Section 2.05.4(2)(c) <br />Backfilling and Grading <br />Backfilling and Grading Methods <br />Mining and backfilling operations at New Horizon Mine will be performed concurrently. Scrapers <br />and /or shovel loaded trucks will remove the overburden and parting materials, then haul the <br />material to a previously mined area to be backfilled <br />Along the cropline in the New Horizon 2 area, some box cut overburden material will initially be <br />temporarily stockpiled outside of the area mined (see Map 2.05.3 -1). This box cut material has <br />been stockpiled in a borrow pit near the southeast corner of the permit area and is available for <br />backfilling at the end of mining or at any other time to backfill the mining pit. All vegetative and <br />organic material and topsoil will be removed from the area where overburden material is to be <br />placed. The temporarily stockpiled material will be graded into the mined area and hauled to the <br />final pit area according to the reclamation plan. Map 2.05.4 -1 illustrates the reclaimed land <br />contours for the years 1993 to 2007 as well as the projected reclamation contours for the year <br />2007- 2013. Since scrapers, trucks and dozers will be used, backfilling operations will occur <br />concurrently with mining operations. No draglines will be used. Backfilled material will be placed <br />to minimize effects on post- mining vegetation and ground water, minimize off -site effects and <br />support the approved post- mining land use. Approximately six months will be needed to complete <br />the final backfilling operations in each of the areas mined. <br />Upon completion of the backfilling, all areas disturbed by mining will be graded to a smoothed <br />landform that approximates the existing, pre -mined landform (see Map 2.05.4 -1). <br />This map also has 3 cross sections which show the pre- mining and post- mining land surfaces. <br />(Revised June 2010) 2.05.4(2)(c) -4 <br />
