The owner of an Alberta mine where waste spilled into the Athabasca River says it will still be involved with the cleanup, despite the sale of the facility

Sherritt International says it will continue to work with Colorado-based Westmoreland Coal on the Obed Mountain Mine
remediation plan, and meet financial obligations resulting from the spill. 

Sherritt International announced earlier this week it is selling its entire coal business in Canada to two separate buyers for $946 million. 

An earth berm broke at the Obed Mountain mine near Hinton in October, allowing an estimated 670 million litres of coal waste to spill into two creeks that feed the Athabasca River.
