dependent upon factors such as pit configurations, excavator performance, and customer
demand. Amore detailed discussion of the operational methods is presented in Tab 12. In
order to achieve the designed postmining landform, the necessary 6ac kfill material must 6e
available to perform area grading on internal spoil. Generally, adequate material will
not be available until excavaCion has developetl two spoil.. Tab 12 discusses the area
grading concept. When the pit configuration is regular (e.!)., typically, interior spoil),
and where sufficient area is available to perform "area !)r:3ding", Peabody will maintain
backfilling and grading within two spoil rows.
Four spoil peaks will also be created by other mining situations. It could take four
spoil rows to create sufficient spoil area to allow final, grading to "daylight" and blend
into the surrounding topography. Ramps, roads, or facilities must no Longer be required
for the mining operation before they can be removed or relocated and the adjacent spoil
excavaCed to final grade. Lastly, the completion of t~ac kfilling and grading of final
highwalls may require uD to two years following coal removal. This is due to the larger
operational area required for highwall reduction as opposed to interior spoil grading.

depicted on Exhibit 13-2. Peabody proposes to utilize the bar kfilling and grading
sequence proposed on Exhibit 13-2 and the general reelamal:ion schedule presented here to
achieve the proposed postmining topography on Exhibit 12-9.
Soil replacement will be completed within one year following final grading provided the
area is not being used for facility or monitoring related activities (i.e., items such as,
but not limited to ramps, deadhead routes, light use roads, haul roads, ponds, drainages,
diversions, boneyards, office, or shop areas). tf final grade is achieved during fall or
winter months, Soil will be redistributed the following :summer or fall to accomrnodete fall
seeding. llh en final grade is accomplished during spring or summer months, soil will be
redistributed by fall to accommodate fall seeding.
Detailed discussions of actions ere found in Tabs 9, 12, and 13.
