No injuries were reported following a fire last night at BioPower in Atikokan.
Company officials say it broke out around 7 p.m. in their wood yard near a hydro line.
The flames spread to the forest at the north side of the mill.
The firefighters were eventually able to gain control and snuff out the flames.
The Ministry of Natural Resources and Forestry reports about 20 hectares of forest were scorched by the blaze.
