Attachment B <br />1) Reclamation cost estimate for the Grout Integrity Test Holes <br />A proposed 3-3/4" diameter hole intended to intersect the basin <br />underneath either EF 1 or EF3 would be approximately 300 ft long and <br />have a capacity of 23 cubic ft. Similar holes from the side of either <br />EF 1 or EF3 would be approximately 150 ft long and have a capacity <br />of 11.5 cubic ft. The total abandonment volume of four 300-ft holes <br />and eight 150-ft holes would be 184 cubic ft. <br />• Typically, a slurry of one 94-1b sack of cement (Type I/II) and six <br />gallons of water fills a volume of 1.28 cubic ft. So, 144 sacks of <br />cement are required to cement all 12 holes to surface. A typical <br />pallet of cement contains 40 sacks. Assuming some volume will <br />be lost to waste, eight pallets or 320 sacks will be required. At <br />$10/sack this will be $3200. <br />• Labor cost for three days work by 2 people (10hrs/day, $100/hr) <br />will be $6000. <br />• Rental of a cement mixer/pump (3 days @ $100/day) will be $300. <br />• Rental of an air compressor (3 days @ $100/day) will be $300. <br />• Rental of a Pickup Truck (3 days @ $100/day) will be $300. <br />• Hotel and food for the crew will be $500. <br />Total reclamation cost for up to 12 test holes is estimated to be <br />$1000. With 100% contingency, the reclamation cost could be as <br />high as $21,200. <br />Technical Revision Submittal
