Document Description
To avoid any disruption in the operation of the Robert B. Diemer Treatment Plant in the event of an unplanned electrical service interruption by Southern California Edison, Metropolitan intends to install two back-up emergency generators. The first generator will provide emergency power to operate the stationary service water pumps, which provide treated water used for critical maintenance operations at the plant; the second generator will provide emergency power to operate the equipment in the chlorine building to provide disinfection of finished water. Metropolitan intends to use a 121 KW trailer mounted generator for the service water pumps and a 132 KW (65kVA) engine for the chlorine building. Both of these generators will be permitted by the South Coast Air Quality Management District as stationary emergency generators. The permits will allow a maximum of 50 hours for maintenance and testing and a maximum of 200 total hours of operations (including maintenance and test hours) per calendar year.
