Jr FFThis RODUCTION AND PROJECT DESCRIPTION and Subsurface Contamination Report(SSCR) contains the results of my findings forated on the Highway 99 Frontage Road near the north end of Stockton, California. This report was prepared for the exclusive use by Mr. Guru Arora, 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 and/or Leaking Underground Fuel Tanks (LUFTs), septic systems and septic tanks, agrichemical applications and electrical transformers. No chemical analysis was conducted for this investigation, nor was there an inspection of the on-site residential building 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 "information or other record information from government agencies may be obtained directly from appropriate government agencies or from commercial services." The property subdivision for residential purposes is illustrated on the attached Tentative Parcel Map. �,2) The subject Parcel composing this project and assessed for this report, has been outlined on the San Joaquin County Parcel Viewer Map. The project description is as follows: To divide 7.88 acres into U•sJ four Parcels. Each Parcel is to be 1.97 acres. Stormwater drainage is on-site and the property is in Zone B (outside the 100-year floodplain). 2 Chesney Consulting
