Delaware City Refinery

The Delaware City Refinery, currently owned by Delaware City Refining Corporation, a subsidiary of PBF Energy, is an oil refinery in Delaware City, Delaware. When operational it has a total throughput capacity of 210,000 barrels per day , and employs around 570 individuals.
The refinery was commissioned in 1956 and Getty Oil operated it up until 1984, when Texaco bought Getty. In 1988, Star Enterprises, a company started when Saudi Aramco bought half interest, took over the refinery until 1998, when Motiva Enterprises, a joint venture between Star and Shell, operated it. Motiva's operation was the most controversial, with many lawsuits resulting from an explosion and many federal emission regulations violations. Premcor Refining Group bought the refinery from Motiva in 2004, but Valero acquired Premcor a year later.
