The EPA is drafting new rules to reduce dangerous emissions from bulldozers, tractors, and other diesel powered equipment. The rules would force engine manufacturers to install state of the art devices for capturing and treating exhaust gases, and require oil refiners to produces a low-sulfur diesel fuel required for anti-pollution devices. An EPA administrator announced last August two, cost-effective clean air programs that reduce pollution from diesel engine. The new standards will provide a long term improvements in the nation's air quality. The agency said "both new diesel programs, one, a final emission reduction standard for all diesel trucking companies, the other proposal is to phase tighter emission limits for non-road diesel engines.
New federal emission regulations affect some of the 2002 heavy-duty diesel engines, which have now incorporated new emission control technologies. The "benchmarking program" will extensively test the performances, emissions in two types of class in diesel engine. The two class, one, is heavy-duty diesel engines from 450 horsepower an up, the second is light-duty diesel engines, around 300 horsepower these are the diesel engine sold in the US for Rams, F-350's, and K3500. .
The proposed rules are to be formally announced this spring, that would slash off-road diesel emissions by as much as 95 percent and bring them in line with newly adopted standards for heavy-duty diesel trucks. Off-road diesel engines are among the largest sources of pollutants that these pollutants have been linked to lung cancer, asthma, and other serious illness, according to the EPA. "The proposed rules would save an estimated 8,300 lives a year and tens of billions of dollars annually in medical costs and lost workdays, according to the government.".
The diesel fuel used in off-road equipment has a high-sulfur contain of 3,000 parts per million that clogs anti-pollution devices, and contributes to harmful pollution particles.
