Geosyntec° <br /> consultants <br /> 4.1.3 Permitting and Access <br /> Prior to drilling, all of the necessary permits will be obtained from the San Joaquin <br /> County Environmental Health Department (SJEHD). Required permits will include <br /> boring (well) permits for the installation of all exploratory borings and groundwater <br /> wells. <br /> In addition, encroachment permits will be obtained from the City of Stockton for the <br /> locations proposed to be installed in the public right-of-ways. For the locations <br /> proposed on private property, access agreements will be negotiated between LCERT <br /> and the private property owners. <br /> 4.1.4 Pre-Field Meeting <br /> A pre-field meeting will be conducted in the field between staff and the field <br /> subcontractors prior to initiating the field activities for each work day. During the <br /> meeting, staff will confirm the work to be performed, identify potential hazards to the <br /> field staff, describe the health and safety measures that will be implemented, and the <br /> anticipated project schedule. <br /> 4.2 INVESTIGATION ACTIVITIES <br /> The Sampling Matrix is presented on Table 2 and includes a summary of samples to be <br /> collected and analytical methods for each proposed sample location. Field activities are <br /> to be conducted under the supervision of a California Professional Geologist or <br /> Professional Engineer to provide direction and oversight of the field activities and to <br /> ensure that the field activities follow appropriate quality control and applicable <br /> regulatory guidelines. If additional sampling activities are deemed necessary beyond <br /> the scope of work proposed herein, they will be conducted in accordance with the <br /> methods and procedures described this Work Plan. <br /> 4.2.1 Soil Borings <br /> Ten (10) boreholes will be installed utilizing sonic drilling techniques to facilitate the <br /> collection of depth discrete soil and hydropunch groundwater samples at the locations <br /> shown on Figures 3, 4, and 5. Sonic drilling technology utilizes telescopic casing <br /> advancement to isolate the desired sampling interval to reduce the risk of vertical cross- <br /> contamination during installation and sampling activities. Additionally, sonic allows <br /> for the collection of a continuous core of the boring. <br /> Pre-Design Investigation Work Plan 16 18.05.12 <br />
