2.0 SCOPE OF WORK The objectives of this proposed scope of work are to further define the extent of soil contamination and to determine if groundwater is impacted beneath the site. To achieve these objectives, soil and groundwater samples will be collected for laboratory analysis from three soil borings. 2. 1 Planningand permitting I 9 I The project planning task will include the preparation of a health and safety plan , acquisition of required permits , advance notification of all field activities, and a routine underground utility survey. Prior to initiating fieldwork, a site-specific health and safety plan will be prepared according to 29 CFR 1910 . 120. The health and safetyIan will include safety procedures for work p y p to be performed , chemical hazard information , site safety officers, and a medical emergency location . To perform the proposed scope of work, a drilling permit will be obtained from PHS/EHD. Since two of the soil borings will be drilled in the city sidewalk, an encroachment permit will be obtained from the city of Stockton . At least two working days prior to field work , PHS/EHD will be notified so that any inspections can be scheduled . Underground Service Alert will also be notified to mark any underground utilities . 2.2 Soil and Groundwater Sampling and Analysis To evaluate the distribution and extent of gasoline hydrocarbons in subsurface soil , and to determine if groundwater has been impacted by the failure of the former UST system , soil and groundwater samples will be collected for analysis from three locations. As indicated on Figure 2 , one soil boring will be drilled at the south end of each former UST, and one soil boring will be located adjacent to the former dispenser island inside the garage building . These are the locations , which previously exhibited with the highest concentrations of gasoline hydrocarbons in soil . 2 . 2 . 1 Soil and Groundwater Sampling Soil and groundwater-grab samples will be collected using a Geoprobe® Direct-Push Technology rig (Geoprobe) . Each of the three soil borings will be advanced to the groundwater table, expected at a depth of approximately 35 feet. 6
