Sacramento leaders: Risk of oil train explosions needs to be acknowledged

Sacramento area leaders say the city of Benicia is failing to acknowledge the risks of explosions and fires that could happen if the Bay Area city approves Valero’s plan to run crude oil trains through Northern California to its refinery.

The accusation, in a draft letter released Tuesday by the Sacramento Area Council of Governments, comes in response to a Benicia report that said twice-daily rail shipments of 70,000 barrels of crude will pose no significant threat to cities on the rail line, such as Roseville, Sacramento and Davis.

The Sacramento group is calling that finding “fundamentally flawed,” and points out that the federal government issued an emergency order in May saying new volatile crude oil shipments are an “imminent hazard” along rail lines.

“I don’t know how you can conclude there is not a significant hazard,” said Kirk Trost, an attorney for SACOG, a planning agency of the region’s six counties and 22 cities. “The (environmental report) never looks at the risk of fire and explosion in one of these situations.”

Trost said the letter has not yet been endorsed by the SACOG, but was written by SACOG staff in consultation with regional leaders.

It urges Benicia to redo its analysis and provide a clearer picture of the risks the project imposes on up-rail cities. It also says the project, proposed by Valero Refining Co., should not be approved without new funding to train firefighters to deal with oil spills and for rail safety improvements.

It also calls for limits on the amount of time crude oil tank cars are stopped or stored in cities. “Our view is they should not be stored in any of our communities along the line,” Trost said.

Valero, which receives most oil at its Benicia refinery via ship, plans to begin taking deliveries by train from various sites in North America, including potentially from the Bakken fields of North Dakota. Bakken trains have been involved in several recent explosive fires, including a derailment in the Canadian town of Lac-Megantic that killed 47 residents. Federal officials said last month that studies show Bakken oil is more volatile than other crude oils. The oil industry disputes that assertion.

The Benicia report concluded that an oil spill between Roseville and Benicia can be expected to happen once every 111 years. It acknowledges “if a release in an urban area were to ignite and/or explode, depending on the specific circumstances, the release could result in property damage and/or injury and/or loss of life,” but doesn’t expand on that statement. Instead, it says rail transport is becoming safer.

The SACOG letter challenges the once-in-111-years figure, noting it was calculated using data from 2005 to 2009, and disregards a dramatic surge in crude oil rail spills and fires in the last two years. Benicia city planners did not respond to a Bee request for comment.

Benicia’s analysis stops at Roseville. Several local officials, including Plumas County supervisor Kevin Goss, say they want it to include likely routes to the north and east, including the Feather River Canyon and the Dunsmuir areas, both of which have been designated by the state as high-hazard areas for train derailments.

“I think it should be studied all the way out to where (the shipments) originate,” Goss said.

Benicia officials have said they did not study beyond Roseville because they do not know which route crude oil trains might take beyond that point.

Several attorneys, unassociated with the case, say state environmental law lays out what cities should study, but has gray areas.

Environmental law attorney Andrea Matarazzo, a partner with the Pioneer Law Group in Sacramento, says case law makes it clear that a city can’t draw a line around its project and study only local impacts. But she said the city can make a judgment call on where to stop, if it has a reasonable explanation.

Another environmental law attorney, Jim Moose, partner at Remy, Moose, Manley in Sacramento, said that CEQA does not require a city to look at the “Armageddon” or worst-case scenario, but cities are obligated to look at reasonably foreseeable impacts. “It seems to me a good EIR would lay out the consequences and not just say the probability of it, especially since the time frame in question is not all that long” from a legal perspective. “But it is a gray area of the law.”

SACOG attorney Trost said the draft letter will be reviewed by the SACOG board later this month. Benicia has set a Sept. 15 deadline for receiving comments and questions to its environmental analysis. Yolo County sent Benicia a similar complaint letter last month.

Oil industry study: Don’t worry, be happy…

Oil industry group study says Bakken, other light crude oils similar

By: Kathleen J. Bryan, August 5, 2014

BISMARCK – A final report on Bakken crude released Monday by the North Dakota Petroleum Council will be presented to the North Dakota Industrial Commission on Wednesday.

The study was done in response to two train derailments last year in which railcars carrying Bakken crude ended in violent explosions. One derailment and explosion in Quebec killed 47 people. Another explosion occurred just outside Casselton, N.D.

The final report confirms preliminary results of the Bakken Crude Characteristics Study, which found that Bakken crude is similar to other North American light, sweet crudes and does not pose a greater risk to transport by rail than other crudes and transportation fuels, the NDPC said in a statement.

“This study provides the most thorough and comprehensive analysis of crude oil quality from a tight oil production basin to date,” John Auers, executive vice president of Turner, Mason & Co., the engineering firm commissioned to conduct the study, said in a news release.

In addition to confirming the initial findings presented in May, the final report also detailed best practices for field operations to ensure consistent operation of treating equipment, Bakken crude oil quality and testing procedures and shipping classification.

In addition to recommended best practices and analysis of the final results from sampling and testing, the final report also compares analysis from other studies on Bakken crude, including a study commissioned by the American Fuel & Petrochemical Manufacturers and the federal Transportation Pipeline and Hazardous Materials Safety Administration.

“The test results from this study are consistent with scientific data reported by the AFPM and PHMSA,” Petroleum Council Vice President Kari Cutting said. “All of this data does not support the speculation that Bakken crude is more volatile or flammable than other light, sweet crudes.”

Soil Contamination in Lac-Mégantic: new study

Contamination in Lac-Mégantic may be less than original estimate: study

By Michelle Lalonde, THE GAZETTE – July 31, 2014

Estimates of soil contamination at Lac-Mégantic after last summer’s deadly train derailment may have been exaggerated, according to a new study commissioned by the provincial environment department.

Envisol Canada Inc., a Montreal-based engineering firm that specializes in geostatistical studies of contaminated sites, re-examined data collected in Lac-Mégantic in 2013. The firm used 3D mapping to visualize contamination dispersion to re-estimate contaminated soil volumes.

An earlier estimate of contaminated soil in the worst-hit area of downtown Lac-Mégantic — using the traditional method, known as the Thyssen Polygons method — was 126,300 cubic metres. The geostatistical method found between 64,000 and 92,000 cubic metres of contaminated soil in the same area.

“With this method we can look at the migration of contamination in specific topology and geology,” said Sara Godoy, a contaminated site consultant with Envisol who worked on the study.

She explained that the geostatistical method, which is used widely by mining companies to analyze the commercial viability of sites and has been evolving since the 1950s, is more scientific and considers more variables than the Polygons method.

It is more expensive because of the equipment and expertise required, but she said it can save money in the long run by pinpointing contaminated areas with more accuracy and avoiding unnecessary decontamination work.

An estimated 6 million litres of crude oil spilled out of the runaway freight train that rolled into downtown Lac-Mégantic on July 6 and burst into flames. The fire killed 47 people, destroyed the downtown area of the tourist town and caused extensive environmental damage to soil and waterways.

Two other reports released last year by the Environment Department indicated a total of 558,000 tonnes of contaminated soil will have to be removed and replaced in downtown Lac-Mégantic.

By the end of October, 75,000 cubic metres of soil had been excavated from the town and moved to a storage and treatment site. The Environment Department has said soil decontamination work could cost between $75 million and $100 million.

The Envisol study recommends the Environment Department conduct further research into whether the province should be using the geostatistical method to characterize soil contamination in the event of significant oil spills in the future.

Old tank cars put Chicago at risk

America’s drilling boom means more freight trains are snaking through Chicago carrying oil, which can erupt into fireballs if the tank cars derail. A new federal proposal to make the cars safer should be enacted as quickly as possible, and any changes in the final rules should enhance safety, not weaken it.

On July 23, U.S. Transportation Secretary Anthony Foxx proposed phasing out tens of thousands of tank cars called DOT-111s that date back to the 1960s and that too easily rupture or get punctured in derailments. In the past six years, oil has spilled in 10 major derailments, many of them fiery. In the worst, 47 people died last year in Quebec. In April, 30,000 gallons of crude oil leaked into the James River amid a blazing derailment near downtown Lynchburg, Va.

Because more than 40 oil-carrying trains pass through metropolitan Chicago every week, the safety proposal is critical. Mayor Rahm Emanuel called it a “very important step to reduce the risk of catastrophic disasters in our cities.”

The weaknesses of older tank cars, which include about 78,000 of the 92,000 now in use, have been known for 25 years. But now there’s a new reason to worry about them. A boom in American oil production, largely due to hydraulic fracturing — or fracking — that extracts petroleum from places where oil pipelines don’t go, has led to a surge in oil-carrying freights. Nationwide, the number of oil carloads jumped from 9,500 in 2008 to 434,000 last year. Trains carrying crude often are longer than 100 tank cars and can carry more than a million gallons.

In May, the U.S. Department of Transportation issued an emergency order requiring railroads to notify local officials before trains carrying large quantities of crude pass through. Now, the department has proposed a range of additional safety options, including requiring new or retrofitted tank cars to have thicker shells, more effective brakes and roll-over protections. Tank cars that don’t meet the new standards would be phased out after two years if they carry the most flammable fuels, including ethanol and most grades of crude oil.

Foxx also is calling for speed limits on trains transporting the fuels, especially through highly populated areas, and testing of the liquids they carry.

The proposals will go through negotiations, including a public comment period, before the final rules come out. Not everyone will agree: Industry representatives, for example, think the proposed speed limits are too low and environmentalists think they are too high.

Fortunately, industry players, including the Association of American Railroads and the American Petroleum Institute, agree tank cars need to be safer. They have offered their own safety enhancements, which don’t go as far as those proposed by Foxx. For example, they want a three-year phase-out period instead of two and would select a design used on tank cars built since 2011 as the new, safer standard.

The final rules should take into account legitimate concerns of business and environmentalists, but the government shouldn’t significantly water down the safety proposals nor let negotiations drag on, putting off the day crude shipments get safer.

We don’t want to see any disastrous fireballs along the many rail lines running through Chicago and its suburbs.
