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? rEl ❑ El Check all that apply.) Simulated leak rate verified : I] 3 GPH El 0 . 1 GPH ❑ 0 .2 GPH Was the testing apparatus properly calibrated? El El 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 ? ❑ For electronic LLDs , does the turbine automatically shut off when a leak is detected ? ❑ ❑ E For electronic LLDs , does the turbine automatically shut off if any portion of the monitoring system is disabled or disconnected? rEl ❑ I] For electronic LLDs , does the turbine automatically shut off if any portion of the monitoring system malfunctions or fails a test? El [i]For electronic LLDs , have all accessible wiring connections been visually inspected for kinks and breaks? El2 Were all items on the equipment manufacturer's maintenance checklist completed ? ElElWere all LLDs confirmed operational within regulatory requirements? ❑ ❑ For any answer of "N" above, describe in section Xlll how and when these issues were or will be corrected. X111 .
