A marine consultant involved in B.C. oil-spill issues for a quarter century says the risks of a tanker oil spill associated with Enbridge Northern Gateway are simply too great for the project to proceed.
Gerald Graham of Victoria-based Worldocean Consulting Ltd. said that calculations based on Enbridge?s own research show there is a 8.7-to-14.1-per-cent chance of at least one tanker spill greater than 31,500 barrels over a 50-year period, depending on whether the pipeline has a 525,000 or 850,000 barrel per day capacity.
?The consequences of a major oil spill along B.C.?s north coast ? could be catastrophic and irreversible,? he says in a submission to the Joint Review Panel studying the Enbridge proposal. ?Couple this potentially disastrous outcome with a one-in-seven chance of one or more major spills occurring, and the overall threat level posed by Northern Gateway becomes unacceptably high.?
Graham said two events led him into the oil-spill business: the 250,000-barrel Exxon Valdez supertanker spill in Alaska on March 24, 1989, and the Nestucca accident of Dec. 23, 1988, in which 5,500 barrels bunker C oil leaked from a barge off Grays Harbor, Wash., drifted north into B.C. waters.
He also served as ?full-time, in-house consultant? to a federal oil-spill review panel, whose 1990 report recommended, in part, double-hulled tankers and that cleanup volunteers be paid for their services and be covered by then-Workers? Compensation Board regulations.
B.C.?s ?sinuous? and isolated coastline, lack of infrastructure and powerful storms, ?all mitigate against effective oil spill response operations, especially during winter months when the days are short,? and would pose overwhelming challenges to oil-spill responders, Graham said.
At risk are coastal First Nations communities, shellfish harvesting areas, commercial fishing, ecotourism, marine life ? especially diving birds ? and protected areas, including potentially Gwaii Haanas National Park and National Marine Conservation Area reserves.
Graham said a ban on crude-oil tankers ?has been scrupulously observed? in the Queen Charlotte Basin since 1972 consistent with a moratorium on B.C. offshore oil and gas exploration, a wise decision in light of the 2010 Deepwater Horizon disaster in the Gulf of Mexico.
While Transport Canada says Northern Gateway tankers can safely access a terminal in Kitimat, Graham said the marine component of the project ?is not in fact safe? and ?as a whole is not in the public interest.?
Graham noted it is the carrier of the oil ? the tanker owner, not Enbridge ? who would be responsible for oil-spill cleanup operations and associated costs, with Coast Guard assuming a monitoring role, initially at least.
He added Enbridge has not adequately explained how it would clean up after a bitumen spill, or how much would likely be recovered.
?It is clearly in the long-term public interest of all of Canada to save this relatively pristine environment, the largest area of intact coastal temperate rainforest in the world, from the ravages of unchecked industrial development.? he said.
Todd Nogier, a communications manager with Enbridge, argued in response that more than 1,500 tankers carrying petroleum products have safely used the port at Kitimat from 1982 to 2009.
Northern Gateway is committed to a comprehensive marine safety program, he added, including use of only modern double-hulled tankers, independent B.C. pilots and International Maritime Organization certified tanker crews.
The company also commits to vetting tankers through a third-party agency before gaining entry to port, to escort tugs and tethered tugs, and to a radar system to augment the automatic identification system being installed along coastal routes, he said.
Enbridge is also ?committed to developing an emergency response capacity that exceeds Canadian requirements,? he added.
