3 of 4 Environmental Health Department INSPECTIONS PRIOR TO FINAL APPROVAL p) Verification of accurate vacuum zone programming, including monitored volumes. q) Leak detector test, after first fuel delivery: Verify the device can detect a leak of 3 gallons per hour at 10 psi. Verify line volumes are appropriate for the make and model of the installed leak detectors. r) Monitoring system functionality, after first fuel delivery: Functionality of the monitoring system, must be verified to ensure it meets the requirements of CCR Title 23 and HSC Chapter 6.7. 7. The UST system must be installed in compliance with all of the following: a. The installed UST system must be compliant with all applicable laws, regulations, and industry standards. All installation and testing shall be in compliance with manufacturer’s instructions and CCR 2635 and 2636. All monitoring system components shall be listed in the State Water Resources Control Board’s Local Guidance Letter (LG) 113. b. All tank pre-installation tests shall be performed according to tank manufacturer instructions. c. All primary containment including any integral secondary containment system must be certified by an independent testing organization and labeled as required by the organization (CCR 2631(b); UL, ULC, ANSI, API, ASTM, etc. See CCR 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. d. 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, per CCR 2631(d). e. All metal components in direct contact with the ground, such as flexible connectors, swing joints, fittings, clamps, bands, and pumps, shall have adequate corrosion protection. f. Install concrete of sufficient thickness over USTs and around sumps and dispensers, according to the manufacturer’s written installation instructions and approved buoyancy calculations. g. All tank top openings that are connected to the primary space of the UST must have secondary containment, audible/visual alarm, and be vapor tight or terminate at grade. h. Sumps, including UDCs, must be constructed in a manner to prevent vapors from entering the backfill. i. All secondary containment must be constructed to prevent water intrusion and must be continuously monitored as required under HSC 25290.1. j. All vacuum zone volumes must be accurately programmed and their volumes adequate for their respective vacuum sensors. Chase piping must be VPH monitored and included in its respective product piping vacuum monitoring zone. All sensors must be installed to detect a leak at the earliest opportunity. k. Overfill prevention shall satisfy CCR 2635(c)(1), pursuant to the permit application. No flow restrictors (ball floats) shall be installed on vent lines, to comply with overfill prevention requirements (Code of Federal Regulations, Title 40, section 280.20(c)) l. All installed UST components must be compatible with the materials being stored (including biodiesel and E85). m. Hazardous material or waste cannot be released, intentionally or unintentionally, to the sewer/septic system, storm water system, or any other waters of the state. If a release occurs, it will be considered illegal hazardous waste disposal and will be subject to enforcement. n. No additional shut off valves should be installed between the monitored interstitial spaces and their respective sensors.
