The U.S. Army Corps of Engineers says it’s preparing to decide whether to let Alberta-based Enbridge install supports for its underwater oil pipeline in Michigan’s Straits of Mackinac.
Enbridge disclosed Wednesday that erosion had opened a gap beneath one of two Line 5 pipelines in the channel linking Lakes Huron and Michigan. The gap is about 1.83 metres wider than allowed under a state easement.
The company says the pipe’s integrity isn’t threatened. But it wants to install more than 50 screw anchors for greater stability.
Michigan has granted a permit. Enbridge says it’s been waiting 16 months for the Army Corps to do likewise.
Spokeswoman Lynn Rose said Thursday the Corps recently received information it needed from Enbridge to make a decision, which will come soon.
