)RING PROCEDURES DOUBLE CONI <br />NUOUS ELECTRONIC MONITORI <br />VED PIPING <br />SUMPS <br />DOUBLE CONTAINED PIPING <br />INTERSTITIAL SPACE MONITOR: X LIQUID <br />SUMP MONITOR: X LIQUID SENSOR Veeder-Root TLS -350 Single Float Series 7943 <br />EQUIPMENT AT THIS FACILITY IS: Veeder-Root TLS -350 PLLD Series 8484 <br />All double contained piping is continuously monitored electronically by a system that can sense a <br />leak at of 3 gallons or more per hour at 10 lbs. per square inch of line pressure within 1 hour at more <br />than one location with positive shut down. The line pressure monitor is capable of sensing a <br />pressure loss in the system and disables the flow of product through the lines. All product lines are <br />sloped down towards the tank, and if the pressure sensor is activated, any liquid in the annular <br />space will flow backwards toward the sump area. There is a sensor in the sump area that detects <br />any liquid present there. The system has both visible and audible alarms that are activated when <br />there is liquid in the sump or detected in the secondary containment. At least annually, the system <br />is capable of detecting a release from the primary piping equivalent to .1 gph defined at 150% <br />operating pressure. <br />RESPONSE PLAN <br />If the system goes into the alarm mode, the Operator or his designate will check the alarm panel to <br />verify that there is a leak condition and then silence the audible alarm. The Operator or his designee <br />will immediately contact Chevron dispatch and advise them of the situation so that they can contact <br />the appropriate personnel who will follow the instructions outlined in the "Leak Response Plan", <br />which is part of your Hazardous Material Management Plan. All follow up will be completed within <br />the month the problem occurred. <br />The monitoring system will be inspected daily. The Operator or an employee appointed by the <br />Operator will follow the same procedures as outlined for monitoring the double contained product <br />tanks. <br />PREVENTATIVE MAINTENANCE <br />The monitoring equipment shall be inspected and certified annually. Maintenance will be performed <br />annually or as needed. All work performed to the monitoring system will be in accordance to the <br />manufacturers recommendations. <br />TRAINING <br />Tank operators are trained on the proper operations of the monitoring equipment per the <br />manufacturer's instructions. <br />Chevron Maintenance Dispatch (24 Hour) 1-800-423-3528 <br />
