Calumet Specialty opens massive refinery in North Dakota

Indianapolis-based Calumet Specialty Products Partners LP and its partner have opened a $430 million oil refinery in western North Dakota.

Calumet built the Dakota Prairie Refinery near Dickinson as part of a joint venture with Bismarck-based energy company MDU Resources Group. It is the first greenfield fuels refinery to open in the United States in nearly 40 years.

Officials said Monday that it has begun producing diesel fuel and is expected to start selling it later this month.

Crews broke ground on the refinery in March 2013 at a 318-acre site. Once it is fully operational, it will process 20,000 barrels of oil each day into diesel fuel and other products. A barrel is 42 gallons.

About 80 people work at the plant.

The only other refinery producing fuel in North Dakota is the Tesoro Corp. plant at Mandan.

Calumet Specialty shares were down 1.9 percent near middday Monday, to $26.90, but are up almost 20 percent since the beginning of the year.
