A brief start-up history is also <br /> provided. <br /> BACKGROUND <br /> The SVE system has been provided by Condor Earth Technologies, Inc. (Condor). The SVE system was <br /> manufactured by Solleco Inc ., and is operated in conjunction with two 1000-pound carbon filters for <br /> ground water treatment and disposal to the sanitary sewer system. The SVE system was installed at the <br /> site in September 2004. The SVE system was connected to the existing SVE wells previously installed <br /> and operated under APCD, ATC #N3039-0-0, N- 174-2-0, and N- 174-2-1 . <br /> STARTUP SAMPLING AND INSPECTION <br /> The initial inspection was held September 30, 2004. Photo Ionization Detector (PID) readings were 135 .6 <br /> parts per million (ppm) (by volume) for both influent and effluent. The system was shut down and <br /> repairs were made. A VOC destruction efficiency of 95 % could not be demonstrated and the SVE system <br /> did not pass initial inspection and the samples were not analyzed. A verbal authorization to collect a <br /> second set of samples was obtained by phone on October 7, 2004. A second inspection was conducted on <br /> October 7, 2004. Actual fall time operation of the equipment was initiated on October 7, 2004. PID <br /> readings were 163 .5 ppm for the influent and 1 ppm for the effluent. A VOC destruction efficiency of <br /> 95% was demonstrated with. the PID that will be used with this equipment. During the inspection, two <br /> air samples were collected for analysis. The samples were collected and analyzed as discussed below. <br /> The laboratory report sheets are attached to this submittal. <br />
