PENDIX B - Page 16.3 <br /> 3. The TLM will be able to detect (in the tank integrity mode) a minimum <br /> of a 0.20 gallon per hour leak while compensating for temperature <br /> changes within the tank with a probability of leak detection of 95 <br /> percent and probability of false alarms of 5 percent; <br /> e <br /> 4. The TLM system will be Level TRU (Model No. 10600) by Environment and <br /> Safety, Inc. , Veeder-Root TLS-350 with magnetostrictive .probe, or <br /> equal ; <br /> 5. Install overspill protection device at each tank. The overspill <br /> protection device will be Skyway (Model No. 85000) , Emco Wheaton <br /> A1003, or equal <br /> 6. No pipeline leak detector is required because both pumps are suction-type; <br /> 7. Install only one check valve in the suction line directly below and <br /> as close as practical to the suction pump. Remove any other existing <br /> check valves. <br /> GROUNDWATER <br /> This facility is located in the San Joaquin Valley Groundwater Basin.
