(The Center Square) – The U.S. Army Corps of Engineers has determined the Line 5 tunnel project would have a “beneficial cumulative effect” on Michigan and its environment by reducing the risk of an oil leak.

This is according to a recently-released draft environmental impact statement, which examined the pipeline proposal for Line 5. The transmission line owned by Enbridge goes 645 miles from Superior, Wis., through the Straits of Mackinac in Michigan to Sarnia, Ontario.
