l <br /> 2.0 SCOPE OF WORK <br /> The objectives of thisro osed scope of work are to further define the <br /> p p p extent of soil contamination <br /> and to determine if groundwater is impacted beneath the site. To achieve these objectives, soil and <br /> groundwater samples will be collected for laboratory analysis from three on-site soil borings. <br /> I 2.1 Planning and Permitting <br /> The project planning task will include the preparation of a health and safety plan, acquisition of <br /> required permits, advance notification of all field activities, and a routine underground utility survey. <br /> Prior to initiating fieldwork, a site-specific health and safety plan will be prepared according to 29 <br /> CFR 1910.120. The health and safety plan will include safety procedures for work to be performed, <br /> chemical hazard information, site safety officers, and a medical emergency location. <br /> 1 � .. <br /> l <br /> To perform the proposed scope of work, a drilling permit will k e obtained from PHS/EHD. Since all <br /> of the drilling will be conducted on the subject site, neither encroachment permits nor private <br /> property access agreements will be required. <br /> At least two working days prior to field work, PHS/EHD will be notified so that any inspections can <br /> be scheduled. Underground Service Alert will also be notified to mark any underground utilities. <br /> i . <br /> 2.2 Soil and Groundwater Sampling and Analysis <br /> 1 <br /> To evaluate the distribution and extent of gasoline hydrocarbons in subsurface soil, and to <br /> determine if groundwater has been impacted by the failure of the former UST system, soil and <br />{.. groundwater samples will be collected for analysis from three`locations. As indicated on Figure 2, <br /> one soil boring will be drilled at each end of the former UST, and one soil boring will be located <br /> adjacent to the former underground piping run near P1. These are the locations, which previously <br /> exhibited concentrations of gasoline hydrocarbons in soil. <br /> 2.2.1 Soil and Groundwater Samplinq <br /> Soil and groundwater-grab samples will be collected using a Geoprobe® Direct-Push Technology <br /> rig (Geoprobe). Each of the three soil borings will be advanced to the groundwater table, expected <br /> at a depth of approximately 25 feet below the subgrade. <br /> r <br /> 5 <br />
