Work Plan:Environmental Sampling of Soil Export Materials <br /> 1517 N.California St. <br /> Page 2 <br /> plan is included in Appendix B. Personnel working at the Site will have completed 40 hours of classroom <br /> training (OSHA 29 CFR 1920.120, HAZWOPER) and 24 hours of supervised field training concerning <br /> hazards that may be encountered at hazardous waste Sites. Additionally, field personnel working at the <br /> Site will participate in a medical monitoring program. <br /> 3.3 DIRECT PUSH BORING PROCEDURES <br /> A total of 16 direct push borings will be advanced on the Site. The proposed boring locations are shown <br /> on Figure 3 in Appendix A. The eight borings located on APNs 127-150-23, 127-150-24, and 127-150-25 <br /> will be advanced to approximately eight feet below ground surface (bgs) and the eight borings on APNs <br /> 127-15048 and 127-150-49 will be advanced to approximately 12 feet bgs. Groundwater is anticipated to <br /> be between 40 and 50 feet bgs. <br /> Continuous core soil samples will be collected from the boring with a 1.75-inch O.D., 4-foot long core <br /> barrel fitted with a clean, single use, polyethylene liner. The soil sampling equipment will be cleaned <br /> prior to collecting the sample using laboratory-grade, non-phosphate detergent and deionized water and <br /> double rinsed with deionized water. During the sampling, the core barrel will be driven in 4-foot <br /> intervals. The sample liner will be extracted from the core barrel and used for geological logging and <br /> field observations. The soil samples will be logged according to the Unified Soil Classification System <br /> (USCS). Portions of the soil samples will be placed in polyethylene bags and checked with a <br /> photoionization detector (PID) for the presence of volatile hydrocarbons. Geological logs will be <br /> prepared containing field observations including soil type, estimated moisture content, PID <br /> measurements, and the presence of staining or odor. <br /> Eight direct-push borings will be advanced on the western portion of the Site to eight feet below ground <br /> surface (bgs), and eight direct-push borings will be advanced to 12 feet bgs on the eastern portion of the <br /> Site. Soil samples will be collected from each of the eight western borings at three feet bgs. On the <br /> eastern portion of the Site, soil samples will be collected at three and nine feet bgs, or wherever <br /> contaminated soil is identified using field methods. Any soil cuttings with identified contamination using <br /> field methods will be placed in a 55-gallon drum, sealed, labeled, and left on-Site to await disposal <br /> pending results of the laboratory analyses. Following the collection of the soil samples, the borings will <br /> either be abandoned with drill cuttings and remaining void space will be grouted to surface with neat <br /> cement, or the borings will be completely grouted to the surface. <br /> Each soil sample collected for laboratory analyses will be cut from the liners. The liners will be sealed at <br /> the ends with Teflon® sheeting, capped, and labeled. The samples will be placed in a cooler chilled with <br /> Blue Ice© and delivered under chain-of-custody procedures to a California certified laboratory for <br /> analyses. <br /> 3.4 LABORATORY ANALYSES <br /> Upon completion of the fieldwork, the soil samples will be delivered under chain-of-custody procedures <br /> to a state certified laboratory for analyses. The soil samples will be composited by the laboratory at a 4- <br /> to-1 ratio based on depth and location, for a total of six composite soil samples. The composite soil <br /> samples will be analyzed for total petroleum hydrocarbons (TPH) quantified as gasoline, diesel, <br /> kerosene, and motor oil by EPA Method 8015M, volatile organic compounds (VOCs) by EPA Method <br /> 8260B, organochlorine pesticides by EPA Method 8081B, polychlorinated biphenyls (PCBs) by EPA <br /> 4Vs lkki�. <br /> I.1) CONDOR <br />
