Valero Energy Corporation has forged an agreement with Silver Eagle Distributors, the nation's second-largest distributor of Anheuser-Busch products to supply approximately 300,000 gallons annually of its Ultra Low Sulfur Diesel (ULSD) to the Houston-based company. John Nau, president and CEO of Sliver Eagle Distributors, says using the fuel in 42 fleet trucks equipped with emission reduction equipment, the company expects to reduce 8.7 tons of nitrogen oxides (NOx) emissions this year. Nau says the company anticipates using ULSD fuel in the remainder of the fleet that is currently awaiting equipment conversion. Valero Energy Corporation is the first refiner in the Southwest to introduce Ultra Low Sulfur Diesel (ULSD), a specially refined diesel fuel that has significantly lower sulfur content than regular on-road diesel. The comopany introduced its ULSD as part of its fuel program to help improve the air quality in cities that are currently in non-attainment or near non-attainment status for NOx emissions.
