Box 3794 <br />Turlock, CA 95381 <br />RE: Soil Suitability/Nitrate Loading Study <br />17239 Louise Road, Escalon <br />APN: 20321016, SR0084773 <br />The San Joaquin County Environmental Health Department (EHD) has reviewed the Soil Suitability/Nitrate <br />Loading Study (SSNL) dated 12 January 2022 and the SSNL Addendum dated February 27, 2022 for the <br />above noted location and 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 nitrate loading impact to groundwater from the proposed <br />OVVTS. <br />Based on the information provided the EHD can make the following findings: <br />Based on the information provided the EHD finds that the SSNL Study supports the suitability for <br />standard OVVTS usage for the proposed development pursuant to San Joaquin County Ordinance <br />Code Title 9, Section 9-1105.2(d). <br />The OVVTS design proposed in this study may be an acceptable alternative to a standard OVVTS, <br />provided that the system is installed and maintained according to the engineers design and <br />recommendations found in this study. Obtain an Alternative/Engineered OVVTS permit if owner <br />chooses to install the OVVTS proposed in this study (OVVTS Standards 2.2). <br />The OVVTS permit must provide a plot plan that demonstrates applicable setbacks in table 1.5 are met <br />or exceeded, specifically the setback from the new OVVTS to the public well onsite (OVVTS Standard <br />2.2). <br />Percolation test conducted on 17 December 2021 yields shallow percolation rates of 35.7 min./inch, <br />27.8 min./inch, & a deep percolation rate of 17.9 min./inch. At this rate an 8' soil separation is required <br />between bottom of dispersal field and the groundwater. Groundwater is reported at 70 feet below <br />surface. (San Joaquin County OVVTS Standard Table 1.10.2). <br />If you have any questions please contact Aaron Gooderham, Registered Environmental Health Specialist, <br />REHS, at agooderham@sjgov.org or (209) 616-3062. <br />4Z_ <br />Steven Shih, REHS <br />Program Coordinator <br />CC: COSTA, DANIEL R & SHIRLEY A <br />1269 SPRING CREEK DR <br />RIPON, CA 95366 <br />1868 E.
