After having been shut down for more than a year, the Delaware City Refinery in Delaware is once again refining crude oil. PBF Energy Co. purchased the idle 190,000-barrel-per-day refinery, an associated terminal and pipeline as well as a powerplant complex in June 2010 from Texas-based Valero Energy for $220 million. It hired Nooter Construction of Philadelphia to upgrade the refinery's fluid catalytic cracking unit.
