Superior Terminal



Enbridge’s Superior Terminal, built in 1950, has come a long, long way in 70 years. The 550-acre terminal has become a crucial hub for safe, reliable crude oil distribution across the United States. About 20% of all daily U.S. crude imports pass through the facility, which has a shell capacity of 13 million barrels.

Superior Terminal serves as a control point and hub facility for crude oil products. Enbridge transports and temporarily stores these products en route to their refining destination. This facility serves 10 pipelines—five inbound lines, four outbound lines and one line that passes through the terminal moving diluent from Illinois to Edmonton, Alberta.

Safe and reliable operations are the foundation of Enbridge’s business. We focus heavily on prevention work—including regular inspections, 24/7 monitoring of all our pipeline systems, and a robust maintenance program—to keep our pipelines and facilities healthy and fit for service.
