The application process includes preparation and submittal <br /> of this Workplan, a Safety P/an, permit application forms, Licensed Contractors Declaration forms, <br /> and a Master File Record form. <br /> Exploratory Drilling and Sub-Surface Sampling <br /> We plan the advancement of one boring for groundwater sampling and five borings for soil gas <br /> sampling at spatially distributed locations on the property (see attached Site Map). One boring <br /> will be performed near the western property boundary and the remaining five borings will be <br /> performed along the northern, western, and southern sides of the onsite building. The borings <br /> will be performed with a truck-mounted direct push (Geoprobe) rig. Five of the borings will <br /> extend to a depth of five feet; temporary soil gas probes will be installed in each of these borings <br /> for soi gas same ing. ne of t e orings will extend to groundwater (anticipated depth on the <br /> order of 20 to 30 feet) and a grab groundwater sample will be collected from the boring. <br /> Following the sampling, the soil gas probes will be removed from the five-foot-deep borings and <br /> all borings will be backfilled with neat-cement grout in accordance with County requirements. <br /> The collected soil gas and groundwater samples will be submitted to a State-certified laboratory <br /> for analytical testing. The soil gas samples will be analyzed for volatile organic compounds <br /> (VOCs) by EPA Method TO-15. The groundwater sample will be analyzed for total petroleum <br /> hydrocarbons by EPA Method 80156 and VOCs by EPA Method 8260. <br /> Data Evaluation and Reporting <br /> Upon receipt, the laboratory results will be tabulated and reviewed. A summary report will be <br /> prepared that will include descriptions of our procedures and observations, a scaled site plan <br /> drawing, the chemical data, the results of our evaluation, and the signature and stamp of the <br /> Professional Geologist in charge of the project. <br /> CLOSING <br /> If you have any questions or require additional information, please contact the undersigned at <br /> (916)-385-0202. <br /> Sincerely, <br /> GEOGRAPHIC SERVICES INC. <br /> Ruxandra Niculescu, REM <br /> Environmental Professional <br /> Attachments: Site Map showing planned boring locations <br /> Safety Plan <br />
