The reclamation plan calls for returning the disturbed areas, after mining and reclamation, to a land use
that is "industrial". This land use is consistent with that found in the surrounding area and the underlying
land use zone designation.
The prevalent feature of the reclaimed area will be an 11.0 acre pond that will serve as a visual amenity
for the future uses that will be established on a graveled surfaced area adjacent to River Road.
A Reclamation Plan Map depicting the configuration of the reclaimed ground surface can be found in
Exhibit F.
Reclamation will be conducted in a phased manner and will begin when no further disturbance will occur
as a result of the mining activities in each of the identified phases. In other words, reclamation may
happen during the same time as mining activities are occurring in each phase. It is anticipated that
reclamation efforts will occur on a 12 to 18 month cycle until all mining activities have ceased.
Reclamation will be conducted in a phased manner and will begin when no further disturbance will occur
as a result of the resource extraction activities in a particular area within the identified mining area. In
other words, reclamation may happen during the same time as mining activities are occurring in each
phase. It is anticipated that reclamation efforts will occur on a 12 to 18 month cycle until all mining
activities have ceased.
BACKFILLING AND GRADING -After the resource is removed, backfilling and grading activities will
commence except for any working gravel faces(s). The stockpiled overburden will be hauled from its
storage area adjacent to the mining area by mobile equipment and placed where required to achieve a
level topography and properly backfilled slopes. The side slopes of the resource extraction area will be
re-graded to be no steeper than a ratio of 3:1 (horizontal to vertical). Backfilling and grading will be done
by dozers, andlor, scrapers which will compact and stabilize the overburden material. To insure stability
of the slopes, material will be placed in 12 inch lifts and compacted to a minimum density of 85 percent of
the optimum density.
In the event that material delivered to the facility from outside sources is used in the backfilling and
grading operations, the following procedure will be implemented to insure that the material is clean and
inert:
1. The individual or company, other than the mine operator, delivering material to the facility will be
required to sign an affidavit certifying that the material is: clean and inert, the originating source of
the material, and the estimated volume. At the discretion of the facility operator, the certification
may also include an environmental audit of the source site prepared by a Colorado Registered
Professional Engineer or a Registered Environmental Manager.
2. During the stockpiling process, the facility manager and those individuals who operate the
stockpiling equipment will conduct constant visual analysis of the delivered material on a truck by
truck basis. At a minimum, the visual evaluation will identify that the soil does not have any
hydrocarbon contamination, hazardous substances, or other solid waste.
3. In the event that contaminated material is identified, all work in the immediate area will cease and
a Colorado Registered Professional Engineer or a Registered Environmental Manager will be
contacted by the facility operator. The qualified individual(s) will prepare, supervise and
implement a Remediation and Disposal Plan conducted in accordance with the requirements of
the governing regulatory agencies.
