trucks, properly labelled, and shipped to an appropriate treat- <br /> ment/disposal facility if determined to be contaminated. The <br /> estimated volume of excavation material is approximately 30 cubic <br /> yards. Shipment of all wastes will be performed by licensed <br /> haulers. <br /> 7. 0 SAMPLING AND ANALYSIS PLAN <br /> Soil samples will be collected at the locations specified in the <br /> closure steps. Samples will be collected using a driven-tube type <br /> sampler or from a backhoe scoop by inserting a brass tube into the <br /> retrieved soils and then capped and sealed to minimize volatiliza- <br /> tion of any volatile materials present in the sample. Water <br /> samples will be collected with a bailer or other sampling device <br /> that would minimize volatilization of the sample. The water sample <br /> will then be transferred to appropriate laboratory prepared bottles <br /> for sample analyses. All VOA vials are to be filled with as little <br /> agitation as possible, and a teflon lined septum seals the vials so <br /> that no air is present in the sample. Chain-of-Custody records <br /> will be maintained from sample collection to laboratory receipt <br /> for all samples collected. Samples are cooled to 4°C until sample <br /> analysis, and analyzed within the specified holding times. <br /> The samples will be analyzed by a California DHS State certified <br /> laboratory. Sample analysis will be performed in accordance with <br /> EPA methodologies in Test Methods for Evaluating Solid Waste. <br /> Physical/Chemical Methods and Methods for Chemical Analysis of <br /> Water and Wastes. <br /> Sampling equipment will be decontaminated between each sampling <br /> location. The equipment will be cleaned with alconox or a similar <br /> detergent soap, followed by a rinse with distilled water. The <br /> backhoe bucket is to be steam-cleaned prior to and between each <br /> sample collection location. A hexane solvent (laboratory-grade) <br /> may also be used to remove any petroleum products. Equipment will <br /> be completely air dried before use. <br /> 8. 0 SITE SAFETY PLAN <br /> A site safety plan will be provided by the contractor performing <br /> p the closure of the underground storage tank. The following items <br />! will be required in the plan: <br /> o Background information on the tank. <br /> o Identification of the key personnel for the project, <br /> including their health and safety responsibilities. <br /> o Identification of the potential job hazards, both <br /> chemical and physical. <br /> o Summary of risks/impacts on receptors at or near the job <br /> location. <br />
