In accordance with landowner desires, theredamation plan. will be directed toward replacement mad enhancement of the dominant irrigated Kayla od and pastureland land uses. Small areas of steeper slopes or property corners difficult to irrigate will be planted to dtyland pasture, in accordance with landowner requests. Reclamation efforts will not be directed toward restoring the minor acreage of depleted sagebrush rangeland, or the attiftially subirrigated swale areas. It is anticipated that wetland vegetation will establish in low spats =d adjacent to impoundments on the reclaimed landscape, due to the pmence of water frnmi. inioon runoff. Continued incidental use of the reclaimed landscape by wildlife similar to drat, which occurred prior to mining, is expected.

Y?? Water Rights and sage C)o k,5 I The water rights, usage and augmentation plan is presented in 5ectioU 2.056(3) of the permit application. There are 11 surface water rights that have the potential of being impacted by Western t Fuels operations at New Horizon Mine 2. These are upgradient of Sediment Pond 007 at the site. 2 of 0?41 on figure '11ere are 29 water wells adjacent to the mine sites. of these, just two, W-1109 and D- mining activities at the New Horizon Mine 2 site. Thcse Tab 16,could be impacted by future two wells are 150 feet or less deep and derive their water from r=ear surface aquifers. At the end of five years of operation, Western. Fuels estimated that dtawdown might be one foot within a 0,7 mile radius of the ce=nter of the New Horizon, Mine 2 pit. Western Fuels proposes, with owner consent, to monitor these wells to detect any changes in their hydrologic conditions. Western Fuels-Colorado will use the following alternative water sources to mitigate any ground or surface water right impacts. Western Fuels has available 114,5 acre-fit of surface water, which is a consumptive use credit associated with Western Fels` ownership of 27 shares of the Colorado Cooperative Company (CCC). Western Fuels has an absolute 4 acre-foot storage right fors the 001 reservoir at the New Horizon Mine I area and is projected to have 19 acre-feet of pit uanptxg the non-irrigation season available to them for use. Western Fuels also has a 1.5 acre-foot ground water right associated with the mitred.-out strop well, It is from these alternative sources of water that the surface water augmentation Plan has been developed. No ground water impacts requiring nnitigation are forecast. However, should a ground water supply be diminished to such an extent that it precludes its use, Western fuels will replace this supply with surface water available to them (only 62.1 of the 114.5 acre-feet of CCC water is required for the surface water augmentation plan) or. WFC will re-drill s new well. 13
