New Bakken volatility standards are pointless

The explosion risk still exists, which emboldens pipeline supporters — but why must our choices be so dismal?

I’ve seen Bakken crude oil as it comes out of the ground. It was surprising in several ways: It was almost green, quite fluid and downright fizzy with natural gases. It’s the high gas content that makes Bakken shale oil so explosive.

When the state of North Dakota established new limits on vapor pressure last week for the oil shipped out of the state, my first reaction was relief. Flammable liquids with lower vapor pressures are less volatile. We’ve seen several explosive rail accidents in recent years involving Bakken oil; an oil train derailment last year in the small Quebec town of Lac-Mégantic killed 47 people and flattened its downtown. I was pleased that regulators were addressing this problem.

But when I took a closer look at the numbers, I felt more dismay than relief. Even if oil producers exceed the regulators’ demands — and regulators say they often do — Bakken crude will still be explosive.

The appropriate comparison seems to be gasoline.

Lynn Helms, head of the North Dakota Department of Mineral Resources, said the new vapor pressure standard of 13.7 pounds per square inch (psi) would make Bakken crude no more volatile than the gasoline we put in our cars every day.

In March, an investigation by the Transportation Safety Board of Canada concluded that the Bakken oil in rail cars at Lac-Mégantic was “as volatile as gasoline,” but the vapor pressure was measured at 9 to around 9.5 psi. In other words, the Bakken crude that exploded in Lac-Mégantic was less volatile than what North Dakota regulators are demanding now, and it still exploded.

In a New York Times article last week [North Dakota Regulators Tell Producers to Filter Crude Oil of Flammable Liquids], Clifford Krauss reported: “Once the rules are in force early next year, transported North Dakota crude oil will have a similar volatility to that of automobile gasoline, which should decrease the risk and size of any fire that might occur once a rail car is punctured in an accident, according to state regulators.” His story never mentioned the findings of the Canadian government.

Why wasn’t this New York Times reporter more skeptical of the assurances of North Dakota oil regulators, especially after the recent New York Times revelations about the leniency of regulators toward the oil industry?

The new vapor pressure standard announced last week is pointless. We will still face danger from exploding oil trains.

This disturbing fact tends to encourage pipeline supporters. Pipelines are safer, they say. In the past, oil transported by pipelines has tended not to explode and kill people; instead it spills and contaminates streams, lakes and aquifers. If you value people’s lives over clean water supply, in the short term, pipelines seem better.

But why do we have to make such lousy choices to keep our domestic energy boom rolling — to keep workers working and our dream of energy independence alive? Let’s do everything we can to encourage the other domestic energy boom, the wind and solar boom, that has already begun and that survives today despite many obstacles, including national policies that still encourage fossil fuel, yesterday’s energy source. If we were to place a price on carbon tomorrow, we would not need as many pipelines and we would be able to reduce the number of oil trains passing through our neighborhoods.

Climate experts urge us to leave much of the world’s remaining fossil fuel, including Bakken crude, in the ground. If we do as they advise, we will disrupt job markets and be forced to rethink the way we do almost everything. Why should we voluntarily face such disruption? One very good reason: We already face the prospect of pervasive disruption posed by a changing climate. It’s far preferable to take well-designed and systematic measures to control disruption than let disruption control us.

Albany NY Area officials say crude-oil transport is getting safer

Repost from The Press Republican, Plattsburgh, NY
[Editor: the safety improvements showcased here are far from adequate, nevertheless, it’s a good update on conditions in New York.  Sen. Schumer is absolutely right – the DOT-111 tank cars should be taken out of service immediately… and not just in New York.  And Bakken crude should be stabilized before it is transported (not just conditioned) … just as it is in Texas.  – RS]

Area officials say crude-oil transport is getting safer

Lohr McKinstry, December 6, 2014
A DOT-111 oil tank car sits on a siding in the Midwest. New York state is adopting tougher rules on use of the tank cars, which pass through Essex and Clinton counties enroute to Albany,

LEWIS — New state regulations on crude-oil trains should help make them safer, Emergency Services officials from Essex and Clinton counties said recently.

State agencies have implemented 66 actions designed to strengthen standards, regulations and procedures to make the transport of crude oil by rail and water in New York safer and to improve spill preparedness and response.

Gov. Andrew Cuomo received a status report outlining the progress made by multiple state agencies after they were directed to evaluate the state’s capacity to prevent and address crude-oil accidents.

Local leaders have been concerned about the 100-car-plus oil trains moving through Clinton and Essex counties as the crude oil extracted in North Dakota arrives via Canadian Pacific Railway trains.

The oil is on its way to the Port of Albany, where it is stored for transport to various refineries.

IMPROVEMENTS

Essex County Emergency Services Director Donald Jaquish said he sees the new procedures as a safety benefit to the North Country.

“It’s a step in the right direction,” he told the Press-Republican. “We’re in a better position than we were a year ago.”

There’s been concern the trains could derail, and the oil burn or explode, as it has in other regions, and Jaquish praised Canadian Pacific for trying to make the tracks and tank cars safer.

“Upgrading the DOT-111 tank cars, rail replacement and maintenance, and specialized training are all beneficial to safety.

“Canadian Pacific has been helping us with training, hands-on-experience, that first responders need for these situations.”

EVACUATION PRACTICE

The tank cars are not owned by Canadian Pacific but by oil companies and vendors, and as a federal common carrier, the railroad is required to transport them.

Both the railroad and federal regulators have pushed for upgrades to the DOT-111 single-shell cars or a switch to the stronger DOT-109 or 112 cars.

“In almost any situation we get, we will be doing evacuations,” Jaquish said. “We’ve been working with Clinton County on planning and implementation.”

Clinton County Emergency Services Director Eric Day said any improvements to the transport of oil cars are welcome.

“At the end of the day, what they’ve done is good, no question,” Day told the Press-Republican. “Any regulatory move to make the DOT-111 cars safer is a plus. It’s a long time coming.”

One problem is that there are thousands of DOT-111 tank cars still in service, he said.

“There are so many of them (DOT-111 cars) out there on the tracks. They’re not going to stop moving the oil before they fix the cars. The oil is not going to stop coming any time soon.”

STATE GUIDANCE

Day said enhanced state regulations on oil shipments will be helpful.

“If there are changes that are pushed upon them (shippers), it can only make it safer. We’ve seen some of the benefits of the state’s work with regard to planning,” he said.

“We have guidance now on firefighting potential on dealing with these things. There are so many variables. Multiple cars of this crude oil on fire are a different animal.”

He said that, thanks to a donation, they now have the foam needed for such fires. The expensive product costs $30,000 for 1,000 gallons of foam but puts out crude-oil-based fires.

VOLATILE GAS

The North Dakota Industrial Commission has proposed draft regulations to remove the volatile gases from the oil before it is shipped, and Day said that provision is a good one.

“One of the things that makes the Bakken crude so volatile are the gases in the oil. The gas works its way out and is stuck in the head space of the car. If they breech, there’s flammable gas; cars that aren’t breeched and heat up, the gas could expand and be a problem.

“Removing that gas is a possibility before they put in the cars and ship it. If they could do that, it’s a big win.”

FEDERAL ROLE

Cuomo called for the federal government to mandate tank-car upgrades or replacement.

“The federal government plays a vital role in regulating this industry, and Washington must step up in order to expedite the implementation of safer policies and rules for crude-oil transport,” he said in the release.

The governor said the oil-production industry has resisted stronger tank-car standards and regulations requiring companies to reduce the volatility of crude before shipment.

A new report from the Brattle Group for the Railroad Supply Institute, a trade group, showed that a proposed federal rule to upgrade rail-tank cars could cost $60 billion.

According to the report, the high price tag is largely due to the costs associated with potential modifications to tank cars, early retirement of existing tank cars, temporarily using trucks instead of rails for transport and lost service time for tank cars under modification or awaiting modification.

‘TIME BOMBS’

U.S. Sen. Charles E. Schumer (D-NY) has also come out against use of DOT-111 cars.

“These outmoded DOT-111 tank cars … are ticking time bombs that need to be upgraded ASAP,” the senator said in a news release.

“That is why for two years, since the tragedy at Lac-Megantic, I have pushed federal regulators to phase out and retrofit these cars.

“As a result of our efforts, the federal Department of Transportation has put a proposal on the table that could start taking these cars off the tracks within two years, as well as restrict the speeds at which these trains operate.”

On July 6, 2013, a 74-tank-car train carrying Bakken light crude derailed in Lac-Megantic, Quebec, and the tank cars exploded, killing 47 people, destroying 30 buildings and spilling 1.5 million gallons of heavy crude oil.

That disaster was followed by oil-train-explosion derailments in Alabama, North Dakota, Illinois and New Brunswick, Canada.

North Dakota to Require Producers to Treat Crude Before Shipping

Move Comes Amid Growing Safety Concerns About Oil-Laden Trains

North Dakota plans unprecedented steps to ensure crude pumped from the state’s Bakken Shale oil producing region is safe enough to be loaded into railroad tank cars and sent across the country.

In the first major move by regulators to address the role of gaseous, volatile crude in railroad accidents, the North Dakota Industrial Commission, which regulates energy production in the state, said it would require Bakken Shale well operators to strip gases from crudes that show high vapor pressures.

“We believe the vast majority of our Bakken oil will fall well below the standard,” Lynn Helms, director of the state’s Department of Mineral Resources, said at a news conference.

The proposed state rule will require all operators to run crude oil through equipment that heats up the crude and forces out gases from the liquid. An estimated 15% of current producers without such equipment will have to submit quarterly test results showing their wells don’t exceed the state’s proposed 13.7 pounds a square inch vapor pressure limit, Mr. Helms said.

Those changes could make the new rules more costly for the state’s smaller producers. Jack Ekstrom, vice president of government affairs for Whiting Petroleum Corp. said the rules don’t appear to be “a major material cost” he said. “This is perhaps more of a concern to a marginal or smaller operator.”

A representative for the North Dakota Petroleum Council, an industry lobbying group, criticized the proposed rules for “micromanaging the industry,” and said they could lead to unintended consequences such as increased burning of excess natural gas at well sites.

The proposal also would prohibit blending condensate or natural gas liquids back into crude and require rail loading terminals to inform state regulators of any oil received for shipment exceeding the vapor pressure limits, Mr. Helms said.

He said the new rules would cost industry, but not enough to make drilling Bakken oil uncompetitive.

Scott Skokos, an organizer with landowners’ group Dakota Resource Council, called the move by the regulator “a step in the right direction.”

The state’s decision follows months of officials’ playing down the possibility that Bakken crude was more volatile and could explode more readily than other North American crudes.

Several oil trains have derailed and exploded since 2013, spurring concern about the safety of growing numbers of oil-carrying trains delivering oil produced by the shale boom.

‘…a step in the right direction.’

—Scott Skokos, Dakota Resource Council

The Wall Street Journal reported in February that Bakken crude contained several times the amount of combustible gases as oil from elsewhere. Relying on an analysis of data collected at a pipeline in Louisiana, the Journal pointed out that oil from the Bakken Shale had a far higher vapor pressure, making it much more likely to emit combustible gases, than dozens of other crude oils.

The proposed rules specify how wells should treat the oil to ensure it is “in a stable state,” according to Mr. Helms.

Executives from the top oil companies working in the Bakken Shale told state regulators in a September hearing that their crude is safe to transport by train using existing treatment methods, opposing potentially costly requirements that they make the oil less volatile before shipping it.

But studies by the U.S. and Canada have indicated that Bakken crude is more volatile than other grades of oil. Industry-funded studies, including one commissioned by the NDPC, have said Bakken oil is no different than other types of light oil.

The state expects to issue final rules by December 11th.

Production of light shale oil through hydraulic fracturing has soared, accounting for most of the additional three million barrels a day of oil that the U.S. produces today compared with 2009. Much of that is shipped to refineries by railcars, especially crude produced from Bakken Shale due to the area’s few pipelines.

Fed Measures on Crude Oil Fall Short, Put Protected Estuaries and Heritage Areas at Risk

Repost from HuffPost GREEN, The Blog
[Editor: Note reference near the end on federally designated National Heritage Areas and Estuaries of National Significance which “require special protection from potential explosions and spills.

Fed Measures on Crude Oil Fall Short, Put Hudson River at Risk

By Ned Sullivan, President, Scenic Hudson and Paul Gallay, President, Hudson Riverkeeper, 10/21/2014

Last May, we wrote about how the Hudson River Valley has become a virtual pipeline for the transport of highly flammable Bakken crude oil in unsafe DOT-111 railcars–the same tankers whose derailment has caused numerous explosions across the U.S. and the death of 47 people in Lac-Megantic, Canada.

Since then, very little has changed, which means the situation has just gotten worse.

Each day, more than 320 of these oil-laden cars continue to pass through our communities and along the shores of the Hudson River, one of the world’s most biologically diverse tidal estuaries. To date, we’ve escaped disaster, although three trains pulling empty DOT-111s have derailed in the Hudson Valley. Each time a rail accident occurs in the region, as it did just last week, the environmental community holds its breath, expecting the worst.

What will happen if cars full of Bakken crude do go off the tracks? The federal Pipeline and Hazardous Material Safety Administration (PHMSA), quoting the National Transportation Safety Board (NTSB), recently provided the answer: They “can almost always be expected to breach,” making them “vulnerable to fire.” The result would be catastrophic to the public health, vital natural and historic resources, and drinking water supplies of a region stretching from Albany to New York Harbor. It would cause long-lasting, if not permanent, damage to the estuary’s entire ecosystem and the foundation of a vibrant, $4.75-billion tourism economy.

Both Scenic Hudson and Riverkeeper have been advocating vigorously for increased federal protections, including an immediate ban on the use of DOT-111s for transporting crude. Therefore, we were bitterly disappointed and frankly frustrated by new draft regulations proposed by the PHMSA regarding tanker redesign and other measures for reducing the risks of explosions and spills from these “bomb trains.” They just don’t go far enough fast enough, meaning our communities remain at grave risk. It also means the proposed rules don’t comply with federal law, which requires strict safety upgrades that will protect the public.

In formal comments on the regulations our organizations submitted jointly, we outline how the PHMSA’s rules are replete with loopholes and weak safety proposals.

  • Despite acknowledging the safety hazards of DOT-111s, the proposed regulations would very slowly phase out their use for transporting Bakken crude and allow 23,000 of these outdated, dangerous cars to remain on the rails for shipping heavy Canadian tar sands crude, which presents different but equally serious safety and environmental risks.
  • The regulations fail to require full disclosure of rail traffic information to first responders, and instead ask the industry if it would prefer to keep this information confidential.
  • The regulations fail to require the most protective braking improvements or speed restrictions, and fail to even consider limits on the length of trains that could reduce accident risks and impacts of a derailment.
  • The regulations would allow railroads to continue operating 120-car trains of Bakken crude oil without requiring any train-specific spill response plans–despite the fact that a 120-car train carries as much oil as an oil barge or tanker, both of which must have spill response plans approved by the Coast Guard.

Put simply, these rules defer to the rail and oil industries at every turn–and they won’t stop the next bomb train disaster. As the NTSB warned in its official comments on these proposed rules, “Each delay in implementing a new design requirement allows the construction of more insufficiently protected tank cars that will both increase the immediate risks to communities and require costly modification later.” Further, the NTSB concludes that the government’s proposed standards for new and existing tank cars offer options that “do not achieve an acceptable level of safety and protection.”

We deserve real protection for our communities and the environment. And we deserve it now.

For these reasons, Riverkeeper and Scenic Hudson have called on the PHMSA to issue an emergency order requiring immediate adoption of the most stringent tank car standards, speed restrictions and use of electronic controlled pneumatic braking in all trains carrying crude, as well as closing loopholes in the rule that leave heavy tar sands crude and trains carrying fewer than 20 cars of Bakken crude completely unaddressed. (Scenic Hudson also has called for rules requiring Bakken crude to be processed at its source in North Dakota, making it much less volatile for shipment. This is done at many Texas oil fields.)

In addition, we are calling on federal rail regulators to designate the Hudson River Valley, as well as other similarly situated regions, highly important natural and cultural resources under PHMSA routing regulations. This means that the natural and cultural resources within this federally designated National Heritage Area (one of only 49) and Estuary of National Significance (one of 28) require special protection from potential explosions and spills. Rerouting bomb trains away from such specially designated regions would avert a disaster-waiting-to-happen to prime assets along their rail lines. In the Hudson Valley, those assets include six drinking water intakes; 91 state, county and municipal parks; 40 Significant Coastal Fish and Wildlife Areas; nine colleges; 69 public schools and 80 medical facilities.

The federal government has the responsibility to ensure the public’s safety. Until Washington steps up and fulfills this obligation, we’ll have to keep on holding our breath.
