ARB Proposes World's Strictest Regulation Curbing Emissions from Ocean-Going Vessels

If passed, rule would prevent thousands of premature deaths annually

The California Air Resources Board has released a proposed regulation that would require ocean-going vessels within 24 nautical miles off California's coastline to use cleaner fuel in their main and auxiliary engines, and boilers.

The measure to be considered by the Air Resources Board at its July 26 and 27 meeting would annually affect about 2,000 ocean-going vessels visiting California. The vessels would be required to use lower-sulfur marine distillates rather than the highly polluting heavy-fuel oil often called bunker fuel.

"The gains made by this regulation will save lives all along the coast and provide significant health benefits for those living near heavily used California seaports." explained ARB Deputy Director, Michael Scheible. "We're requiring very large reductions that will greatly lessen air pollution from ships."

The proposed regulation requiring ships to use more refined fuel with lower sulfur content would be implemented in two steps - first in 2009 and final in 2012 - and would be the most stringent and comprehensive requirement for marine fuel-use in the world. Both U.S.-flagged and foreign-flagged vessels would be to subject to the statewide regulation.

The draft regulation would reduce emissions of toxic particulate matter from the vessels' diesel engines by 15 tons per day, an 80 percent reduction of the uncontrolled emissions now. Emissions of oxides of sulfur and nitrogen, major contributors to California's air pollution problems, would also be reduced by 90 and six percent, respectively.

The proposed regulation would have large health benefits for Californians. An estimated 2,000 premature deaths between 2009 and 2015 would be avoided, and the cancer risk caused by emissions from these vessels would be reduced by over 80 percent. In addition, the emission reductions would aid the South Coast Air Quality Management District meet federal clean air requirements for fine particulate matter by 2014. The regulation is also needed for ARB to achieve its targeted 85 percent reduction of diesel PM by 2020.

Diesel exhaust contains a variety of harmful gases and over 40 other known cancer-causing substances. Currently, diesel PM emissions from ocean-going vessels expose over seven million people in California to high cancer risk levels - in excess of 100 in a million for lifetime exposures.

To reach its goal of reducing diesel PM throughout California, over the past eight years ARB has adopted regulations affecting cargo-handling equipment, transport refrigeration units, truck idling, off-road equipment, harbor craft, port drayage trucks, onboard incineration, and ships at-berth. ARB's cleaner fuel requirements for railroad and ship engines have reduced pollution around rail yards and ports. And this fall ARB will consider measures to reduce emissions from heavy duty diesel trucks.

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.

Government Takes Action for Cleaner Air: Air Quality Alert System Expanded to 5.3 Million People Living in the Greater Toronto Area

BURLINGTON, ONTARIO - June 6, 2008 - Mike Wallace, Member of Parliament for Burlington, on behalf of Canada's Environment Minister John Baird, and Health Minister Tony Clement, today announced that the world's first Air Quality Health Index is being expanded to six communities in the Greater Toronto Area.

"Canadians are entitled to clean air, to know the quality of the air they breathe and what they can do to reduce harmful impacts of air pollution," said Mr. Wallace. "

A year ago our Government announced $30 million to establish an alert system across the country to provide Canadians with the tools they need to make the right decisions for their families. This investment, combined with our Turning the Corner plan to cut air pollution from industry by 50 per cent, shows how serious we are about cleaning up the air we breathe and improving the health of Canadians."

Canada's Air Quality Health Index, found at http://www.airhealth.ca/, provides real time information to Canadians on the quality of the air they're breathing. It is a key tool in preventing injury and illness to those with asthma or other respiratory illnesses. The project is supported jointly by the Governments of Canada and Ontario, along with Toronto Public Health. In July 2007, the Government of Canada announced the 18-month pilot project for Toronto.

"Ontario is a world leader when it comes to fighting air pollution and protecting the health of its citizens," said Ontario Environment Minister John Gerretsen. "As a province, we support the pilot Air Quality Health Index because we want citizens in the Greater Toronto Area and other cities to have access to the most accurate information possible on the health risks of poor air.

"Today's announcement is part of a clean air initiative across Canada where Member of Parliament Ed Fast announced that the British Columbian pilot project is moving from a pilot program to full implementation. British Columbians in 14 communities across the province will now have access to the most up to date air quality information available.With federal funding of $30 million over four years, the Air Quality Health Index will be rolled out to other mid- and large-sized communities across the country. Federal partnerships with municipal and provincial and governments and non-governmental organizations partnerships are key to the program's success in Ontario, essential air quality monitoring data and assistance with forecasting the health index is provided by the Ontario Ministry of the Environment.

This announcement compliments the Governments other clean air initiatives including the launch of a national vehicle scrapage program to get smog-producing cars off the road, tough new emissions standards to reduce air pollution from cars and limits on smog-producing chemicals in everyday products.

Is Air Pollution Associated with Ventricular Arrhythmia?

Introduction: Premature ventricular complexes are a normal finding in healthy individuals and the prevalence increases with age and is more common in men. Premature ventricular complexes can occur in association with a variety of stimuli, and a lesser known cause is the association between air pollution and ventricular arrhythmias.

Case presentation: A previously healthy man started to ride a lightweight motorbike in heavy traffic.

A few weeks later he was admitted to hospital with premature ventricular complexes in bigeminy, which decreased after a few days when he was not exposed to exhaust fumes. A few weeks later he started using the motorbike again and the same symptoms developed once more, only to subside when he stopped riding in heavy traffic.

Conclusions: Studies have shown an association between air pollution and premature ventricular complexes and other kinds of arrhythmias.

The mechanism may be changes in cardiac autonomic function, including heart rate and heart rate variability. Air pollution should be considered when patients present with arrhythmias and no other causes are found.

Breathing Dust and Soot Raises Risk of Stroke

ANN ARBOR, Michigan, June 2, 2008 - Short-term exposure to low levels of particulate air pollution may increase the risk of stroke or mini-stroke, according to new research conducted in Texas that suggests current exposure standards are not sufficient to protect the public. Stroke is the third leading cause of death in the United States.

The study examined particulate air pollution in the southeast Texas community of Corpus Christi where there is a large petroleum and petrochemical industry presence.

The results showed what the researchers called "borderline significant associations" between same day and previous day exposures to fine particulate matter and risk of ischemic strokes.

Ischemic (is-skeem-ic) stroke occurs when an artery to the brain is blocked.

In the study, researchers identified ischemic strokes and also transient ischemic attacks, or TIA, sometimes called mini strokes, that often lead to a stroke later.

Findings suggest that recent exposure to fine particulate matter may increase the risk of these types of stroke events specifically.

Particulate matter is a combination of fine solids such as dirt, soil dust, pollens, molds, ashes, and soot; and aerosols that are formed in the atmosphere from gaseous combustion by-products such as volatile organic compounds, sulfur dioxide and nitrogen oxides.

Particulate pollution comes from such diverse sources as factory and utility smokestacks, vehicle exhaust, wood burning, mining, construction activity, and agriculture.

"The vast majority of the public is exposed to ambient air pollution at the levels observed in this community or greater every day, suggesting a potentially large public health impact," said Lynda Lisabeth, lead author and assistant professor in the University of Michigan School of Public Health, where the research is based.

Despite the fossil fuel industry in the area, fine particulate matter exposures were low relative to other regions of the country, the researchers said probably because of the proximity to the coast and prevailing wind patterns.

Lisabeth stressed that the association requires further study in other areas with varying climates and alternative study designs.

Ischemic stroke is by far the most common kind of stroke, accounting for about 88 percent of all strokes. Stroke can affect people of all ages, including children.

Many people with ischemic strokes are 60 or older, and the risk of stroke increases as people age. At each age, stroke is more common in men than women, and it is more common among African-Americans than white Americans.

For this study, researchers looked at data from the Brain Attack Surveillance in Corpus Christi Project, a population-based stroke surveillance project designed to capture all strokes in Nueces County, Texas.

Ischemic stroke and TIA cases between 2001 and 2005 were identified using trained staff and later verified by neurologists.

Daily historical air pollutant and meteorological data were obtained for the same time period from the Texas Commission on Environmental Quality's Monitoring Operations database.

Data on fine particulate matter and ozone from a centrally located monitor in Corpus Christi located upwind of the local industrial facilities was used in the study.

The majority of stroke and TIA cases were found to be located upwind of local chemical plants and refineries.

Some research has shown that particulate air pollution is associated with acute artery vasoconstriction and with increased thickening of the blood, which may enhance the potential for blood clots.

Similar associations were also seen with ozone, another type of air pollution.

This study confirms earlier research showing that exposure to fine particle matter air pollution increases a person's risk for hospital admission for cardiovascular and respiratory diseases.

The study, "Ambient Air Pollution and Risk of Ischemic Stroke and TIA," will be published in the July 2008 issue of Annals of Neurology http://www.interscience.wiley.com/, the official journal of the American Neurological Association.

Environmental Groups Petition to Overturn EPA Ozone Standard

WASHINGTON, DC, May 28, 2008 - Health and environmental advocates filed a lawsuit Tuesday challenging the U.S. Environmental Protection Agency's refusal to adopt stronger standards for ground-level ozone proposed by the agency's own scientists.

The American Lung Association, Natural Resources Defense Council, Environmental Defense Fund, the National Parks Conservation Association, and the Appalachian Mountain Club are taking issue with the standards adopted by the federal environment agency in March.

The standards for ozone pollution, one of the components of smog, are not only far weaker than those unanimously recommended by EPA science advisors, but also leave public health and the environment at great risk, the groups contend.

"EPA officials ignored the advice of their own scientists when they chose these deficient standards, but they can't ignore the law," said attorney David Baron with the public interest law firm Earthjustice who filed the lawsuit in the U.S. Court of Appeals for the Washington, DC Circuit.

"The Clean Air Act requires EPA to adopt standards strong enough to protect our lungs and our environment. We're fighting to make sure that happens," Baron said. "Stronger standards could save thousands of lives, by some estimates."

EPA Administrator Stephen Johnson is already under suspicion of bowing to White House pressure to reject stronger smog standards. Johnson was grilled last week by members of the U.S. House Committee on Oversight and Government Reform who asked why he rejected the advice of scientists in setting the standard.

Before the committee on May 20, Johnson defended his actions and insisted that he was solely responsible for the smog decision. He declined to provide details about his meetings with the president and other White House officials.

"I have routine meetings with the executive branch including the president … those meetings are in confidence," Johnson told the committee.

Johnson testified beside the head of EPA's Clean Air Scientific Advisory Committee, Dr. Rogene Henderson, who critiqued Johnson's actions, telling committee members, "Policymakers wandered into science and they did not do it well."

"Willful ignorance triumphed over sound science," Henderson told the legislators.

Henderson's Clean Air Scientific Advisory Committee had recommended that the EPA set the health standard at between 60 and 70 parts of ozone per billion parts of air.

Instead, Johnson and the EPA set the standard at 75 parts per billion.

In their petition for review of the EPA ozone standard, the groups contend that the 75 parts per billion standard leaves asthmatics, young children, the elderly and others at greater risk for lung and heart disease than the standard recommended by the Clean Air Scientific Advisory Committee .

Smog is linked to premature deaths, thousands of emergency room visits, and tens of thousands of asthma attacks each year. Ozone is especially dangerous to small children and senior citizens, who are often warned to stay indoors on polluted days.

Exposures of less than 24 hours to current levels of ground-level ozone in many areas are likely to contribute to premature deaths, according to a National Research Council report published on Earth Day 2008.

Evidence of a relationship between exposures of less than 24 hours and mortality has been mounting, but interpretations of the evidence have differed, prompting the EPA to request the Research Council report.

The committee that wrote the report was not asked to consider how evidence has been used by the EPA to set ozone standards, but the evidence is strong enough that the EPA should include ozone-related mortality in health-benefit analyses related to future ozone standards, said the committee.

"Ozone pollution threatens breathing for millions of Americans, especially children, the elderly and people with lung disease including asthma," said Bernadette Toomey, President and CEO of the American Lung Association. "The EPA's decision to disregard the overwhelming evidence and the advice of respected experts is a decision that we could not allow to go unchallenged."

Some Biofuels Might Do More Harm than Good to the Environment

Biofuels based on ethanol, vegetable oil and other renewable sources are increasingly popular with government and environmentalists as a way to reduce fossil fuel dependence and limit greenhouse gas emissions.

But new research led by a biologist at the University of Washington, Bothell, shows that some of the most popular current biofuel stocks might have exactly the opposite impacts than intended. The authors of a paper published in the June issue of the journal Conservation Biology offer a dozen policy recommendations to promote sustainability and biodiversity in biofuel production.

The study looked at factors such as the energy needed to produce a renewable fuel source compared with how much energy is produced, the impact on soil fertility and effects on food supply when fuels based on crops such as corn and soybeans are mixed with fossil fuels. Based on those factors, the authors determined that corn-based ethanol is the worst alternative overall.

"It's foolish to say we should be developing a particular biofuel when that could mean that we’re just replacing one problem with another," said lead author Martha Groom of the UW Bothell. Co-authors are Elizabeth Gray of The Nature Conservancy and Patricia Townsend of the UW Seattle.

The authors argue that precise calculations are needed to determine the ecological footprints of large-scale cultivation of various crops used for biofuels.

They note, for example, that because such large amounts of energy are required to grow corn and convert it to ethanol, the net energy gain of the resulting fuel is modest. Using a crop such as switchgrass, common forage for cattle, would require much less energy to produce the fuel, and using algae would require even less. Changing direction to biofuels based on switchgrass or algae would require significant policy changes, since the technologies to produce such fuels are not fully developed.

The paper's policy suggestions are "not definitive at all," Groom said, "but rather each category calls out a question and is a starting point in trying to find the proper answers."

These concerns are becoming more acute with the rapid rise of both food and fuel prices, she said. The issue is especially touchy for farmers who might for the first time be realizing significant profits on their crops, but it also is a serious concern for motorists.

"I've heard about people getting their gas tanks siphoned, and I hadn't heard of that since the '70s," she said.

A difficulty, Groom said, is that while escalating prices add pressure to find less costly fuel sources, acting too hastily could create a host of other problems. For example, farmers who plant only corn because it is suddenly profitable, and don't rotate with crops such as soybeans, are likely to greatly deplete their soil, which could limit crop growth and promote soil erosion.

Also, some plants are better than others for absorbing carbon dioxide from the atmosphere, while others perhaps need more cultivation, which requires more fossil fuel for farm equipment. In addition, fertilization, watering and harvesting all require energy.

The study took about a year to conduct and is a synthesis of peer-reviewed research published in a various journals. The scientists examined the literature looking for indicators of biofuels that are more sustainable and carry a smaller ecological footprint, then used that information to derive the policy recommendations.

The primary audiences for the work are policy makers, students and other biologists, Groom said. The primary goals are to establish a logical basis to evaluate options for biofuel development and to spur new research to find the most ecologically promising alternatives.
"We don't want to make new mistakes. If we don't ask the right questions to start with, we're going to replace old problems with new ones," she said.

Policy Recommendations:
• Calculate a biofuel's ecological footprint
• Promote only biofuels that can be produced sustainably
• Select highly efficient species for biofuels
• Work to minimize land needed for biofuels
• Encourage reclamation of degraded areas
• Prohibit clearing areas for more cultivation
• Promote use of energy crops that require less fertilizer, pesticide and energy
• Promote native and perennial species
• Prohibit use of invasive species
• Promote crop rotation on cultivated lands
• Encourage soil conservation
• Promote only biofuels that are at least net carbon neutral

Particulates Cause More Premature Deaths than Previously Thought

More premature deaths than previously thought from particles in vehicle exhaust New research reveals significant new information

The California Air Resources Board was presented with research today showing long-term exposures to fine particle pollution pose a greater health threat than previously estimated.

Annually, 14,000 to 24,000 premature deaths are estimated to be associated with exposures to PM2.5, a mix of microscopic particles less than 2.5 microns in size. A majority of these deaths occur in highly populated areas around the state, including the South Coast, San Joaquin Valley and San Francisco Bay air basins.

"Particle pollution is a silent killer," said ARB Chairman Mary D. Nichols. "We must work even harder to cut these life-shortening emissions by further addressing pollution sources head-on."
Particulate matter (PM) is a complex blend of substances ranging from dry solid fragments, solid-cores fragments with liquid coatings, and small droplets of liquid. These particles vary in shape, size and chemical composition, and may include metals, soot, soil and dust.

At the request of the board in 2006, ARB researchers carefully reviewed all scientific studies on the subject and consulted with health scientists. While exposures to particulate matter have long been known as a serious health threat, new information suggests that the pollutant is even more toxic than previously thought.

Hospitalizations, emergency room visits and doctor visits for respiratory illnesses or heart disease have been associated with PM2.5 exposure. Other studies suggest that PM2.5 exposure may influence asthma symptoms and acute and chronic bronchitis.

Children, the elderly and people with pre-existing chronic disease are most at risk of experiencing adverse health effects from PM2.5 exposure. Even small increases in PM2.5 exposures may increase health risks.

Major contributors to PM2.5 include trucks, passenger cars, off-road equipment, electric power generation and industrial processes, residential wood burning, and forest and agricultural burning. All combustion processes generally produce PM2.5.

While the new data reveals a greater threat from PM2.5, the state's previous efforts to reduce emissions throughout the state have been successful. The ARB in coordination with the 35 air districts throughout the state continues to develop and implement strategies of aggressive air pollution control. These measures have been so effective for the last two decades that PM exposures have been reduced in California's major populated areas. Since the official year-round monitoring of ambient PM2.5 began in 1999, concentrations have decreased 30 percent across California, most notably in the South Coast and the San Joaquin Valley regions.

Additionally, in 2000 ARB adopted an aggressive risk reduction plan that targets all diesel PM sources in California. As part of the plan, cleaner diesel fuels and new diesel engines (both on-road and off-road) have been developed. In concert with regulations aimed at requiring cleaner new engines, other regulations have been adopted to address diesel engines already on the road, including those in waste collection vehicles, transit fleet, school buses, stationary engines, transport refrigeration units and portable engines. Later this year, ARB will consider rules to significantly cut diesel particulate emissions from private truck fleets.

ARB Approves the Distribution of $221 Million of Proposition 1B Funding

Projects estimated to reduce nearly 30,000 tons of pollution

FRESNO - The Air Resources Board approved today the final list of diesel emission reduction projects to be funded by the first installment of $221 million out of the $1 billion from voter-endorsed Proposition 1B.

ARB voted to distribute $221 million among California's four trade corridors based on the funding targets adopted last February. The allocation will place $122 million for the Los Angeles/Inland Empire; $55 million for the Central Valley; $31 million for the Bay Area; and $13 million for the San Diego/Border region.

The dissemination by categories would result in a total of:
$198.4 million to upgrade over 8,200 trucks with cleaner equipment and engines
$16.5 million for 18 new locomotives
$2.5 million for shore electric power for cargo ships docking at the Port of San Diego
$4.3 million for 17 freight-related harbor craft

"This is a grand move toward our ultimate goal of cleaning up the air," said ARB Chairman Mary D. Nichols. "With regulations in place and funding for early compliance, California is on its way to significantly reduce the number of people affected by diesel soot."

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 and to further the state's progress towards meeting air quality goals.

Over their life, the projects to be funded are estimated to reduce nitrogen oxide emissions by 26,900 tons and particulate matter by 1,800 tons. ARB and the local agencies administering the monies will focus on projects that quickly reduce emissions and achieve benefits throughout the state, such as directing 94 percent of the total to cleaner trucks and locomotives that may travel within multiple corridors.

The awards to eligible local agencies and projects were made official at today's public hearing in Fresno. Earlier this year, the ARB released $25 million in early grants to five air districts to upgrade 1,000 trucks and install shore-based electrical power at two ship berths.

ARB Chairman Mary Nichols applauds Senator Boxer's bill

Mary Nichols, Chairman of the California Air Resources Board, issued the following statement about Senator Boxer's new bill that would reverse the EPA decision denying California's request to be allowed to implement its regulations minimizing greenhouse gas emissions from autos. This follows revelations from a report issued by the house of representatives Committee on Oversight and Government Reform, chaired by Representative Henry Waxman, that after communications with the White House, Administrator Johnson reversed his original decision -- supported fully by USEPA staff -- to grant California a waiver to enforce its clean car law .

"We applaud the fact that Senator Boxer's bill to overturn administrator Johnson's illegal denial of California's waiver request made it out of the committee. This is a significant step forward but only one skirmish in the battle to secure our rights and protect the environment. We will continue to fight for the waiver in the courts, we will press our case with the public, and we will not stop demanding that the federal administration's obey the law. Fourteen states representing almost half the vehicles in the nation and tens of millions of consumers need clean cars now that reduce greenhouse gases and save money at the pump. "
