Residents of Mayflower, Arkansas, are suing ExxonMobil for damages in a class action lawsuit that is seeking more than $5 million in compensation for property damage.

"This Arkansas class action lawsuit involves the worst crude oil and tar sands spill in Arkansas history," the lawsuit reads. The filed claim indicates more than 19,000 barrels of oil were spilled.

Both the Attorney General Dustin McDaniel and the US Department of Transportation's Pipeline and Hazardous Material Safety Administration (PHMSA) have indicated investigations into the pipeline rupture are ongoing.

Between 2010 and 2012, pipeline incidents incurred more than $662 million in property damages annually. More than 20 years of PHMSA records indicate levels of pipeline related accidents are consistent – around 250 occur each year – while the cost of those accidents is steadily increasing.

These recently released images show the scope of the damage has grown far beyond the nearby residential street:

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.

There has been a marked boost in the rail transport of crude in the last three years as new extraction techniques increase production in the tar sands. According to Reuters, “U.S. trains carried 233,800 carloads of crude oil in 2012, more than double the 65,800 carloads transported in 2011 and dwarfing the 29,600 in 2010, according to figures from the Association of American Railroads.”

Meanwhile the Canadian Pacific Railway’s crude oil volumes have skyrocketed from 2,800 carloads in 2010 to a staggering 53,000 last year. The company hopes to increase that number to over 70,000 this year.

Most, if not all, advocates of pipeline transportation will argue that the growing use of rail transport emphasizes the urgent need for pipelines. Pipelines are commonly touted as a more reliable mode of fuel transport than rail.

Pipelines, as the story goes, are safe.

Unfortunately for pipeline proponents, last week’s pipeline rupture in Arkansas is no anomaly in the history of US pipelines. In fact, pipelines have made a pretty consistent mess throughout the States for the last 20 years. One thing has changed, however: those messes are getting more expensive to clean up.

The U.S. Department of Transportation’s Pipeline & Hazardous Materials Safety Administration (PHMSA) is responsible for reporting and recording all “significant pipeline incidents” which are all incidents exceeding the cost of $50,000 (in 1984 dollars).

In terms of property damage PHMSA records indicate that the 20-year average (1993-2012) cost of significant pipeline incidents is over 318 million dollars, the 10-year average (2003-2012) cost is over 494 million dollars the 5-year average (2008-2012) cost is over 545 million dollars and the 3-year average (2010-2012) cost is over 662 million dollars.

The cost of cleaning up after pipelines just keeps getting more expensive.

Over the last 20 years, pipeline incidents have caused over $6.3 billion in property damages. On average during this time period there were more than 250 pipeline incidents per year, without a single year where that number dropped below 220. During that time, more than 2.5 million barrels of hazardous liquids were spilled and little more than half of those spilled amounts were recovered in cleanup efforts.

One of the factors contributing to the cost of cleanup is the introduction of Alberta’s diluted bitumen to southern markets (The most expensive year on record is 2010 when Enbridge spilled 3.3 million liters or 877,000 gallons of dilbit into Michigan’s Kalamazoo River).

Companies eager to move Canadian dilbit south to refineries and export facilities have been jimmying an aging pipeline infrastructure to handle the more corrosive substance and there is currently no federal oversight to monitor this process.

ExxonMobil’s sixty-five-year-old Pegasus pipeline that ruptured last week was one such retrofitted line. Built in the late 1940s, the old winged horse of a pipeline was reversed in 2006 in order to carry Canadian dilbit to the Gulf Coast via Illinois at a 50 percent increased capacity. The burst line sent a river of at least 84,000 gallons of dilbit running down residential streets in Mayflower and into nearby wetlands. 

The exact cause of the pipeline rupture is still unknown.

Many of the major pipeline operators – like Exxon, Enbridge and TransCanada – have been cited for lax inspections, shoddy emergency preparedness, and ineffective spill management and response. Both Exxon and Enbridge have been told their actions in the immediate hours after pipeline ruptures have made spills worse than necessary.

NPR reports “more than half of the nation’s pipelines were built before 1970. More than 2.5 million miles of pipelines run underground throughout the country.”

Debbie Hersman with the National Transportation Safety Board told NPR, “100 percent of the accidents that we’ve investigated were completely preventable.” In many cases companies performed inspections and discovered cracks and corrosion in the line but did not perform repairs before accidents occurred.

In an interview with Reuters, John Stephenson, vice president and portfolio manager at First Asset Investment Management in Toronto described these events as “not good for producers…not good for Canadian oil going south…not good for Keystone.”

But added, “the reality is this oil is going to make it south of the border, quite likely by rail or one of the other pipelines across the Canadian-US border, so I see it as a short-term hiccup at worst.”

Yet even a cursory glance at the history of pipeline accidents in the US shows what is happening in Arkansas is no ‘hiccup’ and will bear no ‘short-term’ consequences. At least, not for the residents of Mayflower.

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.

The Pegasus pipeline was built in the 1940s to carry regular crude north from the Gulf Coast. In 2006, Exxon reversed the flow of the 1300 kilometre line in order to transport tar sands diluted bitumen from Illinois to the coast.

According to the Natural Resources Committee, "the spill response fund is currently at risk from running out of money because of the combined costs of BP's Deepwater Horizon spill and Enbridge's Kalamazoo spill of tar sands oil…And Enbridge could still file a claim against the fund to recoup some of its costs because the company has spent well over the liability cap of $350 million for such spills."

The Enbridge disaster in Michigan's Kalamazoo river has cost over $820 million, making it the most expensive onshore cleanup in US history.

Enbridge, the company currently vying to build a 1172 kilometre-long pipeline from Alberta to the British Columbia coast, currently has no spill-response plan – for either onshore or offshore spills – prepared for the project.

During cross-examination in the Northern Gateway Pipeline hearings in BC, Enbridge admitted they will have no spill response plan until six months before the proposed tar sands line will begin operation. 

An investigation in the Enbridge Kalamazoo disaster found the company – due to "pervasive organizational failures" – improperly respond to the pipeline breach. The US National Transportation Safety Board likened Enbridge employees to the Keystone Kops – a clumsy, incompetent troups of cops from the silent films of the early 20th century.

The estimated cleanup cost for conventional oil run at about $2000 per barrel of oil. Tar sands diluted bitumen cleanup is estimated to cost an average $29,000 per barrel of spilled oil.

The Oil Spill Liability Trust Fund was established in the wake of the Exxon Valdez oil spill, when the enormous costs of oil spill recovery were first understood on a grand scale, to ensure adequate cleanup funds were available to protect local residents and ecosystems.

As Climate Progress reported in 2010, Exxon refused to shoulder the cost of cleanup in the Valdez, where more than 11 million gallons of crude oil contaminated almost 3000 kilometres of shoreline.

"Exxon fought paying damages and appealed court decisions multiple times, and they have still not paid in full. Years of fighting and court appeals on Exxon’s part finally concluded with a U.S. Supreme Court decision in 2008 that found that Exxon only had to pay $507.5 million of the original 1994 court decree for $5 billion in punitive damages. And as of 2009, Exxon had paid only $383 million of this $507.5 million to those who sued, stalling on the rest and fighting the $500 million in interest owed to fishermen and other small businesses from more than 12 years of litigation.

Twenty years later, some of the original plaintiffs are no longer alive to receive, or continue fighting for, their damages. An estimated 8,000 of the original Exxon Valdez plaintiffs have died since the spill while waiting for their compensation as Exxon fought them in court."

And as DeSmogBlog's Ben Jervey reports, Exxon has a long and litigious history of evading cleanup costs.

The US is facing a dramatic increase of tar sands oil imports. As the National Resource Committee estimates, production in the Alberta tar sands is projected to rise to over 2.7 million barrels per day in 2017. The tar sands industry projects figures as high as 5 million barrels per day in 2030 and 6 million per day in 2035. Currently approved projects have the capacity to produce 5.2 million barrels per day. 

“Tar sands is already the dirtiest, riskiest oil around. It shouldn’t get a free ride from the U.S. taxpayer when it comes to paying into this vital spill response fund,” said Rep. Markey, the Ranking Member of the Natural Resources Committee. “Oil companies already receive outrageous tax subsidies that total billions of dollars and there is no defensible reason for this oil spill free ride to be added to that dubious list of loopholes.”

Regardless of how many barrels of tar sands oil will be traversing US soil, none of them should be exempt from spill liability taxes. If anything, corrosive diluted bitumen should be taxed more for the inherent dangers it present to local ecologies and communities during its production, refining, and transport.

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.

Photographer Eilish Palmer, known as Lady with a Camera, has been working with HAWK (Helping Arkansas Wild Kritters), a wildlife rehabilitation centre, to locate and help ducks and other animals affected by the spill.

When I connected with Eilish on the phone today, she was outside in the rain searching for more oil-covered wildlife: "I'm actually out in the woods right now looking for animals. We just found two dead ducks and one live one…We actually saw a dead wood duck and we saw its mate, it couldn't fly away, only walk. It was pretty saturated." 

Eilish said HAWK was the first responder for affected wildlife in the area but has since seen Exxon establish a local mobile unit to treat animals on site. "As the number of animals increased Exxon brought in their own rehabilitation centre because we were taking the animals to a centre about an hour away. HAWK doesn't have a mobile unit."

In addition to ducks, the team working with HAWK also found this oil-laden male muskrat, suggesting a number of species may be affected.

Faulkner Country Judge Allen Dodson said "I'm an animal lover, a wildlife lover, as probably most of the people here are. We don't like to see that. No one does."

He added, "Crude oil is crude oil. None of it is real good to touch."

The Exxon spill leaked 80,000 gallons of oil into an Arkansas residential area, causing the evacuation of 22 homes. This weekend Exxon Mobil Pipeline Co. president Gary Pruessing told displaced homeowners, "If you have been harmed by this spill then we're going to look at how to make that right." 

According to InsideClimate News, Exxon is currently preventing the media from accessing the spill scene. Today the Arkansas Attourney General announced an investigation into the cause of the 60-plus-year-old pipeline's rupture. 

The Pegasus pipeline was originally built in the 1940s and was recently dormant for four years before its flow was reversed to carry Alberta diluted bitumen from Illinois to the Gulf Coast. In 2006, Exxon called the line's reversal a win-win for the people of the Gulf Coast and Canada.

The revelation that companies transporting diluted bitumen in the US have some concerned about pre-existing pipelines, as well as the proposed Keystone XL pipeline that will transport the tar sands-derived oil across a number of ecologically sensitive areas. 

According to the NRDC, in 2011 a number of pipelines carried Alberta bitumen in the US:

Although the spread of oil refineries across the US receiving bitumen suggests the network of tar sands oil transport is much more widely spread across the States:

The network potentially connecting bitumen-carrying pipelines with other pipelines is quite extensive across the US:

Last week a coalition of environmental groups, communities and inviduals petitioned the US EPA and Pipelines and Hazardous Materials Safety Association (PHMSA) to place a moratorium on pending tar sands pipelines, including the Keystone XL pipeline, until new safety rules are established. 

"Simply put, diluted bitumen and conventional crude oil are not the same substance," the petitioners wrote. "There is increasing evidence that the transport of diluted bitumen is putting America's public safety at risk. Current regulations fail to protect the public against those risks. Instead, regulations … treat diluted bitumen and conventional crude the same."
