Enbridge Inc. estimates that 230,000 litres of oil have spilled from its Athabasca pipeline in Alberta.
The Calgary-based company's latest leak struck on Monday (June 18) at a pumping station southeast of Elk Point.
Alberta's Energy Resources Conservation Board said today (June 19) that it had not confirmed Enbridge's estimate of the size of the "release".
"The pipeline has been shut in and the pumping station has been isolated," the ERCB said in a statement. "No waterways are impacted and cleanup is underway. There were no injuries or no evacuations as a result of the release. All appropriate agencies have been notified."
Enbridge is the company proposing to build the controversial Northern Gateway pipelines from near Edmonton to Kitimat. With a length of 1,177 kilometres, the twin pipelines would transport oil and condensate between the Alberta tar sands and the B.C. coast, where the oil would be loaded on to supertankers.
The Enbridge leak follows two recent incidents in Alberta—a June 7 spill by Plains Midstream Canada in the Red Deer River and a May 19 spill at a Pace Oil and Gas injection well.
"Communities throughout BC and now all the way to Montreal can expect similar spills if Enbridge, backed by a Prime Minister bent on gutting Canada's environmental laws, has its way," Greenpeace climate and energy campaigner Mike Hudema said in a statement today.
