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? 0 ❑ El (Check all that apply.) Simulated leak rate verified : [g3 GPH F10 . 1 GPH ❑ 0.2 GPH Was the testing apparatus properly calibrated ? z ElEl emergency generator tank systems , does the LLD create an audible and visual alarm when a leak is detected ? ElElN For mechanical LLDs , does the LLD restrict the flow through the pipe when a leak is detected ? ❑ 1 ❑ 0 For electronic LLDs, does the turbine automatically shut off when a leak is detected ? ❑X ❑ ❑ For electronic LLDs , does the turbine automatically shut off if any portion of the monitoring system is disabled or disconnected? ❑X ❑ ❑ For electronic LLDs , does the turbine automatically shut off if any portion of the monitoring system malfunctions or fails a test? ❑X ❑ ❑ For electronic LLDs , have all accessible wiring connections been visually inspected for kinks and breaks ? QX ❑ ❑ Were all items on the equipment manufacturer's maintenance checklist completed ? 0 ❑ ❑ Were all LLDs confirmed operational within regulatory requirements? Q ❑ ❑ For any answer of "M' above, describe in Section Xlll how and when these issues were or will be corrected. XIII . COMMENTS XIV.
