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 N/A This section must be completed if LLDs are installed. Was a leak simulated to verify LLD performance? ® ❑ ❑ (Check all that apply.) Simulated leak rate verified : ® 3 GPH ❑ 0. 1 GPH ❑ 0 . 2 GPH Was the test apparatus properly calibrated? ® ❑ ❑ For emergency generator tank systems, does the LLD create an audible and visual alarm when a leak is detected ? ❑ ❑ N 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? N ❑ ❑ For electronic LLDs, does the turbine automatically shut off if any portion of the monitoring system is disabled or N ❑ ❑ disconnected ? For electronic LLDs, does the turbine automatically shut off if any portion of the monitoring system malfunctions or fails a ® ❑ ❑ test? 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 ? N ❑ ❑ Were all LLDs confirmed operational within regulatory requirements? N ❑ ❑ For any answer of "N" above, describe in Section Xlll how and when these issues were or will be corrected. XIII .
