Fine Rd., Linden <br />APN 093-040-760, SR0083706 <br />The San Joaquin County Environmental Health Department (EHD) has reviewed the Soil Suitability/Nitrate <br />Loading (SSNL) Study, dated May 6, 2021 and submitted on May 12, 2021 for the above noted location, and <br />has the following comments for your consideration. <br />The SSNL was prepared to determine the suitability of the above noted parcel for onsite wastewater treatment <br />system (OVVTS) usage and the potential long-term impact of nitrate to groundwater for the following proposed <br />project. <br />Three-bedroom Residential Accessory Dwelling. <br />Based on the information provided, the EHD can make the following findings: <br />1. The SSNL Study supports the (OVVTS) usage with the following conditions: <br />According to the SSNL, the estimated nitrate loading from existing and proposed OVVTS usage is <br />13.2 mg/L as nitrate-nitrogen and the maximum contaminant level allowed is 10 mg/L-N. The <br />SSNL also states that nitrate-nitrogen observed in the domestic water well sample were at a <br />concentration of 0.92 mg/L. The SSNL goes on to say that groundwater is approximately 165 to <br />175 feet below the ground surface at the site. With all of these factors taken into consideration, <br />EHD will require an oversized 2,000-gallon septic tank for installation of a standard Onsite <br />Wastewater Treatment System. <br />The OVVTS and its 100% replacement areas shall meet all required minimum setbacks stated in <br />San Joaquin County (OVVTS) Standard and Well Standard. <br />If you have any questions please contact Michael Suszycki, Registered Environmental Health Specialist, at <br />msuszycki@sjgov.org or (209) 598-7001. <br />Steven Shih, REHS <br />Program Coordinator <br />c: Petralogix Engineering Inc. 26675 Bruella Rd., Galt, CA. 95632 <br />1868 E.
