• Stockpile locations are shown on Figure 4.4-3. After topsoil is
removed from the individual sites, the areas are also vegetated.
4.4.2.3 Grading and Site Preparation
The terraces, designated as Employee Parking, Lay Down Yard,
Coal Storage Pile, Auxiliary Facility Building, General
Processing Building, Temporary Mining Refuse Storage and Extra
Lay Down Yard were retained as constructed. These terraces are
on three different levels. The Auxiliary Facilities Building
and General Processing Building were on the upper terrace. The
Employee Parking, Lay Down Yard and Coal Storage Pile were on
the middle level. The Extra Lay Down Yard and Temporary Mining
Refuse Storage were on the lower level. The size of the
terraces are as follows (see Figure 4.6-4):
The upper terrace is approximately 1,000 feet in
length with an average width of 60 feet (105 feet at
the widest point).
The middle terrace is approximately 1,400 feet in
length with an average width of 90 feet (105 feet at
the widest point).
The lower terrace is approximately 1,400 feet in
• length with an average width of 60 feet (80 feet at
the widest point).
The outslopes of these terraces have previously been vegetated
and have, although only partially covered with topsoil, well
established grass and woody species growth. Sagebrush on these
slopes are over 3 feet tall and grasses have grown to almost the
same height. For the 10 years of existence, the slopes have
been stable and no failure or sloughing has ever occurred,
except as explained below (see Exhibit 4.7-5). The slopes are
from lh:lv to 2.5h:ly with and average of 1.5h:ly. Slopes are
very difficult to vegetate and, due to the presently well
established plant growth, they were retained in their present
condition except as noted below. The terraces were retained in
their present size because the large flat areas are beneficial
to the postminig land use. The flat terraces will also better
retain water from precipitation which will enhance plant growth.
Unless physically retained, other areas downhill from the portal
benches and portal access roads were graded to 3h:ly or lesser
slopes. For additional support of the program see the letter
from the Division of Wildlife in Exhibit 4.8-1.
The middle terrace experienced one small area of instability
after it was reclaimed. The grading work associated with the
reclamation apparently allowed water to collect in one area
. which caused the slope to become saturated and slough. The
