The Energy Resources Conservation Board is investigating after oil spill in northern Alberta Wednesday.

The leak happened at a remote facility northwest of Manning, which is about 225 kilometres north of High Prairie.

The facility is owned by the Calgary-based Keyera Corporation.

 ERCB spokesman Bob Curran says the spill was small and had no impact on people or the environmment.

The company reported it to the ERCB as required.

A Keyera spokesman said the company is still trying to determine exactly how much oil leaked.
