Stockton Service Cen* PG&E UNDERGROUND TANK MONITORING REQUIREMENTS A TLS-2501 Ronan Series X76S Tank Monitoring System was installed for the double-wall underground tanks. A Leak Alert Model number LA-08 was installed to monitor the waste oil and the Hydraulic oil double-wall underground tanks. The TLS- 250/Ronan monitor the inventory of gasoline and diesel and utilizes the considerations of volumes, pressure, temperature, and amount of water condensation in the tank to detect leaks in the tank or piping. This electric system is also an automatic in tank level monitor to accurately determine existing inventories at any time of gasoline and diesel. The TLS-250 printer or data output terminal is located in the Autoshop and prints out a daily detection notice. The Leak Alert Model number LA-08 is designed to monitor the product plus the annular space in both the waste oil and the hydraulic oil tanks. The All monitor systems include an alarm which sounds off in the Autoshop. Department employees are prepared to respond to the emergency through procedures in the Emergency Response Plan. The TLS-250 is to be calibrated and tested on a annual basis. Additionally the piping is tightness tested annually. Training for the monitoring system and the tank system are done through review of the owners manual and a hands-on review of the monitoring system performed by the calibration tester. 1 . This device is a dual-channel system, a internal tank level probe is used to detect leaks of liquid from the tank. It is also equipped with an audible "BUZZER ALARM" to alert operators of a possible leak. The leak detection report can furnish a "pass/fail" summary of the test results. The system includes eight auxiliary input contacts to monitor other external vapor or liquid detection systems.
