Findings and observations <br />The Team evaluated the following parcels for post -mining topography, surface stability, and <br />drainage control: <br />• F -A-16 (3.7 ac.) <br />• K -A-16 (32.9 ac.) <br />• Z -A-14 (2.0 ac.) <br />• Z -A-15 (26.9 ac.) <br />• Z -A-16 (88.4 ac.) <br />• A -B-09 (0.3 ac.) <br />• A -B-14 (2.7 ac.) <br />• A -B-16 (18.4 ac.) <br />To verify backfill to approximate original contour, DRMS collects GPS -generated elevation <br />readings along randomly generated transects in each reclaimed parcel. The Team collected a total <br />of 38 elevation points for comparison against pre -mining topography data. The Team also took <br />measurements for gradient using a manual clinometer; the slopes of the reclaimed parcels ranged <br />from 1° to 30°. <br />Overall, surface stability was very good. Volunteer annual and seeded perennial vegetation was <br />sufficiently established to control erosion. Reconstructed stream channels featured check dams in <br />steep areas to reduce hydrologic velocity. All highwall had been eliminated, and no settling, <br />slumping, slides, scarps, or other major instability of the backfilled overburden and topsoil was <br />noted. See Figure 1. <br />Limited erosional features caught the attention of the Team. Specifically: <br />• Rilling at previously repaired reclaimed parcel Z -A-16. See Figure 2. <br />• Headcutting within the Z -A-16 reconstructed drainage channel (east fork). See Figure 3 <br />• Minor headcutting within the Z -A-16 reconstructed drainage channel (west fork). See <br />Figure 4. <br />Mr. Roberts agreed to monitor and/or repair these areas of concern as appropriate. The Division <br />inspector plans to follow up during the next regularly scheduled minesite inspection. <br />Conclusion and recommendations <br />The Phase I reclamation evaluated during this inspection comports with the terms of the Trapper <br />permit, the approved Colorado regulatory program, and supports the post mining land use of <br />rangeland. Contingent on the Division's satisfactory followup inspection of the three repair items <br />noted above, I recommend Phase I release for all 175.3 acres of reclamation evaluated this day. <br />C.
