Ecological disasters do not wait for political elections.

Ecological disasters do not wait for political elections.

And Line 5 at the Straits of Mackinac seems oblivious to the campaign calendar.

To date, the Band-Aid fix-it approach for line 5 has only resulted in Band-Aid size – oh, I mean dinnerplate size -- bare metal spots on the pipeline itself.

The law is clear. Public trust waters are the paramount interest and must be the priority of state protection and action.

Enbridge's ongoing violations on Line 5 are blindingly obvious. And they have continued to mount over the last three years while the state has delayed a safe solution through endless study. A quick sampling of violations includes: lack of adequate anchor supports, loss of protective coating, bent pipeline, bare metal, lack of a credible emergency oil spill response plan, deficient liability insurance, and so on.

Time and time again, Enbridge has asked the public and the state to trust them. And we have only later found out that Enbridge has misled the citizens of Michigan and the state government about the true condition of their aging 64-year-old dual pipelines.

Enbridge has an outstanding permit request to install 22 additional anchors. But the state is in no position to authorize these permits because the anchors themselves have caused the bare metal exposure on the pipeline.

Now the state has decided to engage university experts to spend months finishing a risk study put on hold last summer due to contractor conflicts of interest. A risk study only further delays meaningful state action on Line 5 to avoid a pipeline oil spill. We already know that the risk of any oil spill in the heart of the Great Lakes is unacceptable. Thus, we are merely asking ourselves: How fast will the Titanic sink? 1 hour or 3 hours.

Any credible risk study will simply conjure a more realistic disaster scenario than Enbridge would like us to imagine. It appears that the state is committed to completing the risk study; however, it should at the very least recommend that the state temporarily shut down the flow of oil while the risk study marches on.

No one today would ever authorize oil pipelines to pump 23,000,000 gallons of oil daily in the open waters of the Great Lakes. While consultants completes a risk analysis, the state at a bare minimum should temporarily shut down the flow of oil.

So let's be clear ourselves. Line 5 must be decommissioned and we, the citizens of Michigan, demand that this process starts immediately.

The time to act is now.

Statement to Pipeline Safety Advisory Board

Line 5 Pipeline

The state pipeline safety advisory board met Monday to discuss next steps on Line 5 at the Straits of Mackinac, in the wake of new revelations about shoddy Line 5 maintenance by Enbridge. FLOW's statement at the meeting said enough is known about the pipeline's condition and poor maintenance for the state to immediately revoke the pipeline's easement to traverse the Straits.


 

FLOW Comments on the Draft 2017 Lake Huron Lakewide Action and Management Plan

Line 5 Pipeline

Tuesday, FLOW submitted comments regarding the draft 2017 Lakewide Action and Management Plan (LAMP) for Lake Huron.  We are concerned about the LAMP’s failure to address a major threat to the waters and ecosystem of Lake Huron: the Enbridge Corporation’s Line 5 pipelines traversing 4.6 miles on the bottomlands of the Straits of Mackinac.

A Disappointing Distraction: FLOW’s Statement on the Line 5 Alternatives Study

On June 29, the State of Michigan released for public comment a consultant’s study on alternatives to Line 5, the risky 64-year-old dual oil pipelines that cross the lakebed of the Straits of Mackinac.  The state is now holding public meetings on the study.

The study is a major disappointment and contributes little of value to the discussion on the fate of the oil pipelines operating in the Great Lakes since 1953. 

FLOW’s position is unchanged:  the State of Michigan must terminate the easement allowing Enbridge to use Lake Michigan’s lakebed for the pipelines.  The state has the authority and the responsibility to do so to prevent a catastrophic oil spill.  In light of Enbridge’s consistent record of disregard for maintenance of Line 5, the state must do so.

* FLOW rejects the alternatives study as fatally tainted by the authors’ blatant conflict of interest. The consulting firm’s vice president has an extensive history of working alongside of, and in support of, Enbridge.  The state’s process is now revealed for what it always has been – a distraction from its responsibility to protect the Great Lakes by shutting down Line 5 now.

* Substantively, the alternatives study can’t be taken seriously because it:

  1. Completely ignores the most suitable alternative to Line 5, which is existing infrastructure. The state asked consultant Dynamic Risk to analyze it. Failure to do so skews the analysis. Since the state and consultant won’t do their jobs and analyze the existing infrastructure, FLOW will continue to analyze it by updating our 2015 independent expert report on that alternative in the near future.
  2. Assumes the best-case scenario for a spill. The consultant uses assumptions of risk that are woefully inadequate and are not credible. It estimates that:
  • Only 20 miles of shoreline would be impacted by a spill. This is just 3% of the 720-mile area the University of Michigan found vulnerable to a spill in its 2016 study.
  • An oil spill would cost $100 million to $200 million, when Enbridge’s cleanup costs for its Line 6B pipeline oil spill into the Kalamazoo River watershed in 2010 cost more than $1.2 billion.
  1. Inflates the impact of shutting down Line 5 to the U.P.’s propane supply. The report estimates an impact to propane supply much greater than what FLOW’s independent experts have determined would be necessary to provide the Upper Peninsula’s Rapid River facility with an alternative supply. The flawed report finds that up to 35 railcars per week or 15 truckloads per day would be necessary to replace the Line 5 supply of natural gas liquids, while FLOW’s expert studies have found it would take only one railcar or 3 – 4 truckloads per day.

FLOW is a leader in the Oil & Water Don’t Mix campaign uniting citizens, businesses, groups, governments, tribes, and faith communities in support of shutting down Line 5 to avoid a catastrophic Great Lakes oil spill.

State of Michigan Takes a “Holiday” from Preventing Line 5 Oil Spill Disaster in Great Lakes

Snyder Administration Watches and Waits as the 64-year-old Dual Pipelines Missing Their Anti-Rust Coating and Structural Supports Continue to Use Mackinac Straits as a High-Risk Shortcut to Private Profits

TRAVERSE CITY, MI – The Snyder administration, in two letters (here and here) released Wednesday, indicated it will seek more information, but take no enforcement action, while continuing to accept Enbridge’s assurances that all is well with dual oil pipelines in the Mackinac Straits that the Canadian company itself has indicated are missing portions of an external, anti-rust coating and lacking 18 anchor supports to prevent the pipes from grinding and bending along the bottom and bursting.

The letters – signed by Attorney General Bill Schuette, Michigan Department of Natural Resources Director Keith Creagh, and Michigan Department of Environmental Quality Director Heidi Grether – describe “inviting” Enbridge to explain the company’s September 2016 report that identifies 19 areas along the submerged steel pipes where the anti-corrosion coating is missing. Enbridge’s report euphemistically calls the missing portions “holidays,” industry jargon for areas where the coating has worn or fallen off. The report outlines a plan for assessing Line 5’s integrity where the coating is gone and acidic waste excreted by invasive mussels that blanket the pipes could be causing corrosion.

Enbridge claims that the report is merely “hypothetical,” even though the report flatly states that the external coating is missing and the words “hypothetical” and “theoretical” are not found in the document.

“The State of Michigan is moving in slow motion to question Enbridge’s claims that its own report doesn’t mean what is plainly says,” said Liz Kirkwood, an environmental attorney and executive director of FLOW, a Traverse City-based water law and policy center dedicated to upholding the public’s rights to use and benefit from the Great Lakes. “When the pipelines finally fail, will the state invite Enbridge to explain what the thick, black substance is pouring out of the 64-year-old pipes and into the drinking water source for nearby Mackinac Island, St. Ignace, and roughly 5 million Michiganders?”

The state issued its March 8 letter in response to February 17 correspondence from the Oil & Water Don’t Mix campaign, which FLOW co-leads with several other leading organizations, that raised grave and detailed concerns about the condition of Line 5 and called for its immediate shutdown.

An Enbridge representative is expected to explain its report at the March 13 quarterly meeting in Lansing of the governor-appointed Michigan Pipeline Safety Advisory Board, whose members include Attorney General Schuette. The advisory board is overseeing the completion of two nominally independent studies funded by Enbridge: one on the financial risk to communities and the Pure Michigan economy of a Line 5 oil spill in the Mackinac Straits and the other on alternatives to the aging pipeline that could avoid such a disaster. These two studies are expected by June 2017.

Enbridge is infamous for leaking more than one million gallons of heavy tar sands oil into the Kalamazoo River watershed near Marshall, Michigan, in 2010, fouling nearly 40 miles of the river and shore, sickening numerous people, harming wildlife, and forcing more than 100 families to permanently abandon their homes and property.

The failure to adequately maintain the Line 5 pipelines, including a lack of supports to prevent bending of the pipeline – is a breach of Enbridge’s 1953 legal easement agreement with the State of Michigan that allows the company to occupy public waters and state bottomlands. The failures documented in the Enbridge report add to the mounting evidence of the unacceptable risk that this infrastructure poses to the Great Lakes.

A three-minute video of Line 5 pipelines in the Straits, researched and edited by FLOW’s engineering expert Dr. Ed Timm, reveals the physical deterioration of Line 5, with missing and dislodged coating, broken bands, detached wooden structural slats, unsupported segments, and possible rust and pitting.

In addition, a just-released technical note prepared by Dr. Timm regarding Line 5 reinforces the urgent need for the state to immediately shut down Line 5 while it evaluates the integrity of the aging infrastructure that pumps nearly 23 million gallons of oil a day through the Mackinac Straits before eventually reaching refineries in Sarnia, Ontario. Specifically, this technical note concludes the following:

  • Line 5 is not immune to corrosion and stress cracking despite its thick walls, contrary to Enbridge’s claims;
  • The asphalt enamel based coating system is compromised or missing on many areas of the pipe;
  • The extent of the coverage by invasive mussels on the pipelines makes it “impossible” to evaluate how much of the coating system is compromised;
  • The easement-required wooden slats that were designed to protect from point loads and abrasion are missing entirely on portions of the pipelines; and
  • The peak currents in the Mackinac Straits are nearly twice the maximum velocity considered when the pipeline was designed, adding significant stress;
  • A full study of the integrity of the coating system that includes a careful examination of the impact of the biofouling on the pipelines is critical to making a proper fitness-for-service evaluation.

“The evidence demands that the State of Michigan respond and fulfill its affirmative fiduciary duty,” wrote Jim Olson, an environmental attorney and FLOW’s president, in a March 9 follow-up letter to the State of Michigan. “It is not enough to stand by the sidelines and merely request additional information from Enbridge given the high risk of a catastrophic oil spill in the Great Lakes that would devastate our public drinking waters and our water-dependent economy. ‘Pure Michigan’ should not just be an advertising slogan.”

FINAL FLOW-Line 5 Media Release-Pipeline Coating 3-9-2017

State Must Stop Oil Flow, Hold Public Hearings on the “Line 5” Oil Pipelines in the Mackinac Straits

Under Michigan law, the state must stop Line 5’s oil flow and hold public hearings on the steel pipelines lying underwater in the Mackinac Straits as it considers Enbridge Energy’s application to remedy easement violations and shore up its aging underwater infrastructure, according to FLOW (For Love of Water), a Traverse City-based Great Lakes water law and policy center, in formal comments released today.

For the ninth time since 2001, Canadian energy transport giant Enbridge is seeking state permission to screw large pipeline anchors into Lake Michigan’s public bottomlands where the Straits’ powerful currents have eroded the lake bottom and left the dual Line 5 pipelines – installed in 1953 – unsupported for long stretches, in violation of the state easement agreement limiting unsupported spans to 75 feet. The Michigan Department of Environmental Quality (MDEQ) is receiving public comment through August 28, 2016, on Enbridge’s application, which also is being reviewed by the U.S. Army Corps of Engineers.

FLOW’s legal analysis concludes that Enbridge’s “maintenance” application to install up to 19 more anchors actually disguises Enbridge’s piecemeal actions that continue to significantly expand oil transport through and around the Great Lakes. In addition, the application fails to address Enbridge’s pattern of easement violations and perpetuates the imminent threat to the Great Lakes and the public’s protected uses thereof that include fishing, commerce, navigation, recreation, and drinking water. Line 5 transports nearly 23 million gallons of oil and natural gas liquids each day through the Mackinac Straits, 80 percent more volume than its past design capacity after several of its so-called “maintenance” upgrades.

“Between Line 5 and the new Line 6B, Enbridge has quietly built its own massive crude oil pipeline system here in Michigan and the Great Lakes without adequate public notice, hearings, and the legally required analysis and determinations of potential risks, impacts, and alternatives for a project of this magnitude,” said Jim Olson, FLOW’s founder and president and a renowned water rights attorney.

Given the scope and risk, the state must stop the Straits oil flow at least temporarily, hold public hearings, and examine Line 5’s full range of potential impacts to the Great Lakes ecosystem and alternatives that do not pose such harm, rather than continue to rubberstamp Enbridge’s misleading maintenance applications. The Michigan Pipeline Safety Advisory Board is conducting a parallel review of Line 5 in the Straits slated for completion in late 2017 or early 2018, but that process is neither under the rule of law nor complies with the Great Lakes Submerged Lands Act (GLSLA) or other state and federal law.

“It is time for our state’s leaders, specifically DEQ Director Grether and Attorney General Schuette, to bring this matter under the rule of law – the GLSLA and public trust law – that protects our Great Lakes, towns, and citizens, and subject Enbridge to a comprehensive review,” Olson said. “Such a review must address the fact that Line 5 is an unacceptable risk and that there exists a new Line 6B from Illinois and across Michigan that Enbridge replaced and doubled in size after its Kalamazoo River oil that will meet current and future Midwest demand.”

“Based on the evidence, it appears that Enbridge has shoved its own version of the ‘Keystone XL’ through the Great Lakes and on the backs of citizens without any review of the risks, harms, and alternatives. This is the worst place on the planet for it. We don’t need a ‘Great Lakes XL’ for crude oil near our Great Lakes or in the Straits of Mackinac, especially where alternative to Line 5 exist,” Olson said.

Of particular concern is Enbridge’s continued failure to predict and prevent the cumulative impacts on Line 5 of lakebed erosion caused by Straits currents that frequently reverse and can exceed 10 times the flow over Niagara Falls.

“Enbridge’s piecemeal approach to managing washouts and installing adequate support under the Straits crossing of Line 5 has resulted in the line frequently being out of compliance with easement support requirements since the 1970’s,” said Ed Timm, PhD, an engineer advising FLOW. “Washouts are inherently unpredictable and it is likely that damage to the pipe has already occurred because of unsupported spans that were not detected and repaired by Enbridge’s two-year inspection and repair schedule.”

While the state’s 1953 easement agreement granting Enbridge conditional occupancy of state bottomlands allows Enbridge up to 90 days to cure any violations, the erosion problem appears to be unfixable and worsening with time.

“The Achilles’ heel of the state easement agreement is that Enbridge has proven itself unable to remain in compliance and therefore frequently is operating illegally,” said Liz Kirkwood, FLOW’s Executive Director and an environmental attorney. “State law demands that the Great Lakes and their public uses must not be risked for Enbridge’s private benefit. It’s time for the state to defend the public’s rights and prevent a catastrophic oil spill into the drinking water supply for half of Michigan residents, and for a total 40 million people in the U.S. and Canada.”

Stopping Line 5’s oil flow in the Mackinac Straits to prevent a catastrophic oil spill would not disrupt Michigan’s or the Midwest’s crude oil and propane supply, contrary to assertions by Enbridge, according to a set of expert reports FLOW released in December 2015. Available capacity and flexibility to meet energy demand in the Great Lakes region already exists in the North American pipeline system run not only by Enbridge, but also by competitors supplying the same refineries in Detroit, Toledo, and Sarnia, Ontario.

“The fact is, Line 5 is not essential,” said Rick Kane, a Michigan-based hazardous materials risk management specialist advising FLOW. “The regional pipeline system can supply crude oil to Michigan and surrounding refineries while eliminating the risk that Line 5 poses to the Great Lakes,” Kane said. “Feasible and prudent alternatives exist to support domestic needs, as well as exports.  However, pipeline company owners will not move to implement any alternatives as long as Line 5 operates and the public continues to carry the risk.”

End Enbridge Stonewalling

Observations by some that the State of Michigan has no regulatory authority over hazardous liquid pipelines is correct to the extent that it is understood in the context of  safety regulations — standards, inspection and enforcement; safety code enforcement is covered by the federal PHMSA law, regulation and agency.  However, it is not true that Michigan does not have authority to demand the information Enbridge keeps under its control, and it is not true that Michigan does not have enforcement authority.

As concluded by the Michigan Petroleum Pipeline Task Force Report, 2015, Michigan has authority under the 1953 Easement, including the continuing obligation of Enbridge to conduct itself with prudence at all times, and it has authority under:

(1) its sovereign ownership of bottomlands and waters of the Great Lakes since statehood in 1837 under “equal footings” doctrine. Michigan took title in trust to protect the basic rights of citizens as beneficiaries of a public trust imposed on the state.  This means the state has authority and duty to take actions to protect the public trust as a matter of its “property and public trust power,” whether or not it passes regulations on hazardous liquid pipelines or not.  Under public trust authority and principles, the state cannot transfer or shift control over waters and bottomlands held in trust to any private person or corporation; the retention of information by Enbridge that is required to protect the public trust or to determine whether the public trust is threatened with high unacceptable harm or risk violates this public trust principle, and the Attorney General can demand and take all action necessary to compel Enbridge to turn it over, indeed, even the easement recognizes and is subject to this public trust.

(2)  The Michigan Public Service Commission has authority over siting and locations of crude oil pipelines like Enbridge’s and others.  Anytime Enbridge or some other corporation applies for a change or improvement to the structure it regulates as to siting, including its consideration of risks to property and health or environment and alternatives, the MPSC has authority to demand all relevant information needed to  make a decision on the application for such change.  Unfortunately, the MPSC has not insisted on the full range of information it could demand, including alternative pipeline routes and capacity to Line 5 in the Straits of Mackinac when it doubled capacity for Enbridge’s new replacement for the failed Line 6B that ruptured into the Kalamazoo River in 2010.

(3) Finally, the Michigan Environmental Protection Act, Part 17,  NREPA, imposes a duty to prevent and minimize harm to air, water, and natural resources, and this includes the right to take action where necessary when a corporation’s actions are contrary to this duty to prevent and minimize harm; the MEPA, as it’s  often called, is derived from Art 4, Sec. 52 of the Michigan Constitution.

So while Michigan ponders the aging or new pipeline infrastructure for hazardous liquids and crude oil, the state, including the Attorney General, have the authority to take immediate action to prevent the high risk of Line 5 or other pipelines.  And, where that risk involves the devastating harm that undoubtedly may occur in the Straits, action should be taken immediately pending the coming one to two years of pondering.  In short, there is no legal excuse or justification for Governor Snyder, Attorney General Bill Schuette, or the Department of Environmental Quality to put up with Enbridge’s self-serving stonewalling on disclosure of all information related to its Line 5 hazardous crude oil pipeline.  And, there is no excuse or justification for our state leaders to delay action to eliminate the unacceptable harm from the Straits or other Michigan waters from Line 5.

 

 

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.”

Can the Mackinac Bridge be used to support the pipelines?

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!

U-M computer model shows Straits pipeline break would devastate Great Lakes

July 10, 2014

A rupture of 61-year-old, underwater oil pipelines running through the Straits of Mackinac would be “the worst possible place” for a spill on the Great Lakes, with catastrophic results, according to a University of Michigan researcher studying potential impacts of a spill.

David Schwab, a research scientist at the U-M Water Center, retired from the National Oceanic and Atmospheric Administration, where he studied Great Lakes water flows and dynamics for more than 30 years. He’s the author of a new study done in collaboration with the National Wildlife Federation looking at different scenarios for potential oil spills in the Straits from Canadian oil transport giant Enbridge’s Line 5.

“I can’t think — in my experience — of another place on the Great Lakes where an oil spill would have as wide an area of impact, in as short of time, as at the Straits of Mackinac,” Schwab said.

Line 5 is a set of two oil pipelines that runs from Superior, Wis., through the Upper Peninsula, underwater through the Straits and then down through the Lower Peninsula before connecting to a hub in Sarnia, Ontario. The lines transport about 23 million gallons of oil and other petroleum products, such as natural gas liquids, through the Straits daily.

A July 2010 spill near Marshall caused by a ruptured Enbridge pipeline, and concerns about the underwater pipeline through the Straits, already has prompted state and federal scrutiny. Michigan U.S. Sens. Carl Levin and Debbie Stabenow have sought information on Line 5, as have several members of Congress. And state Attorney General Bill Schuette and Michigan Department of Environmental Quality Director Dan Wyant late last month announced they will cochair a multiagency government task force to look at petroleum pipelines and the health, safety and environmental issues they potentially pose in Michigan.

Part 1: Three years after oil spill, a slow recovery haunts Kalamazoo River

Part 2: Enbridge’s expanded oil pipeline draws ire of homeowners in its path

Schwab looked at six different scenarios — and all spelled a catastrophe for the lakes. That’s due in large part to the Straits of Mackinac being “really, a strange place on the Great Lakes,” he said. The strength of water flowing through the Straits is 20 times the amount necessary to keep Lakes Michigan and Huron at the same water level, he said. And the flows go in both directions — sometimes from Michigan to Huron, sometimes from Huron to Michigan — and change directions every few days.

Schwab created six animation models looking at what would happen if Line 5 ruptured at the northern, middle and southern end of the Straits — both at times when the water is flowing into Lake Michigan and when it’s flowing into Lake Huron. His projection was for a 1 million gallon oil spill lasting 12 hours.

“One million gallons is conservatively the amount of oil that resides in the pipelines in the Straits at any time,” he said.

The spill scenarios show that, depending on current directions, a spill could be transported eastward into Lake Huron, westward into Lake Michigan and move back and forth through the Straits several times. Shoreline areas most impacted would be Mackinac Island, Bois Blanc Island and the Lake Huron shoreline east of Mackinaw City. Contamination could spread as far west as Beaver Island in Lake Michigan to Rogers City in Lake Huron, the study found.

“What this report shows is (that) a significant oil spill in the Straits would be an ecological disaster for the Great Lakes,” said Andy Buchsbaum, regional executive director for the National Wildlife Federation. “It would severely impact shipping and tourism.”

Such a spill would severely damage “the Great Lakes brand,” Buchsbaum said. “The Straits of Mackinac are iconic. They are what many people think of when they think of the Great Lakes. It would be a death blow for the Great Lakes ecology and economy.”

Line 5 is older than an Enbridge oil pipeline that ruptured near Marshall in July 2010, causing the largest inland oil spill in U.S. history and necessitating a $1-billion cleanup of the Kalamazoo River and Talmadge Creek that is still not complete.

Enbridge spokesman Jason Manshum said the company shares the National Wildlife Federation’s “views on the critical nature of the Great Lakes ecosystem in general, and the Straits in particular.” This new report will advance “continued and meaningful discussion on pipeline safety in the Straits,” he added.

Manshum noted that Line 5 “has been incident-free since it was constructed in 1953, and through even greater oversight, the use of new technology and ensuring all risks are monitored — and, where necessary, mitigated — Enbridge is committed to maintaining this incident-free record into the future.”
