1 <br /> t• L Owens Ford Co. <br /> Soil Investigation Work Plan <br /> June 20,1996 <br /> ' Page-2. <br /> 2.2 Excavation <br /> ' The excavation will be performed by Erickson Inc., of Richmond, California. A Condor <br /> geologist will be on site to supervise the excavation and collect soil samples. A tailgate safety <br /> ' meeting will be held and a Health and Safety Plan will be discussed with, and presented to, all crew <br /> members upon arrival at the site. A copy of the Health and Safety Plan is contained in the Appendix <br /> ' of this document. <br /> ' It is anticipated that approximately 50 to 100 cubic yards of soil will be excavated during the <br /> investigation. Condor will screen the excavated soil using an organic vapor analyzer (photoionization <br /> detector - PID). In addition, the soil will be logged according to the Unified Soil Classification <br /> System, including visual presence of petroleum product, odor, or staining. Contaminated soil will be <br /> ' placed on plastic sheeting adjacent to the work area. Clean overburden will be segregated from the <br /> contaminated soil pile. Upon completion of the soil removal and sampling, the excavation will be <br /> backfilled with clean soil or left open and surrounded with barracades and safety tape pending the <br /> laboratory results. <br /> ' 2.3 Soil Samples <br /> Soil samples will be collected from the final excavation for chemical analyses. One soil <br /> sample will be collected every 10 lineal feet of piping. Additional samples may be collected at the <br /> discretion of the geologist or PHS/EHD representative. The soil samples will be collected using a <br /> ' hand held, rod mounted, soil sampler fitted with a clean brass liner. The sampler will be <br /> decontaminated prior to collecting each sample. The decontamination procedures will consist of <br /> ' washing the sampler in laboratory grade, non-phosphate detergent and hydrocarbon free water, and <br /> rinsing the sampler in hydrocarbon free water. The soil samples will be retained, undisturbed, in the <br /> ' brass liners. The liners will be sealed at the ends with Teflon tape, capped, wrapped with duct tape, <br /> and labeled. The samples will be stored in a cooler chilled with ice and delivered within 24 hours of <br /> collection, under chain-of-custody procedures, to GeoAnalytical Laboratories in Modesto, California. <br /> 1 <br /> N� <br /> i� CONDOR <br /> 1 <br />
