EXHIBIT E — RECLAMATION PLAN
1.0 INTRODUCTION
This Exhibit describes the plans and processes involved in reclaiming the site and transforming it to its
ultimate post-mining use as rangeland with a groundwater lake as shown on Exhibit F, Sheet F-1.
Reclamation will occur contemporaneously as portions of the permit area are mined. Final reclamation of the
permit area will occur after the cessation of all mining activities. Current use of the permit area is that of
fenced rangeland with a history of being overgrazed. Final use of the permit area is proposed to be rangeland
with a groundwater lake for the benefit of local wildlife. Pursuant to Rule 6.4.5.2.(b), the applicant evaluated
the proposed post-mining land use regarding adopted state and local land use plans for this area and land
uses in the vicinity. The proposed post-mining use as rangeland with an open water pond is compatible and
will fit into the general character of the area.
The affected area of this site is the same as the permit area of this site and contains 75.6 acres, not all of
which will be disturbed and thus require reclamation.The table below provides a summary of intended end
uses within the affected area upon completion of reclamation as proposed on Map F-1.

2.0 GENERAL RECLAMATION PLAN
As detailed in Exhibit D, mining will occur in two phases. Reclamation is discussed below for both phases.
2.1 Phase 1
Phase 1 is divided into Phase 1 North (area north of a drainage easement) and Phase 1 South (area south of
the drainage easement). During Phase 1, the screening berms will be constructed on the site.The plan is for
berms to remain on the site throughout the life of the mine and the berm on the south side that wraps around
to the east edge to remain even after reclamation. Topsoil at the base of both berms will be placed in
windrows at right angles to the slope for stormwater control and erosion protection. Phase 1 North and Phase
1 South will be mined to create broad bowls of 3H:1 V slopes surrounding a flat area.As mining is completed
in Phase 1 North, it will be reclaimed by covering the area with overburden followed by topsoil and seeded
with the seed mix found in Table E-3, below. Final reclamation of Phase 1 North will involve the creation of
rangeland vegetation on dry ground except for the lined augmentation pond that will be in the southwest
corner of Phase 1 North.As mining is completed in Phase 1 South, overburden and topsoil will be placed on
the 3H:1 V slopes outside of the future Phase 2 mining area and the slopes will be revegetated with the seed
mix found in Table E-3. The Phase 2 mining area will not need to be reclaimed as it is anticipated that this
area will be mined out to become a groundwater lake.
The decreed irrigation water rights associated with the site will be used, as necessary,to establish vegetation.
Efforts will be made to not strip any topsoil until it can be directly placed on areas ready for reclamation;
' A 2.9±acre lined augmentation pond is also planned to be situated in this area.
2 Undisturbed area includes wetlands,buffers,and incidental areas within the permit where no disturbance will occur.
