Calgary-based Enbridge, still mopping up oil from two pipeline spills over the past year in the U.S., has admitted that a May spill on the Norman Wells line near Wrigley, Northwest Territories, leaked closer to 1,500 barrels instead of the initially estimated four, Reuters reported.
The first estimate was based on what Enbridge scooped up from the ground, Reuters said, while further investigation revealed that much more had seeped under the surface.
Norman Wells connects with Plains All American Pipeline LP’s Rainbow Pipeline in northern Alberta. The latter line ruptured April 28, spilling 28,000 barrels near the Lubicon Cree community of Little Buffalo and closing down that pipeline as well. The aboriginal community’s school was closed for a few days, and the cleanup is still ongoing.
In July 2010 an Enbridge pipeline spilled more than 20,000 barrels into Michigan’s Kalamazoo River system, and in September another pipeline leaked in Illinois. First Nations groups have been fighting Enbridge’s attempts to build the Keystone Pipeline, set to travel through aboriginal lands and down through the United States, partly because of the company’s track record.
