1) Is there a procedure or policy that describes what actions would be taken, and when?

2) If a storm of exceptional magnitude were predicted to move into the watershed of Jocassee and Keowee reservoirs, what actions would be taken by Duke? Here also, is there a procedure or policy that describes what actions would be taken, and when?
