GE <br /> GENESIS ENGINEERING 8 REDEVELOPMENT <br /> 1.0 INTRODUCTION <br /> This Site Characterization Work Plan("Work Plan")was prepared by Genesis Engineering & <br /> Redevelopment, LLC ("GE&R") on behalf of Randy Thomas to identify potential <br /> environmental impacts to the property located at 2303 West Lane in Stockton, California <br /> ("Site"). The Work Plan contains descriptions of the tasks associated with a preliminary <br /> assessment of potential volatile organic compound and hydrocarbon impacts to shallow <br /> groundwater that may have resulted from past and current activities by the Site tenant, R&L <br /> Diesel Services. <br /> 1.1 Site Setting <br /> The Site is currently used for parts storage and vehicle repair and maintenance (including <br /> tearing down, cleaning, re-building, and otherwise maintaining and servicing heavy diesel <br /> equipment). On-site facilities include a parts warehouse, a vehicle maintenance building, and <br /> a dynamometer. South of the maintenance area is a septic system and drain field. Hazardous <br /> materials are reportedly stored in the vehicle maintenance building. <br /> The Site location is bounded on the south by Klinger Road,to the west by the Union Pacific <br /> Railroad, to the north by commercial activities, and to the east by West Lane, as shown on <br /> Figure 1. A layout of the Site is shown on Figure 2. <br /> The Site vicinity is reportedly underlain by alluvial deposits consisting of clay, silt, and sand. <br /> Groundwater flow direction in the general vicinity of the Site is variable. At a property <br /> located approximately 1/3 mile north of the Site (American Forest Products, 2801 West <br /> Lane,) shallow groundwater is reported to flow north-northeast. Groundwater in the vicinity <br /> of the Site has been encountered at depths of approximately 46 to 48 feet below grade. <br /> 2.0 SCOPE OF WORK <br /> This Work Plan was developed to assess whether impacts to shallow groundwater may have <br /> occurred at the Site as a result of past or current on-site activities. The Work Plan is focused <br /> on shallow groundwater down-gradient (northeast) of current on-site activities, soil near the <br /> site septic system, and soil beneath the on-site hazardous material storage area. <br /> Reconnaissance groundwater samples will be collected from two locations: <br /> 1. One soil/reconnaissance groundwater boring(designated B-1)will be placed <br /> down-gradient (northeast) of the dynamometer; and <br /> 2303 West Lane 1 of 11 <br /> Site Investigation Work Plan <br /> May 2009 <br />
