The Wisconsin Department of Natural Resources (DNR) has granted a waterway and wetlands permit to Enbridge Energy for their Line 3 replacement project, which will replace a 14-mile section of a pipeline that has been in operation since the 1960s.
The current pipeline has been in operation at reduced capacity because of anomalies found during integrity tests. The new line will be 36 inches in diameter and carry up to 760,000 barrels per day.
In the permit given by the DNR, the pipeline company is required to have an independent consultant oversee that the construction and operation of the line meet state compliance standards as well as minimize negative impacts on the environment.
Enbridge is reviewing the permit and final environmental impact statement from the state and does not yet have a date for the start of construction.
The construction timeline also depends on a permit from the U.S. Army Corps of Engineers who said could take up to a month to review whether they will issue a permit for the project.
