subsoil was salvaged during 1981. This soil was salvaged from the active waste area. <br /> WFC proposes to utilize all of this salvage material to reclaim active and future waste <br /> material. <br /> The remaining areas shown on Figure 1 will be reclaimed with in-place material. <br /> Soil samples were taken to a depth of 18 inches to evaluate the suitability of this material <br /> for revegetation. Providing the results are favorable, WFC will loosen in-place material <br /> by ripping and preparing the seedbed using standard reclamation practices. <br /> Revegetation Success <br /> The proposed post-mining land uses for the Golden Eagle Mine are irrigated hayland <br /> and grassland. The areal distribution of these land uses is shown on Figure 2. <br /> Target levels for evaluating revegetation of irrigated layland are presently being <br /> developed. WFC supplies the Division with annual irrigated hayland production figures <br /> from lands adjacent to the mine water in-take pond and sediment Pond 003. At the end of <br /> the five (5) year term, WFC will average these production figures. The mean production <br /> shall constitute the target level for evaluating revegetation success. Revegetation <br /> production shall be considered equal if it is at least 90 percent of the mean target level <br /> with 90 percent statistical confidence. <br /> Grassland areas falling under the requirements of Section 4.15.10 shall be considered <br /> reclaimed when the ground cover is equal or greater than 22 percent. Twenty-two (22) <br /> percent is taken from Page 22 of Exhibit 12 of the Golden Eagle Permit Application. <br /> Twenty-two (22) percent was the mean cover value obtained from the Golden Eagle <br /> reference area during 1981 vegetation studies. <br /> Grassland areas falling under the requirements of Section 4.15.8 shall meet the <br /> following criteria: <br /> 1. Herbaceous cover shall be at least 90 percent of the cover as determined from the <br /> Golden Eagle grassland reference area with 90 percent statistical confidence. <br /> -11- <br />
