Line 3 Pipeline Replacement Project

Image

Project Summary

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 restore 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.

Key Project Documents

This map depicts the pipeline alternatives being evaluated in the environmental impact statement for the Line 3 project. Users can move to different parts of the map by clicking and dragging the cursor to a new location. Users can zoom in and out using the scroll wheel of their mouse or by clicking on the plus or minus buttons is the viewer toolbox.

The map includes several data layers depicting resources that could be impacted by the project. These data layers can be turned on and off by clicking the box next the data layer name. The data layers extend for 10 miles on either side of an alternative. Some layers are visible at a small map scale (zoomed out). Other map layers are only visible at a large map scale (zoomed in). If you click to view a data layer and do not see the layer depicted, zoom in or out until it appears.

Environmental Review and Permitting Process

Enbridge's proposed Line 3 replacement project requires two approvals from the Minnesota Public Utilities Commission (Commission) - a certificate of need (CN) and a route permit.  Enbridge applied to the Commission for these approvals in April 2015. 

The Minnesota Environmental Policy Act (MEPA) requires that an environmental impact statement (EIS) be prepared for major governmental actions that have the potential for creating significant environmental impacts.  To fulfill its MEPA responsibilities, the Commission has authorized the preparation of an EIS that addresses Enbridge's CN and route permit applications.  The Commission has authorized Commerce's Energy Environmental Review and Analysis (EERA) staff to prepare the EIS, in cooperation with the Minnesota Department of Natural Resources and the Minnesota Pollution Control Agency.

The EIS will be issued in draft form, a draft EIS, so that it can be improved through public comment.  A final EIS will be developed based on comments received on the draft EIS.

Upon completion of the final EIS, public hearings will be held in the project area. The hearings will be presided over by an administrative law judge (ALJ) from the Office of Administrative Hearings.  The hearings will address Enbridge's CN and route permit applications.  At the public hearings, citizens will have an opportunity to submit comments, present evidence, and ask questions.  After completion of the hearings, the ALJ will submit a report to the Commission with findings of facts, conclusions of law, and recommendations regarding a CN and route permit for the project.  Decisions by the Commission on Enbridge's CN and route permit applications are anticipated in the spring of 2018.
