- e. Also, the emergency battery lights may not provide adequate illumination for manual 'bteaker and transfer switch operations.
Answer: Staging PPE locally should be evaluated by opemtions and the adequacy of emergency lighting should be evaluated by fire protection. PPE is available close by in a dedicated locker on the 15 foot turbine hall. Flashlights are normally carried by ional flashlights are. available near by from a ne hall.

- 10. Attachment 4, Step 1.3,18 - The operator performing the procedure gets to this step only if the Bus 2A / 5A alignment is selected. This step is not addressed if the Bus 6A / 3A alignment is selected.
Answer: Answer: Operations should review the procedure and make any required changes. For the SBO/Appendix R diesef to perform it's safety fundion during a Station Blackout it is required to energize ONE 480V Bus. The procedure provides guidance to energize more than ONE 480 V Bus and so the SBO/Appendix R diesel is functional.

Answer; The CRS will Operators are tt-ained to verify adequate load capability remaining on a diesel prior to starting a load. There is information in the procedure that give the SBOlAppendix R diesels load ratings and directs that when starting equipment, coordination with the CRS will be necessary to ensure adequate generator capacity is available. The emergency procedures contain a list of loads with their associated KW values. There is enough training and procedural guidance to ensure that all required actions will be the SBQ/bppendix+ R diesel is functional, he Operator on which bus is required to be lined up.
