The U.S. Environmental Protection Agency (EPA) is now requiring refiners and fuel importers to cut the sulfur content of highway diesel fuel 97%.
At a demonstration held at a southern California truck stop, members of the EPA were joined by representatives from California Air Resources Board, Western States Petroleum Association and International Truck and Engine Corporation to announce the new fuel.
Ultra low sulfur diesel fuel enables advanced pollution control technology for trucks and buses. Consumers will be able to purchase ultra low sulfur diesel fuel and vehicles with clean diesel technology later this year, which will produce the clean air equivalent of eliminating air pollution from 90% of today's trucks and buses.
For California, implementation of ultra low sulfur highway diesel fuel will be complete this fall and nationally, by late 2007.
