XL Pipeline Nightmare

This map shows both existing and proposed Canadian and U.S. pipelines that carry tar sands oil, including controversial Keystone XL Pipeline.

This is Part 1 of a 2-part Series

(See Part 2 here: A Cautionary Tale—Tar Sands Oil and Health)

Debate continues to rage over whether the Obama administration should approve TransCanada Corporation’s contentious Keystone XL pipeline.

Meanwhile, little attention has focused on the impact of tar sands oil spills in far-flung states. Two accidents, in Arkansas and Michigan, raise largely unaddressed questions about the true cost to human health and the environment—and the high cost and difficulty of cleanup. But there are other issues as well, ranging from the political and economic impact to the behavior of the corporations involved to the very nature of the substance itself.

mayflower_tar_sands_oil_spill_EPAPipe Dreams—or Nightmares?

The more recent of these disasters came on March 29, when a 22-foot gash opened in ExxonMobil’s 65-year-old Pegasus pipeline. It dumped some 210,000 gallons of tar sands oil into the streets of Mayflower, Arkansas, and into nearby Lake Conway.

More than six months after that lake of viscous tar sands crude engulfed a subdivision, many homes—both within the core spill area and at the periphery—stand deserted.

Among the few inhabitants who remain are those too old or too poor to leave, while many others simply have no place else to go. The streets are dotted with For Sale signs that beckon no buyers. Many people are ill, suffering from respiratory problems, chronic headaches, debilitating fatigue and other complaints.

Environmental scientist Wilma Subra says the symptoms are consistent with known effects from exposure to petroleum products—and to the volatile chemicals used to dilute the gummy Canadian oil so it can flow through a pipeline.

While cleanup continues, the legal battles have just begun. Among them are class action and civil suits, plus a lawsuit filed by the US Justice Department and the state of Arkansas for alleged violations of state and federal environmental laws, including the Clean Air and Clean Water Acts.

ExxonMobil Lied About What Spilled

For weeks after the spill ExxonMobil withheld crucial information about the nature of their product from state and local officials. The oil giant insisted it was conventional crude—which is cheaper and easier to clean up—while downplaying the amount and extent of contamination. Early on, company officials claimed that nearby Lake Conway was oil-free—though internal emails showed that they knew otherwise.

The March 2013 Exxon Tar Sands Spill in Mayflower, Arkansas

A Billion Dollar Spill?

Far to the north, 40 miles of Michigan’s Kalamazoo River shimmer with a slick rainbow sheen. It’s the toxic legacy of the largest, most expensive onshore oil spill in US history.

On July 26th, 2010, Enbridge Energy’s “Line B” pipeline ruptured, belching over a million gallons of tar sands oil into a field near Marshall, Michigan. Some of that flowed into nearby Talmadge Creek and on into the Kalamazoo—sites of previous industrial dumping and heroic cleanup efforts.

Three years later, so much heavy Canadian crude still coats parts of the river bottom that last March, the  the U.S. Environmental Protection Agency (EPA) ordered Enbridge to resume dredging the river.

The agency estimates that perhaps 180,000 gallons remain submerged, “plus or minus 100,000 gallons.” Federal fines of $3.7 million pale beside actual cleanup costs, which now exceed a billion dollars.

Enbridge contends it spilled a mere 843,000 gallons—although EPA evidence shows far more. The company waited a week to disclose that the spill was not ordinary oil, but instead thick tar sands oil. Some 320 people have reported health problems, and litigation is ongoing in a host of lawsuits.

Capture2Oil and Water…

Even these accidents, however awful the consequences for local residents, fail to paint a picture of the potential for catastrophe in the Keystone XL Pipeline project.

If completed, this pipeline would funnel nearly 35 million gallons of Canadian tar sands oil—a day—from Alberta to Texas Gulf Coast refineries.  Along that 1,179-mile route, the line would cross six states in America’s heartland, and traverse the Ogallala Aquifer that provides drinking water for two million people.

Though the location of oil and gas pipelines is public information, neither TransCanada nor the State Department has revealed Keystone XL’s exact route. But the general path is clear. Keystone will cross a remarkable 1,748 bodies of water in all, including the Yellowstone and Missouri Rivers.

In an accident, numerous toxic chemicals would be released, including benzene, a known human carcinogen. One at-risk ecosystem, Nebraska’s fragile Sandhills region, lies along the Keystone route, with ancient dunes so permeable that nearly 100 percent of rainfall enters the shallow Ogallala Aquifer. This means that a relatively minor spill can have major consequences.

***

While spills are the most immediate threat posed by the pipeline, much of the Keystone debate has focused on climate change. NASA climatologist James Hansen has called Canadian oil sands crude “one of the dirtiest, most carbon-intensive fuels on the planet.”

How bad? It emits 14 to 20 percent more greenhouse gases than conventional crude, according to a congressional report. But the environmental group Rainforest Action Network (RAN) says it’s much, much worse:

Tar sands oil is the worst type of oil for the climate, producing three times the greenhouse gas emissions of conventionally produced oil because of the energy required to extract and process tar sands oil. . . increased greenhouse gas emissions associated with tar sands development is the main reason Canada will not meet its Kyoto reduction commitments.

Tar Sands Toxic WasteOil or “Molasses”

Tar sands oil should not be confused with conventional crude. Alberta’s oil is a gelatinous mix of tarry petroleum and sand, known as diluted bitumen or “dilbit.” It’s often likened to asphalt: it is so thick and gooey that it won’t flow through a pipeline on its own. For transport, it’s thinned with liquefied natural gas and a range of chemicals, some of which are extremely toxic.

It’s far stickier than other petroleum products—and it sinks in water, which is why oil sands spills are extremely difficult to clean up, said Stephen K. Hamilton, a Michigan State University aquatic ecology professor who’s advising the state and the EPA on the cleanup in Marshall. “The bitumen reverts to its molasses-like nature once the diluent evaporates, and is nearly impossible to remove from surfaces…and river banks,” he said. “The EPA estimates that a significant fraction of the spilled oil remains in the sediments even after all the time and money invested in cleanup, and I am sure we will never get it all out.”

pegasus-oil-spill-arkansas-exxonDirty Oil, Dirty Politics

Legally, bitumen is not even considered oil. In 2011, the Internal Revenue Service (IRS) ruled that “the term ‘crude oil’ does not include “synthetic petroleum.” That distinction exempts Enbridge, ExxonMobil, TransCanada and other companies that transport tar sands crude from paying the 8-cents-per-barrel petroleum excise tax. Thus, the companies shipping a substance that’s more toxic and harder to clean up than standard petroleum products do not even have to pay into the Oil Spill Liability Trust Fund, which was created by Congress in 1986 and enacted four years later in response to the Exxon Valdez disaster.

Cleanup of the massive Deepwater Horizon oil spill and a host of smaller accidents drained the fund to risky levels, according to a Government Accountability Office report. As of March 2011, the fund had shelled out $629.5 million for Deepwater. Liability for oil companies caps at $350 million; the fund covers the rest, up to a billion dollars per incident.

But tar sands oil gets a free ride, with transport companies putting nothing aside to help pay for pipeline breaks or other accidents.

The House Natural Resources Committee criticized the exemption, noting that “it is important that all oil companies be held responsible for the disasters associated with the products they sell and the taxpayers not be forced to pay the bills of cash rich oil companies.”

Indeed, keeping the exemption in place through 2017 would mean $409 million in lost revenue. With skyrocketing dilbit imports from Canada, it’s no small concern. The 220,000 barrels (42 gallons each) imported per day in 2000 jumped to over 650,000 barrels in 2011.  Producers hope to top 1.5 million barrels in the next six years, according to Canada’s National Energy Board. A series of major spills could bankrupt the fund—leaving taxpayers with a massive cleanup bill.

TransCanada’s environmental assessment estimated that Keystone XL will discharge 11 “significant” spills of 2,100 gallons or more in the US over its 50-year lifespan. An independent analysis by Dr. John Stansbury, an engineer and professor at the University of Nebraska, presents a far more alarming scenario: up to 91 serious spills over that same period. His study includes key data omitted by TransCanada.

largeA Hazard to “Life, Liberty, and the Environment”

Pipelines break for many reasons, from advancing age and weak welds to natural disasters and construction accidents. But transporting heavy, toxic dilbit further increases stress on pipelines, according to a recent Cornell University study.

It’s 15 to 20 times more acidic than conventional heavy crude, with five to 10 times more sulfur. Because it’s so thick, it’s often pumped at higher temperatures and pressures than other petroleum products. Its varying composition and consistency bring large, frequent swings in pressure that can create new cracks or widen existing ones—a factor that may have played a role in ExxonMobil’s Arkansas break.

And that was no isolated case. From 2007 to 2010, dilbit pipelines in the northern Midwest dumped three times more oil per mile than the national average for conventional crude. Since the Keystone’s Phase 1 pipeline opened in June 2010, there have been at least 35 incidents. It pumps dilbit from Alberta to refineries in Illinois, a line that breezed through the permitting process during the Bush Administration, with little public awareness.

The string of accidents prompted pipeline safety regulators to subsequently deem Keystone 1 a hazard to “life, property, and the environment”—and issue a “Corrective Action Order” to address multiple problems.

oilincreek “A Complete Breakdown of Safety”

Regulators realized in the late 1990s that pipeline operators were losing control of their systems, says Richard Kuprewicz, president of the engineering consulting company Accufacts, Inc. and adviser to the U.S. Pipeline and Hazardous Materials Safety Administration (PHMSA). Minimum safety guidelines were updated back then, but now, he says, “we’re seeing a rash of ruptures.There’s no doubt that there’s something wrong with current pipeline safety regulations.”

In a recent speech to oil and gas pipeline compliance officers, PHMSA associate administrator Jeffrey Wiese admitted that the regulatory process he oversees is “kind of dying” and that his office has “very few tools to work with” in enforcing safety rules. “Do I think I can hurt a major international corporation with a $2 million civil penalty? No,” he said.

Before they failed, both the Mayflower and Marshall lines were known to have developed cracks. The defect that caused the six-and-a-half-foot hole in Enbridge’s Line 6B was noticed at least three times, but both regulators and the company ignored it. Likewise, ExxonMobil Pipeline Co. inspected the section of Pegasus that later burst in 2010 and again in early 2013. But again, nothing was done.

At a hearing on the Michigan spill in 2012, National Transportation Safety Board chairman Deborah Hersman stated, “This investigation identified a complete breakdown of safety at Enbridge,” and likened employees’ poor handling of the rupture to “Keystone Kops.”

Despite numerous alarms it took operators in Michigan nearly 12 hours to shut down the 30-inch wide pipeline. Another six hours passed before they located the spill site.

The transportation safety board also cited weak federal regulation and oversight of emergency procedures, and poor assessment and repairs of pipeline health.

Fast-Tracking the Pipelines

While TransCanada awaits a decision on Keystone XL, it’s unclear whether Exxon’s 858-mile Pegasus pipeline will reopen. The company hasn’t made public its plans for the line, which will require written permission from PHMSA to restart. Analysts conjecture that Pegasus may be in such poor shape that it will need significant repair—or that Exxon may be weighing construction of a new, larger replacement.

But other lines will soon be shipping tar sands products to the Gulf for refining and export. Enbridge plans to expand its Alberta Clipper pipeline from Canada to Wisconsin, which would carry up to 880,000 barrels a day, more than Keystone’s planned 830,000-barrel capacity.

The company’s 774-mile Trunkline is scheduled to go into operation in 2015, using converted gas lines that run from Patoka, IL, to St. James, LA. There is concern that these lines, which have been in the ground for years, were not built to current standards and may not be able to withstand the heavier load of tar sands oil. But these conversions are subject to fewer regulations and generally win swift approval.

***

The safety issue clearly gets short shrift. PHMSA, the entity charged with oversight, has been understaffed by an average of 24 employees each year between 2001 and 2009. And last year, it had funding for just 137 inspectors in total. That’s nowhere near enough to police the industry.

As a result, regulators are forced to essentially leave safety evaluations up to the companies–even allowing them to plan their own future pipeline routes. The two assessments submitted for Keystone XL were prepared with blatant conflicts of interest: one by a former client of TransCanada, and the second by a member of the American Petroleum Institute, the oil and gas industry’s largest U.S trade association. The EPA commented that the documents lacked needed information on water protection and an improved emergency response plan.

Americans Don’t Even Gain

Americans risk environmental catastrophe while gaining…next to nothing.

As the Rainforest Action Network notes:

Keystone XL is an export pipeline. In presentations to their investors, Gulf Coast refiners have revealed plans to refine Keystone’s Canadian crude into diesel and other products for export to Europe and Latin America. Proceeds from these exports are earned tax-free. Much of the fuel refined from the pipeline’s heavy crude oil will never reach U.S. drivers’ tanks.”

(More on this point from the environmental advocacy group Oil Change International, here.)

With Liberty and Justice for…Oil

The pressure from industry has been considerable. With well-funded publicity campaigns promoting “energy independence,” it’s not so surprising that in March 2012, President Obama signed an executive order expediting infrastructure permits that will fast-track oil and gas pipeline projects.

One of the loudest arguments for Keystone XL approval is job creation—a projected 20,000 construction and manufacturing jobs, according to TransCanada. But the Cornell Global Labor Institute examined their data and came up with a far lower estimate: somewhere between 2,500 and 4,650 temporary, direct jobs would come from pipeline construction over a two-year period.

In fact, the U.S. State Department estimates that the six states along the pipeline route will gain a total of just 20 permanent pipeline operation jobs. Meanwhile, with 571,000 agricultural workers employed in those states, a spill that poisons farmland and ground water could mean a significant economic hit, not to mention the potential harm to the region’s substantial tourism industry (which in South Dakota alone brings in $865 million a year).

If Obama is under pressure to hand the industry another fortune, imagine the pressure the Canadian leadership faces. Evidence of this was on display during a late September visit to New York City by Canada’s Conservative Prime Minister, Stephen Harper. In an unusually pugilistic stance for a Canadian, Harper declared that he “won’t take no for an answer” from his much larger neighbor to the south.

“The logic behind this project is simply overwhelming,” he said.  And he added (apparently drawing another bloated figure out of the north-of-the-border air), it “will create 40,000 jobs in the U.S.” His incentive to sell the project is clear enough: Canada’s share of U.S. crude oil imports rose to 38.7 percent in February, the highest in at least two decades, according to U.S. Energy Information Administration data.

PipelineSpillAftermathinArkansas060513

As Kuprewicz, the engineering consultant, notes: “We’re not going to get rid of oil and gas pipelines, so we need to operate them safely.” But the question remains: Is shipping more tar sands oil into the US the wisest choice?

    This is just one more in a long list of examples of how government subsidizes big business. People don’t seem to care as long as the promise of jobs is dangled out in front of them. Nuclear energy is the same. It wouldn’t be even remotely profitable if not for government massively subsidizing its liability exposure to any accidents, as is now all too clear from Fukushima. ( see here: http://www.iisd.org/gsi/news/fukushima-disaster-puts-focus-hidden-subsidies-nuclear-power-0 )

    Interestingly enough, one of the main beneficiaries from the delay in the XL pipeline has been Warren Buffett thanks to the extra demand it has created for rail transportation of oil in its place.
    ( see here: http://www.bloomberg.com/news/2012-01-23/buffett-s-burlington-northern-among-winners-in-obama-rejection-of-pipeline.html )

    If we ended these kinds of subsidies and companies then had to bear these additional environmental costs, these costs would be in turn passed on to consumers in the form of higher prices no doubt. But that’s only part of the story. This would also create an enormous incentive for companies to find ways to become leaner and cleaner, so in the long run it can be win-win. The energy business is moving in this direction anyway, but much more slowly than would otherwise be the case if these subsidies didn’t exist.

  • Anita Patel

    Doesn’t it make more sense to move the refinery to Alberta rather than piping the viciously toxic product nearly 1200 miles to a US refinery? It is bad enough that the sociopathic titans of the oil industry are exploiting tar sands without then needlessly exposing so many vulnerable and fragile environmental systems to the inevitable “accidents” their madness will engender. If they must deal in filth then at least keep it all in one place. Pollute Alberta not the US.

    • jsmith

      You know, I never thought of this. Why not build a refinery at the source, but of course Anita.

    A 65 year old pipeline!! Lol. That’s the real criminal here you guys. That’s quackery that this line is still in production. These lines in canada here at least are constantly being smart pigged to insure the lines integrity. And repair work in canada is continuos. Because of the sand in bitumen it wears the bottom of the pipeline out so it always needs to be maintained. There should be stringent laws in place of smart pig frequency. Where’s the oversight!!! And who s enforcing it. This is such a corrupt system.

    What a world it would be without Exxon, Mobil, Shell, BP. They became obsolete “useless eaters” well before WWII. Between the power of petroleum corporations and the Goldman Sachs enriching themselves on heroin sales, laundering the billions from Afghani “warlords” and stealing your retirement fund the middle class American is now a corporate slave.

    • Sharon Guynup

      You’re right–Valdez was in ’89. The fund was created in ’86, but no monies were collected or used until it was enacted in 1990 in response to the spill. Will tweak that point, thanks for your careful eyes!

    Not that it changes anything in the debate, but Canada doesn’t have a “much larger neighbor to the south”. Canada is bigger than the US, not by much, but it’s definitely bigger in land and natural resources.

  • Troy

    The reasons for not refining the oil in Alberta is a need for water apparently? Although that claim is hard to believe as Canada is flush with water? There is real talk about refining the oil on Canada’s west coast, there are greedy reasons why it’s preferred to ship the raw product to “other” destinations for refinement . Canada and the USA need to start acting like nations and look after each other like the brothers we are and our personal national interests, our future is being exported for the gain of our rivals!
    Historically such bending to the will of foreign corporations would have been labelled treason would it not?

  • save mother earth

    there are just to many dangers involved such as natural
    disasters being tornadoes, undetected oil leaks, unstable
    geological areas even a possibility of destabilizing tectonic
    plates causing earthquakes. Poisoning the water aquifers
    is real and possible. wouldn’t it just be easier to pipeline it
    in canada than going across the united states. who is the
    oil going to anyway? Is it going to be a reserve build up for
    american oil reserves or just put on the world market. I
    don’t believe americans will benefit from this pipeline and
    there are just too many hazardous risks involved.

    If all the costs of fossil fuels were built into the price paid at the pump the focus would be on clean renewables and there would be a leap in technology and solutions. That is the issue. Viable alternatives must be the focus. Climate change and pollution is a near term crisis.
