The Buck Stops With Them

FLOW reminds state leaders they have the power to defend the Great Lakes from Enbridge.

Governor Snyder and Attorney General Schuette have the legal authority to protect the Great Lakes from the major risk posed by the antiquated and poorly maintained Line 5 pipelines at the Straits of Mackinac, FLOW reminded them in a letter Thursday.

Responding to the latest comment by a state government official questioning the state’s authority to shut down the pipelines, FLOW wrote that the public trust doctrine and state statutes make that authority clear. And the same state officials have acknowledged that authority in the past.

“In the 1953 Easement authorizing the pipelines, Enbridge (then the Lakehead Pipe Line Company) and the State of Michigan acknowledged the state’s jurisdiction and property power and police power control over the Straits of Mackinac, because of the Great Lakes,” FLOW wrote. “It is undisputed that there can be no pipelines in the Straits or elsewhere in or under the Great Lakes or its connecting waters without a lease, occupancy agreement, or other written consent and a permit under the Great Lakes Submerged Lands Act from the State of Michigan.”

Despite such legal footing, DEQ Director Heidi Grether told reporters earlier this month, “People keep saying shut them down, shut them down; part of the question is, under what authority?”

But the state has already recognized its authority by requiring Enbridge at least since 2001 to obtain state permits for modifications of pipeline supports and a task force appointed by the governor concluded the state has jurisdiction. The state therefore has legal control of the use of the lakebed for a pipeline crossing, FLOW said.

“Years into state task force and advisory board review, state officials are trying to fall back on their alleged powerlessness to protect the Straits,” said Liz Kirkwood, FLOW’s executive director. “It’s merely an attempt to pass the buck. By entering into an agreement with Enbridge negotiated behind closed doors last November, the Governor was acknowledging that the state has a regulatory role in pipeline location.”

“The state’s authority is obvious and so is the correct course of action. The state must move to revoke the easement and shut the pipelines down before they rupture and do immense damage to the Great Lakes and Michigan’s economy.”

Saving the Straits of Mackinac

Saving the Straits of Mackinac

Yesterday, May 22, 2018, marks the day our stat’s citizens threatened with the terrible harm of an oil spill from a failed Line 5 in the Straits of Mackinac took matters into their own hands. The Straits of Mackinac Alliance (SMA) filed a contested-case petition with the Administrative Law Tribunal of Michigan. The tribunal hears cases, like a trial court, when citizens oppose state permits that violate the law. The SMA has filed a petition that would require the Department of Environmental Quality and Attorney General Bill Schuette to start applying state law that is supposed to protect the Great Lakes, and stop the flow of oil through Enbridge Line 5 in the Straits. The filing of this contested case is a major shift in this prolonged affair, a shift that will finally bring state officials and Enbridge under the rule of law. This essay explains why. But first, a brief history of what has happened to force citizens to take charge because leaders have failed to act is in order.

A Brief History

In September 2015, Michigan Attorney General Schuette staged a flurry of media events to proclaim that days of crude oil transport in the twin pipelines under the Straits of Mackinac “were numbered.” His exclamation came on the heels of the release of the Michigan Petroleum Pipeline Task Force’s report that concluded a spill in the Straits was unacceptable to anyone, that the State had jurisdiction over the siting and existence of the pipeline under a 1953 easement and the public trust in the Great Lakes that is embodied in a state law known as the Great Lakes Submerged Lands Act–the GLSLA. Enbridge was forewarned. The State was going to take charge, right?

Wrong. Within a few days, the media messaging from the Governor’s office was (to paraphrase): “Sure it’s days are numbered, but that number could be a long time.” Shortly after that, the Governor appointed the Michigan Petroleum Pipeline Advisory Board– a well-intended study commission with absolutely no power to do anything that would bind Enbridge or the State. The Advisory Board has met for almost three years now. Before the Board could agree on any suggested course of action for the State to address Line 5, in late 2017 Governor Snyder bypassed his own advisory board and unilaterally signed an agreement with Enbridge that establishes a framework for the long-term flow of crude oil across the Straits of Mackinac. The agreement gave Enbridge permission to replace the segment of Line 5 under the St. Clair River and to replace Line 5 on the bottom of the Straits with a tunnel or trenched pipeline to escape the strike of ship anchors. If not contested under rule of law that protects the public trust in the lakebeds and waters of the Great Lakes, the investment in replacement could all but seal the replacement of the 645-mile long Line 5. The agreement rubber-stamps Enbridge’s efforts to spend billions to entrench its own massive Keystone XL pipeline right here in the Great Lakes. Michigan has become the host state for the transport of Canadian tar sands oil to Canada and foreign ports, including that charming land of royal weddings– Great Britain. Why does the governor and not the law of the Great Lakes and the citizens of Michigan through our elected officials or under rule of law decide the fate of crude oil in and out of the Great Lakes basin?

But this is only half of the story. While the advisory board continued to hold meeting after meeting for the public to vent its frustration, the DEQ and Attorney General unwittingly if not unlawfully cooperated with Enbridge to keep the oil flowing through pipelines in the Straits, pipelines whose design is failing. Enbridge submitted information that showed loss of protective cover. Then the company disclosed the Kiefner Report, a 2016 survey of the twin pipelines that referred to a 2003 report that warned of scouring under the lines, leaving spans as long as 282 feet suspended in the water column above the lakebed and exposing the lines to powerful currents that could whip them back and forth like a coat hanger. The Kiefner report also disclosed a series of emergency measures to address the failure of the original design that was supposed to lay, tucked into the bottomlands under the Straits. In 2001, the company tried to stabilize the twin lines with grout bags. When these failed, the for the company fastened 16 saddles to the pipelines, supporting the saddles and lines by leg supports crewed into the lakebed. This was just the beginning. Scouring has plagued the integrity of these pipelines so much, that from 2001 to 2018, Enbridge has installed 150 supports– almost two miles of pipelines are suspended in the water like a bridge over the lakebed.

A New or Changed in Design

The installation of these anchor supports has completely changed the design of the pipelines in the Straits. And this has been done with the knowledge and help of the DEQ and Attorney General Schuette. Here’s how. Since 2014, Enbridge has filed several applications for permits under the GLSLA to install these anchor supports as “repairs” or “maintenance” measures.  Enbridge received its most recent “repair” permit on March 25, 2018 for the 22 supports mentioned above. In April Enbridge filed yet another application for 48 more supports to the pipelines— if approved, nearly 3 miles of pipeline originally designed in 1953 to lay on the lakebed will be suspended in the water!

How did Enbridge change miles of its original design as “repairs” or “maintenance?” The DEQ and Attorney General have dropped the ball. It’s called complicity. In 2017, citizens in the Straits, the Grand Traverse Band of Ottawa and Chippewa tribe, and For Love of Water (FLOW) filed extensive reports that demonstrated this substantial change in design carried serious and imminent risks. Evidence showed that currents or other natural forces pulled the anchors out of the lakebed, scraped off pipeline coating to bare metal, exposing the lines to corrosion. Equally disturbing, these reports demonstrated that the massive change in design of the pipelines has never been approved or authorized by the DEQ as required by law. Despite these proofs and clear legal requirements, the DEQ and Attorney General staff stonewalled the tribe’s and citizens groups’ patently obvious charge that miles of suspended pipelines were a new or substantial change in design, not “repair” or “maintenance,” subject to required comprehensive review under the GLSLA and public trust in the lakebed and waters of the Straits.

This spring, an anchor from a vessel struck a pipeline enclosing an electric line across the Straits that released contaminants. It turns out inspections have shown that the anchor struck the Enbridge pipelines, denting them by a half-inch. In addition to strong currents, the greatest risk identified by experts to the pipelines in the Straits is an anchor strike. Fortunately, the anchor struck near but not along segments of pipelines suspended above the lakebed.  If it had, the result could have been catastrophic. There’s nothing like a “repair” that changes the design of these pipelines in a way that will snag anchors dragging over them from a passing ship.

So what does the GLSLA say about these permits for “repair” or “maintenance?”  Nothing. The GLSLA law and regulations do not provide for these kind of under-the-radar permits. The DEQ and Attorney General have interpreted the law to favor Enbridge. In legal fact, the GLSLA requires that a new, altered or changed structure or improvement like the addition of miles of suspended pipeline in the waters of the Great Lakes must obtain a new agreement for occupancy and permit for the new pipeline design and structures. The GLSLA requires Enbridge to file a comprehensive study of all potential adverse impacts that could arise from such a change in design of the pipelines. The law and regulations also require Enbridge to prove there are no other feasible and prudent alternatives to Line 5 in the Straits– including the obvious adjustments to the capacity in Line 6b (now 78) across southern Michigan to Sarnia. The design capacity of Line 6b was doubled after the Kalamazoo River spill, and can handle crude oil flowing through Line 5 in the Straits.

Taking Matters Into Their Own Hands

In short, DEQ and Attorney General have sided with Enbridge in allowing the continued flow of oil in pipelines that have been substantially redesigned without authorization or approval under the GLSLA. Officials claim the supports are better than doing nothing, that some of them are required by a consent decree, that it’s a matter of safety for the pipelines. This misses the point. If there is no authorization under GLSLA for the new or modified design, and if it hasn’t been evaluated or permitted as required by the law, then why does it matter that oil should continue to flow through Enbridge’s pipelines? It doesn’t. If there is no authority, the new design has not been evaluated, the new design and existing line are failing, and risks are imminent, it is unlawful. For three years, government officials could have taken charge.

But they haven’t. All our leaders have to do is invoke the GLSLA law and rules, demand Enbridge obtain authorization and permits for the new design as a whole, and demonstrate no potential adverse effects, and no alternative. Until Enbridge does this, the GLSLA authorizes emergency measures or conditions– at this point quite obvious– to suspend the flow of oil in these dangerous lines until the company has the authority required by law. If the company cannot establish this according to the rule of law under the GLSLA, then the authorization and permits for this new or substantially changed design should be denied. Enbridge can use its thousands of miles connecting to other pipelines in North America. But there is no alternative if there is a spill or release in the Straits of Mackinac.

Jim Olson, President and Founder

I applaud the Straits of Mackinac Alliance and citizens and the Grand Traverse Band for filing a contested case. In my view, they are on solid ground. Finally, someone has decided to do the job that our government leaders should have done. I applaud my own organization for charting a course that brings Enbridge Line 5 under the rule of law, not a bureaucratic invention. I urge our Governor, Director of DEQ, and Attorney General to join the side of citizens and tribes and invoke the available rule of law under the GLSLA to protect the Great Lakes.


FLOW Demands State Reject Latest Enbridge Ploy


In comments submitted to state officials Friday, FLOW is urging state regulators to deny a bid by Enbridge Energy to install 48 new anchor supports on dangerous Line 5 at the Straits of Mackinac while evading scrutiny of alternatives that would protect the environment.

Enbridge’s latest request, if approved, would bring the number of anchor brackets to 198 that the governments have allowed the company to install since the early 2000s — completely changing the pipelines’ design. 

Structurally, this means that approximately 3 miles of pipeline are elevated in public trust waters above the bottomlands. But the design approved by the state in the 1950s had the pipeline resting in a trench on the lake bottom. 

“The fact that the Michigan Department of Environmental Quality and the U.S. Army Corps of Engineers continue to approve Enbridge’s anchor supports on the lakebed of the Lake Michigan as ‘repair’ and ‘maintenance’ is simply untenable,” FLOW says in its comments. “The highly increased risks of and alternatives to a completely modified design under both state and federal permitting laws requires a new agreement of occupancy and permits” under several laws.

“And given the recent anchor dents in the twin lines and rupture of the electrical line and release of toxic fluids, the risks to the Great Lakes are totally unacceptable,” FLOW said.

FLOW called on the state and federal governments to require that Enbridge:

  1. file a full and comprehensive application including a study of potential effects and feasible and prudent alternatives to Line 5 in the Straits in its entirety;
  2. suspend the flow of oil in Line 5 unless and until Enbridge files such application and evidence and obtains proper occupancy agreements, permits, or other approvals for this new or completely modified pipeline design; and
  3. consolidate into one application and examine the risks, impacts, and alternative analyses of the entire 645 miles of Line 5.

Anatomy of A Spill in the Great Lakes

Five years ago this spring, when I first learned about Line 5, I could only imagine what a catastrophic oil spill would look like here in the heart of the Great Lakes.  Two weeks ago, we dodged a bullet as we watched a hazardous liquid spill from two neighboring transmission cables unfold. What we witnessed was an anatomy of a spill — and how truly devastating an oil spill would be.    

Here’s what we know from the April 1st spill in the Straits.  

A release of at least 600 gallons of toxic coolant and insulating fluid from electric cables owned by American Transmission Company (ATC) occurred sometime Sunday afternoon in the Straits of Mackinac.  The dielectric fluid is a mineral oil that contains a benzene compound. ATC, however, did not report the release to the Coast Guard for 24 hours.  By Monday, ATC officials were blaming “extraordinary circumstances” like ice in the water and near the shore that hindered the emergency response.  

No cause was initially identified until days later.  The cause? Vessel anchor strike. News media coverage revealed the chaotic nature of responding to this hazardous liquid spill with Coast Guard helicopters looking for oil sheens and a multi-agency unified command assembling from federal, state, tribal, and local agencies and units.  Reports attempted to allay public fears, indicating that the product was so diluted that it would not pose a threat to drinking water supply intakes. The greatest threat posed was to wildlife and shore birds swimming in possible oil floating on the water’s surface.

On April 3, Enbridge – owner and operator of Line 5 – temporarily shut down the flow of oil in the pipelines to evaluate the leak detection systems.  Ten days after the ATC accident, on April 10, Enbridge notified state and federal officials that their pipelines had suffered three dents, likely due to the same vessel activity that may have caused the damage to the ATC lines.

Hold on.  Vessel anchor strike hitting Line 5?  This was the number one threat that Dynamic Risk identified in their November 2017 alternative report to the Governor-created Michigan Pipeline Safety Advisory Board.  Ironically, the original Bechtel engineers believed that a vessel anchor strike was only “one chance in a million.”

Well, two weeks ago that one chance in a million struck.  

And finally, a growing chorus of federal and state leaders from both sides of the aisle are demanding that Line 5 be shut down until a full visual inspection has taken place.  Tribal leaders like Aaron Payment from the Sault Tribe call for more comprehensive investigation and analysis: “These old pipes need to be shut off, at least until proper investigations and the full analyses are finished.” . . .  “Governor Snyder should not be using this accident as an excuse to fast-track a tunnel.”

Liz Kirkwood, Executive Director

So what can we learn from this?  First, we don’t need to imagine anymore.  We know that it might take up to 24 hours before the spill is even reported.   We know exactly how difficult it would be to deploy emergency responders to contain oil in the open waters.  We know how extreme the conditions are in the Straits, even in spring. We know about the challenges of ice. We know that we can never be 100% prepared in such a dynamic, chaotic, and extreme environment as the open waters of the Great Lakes.  Second, and most important, we can’t take a second chance because of the magnitude of harm and risk that Enbridge is asking citizens of Michigan to shoulder.

Let’s do the right thing. Michigan leaders – it’s time to be proactive and shut down this 65-year-old oil pipeline before it’s really too late.    


Once More: Line 5 and the Public Trust

byzantine-empire-public-land.-trusts

FLOW’s organizing principle is the public trust doctrine.  What sounds like an exotic concept is quite simple.  This centuries-old principle of common law holds that there are some resources, like water and submerged lands, that by their nature cannot be privately owned.  Rather, this commons – including the Great Lakes — belongs to the public.  And governments, like the State of Michigan, have a responsibility to protect public uses of these resources.  We explicitly address public trust concerns on what we’re calling Public Trust Tuesday.


Perhaps if they hear it often enough, they’ll act.

Michigan’s Pipeline Safety Advisory Board, established by Governor Snyder in September 2015, heard Monday from FLOW Executive Director Liz Kirkwood about the state’s public trust responsibilities.

It was FLOW that identified these responsibilities as the debate over unsafe Enbridge Line 5 at the Straits of Mackinac intensified several years ago.  Simply put, the public owns the lakebed under the Straits that Line 5 crosses – and state government, as the trustee, has the authority and the obligation to assure that any party granted an easement to use the public’s lakebed is not compromising the public uses protected by the trust.  The Legislature passed a law in 1953 granting Enbridge an easement across the Straits – subject to the public trust.

Enbridge has clearly fallen short of that standard with shoddy maintenance, concealment of damaging information and a track record of failure, culminating in the mammoth spill into the Kalamazoo River watershed in 2010. 

FLOW’s message Monday – Enbridge can comply with public trust interests and state law only if the state compels it to submit an application for the entire massive overhaul of Line 5 it seeks to undertake, and only with simultaneous consideration of feasible and prudent alternatives – including using other means to deliver the petroleum currently served up by Line 5.

Here are a few of Liz’s comments from Monday: 

“We are approaching the hour of decision on the fate of Line 5.  This process has been an epic example of how not to protect a world-class resource.  Transparency, corporate integrity and the rule of law have all been casualties. But there is one last chance to make it right.

“Enbridge has never applied for and DEQ has never comprehensively reviewed, considered, or authorized the new design with 128 screw anchors elevating the Line 5 pipelines off the lakebed.  This new design was not contemplated in 1953.  Moreover, the Great Lakes Submerged Lands Act does not authorize ‘activity’ permits that actually constitute a new design, permanent structures, and improvements on bottomlands or suspended in water areas above the bottomlands; rather, a new application is required in conformance with the public trust.

“The Great Lakes are held in trust by the State of Michigan as public trustee for the benefit of its citizens. The 1953 easement with Enbridge was issued fully subject to the public trust, and the U.S. Supreme Court has held states have the power to resume the trust whenever the State judges best.  The state owes Enbridge nothing.  Enbridge owes the people of Michigan the respect they deserve by ending its efforts to skirt statutes and the public trust.”


A Clear Plan to Decommission Line 5

Advocates of shutting down dangerous Line 5 at the Straits of Mackinac presented a detailed plan for its decommissioning yesterday.  The plan gives the state officials who are accountable, Attorney General Bill Schuette and Governor Rick Snyder, a detailed, realistic plan for protecting the Great Lakes from a catastrophic oil spill while assuring energy to meet Michigan’s needs.
 
Enbridge has been using publicly-owned lakebed at the Straits as a conduit for its shipments of oil and gas underneath the Straits under a 65-year-old easement granted by the state on the condition that the company operates prudently.  But repeated disclosures of shoddy maintenance, structural flaws in the pipelines and concealment of critical information from state officials demonstrated Enbridge is not acting prudently.
 
FLOW Executive Director Liz Kirkwood said, “It’s time to move forward with legal action to compel strict enforcement of the current easement and to set a timetable for ending the easement.”

Liz Kirkwood’s Comment to the PSAB

  • Over two years ago, the Governor of Michigan created this Advisory Board by Executive Order to “Review and make recommendations for statutory, regulatory, and contractual implementation of the Michigan Petroleum Pipeline Task Force Report.”  This meant the board was required to oversee an independent and comprehensive analysis of risks and alternatives. 

 

  • Instead we Michiganders have (1) no risk report, (2) a flawed alternative report that still ignores the most credible alternative – using existing and expanded pipeline infrastructure around the Great Lakes, and (3) the Governor’s Thanksgiving deal with Enbridge that locks in a tunnel alternative under 20 percent of the planet’s fresh surface water. 

 

  • What our leaders have now is Tunnel Vision. 

 

  • Tens of thousands of citizens of this state have taken the time to study these matters and express their views to you.  Members of this board have spent countless hours on your task.  All of that for naught because of a closed-door agreement between Enbridge and the governor.

 

  • The deal allows Enbridge’s decaying Line 5 oil pipelines to continue to occupy the publicly owned lakebed at the Straits of Mackinac indefinitely, despite the company’s record of deception, poor stewardship, and bungled emergency response.  It’s a reward for failure.

 

  • We know a fair alternative analysis can be done.  In fact, in December 2015, FLOW offered a thorough analysis for the decommissioning of Line 5 that established an alternative that reasonably met the basic purpose of transporting crude oil to the various refineries within and beyond the Great Lakes region.  Why hasn’t the state done the same?

 

  • The Governor’s deal has mapped a blueprint that narrows the alternatives to some form of tunnel replacement in the Straits, the Great Lakes, and St. Clair River.  Moreover, the deal will bind the state to a new replacement of the entire 645 miles of Line 5 through Michigan and potentially open the door to heavy tar sands.

 

  • In the interest of full transparency and public knowledge, this board can do the people of Michigan a service by asking for a full public accounting for this deal, and by demanding a credible adverse weather provision to shut down Line 5 and a comprehensive alternatives analysis as required by law. The future of Line 5 is about the future of the Great Lakes.  And fortunately, public trust law makes this the public’s decision, not a closed-door deal between the Governor and Enbridge.     

 

Thank you.

Liz Kirkwood, Executive Director


 

Failed Leadership and Line 5


Our State’s leadership in the handling of Enbridge’s Line 5 in the Straits of Mackinac has gone from bad to worse. In light of disclosures by Enbridge of a failed pipeline design and the refusal on the part of our State leaders to take action to prevent devastating harm to the Great Lakes, it is time for leaders to either step up or step aside and let the voters or courts decide.

Enbridge has revealed previously withheld documentation showing bending of pipelines from extreme currents, delaminating protective cover, and numerous sections of bared steel open to corrosion. What Enbridge doesn’t understand is this: The State is trustee for citizens who are legally recognized beneficiaries of the public trust in the Great Lakes. The State trustee has a duty to prevent unacceptable harm or risks to the Great Lakes and the boating, fishing, swimming, and drinking water that depend on them. The decision does not belong to Enbridge but to our State’s leaders as trustees of these public paramount waters. Risk is a function of magnitude of harm; the higher the harm, the greater the risk. So it doesn’t matter what Enbridge executives think or say, or what their studies say after consultants have admitted conflicts of interest and withheld critical information on the failed condition of the lines.

Our State’s leaders must put an end to this now. Statements by Governor Snyder, DEQ Director Grether, and Attorney General Schuette about “serious concern” or “disappointment” do not go far enough. The proper response to the serious risk of unthinkable harm to the Straits and Great Lakes is not mere feeling; it is leadership and action. Governor Snyder’s recent agreement has belied even his disappointment. He expressly short circuited the his own advisory board and a citizen process established by his own Executive Order. The agreement expressly narrows a comprehensive alternative study to find a way to avoid crude oil pipelines in the Great Lakes, by expressly agreeing to a replacement of Line 5 in the Straits of Mackinac and the St. Clair River. So much for disappointment, he’s handing Enbridge a large Christmas present.

The Governor and DEQ should have required Enbridge to prove that there is no alternative to crossing under the Great Lakes for pipeline transport to Canada. It is unlikely Enbridge could prove that a non-Great Lakes pipeline alternative does not exist, given the fact that Enbridge recently doubled its design capacity in Line 6b across southern Michigan to Sarnia from 400,000 to 800,000 barrels. To win approval from the Public Service Commission to double its capacity across southern Michigan after the Kalamazoo disaster, Enbridge repeatedly testified if approved the doubled capacity would fulfill the company’s current and future needs, as well as those of Canada and the smaller needs of Michigan.

Our leaders must suspend the transport of crude oil through Line 5, and order Enbridge to start over by revoking the easement the state granted in 1953 and making the company comply with the laws and public trust that protect the Great Lakes. A bank trustee would have been replaced a year ago for such inaction as our state’s. If our leaders, the sworn trustees of our Great Lakes, don’t take action, they, too, should be replaced. Hopefully, it won’t come to that. If it does, then our third branch of government—the courts—should step in as they would in a receivership where management has failed.

It will not have to come to this if our leaders put a stake in the ground and suspend transport of oil. It will finally after three years of “cat and mouse” place the burden where it belongs: on Enbridge. Enbridge must be forced under rule of law to prove no catastrophic harm or acceptable risk and that it has no alternative to a pipeline in the Great Lakes. The truth is Line 5 under the Straits violates “reasonably prudent person” standard in the Easement, a common sense covenant that the company agreed to when it was granted the 1953 easement. It is no longer prudent to risk the Great Lakes with a crude oil spill of tar balls, dead fish, and oily wildlife and beaches.

The message and course of action for our Great Lakes State leaders is clear: Step up or step aside. If not, the courts or voters will do it for you.


Flint and the Straits of Mackinac

What do the Flint drinking water catastrophe and the recent agreement regarding the Enbridge pipeline at the Straits of Mackinac have in common?  Both are the result of a gubernatorial administration with fundamental mistrust of the public it serves.

In Flint, the Snyder Administration appointed an emergency manager to short-circuit democratic processes and act paternally on behalf of a community it deemed incapable of self-government.  The result was appalling damage to the health and well-being of the community.

This week, the Snyder Administration appointed itself emergency manager of the imminent danger posed to the Great Lakes by Enbridge, apparently deciding the public, the Governor’s own Pipeline Safety Advisory Board, and the DEQ under the State’s Great Lakes protection laws were incapable of contributing to a rational decision.  Astonishingly, the public engagement process the Governor himself set in motion with an executive order more than two years ago was essentially discarded in favor of a pact secretly negotiated with Enbridge.  The thousands of people and hundreds of organizations and communities who took the time to comment on the future of the pipeline were ignored in favor of assurances from a company responsible for the worst inland oil spill in U.S. history.

Democracy and public participation are under attack at many levels, and the result is poor public policy. The Governor’s agreement with Enbridge puts the Great Lakes at risk.


Pitting Corrosion and the Impact of Zebra and Quagga Mussels on Bare Steel Pipelines

FOR IMMEDIATE RELEASE TO MEDIA: November 3, 2017

Portions of the steel oil pipelines in the Mackinac Straits may have lost half their wall thickness since installation in 1953 and become dangerously weakened due to hard-to-detect pitting corrosion, an engineering expert said today.

The independent analysis further strengthens the case for an immediate shutdown of Line 5 to prevent a catastrophic oil spill in the Great Lakes, according to FLOW, a Great Lakes law and policy center based in Traverse City. The full analysis can be found at www.FLOWforWater.org.

The possible damage stems from invasive zebra and quagga mussels that have covered portions of the dual underwater pipelines for years, inhibiting external inspection of Line 5 while possibly weakening the steel.

“The cause of their corrosiveness is the excrement from the mussels, which is acidic. An acidic deposit on bare steel leads to corrosion,” said Gary Street, MS, PE, the former director of engineering at Dow Environmental who conducted the analysis. Street notes that pipeline inspection tools called “smart pigs,” which Enbridge uses to detect corrosion, are not very accurate in detecting pitting corrosion.

The disturbing possibility of a significantly weakened Line 5 in the Mackinac Straits comes after recent acknowledgement by the pipeline owner and operator, Enbridge, that there are several large areas of the pipeline where the protective coating is missing. According to Enbridge, the bare steel on Line 5 in the Mackinac Straits was detected by Canadian oil transport giant Enbridge in 2014 when the company installed more supports, but not revealed to regulators until this summer.

“What else is Enbridge hiding from the public and state regulators?” asked Liz Kirkwood, executive director of FLOW and an environmental lawyer. “Attorney General Bill Schuette must immediately enforce the laws protecting the Great Lakes and revoke the state easement that has allowed a private Canadian company conditional use of our public waters and bottomlands.”

Not all types of corrosion are equally harmful. Some forms are far worse than others. Pitting corrosion is a localized form of corrosion by which tiny cavities or “holes” are produced in the material. The National Association of Corrosion Engineers has stated, “While corrosion of bare steel can take many forms, the most insidious, is pitting corrosion.”

“The prudent scenario is to assume that damage originally occurred in 2003 when the first of the new supports was installed,” said Street, whose 35+ year career in industry and consulting has covered an extensive range of experience in environmental engineering, chemical process design, ethanol production processes, minimization of waste materials, project management, and engineering management. “That being the case, it is very possible that the Line 5 pipe wall has suffered serious pitting corrosion beginning at that time. Making the matter worse, pitting corrosion is very difficult to detect.”

Enbridge acknowledged the areas of external anti-corrosion coating loss in September. Several of the areas are larger than the “Band-Aid“-sized areas Enbridge initially described when the gaps were revealed. The largest patch of exposed pipeline metal is 16 inches long and 10 inches wide. Others are narrower but also exceed a foot in length.

Also detailed in the Enbridge reports is a “disturbed” coating area that’s more than 3 feet long, a “dislodged” coating area that’s 13 feet long and a mysterious 8-inch “white deposit” of unknown origin that Enbridge says “remains under investigation.”
