Minnesota fire crews ‘ill-prepared’ for any oil train catastrophe

Size of trains and N.D. blast make disaster prep a priority.

Six trains with 100 or more crude oil tank cars pass through the Twin Cities every day, and if one of them wrecks, state and local emergency responders don’t have the equipment needed to put out a catastrophic fire, state and local officials say.

To fight a major oil-train fire, local fire departments would need help from railroad emergency crews, officials said. That was the case in the Dec. 30 derailment, explosion and fire of an oil train near Casselton, N.D. Massive amounts of fire-suppressing foam, rather than standard water hoses, are needed to extinguish raging tank-car fires.

“There isn’t a fire department that has that much foam right now,” Jim Smith, assistant chief of operations for the St. Paul Fire Department, said in an interview Tuesday. Smith joined other emergency responders to discuss the issue last week with BNSF Railway Co., the largest North Dakota crude oil hauler.

BNSF and Canadian Pacific, the other regional crude oil hauler, have robust firefighting capabilities and have long worked with local fire departments on emergency response efforts. But some Minnesota officials say first responders need their own capability to fight a major crude oil fire involving multiple tank cars in a populated area.

“We are ill-prepared for this,” said state Rep. Frank Hornstein, DFL-Minneapolis, who is preparing legislation with Sen. Scott Dibble, DFL-Minneapolis, to address shortcomings in the state’s ability to cope with crude-oil emergencies on railroads or pipelines. “This is overwhelming the state right now.”

Worries about Minnesota’s rail-disaster response have emerged as Congress is studying rail safety after recent accidents, including the July crash of a North Dakota oil train that killed 47 people in Lac-Mégantic, Quebec. On Thursday, the U.S. Senate Commerce Committee’s subcommittee on transportation will hold a hearing on rail safety, and a House committee will follow with a hearing later this month.

State is major way point

North Dakota, now the second-largest oil producing state, relies on rail to ship 70 percent of its nearly 1 million barrels per day of crude oil. Much of it gets loaded onto long “unit trains” that go from North Dakota to East Coast or Gulf Coast refineries.

This crude-by-rail business didn’t exist five years ago. Now, Minnesota is a major way point for these shipments. On average, eight oil trains of about 110 cars each pass through Minnesota daily, with six of them going through Minneapolis and St. Paul, said Dave Christianson, who oversees freight and rail planning for the Minnesota Transportation Department. All of the trains, including about two a day that go south through western Minnesota, pass through many smaller towns, he said.

“We have a definite risk associated with the movement,” Christianson said.

Crude oil now is the most common hazardous material on Minnesota railways, followed by ethanol, which is shipped through the Twin Cities on 70-car trains at the rate of about one per day, he said. Tank cars carrying chlorine and anhydrous ammonia have long been considered risks, but they aren’t packed together in dedicated unit trains.

MnDOT lacks a response team for rail petroleum accidents, Christianson added. Yet the agency has five experts who respond to the more common tanker truck accidents on highways involving hazardous materials, he said.

Hornstein said Minnesota needs its own responders and equipment to rapidly deploy in rail emergencies. He said the state House Transportation Finance Committee, which he leads, also will hold a hearing on the issue early in the legislative session, which begins this month. He’s considering a fee on railroads to pay for the program, with a cost that has not yet been determined.

More equipment needed

Smith, of the St. Paul Fire Department, said Minnesota emergency responders not only lack enough firefighting foam to immediately attack a multiple-tanker fire, they also don’t have equipment to spray large amounts of foam at tank cars.

“We have over 500 gallons of foam, and that would be a drop in the bucket if one of these trains were to go,” Smith said.

If an oil train exploded and caught fire in St. Paul, Smith said, the fire department initially would focus on evacuating people and setting up an exclusion zone, and rely on railroads or others to assist with fighting the fire. Minneapolis fire officials did not respond Tuesday to requests to comment on their plans.

BNSF, Canadian Pacific and Union Pacific, which hauls ethanol in Minnesota, said they have firefighting crews across their rail networks. BNSF, for example, said it has more than 200 “hazmat’’ responders at 60 locations. Railroads also have offered free training to local fire departments and say they plan to offer more.

“We take the issue of safety seriously — it is a priority of our railroad,” said Ed Greenberg, a spokesman for Canadian Pacific, which has its U.S. headquarters in Minneapolis.

BNSF spokeswoman Amy McBeth said the rail industry is talking to federal regulators about oil train routes, reduced train speeds where risk is greatest and other steps to address the safety concerns. The rail industry also has voluntarily toughened standards for new tank cars to make them more puncture-resistant — a step that federal regulators are talking about taking.

The National Transportation Safety Board in January recommended routing oil and ethanol trains around populated areas. But many rail experts, including Christianson, say that may be difficult because many rail lines were built to reach places like the Twin Cities.

Fred Millar, a safety consultant who has worked on rail issues in Washington and elsewhere, said rerouting trains remains a good option for crude oil shipping by rail, but it would take strong action by the federal government to make it happen.

“It is a born-yesterday industry,” Millar said of the oil-by-rail phenomenon. “Unit trains are clearly posing a unique danger.”

New design for safer tank cars

New method will optimize car design for safer hazmat transport by rail

Transportation and structural engineering researchers are teaming up to develop an analytical method to measure the safety performance of railroad tank cars. Their techniques will be used to establish new industry standards to ultimately reduce the risk of transporting hazardous materials (hazmat) by rail.

“Although 99.998 percent of rail hazmat shipments reach their destination without a release caused by a train accident, potential tank car releases from train accidents could lead to severe consequences, especially if they happen in highly populated areas,” said M. Rapik Saat (BS 03, MS 05, PHD 09), a research assistant professor in the Rail Transportation and Engineering Center (RailTEC).

Saat and his colleague Christopher P.L. Barkan, professor and executive director of RailTEC, are working with Junho Song and Paolo Gardoni, both associate professors in structural engineering, to understand how new tank car designs will perform in accidents.

“A series of catastrophic tank car accidents in the 1960s and early 1970s led to several new safety features and the compilation of databases of information to measure and predict the safety of cars in service,” Barkan said. “As these databases were expanded and refined, it became possible to assess which combinations of changes in tank car safety design were most likely to maximize safety benefits. As part of a project we are finishing up during summer 2013, we updated a statistical model to evaluate tank car safety design using all the new accident information gathered since 1995. We were able to provide significant insight into the effects of some train operational factors, such as speed, that may be related to potential safety improvements that were not previously recognized because of a lack of quantitative information.”

While statistical models have been useful to evaluate existing tank car designs, the ongoing interdisciplinary collaboration between CEE’s railroad and structural engineering groups will pave the way for development of an analytical model to bridge statistical and analytical modeling (i.e. finite element analysis) approaches. For example, the interdisciplinary approach adds the ability to assess potential benefits of using new steel materials and/or structural configurations.

Tank car safety design optimization needs to consider the tradeoff between safety and efficiency, Saat said.

“For example, if you increase a tank car’s thickness, you may make it safer, but you decrease its capacity, and therefore may need more tank cars to carry the same amount of material. Our goal is to help industry find the optimal designs,” he said.

The development of this new analytical model is driven by industry and will be used for policy making.

“For example, with a new tank car design, they will do physical testing and finite element modeling to come up with the puncture energy and then translate the puncture energy to determine potential rate of release with a certain level of uncertainty,” Saat said. “This will advance the industry’s risk-based decision making to ultimately reduce the risk of transporting hazmat by rail.”

The work is a collaborative effort between government agencies and private industries involved in hazmat transportation in North America and is sponsored by the Association of American Railroads, Railway Supply Institute, American Chemistry Council, Chlorine Institute and Fertilizer Institute. CEE graduate students Laura Ghosh and Xiaonan Zhou have contributed to the project as well as Stephen Kirkpatrick from Applied Research Associates and Todd Treichel of the RSI-AAR Railroad Tank Car Safety Research and Test Project. At least one structural engineering student will also join the project team this fall.

The first phase of the new analytical model is expected to be completed in 2014.

Risk and optimization models from CEE researcher Rapik Saat’s Ph.D. dissertation work were used to identify potential enhanced tank car designs to transport toxic inhalation hazard materials.

Train sprays crude oil for nearly 70 miles

 Posted: February 5, 2014

RED WING – A southbound Canadian Pacific train leaked a trail of about 12,000 gallons of crude oil Monday morning after passing through Red Wing, according to the Minnesota Pollution Control Agency.

MPCA emergency responders worked with railroad personnel throughout the day Tuesday to gauge the extent of the spill and check for environmental damage, MPCA spokeswoman Cathy Rofshus said.

She described the leak as a “light spray on the ballast rocks” that stretches for nearly 70 miles of track.

A duty officer’s report from the Minnesota Department of Public Safety says the leak started in Red Wing and continued past Winona before it was reported around 9 a.m. Monday. Crews reportedly stopped the train and fixed a missing valve or cap responsible for the spill.

Investigators spent the day Tuesday looking for areas where the oil may have pooled, but so far none has been found, Rofshus said.

WASHINGTON, Feb 4 (Reuters) – Three oil companies operating  in North Dakota were fined $93,000 on Tuesday for wrongly  classifying fuel shipments in the first sanctions since a series  of fiery derailments put the energy industry under a spotlight.

The Department of Transportation said Hess Corp,  Marathon Oil Corp and Whiting Petroleum Corp   were cited for wrongly classifying cargo tanks that were hauling  crude oil from the field to a railhead.

Fuel shipments must be designated with a hazard class to  alert emergency responders in the event of an accident. Eleven  of eighteen samples of one survey were mislabeled, the DOT said  in a statement.

“The fines we are proposing today should send a message to  everyone involved in the shipment of crude oil: You must test  and classify this material properly,” said Transportation  Secretary Anthony Foxx.

A spate of explosive derailments, including one in Quebec  last July which killed 47 people, has led to concerns over the  safety of shipping crude oil by rail and improper labeling.

Officials have already warned that some fuel found in North  Dakota’s energy patch, the Bakken, could be more volatile and  explosion-prone than other crude oil and that shippers should  take precautions.

Typically, crude oil carries a ‘hazard class 3’  classification and can be shipped in a standard tank car. The  shipments are further assigned a ‘packing group’ to alert to  dangers – that portion of the shipping paper was faulty, the DOT  said.

While the DOT’s Pipeline and Hazardous Materials Safety  Administration (PHMSA) has been testing crude samples for months  and issued several industry warnings, Tuesday’s action is the  first sanction.

Phmsa Administrator Cynthia Quartersman said the fines  reflected “initial findings” and that officials would scrutinize  the corrosivity, pressure and other traits of Bakken crude.

The DOT did not specify which companies would be expected to  pay what share of the $93,000 fines but by any measure the sums  were small for large energy companies.

Officials from Hess and Marathon could not immediately be  reached for comment.

Jack Ekstrom, a spokesperson for Whiting, said that the  company had not yet been contacted by the DOT about a possible  fine.
