As you are <br /> aware, we plan to remediate the source area with soil vapor extraction (SVE) combined with air <br /> sparging technology, and treat the offsite 1,2 DCA plume with ozone sparging technology. Mr. <br /> Dave Jenkins with Kleinfelder completed a Source Test in your presence on May 19, 2003 <br /> during which you inspected the system as well as our monitoring and sampling procedures. This <br /> report details that testing. We have prepared this Source Test Report in accordance with <br /> SJVAPCD's "Application For Authority to Construct (ATC) and Permit to Operate (PTO) <br /> Instructions." <br /> SOURCE TEST RESULTS <br /> For background, the extraction and emission control system used at the site is a Stealth Industries <br /> Cobra 500 thermal oxidizer capable of 500 scfm of air. For the Source Test we ran the unit at a <br /> flow of approximately 250 sefm. The unit performed the extraction with a 15 HP positive <br /> displacement blower. The burner for the unit was supplemented with natural gas and is rated at a <br /> maximum of 1,000,000 BTU/hr. A blower running at 250 cfm supplied combustion air to the <br /> burner. The exhaust stack height of the treatment system is 6'6" feet and the diameter of the <br /> stack is 22 inches. The minimum combustion chamber temperature and stack gas temperature is <br /> 1400 degrees F. <br /> During operation of the Source Test, several parameters were monitored and the inlet and outlet <br /> of the system were sampled (laboratory data sheets and chain of custody record). A summary of <br /> the findings are provided in Table 1: <br /> 12280.REM2/STOC3R881 Page I to 4 <br /> Copyright 2003,Kleinfelder,Inc.
