Supertankers, Earthquakes, and Tsunamis, Oh My: Enbridge Has No Spill-Response Plan for Northern Gateway Pipeline

Earlier this month British Columbians were surprised to hear that Enbridge, the main proponent of the proposed Northern Gateway Pipeline, was unable to explain how the company's world-class spill prevention and clean up practices were either world-class or preventative.

At a public hearing in Prince George, Enbridge failed to instill confidence in the audience, admitting the company had no land-based spill prevention plan at all. During cross-examination the company admitted they will not have a spill-response plan until six months before the proposed pipeline would begin operation.

The company was unable to explain how they would respond to land-based spills from a pipeline designed to cover 1,172 km, crossing more than 770 of British Columbia's pristine watercourses. 
 
BC Environment Minister Terry Lake said “the responses that Enbridge/Northern Gateway representatives are giving our legal counsel are long on promises, but short on solid evidence and action to date,” adding, “the company needs to show British Columbians that they have practical solutions to the environmental risks and concerns that have been raised. So far, they have not done that.”
 
Enbridge will be cross-examined regarding maritime spill prevention in Prince Rupert on November 22, less than one month after the town was on high emergency alert after the second largest earthquake in Canada's history threatened coastal towns with tsunami warnings. The 7.7 magnitude quake put the entire Pacific Northwest on tusnami alert, with late-night sirens prompting regional evacuations from Alaska to Hawaii.
 
The October 27 earthquake is a poignant reminder of the unique maritime challenges posed by British Columbia's untamed west coast, a region of rugged terrain, narrow passages, and rocky shores overlying one of the most temperamental fault lines in the world.
 
The quake struck off the coast of Haida Gwaii (formerly the Queen Charlotte islands) about 17.5 km underwater. 
 
 
Bearing a striking resemblance to Canada's worst earthquake, which hit in 1949, Saturday's seismic event did not come as a surprise to those familiar with the region's subterranean geography. The 8.1 magnitude quake in 1949 caused a 500-km long piece of the Queen Charlotte fault (the Pacific's version of the San Andreas fault) to break. When this historic quake hit the Haida Gwaii cows were knocked from their feet, an oil tank collapsed in Cumshewa Inlet, and residents said standing on the street felt like being on the “heaving deck of a ship at sea.” One geologist described falling during the quake and being unable to get back up. Windows shattered in Prince Rupert. 
 
 
This particular earthquake zone is a hotbed of faultline activity, one of the only places in the world where tectonic plates slide past each other, collide and diverge. Usually fault lines only exhibit only one of these movements. This Pacific region is Canada's most earthquake-prone zone.
 
 
Saturday's quake has given cause to reconsider not only the threats posed by the pipeline Enbridge plans to build from Bruderheim, Alberta to Kitimat, BC, but also the dangers of supertanker traffic along a volatile coastline.
 
“I think we have all been complacent about what happens, or what can potentially happen, with an earthquake,” Haisla Nation Chief Councillor Ellis Ross told the Globe and Mail.
 
“We have to think about that in the context of supertankers carrying crude oil in Douglas Channel or outside Hartley Bay or outside Haida Gwaii. … I think that has to be part of the discussion.”
 
Enbridge spokesman Todd Nogier downplayed the risks earthquakes pose to supertanker traffic, saying tsunami dangers would be mitigated by the Douglas Channel's deep and wide waterways. Enbridge infamously misrepresented the Douglas Channel in a Northern Gateway commercial that removed 1000 km2 of hazardous islands that dominate the proposed supertanker highway.
 
 
Of particular concern to BC residents is the unique danger tar sands' oil poses to marine ecosystems. 
 
Oil from Alberta's tar sands is a heavy, viscous crude called bitumen. In order to transport the thick, tarry oil from Alberta through pipelines, bitumen must be diluted. The resulting mixture of diluted bitumen or 'dilbit' is a corrosive blend of thick oil and benzene, naphtha, hydrogen sulphide and other toxic chemicals.
 
In July 2010, a ruptured Enbridge pipeline spilled 3.3 million litres of dilbit into a tributary of the Kalamazoo River in Michigan. What responders learned there was that dilbit, unlike conventional crude, tends to sink in water after a certain amount of time, making clean-up efforts expensive and difficult - if not impossible
 
The cleanup in Michigan has been the most expensive on-shore spill effort in U.S. history, already exceeding $800 million. The toxic spill, which spread for kilometers through connecting waterways, seeped into the riverbed, meaning remediation efforts have decimated the local ecology. Along large segments of the river, cleanup crews have literally dug up and removed contaminated portions of the riverbed.
 
Estimated cleanup costs for conventional oil run at about $2000 per barrel. Bitumen clean up efforts run a tally of an estimated $29,000 per barrel. 
 
In August, the Department of Fisheries and Oceans (DFO) criticized Enbridge for failing to consider the unique composition of dilbit and the threat the mixture poses to waterways. Dr. Kenneth Lee, head of DFO's Centre for Offshore Oil and Gas Energy Research (COOGER), complained Enbridge's pipeline plan had “strong limitations due to inaccurate inputs.”
 
“The Northern Gateway pipeline proposal lacks key information on the chemical composition of the reference oils used in the hypothetical spill models.”
 
Dr. Lee sought approval to study the “toxic effects of reference oils to marine species” in relation to Enbridge's Northern Gateway Pipeline proposal. According to the Globe and Mail, the DFO would not say whether Dr. Lee's proposal was approved, although Dr. Lee confirmed his research position had recently been threatened by federal government budget cuts. 
 
It remains to be seen how Enbridge will respond to inquires regarding maritime spill prevention and cleanup on November 22.
 
One can only hope they come prepared this time - although preparation isn't their strong suit.

Geoff Morrell, the senior vice president of communications at BP, wants the whole country to know that the company’s negligence that led to the Deepwater Horizon oil geyser has not destroyed the Gulf of Mexico. And all of those fears about lost revenue and declining tourism along the Gulf Coast? That never happened, according to Morrell.
