Lakehead System

    The 1,900-mile Lakehead System, which is the U.S. portion of the world's longest liquid petroleum pipeline, has operated for more than 60 years and is the primary transporter of crude oil from Western Canada to the United States. The system spans from the international border near Neche, N.D., to the international border near Marysville, Mich., with an extension across the Niagara River into the Buffalo, N.Y., area. It consists of approximately 3,500 miles of pipe with diameters ranging from 12 to 48 inches; 60 pump station locations; and 64 crude oil storage tanks with a capacity of about 11.6 million barrels.

    The Lakehead System serves all the major refining centers in the Great Lakes, Midwest and Ontario, Canada, and through its connection with the affiliated Canadian pipeline, this system has increasing access to refineries in the Mid-Continent and Gulf Coast. Total deliveries on the Lakehead System averaged 1.65 million bpd in 2009, meeting approximately 75 percent of Minnesota refinery capacity; 70 percent of the refinery capacity in the greater Chicago area; and 77 percent of Ontario's refinery demand.
