Tougher Tank Cars Too Slow in Coming: NTSB’s Sumwalt

"A year after the Mount Carbon crude oil train fire, residents there know that they narrowly escaped their town becoming the American Lac-Mégantic – an outcome of a fiery derailment that could still happen at any moment," NTSB Board Member Robert Sumwalt wrote Feb. 18, 2016.

Two important rail safety changes for which the National Transportation Safety Board has been waiting are not yet realized, and a Feb. 18 post on NTSB’s Safety Compass blog by board member Robert L. Sumwalt calls for them to be achieved.

The two are changing over U.S. railroads’ DOT-111 tanker cars that carry crude oil and ethanol so they meet the more stringent DOT-117 standard and implementing positive train control.

But DOT has decided to give railroads until 2025 to convert to the DOT-117 standard (which includes tank head shields, thicker shell material for increased puncture resistance, tank jackets and thermal protection systems with reclosing high-capacity pressure relief devices, and stronger protection for bottom outlet valves and top fittings) for those cars and until 2029 for tank carrying other flammable liquids, Sumwalt wrote.

As for positive train control, it was required to be implemented by 2015, but late last year the deadline was extended to 2018. “Some railroads have already advised the FRA they will need an extension to the extension, pushing implementation to late 2020,” Sumwalt wrote. “It takes effort and money to make changes to enhance safety, and the NTSB applauds the efforts thus far to implement PTC. But it’s time to finish the job.”

He began the post by commenting on the Feb. 15, 2015, derailment of 27 tank cars from a 109-car crude oil unit train near Mount Carbon, W.Va. “Crude oil was released from the derailed cars and immediately ignited into a pool of fire. Emergency responders evacuated 1,100 people within a half-mile radius of the accident and allowed the fire to burn itself out,” he wrote. “All of the cars involved in the Mount Carbon accident were the enhanced DOT-111 tank cars built to the industry’s CPC-1232 standard, the best available general service tank car at the time of the accident. Yet, the fire created by two punctured tank cars resulted in 13 adjacent tank cars becoming breached when heat exposure weakened their shells, which were not equipped with thermal protection systems.”

Sumwalt listed several other derailments in the United States that involved the release of flammable materials and post-accident fires, and he cited the terrible example of the derailment of a train hauling Bakken crude oil in Lac–Mégantic, Quebec, in July 2013, killing 47 people.

NTSB would have preferred a more aggressive DOT-117 implementation schedule and awaits concerted efforts by the railroads to upgrade their existing DOT-111 tank cars in flammable liquids service to the new DOT-117 standard or relegate them to carrying less dangerous cargo, he added.

“A year after the Mount Carbon crude oil train fire, residents there know that they narrowly escaped their town becoming the American Lac-Mégantic – an outcome of a fiery derailment that could still happen at any moment,” he wrote.

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

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.

The U.S. Has An Oil Train Problem

Recipe for disaster: Put a flammable substance under pressure into a metal container, then rumble it at 50 miles an hour down a metal rail, across hundreds or even thousands of miles, through towns and cities and over bodies of water. Repeat, as necessary.

The United States is coming to the end of the costliest year on record for oil train explosions, Bloomberg News reported Tuesday, as crude oil travelling by rail has reached its highest levels ever. This past year saw a town in North Dakota evacuated after a May derailment and explosion; another major derailment and explosion in Illinois in March; and a February derailment and explosion in West Virginia, which destroyed a home, forced the evacuation of 1,000 people, and caused the governor to declare a state of emergency.

At the beginning of 2010, the United States was shipping about one million barrels of oil by rail every month. By mid-2014, though, that number was around 25 million. Imports from Canada increased 50-fold during that time. The resulting surge in accidents — including a Quebec derailment in 2013 that killed 47 people — prompted the Department of Transportation to enact new safety rules in May 2015.

But those rules didn’t prevent costs from ballooning from $7.5 million in damage in 2014 to $29.7 million in 2015, according to Department of Transportation data.

Still, carloads of petroleum products have declined significantly since their peak in December 2014, and Bloomberg reporter Mathew Philips suggests that we are unlikely to see this amount of crude by rail in the future.

The reasons for this decline are two-fold. The United States sees crude by rail mainly from two places: Alberta, Canada’s tar sands and the Bakken oil fields of North Dakota, which are affected by two very different scenarios. The Alberta tar sands are expensive to develop and are far from refineries and consumers. That means developers who have already invested will turn to rail as a way to recoup expenses, but it is not their first choice. Without available, low-cost transportation, new development in the tar sands is economically unfeasible, Oil Change International’s Lorne Stockman told ThinkProgress. According to his group’s report “Lockdown: The End of Growth in the Tar Sands,” without more pipelines, tar sands development is going to hit a wall. (In other words, the group agrees with climate activists who say the Keystone decision really will keep more oil in the ground.

But even though stopping pipeline expansion could inhibit oil extraction in Canada, it’s not so simple in the United States. Developing the Bakken fields is significantly less expensive than in Alberta, and producers have — for the past five years — had no problem using rail to bring their cheap crude to the coasts, where it competed with more expensive overseas oil. Now that overseas prices have dropped, producers are building out more pipeline infrastructure, but without it, they could still compete on the open market.)

“It’s hard to say that if you don’t build the pipe, it won’t go by rail,” Stockman said. “We’ve seen in the last five years that it does go by rail.”

He admits this is probably not what anti-pipeline activists want to hear.

“There are local issues around [pipelines], landowner issues, and I totally sympathize with that,” he said. The answer just isn’t going to be found in infrastructure. “If you want to stop production in the Bakken, you should make the producers pay for their pollution.”

The fact is, there is no safe way to transport oil. Studies have shown that while trains spill more often, pipelines spill more oil per incident. When the new regulations came out in 2014, environmentalists — and some legislators — criticized them as not going far enough. Because the realities of transporting an explosive material are pretty scary: while the new regulations lower allowable speeds, tests have shown that the cars can be punctured travelling at less than 20 miles an hour. The new speed limit is 50 miles an hour.

This week, New York Attorney General Eric Schneiderman filed a petition to reduce the pressure of crude rail cars.

“In New York, trains carrying millions of gallons of crude oil routinely travel through our cities and towns without any limit on its explosiveness or flammability – which makes crude oil more likely to catch fire and explode in train accidents,” Schneiderman said in an emailed statement. “The federal government needs to close this extremely dangerous loophole, and ensure that residents of the communities in harm’s way of oil trains receive the greatest possible protection.”

“Uprail” government agencies critical of Valero Benicia environmental report

Safety still a primary concern with Valero rail transport plan

FAIRFIELD — Most of those who provided formal comments on the revised draft environmental impact report for the Valero crude-by-rail project in Benicia focused on a need for increased safety and possible mitigation measures.

The city of Benicia Planning Department received plenty of input leading up to last week’s deadline for submitting written comments on the revised report.

The proposed project would allow Valero to transport crude oil to its Benicia refinery on two 50-car freight trains daily on Union Pacific tracks that come right through downtown Davis on their way to Benicia. The trains also pass through Dixon, Fairfield and Suisun City.

The rail shipments would replace up to 70,000 barrels per day of crude oil currently transported to the refinery by ship, according to city documents. The Valero refinery would continue to receive crude by pipeline, the city said.

Among the written comments submitted on the revised impact report was an eight-page response from the Sacramento Area Council of Governments. The agency responded on behalf of the 22 cities and six counties in its jurisdiction, including the city of Davis and Yolo County.

“Our earlier letter expressed grave concern that the DEIR concluded that crude oil shipments by rail pose no ‘significant hazard’ to our communities, and we urged the city of Benicia to revise the DEIR to fully inform decision-makers and the public of the potential risks of the project,” SACOG said in its remarks.

The agency’s response included a list of eight measures its board of directors indicated that, at a minimum, should be followed.

Those directives include advance notification to county and city emergency operations offices of all crude oil shipments; limits on storage of crude oil tank cars in urbanized areas of any size; and appropriate security for all shipments.

Other directives outlined need for support, including full-cost funding for training and outfitting emergency response crews; and use of freight cars with electronically controlled pneumatic brakes, rollover protection and other features that mitigate what the agency believes are the risks associated with crude oil shipments.

Finally, the agency calls for the implementation of Positive Train Control to prioritize areas with crude oil shipments.

Solano County Resource Management Director Bill Emlen, a former Davis city manager, noted in his response that he had no specific comment on the revised report, but that the county stands behind its initial remarks about the original draft report.

In those remarks, dated Sept. 8, 2014, Emlen said the county wanted more done to address potential derailments.

The original draft EIR admitted the project “could pose significant hazard to the public or the environment,” but minimized the chances of that happening.

“Although the consequences of such a release are potentially severe, the likelihood of such a release is very low,” the report said.

Emlen disagreed that the accident risks associated with the crude-by-rail proposal are “less than significant” without mitigation.

Valero plans to use a type of tank car designated as CPC-1232 to transport oil between Roseville and Benicia and there will be a 40 mph speed limit through federally designated “high-threat urban areas,” including cities along the route, according to the draft report.

Emlen said it appears Valero’s use of the CPC-1232 tank cars is voluntary, rather than mandatory. He also pointed out that the federal designation for high-threat urban areas extends only 10 miles east of Vallejo and 10 miles west of Sacramento, which leaves out most of Solano County.

Emlen cited a derailment and spill that took place in Virginia with a train using CPC-1232 tank cars and traveling 23 mph.

“Therefore, the use of CPC-1232 tank cars at low speeds does not alone mitigate the potential impact from a train derailment,” he said.

Other cities that submitted a written response on the revised draft included Davis, Albany, Gridley and Briggs. Other counties that responded included Yolo, Placer and Nevada counties.

An original draft EIR was issued for the project in June 2014. Benicia said it issued the revised draft EIR in response to requests made in that original report. The city released the revised document Aug. 31 for a 45-day review period. It later extended the deadline for submitting written comments from Oct. 16 to Oct. 30.

The Benicia Planning Commission also gathered public input on the revised document at a Sept. 29 meeting.

The Valero project involves the installation of a new railcar unloading rack, rail track spurs, pumps, pipeline and associated infrastructure at the refinery, according to a city report. The crude would originate at sites in North America.

Union Pacific Railroad would transport it using existing rail lines to Roseville, and from there to the refinery, the city said.
