SOW <br /> CI. INTRODUCTION AND PROJECT DESCRIPTION <br /> This Surface and Subsurface Contamination Report(SSCR) contains the results of our findings for <br /> property owned by Ms. Sue Lindly Ohlendorf on Linne Road near Tracy, California. This report <br /> was prepared exclusively for Ms. Ohlendorf,her Attorney Mr. Jose Alva, and the San Joaquin <br /> County Environmental Health Department (EHD). The purpose of this report was to investigate <br /> and identify real or potential surface and subsurface contamination existing within the entire <br /> subject property and report the findings to the Client and the Environmental Health Department. <br /> According to the San Joaquin County Development Title, a Surface and Subsurface Contamination <br /> Report is required at the time of Tentative Map submittal. The San Joaquin County Development <br /> Title, Section 9-905.12 (a) states "A Surface and Subsurface Contamination Report shall identify <br /> any potential sources of surface and subsurface contamination caused by past or current land uses." <br /> This report complies with the San Joaquin County Development Title for a "Surface and <br /> Subsurface Contamination Report." The report shall include evaluation of nonpoint sources of <br /> hazardous materials including agricultural chemical residues and high concentrations of nitrate in <br /> the groundwater. Potential point sources include aboveground and underground storage tanks <br /> (ASTs/USTs), leaking underground storage tanks (LUSTS), septic systems, chemical storage areas <br /> and electrical transformers. No chemical analysis was conducted for this investigation, nor was <br /> there an inspection of any on-site or surrounding buildings for asbestos containing materials <br /> (ACMs). <br /> Interpretation of County Ordinance Section 9-905.12 (a) has been to focus on the subject property <br /> exclusively, unless it is documented or observed that an environmental concern in proximity to the <br /> subject property could potentially affect the property. <br /> (�t0 <br /> The property subdivision is illustrated on the attached Assessor's Parcel Map. The subject parcels <br /> composing this project and assessed for this report, have been outlined on the Parcel Map. Five <br /> contiguous parcels make up the property. The subdivision will reoeiva water from Cnnnty Sarvic, <br /> (( �4 Area(CSA-44) wells, and wastewater treatment ilia]ao proposed to be under CSA-44 by a central <br /> wastewater treatment plant, The wastewater treatment plant is to be located in the southwest <br /> 1 corner of Bates Road and Chrisman Road. Stormwater drainage management will be by a <br /> community retention basin. <br /> This Surface and Subsurface Contamination is close to, but does not completely encompass the <br /> requirements of a Phase I Environmental Site Assessment(ESA)as promulgated by the American <br /> Society of Testing and Materials (ASTM E-1527-00). The Environmental Health Department <br /> recognizes that the Surface and Subsurface Contamination Report is not intended to completely fulfill <br /> LLSeetion <br /> ents of the Phase I ESA. The Department does however, maintain that certain <br /> of the Phase I ESA as promulgated by ASTM must be applicable to the SSCR, as follows: <br /> of the ASTM Document states under "Sources of Standard Source Information," that <br /> 2 <br /> Chesney Consul ing <br />
