10 losses. An hourly report on each tank shows temperature - Compensated inventory changes to 0.1 gallon based on inven- tories when the tank leak mode was initiated. An Inventory Loss Alarm feature can initiate a signal to alarm on the premises, or to the Switching Control Center (SCC) when a loss of 25 gallons occurs during any one-hour period. The Tank Inventory Report presents the current status of each tank. It provides station location, date and time, volume of fuel, level of fuel. water level and temperature. The Automatic Delivery Report feature is generated two minutes after fuel is delivered to the tank. The printout includes date. time, volume, and temperature before and after the increase and the net increase in inventory. The system is designed to prevent unauthorized use from out- side persons by a security code feature. 2. Precision Product Monitoring System Procedures A daily report listing the date and time, volume of fuel, level of fuel, water level and temperature for each tank will be polled from the Switching Control Center responsible for the office. These results will then be compared with the previous days results to identify any ongoing trends or discrepancies that would indicate that fuel leakage or water intrusion has occurred. These reports (printouts) will be reviewed and initialed daily by the responsible Switching Control Center person. The report will then be filed and retained by the SCC for a period of one year. The Switching Control Center person will compare and note the current fuel volume, fuel level and water level readings with the previous days results. A fuel volume decrease of more than 15 gallons or a decrease of more than 0.1 inch of fuel level potentially indicates a leaking tank. An increase in water level, fuel volume, and fuel level indicates that groundwater may be leaking into the storage tanks. If any discrepancy is noted that indicates a tank may be leaking, the Local Fire Department should be notified imme- diately. In addition, the tanks and/or piping should be leak -tested ("petro-tite" or equivalent) by a licensed con- tractor within five days. If the test is positive, the tanks and/or piping can be retested within five additional days. If a retest is positive, procedures to mitigate the oil leak should begin immediately. All leak surveillance and testing activities should be recorded and stored for three years with the oil spill inspection and surveillance records. RKE717P1428533
