HomeMy WebLinkAbout990395.tiff EXHIBIT I - SOILS INFORMATION
This information follows the requirements as outlined in Section 6.4.9.
1. The applicant shall indicate on a map or by a statement, the general type,thickness and
distribution of soil over the affected land. Such description will address suitability of
topsoil (or other material) for establishment and maintenance of plant growth.
The soils at the site include Aqolls and Aquents, gravelly substratum (3) and Bankard sandy loam
(10), previously described in the January 1994 Amendment to the Permit. The proposed mine
area also includes the Aquolls and Aquents, flooded (4). This nearly level unit is in depressions
in smooth plains and along the bottoms of natural drainageways. It consists of deep, poorly
drained loamy soils. Wetness and the hazard of flooding are the main limitations in farming and
for most other purposes. The Aqolls and Aquents unit is used mainly for rangeland and potential
is good for development of wetland wildlife habitat.
The nature, depth and thickness of the deposit to be mined and the thickness and type of
overburden to be removed is shown on test hole logs included in this section. Test hole locations
are shown on the Existing Conditions Map included in Exhibit C.

EXHIBIT J - VEGETATION INFORMATION
This information follows the requirements as outlined in Section 6.4.10.
1. Describe the following:
a) present vegetation types,which include quantitative estimates of cover and height for
the principle species in each life-form represented (i.e., trees, tall shrubs, low shrubs,
grasses, forbs)
This property is currently managed to produce corn and alfalfa. There are narrow strips of
native grasses and forbs adjacent to the existing irrigation ditches. Crop production on
unmined portions of the amended area may continue if continued irrigation is amenable to
the mining plan.
_ b) the relationship of present vegetation types to soil types, or alternatively this
information may be presented on a map;
A copy of the USGS Soil Conservation District map is attached.
c) estimates of average annual production for hay meadows and croplands, and carrying
capacity for range lands on or in the vicinity of the affected land,if the choice of
reclamation is for range or agriculture.
The reclaimed portion of this property will not be utilized for crop production in the future.
d) The Applicant shall show the relation of the types of vegetation to existing topography
on a map in Exhibit C.
The mining area is currently managed for production of corn and alfalfa. The topography
is flat and slopes slightly to the northeast. An existing lateral of the Rural Ditch distributes
water to the amendment area. Please see Exhibit C for additional information regarding the
topography of the site. The property will be managed to prevent noxious weed growth or
spread through appropriate mowing.

EXHIBIT L - RECLAMATION COST
We have selected the mining phase that includes the largest area that will be disturbed at one time to
calculate the potential reclamation liability for the Division of Minerals and Geology. This will
occur during the beginning of Phase 3. At that point, Phase 1 areas will be in the process of
reclamation, Phase 2 will be mined, Phase 3 will be stripped and ready to be mined. The dewatering
trench will be at its maximum size, the processing area and haul roads will be disturbed, and
shoreline reclamation will be in process for the ponds in Phase 2. It is anticipated that these
disturbances will total approximately 25 acres. Concurrent reclamation will have taken place on the
shoreline for Phases 1 and 2 and the bottom of the pond will begin to fill once dewatering has been
stopped.
