1 <br /> Soil vapor will be extracted from two sets of horizontal soil vapor extraction pipes (0 2 <br /> inch slotted, 4-inch diameter polyvinyl chloride [PVC] pipes, one located at 10 feet below <br /> ground surface [bgs] and the other 17 feet bgs), and two groundwater monitoring wells <br /> (MW-3 and MW-4), which will be manifolded together and connected to the intake side <br /> of the vacuum blower Pneumatic pumps will be used to extract groundwater from four <br /> groundwater monitoring wells (MW-1, MW-2, MW-3, and MW-4) See Figure 2 <br /> The pneumatic pumps will pump groundwater through the heat exchanger to preheat the <br /> water, then through the spay aerator to volatilize the petroleum hydrocarbons The <br /> vacuum pump is used to both extract soil vapors from the vadose zone and remove the <br /> petroleum hydrocarbon laden air from the spray aerator These vapors are then combusted <br /> in the ICE The exhaust from the ICE passes through two automotive-type catalytic <br /> convertors placed in series, before discharge to the atmosphere through a 5-foot-high, 2 5- <br /> inch-diameter, exhaust stack <br /> Expected Emission of Air Contaminants See Appendix F <br /> Operating Schedule 52 weeks per year, 7 days per week, 24 hrs per day <br /> Process Weight See Appendix F <br /> Fuel Liquified petroleum gas (LPG) <br /> Source 1000-gallon tank <br /> Heating content 16 8 BTU per pound at 60° F <br /> Consumption rate 1 1 gallons per hour <br /> Process and Instrumentation Flow Diagram See Appendix E <br /> Equipment Drawings See Appendix E <br />
