DELIVERIES/GAUGING a. Dealer is responsible to ensure that the delivery he or she requests is not in excess of the tank capacity, taking into consideration the amount currently in tank. Driver is to gauge tank to assure capacity is available for the entire load and must remain in attendance during the entire delivery to monitor the operation. b. Each tank will also be equipped with its own electronic in -tank gauge. 2. BALL VENT LINE FLOAT SYSTEM (Only for double-wall tanks installed after July 1986.) The ball float valve system installed with the tank substantially prevents the possibility of overfill occurring. If the tank is filled to the ball float level, the petroleum product delivery will be cut to three gallons per minute alerting the driver of a potential overfill condition. In the event that this occurs, the following actions will be taken: a. The delivery truck driver shall turn off the petroleum product supply at the truck, leaving the hose fully connected to the tank fill pipe line and the truck. b. The small amount of petroleum product remaining in the hose shall be slowly drained into the tank. Since the ball float valve is two to three inches below the top of the tank, there remains a 100+ gallon capacity within the tank at the moment when the ball float closes off delivery. The bleed hole in the ball float valve allows ✓� the remaining petroleum product in the hose to completely drain through the fill pipe into the tank. C. The hose shall be disconnected from the fill pipe only when it has fully drained. In the event that spillage occurs upon hose disconnection, the remaining small amount of petroleum will be properly contained. 3. AUTOMATIC HIGH LEVEL SHUT-OFF SWITCH a. Each product tank will be equipped with an OPW 61 -SO automatic shut-off switch located near the top of the tank within the submerged fill tube. When product level is two to three inches below the top of tank a float is actuated thereby stopping product flow into the tank through the fill tube. 4. CONTAINMENT AT TANK FILL RISER a. If a spill occurs during delivery or upon disconnect of the truck delivery hose, up to twenty gallons of product will be contained in the spill containment fill box: round fil-spill containment box. A spring loaded valve assembly with a pull chain allows product to drain throughout a %" diameter hose into tank. b. A leak occurring at the tank pump sump basin will be contained by means of a 42" fiberglass collar made by the tank manufacturer. A leak in this area will sound an audible and visual alarm. F
