August 15,2013 C-1981-010/Trapper Mine JLE
GENERAL MINE PLAN COMPLIANCE:
The Baby Doe dragline was down for maintenance. The Queen Anne was actively mining the K-Strike Pit and the
Molly Brown was mining in L-Pit. The truck and loader crew was operating at the time of the inspection. Trapper
was actively backfilling behind the active pits at the time of the inspection.
RECLAMATION SUCCESS-Rule 4.15,Rule 3:
As indicated above,this inspection was conducted to evaluate the 424.2 acre bond release block for phase I bond
release. In accordance with Rule 3.03.1 (2)(a),for phase I bond release,up to sixty percent of the applicable bond
amount shall be released when the permittee successfully completes backfilling,re-grading and drainage control in
accordance with the approved reclamation plan.
Each of these parcels are part of a larger watersheds and each drain into an approve sediment control system.
Drainages have been reconstructed within several of the parcels requested for bond release.The Middle Pyeatt
reconstructed drainage is located within bond release parcel A-B-10.A portion of Oak Gulch drainage is located in
parcel A-B-09. The side slopes of these drainages are very steep and have eroded significantly. Check dams have
been installed within these drainages and they appear to have helped slow the erosion of these drainages to some
degree but they do not appear to have stabilized. The Division and Trapper are currently evaluating the drainage
reconstruction and stabilization plan approved in the permit as part of Permit Revision No.7. Given these issues,
these reconstructed drainages are not eligible for phase I bond release at this time. A corridor surrounding these
drainages will be removed from the bond release area for future maintenance and stabilization efforts.
It appears a portion of the East Pyeatt drainage is in the process of being constructed between bond release parcels
F-A-12 and Z-A-12. While this channel is not depicted on the 2012 ARR map,This channel has been excavated
and rock has been staged in the channel for check dam construction. A corridor for this channel will also be
excluded from the phase I bond release area.
Overall each of the bond release parcels blends in with the surrounding topography. Each of these parcels was
observed during this inspection and the majority of them we walked across. Symptoms of failures or instabilities
such as slumping were not observed. Each of these parcels have been seeded and vegetation has established
throughout the 2009 through 2011 parcels. Annual vegetation and some perennial vegetation have begun to
establish on the 2012 parcels. Large rills and gully erosion features were not observed. One minor rill near
elevation sample point B along transect 12 in parcel F-AB-09 was noted. This feature will need to be monitored
and possibly repaired. Large swales and depressions were not observed.
TOPSOIL—Rule 4.06;Removal 4.06.2; Substitute Materials 4.06.4(4); Storage and Protection 4.06.3;
Redistribution 4.06.4:
At various sample points along the elevation transects,the Division dug topsoil depth test holes with a shovel.
The Division excavated the topsoil until a difference of color or material was reached. The depth of the topsoil
was measured using a 25 foot tape measure. Please see the summary table below for the results:
