Mandan’s Tesoro refinery has been expanding.
It just finished adding 10,000 barrels per day of gasoline refining capacity – bringing that to 60,000 barrels a day. And next year, the refinery will add another 5000 barrels to its diesel fuel refining capacity.
"As you know, the diesel demand in North Dakota continues to increase," said refinery manager John Berger. "That will give us a little more flexibility to allow us to shift gasoline or diesel production, based on where the market needs are. And of course, right now those needs a primarily around diesel fuels."
