Enbridge says a test over the weekend of the line that runs under the west bay of the Straits of Mackinac showed no signs of leaks or breaks. Enbridge ran a successful test of the east line earlier this month.
John Gauderman is with Enbridge.
“Our job continues to be ensuring the safety and reliability of Line 5 through the straits, as well as our entire system in every community through which it traverses," said Gauderman.
The pressure test on Line 5 is part of a court settlement following the Kalamazoo River spill seven years ago.
