California calls for lower-sulfur fuel starting in 2006

| 8/5/2003

California’s Air Resources Board will require ultra-low-sulfur fuel for diesel-powered vehicles beginning in 2006, the board announced recently.

The new fuel, which will be phased in, will represent a more than 95 percent reduction in the amount of sulfur in diesel, from the current statewide average of 140 PPM (part per million) to less than 15 PPM. Unlike federal fuel standards, which will call for a similar reduction a couple of years down the road, the California reduction will also apply to off-road vehicles.

The staff at the Air Resources Board estimates the new rules will add about 1 cent to 3 cents to the cost of producing a gallon of diesel fuel in California.
