The Michigan Department of Environmental Quality says Enbridge Energy can install four additional anchor supports on the Line 5 pipeline that runs beneath the Straits of Mackinac.
The MDEQ issued a permit for the four supports to maintain the integrity and safety of the pipeline.
Enbridge still needs a permit from the U.S. Army Corps of Engineers.
Enbridge wanted approval to install up to 18 additional supports, but those are still pending after significant public comment and opposition from the Grand Traverse Band of Ottawa and Chippewa Indians.
The tribes and others want a full environmental review before additional permits are approved.
In full disclosure, Enbridge is a financial supporter of this station.
NOTE: An earlier version of this story reported a permit for 18 additional supports had been denied. That permit is still pending. We regret the error.
