study to assess the global stability of the proposed spoil pile west of the pit and came to the conclusion that <br />overall, a combined review of the numerical modeling results indicate that the proposed spoil pile is likely <br />to be stable over its projected life of 4 – 6 years. <br /> <br />The backfilled pit is graded to approximate the pre-mined contour and blended in with the surrounding <br />topography. Final grading is performed along the contour except where the safety of men and equipment <br />may be compromised. <br /> <br />The area is then prepared for topsoil replacement. A dozer pulling a drag, or similarly effective equipment, <br />may be used for areas being reclaimed to cropland. The drag levels ridges made during recontouring to <br />allow a more uniform depth of topsoil to be laid down. <br /> <br />The topsoil is placed on the graded spoil to a predetermined depth as uniformly as is practicable. <br />Fertilization (croplands only) and seedbed preparations follow. The areas are then seeded. (Sections 3.5 <br />and 3.6 discuss these reclamation operations in more detail.) <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br />3-15d
