RISKY CARGO ON MIDWEST OIL TRAINS

Amid fracking boom, cities fear explosive safety risk it can carry

BY TOM HENRY , BLADE STAFF WRITER, June 1, 2015

CHICAGO — While the global fracking boom has stabilized North America’s energy prices, Chicago — America’s third largest city and the busiest crossroads of the nation’s railroad network — has become ground zero for the debate over heavy crude moved by oil trains.

With the Windy City experiencing a 4,000 percent increase in oil-train traffic since 2008, Chicago and its many densely populated suburbs have become a focal point as Congress considers a number of safety reforms this year.

Many oil trains are 100 or more cars long, carrying hydraulically fracked crude and its highly explosive, associated vapors from the Bakken region of Montana, North Dakota, Saskatchewan, and Manitoba.

A majority of those trains also cross northwest Ohio on their way to refineries and barge terminals along the East Coast.

Derailments can lead to massive explosions, such as the one on July 6, 2013, when a runaway train derailed in Lac-Megantic, Que., just across the U.S.-Canada border from Maine. The resulting explosions and fire killed 47 people and leveled the town’s business district.

“For me to assure my community there’s no risk, I would be lying,” Aurora, Ill., Mayor Tom Weisner told reporters on the Halsted Station’s elevated platform near downtown Chicago last week. The discussion was arranged by the Institutes for Journalism & Natural Resources, a group that promotes better environmental reporting.

Authorities are concerned a rail accident would be catastrophic, as trains are carrying more heavy crude since fracking became popular.

“A derailment in or around our downtown would be absolutely disastrous,” he said.

One of Chicago’s distant western suburbs, Aurora, with 200,000 people, is the second-largest city in Illinois. Though it has fewer than one resident for every 10 in Chicago (population: 2.7 million), Aurora is somewhat smaller than Toledo, which has 281,000 residents.

Mr. Weisner, whose mayoral office overlooks tracks where many of the oil trains pass going toward Chicago, shrugged when asked about emergency planning.

“That always helps, of course. But you could have a major catastrophe before they could arrive on the scene, and that’s the truth,” Mr. Weisner said, noting the Lac-Megantic explosion on at least three occasions.

Closer to home, he said, are memories of a train explosion on June 19, 2009, in Cherry Valley, Ill., just outside Rockford.

Although that derailment involved a train carrying flammable ethanol — not an oil train — its fire killed a motorist stopped at a railroad crossing, injured seven people in cars plus two firefighters, and forced the evacuation of 600 homes.

On March 5, 21 cars of a 105-car BNSF Railway train hauling oil from the Bakken region of North Dakota derailed in a heavily wooded, rural area outside Galena, Ill.

The train erupted into a massive fireball 3 miles from a town of 3,000 people in the northwest corner of Illinois, near the Iowa and Wisconsin borders.

No deaths were reported from that incident and, like several other derailments that have resulted in explosions and fires in recent years, it occurred in a rural area.

Mr. Weisner and others fear it is a matter of time before a much higher-profile incident occurs in Chicago or some other big city where the death toll could be significant.

Shortly after he finished, an oil train moved past Halsted Station, whose tracks are flanked by high-rise apartment buildings.

Oil trains move throughout the Great Lakes region after getting filled with Bakken crude, often ending up on the East Coast.

Chicago and the rest of the Great Lakes region is “the heart of the country,” Mr. Weisner said.

“We’re always going to be at one of the highest levels of exposure,” the Aurora mayor said. “There’s no doubt about it.

Environmental activists such as Josh Mogerman, spokesman for the Natural Resources Defense Council’s Great Lakes regional office in Chicago, put the risk in more graphic terms.

“Welcome to the Bomb Train Capital of America,” he told reporters outside a coffee shop at West Maxwell and Halsted streets, three blocks north of the train station where Mr. Weisner would speak moments later.

“Of all the suite of issues I work on for the NRDC, this is the scariest,” Mr. Mogerman said. “These are moving targets going through very, very densely populated areas.”

Tony Phillips is an artist who lives in a condominium adjacent to Chicago’s Halsted Station.

He said he can hear “the rip of noise” and feel his building shudder as oil trains come by, often in the wee hours of the morning. He said he feels a “slosh effect” in the flooring from the oscillating weight of crude if he gets up in the middle of the night.

“That’s a little spooky,” Mr. Phillips said.

He and others want reforms, tighter rules, and more robust train cars, if nothing else. Some efforts are being made through tighter regulations, but critics claim they’re either not enough or being phased in too slowly.

Lora Chamberlain, spokesman for Frack Free Illinois and a new coalition called Chicagoland Oil By Rail, said vapor removal should be on the list of priorities to help mitigate the risk.

In a May 7, 2014, order, the U.S. Department of Transportation called for state emergency responders to receive more information about railroad routes handling 1 million gallons or more of Bakken crude oil per week because the number and type of railroad accidents “is startling.”

In 2013, America moved 8.3 billion barrels (348.6 billion gallons) of crude oil via pipeline — nearly 29 times the 291 million barrels (12.2 billion gallons) moved by rail, according to data from the Association of Oil Pipelines and the Association of American Railroads.

Safety experts see North America at a turning point because of the oil and gas industry’s rapid increase in hydraulic fracturing of shale bedrock, a process commonly known as “fracking” that the U.S. Energy Information Administration predicts will remain strong for at least the next 30 years.

Fracking has occurred commercially since the 1950s. The game-changer occurred less than a decade ago, when a technique developed to combine horizontal drilling with fracking made it economical to go after vast reserves of previously trapped oil and natural gas worldwide — including in eastern Ohio and western Pennsylvania, where the Utica and Marcellus shale regions meet.

Rail traffic

Railroads moved 493,126 tank-car loads of oil in 2014, a nearly 5,200 percent increase over the 9,500 tank cars that hauled oil before the fracking boom began to hit its stride in many parts of North America in 2008, according to the U.S. Department of State. Before the fracking boom, rail shipment of crude was rare and generally confined to a few isolated corridors where pipelines hadn’t been built.

Overall domestic crude production has risen 70 percent during that same period. U.S. Energy Information Administration figures show domestic oil produced at a rate of 8.5 million barrels a day in 2014, up from 5 million barrels a day in 2008.

This year, crude is expected to be produced at a rate of 9 million barrels a day, just shy of its peak rate of 9.6 million barrels a day in 1970, according to the Energy Information Administration.

“While pipelines transport the majority of oil and gas in the United States, recent development of crude oil in parts of the country under-served by pipeline has led shippers to use other modes, with rail seeing the largest percentage increase,” a Government Accountability Office report said. “Although pipeline operators and railroads have generally good safety records, the increased transportation of these flammable hazardous materials creates the potential for serious accidents.”

The agency cited a need for better U.S. Department of Transportation rules on flammability of products shipped by rail and a greater emphasis on emergency preparedness, “especially in rural areas where there might be fewer resources to respond to a serious incident.”

In its 2015 forecast, the Association of American Railroads contends railroads “are making Herculean efforts” to improve “an already safe nationwide rail network” now crisscrossing some 140,000 miles of the country.

The trade association said freight railroads plan to spend a record $29 billion in 2015 — a staggering $3 million an hour or about $79 million a day — to rebuild, maintain, and expand America’s rail network. Much of the money will go toward new equipment and locomotives, new track and bridges, higher tunnels, and newer technology.

Freight railroads are expected to hire 15,000 more people this year, continuing its upward hiring trend for an industry that employs 180,000 people, the association said.

While considering safety reforms, Congress must ensure that “any changes to public policy still allow railroads to continue private infrastructure spending and other network investments needed to meet customer demand,​” the industry group said.

Major oil train risk: bridge infrastructure – who will be the next Quebec?

Repost from FOX6Now, Milwaukee WI

“This needs to be fixed:” FOX6 finds a new “risk on the rails,” could Milwaukee be the next Quebec?

By Brad Hicks, May 12, 2015, 10:00pm


MILWAUKEE (WITI) — Last year, the FOX6 Investigators were the first to expose a new risk on the rails — a steady stream of long oil trains trekking across the state from North Dakota. The crude oil they carry from what’s called “The Bakken” is highly explosive. Since then, there has been growing public concern about these so-called “bomb trains” in Wisconsin. Now, there’s a new concern, in a neighborhood in Milwaukee.

When the mile-long oil trains lumber by Milwaukee’s Fifth Ward lofts, the cars come roller-coaster close to a renovated building. A sliver of light between brick and steel.

Fifth Ward railroad

From his fifth floor window, Brian Chiu has a front row seat.

“It’s so loud,” Chiu said.

But it’s not the noise that concerns him. The fear is five floors down.

Fracking technology has opened an oil spigot in North Dakota.

“It’s increased the amount of traffic on the railroads exponentially,” Wisconsin Railroad Commissioner Jeff Plale said.

The railroad traffic has increased by several thousand percent.

Bakken crude oil has a very high vapor pressure, meaning it can easily explode. And the tank cars carrying it?

“(They) were not designed to haul crude. A lot of them were designed to haul corn syrup,” Plale said.

When these trains have derailed, the cracker-thin tank cars have ruptured, with disastrous results. By far the worst incident occurred in Lac Megantic, Quebec. Forty-seven people were killed in the fireball.

Quebec train derailment

Three times this year, trains carrying crude have derailed in the United States. Last week in North Dakota, the sky turned gray with smoke.

In March, a train derailed across the border in Galena, Illinois. The wreckage burned for four days.

A week before that, a train derailed in West Virginia. Hundreds had to evacuate.

The train that derailed in North Dakota was headed toward Wisconsin. Two trains before that had just been here.

“We’re kind of at the epicenter of where this stuff is coming,” Plale said.

That brings us back to Brian Chiu and his Fifth Ward home — and those oil trains just feet from the Fifth Ward lofts, going over the S. 1st Street bridge.

FOX6 first photographed the concern in February — but it wasn’t until the snow and ice melted that we saw the full extent. “I beams” that support the bridge have rusted away at the base to wafer-thin strips of steel. In some spots, entire sections are just gone.

Chris Raebel, an engineer at Milwaukee School of Engineering (MSOE) agreed to take a look at what the FOX6 Investigators found.

“My focus is on steel design — just like the bridge,” Raebel said.

Unlike most railroad bridges, which have elevated foundations, the piers on this century-old span reach right to the road — where every winter, salt eats away at the steel.

“That’s hit the base of the bridge and that`s corroding the metal,” Raebel said.

hicks6

In the past, some of the rusted piers supporting the bridge have been reinforced, but several columns have been corroded right through.

“At some point this needs to be fixed. This is not acceptable,” Raebel said.

FOX6 News received similar comments from other structural and civil engineers who saw the photos, but they didn’t want to be identified because they may do business with the railroads. They said things like:

“The level of rust and deterioration is a serious structural problem. They should be contacted immediately.”

And: “I would definitely report these conditions to the owner of this bridge without further delay.”

Canadian Pacific Railroad should already be aware. Canadian Pacific owns the bridge and is required to inspect it each year. In a written reply to a FOX6 request for those records, the company said it “meets or exceeds all federal requirements,” and that the bridge was last inspected in the winter. Canadian Pacific wouldn’t tell us exactly when that was — and whether there was snow on the ground. Canadian Pacific refused to show FOX6 News any of the inspection reports.

FOX6 asked them again earlier this months at a Common Council meeting in Milwaukee.

“We`ve given you a statement on that and we won`t have anything to add,” a Canadian Pacific representative said.

Canadian Pacific had been invited to Milwaukee to answer questions about the oil trains. Canadian Pacific’s brash brush off didn’t sit well with some Common Council members.

“You don`t give that image to the community that your facilities are safe. You don`t give us that confidence,” Milwaukee Alderman Terry Witkowski said.

Ken Wood knows what these inspections entail.

“I’m a structural engineer. My main focus is bridges. I`ve been working with bridges for 20 years — bridge design, bridge inspection, bridge rehabilitation,” Wood said. “You`re going to be looking for fatigue cracks, and the other thing you`d look for is corrosion, certainly, on a bridge — because corrosion is basically taking away the cross section.”

hicks8

If you look at the base of the “I beams” on the bridge in the Fifth Ward, you’ll see layers and layers of flaking — in some places, more than an inch thick. That doesn’t happen quickly.

“It`s been some time, that`s for sure,” Wood said. “What happens during corrosion is the steel expands, sometimes seven to eight times what it is, so you can see that actually happening in the base here,” Wood said.

FOX6’s Brad Hicks: “How do you even inspect this with that much flaking on there without removing the flaking?”

“They would have to remove flaking to see what`s underneath and take some measurements with calipers to find out how much area they perceive is left,” Raebel said.

So that’s what the FOX6 Investigators did.

The beam is nine-tenths of an inch thick, but at the base, only four-tenths of an inch is left. The column is just over an inch thick. Corrosion has eaten it down to less than half that.

FOX6’s Brad Hicks: “The kind of thinning we`re seeing here, does that impact the load capacity of a bridge like this?”

“Yes,” Raebel said. “They have a certain amount of steel they need to resist the load from above.”

And that load is greater than ever.

Engines alone weigh three times what they did when the bridge was built in 1914. And a one-mile train weighs more than 25 million pounds.

“Now a two-mile long train is relatively common,” Plale said.

And with trains like that moving over the bridge daily — metal fatigue adds up.

“Is the bridge really built, with all that rust and all that corrosion, to support that kind of weight?” Chiu wonders.

Officials in the state of Wisconsin had the same question. In 2006, a study was commissioned on the impact heavier trains have on state-owned railroad bridges. That study concluded “many within the railroad industry are concerned that the aging bridge infrastructure will no longer be able to withstand the increased loadings.”

One bridge engineer who examined FOX6’s pictures said the problem may not be that bad, because in theory, you could cut a vertical pier in two horizontally, and it would still hold up the bridge. But that’s assuming you still have inch-thick “I beams” — not corroded columns.

The concern here isn’t that the bridge will completely collapse — but that if a column gives way and the load shifts and the train tips — with the Fifth Ward lofts just feet away, could Milwaukee become another Quebec?

“I would encourage the owner of the bridge to seriously look at this and consider repairs. And it seems like it should be done soon,” Raebel said.

To their credit, the railroads, including Canadian Pacific, have been at the forefront — pushing the federal government for stricter tank car standards. The railroads don’t actually own the tank cars — the oil companies and third-party leasers do.

Eleven days ago, the federal government announced new cars need to be thicker, and the old ones need to be retrofitted within five years.

The federal government is the only entity that can demand the railroad turn over its inspection reports on the bridge. For two months, FOX6 News repeatedly asked the Federal Railroad Administration if it has any of Canadian Pacific’s inspection audits for the S. 1st Street bridge. The agency hasn’t responded.

Local municipalities like Milwaukee are pretty powerless when it comes to regulating the railroads.

On Tuesday, May 12th, the Milwaukee Common Council approved a resolution urging federal regulators to immediately inspect all tracks, bridges and crossings on which Bakken crude oil is carried — but at the end of the day, that’s simply a request.

New rules on oil trains draw flak from firefighters, too

New rules on oil trains draw flak from firefighters, too

WASHINGTON — Lawmakers and environmental and industry groups criticized the federal government’s new safety measures for oil trains when they were announced earlier this month. Now another group has expressed disappointment in the new rules:

Emergency responders. They’re among the first in danger when a fiery derailment happens.

After another oil train derailed and caught fire last week, this time in North Dakota and the fifth in North America this year, firefighters renewed their call for more training and information about hazardous rail shipments.

The International Association of Fire Fighters’ primary objection to the new rules is about their information-sharing requirements. But Elizabeth Harman, an assistant to the general president of the group, also said firefighters needed more training on responding to hazardous materials incidents. The rule didn’t directly address that issue, though some lawmakers have sought additional funding.

“The training that’s needed has been developed,” she said. “This is the first step that needs to be funded and expanded for all first responders.”

Harman said her group had been talking to the Federal Emergency Management Agency about making more competitive grants available for first-responder training.

Tank cars still showing accident vulnerability

Tens of thousands of rail tank cars haul flammable liquids, such as crude oil and ethanol, across North America, and most have weak spots that make them vulnerable to puncture and fire in an accident. A new tank car design has been approved, but is not widely available yet. There have been five serious oil train derailments so far this year.

Since 2010, an exponentially larger volume of flammable liquids, especially crude oil and ethanol, has been moving by rail, and with it has come an increase in risk to communities.

“We need to be prepared for it, and we’re willing to be prepared for it,” Harman said.

The rail industry and the government have funded new training for emergency responders as a result of the increased risk. Railroads train 20,000 firefighters a year in communities across the country, according to the Association of American Railroads, an industry group.

Since last summer, the rail industry has paid to send hundreds more to an advanced firefighting academy in Pueblo, Colo., designed for responding to oil train fires.

While firefighter groups have praised the industry’s efforts, 65 percent of fire departments involved in responding to hazardous materials incidents still have no formal training in that area, according to a 2010 survey by the National Fire Protection Association.

While no first responders have been injured in multiple oil train derailments and fires in the past year and a half, they’ve faced numerous challenges:

– When an oil train derailed and caught fire near Casselton, N.D., on Dec. 30, 2013, a BNSF student engineer became an ad-hoc first responder. According to interview transcripts published last month by the National Transportation Safety Board, the student donned firefighting gear and equipment as he uncoupled cars that were still on the track to move them away from the fire.

– When an oil train derailed and caught fire in downtown Lynchburg, Va., on April 30, 2014, first responders didn’t know right away which railroad to call, since two companies operate tracks through the city. According to a presentation at a conference of transportation professionals in Washington in January, it also took 45 minutes for first responders to obtain documents showing them what the train was carrying.

– After an oil train derailed and caught fire near Galena, Ill., on March 5 this year, volunteer firefighters could reach the remote site only via a bike path. Once there, they attempted to extinguish the fire, but had to retreat when they realized they couldn’t, leaving their equipment behind. According to local news reports, their radios didn’t work, either.

Harman said the U.S. Department of Transportation’s new regulations for trains carrying crude oil, ethanol and other flammable liquids didn’t go far enough with respect to information that railroads provided to communities.

Under an emergency order the department issued last May, railroads were required to report large shipments of Bakken crude oil to state emergency-response commissions, which then disseminated that information to local fire departments.

But under the department’s new rules, starting next year, railroads will no longer report the information to the states, and fire departments that want the information will have to go directly to the railroads. It also will be shielded from public disclosure.

“These new rules fall short of requiring rail operators to provide the information fire departments need to respond effectively when the call arrives,” said Harold Schaitberger, general president of the firefighters group.

Susan Lagana, a spokeswoman for the Department of Transportation, said Friday that the department was reviewing feedback from emergency responders and lawmakers to address their concerns.

She said the new rule would expand the amount of information available to first responders and noted that for now, last year’s emergency order remains in place.

Ed Greenberg, a spokesman for the Association of American Railroads, said the industry was reviewing the new regulations. He said it had shared information with first responders for years and would continue to do so.

Greenberg said the industry was developing a mobile application called AskRail that would give emergency responders immediate access to information about a train’s cargo.

“Freight railroads have ongoing dialogue with first responders, residents and local civic officials on rail operations and emergency planning,” he said.

Emergency planners in Washington state sought more information about oil trains from BNSF, including routing information, worst-case derailment scenarios, response planning and insurance coverage. On April 30, the railroad met with state fire chiefs in Olympia.

“I think both sides learned a little bit about the other group’s point of view,” said Wayne Senter, the executive director of the Washington Fire Chiefs. “I was pretty positive by the end of the meeting the information we asked for in our letter was either available or will soon be available either directly or indirectly.”

Oil in North Dakota derailment was “Conditioned” but not “Stabilized”

Repost rom ABC News
[Editor:  Note that the oil was CONDITIONED according to North Dakota regulations, but it was not STABILIZED which is a stricter standard currently used elsewhere.  (See The difference between oil “conditioning” and oil “stabilization”.)  The vapor pressure of oil on this train was measured at 10.8 psi. Compare this with DeSmogBlog: “…regular crude oil has a Reid Vapor Pressure (RVP) of 5-7 psi and Bakken crude has an RVP between 8-16 psi. To put that in perspective, gasoline typically has a RVP of 9 psi.”  Note also: “The North Dakota train was traveling 24 miles an hour…much slower than the 50 mph limit imposed by federal regulators.”  – RS]

Oil in North Dakota Derailment Was Treated to Cut Volatility

By Matthew Brown and Blake Nicholson, Associated Press, May 7, 2015, 7:09 PM ET

BISMARCK, N.D. — A shipment of oil involved in an explosive train derailment in North Dakota had been treated to reduce its volatility — a move that state officials suggested could have reduced the severity of the accident but won’t prevent others from occurring.

Hess Corporation spokesman John Roper said the oil complied with a state order requiring propane, butane and other volatile gases to be stripped out of crude before it’s transported. That conditioning process lowers the vapor pressure of the oil, reducing the chances of an explosive ignition during a crash.

Despite the treatment of the crude in Wednesday’s accident, six cars carrying a combined 180,000 gallons of oil caught fire in the derailment 2 miles from the town of small Heimdal in central North Dakota. The town was evacuated but no one was hurt.

Investigators on Thursday recovered wheel fragments from the scene. Those will be sent to a government laboratory for analysis, said National Transportation Safety Board spokesman Keith Holloway. A defective tank car wheel is suspected to have played a role in another oil train accident, in Galena, Illinois, on March 10.

The North Dakota train was traveling 24 miles an hour, Holloway said, much slower than the 50 mph limit imposed by federal regulators.

The state volatility standard went into effect last month. It came in response to a string of fiery oil train accidents, including a 2013 derailment in Lac-Megantic, Quebec that killed 47 people and a derailment and fire near Casselton, North Dakota last year.

Members of Congress have called for a stricter, national volatility standard for crude moved by rail.

Roper said the Hess shipment was “fully in compliant with North Dakota’s crude conditioning order.” It was tested immediately prior to loading onto a BNSF Railway train in Tioga and had a vapor pressure of 10.8 pounds per square inch — compared to the 13.7 pounds per square inch maximum under the state standard.

Reducing the explosiveness of crude moved by rail was not supposed to be a cure-all. Federal regulators last week announced a new rule that calls for stronger tank cars better able to withstand a derailment and more advanced braking systems to help keep fuel-carrying cars on the tracks.

“Our oil conditioning order in no way will prevent an accident,” said Alison Ritter with the North Dakota Industrial Commission, which set the vapor pressure standard. “Oil is still going to burn. That’s why the oil was produced. But it’s not as explosive.”

The first witness on the scene Wednesday, 68-year-old Heimdal resident Curt Benson, said he heard and felt an explosion in his house and then witnessed three or four more explosions when he got to the scene. He said it was nowhere near the magnitude of the Casselton explosions, which he saw on television footage.

“I would say that ours was somewhat minor compared to theirs,” Benson said.

Casselton Fire Chief Tim McLean said the disaster outside of that city appeared much worse than the Heimdal incident, but there were other factors to consider than just the volatility of the oil. The Casselton derailment involved more than twice the amount of crude and different kinds of tanker cars, he said. Another freight train, carrying soybeans, also was involved in Casselton and provided more fuel for the fire.

Democrats in Congress contend more needs to be done to reduce the danger of oil shipments by rail that pass through more than 400 counties including major metropolitan areas such as Seattle, Chicago and Philadelphia. Most of that oil comes from the Bakken region of North Dakota, Montana and Canada.

“Why do we let trains with this volatility pass through every day? Why are we letting these guys get away with that?” U.S. Sen. Maria Cantwell, a Washington state Democrat, said in an interview last week after federal regulators unveiled the braking and tank car rule.

BNSF vice president Mike Trevino did not immediately know how much of the oil in Heimdal burned, how much spilled and how much was left in the cars after the fire was extinguished.

The railway was working to remove the derailed cars and repair the track Thursday. It planned to re-open the line Friday afternoon, Trevino said.

The line runs next to an intermittent waterway known as the Big Slough, which drains into the James River about 15 miles downstream. Oil got into the slough, but it was contained and was being recovered, state Emergency Services spokeswoman Cecily Fong said early Thursday.

The tank cars that burst into flames were a model slated to be phased out or retrofitted by 2020 under a federal rule announced last week. It’s the fifth fiery accident since February involving that type of tank car, and industry critics called for them to be taken off the tracks immediately to prevent further fires.

For residents of Heimdal and surrounding Wells County, which oil trains cross daily, the disaster was the realization of something they always feared might happen, County Commission Chairman Mark Schmitz said.

“It’s definitely been in the back of everybody’s minds,” he said.
