Enbridge raises "attack" concerns in Line 9 pipeline filing

|About: Enbridge Inc. (ENB)|By:, SA News Editor

In a sign of the mounting tensions over new energy infrastructure, Enbridge (ENB +0.5%) is raising the possibility of an "attack" on one of its pipelines in an emergency response plan filed with Canada's National Energy Board tied to its Line 9 reversal and expansion.

The specter of an attack comes as efforts to expand markets for Alberta’s oil sands production face intense resistance from environmentalists and First Nations; groups have vowed to set up blockades to stymie ENB’s Northern Gateway pipeline through British Columbia.

Line 9 is designed to move crude from western Canada and North Dakota to Quebec refineries.
