Enbridge took immediate action after learning of the damage to ATC’s cables in the Straits of Mackinac, an incident which is under investigation by the U.S. Coast Guard.

Following a series of inspections of Line 5 in recent days, we have confirmed dents to both the East and West segments of Line 5. There are two dents in the West pipeline and one in the East pipeline.

A review of all leak detection systems and available data indicates that the structural integrity of the pipelines has not been compromised.

We are working closely with the State, the Coast Guard and PHMSA to provide updates on our inspections and our plans moving forward.

We are taking immediate action to assess appropriate, reinforcing repairs.

Going forward, as part of our agreement with the State of Michigan we are exploring new technologies and other means that will help ensure the safety of Line 5.
