Clean Diesel Ahead of Schedule
Federal officials say the nation's retail fuel stations are exceeding guidelines for ultra-low diesel fuel, with 85 percent of stations reporting their stocks meet the new emissions standards.
All the country's highway diesel fuel must meet the ULSD standards by 2010 and the retail stations were to reach 80 percent by the end of this year.
The U.S. Environmental Protection Agency says some stations have not yet labeled pumps correctly to reflect the ULSD for sale.
ULSD has 97 percent less sulfur than diesel fuel had carried and new engines mandated for use starting in 2007 are engineered to burn the fuel more efficiently.
The EPA says annual emission reductions will be equivalent to removing the pollution from more than 90 percent of today's trucks and buses, when the current heavy-duty vehicle fleet has been completely replaced in 2030.
