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 <br />product piping system will shut down the pump and activate the alarm system when a <br />release is detected or if the continuous product piping monitoring system fails or is <br />disconnected, the pumping system will shirt 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 <br />the flow of product. <br />2. MAINTENANCE SCHEDULE OF MONITORING EQUIPMENT <br />The continuous electronicleak detection system including line leak detectors will be <br />inspected according to the manufacturer's instructions by an outside contractor once during <br />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 <br />the unit is operating. <br />B. Inspect island and tank fill areas for signs of spillage or petroleum shecn. <br />C. Record the inspection observations on the Daily Visual Monitoring Log <br />(Form APPC-765: attached.) <br />
