FIELD PROCEDURES <br /> SOIL SAMPLING AT TANK REMOVALS <br /> Site Safety Plan <br /> The Site Safety Plan describes the basic safety requirements for field activities at the site. The Site <br /> ' Safety Plan is applicable to personnel of Lee & Pierce, Inc. (L&P) and to subcontractors of L&P. <br /> Personnel scheduled to work at the site will be briefed on the contents of the Site Safety Plan before <br /> work begins. A copy of the Site Safety Plan will be kept at the work site and will be available for <br /> reference by appropriate parties during work at the site. The onsite representative of L&P will be <br /> designated the Site Safety Officer. <br /> ' Sample Collection during Tank Removal <br /> Soil samples will be collected as soon as possible after removal of the tank. Where feasible, all <br /> preparations for soil sampling will be made prior to tank removal. Soil samples collected from a <br /> backhoe bucket or directly from the excavation floor will be collected in a thin-walled stainless steel <br /> or brass cylinder at least three inches long by one inch in diameter. From 3 to 24 inches of soil will <br /> be removed from the immediate surface area where the sample is to be taken and the cylinder then <br /> pounded into the soil with a wooden mallet, bulk density driver, or other decontaminated driving <br /> device. No head space will be present in the cylinder once the sample is collected. Care will be <br /> taken to avoid contamination of both the inside and outside of the cylinder as well as its contents. <br /> During sampling,latex gloves will be worn to prevent cross contamination with other samples. One <br /> pair of disposable gloves will be dedicated to each sample collected. <br /> Samplinz from Soil Piles or Shallow Soil Pits <br /> ' Soil samples will be collected and transported from excavated material in the manner described in <br /> the previous section, however, a backhoe will not be utilized. If composite samples are collected, <br /> two brass cylinders will be collected for every 50 cubic yards of material to be sampled unless <br /> ' otherwise specified by the lead regulatory agency. The samples will be composited by the state <br /> certified analytical laboratory personnel prior to testing. <br /> Sample Labeline and Handline <br /> Soil samples selected for laboratory analysis are removed from the sampler and quickly sealed in <br /> ' their brass sleeves with Teflon sheets and plastic caps. The respective sample containers are labeled <br /> in the field with the job number, sample location, depth if applicable, and date, and promptly placed <br /> in iced storage for transport to the laboratory. Chain of Custody Records are initiated in the field by <br /> the geologist and accompany the samples to a laboratory certified by the State of California to <br /> perform the analyses requested. <br /> Page 1 of 2 <br /> SOP_FLDTANK <br />
