MONITORING PROCEDURES DOUBLE CONTINED PIPING <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 leak at of <br /> 3 gallons or more per hour at 10 lbs. per square inch of line pressure within 1 hour at more than one <br /> location with positive shut down. The line pressure monitor is capable of sensing a pressure loss in the <br /> system and disables the flow of product through the lines. All product lines are sloped down towards the <br /> tank, and if the pressure sensor is activated, any liquid in the annular space will flow backwards toward the <br /> sump area. There is a sensor in the sump area that detects any liquid present there. The system has both <br /> visible and audible alarms that are activated when there is liquid in the sump or detected in the secondary <br /> containment. At least annually, the system is capable of detecting a release from the primary piping <br /> equivalent to .1 gph defined at 150% 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 verify <br /> that there is a leak condition and then silence the audible alarm. The Operator or his designee will <br /> immediately contact Chevron dispatch and advise them of the situation so that they can contact the <br /> appropriate personnel who will follow the instructions outlined in the "Leak Response Plan", which is part of <br /> your Hazardous Material Management Plan. All follow up will be completed within the month the problem <br /> occurred. <br /> The monitoring system will be inspected daily. The Operator or an employee appointed by the Operator will <br /> follow the same procedures as outlined for monitoring the double contained product 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 manufacturer's <br /> instructions. <br /> Chevron Maintenance Dispatch (24 Hour) 1-800-423-3528 <br />
