pipe from a 20,000 gallon tank added directly into the truck bed sump. The haul truck bed was chosen for <br /> this purpose as it was the most efficient and cost effective repository for this process. The haul truck bed <br /> will be fenced and netting will be placed over the sump in order to deter wildlife, per CC&V's approved <br /> Wildlife Management Plan. <br /> The ore/lime mixture will be removed from the bottom of the truck bed sump and hauled by truck to both <br /> of the VLFs (AG and Squaw Gulch) for further recovery. This solid mixture, in turn, will further increase <br /> the pH of the VLFs,which will aid recovery. Prior to removal,the Phase II solution valve will be shut off. <br /> Once removal is complete, slaked lime will be added to the sump and the valve will be turned on again; <br /> reintroducing Phase TI solution to the sump. The solid mixture is anticipated to be removed annually; <br /> although the actual frequency may vary upon implementation. <br /> The de-scaled solution will then overflow from the truck bed into a new, 3,000 square foot infiltration <br /> sump, where it will percolate through the VLF and into the Phase I caissons where it will combine with <br /> Phase I Pregnant solution. There will be an emergency overflow infiltration sump located directly east of <br /> the main infiltration sump. The Phase I pumps will transport the combined solution from the Phase I to <br /> the existing Pregnant Solution Tank. Figure 3 details this proposed modification flow. <br /> Attachment 1, included in this submission, details specific flow rate ranges and operating parameters for <br /> this process; so as to not negatively impact the geotechnical stability of the VLF. <br /> Implementation Schedule: <br /> Pending DRMS approval and recommendations of one of these modification options, CC&V will begin <br /> construction immediately. <br /> Financial Warranty: <br /> CC&V utilized the RS Means costs for calculating the reclamation cost for removal of the haul truck bed <br /> sump. The estimated increase for the removal of the haul truck bed sump is $2,885.48 and was entered as <br /> "selective demolition, steel tank, single wall, above ground, 15,000 thru 30,000 gallons", (RSMeans# <br /> 130505750540). <br /> Enclosed please find check no. 200037522 in the amount of $1,006.00 for the technical revision fee. <br /> Should you require further information please do not hesitate to contact Katie Blake at 719.689.4056 or <br /> Katie.Deli lin(conewmont.com or myself at 719.689.4055 or Mel Burt(a newmont.com. <br /> Sincerely, <br /> Meg Burt <br /> Senior Environmental Manager <br /> Cripple Creek and Victor Gold Mine <br /> MB/kb <br /> Ec: Tim Cazier,DRMS <br /> Attachments: 1 <br /> Figures:3 <br /> 2 <br />
