I E S E L EXHAUST IN NEW ENGLAND WHO IS AT RISK? WHAT CAN YOU DO? c/EPA Ncu Lnuland ------- IESEL EXHAUST & YOUR HEALTH * <» HAT CAN O Turn off engines when vehicles are not in motion. © Retrofit engines with pollution control devices and use cleaner burning fuel. ©When purchasing new vehicles, buy the lowest emitting vehicles available. O Keep engines well tuned and maintained. For more details about how to take these steps, visit: www.epa.gov/ne/ eco/diesel/, or call 1-800-821-1237. Diesel exhaust contains significant levels of small particles known as fine participate matter. Fine particles are so small that several thousand of them could fit in the period at the end of this sentence. In New England, diesel engin are the third largest human- source of fine particles, contrib uting more than 20 percent of fine particle emissions. Fine particles in the air are a serious public health problem. They pose a significant health risk because they can pass through the nose and throat and lodge themselves in the lungs. These fine particles can cause lung damage and premature death. They can also aggravate respir- atory conditions such as asthmc and bronchitis. Nationwide, particulate matter, especially fine particles, is responsible for 15,000 premature deaths every year. Also, diesel exhaust is likely to cause cancer in humans. WHO IS MOST AT RISK? People with existing heart or lung disease, asthma or other respirJi tory problems are most sensitive to the health effects of fine particles. The elderly and children are also at risk. In general, children are more sensitive to air pollution because they breathe 50 percent more air per pound of bodyweightthan adults. ------- . OTHER HEALTH AND ENVIRONMENTAL EFFECTS Fine particles from diesel engines contribute to haze which restricts our ability to see long distances. Diesel exhaust also contributes to ozone formation (or smog), acid rain, and global climate change. t (EDUCING EMISSIONS IDLING A typical heavy-duty truck or bus can burn approximately one gallon of diesel fuel for each hour it idles, generating significant amounts of pollution, wasting fuel, and causing excessive engine wear. Instead of idling, vehicle owners can purchase small generators or auxiliary power units that provide heat, air conditioning, and/or power while a vehicle is not in motion. These devices substantially reduce the fuel consumed and emissions generated during long- duration id ling. Also, vehicle owners can purchase electric starting aids such as block heaters which help warm the engine to avoid starting difficulties and reduce idling time during engine warm-up. RETROFITS AND CLEANER FUELS To reduce pollution from existing trucks and buses, vehicle owners can use ultra-low sulfur diesel fuel in combination with pollution control equipment such as particulate matter filters. Although ultra-low sulfur diesel fuel is not required until 2006, it is currently available in parts of New England. In some cases, this approach can reduce particulate matter emissions by more than 90 percent. NEW VEHICLE PURCHASES - WHAT TO CONSIDER 'ehicles that meet EPA's 2007 emission standards ahead of schedule. WH V Vehicles equipped with devices that minimize idling and warm- up time automatically. Vehicles that run on cleaner fuels like compressed natural gas. ------- w HAT IS GOVERNMENT DOING? Diesel engines are a durable and economical source of power. EPA and the New England States are taking important steps to advance cleaner diesel engines. EPA is requiring reductions of diesel pollution from new heavy-duty diesel trucks and buses. In 2006, diesel fuel will contain 97 percent less sulfur. This ultra-low sulfur diesel fuel in combination with advanced pollution control technology will mean that in 2007, new trucks and buses rolling off the production lines will be up to 95 percent cleaner than today's models. EPA has issued emission standards for new, non-road diesel engines, such as construction and farm equipment, and is working to strengthen these standards in the future, * Because emission reductions from cleaner vehicles take time to have an influence, EPA and the New England states are working to: O Retrofit existing diesel vehicles with pollution controls. @ Implement emission testing programs for diesel vehicles. > Create and implement anti-idling programs. & Promote cleaner fuels like compressed natural gas.
