MONITORING PROCEDURES FOR DOUBLE WALL PIPING SYSTEMS <br />All double wall piping is sloped downward to a sump that is attached to underground storage tanks. In the event of a leak or <br />pressure loss a manual in-line leak detector is activated and will reduce product flow to 2 gallons per minute. The leaking product <br />will be contained within the doubled wall piping and will flow downward and terminate into a sump. The sump area is monitored <br />with a liquid sensing probe that will activate a visual and audible alarm system. <br />If the system goes into alarm, the station operator will check the alarm system panel and perform a test procedure to verify that <br />the system is not malfunctioning. If the system confirms a leak the operator is to immediately shut down the product and contact <br />the designated Shell representative and advise him/her of the situation so that they can follow the instructions outlined in the <br />"SHELL LEAK RESPONSE PLAN", which is part of this HAZARDOUS MATERIAL MANAGEMENT PLAN. <br />The system used at this facility is: VEEDER ROOT TLS -350 <br />The monitoring will be preformed on site by the authorized personnel below. <br />PREVENTATIVE MAINTENANCE <br />The monitoring equipment shall be inspected and certified annually. Maintenance will be performed annually or as <br />needed. All work performed to the monitoring system will be in accordance to the manufacturers recommendations. <br />RESPONSE PLAN <br />If a failure occurred in the piping systems annular space, the dealer will contact Service Station Services at 800-887-8009. <br />Service Station Systems will contact Shell Maintenance to determine the proper actions, which may include performing <br />an integrity test or calling a contractor to pump the product out of the sumps. The local agency will be properly notified <br />of the status of the piping. All follow up will be completed within the month the problem occurred. <br />TRAINING <br />Tank operators are trained on the proper operations of the monitoring equipment per the manufacturer's instructions. <br />RESPONSIBLE SHELL PERSONNEL The following personnel are responsible for performing monitoring or maintaining the <br />equipment. <br />NAME TITLE PHONE <br />Steve Griffen Manager Day 209-948-0574 <br />24hr 209-957-5461 <br />Jeff Granberry Project Engineer Work 510-675-6145 <br />Home 510-673-0753 <br />Jeff Byram District Engineer Work 510-675-6146 <br />Home 510-674-9413 <br />Dan T.
