OVERFILL/ SPILL PROTECTION & CLEANUP 1. DELIVERIES/GAUGING Dealer is to 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. 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 3 gallons per minute alerting the driver of a potential overfill condition. In the event that this occurs, the following actions will be taken: 1. The delivery truck driver shall turn off the petroleum product supply at the truck, leaving the hose fully connected to the tank fill pipe and the truck. 2. The small amount of petroleum product remaining in the hose shall be slowly drained into the tank. Since the ball float valve is 2 to 3 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 ccupletely drain through the fill pipe into the tank. 3. 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 regaining small amount of petroleum product will be properly contained. 3. WASTE OIL TANK 1. -. Station is equipped with waste oil buckets which hold a maximLmt capacity of 3 gallons (about 3 to 4 cars' worth of waste oil) . 2. Prior to dining any waste oil, dealer is to gauge the tank to assure that holding capacity is greater than that which will be put into the tank. 3. Waste oil is poured directly through fill/pump out pipe, using a funnel. Should any waste oil spill during this operation, it will be properly contained using absorbent materials. 4. CLEAN-UP/RECORDS 1. Small spills (less than 1 gallon and only requiring 15 minutes to clean up) shall be cleaned up using absorbent materials. 2. Larger spills occurring during product delivery shall be reported to the terminal by the dealer and/or by delivery truck driver. The terminal supervisor will notify a local petroleum maintenance contractor who is equipped with a N.F.P.A. approved type hand pump, vacuum and transport container. Large spills not caused by delivery shall be reported imTiediately to your rep. 3. Spills shall be cleaned up within 8 hours of detection, returned to local terminal and/or disposed of in a lawful manner. 4. Dealer shall record all spills whether it is due to delivery overfill or accidental spillage, which exceeds approximately one gallon, and action taken on the "Unauthorized Release Report" (attached) , and send it to UNOCAL within 24 hours. 5. Large spills (more than 1 gallon) must be reported to the local agency indicated on the cover sheet within 24 hours. If the spill is large enough to pose a significant hazard, it must also be reported to the California office of Emergency Services at 800-852-7550. IN CASE OF EMER=CY CALL 9-1-1. Page 7 of 10
