i <br /> n C <br /> rate for a shallow test 's Tess than or equal to 60 minutes per inch (minlin) drop. A deep <br /> percolation test hole has a depth greater than 3.5 up to 25 feet;. a satisfactory <br /> percolation rate for a deep test is 30 min/in or less. For the Site to utilize a standard <br /> septic system, one percolation test must demonstrate a satisfactory percolation rate <br /> within the proposed septic system disposal field_ <br /> Only a shallow percolation test was required. Details and results of the percolation test <br /> are summarized in the following table. <br /> Table 2.

A satisfactory <br /> -percolation rate for a"deep"test is less than or equal to 30 minutes per inch. <br /> Discussion of Percolation Test Results <br /> The soils within the sewage disposal areas of the Site have demonstrated a satisfactory <br /> percolation rate for the use of a standard septic system in accordance with the <br /> requirements of the San Joaquin County Environmental Health Department. <br /> Discussion of Septic System Sizing <br /> Septic system construction utilizing leach tines and pits should follow the San Joaquin <br /> County On-Site Wastewater Disposal Standards (2003) where applicable. <br /> LOG E0915 -- •----- Page 7 <br />
