In conjunction with EMCON's on-site investigation. ARCO has requested that EMCON <br /> perform an off-site environmental investigation at nearby properties. <br /> This letter is our second request regarding authorization for EMCON and its subcontractors to drill <br /> one boring and install one vapor extraction well on your property, Parcel No. 57 of the San Joaquin <br /> County Assessor's map, page 43 of Book 140; the parcel is at the intersection of Cherokee Lane and <br /> Lodi Avenue, California, which is west of ARCO service station no. 760. <br /> It is EMCON's understanding from the city of Lodi Public Works Department that the alley located <br /> north of your property has been divided among adjacent property owners. That is, your property now <br /> extends to 10 feet from the limits of your previous property boundary to the alley. The environmental <br /> investigation EMCON proposes to conduct on your property will provide data on the condition of soil <br /> northwest of the ARCO station and comply with San Joaquin County Public Health Services <br /> requirements that hydrocarbons in soil be delineated. <br /> Enclosed are ARCO's License Agreement and three figures. Figure 1 is a generalized site plan showing <br /> features near ARCO service station no. 760. Shown on Figure 1 is the approximate location of the <br /> vapor extraction well EMCON proposes to install on your property. Figure 2 is a schematic well <br /> design showing the construction of a typical vapor extraction well installed by EMCON for projects <br /> throughout California. <br /> The vapor extraction well will be drilled using a truck-mounted drill rig with 8- to 10-inch-diameter <br /> augers. A 4-inch-diameter polyvinyl chloride casing will be installed in the boring. For safety and <br /> security reasons, the top of the casing will be fitted with a locking cap and an aluminum cover with <br /> specially designed fasteners. The aluminum cover will be set approximately.25 inch above surrounding <br /> grade. The boring will take approximately 3 hours to drill. and the vapor extraction well construction <br /> will take approximately 4 hours. EMCON anticipates that the work will be completed in approximately <br /> 1 day. Two subcontractor personnel will operate the drib rig, and a geologist from EMCON will be <br /> SA('/PJ0\0805\08051420.2BM-94 PAS:1 <br />
