Additionally, <br /> a site-specific health and safety plan will be prepared for our personnel. Kleinfelder will request <br /> that the drilling subcontractor contact Underground Service Alert to notify local utilities of our <br /> planned activities prior to conducting field activities. <br /> field Activities <br /> Shallow Barings <br /> Kleinfelder proposes to advance four shallow soil probes to approximately 8 feet below the <br /> ground surface (bsg). Two of the probes will be advanced in the leach field near the closest <br /> point of discharge from the septic rank. Two additional probes will be advanced near the leach <br /> field at the furthest extent of the leach lines from the septic tank <br /> The exploratory soil probes will be advanced using a truck mounted Geoprobe rig. The <br /> Geoprobes will be advanced using a pneumatically driven steel probe. Soil samples will be <br /> obtained by inserting a sample barrel, lined with acetate liners, into the probe. Soil samples will <br /> be continuously collected from the probes. Soil samples will be collected for porential analyses <br /> at a minimum of 4-foot intervals beginning at a depth of four feet and stopping at approximately <br /> 8 feet bgs. <br /> While sampling, an experienced enviromnental geologist will classify the subsurface soils <br /> generated by the advancing probes. Soil samples will be collcmd by cutting out the desired <br /> interval from a continuous core interval (successive 4 foot acetate liners) and sealing the ends <br /> with Teflon sheeting and tight fitting plastic caps. Each sample will be individually labeled and <br /> placed in an iced cooler pending transport to the analytical laboratory under chain of custody <br /> protocols. Soil cuttings generated during fieldwork will be placed in plastic bags. The borings <br /> will be closed in accordance with PHS/EHD guidelines by grouting to the surface, <br /> Laboratory &aajysis <br /> Two soil samples from each of the four shallow probes will be submitted to a laboratory certified <br /> by the State of California for the proposed analyses. The samples submitted for analyses will be <br /> based upon field observations and will be collected between 4 to 8 feet bgs. The samples will be <br /> analyzed for: <br /> • Total Extractable Petroleum Hydrocarbons as motor oil (TPH-mo) by EPA Method 80 ISM, <br /> Silica gel clean-up <br /> • Total Extractable Petroleum Hydrocarbons as diesel ("TPH-d)by EPA Method 8015M <br /> Silica go]clean-up <br /> 20-YPi,50912011 P069r2011w(10j <br /> Copyright 2001.Klcinfelder,Inc.
