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 at 691 County Road 233, Suite A 2, Durango, CO 81301, phone [phone]. Five
photos accompany this report. No individuals were contacted and no activities were observed during
the inspection.
Public access to the permit area is controlled by a locked gate at the mine entrance. Previously,
unknown individuals have driven four-wheel drive vehicles around the locked gate. Barriers,
composed of large boulders and/or ditches and earthen berms, were constructed beside the north and
south sides of the entrance road at the gate to discourage unauthorized access to the permit area.
However, unknown individuals continued to drive around the north barrier. The north barrier has been
extended to discourage unauthorized access to the site.
As shown in the photos, Sediment Pond 1 has been backfilled. Topsoil Stockpile 8, previously located
adjacent to the west side of the pond, has been removed. The area previously occupied by Sediment
Pond 1 and Topsoil Stockpile 8 has been graded to blend with the adjacent agricultural field. The
sediment containment ditch, previously routing disturbed area drainage from the south end of the
Equipment Storage Area to Sediment Pond 1, has been backfilled and graded to blend with the
surrounding topography. Approximately 1,300 feet-of a second sediment containment ditch,
previously routing disturbed area drainage from the northern portions of the permit area to Sediment
Pond 1 (East Collection Channel), has been backfilled and graded to blend with the surrounding
topography. Reclamation backfilling and grading of the East Collection Channel terminated at the
second set of triple culverts for an access road to the Mutual Use Area. Backfilled and graded areas
appeared stable, evidence of settling, slumping orexcessive erosion was not observed. Rows were
evident from the grass drill and crimping of the mulch.
As noted above, the lower portion of the East Collection Channel has been reclaimed. The inlet or
mouth of the East Collection Channel has been closed by backfill. Upland drainage and drainage
from the North Pit area is now routed to the Carbon Junction Diversion. However, the remaining
portions of the East Collection Channel, approximately 3,600 feet in length, appeared intact and
capable of collecting drainage from reclaimed lands and concentrating such drainage at the mouth of
the triple culverts.
The embankment for Sediment Pond 2, located at the vest side of the permit area, has been
removed. Earthen material from the removed embankment had been distributed at the base of the
steep slopes immediately north of the pond. The sediment containment ditch, previously routing
affected area drainage to the pond, has been graded to form a bench which traverses the fill slopes
immediately east of the pond.
The North Pit area was not inspected.
