Based on the information furnished to JPCA, JPCA proposed a site <br /> l characterization workplan for drilling three soil borings, <br /> collecting soil samples, commencing at five feet below grade to. <br /> 50 feet, unless the saturated zone, i.e. groundwater, was <br /> encountered prior to 50 feet. If groundwater was encountered at <br /> 50 feet or less, 3 Monitoring wells, extending 10 feet into the <br /> aquifer would be constructed. The proposed workplan, with a Site <br /> Specific Safety Plan, was submitted to Jay McIlrath with a copy <br /> to San Joaquin County Environmental Health Division (SJCEHD) . <br /> Soil samples, checked using a Photoionization Detector (PID) <br /> {PHOTOVAC MODEL #20201 for hydrocarbon vapors, reading above <br /> background and groundwater samples were to be analyzed for Total <br /> Petroleum Hydrocarbons as Gasoline (TPHG) , Benzene, Toluene, <br /> Ethylbenzene and Xylene (BTEX) , as well as oxygenates. <br /> The workplan was approved by SJCEHD with the following additional <br /> work required. A boring permit was to be secured from SJCEHD. <br /> Sample should be analyzed for Total Petroleum Hydrocarbons as <br /> Diesel (TPHD) Work was to be completed by October 22, 1999. <br /> Bore holes below 50 feet may be required as site conditions may <br /> dictate drilling below 50 feet. SJCEHD was to be notified 48 <br /> hours prior to any work. <br /> US Alert was contacted and the area for drilling marked for their <br /> reconnaissance. The area marked for drilling was clear of <br /> subterranean utilities. <br /> JPCA applied for and paid for a drilling/well construction <br /> permit. A copy is included in Appendix A <br /> Forty-eight hours prior to the commencement of work on the <br /> subject property, SJCEHD was contacted as required. The PID was <br /> checked and tested for accuracy on the evening of September 7, <br /> 1999 . <br /> FIELD WORK <br /> On the morning of September 8 and again on September 9, 1999, <br /> John N. Alt and John P. Cummings met with the drilling crew at <br /> the parcel located at 4975 East Main Street, Stockton, CA. Mr. <br /> McIlrath and Carol Oz, Sr. REHS from SJCEHD were also on site. <br /> The Site Specific Health and Safety Plan was read and signed by <br /> the drilling crew prior to commencement of the drilling <br /> operations. Carol Oz, SJCEHD inspector, met us and also read and <br /> signed the Site Specific Health and Safety Plan. <br /> SOILS EXPLORATION SERVICES INC. was the driller for the borings <br /> and well construction. The Boring Logs were prepared by the <br /> 2 <br />
