❑ Brine addition and verification for brine leaks in the interstitial space of all sumps and <br /> UDC (s) prior to backfill . (Completed for UDCs, vent sump, and STP sumps) <br /> ❑ Verification of communication for all installed vacuum , pressure , or hydrostatic (VPH ) <br /> components <br /> ❑ Verification of the dispenser footprints contained by the under dispenser containment <br /> sumps ( UDCs) (Completed) <br /> ❑ Enhanced Leak Detection ( ELD) testing (after facility is in operating condition ) : <br /> appropriate test notification and test method disclosure <br /> ❑ VPH components verification ( lockable lids , shroud boots , band clamps , gaskets , <br /> etc . ) <br /> ❑ Overfill prevention verification : Measurement of drop tubes to verify 95 % tank volume <br /> shut off and/or verification that external audible/visual alarm activates when tank is <br /> 90 % full . <br /> ❑ Spill bucket test: Verify minimum 5-gallon capacity and pass a one hour hydrostatic <br /> test (or equivalent) . Proper drainage method must be verified . <br /> ❑ Monitoring system functionality prior to fuel delivery : Functionality of the monitoring <br /> system must be verified to ensure it meets the requirements of Title 23 California <br /> Code of Regulations and the Health & Safety Code (functionality of brine and liquid <br /> sensors in sumps and under dispenser containments ( UDCs) ) . (Completed) <br /> ❑ Leak detector test : Leak detector must be tested to confirm that the device can <br /> detect a leak of 3 gallons per hour at 10 psi . (Completed) <br /> ❑ Verification of concrete thickness at the tanks for compliance with buoyancy <br /> calculations . <br /> ❑ Fill sump integrity testing after repairs . <br /> ❑ Visual inspection of the UDCs to verify construction is in a manner to prevent vapors <br /> from entering the backfill . <br /> ❑ Visual verification of adhesive removal from the 87 fill sump vacuum tube . <br /> ❑ Verification of all fuel removal from 87 product , vent , and vapor recovery vacuum <br /> monitored secondary piping ; verification that primary piping is free of leaks . <br /> ❑ Monitoring system functionality : Functionality of the monitoring system must be <br /> verified to ensure it meets the requirements of Title 23 California Code of <br /> Regulations and the Health & Safety Code (functionality of vacuum and liquid " smart" <br /> sensors) . <br /> ❑ Final inspection and demonstration of automatic shut-down , as applicable . <br /> 7 .
