OOLOGAH, Oklahoma – Workers at PSO's Northeast Station Units Three and Four were evacuated Tuesday morning after an emissions monitor showed unusual readings.
Stan Whiteford, a spokesman for Public Service Company of Oklahoma, said officials could not determine why the monitor was showing unusual readings, so employees were evacuated out of an "abundance of caution."
Evacuated workers were taken to the other side of the property, to Units One and Two.
Officials determined there was no structural or operational problem at Units Three and Four, the coal and fire side of the plant.
The plant remained open during the evacuation.
Whiteford stressed the stack was never in danger of collapsing. He said officials will be on site Wednesday for a follow-up inspection.
