Diamond Pet Food Processors of Ripon,LLC June 30,2011 <br /> Report of Waste Discharge Page 14 of 17 <br /> remain out of compliance, although showing improving quality. The net mass of TDS to the <br /> semiperched aquifer would be almost 10 times less than the levels imparted from the operation of the <br /> previous paper mill plus cogen(about 900 lbs/day vs. the previous 8,000 lbs/day). <br /> ENGINEERING AND CHEMICAL PROPERTIES <br /> The surface soil across the project site is a sandy silt that should be suitable for foundations and <br /> embankments if properly developed against the potential for compressibility and liquefaction. The <br /> underlying soils include sands, gravel, and clays. Historically, the soils have supported extensive <br /> structures and the existing water-related facilities without adverse effects. There is no evidence that <br /> the site soils cannot continue to support such activities without adverse effects. <br /> STABILITY ANALYSIS AND FAULT IDENTIFICATION <br /> According to California Division of Mines and Geology (CDMG)Note 43: "A maximum probable <br /> earthquake is the maximum earthquake that is likely to occur during a 100-year interval. It is to be <br /> regarded as a probable occurrence, not as an assured event that will occur at a specific time." <br /> Maximum probable earthquakes are calculated for faults having displacement during Holocene (less <br /> than 10,000 years old) time. There are no mapped or observed active,potentially active, or inactive <br /> faults beneath the property. According to the Seismic Shaking Hazard Map of California14, the peak <br /> ground acceleration (10%probability of being exceeded in 50 years) is 0.2 g. The site is within <br /> California Seismic Zone 3. <br /> LAND AND WATER USE(§21750(H)) <br /> Land use within one mile of the project site, includes industrial/commercial immediately to the north <br /> and west, riparian land immediately south (along the Stanislaus River), and residential and <br /> agricultural uses beyond that. <br /> Domestic water in Ripon is supplied by the City of Ripon, from surface and groundwater; Figure 2 <br /> shows the locations of the nearest City of Ripon production wells. <br /> 14 Peterson,M.,et. al, 1999,Seismic Shaking Hazard Maps of California,California Division of Mines and Geology,Map <br /> Sheet 48. <br /> 010107.00, Task I Lawrence&Associates <br /> w:Iclientsl diamond pet foods1010107.00-ripon rowdldiamondpet_rowdjune2011_draft.docx <br />
