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 of the Hamilton Mine conducted by Marcia Talvitie of the Colorado
DRMS on Wednesday, 23 July 2008. No representative of the operator was present during the
inspection.
Mans and Markers
Mine and permit identification signs were displayed at the County Road access, in accordance
with Section 4.02.2.
Roads
The roads were dry and passable throughout the permit area.
Hydrologic Balance
Roadside ditch bottoms were damp, giving evidence of recent rainfall.
Pond A was completely dry, and the spillway showed no signs of recent discharge. Cobble
riprap has slid away from the black spillway liner in several spots, exposing the liner to sunlight
(Figure 1). The liner shows little effect of deterioration, but riprap should be adjusted so as to
cover the liner.
Pond B continued to hold water(Figure 2), but the level had dropped since the June inspection,
and there was no evidence of recent discharge.
Topsoil
Topsoil piles were protected by fence and clearly identified with signs.
Fish &Wildlife
A cottontail rabbit and hummingbird were sighted in the vicinity of Pond B, and tracks of deer,
elk and coyote were observed in the mud surrounding the pond.
Revegetation
At Pond A, rubber rabbit brush and Indian Ricegrass were well established on the dam crest.
Yucca was thriving below the spillway (Figure 3).
Reclamation Success
Tamarisk plants continue to thrive along the dam perimeter of Ponds A and B. Whitetop is
somewhat plentiful around Pond A,
Russian Knapweed was becoming established at numerous locations throughout the permit
area. Several plants are clustered immediately southwest of Pond A, next to the fence, and
other colonies were observed along the main access road and inside the western fence at
Mining Area 1 (Figure 4).
A copy of the Weed Control Plan from the Hamilton Mine Permit Application [pp 2.05-25 and
2.05-25(i)] is attached for reference. The operator is reminded to be diligent in holding to the
tenets of its Weed Control Plan, particularly with respect to the weeds observed during the
inspection.
