4.8.1.1.2 Each diesel generator shall be demonstrated OPERABLE:

a. At least once per 31 days on a STAGGERED TEST BASIS by:
1. Verifying the fuel level in the day fuel tank.
2. Verifying the fuel level in the fuel storage tank.
3. Verifying the fuel transfer pump can be started and transfers fuel from the storage system to the day tank.

5. Verifying the generator is synchronized, loaded to 11250 kW, and operates for 160 minutes.
6. Verifying the diesel generator is aligned to provide standby power to the associated emergency bussas.
7. Verifying that the automatic load sequencer timer is OPERABLE with the interval between each load clock within i 10's of its design interval.
5. At least once per 92 days by verifying that a sample of diesel fuel from the fuel storage tank is within the acceptable limits specified in Table 1 of ASTM 0975-81 when checked for viscosity, water and sediment.
