CULBERTSON, Mont. — Five train derailments have occurred in less than two years in the northeastern Montana County where crews continue cleaning up after last week’s oil train derailment.

In addition to the two train derailments that occurred last week within a 20-mile stretch of Roosevelt County, two railcars also derailed at Culbertson in February, according to the Federal Railroad Administration database, which is updated through April.

The cause of that incident, which did not cause injuries or release of hazardous material, was attributed to human error, according to information submitted to the FRA.

The area also had two train derailments in 2014, including the derailment of two Amtrak cars in April of that year in the neighboring community of Bainville.

Two people were hurt in the derailment, which caused more than $100,000 in damage to Amtrak equipment and nearly $500,000 in damage to the track, the FRA database shows.

The cause that derailment is listed as “track roadbed settled or soft,” according to information submitted to the FRA.

The other 2014 incident, which involved one railcar that derailed in December at Culbertson, was attributed to a broken wheel, the FRA database shows.

The entire state of Montana had 19 train derailments in 2014, the FRA information shows.

Last Tuesday, nine railcars derailed near Blair, Mont., damaging about 1 mile of track. The cause remains under investigation.

BNSF Railway inspects the track in that area at least four times per week, spokesman Matt Jones said.

The FRA and the Pipeline and Hazardous Materials Safety Administration continued collecting evidence Monday to investigate the cause of Thursday’s derailment involving 22 oil tankers. Four of the derailed tank cars leaked oil, the FRA said, and spilled an estimated 35,000 gallons of oil.

The train was not speeding at the time it derailed, an FRA spokesman said. It was traveling 44 miles per hour in a 45-mph zone, the spokesman said.

BNSF environmental specialists continue to clean up at the site. Oil will be removed from the remaining tank cars in the next several days, and the cars will be removed after that, Jones said.

Crews are excavating contaminated soil, said Daniel Kenney, enforcement specialist with the Montana Department of Environmental Quality, which is monitoring the cleanup. The spill was not reported to have contaminated any water sources and has not threatened human health, Kenney said.

The North Dakota Department of Mineral Resources confirmed Monday that Statoil, the company that owns the oil that was on the train, is in compliance with the state’s oil conditioning order.

The order, which took effect in April, aims to reduce the volatility of Bakken crude oil.

Statoil was meeting the order by operating its equipment at specific temperatures and pressures, said Department of Mineral Resources spokeswoman Alison Ritter. Companies also can comply by submitting vapor pressure tests to the state.

The train with was loaded by Savage Services in Trenton, N.D., and headed to Anacortes, Wash., the FRA said.

Jeff Hymas, a spokesman for Savage Services, said Monday the railcar inspection protocols at the Trenton terminal are consistent with FRA and BNSF requirements.

Battle Over New Oil Train Standards Pits Safety Against Cost

By David Schaper, June 19, 2015 3:30 AM ET

A train carrying crude oil derailed in Mount Carbon, W.Va., in February, causing a large fire that forced hundreds of people to evacuate their homes.

The federal government’s new rules aimed at preventing explosive oil train derailments are sparking a backlash from all sides.

The railroads, oil producers and shippers say some of the new safety requirements are unproven and too costly, yet some safety advocates and environmental groups say the regulations aren’t strict enough and still leave too many people at risk.

Since February, five trains carrying North Dakota Bakken crude oil have derailed and exploded into flames in the U.S. and Canada. No one was hurt in the incidents in Mount Carbon, W.Va., and Northern Ontario in February; in Galena, Ill., and Northern Ontario in March, and in Heimdal, N.D., in May.

But each of those fiery train wrecks occurred in lightly populated areas. Scores of oil trains also travel through dense cities, particularly Chicago, the nation’s railroad hub.

According to state records and published reports, about 40 or more trains carrying Bakken crude roll through the city each week on just the BNSF Railway’s tracks alone. Those trains pass right by apartment buildings, homes, businesses and even schools.

“Well just imagine the carnage,” said Christina Martinez. She was standing alongside the BNSF tracks in Chicago’s Pilsen neighborhood as a long train of black tank cars slowly rolled by, right across the street from St. Procopius, the Catholic elementary school her six-year-old attends.

“Just the other day they were playing soccer at my son’s school on Saturday and I saw the train go by and it had the ‘1267’, the red marking,” Martinez said, referring to the red, diamond-shaped placards on railroad tank cars that indicates their contents. The number 1267 signifies crude oil. “And I was like, ‘Oh my God.’ Can you imagine if it would derail and explode right here while these kids are playing soccer and all the people around there?”

New federal rules require stronger tank cars, with thicker shells and higher front and back safety shields for shipping crude oil and other flammable liquids. Older, weaker models that more easily rupture will have to be retrofitted or replaced within three to five years. But Martinez and others wanted rules limiting the volatility of what’s going into those tank cars, too.

Oil from North Dakota has a highly combustible mix of natural gases including butane, methane and propane. The state requires the conditioning of the gas and oil at the wellhead so the vapor pressure is below 13.7 pounds per square inch before it’s shipped. But even at that level, oil from derailed tank cars has exploded into flames.

And many safety advocates had hoped federal regulators would require conditioning to lower the vapor pressure even more.

“We don’t want these bomb trains going through our neighborhood,” said Lora Chamberlain of the group Chicagoland Oil by Rail. “Degasify the stuff. And so we’re really, really upset at the feds, the Department of Transportation, for not addressing this in these new rules.”

Others criticize the rules for giving shippers three to five years to either strengthen or replace the weakest tank cars.

“The rules won’t take effect for many years,” said Paul Berland, who lives near busy railroad tracks in suburban Elgin. “They’re still playing Russian roulette with our communities.”

A coalition of environmental groups — including Earthjustice, ForestEthics and the Sierra Club — sued, alleging that loopholes could allow some dangerous tank cars to remain on the tracks for up to a decade.

“I don’t think our federal regulators did the job that they needed to do here; I think they wimped out, as it were,” said Tom Weisner, mayor of Aurora, Ill., a city of 200,000 about 40 miles west of Chicago that has seen a dramatic increase in oil trains rumbling through it.

Weisner is upset the new rules provide exemptions to trains with fewer than 20 contiguous tank cars of a flammable liquid, such as oil, and for trains with fewer than 35 such tank cars in total.

“They’ve left a hole in the regulations that you could drive a freight train through,” Weisner said.

At the same time, an oil industry group is challenging the new regulations in court, too, arguing that manufacturers won’t be able to build and retrofit tank cars fast enough to meet the requirements.

The railroad industry is also taking action against the new crude-by-rail rules, filing an appeal of the new rules with the Department of Transportation.

In a statement, Association of American Railroads spokesman Ed Greenberg said: “It is the AAR’s position the rule, while a good start, does not sufficiently advance safety and fails to fully address ongoing concerns of the freight rail industry and the general public. The AAR is urging the DOT to close the gap in the rule that allows shippers to continue using tank cars not meeting new design specifications, to remove the ECP brake requirement, and to enhance thermal protection by requiring a thermal blanket as part of new tank car safety design standards.”

AAR’s President Ed Hamberger discussed the problems the railroads have with the new rules in an interview with NPR prior to filing the appeal. “The one that we have real problems with is requiring something called ECP brakes — electronically controlled pneumatic brakes,” he said, adding the new braking system that the federal government is mandating is unproven.

“[DOT does] not claim that ECP brakes would prevent one accident,” Hamberger said. “Their entire safety case is based on the fact that ECP brakes are applied a little bit more quickly than the current system.”

Acting Federal Railroad Administrator Sarah Feinberg disagreed. “It’s not unproven at all,” she said, noting that the railroads say ECP brakes could cost nearly $10,000 per tank car.

“I do understand that the railroad industry views it as costly,” Feinberg adds. “I don’t think it’s particularly costly, especially when you compare it to the cost of a really significant incident with a train carrying this product.”

“We’re talking about unit trains, 70 or more cars, that are transporting an incredibly volatile and flammable substance through towns like Chicago, Philadelphia,” Feinberg continues. “I want those trains to have a really good braking system. I don’t want to get into an argument with the rail industry that it’s too expensive. I want people along rail lines to be protected.”

Feinberg said her agency is still studying whether to regulate the volatility of crude, but some in Congress don’t think this safety matter can wait.

“The new DOT rule is just like saying let the oil trains roll,” U.S. Sen. Maria Cantwell, D-Wash., said in a statement. “It does nothing to address explosive volatility, very little to address the threat of rail car punctures, and is too slow on the removal of the most dangerous cars.”

Cantwell is sponsoring legislation to force oil producers to reduce the crude’s volatility to make it less explosive, before shipping it on the nation’s rails.

Latest ‘bomb train’ incident predictable

Latest ‘bomb train’ incident predictable

By Kathleen Sloan, May 11, 2015

BNSF Railway carried the Hess Corp.-owned rail car, which carried highly volatile Bakken crude oil from North Dakota and appears to have followed the law.

President Barack Obama weighed and rejected using executive authority to curb the transport of this explosive crude oil, rich in butane and propane, because he decided North Dakota state law should be the controlling authority. But the law North Dakota passed in December and went into effect just last month, only requires less than 13.7 pounds-per-square-inch vapor pressure inside the tanker, despite explosions at lower pressures.

That’s almost 40 percent more than the average vapor pressure among the 63 tanker cars that exploded July 6, 2013, at Lac-Megantic, Quebec. That disaster killed 47 people, some of whom could not be found because they were vaporized, and is driving recent federal and state rail car regulations.

According to an Albany, N.Y., Times Union investigation, the average vapor pressure among 72 tanker cars in the Lac-Megantic train was 10 psi.

Hess Corp. tested the crude just before loading at 10.8 psi, according to Associated Press reporters Matthew Brown and Blake Nicholson, in their follow-up story about the derailment at Heimdal, N.D.

While federal regulations only require flash point and boiling point to be measured, North Dakota now requires vapor pressure be measured. But measuring and labeling the danger does not make transporting it safe.

The U.S. Department of Transportation’s two divisions, the Federal Railroad Administration and the Pipeline and Hazardous Materials Safety Administration, are the regulating authorities overseeing railway transport of crude oil. Generally, the FRA is responsible for train car and rail safety, while the PHMSA inspects the proper testing of the oil. That determines the oil’s proper classification and its proper “packaging” in pressurized cars and their labeling.

Other PHMSA duties include checking shipping documents to see if the shipper has self-certified the procedures properly as well as employee safety and handling training.

The U.S. DOT initiated “Operation Safe Delivery” in August 2013, in reaction to the Lac-Megantic incident, although the Bakken oil boom dates to 2008.

A federal rule-making process also began in August 2013. Those rules went into effect last week.

PHMSA, as part of Operation Safe Delivery, took several samples of Bakken crude oil from rail-loading facilities, storage tanks and pipelines used to load rail cars. Several also were collected from cargo tanks.

The first set of samples were taken August through November 2013 and the second set February through May 2014.

The first set showed psi vapor pressure among a dozen samples ranging from 7.7 psi to 11.75 psi.

A second set of 88 samples showed vapor pressure ranging from 10.1 psi to 15.1, with the average at about 12 psi.

Only six of the 88 samples were at or exceeded North Dakota’s 13.7 psi. This means shippers are not required to treat most of the crude generated from the Bakken oil formation before loading it onto cars.

The “Operation Safe Delivery Update,” available on the PHMSA website, also gives test results for propane, sulphur, hydrogen sulfide, methane and butane content.

The conclusions in the Operations Safe Delivery Update, which was not dated, are:

“Bakken crude’s high volatility level — a relative measure of a specific material’s tendency to vaporize — is indicated by tests concluding that it is a ‘light’ crude oil with a high gas content, a low flash point, a low boiling point and high vapor pressure …

“Given Bakken crude oil’s volatility, there is an increased risk of a significant incident involving this material due to the significant volume that is transported, the routes and the extremely long distances it is moving by rail… These trains often travel over a thousand miles from the Bakken region to refinery locations along the coasts…”

And although the report states, “PHMSA and FRA plan to continue … to work with the regulated community to ensure the safe transportation of crude oil across the nation,” the new rules that went into effect last week did nothing about regulating vapor pressure.

Instead, the rules phase out weaker and older pressurized tanker cars, the DOT-111, by 2020, and phase in CPC-1232 cars.

So far, at least four derailments of CPC-1232 cars carrying Bakken oil have exploded:

    • March 5 in Galena, Ill.;
    • Feb. 1 in Mount Carbon, W.Va.;
    • Feb. 15 near Timmons, Ontario; and
    • Last year in Lynchburg, Va.

Experts in various news articles and public comment submitted during the federal rule-making stated the way to make transport safe is to refine the crude before shipping. That would involve building refineries near the extraction point, which experts pointed out would be expensive.

In a Sept. 26, 2014, story, Railway Age contributing editor David Thomas applauded North Dakota for “using state jurisdiction over natural resources to fill the vacuum created by the federal government’s abdication of its constitutional responsibility for rail safety and hazardous materials.”

But Thomas admitted the state law on crude treatment would reduce the danger only slightly.

“Simply put, North Dakotan crude will have to be lightly pressure-cooked to boil off a fraction of the volatile ‘light ends’ before shipment,” Thomas said. “This conditioning lowers the ignition temperature of crude oil — but not by much. It leaves in solution most of the culprit gases, including butane and propane. Even the industry itself says conditioning would not make Bakken crude meaningfully safer for transportation, though it would make the state’s crude more consistent from one well to another.”

“The only solution for safety is stabilization, which evaporates and re-liquifies nearly all of the petroleum gases for separate delivery to refiners,” Thomas said.

He points out owners and shippers in the Eagle Fork formation in Texas, voluntarily stabilize their crude before shipping. It’s more volatile than Bakken crude.

“So far, stabilized Eagle Fork crude has been transported by tank car as far away as Quebec City, without the fireballs that have plagued the shipment of unstabilized Bakken crude,” Thomas said. “The Texan gases are liquefied and piped underground to the state’s Gulf Coast petrochemical complex for processing and sale.”

Keeping the volatile gases in solution during shipping, while dangerous, is profitable.

Thomas said North Dakota has no nearby petrochemical plants, which “explains the oil industry’s collective decision not to extract the otherwise commercially valuable gases from North Dakota crude oil. Instead, most of the explosive gases remain dissolved in the unstabilized Bakken oil for extraction after delivery to distant refineries.”

The PHMSA, however, requires butane and propane be removed from the crude before it is injected into pipelines, Thomas said.

Comments to the federal rule-making pointed out Bakken oil is made more dangerous still by corrosive chemicals used in the fracking process. The crude is further treated with chemicals to make the molasses-like consistency easier to pump.

Severe corrosion to the inner surface of the tanker cars, manway covers, valves and fittings have been recorded in various incidents, commentators said.

The lack of federal regulations is not the only problem. Enforcement is minimal because there are only 56 inspectors, according to PHMSA spokesman Gordon Delcambre.

Ten of those have been assigned to the North Dakota Bakken oil formation region, he said.

In the PHMSA 2013 annual enforcement report, 151 cases were prosecuted and 312 civil penalty tickets were issued, resulting in $1.87 million in fines. The largest fine was $120,200.

The report did not mention what the hazardous material was in 173 of the 463 enforcement actions.

Only one enforcement action appeared to result from an inspection of “fuel oil” transport, which resulted in a $975 fine for incorrect “packaging” and failure to prove, through documents, employees had been given the required safety and hazardous material handling training.

According to BNSF Railway’s report to the state Homeland Security and Emergency Management, required by a U.S. DOT emergency order since May 2014, a range of zero-to-six trains carrying at least 1 million gallons (30,000 gallons per car or about 35 cars or more) pass through Burlington each week.

Oil in North Dakota derailment was “Conditioned” but not “Stabilized”

Repost rom ABC News
[Editor:  Note that the oil was CONDITIONED according to North Dakota regulations, but it was not STABILIZED which is a stricter standard currently used elsewhere.  (See The difference between oil “conditioning” and oil “stabilization”.)  The vapor pressure of oil on this train was measured at 10.8 psi. Compare this with DeSmogBlog: “…regular crude oil has a Reid Vapor Pressure (RVP) of 5-7 psi and Bakken crude has an RVP between 8-16 psi. To put that in perspective, gasoline typically has a RVP of 9 psi.”  Note also: “The North Dakota train was traveling 24 miles an hour…much slower than the 50 mph limit imposed by federal regulators.”  – RS]

Oil in North Dakota Derailment Was Treated to Cut Volatility

By Matthew Brown and Blake Nicholson, Associated Press, May 7, 2015, 7:09 PM ET

BISMARCK, N.D. — A shipment of oil involved in an explosive train derailment in North Dakota had been treated to reduce its volatility — a move that state officials suggested could have reduced the severity of the accident but won’t prevent others from occurring.

Hess Corporation spokesman John Roper said the oil complied with a state order requiring propane, butane and other volatile gases to be stripped out of crude before it’s transported. That conditioning process lowers the vapor pressure of the oil, reducing the chances of an explosive ignition during a crash.

Despite the treatment of the crude in Wednesday’s accident, six cars carrying a combined 180,000 gallons of oil caught fire in the derailment 2 miles from the town of small Heimdal in central North Dakota. The town was evacuated but no one was hurt.

Investigators on Thursday recovered wheel fragments from the scene. Those will be sent to a government laboratory for analysis, said National Transportation Safety Board spokesman Keith Holloway. A defective tank car wheel is suspected to have played a role in another oil train accident, in Galena, Illinois, on March 10.

The North Dakota train was traveling 24 miles an hour, Holloway said, much slower than the 50 mph limit imposed by federal regulators.

The state volatility standard went into effect last month. It came in response to a string of fiery oil train accidents, including a 2013 derailment in Lac-Megantic, Quebec that killed 47 people and a derailment and fire near Casselton, North Dakota last year.

Members of Congress have called for a stricter, national volatility standard for crude moved by rail.

Roper said the Hess shipment was “fully in compliant with North Dakota’s crude conditioning order.” It was tested immediately prior to loading onto a BNSF Railway train in Tioga and had a vapor pressure of 10.8 pounds per square inch — compared to the 13.7 pounds per square inch maximum under the state standard.

Reducing the explosiveness of crude moved by rail was not supposed to be a cure-all. Federal regulators last week announced a new rule that calls for stronger tank cars better able to withstand a derailment and more advanced braking systems to help keep fuel-carrying cars on the tracks.

“Our oil conditioning order in no way will prevent an accident,” said Alison Ritter with the North Dakota Industrial Commission, which set the vapor pressure standard. “Oil is still going to burn. That’s why the oil was produced. But it’s not as explosive.”

The first witness on the scene Wednesday, 68-year-old Heimdal resident Curt Benson, said he heard and felt an explosion in his house and then witnessed three or four more explosions when he got to the scene. He said it was nowhere near the magnitude of the Casselton explosions, which he saw on television footage.

“I would say that ours was somewhat minor compared to theirs,” Benson said.

Casselton Fire Chief Tim McLean said the disaster outside of that city appeared much worse than the Heimdal incident, but there were other factors to consider than just the volatility of the oil. The Casselton derailment involved more than twice the amount of crude and different kinds of tanker cars, he said. Another freight train, carrying soybeans, also was involved in Casselton and provided more fuel for the fire.

Democrats in Congress contend more needs to be done to reduce the danger of oil shipments by rail that pass through more than 400 counties including major metropolitan areas such as Seattle, Chicago and Philadelphia. Most of that oil comes from the Bakken region of North Dakota, Montana and Canada.

“Why do we let trains with this volatility pass through every day? Why are we letting these guys get away with that?” U.S. Sen. Maria Cantwell, a Washington state Democrat, said in an interview last week after federal regulators unveiled the braking and tank car rule.

BNSF vice president Mike Trevino did not immediately know how much of the oil in Heimdal burned, how much spilled and how much was left in the cars after the fire was extinguished.

The railway was working to remove the derailed cars and repair the track Thursday. It planned to re-open the line Friday afternoon, Trevino said.

The line runs next to an intermittent waterway known as the Big Slough, which drains into the James River about 15 miles downstream. Oil got into the slough, but it was contained and was being recovered, state Emergency Services spokeswoman Cecily Fong said early Thursday.

The tank cars that burst into flames were a model slated to be phased out or retrofitted by 2020 under a federal rule announced last week. It’s the fifth fiery accident since February involving that type of tank car, and industry critics called for them to be taken off the tracks immediately to prevent further fires.

For residents of Heimdal and surrounding Wells County, which oil trains cross daily, the disaster was the realization of something they always feared might happen, County Commission Chairman Mark Schmitz said.

“It’s definitely been in the back of everybody’s minds,” he said.
