Sacramento Street Page 2 <br /> Our Project Number: E07087k <br /> May 30, 2007 <br /> Four soil and four soil vapor samples will be collected along the site boundaries shared with the <br /> Holz Rubber at locations to be determined by on-site personnel. Two boreholes will be located <br /> at each of the two possible locations of the former under ground storage tanks. A total of eight <br /> soil boreholes and four soil gas boreholes will be drilled. Approximate locations are depicted on <br /> Plate 2. Boreholes will be advanced by Geoprobe Rig (Enprob of Oroville, California) to 25 feet <br /> below ground surface (bgs). Sample collection depths will be determined by screening the <br /> cuttings with a photoionization detector (PID). <br /> 1.2 Access Agreement <br /> NOA is performing the work for a representative of the property owner. A signed access <br /> agreement will be forwarded before start of work. <br /> 2.0 HEALTH AND SAFETY PLAN <br /> We anticipate that the health hazards that will be encountered at the Site will be minimal. <br /> Based on our understanding of the past disposal practices at the Site, we do not expect to <br /> encounter any liquid or solid waste materials nor any liquid or solid hazardous waste materials <br /> at the proposed drilling locations. However, if waste materials are encountered, we anticipate <br /> that the primary mode of contaminant exposure will be through the skin as a result of handling <br /> equipment, soil, and water. Therefore, we have prepared the following Health and Safety Plan: <br /> 1) Level D Protection. We propose that all field activities be conducted consistent <br /> with Level D protection requirements as defined by the California Occupational Safety and <br /> Health Administration (OSHA). The minimal required Level D protection equipment includes <br /> hard hat, safety glasses, steel-toed boots, earplugs, disposable rubber gloves, and appropriate <br /> work clothing. <br /> 2) Emergency Treatment. In the event of an emergency, a member of the team <br /> will dial 911 and follow the instructions of the operator. In the event that a non-emergency <br /> injury occurs to any or all of the team, they will be transported to the nearest hospital that <br /> provides emergency room services (Lodi Memorial Hospital, 900 South Fairmont Avenue, Lodi, <br /> 209-333-2500). <br /> 3.0 SOIL SAMPLING PROCEDURES <br /> 3.1 Drilling Details <br /> All drilling activities will be performed by Enprob of Oroville, California. <br /> 3.1.1 Drilling Method <br /> The boring(s) along the property line will be advanced with a 2-inch diameter truck mounted <br /> geoprobe rig. The soil cuttings brought to the surface will be examined and placed on plastic. <br /> Disposal will be based on the analytical results. The soil gas samples will be collected by using <br /> geoprobe equipment and Summa canisters. The soil samples will be collected into clean brass <br /> tubes, sealed with Teflon, and capped. <br /> 'A4 <br /> 902 Industrial Way•Lodi,CA 95240.209.367.3701 •Fax 209.369.4228 02007 Nei!0.Anderson&Associates,Inc <br />
