3.0 SOIL VAPOR EXTRACTION SYSTEM OPERATION <br /> On June 2, 1999, ENSR started the thermal oxidizer soil vapor extraction (SVE) system in the <br /> presence of an inspector from the San Joaquin Valley Unified Air Pollution Control District <br /> (SJVUAPCD) <br /> According to ENSR, five extraction wells (VW-1 D, VW-1 S, VW-2S, VW-3 and VW-4) were utilized <br /> by the system, during startup The system parameters at startup included a flow rate of 214 <br /> standard cubic feet per minute (scfm), vacuum of 65 inches of water column, and a concentration <br /> of volatile organic compounds by Flame Ionization (FID) of 2,100 parts per million by volume <br /> (ppmv) <br /> During startup, ENSR collected vapor samples for analysis to monitor the efficiency of the SVE <br /> system The system influent soil vapor sample contained 4,960 milligrams per cubic meter (mg/m) <br /> of purgeable hydrocarbons, 109 Mg/M3 of benzene, 650 mg/m3 of toluene, 148 mg/m3 of <br /> ethylbenzene, and 560 mg/m3 of xylenes This translated to an initial mass recovery rate of 123 5 <br /> pounds per day Between startup on June 2, 1999 and the last system monitoring on April 13, <br /> 2000, a total mass of 7,001 5 pounds of hydrocarbons had been removed <br /> During the second quarter of 2000, ENSR monitored the system on April 13, 2000 The unit was <br /> shut down from February 15 through April 13, 2000 to assess rebound conditions According to <br /> ENSR, the SVE system has reached a point of limited continued effectiveness ENSR's SVE <br /> System Operation Summary Memorandum is included as Appendix B <br /> l� 6 <br />
