Permit Shows Bakken Shale Oil in Casselton Train Explosion Contained High Levels of Volatile Chemicals

On January 2, the Pipeline and Hazardous Materials Safety Administration (PHMSA) issued a major safety alert, declaring oil obtained via hydraulic fracturing (“fracking”) in the Bakken Shale may be more chemically explosive than the agency or industry previously admitted publicly.

This alert came three days after the massive Casselton, ND explosion of a freight rail train owned by Warren Buffett Burlington Northern Santa Fe (BNSF) and was the first time the U.S. Department of Transportation agency ever made such a statement about Bakken crude. In July 2013, another freight train carrying Bakken crude exploded in Lac-Mégantic, vaporizing and killing 47 people.

Yet, an exclusive DeSmogBlog investigation reveals the company receiving that oil downstream from BNSF — Marquis Missouri Terminal LLC, incorporated in April 2012 by Marquis Energy — already admitted as much in a September 2012 permit application to the Missouri Department of Natural Resources (DNR).

According to Marquis’ website, its Hayti, Missouri terminal receives seven of BNSF Direct’s 118-unit cars per week, with an on-site holding terminal capacity of 550,000 barrels of oil.

Marquis was one of many companies in attendance at a major industry conference in Houston, Texas in February 2013, called “Upgrading Crude By Rail Capacity.” Its September 2012 Missouri DNR permit application lends additional insight into how and why BNSF’s freight train erupted so intensely in Casselton.

“Special Conditions”

Rather than a normal permit, Marquis was given a “special conditions” permit because the Bakken oil it receives from BNSF contains high levels of volatile organic compounds (VOCs), the same threat PHMSA noted in its recent safety alert.

Among the most crucial of the special conditions: Marquis must flare off the VOCs before barging the oil down the Mississippi River. (Flaring is already a highly controversial practice in the Bakken Shale region, where gas is flared off at rates comparable to Nigeria.)

It’s a tacit admission that the Bakken Shale oil aboard the exploded BNSF train in Casselton, ND is prone to such an eruption.

“Hazardous Air Pollutant (HAP) emissions are expected from the proposed equipment,” explains the Marquis permit. “There will be evaporative losses of Toluene, Xylene, Hexane, and Benzene from the crude oil handled by the installation.”

Benzene is a carcinogen, while toluene, xylene and hexane are dangerous volatiles that can cause severe illnesses or even death at high levels of exposure.

Scientific Vindication

In a December 31 Google Hangout conversation between actor Mark Ruffalo, founder of Water Defense, and the group’s chief scientist Scott Smith, Mr. Smith discussed the oil samples he collected on a previous visit to North Dakota’s Bakken Shale.

“What I know from the testing I’ve done on my own — I went out to the Bakken oil fields and pumped oil from the well — I know there are unprecedented levels of these explosive volatiles: benzene, toluene, xylene,” said Smith.

“And from the data that I’ve gotten from third parties and tested myself, 30 to 40 percent of what’s going into those rail cars are explosive volatiles, again that are not in typical oils.”

In an interview with DeSmogBlog, Smith said Marquis Energy’s Missouri DNR permit application is in line with his own scientific findings, a vindication of sorts in the aftermath of the Casselton explosion.

“We must work to better understand the risks involved with the transportation of unconventional crude oil, whether diluted bitumen or Bakken fracked oil,” Smith told DeSmogBlog.

“It all starts with scientifically and transparently understanding exactly what is in these crude oils, and working to set new safety standards to protect human lives and all waterways, wetlands, marshes and sensitive ecosystems.”

It may be the dead of winter in North Dakota, but the Casselton explosion has shined a bright light on the myriad serious threats of Bakken oil rolling down the tracks through the backyards of thousands of Americans. The industry’s secrecy about the explosiveness of this oil just went up in flames.

But how will the public react to the news that industry knew this could happen all along? With the Dec. 30 explosion in Casselton, and the deadly Bakken oil train explosion in Lac Megantic, Quebec last July, all North Americans ought to question the wisdom of extracting and transporting this highly dangerous oil.
