Oil train fires require SWAT teams, veteran firefighters tell states

By Curtis Tate  |  McClatchy Washington Bureau  |  June 17, 2014

— A pair of Texans with decades of firefighting experience is encouraging state and local government leaders to consider establishing SWAT-like response teams for crude oil train fires.

A series of derailments of trains loaded with crude oil in the past year has exposed numerous safety vulnerabilities, including the integrity of the rail cars, the condition of the tracks and the way the trains are operated.

It’s also revealed a yawning gap in emergency response. Most fire departments across the country are simply not trained or equipped to fight the enormous fires seen in recent derailments.

“Emergency response is the most difficult part,” said Bob Andrews, founder and president of the San Antonio-based Bob Andrews Group, who has both firefighting experience and knowledge of the rail industry.

Groups representing firefighters, fire chiefs and emergency management agencies have testified in Congress in recent months that derailments such as those in Quebec, Alabama and North Dakota are beyond their response capabilities.

“There’s only so much training you can do,” said Sam Goldwater, Andrews’ business partner. “Our first responders are pretty much maxed out.”

Andrews and Goldwater said they’ve received a favorable response so far from the state and federal officials they’ve approached. Several states have expressed interest in their plan, but a proposal for a specialty fire department in the Philadelphia region is the furthest along. They envision for their proposal to be a mix of public and private funds.

“We’re optimistic that we’ll be able to work something out in Pennsylvania,” Andrews said after a recent meeting with state officials.

Entire trains of tank cars loaded with crude oil snake through Pennsylvania’s capital city every day, bound for refineries and terminals along the East Coast. The trains carry Bakken crude oil from North Dakota and western Canadian tar sands oil to a cluster of refineries and barge terminals in the Philadelphia area.

Andrews and Goldwater say that airports and refineries have their own firefighting teams with special expertise and equipment. And, they say, that’s precisely what’s demanded by the rise in crude oil shipments by rail.

“You need the airport idea,” Goldwater said, “but you need it for the 1,400 miles between North Dakota and the Delaware River.”

In March testimony before a Pennsylvania House of Representatives committee, Andrews said that the nation’s 783,000 volunteer firefighters are dedicated to their work. But according to the National Volunteer Fire Council, their ranks have declined 13 percent since 1984.

“It is not fair for the community, at the local or state level, to create an environment where well-meaning volunteers will feel compelled to commit themselves to conducting highly-hazardous operations, that they are neither trained, nor equipped to perform,” Andrews testified.

One such incident took place in West, Texas, in April 2013. A massive explosion at a fertilizer storage facility killed 11 firefighters from five departments. In July last year, a 72-car train of Bakken crude oil rolled away and derailed at high speed in the town of Lac-Megantic, Quebec. The inferno killed 47 people and leveled much of the business district.

“Volunteer fire fighters and emergency response personnel being thrust into catastrophic events without adequate training or resources is a widespread problem that needs to be addressed,” wrote the National Transportation Safety Board after a toxic chemical leak from a rail car in November 2012 in Paulsboro, N.J.

Tim Burn, a spokesman for the International Association of Fire Fighters, said that a broad-based training program was still the best approach.

“It is the duty of government to provide the resources needed for hazmat response,” he said, “and this public safety discussion should not be driven by profit motive.”

Goldwater said he and Andrews expected a return on their investment. However, he added, if anyone wanted to make lots of money, “this is not the thing to do.”

So far, the impulse of government and industry has been to simply fund more training for emergency personnel. But Andrews said that might not be the most effective approach. The firefighting profession experiences an attrition rate of about 20 percent a year. Call volumes have increased, putting more pressure on volunteer and career firefighters alike. It’s difficult for volunteers with full-time jobs to take off time for training, and most departments can’t afford to pay for it.

The Association of American Railroads, the industry’s leading advocacy organization, has offered to train 1,500 emergency responders at its rail testing facility in Pueblo, Colo. But with the random and rare nature of train derailments, the odds aren’t good that a limited number of trained personnel scattered across the country will be where they’re needed when something happens.

Andrews and Goldwater say their plans would be geographically tailored. Philadelphia is a major destination for crude oil, so its response needs may be different from places such as Albany, N.Y., or Sacramento, Calif., where oil trains pass through.

Derailment of Canadian National freight train at Plaster Rock, New Brunswick, 7 January 2014

DORVAL, QC, June 12, 2014 /CNW/ –  June 12, 2014

The occurrence

On 7 January 2014, a Canadian National freight train was travelling from Toronto, Ontario to Moncton, New Brunswick, with 122 cars, 3 head-end locomotives and 1 remote locomotive. On the main track near Plaster Rock, New Brunswick, 19 cars and the remote locomotive derailed.  Nine of these cars were carrying crude oil and liquefied petroleum gas. There were no crew injuries. Approximately 150 people near the accident site were evacuated due to the resulting fire.

While passing by a Wayside Inspection System (WIS), the crew received an alarm. Following normal procedures, the train was slowed down while minimizing in-train forces. However, before the train stopped, the rail cars began to derail resulting in a brake pipe separation and the application of the emergency brakes. Once the train came to a full stop, the conductor walked back towards the derailment site and found a broken wheel on the 2nd axle of the 13th car. This axle had derailed, with both wheels positioned inside the track gauge.

Work Completed to Date

TSB investigators and specialists from the TSB Engineering Lab have completed the field phase of the investigation. This includes the collection of the locomotive event recorder data, the results of previous wayside inspections, initial train inspection, and inspection of the track.  The tank cars were photographed and documented for further analysis.

The broken wheel found at the occurrence site was documented and shipped to the TSB Engineering Lab for testing. Information was collected from the railway company, and officials and witnesses have been interviewed.

What We Know

The broken wheel failed due to fatigue. A crack initiated at a porosity and travelled under the running surface of the wheel which caused a shattered rim. The subject wheel was manufactured in 1991 and met the material requirements for that time period.  Wheels manufactured today undergo an ultrasonic inspection of the tread area to check for areas of porosity. This inspection procedure is carried out to detect and prevent wheels with significant areas of porosity, such as found in the subject wheel, from being placed into service.

Track damage occurred as a result of the derailed wheels battering the base of the rail. Subsequently, multiple rail fractures were found between the initial point of derailment and the derailment site.

Two of the tank cars were the primary source of the released oil that created the fire.  Both were older Class 111 tank cars, built in 1984 and 1996. The punctures in the head portion of the tank cars were most likely due to impacts with the adjacent tank car coupler assembly.

Three CPC-1232 (design specification for Class 111 cars introduced in 2011) tank cars also derailed and were examined by the TSB team. One car was essentially undamaged, while another car had some damage associated with sliding on its side after derailing. Neither of these tank cars released product. The third CPC-1232 car did not initially release product. However, this car came to rest in the pool fire, resulting in the eventual degradation of the bottom outlet valve gasket and a small release of product.

Next steps

Work continues as this ongoing investigation is in the examination and analysis phase. Investigators will interview the train crew to confirm further details.  The team will review the history of the wheel as well as its manufacturing process and look closely at the effectiveness and adequacy of Wayside Inspection Systems and other inspection methods to detect problems with wheels and axles in service. Lab work continues on the detailed examination of the damage to tank cars in order to draw conclusions about their performance. Once this phase is complete, the report writing phase will commence.

Communication of Safety Deficiencies

Should the investigation team uncover safety deficiencies that present an immediate risk, the Board will communicate them without delay so they may be addressed quickly and the rail system made safer.

The information posted is factual in nature and does not contain any analysis.  Analysis of the accident and the Findings of the Board will be part of the final report. The investigation is ongoing.

NTSB crash analysis in Lynchburg derailment slow, deliberate

NTSB says train cars being analyzed in Lynchburg derailment investigation

Train Derailment.JPEG-050.1
Associated Press | National Transportation Safety Board lead investigator James Southworth said it’s too early to say if weather was a factor in Wednesday’s oil train derailment in Lynchburg.

Federal officials continue to sift through a mountain of information in the Lynchburg train derailment, lead investigator Jim Southworth said.

Southworth, of the National Transportation Safety Board, was among some 80 federal, state and local officials who attended a rail safety roundtable organized Monday by U.S. Sen. Mark Warner.

Southworth was not one of the speakers, but in an interview afterward he said the investigation into what caused the April 30 train derailment in Lynchburg is continuing at a slow and deliberate pace.

Southworth said officials will review CSX’s maintenance and inspections records going back months.

In addition, the team will do a 3-D scan, inside and out, of the oil tanker that ruptured and send pieces of it off to a lab for metallurgical testing.

Other tankers in the 105-unit train that derailed will be scanned as well to compare their performance to the ruptured unit.

Southworth said it is too early to comment on what may have caused the derailment that upset 17 oil tanker cars, three of which fell into the James River.

He said Monday he hoped to complete the investigation in a year or less.

“There is a lot of interest in what happened here because of the type of tanker cars,” he noted. “It’s going to be scrutinized quite deliberately.”

The train that derailed in downtown Lynchburg contained a mix of older and newer model oil tankers, but the car that ruptured was a newer model intended to be safer in the event of an crash.

The derailment, which sparked a large fire on the river but caused no injuries, has made Lynchburg part of a national debate on the best way to ship crude oil in the country.

So far, there has been no evidence the derailment was caused by operator error, Southworth said. He declined to comment on other possibilities and said the investigation still is in the fact-gathering stage.

Investigators no longer are working on-site at the derailment scene, but continue to gather information and analyze the train cars and pieces of the damaged track.

Setting the record straight on the oil industry studies of Bakken crude by rail

Industry tests of oil train dangers need scrutiny, U.S. officials say

By Patrick Rucker  |  WASHINGTON, June 2, 2014

(Reuters) – Oil industry studies concluding that Bakken crude oil is safe to move by rail under existing standards may underestimate the dangers of the fuel and should not be the last word, U.S. lawmakers and industry officials said on Monday.

In the past year, several doomed oil trains originated from North Dakota’s Bakken region, including a shipment that jumped the tracks and burst into flames in Lynchburg, Virginia, on April 30. Last July, a fiery derailment destroyed the center of the village of Lac-Megantic, Quebec, killing 47 people.

Two industry-funded studies conclude Bakken fuel is rightly classed as a flammable liquid that can safely move in standard tank cars. The cargo is nothing akin to flammable gasses like propane that must move in costlier, heavier vessels, the oil industry has said.

But the industry findings hinge on incomplete and out-of-date methods for determining vapor pressure, an important indicator of volatility, that may miss the true dangers of Bakken fuel, according to several industry officials.

Lawmakers say they expect regulators to scrutinize the industry’s findings.

“These studies should be taken with a grain of salt,” said Senator Charles Schumer, Democrat of New York, a state that is a major pass-through point for Bakken fuel.

One study released May 20 by the North Dakota Petroleum Council (NDPC) collected samples with open bottles rather than a precision instrument, known as a floating piston cylinder, that is being adopted by the industry.

Gas can escape with bottle sampling and such tests are unreliable, said the Canadian Crude Quality Technical Association, a trade group.

“We would consider the data suspect,” the group said.

ASTM, an international standard-setting body, last month deemed the floating piston cylinder the right tool for Bakken fuel samples. Open bottle samples can skew vapor pressure nearly 10 percent lower, according to research from Ametek, which manufactures testing equipment.

Industry officials say that any underestimation of vapor pressure would be negligible.

Vapor pressure results did not exceed 15 pounds per square inch (psi) in the NDPC report.

A separate study by the American Fuel and Petrochemical Manufacturers (AFPM) returned readings below 17 psi.

The threshold pressure for flammable gas is 43 psi under those same conditions.

Rich Moskowitz, general counsel for the AFPM, the refining industry trade group, said its report “clearly found that Bakken crude oil is properly transported as a flammable liquid. That’s the bottom line.”

Industry officials note that the U.S. Department of Transportation has not issued any of its own findings on Bakken fuel despite collecting samples since the summer.

The issue will likely be raised on Tuesday at a panel of the Senate Commerce Committee which will feature testimony from railroad regulators, among others.

“It is my hope that any private data collection and studies on this issue will be highly scrutinized,” said Senator Cory Booker, Democrat of New Jersey, who sits on the panel.
