1. (a) Release detection equipment must be tested in accordance with manufacturer's instructions upon installation and at least once every 12 months for proper operating condition, programming, and calibration by a service technician meeting the requirements of section 2633. Testing of continuous vacuum, pressure, or hydrostatic interstitial release detection systems for piping must include verification of continuity to the extent practical as approved by the Unified Program Agency.
2. (b) Service technicians testing release detection equipment must affix a tag/sticker in a readily visible location on each release detection equipment component that is being tested. The tag/sticker must include the date the underground storage tank component was tested and the service technician's International Code Council identification number.
3. (c) Testing of systems that utilize an impact shear valve to stop the flow of hazardous substance at the dispenser as part of the under-dispenser containment monitoring must verify proper function of mechanical release detection equipment and the impact shear valve to confirm that hazardous substance will not dispense when the impact shear valve is closed. If the impact shear valve does not completely shut off dispensing, or if a system of this type fails to function properly at any time, the valve and any other non-functional under-dispenser containment release detection equipment must be replaced in accordance with section 2652(a)(1)(B) prior to resuming dispensing from the dispenser monitored by the inoperable equipment.
4. (d) Testing of line leak detectors that perform monitoring in accordance with section 2652(a)(3) as required by the facility's monitoring program must be done by simulating a release equivalent to 0.1 gallon per hour defined at 150 percent of the normal operating pressure.
5. (e) The results of the release detection equipment test must be recorded on the “Release Detection Equipment Testing Report Form” located in appendix 5.
