The debate over a new oil tunnel for Enbridge’s Line 5 pipeline landed at Gov. Gretchen Whitmer’s doorstep this week.

On Tuesday, tribal members and environmental advocates delivered letters and handwritten comments to the George W. Romney Building in Lansing. The notes urged Whitmer and EGLE Director Phil Roos to reject the proposal beneath the environmentally sensitive Straits of Mackinac.

This followed a virtual briefing that activists held with EGLE staff that was punctuated by a display of thousands of folded paper fish, a nod to the Great Lakes’ fragile ecosystem.

Enbridge Energy says a concrete-lined tunnel deep beneath the lakebed would minimize spill risks and ensure energy reliability. 

“Enbridge is working with state and federal agencies to study and develop plans that will minimize and mitigate impacts to the natural environment, natural resources, cultural heritage and community priorities,” wrote Enbridge’s Ryan Duffy in a recent statement emailed to WDET.

Duffy said Enbridge “will build the Great Lakes Tunnel safely, in conformity with thorough safety and environmental reviews by permitting agencies.”

Opponents say the plan threatens wetlands, locks Michigan into fossil fuel reliance for decades, increases carbon emissions, and infringes on tribal treaty-protected waters.

Sean McBrearty of Oil and Water Don’t Mix joined Robyn Vincent on The Metro to discuss the coalition’s specific request and the evidence behind its concerns.

The U.S. Supreme Court could decide if a case involving the Line 5 oil pipeline stays in Michigan court or goes back before federal judges.

The case began in 2019 when Michigan Attorney General Dana Nessel sued in state court to partially shut down Line 5. Nessel cited three state laws to make an environmental case for stopping the project.

It then got moved to federal court in 2021 at the request of Enbridge, the Canadian company that operates the pipeline. That request came much later than a 30-day window to do so, partly because Enbridge says it was waiting on the result of a similar lawsuit from Michigan’s governor.

A lower federal court granted an exception to the timeline. The Sixth Circuit Court of Appeals, however, didn’t buy that argument and sent the case back to the 30th Circuit Court in Ingham County where a hearing was held in January.

The Supreme Court, on Enbridge’s appeal, will decide whether there are exceptions to the 30-day period to remove a case to federal court.

Enbridge argues, while the Sixth Circuit took a narrow view of that time frame, other appellate courts have allowed exceptions. It believes the case belongs in federal court because the matter butts up against international treaty law and some federal laws as well.

In a statement, Enbridge spokesperson Ryan Duffy said the company is “encouraged” by the Supreme Court decision Monday to take up the case.

“The District Court cited the important federal issues in this case, including U.S.-Canada Treaty issues, and the fact that litigation of these issues was already pending in another case in federal court. 

However, the Sixth Circuit Court of Appeals reversed, deciding that district courts have no authority to give exceptions to the 30-day time limit.

The Sixth Circuit’s remand decision is in conflict with decisions from two other federal Circuit Courts of Appeals, which both held that there can be exceptions to the 30-day limit. The Supreme Court review will resolve this conflict in the courts of appeals,” Duffy said in an email.

Meanwhile, the Attorney General’s office is maintaining its position.

“The Department’s lawsuit is based on state claims and law, and it belongs before a Michigan court.  We remain undeterred in our commitment to protect the Great Lakes, especially from the devastating catastrophe a potential Line 5 rupture would wreak upon all of Michigan,” a written statement from AG spokesperson Kimberly Bush said.

If the case goes back to federal court, the proceedings that have happened in state court may be moot. Meanwhile, the legal fight between Enbridge and the governor is already playing out in federal court.

All this is happening as Enbridge tries to move forward with a project to build a tunnel around a replacement section of the Line 5 pipeline that runs through the Straits of Mackinac. That project is currently in the permitting process.

Enbridge says the tunnel would make the pipeline safer by protecting it from anchor strikes. Environmental groups are fighting it, saying it could potentially rupture and dump massive amounts of oil into the Great Lakes.
