Another Bomb Train Accident Highlights Regulatory Failures

A train carrying over 100 cars of volatile Bakken oil derailed in Washington state, causing the evacuation of the town of Custer. At least two of the train cars ruptured and the oil ignited and burned — reminding us once again why these dangerous trains are known as bomb trains. 

Matt Krogh of Stand.earth has been leading efforts to keep these dangerous trains off the tracks for years, so he was well aware of the potential deadly consequences of oil train accidents in populated areas. Krogh could see the smoke from this latest accident from his home in Bellingham, Washington.

I think we got lucky today,” Krogh told the Associated Press, echoing the words of others after previous close calls with oil trains — several of which were highlighted in the DeSmog piece Luck Rides the Rails. 

It’s easy to feel lucky after a near miss with an oil train derailment and fire near a populated area because in 2013 an oil train full of Bakken oil derailed and caused catastrophic fires and explosions in the Canadian town of Lac-Mégantic, Quebec, — killing 47 people and destroying much of the downtown area. Downtown Lac-Mégantic has yet to be rebuilt more than seven years later.

Regulators Argue Safety Is Not A Pretext for Regulation

The state of Washington is well aware of the dangers the oil trains pose to the public and the environment and have attempted to address this issue with state regulations. Washington has five oil refineries that all are highly dependent on Bakken crude by rail. Crude-by-rail movements in the U.S. and Canada fluctuate significantly based on market conditions, but the Washington refineries are one destination for Bakken oil that maintain consistent demand for the oil, and rail is the only option to get it to Washington — so the risks to Washington residents who live near the train tracks are ever present.

In 2016 a Bakken oil train derailed in Mosier, Oregon along the Columbia River highlighting the risk the trains pose in the Pacific Northwest. Many trains bring the Bakken oil through Oregon and the Columbia River gorge to Washington.

In my 2019 book Bomb Trains: How Industry Greed and Regulatory Failure Put the Public at Risk I explain why the trains carrying highly volatile Bakken oil are dangerous and the simple steps the oil and rail industries could take to remove these dangers. All are steps the industries have successfully lobbied against despite the risks to the public and the 47 fatalities in Lac-Mégantic.

Washington regulators and politicians tried to take the most important safety step by passing a law that limited the volatility of the crude oil being moved by rail through Washington, a move that would greatly reduce the risk of fires and explosions during derailments. A rule proposed at the end of the Obama administration to limit the volatility was officially withdrawn by the Trump administration in May of 2020.


If the federal government won’t act to protect public safety and adopt a safer nationwide standard, we will adopt our own,” state Sen. Andy Billig (D-Spokane) said in March 2019 of the bill he sponsored. “There is just too much to lose — for people and our environment.”

As DeSmog reported in May, the Pipeline and Hazardous Materials Safety Administration (PHMSA) did act, but that action was to overrule Washington’s proposed regulation with the argument that safety regulations could not get in the way of markets — arguing that a state can not use “safety as a pretext for inhibiting market growth.”

New Administration May Offer Chance at Safety Regulations

The act by the Trump administration’s regulators of withdrawing the proposed federal rule to limit oil volatility for transportation of crude oil by rail by was consistent with the official stated policy of deregulation with regards to rail safety.

This policy led to the removal of the most important safety regulation for oil-by-rail transportation that was enacted during the Obama era, which would have required oil trains to have modernized braking systems. The Trump administration removed that regulation in December of 2017.

The incoming Biden administration will have the opportunity to finally address the known dangers of moving hazardous oil, ethanol and liquefied natural gas (LNG) by rail. Reinstating the braking requirement and regulating oil volatility would be important first steps. Two other areas that would improve safety would be limiting train lengths and requiring tank cars that weren’t easily punctured in derailments.

DeSmog has reported on how longer trains derail more often and yet there are no regulations for train length for trains moving hazardous materials. Most of the major derailments involving oil trains have involved trains with more than 100 cars, like the train in Custer.

The 2015 regulations for new tank cars for oil trains required the use of new DOT-117 model tank cars. As they did in this latest derailment, these tank cars have failed in all of the major derailments involving the cars hauling oil and ethanol.

Four years of the Trump administration overseeing the rail industry has put the public at even greater risk. The administration’s reckless approval of LNG-by-rail without proper safety testing or new regulations greatly increases the future danger to the public if the LNG industry starts using rail as a major mode of transportation.

Pete Buttigieg has been nominated to be the next Secretary of Transportation where he will have oversight of rail safety. At the very least Buttigeig could begin to protect the public by simply reinstating the oil-by-rail safety regulations that have been repealed, and then moving forward with the proposed regulations to limit the volatility of any crude oil moved by rail.

Until the oil and rail industries are properly regulated, the public will continue to be at great risk from bomb trains and will have to trust in luck to keep them safe.

Trump admin’s stunning explanation for easing up on oil trains: Safety no excuse for “inhibiting market growth”

Safety Can’t Be a ‘Pretext’ for Regulating Unsafe Oil Trains, Says Trump Admin

The federal agency overseeing the safe transport of hazardous materials released a stunning explanation of its May 11 decision striking down a Washington state effort to regulate trains carrying volatile oil within its borders. A state cannot use “safety as a pretext for inhibiting market growth,” wrote Paul J. Roberti, the chief counsel for the Pipeline and Hazardous Materials Safety Administration (PHMSA).

The statement appeared in the Trump administration’s justification for overruling Washington’s oil train regulation, which was challenged by crude-producing North Dakota and oil industry lobbying groups. The Washington rule seeks to limit oil vapor pressure unloaded from trains to less than 9 pounds per square inch (psi) in an attempt to reduce the likelihood that train derailments lead to the now-familiar fireballs and explosions accompanying trains transporting volatile oil.

Roberti wrote: “Proponents of the law insist Washington State has a legitimate public interest to protect its citizens from oil train fires and explosions, but in the context of the transportation of crude oil by rail, a State cannot use safety as a pretext for inhibiting market growth or instituting a de facto ban on crude oil by rail within its borders.”

With this statement, PHMSA is codifying what has been clear for some time at the regulatory agencies responsible for overseeing the transportation of hazardous materials by rail: that is, profits take priority over safety.

Rail Industry ‘Pre-emption’ and Safety Under Trump

A year ago, the U.S. Department of Transportation (DOT), PHMSA‘s parent agency, invoked the same legal argument, known as “pre-emption,” to overrule state efforts to require at minimum two-person crews for operating freight trains. As part of the explanation for that decision, the DOT‘s Federal Railroad Administration announced that it was adopting a policy of deregulation.

DOT’s approach to achieving safety improvements begins with a focus on removing unnecessary barriers and issuing voluntary guidance, rather than regulations that could stifle innovation,” wrote the agency.

A regulatory agency announcing a broad deregulatory agenda was shocking. However, this latest move openly declares that, while Washington state may have an interest in protecting its citizens from “oil train fires and explosions,” that concern should not get in the way of the oil industry’s ability to ship more of its product by rail through the state, apparently even if that increases the risk of oil train fires and explosions to Washington residents. This logic reaches a new level of prioritizing profits over people as regulatory practice.


Historically, or at least, theoretically, government has based regulations on cost-benefit analyses, weighing the costs of complying for the regulated entities against the benefits, such as lives saved or accidents prevented, as a result of the new rules. Here, the DOT‘s new regulatory approach appears to weigh primarily the benefits for the rail and oil industries while downplaying the potential cost in human lives.

However, these industries did argue about costs to get to this point. As DeSmog has repeatedly documented, lowering the vapor pressure of oil below 9 psi is possible through a process called stabilization, which makes oil less volatile and less likely to ignite. Conditioning the oil in this way before loading on trains would require the oil industry to invest in stabilization equipment, which the industry has argued is not economically feasible.

In 2014, Myron Goforth, the president of Dew Point Control LLC, a manufacturer of stabilization equipment, put the situation in simple terms. “It’s very easy to stabilize the crude — it just takes money,” Goforth told Reuters. “The producer doesn’t want to pay for it if he can ship it without doing it.”

DOT‘s May 11 decision notes that “compliance with the [Washington] law can only be accomplished by (1) pretreating the crude oil prior to loading the tank car.” Exactly: Making the oil safe to ship on long, heavy trains through small towns and large cities requires stabilizing, or conditioning, before loading it into tank cars (just as the industry does before loading oil in pipelines or on ocean-going tankers, at least in Texas). DOT makes no argument about how companies could comply with the Washington law, outside of trying to avoid passing through the state entirely or using a different transportation mode other than trains.

A particularly telling clue behind the DOT‘s conclusion that the Washington law should be pre-empted is found in the commenters whose opinions the agency is highlighting: “In light of the infrastructure, equipment, and other logistical issues, the commenters have concluded that pretreating is economically infeasible or unrealistic.”

In this case, the “commenters” the DOT is referencing are members of the oil industry and its lobbyists, including the refinery company Hess Corporation, Marathon Petroleum, the American Petroleum Institute (API), American Fuel and Petrochemical Manufacturers, and the North Dakota Petroleum Council.

At an oil-by-rail conference in 2016, an API official described the industry’s attitude about the prospect of requiring oil stabilization for rail transport: “We in the oil and gas industry see this as a very dangerous conversation.”


In December 2017, Trump’s Federal Railroad Administration repealed an Obama-era rule requiring modern braking systems on oil trains despite overwhelming evidence that these systems improve rail safety. Sarah Feinberg, former head of the Federal Railroad Administration, offered important context about rail industry opposition to that rule.

The science is there, the data is there,” Feinberg said of the efforts to require updated rail braking systems on oil trains. “Their argument is, despite that data, [they] don’t want to spend the money on it.”

That seems to be the rule for overseeing rail safety under the Trump administration. If a rule costs industry money to improve safety and protect the public from oil train fires and explosions, the industry will push back against its regulators, who appear to be pushovers, especially but not exclusively under Trump.

The alternative of prohibiting oil transportation by rail, because it is apparently too dangerous and too costly to do safely, is never even considered.

Ignoring the Science

The latest decision on the Washington state case continues a trend under Trump to overlook robust science when regulating oil by rail. However, you might not know it from the comments of this decision’s supporters.

PHMSA used a single, flawed study from Sandia National Laboratories to support its conclusion that limiting the vapor pressure of oil moved by rail is unnecessary — while the agency ignored all the other established research on vapor pressure, volatility, and ignitability of crude oil.

The North Dakota Congressional delegation opened its statement praising the May 11 decision with lip service to science: “We thank the administration for doing the right thing by putting sound, scientific evidence above partisan politics.”

In the same vein, Ron Ness, president of the North Dakota Petroleum Council, told the Associated Press, “There is nothing unusual about the volatility of Bakken crude oil,” a claim the North Dakota attorney general has also made to argue against the Washington vapor pressure law.

And yet these statements don’t stand up to scrutiny. In my book Bomb Trains: How Industry Greed and Regulatory Failure Put the Public at Risk, I present the evidence that Bakken crude oil’s volatility is higher than other regions and that this factor makes a difference. This crude oil is much more volatile than traditional crude oil from Louisiana or Texas, and that volatility, along with other factors, makes it more likely to ignite in oil train derailments.

WATCH: Justin Mikulka, Sept 2015: The Science of Bomb Trains

As I noted at the time of its publishing, the Sandia Labs study is deeply flawed and does not study the actual issue of oil igniting during train derailments.

As for whether Bakken oil’s volatility is “unusual,” a Wall Street Journal analysis found in 2014 that “Crude oil from North Dakota’s Bakken Shale formation contains several times the combustible gases as oil from elsewhere.” These combustible gases are what give the Bakken oil much higher vapor pressure levels than most other crude oils from the U.S.

The combustible gases in the oil are natural gas liquids like butane and propane, which is why the oil is so volatile.

At the same time that the oil industry tries to say Bakken oil isn’t more volatile than other oils, it argues that Bakken oil’s value lies in these extra natural gas liquids. Stabilizing the oil by removing these gases from the oil not only would cost the industry money but the resulting oil would be worth less to the industry.

The DOT notes as much in its recent decision: “These higher vapor pressure hazardous materials, such as butane, ethane, and other natural gases, are deemed essential and valuable components of Bakken crude.”

The oil industry has no argument to make on a scientific basis here, only an economic one. Reducing the vapor pressure of oil by removing gases like butane and ethane makes it less volatile and less likely to ignite. That is established by research. But the industry has repeatedly argued that removing these flammable gases from the oil would make it less valuable, which is one of its justifications for not stabilizing the oil.

A Second Bakken Bomb Train Boom Could Be on the Way

The only things that have kept the estimated 25 million North Americans living along railroad blast zones safer from dangerous oil trains is the success of activists who have blocked new oil-by-rail projects and oil industry economics. Because transporting oil by rail is more expensive than by pipeline or ocean-going tankers, the industry moves much less oil on trains when oil prices are low.

With current oil prices at record lows in the U.S. and Canada, it doesn’t make economic sense to move oil by rail, which is good news for the millions of people living along the rails.

However, a current legal battle over the Dakota Access pipeline could make moving Bakken oil by rail a major mode of transportation, perhaps regardless of oil price.

A judge recently set a hearing to review the permitting process for the controversial pipeline, currently moving 500,000 barrels of crude per day. Depending on the outcome, that hearing could result in the judge vacating the pipeline’s permits, shutting it down and diverting all of that Bakken oil back onto the rails in a big way, at levels that would surpass the records of 2014. The Obama administration passed oil train safety regulations in 2015 in response to the fiery accidents and oil spills that coincided with the boom in oil train traffic.

The Trump administration has steadily worked to roll back the modest progress of those safety rules, with the last one, on vapor pressure for oil by rail, withdrawn from the rulemaking process the very same day the DOT pre-empted Washington’s vapor pressure rule.

Now, an essentially unregulated oil-by-rail industry poses a real risk to public safety and the environment. With the Trump administration shooting down Washinton’s rule and repealing previous safety regulations, the risks of moving volatile oil by rail are essentially the same as in 2013. That was the same year a train hauling Bakken oil exploded in downtown Lac-Mégantic, Quebec, and killed 47 people.

Today, Bakken oil is just as volatile — and dangerous. The trains pulling upwards of a hundred cars of oil have the same outdated braking systems. Regulators have no requirements overseeing train track integrity or wear (the two latest oil train derailments and fires in Canada were likely because of track failures). There are no regulations on train length. And while rail companies have phased in a newer class of tank cars, those cars have ruptured in every major derailment involving oil and ethanol trains.

The accident in Lac-Mégantic happened almost seven years ago. An early Wall Street Journal article after the accident quoted an oil industry executive who said, “Crude oil doesn’t explode like that.”

Which is true in most cases. But Bakken crude does explode like that because it is full of gases like butane, is highly volatile, and has much higher vapor pressure than most other crude oils.

While that doesn’t have to be true, the Trump administration is taking steps to make sure it is.

The Canadian Government is Blowing Up Bomb Trains for Practice

The Canadian Government is Blowing Up Bomb Trains for Practice

By Hilary Beaumont, March 18, 2016 | 9:51 am

Two and a half years after a train carrying crude oil ran off the tracks in Lac-Mégantic, Quebec and exploded, killing 47 people, the Canadian government set a tanker on fire and pretended to run a train off its tracks as practice in case it happens again.

On July 6, 2013, an unmanned train carrying ultra-flammable western crude plummeted into the downtown of 6,000-resident Lac-Mégantic, where it erupted in flames and flattened everything in its path. The Lac-Mégantic tragedy spurred a debate in Canada and the US about the safety of so-called “bomb trains”, and reinvigorated the discussion about shipping oil across Canada.

The debate has become a heated one, and largely comes down to whether to build large pipeline projects amid an uptick in the amount of volatile crude oil moved by rail. Both pipeline and oil by rail proponents argue their methods of transport are safe. Meanwhile, environmental groups argue both methods inevitably lead to spills or explosions, and that the oil should stay in the ground, while Canada should beef up its focus on renewable energy.

According to Transport Canada’s own data, crude oil moved by rail has increased dramatically in Canada over the past decade, from only four carloads in 2005 to 174,000 carloads in 2014.

In the case of Lac Megantic, an investigation showed a complex series of errors allowed the disaster to happen.

The goal of the recent train simulation, which used flammable liquid common in firefighter training rather than actual crude, was to improve emergency preparedness and public trust around the movement of crude and other dangerous goods by rail.

Firefighters arrived on the scene of 11 smoking tanks that had derailed. They were taught to identify the contents of the tanks and decide when it was better not to intervene, as that could make the situation worse. If tackling the fire directly, the firefighters were told to apply foam and water spray to extinguish the flames.

It’s taken two-and-a-half years to start upgrading the procedures around emergency response to train derailments involving crude, and they’re not done yet. Exercise Vulcan, as the simulation was dubbed, was a test run of those new procedures, and Transport Canada hopes to use the training in other parts of the country in the future.

“Better late than never,” one industry expert told VICE News in reaction to Transport Canada running the train derailment simulation last weekend.

It’s too soon to tell whether Lac-Mégantic has sparked real safety upgrades in the rail industry, transportation industry consultant Ian Naish said. “They’re replacing tank cars, [but] they’re doing it slowly.

“Speed of the oil trains is a big issue to me,” he continued. “I’d recommend they take another look at the maximum speed at which a train should operate because the two that went off the rails in Gogama last year were operating at around 40 miles per hour, which is 60 or 70 kilometres an hour, and since all the tank cars failed, that obviously was too fast.”

Just over a year ago, a crude oil train exploded in a fireball and derailed near the town of Gogama in northern Ontario. No injuries or deaths were reported in the March 7, 2015 explosion. It took three days to extinguish the flames.

At the time, it was the second CN train to derail near Gogama in a three-week period. Both incidents resulted in spilled crude oil.

The tankers that derailed in both Gogama accidents were the same type of Class 111 tanks that ruptured in Lac Megantic. The Transportation Safety Board, an independent agency tasked with investigating transportation disasters in Canada, has warned for years that Class 111 tanks are unsafe because they aren’t reinforced and tend to break open when they crash.

“It will be very silly for everybody, not only Quebec — any province, and any state in the United States — not to learn from what happened in Lac-Mégantic. What happened showed so many voids in the system, and so much lack of important information.”

But it won’t be until after May 1, 2017 that the notorious Class 111 tank cars — which are most susceptible to damage when they crash — will no longer be able to carry crude. Phasing in more crash-resistant tank cars will mean the Class 111s will be off the rails “as soon as practically possible,” Transport Canada spokesperson Natasha Gauthier told VICE News.

After the disaster in Lac-Mégantic, Transport Canada says it introduced strict new rules, including a two-person minimum for crews on trains carrying dangerous goods, a requirement for railway companies on federally-regulated tracks to hold valid certificates, new speed limits for trains carrying dangerous goods.

In the US, though, there’s been pushback from the railroad industry, with one representative saying there is “simply no safety case” for two-person crews.

Transport Canada also introduced more frequent audits, better sharing of information with municipalities, and increased track inspections. Plus, the agency amended the Railway Safety Act, researched crude for a better understanding of the volatile oil, and made it mandatory for some railways to submit training plans to the agency.

Since Lac-Mégantic, one improvement is that local first responders are now more aware of what dangerous goods, including crude, are travelling through their communities, Naish added.

And according to an engineering professor who witnessed first-hand the scene after the Lac-Mégantic explosion, while the railway industry is ramping up safety measures, the risk of increased shipments of oil by rail could balance those out, meaning it may not actually be any safer since Lac-Mégantic.

“Is it enough?” Rosa Galvez-Cloutier told VICE News when asked about the improved safety measures. “That’s hard to say. Zero risk doesn’t exist.”

Another major concern for Galvez-Cloutier is that when government and industry look at risk and safety, they tend do so project by project.

“Who is evaluating the big picture? Who is evaluating the whole thing?” She asked. “Government needs to put more interest and focus on the cumulative impacts of transporting dangerous goods.”

That debate is especially hot in Quebec, where the Lac-Mégantic explosion occurred. A recent poll of Quebec residents found they aren’t as likely as the rest of Canada to trust either pipelines or oil by rail.

According to a study by the Fraser Institute published last August, pipelines are 4.5 times safer than rail for moving oil — the rate of incidents for pipelines is 0.049 incidents per million barrels of oil moved, while that rate is 0.227 per million barrels of oil for trains.

“It will be very silly for everybody, not only Quebec — any province, and any state in the United States — not to learn from what happened in Lac-Mégantic. What happened showed so many voids in the system, and so much lack of important information,” Galvez-Cloutier said.

When asked if he would rather have a pipeline or a train carrying crude through his backyard, Naish laughed and said “Well I’d rather not live in the neighborhood, personally.”

“In the ideal world, the rail lines and the pipelines would avoid all populated areas all the time.”

New Oil Train Safety Regs Focus on Accident Response, Not Prevention

Repost from Center for Biological Diversity

CenterForBiolDiv_logoNew Oil Train Safety Regs Focus on Accident Response, Not Prevention

Long Phase-out of Hazardous Cars, Inadequate Speed Limits Leave Communities at Risk of Explosive Derailments

For Immediate Release, December 7, 2015
Contact: Jared Margolis, (802) 310-4054

WASHINGTON— A new transportation bill signed by President Obama includes provisions intended to improve the safety of oil trains, but leaves puncture-prone tank cars in service for years and fails to address the speed, length and weight of trains that experts point to as the leading causes of explosive derailments. The bill upgrades safety features on oil train tank cars and requires railroads to provide emergency responders with real-time information about when and where dangerous oil cargoes are being transported but doesn’t do enough to prevent oil train accidents, which have risen sharply in recent years.

“While these regulations improve our ability to prepare for oil train disasters they do virtually nothing to prevent them from ever occurring in the first place,” said Jared Margolis, an attorney with the Center for Biological Diversity who focuses on the impacts of energy development on endangered species. “Until we dramatically reduce the speed and length of these bomb trains it’s only a matter of time before the next explosive derailment sends fireballs rolling through one of our communities.”

The new regulations will require all oil train tank cars to include fire-resistant ceramic coatings and protections for protruding top fittings. The final rule issued by federal regulators in May only required oil trains with 35 loaded oil tank cars or 20-car blocks of oil tank cars to implement the new standards, and would not have required the ceramic blankets or top fitting protections for all retrofitted cars.

But experts say even the protective measures included in the new transportation regulations signed into law on Friday will do little to prevent a spill if a train derails at speeds faster than 18 mph, and oil trains are permitted to travel at 40 mph to 50 mph. And the new regulations do not require the phase-out of dangerous puncture-prone tank cars to begin until 2018, and allows them to remain in service until 2029.

“It’s irresponsible to continue to allow these bomb trains to roll through the middle of our communities and across some our most pristine landscapes,” said Margolis. “We need to quit pretending we can make these dangerous trains safe and simply ban them altogether.”

Congress has directed the U.S. Department of Transportation to continue requiring notifications to states of train routes and frequencies so communities can better prepare to respond to train derailments, explosions and oil spills. However, the new regulations do nothing to remedy the track infrastructure problems, or the excessive length and weight of oil trains, cited as leading causes of derailments. Further, it remains unclear whether the public will have access to information about these hazards.

“Keeping information on oil trains from public scrutiny is outrageous, and only serves to protect the corporate interests that care little about the risk to the homes, schools and wild areas that these trains threaten,” said Margolis. “We need to keep these trains off the tracks and keep these dangerous fossil fuels in the ground, rather than keeping the public in the dark.”

Background 

The National Transportation Safety Board has repeatedly found that current tank cars are prone to puncture on impact, spilling oil and often triggering destructive fires and explosions. But federal regulators have ignored the safety board’s official recommendation to stop shipping crude oil in the hazardous tank cars. Recent derailments and explosions have made clear that even the newer tank cars, known as CPC-1232s, are not significantly safer, often puncturing at low speeds.

The recent surge in U.S. and Canadian oil production, much of it from Bakken shale and Alberta tar sands, has led to a more than 4,000 percent increase in crude oil shipped by rail since 2005, primarily in trains with as many as 120 oil cars that are more than 1.5 miles long. The result has been oil spills, destructive fires, and explosions when oil trains have derailed. More oil spilled in train accidents just in 2013 than in the 38 years from 1975 to 2012 combined.

The Center for Biological Diversity is a national, nonprofit conservation organization with more than 900,000 members and online activists dedicated to the protection of endangered species and wild places.
