San Antonio-Valero LP, the owner of a 2,000 mile anhydrous ammonia pipeline through the Midwest, and its general partner, Valero GP Holdings LLC, will change their names to NuStar Energy LP and NuStar GP Holdings LLC, respectively, as a result of the separation from Valero Energy Corp. The NuStar name and blue-and-yellow logo, which features a shooting star, will begin being used externally on April 2, 2007. The introduction will coincide with the launch of the newly rebranded web sites and the first day that both companies’ units begin trading under new ticker symbols – NS for NuStar Energy. and NGP for NuStar GP Holdings – on the New York Stock Exchange. The name change also dovetails with the LP’s move from Valero Energy’s campus to a new 84,000-square-foot corporate office in north San Antonio.
