The Line 3 Replacement Project
Enbridge Energy, Limited Partnership’s (Enbridge) Line 3 Replacement Project (also known as Line 93) is a 330-mile long 36-inch diameter crude oil pipeline that replaced 282 miles of the former 34-inch Line 3 pipeline in Minnesota.
The Line 3/93 pipeline originates at Enbridge’s Edmonton Terminal near Edmonton, Alberta, Canada and ends at Enbridge’s Superior Terminal near Superior, Wisconsin. In Minnesota, the route of the pipeline follows the Enbridge Mainline System corridor from the North Dakota border in Kittson County to the Enbridge’s Clearbrook Terminal Facility in Clearwater County. From the Clearbrook Terminal, the pipeline diverges from the Enbridge Mainline System and generally follows an existing pipeline right-of-way south through Hubbard County eventually turning east and following portions of existing transmission and transportation rights-of-way before rejoining the Enbridge Mainline System corridor in St. Louis County and continuing to the Wisconsin border.
The Line 3/93 pipeline has an annual average capacity of 760,000 barrels per day (bpd) and transports a mix of light, medium, and select heavy crude oil (crude). Operationally, the Line 3/93 pipeline transports crude from Canada to the Enbridge Terminal Facility in Clearbrook for subsequent delivery to Minnesota refineries via interconnected pipelines operated by the Minnesota Pipeline Company, and to the Superior, Wisconsin terminal for subsequent delivery on the Enbridge Mainline System to refineries in the Midwest, Eastern Canada, and the Gulf Coast.
