At the time of inspection significant corrosion was observed on the sides and underside of the <br /> tank. In several areas pitting was observed to be forming as well. See the required and <br /> recommended actions below in regard to the corrosion and pitting noted on the tank. <br /> 3.2. Piping and Ancillary Features <br /> 4.000 gallon —Regular Gasoline Compartment <br /> Pump <br /> The pump on the 4,000 gallon compartment was observed to be a 1.5 Horse Power submersible <br /> pump manufactured by Red Jacket Pumps for use with Class 1 Group D locations that is <br /> compatible and UL listed for use with gasoline. Consult your petroleum contractor prior to <br /> placing an alternative fuels into the tank to ensure tank and system compatibility. According to <br /> Red Jacket Pumps, the pump has a standard VR ready check valve. <br /> Piping <br /> The pipe going from the fill box to the tank is single walled 3" threaded pipe and has an inline <br /> 3" manual shut off valve and a 3" Morrison Brothers one-way Check Valve installed <br /> downstream from the fill box on the product fill line. In addition, there is a 3" vapor return line <br /> at ground level. <br /> The 2" single walled threaded steel product line runs 125' from the top mounted red jacket <br /> pump to the dock where the dispensers are mounted. The 2" piping enters into sealed and <br /> monitored 4" Fiberglass secondary containment pipe just before the 2" pipeline runs below <br /> surface through the berm. On the dock side of the berm the single walled product line exits the <br /> 4" fiberglass secondary containment pipe and converts to an approximately 10' long flexible <br /> rubber hose submerged in the water to allow the dock to rise and drop with the water level. <br /> The product line transitions back to 2" single walled threaded pipe and continues under the <br /> dock to the dispensers. <br /> Manual shut off valves were observed in the following locations along the pipeline from the <br /> tank to the dispensers: <br /> 1. On top of the tank. <br /> 2. At the transition prior to entering into the 4" Fiberglass Secondary Containment. <br /> 3. At the transition exiting the 4" Fiberglass Secondary Containment when the product <br /> line converts to a rubber hose. <br /> 4. At the transition on the end of the dock when the rubber hose transitions back to 2" <br /> steel threaded pipe. <br /> The 2" single walled threaded product pipeline was observed to have coating failure on the <br /> underside of the piping going from the tank across the grass toward the building. <br /> eFUEL, LLC 5 <br />
