data 13 , leaf area/dry leaf mass factors, reference emission factors, and gridded hourly ambient temperatur e and sunlight data (generated by the CALMET and/ or MM5 models). For urban areas, LULC databases were developed from regional pla nning agency data and botanical surveys 14 . Natural areas are represented using GAP, a st atewide LULC database developed by the University of California-Sant a Barbara for the U.S.G.S. Bi ological Resources Division and the California Department of Fish and Game 15 . Agricultural areas are represented using crop GIS databases developed by the Ca lifornia Department of Water Resources (http://www.landwateruse.water.ca.gov ). Ground surveys have been funded by ARB to validate vegetation land cover and LAI input databases used in BEIGIS 16 . Model validation using micrometeorological fl ux measurements is on-going. BEIGIS assimilates spatial and temporal inputs and executes BVOC emission algorithms within a GIS. Outputs from BEIGIS are gridded 1 km 2 hourly emissions of isoprene, monoterpenes and MBO, aggregated to 16 km 2 or 25 km 2 resolution, depending on photochemical modeling requirem ents. A fourth BVOC categor y called “other” biogenic VOC (OVOC) is comprised of compounds such as acetone, methanol, and other oxygenated BVOCs. OVOC is not modeled directly. Gr idded hourly OVOC emissions are estimated as an added fraction, scaled to 30 percent of the sum of isoprene, monoterpene, and MBO within each grid cell. A speciation profile is applied to theMay 7, 2007 Appendix F 35 OVOC fraction based on OVOCs measur ed at Blodgett Experimental Forest 17 . The BEIGIS model was first applied in the Southern California Ozone Study 18 (SCOS97).

Emissions Inventory Systems Data (CEIDARS, CEFS)

ARB redesigned its base year emission inve ntory system (known as the California Emissions Inventory Development and R eporting System (CEIDARS)) in 1995 and emission forecasting system (known as the California Emission Forecasting System (CEFS)). Technical papers describi ng these systems are available on request.May 7, 2007 Appendix F 36

### Appendix G

Legal Authority and Other Requirements(This page intentionally left blank.)May 7, 2007 Appendix G 1 Overview of California’s Legal Authority

Legal authority to regulate sources of air pollution in California is found in both

federal and state law. At the federal le vel, the Clean Air Act (“the Act” or “CAA”) calls for a two or three partner endeavor involving federal, state and, where permitted by state law, local authorities. The Act directs the U.S. Environmental Protection Agency (U.S. EPA) to undertake a national effort to improve air quality. To carry out this directive, U.S. EPA is directed to establish national ambient air quality standards to protec t the public health and welfare (CAA §109).

The primary tool to be used in the effort to attain national standa rds is a SIP to be developed by each state that has one or more nonattainment areas. The SIP must provide for implementation, maintenance, and enfo rcement of the national standards (CAA § 110(a)(1)). CAA § 110(a)(2)(A) broadly authorizes and directs

states to include in their SIPs:

"...enforceable emission limitati ons and other control measures, means, or techniques (including ec onomic incentives such as fees, marketable permits, and auctions of emissions rights ), as well as

schedules and timetables for compliance, as may be necessary or appropriate to meet the applic able requirements of this Act."

While the Act requires states to develop SIPs, and clearl y intends that they bear primary responsibility for atta ining the national standards (C AA §101(a)(3 )), it also provides U.S. EPA with two significant role s in this process. As a partner in the effort to attain and maintain the standards, U.S. EPA is authorized and directed to adopt measures to control emissions from various sources, such as consumer products, motor vehicles, nonroad engines and vehicles, and aircraft (CAA §§183(e)(3), 202, 213 and 231). Additionally, U.S. EPA has ultimate authority and responsibility to in tervene with direct federal action if th e SIP is inadequate, incomplete or not properly implemented by the state (CAA §§ 110(c)(1) and 113).

Similarly, Cali fornia law generall y divides responsibili ty for meeting the requirements of the Clean Air Act (as we ll as separate, co mprehensive state requirements related to air quality) between ARB and local air pollu tion control or air quality management dist ricts (districts). Ho wever, other state or local agencies also have the authority under stat e law to regulate certain pol lutant-emitting sources or activities. For example, the State's mo tor vehicle inspecti on and maintenance program is primarily the responsibility of the Bureau of Automotive Repair in the Department of Consumer Affairs, and th e Department of Pesticide Regulation has primary authority to regulate the use of pest icides. Legal authorit y for state, district, and local efforts to improve air quality is contained primarily in Division 25.5 and

Division 26 of the Californ ia Health and Safe ty Code, although au thority for some programs is located elsewh ere in the State codes. 1

1 All section references in this discussion are to the Health and Safety Code unless otherwise specified.May 7, 2007 Appendix G 2 Pursuant to these codes, ARB is charged with co ordinating, regional and local

efforts to attain and maintain both state and national ambien t air quality standards. The direct statutory link between ARB and the mandates of the CAA is found in §39602 of the Health and Sa fety Code, which states:

"The state board is designate d the air pollution control agency for all purposes set fo rth in federal law. The state board is designated as the state agency responsible for the preparati on of the state implementati on plan requ ired by the Clean Air Act (42 U.S.C., Sec. 7401, et seq.) and, to this end, shall

coordinate the activities of all districts necessary to comply with that

act. Notwithstanding any other provis ion of this division, the state implementation plan shall only incl ude those provisions necessary to meet the requirements of the Clean Air Act."

In directing the California approach to improving air quality, State law divides

control activities into vehicular and no nvehicular sectors (§§39002 and 40000).

The control of vehicular so urces is the responsibility of ARB, while primary responsibility for nonvehicula r controls falls to the loca l air districts (§§ 39002, 40000-40002, 40702, 4 0717; see also §§ 40400- 40540 for provisions specific to the South Coast Air Quality Management District). T hese authorities have been used by the local district s to adopt and enforce numer ous rules to control air pollution. In a ddition, ARB has comprehen sive oversight authorit y over the districts

to undertake nonvehicular source control acti vities if any districts fails to perform satisfactorily (§§39002, 41500, 41502, 41503, 41 504, 41505 and 41652).

The Clean Air Act requires that SIP provisions be legally enforce able. Under State law, a tiered system of authority for enfo rcement exists which pa rallels the authority to develop and implemen t the SIP. ARB has authority to enforc e vehicular controls. (See, e.g., §§41510, 41511 and 41513, 43012, 43016 and 43017, 4 3100, 43105, 43106, 43204-43212 and Vehicle Code §§27156, 38390 and 38391.) Primary responsibility for nonvehicular enforcement is vested in the local air districts. (See, e.g., §§41510, 41511 an d 41513, and 42300 et seq.) Ho wever, if ARB finds that a

district is not taki ng reasonable action to enforce applicable air pollution control statutes, rules and regulat ions, ARB may, after a publ ic hearing, assume the district's enforcement power s and enforce these laws (§41505). U.S. EPA has similar authority to assume enforcement juri sdiction if a state fails to enforce SIP provisions (CAA §113).

Within the framework of state and local shared responsibility for air pollution control, with ultimate air district acc ountability to ARB, ARB has the necessary statutory authority to assu re compliance with the requirements of the Clean Air Act relating to the attainment of na tional standards and the rate-of-progress

demonstrations.May 7, 2007 Appendix G 3 Legal Authority to Adopt St ate and Federal SIP Measures

State components of the 2007 SIP are des igned to reduce emissions from onroad mobile sources (passenger vehicles and trucks), off-road mobile sources (agricultural equipment, construction equipment, and other off-road sources), goods movement sources, and areawi de sources (consumer products and pesticides). The legal authority for implem enting the measures in each of these categories is described below.

Mobile Sources

Mobile source measures are a central comp onent of the 2007 SI P. The measures

include reductions to be realized from ac tions taken or to be taken at both the

federal and state level.

Federal Responsibility for National Mobile Source Measures

If all areas of the St ate are to demonstrat e attainment by the specified deadlines, a critical part of the overall strategy to reduce mobile sour ce emissions in California

must be U.S. EPA's regulation of national sources pursuant to §§2 02(a)(2)(B), 213

and 231 of the Clean Air Ac (CAA). Projected emi ssions from sources under federal jurisdiction are very significant, and these emissi on categories are expected to grow dramatically through 2024 wi thout new strategi es. Under these circumstances, U.S. EPA has an obligation under the CAA to pr omulgate standards for these unregulated or underregulated national sour ces. Such measures should be fully creditabl e in the SIP.

Certainly, U.S. EPA has the authority to adopt standards for national sources in

order to assist states in achieving the national am bient air quality standards (NAAQS). U.S. EPA's author ity derives from a number of provisions of the Clean Air Act which authorize or require the pr omulgation of variou s types of control

measures. The sc ope of U.S. EPA's authority under many of these provisions is broadly defined. For example, CAA §202 directs the Administra tor of the U.S. EPA

to establish emission stan dards for new motor vehicles and CAA §231 directs the

Administrator to establish aircraft emission st andards. Both of th ese sections direct the Administrator to promul gate regulations in order to control emissions:

"which, in his judgment, cause or contribu te to air pollution which may reasonably be anticipate d to endanger pub lic health and welfare ..." (CAA §§202(a) and 231(a)(2)).

CAA §213 provides U.S. EPA with the au thority to adopt emi ssion standards for nonroad engines and vehicles (such as marine vessels, construction equipment, and farm equipment). Unde r §213, the Administrator is required to determine whether ozone pr ecursor or carbon m onoxide emissions from nonroad engines or vehicles (other than locomotives) "cause, or significant ly contribute to , air pollution which may reasonably be anti cipated to end anger public health or welfare" and to regulate the sources that in his judgme nt "cause, or contribute to, such airMay 7, 2007 Appendix G 4 pollution." CAA §213 also directs the Administrator to adopt emission standards for

new locomotives that:

"achieve the greatest degree of emission reduction achievable through the app lication of technology which the Administrator

determines will be availa ble for the locomotive s or engines to which such standards apply, gi ving appropria te consideration to the cost of applying such technolog y within the period of time available to

manufacturers and to noise, energy and safety factors associated with the application of such technology." (CAA §213(a)(5).)

Federal law preempts individual states fr om adopting emission standards for most of these sources (see CAA §§209 and 233). As explai ned in the next section, however, California has co ncurrent authority to regul ate some nonroad engines or vehicles including marine vessels, and Ca lifornia can obtain a waiver of federal preemption to adopt emission standards for other nation al source categories.

If California is to ade quately protect public health, the essential emission reductions necessary from these sources must be fully realized through ti mely promulgation of

all feasible standards for national sources by U.S. EPA under the authorities provided in the Act. Wi thout such federal contro l of preempted and national transportation sources, Cali fornia simply canno t adequately prot ect public health because it is not possible to obtain sufficient emission reductions solely from sources under local and juri sdiction to offset uncont rolled or undercontrolled emissions contributed by national sources subject to federal control.

The very broad language of the Clean Air Act authorizes and directs the Administrator to establish appropriate st andards for national sources in order to effectively address emissions from these sources in California and other states. Such standards are necessary and technolog ically feasible; therefore, U.S. EPA has an obligation to promulgate t hese standards without delay.

General State Authority for Mobile Source Measures

ARB has broad authorit y under State law to regulate m obile sources. Health and Safety Code §§ 43000, 43000. 5, 43013(b) and 43018 provide authority for ARB to adopt emission standards and other regul ations to reduce emissions from new and in-use motor vehicles and other mobile sources. These authorities empower the Board to adopt the mobi le source regulat ions and other co ntrol measures

identified in this SIP. Health and Safety Code §43013(a) provides that:

"The state board may adopt and implement motor vehicle emission standards, in-use performance stan dards, and motor vehicle fuel specifications for the control of ai r [pollutants] and sources of air pollution which the stat e board has found to be necessary, costeffective, and technologica lly feasible to carry ou t the purposes of this division, unless preemp ted by federal law."May 7, 2007 Appendix G 5 In addition, Health and Safe ty Code §430 18 provides:

"The state bo ard shall endeavor to achieve the maximum degree of emission reduction possible from vehicular and other mobile sources in order to accomplish the attainment of the state standards at the earliest practical date."

To carry out these directives, the Board is directed to:

"... adopt and implement emission standards for new motor vehicles [or new motor vehicle engi nes] for the control of emissions therefrom,

which standards the st ate board has found to be necessary and technologically feasible to carry out the purposes of this division. Prior to adopting such standards, the state board shall consider the impact of such standards on the ec onomy of the state, including, but not limited to, their effe ct on motor vehicle fuel efficiency ." (§43101)

The Board is also directed by §43013(b) to regulate ot her categories of mobile

sources:

“The state board shall ... adopt standards and regulations for ... off-road or nonvehicle engine categori es, including, but not limited to, off-highway motorcycles, off-highway vehicles, constr uction equipmen t, farm equipment, utility engines, locomotives, and, to the extent permitted by federal law,

marine vessels.”

ARB is further authorized by State law to adopt Air Toxic Control Measures (ATCMs) to control identified toxic air c ontaminants (TACs). ARB has identified anumber of substances as TACs, including “particulate emissions from dieselfueled engines” (see title 17, Californi a Code of Regulations, sections 93000 and 93001). The autho rity to identify TACs and adopt ATCMs is provided by the Tanner Act (Health and Safety Code §39650 et seq.). Under the Tanner Act, ARB may adopt ATCMs to control TAC emissions from both nonvehicular sources (such as off-road diesel en gines and equipmen t, marine vessels, etc.) and from

vehicular sources such as on-road diesel trucks (s ee §§36658, 39666, and 39667). ATCMs may specify both new and in-use emission stan dards for all of these

sources.

Each of the sections cited above must be read in the context of Health and Safety Code 39600, which prov ides that: "The state board s hall do such ac ts as may be necessary for the proper execution of the powers and duties granted to, and imposed upon, the state board by this division and by any other provision of law."

Pursuant to these authorities ARB ha s adopted the world's most stringent standards for passenge r cars, light-duty trucks and medium-duty vehicles. ARB has also adopted regulations establishing standards for heavy- duty vehicles, offroad vehicles and engines, including sm all off-road engines and equipment (e.g., lawn and garden, small utility engines), off-road recreat ional vehicles (e.g., dirtMay 7, 2007 Appendix G 6 bikes, all-terrain vehicles, golf carts), off-road diesel engine s and equipment (e.g.,

certain farm and constructi on equipment, portab le generato rs), off-road gasoline and LPG engines and equipment (e.g., forklifts, airport ground s upport equipment), and marine pleasure cra ft (e.g., jet skies and recreational boats).

Federal Preempti on and Waivers

The CAA preempts states, including Calif ornia, from adopting requirements for new off-road engines smaller than 175 horsepower used in farm or construction equipment. (CAA §209(e)). However, t he CAA does not preempt California from adopting requirements for new off-r oad engines greater than 175 horsepower used in farm or construction equipment. California may also adopt in-use emission standards for off-road engines. However, California must obtain

authorization from the Admi nistrator of the U.S. EPA (i.e., a waiver) under CAA §209(e) before any new or in-use standar ds for off-road vehicles can be enforced, unless such standards are withi n the scope of a previously granted

authorization.

In-use standards for on-road vehicles and engines (such as diesel trucks) are not covered by CAA §209. California is no t preempted from adopting in-use, on-road

standards and does not need to obta in a waiver for such standards.

State Authority to Regulate Marine Vessels

State law authorizes ARB to regulate marine vessels to the extent such regulation is not preempted by federal law. This authority is provided by Health and Safety Code §§43013 and 43018 and by the Tanner Act, which authorizes the adoption of ATCMs to regulate diesel particulate emissions from marine

vessels.

The CAA places certain constraints on ARB’s legal authority to regulate

emissions from marine vessels in Californ ia Coastal Waters. The key issue is whether ARB measures are engine emissi on standards or in-use operational requirements. The CAA pr eempts California from impl ementing engine emission standards (e.g., new or retrofit engi ne standards or re quirements) unless

California has received authorization from the U.S. EPA to enforce such standards under CAA §209(e)(2). However, the CAA does not preempt states from implementing in-use operational standards, which include but are not limited to restrictions on hours of operation, su lfur limits on fuel, and daily mass emission limits (see Appendix A to 40 CFR Part 89, Subpart A, as discussed at 62 FR 67733, 67735 (December 30, 1997)).

The 2007 SIP includes measures to require the use of cleaner, lo w-sulfur fuel in ship auxiliary and main engines. These r equirements are best characterized as in-use operation requirements that are not preempted under the CAA. However, to the extent that these fuel require ments could be characterized as engine emission standards, California would need to get U.S. EPA authorization under CAA section 209(e). Author ization from U.S. EPA under CAA section 209(e) willMay 7, 2007 Appendix G 7 also be needed for the proposed SIP meas ures on harborcraft that would impose new engine and in-use retrofit/repower standards.

The 2007 SIP also includes a cold-ironing measure for ships. This measure will likely not require U.S. EPA authorization si nce the measure can be drafted as an in-use operational requirement. Similarl y, the vessel speed reduction measure in the SIP would clearly be an in-use operatio nal requirement that does not require

U.S. EPA authorization. Ho wever, to the extent t hese two measures mandate the installation and use of specific equipment on board vessels, those mandates would likely require U.S. EPA authorization under CAA §209(e).

Case law supports California authority to regulate marine vessel emissions while the ships are at the ports and in Ca lifornia Coastal Waters, provided a

reasonable “nexus” is established bet ween the regulation and the state’s legitimate interest in protec ting the health and safety of its citizens or its natural resources (see Gillis v. State of Louisiana, 294 F.3d 755, 761 (5 th Cir. 2002)). Properly drafted to avoid impacting the in ternal affairs of a vessel, California regulations on marine vessels could also be extended to foreign-flagged vessels as well as U.S.-flagged ones (see Spector v. Norwegian Cruise Line, Ltd., 545 U.S. 119, 130-131).

Smog Check Program

California’s vehicle inspection and main tenance program (commonly referred to as the “smog check program”) is admin istered by the Bureau of Automotive Repair, which has the author ity under state law for devel oping and implementing the program (§ 44002). T he overall structure of Calif ornia’s current smog check program was established by legislati on enacted in 1994 in response to the requirements of the federal Clean Air Act and U.S. EPA regulations. The laws governing the implementation and enforcement of the program ar e set forth in Health and Safety Code §44000 et seq.

Fuels

ARB has the authority to regulate the cont ent of motor vehicle fuels. This was recognized by the California Supr eme Court in a 1975 decision, Western Oil & Gas Assn. v. Orange Co unty Air Pollution Control District (1975), 14 Cal. 3d 411, 418- 420, which held that the authority of ARB to adopt and implem ent motor vehicle

emission standards incl udes the authority to set standar ds for motor v ehicle fuels.

ARB’s authority over fuels wa s reaffirmed and clarified in the Californ ia Clean Air Act of 1988, which added §43 018 to the Health and Safe ty Code and substantially amended §43013. These sections provide that ARB has the authority to establish motor vehicle fuel regula tions, and that before adopting and amending such regulations ARB must take certain sp ecified actions and make specified

determinations.May 7, 2007 Appendix G 8 Consumer Products

ARB has broad author ity under California law to regulate consumer products. Specifically, Health and Safety Code §41712(b) provides that:

"The state board shall adopt re gulations to achieve the maximum

feasible reduction in volatile organic compounds [V OC] emitted by consumer products, if the state board determin es that ade quate data exists to establish both of the following: (1) The regulations are necessary to atta in state and federal ambient air quality standards. (2) The regulations are commercially and technologically feasible and necessary.” (See also §39600.)

Pursuant to this authority ARB has already ado pted standards for numerous categories of consumer products and has achieved significant emission reductions from these products. ARB will continue to develop and adopt measures that limit the VOC emissions from consumer products.

Vapor Recovery

Health and Safety Code §41954 re quires ARB to adop t procedures and performance standards for controlling gasoline vapo r emissions from gasoline marketing operations, includi ng transfer and storage o perations, to achieve and maintain ambient air qualit y standards. This section also authorizes ARB, in cooperation with districts, to certify vapor recovery systems that meet the performance standards . Health and Safe ty Code §39607(d) re quires ARB to adopt test procedures to determine compliance with ARB and districts’ non-vehicular standards. State law (§41954) further requires districts to use ARB test procedures for determining compliance with perf ormance standards and specifications established by ARB.

To comply with these provisions of stat e law, ARB has adopt ed the gasoline vapor recovery certification and test procedur es found in 17 Ca lifornia Code of Regulations §§94010 to 94015 and 94101 to 94165. These regu lations reference procedures for certifying vapor recovery systems and test procedures for verifying compliance with performance standards and specifications.

Pesticides

DPR has broad author ity under state law to control the use of pesticides for the purposes of protecting human health and the environment, including improving air quality. This authority is set forth in Divisions 6 and 7 of the California Food and Agricultural Code (FAC); (FAC §§14082, 14102, also §§12781, 12824-12828, 12976-12977, 12991-1 2995, 12996-12999, 13101 and 13102 ). Following are more specific descriptions of DPR’s authority in particular areas.May 7, 2007 Appendix G 9 DPR has the power to adopt r egulations to carry out t he provisions of the FAC

that it is authorized to administer or enforce (FAC §§11456, 11502.5, 12781, 12976, 12981). No pesticide may be manufactu red, sold or offered for sale in California unless it has been registered by the DPR (§12811). DPR may place appropriate restrictions on a pesticide’s use, including limitations on the quantity, area, and manner of appl ication (§12824).

Use of pesticides classified as “restricted materials” often re quires a permit (see §§14006.5; title 3, California Code of R egulations (CCR), §6412) . All agricultural and commercial structural use fumigants are re stricted materials. Permits to use restricted materials are issued by t he appropriate County Agricultural Commissioner, or by DPR in counties that have no County Agricultural

Commissioner. DPR can and does recomm end permit conditions to be included in restricted material pe rmits. DPR can also enact us e restrictions or permit conditions by regulation (FAC §14007( a)). DPR must adopt regulations governing the use of any restricted mate rial that the Director determines is injurious to the environment (FAC §14005). It is unlawful to apply any restricted material for which regulations have been adopted except as provided in such regulations (FAC §4011).

All agricultural and commercial structural us e of pesticides must be reported (title 3, CCR §6624 and FAC §12979). Among other information, the Pesticide Use Reports must identify the dat e of application; location of property treated; total acres or units treated; and the pestici de and amount used (tit le 3, CCR §6624).

New Technology Measures for ARB’s Long-Term Strategy

Like the 1994 and 1999 SIPs for the Sout h Coast Air Basin, this SIP contains a special class of new technology measures necessary to contribute to attainment in

the South Coast and San Jo aquin Valley. CAA §182 se ts out requirements for marginal, moderate, serious, severe an d extreme ozone nona ttainment areas, with the requirements for each le vel building on the preceding requirements. The South Coast and San Joaquin Valley have or inte nd to request to “bump-up” to an

extreme classification in or der to show attainment of the federal 8-hour ozone standard by 2024. As extr eme areas, th e South Coast and San Joaqui n Valley will be required to meet the mo st strenuous requirements a pplicable to areas with lesser ozone problems, plus all of the requirements of CA A §182(e)(1) th rough (3). The following discussion applies to any Cali fornia nona ttainment area classified as

extreme.

To address attainment planning for extreme ozone nonattainment areas, Congress enacted CAA §182(e)(5) as par t of the 1990 CAA amendments. Specifically, CAA §182(e)(5) provides:

"The Administrator may, in acco rdance with section 110, approve provisions of an implementation plan for an Extreme Area which anticipate development of new contro l techniques or improvement of existing control technol ogies, and an attainment demonstration basedMay 7, 2007 Appendix G 10 on such provisions, if the State demonstrates to the satisfaction of the

Administrator that-- (A) such provisions are not necessary to achieve the

incremental emission reductions require d during the first 10 years

after the date of the enactment of the Clean Air Ac t Amendments of 1990; and (B) the State has submitted enforceable commitments to develop and adopt contin gency measures to be implemented as set forth herein if the anticipated technologies do not achieve planned

reductions. Such contingency measures shall be submitted to the Administrator no later than 3 years befo re proposed implementation of the plan provisions and approved or disapp roved by the Administra tor in acco rdance with

section 110. T he contingency meas ures shall be adequate to produce

emission reductions suffi cient, in conjun ction with other approved plan provisions, to achieve the periodic emission reductions required by subsection (b)(1) and (c)(2 ) and attainment by the applicable dates. If the

Administrator determines that an Extr eme Area has failed to achieve an emission reduction requireme nt set forth in subsection (b)(1) or (c)(2), and

that failure is due in whole or part to an inability to fully implement provisions approved pursuant to this subsection, the Administ rator shall require the State to implement the co ntingency measures to th e extent necessary to assure compliance with subs ections (b)(1) and (c)(2)."

U.S. EPA approved the new te chnology measures set fo rth in the 1994 and 1999 Ozone SIPS (60 FR 43379, 4381 (August 21, 19 95); 65 FR 6091, 6093 (February 8, 2000), and fu rther explained its interp retation of §182(e)(5):

“The 1990 Amendments to the Act added section 182(e)(5), which applies exclusively to “Extreme” oz one areas. This provision authorizes the State to use conceptual, as yet unadopted measures fo r its ozone attainment

demonstration and rate-of- progress after the year 2000, if these measures anticipate new or improved technology or control tec hniques and are not needed to meet the progre ss requirements of the fi rst 10 years . . . These measures necessarily are pr eliminary, and as such lack both regulations and technical support or even decisions regarding specific directions and approaches. Complete SIP rule elem ents are dependent up on future years of research projects, analyses of te chnologies and associated commercial feasibility, public wor kshops, and public decision making.” (60 FR 43381)

The 2007 SIP for the South Coast and San Joaquin Valley will rely on §182(e)(5) measures for a significant quantity of em ission reductions. This reliance was intended by the Act, and long-term measures that rely on new or evolving technology (including measures requiring complex analyses and decision-making and coordination among numerous governmen t agencies) fall wi thin the coverage of §182(e)(5) and are approvable as SIP re visions although not yet fully developed or adopted.May 7, 2007 Appendix G 11 Use of Secured Incentive Funding

The emission reductions from adopted SIP measures include reductions achieved through incentive programs (such as the Carl Moyer program) that help finance the clean-up of the in-use or l egacy fleet of heavy-duty diesel trucks, buses, and other diesel equipment. Calif ornia is currently investing up to $140 million per year through the Carl Mo yer Program. In the adopted measure emission reduction calculations, ARB incl uded the benefit of emission reductions that will occur in future years from funds that have been directed to ARB and through legislation.

ARB is able to include the benefit of these incentive programs because the funds have been secured for ARB through state legi slation. The Carl Moyer Memorial Air Quality Standards program was establis hed in 1988 and in its first six years, the program provided over $140 million in funding to clean up more than 6,300 heavy-duty engines. State legislat ion (AB 923, 2004 and SB 1107, 2004) provided increased and cont inued funding for the program and other incentive programs – up to $141 million annually thro ugh 2015. The sources of this new funding secured in this legi slation are listed below.

1. Increased and expanded Smog Check pr ogram fee revenues directed to the program provide approximately $61 m illion per year. It is emission

reductions from these revenues t hat have been included in the adopted

measures in this SIP.

2. An increase in the fee assessed for new tire purchases from $1 to $1.75 provides approximately $25 million per year through 2015. The resulting

revenues are directed to the air districts.

3. A $2 increase in the amount of air district-imposed motor vehicle registration fees will provide up to $55 m illion per year to local air districts for clean air incentive programs.

Reasonably Available Contro l Measures (RACM) Discussion

U.S. EPA’s guidance requires each nona ttainment area to submit a demonstration that it has adopted a ll RACM necessary to demonstrate attainment as expeditiously as possi ble. However, U.S. EPA has already

determined that the California (i.e., ARB) control programs for mobile sources

and fuels constitute BACM. 2 Moreover, whereas U.S. EPA deems its federal mobile source program to establish bes t available control measures for the nation, the California program generally goes beyond federal mobile source requirements (where not otherwise prescri bed by federal law). Therefore, ARB

believes that the State mobile sour ce program exceeds federal RACM requirements.

2 See page 5419 of the F ebruary 4, 2004 proposed rulemaking for the San Joaquin Valley PM10 plan, and page 30035 of the May 26, 2004 final rule.May 7, 2007 Appendix G 12 Analyses of measures and adoption commitm ents for sources under air district responsibility subject to RACM and Reas onable Available Control Technology (RACT) requirements are included in the local air district plans.

Conformity Budgets

Section 176(c) of the CAA requires that any action by the Federal government be consistent with, or "conform" to the purpose and intent of the SIP. This section of the Clean Air Act also requires that trans portation planning agencies in areas that do not meet federal air qua lity standards demonstrate t hat their long range plans, funding programs and projects are consis tent with and conform to the SIP before any part of the federal gov ernment grants approval, f unding, or takes any other action on those plans, pr ograms or projects.

In turn, the local air quality attainment plans are required by the Clean Air Act to set out emissions budgets for transporta tion agencies to use when demonstrating conformity to the SIP. These emissi on budgets are linked to the attainment demonstration, and represent an upper bound, or ceiling that cannot be

exceeded without undermini ng the SIP in its efforts to attain the federal air quality standards. Because the development of an area's emission budget takes place at the local level, each loca l plan will contain that area's transportation conformity emissions budgets and supporting mate rial concerning the basis and development of those budgets.
