Page 3 <br /> Hand Exploration <br /> i <br /> Additional data regarding soil conditions along pipeline r es and possible borrow areas <br /> can be developed by logging the exposed slopes of the existing ditches, and via hand <br /> augers. There may locations where the geotechnical engineer wishes to supplement the <br /> planned exploration by drilling 3-inch diameter hand auger borings to not deeper than 12 <br /> feet and/or by pushing a3/4-inch hand penetrometer to no deeper than 12 feet. The hand <br /> auger borings will be back filled with soil cuttings. No specific locations are set for the hand <br /> exploration. The geotechnical engineer will get permission from the Farm Manager before <br /> conducting hand exploration at locations other than those where CPTs and borings are <br /> made. <br /> L <br /> 59205 Field Exploration Ltr_draft_KW-EH.cpm rev07.20.06 <br />
