WORK PLAN <br /> THERMO KING STOCKTON <br /> 1950 East Miner Road <br /> Stockton, California <br /> Terracon Project No. 67047008 <br /> Terracon completed a Phase I Environmental Site Assessment report dated September 22, <br /> 2004 for the property owners of the Thermo King facility located at 1950 East Miner Road in <br /> Stockton, California. Based on site observations and interviews, collection of a subsurface soil <br /> sample from the truck wash area was recommended. Potential contaminants are petroleum <br /> and VOCs and the laboratory analyses recommended were TPH by EPA Method 8015 and <br /> VOCs by EPA Method 8260. A Site Plan is attached. <br /> Terracon has contracted with a California licensed well driller to advance one direct push type <br /> (Geoprobe) soil boring in the wash rack area and to collect one soil sample from the boring. A <br /> site specific Health and Safety Plan will be prepared for the site activities. A minimum of 72 <br /> hours prior to drilling activities the drilling location will be outlined with white paint and <br /> Underground Service Alert will be notified to clear utilities at the drilling location. <br /> Soils recovered from the boring will be monitored for staining, odor, and OVM readings. The soil <br /> horizons in the boring from the ground surface to total depth will be screened in the Feld with a <br /> Thermo Environmental Instruments Inc. Model 580BTM photoionization Organic Vapor Meter <br /> (OVM). The soil screening will be performed to identify the potential presence of contamination <br /> through visual observations and volatile organic compound screening with the OVM. <br /> Representative soil material for the screening will be collected from the Geoprobe soil samples. <br /> The anticipated maximum depth of the boring is 20 feet below ground surface. The soil sample <br /> will be collected by one of two methods. Method one will be to cut an approximately six-inch <br /> section from the 4-foot acetate tube and seal the ends with caps and tape. Method two will be <br /> to transfer soil from the acetate tube into 4-ounce laboratory sample jars. All samples will be <br /> labeled and preserved on ice at an approximate temperature of four degrees Celsius. <br /> Proper chain of custody protocols will be followed throughout. The soil sample will be delivered to <br /> a California certified analytical laboratory for analysis for Total Petroleum Hydrocarbons by EPA <br /> Method 8015B and for VOCs by EPA Method 8260. <br /> After completion of the drilling and sampling activities the boring will be backfilled with neat <br /> cement. Any soil cuttings generated by the drilling activities will be containerized in a fifty-five <br /> gallon drum for subsequent off-site disposal with a licensed waste disposal contractor pending the <br /> receipt of laboratory analysis. <br /> 1 <br />
