PROCEDURE <br /> GHD will obtain all permits to perform drilling work unless contractually directed otherwise. GHD will <br /> prepare a site Safety and Health Plan detailing project hazards and controls, personnel <br /> decontamination, and emergency response procedures. <br /> At least 48 hours before drilling, GHD personnel will contact Underground Services Alert(USA), or <br /> similar utility location service, to have subsurface utilities located and marked within the work area <br /> previously delineated with white paint. In order to ensure that the locations of subsurface utilities are <br /> known, GHD may perform a site inspection, contact individuals familiar with the work site, review as- <br /> built <br /> drawings, <br /> feet of each boring will be ad ay a dvanced utility <br /> uslocator. <br /> ing a hand augersubsurface <br /> or postholeutilities <br /> diggerare suspected, the <br /> All monitoring wells are installed using a truck-mounted hollow-stem auger drill rig, unless site <br /> conditions require a different drilling method. All drilling equipment will be maintained and inspected <br /> daily. A drill rig kill switch mechanism will be operational and within reach of anyone working near the <br /> drill. <br /> All down-hole drilling equipment will be cleaned and decontaminated prior to arriving at the site. <br /> Working components of the drill rig, drill stems, and augers are steam cleaned between monitoring well <br /> locations. <br /> Whenever possible, the first boring will be sampled to provide a continuous core to obtain a complete <br /> lithologic section of the boring. In subsequent borings, soil samples will be collected at approximately <br /> five-foot intervals to the total depth explored. Soil samples may also be collected from differing <br /> lithologies or areas of obvious contamination. Samples will be collected using a California-modified split <br /> spoon sampler driven 18 to 24 inches into native material beyond the auger bit. The split spoon will be <br /> driven using a 140-pound hammer dropped from 30 inches.
