• slopes in the box cut area, some of this materiel will be spoiled ahead of the operation III, <br />and rehandled during the next cut. The result is an area on each side of the box cut <br />that will receive spoil materiel during the excavation process, and cannot be final graded <br />until excavation advances away from the box cut area. Further discussion of this <br />situation is presented in Tab 12 and 20. In order to achieve the designed postmining <br />landf orm, the necessary backfill material must be available to perform area grading on <br />internal spoil. Generally, adequate material will not be available until excavation has <br />developed at least two spoils. Tab 20 discusses the area grading concept. Yhen the pit <br />configuration is regular (e.g., typically, interior spoil), and where sufficient area is <br />available to perform "area grading", Seneca will maintain bac kfilling end grading within <br />two spoil rows. Typically, it will take approximately 90 to 120 days to cycle the <br />dragline from one end of the coat field and back during the permit term; however, due to <br />coal market and operation considerations, it is periodically required to also cycle the <br />dregline from the south to the north and back. This could add 60 to 90 days to the <br />dragline cycle before a single spoil row is created. Therefore, due to [he depth of <br />overburden, and configuration and length of the pit, it could take over one year to <br />generate four spoil rows. <br /> <br />Four spoil peaks will also be created by other mining situations. First, in certain <br />locations such as along the ramps and the haul road, in the box cut spoil area, along <br />certain inside or outside curves, along irregular coal recovery areas, areas with short pi[ <br />lengths and adjacent to facilities areas, it could take more than four spoil rows to <br />create sufficient spoil area to allow final grading to "daylight" antl blend into the <br />surrounding topography. Second, in some cases, the box cut spoil material is required to <br />be dozed or hauled forward into the mined area. in this case, the pit progression must <br />move ahead more than four pit widths and the coal must be removed before the spoil can be <br />excavated and graded to its final configuration. Ramps, roads, ar facilities must no <br />longer be required for the mining operation before they can be removed or relocated end <br />the adjacent spoil excavated to final grade. Lastly, the completion of backfilling and <br />grading of final highwalls may require up to two years following coal removal. This is <br />due to the larger operational area required for highwall reduction as opposed to interior <br />spoil grading. <br />If it becomes apparent that contemporaneous reclamation cannot be obtained, a variance <br />• under Rule 4. 14.1(i)(c) will be requested from the Division before the creation of more <br />than four spoil ridges or extension beyond 180 days following coal removal. <br />5 <br />
