UNDERGROUND STORAGE TANK <br /> MONITORING SYSTEM CERTIFICATION FORM (Page 5 of 6) <br /> XVI. LINE LEAK DETECTOR TESTING <br /> r Check this box if line leak detectors (LLD) are NOT installed. (Do not complete this section.) Y N NA <br /> This section must be completed if LLDs are installed. <br /> Was a leak simulated to verify LLD performance? I✓ r F <br /> Check all that apply.) Simulated leak rate verified: Fv1- 3 GPH r 1.1 GPH r 0.2 GPH <br /> Was the testing apparatus properly calibrated? r r r <br /> For emergency generator tank systems, does the LLD create an audible and visual alarm when a leak is detected? r r r <br /> For mechanical LLDs, does the LLD restrict the flow through the pipe when a leak is detected? r r r <br /> For electronic LLDs, does the turbine automatically shut off when a leak is detected? F70 r r <br /> For electronic LLDs,does the turbine automatically shut off if any portion of the monitoring system is disabled or disconnected? I✓ r r <br /> For electronic LLDs,does the turbine automatically shut off if any portion of the monitoring system malfunctions or fails a test? 140 r r <br /> For electronic LLDs, have all accessible wiring connections been visually inspected for kinks and breaks? r r r <br /> Were all items on the equipment manufacturer's maintenance checklist completed? r r r <br /> Were all LLDs confirmed operational within regulatory requirements? r r r <br /> For any answer of"N"above, describe in section Xlll how and when these issues were or will be corrected. <br /> XIII.
