dwdw AUTOMATIC TANK LE ONITORING CONTINUOUS ELECTRONIC MONITORING OF TANKS AND PIPING TANKS All Underground Fuel Storage Tanks are Double Wall Fiberglass construction. FUEL LINES All Fuel Line construction is Double Wall Fiberglass. VEEDER ROOT-TLS 350 MODEL/SIMPLICITY TANK& LINE MONITOR The design of this unit and the Simplicity Service Offering is to provide 24 hour remote tank and line compliance monitoring through Veeder-Root (V-R) in Simsbury Connecticut, which would receive audible and visual alarms and provide corrective actions and tracking, in the event of leak detection. This system is interfaced to the manufacturers computer system via satellite dish or phone line. The communication status is checked monthly by V-R. The expected V-R alarm response time is 15 minutes from the time the facility goes into alarm and Simsbury starts the corrective actions. The monitor retains 12 months of alarm history. The facili receives audible and visual alarms at the TLS 350 console, which reflect (1) lost communication, "Autodial Failure" and/or (2) gross line failure "Line Leak Shutdown." The facility personnel would call V-R for these events. Autodial Failure will cause the TLS 350 to come out of the remote monitoring mode and all alarms/warnings will occur on-site and will be responded to by on-site personnel. If power is removed from the V-R monitoring panel, the facility will not be able to pump fuel. The authorized installation service contractor (Service Station Systems 1-800-628-5510)would provide the training necessary to operate the tank and line monitoring system per the manufacturer guidelines. The facility operator is responsible for daily inspection of the monitoring panel (Alarm Panel Test Log - pending Agency requirements) and corrective actions indicated above and maintaining monthly and annual tests/reports on-site. For additional compliance items/reports, contact Shell's HS&E Compliance Coordinator. Optional facility audible and visual alarms can also be programmed, but this would take the system out of the remote monitoring mode, which leaves the facility operator responsible for calling V-R for all alarm conditions and logging all events and corrective actions manually (not reliable, not recommended). All component parts are LG- 113 approved. TANK AND LINE TESTING The Veeder Root (V-R) system provides electronic Continuous Statistical Leak Detection (CSLD) monitoring of the fuel tanks, Pressurized Line Leak Detection (PLLD) of the fuel lines and continuous annular interstice monitoring at double walled facilities containment.In the event that a leak is detected, the system provides automatic notification through the phone line or satellite dish to V-R. Hard copies of monthly tank and line test results are to be mailed to the facility within the first two weeks of the following month by V-R. The operating facility is responsible to maintain these compliance reports on site. The TLS 350 is annually inspected, repaired and certified operational by an authorized service contractor. The certification is sent to the local regulatory agency. Tanks (Fuel): Continuous electronic monitoring of the wet or dry annular/interstice and CSLD, continuous electronic testing at 0.2 gallon per hour (gph). A malfunctioning tank will result with an alarm automatically transmitted to V-R, which would in turn contact their service contractor for investigation and repair. There would be no fuel leak to ground in the event that the primary tank failed unless the secondary, were to also fail. Clean up of the secondary containment would be performed per Local and State requirements. Pressurized Fuel Lines: Continuous electronic monitoring of the dry secondary containment within the turbine sump, positive shutdown if a leak is detected. Also PLLD continuous electronic testing 3.0 gph (positive shutdown), 0.2 gph (monthly/alarm) and 0.1 gph (annually/alarm), in combination with a turbine sump liquid sensor. If a gross leak alarm occurred here, the result would be fuel line shut down with no leak to ground [(Dry) annular/interstice]. A malfunctioning fuel line will result with an alarm automatically transmitted to V-R, which would in turn contact their service contractor for investigation and repair. Clean up of the secondary containment would be performed per Local and State requirements. If equipped, remote fill lines at the tank inlet are contained and continuously monitored (alarm). Under Dispenser Containment: Continuous electronic liquid sensor, designed to shut off the dispenser in the event of leak detection. VR 322 Turbine Sump Containment: Continuous electronic liquid sensor designed to turn off the turbine in the event of leak detection. VR 208 Tank Overfill Protection: Flapper valve with flow shut-off at 95%, located at the fill riser.
