As part of the S15 (ULSD) regulation, the EPA requires that new labels be placed on every diesel dispenser in the United States, excluding California. The label should be located near the indicator that shows how many gallons you have pumped into your diesel vehicle.
If the diesel fuel is S15 (ULSD) then the label will be titled
"Ultra Low Sulfur Highway Diesel Fuel". If the diesel fuel is S500 (LSD) then the label will be titled
"Low Sulfur Highway Diesel Fuel". All Chevron and Texaco diesel dispensers, excluding those dispensers in California, were appropriately labeled by June 1, 2006.
In California, the state has mandated that ULSD be the only fuel available. Therefore, the EPA has exempted California from labeling dispenser pumps.
