Philadephia Energy Solutions has built a state-of-the-art crude by rail unloading facility that can handle up to three unit trains. The company's two refineries south of Philadelphia, Point Breeze and Girard Point, are the largest consumers of Bakken crude. Rail receipts of 160,000 barrels arrive on a daily basis.

"Times change and if the better crudes start moving down into the Utica, we can take it by rail. If it`s in the Permian Basin, we can take it by rail," Rinaldi said. "So we`re connected everywhere and we don`t get locked in."

In total, the two refineries can process 330,000 b/d of crude oil.
