"AWNVAWMM <br /> Working To Restore Nature <br /> FIELD METHODS <br /> Safety Plan <br /> The site safety plan dated January 12; 1993, describes the basic safety requirements for the <br /> drilling of soil borings at the work site and was generated for the upcoming investigation. <br /> The safety plan is applicable to personnel and subcontractors of RESNA. The RESNA <br /> representative will be the Site Safety Officer.' Personnel at the site will be informed of the <br /> contents of the site safety plan before work begins. A copy of the plan will be kept at the <br /> work site and will be available for reference by appropriate parties during the work. <br /> Drilling Procedures <br /> Before drilling, we acquired a permit from the SJCPHS-EHD to hand-auger four soil <br /> borings. RESNA contacted Underground Service Alert at least 48 hours before drilling to <br /> delineate public utility lines at the site. <br /> RESNA hand-augered four 3-inch-diameter soil borings. The earth materials were <br /> identified using visual and manual methods. Soil generated by augering was examined for <br /> subjective evidence of volatile chemicals, oil and grease, pesticides, etc. such as soil <br /> discoloration or obvious odor. <br /> Collecting Soil„Samples <br /> During augering, soil samples were collected at 5-foot intervals using a hand-driven <br /> percussion sampler equipped with clean brass sleeves. Samples were collected by augering <br /> the boring to a point just above the sampling depth and then driving the sampler 6 inches <br /> into the native soil. <br /> Soil samples collected for possible chemical analysis were promptly sealed with Teflon tape <br /> and plastic caps. They were then labeled and placed in iced storage for transport to the <br /> analytical laboratory. A Chain of Custody Record will be initiated by the field technician <br /> and accompanied the soil samples to the laboratory. <br /> 0128jcom <br /> 32073-I <br />
