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. acres at Loma Loadout. The portal access road has been successfully reclaimed. The graded backfill slopes in the portal area blend in well and conform to the original topography and there have been no signs of slope instability with this inspection or during previous inspections of the area. All other areas requested for bond release have been restored to the approximate original contour of the pre-mining landscape. Slopes generally are in agreement with approved post-mining contours as shown on the Reclaimed Configuration Maps (Figures 3.1-5 through 3.1-7). The final certification for the waste disposal site was completed and submitted to the DRMS in April 2008. The waste pile and reclaimed topsoil pile are properly reclaimed and stable with no problems noted. Drainages were reconstructed as post-mine features at all of the ephemeral tributaries crossing the portal access area. Surface runoff control appears adequate. Reconstructed drainages throughout the reclamation remain in good condition with maintenance needed on limited areas noted previously in this report. A small area at the base of Post-mine Channel E will require additional riprap and liner repair. There is minor slumping at the former ventilation portal which will require additional backfilling, roughening and reseeding. Numerous silt fences require replacement or repair including along the perimeter of Post-mine Channel H, three silt fences along the edge of the former mine bench near the portals, and one at the reclaimed topsoil pile. The Loma Loadout was in good condition except for the silt fence that needs to be replaced. There are no areas identified as erosionally unstable that would be excluded from this Phase I bond release request. The 1.3 acres associated with the former haul road on BLM land will be eligible for Phase I bond release once the culverts as shown on Figure 2.2-7C, Lower Road Reclamation are removed and low-water crossings/dry fords are properly installed. The silt fence repair and backfill/stabilization of the ventilation portal are maintenance items that will not preclude release from Phase I bond liability. To ensure compliance, the maintenance items identified in this inspection report should be completed as soon as practicable(weather permitting).
