Soil Contamination in Lac-Mégantic: new study

Repost from The Montreal Gazette

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.

Comment period starts for oil train rules

By Timothy Cama – 08/01/14

The Obama administration Friday formally published proposals in the Federal Register to stiffen safety rules for trains carrying crude oil and other fuels, kicking off a two-month period in which the public can comment.

The proposals were prompted chiefly by the increase in oil shipped by rail from the Bakken region of North Dakota, which Transportation Secretary Anthony Foxx said last week necessitates “a new world order on how this stuff moves.” A train carrying crude derailed in Quebec last year, setting off an explosion that killed 47.

The Department of Transportation (DOT) proposed phasing out old rail cars for oil and other flammable liquids like ethanol, implementing new speed and braking standards for the trains and establishing a new testing and classification system for the fuels. Foxx called the rules “the most significant progress” in protecting the country from explosions caused by trains carrying Bakken crude.

DOT said it wants comments on three different possible rules for speed limits and three different options for the thickness of steel on cars.

DOT also said it was not likely to extend the comment period beyond the 60-day standard, “given the urgency of the safety issues addressed in these proposals.”

Ethanol dependent on old-style tank cars

Railway Supply Institute: Ethanol dependent on old-style tank cars

1 Aug 2014

Houston  — The US ethanol industry is particularly vulnerable to pending regulatory changes that will require retrofitting or retiring a type of railcar that carries 98pc of ethanol production.

In comments to the US Department of Transportation’s (DOT) planned changes to tank car design released last week, the Railway Supply Institute (RSI) said about 29,200 of the approximately 29,780 tank cars moving ethanol as of June were doing so in unjacketed old-style DOT-111 tank cars. Those cars must be retrofitted or retired under the proposed rules.

Jackets add another layer of steel to the tank, increasing overall protection. They are an option to retrofit DOT-111s to make them safer.

DOT-111 cars have been under renewed scrutiny since several exploded into flames in a July 2013 derailment at Lac-Megantic, Quebec, killing 47 people. Four more fiery crude-by-rail accidents since then spun regulators in both the US and Canada into action on car design.

But it was an ethanol train derailment in June 2009 that spurred the first wave of action. The Cherry Valley, Illinois, accident killed one person and prompted industry to voluntarily strengthen car design in 2011, creating the current industry standard known as CPC-1232.

But despite the reliance on older DOT-111s to move ethanol, documentation from the Surface Transportation Board and the Pipeline and Hazardous Material Safety Administration shows there was only one ethanol-by-rail accident last year — with no release or fire — compared with five crude-by-rail accidents.

The last reported US ethanol-by-rail accident involving a fire was in August 2012 at Plevna, Montana, when 17 cars derailed and 12 spilled more than 245,000 USG.

According to RSI’s comments to the DOT, which were released last week along with a series of proposals on new speed limits and tank car design for flammable liquids, 580 tank cars either of the newer CPC-1232 model or jacketed DOT-111s were moving ethanol in June, making up 2pc of the fleet.

Meanwhile, of the 42,550 tank cars moving crude in June, 19,750 either were newer-model CPC-1232 or DOT-111 with jacketing, accounting for 46pc.

“Our industry’s rapid expansion occurred in 2005-2006-2007, and the only cars made available were the [DOT-111] cars, which were purchased or leased with the expectation of a 40- or 50-year lifespan,” Bob Dinneen, chief executive of the Renewable Fuels Association, told Argus. “When you started to see a lot more crude oil moving from the Bakken, by then the [CPC-1232] cars were being made available, so they were lucky to get those cars.”

DOT last week suggested that DOT-111 tank cars be retired after two years, to be replaced either by a more stringent design it has proposed, another proposed by the Association of American Railroads that is largely similar except that it lacks electronically controlled pneumatic brakes, or continuation of the current CPC-1232 design.

The initial regulatory push is too broad-brush and should be more focused on crude, Dinneen said.

“They ought to be prioritizing by the commodity about which, by their own admission, they are most concerned,” Dinneen said, referring to light crude. Conversely, the American Petroleum Institute chastised the government for singling out Bakken crude, which it said is no more volatile than other grades.

Yesterday, railcar lessor GATX also called for a more commodity-based approach to the DOT-111 phase-out, saying it is not currently clear what markets DOT-111s might serve once they are banned from crude or ethanol use.

Emergency Management Magazine: States Focus on Rail and Energy Pipeline Safety

States Focus on Rail and Energy Pipeline Safety

Sharp increases in U.S. oil production have caused safety problems transporting the liquid. Now states are trying to fix the problem.
Jeffrey Stinson, Stateline | July 31, 2014

The sharp increase in U.S. oil production and its promise of energy independence is coming with a disastrous byproduct: spills that threaten lives, communities and the environment.

In the past 18 months, about 1.2 million gallons of crude oil produced in the U.S. or Canada has been spilled from train cars and pipelines in at least seven states, sparking explosions, fires, or the evacuation of homes or offices in four instances.

Nobody has to tell the residents of Lynchburg, Virginia about the danger of the millions of gallons of crude oil rolling along rail lines or through pipelines every day. On April 30, more than a dozen train cars filled with crude oil derailed near Lynchburg’s downtown, causing a fire that forced hundreds of people in a 20-block area to evacuate. Nobody was injured, but thousands of gallons of oil spilled into the James River.

In response to the growing problem, the U.S. Department of Transportation last week issued proposed rules calling for upgraded railroad cars, better braking systems and tighter speed controls.

The federal action followed stepped-up efforts by several states to try to prevent spills and respond to disasters:

  • The California legislature last month approved a new 6.5-cent fee on every barrel on crude oil carried by rail and some pipelines through the state. The state will use the money, estimated to bring in $11 million in the first full year, to expand its coastal spill prevention and response program to inland streams, rivers, lakes and wetlands. It’s also beefing up its rail safety inspection program.
  • Minnesota Gov. Mark Dayton, a Democrat, signed legislation in May to implement stricter oversight of railroad companies, require more rail inspections and provide for better emergency response training and preparedness. To pay for it, Minnesota this year will collect $6.4 million in fees from railroads and pipeline companies.
  • New Hampshire Gov. Maggie Hassan, a Democrat, signed legislation earlier this month that authorizes the state to impose stricter preparation and response requirements on pipelines than federal law requires. The state Public Utility Commission also was given authority to inspect interstate pipelines to provide more frequent checks than federal officials give.
  • Oregon Democratic Gov. John Kitzhaber last week released a study of oil moving through his state that calls for more state rail inspectors, more money for training and improved cooperation with railroads. Last month, Washington Gov. Jay Inslee, a Democrat, ordered a similar review of risks, regulations and preparedness in his state. In January, New York Democratic Gov. Andrew Cuomo also issued a similar order and dispatched inspectors to rail yards to look for defects on cars that could cause derailments.

Nearly all the action in the states was prompted by disasters governors and lawmakers saw in other states or across the border in Canada. Their worst fear is what happened in Lac-Megantic, Quebec, where 47 people were killed last July when an unattended 74-car train derailed. The spilled crude caught fire, then several cars exploded and about half the downtown was destroyed.

“I want to know how much oil will be shipped through my state and how we can be assured the kind of tragedy that happened in Quebec won’t devastate families in our communities,” Inslee said last month in ordering the study in Washington.

Matt Swenson, Dayton’s press secretary, said Minnesotans only needed to look at neighboring North Dakota to see what could happen: Last December, a train carrying grain derailed in front of a mile-long train carrying crude oil near Casselton, not far from the Minnesota border. Twenty cars spilled oil, some exploded. Fire forced evacuation of the town, but nobody was injured.

Every day, seven similar oil trains with about 110 cars carrying about 3.3 million gallons of crude travel through Minnesota, the state said. Other states are witnessing similar traffic, and it’s on the rise.

About 264 million gallons of crude oil were shipped by rail through California last year, said Alexia Retallack in the state Fish and Wildlife Department’s Office of Spill Prevention and Response. That’s 46.2 million gallons more than in 2012.

Railroads Pick Up Slack

More crude oil is on the move across states as production in North America booms from the fracking of Bakken oil deposits underlying North Dakota, Montana, and Canada’s Saskatchewan and Manitoba provinces, and from the tar sands of Alberta.

Production in the U.S. alone will be 8.5 million barrels a day this year, the U.S. Energy Information Administration estimates. That’s estimated to grow to 9.3 million barrels daily next year. And there aren’t enough pipelines to get the crude to the nation’s 115 refineries to be turned into gasoline and other products.

Republican North Dakota Gov. Jack Dalrymple said last month that pipeline capacity in his state needs to double to about 1.4 million barrels a day by 2016 to carry all the crude produced there. Currently, the state is producing about 220,000 barrels a day more than pipes can carry.

Railroads are picking up the slack, even though the Congressional Research Service said in a May report that it can cost from $5 to $10 more a barrel than pipeline delivery. The number of carloads of crude oil, each carrying about 30,000 gallons, that ended up inside the U.S. rose to 435,560 last year, the Association of American Railroads says. That’s up from about 30,000 in 2010.

In a recent analysis of data from the federal Pipeline and Hazardous Material Safety Administration, the McClatchy News Service found that 1.15 million gallons of crude oil spilled from rail cars in the U.S. last year. That’s more than in all the years combined since the data was first collected nearly four decades ago.

The worst accident was in November in Aliceville, Alabama, where 748,800 gallons spilled from a 90-car train after 12 cars derailed and three exploded. Nobody was injured.

Although widely considered safer than rail shipment of crude, pipelines do spill. A split in a pipeline in March 2013 dumped as much as 5,000 barrels of Canadian tar sands oil into a neighborhood in Mayflower, Arkansas.

Concern over pipeline spills is what drove New Hampshire state Sen. Jeff Woodburn to sponsor the legislation giving his state greater control over pipelines. The source of worry is that the 236-mile Portland-Montreal Pipeline, built to carry conventional crude oil from Maine, through New Hampshire and Vermont to Canadian refineries, can instead be used to ship to the U.S. tar sands oil, which is heavier and dirtier.

A spill, Woodburn, a Democrat, said, could devastate the fragile environment in his northern area of the state, which attracts tourists.

An analysis of federal spill data by the Manhattan Institute for Policy Research last year found that through 2009, pipelines released more oil per spill than rail.  Even with the recent increase in oil transported by rail, pipelines still carry much more. Furthermore, because pipelines often run through isolated areas, it often takes longer to get to the site of a leak and seal it.

But there’s a difference between pipeline spills and rail car spills, said Carl Weimer, a Whatcom County, Washington, commissioner and executive director of the Pipeline Safety Trust that studies and advocates for greater pipeline safety.

Pipelines may spill more oil when an accident happens, Weimer said, but they usually cause mostly environmental damage because they’re located in out-of-the-way places. Railroads travel through populated areas and their spills can endanger more people and cause greater property damage.

“The real question is: Is either one as safe as they need to be?” Weimer said. “I don’t think they are.”

Lighter and Sweeter

The nature of much of the oil being shipped is heightening states’ concerns. Bakken crude is a lighter, sweeter crude that federal regulators say may be more flammable than other crude – though the American Petroleum Institute that represents the oil and gas industry disputes that.

Bakken crude was involved in the fiery crashes in Virginia, North Dakota, Alabama and in Quebec.

The new proposed federal rules are largely aimed at Bakken crude. Older rail tanker cars will be banned from shipping it across the states within two years unless they’re retrofitted with thicker skins and anti-rollover protection to meet the newest standards.

At present, the freight railroad industry says it uses about 92,000 tank cars to carry flammable liquids, such as crude, and that 18,000 are built to the latest standards.

The Association of American Railroads says the industry already has moved to reduce speeds on oil trains with 20 or more cars carrying crude and include at least one older tank car to no faster than 40 mph in 46 urban areas around the country.

Federal regulators are weighing whether they should go even slower, possibly 40 mph in all areas and 30 mph in urban areas. But the association, which represents major carriers, said going just 30 mph in urban areas could cost it 10 percent of its capacity to ship cargo, and slow down some freight and Amtrak passenger trains traveling across parts of the country.

Railroads also are alerting states when and where trains carrying 1 million gallons or more of Bakken crude will travel in keeping with a May 15 order from the U.S. Department of Transportation. And they’ve said they’ll work with the states and communities on any new spill response efforts just as they have so far.

“We take our responsibility for moving oil in a safe and efficient manner seriously,” the railroad association said. “That is why the rail industry is working with our customers, suppliers and (federal regulators) to find ways to make a safe network even safer.”

That’s what states say they’re doing, too, as they know their citizens need the energy and at a reasonable price.

“We need to move crude oil,” said California’s Retallack. “But we need to do it in a way that doesn’t pose risks to citizens or the environment.”

Or, as Sen. Woodburn of New Hampshire put it: “We want to be accepting to changes and challenges on the energy front – but we want to be in the driver’s seat.”
