Derailments in Calgary, mislabelled oil at Lac-Mégantic: Oil-by-train dangers further exposed

For the second time in three months, a CP Rail train carrying toxic and flammable hydrocarbons has derailed in the city of Calgary.

Wednesday, eight railway wagons carrying a diluting product used in the pipeline shipment of tar sands bitumen derailed in the Inglewood neighbourhood of Calgary. The train was traveling at a slow speed while exiting CP Rail's Alyth yard in the southeast of the city. Brian McAsey, assistant deputy fire chief of Calgary, told the Calgary Herald, "[The product] is extremely flammable and very volatile."

The derailment also ruptured a natural gas line. Apparently, none of the product spilled from the rail wagons.

On June 27, six wagons on a CP Rail train carrying similar product jumped the tracks while crossing the Bow River on the 100-year old Bonnybrook Bridge. Reportedly, the weight of the cars caused the structural support of the bridge to give way.

That accident happened at the height of catastrophic flooding of Calgary and southern Alberta that month. The rushing water of the Bow River, which passes through the center of the city, might have weakened the bridge's structure, but this was never officially determined.

Oil by rail in large volumes is a new phenomenon in Canada and the United States, beginning only some three years ago. It is expanding rapidly and among the many safety concerns it raises are questions about the ability of old and deteriorating rail lines and bridges to handle the exceptional weight of these trains. This may be a common denominator of the two accidents in Calgary.

Weak safety regulations flaunted

 Meanwhile, the Transportation Safety Board (TSB) of Canada has issued a statement on one aspect of its ongoing investigation into the July 6 oil train disaster in Lac-Mégantic, Quebec. The federal agency says the identification and labeling of the oil carried on the fateful train through the town was false.

Investigators were puzzled from the get-go by the extreme volatility of the product on the Montreal, Maine and Atlantic Railway train. It exploded in a giant fireball near midnight on July 6 in the center of the town when most of the 72-wagon train derailed. Forty seven people died and the surrounding ground and waters have been heavily polluted.

It turns out that the oil, which originated in the Bakken oil field in North Dakota and was carried as far as Montreal by CP Rail, is light and highly flammable. It should have been labeled a 'class two' hydrocarbon instead of the 'class three' designation it carried. 'Class two' means more volatile and dangerous.

The change in designation might not have changed the outcome because there are no additional regulations that it triggers. But it might have prompted additional care in securing the train, which was stationed overnight but by all evidence was inadequately braked. It lost its braking and rolled driverless into Lac Mégantic. And regardless, this is another example of the lax rail safety regulations in the U.S. and Canada that the disaster has brought to light. Rail carriers and their customers operate with too little public and regulatory scrutiny.

As reported in the Globe and Mail, the TSB has cited the North Dakota shipper, an affiliate of Miami-based World Fuel Services Corp., and the purchaser of the oil, New Brunswick's Irving Oil conglomerate, for failing to ensure the oil was properly classified and identified, including on the classification notice that must be attached to each wagon. The report does not mention CP Rail's responsibility.

One reader of the Globe, the newspaper that originally broke the story of the MM&A train product's volatility and has been following it closely since, commented online, "I was told during a high level WHMIS [workplace safety] training course that it was a federal offense to misrepresent, falsify or fail to properly identify materials that are manufactured, stored or transported. Who goes to jail here?"

A portion of Irving Oil's crude shipments from North Dakota to its refinery and export terminal in Saint John were switched following the disaster from the MM&A line to the CN Rail main line that connects the city to Montreal via Quebec and New Brunswick. There has been next to no news reporting of this change, including how many trains per day or week are involved and how residents along the CN line are taking it.

Of course, the main concern that the tragedy in Lac Mégantic has highlighted is the crazed and reckless path of unbridled extraction and burning of fossil fuels down which the economic elites of the world is dragging humanity.
