Design Criteria
Topic Design Criteria for the Proposed Action
144. Surface will be left roughened ("pocking") as part of the seed bed FS
preparation.
145. Revegetation of all reclaimed areas would include reapplication of
seed (and a Forest Service recommended fertilizer if necessary) and
periodic watering by the operator if revegetation is unsuccessful
within two growing seasons after construction is completed.
146. A seed infix palatable for both wildlife and livestock would be used
for revegetation to support the post-mining land uses.
Reclamation Plan 147. A Reclamation Plan (reviewed by the Forest Service), submitted as DRMS
part of a DRMS mine permit revision, prior to any construction
activities, will include, but not limited to, methods, seeding species
and seeding rates.
COMPLIANCE REQUIREMENTS
SMA Requirements 148. Operator shall comply with applicable requirements of surface 30 CFR
management agency (30 CFR 815.15) or approved State program. 815.15
Plugging 149. Bottom 50-feet of the continuously cored hole would be plugged 30 CFR
Requirements with cementatious grout to prevent water from entering the mine 75.1711
following Deer Creek Shaft Construction.
150. When no longer needed for its intended use each drilled hole or
borehole, wells, or other exposed underground opening shall be
capped, sealed, backfilled, or otherwise properly managed, as
required by the Division and consistent with 30 CFR 75.1711.
Permanent closure measures shall be designed to prevent access to
the mine workings by people, livestock, fish and wildlife,
machinery and to keep acid or other toxic drainage from entering
ground or surface waters.
151. Exploration holes, drill holes or boreholes, wells or other exposed
underground openings not completed to aquifers shall be sealed by
replacing cuttings or other suitable media in the hole and placing a
suitable plug 10 feet below the ground surface to support a cement
plug or other media to within 3 feet of the ground surface. The hole
will be marked.
152. A surface plug shall be placed in accordance with 4.07.3(1) and the
hole shall be marked.
`Canada Lynx Conservation Assessment and Strategy
Developments Associated with Project
Proposal
Constructing an estimated 0.64 miles of road
on private land and drilling and casing of up to
19 MDWs at up to 11 sites on private land.
The effects of these activities are considered in
the effects analyses in Chapter 3. Without the
development on the FS, it is unlikely that these
developments would occur.
