3.0 OBJECTIVE The objective of this assessment is to conduct an environmental site investigation to evaluate current site conditions. 3.1 SCOPE OF WORK In order to achieve the objective, the following scope of work will be performed under the guidance of the site-specific Health and Safety Plan, included as Appendix A of this workplan. 3.1.1 Pre-Fieldwork Activities Prior to initiating field activities,necessary permits will be obtained from the San Joaquin County Environmental Health Department(EHD). A workplan, master file record information form (MFR), site mitigation fees, and a well permit application will be submitted to EHD prior to conducting drilling activities. Upon completion of the environmental assessment, soil and groundwater results must be submitted to the EHD for review. Exceedances of non-petroleum hydrocarbon standards will need to be reported to the State of California Regional Water Quality Control Board (RWQCB). The RWQCB will review the data and then provide their recommendations for future actions. Additionally, Underground Service Alert subscribing companies will be notified and a utility locator will be employed to confirm locations of underground utilities. 3.1.2 Soil Characterization A subsurface investigation will be conducted in order to characterize the current environmental conditions at the site. ERM will subcontract a drilling company to complete the following activities. Four soil borings will be drilled to determine current soil conditions and to evaluate groundwater characteristics. The soil borings will be drilled to approximately 15 feet bgs or the first encountered groundwater to evaluate soil and groundwater conditions and to collect samples to assist in evaluating soil characteristics. The borings will be advanced using a direct-push method on a truck-mounted GeoProbe®unit. Additionally, ERM 3 LESCO,INC/0024301A0-12/21/04
