EXHIBIT "D" <br />• MINING PLAN INFORMATION <br />(a) Description of the methods of mining in each stage of <br />operation as related to surface disturbances: <br />Mining methods will Lie consistent throughout the life of this <br />operation. The area to be mined lies in the High Plains Area of <br />the Arkansas River Valley between Fatterson Hollow and Timpas <br />Creek_ The pit is located on a high terrace lying from 150 to 200 <br />feet above the adjacent stream valleys and is generally. underlain <br />by gravelly alluvial materials deposited by these streams in <br />anr_ient times. The existing overburden of these deposits are of <br />such composition that it makes excellent binding material for the <br />County's road base material. Top soil therefore will be hauled in <br />from the yearly borrow Fit cleaning performed by the County. A <br />substantial amount of top soil has already been hauled and stock <br />piled on the site. <br />A 50 foot set back will be maintained from the overhead power line <br />on the south perimeter of the requested permit area. <br />(b) Earth Moving: <br />The earthmoving equipment used on the site will consist of front <br />end loaders, dozex•s, scrapers, blades ox' any combination thereof. <br />• (c) Water Diversions and Improvements: <br />The Hancock Fit has no water sources available and is not expected <br />to affect any surface or subsurface water during mining operation. <br />[Jo water will be used or is ne~,essary for this operation. <br />(d) Size of the area to be worked at any one time: <br />A maximum of 20 acres will be disturbed at any one time and will <br />consist of mining, processing and stock piling materials. <br />(e) An approximate time table to described the mining operation <br />and the relation between mining and reclamation: <br />The existing 112 F'erniit. for Hancock Fit was issued in 1982 fur a <br />total of 30 acres. This acreage included 12.3 acres that was mined <br />prior to permitting. In discussions with Road and Bridge personnel <br />it is estimated the 12.3 acre tract was mined approximately ten <br />years prior to permitting the area. A total of approximately <br />twenty five years of mining activity has occurred at this site. <br />The County is requesting an amendment. for E`l additional acres at <br />the Hancock Fit site. It is estimated the additional acreage would <br />fulfill the County"s needs for roai} materials for 25 to 30 years. <br />(i) An estimate of the periods of time which will be required for <br />• the various stages or phases of operation: <br />F'age 1 <br />
