Line 5

Enbridge Energy makes the next move in the legal tussle to stop Michigan from shutting down Line 5.

Governor Gretchen Whitmer has dropped a federal lawsuit seeking to shut down Enbridge’s Line 5 oil and natural gas liquids pipeline.

Despite describing an incursion on its Line 5 oil pipeline last month as “dangerous” and “criminal,” the pipeline operator Enbridge Energy did not file a report to the federal agency that tracks pipeline safety problems.

Michigan Governor Gretchen Whitmer ordered Line 5 closed a year ago, citing safety concerns. The Biden administration is now involved. But chances of an imminent shutdown appear slim. We lay out some of the hurdles.

A federal judge says a dispute over a Canadian oil pipeline that runs through a section of the Great Lakes belongs in her court.

The Biden Administration is now indicating it has no plans to shut down Line 5, after Canada invoked a dispute resolution provision of a 1977 pipeline treaty that forces negotiations between the countries. Enbridge is battling the state of Michigan's effort to shut the pipeline down.

Enbridge says it temporarily shut down part of its Line 5 Tuesday after protesters tampered with its safety valve equipment near Vassar, Michigan.

Indigenous communities in Michigan say if the United States is going to negotiate with Canada over the Line 5 oil pipeline in the Straits of Mackinac, tribal representatives should be invited too.

Canada officially invokes 1977 treaty agreement on pipelines.

Canada informed a judge that it is invoking a 1977 treaty with the United States. That step should suspend a lawsuit by Michigan to shut down the pipeline.
