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