The Driller is responsible for installing monitoring wells according to pertinent agency <br /> standards. <br /> 4. Equipment Required <br /> • Well Installation permit,Access Agreements, and other permits as needed <br /> • Copy of approved Workplan with site Safety Plan included <br /> • Minimum Level D personal protective equipment <br /> • Downhole sampler with brass or stainless steel liners, Teflon sheeting, and end caps <br /> • Photoionization detector(PID)/sealable plastic storage bags <br /> • Boring Log form/Munsell color charts/USCS soil classification system chart <br /> • Sample containers-provided by the laboratory OR <br /> • EnCore®Sampling kit and soil cartridge containers <br /> • Sample labels/Indelible marker/Chain of Custody forms <br /> • Disposable gloves <br /> • Ice chest with ice <br /> 5. Procedure <br /> Winzler&Kelly will obtain all permits to perform drilling work unless contractually directed <br /> otherwise. Winzler&Kelly will prepare a site Safety and Health Plan detailing project hazards and <br /> controls,personnel decontamination, and emergency response procedures. <br /> At least 48 hours before drilling, Winzler& Kelly personnel will contact Underground Services Alert <br /> (USA), or similar utility location service,to have subsurface utilities located and marked within the <br /> work area previously delineated with white paint. In order to ensure that the locations of subsurface <br /> utilities are known, Winzler& Kelly may perform a site inspection, contact individuals familiar with <br /> the work site,review as-built drawings, and may employ a private utility locator. When subsurface <br /> utilities are suspected,the first 5 feet of each boring will be advanced using a hand auger or posthole <br /> digger. <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 <br /> inspected daily.A drill rig kill switch mechanism will be operational and within reach of anyone <br /> working near the 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 <br /> well 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 <br /> approximately 5-foot intervals to the total depth explored. Soil samples may also be collected from <br /> differing lithologies or areas of obvious contamination. Samples will be collected using a California- <br /> modified split spoon sampler driven 18 to 24 inches into native material beyond the auger bit. The <br /> split spoon will be driven using a 140-pound hammer dropped from 30 inches. The number of blow <br /> counts required to drive the sampler each six-inch interval and the volume of soil recovered will be <br /> SOP MW Install&Dev 2 of 6 August 2011 <br />
