2.05.4 Reclamation Plan RULE 4.27.4 (1) No highwall remnant is proposed. Cliffs above the portals existed prior to mining were not disturbed except to scale unstable portions for safety reasons. Demonstrations that postmining slope stability will exceed a safety factor of 1.3 are contained later in this section. (2) As demonstrated earlier in this section, hydrologic impact will be minimal. (3) As shown on Figure 3.1.2, the land above the highwall will not be disturbed. A small area across the valley from the portals on the cut slope south of the existing mine trailers will have approximately 25 feet of the cut slope crest smoothed to blend in with the compacted fill slope and to improve the postmining slope stability. The additional area to be disturbed will be approximately 0. 15 acres. (4) The landowner request is contained in Appendix K. (5) These operations will comply with all rules and regulations of the DRMS. (6) As was previously approved, spoil from the mine bench area was used in the construction of the haul road when it was built in early 1977. No unique reclamation problems exist that have not been successfully dealt with in similar, semi -arid western coal mining operations. All aspects of the proposed reclamation plan are aimed at achieving the highest possible success in revegetation in consideration of the controlling factors. The reclamation of rangeland will be in those areas where topographic features are commensurate with the historical and proposed use. The blending of rangeland into the steeper sloped wildlife habitat will allow forthe maximum domestic and wildlife uses. POST MINING TOPOGRAPHY Topographic maps depicting approximate reclamation contours are presented in Figure 3.1-1 and 3.1-2. Figure 3.1-1 shows the reclamation plan that was approved for the original permit term with the stipulation that mine bench reclamation be addressed in detail. Figure 3.1-2 depicts the final PR -02 2.05-36- 10/12
