Limited Phase II Site Assessment Work Plan <br />BOTTINI PROPERTY <br />1500 Madruga Road, Lathrop, California <br />1.0. INTRODUCTION <br />AdvancedGeo, Inc. (AGI) has prepared this Limited Phase 11 Site Assessment Work Plan <br />for the property located at 1500 Madruga Road, Lathrop, California (site). The scope of <br />work includes the advancement of seven (7) soil borings for the collection of soil, soil - <br />vapor and groundwater samples, and preparation of a report. <br />This work plan has been prepared as required by the San Joaquin County Environmental <br />Health Department (EHD) application for drilling permit. A plan of the site with proposed <br />soil boring locations is presented in Figure 1. <br />2.0 SCOPE OF WORK <br />During performance of a Phase I Environmental Site Assessment, AGI identified several <br />areas of potential environmental concern including a wash rack, a paint booth and a diesel <br />above -ground storage tank and dispensing area. Based on these findings, a preliminary <br />investigation is being conducted at the site to determine if historical site usage has <br />impacted the subsurface. The following tasks include: <br />• Permitting and pre -field work activities. <br />• A total of two (2) soil borings (131, 62) will be advanced 10 to 15 feet below surface <br />grade (bsg) near the wash rack area for collection of soil and grab groundwater <br />samples <br />• A total of three soil borings (133, B4 and 135) will be advanced near the diesel fueling <br />area. Two of the borings will be advanced to a depth of 5 feet bsg for collection of <br />soil samples. A third boring will be advanced 10 to 15 feet bsg for collection of soil <br />and grab groundwater samples. <br />• A total of two (2) soil borings (136 and 137) will be advanced to a total depth of 5 <br />feet bsg near the paint booth area for collection of soil -vapor samples. <br />• A report of findings will be prepared documenting the results of the investigation. <br />Each of these tasks are described in greater detail below. <br />2.1. PERMITTING AND PRE -FIELD WORK ACTIVITIES <br />Applicable site assessment drilling permits will be obtained from the EHD. Also, a site- <br />specific Health and Safety Plan will be prepared. Prior to mobilization, each soil probe <br />boring location will be clearly marked, and a utility clearance obtained through <br />
