LOCKEFORD ST., LODI, <br /> CALIFORNIA <br /> Dear Mr. Kemena: <br /> Per the requirements of the SJCAPCD Permit to Operate a soil vapor extraction system at the <br /> above-referenced site, Science & Engineering Analysis Corporation (SEACOR) is submitting the { <br /> enclosed information detailing the system operating parameters and influent/effluent sample results <br /> through November 1992. Based on an effluent vapor concentration of 30 ppmv measured on <br /> November 12, 1992, a total VOC emission rate of 0.95 pounds per day (lbs/day) was calculated. <br /> Emission calculations for November 1992 are attached. Based on the above emission rate, the i <br /> system continues to operate within permit limits. Also, please find attached a copy of the analytical <br /> laboratory report for the influent sample collected on November 12, 1992. <br /> Based on our conversation with you on November 17, 1992, we understand that the two GAC <br /> canisters can now be taken off-line, removed, and disposed of under proper manifest. Therefore, <br /> we have scheduled their removal for November 23, 1992. <br /> If you have any questions, please do not hesitate to contact us at (415) $52-1545. <br /> Sincerely yours, <br /> Science & Engineering Analysis Corporation <br /> �r <br /> Gordon G.
