• the East River Crossing, and the access roads to the West Portal and East Portal permit
boundaries. The West Portal access road is also a recorded right-of--way granted to the Division
of Wildlife for access to theft properties south of the mine property.
These facilities are shown on Map 15 Surface Distnrbance/Post Mining Land Use East
Portal and Map 16 Surface Disturbance/Post Mining Land Use West Portal.
(c) BackfiUing and Grading
Map l7 -Post Mining Topography and Cross Sections, shows the approximate final surface
configuration for the New Elk Mine facilities. Map 17 shows the post mining topography and
cross sections in the West Portal and East Portal areas. These areas are where either benches or
cut slopes exist and will require grading upon final reclamation.
The West Portal, refuse and silo areas shown on cross section A-A', B-B', C-C' and E-E'
respectively, can be graded to match the surroundings with a balance of earth. The West Portal
fan area will require some fill which will consist of demolition debris from the West Portal
Industrial .Building covered with fill material from the slope south of the Industrial Building.
The non toxic cover material required to complete the final reclamation of the Development
Waste pile will come from the East Portal bench area south of the coal lab.
Final grading will be the means by which natural drainages intersecting the disturbed area will
be continued through the area. Map 17 Post Mining Topography and Cross Sections, shows
the drainages that will be established during final grading. Map 13B Post Mining Topography
• Drainage Basins, shows the associated basins that the drainages will handle. Calculated
discharges in theses drainages for the 100-year, 24hour storm event are provided in Exhibit 19,
Hydrologic Bahmce of Surface Runoff. Design criteria for these drainages are also provided
The RDA final configuration is shown on Figure 6 Final CoaSguration, and Fignre 11 Cross
Section A A' Final Confignrstioa As requested by the Division PPLLC commits to obtaining
rite flattest possible grades on those areas which have the potential for flood irrigation.
(d) Topsoil Removal, Storage and Redistribution
Section 2.115.3(3] discusses topsoil removal. Topsoil at the New Elk Mine will be stored in
stockpiles. The location of these stockpiles is shown on Map 11, Surface Facilities and Roads -
East Portal. Topsoil piles wit! be constructed in an oval shape with the top of the pile leveled
A containmern ditch will be constructed around each pile. Topsoil piles will be marked as such
and seeded with the approved rangeland seed mix (Reference Table 26).
Redistribution will be accomplished with scraper and/or front end loaders and haul tnrcks.
Topsoil depths will~range from 4 inches in the East Portal area to 9 inches in the RDA. Areas
will be ripped to a depth of 18 inches prior to topsoil redistribution and harrowing or chiseling
prior to seeding.
