The Crude Oil Gathering segment of Tesoro Logistics (TLLP) consists of a 700-mile common carrier pipeline, the High Plains Pipeline, which operates out of the Williston and Bakken areas in North Dakota and Montana. TLLP transports almost all the crude oil processed at its North Dakota refinery via the High Plains Pipeline.[2]

In 2013, part of the High Plains pipeline system spilled more than 20,000 barrels of crude oil into a North Dakota wheat field, the biggest leak in the state since it became a major U.S. producer. The six-inch pipeline was carrying crude oil from the Bakken shale play to the Stampede rail facility outside Columbus, North Dakota. A farmer discovered the leak on September 29 while harvesting wheat on his 1,800-acre farm, about nine miles northeast of Tioga, North Dakota.[3] The cause of the spill was later determined to be corrosion.[4]

The pipeline was expanded in 2015 to 90,000 bpd capacity.[2]
