On Wednesday, a federal judge decided against Michigan Governor Gretchen Whitmer's request to shut down an old oil pipeline beneath the Great Lakes. Governor Whitmer had ordered the removal of a key easement that allows Enbridge Inc. to operate the Line 5 pipeline, which she fears could lead to a massive oil spill. Judge Robert Jonker ruled that regulation of interstate pipelines is the responsibility of the federal government, contradicting state authority. The 4.5-mile Line 5 pipeline transports crude oil between Superior, Wisconsin, and Sarnia, Ontario. Despite the judge’s ruling, there is ongoing litigation related to the environmental impacts of the pipeline and a separate federal judge’s ruling in Wisconsin regarding other aspects of its operation.
