Enbridge Energy (Enbridge) is proposing to construct a new oil pipeline in Minnesota to replace its existing Line 3 pipeline. Enbridge is proposing that the new pipeline follow the existing Line 3 pipeline from North Dakota to the Clearbrook Terminal in Clearwater County, Minnesota. From the Clearbrook Terminal eastward, Enbridge proposes that the pipeline be constructed in a new right-of-way, south of the existing Line 3, ending at an existing terminal in Superior, Wisconsin. Enbridge is proposing that the existing Line 3 pipeline be permanently deactivated and remain in place.
Enbridge states that the purpose of the project is to address pipeline integrity and safety concerns related to the existing Line 3 and to restore the throughput of the line to its original operating capacity of 760,000 barrels per day (bpd).
Enbridge has applied for a certificate of need (CN) and a route permit from the Minnesota Public Utilities Commission (Commission) to construct and operate the project. The Commission has authorized the Department of Commerce, in cooperation with the Minnesota Department of Natural Resources and the Minnesota Pollution Control Agency, to prepare an environmental impact statement (EIS) for the project. Following completion of the EIS and public hearings, the Commission will make decisions on Enbridge's CN and route permit applications.
