1 <br /> Mr. Tom Busenbark, S.NAPCD November 30, 2004 <br /> Source Test Report Project No. 2007-0065-01 <br /> USA 65, Lodi, California <br /> Page 2 <br /> During the system source test, the following parameters were monitored and recorded on <br /> field data sheets (Appendix A): <br /> • Influent flow rate (field flow), <br /> • System influent flow rate (after dilution), <br /> • Applied vacuum on the vapor extraction wells, <br /> • Influent and effluent air temperature, and <br /> • Photo-ionization detector (PID) measurements for organic vapors from the <br /> extraction wells. <br /> Influent and effluent air samples were collected on October 20, 2004, in the presence of <br /> SJVAPCD personnel. Samples were collected in one-liter tedlar bags from sample ports <br /> (influent, system-influent, and effluent; Figure 3) using a tedlar bag vacuum chamber and <br /> an air-sampling pump. Samples were forwarded to Alpha Analytical, Inc. (Alpha), a <br /> state certified laboratory (FLAP #2019), and analyzed for total petroleum hydrocarbons <br /> as gasoline (TPHG) using United States Environmental Protection Agency (USEPA) <br /> method SW8015B/DHS LUFT Manual, and for benzene, toluene, ethylbenzene, and total <br /> xylenes (BTEX compounds), and methyl tertiary butyl ether (MTBE) using USEPA <br /> Method SW8260B (Appendix B). <br /> Analytical results of soil vapor samples collected on October 20, 2004, were used to <br /> calculate mass extraction rates, mass emission rates, and destruction efficiencies. Table 1 <br /> presents a summary of the system operating parameters, analytical results, and <br /> destruction efficiencies. Detailed calculations for estimated mass emission rates and <br /> destruction efficiencies are presented in Appendix C. <br /> Based on analytical results of air samples collected on October 20, 2004, TPHG, <br /> benzene, and MTBE were extracted at the rate of approximately 64.42 pounds per day <br /> (lbs/day), 0.053 lbs/day, and less than 0.038 lbs/day, respectively. The mass emission <br /> rates for TPHG, benzene, and MTBE were calculated to be less than 0.009 lbs/day, less <br /> than 0.0005 lbs/day, and less than 0.0005 lbs/day, respectively: The destruction <br /> efficiency of the SVE system for TPHG was estimated to be approximately 100 percent <br /> for samples collected on October 20, 2004. <br /> The results of the source test demonstrate compliance with the conditions listed in the <br /> ATC. Considering compliance of the SVE system with ATC requirements, Stratus <br /> requests that a permit to operate be issued. During the continuous operation of the SVE <br /> system, Stratus will continue to collect influent and effluent air samples monthly, and <br /> KAUSA Gasoline100651Reports\USA 65_Source Test Rept_Nov 04.doc <br />
