Web Site Helps Diesel Truck, Bus Fleets Run Cleaner
A new Web site from the U.S. Environmental Protection Agency provides information on retrofitting diesel vehicles to help fleets run more cleanly.
A new Web site from the U.S. Environmental Protection Agency provides information on retrofitting diesel vehicles to help fleets run more cleanly.
Nationwide, heavy duty diesel vehicles contribute 15% of the nation's emissions of smog-causing nitrogen oxides and 22% of particulate matter, or soot, emissions. In urban areas, their contribution to air pollution can be even greater. An older, dirtier diesel truck or bus can emit almost eight tons of pollution in a year, which amounts to 160 to 240 tons of pollution over the life of an engine.
To address the need for cleaner diesel vehicles, EPA created the Voluntary Diesel Retrofit Program to match fleet operators, engine manufacturers, local governments with those who can provide the appropriate technology and resources in cleaning up dirty trucks, buses and construction equipment.
The Web site also provides information to help manufacturers have their retrofit technologies verified by EPA for appropriate use, and shows state officials how to incorporate diesel retrofits into their air quality plans. EPA has already obtained commitments from fleet operators to retrofit more than 5,000 diesel vehicles. EPA will address emissions from new heavy duty vehicles and engines through a two-part regulatory strategy, beginning with 2004 models.
