M• RING PROCEDURES DOUBLE CON Et TING <br /> CONTINUOUS ELECTRONIC MONITORING 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 />
