UNDERGROUND 'STORAGE TANK <br /> MONITORING SYSTEM CERTIFICATION' FORM (Page', 5 of 6) <br /> XVI. LINE LEAK DETECTOR TESTING <br /> I� 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 r <br /> Check all that applyj apply. Simulated leak rate verified : 3 GPG f� 1 . 1 GPG r 0 . 2 GPH <br /> Was the testing apparatus properly calibrated ? ry r r <br /> For emergency generator tank systems , does the LLD create an audible and visual alarm when a leak is detected? r r I✓ <br /> For mechanical LLDs , does the LLD restrict the flow through the pipe when a leak is detected ? <br /> For electronic LLDs , does the turbine automatically shut off when a leak is detected ? I✓ r r <br /> For electronic LLDs, does the turbine automatically shut off if any portion of the monitoring system is disabled or disconnected ? <br /> For electronic LLDs , does the turbine automatically shut off if any portion of the monitoring system malfunctions or fails a test? Iv 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 ? h r r <br /> Were all LLDs confirmed operational within regulatory requirements? w <br /> For any answer of "N" above, describe in section X111 how and when these issues were or will be corrected. <br /> XIII.
