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 125, Durango, CO 81301, phone [phone]. No
activities at the coal mine were observed; no individuals were contacted during the inspection. Ten
photos accompany this report.
As shown in the photos, the area had recently received significant precipitation. Flow debris and
sediment deposition in the Carbon Junction channel indicate flow depths of 18 - 24 inches. Road
drainage, conveyed to the channel by the road side drain ditch, had eroded the straw wattles
previously anchored in the ditch. The twin culverts at the road crossing were clear and functional.
Evidence of significant sediment deposition or flow debris was not observed downstream of the twin
culverts. Evidence of erosion or sediment deposition was not observed at the outlet of the Carbon
Junction channel. Rock lining for all portions of the channel appeared stable and intact.
Other culverts appeared clear with the exception of the double 18-inch culverts located immediately
north of Topsoil Stockpile 7. This set of double culverts conveys drainage from areas recently graded
and topsoil replaced for the coal and immediately adjacent gravel mining permit area. Sediment clean
out of the referenced set of culverts is recommended prior to spring snowmelt season.
Sediment Pond 2, located along the west side of the permit area, was dry. No discharge noted. Pond
embankment appeared well vegetated and stable, no evidence of seeping, slumping or excessive
erosion.
Sediment Pond 1, located at the far southwest corner of the permit area was not inspected.
Vegetative cover for the recently reclaimed North Pit area was well established. Reclaimed slopes
blended nicely with native slopes and appeared stable; evidence of slumping, sliding, or excessive
erosion was not observed. As shown in the attached photos, minor gully development is occurring for
portions of the reclaimed slope. Gully development was interrupted by straw wattle. Evidence of elk
and deer were abundant throughout the reclaimed North Pit area.
