UST Monitoring • Response Tank Monitoring Equipment Date: November 12, 1997 Facility Name: Pacific Bell Facility ID: UE148 Vecdcr Root - TLS-350 inventory n actof the itterm tank monitoring product for rd with tnk oninuos product moi orig provded hogh the nslatioof te TLS350 Tank Level accomplished manufactured by Veeder-Root. The TLS-350 consists of a Computerized Inventory Monitor (CIM) and one Digital Sending Probe (DSP) for each tank being monitored. The highly accurate, all electronic probe has no moving parts for greater accuracy and less maintenance than other electro-mechanical, float-type devices. A single CIM can handle multiple probes and continuously monitor each one, analyzing their signals for liquid, temperature, depth and water level. Based on this input, the CIM computes volumes and stores this information for remote polling. The RE-232C Serial Interface Communication port permits access to TLS-350 information from remote locations via telephone lines. This serial interface is capable of handling up to 16 polling stations from centralized remote locations. The output of the serial port can be formatted for teletype or computer (IBM-PC) interface. The TLS System has four modes of operation - Leak Detection, Tank Detection, Interstitial/Piping Sump Lead Detection and Automatic Delivery Reporting. When the leak monitor mode is activated, the TLS System continuously monitors fuel levels in each tank and can detect losses of 0.2 gph. An hourly report on each tank shows temperature-compensated inventory changes to 0.1 gallon based on inventories when the tank leak mode is initiated. The Leak Monitor is activated through a push-button mounted on the front panel, or remotely through the RS-232 Telecommunications Interface. The Tank Inventory Report presents the current status of each tank. It provides station location, date and time, volume and level of fuel, water level and temperature. Interstitial/Piping Sump Leak monitoring will be provided using two liquid sensors placed in the double wall tank annular space and in the tank manhole space. The LED display on the TLS console will flash indicating the alarm cause and location. The Automatic Delivery Increase Report features are 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 of inventory. Alarm Conditions Pacific Bell's UST/IS database system automatically calls the TLS monitoring system and "reads" alarms and tank data four times per day. The alarms are investigated by our personnel in the centralized Fuel Administration Center located in Sacramento, California. In the event the on site TLS device panel indicates an alarm condition the Power Room/Fleet personnel are instructed via an "In Case of Alarm" Notice posted on the device panel to contact the following: Power Room Supervisor, Site Manager, Real Estate Facility Engineer, Fuel Administrator Center. Recertificationof • All equipment used in implementing the monitoring program shall be installed, calibrated, operated and maintained in accordance with the manufacturer's instructions, including routine maintenance and service checks. The system is inspected once per calendar year by a third party in accordance with Article 5, Title 23, CCR. Copies of the recertification report shall be sent to the administering agency and copies will be maintained on site. pg. 4
