d%vdw AUTOMATIC TANK LEVEL. MONI1OUNU q5-13 ieck � 5r"C-1G r v,,, CONTINUOUS ELECTRONIC MONITORING OF TANKS AND PIPING TANK5 Ail Underground Fuel Storage Tanks are Double Wall Fiberglass construction. FUEL LINES A:1 Fuel Line constnution is Double Wall Fiberglass. VF.EDER ROOT - TLS 350 MODEL / SIMPLICITY TANK & LINE MONITOR The design of this unit and the Simplicity Service Offering is to provide 24 hour remote tal=k and lire compliance monitoring through Veeder-hoot (V -R) in Simsbury Connecticut, which would roceive 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 iine. The communication status is checked monthly by V -R. The expected V -R a.arm response time is i 5 m=inutes from the time 'he facility goes into alarm and Simsbury starts the corrective actions. The monitor retains 12 months of alum history. The facility 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 cut] 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.$00-628-5510) would provide the training necessary to operate the tank and line monitoring system per the manufacturer guideiines. The facility operator is responsible for daily inspection of die monitoring panel (Alarm Panel Test Log - pending Agency requirements) and corrective actiuns indicated above and maintaining monthly and annual tests/reports on-site. For additional compliance itemsireports, contact Shell's SH&E Compliance Coordinator. Optional facility audible and visual Worms can also he programmed. but this would take the system out of the remote wonitoring mode, which /eaves the facility operator responsible for calling V-R.for all alarm conditions and iogging u/1 everts 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 ►.ontainment. 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 (Fuell: Continuous electronic monitoring of the wet or dry annular!interstice and CSL.D, 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 tate primary tank failed unless the secondary, were to also fail. Clean ap of the secondary containment would be performed per Local and State requirements. Pressurized Fuel Linea: Continuous electronic monitoring of the dry secondary containment within the turbine sump, positive shutdown if a leak is detected. A;so PLLD continuous electronic testing 3.0 gph (positive shutdown) and 0.2 gph (monthly/alarm), in combination with a turbine sump liquid sensor. If a gross leak alarm occurred here, the result would be fuel Iine shut down with n , leak to ground i(Dry) annular/interstice]. A ma:functioning 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 Frill lines at the tank inlet are contained and continuously monitored (alarm). tinder DispSnse_r Cuntxinment: C.0I1tinUOus electr,:•nic VR sensors designed to 5hut off the dispenser in the event of leak detection.
