1 <br />' Laramie and the reds are obtained from the Upper Laramie. These <br />are the clays the operator generally uses for brick production. <br />Clays to be mined lie in strata that dip 70 to SO degrees to <br />' the east. The strata are interbedded with sand. Approximately 40 <br />' percent of the materiel to be mined is expected to produce waste <br />sand. The sands used at the brick plants generally are taken from <br />' the Fox Hills Sandstone Formation because of their better <br />quality. <br />' West <br />surface coal beds <br />' ~ ~ ~ S clays on beds East <br />urFace <br />'.~. •.: <br />FOX HILLS '..

An exploration drill hole program <br />' encountered soils and overburden described as varying from zero to <br />five feet of soil and zero to twenty-two feet of overburden. <br />The detailed soils report in Exhibit I, prepared by Mark Heffner, <br />shows six distinguishable soil map units (see Exhibit I for details <br />concerning soils). <br />' As a result of mining activity prior to the Mined Land <br />Reclamation Act and its amendments, and specifically during the <br />' era 1939 to 1976, approximately one-third of the surface area <br />was disturbed and soils were mixed with overburden and <br />1 stockpiled. This prior practice caused a shortage of <br />' soils for reclamation. Since 1976 the operator has saved and will <br />9 <br />
