Main Street <br /> Stockton, CA 95202 <br /> Subject: Quarterly Inspection and Sampling of MicroSepTec System at Carmelo Business <br /> Park, Tracy, California <br /> Dear Mr. Huggins: <br /> A quarterly inspection of the MicroSepTec system installed at the Carmelo Business Park was <br /> conducted on July 28, 2008. The system was operating normally and no repairs were required. <br /> The meter reading for the effluent discharge was 1920550. Attached are the results of the <br /> laboratory analysis for nitrate. Based on the laboratory results the calculation of the nitrogen in <br /> the effluent is as follows: 14162 x 1 = .23 mg/L nitrogen as nitrate. Since this meets the design <br /> criteria of the system no further analysis or investigation was conducted. <br /> Since the last inspection, repair of the flowmeter was required due to a clog in the screen. <br /> Concurrent with the repair of the flowmeter the lift stations between the east and west building <br /> and at the south-east corner of the east building were pumped of sludge. The first chamber of the <br /> MicroSepTec system was also pumped to remove sludge accumulation. <br /> If you have any question please contact me at the number listed below. <br /> Sincerely, <br /> 2 <br /> H.
