Seattle City Light calls the plant desk and report that a spill of 150,000 cfs has been implemented due to an emergency what immediate action do you take?
If all gates are operational, initiate a full 200 second gate movement on all gates releasing ~ 50,000 cfs. While the gates are raising call PSOSE for precise gate openings, 2 more 200 second raises are likely required but PSOSE can calculate exact openings and keep the gates out of cavitation zones.
In the event of a catastrophe (including Boundary emergency release) that requires immediate evacuation of the SEV facilities the Plant Operator must dial 51333, wait for the ringtone, press "1" for 2 seconds, wait for 3 confirmation tones and then hang up. This will initiate the muster alarm at SEV. If the plant desk does not receive a call from mustered personnel within 3 minutes then repeat the process.
