MONITORING AND RESPONSE PLAN - N <br /> ARCO PRODUCTS COMPANY FACILITY W ITA <br /> SECONDARY CONTAINMENT OF <br /> UNDERGROUND STORAGE TANKS & PRODUCT LINES WITH <br /> SUBMERSIBLE PUMP SHUTDOWN <br /> ARCO Facility: �0 Address ASS S °k9 <br /> S'tacV;Com � � <br /> This plan is designed to meet the monitoring and response requirements of Section 2632, <br /> Article 3, Title 23, CCR. <br /> 1. MONITORING EQUIPMENT <br /> Secondarily contained storage tanks and lines at this facility are monitored by a continuous <br /> electronic leak detection system which consists of an alarm panel, sensors and associated <br /> electronics. Liquid sensors are installed in the annular space of each double wall tank and <br /> product line piping sump. Whenever a sensor detects the presence of a liquid there is both a <br /> visual and audible alarm at the control panel. In addition, the continuous monitor on the product <br /> piping system will shut down the pump and activate the alarm system when a release is detected <br /> or if the continuous product piping monitoring system fails or is disconnected, the pumping <br /> system will shut down. <br /> Automatic line leak detectors are installed on the secondarily contained pressurized product <br /> piping. The line leak detector will detect a loss of pressure in the product lines and restrict the <br /> flow of product. <br /> 2. MAINTENANCE SCHEDULE OF MONITORING EQUIPMENT <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 <br /> year. <br /> 3. ROUTINE MONITORING PROCEDURE <br /> On a daily basis the facility operator shall: <br /> A.
