A dire warning from a broken pipe
The Rainbow spill is just the latest in a series of oil leaks in North America’s vast pipeline network over the past year, and comes as Canadian energy giants are pressing to win approval for some of their most ambitious projects to date. Those include TransCanada Corp.’s Keystone XL pipeline to ship oil sands crude to the Gulf of Mexico, and Enbridge Inc.’s Northern Gateway pipeline to take Alberta crude to the British Columbia coast for shipment to then to Asia, a plan that faces fierce opposition from first nations.
