Company agrees to replace underwater oil pipeline between Great Lakes | TheHill

Enbridge Energy agreed Wednesday to replace a decades-old oil product pipeline under Michigan’s Straits of Mackinac amid fears that it could leak into the Great Lakes.

The Canadian company and Michigan Gov. Rick Snyder (R) announced the deal years after bipartisan concern about Line 5 started to grow. The straits, about 3.5 miles wide, connect lakes Superior and Michigan.

Enbridge will pay $350 million to $500 million to build a tunnel for new pipes 100 feet below the bottom of the straits to replace the current pipes that sit on the seabed with little above them. Construction is estimated to take seven to 10 years, and Enbridge could lease space in the tunnels for other utilities.
