A portion of Enbridge's Line 5 oil and gas liquids pipeline, a 6.4-km segment dividing into two pipes lying on the bottom of the Straits of Mackinac, connecting Lake Huron and Lake Michigan between Michigan's Upper and Lower peninsulas, has been temporarily shut down pending a hearing on its safety scheduled for next Tuesday.
Ingham County Judge James Jamo approved a temporary restraining order saying Enbridge has not provided enough information to show that continued operation of the west leg of its Line 5 twin pipeline is safe.
Enbridge last week said an anchor support on the east leg of the pipeline had shifted. The company said Line 5 itself was not damaged and that no oil spilled into the water.
Attorney General Dana Nessel petitioned the court on Monday to shut down the pipeline after Enbridge announced it has resumed flows on the west leg.
“With the continued operation of this pipeline, the risk of severe and lasting environmental damage to Michigan’s most important natural resource continues to grow every day,” Nessel said.
