I. INTRODUCTION AND PROJECT DESCRIPTION This Surface and Subsurface Contamination Report (SSCR) contains the results of my findings for property located on Jack Tone Road northeast of Stockton, California. This report was prepared exclusively for Mr. & Mrs. Raymond and Elsie Camera, and the San Joaquin County Environmental Health Department (EHD). The purpose of this study was to investigate and identify real or potential surface and subsurface contamination existing within the entire subject property and report the findings to the Client and the Environmental Health Department. According to the San Joaquin County Development Title, a Surface and Subsurface Contamination Report is required at the time of Tentative Map submittal. The San Joaquin County Development Title, Section 9-905.12 (a) states "A Surface and Subsurface Contamination Report shall identify any potential sources of surface and subsurface contamination caused by past or current land uses." The report shall include evaluation of nonpoint sources of hazardous materials including agricultural chemical residues and nitrate concentrations in the underlying groundwater. Potential point sources include fuel tanks, discarded items, septic systems, agrichemical applications and electrical transformers. No chemical analysis was conducted for this investigation, nor was there an inspection and testing of the on-site buildings for asbestos containing materials (ACMs). Interpretation of County Ordinance Section 9-905.12 (a) has been to focus on the subject property exclusively, unless it is documented or observed that an environmental concern in proximity to the subject property could potentially affect said property. This Surface and Subsurface Contamination approaches,but does not completely encompass the requirements of a Phase I Environmental Site Assessment (ESA) as promulgated by the American Society of Testing and Materials (ASTM E-1527-00). The Environmental Health Department recognizes that the Surface and Subsurface Contamination Report is not intended to completely fulfill the requirements of the Phase I ESA. The Department does however, maintain that certain components of the Phase I ESA must be applicable to the SSCR, as follows: Section 7.1.7 of the ASTM Document states under"Sources of Standard Source Information,"that LLTEngineers. rmation or other record information from government agencies may be obtained directly from priate government agencies or from commercial services." roperty subdivision and subsequent Tentative Map is being prepared by the firm of Wong, The project description is as follows: To divide 221.68 acres into three Parcels. The subject Parcels composing this project and assessed for this report,have been outlined on the oaquin County Parcel Viewer Map and the attached A.P.N. Map. There is no proposal to build tructures on the subject Parcels in the future since it is being subdivided for family purposes. Page -2- Chesney Consulting
