• 3.0 REVISED WORK PLAN <br />' The objectives of the proposed scope of work are to further define the lateral n f impacted soil <br /> � p p p extent o p <br />' and groundwater, and to define the vertical extent of impacted groundwater beneath the former <br /> UST To achieve these ob_iectives, three soil borings will be drilled to first groundwater and one <br /> cone penetration test soil boring will be drilled to a deeper groundwater-bearing interval for soil <br /> and/or groundwater r sampling <br /> 3.1 Project Planning and Permitting <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 /> To perform the proposed scope of work, drilling permits will be obtained from EHD Since all of the <br /> drilling will be conducted on-site, neither off-site access agreements nor encroachment permits will <br /> be required At least two working days prior to field work, Ramage Environmental will notify EHD <br /> and Underground Service Alert so that regulatory and utility inspections can be scheduled <br /> 32 Three Soil Borings to First Groundwater ! �, <br />' To further assess the lateral extent of impacted soil and groundwater, soil and groordwater <br /> samples will be collected from three on-site soil borings drilled to first groundwat ,The proposed <br />' soil borings will be located in the southwest corner of the sub-grade parking area in the southeast <br /> corner of the street grade asphalt parking area, and in the sub-grade parking area approximately <br /> feet north of monitoring well MW-1 These proposed boring locations are shown on Figure 3 <br />' A C-57 licensed drillingcontractor will drill the soil borings with 8-inch diameter hollow-stem augers <br /> 9 <br />' The proposed soil borings will be drilled to further evaluate a silty sand interval previously- <br /> encountered at approximately 30 to 35 feet below street grade Since the sub-grade parking area <br /> is approximately 11 feet below street grade, the soil borings proposed for the sub-grade parking <br /> area should only be drilled to a depth of approximately 25 feet The ultimate depths of the soil <br /> borings will depend on a fithologic and hydrogeologic conditions observed during drilling <br /> 9 <br />
