ND Pipeline Breaks, Spews 20,600 Barrels Of Oil

(Continued)

Tesoro Logistics, a subsidiary of the San Antonio, Texas-based company that owns and operates parts of Tesoro’s oil infrastructure, said in a statement that the affected portion of the pipeline has been shut down.

“Protection and care of the environment are fundamental to our core values, and we deeply regret any impact to the landowner,” Tesoro CEO Greg Goff said in a statement. “We will continue to work tirelessly to fully remediate the release area.”

Wayde Schafer, a North Dakota spokesman for the Sierra Club, said the spill is an example of the lack of oversight in a state that has exploded with oil development in recent years.

“We need more inspectors and more transparency,” Schafer said. “Not only is the public not informed, but agencies don’t appear to be aware of what’s going on and that’s not good.”

Jensen said he had harvested most of his wheat prior to the spill. But his land is no longer good for planting.

“We expect not to be able to farm that ground for several years,” he said.

An oil pipeline breach in the late 1980s in the northeast corner of the state was larger than this spill, Roberts said.

The Tesoro spill is four times the size of a pipeline rupture in late March that happened north of Little Rock, Ark. An ExxonMobile pipeline burst March 29 and spilled 5,000 barrels of oil in a Mayflower, Ark., neighborhood, forcing the evacuation of more than 20 homes.

Eric Haugstad, Tesoro’s director of contingency planning and emergency response, said the hole in the 20-year-old pipeline was a quarter-inch in diameter. Tesoro officials were investigating what caused the hole in the 6-inch-diameter steel pipeline that runs underground about 35 miles from Tioga to a rail facility outside of Columbus, near the Canadian border. Roberts said the hole may have been caused by corrosion.

Tesoro owns North Dakota’s only oil refinery, which occupies about 1 1/2 square miles of land overlooking the Missouri River in Mandan. The facility was built in 1954, three years after drillers began pumping oil in North Dakota. Tesoro acquired the refinery from BP in 2001.

Tesoro said that the cleanup cost is estimated at $4 million, and Roberts said state and federal regulators are monitoring the cleanup, the completion of which is not known. Cleanup crews have recovered about 1,285 barrels of oil, officials said. A barrel is 42 gallons.

Crews initially burned oil from the surface but have since dug ditches and recovery wells, Roberts said. Several vacuum trucks have sucked oil from the ditches and wells on the site, he said.

A natural layer of clay more than 40 feet thick underlies the spill site and has “held the oil up” so that it does not spread to underground water sources, Roberts said. The nearest home is about a half-mile from the spill site, he said.

“It is completely contained and under control,” Roberts said. “They got very lucky.”
