HWY 120, Ripon <br />APN: 24506029/30, SR0084280 <br />Environmental Health Department <br />Jasjit Kang, REHS, Director <br />Muniappa Naidu, REHS, Assistant Director <br />PROGRAM COORDINATORS <br />Robert McClellon, REHS <br />Jeff Carruesco, REHS, RDI <br />Willy Ng, REHS <br />Melissa Nissim, REHS <br />Steven Shih, REHS <br />The San Joaquin County Environmental Health Department (EHD) has reviewed the Soil Suitability/Nitrate <br />Loading Study (SSNL) dated September 23, 2021 for the above noted location and has the following <br />comments for your consideration. <br />The SSNL was prepared to determine the suitability of the above noted parcel for onsite wastewater treatment <br />system (OWTS) usage and the potential long-term nitrate loading impact to groundwater from the proposed <br />commercial OWTS. <br />Based on the information provided the EHD can make the following findings: <br />a. The SSNL supports the suitability for standard OWTS usage and a standard OWTS may be installed <br />for the proposed development pursuant to San Joaquin County Ordinance Code Title 9, Section 9- <br />1105.2(d). <br />Note: A standard septic system for this project requires a minimum tank capacity of 6,750 gallons & <br />5, 220 square feet area for the filter bed. <br />b. Alternatively, the OWTS may be installed according to the engineered/alternative OWTS plans and <br />recommendations found in this study. If the owner chooses the engineered/alternative OWTS design: <br />obtain a Commercial Alternative/Engineered Designed System Permit and install the OWTS based on <br />the designs and recommendations of the engineer. The OWTS must pass inspection before final <br />approval of the OWTS permit. <br />c. Audible and visual alarms are required if a lift station is installed. Testing of the audible and visual <br />alarm are required before final approval of the OWTS permit (SJC OWTS 10.5). <br />d. Open, pump, and backfill any septic tank to be abandoned on the site under permit and inspection by <br />the Environmental Health Department (San Joaquin County Development Title, Section 9-1110.3 & 9- <br />1110.4). <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 />�tevenHS <br />Program Coordinator <br />CC: Chesney Consulting <br />P.O.
