SANJ O A Q U I N Environmental Health Department <br /> COUNTY <br /> Health & Safety Code (functionality and communication of hydrostatic, vacuum, and liquid sensors in <br /> tanks, sumps and under dispenser containments (UDCs)). <br /> ❑ Receipt and upload of all required documentation prior to scheduling the final inspection. <br /> ❑ Leak detector test after first fuel delivery: Leak detector must be tested in operating condition to confirm <br /> that the device can detect a leak of 3 gallons per hour at 10 psi. Leak detector monitored line volumes <br /> shall be appropriate for the make and model of the installed leak detectors, and shall be verified at the <br /> time of installation. <br /> ❑ Monitoring system functionality after first fuel delivery: Functionality of the monitoring system must be <br /> verified ("all functions normal" must be verified) in operating condition to ensure it meets the <br /> requirements of Title 23 California Code of Regulations and the Health & Safety Code (functionality of <br /> vacuum sensors and vacuum zones communication, etc.), demonstration of automatic shut-downs, if <br /> applicable. <br /> 7. The installed UST system must be compliant with all applicable laws, regulations, and industry standards. <br /> 8. Anchor all USTs using tank anchors as detailed in the permit application and per manufacturer's written <br /> install instructions. <br /> 9. Install concrete of sufficient thickness over USTs, around sumps and dispensers, according to the <br /> manufacturer's written installation instructions and buoyancy calculations. <br /> 10. Install all product and vent piping according to manufacturer's written installation instructions; maintain all <br /> appropriate piping distances and installation depths. <br /> 11. All appropriate test ports must be installed to facilitate routine communication testing (e.g. at the beginning <br /> and end of each vacuum zone branch, and inside sumps, etc.). No additional shut off valves should be <br /> installed between the monitored interstitial spaces and their respective sensors. <br /> 12. All monitoring systems shall be listed in the State Water Resources Control Board's Local Guidance Letter <br /> (LG) 113 letter. <br /> 13. All installation and testing shall be in compliance with manufacturer's instructions, section 2635 and section <br /> 2636 of California Code of Regulations (CCR). <br /> 14. All tank top openings that are connected to the primary space of the UST must have secondary <br /> containment, audible/visual alarm and be vapor tight or terminate at grade. <br /> 15. Sumps and under dispenser containment must be constructed in a manner to prevent vapors from entering <br /> the backfill. <br /> 16. All secondary containment must be constructed to prevent water intrusion. <br /> 17. The secondary containment system must be continuously monitored as required under California Health <br /> &Safety Code (HSC) 25290.1 <br /> 18. Overfill prevention shall satisfy CCR 2635(c)(1) pursuant to the permit application, all appropriate drop <br /> tube and tank gauge design calculations shall be provided to the EHD prior to scheduling of the overfill <br /> verification inspection. <br /> 19. No ball floats shall be installed on vent lines to comply with the overfill prevention requirements (40 C.F.R. <br /> §280.20(c)) <br /> 20. All metal components in direct contact with the ground such as flexible connectors, swing joints, fittings, <br /> clamps, bands, and pumps shall have adequate corrosion protection. <br /> 3 of 4 <br />
