newsrel -- Landmark Rule to Reduce Diesel Emissions Posted: 26 Jul 2007 18:49:40
Please consider the following Air Resources Board press release announcing the Board's decision regarding in-use off-road diesel engines. ____________________________________________________________ Release 07-26 FOR IMMEDIATE RELEASE July 26, 2007 Leo Kay (916) 322-2990 Karen Caesar (626) 575-6728 www.arb.ca.gov ARB adopts landmark rule to reduce toxic emissions from off-road equipment SACRAMENTO - The California Air Resources Board today adopted a pioneering regulation aimed at reducing toxic and cancer-causing diesel emissions from the state's estimated 180,000 "off-road" vehicles used in construction, mining, airport ground support and other industries. "This regulation will prevent thousands of premature deaths and reduce health care costs for those suffering from respiratory disease such as asthma," said Mary Nichols, ARB Chairman. "It is also the first of its kind in the nation, and, as has occurred with other California regulations, could serve as a model for other states to follow." Diesel particulate matter, or diesel "soot," was identified as a toxic air contaminant in 1998. In 2000, the ARB established California's Diesel Risk Reduction Plan, which aims to reduce diesel emissions to 85 percent below 2000 levels by 2020. Other sources of diesel particulate matter such as transit buses, trash trucks, cargo-handling equipment and ship auxiliary engines have already been addressed through regulations, along with diesel fuel. Because many diesel engines lack emission controls and can remain in use for 30 years or longer, they will remain a major contributor to air pollution for years to come. The regulation adopted today will dramatically reduce emissions by installation of diesel soot filters and encouraging the replacement of older, dirtier engines with newer emission controlled models. By 2020, diesel particulate matter will be reduced by 74 percent and smog forming oxides of nitrogen by 32 percent, compared to what emissions would be without the regulation. The new rule also includes a provision allowing areas that are currently unable to achieve clean air standards set by the US EPA for particulate matter to opt in to stricter regional requirements if incentive funds are made available. The air districts that could take advantage of this provision are the South Coast Air Quality Management District and the San Joaquin Valley Air Pollution Control District; both are considered "non-attainment areas" for particulate matter. Depending on the amount of incentive money made available, these provisions could as much as a double the NOx emissions benefits in these districts, setting them on a faster track to meeting their clean air goals. The requirements and deadlines vary depending on fleet size. For small fleets, which include small businesses or municipalities with a combined horsepower of 2500 or less, implementation does not begin until 2015. Medium fleets, with 2501 to 5000 horsepower, have until 2013, while large fleets, with over 5000 horsepower, must begin complying in 2010. Affected vehicles include bulldozers, loaders, backhoes and forklifts, as well as many other self-propelled off-road diesel vehicles. ARB performed a comprehensive economic analysis of the rule's impact on business, concluding that the regulation will cost industry up to $3.5 billion over its lifetime. Staff reviewed individual companies' financial records and conducted numerous workshops to discuss the cost of the regulation as well as impacts on individual businesses. ARB also gave special consideration to small businesses (e.g., small fleets have until 2015 to begin compliance, while large fleets must begin in 2010) to ensure that the regulation would not provide undue economic hardship. The Board's action today also sets the stage for efforts next year to develop similar requirements for the hundreds of thousands of on-road trucks that travel on California's roads every day. According to ARB estimates, over its course, this rule will prevent at least 4,000 premature deaths statewide and avoid $18 - $26 billion in premature death and health costs. 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. #####
