Von Sosten Rd <br /> APN 209-380-52, SR0081818 <br /> The San Joaquin County Environmental Health Department (EHD) has reviewed the Soil Suitability/Nitrate <br /> Loading (SSNL) Study, dated February 27, 2010 and its addendum dated March 11, 2019 for the above noted <br /> location, and has the following comments for your consideration. <br /> The SSNL Study was prepared to determine the suitability of the above noted parcel for onsite wastewater <br /> treatment system (OWTS) usage and the potential impact of nitrate to groundwater for the proposed project <br /> development. The proposed development project includes: <br /> 1. An existing three-bedroom house and the proposed two-bedroom second unit dwelling with the OWTS <br /> total usage of 350 gallons per day. <br /> Based on the information provided, the EHD can make the following findings. <br /> 1. The SSNL Study supports the suitability for standard OWTS usage for the proposed development <br /> project on the above mentioned parcel, pursuant to San Joaquin County Ordinance Code Title 9, <br /> Section 9-1105.2(d), provided proposed OWTS and 100% replacement area can meet all required <br /> minimum setbacks from any water wells. <br /> 2. The data indicates the onsite water well has elevated level of nitrate and may not be a suitable source <br /> for the potable water supply for new development.A potable water supply that can provide a consistent <br /> source of safe and clean water adequate for human consumption, cooking, and sanitary purposes for <br /> the proposed new home needs to be established prior to the issuance of building permits (2016 CA <br /> Plumbing Code, Section 601.2). <br /> Any deviation to project development or OWTS usage other than mentioned above shall require new Soil <br /> Suitability/Nitrate Loading Study. <br /> If you have any questions please contact Naseem Ahmed, Registered Environmental Health Specialist, <br /> REHS, at (209) 468-3436 or nahmed@sjgov.org. <br /> Michael Kith, REHS <br /> Program Coordinator <br /> c: Live Oak GeoEnviron mental <br /> 1868 E.
