Marcia Talvitie Township 46 North, Section 32: Section 33: Township 45 North, Section 4: Section 5: -2- Range 15 West. N.M.P.M. E /2E/2 W /2, Disturbed areas in the S/2NW /4NE /4, SE/4NE/4, W /2NW /4SE /4 Range 15 West, N.M.P.M. Portions of Lots 3, 4, 5, 6, 11 & 12 N /2NE/4NE/4 January 3, 2012 14. A Map Showing Area: Figure 1 is enclosed. 15. Dates Reclamation Work Performed: Third and fourth quarters of 1993 with supplemental seeding performed in 1995 and 1998. Sediment Pond A and the associated ditch were reclaimed in late 2010. 16. A description of results achieved: Mining operations commenced at the Hamilton Mine in March 1992 and ceased in July 1993. During the third and fourth quarters of 1993 the mine site was reclaimed. All equipment and facilities were removed from the mine site. The mine site was regraded to approximate original contour, topsoil was replaced on the regraded areas and the mine site was seeded and mulched. Reclamation efforts were completed in December 1993. Supplemental seeding was performed in 1995 and 1998. Sediment Pond A and the associated ditch were reclaimed in late 2010. Vegetation has become well established during the ensuing years. The enclosed vegetation studies performed in July 2010 and August 2011, shows the reclaimed mine site has better plant cover than the undisturbed adjacent areas and the reference areas. The Vegetation report documents revegetation success criteria, as required by Rule 4.15.8, have been achieved for the last two consecutive years. As discussed in the Findings of Compliance document for Phase II Bond Release, 'Honeywood has established vegetation which supports the approved post mine land use of improved rangeland and wildlife habitat and meets the approved success standard for vegetative cover'. Since the July 2010 survey was used in part for the Phase II bond release, and the August 2011 vegetation survey demonstrated similar results, the reclaimed mine site meets the approved success standard for cover and supports the approved postmining land use of rangeland and wildlife habitat. All reclamation work has been performed in accordance with plans approved by the Division of Reclamation Mining and Safety. A soil loss demonstration for the reclaimed area was incorporated into the permit with the approval of TR -10 and MR -11 in 2009. The calculations demonstrate that untreated drainage from the reclaimed area will contribute fewer suspended solids to streamflow or runoff outside the permit area than will untreated drainage from the natural surrounding area. The reduction in suspended solids determination is consistent with the permit document which states 'the surface coal mining operation is not expected to result in the contamination, diminution, or interruption of underground or surface water'. Review of annual hydrologic reports demonstrate there is no evidence of groundwater contamination. Based on geology in the area, the surface mining operation was unlikely to affect groundwater as the potentiometric surface of the groundwater is approximately 100 feet below the lowest coal seam that could have been mined, and impermeable layers of shale totaling about 20 -feet thick exist between the lowest coal seam that could have been
