.. ~. <br />Irrespective of these possible areal changes, regrading activities will establish ~' <br />approximately the contouzs shown on Map M12 evett 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 the Williams Pork Mountains. As demonstrated by the post- <br />mining topography map, mining attd 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 will 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 most moderate and favorable gradi- <br />ents Qracticahle to 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 an areas which have been stripped of Copsoilr but not otherwise <br /> disturbed. dace the m ining operation necessary for coal removal is compleCe, <br /> these spoil piles will be handled in such a fashion Ghat they blend into and com- <br />• <br />plement the Surrounding <br />postmine [opagraphy. <br />Regrading will continue to be perfo rn <br />ment with occasional assistance from <br />steeper than one vertical to three <br />areas where [he original slopes were <br />essary in these instances. <br />led predominantly by dozer.; of similar equip- <br />the drag2ioes.

Moreover, the final regraded topography blends into the <br />surrounding natural ground. <br />An .important aspect of regrading activities that complements spoil stabilization <br />is the re-establishment of drainage patterns similar to Chose before mining with <br />u~vrsraN ~ <br />3-~2 APB/~~~7 <br />DA?~ <br />~no-Tz~zH. <br />~~:S..~q <br />
