The reclamation plan calls for retummg the disturbed areas. arnar n,inuxl and reclamation, to a land use
that is 'rangeland' This land use is conststent wdh that found m Ih~• surrounding area and the underlying
land use zone desrgnalion.
The prevalent feature of the reclaimed area will be an 11.0 acre pond. A Reclamation Plan Map depicting
the configuration of the rectaimed ground surlaco can be found m Exhibd F A timetable outlining a
description of the reclamation eRorts can be found within Exhibd D
Redamation will be conducted in a phased manner and will begin when no further disturbance will occur
as a result of the mlNng activiies In other words, redamation may happen during the same time as
mining activities are occumng. It is anticipated that redamation efforts Mnll occur on a 12 to 18 month
cycle until all mining activities have ceased.
BACKFILLING AND GRADING - ARer the resource is removed. backfilling and grading activdies will
commenco except for any working gravel faces(s). The stockpiled overbuNen will be hauled Irom ds
storage area adjacent to the mining area by mobile egwpment and placed where required to achieve a
level topography and properly backlilled slopes. The side slopes of the resource extraction area will be
re-gradetl to be no sleeper Then a ratio of 3 1 (horizontal to vertrcat) BackfilNng arW grading will be done
by dozers, and/or, scrapers which will compact and stabilize the overburden matenal. To insure stability
of the slopes. matenal will be placed m 12 inch tilts artd compacted to a minimum density of 85 percent of
the optimum density.
In ilia even) that material delivered to the IaGlity Irom outsWe sources is used in the backfilling and
grading operations, the following procedure will be implemented to insure that the matenal is clean and
ineA
1. The individual or company, other Ihan the mine operator. delivering material to the laahty well be
requred to sign an affidavd certifying that the matenal is: Gean and inert. the originating source of
the matenal, and the estimated volume At the discretion of the ladlity operator, the cenlbcation
may also inctude 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 lauldy manager and those mdrvrduals who operate the
stockpiling egwpment will conduct constant visual analysis of the delivered material on a buck by
truck bass At a minimum, the visual evaluation will identify that the soil does not have any
hydrocarbon contamination, hazardous substances. or other solo waste.
3. In the event that contaminated matenal is identified, all work in the immediate area will cease and
a Colorado Registered Professianal Engineer or a Registered Environmental Manager will be
tentacled by the fauhty operator Tha qualified individual(s) will prepare, supernse and
implement a Remedralion and Disposal Plan conducted in accordance with the requirements of
the governing regulatory agencies.
TOPSOIL REPLACEMENT -Topsoil replacemem N~II occur using loaders. trucks and a blade. once alt
re-grading of the area disturbed by mining in each phase is complete. Efforts unit be undertaken to
minimize compacbon of the topsoil and soil structure degradation Such as, avoidance of repeated
driving wdh egwpment over the same area once the soil has been placed. Topsoil Nell be replaced to a
Thickness of at least 8 inches, which Is appropriate to estabUSh vegetabon communilies consistent wdh
the post mine land use.
