STANDARD OPERATING INSTRUCTIONS NO. 2 MAINTENANCE AND OPERATION INSTRUCTIONS FOR POL FACILITIES PARRY ISLAND valves V13 and 14 thence to the loading rack through valve V1ll2 and quick opening valve V111i into tank truck. A line also supplies the powerhouse and laundry through valve V113. During the unloading operation, valves V2 to V15 are closed, and the required tank outlet valves, pump suction and discharge valves, and valve V115 are opened, After the truck has been filled and the pumps cut off, valve V15 should be opened to relieve the pressure on the system back into the tanks. NOTE: Valve V15 must always be closed when a truck is being loaded to prevent the pump from circulating the liquid back through the tanks thus giving the wrong meter reading. GASOLINE LOADING OPERATION Gasoline is delivered to the POL tank farm by tanker ship which anchors off shore and connects to a flexible line at the marker buoy. This flexible line, in turn, is connected to a steel submarine pipe which delivers the gasoline to Gasoline Dehydrators Nos. 3 and 4 through valve V55, Strainer 5-2, Pressure Regulator valve V56, and valves V57 and V58. (Salt water in the submarine line is drained back to the lagoon through valve V114). The entrained water is separated at the dehydrators; the gasoline then goes to deaerator No, 2 through valves V59 and V60, and Pilot operated motor valves V6l and Vé62, 2-5
