FUEL LINES All Fuel Line construction is Double Wall Fibcrgiass. VEEDER ROW-TLS 350 MODEL/SIMPLLICITY 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 Vecder-Root (V-R) in Simsbury Connecticut, which would receive audible and visual alarms and provide corrective actions end tracking, in the event of leak detection. rhis system is interfaced to the manufactc.rers computer system via satellite dish or phone line. The communication status is checked monthly by V-R,The expected V-R a:arm response time is 15 minutes 'rom the tirne the facility goes into alarm and Simsbury starts the corrective actions. The monitor retains 1.2 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 "Lint 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 installAtioii service contractor (Service Station Systems 1-800-628-5310)would provide the training necessary to operate she tank and line monitoring system per the manufacturer guidelines. I he 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 Sl-I&E Compliance Coordinator. Optional facility audible and visual alurms can alto be programmed, but this would take the system out of the remote monitoring nrode, which leaves the facidity operator responsible for calling V-R fear q0 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) munitoring of the fuel tanks, Pressurized Line Leak Detection (PLLD)of the fuel lines and continumis annular interstice monitoring at double walled facilities containment In the event that a leak is detected, the system provides automatic notification through Elie 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 tate first two weeks of the following month by V-R. The operaring,faciliry 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. Tunica Eme-11 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. I'herc 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 et)ntainment would be performed per Local and State raduirements. Pressurized Fuel Lines. Continuous electronic moniroring of the dry secondary containment within the turbine sump, positive shutdown if a Irak is detected. Also PLLD continuous electronic testing 3.0 2Ph (positive shutdown)and 02 gph(rnonthly/alann), 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 io V- R, which would in turn contact their srrviee contractor for investigation and repair. Clean up of the secondary containment would be performed per Local and State requirements.
