ROCKY MOUNTAIN MATERIALS
EXHIBIT E: Reclamation Plan
1. LAND USE-The Reclamation Plan has been designed to return the mining area back to range
land Reclamation will be completed in phases leaving less than forty-five acres of disturbed land
open at any one time.The Mining Plan will disturb approximately two hundred acres within the
confines of the proposed operation.With reclamation of the site,the range potential should be
improved from the pre-mining condition.The existing gravel slopes retain very little moisture and
therefore sustain very little growth.Pit slopes will be graded to blend into the natural topography
of the area The land use of the pit area is generally rangeland
Q. RECLAMATION PERFORMANCE STANDARDS-The Mining and Reclamation Plans have
been designed to start concurrent reclamation of the pit before completion of Phase I operations
and then continue systematically throughout the life of the pit A stage plan for mining and
reclamation of Phase I mining is shown on Exhibits C and F.Approximate areas and sequence of
reclamation is shown on the Reclamation Plan Map.The stage plan for the other Mining Phases
will be similar to that shown on the sketch. When practical,topsoil will be stripped from the new
stage and used for concurrent reclamation on the stage just completed Topsoil and overburden
stripped for the plait site,access and haul roads will be stockpiled and saved for final reclamation.
In areas where the overburden is over three feet thick,the topsoil will be temporarily stockpiled
until needed.Mine slopes will generally be excavated to a 1:1 slope. In some areas,excess fine
material will be deposited at the toe of the slope,then covered with overburden to produce a slope
of 3:1 or flatter. In other areas,the slopes will simply be graded and topsoil placed to achieve a 3:1
slope. Areas of the mine floor not needed for continued operations will be reclaimed with
• overburden,excess fines and topsoil.At floor edges adjacent to steep slopes,a berm will be
provided to prevent erosion of the slopes or reclaimed area It is anticipated that the reclaimed
mine floor will be in the one to two percent range. Final slopes will be rounded to blend with the
original ground and the mine floor.
To the most practicable event,final reclamation will be coordinated with the most desirable
season for planting. In this area,seeding from early August to October has produced the best
results.Early Spring seeding may be desirable for some stages of the mine.The final
determination will be made at the appropriate time with due consideration for soil moisture
conditions,weather patterns,etc. In preparation for seeding,final graded slopes will be left in a
roughened condition from the grousers of a dozer. Soil in the mined areas will be scarified and
harrowed prior to seeding.To the extent possible,topsoil will be placed at moisture contents
below optimum to prevent compaction of the seedbed Traffic will be diverted away from areas
where topsoil has been placed
The proposed seed mixture and application rates plus other details are attached in Exhibit J.
