UST Monitoring Plan • • <br /> Stockton Service Center <br /> VI. LEAK DETECTION RESPONSE PLAN <br /> The following Leak Detection Response actions will be initiated when a leak is either suspected or <br /> confirmed. <br /> A. GASOLINE OR DIESEL FUEL STORAGE TANKS (Veeder Root Model TLS-3501: <br /> 1. When the system is operating normally, the Green POWER indicator, located in the left-center of <br /> the front panel, will be lit <br /> 2. A leak will be suspected when a BUZZER ALARM sounds and a Red ALARM Light is lit on the <br /> tank-monitoring panel. The identification of the activated liquid sensor, in-tank probe, or product <br /> piping pressure transducer will be indicated in the L.E.D. display. The location of the activated <br /> sensor will be indicated on the paper tape printout and on the location map posted on the wall <br /> adjacent to the monitor. <br /> 3. Investigate the alarm by inspecting the appropriate sensor to determine if a leak has occurred or if <br /> storm water runoff has entered the containment. <br /> 4. If the sensor one of the tanks' annular spaces has triggered the alarm, and liquid is present in the <br /> annular space of the subject tank, obtain a sample, if possible, to determine whether the liquid is <br /> petroleum product or water. If product is found, start an in-tank leak test using the TLS-350. <br /> 5. If it has been determined that the alarm condition has been caused by a product leak—or- if the <br /> cause of the alarm condition cannot be determined, remove the tank from service pending <br /> confirmation of the cause of the alarm condition. <br /> 6. Contact one of the two PG&E people indicated below. Provide as much detailed information as <br /> possible.
