UNDERGROUND STORAGE TANK MONITORING SYSTEM CERTIFICATION FORM (Page 5 of 6) XII . LINE LEAK DETECTOR TESTING ❑ Check this box if line leak detectors (LLD) are NOT installed . (Do not complete this section.) Y N NA This section must be completed if LLDs are installed. Was a leak simulated to verify LLD performance? N ❑ ❑ Check all that apply.) Simulated leak rate verified : N 3 GPH ❑ 0 . 1 GPH ❑ 0 .2 GPH Was the testing apparatus properly calibrated? N ❑ ❑ For emergency generator tank systems, does the LLD create an audible and visual alarm when a leak is detected ? ❑ ❑ N For mechanical LLDs, does the LLD restrict the flow through the pipe when a leak is detected? N ❑ ❑ For electronic LLDs , does the turbine automatically shut off when a leak is detected ? N ❑ ❑ For electronic LLDs , does the turbine automatically shut off if any portion of the monitoring system is disabled or disconnected ? N ❑ ❑ For electronic LLDs, does the turbine automatically shut off if any portion of the monitoring system malfunctions or fails a test? N ❑ ❑ For electronic LLDs, have all accessible wiring connections been visually inspected for kinks and breaks? N ❑ ❑ Were all items on the equipment manufacturer's maintenance checklist completed? ® ❑ ❑ Were all LLDs confirmed operational within regulatory requirements? N ❑ ❑ For any answer of "N" above, describe in section Xlll how and when these issues were or will be corrected. XI11 . COMMENTS XIV. VACUUM / PRESSURE/ HYDROSTATIC MONITORING EQUIPMENT TESTING ❑ Check this box if VPH monitoring is NOT used . (Do not complete this section.)
