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 La Plata No. 1 Mine was conducted by Wally Erickson from
the DMG Durango office, 484 Turner Drive, Building F, Suite 101, Durango, CO 81301,
phone [phone]. The permit for the La Plata No. 1 Mine has been revoked. Final
reclamation was assured by Rocky Mountain Bank & Trust, therefore, financial warranty
was not forfeited. On 4/25/96, DMG conducted Phase I & II bond release inspection.
No activity was observed at the mine site during the time of this inspection. DMG
inspector did not contact anyone at the mine site.
Public access is controlled by gate at the entrance, gate was open. Erosion repairs on
access road appeared stable, grasses starting to grow on recently redisturbed areas.
Backfilled and graded areas appeared stable, reclaimed areas blended with natural
topography. Vegetative cover for reclaimed slopes appeared diverse and well
established.
Uncontrolled drainage has eroded the steep slope, located above the mine shop
structures and below the reclaimed slope. Resulting erosion has developed gully,
approximately 2' deep and 3' wide, geocell channel lining has been undercut. Capacity
of sediment retention basin, located at base of steep slope, has been consumed.
Maintenance of sediment retention basin is required to restore capacity and function of
basin. Erosion resistant linino is necessary for eroded drainage channel. Repair of
eroded slope to stable configuration is reouired. This erosion problem has been
identified previously in DMG 3/27/97 inspection report.
