SAN JOAQUIN COUNTY Environmental Health Department All primary containment including any integral secondary containment system must be certified by an independent testing organization and labeled as required by the organization (Title 23 Chapter 16, 2631(b); (UL, ULC, ANSI, API, ASTM, etc. See Title 23 Chapter 16 Table B for complete list.) Pursuant to Underwriters Laboratories Inc (UL) listing requirements, only those products bearing the UL mark will be considered listed. ANY PART/PRODUCT NOT MARKED WITH THE UL LABEL OR ANOTHER LISTED TESTING ORGANIZATION WILL BE REJECTED. All secondary containment system which is not an integral part of the primary containment shall be designed and constructed according to an engineering specification approved by a state registered professional engineer or according to a nationally recognized industry code or engineering standard (Title 23 Chapter 16, 2631(d)). 6. Contact John Alaniz (ICC inspector) at (209) 468-3147 for the following inspections. See the permit inspection checklist more information. All appointments must be scheduled 48 hours in advance. ❑ Inspection of tank vacuum gauge or inspection for brine leaks prior to tank placement in excavation. All tank's pre -installation tests shall be performed according to tank's manufacturer instructions. ❑ Verification of tank set, anchorage, appropriate backfill, and appropriate additional corrosion protection of tank anchors (turnbuckles, eye bolts, etc.). Corrosion protection is required on all exposed metal prior to covering. ❑ Test of the primary UST(s) containment according to manufacturer's specifications. ❑ Primary piping soap test of all piping and penetrations (product, vapor recovery, and vent): One-hour pneumatic pressure test at 110% of operating pressure, or 40 psi, whichever is greater. ❑ Secondary piping slope (at 1/8 foot per foot or greater) to a containment sump with an audible/visual alarm. ❑ Secondary piping soap test of all piping and penetrations (product, vapor recovery, and vent): One- hour pressure test at the manufacturer's recommended specification. ❑ Verification of all pipe setbacks and burial depth according to the manufacturer's installation instructions. Verification of appropriate backfill. ❑ Integrity testing of all sumps per the manufacturer's installation instructions prior to backfill, and brine type verification and brine addition prior to backfill. ❑ Verification of leak monitoring communication for all installed vacuum, pressure, or hydrostatic (VPH) components including piping, sumps, UDCs, and all chase/crossovers; communication, at end point(s) of each vacuum zone termination must be verified. All appropriate connections to facilitate communication testing must be present. ❑ Verification of the dispenser footprints contained by the under dispenser containment sumps (UDCs), any potential leaks from piping and fuel filters must drain directly into UDCs. ❑ Enhanced Leak Detection (ELD) testing (after facility is in operating condition): appropriate test notification and test method disclosure ❑ VPH components installation verification (shroud boots for spill containers, band clamps for spill containers, fill, vent and STP sump rubber gaskets, etc.) ❑ Overfill prevention verification prior to first fuel delivery: Measurement of drop tubes to verify 95% tank volume shut off and/or verification that external audible/visual alarm activates when tank is 90% full. An accurate drop tube and tank level gauge calculation must be provided to the EHD prior to scheduling an overfill prevention verification inspection. ❑ Spill bucket test prior to first fuel delivery: Verify minimum 5 -gallon capacity and pass a one hour hydrostatic test (or equivalent). Proper drainage method must be verified. ❑ Monitoring system functionality prior to first fuel delivery: Functionality of the monitoring system must be verified to ensure it meets the requirements of Title 23 California Code of Regulations and the Health & Safety Code (functionality and communication of hydrostatic, vacuum, and liquid sensors in tanks, sumps and under dispenser containments (UDCs)). ❑ Leak detector test after first fuel delivery: Leak detector must be tested to confirm that the device can detect a leak of 3 gallons per hour at 10 psi. Leak detector monitored line volumes shall be appropriate for the make and model of the installed leak detectors, and shall be verified at the time of installation. ❑ Monitoring system functionality after first fuel delivery: Functionality of the monitoring system must be verified to ensure it meets the requirements of Title 23 California Code of Regulations and the Health & Safety Code (functionality of vacuum sensors and vacuum zones communication). 2 of 4
