ARB Proposes to Approve Valley Particulate Matter Plan

Hearing set for May 22 in Fresno

SACRAMENTO - The Air Resources Board released a staff report today that recommends approval of a particulate matter pollution control plan for the San Joaquin Valley that would meet federal health standards on time.

The Board will vote on the staff recommendation -- posted today at http://www.blogger.com/www.arb.ca.gov/planning/sip/sjvpm2.5.htm -- at a hearing in Fresno on May 22. The San Joaquin Valley Air Pollution Control District approved the fine particulate matter state implementation plan April 30.

Local measures such as a strengthened residential wood smoke rule and one of the state's toughest regulations on boilers and glass furnaces will combine with ARB's recently passed off-road construction rule and the upcoming proposed truck regulation to allow the Valley to meet federal fine particulate matter standards by 2014. Parts of the Valley already comply with the particulate matter standard, with southern regions suffering from the worst air quality.

"The combined efforts of ARB and the local air district are lowering soot levels in the Valley every year," said ARB Chairman Mary Nichols. "The question we need to ask Valley residents is, have we accounted for every pollution source? Now that this report is out on the street we will be looking for public input and suggestions leading up to the Board vote later this month."

The plan reduces fine particulate matter exposure by lowering oxides of nitrogen emissions by almost 50 percent and fine particulate matter emissions by over 25 percent from 2005 levels. The plan is based on the $27 million "California Regional Particulate Matter Study," which provides the strongest scientific foundation in the nation for a particulate matter plan.

ARB, the Air District and the United States Environmental Protection Agency will participate in a technology forum to be held at University California, Merced on July 9 to explore new advancements that will be needed to obtain future reductions to meet the U.S. EPA's new more stringent standard for which a revised plan will be due in 2012. In the meantime, ARB will continue to help fund pollution-cutting projects in the Valley through Proposition 1B funds.

Fine particulate matter emissions are associated with causing a variety of health effects including premature death and a number of heart and lung diseases.

The Air Resources Board is a department of the California Environmental Protection Agency. ARB's mission is to promote and protect public health, welfare, and ecological resources through effective reduction of air pollutants while recognizing and considering effects on the economy. The ARB oversees all air pollution control efforts in California to attain and maintain health based air quality standards.

New Lung Association Study Shows $142 Billion Benefit of Converting to Zero-Emission Vehicles by 2030

The 'Road to a Cleaner Future' Study Finds Zero-Emission Vehicles Can Avoid Health Costs From Premature Deaths and Illnesses, and Reduce Global Warming Impacts

According to a studysponsored by the American Lung Association of California, $142 billion in human health and global warming reduction benefits would result from converting the entire California motor vehicle fleet from gasoline vehiclesto zero-emission vehicle (ZEV) technologies in the 2010-2030 timeframe, or $96 billion more than relying on the lowest emitting gasoline technologies. The $142 billion figure includes $38 billion in benefits to society from reduced global warming emissions.

The study, conducted by TIAX LLC, a consulting firm specializing intransportation and alternative fuels research, also found that California can avoid at least $2.2 billion per year in health costs from reduction of dangerous particulate matter by converting the motor vehicle fleet to ZEVs instead of relying on the lowest emitting gasoline technologies. This reduction in particulates means that California would annually avoid 300 cases of premature death, over 260 cases of chronic bronchitis, over 7,000 asthma attacks and more than 18,000 cases of upper and lower respiratory symptoms by moving to ZEV technology.

"Maintaining our momentum toward cleaner cars will save billions in health costs, and save lives," said Tony Gerber, MD, an American Lung Association of California volunteer. "Now is not the time for the California Air Resources Board (ARB) to weaken the state's key program that leads to cleaner vehicle technology, and cleaner air." Dr. Gerber is a pulmonary specialist and assistant professor at the University ofCalifornia, San Francisco.

American Lung Association of California Senior Policy Director Bonnie Holmes-Gen will testify on the results of the study when the ARB holds a hearing on Thursday, March 27 to consider amendments to its signature ZEV program. The California Air Resources Board (ARB) staff proposal would reduce the "pure ZEV" or "gold standard" program requirement from 25,000 to 2,500 vehicles in the 2012-2014 timeframe. The American Lung Association of California will be urging the ARB Board to reject the low volumes of "pure ZEVs" and plug-in hybrids recommended in the staff proposal.

"The Air Resources Board is at a critical juncture right now," said Holmes-Gen. "The Board has a tremendous opportunity to set a bold new vision for the ZEV program that includes strengthening the program to fully support the state's goals for both healthy air and global warming reduction."

She added, "The American Lung Association analysis provides a stark comparison of California's future transportation choices: pursuing the existing pathway of primarily gasoline vehicles or pursuing a dramatic change to widespread use of electric technology. Given the pressing need to achieve the state's global warming pollution reduction targets, the ARB should expand the ZEV program and establish a goal of integrating electric-drive technology in all new vehicles as soon as possible." The American Lung Association is urging ARB to both establish aggressive goals for introducing pure ZEVs into the vehicle fleet and pursuing much broader requirements for utilization of electric drive technologies, including conventional hybrids and plug-in hybrids in addition to hydrogen fuel cell and full function battery electric vehicles.

According to the American Lung Association of California's study, approximately 110 million tons of greenhouse gases per year could be avoided if all California vehicles were replaced with ZEVs by 2030. This would make significant progress toward the transportation sector's portion of the state goal for reducing greenhouse gases by 2050.

The study also addressed the current costs of gasoline motor vehicle use:

-- The total cost to public health and society of the existing motor vehicle fleet is over $10 billion in 2010, and this cost only drops to approximately $7 billion over the 20-year timeframe of the study with normal fleet turnover.

-- The existing motor vehicle fleet generates health costs in terms of hospitalizations, premature deaths and illnesses that add up to over $7.4 billion per year (2010), including $4.4 billion per year linked to one pollutant, nitrogen oxide (NOx).

-- The total greenhouse gas (well-to-wheel) emissions from the existing motor vehicle fleet are 150 million tons per year, and drop only to 140 million tons per year in 2030 through existing programs and vehicle turnover. This is far from the total reduction that is needed to meet California's greenhouse gas reduction goals.

"ZEVs are the road to healthier air and a sustainable transportation future," said Holmes-Gen, "and the American Lung Association of Californiais looking to the California Air Resources Board to make the vision of zero pollution transportation a reality."

About the Study:

The American Lung Association of California contracted with the firm TIAX LLC to estimate a full fuel cycle, or "well-to-wheel," analysis of greenhouse gas emissions and criteria air pollutants to develop estimates of the public health and societal costs and benefits of converting California's motor vehicle fleet to zero-emission vehicles and the cleanest gasoline vehicles (partial zero-emission vehicles, or PHEVs). TIAX LLC -- a contractor that also worked with the California Energy Commission and California Air Resources Board on various fuel use reduction and alternative-fuel analyses -- included information on emissions from each point in the process of producing, refining, transporting and utilizing the fuel. The analysis is divided into upstream well-to-tank and downstreamtank-to-wheel data for criteria pollutants and greenhouse gases. Costs to society were determined for criteria pollutant human health damages, including estimates for secondary particulate matter and global warming damages.

ARB: Diesel Soot from Trucks Major Contributor to Air Pollution

ARB reveals West Oakland health risk assessment Diesel emissions from freeway trucks are major contributors to poor air quality

OAKLAND – The Air Resources Board presented today at a public forum the preliminary results from a comprehensive health risk assessment study for the community of West Oakland. The report shows an increased potential cancer risk due to diesel particulate matter emissions from trucks traveling on nearby freeways and marine vessel traffic in the San Francisco Bay Area unrelated to the Port of Oakland.

The study, developed in collaboration with the Bay Area Air Quality Management District, the Maritime Port of Oakland and Union Pacific Railroad, reveals that the estimated lifetime potential cancer risk for residents of West Oakland from exposure to diesel emissions is about 1,200 excess cancers per million people. The analysis covers 3.1 million people who reside in the affected area of 3,800 square miles.

While diesel trucks account for a majority of the risk in West Oakland resulting in about 850 potential cancer cases per million or 70 percent, port operations account for an estimated lifetime potential cancer risk of 200 excess cancer cases per million, or about 15 percent of the total. Union Pacific railyard emissions amount to a potential cancer risk of about 40 excess cancer cases per million, or less than 5 percent and the remaining 10 percent of risk comes from a variety of diesel sources such as passenger trains and construction projects.

"This health risk assessment will provide the community the focus and momentum needed to mobilize and combat air pollution," said ARB Chairman Mary D. Nichols. "We look forward to working with community activists to converge on the main pollution culprits, such as trucks motoring on nearby freeways, affecting a growing and vibrant West Oakland."

In the development of the ship emissions, ARB staff used transponder data (continuously reports ship location) to more accurate estimate where off-shore emissions are occurring. For the first time in a large risk assessment, a regional wind field was generated using data from 30 onshore and 3 offshore weather stations. The CALPUFF model was used to estimate the ambient concentration of diesel particulate matter. This model is capable of producing more precise results than the models used in the past due to its ability to account for highly varying wind fields and complex terrain.

Emissions from diesel particulate matter are associated with causing a variety of health effects including premature death and a number of heart and lung diseases. The study also estimates the yearly non-cancer health impacts resulting from exposure to port-related diesel particulate matter emissions in the area: 18 premature deaths (age 30 and older), 290 asthma attacks, 2,600 days of work loss, and 15,000 minor restricted activity episodes.

Having identified diesel particulate matter as a toxic air contaminant in 1998 due to its potential to cause cancer and other respiratory problems, ARB has put in place stringent regulations to curve the health risk to Californians. The most recent adopted regulations to limit diesel emissions affect cargo handling equipment, transport refrigeration units, truck idling, off-road equipment, harbor craft, ship auxiliary engines, port drayage trucks and ships-at-berth. Also, the introduction of cleaner fuel for railroads and ships has contributed to lower pollution around the ports and railyards.

Later this year, ARB will be considering proposed regulations involving on-road heavy duty diesel vehicles (trucks and buses) and ocean-going vessel main engines to further reduce diesel soot. State control measures will contribute to an approximate decrease of 80 percent in harmful emissions by 2015.

ARB, British Council announce California Climate Champions

ARB Chairman Mary Nichols and the British Council introduced California’s 15 Climate Champions today during a rooftop ceremony at the Cal EPA Building in Sacramento.

Based on a similar program started in the United Kingdom, California’s champions will educate peers, fellow students and communities on the impacts of climate change along with steps they can take at the individual level to reduce their carbon emissions. Typical measures include energy efficiency steps at home, recycling and encouraging carpooling and public transit.

"These amazing, inspirational teens have rightfully accepted global warming as the challenge of their generation, and they want to lead the charge on solutions," said ARB Chairman Mary Nichols. "While ARB will take care of the regulatory approach to cutting California’s greenhouse gas emissions, we’ll be counting on the champions to help effect change household to household."

ARB and British Council staff interviewed more than three dozen high school students – and reviewed many more applications – in selecting the 15 teenagers who were announced today. The judges selected the winners based on their knowledge of the topic, their enthusiasm to effect change and their communications skills.

Three of the champions (Rebecca Chan, Sophia Angelis and Marvin Salazar) will travel to London next week to meet with other Climate Champions from 12 other countries, and then will fly to Kobe, Japan in May to attend a summit of the G8 environment ministers. All 15 will participate in a "climate camp" in California this summer and engage in an on-line peer network to share ideas and encourage others to get involved.

ARB Tripling Early Action Measures Set by AB 32

Projects would net 3 million metric tons of additional greenhouse gas emissions

SACRAMENTO - The Air Resources Board today approved staff's proposal to triple the set of early measures to help meet the state's goal of reducing greenhouse gas emissions roughly 25 percent by 2020 as required by the Global Warming Solutions Act (AB 32).

Last month, ARB staff proposed an additional set of measures, including many that go above and beyond the narrow requirements of the law. New measures approved today are expected to reduce greenhouse gases from the trucking industry, greener ports, cement and semiconductor industries, and consumer products.

"Today's Board approval marks another significant milestone in our goal to return the state's greenhouse gas emissions to 1990 levels by 2020," said ARB Chairman Mary Nichols. "Today's measures include many common-sense, practical approaches that will continue our forward momentum on AB32. California is showing the country and the world that we can and will help reverse the ominous tide of global warming."

The newly approved measures include:
* Smartway Truck Efficiency: Requires existing trucks and trailers to be retrofitted with devices that reduce aerodynamic drag, thus reducing 1.3 million metric ton reductions in greenhouse gas equivalents as well as reducing fuel consumption.

Firms such as UPS and Whole Foods have enjoyed great success with this program at the national level with the U.S. EPA.

* Port electrification: This measure will require docked ships to shut off their auxiliary engines by plugging into shoreside electrical outlets. Already offered as a NOx and diesel PM reduction effort used at the ports of Long Beach/Los Angeles and Oakland, this project will also reduce greenhouse gas emissions by 500,000 metric tons every year.

* Reduction of perfluorocarbons from the semiconductor industry: Extremely potent greenhouse gases, PFCs are used in the semiconductor industry to create intricate circuitry patterns on silicon wafers and to rapidly clean semiconductor chemical vapor chambers. Alternative chemistry development, emissions abatement and recovery and recycling will lessen greenhouse gas emissions by 500,000 metric tons annually.

* Reduction of propellants in consumer products: Aerosols, tire inflators, electronics cleaning and dust removal products all contain propellants that contribute an estimated 300,000 metric tons of greenhouse gas emissions in California every year. Manufacturers can help by switching from HFC propellants to others with lower climate impact.

* Tire inflation: ARB will craft regulations requiring tune-up, smog check and oil change mechanics to ensure proper tire inflation as part of overall service. By ensuring that tire pressure in cars throughout the state is maintained to manufacturer specifications, California will see a 200,000 metric tons reduction in greenhouse gas emissions.

* Sulfur Hexafluoride (SF6) reductions from non-electricity sector: ARB proposes to ban the use of SF6 from non-essential uses if viable alternatives are available. SF6 is currently used in manufacturing processes with aluminum, magnesium and semiconductors, as well as a tracer for air quality and vehicle studies.

The new measures are projected to reduce about 3 million metric tons of annual greenhouse gas emissions. Combined with the early action measures adopted by the Board in June - a low carbon fuel standard, restrictions in do-it-yourself air conditioner repairs and methane capture from landfills - ARB now has measures in the works to reduce statewide greenhouse gas emissions by nearly 16 million metric tons.

The proposed early actions combined with other measures proposed by the larger Climate Action Team could reduce greenhouse gas emissions by more than 36 tons by 2020, roughly 21 percent of the total needed to meet AB 32's goal of rolling back emissions to 1990 levels. This lays a solid foundation for obtaining the necessary reductions needed to meet AB 32 requirements.

Governor Schwarzenegger signed the Global Warming Solutions Act on Sept. 26, 2006, establishing the world's most comprehensive greenhouse gas reduction initiative. The law requires the ARB to implement a statewide greenhouse gas emissions reduction strategy. In addition, the Governor directed the members of the Climate Action Team to work alongside the ARB to reduce greenhouse gas emissions from their respective jurisdictions.

ARB Considers Alternative Fuel Incentives

SACRAMENTO - Expedited development of alternative fuels received a boost today as the Air Resources Board (ARB) considered options on how to best spend $25 million allocated by new state legislation to reduce air pollution and greenhouse gas emissions.

"With the threat of global warming and today's unstable political climate affecting our resources, fully exploring use of alternative fuels is a top priority," said ARB Chairman Dr. Robert F. Sawyer. "Thanks to forward thinking and sound science, California sets an example for the country and for the world. We are excited by all the possibilities and challenges ahead, and hope that our efforts will help to further diversify and enhance our future energy options."

Assembly Bill 1811, which amends and supplements the Budget Act of 2006, directs the ARB to develop a joint plan with the California Energy Commission (CEC) to spend $25 million to provide incentives for the use and production of alternative fuels. The proposed allocation amounts were guided by the budget language and input from ARB and the CEC. The legislation requires the funds to be awarded by June 30, 2007, and no funds can be awarded for projects that include fuels derived from petroleum, coke or coal.

As proposed to the Board today, the $25 million will be generally allocated as follows, with final amounts assigned on a project-by-project basis:

- $8.5 million for alternative fuel vehicles (including demonstration programs for plug-in hybrids and clean transit buses);
- $7 million for fueling infrastructure (including incentives for E-85 and other alternative fuels);
- $5 million for biofuels production;
- $3.5 million for fuel/vehicle research (including emissions testing and vehicle performance and vapor recovery certification), and
- $1 million for education.

A public workshop on the funding program was held in September that drew more than 100 participants. Solicitations for projects are expected to be sent out in January, 2007, with decisions on the final slate of projects to be made next Spring. All funds must be expended by June 30, 2009.
