MINING PLAN EXHIBIT D (cont) <br /> place. The new areas have been used for dry land crop production <br /> or rangeland. <br /> Access to the site is via the existing driveway from the East <br /> 74th Avenue to the north and it will be maintained as needed and <br /> will remain when mining is complete. Since the driveway is an <br /> existing private road and will remain when reclamation ends, it <br /> is not included as part of the permit area. <br /> MINING PLAN <br /> The permit area is being expanded from 47 . 57 acres to 107 . 88 <br /> acres to extend the life of the mine and to continue the sand <br /> gravel and borrow material operations for the area. Along the <br /> affected lands/permit line the mining setback will be 25 feet . <br /> The excavation will proceed both north and south from the area <br /> currently mined as a dry alluvial operation. A portion of the <br /> southern end of the existing mine and new south area has sand and <br /> gravel below the alluvial aquifer associated with Kiowa Creek. <br /> It may be feasible to mine this material as a dry source by <br /> placing a sealing liner around it . But until investigations can <br /> be completed as to the feasibility of obtaining replacement water <br /> for that area, then mining will only take place above the ground- <br /> water table . <br /> At anyone time we may have 2 working faces extend across the <br /> property until an exterior limit is reached. MAP EXHIBIT C-1 -MINING <br /> PLANMAP shows how this may look in the near future . There is not <br /> a dedicated Plant Site since processing takes place at the face <br /> being mined and piles of finished product are placed near the <br /> process equipment until it is hauled from the mine. The current <br /> plan calls for having 4 -10 acre Mining Phases, but under this <br /> amendment the phasing is removed and a maximum disturbance <br /> scenario will be used to allow flexibility for the mine to be <br /> developed from both ends of the deposit . The material mined is <br /> damp so no unusual dust control problems exist . <br /> Mining will expand out from the existing partially mined area to <br /> the south and north. Stripping will precede mining so only <br /> enough area is stripped to cover the next 6 to 12 months of <br /> mining. Reclamation will run concurrent with mining to limit the <br /> amount of area disturbed at any time. The maximum disturbed area <br /> will include partially reclaimed area, mined area, partially <br /> 4 <br />
