Last week’s oil train derailment in West Virginia launched a national conversation about the safety of shipping oil by rail. It’s a topic we’ve been hearing about over the past couple years, especially here in Minnesota, where Bakken oil crisscrosses the state’s rail lines in large volume.

It’s a complex topic combining federal policy with scientific questions. The Wall Street Journal’s Russell Gold has been following the issue closely and spoke to MPR News’ Tom Weber to explain what you need to know.

Here are 7 things you should know about oil transport by rail:

1. The most misunderstood part of crude oil transport by train: It’s very explosive.

“The kind of oil that’s being taken out of the ground in North Dakota and put into these tanker cars is a much lighter oil,” Gold said. “It is a very gassy oil; it has a lot of ethanes, and butanes and propanes dissolved in it. It really does explode and that’s really what’s causing the problems.”

When a set of tanker cars goes up in flames, it can cause 20-story-tall fireballs.

2. The amount of crude oil carried by train has increased exponentially in less than a decade.

According to the American Association of Railroads, there were 9,500 rail cars carrying crude in 2008. Last year is was 400,000.

We’ve been moving small amounts of crude by rail for years, but it was one or two cars in long train, Gold said. Now we see 100 to 120 tanker cars all filled with crude oil. That’s 70,000 barrels of crude per train, he said.

3. Once the crude oil is extracted in North Dakota, it has to be transported to the country’s major refineries on the coasts.

Refineries are built to utilize the gases removed from the product. If it was stabilized near the extraction site, North Dakota would have to find a way to use or dispose of the ethane and propane gases that make the oil explosive.

4. Railroads have become “virtual pipelines” for oil.

From a Gold WSJ article:

While these virtual pipelines can be created in months, traditional pipelines have become increasingly difficult to install as environmental groups seek to block permits for new energy infrastructure.

“What we are seeing on rail is largely due to opposition to and uncertainty around building pipelines,” said Brigham McCown, who was the chief pipeline regulator under President George W. Bush . Pipelines, he adds, are far safer than trains.

5. Pipeline leaks and spills are environmental problems. Oil train derailments are public safety issues.

When you have a tank car that derails and starts losing it’s very gassy oil, it’s going to burst into fire rather than leak into waterways, Gold said.

6. If you live close to these rail lines, get in touch with local first responders.

Gold recommends checking with emergency responders nearby and ask if they are properly trained to handle a crude oil train derailment. Make sure your fire chief is in contact with the rail companies to know when major shipments come through your area. Push for decreasing train speed limits and increased track inspection.

7. Can we make the tanker cars safer? Gold gave us the latest:

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]

Why bitumen isn’t necessarily safer than Bakken

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.

AP Exclusive: Fuel-hauling trains could derail at 10 a year

By Matthew Brown and Josh Funk, Feb. 22, 2015 12:00 PM ET

BILLINGS, Mont. (AP) – The federal government predicts that trains hauling crude oil or ethanol will derail an average of 10 times a year over the next two decades, causing more than $4 billion in damage and possibly killing hundreds of people if an accident happens in a densely populated part of the U.S.

The projection comes from a previously unreported analysis by the Department of Transportation that reviewed the risks of moving vast quantities of both fuels across the nation and through major cities. The study completed last July took on new relevance this week after a train loaded with crude derailed in West Virginia, sparked a spectacular fire and forced the evacuation of hundreds of families.

Monday’s accident was the latest in a spate of fiery derailments, and senior federal officials said it drives home the need for stronger tank cars, more effective braking systems and other safety improvements.

“This underscores why we need to move as quickly as possible getting these regulations in place,” said Tim Butters, acting administrator for the Transportation Department’s Pipeline and Hazardous Materials Safety Administration.

The volume of flammable liquids transported by rail has risen dramatically over the last decade, driven mostly by the oil shale boom in North Dakota and Montana. This year, rails are expected to move nearly 900,000 car loads of oil and ethanol in tankers. Each can hold 30,000 gallons of fuel.

Based on past accident trends, anticipated shipping volumes and known ethanol and crude rail routes, the analysis predicted about 15 derailments in 2015, declining to about five a year by 2034.

The 207 total derailments over the two-decade period would cause $4.5 billion in damage, according to the analysis, which predicts 10 “higher consequence events” causing more extensive damage and potential fatalities.

If just one of those more severe accidents occurred in a high-population area, it could kill more than 200 people and cause roughly $6 billion in damage.

“Such an event is unlikely, but such damages could occur when a substantial number of people are harmed or a particularly vulnerable environmental area is affected,” the analysis concluded.

The two fuels travel through communities with an average population density of 283 people per square kilometer, according to the federal analysis. That means about 16 million Americans live within a half-kilometer of one of the lines.

Such proximity is equivalent to the zone of destruction left by a July 2013 oil train explosion that killed 47 people and leveled much of downtown Lac-Megantic, Quebec, the analysis said.

Damage at Lac-Megantic has been estimated at $1.2 billion or higher.

A spokesman for the Association of American Railroads said the group was aware of the Department of Transportation analysis but had no comment on its derailment projections.

“Our focus is to continue looking at ways to enhance the safe movement of rail transportation,” AAR spokesman Ed Greenberg said.

Both the railroad group and the Railway Supply Institute, which represents tank car owners and manufacturers, said federal officials had inflated damage estimates and exaggerated risk by assuming an accident even worse than Lac-Megantic, which was already an outlier because it involved a runaway train traveling 65 mph, far faster than others that had accidents.

To get to refineries on the East and West coasts and the Gulf of Mexico, oil shipments travel through more than 400 counties, including major metropolitan areas such as Philadelphia, Seattle, Chicago, Newark and dozens of other cities, according to routing information obtained by The Associated Press through public record requests filed with more than two dozen states.

Since 2006, the U.S. and Canada have seen at least 21 oil-train accidents and 33 ethanol train accidents involving a fire, derailment or significant amount of fuel spilled, according to federal accident records reviewed by the AP.

At least nine of the trains, including the CSX train that derailed in West Virginia, were hauling oil from the Northern Plains’ Bakken region that is known for being highly volatile. Of those, seven resulted in fires.

Both the West Virginia accident and a Jan. 14 oil train derailment and fire in Ontario involved recently built tank cars that were supposed to be an improvement to a decades-old model in wide use that has proven susceptible to spills, fires and explosions.

Safety officials are pushing to make the tanker-car fleet even stronger and confronting opposition from energy companies and other tank car owners.

Industry representatives say it could take a decade to retrofit and modify more than 50,000 tank cars, not the three years anticipated by federal officials, who assumed many cars would be put to new use hauling less-volatile Canadian tar-sands oil.

The rail industry’s overall safety record steadily improved over the past decade, dropping from more than 3,000 accidents annually to fewer than 2,000 in 2013, the most recent year available, according to the Federal Railroad Administration.

But the historical record masks a spike in crude and ethanol accidents over the same time frame. Federal officials also say the sheer volume of ethanol and crude that is being transported – often in trains more than a mile long – sets the two fuels apart.

Most of the proposed rules that regulators are expected to release this spring are designed to prevent a spill, rupture or other failure during a derailment. But they will not affect the likelihood of a crash, said Allan Zarembski, who leads the railroad engineering and safety program at the University of Delaware.

Derailments can happen in many ways. A rail can break underneath a train. An axle can fail. A vehicle can block a crossing. Having a better tank car will not change that, but it should reduce the odds of a tank car leaking or rupturing, he said.

Railroads last year voluntarily agreed to reduce oil train speeds to 40 mph in urban areas. Regulators said they are considering lowering the speed limit to 30 mph for trains not equipped with advanced braking systems. Oil and rail industries say it could cost $21 billion to develop and install the brakes, with minimal benefits.
