III. COMMENTS - COMPLIANCE
Below are comments on the inspection. The comments include discussion of observations made during the
inspection. Comments also describe any enforcement actions taken during the inspection and the facts or
evidence supporting the enforcement action.
This was a partial inspection conducted by Janet Binns of Colorado Division of Reclamation, Mining, and
Safety. Graham Roberts of Trapper Mining Inc. (TMI), accompanied the inspection and represented the
operator. The mine is an active surface mine with three active pits; Z pit, F pit, and D pit. Both Z pit an F pit
are approaching their final cuts. TMI is in the process of permitting mining of the K pit and construction of an
excess spoil fill in the upper portions of Horse Gulch. The weather was warm and clear in the morning.
Clouding up in the afternoon with virga visible at the upper ridgeline as the afternoon progressed. Mine site is
dry and only received .02 inches of precipitation the preceding day from isolated showers.
Roads: Haul roads were dry during the inspection but the LOM Haul road was being watered with a water truck
from the warehouse to the north end of F pit at the time of the inspection. Fugitive dust off the roads was not
observed during the inspection. The haulroad along the west side of the slide has been repaired and is being
utilized in the topsoil stripping operation.
Topsoil: The operator was in the process of stripping Topsoil from the southern end of the slide area. This soil
was being hauled by truck from the slide area to the northwest side of F pit. The topsoil will be redistributed on
regarded slopes from this point. Not all of the topsoil on the slide is recoverable. Some portions of the slide
block had mixing of the topsoil resource and underlying material. TMI is only salvaging the topsoil that
remains uncontaminated by large rocks or heavy subsoil. TMI is awaiting approval of a TR that is currently
under review by the Division, to initiate additional topsoil stripping in the bottom of Horse gulch drainage.
TMI has previously stripped the southern end of Horse gulch drainage to start construction of a Spoil fill
underdrain.
Topsoil stockpiles have appropriate topsoil markers clearly visible. .The topsoil stock pile marker consists of a
post topped with white PVC with a large black "T"painted on it.
Explosives: A parting blast was detonated at the southern end of F pit around Ipm. Blast warnings and radio
warnings were conducted in accordance with the permitted blasting procedures prior to and following the blast.
Back fill & Grading: TMI had constructed a"finger drain" as a portion of the Horse gulch spoil fill underdrain.
A dozer was in the process of covering this "finger drain"with spoil material and burying it. The west side of F
pit spoils had been pushed down and will be graded to final contours prior to topsoil placement.
Excess spoil: As mentioned in prior paragraphs of this report, TMI has started preparation work for the Horse
Gulch spoil fill. Topsoil stripping in order to construct the underdrain trench and place rock for the trench has
begun. Covering of the underdrain "finger drain" was underway. No placement of spoil material in the gulch
bottom has occurred.
