November 25, 2008. The inspection was conducted in accordance with Section <br />3.03.2(2). The Division's bond release inspection report is on file at its Denver <br />office and is incorporated by reference in this written finding. Kent Gorham <br />represented the Division. The inspection focused on a final evaluation of all <br />reclaimed areas, including erosion and slope stability of the reclaimed lands, and <br />implementation of the post mining land use. As explained in the Division's <br />inspection report, hereby incorporated by reference, field observations support a <br />finding to approve a termination of jurisdiction and liability release. <br />Completion of Evaluation Required by Section 3.03.2(2) <br />The Division has conducted an evaluation of the reclamation work, in accordance <br />with Section 3.03.2(2). This evaluation considered, among other things: the results <br />of inspections and monitoring, the need for further reclamation work, whether <br />pollution of surface or subsurface water is occurring, and the probability of future <br />occurrence of such pollution. The evaluation concluded that all reclamation has been <br />completed in the bond release area, no water pollution is occurring, and there is little <br />potential for future water pollution. Impacts to ground water and surface water are o r <br />described below. 3aS`? 7?pf/gy? ar? cv <br />Ground Water Impacts -?- O f . (- <br />No known data exists to document ground water impacts at this site Due to the <br />small size, shallow mining depth relative to the surrounding topography, and nature . v <br />of the disturbance caused by the Twin Pines No. 2 Mine, any further degradation by \.13 <br />activities at Twin Pines would be negligible. p?' -y <br />Surface Water Impacts \ `01 <br />w <br />Two former sediment ponds remain as permanent impoundments at both the portal ?twiS <br />area and the coal sales yard. Any surface runoff from the two reclaimed areas would <br />be limited to snowmelt or rainfall runoff. Vegetation appears to be successful in <br />stabilizing the soil profile assuming proper land management practices. Should any 5 <br />minor erosion occur, significant sediment treatment capacity remains in the two TcJ\ <br />permanent ponds. Any discharge of water would likely be treated to an equal or <br />better condition as compared to runoff from surrounding and adjacent lands. <br />Findings on Protection of Hydrologic Balance <br />Given the lack of water in general at this site, the Division finds that the Twin Pines <br />No. 2 Mine has minimized disturbance of the hydrologic balance in the mine plan <br />and adjacent areas, and has prevented material damage outside the permit area. The <br />Division also finds that the Twin Pines No. 2 Mine has not caused hydrologic <br />changes that adversely affect the approved post-mining land use in the permit area. <br />13
