TAB 16
BACKFILLING AND GRADING
Introduction
The loadout area was originally disturbed by construction activities during the time
period 1976 - 1979. The majority of the earthmoving operations were conducted as a direct
result of the grade requirements for the railroad spur and loop. The topography of the
land prior to construction was such that construction of the spur required much more cut
than it did fill. The following discussion regarding backfilling and grading is limited
to those areas disturbed due to construction and will be backfilled and graded only when
the loadout is no longer needed.
Timing of Bac kfilling and Grading
The loadout area and railroad spur will be backfilled and graded in conjunction with
closure or final reclamation of the facility. RGTI is unable to estimate a tentative data
for backfilling and grading because the life-of-facility has not yet been determined (see
Tab 17, Reclamation Schedule).
Method for Rackfilling and Grading
To the extent possible, most backfilling and grading will be Conducted by doting material
into the cut areas. Scrapers will be used for longer distances. Swales will be left in
the cut areas to provide positive drainage (see Exhibit 18 -1). This is not inconsistent
with the post mine Iand use of pasture land. Leaving an undulating topography will also
be of benefit to wildlife as escape and thermal cover. Please refer to Exhibit 18-2 for
pre- and post-operational cross sections.
Disturbance beyond the existing disturbance boundary to backfill or slope certain areas to
an acceptable grade (shallower than 3h:ly) may be necessary. Prior to any new
disturbance, if topsoil exists in this area, it will be salvaged prior to the additional
disturbance. Depending on the location, the topsoil may be pushed back out of the way or
picked up and stockpiled or redistributed.

Coal fines (and/or coal/dirt mixtures) generated during the railcar unloading/truck
haulage operation will be disposed of in the cut areas. The coal fines will be covered
