BISMARCK, N.D. (AP) — North Dakota’s only oil refinery is planning a monthlong shutdown for maintenance and upgrades beginning next month.
Officials say the planned $125 million project at Tesoro Petroleum Corp.’s Mandan refinery is the most extensive overhaul at the facility since 2003.
The refinery was built in 1954 and produces gasoline, diesel, jet fuel, propane, butane and residual fuel. It also has an ethanol blending facility.
Tesoro acquired the refinery from BP in 2001. The company says the planned overhaul will bring to $250 million the amount it has spent on environmental and production upgrades at the refinery.
