North Dakota U.S. Senator Heidi Heitkamp said, "As North Dakota continues to be a national leader in energy development, we have to make sure we're not only meeting the energy needs of today but also investing in the future. MDU Resources and Calumet have clearly taken a forward-looking approach by committing to this significant Dakota Prairie refinery project, showing that our state's oil play in the Bakken is not just a short-term boom, but rather a valuable resource for North Dakota for decades to come. Building out our energy infrastructure is one of the most important ways we can help secure North American energy security and independence, and I'll keep working to make sure we invest in a true, all-of-the-above energy strategy."North Dakota U.S. Representative Kevin Cramer said, "Once again North Dakota leads America's energy renaissance with the successful completion of our nation's first new oil refinery in 40 years. I congratulate MDU Resources Group and their partner Calumet Specialty Products Partners for their leadership in capitalizing on increased energy production in North Dakota while providing additional diesel fuel for the region's market. The American 'can-do' attitude and willingness to risk capital for an opportunity to make money continues to make North Dakota a place where dreams can happen. Thank you once again, MDU and Calumet, for your willingness to take a risk in North Dakota." The refinery took approximately 2.5 million man-hours to complete, with more than 800 workers on site during peak construction. Work was completed with an outstanding safety record that included no lost-time accidents. The facility is operating 24 hours a day, seven days a week with about 80 full-time employees. In addition to diesel, the Dakota Prairie refinery is producing up to 6,500 bpd of naphtha, which is used as a diluent to transport heavy oil by pipeline and as a feedstock in gasoline, and 6,000 bpd of atmospheric tower bottoms, which can be used as a feedstock for lubricating oils and other refined products.
