MINING PLAN
they abandoned it and forfeited their bond. The Division. of Minerals and Geology has not
implemented any reclamation because it was hoped that a subsequent operator would permit the
site. Although various parties have leased the land from the Colorado Board of Land
Commissioners, no subsequent permits were pursued. This is the first permit application to be
submitted for this site since it was abandoned.
The fact that the site has been idle for about 15 years or so is actually an advantage from the
point of view of reclamation planning. There has been sufficient time to allow the invasion of
various plant species, including trees and shrubs. This provides an unusually good picture of the
early stages of succession and natural revegetation on this area. That can provide considerable
foundation in the design of both a mining and reclamation plan for the site. These various
conditions are described elsewhere (in the soils and vegetation information).
Mining Plan
Introduction: The mining plan presented here is for Phase 1 only (see Exhibit C-2A). As indicated
elsewhere, Phase 2 is defined in this permit but is not planned. Planning of Phase 2 will require a
permit amendment and no disturbance will be created in Phase 2 until such plan and amendment is
approved.
The mining plan for Phase 1 is divided into two stages (see Exhibit C-213). Stage 1 extends
from the south end of the current quarry excavation northward to the affected land boundary which
is set at 50 feet south of the section 15/22 section line. Stage 1 extends west to the 50' setback from
the quarter section line. The setback from the mesa edge will be from 50' to 100' depending on the
characteristics of the mesa rim as defined below under Setback Characteristics.
Mining will first involve mining the rest of the exposed material (soil already stripped)
which is primarily to the west of the existing quarry. From there northward, land will be stripped
of soil that equals approximately two years worth of mining (about 4 to 7 acres)
Stage 2 is south of stage 1 and may be mined entirely or only in part. Mining of this area
involves very little soil salvage, except in the south end of the stage. In most areas the soil has been
stripped by the previous operator. Part of this soil is stockpiled on the west side of the stage and
will be used for reclamation. Mining in this area, with respect to both depth and lateral extent, will
be defined by the deposit characteristics in this area. At this time it is assumed that the deposit here
is similar to Stage 1. Unfortunately, the deposit depth in this area, especially in the southern �/+ of
Stage 2, is not known and will need to be defined by drilling prior to mining. This thickness needs
to be known so as to avoid exposing underlying formations. Because of the way the mining of
Stage 1 will be conducted, if only a portion of Stage 2 is mined, the final topography created by the
mining will be conceptually the same so as to avoid a need to modify the reclamation plan. It is
possible that only 1k to 'kof Stage 2 will be mined.
Possible Intermittent Activity: Although it is not expected, there is a possibility that this operation
will be active for less than 180 days per year. If such a period were to occur, the site would be
secured to protect, as much as possible, against trespassers and clearly hazardous high walls and
other features adjusted to reduce the hazard. The site would also be inspected at least once a month
to insure that no environmental or safety problems are developing during the period of inactivity. If
the operation remains inactive for a period of 18 months, temporary seeding of areas that present a
potential erosion hazard would be implemented.
