' KLE/NFELOER <br /> will be removed, and the selected sampling interval will be sealed with Teflon sheets and plastic <br /> end caps. <br /> Soil samples will be collected continuously during the advancement of the pushprobes at <br /> depths ranging from the aggregate roadway base rock and soil interface to the proposed <br /> maximum depth of approximately 6 feet bgs. During the advancement of the borings, soil <br /> samples will be collected using a Photo Ionization Detector (PID) for lithologic classification and <br /> qualitative field screening. The PID measures ionizable compounds in air in parts per million by <br /> volume. Lithologic classification will be based on the Unified Soil Classification System. <br /> Kleinfelder proposes collecting one soil sample in each of the nine probes along the alignment <br /> for potential chemical analyses. These soil samples will be collected at intervals ranging from <br /> the base on the roadway section, estimated at 2'/ feet bgs, to approximately six feet bgs. This <br /> may vary depending upon field observations indicating evidence of petroleum impacted soils. <br /> However, we estimate that one soil sample collected from each boring will be sufficient for the <br /> purposes of this assessment. <br /> After collection, the soil samples will be labeled, logged on a chain-of-custody form, and <br /> immediately stored in an iced cooler. The samples will be transported under chain-of-custody <br /> control to Kleinfelder's office and then transported by courier in a chilled container to a State <br /> accredited laboratory to perform the requested analyses. Kleinfelder is proposing submittal of <br /> one soil sample from each boring location (total of 9) during the pushprobe investigation for the <br /> following analyses: <br /> • Total Extractable Petroleum Hydrocarbons (Diesel Range) [TPHd] by EPA Method <br /> 8015M/DHS LUFT <br /> • Total Purgeable Petroleum Hydrocarbons (Gasoline Range [TPHg] by EPA <br /> Method 8015M <br /> • Volatile Organic Compounds by EPA Method 8260B <br /> The samples will be submitted on a standard 5 to 10 business day turn-around time. <br /> Reporting <br /> Upon completion of the field activities and receipt of the analytical results a report of findings <br /> will be developed which will include the following: <br /> • Project description and scope of work; <br /> • A description of the field activities, observations, and protocols; <br /> • Tabulated results of soil samples with copies of certified analytical results; <br /> • A graphical representation of sample locations; and <br /> 133385.2/ST013L0278 Page 2 of 4 <br /> Copyright 2013 Kleinfelder April 2, 2013 <br />
