n t <br />• <br />III. COMMENTS -COMPLIANCE <br />Below are comments on the inspection. The comments include discussion of observations made during <br />the inspection. Comments also describe any enforcement actions taken during the inspection and the <br />facts or evidence supporting the enforcement action. <br />This partial inspection of the La Plata No. 1 Mine was conducted by Wally Erickson from <br />the DMG field office in Durango, 484 Turner Drive, Building F, Suite 101, Durango, CO <br />81301, phone (970) 247-5193. The permit for the La Plata No. 1 Mine has been <br />revoked. Final reclamation was assured by Rocky Mountain Bank & Trust, therefore, <br />financial warranty was not forfeited. On 4/25/96, DMG conducted Phase I & II bond <br />release inspection. No activity was observed at the mine site during the time of this <br />inspection. DMG inspector did not contact anyone at the mine site. <br />Public access is controlled by gate at the entrance, gate was open. Erosion on access <br />road, identified in previous DMG inspection reports, had been repaired. Erosion repairs <br />appeared to include the following: gullies backfilled; construction of series of small <br />water bars; and reseeding area. <br />Backfilled and graded areas appeared stable, reclaimed areas blended with natural <br />topography. Vegetative cover for reclaimed slopes appeared diverse and well <br />established. <br />Uncontrolled drainage has eroded the steep slope, located above the mine shop <br />structures arid below the reclaimed slope. Resulting erosion has undercut geocell <br />channel liner, gully is approximately 2' deep and 3' wide. Capacity of sediment <br />retention basin, located at base of steep slope, has been consumed. Maintenance of <br />sediment retention basin is required to restore capacity and function of basin. Erosion <br />resistant lining is necessary for eroded drainage channel. Repair of eroded slope to <br />stable configuration is required. <br />
