t? l <br />?. <br /> <br />Area 3 meets the standard for 1999 and 2000. Therefore, Area 3 has been adequately revegetated, <br />Summary <br />Since the areas requested for bond release are either Pre-Law or re-mined, vegetation standards fall under <br />Rule 4.15.10. Woody plant density standards were not required by the Division. Both reclaimed bond <br />release areas 1 A and 1B exceed the standard of the 1999 and 200o dryland pasture reference areas. Area <br />3 meets the standard for 1999 and 2000. Therefore all three areas are considered adequately revegetated <br />for Phase 1I bond release. <br />PHASE III <br />Surface and ?r©ur?d Wader <br />The surface and groundwater impacts from the New Horizon 1 Kline have been recently evaluated based <br />on discussions with the Division and data gathered over the past 5 years in the reclaimed area. The <br />Probable Hydrologic Consequences section of the permit was revised to incorporate these changes. <br />Qverall, these latest analyses and hydrologic predictions showed no significant groundwater or surface <br />water impacts as a result of mining at this time, nor does there appear to be any likelihood of future <br />impacts. <br />A discussion of the recent evaluation of the impacts is given below. The main impact addressed is the <br />potential for water infiltrating in the spoil and accelerating the degradation of pyrite, subsequently <br />elevating the level of dissolved solids in the spoil groundwater to a much higher degree than the original <br />waters in the overburden. This could then affect surface waters downstream as these spoil waters surface <br />at spring locations. <br />1n support of its original application to mine the Nucla and Nucla East properties know the New Horizon <br />1 and New Horizon 2 mining areas, Peabody Coal Company performed extensive and detailed computer <br />modeling to determine probable hydrologic consequences of mining, Details of the computer modeling <br />are available in Peabody Tab 17. <br />This discussion incorporates water monitoring results through the spring of 2001, which have been <br />valuable in predicting long term probable hydrologic consequences. Duch of the ensuing discussion was <br />taken from the recently modified Section 2.05.?6?3? Protection of the Hydrologic Balance, which includes <br />a detailed discussion on hydrologic consequences. <br />The following discusses potential impacts to the hydrologic balance and reasons why these impacts are <br />currently not significant and will not be in the future. <br />A) ?m?acl on _ raundwa?er ri hls, Ground water rights within the immediate region {Z mile radius} <br />around the New Horizon Mine are presented in Appendix 2.04.7-1 of the permit.ln all, 29 ground water <br />rights have been identified in the vicinity of the New Horizon 1 and New Horizon 2 mining areas. All <br />monitoring wells installed by the permittee and domestic wells within the surrounding area are shown <br />on Map 2.04.7-1-A. Two wells within the mine area will be affected, the Garvey well Water Right #42? <br />and the Ernest well {Water Right #1 }. These wells, and the land in which they are located, have been <br />purchased by the permittee.
