(1) All suitable
topsoiling materials, as approved by the department, shall be removed from the
mine site location area before significant disturbance occurs. Removal shall precede each step of the
construction operation. The operator
shall indicate in the reclamation plan the equipment and method used in salvage
(2) Stockpiles of salvaged topsoiling material
shall be located in an area where they will not be disturbed by ongoing construction
operations and will not be lost to wind erosion and surface runoff. All unnecessary compaction and contamination
of the stockpiles shall be eliminated.
Once stockpiled it should not be rehandled until replaced on regraded
disturbances. The department may
require immediate planting of an annual and/or perennial crop on stockpiles for
the purposes of stabilization. Proposed stockpile locations shall be indicated
on the map submitted as part of an application for a permit.
(3) Stockpiled topsoiling materials shall be
replaced on all areas to be seeded within a 90 day period prior to revegetative
seeding or planting. Extreme care shall
be exercised to guard against erosion during application and thereafter. In the case of abandoned roads, the roadbeds
shall be ripped, disced, or otherwise conditioned before topsoil is
replaced. The department may prescribe
additional alternate conditioning methods for the reclamation of abandoned
(4) If necessary, redistributed topsoiling
materials shall be reconditioned by discing, ripping, or other appropriate
methods. Gypsum, lime, fertilizer, or
other amendments may be added in accordance with ARM 17.24.701 through
17.24.703, and/or as stated in the approved reclamation plan.
(5) Regraded surfaces shall be left roughened in
final contour grading to eliminate slippage zones that may develop between
deposited topsoiling materials and heavy textured surfaces. The operator shall take all measures
necessary to assure the stability of topsoil on graded slopes.
