Task 1: Prepare a Health and Safety Plan As required by federal regulation, a Health and Safety Plan (HSP) addressing the specific health and safety issues for field work at the Site will be prepared. The HSP will be reviewed by Levine•Fricke personnel and subcontractors before work at the Site begins. Task 2: Obtain Permits and Utility Clearances Monitoring well construction permits will be obtained, as required, from the San Joaquin County Public Health Services Department for the drilling and installation of the proposed monitoring wells. For budgetary purposes, as discussed in Task 4, we have assumed that three ground-water monitoring wells will be installed at the Site. Locations of underground utilities at the Site (e.g., underground pipelines, etc.) will be identified by potholing and probing each drilling location to depths of approximately 5 feet bgs. For the purposes of this work plan, it is assumed that SFPP will contract directly with the potholing subcontractor. Task 3: Drill and Install Three Shallow Ground-Water Monitoring Wells Three shallow ground-water monitoring wells are proposed for drilling and installation at the Site. The wells will be drilled to depths of approximately 25 feet bgs. The locations of the proposed wells are shown on Figure 1. The soil borings for each monitoring well will be drilled using the hollow-stem auger drilling method with 10-inch outside diameter augers. Due to the close proximity of existing monitoring well MW-1, soil samples will be collected during drilling from drill cuttings for lithologic description at minimum 2.5-foot intervals. Each proposed well will be constructed of 4-inch-diameter polyvinyl chloride (t VC) well casing. The perforated interval will be selected to sample ground water from the more permeable shallow sediments. After the well casing has been placed in the completed borehole, the well annulus opposite the perforated interval will be backfilled with an appropriately sized sand pack material to approximately 1 or 2 feet above the perforations. Bentonite pellets will be emplaced above the sand pack to isolate the perforated interval from material above and prevent the entrance of grout into the sand pack. A cement-bentonite grout will then be placed above the bentonite seal to the ground surface, sealing the remainder of the borehole interval from surface water. A weather-proof, tamper-proof, flush-mounted traffic vault or locking aboveground monument will then be cemented in place. All drilling equipment and sampling tools will be steam cleaned before each use. 2
