VIII. Coal Processing Waste Banks <br />This operation did not propose a plan to handle coal processing waste as the only <br />processing activity that occurred was is the crushing of coal. Crushing operations did <br />not generate processing waste. <br />No coal processing waste banks have been constructed and no further mining will occur. <br />No specific approvals are required in this section. This mine is in compliance with this <br />section. <br />IX. Coal Processing Waste <br />No coal waste has been generated at this mine. No specific approvals are required in <br />this section. This mine is in compliance with this section. <br />X. Backfilling and Grading <br />The bacld`illing and grading plan has been revised from the original plan as approved in <br />Section 2.05.4 of the permit document. Development of Pit 2 will not occur to the <br />southwest of the Pit 1 as planned. This change in the mine plan required a change in the <br />backfdling and grading plan, as material from Pit 2 would no longer be used to partially <br />backfill Pit 1. The material required to bacid`rll Pit 1 would be obtained from the <br />overburden stockpile next to the pit and from material obtained by reducing the pit <br />highwalls. In this manner, the bottom of the pit was elevated to a grade that allows for <br />drainage of the area. A drainageway was established through the previous pit area to <br />connect with the natural drainage downstream as a part of final grading activities. <br />A total of 448,000 cubic yards of material were backfdled into Pit 1. A volume of <br />284,700 compacted cubic yards were obtained from the overburden stockpile and 163,300 <br />cubic yards from reducing the highwalls next to the pit. The two highwalls, on the east <br />and south of Pit 1, were ripped and graded to 4H:1V to blend these slopes into the <br />surrounding terrain. <br />The dtainageway was constructed at the south end of the pit between the two highwalls. <br />The drainage daylights into an existing channel that ultimately reaches Bolton Draw. The <br />channel is approximately 500 feet long. <br />A sediment pond, Pond No. 2, was constructed in the drainage comdor to control <br />sediment from the southern part of the pit area. All drainage to the north passes through <br />existing sediment Pond No. 1. A temporary drainage diversion ditch was constructed <br />on the west side of the pit to keep undisturbed runoff from entering the reclaimed area. <br />Canadian Strip Mine, C-81-026 24 December 5, 1996 <br />
