15 RA-EP-02270 Revision 02 ATTACHMENT 2: DBAB VENTILATION ZONES AND EQUIPMENT LOCATIONS Page I of 4 Ventilation System - The DBAB first floor ventilation system consists of two air handling units, each supplying air to two separate zones. These units are controlled from the Ventilation System Control Panel. The control panel is located on the west wall of the East Mechanical Room.'

Ventilation Zone One - consists of the north half of the first floor (excluding West Mechanical Room and Computer Room), the Site Emergency'Operations Center and the Public Relations Office. It is normally serviced by the ventilation unit in the East Mechanical Room.

Ventilation Zone Two - consists of the south half of the first floor (excluding the Lobby and Records Management). It is normally'serviced by the ventilation unit in the West Mechanical Room.

The ventilation controls include an Incident Control switch and a By-Pass Control switch.

• Incident Control switch causes the ventilation system to filter and recirculate the air.

• By-Pass Control switch shifts the Zone Two air recirculation system to Zone One, if the Zone One ventilation equipment fails. -:

Ventilation Zone Three -consists of the computer equipment room. Zone Three is serviced by a self-contained unit. Make-up ventilation is provided from Zone One distribution system.

Ventilation Zone Four - consists of the Records Management area and vault. Zone Four is serviced by a self-contained unit with Ventilation air provided from the Zone One air distribution system'.

Ventilation Zone Five - consists of the Lobby, Mezzanine and DBAB 2nd floor, which is serviced by two air handling units on the DBAB 2nd floor.

PLACING THE EMERGENCY WATER SYSTEM IN SERVICE Initials

1. Isolated the normal domestic water system from the emergency water system by:

a. CLOSE valve DW-2, DBAB Supply Isolation

b. CLOSE valve DW-17, Pump Bypass

c. CLOSE valve DW-19, Tank Bypass

2. Slowly open valve DW-13, Tank Vent valve (located near the floor drain north of the tank) to vent off the storage tank pressure to floor drain. DW-13, Tank Vent valve shall remain open during operations of the Domestic Water Pump to service as a vent path for the storage tank

3. Check that the pressure gauge located upstream of DW-14, Gauge Isolation valve (about 12 inches above DW-2, DBAB Supply Isolation valve) is reading zero to verify that the system is depressurized.

4. Unisolate storage water tank sight glasses by opening sight glass isolation valves:

a. OPEN valve DW-9, Upper Sight Glass Isolation

b. OPEN valve DW-10, Upper Sight Glass Isolation

c. OPEN valve DW-1 1, Lower Sight Glass Isolation

d. OPEN valve DW-12, Lower Sight Glass Isolation.

5. Unisolate the Domestic Water Pump by opening valves:

a. OPEN valve DW-22, Pump Suction

b. OPEN valve DW-15, Pump Discharge

6. Start the Domestic Water Pump by CLOSING local disconnect switch 19-21A located the south wall above the pump, i.e. move the knife switch to the "ON" position.

7. Verify that that the Domestic Water Pump is operating by opening the faucet located on the east wall of the Mechanical Room between the pressure tank and the hot water heater. Run tap water until the pump starts. Turn off the faucet and observe the gauge until the pump shuts off. The pump should start at 30 psig +/- 4 pounds and shutoff at 50 psig +/- 4 pounds.

8. Notify the Emergency Facility Services Manager and the Emergency Offsite Manager that the DBAB domestic water storage tank has been isolated from the normal supply and placed in service.

b. CLOSE valve DW-22, Pump Suction

4. Unisolate the system bypass by:

a. OPEN valve DW-17, Pump Bypass

b. OPEN valve DW-19, Storage Tank Bypass.

5. Throttle open DW-2, DBAB Supply Isolation valve and observe the Domestic Water Tank level increase slowly.

6. When the tank level indicates full by the sight glass close DW-2, DBAB Supply Isolation valve

7. Isolate the storage tank sight glasses by closing sight glass isolation valves:

a. CLOSE valve DW-9, Upper Sight Glass Isolation

b. CLOSE valve DW-10, Upper Sight Glass Isolation

c. CLOSE valve DW-I 1, Lower Sight Glass Isolation

d. CLOSE valve DW-12, Lower Sight Glass Isolation -

8. Throttle open DW-2, DBAB Supply Isolation valve and slowly fill the Domestic Water Tank until water is observed flowing from the vent line downstream of DW-13, Tank Vent valve.

9. When water is observed flowing from DW-13, Tank Vent, then CLOSE DW-13, Tank Vent

10. Slowing fully OPEN DW-2, DBAB Supply Isolation valve.

11. Advise the Emergency Offsite Manager that the domestic water system has been returned to a normal lineup.
