Enbridge Inc. says it will restart the east segment of Line 5 in the Straits of Mackinac after winning approval from the U.S. Pipeline and Hazardous Materials Safety Administration and the Michigan Circuit Court.
The Calgary-based company shut down both legs of the pipeline in June after noticing a disturbance to an underwater anchor supporting the eastern line.
The west leg was restarted, then ordered shut down by a judge at the request of Michigan state Attorney General Dana Nessel, then started again, but the east leg has remained closed.
Line 5 moves crude oil and propane from Wisconsin to Sarnia, Ont., passing through parts of Michigan’s upper and lower peninsulas. A 6.4-kilometre-long segment divides into two pipes that cross the bottom of the Straits of Mackinac, which connects Great Lakes Huron and Michigan.
Vern Yu, Enbridge vice-president of liquids pipelines, says the decision to allow the restart is good news for Michigan residents who depend on the energy Line 5 delivers.
Enbridge says it has been assured by the pipeline administration that there are no integrity issues with Line 5.
