Imperial contains produced water release at Cold Lake operation

(UPDATED April 27, 2017) Crews have contained and are focused on recovering approximately 900 cubic metres of treated produced water released from a storage lagoon at Imperial's Cold Lake in-situ operation in northeast Alberta. 
This treated produced water is a byproduct of the bitumen recovery process. This water is pumped back to surface with the bitumen and is treated and reused in operations. 
Recovery efforts are ongoing. A series of berms have been constructed in the area of the release for containment, and tanks and vacuum trucks are being used to store and transport the treated produced water for reuse in the operation. After the treated produced water was discovered, operations identified the source of the release and the release was stopped. Emergency response plans were activated. 
The Alberta Energy Regulator was notified immediately, and has visited the incident site. Communities in the area, including First Nations and Metis, were notified of the incident.
Wildlife deterrents, including noise cannons and monitors, are being used at the site to keep animals and birds away until recovery efforts are complete. There are no reports of affected wildlife and the release does not pose any risk to human health.
