This may include highwall areas along the western and eastern affected <br /> land boundary of the permit area in Section 22, along the northern and southern margins of the <br /> affected land boundary in Section 15, and the operating face currently located in the northwest <br /> quarter of the northeast quarter of Section 22 progressing to the north and eventually northeast <br /> into mining Area B. <br /> Backfilling and reclamation activities operate directly south of the 100' active mining zone with <br /> removal of topsoil and subsoil via bulldozer (waste removal cost, not reclamation cost) loading <br /> via excavator into trucks and transporting these materials to disposal areas located immediately <br /> south of the active mining set back along east and west margins of the pit floor, leaving the <br /> central portions of the pit for roads, access,product stockpiles, and drainage. <br /> Assuming an average final reclamation slope of 3.5:1, (i.e., 4:1 on the south facing slopes of the <br /> northern boundary highwall left by mining and 3:1 final slope of north facing slope of the eastern <br /> boundary line demarcated by the highwall left remaining for visual impact control as mandated <br /> by permit conditions), calculations are as follows: <br />
