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. Rerouting bomb trains away from such specially designated regions would avert a disaster-waiting-to-happen to prime assets along their rail lines.”   The San Francisco Estuary Partnership is one of 28 Estuaries of National Significance.  (I am trying to confirm that the Sacramento-San Joaquin Delta is a National Heritage Area – their website is out of date.)  How might these agencies be brought into the discussion on Valero Crude By Rail?    – RS] 

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.

Diane Bailey: Valero’s Promise to Benicia: We’ll only have an environmental disaster once every 111 years

Valero’s Promise to Benicia: We’ll only have an environmental disaster once every 111 years.

Diane Bailey

Actually, that’s kind of worrisome, especially considering that if you don’t experience that disaster yourself, your kids probably will.  This is one of the many absurd elements showing Valero’s cavalier attitude toward public safety in the draft Environmental Impact Report (EIR) for its proposed crude by rail project, for which public comments were due this week.  The hazard analysis in this report is also a serious underestimate, according to the State among many others: The California Public Utilities Commission notes the serious failure of Valero to address the “potential for tragic consequences of crude oil tank car ruptures” from its proposed Crude by Rail Project.

Valero’s Promise to Benicia: We’ll only have an environmental disaster once every 111 years

This dangerous crude project is so riddled with problems that many communities up-rail are now voicing serious concern.  The City of Sacramento highlights the high concentration of people around the rail freight lines (“more than 147,000 City residents live within ½ mile”) serving the “Valero Benicia refinery [which] is one of two California refineries that are in the process of securing permits to build rail terminals to import Canadian tar sands and Bakken crude oils.” (emphasis added)  And the City of Davis suggests that the “highest levels of protection [be implemented] before disasters such as hazardous material releases and explosions occur [so that] we can avoid having such disasters in the first place.”

Benicians for a Safe and Healthy Community explain why the project is fatally flawed with 132 pages of concerns.  Valero’s crude by rail proposal is like so many other projects popping up all over the nation in a mad rush to access cheaper, extreme and dangerous crude oils, with little regard for public health or safety.  This project is a total disaster (based on NRDC, CBE and other comments) because it brings:

  • More Refinery Pollution: Bringing in extreme crudes like tar sands and fracked Bakken crude will only increase refinery pollution.  Valero’s Benicia refinery already releases 70 percent more toxic chemicals than the average for California.
  • Toxic Plumes Along Rail Lines: This thing called “crude shrinkage” happens during transport, where entrained gases escape, leading to a 0.5 to 3 percent loss of crude oil.  It’s a big problem for volatile crude oils like Bakken, and coupled with the high benzene levels found in some North American crudes (up to 7%), it creates a serious toxic plume around rail lines.  For instance, we estimate over 100 pounds per day of excess benzene emissions from the Valero proposal in the Bay Area (or 1800 times more than the draft EIR reports).
  • Extreme Crudes are Dangerous: Valero and other oil companies pretend that they can mix extreme crudes like tar sands and fracked Bakken into the ideal “Alaskan North Slope look-alike” crude, which sounds great, except that it doesn’t work that way in reality.  Both Bakken and tar sands carry their dangerous properties into any crude oil blend making it more volatile, toxic, and corrosive.
  • CBR Terminals at Refineries Amplify the Hazard: Valero proposes to site its crude by rail unloading facility within 150 feet of a number of very large refinery tanks that store highly flammable and potentially explosive material.  If a derailment occurred at the terminal, it could set off a chain reaction of fire and explosions at the refinery.  And there have been three derailments in Benicia outside the Valero refinery in the past year; luckily those trains were carrying petroleum coke, not crude oil.
  • Risk of Catastrophic Accidents All Along the Rail Route:  Valero’s “Barkan report” that estimates a release only every 111 years from the proposed 100 daily tank cars carrying crude is absurd for many reasons.  Most egregious is that it fails to consider recent data, like the six major crude oil train accidents over the past year that have resulted in massive fireballs and destruction, including 47 casualties in Lac Mégantic. The safety risks to tens of thousands of people living around these freight rail lines remains grave.

The oil industry has been promoting “look-alike” crudes that attempt to mimic conventional crude by blending extreme bottom of the barrel crudes.  The mile-long trains laden with these extreme crudes are a Trojan horse that puts millions of Californians at risk and threatens to undo several decades of environmental progress.  We need a moratorium on all new crude by rail projects, including Valero-Benicia, until the state can assess the cumulative impacts of these projects, make sure environmental impacts are fully mitigated and assure communities that they will be safe.

U.S. Mayors: oil trains must be drained of explosive gas

U.S. oil trains must be drained of explosive gas, mayors say

By Patrick Rucker. WASHINGTON, Sep 16, 2014

(Reuters) – Dangerous gas should be removed from oil train shipments to prevent a future disaster on the tracks, U.S. mayors and safety officials will tell regulators in comments on a sweeping federal safety plan.

The Department of Transportation in July proposed measures meant to end a string of fiery accidents as more trains carrying oil from North Dakota wind across the United States.

Tank cars carrying flammable cargoes would be toughened and forced to move at slower speeds under the plan. But critics say the failure to address vapor pressure, a measure of how much volatile gas is contained in the crude, is a major omission, and intend to drive their point home.

“That’s an oversight we’re going to push them to fix,” Elizabeth Harman, an official with the International Association of Fire Fighters, told Reuters.

Responses to the DOT’s plan are due by Sept. 30, and so far more than 100 comments have been received. Typically in a contentious rulemaking major stakeholders submit their views just before the deadline.

U.S. officials have studied vapor pressure since July 2013, when a runaway oil train derailed in the Quebec village of Lac-Megantic, killing 47 people in a fireball that shocked many with its explosive power.

Until recently, official findings on vapor pressure were in line with industry-funded studies: That the North Dakota fuel is similar to other U.S. light crude oil deemed safe to move in standard tank cars.

But the DOT said last week that it did not properly handle prior samples and that a precision device, a floating piston cylinder, is needed to reliably detect vapor pressure dangers.

Given that disclaimer, many officials simply want dangerous gas removed from crude oil before it is loaded onto rail cars.

“The technology exists so it boils down to costs,” said Mike Webb, a spokesman for Davis, California, who expects nearby cities will join a call for safer handling of Bakken crude from North Dakota.

Under one scenario, energy companies would siphon gas from crude oil and send the fuel to market via different channels. But building such infrastructure, like separators or processing towers, could cost billions of dollars.

The North Dakota Petroleum Council has sampled some Bakken fuel using a floating piston cylinder and the results have been inconclusive, said Kari Cutting, vice president for the trade group.

“But nothing we’ve seen supports the idea that Bakken crude is more volatile than other light crude oils or other flammable liquids,” said Cutting.

But leaders of many railside towns say uncertainty demands the fuel only move under the most stringent safety measures.

“There is a way to haul dangerous cargo safely and that means using state-of-the-art tools,” said Karen Darch, mayor of the Chicago suburb of Barrington, where fuel-laden freight trains cross commuter tracks as many as 20 times a day.

North Dakota officials will next week hold a hearing to consider measures to de-gasify crude oil in the state.

Big debate in North Dakota: stabilize the oil before shipping?

 Does ND crude need to be stabilized?

DICKINSON, N.D. – What can be done to keep trains from becoming “Bakken bombs?”

It’s a question on the minds of many North Dakota residents and leaders, so much that some are calling on the state Industrial Commission to require oil companies to use technology to reduce the crude’s volatility. The words are less than kind.

“Every public official in America who doesn’t want their citizens incinerated will be invited to Bismarck to chew on the commissioners of the NDIC for failing to regulate the industry they regulate,” Ron Schalow of Fargo wrote in a Facebook message.

A train carrying Bakken crude derailed and exploded July 6, 2013, in Lac-Megantic, Quebec, killing 47 people. Another oil train crashed into a derailed soybean train on Dec. 30 near Casselton, N.D. No one was killed.

Schalow has started a campaign to require oil companies that drill in North Dakota to use stabilizers, a technology used in Texas to take natural gas liquids off crude to make it safer to ship. His online petition demands the Industrial Commission to force oil companies to remove all explosive natural gas liquids from crude before shipping it by rail. More than 340 people have signed the petition as of Saturday.

Schalow declined an interview, referring instead to his petition and Facebook page titled “The Bomb Train Buck Stops With North Dakota.”

Throughout North Dakota, residents have called on the state’s government to prevent future disasters like these, but some leaders say implementing stabilizers could cause more problems.

“Now you have to pipe from every one of these wells or you have to find a way to get it to this centralized location to be refined,” state Agricultural Commissioner Doug Goehring said. “That creates huge problems in itself.”

There is a difference between conditioning and stabilization, said Lynn Helms, the state’s Department of Mineral Resources director.

Oil conditioning is typically done at well sites in North Dakota, he said. The gases are first removed from crude. Then the water and hydrocarbons are removed with a heater treater. The crude oil is then put into a storage tank below atmospheric pressure, which reduces the volatility. Those gases can then be flared or transported to a gas processing plant.

“If crude oil is properly conditioned at the wellsite, it is stable and safe for transportation,” Helms said.

Oil that hasn’t been properly conditioned at the wellsite can be stabilized, Helms said, but that would include an industrial system of pipelines and processing plants.

Valerus, a company based in Houston, manufactures stabilizers for oil companies across the country, including in Texas, West Virginia and Canada. It’s a technology Texas has used at the wellhead for drilling the Eagle Ford shale since the early 2000s, said Bill Bowers, vice president of production equipment at Valerus. Recently, a centralized system with pipelines has been developed to transport the natural gas liquid safely.

“Most of that stabilization takes place at a centralized facility now,” he said. “There could be 100 wells flowing into one facility.”

The Railroad Commission of Texas has one rule that Helms has found regarding stabilization, he said. Rule 3.36 of the Texas Oil and Gas Division states operators shall provide safeguards to protect the general public from the harmful effects of hydrogen sulfide. This can include stabilizing liquid hydrocarbons

.Helms added he could not find any other rule requiring companies to use stabilizers, but the rule had an impact indirectly, Bowers said.

“I think what was happening is these trucking companies, either for regulation or just safety purposes, would not transport the crude if it was not stabilized,” Bowers said.

The process is relatively simple, he added.

“All we are really talking about is heating the crude, getting some of the more volatile compounds to evaporate and leaving the crude less volatile,” Bowers said.

The Industrial Commission has asked for public input on 10 items that could be used to condition oil. Though stabilization is not directly listed, it could be discussed under “other field operation methods to effectively reduce the light hydrocarbons in crude.”

The commission will hear testimony on Tuesday, Sept. 23, at the Department of Mineral Resources’ office in Bismarck. Written comment may be submitted before 5 p.m. Monday, Sept. 22.

New rules in North Dakota would regulate conditioning at well sites.

The hearing was brought on by a study from the North Dakota Petroleum Council and discussions held with U.S. Secretary of Transportation Anthony Foxx and Secretary of Energy Ernest Moniz regarding transportation issues.

Installing equipment at the wellhead for conditioning oil takes several weeks, Helms said. Stabilization, on the other hand, could take more than a year to install equipment – if not longer.

Helms said he couldn’t comment on the economic process.

“I do know that a large-scale industrial process would have a big imprint,” Helms said. “It would really exasperate our transportation problems because tens of thousands of barrels of oil would have to be trucked or piped to (a processing plant) and from it.”

Since there is a centralized system in Texas, companies can make a profit off the natural gas liquids. In North Dakota, companies would have to stabilize at the wellhead before pipelines are put in place.

“Given their preference, they won’t buy this equipment,” Bowers said. “They really don’t want to do it.”

There is no pipeline infrastructure to transport natural gas liquids from wellsites, meaning it would have to be trucked or shipped by rail. That could be more dangerous than shipping oil without stabilizing it, Goehring and Helms said.

“By themselves, they are more volatile and more dangerous than the crude oil with them in it,” Helms said. “The logical thing to do is to properly condition them at the wellsite.”

The crude could also shrink in volume, along with profits, Bowers said.

“It seems to me that in the Bakken people are quite happy with the arrangement,” he added. “They don’t believe necessarily that stabilization will change the safety picture.”

Schalow has criticized the Industrial Commission for not acting sooner, stating officials have had 10 years to address the issue.

Goehring said he was made aware of the process recently.

“I don’t believe anybody is withholding information or is aware of anything, nothing diabolical,” Goehring said.

Officials agreed that the process needs to be dealt with on multiple levels, including oversight on railroad safety. Public Service Commissioner Julie Fedorchak outlined a proposal on Thursday for a state-run rail safety program. If approved, the Public Service Commission would hire three staff members for the program.

The commission has been working on the proposal since before the Casselton derailment.

“I share (Schalow’s) concern about having a safe method of transportation, and I think everyone does,” Fedorchak said. “How we get there is the challenge and I think there is a number of different steps. I don’t think there is one solution.”

Many trains carrying Bakken crude travel through Fargo, where Schalow and Democratic Sen. Tim Mathern live.

Mathern follows Schalow’s Facebook page and said he did so out of his concern for transporting oil safely.

“My perspective is that we must preserve and protect our quality of life today and in the future,” Mathern said. “We must be careful that we don’t do kind of a wholesale of colonization of our resources in sending them out. … It’s almost like how do we make sure that we don’t have an industrial waste site as a state?

“In many of our larger cities, we have a section of town that is kind of an industrial waste site. Eventually, someone has to clean that up. Eventually, that is a cost to society, and I am concerned that we don’t let that happen to North Dakota.”

Mathern said safely transporting oil is no longer a western North Dakota or even a state issue; it’s a national issue that must be taken seriously because the oil is being transported throughout the country.

“There is enough responsibility to go around for everybody, including policy makers,” he said. “It’s not just one industry; it’s many industries. It includes the public sector. It includes governors and legislators, and people that are supposed to be attentive to citizens, and to be attentive to the future. We all have responsibility in this.

“This has worldwide consequences. This is an oil find that even affects the balance of power, even politically.”

Mathern said he doesn’t know what Schalow’s motivation is, but it isn’t just Schalow raising the questions.

“I don’t think this is a matter of blaming oil.” Mathern said. “This is a matter of being respectful for our citizens and being a good steward of this resource and a good steward of our future.”
