SANJOAQUIN Environmental Health Department COUNTY- 5. 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 Elena Manzo at (209) 953-7699 for the following inspections. See permit inspection checklist for more information. All appointments must be scheduled a minimum of 48-hours in advance and are subject to inspector's availability. Li 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. Xerxes tank installation checklist must be submitted to the EHD prior to the final inspection. Li Verification of tank set, anchorage, appropriate backfill in lifts, and appropriate additional corrosion protection of tank anchors (turnbuckles, eye bolts, etc.). Additional corrosion protection is required on all exposed metal prior to covering. i-i Test of all primary UST(s) containment according to manufacturer's specifications. o Primary piping soap test of all piping and penetrations (product, vapor recovery, and vent) according to the manufacturer's installation instructions: One-hour pneumatic pressure test at 110%of operating pressure, or 40 psi, whichever is greater. Ei Secondary piping slope (at 1/8 foot per foot or greater) to a containment sump with an audible/visual alarm. [-i Secondary piping soap test of all piping and penetrations (product, vapor recovery, and vent).- One- hour pressure test at the manufacturer's recommended specification. • 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 all piping setbacks and burial depth according to the manufacturer's installation instructions. Verification of appropriate backfill and concrete installation. i-i Verification of leak monitoring communication for all installed vacuum, pressure, or hydrostatic(VPH) components including piping, sumps, UDCs, and all chase/crossovers. Communication at the termination point of each vacuum zone must be verified. All appropriate connections to facilitate communication testing must be present. Chase piping must VPH monitored and included in its respective product piping vacuum monitoring zone. Ei 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. Ei Enhanced Leak Detection (ELD) testing (after facility is in operating condition): appropriate test notification and test method disclosure is required VPH components installation verification (shroud boots for spill containers, band clamps for spill containers, fill, vent and STP sump rubber gaskets or clamps, etc.) D 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 this inspection. Ei Spill bucket test prior to first fuel delivery: Verify minimum 5-gallon capacity (with a calibrated container) and pass a one hour hydrostatic test (or equivalent). Proper drainage method must be verified. Ei 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)). Ei 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. 2 of 4
