A soil depth map, Figure 3.2-1, delineates the available depth
of topsoil (inches) for each map unit. The soil depth suitable
for stripping and reclamation use has been determined through
evaluation of topsoil material by horizon as presented in Soils
Assessment, Munger Canyon Permit (WRDC 1980 a).
3.2.2 Volumes of Topsoil Available for Reclamation
The road right of way, mine portal, topsoil stockpiles, and
waste rock disposal area will disturb about 29.2 acres of land
not previously disturbed. The road right of way will affect
18.92 acres, the mine site will affect 6.? acres, the topsoil
roc.K
stockpiles and waste mead disposal area will affect 3.9 acres.
The Volume of topsoil available for reclamation is about 6 acre-
feet (9680 bcy). About 5 acre-feet can be salvaged from the
road expansion and about 1 acre foot from the waste rock area.
Most of the soils will be salvaged along the haul road right of
way. Presently undisturbed soils that will be salvaged along the
road corridor are the Glendive (GdAB), Havre (HrAB and HvAB), Nihill
(NiAB), and Rivra (RiAB) The map units to be salvaged, accepted
areas, depths to be stripped, percentage of unit to be stripped, and
the acre feet are shown in Table 3.3-2. The Soil Assessment-Depth
of Suitable Topsoil (Figure 3.2-1) shows depths to be salvaged along
the road right of way. Much of the area has previously been affected.
No soils will be salvaged from the areas mapped as DL. The east end
of the right of way is in map unit TRDE and slopes are generally too
