UPDATE (7:55 p.m.) - Fire chief Gerry Rempel said there is no word on the cause of today's fire. He said no burning has been taking place in the area. Crews will set up sprinklers and a bulldozer will turn the area over to ensure the fire is fully extinguished.
The wind has calmed considerably and there is just one helicopter continuing to work the fire. Fire crews are still spraying water from trucks.
Fire broke out in large waste piles near the Interfor sawmill on Tuesday, April 30 near Castlegar causing a considerable amount of smoke.
Crews from Castlegar, Robson and the mill were assisted by two helicopters with buckets.
The fire may smoulder for several hours given the fuel it's burning in and the fact that it is windy.
As of press time, there were no injuries reported or structures involved.
