Mike Long <br />Page 15 <br />Backfilline of Hiehwalls <br />Further, as discussed in 2.05.3 and 2.05.4, all highwalls <br />will be backfilled and compacted and the area will be <br />graded to conform to the proposed post-mining land uses <br />of irrigated pasture and range land. There will be a <br />slight departure from the approximate original contour <br />in that the upper portions of the surface mined area <br />will be reclaimed to a gently rolling mesa. Departure <br />from the approximate original contour is discussed in <br />2.06.5 <br />Hiehwall Disturbance <br />Land above the highwall will be disturbed in that each <br />successive highwall designates the northernmost limit <br />of each mining area (see 2.05.3 and the Mine Plan Map <br />(Map 12). The final highwall will be backfilled and <br />the area reclaimed in accordance with 2.05.3 and 2.05.4 <br />of the permit application. <br />Excess Overburden <br />Excess overburden will not be realized as a result of <br />the proposed surface mining operations. The overburden <br />balance calculations are presented in Exhibit 33 as an <br />attachment to the permit application. As described by <br />those calculations, the proposed post-mining topography <br />depicted on Maps 10 and 11 will be attained through the <br />proper backfilling of all spoil material. <br />Woody Materials <br />As stated in 2.05.3, larger woody materials are pushed <br />into piles for use as firewood while the smaller brush <br />piles are disposed of. If in-pit deposition of these <br />materials occurs, it should not affect the stability of <br />backfilled areas in that those materials removed from <br />the last period of mining will not be placed below the <br />final highwall in such a manner as to affect the stability <br />of the backfilled area. The backfilled material at the <br />final highwall will be keyed to the undisturbed topography <br />bordering the final mining area. Therefore, stability <br />problems as a result of disposal of the material should <br />not result. <br />
