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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Obama admin to give companies more time to upgrade DOT-111 & C-1232 tank cars

Revised Oil-Train Safety Rule Said to Delay Upgrade Deadline

by Jim Snyder, February 12, 2015

(Bloomberg) — The Obama administration revised its proposal to prevent oil trains from catching fire in derailments, giving companies more time to upgrade their fleets but sticking with a requirement that new tank cars have thicker walls and better brakes.

The changes, described by three people familiar with the proposal who asked not to be identified because the plan has not been made public, are in proposed regulations the U.S. Transportation Department sent to the White House last week for review prior to being released.

The administration is revising safety standards after a series of oil-train accidents, including a 2013 disaster in Canada that killed 47 people when a runaway train derailed and blew up. Earlier this month a train carrying ethanol derailed and caught fire outside of Dubuque, Iowa. No one was hurt.

Companies that own tank cars opposed the aggressive schedule for modifying cars in the DOT’s July draft, saying it would have cost billions of dollars and could slow oil production. That plan gave companies two years to retrofit cars hauling the most volatile crude oil, including from North Dakota’s booming Bakken field.

Railroads and oil companies fought the brake requirement and proposed a standard for the steel walls that was thinner than suggested by the agency.

‘Too Long’
Karen Darch, the mayor of the Chicago suburb of Barrington, Illinois, and an advocate for safer cars, said she was encouraged that the rules included stronger tank cars and upgraded brakes. She disagreed with adding years to the retrofit deadline.

“Taking more time on something that’s already taken too long is problematic,” Darch said Thursday in a phone interview.

Officials in the President Barack Obama’s Office of Management and Budget could change the proposal before the final version is released, probably in May. Darius Kirkwood, a spokesman at the Pipeline and Hazardous Materials Safety Administration, the Transportation Department unit that wrote the rule, said he couldn’t comment on a proposed rule.

“The department has and will continue to put a premium on getting this critical rule done as quickly as possible, but we’ve always committed ourselves to getting it done right,” Transportation Secretary Anthony Foxx said this month in a statement about the timing of the safety rule.

Rolling Deadlines
The current proposal would require companies to first upgrade tank cars known as DOT-111s, which safety investigators have said are prone to puncture in rail accidents, according to one of the people. Cars with an extra jacket of protection would remain in use longer before undergoing modifications, according to one of the people.

A newer model known as the CPC-1232, which the industry in 2011 voluntarily agreed to build in response to safety concerns, would have a later deadline than the DOT-111s for modification or replacement, three people said.

The CPC-1232s have more protection at the ends of the cars and than the DOT-111s and a reinforced top fitting.

The draft rule also would require that new tank cars be built with steel shells that are 9/16th of an inch thick, the people said. The walls of the current cars, both DOT-111s and CPC-1232s, are 7/16th of an inch thick.

A joint proposal from the American Petroleum Institute and the Association of American Railroads argued to set the tank-car shell thickness at half an inch, or 8/16ths.

Company Lobbying
Railroads and oil companies also lobbied against a proposal that the trains have electronically controlled pneumatic brakes, which are designed to stop all rolling cars at a same time.

The Association of American Railroads in June told Transportation Department officials that the electronic brakes would cost as much as $15,000 for each car and have only a minimal safety impact.

Trains often haul 100 or more tank cars filled with crude. These trains have increasingly been used to haul crude as oil production has boomed in places, like North Dakota, that don’t have enough pipelines.

Rail shipments of oil surged to 408,000 car loads last year from 11,000 in 2009.

A controversial proposal by the Valero Refining Company in Benicia to run two 50-car crude-oil trains a day through Sacramento and other Northern California cities to its bayside refinery has hit another slowdown.

Benicia officials on Tuesday said they have decided to redo some sections of an environmental impact analysis of the project. The city plans to release a rewritten report June 30 for public review and comment over the summer.

The city’s decision comes after numerous groups, including Sacramento leaders, state Attorney General Kamala Harris and state oil spill prevention officials, called Benicia’s review of the project inadequate.

Those critics said Benicia failed to analyze the potential impacts of an oil spill and fire in cities, waterways and rural areas along the rail line, and also did not analyze the project’s potential impacts east of Roseville in environmentally sensitive areas such as the Feather River Canyon. They also challenged Benicia’s assertion that an oil spill between Roseville and Benicia would be a once-in-a-111-year event.

Crude-oil rail shipments have come under national scrutiny in the last year. Several spectacular explosions of crude oil trains, including one that killed 47 in a Canadian town in 2013, have prompted a push by federal officials and cities for safety improvements.

Sacramento and Davis leaders have called on Benicia to require the Union Pacific Railroad to give advance notice to local emergency responders, and to prohibit the railroad company from parking or storing loaded oil tank trains in urban areas. Local officials want the railroad to use train cars with electronically controlled brakes and rollover protection. Sacramento also has asked Benicia to limit Valero to shipping oil that has been stripped of highly volatile elements, including natural gas liquid.

Valero officials had said they hoped to begin receiving crude oil by trains early this year. In an email to the Bee, Valero spokesman Chris Howe said, “The proposed steps (by Benicia) are part of the process which we expect will allow the city to grant us a use permit for the project.”

In a hearing Tuesday in the U.S. House of Representatives in Washington, D.C., Jack Gerard, the president and CEO of the American Petroleum Institute, lamented that lengthy reviews were holding up the development of the country’s energy resources, including the Keystone XL pipeline, which has been under review by the State Department for seven years.

Gerard said some opponents were turning the process into a referendum on fossil fuels. “What we’re seeing across the country today is there’s a small group of individuals who are using permitting processes and infrastructure as surrogates to stop economic activity that they disagree with,” he told the House Subcommittee on Railroads, Pipelines and Hazardous Materials.

So it turns out Bakken oil is explosive after all

Producers in North Dakota’s Bakken oil fields have been told to make crude is safer before being shipped by rail
By Chris Sorensen, December 10, 2014

Oil TrainsAfter years of insisting oil sucked from North Dakota’s Bakken shale wasn’t inherently dangerous, producers have been ordered to purge the light, sweet crude of highly flammable substances before loading it on railcars and shipping it through towns and cities across the continent.

State regulators said this week that the region’s crude will first need to be treated, using heat or pressure, to remove more volatile liquids and gases. The idea, according to North Dakota’s Mineral Resources Director Lynn Helms, wasn’t to render the oil incapable of being ignited, but merely more stable in preparation for transport.

It’s the latest regulatory response to a frightening series of fiery train crashes that stretches back to the summer of 2013. That’s when a runaway train laden with Bakken crude jumped the tracks in Lac-Mégantic, Que., and killed 47 people in a giant fireball. In the accident’s immediate aftermath, many experts struggled to understand how a train full of crude oil could ignite so quickly and violently. It had never happened before.

Subsequent studies have shown that Bakken crude, squeezed from shale rock under high pressure through a process known as hydraulic fracturing, or “fracking,” can indeed have a high gas content and vapour pressure, as well as lower flash and boiling points. However, there remains disagreement about whether the levels are unusual for oil extracted from shale, and whether the classifications for shipping it should be changed.

Still, with more than one million barrels of oil being moved by rail from the region each day, regulators have decided to err on the side of caution and implement additional safety measures. For producers, that means buying new equipment that can boil off propane, butane and other volatile natural gases. Under the new rules, the Bakken crude will not be allowed to have a vapour pressure greater than 13.7 lb. per square inch, about the same as for standard automobile gasoline. Regulators estimate that about 80 per cent of Bakken oil already meets these requirements.

The industry isn’t pleased. It continues to argue that Bakken oil is no more dangerous than other forms of light, sweet crude, and is, therefore, being unfairly singled out. It has also warned that removing volatile liquids and gasses from Bakken crude would result in the creation of a highly concentrated, highly volatile product that would still have to be shipped by rail—not to mention additional greenhouse-gas emissions. It goes without saying that meeting the new rules will also cost producers money—at a time when oil prices are falling.

In the meantime, regulators on both sides of the border are taking steps to boost rail safety by focusing on lower speed limits, new brake requirements and plans to phase out older, puncture-prone oil tank cars. Earlier this year, Transport Minister Lisa Raitt said Canada would be “leading the continent” on the phase-out of older DOT-111 tank cars, which have been linked to fiery crashes going back 25 years. There are about 65,000 of the cars in service in North America, about a third of which can be found in Canada.
