BISMARCK, N.D. (AP) -- Tesoro says it will ``work tirelessly'' to clean up an area north of Tioga where more than 20,000 barrels of crude spilled from one of the company's pipelines nearly two weeks ago. The Texas-based company says in a statement that the affected portion of the pipeline has been shut down.
CEO Greg Goff says ``protection and care of the environment are fundamental to our core values.'' Tesoro says no water sources have been contaminated, no wildlife has been hurt and no one has been injured. Company officials are investigating what caused the hole in the 6-inch-diameter steel pipeline A farmer harvesting wheat discovered the spill September 29th.
It spread over about seven acres, roughly the size of seven football fields.
