BOX 3794 <br /> Turlock, CA 95381 <br /> RE: Nitrate Loading Study for 11878 Clover Rd., Tracy <br /> Service Request SR0077931 <br /> The San Joaquin County Environmental Health Department (EHD) has received and reviewed <br /> your Nitrate Loading study report dated July 13, 2017, and has found it meets the requirements <br /> of San Joaquin County and Code Title 9, section 9-1105.2 (d). <br /> SPECIAL COMMENTS: <br /> The results of the Nitrate Loading Study indicate the proposed Onsite Wastewater Treatment <br /> System (OWTS) has the potential to impact groundwater above the maximum contaminant <br /> level of 10 mg/L. The report proposes an Alternative/Engineer Designed OWTS as a means to <br /> mitigate this groundwater quality impact. <br /> In order to monitor the effectiveness of the proposed mitigation and pursuant to San Joaquin <br /> County OWTS Standards, Section 2.10, an annual permit and sampling of the onsite water <br /> well by a certified laboratory for Nitrate as Nitrogen is required. The analytical results of the <br /> sampling must be transmitted from the certified laboratory to the EHD by December 31st of <br /> each year. The annual permit fee for an Alternative OWTS with sampling only (no inspection <br /> activity) is $152. <br /> If you have any questions please call Rodney Estrada, REHS Program Coordinator, at (209) <br /> 468-0331. <br /> Rodney Estrada, REHS <br /> Program Coordinator <br /> 1868 E.
