dwdw AUTOMATIC TANK LEVEL MONITORING <br /> CONTINUOUS 19CTRONIC MONITORING OF TAN4&M PIPING <br /> TANKS low <br /> All Underground Fuel Storage Tanks are Double Wall Fiberglass construction, <br /> FUEL LINES <br /> All Fuel Line construction is Double Wall Fiberglass, <br /> VEEDER ROOT-TLS 350 MODEL/SIMPLICITY TANK&LINE MONITOR <br /> The design of this unit and the Simplicity Service Offering is to provide 24 hour remote tank and line <br /> compliance monitoring through Veeder-Root (V-R) in Greensboro, North Carolina, which would receive <br /> audible and visual alarms and provide corrective actions and tracking, in the event of leak detection. This <br /> system is interfaced to the manufacturer's computer system via satellite dish or phone line. The <br /> communication status is checked monthly by V-R: The expected V-R alarm response time is 15 minutes <br /> from the .time the facility goes into alarm and Greensboro starts the corrective actions. The monitor <br /> retains 12 months of alarm history. The facili receives audible and visual alarms at the TLS 350 <br /> console, which reflect(1) lost communication, "Autodial Failure"and/or(2)gross line failure"Line Leak <br /> Shutdown." The facility personnel would call V-R for these events. Autodial Failure will cause the TLS <br /> 350 to come out of the remote monitoring mode and all alarms/warnings will occur on-site and will be <br /> responded to by on-site personnel. If power is removed from the V-R monitoring panel, the facility will <br /> not be able to pump fuel. The authorized installation service contractor(Service Station Systems 1-800- <br /> 628-5510) would provide the training necessary to operate the tank and line monitoring system per the <br /> manufacturer guidelines. The facility operator is responsible for daily inspection of the monitoring'panel <br /> (Alarm Panel Test Log - pending Agency requirements) and corrective actions indicated above and <br /> maintaining monthly and annual tests/reports on-site. For additional'compliance items/reports, contact <br /> Shell's SH&E Compliance Coordinator. Optional facility audible and visual alarms can also be <br /> programmed, but this would take the system out of the remote monitoring mode, which leaves the facility <br /> operator responsible for calling V-R for all alarm conditions and'logging all events and corrective <br /> actions manually(not reliable, not recommended). All component parts are LG-113 approved. <br /> TANK AND LINE TESTING <br /> The Veeder Root (V-R) system provides electronic Continuous Statistical Leak Detection (CSLD) <br /> monitoring of the fuel tanks, Pressurized Line Leak Detection (PLLD) of the fuel tines and continuous <br /> annular interstice monitoring at double walled facilities containment. In the event that a leak is detected, <br /> the system provides automatic notification through the phone line or satellite dish to V-R. Hard copies of <br /> monthly tank and line test results are -to be mailed to the facility within the first two weeks of the <br /> following month by V-R. The operating facility is responsible to maintain these compliance reports on <br /> site. The TLS 350 is annually inspected, repaired and certified operational by an authorized service <br /> contractor. The certification is sent to the local regulatory agency. <br /> Tanks" (Fuel): Continuous electronic monitoring of the wet or dry annular/interstice and CSLD, <br /> continuous electronic testing at 0.2 gallon per hour(gph).A malfunctioning tank will result with an alarm <br /> automatically transmitted to V-R, which would in turn contact their service contractor for investigation <br /> and repair. There would be no fuel leak to ground in the event that the primary tank failed unless the <br /> secondary, were to also fail. Clean up of the secondary containment would be performed per Local and <br /> State requirements. <br /> Pressurized Fuel Lines: Continuous electronic monitoring of the dry secondary containment within the <br /> turbine sump, positive shutdown if a leak is detected. Also PLLD continuous electronic testing 3.0 gph <br /> (positive shutdown), 0.2 gph (monthly/alarm)and 0.1 gph(annually/alarm), in combination with a turbine <br /> sump liquid sensor. If a gross leak alarm occurred here, the result would be fuel line shut down with no <br /> leak to ground [(Dry) annular/interstice]. A malfunctioning fuel tine will result with an alarm <br /> automatically transmitted to V-R, which would in turn contact their service contractor for investigation <br /> and repair. Clean up of the secondary containment would be performed per Local and State requirements. <br /> If equipped, remote fill lines at the tank inlet are contained and continuously monitored(alarm). <br /> Under Dispenser Containment: Continuous electronic sensor, designed to shut off the dispenser in.the <br /> event of leak detection. <br /> Turbine Sump Containment: Continuous electronic sensors, designed to shut the turbine down in the <br /> event of leak detection. <br /> Tank Overfill Protection: Flapper valve with flow shut-off at 90%. <br /> 7/5/07 dwdw <br />
