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 partial inspection of the Carbon Junction Coal Mine was conducted by DRMS staff from the
Durango Office, 701 Camino del Rio, Room 315, Durango, CO 81301, phone [phone]. Six
photos accompany this report.
Mine identification sign was posted at the entrance to the permit area. Mine entrance gate was open.
A survey team from Geoff Engineering was surveying lands beyond the northeast end of the North Pit
area. The site was dormant during the inspection, no mining or reclamation activities were occurring.
This inspection focused on the North Pit area, to document the installation of erosion control
structures and re-establishment of the natural drainage patter along the north end of the North Pit
area.
As shown in the photos, at the north end of the North Pit area, reclamation soils overlay native
sandstone cap-rock. Storm drainage from the low permeable cap-rock had previously eroded the
reclaimed lands at the transition of reclaimed lands and native cap-rock. Portions of the transition
area had been recently graded to blend with the natural topography of the cap-rock and to encourage
positive drainage from reclaimed lands. Angular blocks of sandstone had been placed along the
terminus of reclaimed lands to buttress and stabilize reclaimed lands and control erosion. The
recently completed grading and placement of rock armor appears to have re-established the natural
drainage pattern and protect reclaimed lands from erosion.
