Stevens Division of Minerals and Geology 1313 Sherman Street DENVER COLORADO 80203-2273 RECEIVED FEB 25 1999 Regarding: Craig Pit M-99-011 Deaz Mr.Stevens, Division of Minerals 6 Geology As per your faxed letter of February 23, 1999, I would submit the following as answers to your questions and statements regazding the permit application: PAGE 1: The Location of the pit is in the NW of the SW '/. of Section 27 EXHIBIT C, Section (e) The floor of the pit will be approximately 10 below the present elevation of the ground.

Once the material has been placed into a ridge by the bulldozer afront-end loader will scoop up the roaterial and deposit it oo the conveyor. The mining will be carried oo in a semi-wet pit with no de-watering occurring. EXHIBIT C, Section (i) The well permit application has been made to the State Engineer to allow for the water which will be carried off-site with the processed sand product. The exposure of the ground water will be temporary, only during the mining process. The mined area of the pit will be filled to above the ground water table during the reclamation process. The resulting mined area will not have any ground water exposed therefore no evaporative loss after mining is completed. The approximate amount of water to be contained io the product after processing is 4%. 90,000 tons would contain 7,200,000 pounds of water( 867,470 gallons =2.66 acre feet). The well permit application calls for 20 acre feet which is more then
