W. 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 Wally
Erickson from the DMG Durango Office, 484 Turner Drive, Building F, Suite 101,
Durango, CO 81301, phone [phone]. Jim Hendricks was not located and
therefore not available to accompany the DMG inspector.
Signs & Markers -Mine identification sign was posted at the mine entrance. Public
access is controlled by gate and fence, gate was open. Permit boundary markers were
observed. Topsoil stockpile signs were posted.
Roads -Haul roads and access roads were well maintained. Haul road within permit
area is asphalt surfaced. County road, providing access to the mine entrance, was
also asphalt surfaced. Road side drainage ditches and culverts appeared clear and
functional. Minor sediment was observed in road side drainage ditch immediately
downslope from recently graded and topsoiled rock fill area. Sediment clean-up
appeared to be occurring.
Backfill & Grading of the rock fill area was complete, topsoil replacement had
commenced.
Hydrologic Balance -Evidence of recent precipitation events were observed. Minor
erosion had occurred for recently topsoiled areas.
Sediment pond 1, located at the far south end of the permit area was holding water.
Water depth was visually estimated at 1'. Primary spillway was clear and stable, no
discharge noted. Pond inlets were rock lined and stable. Pond embankments were
well vegetated and stable.
Sediment pond 2, located along the west side of the permit area was holding water.
Water depth was visually estimated at 3'. Primary spillway appeared intact and clear
of sediment and debris, discharge estimated at < 1 gpm and appeared clear.
Secondary spillway was well vegetated and stable, no evidence of recent discharge.
Pond embankment was well vegetated and appeared stable.
Pond 2 inlet ditch -Rock check dams, located in steep sections of the pond inlet ditch,
were intact and stable. Sediment laden waters from the recently graded and topsoiled
rock fill area and conveyed through a road culvert, had deposited sediment within the
pond inlet ditch. Evidence of mild erosion and sedimentation were also observed in
less steep portions of the pond inlet ditch, where rock check dams were absent.
Maintenance of the ditch is necessary to ensure continued function and stability of the
pond inlet ditch. However, during the time of this inspection, the pond inlet ditch
appeared to have sufficient capacity to function as designed.
