MACKINAW CITY, Mich. — Enbridge Inc. said Monday that it retrieved a 45-foot steel rod that was resting against an underwater oil pipeline where lakes Michigan and Huron converge.
The debris had been at the bottom of the Straits of Mackinac since September, when a borehole collapsed during geotechnical work in advance of the construction of a tunnel to surround the Line 5 pipes. Enbridge deployed a remote-operated vehicle to remove the rod on Saturday night, said spokesman Ryan Duffy.
“Favorable weather conditions at the Straits in recent weeks prevented the water from icing over, providing Enbridge a window of opportunity to complete this work,” he said.
The rod had moved from its original position near the pipeline and was found resting on the west leg. It never posed a safety or environmental risk to Line 5, the water or ship traffic, Duffy said.
