MEMORANDUM <br />ENGINEERING CORP. <br />TO: ICasey Foley, RENS <br />Interim Director, San Joaquin Environmental Health Department <br />FROM: Norman Hantzsche, PE, Questa Engineering Corporati <br />r <br />DATE: November 22, 2019 <br />SUBJECT: Final - OWTS Design Review for Navu Farms, Inc., 7300 West Delta Ave, Tracy <br />In my design review memorandum of November 13, 2019, I noted that the OWTS design for the <br />subject project proposed a 5 -ft groundwater separation below the disposal field rather than 84t, <br />as required by San Joaquin County OWTS regulations (Table 1.10.2). The response letter of <br />November 20, 2019 from the designer (Don Chesney), argued against imposing the 8 -ft <br />separation standard on the basis that: (a) the clay loam soil conditions provide suitable texture <br />and biological activity for treatment of bacteria and viruses and (b) due to the very small volume <br />of wastewater discharge and oversized leachfield, there will be more than adequate time and <br />space for soil absorption and treatment. <br />I agree with the above rationale presented by the designer and believe it satisfies the footnote <br />exception to the County percolation -groundwater separation criterion (Table 1.10.2) which <br />allows for an alternative separation distance if "...mitigated by the system design or <br />enhancement". <br />1 <br />Box 70356, 1220 Brickyard Cove Rd. Suite 206 Pt. Richmond, CA 94807 T.• 510(236.6114 F.• 510236.2423 E: Questa�QuestaEC.com <br />
