Why oil trains (don’t have to) explode: Everything you need to know

Oil Train Derailment Illinois

Crude oil was never supposed to explode.

Then a train pulling 72 cars of it derailed in a tiny town in Quebec in July 2013. The oil turned into a mushroom cloud of flame. It looked terrifying. Watch the first minute of this video:

Forty-seven people were killed that night.

Since then, eight more trains hauling oil have derailed and erupted in flames, drawing scrutiny to a new phenomenon: Crude oil, which once primarily moved in ships and pipelines, is being hauled around North America by rail in unprecedented volumes. More than a million barrels a day now move that way.

The federal government, which regulates train safety, has slowly moved to make oil trains more secure. Regulators are focusing on strengthening the tank cars carrying the oil.

But safety experts say regulators have ignored steps that would make oil trains less likely to go off like a bomb when they derail.

Depending on where it is produced, oil can be dark and thick or light and free flowing. Different amounts of highly flammable gases like propane and butane can be dissolved in it, affecting its volatility. (These are what your backyard gas grill uses.)

Much of the oil moving by rail comes from North Dakota. And what’s coming out of the ground there has been unusually volatile. North Dakota crude moving in Oregon contains far higher levels of propane than similar types of oil.

Some North Dakota crude has been more volatile than gasoline. So when the trains have derailed, the flammable gases within have fueled those sky-high fireballs.

That doesn’t have to happen.

Michael Eyer, a retired Oregon hazardous materials train inspector, said federal regulators could impose a cap on the amount of flammable gas allowed in the oil.

“You would have a fire,” Eyer said. “But you would not have the mushroom cloud in the sky.”

Producers can strip out those highly flammable gases before the oil is loaded for shipment. The process is called stabilization. North Dakota oil regulators estimate it would add $2 to the cost of every barrel.

Less volatile oil could still burn in a derailment, Eyer said. But nearby residents and firefighters responding to train accidents would be safer: Those fireballs don’t just shoot up. They spread, too.

State regulators in North Dakota have set the first ever limit to tame the most volatile crude. It went into effect April 1. It requires a less-intense treatment process that North Dakota regulators estimate will cost 10 cents per barrel.

But Eyer and a crude oil expert say the limit is too high to have widespread impact. The oil that exploded in Quebec in 2013, for example, wouldn’t have been affected.

Harry Giles is a retired federal official who used to oversee crude oil quality for the country’s Strategic Petroleum Reserve. He said North Dakota’s limit should be set lower.

“It would increase the safety and lessen the risk,” Giles said. “Fires would be less intense.”

Compare this fire during a May 2011 derailment northwest of Portland near Scappoose. That’s ethanol — pure grain alcohol — burning. It’s far less volatile than North Dakota crude.

The fire was still dangerous. But firefighters were able to get close enough to put water on the cars. That’s a fire hose spraying at the top of the photo.

Now see what happened after a December 2013 derailment with crude oil in North Dakota.

Look close. That’s a train down there at the bottom.

Stricter limits would reduce the dangers faced by millions of people who live next to rail lines nationwide, Eyer said.

That includes Oregonians like Jamie Maygra, a retired ironworker who lives in Deer Island, along the state’s primary oil train route. He said he worries about the oil’s volatility every time he drives near an oil train with his 2- and 3-year-old granddaughters.

He said he’s frustrated that neither industry nor safety regulators have moved faster to keep people like his granddaughters safe.

“I think about that all the time,” Maygra said. “The chances of that happening are slim, but it’s a lot more with this oil. They don’t care about nothing but money. That’s what’s aggravating. They put profit before people.”

Federal safety regulators say they’re studying what makes the oil so flammable and what could be done. Tim Butters is the administrator of the Pipeline and Hazardous Materials Safety Administration, the federal agency with authority to set limits. He recently told a Congressional committee his agency, known as PHMSA, is looking at ways to remove flammable gases from crude.

But the methods for doing that are already well known. They’re currently used in Texas oil fields, where flammable gases are separated and piped to nearby plants.

Eyer said the agency should move faster.

“The industry needs to figure out what the hell this stuff is and regulators need to say ‘We’re going to act now,’ ” he said. “How many rivers on fire and deaths are needed? What is the price?”

If federal regulators forced North Dakota producers to emulate what happens in Texas, those producers would have to burn or ship the gases they stripped from the oil. Currently, though, North Dakota does not have enough pipelines to move those flammable gases nor a market for them.

Susan Lagana, a PHMSA spokeswoman, said her agency is concerned about the volatility of oil moving by rail. But research is needed to determine exactly what makes the explosions so severe, she said, and what could be done to minimize them.

Eyer and Giles agreed that North Dakota’s volatility limits were too high, but they didn’t agree about what the right level is.

“That’s what we need to know,” Lagana said. “We are willing to consider all options to address making the product safer in transportation.”

The relevant research, being done by the federal Energy Department, should be finished this summer, Butters told Congress. But he didn’t promise any next steps once it’s done.

In the meantime, allowing producers to leave those flammable gases in the oil gives them more profit, allowing them to slightly bulk up the volumes they ship. It’s one reason the oil industry is fighting suggestions to stabilize North Dakota oil.

Don’t blame the oil for explosions, the industry argues. Blame the derailing trains.

“Keeping the trains on the tracks is the only way to ensure that crude… will be transported in the safest possible manner,” Charles Drevna, president of American Fuel and Petrochemical Manufacturers recently wrote.

Solely focusing on tank cars and trains “is not enough,” Eyer said. “The starting point is always what are you putting into the car?”

A bill introduced recently in the U.S. Senate by Democratic Sens. Patty Murray, Maria Cantwell, Dianne Feinstein and Tammy Baldwin proposes limiting the volatility of oil moving by rail. They want the rules in place within two years.

It’s a sign that political leaders have realized the North Dakota oil poses unique risks that could be reduced. A spokeswoman for Sen. Ron Wyden, D-Oregon, said he is tracking the issue and continues talking to federal transportation officials to find ways to address it.

Citizens: oil tankers traveling through Guadalupe to the Phillips 66 refinery could explode

Train of thought: Citizens worry oil tankers traveling through Guadalupe to the Phillips 66 refinery could explode

By David Minsky, April 1, 2015

Residents worried that their town could become the scene of an oil tanker explosion voiced their concerns during a March 24 Guadalupe City Council meeting.

The Santa Maria Refinery property sits on the Nipomo Mesa, less than 5 miles away from Guadalupe, and that’s where owner Phillips 66 wants to build a rail spur to connect it to an existing Union Pacific Railroad line. Plans for a transfer station are in the works, too.

The project would change where the refinery gets oil and how the resource is delivered to the refinery, which currently receives most of its oil via pipeline from Northern Santa Barbara County. The rail spur could bring up to five 80-car trains per week carrying crude oil through downtown Guadalupe on the Union Pacific line. Union Pacific Railroad would be responsible for delivering the railcars, refinery spokesperson Jim Anderson said at the meeting.

On the table was whether or not the City Council would endorse a letter from 3rd District Santa Barbara County Supervisor Doreen Farr, who opposes the project. All sides—including representatives from Phillips 66, who encouraged the council to not take action on the letter in light of a yet-to-be completed environmental impact report; and the Mesa Refinery Watch Group, which opposes the project—made their cases before a packed house of politicians, residents, and journalists. The letter was secondary to the discussion, though. The real question that was debated: Is it safe to allow railcars of crude oil to pass through Guadalupe?

Citing more than 60 years of safe rail operations, Anderson said the extension is necessary for the refinery to maintain its present rate of crude oil processing. With Central Coast oil production in decline and a strong demand for fuel—only one of the many products refined from crude—in California, Anderson said the spur is needed.

“The only way to fill up and complete that 44,000-barrel-a-day rate is, rather than propose a marine terminal or a truck terminal with thousands of trucks on the highway, we felt that a rail terminal, which is sitting right next to the mainline railroad tracks, would be the best alternative,” Anderson said, adding that the trains would be similar to the ones that have rolled through Guadalupe in the last 10 years, but would be slightly longer.

At one point while Anderson was speaking, an audible train horn blared in the distance, prompting chuckles among the crowd.

The idea of oil trains wasn’t so funny to Laurance Shinderman, who spoke on behalf of the Mesa Refinery Watch Group, which formed to identify the negative impacts of the rail project. He noted the explosive potential of crude’s flashpoint—the temperature at which vapor forms and can ignite.

“The lower the flashpoint of the crude, the greater the risk,” Shinderman said, emphasizing that oil being shipped has a lower flashpoint. “I’m not a chemistry engineer, but I’ve done enough reading on this.”

He went on to cite several instances of tanker cars exploding or catching on fire, including the 2013 Lac-Megantic rail disaster in Quebec where multiple tankers carrying Bakken formation crude oil derailed and exploded, killing 47 people and destroying more than 30 buildings in a town roughly the size of Guadalupe.

Shinderman described the Phillips 66 proposal as “oil roulette.”

More people spoke against the spur after Shinderman, including Joyce Howerton, an aide who spoke on behalf of state Sen. Hannah-Beth Jackson (D-Santa Barbara). Amy Anderson, a Santa Maria resident and volunteer for the Santa Barbara County Action Network, briefly talked about empty oil tankers.

“An empty liquid petroleum gas tanker is actually even more explosive than a full one,” she said. “Once they start to explode, you can only hope the town’s been evacuated and there are no onlookers because the fragments from the exploding tankers will assault Guadalupe like shrapnel from a roadside bomb. That’s not an exaggeration.”

Neither minimizing nor enhancing the risk of danger, Guadalupe Police Chief Gary Hoving said his biggest concern is a lack of emergency resources to evacuate the city in the event of a tanker explosion. Citing a FEMA estimate, Hoving said a blast zone with shrapnel would be limited to about 1 1/4 miles. He recommended an evacuation zone of at least 7,000 feet.

“A derailment in the city of Guadalupe would necessitate an evacuation of the entire city,” Hoving said during the meeting. “The major concerns that I have are related solely to public safety … our lack of sufficient fire and police, especially for an initial response.”

The last train derailment in Guadalupe was in 2007, when several cars came off the track, including four that spilled cases of Corona beer.

Hoving also asked where the funding for additional resources would come from.

Phillips 66 spokesperson Anderson noted that his company is presently working with the governor’s office to place a fee on each barrel of oil that’s loaded and unloaded. The money collected would go into a state-level emergency services fund and provide money for increasing the capability of emergency response, he said.

The fate of the spur is still up in the air. At the end of the debate that Tuesday night, the city eventually voted 4-1 to not to take any action on endorsing Farr’s letter. Councilmember Ariston Julian dissented. Before the vote, Julian made a motion to endorse the letter, but it wasn’t seconded.

Julian expressed concern for the city’s water source and residents living immediately near the tracks—including the soon-to-be-built Pasadera housing development that broke ground on March 4—if an accident caused oil to spill or explode.

“In the unlikelihood that there is, we have a potential of losing people and also losing our water source,” Julian said.

Pittsburg CA: WesPac oil storage project no longer includes Bakken crude trains

Pittsburg: WesPac oil storage project no longer includes Bakken crude trains

By Sam Richards, 04/01/2015 11:40:04 AM PDT

PITTSBURG — Amid the growing national debate over the safety of transporting crude oil by trains, an energy firm has dropped the rail component from a controversial proposal to transform an old PG&E tank farm into a regional oil storage facility here.

WesPac Midstream LLC’s proposed Pittsburg Terminal Project, which had been attacked by local activists as posing a serious safety threat, is back on the table after a year of dormancy.

But the elimination of the crude-by-rail element doesn’t mean critics are satisfied that a revived oil storage and shipping operation would be safe for the community. The dormant tanks are less than a half-mile from hundreds of houses and apartments on West 10th Street and in the downtown area between Eighth Street and the waterfront.

“There are still environmental issues … having the stored oil in those tanks so close to homes, ground pollution issues, vapors from the big tanks,” said Frank Gordon of Pittsburg, a vocal opponent of the project in the past.

The City Council on Monday is expected to approve another review of the proposed oil storage facility’s environmental impact reports — this time excluding the prospect of rail deliveries.

The WesPac plan, as presented in October 2013, included facilities just north of Parkside Avenue — south of the tank farm — to handle as many as five 104-car oil trainloads a week.

Art Diefenbach, WesPac’s Pittsburg project manager then and now, said this week that the “regulatory environment” surrounding rail shipments of crude oil — in particular, the more volatile Bakken crude from an area covering parts of North Dakota, Montana and Saskatchewan in Canada — isn’t stable enough to plan a major project around.

“We just can’t proceed with that uncertainty floating out there,” said Diefenbach, also noting that falling crude prices help make shipping oil by rail a less attractive alternative, at least in the short term.

He said protests against the crude oil trains — in Pittsburg, the East Bay and the nation — were a factor in the plan change, too. Such decisions, he said, “are always a combination of factors.”

Oil trains, he said, are out of the picture for the foreseeable future.

Several communities in the East Bay have expressed alarm in recent months about the transport of crude by rail through the region in the wake of several high-profile derailments and accidents in North America in recent years, including one in Quebec in 2013 that killed 47 people and destroyed part of a town. At a meeting in Crockett last week, residents raised concerns about plans to ship oil by rail through Contra Costa County and other parts of the Bay Area to a refinery in Central California.

Without trains, all oil arriving at the WesPac facility would be via either ship or a pipeline from the southern reaches of the Central Valley.

Pittsburg Mayor Pete Longmire said removing the trains from the WesPac equation should result in a safer project for the community. “And it’s probably less controversial than before,” he said.

Although the council will decide Monday night on only an amendment to one of the project’s environmental studies, Longmire expects a large crowd to turn out to discuss what many still likely see as a polluting facility that could present a health danger to the hundreds of people who live near the old tanks.

WesPac Energy, as the company was called then, first applied in March 2011 for needed permits to renovate and restart the former PG&E oil storage and transfer facilities off West 10th Street on the city’s northwestern edge. The $200 million project calls for an average of 242,000 barrels of crude or partially refined crude oil to be unloaded daily from ships on the nearby Sacramento River, and from pipelines, and stored in 16 tanks on 125 acres.

The oil would then be moved to Contra Costa County refineries, and the Valero refinery in Benicia, via pipeline for processing.

The Pittsburg Defense Council, a group of opponents to the WesPac project in general, had decried the prospect of Bakken crude oil coming into town for unloading. Some already has rolled through Pittsburg on BNSF rails, destined for a Kinder-Morgan facility in Richmond.

Diefenbach said that, assuming various approvals come at a typical pace, construction could begin in early 2016, and likely would take from 18 to 24 months.

Longmire said he doesn’t have strong feelings about WesPac either way at this point but insists that the project — with its jobs and its boost to the local economy — must be safe. Gordon said he is still leaning against it. They agree, though, the formal permitting process must be allowed to play out.

Said Gordon, “We’ll have to see what they do with the new” environmental impact report.

If you go…

The Pittsburg City Council meets at 7 p.m. Monday at City Hall council chamber, 65 Civic Ave. in Pittsburg. The public is welcome.

New vapor pressure rule in North Dakota fails to account for additional explosion risks

North Dakota’s new oil train safety checks seen missing risks

By Patrick Rucker, Mar 31, 2015 4:14pm EDT

WASHINGTON, March 31 (Reuters) – New regulations to cap vapor pressure of North Dakota crude fail to account for how it behaves in transit, according to industry experts, raising doubts about whether the state’s much-anticipated rules will make oil train shipments safer.

High vapor pressure has been identified as a possible factor in the fireball explosions witnessed after oil train derailments in Illinois and West Virginia in recent weeks.

For over a year, federal officials have warned that crude from North Dakota’s Bakken shale oilfields contains a cocktail of explosive gas – known in the industry as ‘light ends.’

The new rules, which take effect on April 1, aim to contain dangers by spot-checking the vapor pressure of crude before loading and capping it at 13.7 pounds per square inch (psi) – about normal atmospheric conditions.

The plan relies on a widely-used test for measuring pressure at the wellhead, but safety experts say gas levels can climb inside the nearly-full tankers, so the checks are a poor indicator of explosion risks for rail shipments.

It is “well-understood, basic physics” that crude oil will exert more pressure in a full container than in the test conditions North Dakota will use, said Dennis Sutton, executive director of the Crude Oil Quality Association, which studies how to safely handle fossil fuels.

Ametek Inc, a leading manufacturer of testing equipment, has detected vapor pressure climbing from about 9 psi to over 30 psi – more than twice the new limit – while an oil tank is filled to near-capacity.

About 70 percent of the roughly 1.2 million barrels of oil produced in North Dakota every day moves by rail to distant refineries and passes through hundreds of cities and towns along the way.

The state controls matter to those communities because there is no federal standard to curb explosive gases in oil trains.

North Dakota officials point out that the pressure limit is more stringent than the industry-accepted definition of “stable” crude oil. They also say that they lack jurisdiction over tank cars leaving the state and that the pressure tests are just one of the measures to make oil trains safer.

“We’re trying to achieve a set of operating practices that generates a safe, reliable crude oil,” Lynn Helms, director of the North Dakota Department of Mineral Resources, has said. Helms has also said that test readings for near-full containers were less reliable.

However, given different testing and transport conditions, industry officials say the pressure threshold may need to be lowered to reduce the risks.

Limiting vapor pressure to 13.7 psi in transit would require an operator to bring it to “something well below that” at the loading point, Sutton said.

The uncertainty about regulatory reach and safety has spurred calls for the White House to develop national standards to control explosive gas pressure.

“Let me be really clear,” Democratic Senator Maria Cantwell of Washington state told reporters last week. “They should set a standard on volatility.”

The National Transportation Safety Board, an independent safety agency, has already encouraged a federal standard for “setting vapor pressure thresholds” for oil trains citing Canadian findings linking such pressure and the size of explosions in train accidents.

Meanwhile, a leading voice for the oil industry is lobbying Congress to resist federal vapor pressure benchmarks.

Last week, the American Petroleum Institute urged lawmakers to oppose “a national volatility standard” and pointed to an Energy Department study that the severity of an oil train mishap may have more to do with the circumstances of the crash than the volatility of the cargo.

That same report said much more study was needed to understand volatility of crude oil from the Bakken. (For a link to the study: tinyurl.com/nvjqmxt)

The oil industry has said that wringing ‘light ends’ out of Bakken crude may keep a share of valuable fuel from reaching refineries.

Reuters reported early this month that Transportation Secretary Anthony Foxx took his concerns about Bakken oil volatility to the White House last summer and sought advice on what to do about the danger of explosive gases.

The administration decided that rather than assert federal authority it would allow the North Dakota rules to take root, according to sources familiar with the meeting.
