Average 250 Pipeline Accidents Each Year, Billions Spent on Property Damage

If only this were milk there would be no need to cry.

Cleanup efforts are currently underway in four separate oil spills that have occurred in the last ten days.

On March 27th, a train carrying Canadian tar sands dilbit jumped the rails in rural Minnesota spilling an estimated 30,000 gallons of black gold onto the countryside. 

Two days later a pipeline ruptured in the town of Mayflower, Arkansas, sending a river of Albertan tar sands crude gurgling down residential streets. And news is just breaking about a Shell oil spill that occurred the same day in Texas that dumped an estimated 700 barrels, including at least 60 barrels of oil into a waterway that leads to the Gulf of Mexico (stay tuned for more on that).

This week a Canadian Pacific freight train loaded with oil derailed, spilling its cargo over the Northwest Ontario countryside. Originally reported as a leak of 600 liters, the CBC reported on Thursday that the estimated volume of the spill has increased to 63,000 liters.

The accelerating expansion of Alberta’s tar sands has North America’s current pipeline infrastructure maxed out and, as a result, oil companies have been searching for an alternative way to move their product to market. As lobbying efforts around the stymied Keystone XL and Northern Gateway pipelines intensify, oil companies have been quietly loading their toxic cargo onto freight trains.

Tar Sands Tax Loophole Cost US Oil Spill Fund $48 Million in 2012, Will Cost $400 Million by 2017

A tax loophole exempting tar sands pipeline operators from paying an eight-cent tax per barrel of oil they transport in the US is costing the federal Oil Spill Liability Trust Fund millions of dollars every year. With expected increases in tar sands oil production over the next five years, this loophole may have deprived US citizens of $400-million dollars worth of critical oil-spill protection funds come 2017.

According to a report by the US Natural Resources Committee the federal government pays for immediate oil-spill response from the Liability Trust Fund which is supported by an excise tax on all crude oil and gas products in the US.

But in 2011 the Internal Revenue Service exempted tar sands oil from the tax, saying the substance did not fit the characterization of crude oil.

This exemption has come under scrutiny this week after Exxon Mobil's Pegasus pipeline ruptured in Mayflower, Arkansas, releasing 300,000 litres of tar sands oil and water into a residential neighbourhood and surrounding wetlands. Because the line carried tar sands-derived oil from Alberta, Exxon was exempt from paying into the spill liability fund for the corrosive fuel's potential cleanup.

Because 'Bitumen is not Oil,' Pipelines Carrying Tar Sands Crude Don't Pay into US Oil Spill Fund

As Think Progress has just reported, a bizarre technicality allowed Exxon Mobil to avoid paying into the federal oil spill fund responsible for cleanup after the company's Pegasus pipeline released 12,000 barrels of tar sands oil and water into the town of Mayflower, Arkansas.

According to a thirty-year-old law in the US, diluted bitumen coming from the Alberta tar sands is not classified as oil, meaning pipeline operators planning to transport the corrosive substance across the US - with proposed pipelines like the Keystone XL - are exempt from paying into the federal Oil Spill Liability Trust Fund.

News that Exxon was spared from contributing the 8-cents-per-barrel fee to the clean-up fund added insult to injury this week as cleanup crews discovered oil-soaked ducks covered in "low-quality Wabasca Heavy Crude from Alberta." Yesterday officials said 10 live ducks were found covered in oil, as well as a number of oiled ducks already deceased.

Tar Sands South: First US Tar Sands Mine Approved in Utah

The race is on for the up-and-coming U.S. tar sands industry. To date, the tar sands industry is most well-known for the havoc it continues to wreak in Alberta, Canada - but its neighbor and fellow petrostate to the south may soon join in on the fun

On Oct. 24, the Utah Water Quality Board (UWQB) approved the first ever tar sands mine on U.S. soil, handing a permit to U.S. Oil Sands, a company whose headquarters are based in Alberta, despite it's name. 

In a 9-2 vote, the UWQB gave U.S. Oil Sands the green light to begin extracting bitumen from its PR Spring Oil Sands Project, located in the Uinta Basin in eastern Utah. The UWQB concluded that there's no risk of groundwater pollution from tar sands extraction for the prospective mining project.  

Members of the public were allowed to attend the hearing but "were not permitted to provide input," according to The Salt Lake Tribune

Must Read Muckrake on the Whistleblower Behind the Enbridge Tar Sands Pipeline Spill


On a midsummer evening in July of 2010, heavy crude started gushing from a 30-inch pipeline into Talmadge Creek, near Marshall, Michigan. By the next morning, heavy globs of oil soon were coating the Kalamazoo River, into which the Talmadge flows, and the stench of petroleum filled the air.

Enbridge, the Canadian company that owns and operates the ruptured pipeline 6B, made a lot of mistakes in the hours after the first gallons spilled. The disaster didn’t have to be so bad. Records of the official responses showed, for instance, that the company didn’t send someone to the site until the next morning. And that the Enbridge pipeline controllers increased pressure to the line, on a hunch that the funky signals they were getting was from a bubble, and not a spill.

When all was said and done, an estimated 1 million gallons of tar sands crude had leaked into the Kalamazoo River -- ranked by the EPA as the largest spill in Midwestern history -- with some oil flowing a full 40 miles down the river towards Lake Michigan.

Though the company that owns the pipeline, Enbridge, tried to deny it, the oil was soon revealed to be diluted bitumen (or DilBit), a form of tar sands crude that is thick and abrasive and can only be pumped through pipelines at enormously high pressure. DitBit is also, it turns out, much harder to clean up than regular old dirty crude. And that -- the clean up -- is where the story gets really complicated.

This week, OnEarth.org (where I’m also a blogger), published an incredible 3-part series about the Enbridge spill, the egregious mishandling of clean up efforts, and Enbridge’s deliberate cover-up of its shoddy, cheap, and reckless work. Written by Ted Genoways, who spent weeks on the ground in Michigan and accumulated over 100 hours of interviews, the piece is the sort of long form, old-fashioned, exhaustive muckraking that you don’t see nearly enough of these days.

The Many Problems With Tar Sands Pipelines

Enbridge tar sands pipeline spill Kalamazoo River Michigan

Note: This post is part of an ongoing series about North American pipelines. For an introduction and links to the wide-ranging coverage--from safety to legal issues to the business and economics to vulnerabilities--see this regularly-updated intro post.

On Monday, the House passed a bill that would force the Obama administration to make a final decision on TransCanada's controversial Keystone XL pipeline by November 1. The Keystone XL project (which regular DeSmogBlog readers should be familiar with) would funnel tar sands oil from Alberta's massive reserves down to Gulf Coast refineries in Texas.

This isn't the place to discuss in too much depth the various and plentiful problems with Alberta tar sands itself -- from extraction to transportation to refining to combustion, it's the dirtiest oil on the planet. From a climate perspective, the Alberta tar sands contain enough carbon to lock the planet into climate chaos. In the words of NASA climatologist Jim Hansen, "if the tar sands are thrown into the mix it is essentially game over."

Because Keystone XL is so controversial, and because its construction could be such a tipping point in the climate fight, a broad and diverse coalition of scientists and activists are digging in their heels for a big fight, and planning a multi-week action at the White House. (Here's more on how to get involved.)

But since this is a post about pipelines, I'm going to focus on how tar sands pipelines are different than those that carry conventional crude, how they're much more prone to leaks and spills, and how those spills are particularly bad for the environment.
