Exhibit E
Reclamation Plan
Post mined land use of all areas except the slopes will be cropland. Finished floor elevation of available
crop area is expected to range from 60 Acres to 70 Acres depending on the depth of the underlying
shale layer in the pit, with slopes at 1% from south to north to facilitate irrigation activities and drainage
with minimal erosion, and access for farm machinery. During mining, available topsoil and overburden
will be stockpiled and stabilized with vegetation, which is expected to range from 0 to 2 feet of
overburden and 0 to 3 inches of topsoil on site. The mining plan does not expect to produce waste
material that will be incorporated in to the pit floor. However, if waste materials from the aggregate
deposit are generated, they will be placed and compacted between the overburden and pit floor, and
graded sufficiently to facilitate farming operations. All materials encountered in mining will be clean
and free of acid producing minerals and other pollutants, therefore no groundwater pollution will occur.
The proposed post mined land use is the current land use, and is consistent with the farming operations
in the area, including the low density of residences in the area. Cropland is relatively quick to establish
and will be completed within S years.
Operations will not affect the hydrologic balance or quality/quantity of the surface or groundwater
operations during mining and reclamation, and will comply with all Colorado and federal water rights
and water law. There are no dredging activities proposed and the operation will not affect any siltation
structures or drainways. Mining activities will be surrounded by small berms to prevent storm water
from the mining and processing area from leaving the site. Sufficient free draining material will remain
and/or be placed under the mining and processing areas to allow storm water to drain through the site,
and will not be impounded typically for more than 24 hours.
Reclamation activities on the south, west, east and part of the north boundary will consist of sloping the
top of the excavation to the pit floor at a 3:1 (3' horizontal x 1' vertical) slope and spreading available
topsoil at a thickness dependent on the amount available. See map title Exhibit F Reclamation Plan Map
for visual details. The slopes will be seeded with a native, drought tolerant grass mix and established
with natural precipitation and possibly irrigation water if needed. The grass mix is as follows:
The pit floor will be reclaimed by spreading available overburden and topsoil at a thickness dependent
on available material, but generally is projected to be a minimum of 2 feet of overburden and topsoil in
a layer of 0-3 inches. The pit floor will then be planted with the next viable crap and irrigated.
