Delaware City (AP) — State officials are citing the Delaware City Refinery for violating a 2013 state order that limits where the company can ship crude oil by barge. The Department of Natural Resources and Environmental Control issued a single violation notice to the refinery Friday. Environmentalists hope the citation will help resolve a dispute with refinery owner PBF Energy over where it's permitted to ship its oil. State officials say a 2013 order limited the final destination of barges loaded with crude oil in Delaware City to another PBF Energy refinery in Paulsboro, N. J. Refinery officials claim they can ship crude anywhere in the world. The citation comes a week after the company told state officials about two 2014 shipments to another location.
