On September 23, 2020, a small crew headed onto the Straits of Mackinac in fog so thick they couldn’t see the Mackinac Bridge. Using a remote operated vehicle (ROV), the team explored an area just west of Line 5. Their video captured at least one submerged cultural site. This stone circle is consistent with other underwater and terrestrial finds near Grand Traverse Bay, the Alpena-Amberley Ridge in Lake Huron and on Beaver Island.
The ROV and sonar findings seem to show that Line 5 runs through precious, ancient cultural sites. Findings are now being reviewed by an underwater archeologist. Though these sites are now underwater, approximately 9,000 years ago the Great Lakes water levels were much lower, and evidence of human habitation encircles the northern tip of the Michigan mitt.

When side-scan sonar revealed the potential cultural site, the female water protectors reached out to Fred Harrington, Jr. Harrington is a Navy veteran, LTBBOI tribal councilman and citizen, and professor emeritus. He offered to use a community canoe named Jiimaan, which means "they are kissing" in the language of the Anishinaabek (Odawa, Ojibwe, Potawatomi).
Water protectors secured a letter of support from Sault Ste. Marie Tribe of Chippewa Indians for their efforts to get an independent look at Line 5.
Even a small spill would likely impact 37 miles of shoreline. A large one could impact 722 miles of shoreline. This comparison shows 3 different spill scenarios and the ping pong nature of how water acts in the Straits. The Great Lakes supply the water to over 40 million people and are the backbone of Michigan’s tourist economy.
A contractor for the Coast Guard estimates that a clean-up of 30 percent of an oil spill here would be the best case scenario. This assumes there is daylight and waves of less than three feet, and no ice as they are not fully prepared to handle an open water spill when the Straits are iced-over.
As Lester Graham of Michigan Radio recently reported, "Even if you shut the valves on either side, there’s close to 388,000 gallons of oil in each pipeline (of the 2 sections of Line 5 in the Straits). If both pipelines were damaged, you could see an oil spill nearly as big as the Enbridge Line 6B spill in the Kalamazoo River ten years ago. It was one of the biggest inland oil spills in the country."
Michigan Attorney General Dana Nessel has called for the shutdown of Line 5. She has also commented on the UP Energy Task Force report on alternatives to Line 5 for supplying propane to the UP.
Shutting Line 5 down is in Michigan’s best interest. Governor Whitmer campaigned on shutting down Line 5 but has yet to revoke the easement that allows its continued operation.
Comment period on Enbridge tunnel permits ends Oct. 19
Enbridge hopes to replace Line 5 with a tunnel to include a new pipeline under the bottomland of the Straits. Recently the Michigan Department of Environment, Great Lakes and Energy (EGLE) held information meetings and public hearings on Enbridge's permit applications for their tunnel project, which would mean 5 to 10 years of tunnel construction while leaving the ageing Line 5 under the Straits of Mackinac.
A recent message from Andrea Pierce, Little Traverse Bay Bands of Odawa Indians citizen, asked Native and non-Native water protectors to oppose these permit applications -- under Part 303, Wetlands Protection; and Part 325, Great Lakes Submerged Lands, of the Natural Resources and Environmental Protection Act, 1994 PA 451, as amended and the NPDES (National Pollutant Discharge Elimination System) permit application -- by submitting public comments to EGLE by the deadline of 11:59 p.m. (EDT) on Monday, Oct. 19.
"We are asking that everyone contact EGLE, MPSC, your senator, congress representative and house representative to make a public comment asking to stop the Line 5 tunnel," Pierce writes. "Please CC: mpscedockets@michigan.gov cc: governorsoffice@michigan.gov and YOUR State Reps."
