UNDERGROUND STORAGE TANK MONITORING SYSTEM CERTIFICATION FORM 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? EI ❑ ❑ Check all that apply,) Simulated leak rate verified : (] 3 GPH ❑ 0 . 1 GPH ❑ 0 .2 GPH Was the testing apparatus properly calibrated? [i] ❑ ❑ For emergency generator tank systems , does the LLD create an audible and visual alarm when a leak is detected? ❑ ❑ For mechanical LLDs , does the LLD restrict the flow through the pipe when a leak is detected? H1 ❑ ❑ For electronic LLDs , does the turbine automatically shut off when a leak is detected ? ❑ ❑ (] For electronic LLDs , does the turbine automatically shut off if any portion of the monitoring system is disabled or disconnected? ❑ ❑ I] For electronic LLDs , does the turbine automatically shut off if any portion of the monitoring system malfunctions or fails a test? ❑ ❑ 0 For electronic LLDs , have all accessible wiring connections been visually inspected for kinks and breaks? ❑ ❑ (] Were all items on the equipment manufacturer's maintenance checklist completed ? ❑ ❑ Were all LLDs confirmed operational within regulatory requirements? El ❑ ❑ For any answer of "N" above, describe in section Xlll how and when these issues were or will be corrected. XIII . COMMENTS XIV.
