FLOW’s Technical Questions for the Mackinac Straits Corridor Authority

The Mackinac Straits Corridor Authority (MSCA) is a three-member panel that is responsible for overseeing Enbridge’s proposed pipeline tunnel project under the busy, environmentally sensitive Straits of Mackinac, pending all applicable permits and approvals.

In June 2023, FLOW submitted public comments to the MSCA, to help further public understanding of the purpose, need, and challenges associated with the present status of the tunnel project. For each question, FLOW has provided background information in order to contextualize the questions and illustrate the importance of providing critical project information so that stakeholders can be better informed.

The next meeting of the MSCA will be held on October 2, 2023 in St. Ignace.

FLOW Urges Mackinac Straits Corridor Authority to Halt Action on Unauthorized ‘Line 5’ Oil Tunnel

Proposed project Fails to Comply with Great Lakes Submerged Lands Act and Public Trust Law


FLOW, an independent Great Lakes law and policy center based in Traverse City, Michigan, filed formal comments today with the Mackinac Straits Corridor Authority, calling on the body to halt any further implementation of Enbridge Energy’s proposed Line 5 oil pipeline tunnel until the authorizations and approvals required by public trust common law and statute have been applied for and obtained.

The Corridor Authority, which is housed in the Michigan Department of Transportation, will meet Friday, March 6, at 10 a.m. in St. Ignace to discuss past and ongoing planning for the location and construction of the oil tunnel and new pipeline in the state public trust soils beneath the waters of the Great Lakes—the Straits of Mackinac.

The Mackinac Straits Corridor Authority and Enbridge have not applied for, nor received, the required legal authorization from the Michigan Department of Environment, Great Lakes, and Energy to proceed with the oil pipeline tunnel. Canadian-based Enbridge hatched the tunnel scheme with the former Snyder administration to replace the 67-year-old decaying Line 5 pipelines in the open waters of the Straits of Mackinac, where Lake Michigan meets Lake Huron.

“The oil tunnel negotiators and parties’ attempt to bypass the Great Lakes Submerged Lands Act (GLSLA) and the public trust law constitute one of the most egregious attacks on citizens’ rights and sovereign public trust interests in the Great Lakes in the history of the State of Michigan,” said FLOW Founder and President Jim Olson.

“The Mackinac Straits Corridor Authority must understand that it is subject to the public trust doctrine and law that applies to the Great Lakes and the soils under them,” said Olson, a water law and environmental attorney. “When Michigan joined the United States in 1837, it took title as sovereign for its citizens under the ‘equal footing’ doctrine to all of the navigable waters in its territory, including the Great Lakes, and ‘all of the soils under them’ below the natural ordinary high-water mark. These waters and the soils beneath them are held in, and protected by, a public trust.”

The public trust doctrine means that the state holds these waters and soils beneath them in trust for the public for the protection of preferred or dedicated public trust uses of navigation, fishing, boating, swimming, bathing, drinking water, and other recreation. There can be no disposition, transfer, conveyance, occupancy or use of any kind of these public trust waters and the soils beneath them, unless there is a statute or law that expressly authorizes that action.

The State and Enbridge must first obtain authorization under the GLSLA for the public-private partnership to establish a long-term agreement for the 99-year lease and occupancy agreement for a tunnel or pipeline in or through the soils and bottomlands of the Straits of Mackinac.

FLOW, as well as a coalition of state-wide public interest organization making up the Oil & Water Don’t Mix campaign, contends that boring an oil tunnel in and through the soils for an oil tunnel is not only subject to these public trust laws, but that crude oil pipelines in the or under the Great Lakes are not a solution given the risks and threats to the Great Lakes, its people, businesses, and communities. FLOW, OWDM, and other communities and organizations have also called for the shutdown of the 67-year old existing line 5 because of the immediate threat to the Straits and the risks posed by the pipeline’s more than 400 stream and river crossings in the Upper and Lower Peninsulas. Enbridge’s proposal to allow electrical lines and other infrastructure to occupy the proposed oil pipeline tunnel is a bad idea that poses an explosion risk. There is adequate capacity in the thousands of miles of the Enbridge crude oil pipeline system to meet its needs for Michigan and Canada without the perilous existing Line 5 or crude oil tunnel for another 67 years.

FLOW Supports Gov. Whitmer’s Request for a ‘Line 5’ Opinion from Attorney General

FLOW Supports Gov. Whitmer’s Request for an Opinion from Attorney General on Legality of Hastily Crafted Law and Side Agreements on ‘Line 5’ Oil Pipelines and Proposed Tunnel in Mackinac Straits


The following statement can be attributed to Jim Olson, environmental attorney, founder, and president of FLOW (For Love of Water), a Great Lakes law and policy center based in Traverse City:

“This first and immediate step by Gov. Gretchen Whitmer in a letter asking Attorney General Dana Nessel for an opinion on Public Act 359 is critical in unpacking the layers of problems with the newly enacted law, any tunnel agreement, and most importantly the massive threat posed by the existing Line 5 in the Straits of Mackinac, a threat that must be ended in a swift and orderly fashion based on the rule of law under our state constitution, statutes, and the public trust doctrine in the Great Lakes.”

“In the last three weeks of 2018, then-Gov. Rick Snyder, the Department of Environmental Quality, and Department of Natural Resources signed agreements to enable Enbridge to construct a tunnel that the state would own and lease to Enbridge for 99 years for a new crude oil pipeline under the waters and in the soils of the bottomlands of the Straits of Mackinac. In order to finalize the deal before the end of the year, the Republican-controlled legislature during the lame-duck session rushed through a law—Public Act 359—that set up a Mackinac Straits Corridor Authority to sign the tunnel deal with Enbridge and guarantee the transfer of publicly owned and controlled Great Lakes bottomlands and other financial benefits to Enbridge for private gain, the 99-year privately owned pipeline.

“During this same time, Governor Snyder, the DEQ, DNR, and Enbridge without public review finalized a separate agreement that would give Enbridge the right to continue using its existing dangerous and flawed Line 5 pipelines in the open waters of the Mackinac Straits for another 10 years, or as long as it takes to complete the tunnel and install the new pipeline.

“Everyone agrees that the release of oil to the Great Lakes would cause massive harm to those waters, as well as businesses, communities, property owners, tribal fishing rights, and the public’s paramount rights for fishing, boating, and recreation protected by the public trust doctrine – an ancient principle that prohibits the transfer of public lands and waters without compliance with laws that assure a public purpose and no imprudent risks to health, environment, and property.

“Public Act 359, coupled with the State’s public entanglement with Enbridge, puts private gain and economic interests above the State’s and public’s paramount trust interest in the waters and soils of the Great Lakes.  The law and entangled state and Enbridge agreements represent one of the largest, if not largest, threats in the state’s history to the state’s ownership and public trust duty to protect the public’s rights and uses from private takeover or harm to the Great Lakes. Act 359 and these agreements for a tunnel and continued use of the existing, flawed Line 5 were not authorized under the standards of public trust law; the state and Enbridge flouted the Great Lakes Submerged Lands Act that requires transfers and agreements for occupancy of the soils of under the Great Lakes by trying to avoid and ignore this most basic law and public trust principles.

“Public Act 359 and the agreements are peppered with other serious problems, most of which are covered by the questions the Governor has asked the Attorney General to answer.  These include:

  • Adding the tunnel and corridor authority to the 1952 law that created the Mackinac Bridge Authority goes far beyond the original public purpose to build a public bridge;
  • Establishing a term for members of the board of the corridor authority that exceeds the 4-year limit under Article III of the Michigan Constitution;
  • Violating provisions of the state constitution that prohibit fostering private or special purposes, the comingling of the government to aid primarily private projects, the appropriation of public property for private purposes, and the entanglement of the credit and taxpayers of the State for primarily private purposes.

“We hope this critical first step by the Governor and Attorney General will be followed by an immediate and full review of the Snyder administration’s and agencies’ mishandling of the grave and continuing risks of the existing Line 5, and the real and imminent threat to the Mackinac Straits, towns and cities like Mackinac Island, tribal fishing interests, private property interests, businesses, and the rights of the public in the Great Lakes.”
