Work Plan:Environmental Sampling of Soil Export Materials 1506 N.California St. Page 2 plan is included in Appendix B. Personnel working at the Site will have completed 40 hours of classroom training (OSHA 29 CFR 1920.120, HAZWOPER) and 24 hours of supervised field training concerning hazards that may be encountered at hazardous waste sites. Additionally, field personnel working at the Site will participate in a medical monitoring program. 3.3 DIRECT PUSH BORING PROCEDURES Twenty direct push borings will be advanced on the Site. The proposed boring locations are shown on Figure 3 in Appendix A. All of the borings will be advanced to approximately 16 feet below ground surface (bgs): groundwater is anticipated to be between 40 and 50 feet bgs. Continuous core soil samples will be collected from the boring with a 1.75-inch O.D., 4-foot long core barrel fitted with a clean, single use, polyethylene liner. The soil sampling equipment will be cleaned prior to collecting the sample using laboratory-grade, non-phosphate detergent and deionized water and double rinsed with deionized water. During the sampling, the core barrel will be driven in 4-foot intervals. The sample liner will be extracted from the core barrel and used for geological logging and field observations. The soil samples will be logged according to the Unified Soil Classification System (USCS). Portions of the soil samples will be placed in polyethylene bags and checked with a photoionization detector (PID) for the presence of volatile hydrocarbons. Geological logs will be prepared containing field observations including soil type, estimated moisture content, PID measurements, and the presence of staining or odor. Soil samples will be collected from the borings for laboratory analyses at 3.5, 10, and 16 feet bgs, or wherever contaminated soil is identified, for a total of three soil samples per boring. Any soil cuttings with identified contamination using field methods will be placed in a 55-gallon drum, sealed, labeled, and left on-site to await disposal pending results of the laboratory analyses. Following the collection of the soil samples, the borings will either be abandoned with drill cuttings and remaining void space will be grouted to surface with neat cement, or the borings will be completely grouted to the surface. Each soil sample collected for laboratory analyses will be cut from the liners. The liners will be sealed at the ends with Teflon® sheeting, capped, and labeled. The samples will be placed in a cooler chilled with Blue Ice® and delivered under chain-of-custody procedures to a California certified laboratory for analyses. 3.4 LABORATORY ANALYSES Upon completion of the fieldwork, the soil samples will be delivered under chain-of-custody procedures to a state certified laboratory for analyses. The soil samples will be composited by the laboratory at a 4- to-1 ratio based on depth and location for a total of 15 composite soil samples (5 composite soil samples per depth). The composite soil samples will be analyzed for total petroleum hydrocarbons (TPH) quantified as gasoline, diesel, kerosene, and motor oil by EPA Method 8015M, volatile organic compounds (VOCs) by EPA Method 8260B, organochlorine pesticides by EPA Method 8081B, polychlorinated biphenyls (PCBs) by EPA Method 8082, and CAM 17 Metals by EPA Methods 6010B and 7417A. lkkii�6 �.a CONDOR
