September 10, 2004 <br /> NOA Project Number: E040104A <br /> r <br /> 6.7 Discussion of Percolation Test Results <br /> The soils within the sewage disposal areas of Parcels 1 through 5 have demonstrated a <br /> satisfactory percolation rate in accordance with the requirements of the EHD. The soils of <br /> these parcels appear to be suitable for a septic system utilizing shallow leach lines and seepage <br /> pits. The soils of Parcel,6 did not demons ra a satisfactory percolation rate in the area tested; <br /> a septic system placed in this area will need to be engineered. <br /> 6.8 Discussion of Septic System Sizing <br /> Septic System Construction should follow the San Joaquin County On-Site Wastewater <br /> Disposal Standards where applicable. Refer to the attached Nitrate Loading Study for a <br /> complete discussion of the necessary recommendations. <br /> ,. 7.0 CONCLUSIONS <br /> 7.1 Signatures <br /> r <br /> The signatures of the environmental professionals involved in the preparation of this report <br /> can be found at the front of this package. <br /> r <br /> 8.0 SELECTED REFERENCES <br /> Arnaudo, Greg, Personal Communication, August 25 and September 1, 2004. <br /> Crites, R., Tchobanoglous, G., 1998, Small and decentralized wastewater management <br /> systems: McGraw-Hill series in water resources and environmental engineering, <br /> McGraw-Hill Boston first edition. <br /> Hantzshe N., Finnemore, E.J. 1992, Predicating Ground-Water Nitrate-Nitrogen Impacts. <br /> Ground Water, Vol. 30, No. 4. <br /> San Joaquin Community Development Department, 2004, www.co.san-joaquin.ca.us. <br /> San Joaquin County Environmental Health Department, 2003, On-Site Wastewater Disposal <br /> Standards: San Joaquin County Environmental Health Department, 304 E.
