For Love of Water (“FLOW”) submitted legal and technical comments before today’s deadline in response to the U.S. Army Corps of Engineers’ Notice of Intent to Prepare a Draft Environmental Impact Statement for Enbridge’s proposal to bore and blast a 20-foot-in-diameter tunnel under the Straits of Mackinac, just west of the Mackinac Bridge, to house a new Line 5 oil pipeline for another 99 years.

The public can still comment on the proposed oil tunnel in the Great Lakes by 11:59 p.m. EDT today (Oct. 14, 2022) on the Army Corps’ project website.

The public can still comment on the proposed oil tunnel in the Great Lakes by 11:59 p.m. EDT today (Oct. 14, 2022) on the Army Corps’ project website. The Oil & Water Don’t Mix campaign, of which FLOW is a founding steering committee member, also is collecting and forwarding comments to the Army Corps using an email template that suggests key points to make. FLOW’s tunnel comment also provides critical elements to convey.

FLOW urged the Army Corps to broaden the scope of its analysis to ensure that all regional alternatives are fully considered in an effort to meet regional fossil-fuel energy demands, which are forecasted to dwindle in the ongoing transition to clean energy, while maximizing protection of the Great Lakes and combating climate change.

Enbridge’s proposed Line 5 oil tunnel is not a viable alternative given the forecasted dwindling demand for fossil fuels and the need to maximize protection of the Great Lakes and combat climate change.

In FLOW’s view, Enbridge’s proposed Line 5 oil tunnel is not a viable alternative to meet these regional objectives when viewed in light of all relevant facts. FLOW anticipates that the manifold risks of the tunnel proposal will continue to grow as Enbridge begins to fill data gaps related to geologic conditions, construction challenges, and worker safety.

FLOW Raises Concerns about Risk to Great Lakes, Lack of Public Need, and Information Gaps

FLOW’s comments to the Army Corps include an emphasis on the:

  • Line 5 Pipeline Risk—FLOW opposes tethering the shutdown of the existing dual Line 5 pipelines to a tunnel project that will not resolve underlying the environmental and cultural concerns about siting a major oil pipeline in the middle of America’s greatest surface freshwater resource.

  • Lack of Information—The public is deeply concerned about the risk of a catastrophic tunnel explosion, the economic feasibility and environmental impacts of constructing the tunnel, and the long-term climate impacts of the tunnel proposal. The public needs more information than Enbridge has provided to understand the risks and benefits.

The public is deeply concerned about the risk of a catastrophic tunnel explosion, the economic feasibility and environmental impacts of constructing the tunnel, and the long-term climate impacts of the tunnel proposal.

  • Lack of Public Need—As Enbridge implicitly concedes, there is no long-term public need for the proposed tunnel from an energy standpoint, and it would undermine federal greenhouse-gas reduction policies. Enbridge’s own expert has determined that a Line 5 shutdown would have a de minimis impact on fuel prices.
  • Overly Narrow Focus—Regionalizing the Purpose and Need Statement in the Army Corps study is warranted because Enbridge’s 645-mile Line 5 pipeline is almost 70 years old and past the end of its projected operational life. As Line 5 would need a systemic makeover to keep operating for another 99 years, Enbridge’s proposed tunnel should not be segmented and evaluated in isolation from the entire operation.

Line 5 pipeline is almost 70 years old and past the end of its projected operational life.

  • Strong Public Interest in Great Lakes Protection—The Army Corps’ Purpose and Need Statement in the Notice of Intent is also deficient for lack of recognition of the public interest in protecting the Great Lakes in the face of global water shortages, chronic drought in the United States, and other costly impacts from climate change. Protection of the largest and most valuable surface freshwater system in the world is an economic and environmental imperative. The Great Lakes contain 84% of North America’s fresh surface water and are the cultural backbone for eight states, two provinces, and multiple tribes and First Nations.

FLOW cited lack of recognition of the public interest in protecting the Great Lakes in the face of global water shortages, chronic drought in the United States, and other costly impacts from climate change.

Army Corps Should Consider a Range of Reasonable Alternatives

In order to meet the objectives of a Purpose and Need Statement that focuses on the connection between Enbridge’s Superior, Wisconsin, and Sarnia, Ontario, terminals and gives primacy to the public’s interest in maximizing protection of the Great Lakes, the Army Corps should, at a minimum, consider the following alternatives:

  1. An alternative to connect Enbridge’s Superior and Sarnia terminals without crossing the Great Lakes.
  2. An alternative to use existing capacity in other pipelines and, if necessary, other transportations solutions–such as rail and truck transport of natural gas liquids–in lieu of building new pipeline infrastructure.
  3. A tunnel alternative that fully eliminates the risk of oil intrusion into the Straits of Mackinac in the event of an explosion or similar event.
  4. A “no action” alternative.

Protection of the largest and most valuable surface freshwater system in the world is an economic and environmental imperative. The Great Lakes contain 84% of North America’s fresh surface water and are the cultural backbone for eight states, two provinces, and multiple tribes and First Nations.

The Army Corps’ analysis of “energy need” should result in a determination that Enbridge’s proposed tunnel is contrary to the public interest. The confluence of future demand-side constraints, including the electrification of transportation, disinvestment in Albertan oil production, North American and global prohibitions on the sale and use of internal combustion engine vehicles, and governmental efforts aimed at reducing greenhouse gas emissions are accelerating the transition to a global clean energy economy. These forces driving change are being embraced by public and private interests and represent future trends that will bring measurable economic, environmental, and social benefits. The confluence of these market forces militates against future large-scale investment in fossil fuel infrastructure.

Last Call: Army Corps on Oct. 6 to Hold Final ‘Scoping Meeting’ on Proposed Oil Tunnel in Great Lakes

Editor’s note: Learn more about FLOW’s efforts to shut down Line 5 and stop the proposed oil pipeline tunnel on FLOW’s Line 5 program page and new Line 5 fact sheet.


The public will have a last chance on October 6 to comment orally to the leadership and staff of the U.S. Army Corps of Engineers, Detroit District, on the agency’s plans for a study of an oil tunnel proposed under the Great Lakes.

The Army Corps will hold an online meeting from 1-4 p.m. on Thursday to help set the scope of the agency’s environmental impact statement study of a proposal by Enbridge, Inc., of Canada, to build an oil tunnel under the Straits of Mackinac. The tunnel would house Enbridge’s Line 5 oil pipeline, which has leaked dozens of times across Michigan and Wisconsin while carrying oil since 1953 from western Canada primarily to refineries in Sarnia, Ontario. The Army Corps study is expected to continue through at least 2023.

In addition to the Oct. 6 meeting, the public can comment on the study of the tunnel proposal by October 14 by mail or the Army Corps project website. The Oil & Water Don’t Mix campaign, of which FLOW is a founding steering committee member, also is collecting and forwarding comments to the Army Corps using an email template that suggests key points to make. FLOW’s preliminary tunnel comment also provides critical elements to convey.

Many Troubling Aspects of the Tunnel Proposal

Enbridge wants to bore and blast a 20-foot-in-diameter tunnel under the Straits of Mackinac, just west of the Mackinac Bridge, to house a new Line 5 pipeline. The Canadian company’s stated goal is to continue for another 99 years carrying up to 23 million gallons of oil and natural gas liquids a day through Line 5 and State of Michigan public trust bottomlands where Lake Michigan meets Lake Huron, just west of the Mackinac Bridge.

FLOW and our partners have identified critical deficiencies in the project’s construction permit application, its legal authorization, and the review by State of Michigan environmental agencies of expected impacts to wetlands, bottomlands, and surface water, including from the daily discharge of millions of gallons of wastewater during construction. FLOW and our allies have expressed continuing concerns about the impact to the Great Lakes and lack of public necessity for the project, which would worsen climate change by adding greenhouse gas emissions each year equivalent to almost seven new coal-fired power plants or nearly 6 million new cars to the road, according to experts.

Enbridge also lacks adequate liability insurance, according to a report released by the Attorney General Dana Nessel’s office revealing that Enbridge’s subsidiaries, not its parent company, hold Line 5’s 1953 easement and signed the proposed tunnel agreement; the assets of the subsidiaries’ parent Enbridge are inadequate to cover the costs and economic damages in the event of a moderate spill.

At Prior Army Corps Hearing, a Strong Majority Rejected the Proposed Oil Tunnel

The Army Corps already has held a Sept. 1 online comment session to help scope its tunnel study and a Sept. 8 in-person hearing in St. Ignace, where more than 4 out of 5 people who spoke, from among a crowd of hundreds, said that an oil pipeline tunnel proposed under the Great Lakes was a dangerous idea that would rob future generations by threatening the most precious thing on earth—fresh water—and worsening the climate crisis.

Most commenters at the seven-hour, St. Ignace hearing expressed deep concern for the harm that construction or a potential explosion or spill from the operation of an oil pipeline tunnel could have on their children and grandchildren’s future, local residents, the Great Lakes, drinking water, tourist economy, and jobs—as well as tribal rights, tribal member survival, cultural heritage, the fishery, ecology of the Straits of Mackinac, and the climate. (Read FLOW’s coverage here).

FLOW’s Position on the Scope of the Army Corps Tunnel Study

FLOW’s position, as expressed at the hearing in St. Ignace, is that the Army Corps’ environmental study of the tunnel proposal and alternatives must under the law include, at a minimum:

  1. A “no action” alternative that would use existing capacity in other pipelines and, if necessary, other transportations solutions—such as rail and truck transport of natural gas liquids—in lieu of building new pipeline infrastructure.
  2. An alternative to connect Enbridge’s Superior, Wisc., and Sarnia, Ontario, terminals without crossing the Great Lakes. (See FLOW’s fact sheet on alternatives).
  3. A tunnel alternative that fully eliminates the risk of oil intrusion into the Straits in the event of an explosion or similar event.

Army Corps Process to Continue through at Least 2023

Enbridge has applied for a Army Corps permit under the Rivers and Harbors Act of 1899 and the Clean Water Act, seeking federal approval to discharge dredged or fill materials into waters of the United States, as well as the construction of structures or work that may affect navigable waters. The Army Corps also will conduct an ethnographic/traditional cultural landscape study as part of the environmental impact statement under the National Historic Preservation Act. After considering public comment and issuing the draft EIS likely by fall 2023, the Army Corps will seek additional public feedback, release a final study, and then issue a “record of decision” regarding whether to issue, issue with modification, or deny the Department of the Army permit altogether—consistent with the National Environmental Policy Act.

The Army Corps, Detroit District, to date has identified general concerns in the following categories:

  • Potential direct effects to waters of the United States including wetlands; water and sediment quality; aquatic species and fisheries; threatened and endangered species;
  • Archaeological and cultural resources, including the Straits as a Traditional Cultural Landscape; Tribal treaty rights and interests;
  • Recreation and recreational resources; waste management; aesthetics; noise; air quality; climate change, including greenhouse gas emissions and the social cost of greenhouse gasses;
  • Public health and safety during construction and operations; navigation; erosion; invasive species; energy needs; environmental justice; needs and welfare of the people; and cumulative effects.

FLOW’s Legal Team and Allies Helped Spur the Army Corps’ Full Environmental Study

FLOW continues to be deeply engaged in every step of the Army Corps study and committed to shutting down Line 5 and stopping the oil tunnel. FLOW’s legal team and allies helped spur the Army Corps’ full Environmental Study through our legal research, analysis, and comment, including FLOW’s formal legal comments submitted to the agency in July 2020The legal team challenged the proposed tunnel in December 2020 by submitting comprehensive comments to the U.S. Army Corps of Engineers calling for an environmental impact statement on behalf of a dozen organizations: Chippewa Ottawa Resource Authority, Clean Water Action—Michigan, FLOW, Groundwork Center, League of Women Voters of Michigan, Michigan Environmental Council, Michigan League of Conservation Voters, NMEAC, Sierra Club Michigan Chapter, Straits Area Concerned Citizens for Peace, Justice and Environment, Straits of Mackinac Alliance, and TC 350. The comments demonstrated a serious gap in Enbridge’s evaluation of the presence of loose, unconsolidated rock and sediment in the bottom of the Straits of Mackinac that Enbridge has characterized as solid bedrock.

MPSC: Proposed ‘Line 5’ Oil Tunnel in the Straits of Mackinac Must Undergo Full and Vigorous Public Review

FLOW E.D. Liz Kirkwood

The following statement can be attributed to Liz Kirkwood, environmental attorney and executive director of FLOW (For Love of Water), a Great Lakes law and policy center based in Traverse City:

“The Michigan Public Service Commission’s decision today is a big win for all Michigan residents that upholds their public trust rights in the Great Lakes. The MPSC flatly rejected the untenable claim by Enbridge that it had somehow already received approval in 1953, when Line 5 was built in the Straits of Mackinac, for an oil tunnel it is proposing 67 years later in 2020. The 3-0 vote by the MPSC means Enbridge will not be allowed to dodge a full review of their proposed oil pipeline tunnel, including an August 24 public hearing, which is desperately needed in light of the potential impact on the Great Lakes and its regional economy.

“We applaud the MPSC for rejecting Enbridge’s declaratory ruling request, and instead, requiring that Enbridge’s application be reviewed as a contested case with a public hearing under Michigan’s Act 16. Enbridge now has the burden to show a public need for this proposed oil pipeline under the Great Lakes, ensure no harm or pollution to our public trust waters and lands, and fully consider feasible and prudent alternatives to this project. With society’s urgent need to tackle climate change head on and ensure freshwater security, Enbridge cannot show that its proposed fossil fuel infrastructure is a credible solution for Michigan’s 21st century just and equitable future.”

Can the Mackinac Bridge be used to support the pipelines?

By Gary Street,

Chemical Engineer & FLOW Consultant

 

What if the two twenty inch diameter pipelines that cross the Straits (part of Enbridge Line 5) were hung from the Mackinac Bridge, rather than immersed in water in nearly 300 feet deep? The engineers on the staff at FLOW took a look at the concept. Is it possible? Does it make the situation less environmentally hazardous? What impact will it have on the Bridge? Was the Bridge designed for the extra load?

So we did some calculations.

The result: In addition to the regular car and truck traffic, for which the Bridge was designed, the pipelines would put the added weight of an additional 2000 to 3500 automobiles onto the Bridge. And not just for a short time, but continuously, 24 hours a day, 365 days per year.

Almost certainly the Bridge was not designed for all this extra weight. And what if the lines were to rupture? The oil still goes into the Straits.

Clearly, not a good idea!

Enbridge Operating Line 5 Illegally

Citing new research and documentation revealing cracks, dents, corrosion, and structural defects in the twin oil pipelines in the Mackinac Straits, 22 environmental and tribal groups today formally requested that Gov. Snyder and Attorney General Schuette shut down “Line 5” oil in the Straits based on Enbridge’s multiple easement violations. The violations mean Enbridge is operating illegally and has broken its legal agreement with the state and people of Michigan.

Enbridge’s ongoing violations related to pipeline design threaten the very safety and health of the Great Lakes, and thus trigger the state’s duty to enforce its agreement with Enbridge. Under the 1953 easement, the state must provide Canadian-based energy transporter Enbridge 90 days to resolve any known easement violations.  The state now has substantial legal and factual cause to terminate the agreement with Enbridge to stop the oil flow and protect the Great Lakes, public water supplies, and the Pure Michigan economy, according to an April 13 letter to Snyder and Schuette, signed by partner groups in the Oil & Water Don’t Mix campaign.

“The law and this easement agreement are clear: state leaders cannot wait another year or more while Enbridge continues to violate safety conditions it agreed to and withholds safety inspection and other data from the public and the state,” said environmental attorney Liz  Kirkwood, Executive Director of FLOW (For Love of Water) in Traverse City. “Gov. Snyder and Attorney General Schuette must start the clock to terminate the state’s easement agreement that allows Enbridge to operate the Line 5 pipelines on state-owned bottomlands and waters.”

In their letter, the groups identified eight specific violations of the easement and state law, including:

  • Concealing information about cracks, dents, and corrosion with continued, sweeping assertions and misrepresentations that the Straits pipelines are in “excellent condition, almost as new as when they were built and installed” and have “no observed corrosion.” Of the nine rust spots on the eastern Straits pipeline, corrosion has eaten away 26 percent of the pipeline’s wall thickness in a 7-inch-long area, according to newly released company data.
  • Failing to meet the pipeline wall thickness requirement due to corrosion and manufacturing defects. Newly released Enbridge data reveals that manufacturing defects in the 1950s resulted in pipeline wall thickness of less than half an inch in perhaps hundreds of sections and up to 41 percent less thick than mandated on the west Straits pipeline. Enbridge continues to boast about its “nearly one-inch-thick walls of Line 5’s steel pipe travelling under the Straits.”
  • Failing to meet the “reasonably prudent person” provision by claiming that its steel pipelines lying underwater just west of the Mackinac Bridge since 1953 can last forever and do not require a plan for eventual decommissioning. The 63-year-old pipelines were built to last 50 years.
  • Failing to demonstrate adequate liability insurance, maintain required coating and wood-slat covering to prevent rust and abrasion and adequately support the pipeline, resulting in stressed and deformed segments.
  • Failing to adhere to federal emergency spill response and state environmental protection laws, including Act 10 of P.A. 1953, the Great Lakes Submerged Lands Act (“GLSLA”), the Michigan Environmental Protection Act (“MEPA”), and public trust law.

The twin Enbridge Line 5 oil pipelines lying exposed in the Mackinac Straits, where Lake Michigan and Lake Huron meet, are a high-risk shortcut moving up to 23 million gallons of oil and propane a day primarily from western Canadian oil fields to eastern Canadian refineries, as well as on to Montreal and export markets. FLOW’s research shows there are alternatives to Line 5 that do not threaten the Great Lakes, which hold 20 percent of the world’s fresh surface water, and do not disrupt Michigan’s oil and gas supply.

“Enbridge has consistently failed to provide appropriate documentation to the state and the public that supports its position that Line 5 is fit for service”, said Ed Timm, PhD, PE, a retired chemical engineer and former senior scientist and consultant to Dow Chemical’s Environmental Operations Business, who advises the Oil & Water Don’t Mix campaign. “The historical record and the documentation that Enbridge has provided raise many questions that suggest this unique pipeline no longer conforms to its original design specifications and easement requirements.”

Dozens of local communities and organizations, hundreds of businesses, and thousands of individuals and families support efforts by the Oil & Water Don’t Mix campaign to prevent a catastrophic oil spill by stopping the oil flowing through Line 5 in the Mackinac Straits, which University of Michigan experts have called the “worst possible place for an oil spill in the Great Lakes.” Enbridge has a long history of oil spills from Line 5, which runs from Superior, Wisc., to Sarnia, Ont., and is responsible for 2010’s million-gallon oil spill disaster into the Kalamazoo River that cost $1.2 billion to clean up to the extent possible.

“I think pipelines are the safest way to transport oil, but because of the conditions of the Straits and the age of the pipelines, it is past time for an independent analysis to ensure the safety of this line for the citizens of Michigan,” said James Tamlyn, Chair of the Emmet County Board of Commissioners, which passed a resolution in December calling on the Snyder administration to shut down Line 5 in the Straits of Mackinac. “There’s one thing we all agree on and that’s the importance of protecting our clean water.  It defines us and without it, our communities and businesses would be wiped out.”

To date, more than 30 cities, villages, townships, and counties across Michigan have voted to call on the governor and attorney general to stop the oil flowing through the Straits, including Mackinac Island, Mackinaw City, and the cities of Cheboygan, Petoskey, Charlevoix, and Traverse City. Dramatic new research from the University of Michigan released in late March shows an Enbridge oil pipeline rupture in the Mackinac Straits could impact more than 700 miles of Lake Michigan and Lake Huron coastlines, as well as more than 15% of Lake Michigan’s open water and nearly 60% of Lake Huron’s open water.

“The effects of an oil spill in the Mackinac Straits would have catastrophic consequences for our area and for all Michiganders for years to come,” said Bobie Crongeyer, a community leader with Straits Area Concerned Citizens for Peace, Justice & the Environment, which has advanced resolutions to shut down Line 5 in many communities. “Tourists will find other places to vacation, while we will be left with the devastation that Enbridge leaves behind, including a poisoned fishery and drinking water supplies and a shattered economy.”

The Greatest Threat to the Great Lakes that No One Seems to Know About

The Greatest Threat to the Great Lakes and No One Seems to Know About It: Expanding Enbridge’s Line 5 Through the Straits of Mackinac

Click here to read and download PDF

How often do you hear a story in the news and then feel utterly shocked that you didn’t know anything about it? Well, that’s how all 40 million of us living in the Great Lakes should feel about the Enbridge Line 5 expansion across the Straits of Mackinac—a pipeline expansion project that will transport tar sands oil directly through the heart of the Great Lakes. In a nutshell, this just may be the greatest threat facing the Great Lakes at this time in history. “An oil spill in the Straits of Mackinac isn’t a question of if—it’s a question of when,” according to National Wildlife Federation’s (NWF) comprehensive report on this issue, Sunken Hazard.

What would a tar sands oil spill the size of Exxon-Valdez mean for the Great Lakes? Goodbye fisheries, aquatic food links, goodbye wildlife, goodbye municipal drinking water, goodbye Mackinac Island, goodbye tourism and property values, and goodbye to one of the world’s largest freshwater inland seas.

What company is stealthily completing this hazardous energy venture with limited public scrutiny? Enbridge—the same Canadian company responsible in 2010 for a million gallon tar sands oil pipeline rupture and a $1 billion cleanup along a 35-mile stretch of Michigan’s Kalamazoo River. Known as the largest transporter of crude oil, Enbridge is requesting a permit from the State Department’s U.S. Transportation Department’s Pipeline and Hazardous Materials Safety Administration (PHMSA) to expand its existing pipeline—Line 67 also known as the Alberta Clipper—to transport heavy tar sands oil originating from Alberta, Canada to Superior, Wisconsin. From there, Enbridge, according to company officials, has already expanded the capacity of a second existing pipeline—Line 5—that travels directly through the Straits of Mackinac to a refinery located in Sarnia, Ontario. The 1,000+ mile Alberta Clipper pipeline route will double the tar sands oil that it currently carries and will deliver even more tar sands oil than the highly publicized and controversial TransCanada Corp’s Keystone XL pipeline.

Built sixty years ago in 1953, Line 5’s twin pipelines that cross the Straits of Mackinac—each 20 inches in diameter—were designed to transport light conventional crude oil, not Enbridge’s viscous, heavy tar sands oil or “bitumen” blended or diluted with volatile natural gas liquid condensate, also known as “dilbit.” Dilbit spills are particularly difficult to remediate because the bitumen and diluents separate, releasing toxic volatile organic compounds (VOCs) and heavy, sticky bitumen material. And in Lake Michigan, who knows how long it would take to actually clean up these pollutants. The National Oceanic and Atmospheric Administration (NOAA) estimates that it takes an average of 99 years to rid of pollutants in Lake Michigan.

Now let’s dig a little deeper into Enbridge’s depressing track record. According to NWF, “Enbridge’s pipelines had more than 800 spills in the U.S. and Canada between 1999 and 2010, leaking 6.8 million gallons of oil.” So with the combination of strong currents along the Straits, Enbridge’s inexcusable track record, its weak emergency response, and a strong likelihood of mechanical pipeline failure in this fragile ecosystem, we must ask ourselves: is this a risk we as citizens, inheritors, and future protectors of the Great Lakes are willing to accept?

This Enbridge pipeline expansion is a perfect example of why we have the public trust in our navigable waters—an ancient legal doctrine dating back to the Roman times—designed to protect our common shared resources like the Great Lakes. The public trust empowers us as a democratic and thoughtful people to question the impacts of proposed actions like Enbridge’s and determine whether they will impair, pollute or irreparably harm our water resources, and jeopardize protected water uses like fishing, swimming, and navigation.

This proposed action is a clear violation of the public trust as the pipeline threatens to destroy the Great Lakes’ common waters, which support the region’s $62 billion economy with 1.5 million jobs, drinking water for 40 million citizens, as well as our very social fabric, quality of life and enjoyment, and shared ecosystem with wildlife. The unprecedented scale of such an ecological and economic disaster also would undermine the $1 billion already invested in the U.S. government’s Great Lakes Restoration Initiative. This is why the public trust and its protection of the commons is more important than ever.

What this debate really boils down to is a much-needed larger national conversation about our country’s future energy policy. Not only does President Obama need to have the Keystone XL pipeline on his radar, but all pipeline expansions like this project, in assessing the impacts of climate change. It’s time that our nation makes good energy choices that respect the Great Lakes as a shared common resource protected by the public trust. We need to put the safety of our water and our future generations before our overzealous energy development. If we do this, we can chart a future with clean and abundant water, food, energy and a prosperous economy.

Enbridge Under the Bridge: What We Do and Don’t Know about the Underwater Oil Pipeline in the Great Lakes

FLOW Executive Director Liz Kirkwood

FLOW Executive Director Liz Kirkwood

FLOW and a number of organizations have come together over the last year to rally the public and raise awareness about the Canadian energy company Enbridge and their Line 5 pipeline, a 61-year-old pipeline under the Straits of Mackinac in the Great Lakes which has increased in flow and pipeline pressure and poses a great risk to our common water. On February 5, I carpooled up to St. Ignace, Michigan to attend a public meeting wherein Enbridge delivered a presentation to Mackinac County officials (and a packed room full of concerned citizens) to assuage growing concerns about the Line 5 pipeline expansion. My companions Jim Dulzo from Michigan Land Use Institute, FLOW intern Jonathan Aylward and I didn’t know what to expect, but we certainly all had a lot of questions that remained unanswered.

Background: The issue captured our attention after a critical 2012 report from National Wildlife Federation (NWF) titled Sunken Hazardpublished the scary facts: if Line 5 were to leak, then in the eight minutes that it takes for Enbridge to shut off the pipeline about 1.5 million gallons of oil would release, along with catastrophic impacts and dispersion across both Lakes Michigan and Huron. However, this is not even the “worse case discharge” given that it took the same company, Enbridge, 17 hours to respond to the worse inland oil pipeline spill in U.S. history along the Kalamazoo River just 3 years ago.  In short, the Great Lakes have never been more at risk and yet the public is largely uninformed.

Why FLOW is concerned:

  1. We know that Enbridge has “upgraded” Line 5 with new pump stations but we don’t know for sure what “product” (light or heavy, sweet or sour, dilbit, etc) is being transported 640 miles from Superior, Wisconsin through the Straits of Mackinac to Sarnia, Ontario;
  2. Heavy tar sands is the dirtiest and most carbon-intensive energy on earth and a spill would destroy our shared international waters and way of life;
  3. This “upgraded” pipeline is 61-years-old and is submerged under water in the heart of the Great Lakes that contains 20 percent of the world’s fresh surface water;
  4. Enbridge has a dismal pipeline safety record, underscored by the two recent heavy tar sands disasters in Marshall, Michigan along the Kalamazoo River (1 million gallons spilled in 2010) and Grand Marsh, Wisconsin (50,000 gallons spilled in 2012);
  5. Federal pipeline regulations do not provide for public disclosure in the event of a product change from light crude oil to heavy crude oil for example; and
  6. An unsettling feeling of lack of transparency and public disclosure about the safety of Line 5 for the Great Lakes.

The Enbridge “side of the story”

At 2 pm at Little Bear Arena in St. Ignace, Mackinac County Planning Commission (“the Commission”) Chairman Dean Reid stood before 175 people, amazed at the turnout, and explained the rationale for this special meeting. The fact of the matter was that the Commission “wanted to hear Enbridge’s side of the story” after receiving NWF’s Sunken Hazard, and video footage of the submerged Line 5 under the Straits of Mackinac. Interestingly, though, I learned from Beth Wallace at NWF who co-authored the report that the Commission did not invite NWF to participate as a panelist to publically present both points of view.

Commission officials and the audience listen to the Enbridge representatives' presentation.

Commission officials and the audience listen to the Enbridge representatives’ presentation.

Chairman Reid laid out the agenda, calling for Enbridge to address the integrity of their Line 5 pipeline under the Straits of Mackinac, the frequency of their testing, and emergency procedures in the event of a pipeline rupture. Recognizing the potential regional impact a spill would have in the Straits, the Commission invited other local units of government and organizations to attend this meeting. No public comments were allowed, but Enbridge panelists read and answer cards with written questions.

Next came Enbridge Community Relations Director Jackie Guthrie who described herself as a mom but also as a former lieutenant colonel in the U.S. Army. She gave the audience a succinct and compelling PR presentation on Enbridge’s overall operations. “Think of Enbridge as the ‘Fed-Ex’ of the oil and gas industry,” she cleverly described, “Enbridge delivers 2.5 billion barrels of crude and liquid petroleum, 5 billion cubic/feet of natural gas, and 1,600 MW of renewable energy a day.” Her numbers underscored the amazing recent growth of this billion-dollar company coinciding with North America’s energy boom. For example, in the last seven years, Enbridge had doubled its employees to 11,000. Guthrie concluded her overview by noting that Enbridge was recognized as one of the Global 100 Most Sustainable Corporations in the World.

This last claim got me thinking: if Enbridge can get that level of praise despite its shocking track record of 800 pipeline spills in the U.S. and Canada between 1999 and 2010, leaking 6.8 million gallons of oil and causing the largest inland heavy tar sands rupture in U.S. history, I wonder what the other energy companies are like.

Guthrie described the Line 5 as a 650-mile pipeline originating in Superior, Wisconsin traveling across the Upper Peninsula across the Straits of Michigan and down to Sarnia, Ontario. Line 5 is a 30-inch pipeline, except across the Straits where it divides into two 20-inch pipelines. Guthrie emphasized that Line 5 was carrying “light crude oil” which has “the consistency of skim milk.”

Blake Olson, Enbridge’s Escanaba Area Manager for over 400 miles of Line 5, followed with a presentation on the integrity of the Line 5 pipeline. He described Line 5 in the Straits as a one-inch thick seamless steel pipe, build with such a robust design that they just don’t build pipelines like this anymore. In fact, Olson commented that Line 5 at the Straits is the thickest pipeline in North America. Since 2012, Enbridge had increased the flow or volume of the product by 10 percent. Then he made the case that Enbridge had made a number of significant upgrades in their leak detection system within the last couple of years, including:

  • automatic shut-off valves at both sides of the Straits,
  • replacement of St. Ignace Valve Yard (2011) and Valve Yard containment system (2012),
  • the on-going installation of emergence flow restriction devices,
  • a back-up electric generator installed in 2013, and
  • a thermally imaging leak detection system to be installed this year.

In addition, Olson described Enbridge’s integrity protective system along Line 5, which included corrosion prevention with coal tar coating and cathodic protection, anchor strike prevention and brackets every 50 feet (coming this summer), monitoring with internal and external pipeline inspections, lighted shore signage and nautical charts stating DO NOT ANCHOR.

Too little, too late?

This was an impressive list to the casual listener/observer, but what troubled me was that a lot of these basic safety protections to ensure pipeline protection were recently instituted and this pipeline was 61-years-old. For example, in the 61 years of this pipeline’s history, the U.S. Coast Guard did not have nautical charts informing vessels about the very location of Line 5 until January 2014.  This change only happened because a number of concerned Michigan groups met with the Governor’s office to discuss Line 5’s safety in December 2013.

Olson assured the audience that Enbridge’s integrity program demonstrated that Line 5 under the Straits was “fit for service” with no dents or anomalies and met all federal pipeline regulations.

Before the Q&A session, Enbridge invited its contractor Bill Hazel from Marine Pollution Control to provide an overview of the emergency response measures set in place in the event of catastrophic spill on Line 5 under the Lakes. Hazel pointed to a number of simulated winter emergency response drills that Enbridge had participated in or serves as the lead in 2008, 2012, 2013, and this year. What became crystal clear was how catastrophic a Line 5 rupture would be especially during the wintertime. One follow-up question captured our imagination of this seemingly impossible mission: ‘May day, May day, May day!  It’s January 21, 2014 and it’s -9 °F and the wind chill is -25 °F, the Straits of Mackinac are frozen over, the ice four feet deep, and Line 5 has ruptured under the ice.  What are you going to do about it?’

Enbridge answers (some) public questions

Following a final word from the local emergency manager in Mackinac, Guthrie gathered the 5×7 questions cards, proceeded to sort them into piles, and distributed them to the appropriate Enbridge representative for answers at the podium. Several illuminating points came out:

  1. Line 5 only transports light crude oil, the consistency of skim milk.
  2. Line 5’s light crude oil currently comes the Bakken oil fields.
  3. There are no plans to pump heavy crude oil through Line 5.
  4. Seamless pipe wasn’t really a seamless pipe as Enbridge had described previously, rather Line 5’s two 20-inch pipelines are seamless only up to the joints that repeat every 40 feet along the 4-mile stretch along the bottomlands of the Straits.
  5. A wintertime spill would present unprecedented challenges in mounting an emergency response.
  6. If a rupture occurred and the automatic shut-off valves turned off in a 3-minute period, 5,500 barrels would be released and disperse over an area 25-square-miles wide.  This number was down considerably from 15,000 barrels before Enbridge installed the automatic shut-off valves.

The last question was: ‘If tar sands were being transported through Line 5, what pipeline changes would Enbridge have to make?’ Enbridge’s Guthrie pulled the card aside and said, “let me hold off on this question because it is complex.”  But time was on Guthrie’s side as the meeting ended sharply at 3:30 pm and she never had to answer this telling question.

The composed Midwestern temperament of the room quickly changed as audience members shouted out that their questions had not been answered.  But it was clear that the meeting was over.

The bottom line for the bottomlands

I walked out into the 12 °F air, looked out over the Straits and felt an urgent need for additional public forums in Mackinac and the Great Lakes to further educate and inform all walks of life who live here about Line 5. Enbridge had attempted to calm the public’s concerns about Line 5, but they hadn’t been entirely forthright and it bothered me. Without public transparency, we will need to engage the State of Michigan to assert its authority as trustee of the waters and bottomlands of the Great Lakes for the benefit of the public.

What I’m talking about is the public trust doctrine, which legally requires Governor Snyder and both the Department of Natural Resources and the Department of Environmental Quality, as state trustees, to ensure that Enbridge’s Line 5 under the Straits will not impair the public waters of the Great Lakes. This means that the State must demand full transparency and disclosure of all Enbridge’s activities not only for the people within range of a potential catastrophic spill, but for all residents of Michigan. Thus, if and when Enbridge decided to transport any type of heavy tar sands oil through Line 5, Enbridge has a duty to inform the state and the public and secure proper authorization under the Great Lands Submerged Lands Act. That’s FLOW’s take on the issue, and it’s what you will be hearing more about in the weeks and months to come. Stay tuned.

U.S. Army Corps to Limit Line 5 Tunnel Review

“The US Army Corps of Engineers decision to exclude the cumulative impacts of the fossil fuels Line 5 will transport, climate concerns, and, remarkably, engineering concerns raised by experts as to the integrity of the tunnel, flies in the face of the Corps’ purpose and mission, the Biden Administration’s goals and policy, and public concern for the protection of Great Lakes waters.” – Liz Kirkwood, FLOW Executive Director

FLOW Welcomes Court Order in Michigan Attorney General’s Case to Shut Down Line 5

Editor’s note: The following is a press statement from Zach Welcker, Legal Director of FLOW (For Love of Water), the Great Lakes law and policy center based in Traverse City, Michigan, in response to a federal district court’s certification on Tuesday of questions for interlocutory review by the U.S. Court of Appeals for the Sixth Circuit. The decision comes in the case of Nessel v. Enbridge, filed by Michigan Attorney General Dana Nessel on June 27, 2019, in the Michigan Circuit Court for the County of Ingham, to shut down the Line 5 oil pipelines in the Great Lakes. Members of the media can reach Zach Welcker, FLOW Legal Director, at Zach@flowforwater.org or by cell at 231.620.7911.


“This is a welcome development in Attorney General Dana Nessel’s effort to return to state court her state-law claims seeking the shutdown of Enbridge’s dual oil pipelines on state-owned bottomlands in the Straits of Mackinac. FLOW credits her petition for mandamus—filed just two business days before the certification order—for prompting the federal district court to finally take action on a motion that the Attorney General filed more than five months ago.

“Although the district court’s order does not guarantee that the Sixth Circuit will agree to resolve the certified questions, we are hopeful that the Court will recognize that interlocutory review is necessary to protect the fundamental state rights that are undermined by the district court’s erroneous procedural and jurisdictional rulings. 

“The Attorney General’s extraordinary efforts to obtain appellate review before the right is available via direct appeal is a testament to her commitment to protect the Great Lakes—and our public rights to use and enjoy them—from being impaired by Enbridge, the same company that is responsible for the Kalamazoo River oil-spill disaster,” said FLOW Legal Director Zach Welcker

Hundreds Attend Army Corps Hearing, Strong Majority Speaks Out against Proposed Oil Pipeline Tunnel under the Great Lakes

Katie Otanez, Regulatory Project Manager for the U.S. Army Corps of Engineers, Detroit District, delivers a presentation on Sept. 8, 2022, in St. Ignace, Mich., while Army Corps staff look on.

Five-and-half hours into a marathon federal hearing that lasted seven hours on Thursday, September 8, in St. Ignace, Michigan, more than 4 out of 5 people who spoke said that an oil pipeline tunnel proposed under the Great Lakes was a dangerous idea that would rob future generations by threatening the most precious thing on earth — fresh water — and worsening the climate crisis.

The U.S. Army Corps of Engineers held the public comment session to help set the scope of its environmental impact statement study of a proposal by Enbridge, Inc., of Canada, to build an oil tunnel under the Straits of Mackinac to house its Line 5 oil pipeline, which carries oil from western Canada primarily to refineries in Sarnia, Ontario. The Army Corps study is expected to continue through at least 2023.

Hundreds of people attended the meeting at Little Bear East Arena, a local hockey facility just north of the Mackinac Bridge in the eastern Upper Peninsula, with each commenter taking up to three minutes to address the Army Corps staff seated up front. Most people expressed deep concern for the harm that construction or a potential explosion or spill from the operation of an oil pipeline tunnel could have on their children and grandchildren’s future, local residents, the Great Lakes, drinking water, tourist economy, and jobs — as well as tribal rights, tribal member survival, cultural heritage, the fishery, ecology of the Straits of Mackinac, and the climate.

Whitney Gravelle, president of the Bay Mills Indian Community, was the first to speak at the Army Corps meeting against the tunnel proposal and sought to change the narrative promoted by Enbridge in its multimillion-dollar advertising campaign. “Line 5 is not about Enbridge. It is not about jobs. It is not about profit. It is about the continued existence of my people here in the State of Michigan.”

“We rely on all of those natural resources to be able to live, to be able to support our families and just exist as Anishinaabe people,” said President Gravelle, emphasizing that more than half of Bay Mills tribe members depend on their treaty rights to hunt, fish, and gather for subsistence.

Ian Bund, venture capitalist

Ian Bund, a venture capital investor who attended the hearing on his birthday to oppose the tunnel project, said, “There’s no evidence that Enbridge’s board of directors has approved the tunnel. Is it a PR stunt? Enbridge is largely uninsured, uninsurable, and un-bondable…. There’s no evidence how Enbridge would finance the tunnel project. One wonders if they might look to taxpayers.”

Enbridge, in fact, lacks adequate liability insurance, according to a report released by the Attorney General Dana Nessel’s office revealing that Enbridge’s subsidiaries, not its parent company, hold Line 5’s 1953 easement and signed the proposed tunnel agreement; the assets of the subsidiaries’ parent Enbridge are inadequate to cover the costs and economic damages in the event of a moderate spill.

Many Troubling Aspects of the Tunnel Proposal

Enbridge is proposing to bore and blast a 20-foot-in-diameter tunnel under the Straits of Mackinac to house a new Line 5 pipeline. The Canadian company’s goal is to continue for another 99 years carrying up to 23 million gallons of oil and natural gas liquids a day through Line 5 and State of Michigan public trust bottomlands where Lake Michigan meets Lake Huron, just west of the Mackinac Bridge.

FLOW and our partners have identified critical deficiencies in the project’s construction permit application, its legal authorization, and the review by State of Michigan environmental agencies of expected impacts to wetlands, bottomlands, and surface water, including from the daily discharge of millions of gallons of wastewater during construction. FLOW has expressed continuing concerns about the impact to the Great Lakes and lack of public necessity for the project, which would worsen climate change by adding greenhouse gas emissions each year equivalent to almost seven new coal-fired power plants or nearly 6 million new cars to the road, according to experts.

FLOW’s position, as expressed at the hearing in St. Ignace, is that the Army Corps’ environmental study of the tunnel proposal and alternatives must include, at a minimum:

  1. A no action alternative that would use existing capacity in other pipelines and, if necessary, other transportations solutions–such as rail and truck transport of natural gas liquids–in lieu of building new pipeline infrastructure.
  2. An alternative to connect Enbridge’s Superior, Wisc., and Sarnia, Ontario, terminals without crossing the Great Lakes. (See FLOW’s fact sheet on alternatives).
  3. A tunnel alternative that fully eliminates the risk of oil intrusion into the Straits in the event of an explosion or similar event.

Tribal Nations, agencies, communities, organizations, citizens, and other stakeholders can comment on the tunnel proposal through Oct. 14, 2022, via mail, through the Army Corps project website, or at the Army Corps’ Oct. 6, 2022, online meeting. The Oil & Water Don’t Mix campaign, of which FLOW is a founding steering committee member, also is collecting and forwarding comments to the Army Corps using an email template that suggests key points to make.

Oil & Water Don’t Mix Campaign Mobilizes Great Lakes Advocates

The Oil & Water Don’t Mix campaign chartered two buses that gathered people in Ann Arbor, East Lansing, and Traverse City to attend the Army Corps’ September 8 meeting, with FLOW, the Sierra Club Michigan Chapter, and several other allied groups helping organize the effort. Many riders wore the campaign’s black t-shirts with white letters proclaiming “No Line 5 Oil Tunnel.” At the session, Enbridge and some allied trade unions also wore bright blue or orange shirts expressing support for the proposed tunnel or labor to show their solidarity.

Kim Gribi of Traverse City

Lana Pollack, former U.S. Chair of the International Joint Commission

Several people, including Lana Pollack, former U.S. chair of the International Joint Commission, called Enbridge a “bad actor” with a long history of oil spills from Line 5, which runs through the Straits, and Line 6B in southern Michigan that burst in 2010 into the Kalamazoo River watershed.

Kim Gribi, a concerned citizen from Traverse City, also pointed to Enbridge’s “bad track record.” Gribi said that with her professional background in human resources and evaluating applicants for jobs, when it comes to the tunnel project and Enbridge, “I wouldn’t hire them.”

Barbara Stamiris of the Northern MI Environmental Action Council

Barbara Stamiris of the Northern Michigan Environmental Action Council and others questioned whether the tunnel proposal was a delay tactic by Enbridge to allow the Canadian energy-transport giant to keep running its Line 5 oil pipelines indefinitely in the open waters of the Straits of Mackinac, despite a standing order issued in November 2020 by Gov. Gretchen Whitmer to shut down the risky 69-year-old pipeline segment.

A number of people in their public remarks in St. Ignace requested that the Army Corps extend the 60-day comment period on the proposed tunnel and hold additional in-person meetings downstate to reach more people on such a critical matter as the future of the Great Lakes and the drinking water supply.

FLOW: There’s No Alternative to Fresh Water

FLOW Board member Barbara Brown, a St. Ignace resident who served for 14 years on the Mackinac Bridge Authority, pointed to what the region must protect above all else: our freshwater heritage. “We are rapidly moving toward alternative forms of energy. Enbridge already has, in Line 78 [in southern Michigan], an alternative route of deliveryWhat we do not have is an alternative to water.”

“We are rapidly moving toward alternative forms of energy. Enbridge already has an alternative route of deliveryWhat we do not have is an alternative to water,” said Barbara Brown, FLOW Board Member and St. Ignace resident

In fact, the North American energy pipeline system operated by Enbridge and its competitors has available capacity and flexibility to meet energy demand in the Great Lakes region without threatening public waters and the economy, according to multiple studies. One of Enbridge’s own experts has concluded gasoline prices will rise by about only half a penny in Michigan if the Line 5 oil pipeline shuts down.

“We are sitting today at the very heart of 20% of the world’s fresh surface water,” Brown said. “With much of humanity and the animal world on the brink of death for want of water, and we being at the center of the largest body of fresh surface water on the planet, it is bordering on the immoral to even entertain the unnecessary, continued operation of Line 5 through the Great Lakes whether by pipe or tunnel.”

As FLOW’s Deputy Director, I (the author of this article) helped coordinate the bus from Traverse City and in my comments, said, “The Straits of Mackinac is the worst possible place to build and operate an oil pipeline tunnel. Any rupture, explosion, or other event resulting in a major oil spill in the Straits would contaminate the very heart of the Great Lakes, which hold 95% of the fresh surface water in the United States.”

As a result, “the Army Corps’ Environmental Impact Statement or ‘EIS’ review of the project should be scoped to eliminate the risk of a pipeline-related oil spill into the Great Lakes.” (Click to read Kelly Thayer’s full comment delivered on behalf of FLOW).

Regional and Binational Perspectives

Beth Wallace of the National Wildlife Federation

Michelle Woodhouse of Environmental Defence in Canada

Michelle Woodhouse, representing Environmental Defence Canada, came from Toronto to convey that many Canadians want to move rapidly away from oil extraction as a key driver of the economy in order to cope with the “climate emergency.” Woodhouse also pointed to indigenous cultural artifacts in the Straits of Mackinac that could be damaged by the tunnel proposal and said “clear alternatives exists” that would not harm the Great Lakes.

Beth Wallace of the National Wildlife Federation, Great Lakes Regional Center, spoke next and emphasized that Enbridge’s history of nearly three dozen oil spills from Line 5 and the 2010 oil spill disaster from Line 6B in Marshall, Michigan, are forewarnings of what could happen in the Straits of Mackinac.

Maya Ponton Aronoff pointed to better ways for Enbridge and trade workers to aid the residents of Michigan than building an oil pipeline tunnel under the Great Lakes.

“[Enbridge] could be replacing every lead-lined water pipe in Michigan that’s poisoning our children and our communities. They could be investing in renewable energy, creating jobs in solar and wind. They could be doing anything with their billions of dollars. But they’re making us believe this lie that we have to choose between jobs and our future,” said Maya Ponton Aronoff

“[Enbridge] could be replacing every lead-lined water pipe in Michigan that’s poisoning our children and our communities,” Ponton Aronoff said. “They could be investing in renewable energy, creating jobs in solar and wind. They could be doing anything with their billions of dollars. But they’re making us believe this lie that we have to choose between jobs and our future.”

Army Corps Process to Continue through at Least 2023

Enbridge’s has applied for a Army Corps permit under the Rivers and Harbors Act of 1899 and the Clean Water Act, seeking federal approval to discharge dredged or fill materials into waters of the United States, as well as the construction of structures or work that may affect navigable waters. The Army Corps also will conduct an ethnographic/traditional cultural landscape study as part of the environmental impact statement under the National Historic Preservation Act. After considering public comment and issuing the draft EIS likely by fall 2023, the Army Corps will seek additional public feedback, release a final study, and then issue a “record of decision” regarding whether to issue, issue with modification, or deny the Department of the Army permit altogether — consistent with the National Environmental Policy Act.

The Army Corps, Detroit District, to date has identified general concerns in the following categories:

  • Potential direct effects to waters of the United States including wetlands; water and sediment quality; aquatic species and fisheries; threatened and endangered species;
  • Archaeological and cultural resources, including the Straits as a Traditional Cultural Landscape; Tribal treaty rights and interests;
  • Recreation and recreational resources; waste management; aesthetics; noise; air quality; climate change, including greenhouse gas emissions and the social cost of greenhouse gases;
  • Public health and safety during construction and operations; navigation; erosion; invasive species; energy needs; environmental justice; needs and welfare of the people; and cumulative effects.

FLOW’s legal team aided in this effort in December 2020 by submitting comprehensive comments to the U.S. Army Corps of Engineers calling for an environmental impact statement on behalf of a dozen organizations: Chippewa Ottawa Resource Authority, Clean Water Action—Michigan, FLOW, Groundwork Center, League of Women Voters of Michigan, Michigan Environmental Council, Michigan League of Conservation Voters, NMEAC, Sierra Club Michigan Chapter, Straits Area Concerned Citizens for Peace, Justice and Environment, Straits of Mackinac Alliance, and TC 350. The comments demonstrated a serious gap in Enbridge’s evaluation of the presence of loose, unconsolidated rock and sediment in the bottom of the Straits of Mackinac that Enbridge has characterized as solid bedrock.
