“There is a pipeline that‘s sitting at the bottom of the Straits of Mackinac. It was designed for a 50 year life and it’s been down there for 63 years. There’s a risk involved in this.”

In Line 5 puts Great Lakes at risk on Absolute Michigan via the University of Michigan (video below):
Up to 152 miles (245 km) of coastline in lakes Huron and Michigan could be fouled by a single oil spill at the straits, according to the simulations. When all 840 simulated spills are plotted on a map, a total of 720 miles (1,162 km) of shoreline in the U.S. and Canada are considered potentially vulnerable to spills that would require cleanup. Seven hundred twenty miles is roughly the distance from Detroit to Atlanta.
Areas at highest risk include Mackinac and Bois Blanc islands, as well as locations directly east and west of Mackinaw City. Communities also at risk include Beaver Island, Cross Village, Harbor Springs, Cheboygan and other places along the lakes Huron-Michigan shoreline.
…”Until now, no one knew exactly how much shoreline was vulnerable to spills in the Straits of Mackinac,” said Schwab, a research scientist at the U-M Water Center. “These findings show that under the right conditions, a spill in the Straits of Mackinac could affect a significant amount of shoreline and open-water areas in either Lake Michigan or Lake Huron, or both, very quickly.”
