The North Dakota Pipeline Company (NDPL) system is a 950-mile (1530 km) crude oil pipeline system that collects oil from fields in the Williston Basin in Montana and North Dakota transports it eastward to other pipeline systems that carry oil to refineries in the Midwest.
In addition to collecting oil from wells in the United States, it also connects to a Canadian pipeline system owned by Enbridge at North Dakota's border with Saskatchewan. The American pipeline is owned by Enbridge Energy Partners, LP, an organization partly owned by the Canadian company.
The pipeline's eastern terminus is in Clearbrook, Minnesota where there is a junction with Enbridge's Lakehead System and the Minnesota Pipeline (ultimately owned by Koch Industries).
