1 POWER GENERATION SYSTEMS The Power Generation Systems on HI 595 CF&D consist of three Waukesha 7042 gas driven generators and two diesel driven generators. Two of the three Gas Generators must run to provide power for the entire facility. The two Diesel Generators provide limited power for essential equipment but cannot run the entire facility.

7 E. WAUKESHA 7042 GAS DRIVEN GENERATORS PRE-STARTUP PROCEDURES SECTION 3, PART A before beginning any start-up procedures. NOTICE: Any of the three Gas Driven Waukesha 7042 Generators can be used but a minimum of TWO Generators are required to be on line to provide full facility power 1. Check engine fluids on the Waukesha 7042 gas engines a. Verify coolant level is adequate b. Verify lube oil is adequate 2. Verify all vent and drain valves in fuel gas supply components are closed a. MAJ-2110, Generator Fuel Filters b. MAJ-2120, Generator Fuel Filters c. MAJ-2130, Generator Fuel Filters NOTICE: Any vessel purging should be done prior to getting system ready for start-up. 3. Verify manual valves are open or closed as necessary to correctly direct fuel gas to the Generator Prime Movers 4. Verify that the liquid level controllers, pressure controllers and control valves are in service and ready for flow a. MAJ-2110, Generator Fuel Filter Inlet gas PCV b. MAJ-2120, Generator Fuel Filter Inlet gas PCV c. MAJ-2130, Generator Fuel Filter Inlet gas PCV 5. Place the tripped safety system devices in bypass (flag device as appropriate) Rev: 2 Date: 6/11/13 Page 7 of 13 HI 595 CF & D

8 6.
