SAN s10 A Q U I N Environmental Health Department <br /> — COUNTY- <br /> 5, Provide written notification to ust@sjgov.org to arrange the following inspection appointments. <br /> All appointments must be scheduled 48 hours in advance. <br /> PRIOR TO BACKFILL <br /> a) Inspection of tank for brine leaks prior to tank placement in excavation . All tank pre-installation tests <br /> shall be performed according to tank manufacturer instructions. <br /> b) Verification of tank set, anchorage, appropriate backfill, and appropriate additional corrosion protection <br /> of tank anchors (turnbuckles, eye bolts, etc. ) . Additional corrosion protection is required on all exposed <br /> metal prior to covering . <br /> c) Primary tank test, according to manufacturer's specifications. <br /> d) Primary piping soap test of all piping and penetrations (product, vapor recovery, and vent) : One-hour <br /> pneumatic pressure test at 110% of operating pressure, or 40 psi , whichever is greater, in accordance <br /> with manufacturer installation instructions. <br /> e) Verification of secondary piping slope at 1 /8 inch per foot or greater, to a containment sump with an <br /> audible/visual alarm . <br /> f) Secondary piping soap test of all piping and penetrations (product, vapor recovery, and vent): One- <br /> hour pressure test at the manufacturer's recommended specification . <br /> g) Verification of all pipe setbacks, cross-overs, and burial depth according to the manufacturer's <br /> installation instructions and verification of appropriate piping backfill . <br /> h) Integrity testing of all sumps per the manufacturer's installation instructions. <br /> I) Verification of brine type and witnessing of brine addition. <br /> PRIOR TO FIRST FUEL DELIVERY <br /> j) Verification of leak monitoring communication for all installed vacuum , pressure, or hydrostatic (VPH) <br /> components including piping, sumps, under dispenser containment sumps (UDCs), and all chase lines. <br /> Communication at end points of each vacuum zone and each vacuum monitored sump must be <br /> verified independently in operating condition. <br /> k) Verification of the dispenser footprints contained by the UDCs. Any potential leaks from piping and <br /> fuel filters must drain directly into UDCs. <br /> I) Enhanced Leak Detection (ELD) testing , after facility is in operating condition . Appropriate test <br /> notification, tester certifications, and test method disclosure is required . Passing ELD test results must <br /> be received prior to receiving fuel . <br /> m) Verification of VPH components installation (shroud boots and band clamps for spill containers, <br /> appropriate rubber-type gasket or clamps on lids on all fill, vent and STP sumps, etc.). <br /> n) Verification of overfill prevention : Measurement of drop tubes to verify 95% tank volume shut off and/or <br /> verification that external audible/visual alarm activates when tank is 90% full. <br /> o) Spill bucket test: Verify minimum 5-gallon capacity and pass a one hour hydrostatic test (or equivalent). <br /> Proper drainage method must be verified. <br /> p) Monitoring system functionality: Functionality of the monitoring system must be verified to ensure it <br /> meets the requirements of California Code of Regulations (CCR) Title 23 and California Health & <br /> Safety Code (HSC) Chapter 6. 7. <br /> PRIOR TO FINAL APPROVAL <br /> q) Leak detector test, after first fuel delivery: Leak detector must be tested to confirm that the device can <br /> detects leak of 3 gallons per hour at 10 psi . Leak detector monitored line volumes shall be appropriate <br /> for the make and model of the installed leak detectors, and shall be verified at the time of installation . <br /> r) PRIOR TO FINAL APPROVAL: Monitoring system functionality, after first fuel delivery, in operating <br /> condition : Functionality of the monitoring system must be verified to ensure it meets the requirements <br /> of CCR Title 23 and HSC Chapter 6 .7. <br /> 2 of <br />
