Diamond Pet Food Processors of Ripon,LLC June 30,2011 <br /> Report of Waste Discharge Page 6 of 17 <br /> TREATMENT, STORAGE,AND DISPOSAL METHODS(§21740(A)(2)) <br /> Treatment of the wastewater will consist solely of aeration. All discharges will be retained on-site, in <br /> ponds or dispersed to irrigated fields. No off-site discharge is planned. <br /> WASTE MANAGEMENT UNIT CHARACTERISTICS (§21750) <br /> TOPOGRAPHY(§21750(D)) <br /> The Site is relatively flat and level, with local topographic variations associated with the series of <br /> ponds and ditches. In general, the site slopes gently to the south (toward the Stanislaus River),with a <br /> steep slope at the southern edge of the site adjacent to the river. The northern part of the Site is <br /> within the 500-year flood plain, and the southern edge along the Stanislaus River is within the 100- <br /> year floodplain, based on the Federal Emergency Management Agency's (FEMA)Flood Insurance <br /> Rate Map, Community-Panel Number 06077CO801F. <br /> CLIMATOLOGY(§21750(E)) <br /> The property is in the Eastern San Joaquin Hydrologic Area(No. 5-22.01), as depicted on <br /> interagency hydrologic maps prepared by the Department of Water Resources (DWR) in August <br /> 1986. The mean annual rainfall is approximately 12 inches (at Modesto, California Data Exchange <br /> Center data) and the 10-year 24-hour storm is 2.76 inches (also Modesto). The reference <br /> evapotranspiration rate is approximately 51 inches per year(at Modesto, California Irrigation <br /> Management Information System data). <br /> GEOLOGY(§21750(F)) <br /> MAP AND CROSS SECTIONS <br /> Figure 6 shows a geologic map of the Site and vicinity. Figures 7 through 9 show cross sections <br /> through the Diamond site, based on geophysical logs of site monitoring wells. <br /> REGIONAL HYDROGEOLOGIC SETTING <br /> Geology and hydrogeology of the site and vicinity has been described in detail in previous reports.2 <br /> Briefly,the site is underlain by a sequence of Tertiary and Quaternary continental deposits (Tulare <br /> Formation). These deposits consist of interbedded sands/gravels and silts/clays or mixtures thereof. <br /> 2 Lawrence&Associates,May 5, 1992,Impacts on Receiving Waters from Discharge at the Simpson Paper Company <br /> Facility,Ripon, California. <br /> 010107.00, Task I Lawrence&Associates <br /> w:Iclientsl diamond pet foods1010107.00-ripon rowdldiamondpet_rowdjune2011_draft.docx <br />
