For more than six decades, Enbridge’s dual Line 5 pipelines have run four miles along the bottom of the Great Lakes, exposed to the elements. The pipelines carry tars sands crude and natural gas liquids across the Straits of Mackinac, the narrow waterway connecting Lake Michigan and Lake Huron.
The pipelines are moving oil “near delicate wetlands and through fish spawning habitats where swift currents pull water between the Great Lakes,” The Narwhal says. Michigan scientists, conservationists and tribes have been “warning that Enbridge’s Line 5 was a disaster waiting to happen,” the article said.
For more than five decades, the Enbridge Line 3 tar sands pipeline has operated along a 282-mile corridor across northern Minnesota. It passes through sensitive wetlands and wild rice waters, crossing rivers and streams with some of the state’s cleanest waters.
Line 3 is in such bad shape, it can only operate at half capacity. State regulators worry it’s a disaster waiting to happen.
When it comes to addressing Minnesota’s aging Line 3 and Michigan’s aging Line 5, Enbridge offers different interpretations about the state’s role in pipeline safety.
