Mr.`Fred Cruz, SJVAPCD August I9,2004 <br /> Authority to Construct an SVE System � <br /> j" USA 65,Lodi,California <br /> Page 2 <br /> f ' <br /> Soil Vapor Extraction and Abatement <br /> Petroleum hydrocarbon vapors will be extracted from extraction wells S-1, S-2, and <br /> MW-8 (see Figure 2) using a 5 hp Roots positive displacement blower package rated at <br /> 100 cfm @ 14" Hg. The extracted soil vapors will be abated in the electric catalytic <br /> j oxidizer prior to discharge to the atmosphere. Figure 3 illustrates the process flow <br /> f diagram for the SVE system.;Equipment specifications for the proposed SVE system are <br /> presented in Appendix B and pertinent equipment specifications are listed below: l <br /> i • 'Stack height: 13 feet', <br /> + Stack inner diameter: 6 inches (circular) <br /> h <br /> + Stack temperature: 600° 800'F <br /> • BIower capacity: 100 cfm <br /> i <br /> '• Distance to the nearest building: approximately 150 feet LL 4 <br /> 10 Distance to nearest residential building: 500 feet _ <br /> • Distance to nearest school: 1;056 feet (www.yahoo.com) <br /> SVE System Start up and Operation <br /> C <br /> Stratus proposes to conduct system start-up and source testing programs for the proposed <br /> SVE remediation system during the first 2 days of system operation. The following <br /> parameters will be monitored and recorded on field data sheets during the system start up: <br /> } <br /> • Vapor extraction rate, <br /> + Applied vacuum at each vapor extraction well., <br /> • Influent flow in to the system, and <br /> • PID measurements for organic vapors from the extraction wells. <br /> During the source testing, one set of.influent and effluent air samples will be collected <br /> and forwarded to a state-certified laboratory for analysis. The air samples will be <br /> analyzed on a 24-hour turnaround basis for total petroleum hydrocarbons as Gasoline <br /> (TPHG) by United States Environmental Protection Agency (USEPA) Method 8015, and <br /> for benzene, toluene, ethylbenzene, and total xylenes (BTEX), and methyl tertiary butyl <br /> ether.(MTBE) by USEPA Method 8260. Analytical results will be used to calculate the <br /> destruction efficiency of the system. Manufacturer's literature states that the destruction <br /> efficiency for the system for petroleum hydrocarbons is 98 percent. <br /> k <br /> P:1USA Gasoline10065�CorrespondencelUSA 65 ATC For New Unit1USA 65 ATC for new Unit.doc <br /> J <br />
