New Brunswick derailment: some tank cars fared better than others

Tank car upgrades effective in derailments, Canadian report shows

By Curtis Tate, McClatchy Washington Bureau, June 19, 2015

Tank car improvements required by the U.S. and Canadian governments last month should cut the risk of spills and fires in oil train accidents, Canadian investigators have concluded.

The finding came from the Transportation Safety Board of Canada’s investigation of on a derailment in January 2014 in Plaster Rock, New Brunswick.

While the report pinpointed a broken wheel as the cause, the derailment provided a rare side-by-side comparison of the performance of two different types of tank cars in use for decades on the North American rail system.

A type of tank car called the DOT-112 survived the Plaster Rock derailment with no impact damage, according to the report, released Friday. Four such cars carrying butane derailed.

In contrast, two DOT-111 cars carrying crude oil sustained punctures, spilling more than 60,000 gallons. The spilled oil caught fire.

The DOT-112 cars have features very similar to the new DOT-117 standard unveiled by regulators on May 1. Both include half-inch thick shields that fully protect both ends of the car, thicker 9/16-inch shells and thermal insulation around the tank shell enclosed with an additional layer of steel.

Typically, the DOT-111 cars have 7/16-inch shells and none of the other protections.

As McClatchy reported last year, the DOT-112 was beefed up after a series of catastrophic tank car explosions in the 1970s that killed railroad workers and firefighters and caused extensive property damage. After the 112 was upgraded, the accidents subsided.

But the DOT-111 fleet remained unchanged, even when railroads began hauling larger quantities of ethanol a decade ago, followed by crude oil five years ago.

The Canadian report lists 13 other rail accidents involving crude oil or ethanol since 2005 that illustrate the vulnerabilities of the DOT-111. Three of those derailments took place this year, including two in Ontario and one in West Virginia.

The list also includes the 2013 disaster in Lac-Megantic, Quebec, which resulted in 47 fatalities. The families of the victims and their attorneys earlier this month unanimously ratified a proposed $350 million settlement package.

The U.S. Department of Transportation last month required that new tank cars carrying crude oil and ethanol meet the DOT-117 standard beginning in October. Tank car owners, which are typically railcar manufacturers, financial firms and energy companies, must comply with a series of retrofit deadlines for DOT-111 cars that are spread out over a decade.

The oil industry says the timeline is too short, while environmentalists say it’s too long. Both have since taken the department to court.

    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.

      Firefighter battalion chief: Russian roulette on the railways

      Butte County train tracks are Bakken-free for now, but emergency responders fear a return of the volatile fuel

      What is ‘Bakken’?

      The light crude oil known as Bakken comes from fracking a geologic formation of that name under North Dakota, Montana and Canada. Less dense and with less carbon, light crudes yield more gasoline than heavier crudes, but also are more volatile.

      Trains crash. That fact hit home last week when a passenger train derailed in Philadelphia and also last year, on Nov. 26, when a cargo train derailed in the Feather River Canyon.

      The risk of devastation multiplies when the derailed train carries volatile crude oil. A recent spate of those accidents has garnered national attention, too, prompting the U.S. Department of Transportation (DoT) to release new regulations governing the conveyance of flammable liquids. The measures have drawn near-unanimous opposition, though, and done little to assuage lingering local fears.

      “My constituents have raised concerns and the Board [of Supervisors] is concerned,” said Butte County Supervisor Maureen Kirk, who represents Chico. “We’re hoping that some of the legislation and some of the discussion that comes forward will make even stiffer requirements on the transport of this Bakken oil.”

      The DoT regulations came out May 1. Five days later, another oil train crashed, in North Dakota. By last Friday (May 15), both the petroleum industry and environmentalists had filed legal challenges to the DoT’s so-called “final rule.”

      The International Association of Fire Fighters also has voiced objections. Representing more than 300,000 firefighters in North America, the IAFF protested a provision that allows railroads to keep the contents of their trains confidential—under the banner of national security.

      Russ Fowler, battalion chief with Cal Fire Butte County and coordinator of the local Interagency Hazardous Materials Team, has additional concerns. DoT regulations phase out tank cars that are not up to the current safety standard, rather than pull them off the rails for retrofitting or retirement. Transportation Secretary Anthony Foxx has argued that the alternative would result in increased oil-tanker traffic on highways.

      Fowler says one particular railcar commonly used to carry volatile Bakken crude oil, the DOT-111, “just [wasn’t] designed for that product.” Since railroads have until 2018 to get those cars up to standard, “we have three years of potential Russian roulette on our hands if light crude oil is transported down the Feather River Canyon like it was done last fall.”

      Cal Fire has communicated with BNSF Railway, Fowler said, and has been told no crude oil deliveries have come through Butte County this year. “I have no reason not to believe them,” he added, though he’s seen DOT-111s riding on Chico tracks.

      Lena Kent, BNSF’s spokeswoman for California, confirmed by email that “we are not currently transporting Bakken crude in your county.” She also wrote: “We do provide information to the Office of Emergency Services in California.”

      That’s in contrast with last year, when train cars carrying millions of gallons of the explosive oil, reportedly around one shipment per week, did make their way way along the Feather River Canyon. Experts tie the reduction of imports to a reduced demand for the fuel, a lighter type that’s similar to gasoline and thus extremely volatile.

      While Cal Fire dreads the prospect of an urban crash, the Feather River Canyon presents a distinct set of frets.

      Train tracks head into remote areas that are difficult for emergency responders to reach. Access roads don’t always run adjacent to the rail route—not even parallel in certain spots. Depending on where a crash occurred, spilled oil could contaminate the Feather River and Lake Oroville—a major source of water for California—or could start a forest fire should it ignite.

      Even without a blaze or river release, “it would make an ugly, oily mess in the canyon,” Fowler said. “It would be a terrible environmental disaster.”

      Butte County supervisors articulated such concerns to the California Public Utility Commission and the Governor’s Office of Emergency Services, before the DoT released its regulations. OES responded by saying the state is investing in “purchasing new Type II hazardous material emergency response units” and in “local training specific to … rail safety incidents.”

      For Supervisor Doug Teeter, the board chair who represents the Ridge, that’s little assurance. He has a powerless feeling—believing “it’s just a matter of time” before an accident happens locally, yet knowing “as a county we have no control” over the rails.

      “We’re at the mercy of the federal regulators,” he continued. “All we’re really getting is a little response on improved training and equipment. That is not nearly enough to handle a 100-car spill.”

      Either in populated or unpopulated areas.

      “We as a hazmat team plan for worst-case scenarios,” Fowler said. “Just because you plan for a worst-case scenario doesn’t mean you can mitigate the worst-case scenario, because there are things that can happen that are so catastrophic that it would overwhelm local resources until more regional or statewide resources could come in to help.”

      Should legal challenges fail, and in the absence of local authority, a remedy to the DoT regulations remains: Congress. Teeter recently met with a representative of Sen. Barbara Boxer. Meanwhile, North State Congressman John Garamendi has introduced legislation to make light crude safer for rail transport.

      Teeter encourages constituents to write congressional representatives and senators. He finds encouragement even in the controversial DoT regulations, which arose amid an uproar.

      “Maybe now we’ll have a voice,” Teeter said. “Maybe something can happen.”

        EXCLUSIVE-Tesoro building crude railcars stronger than new US rules require

        By Kristin Hayes, May 18, 2015 4:59pm BST

        (Reuters) – U.S. refiner Tesoro Corp has ordered new crude oil railcars with features that surpass safety standards that federal regulators set this month, executives told Reuters.

        The 210 tank cars being built in northern Louisiana are so-called pressure cars, with the same design as those that carry liquid petroleum gases such as propane and butane, gas cargoes that are more flammable than crude oil.

        They will be delivered in the coming months after being ordered in early 2014.

        The new federal rules for all crude and ethanol railcars built after Oct. 1 of this year do not require strength to the level of a pressure car but are stronger than the standards adopted by the industry in 2011.

        Tesoro, like other oil-by-rail players, knew the federal standards were coming and the basics of what they would likely be. But the company went further with a stronger car, “which is the primary thing we control,” C.J. Warner, Tesoro’s head of strategy and business development, told Reuters.

        The order was a sign the refiner wanted to get ahead of the coming regulations and avoid potential capacity bottlenecks at companies that build tank cars as shippers must now renovate their fleets.

        Booming North American onshore production spurred sharp growth in moving oil by rail, particularly for U.S. West and East coast refiners which otherwise must depend on more costly imports. No major crude pipelines move oil from the Midcontinent west across the Rocky Mountains or east through the Appalachians and densely populated northeastern states.

        Fiery derailments, caused in some cases by track failures, have become more frequent as oil-by-rail and crude-only trains carrying 100 cars or more went from nearly nothing five years ago to more than 1 million barrels per day late last year.

        Opposition to moving oil by rail spiked on safety concerns, prompting the U.S. Department of Transportation and Canada to impose new railcar safety standards.

        Tesoro isn’t the only refiner that didn’t wait for word from the U.S. DOT to order stronger cars.

        Phillips 66 confirmed to Reuters that it also last year ordered 350 non-pressurized new cars that mostly match the new DOT standard. Those cars will be delivered by year-end, the company said.

        THICKER HULLS

        Both sets of new cars have 9/16-inch-thick hulls, steel shields on the front and back and protections for valves and fittings where crude goes in on top and drains out the bottom, as the new rules require, company executives said. Tesoro’s design modifies those fittings to handle crude rather than just LPGs.

        Tesoro’s cars also have test pressure specifications of 200 pounds per square inch of internal pressure, twice that for non-pressurized cars. A test pressure is typically 20 to 40 percent of how much pressure it would take for the railcar to burst.

        That level of test pressure is standard for cars that transport LPGs or highly poisonous substances such as hydrogen cyanide, according to the Association of American Railroads.

        “When we saw the design, we were very comfortable that it would meet the new standards that we anticipated,” John Hack, Tesoro’s head of rail operations, told Reuters.

        For Tesoro, which hopes to build the largest oil-by-rail facility in the United States in Washington state, it’s an investment in safety and continued access to cheaper North American crudes.

        “It’s very important to us to continue to transport North American crude and get it from the Midcontinent out to the West Coast where it competes very nicely with the foreign crudes,” Warner said.

        RETROFITS?

        By last year most refiners, including Tesoro and Phillips 66, no longer accepted shipments in older, weaker railcars such as those used on a runaway crude train that careened into the small Quebec town of Lac Megantic in mid-2013, killing 47 people.

        Early last year Tesoro needed to replace the last of its older cars and worked with its builder, Berkshire Hathaway Inc’s Union Tank Car, to develop the new design, Warner said.

        Tesoro and Phillips 66 aim to use their newest cars in crude trains before deciding whether to order more. Both companies’ fleets meet the 2011 industry standard for cars with 7/16-inch-thick hulls and reinforced valves.

        Those 7/16-inch cars don’t have to be thrown out, but to move in crude-only trains, they will need added protections, including ‘jackets’, or an extra layer of steel around the tank, according to the DOT rules.

        Neither Tesoro’s nor Phillips 66’s new cars are equipped with specialized brakes that the DOT said crude-only trains must have starting in 2021 or be held to 30 miles per hour. An oil industry trade group is challenging that provision in court.

        Hack said Tesoro is talking with Union Tank Car on possibly outfitting crude railcars to add enhanced brakes before the 2021 deadline.

        “We have some time to make that decision,” he said.
