When a CN train carrying crude oil derailed and caught fire last weekend near Gogama, Ontario, it became the fifth loaded oil train to leave the tracks in North America in the past two months — and it's raising new questions about the volatility of diluted bitumen from Alberta's oilsands.

In the March 7th accident, several cars slid into the Mattagami River and ignited, leading local officials to issue a drinking water warning for the Mattagami First Nation.

The accident comes less than a month after another CN tanker train carrying crude derailed in the same region, about 200 kilometres north of Sudbury, spilling an estimated more than one million litres of diluted bitumen into local waterways. Twenty-nine cars left the tracks, causing an explosion that left fires burning for six days.

Officials are still scrambling to clean up the oil, which has spilled into a nearby creek, pond and section of Kasasway Lake, before spring thaw.

Gogama Village Inn owner Roxanne Veronneau told the Toronto Star, “People here are on pins and needles. The tracks run right through town … I’m sure that there’s going to be a lot of talk afterward that this shouldn’t be in the middle of our town.”

“It’s frightening and nerve-wracking, especially after what happened in Quebec.” 

The recent accident near Gogama is the third CN Rail derailment in Ontario in the last month and the fifth tanker train derailment continent-wide.

CN Rail experienced another tanker train derailment on March 5 near Horneypayne, Ontario. No oil spilled as a result of the derailment.

On February 16, a tanker train carrying fracked shale oil from North Dakota derailed in West Virginia, causing a spectacular explosion and forcing the evacuation of two towns. At least one of the derailed cars fell into the Kanawha River, a source of drinking water for two counties.

On March 6 a BNSF train carrying Bakken crude oil derailed south of Galena, Illinois. Twenty-one cars left the tracks and five cars ignited causing a large fireball and plumes of black smoke. Emergency responders spent three days working to bring that fire under control.

Growing Concern Over Volatility of Diluted Bitumen

The spate of recent tanker train explosions in Canada has raised concerns about the volatility of diluted bitumen, which contains highly flammable light hydrocarbons. Although the explosive qualities of Bakken oil — which was central to the tanker train disaster in Lac-Mégantic that left 47 dead — is well-documented, similar attention has not been paid to diluted bitumen, as DeSmogBlog recently reported.

As Railway Age reports, “before CN’s first Gogama wreck Feb. 14, there was a widespread and comforting belief among railroaders, regulators and, yes, even railroad reporters, that tar sands bitumen was much safer for transport by rail than light or conventional crude oils.”

“We now know, thanks to Gogama 1 and Gogama 2, that neither dilbit nor synbit, the synthetically diluted variant of tar sands oil, are safer than untreated Bakken crude.”

The hazardousness of crude oil blends is determined by its ignitability, which is determined by the blend’s most volatile component, Railway Age reports. Thus for diluted bitumen, the volatility of light hydrocarbons used as diluents is a critical factor in determining how fuel will respond in a tanker car accident.

Oil Change International recently calculated an average of 100,000 to 150,000 barrels of dilbit is loaded onto tanker trains at Alberta terminals each day.

“As it takes on average around nine days for a train to reach its destination, this means that at any given time there are between 18 and 27 trains carrying dilbit through the continent loaded with some 900,000 to 1.4 million barrels of dilbit,” Oil Change International’s Andy Rowell reports.

“Together with the roughly one million barrels per day of light, tight crude oil loaded in the Bakken and elsewhere around the continent the threat is enormous.”

Lessons Learned in Lac-Mégantic Not Enough

After the disaster in Lac-Mégantic, Transport Canada ordered all Class 111 tanker cars be upgraded to new standards. The new CPC-1232 standards required cars to be enhanced with half-head shields, fitting protections and normalized steel.

The enhanced cars were meant to prevent another accident like Lac-Mégantic from occurring.

However, as the Toronto Star reported, the Transportation Safety Board’s investigation into the first derailment near Gogama showed the new CPC-1232 cars “performed similarly to those involved in the Lac-Mégantic accident.”

The cars exploded upon impact even though they were travelling at nearly half the speed of the cars involved in the Lac-Mégantic incident.

“The TSB has warned (Transport Canada) that this standard was not sufficient and that more needed to be done to provide an adequate level of protection,” the board’s investigation update states.

“Preliminary assessment of the CPC-1232-compliant tank cars involved in (the first Gogama derailment) demonstrates the inadequacy of this standard given the tank cars' similar performance to the legacy Class 111 tanks cars involved in the Lac-Mégantic accident.”

Greenpeace climate and energy campaigner Keith Stewart told the Toronto Star he’s worried more deaths will occur before the federal government revisits the tanker standards.

“The safety authorities have been warning that even the newer cars are not safe, and we have to wonder where the federal government is in this,” he said.

The federal agency investigating the Lac-Megantic oil train derailment and explosion that killed forty-seven people released recommendations last week to improve the safety of shipping crude oil by rail. If the recommendations are implemented by the federal government they will serve as a strong step forward in protecting communities living along railway lines. 

“The federal transport minister has a clear choice: protect public safety or secure profits of oil companies,” says Keith Stewart, a climate and energy campaigner with Greenpeace Canada.

One of the country’s most active lobby groups – the Canadian Association of Petroleum Producers (CAPP) – responded to the recommendations earlier this week. CAPP asked the federal government “to ensure their implementation does not interrupt service and respects the competitiveness of transporting our products by rail.” In other words, new regulations should not interfere with business as usual for the oil industry.

“Companies have to pay the price for safety. Their profits cannot come before communities, the environment and general safety,” John Bennett, director of the Sierra Club Canada told DeSmog Canada.

The Transport Safety Board (TSB) made three recommendations to Transport Canada improve safety of oil-by-rail shipments: tougher standards for the susceptible-to-rupturing DOT 111 tank cars, strategic routing of oil trains that considers the environment and communities, and emergency response plans for rail lines transporting large volumes of oil.

Greenpeace and the Sierra Club welcome the recommendations. Both organizations have been pushing for stricter oil by rail transport rules since before disaster struck Lac-Megantic, Quebec on July 6th of last year. Rail company CN also supports the TSB’s recommendations. Rail tank cars are owned either by shipping companies or oil producers. Rail companies on the other hand own the rails, and are liable for derailments.

The recommendations focus on tank cars, not the rails themselves, which is one of the shortcomings of the recommendations. Improvements on both are needed.

Recommendations cannot protect the public if they are not implemented. Bennett is not very optimistic the recommendations will be applied by the federal government. Many TSB recommendations in the past, he says, have “just sat there” and were not adopted, like rail line improvement recommendations made after the Lake Wabamun derailment in Alberta in 2005.

Stewart speculates the federal government will wait to see what the U.S. does, something he thinks is very problematic.

“Lives are at risk. Canada should be taking a leadership role,” Stewart told DeSmog from Toronto.

The TSB and the U.S. National Transport Safety Board announced their safety recommendations for oil-by-rail intentionally at the same time. Transport Canada has ninety days to reply to the TSB’s findings. Upon release of the recommendations in Ottawa on January 23rd, TSB chair Wendy Tadros insisted “change must come and it must come now."

If adopted, applying the recommendations may prove to be difficult. Rerouting oil tank cars away from densely populated or environmentally sensitive areas is difficult due to Canada's limited rail options.

Emergency response plans also require greater communication between shippers in the public, especially regarding large oil shipments. Shippers have been reluctant to do this in the past.

“Canadians need to ask themselves why are we doing this? Transporting oil more – whether by rail or pipeline – is a risk with little to no benefits for communities because it is going for export,” says Bennett, who is based in Ottawa.

“We already have enough infrastructure to meet our own oil consumption needs,” Bennett told DeSmog Canada.

Oil tank car shipments in Canada have dramatically jumped from five hundred carloads in 2009 to 160,000 last year, but Canada’s consumption of oil has declined during the same period. All of the recent pipeline proposals in Canada are destined to export oil out of the country with the exception of the Line 9 pipeline in Ontario and Quebec.

“The federal government would be more than happy for this debate to be rail versus pipeline oil shipments,” says Stewart.

“The debate should really be between dirty energy and clean energy and why we continue to invest billions in infrastructure for the fossil fuel industry when that money should be used to fight climate change and reduce our dependence on oil,” Stewart told DeSmog Canada.

The oilsands boom in Alberta and the Bakken shale oil boom in North Dakota coupled with stiff opposition to new pipeline approvals have been blamed for the massive increase in oil-by-rail transport in North America. In the US, oil tank carloads went from 10,800 in 2009 to 400,000 in 2013.

A Canadian National (CN) tanker train carrying liquefied petroleum gas and crude oil derailed early Saturday in the community of Gainford, Alberta, about 80 km from Edmonton. The derailment caused a massive explosion and started a fire, prompting the evacuation of about 100 people from the community.

CBC News reports that "13 cars — four carrying petroleum crude oil and nine pressurized containers carrying liquefied petroleum gas (LPG) — left the tracks along Highway 16 and Range Road 61" at around 1 am Saturday, according to the Transportation Safety Board.

Parkland County spokesman Carson Mills said that there was a "significant explosion" at the time of the derailment, followed by a "smaller one." No injuries have been reported.

CN spokesman Louis-Antoine Paquin said three of the tanker cars, all containing liquid petroleum gas, were on fire and leaking, reports the Guardian. The community, and all residences within 1.6 km of the derailment, were evacuated in case of another explosion.

"It's still a risky situation so we need to contain as much as possible and keep people far away," said Mills. Parkland County has declared a state of emergency for the area surrounding Gainford. Residents have been told to keep out of the evacuation zone until further notice.

Jim Phelan, Parkland County fire chief, said they were "better off to allow [the fire] to vent and burn," adding that it was "unsafe to start fire-suppression activities," reports the Calgary Herald. Phelan told the news conference that residents saw a "large fireball" at the time of the derailment, and said that the cause of the explosion is "yet to be determined."

CBC reports that "55 Evansburg RCMP officers and emergency personnel are on hand and are working with CN and the Transportation Safety Board of Canada to manage the situation," as well as fire crews from Parkland County and Yellowhead County, and a HAZMAT team from Edmonton.

Alberta Environment spokeswoman Robyn Cochrane said it was too early to assess the damage done by the derailment. "We just won't know the extent, from an environmental point of view, until it's all said and done," Cochrane said. "We'll work with the company on containment and then also remediation."  

Parkland County Mayor Rod Shaigec said that "this could have been worse, given the recent incident in Lac-Mégantic — that certainly does illustrate the threats to residents living along rail tracks. So we're thankful it wasn't of that magnitude."

The July 6 derailment of a Montreal, Maine & Atlantic Company tanker train carrying crude oil in Lac-Megantic, Quebec, caused 47 deaths, with about 5.5 million litres of oil burned or contaminating the environment. The tragic incident has put the increasing transport of crude by rail in North America under close scrutiny.

On October 16, just three days before the Gainford derailment, another CN train carrying fertilizer derailed near Sexsmith, Alberta, causing an evacuation of the town.

Greenpeace has spoken out against the Harper government for putting the needs of the oil industry over the safety of Canadians.

"This kind of disaster will become the new normal unless the federal government takes much more effective measures to improve oil transportation safety," said Greenpeace spokesman Mike Hudema.

"The truth is that the Harper government has become such a cheerleader for the petroleum industry that it is failing in its duty to protect our communities and the environment," said Hudema. "This is the third major derailment in Alberta in the last few months. How many more will it take before Ottawa implements transportation safety regulations that were recommended more than a decade ago?"

Documents obtained by Greenpeace recently revealed that CN and Natural Resources Canada were considering a plan last March to move oil by rail from Alberta to BC for export to overseas markets, in capacities matching that proposed for the Northern Gateway pipeline.

The train that derailed in Gainford was travelling from Edmonton to Vancouver, BC, said CN spokesman Paquin.

Whether the Harper government continues to push for the transport of oil by rail despite the numerous safety concerns and growing number of derailments remains to be seen.

As the death toll of the tragic Lac-Mégantic derailment rises to 28, with another 22 presumed dead, the environmental impact of the crude oil spilled during the disaster is also becoming clearer. Further risk of environmental damage comes from the one million litres of crude oil still trapped in tankers at the blast site, according to the Montreal Gazette.

Aaron Derfel writes for the Gazette, that "cleanup crews must wait to begin the months-long decontamination — which is projected to cost tens of millions of dollars — because a police investigation and a coroner's search for human remains must first be completed."

Derfel reports Ghislain Bolduc, a member of the National Assembly for Mégantic riding, as saying that though the investigation must take top priority, "each day's delay in decontaminating the four-hectare site means that oil will continue seeping into the ground and sewage system, which will almost certainly have to be rebuilt."

CBC News reports that the investigation itself will "take months or more" to ensure "Canadians get the answers they need," according to Transportation Safety Board chair Wendy Tavos.

Bolduc emphasized the urgency of removing the five intact rail cars still in the town centre, each containing 100,000 litres of crude oil. This is in addition to residual oil in the damaged cars, which "altogether probably contain about 500,000 litres."

The Montreal, Maine & Atlantic Railway company gave Environment Quebec an estimate of 6.5 million litres of crude oil burned or spilled from damaged tanker cars in the hours following the derailment, with much of it "[flooding] the basements of more than 50 buildings and houses in the downtown core."

In comparison, the 2013 ExxonMobil pipeline oil spill in Mayflower, Arkansas, spilled an estimated 893,000 litres of crude oil, while the 1989 Exxon Valdez tanker oil spill totalled about 41.6 million litres of crude.

The oil also leaked into the sewer system and burned there, causing "underground explosions [that] cracked sewage pipes and blew manhole covers, with geysers of flames shooting up 10 metres in the air," according to Bolduc.

The oil is not just in the water and the soil either, as "above-ground explosions sprayed oil droplets thousands of feet into the sky, and the wind carried that oily mist as far as eight kilometres from the derailment," with Lac-Mégantic residents reporting oil coating their cars.

The Chaudière River has also been contaminated, with "extensive oil slicks" seen on its surface as far as 80 kilometres away, in the town of St. Georges, northeast of Lac-Mégantic. SIMEC, a private company specializing in removing oil spills, was hired on Tuesday to place booms "designed to contain the oil and to prevent it from polluting shorelines" on the river, 1.5 km from the blast site.

"400,000 litres of oil have been pumped out of the sewers thus far," and "4 million litres of oil-tainted river and lake water, as well as sewage" recovered, Michel Rousseau, deputy Environment Quebec minister, told the Gazette. Rousseau added that the cleanup will "cost a lot of money" because "the quantity of oil is very, very big," and that Montreal, Maine & Atlantic will have to pay for most of the bill.

Derfel writes that "decontaminating thousands of tonnes of oily earth" in Lac-Mégantic will "take months and cost millions of dollars," whether done by excavating and replacing 30,000 truckloads of earth from the town or on-site by "setting up a temporary facility to clean the oily earth and then refill the site." This task would be followed by repairing of the sewer system–removing or replacing damaged and contaminated pipes, and "extensive repairs" to the town's sewage treatment plant, which is "clogged with oil as well." The town's water supply, which comes from reservoirs and wells, escaped damage.

"To repair all this, to rebuild the town centre and return to normal will take years," said Bolduc. Rousseau confirmed that soil decontamination could take months, though he couldn't provide an exact number.

Premier Pauline Marois has pledged $60 million in emergency aid to Lac-Mégantic. Bolduc says that this is "a good start," but warns that "millions more are needed, including from the federal government."
