Located on the South Side of San Antonio, the 14,500-barrel-per-day refinery produces and sells various products, including jet fuels, ultra-low sulfur diesel (ULSD), naphtha, reformates, liquefied petroleum gas (LPG), specialty solvents and other highly specialized fuels, to commercial and retail customers and the U.S. military. The Elmendorf terminal, which is approximately 12 miles away from the refinery, stores the crude oil that is processed at the refinery.To significantly improve efficiency, NuStar built and recently put into service a 12-mile pipeline between the terminal and the refinery that now moves the crude to the refinery. The effort effectively removed approximately 80 crude delivery trucks per day from San Antonio roads. Not only is this pipeline reducing traffic and cutting transportation costs, it also is expected to reduce refinery unplanned outages and increase refinery runs because the crude oil delivered by pipeline has a more consistent quality. To further enhance the safety of refinery employees, the company moved all non-operating personnel out of the refinery and into an 18,000-square-foot office complex at Brooks City Base in San Antonio that includes a state-of-the-art laboratory. In addition to safety and reliability improvements, NuStar also has conducted significant environmental cleanup as well as beautification efforts that benefited the surrounding community.
