South Valora Pit (extends southeast from Pond 0121 • <br />- 2,200 ft of final dragline pit completed in 2003. <br />- Highwall mining scheduled for the latter part of 2004. <br />- Backfilling and grading to be completed in 2005. <br />• "Scraper" Pit and Access (north and east of Pond 014) <br />- 1,400 ft of pit will be left open for coal haulage access to this area. <br />- Approximately 600 ft of final dragline highwall in the eastern portion was completed <br />in 2003. <br />- The western 800 ft of pit area was mined in 2004. <br />- Highwall mining scheduled for 2005. <br />- Backfilling and grading to be completed in 2006 following completion of highwall <br />mining. <br />SCC will utilize the backfilling and grading sequence shown on Exhibit 19-1A, Backfilling and <br />Grading Plan, and the associated reclamation schedule to achieve the postmine topography <br />presented on Exhibit 20-2. <br />A <br />l <br />ti <br />f <br />b <br />t <br />d <br />d <br />b <br />d <br />i <br />F • <br />nnua <br />projec <br />ons <br />or areas <br />e gra <br />o <br />e <br />are <br />ase <br />upon certa <br />n considerations. <br />irst, <br />approximately two spoil rows are normally graded simultaneously once the pit configurations <br />become regular to achieve the desired postmining land configuration and to effectively <br />maintain topographic continuity between grading sequences. Second, the time when grading <br />of specific spoils can begin is based upon excavation cycle times and pit configuration. <br />Rough backfilling and grading will be kept within four spoil ridges and within 180 days, <br />except as discussed above. Cycle times are dependent upon factors such as pit <br />configurations, excavator performance, and customer demand. Third, once grading begins, <br />the number of acres graded annually in a given pit is approximately equal to the number of <br />acres disturbed annually. In certain circumstances, this generalization may not apply <br />because of spoil material needed to achieve the designed postmining landform. For example, <br />the backfilling and grading of box cut spoil, final highwalls, and deep ramps typically require <br />the movement of large volumes of spoil for great distances and may require additional time <br />for final grading after rough backfill and grading has been achieved. Also, certain box cut <br />spoil areas (where box cut material is spoiled on recoverable coal) will be temporarily <br />ungradeable until the recoverable coal is stripped. All of the acres graded in a given year are <br />projected to be topsailed and seeded as soon as possible based on the reclamation timetable, <br />claimed acres in Tabl <br />79-1 <br />ill <br />sent <br />Soil <br />l <br />t <br />ill b <br />l <br />ithi <br />d <br />t <br />d • <br />an <br />repre <br />re <br />e <br />. <br />rep <br />acemen <br />w <br />w <br />w <br />e comp <br />e <br />e <br />n <br />one year following final grading, provided the area is <br />TR-25 6 Revised 09/04 <br />
