Shell Exploration's plan for exploratory oil and gas drilling in the Beaufort Sea won conditional approval from the federal Bureau of Ocean Energy Management, Regulation and Enforcement. One of the big questions now is what happens if there's an oil spill.
Agency officials are expected as early as next week to act on Shell's oil spill response plan, which conservationists say falls short of the mark for responding to an accident in icy waters, often shrouded in darkness, hundreds of miles from the nearest deep-water port.
Earlier this month, Canada looked at the same issue: How hard would it be to clean up an oil spill in the Beaufort Sea, which straddles the border between the two countries. The answer? Really hard.
Even in the "summer" season between July and October, when Arctic drilling normally occurs, true open water without ice occurs only 54% to 88% of the time, even close to shore, according to the report, prepared for the National Energy Board by S.L. Ross Environmental Research Ltd. of Ottawa.
Conditions can be so bad that no ice cleanup measures are even possible about 20% of the time in June, 40% of the time in August and 65% of the time in October, said the report, which measured typical temperatures, wave heights and ice patterns and how they might prevent the use of such responses as in-situ burning, containment and application of dispersants.
After October, any active response would almost certainly deferred until the following melt season, the report said.
