The Mandan Refinery began operations in 1954 and today has a capacity of 74,000 barrels per day (bpd) primarily processing sweet (low sulfur) domestic crude oil from North Dakota. Situated on 960 acres of land, the refinery dedicates 640 acres to wastewater treatment and wildlife management through a wetlands project known as the North 40.

 

In addition to employing 250 full time employees with an emphasis on process safety, Andeavor makes an effort to support the Mandan community through grants to charitable and non-profit organizations in the Northern Great Plains. In addition, Andeavor awarded a three-year, $750,000 grant to Bismarck State College to develop a virtual process technology training program and completed a two-year, $250,000 grant to the North Dakota Safety Council to develop a state-of-the-art training center.

 

The facility manufactures gasoline, diesel fuel, jet fuel, heavy fuel oils and liquefied petroleum gas. Refined products are trucked and railed from Mandan and shipped east via pipeline to supply the Jamestown area, eastern North Dakota and Minnesota. Currently, over 95% of the crude oil processed at the refinery is from the Williston Basin Bakken formation and the remainder is from traditional Williston Basin light sweet crude oil production.

Health & Safety at Andeavor

Safety is and always will be a Core Value at Andeavor. Recognized for excellence in safety performance by OSHA in 2014, the following year the refinery logged 3.8 million hours without a Days Away From Work injury. Andeavor continues to strive to achieve our ultimate goal of an incident-free workplace by, in part, instilling a culture of personal responsibility among our employees and contractors.

 

We are committed to operating our refineries, pipelines, retail stations and other facilities in a manner that promotes the health and safety of our employees, our customers and the communities where we do business. In addition to general safe working practices, our employees receive training in the safe handling and use of refinery chemicals, hazardous wastes and other hazardous materials; emergency response tactics, including firefighting procedures; and the use of emergency response and personal protective equipment.
