Mandan Refinery

The Standard Oil Company, builder of the 29,000 barrels per day refinery held a grand opening on October 2, 1954.

[2] A location along the Missouri River was selected because of the large volumes of water needed by the process units and for power generation.

To support an unprecedented demand for distillates in North Dakota's oil patch, a major expansion project was undertaken in 2012 to increase the processing capacity to 68,000 BPD.

[12] A wet scrubber was installed on the CO-fired crude furnace to reduce sulfur dioxide emissions further and eliminate stack particulates in 2015.

Nearly 200 bird species and many types of mammals find food, cover and breeding sites in this wildlife habitat.

The petroleum refinery was designated as a "star" site, the highest level of recognition offered by OSHA's Voluntary Protection Programs.

About the time of North Dakota's surge in oil production when it rose from the 9th ranked producer in 2002 to 2nd highest in 2014,[19] that connection was repurposed.

A dedicated pipe for railroad diesel fuel also exists from the refinery to the BNSF Railway railyard south of downtown Mandan.

Fuel is also distributed by semi-trailer trucks and railroad cars from its corresponding loading racks located on the refinery proper.
