The Alberta Energy Regulator says close to 60,000 litres of crude oil have spilled into muskeg in the province's north.

An incident report by the regulator states that a mechanical failure was reported Thursday at a Canadian Natural Resources Limited pipeline approximately 27 kilometres north of Red Earth Creek.

The report says there are no reports of impact to wildlife and that a cleanup has begun.

Red Earth Creek is over 350 kilometres northwest of Edmonton.

Carrie Rosa, a spokeswoman for the regulator, says officials have been delayed reaching the scene due to poor weather in the last few days.

No one from Canadian Natural Resources could be reached on Saturday for comment.
