Alarms went off when a power outage resulted in a gas leak at Teck Trail Operations Monday morning, yet levels remained in the safe zone.
Just before 10 a.m. Trail operations lost power due to a problem with the local transmission system, setting off plant alarms and evacuating non-essential personnel from the plant.
According to a press release, power was restored within minutes, however SO2 emissions increased briefly but remained within the permit levels for community SO2 concentrations.
Teck is working with Fortis BC to determine the cause of the power outage.
