.. ~, <br />Irrespective of these possible areal changes, regrading activities will establish <br />approximately the contours shown on Map M12 even though the actual regraded areas <br />may not coincide exactly with the areas shown on the map. <br />The majority of areas at Trapper Mine that have been mined or will be mined are <br />on the north slope of Che Williams Fork Mountains. As demonstrated by the post- <br />mining topography map, mining and subsequent regrading operations will not affect <br />the overall slope of the land. The final postmining graded slopes will not be <br />uniform, but they wi21 approximate the general nature of the premining topo- <br />graphy. The final slopes will not be steeper than the premining slopes in any <br />general area, and they will be graded to the mast moderate and favorable gradi- <br />ents practicable Co promote stability and effective revegetation. <br /> On occasion, in order to maximize coal recovery, overburden may be removed by <br /> other than draglines. The material will be placed on mined-out ar eas or at the <br /> ends of a cut on areas which have been stripped of topsoil, but not otherwise <br /> disturbed. Once the m ining operation necessary for coal removal is complete, <br /> these spoil piles will be handled in such a fashion that they Mead into and com- <br />• element the surrounding pos[mine topography. <br />Regrading will continue to be perfo rn <br />men[ with occasional assistance From <br />steeper than one vertical to three <br />areas where the original slopes were <br />essary in these instances. <br />led predominantly by dozers or similar equip- <br />the draglines.
