MANDAN, N.D. (AP) - A spokesman for North Dakota's only oil refinery says it is running at full capacity to help ease shortages at pipeline terminals in the region.

"We're selling as much as we can," Leif Peterson, a spokesman for the Tesoro refinery in Mandan, said Monday. "We take care of our Tesoro-branded dealers and jobbers first. The people who are not, are on allocations."

The Mandan refinery processes 59,000 barrels of crude oil per day, Peterson said. He did not know Monday how much of that was unallocated.

Gov. John Hoeven and petroleum marketers said last week that refinery slowdowns elsewhere in the region were forcing truckers to wait longer at pipeline terminals to get fuel, threatening to leave service stations short of gasoline during the Fourth of July holiday. Hoeven issued an executive order to waive the limit on how long drivers who are hauling fuel can be on the job.

"We think it's a short-term situation," Peterson said Monday.

Truckers call around and see where they can fined gasoline. "If there's product available, they'll drive to those terminals," he said.

Mike Rud, the president of the North Dakota Petroleum Marketers Association, said Fargo's Magellan pipeline terminal is out until Thursday and the Grand Forks terminal is out until next week. The bottleneck is due to various refinery problems, ranging from maintenance to a fire and flooding, he said.

In Kansas, the Coffeyville Resources refinery was shutting down due to flooding when more than 42,000 gallons of crude oil spilled Sunday, authorities said. Rud said that refinery turns out about 100,000 barrels per day.

"It's just that time of year that if you go down, you just don't catch up because the demand is so high," Rud said.

The impact on prices was unclear. Nationwide, oil prices fell Monday as investors sold to lock in profits from a rally that drove prices above $70 a barrel last week. Gasoline futures also fell as traders anticipated an increase in gas inventories in a government report Thursday.
