i <br /> MONITORING AND RESPONSE PLAN -X <br /> ARCO PRODUCTS COMPANY FACILITY WITH <br /> SECONDARY CONTAINMENT OF <br /> UNDERGROUND STORAGE TANKS &PRODUCT LINES WITH <br /> SUBMERSIBLE PUMP SHUTDOWN <br /> ARCO Facility: _6313 Address: 1100 South Main Street <br /> Manteca. California <br /> This plan is designed to meet the monitoring and response requirements of Section 2632, Article 3, <br /> Title 23, CCR. <br /> 1. MONITORING EQUIPMENT <br /> Secondarily contained storage tanks and lines at this facility are monitored by a continuous electronic <br /> leak detection system which consists of an alarm panel, sensors and associated electronics. Liquid <br /> sensors are installed in the annular space of each double wall tank and product line piping sump. <br /> Whenever a sensor detects the presence of a liquid there is both a visual and audible alarm at the <br /> control panel. In addition, the continuous monitor on the product piping system will shut down the <br /> pump and activate the alarm system when a release is detected, or if the continuous product piping <br /> monitoring system fails or is disconnected, the pumping system will shut down. <br /> Automatic line leak detectors are installed on the secondarily contained pressurized product piping. <br /> The line detector will detect a loss of pressure in the product lines and restrict the flow of product. <br /> 2. MAINTENAKE SCIJEDULE <br /> The continuous electronic leak detection system including line leak detectors will be inspected <br /> according to the manufacturer's instructions by an outside contractor once during each calendar year. <br /> 3. ROUTINE MONITORING PROCEDURE <br /> On a daily basis the facility operator shall: <br /> A. Inspect the control panel for visual and audible alarm signals to confirm that the unit is operating. <br /> B. Inspect island and tank fill areas for signs of spillage or petroleum sheen. <br /> C. Record the inspection observations on the Daily Visual Monitoring Log(Form APCC-765: <br /> attached). <br /> -1- 4225.010[SK/sml <br />
