Project# <br /> Holz Rubber Co.,Inc. <br /> Lodi,California <br /> field-screening to be the most contaminated or, in the absence of evidence of contamination, the <br /> deepest sample collected from each boring. <br /> Soil boring and sampling will be performed under the direction of a California Registered <br /> Professional Engineer or Geologist. <br /> SAMPLE COLLECTION <br /> Soil samples to be submitted for laboratory analysis will be collected by driving a pre-cleaned <br /> brass sample sleeve into the soil at the bottom of the borehole using a slide-hammer sampler. <br /> Brass sleeves containing soil samples will be extracted from the sampling device. The ends of the <br /> brass sleeves will be sealed with Teflon sheets followed by aluminum foil and tight-fitting plastic <br /> caps. The plastic caps will be secured to the ends of the sleeves with chain-of-custody seals. The <br /> brass sample sleeves will be labeled with unique identification numbers, time and date of sample <br /> collection, and the name of the sample collector. Labeled samples will be placed in sealable <br /> plastic bags on ice in coolers, cooled to a temperature of approximately 4°C and preserved. <br /> Samples will be transported in coolers under chain-of-custody via overnight air freight for <br /> laboratory analysis. <br /> SAMPLE ANALYSES <br /> The samples will be submitted to a California Certified analytical laboratory for analysis. Samples <br /> collected from borings in the vicinity of the dip tanks and flammable material storage structure <br /> will be analyzed for CAM 8 metals, pH, and VOCs. Samples collected from between Building 5 <br /> and Building 6 will be analyzed for total petroleum hydrocarbons (TPH) as diesel and total oil and <br /> grease (TOG). Samples collected from the vicinity of Building 17 will be analyzed for TPH as <br /> diesel and TOG. Samples collected from around Building 16 will be analyzed for VOCs and <br /> TOG. <br /> DECONTAMINATION <br /> All equipment anticipated to contact soil samples will be decontaminated prior to sampling and <br /> between each sampling event. Decontamination will consist of rinsing equipment in tap water to <br /> remove gross contamination followed by washing in distilled water with Alconox°, Liquinoz, or <br /> Citrinox° detergent followed by a distilled water rinse and air drying. Decontaminated sampling <br /> equipment will be placed on clean aluminum foil to air dry. Decontaminated sampling equipment <br /> will be wrapped in clean aluminum foil between sampling events. <br /> INVESTIGATION-DRIVEN WASTE HANDLING <br /> Soil cuttings will be drummed and left on site until the laboratory analytical results are received. <br /> Laboratory analytical results will be used to characterize the cuttings and they will be <br /> subsequently disposed of in an applicable manner. Protective clothing, if any, and latex gloves <br /> used during investigation will be placed in plastic trash bags, and disposed as common refuse. <br /> July 1996 2 <br /> g:ladmin1correspU9776sms.doc <br />
