UPDATE: Latest on West Virginia derailment, explosion

Two recent stories in the media:

1.  WEST VIRGINIA METRO NEWS: No change for CSX, Bakkan oil will continue to roll through area where derailment took place
By Chris Lawrence, February 27, 2015 at 2:47PM

MOUNT CARBON, W.Va. — There will be another CSX train carrying Bakkan oil going through eastern Kanawha and Fayette counties soon now that the track has been repaired following the Feb. 19 derailment of an oil train near Mount Carbon.

“It’s part of the freight that goes over that line,” CSX Spokesman Gary Sease told MetroNews Friday. “Those shipments, along with all the other freight we haul, have resumed.”

The rebuilt line, just a few miles from Montgomery, reopened Thursday afternoon following a week long cleanup.  [CONTINUED]

WASHINGTON — Fiery wrecks of trains hauling crude oil have intensified pressure on the Obama administration to approve tougher standards for railroads and tank cars despite industry complaints that it could cost billions and slow freight deliveries.

On Feb. 5, the Transportation Department sent the White House draft rules that would require oil trains to use stronger tank cars and make other safety improvements.

Nine days later a 100-car train hauling crude oil and petroleum distillates derailed and caught fire in a remote part of Ontario, Canada. Less than 48 hours later, a 109-car oil train derailed and caught fire in West Virginia, leaking oil into a Kanawha River tributary and burning a house to its foundation. As the fire spread across 19 of the cars, a nearby resident said the explosions sounded like an “atomic bomb.” Both fires burned for nearly a week.  [CONTINUED]

A series of horrific train accidents over the past two weeks has opened a floodgate of media news stories, investigative reports, editorials and calls for action.  Local, state and federal first responders and emergency planners, as well as elected and appointed officials have produced an incredible amount of headlines.  As an op-ed in the Richmond Times-Dispatch put it, “Public awareness of these issues is increasing exponentially.”

That is good news for those of us who have been calling for a moratorium on dangerous crude by rail and a cutback and eventual ceasing of production of Bakken crude and Canadian tar-sands dilbit.

Here is a rough sampling of a few of the postings by media nationwide:

MONTANA PUBLIC RADIO: Rail Safety Analysis Sparks Concern Over Oil Trains
By Edward O’Brien, 2/26/15

A new analysis of train safety and recent accidents involving spilled crude oil has caught the attention of many Montanans, especially as more trains carrying oil are moving through the state.  ¶ That’s because a lot crude moves on our rail lines.  ¶ Joe Hanson is well aware of the risk presented by these crude shipments.  ¶ “I went to the door and opened it up and it was just this gray, greenish cloud floating in the street. It was really eerie because of the street lights.”  ¶ That was April 11 of 1996 when 19 Montana Rail Link freight cars derailed near Hanson’s Alberton home. Six of those cars contained hazardous chemicals including chlorine gas.  ¶ The spill killed one person and forced the evacuation of over 1,000 Alberton residents for over two weeks.  [MORE]  [AUDIO]


RICHMOND TIMES-DISPATCH: Op-Ed: Missed opportunities could prove toxic for Virginia
By Greta Bagwell and Emily Russell, February 25, 2015 10:30 pm

The headlines should be familiar to Virginians by now: “River on fire after train derailment”; “Drinking water supplies shut down to thousands after spill”; “Polluters fined for violating environmental laws.” Last week, another CSX train carrying volatile Bakken crude oil from North Dakota derailed in West Virginia. At least 15 rail cars caught fire, sending a neighborhood into evacuation mode….The train cars were state-of-the-art, designed to address safety concerns arising from the transport of a highly flammable fuel. ¶ The intended destination of this fuel? Yorktown, Va. With this train derailment, we have now had two railway accidents on the same railroad that cuts across the commonwealth…. [MORE]


BUFFALO ART VOICE WEEKLY: Buffalo’s Bomb Trains
by Michael I. Niman, 2/26/15

They span over a mile long containing up to 140 tank cars and as much as 4.5 million gallons of some of the nastiest forms of crude oil on earth, pumped from “extreme” extraction operations in North America’s new oil boomtowns. They cross rivers and transverse open plains, wilderness forest and some of the most densely populated urban areas in the country. Occasionally, with alarmingly increasing frequency, they careen off into rivers, catch fire and explode, or both. When spilled in water, their heavy oil exterminates river ecosystems. When they blow up, they release the fires of hell, with one oil train accident in 2013 wiping out most of the town of Lac-Mégantic, Quebec, killing 47 people and gutting its downtown. That’s when folks started referring to these explosive steel snakes as “Bomb Trains.”  [MORE]


 

INSURANCE JOURNAL: Derailed Train in West Virginia Had Safer Tank Cars

Derailed Train in West Virginia Had Safer Tank Cars

By John Raby and Jonathan Mattise | February 26, 2015 

The fiery derailment of a train carrying crude oil in West Virginia earlier this month is one of three in the past year involving tank cars that already meet a higher safety standard than what federal law requires – leading some to suggest even tougher requirements that industry representatives say would be costly.

Hundreds of families were evacuated and nearby water treatment plants were temporarily shut down after cars derailed from a train carrying 3 million gallons of North Dakota crude on Feb. 16, shooting fireballs into the sky, leaking oil into a Kanawha River tributary and burning down a house nearby. It was snowing at the time, but it is not yet clear if weather was a factor.

The train’s tanks were a newer model – the 1232 –designed during safety upgrades voluntarily adopted by the industry four years ago. The same model spilled oil and caught fire in Timmins, Ontario this month, and last year in Lynchburg, Virginia.

A series of ruptures and fires have prompted the administration of President Barack Obama to consider requiring upgrades such as thicker tanks, shields to prevent tankers from crumpling, rollover protections and electronic brakes that could make cars stop simultaneously, rather than slam into each other.

If approved, increased safety requirements now under White House review would phase out tens of thousands of older tank cars being used to carry highly flammable liquids.

“This accident is another reminder of the need to improve the safety of transporting hazardous materials by rail,” said Christopher Hart, acting chairman of the National Transportation Safety Board.

Oil industry officials had been opposed to further upgrading the 1232 cars because of costs. But late last year they changed their position and joined with the railway industry to support some upgrades, although they asked for time to make the improvements.

According to the Association of American Railroads, oil shipments by rail jumped from 9,500 carloads in 2008 to 500,000 in 2014, driven by a boom in the Bakken oil patch of North Dakota and Montana, where pipeline limitations force 70 percent of the crude to move by rail.

The downside: trains hauling Bakken-region oil have been involved in major accidents in Virginia, North Dakota, Oklahoma, Alabama and Canada, where 47 people were killed by an explosive derailment in 2013 in Lac-Megantic, Quebec.

Reports of leaks and other oil releases from tank cars are up as well, from 12 in 2008 to 186 last year, according to Department of Transportation records reviewed by The Associated Press.

Just two days before the West Virginia wreck, 29 cars of a 100-car Canadian National Railway train carrying diluted bitumen crude derailed in a remote area 50 miles south of Timmins, Ontario, spilling oil and catching fire. That train was headed from Alberta to Eastern Canada.

The train that derailed in West Virginia was bound for an oil shipping depot in Yorktown, Virginia, along the same route where three tanker cars plunged into the James River in Lynchburg, Virginia, prompting an evacuation last year.

The train derailed near unincorporated Mount Carbon just after passing through Montgomery, a town of 1,946, on a stretch where the rails wind past businesses and homes crowded between the water and the steep, tree-covered hills. All but two of the train’s 109 cars were tank cars, and 26 of them left the tracks.

Fire crews had little choice but to let the tanks burn themselves out. Each carried up to 30,000 gallons of crude.

One person – the owner of the destroyed home – was treated for smoke inhalation, but no other injuries were reported, according to the train company, CSX. The two-person crew, an engineer and conductor, managed to decouple the train’s engines from the wreck behind it and walk away unharmed.

The NTSB said its investigators will compare this wreck to others including Lynchburg and one near Casselton, N.D., when a Bakken crude train created a huge fireball that forced the evacuation of the farming town.

No cause has been determined, said CSX regional vice president Randy Cheetham. He said the tracks had been inspected just three days before the wreck.

“They’ll look at train handling, look at the track, look at the cars. But until they get in there and do their investigation, it’s unwise to do any type of speculation,” he said.

State officials do have some say over rail safety.

Railroads are required by federal order to tell state emergency officials where trains carrying Bakken crude are traveling. CSX and other railroads called this information proprietary, but more than 20 states rejected the industry’s argument, informing the public as well as first-responders about the crude moving through their communities.

West Virginia is among those keeping it secret. State officials responded to an AP Freedom of Information request by releasing documents redacted to remove nearly every detail.

There are no plans to reconsider after this latest derailment, said Melissa Cross, a program manager for the West Virginia Division of Homeland Security and Emergency Management.

RAILWAY AGE: Why tar sands train became a fireball – bitumen isn’t necessarily safer than Bakken

Repost from Railway Age
[Editor: Significant quote: “This blend of bitumen and petroleum-based diluents, known as “dilbit,” has a low flash point. Thus, the widespread belief that bitumen from Alberta’s northern oil sands is far safer to transport by rail than Bakken crude is, for all intents and purposes, dead wrong.

Why bitumen isn’t necessarily safer than Bakken

By  David Thomas, Contributing Editor, February 23, 2015 
Feb. 14, 2015 CN oil train derailment near Gogama, Ontario

The chain reaction fireballs that attended the Feb. 16, 2015 derailment of a CSX unit oil train in populated West Virginia probably blinded observers to the significance of the concurrent derailment and explosions of a CN oil train in a remote and uninhabited area of northern Ontario. Most reports treated the two events as equals, given that both trains consisted of recently manufactured CPC-1232 tank cars loaded with crude oil.

CN’s Ontario conflagration is the more disturbing of the two mishaps: The railroad reported that its train was not carrying the extra-light Bakken crude that, in a series of high-energy derailments since 2013, has proved to be explosive. To the contrary, the CN train was laden with bitumen, the extra-heavy tarry substance extracted from Alberta’s oil sands. Bitumen, in its natural highly viscous form, is considered to be essentially inflammable by petrochemical experts and is rarely considered in safety evaluations of crude by rail.

So why did the bitumen ignite and explode in Ontario’s -40ºC (-40ºF) weather? The reason, based on research consulted by Railway Age, is that the diluent added to make bitumen flow into and out of tank cars makes the blended lading quite volatile.

This blend of bitumen and petroleum-based diluents, known as “dilbit,” has a low flash point. Thus, the widespread belief that bitumen from Alberta’s northern oil sands is far safer to transport by rail than Bakken crude is, for all intents and purposes, dead wrong. This may be disruptive news for bitumen shippers, carriers, and regulators.

The hope for Bakken crude is that it can be treated to remove benzene and other “light end” substances before loading, rendering it mildly flammable instead of highly explosive. The same is not true for dilbit, because the highly volatile diluents are added to the crude to make it less viscous. A safer procedure is to heat bitumen at origin before loading into a tank car and again at destination, prior to unloading. Some tank cars are equipped with internal steam coils for this purpose and are used in crude oil service, but a requirement for such heating elements is not included in the specifications proposed for a future DOT-117 tank car to replace both the DOT-111 and CPC-1232 cars now in CBR service.

According to “Properties of Dilbit and Conventional Crude Oils,” a February 2014 report by the Alberta Innovates consortium of industry, government, and university researchers, “[T]he flash point of fresh dilbit is initially lower than other oil types and is comparable to a diluent.” It says that dilbit will ignite upon exposure to an ignition source at -35ºC, compared to -9ºC for conventional light oil. The flash point of raw diluent is -35ºC or less. The flash point of undiluted bitumen is +151ºC, well above the +60ºC flammability threshold specified in current hazardous materials classification regulations.

The reason for the low flash point of dilbit is that ignitability is determined by a blend’s most volatile components, in this case, the diluent itself: “[T]he flash point is determined by the lowest-boil-point components (volatiles). Consequently, the flash point of the dilbit is governed by the 20%-30% volume diluent component . . . .”

The study defines flash point as “the temperature to which the fuel must be heated in order to produce an adequate fuel/air concentration to be ignited when exposed to an open flame. The flash point of the crude oil is used as an index of fire hazard in North America.”

Thus, flash point is the critical factor in determining whether a tank car breach will lead to its contents burning or exploding upon exposure to the pyrotechnics of a high-energy derailment.

Canada’s Transportation Safety Board can be expected to analyze the dilbit lading of CN’s Ontario accident, as it did the Bakken crude that exploded at Lac-Mégantic in 2013. TSB reported then that Bakken crude is more volatile than other varieties. Should TSB conclude that dilbit has a volatility similar to Bakken crude, as the Alberta research suggests, the hazmat classification of crude oil could be in question.
