LOCKEFORD ST., LODI, f <br /> CALIFORNIA <br /> Dear Mr. Chan: <br /> �Nz <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 September 1992. Based on an effluent vapor concentration of 50 ppmv measured on l f ` <br /> September 15, 1992, a total VOC emission rate of 1.3 pounds per day (lbs/day) was calculated. <br /> i h} <br /> Emission calculations for September 1992 are attached. Based on the above emission rate, the <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 September 15, 1992. ` <br /> If you have any questions, please do not hesitate to contact us at (415) 296-7877. i- <br /> i <br /> Sincerely yours, ; <br /> Science & Engineering Analysis Corporation <br /> Gordon G.
