Whitmer rethinks Line 5 tunnel permits, ramps up shutdown pleas after court ruling

Michigan's top environmental officials are reevaluating permits for the proposed Line 5 tunnel project, following a recent Michigan Supreme Court decision that imposed stricter environmental review standards. Governor Gretchen Whitmer, alongside Michigan Department of Environment, Great Lakes and Energy Director Phil Roos, announced the development on Wednesday, describing the pipeline as "a ticking time bomb in the heart of the Great Lakes."

Whitmer also wrote a letter urging outgoing Enbridge CEO Gregory Ebel to decommission the pipeline within months, stating that the Michigan Supreme Court has mandated a more thorough examination of the tunnel's environmental consequences and alternatives.

Environmentalists and Native American tribes, who oppose the pipeline, welcomed the renewed permit scrutiny and shutdown push as a victory for the Great Lakes. Conversely, unions and business organizations that back the tunnel criticized the announcement as a setback. Enbridge spokesperson Ryan Duffy expressed disappointment over the added delay for a project originally targeted for completion in 2024, while pledging to work with the governor to safeguard Michigan's natural resources and maintain the safe operation of essential energy infrastructure.

Tensions have escalated in recent weeks following a series of related decisions. On July 15, the state's Department of Environment, Great Lakes and Energy issued crucial permits for the tunnel project, which angered opponents of the pipeline. Two weeks later, on July 31, the Michigan Supreme Court overturned a separate tunnel permit issued by the Michigan Public Service Commission, ruling that the commission had not adequately evaluated environmental impacts or explored alternatives to building the tunnel.

The ruling could add years to the tunnel project's timeline and set a precedent for future state environmental reviews, necessitating comprehensive assessments of the potential effects on natural resources and the public's access to the Great Lakes.

Opponents of the tunnel contend that the EGLE permit is vulnerable to closer scrutiny. Bay Mills Indian Community, represented by an Earthjustice lawyer, plans to appeal the permit. Similarly, supporters of the tunnel project argue that it is necessary to protect the Great Lakes, maintain energy access, and create construction jobs.

Whitmer's and Roos's announcement, however, does not terminate the EGLE permit. Instead, Roos noted that conditions imposed on the permit delay construction until legal questions are resolved. In her letter to Enbridge outgoing CEO Gregory Ebel, Whitmer questioned the feasibility of the tunnel's construction and urged Ebel to seek an alternative method for transporting Enbridge's petroleum that does not rely on Line 5.
