Phase II Work Plan <br /> 20 E.Lindsay St. <br /> Page 2 <br /> information such as potential hazards encountered at the site, personal protective equipment, and <br /> directions and telephone numbers to the nearest hospital. A copy of the site-specific health and safety <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 /> Six direct push borings will be advanced within the property. The proposed boring locations are shown <br /> on Figure 3 in Appendix A. All of the borings will be advanced to approximately 15 feet below ground <br /> surface(bgs), above the water table: groundwater is anticipated to be deeper than 15 feet bgs. <br /> The direct push borings will be hydraulically advanced using a 2-inch diameter conical bit. The bit and <br /> associated push rods will be thoroughly cleaned before each boring is advanced using laboratory-grade, <br /> non-phosphate detergent and deionized water and double rinsed with deionized water. Upon completion <br /> of the borings and sampling,the borings will be grouted with neat cement. <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. Soil samples will be collected from the borings for <br /> laboratory analyses at five-foot intervals beginning at 5 feet bgs, or wherever contaminated soil is <br /> identified, for a maximum of three soil samples per boring. The soil cuttings will be placed in a 55-gallon <br /> drum, sealed, labeled,and left on-site to await disposal pending results of the laboratory analyses. <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 collected from the borings will be analyzed <br /> for TPH-G, TPH-D, TPH-MO, and TPH-K by EPA Method 8015B, for VOCs by EPA Method 8260B, <br /> and for BTEX and gasoline oxygenates/additives by EPA Method 8260B. The gasoline <br /> additives/oxygenates include tertiary-butanol (TBA), methyl tertiary-butyl ether (MTBE), di-isopropyl <br /> ether (DIPE), ethyl tertiary-butyl ether (ETBE), tertiary-amyl methyl ether (TAME), and 1,2- <br /> dichloroethane (1,2-DCA). In addition, soil samples with visual or olfactory indications of hydrocarbon <br />
