WASHINGTON—A little-publicized Canadian court decision has thrown a monkey wrench into an on-again, off-again proposal to transport oil from tar sands mines in Alberta to a U.S. seaport in Maine for export.
Last month, judges with the Court of Quebec rejected a Montreal-based oil pipeline company's request to construct a pumping station near the Quebec-Vermont border. The court case pitted environmentalists and Quebec citizens against the owners of a South Portland, Maine-to-Montreal, Quebec oil pipeline.
Halting the pumping station is part of an overarching strategy by environmentalists to challenge Canada's expansion of tar sands oil extraction. They fear the station is the linchpin in opening an eastern gateway for the flow of a dirtier grade of oil from western Canada to Maine. From there, it would likely be shipped to refineries along the Gulf Coast.
The pumping station is a crucial piece of Montreal Pipe Line Ltd.'s plan to reverse the flow direction of its pipeline. Currently, that pipeline carries conventional crude oil from a tanker facility in South Portland to refineries in Montreal. It traverses 236 miles through Maine, New Hampshire, Vermont and Quebec.
From Montreal, the offshore oil is now funneled onto Enbridge Inc.'s Pipeline 9, which travels west all the way to Sarnia, Ontario.
Montreal Pipe Line's request to reverse the flow on the South Portland-Montreal pipeline has had environmentalists on edge for several years because it came in tandem with the Trailbreaker project that Enbridge Inc. first floated in 2008.
That proposal by Enbridge—a separate oil transport company based in Calgary, Alberta—entailed switching the flow on 524-mile Pipeline 9 from westerly to easterly. The 30-inch diameter pipeline currently has the capacity to move 240,000 barrels daily.
Montreal Pipe Line and Enbridge have not talked publicly about collaborating to pump tar sands oil to Maine's Atlantic Coast—but environmental organizations connected the dots long ago.
Enbridge blamed market conditions when it officially shelved its Trailbreaker proposal in 2009. But green groups say the company backpedaled on Trailbreaker when challengers put the reversal idea under a microscope. Conservationists suspect the company is now trying to accomplish the same goal in piecemeal fashion.
As evidence, they point to Enbridge's 2011 application with Canada's National Energy Board to reverse the flow on Pipeline 9 between Sarnia and Westover, Ontario. Westover is roughly halfway between Sarnia and Montreal.
Steven Guilbeault is deputy director of Equiterre, the Montreal-based environmental advocacy organization that spearheaded the legal challenge of the pumping station.
"Enbridge has been saying that its request for a reversal on phase one has nothing to do with getting tar sands from Alberta to Portland," he told InsideClimate News. "But it's hard for us to believe that."
In an interview, Enbridge spokeswoman Jennifer Varey did not deny that the company might eventually try to reverse the direction of the entire Pipeline 9. But right now Enbridge is focused on phase one, the Sarnia-to-Westover segment, she said. Public hearings on that undertaking are scheduled for May 23 to 25.
Reversal of the Sarnia-to-Westover section is a priority of Imperial Oil Ltd., one of Enbridge's key customers, Varey said. Imperial Oil has explained to Enbridge how an easterly flow would benefit its refinery near Westover and access to the Ontario market. A subsidiary of ExxonMobil, Imperial produces more than 200,000 barrels a day from tar sands mines, and claims proven oil sands reserves of more than 2.4 billion barrels.
Initially, Enbridge expects the reversed segment to carry light crude oil. But it will be capable of transporting a range of western Canadian crude oil from Alberta, Saskatchewan and Manitoba. Capacity would start at 50,000 barrels per day and eventually grow to 200,000 barrels per day.
Stopping the pumping station on the Montreal-to-South Portland segment will be a fleeting victory, environmentalists agree, if Enbridge's Pipeline 9 is transformed into a route for shipping tar sands oil east.
Halting the Pumping Station
In May 2009, the commission in Quebec charged with protecting the province's agricultural land approved Montreal Pipe Line's request to rezone land to accommodate a pumping station in Dunham, Quebec, a community near the Vermont border. Company engineers had determined that station infrastructure would have to be situated at that spot to boost the heavy crude over the Sutton Mountains on its journey from Montreal to South Portland.
The agriculture commission's decision was reversed in 2010 after Equiterre appealed to Quebec's administrative tribunal. Last November, Equiterre continued to challenge the pipeline company's quest for the pumping station as the case advanced to the Court of Quebec.
