AER says more spill safeguards needed before Primrose returns to normal
CALGARY – The Alberta Energy Regulator says Canadian Natural Resources Ltd.’s Primrose oilsands project in northeastern Alberta won’t be returning to normal full operations any time soon.
Jim Ellis, who heads up the provincial energy watchdog, says it won’t allow a return to business as usual until all of the risks have been addressed and the right safeguards are in place to prevent bitumen from oozing to the surface.
An emulsion of bitumen and water was found to be leaking from four sites more than a year ago, affecting 20.7 hectares.
The AER says 1.2 million litres of the mixture has been recovered and that the spill has been contained.
The AER has taken a look at a “causation review” completed by Canadian Natural last month, as well as an independent technical review of the company’s findings.
The independent review suggests the way in which Canadian Natural injected steam underground was a “fundamental cause” behind the incidents.
