Secondary Containment Emergency Vent: <br /> The weighted emergency vent for the secondary compartment is a Morrison Bros, UL Listed <br /> weighted vent for Flammable and Combustible Liquids Tank Accessory and has a vent capacity <br /> of 503,517 SCFH (Standard Cubic Feet per Hour) and is sized equal to the vent capacity of the <br /> largest emergency vent (recommended by Morrison Brothers). The vent was observed to have <br /> been recently replaced. At the time of inspection, the weighted emergency vent for the <br /> secondary interstitial space of the tank was exercised and lifted as expected. <br /> Veeder-Root <br /> The fueling system is monitored by a VEEDED-ROOT TLS-300C which monitors and calculates <br /> the following items: <br /> • Fuel volume in both tanks. <br /> 0 Ullage in both tanks. <br /> • 90% ullage in both tanks. <br /> • Height of fuel in both tanks. <br /> • Water volume in both tanks. <br /> • Water level in both tanks. <br /> • Temperature inside both tanks. <br /> • Presence of liquid in the interstitial space. <br /> 0 Presense of liquid in the secondary piping for the product lines going through the levy. <br /> At the time of inspection on 11/5/2020, the VEEDER-ROOT system alarm was tested. All <br /> functions were observed to have tested as normal. No Alarm or Warning lights were observed <br /> to be flashing before or after the alarm /system was tested. The sensor located in the <br /> interstitial space was removed and observed to be clear of liquid prior to the test. The sensor <br /> was replaced and the system tested. <br /> 3.3. Recommended Actions for Continued Fuel Storage Tank Use <br /> 3.3.1. Ensure the interstitial space is clear of water at all times to prevent internal <br /> corrosion from forming. This will increase the life of the tank. <br /> 3.3.2. Contact your petroleum contractor about adding secondary containment to the <br /> product lines running under the dock to the two gasoline dispensers. Currently <br /> the secondary containment ends at the levy where the product lines transition to <br /> rubber hoses to allow for the dock to move up and down with the water level. <br /> 3.3.3. Contact your petroleum contractor about adding under dispenser containment <br /> pans below the two fuel dispensers. Currently the sheer valves and all internal <br /> dispenser components are directly over the water. <br /> 3.3.4. Contact your petroleum contractor to discuss adding clock gauges on both fuel <br /> tanks and an outside audible/visual alarm to alert the fuel hauler on the level of <br /> the tanks while filling. <br /> 3.3.5. Test the sensors in the secondary containment for the piping running through the <br /> levy. <br /> eFUEL, LLC 8 <br />
