The state of Alaska is fining three companies a combined $882,000 for a construction incident at the George M. Sullivan Plant in Anchorage.
The state’s decision was due to violent shaking and high pressures in the plant’s steam piping system soon after a contractor removed a pressure release valve, Alaska Public Media reported.
Though Municipal Light & Power called for the system to be shut down during the Sept. 2016 incident, operators working for Universal Energy delayed taking action. Municipal Light & Power then evacuated their employees, and the pressure relief valve wasn’t reinstalled for nearly a week.
Universal Energy was hit with a $182,000 fine, while two other companies, Price Gregory International and Quanta Power Generation, now have a combined $700,000 fine.
Municipal Light & Power was not fined due to the evacuation order.
The project installed a 120-MW, combined-cycle GE LM6000 turbine in the facility, replacing six older thermal units.
