help to hold water near the root systems of the trees and shrubs. Once the evergreen trees and shrubs have recovered ~.° from the transplanting operation, organic fertilizer will be added to the terraces. These supplements will be applied to add nutrients to the soil, to adjust the acidity of the terraces, and to encourage voluntary revegetation. The relocation of the access road between the Jonathan mine and the Cash mine will result in the construction of O.SSI acres of new road. That portion of the old road that can be abandoned and reclaimed will amount to 0.553 acres. Any top- soil encountered during the construction of the new road will be removed and stockpiled on that portion of the old road that will be abandoned. A thick wood fiber mulch will be applied to the surface of the stockpiled topsoil, and shallow diversion ditches will be dug around the perimeter of the top- soil in order to minimize erosion. It is proposed that the reclamation of this abandoned road will begin within one year of the construction of the new road. This reclamation will start with the ripping and discing of the old road. This will be followed by plowing the surface parallel to the contour of the land. These measures will reduce water runoff velocities, control erosion, and help to prepare the ground for revegeta- tion. Once the appropriate soil amendments and fertilizers have been added to this abraded surface, the abandoned road will be re- .- vegetated. This will consist of broadcast seeding a mixture of grasses in the early spring months and the planting of 30 to 40 pine and spruce trees in six separate pure stands. The grass mixture will contain 6 pounds of Luna Pubescent wheat- grass, 6 pounds of Nordan crested wheatgrass, 6 pounds of Machar smooth brome, and 5 pounds of Vinall Russian wildrye per acre. Ponderosa pine and Blue spruce trees ranging be- tween three and six feet in height will be planted at odd in- tervals along the abandoned road to help encourage voluntary revegetation and reduce erosion. A wood fiber mulch will be applied to the areas where the trees are to be planted. The quality of the surface water that intermittently flows into Cash Gulch will be improved by several methods. At the present time, the water that drains into the gulch from the area above the Cash mine flows over a small mine dump that is situated in the bottom of Cash Gulch, This waste dump was created when the Cash 125 foot level was excavated during the 1870's. When it rains or snows, surface water drains into Cash Gulch and flows over this mine dump and erodes and trans- ports loose waste dump material downstream. By collecting this surface runoff water before it reaches the mine dump and conveying it in a buried culvert, the erosion and downstream sedimentation from this source can be greatly reduced. In ad- . dition, diversion ditches will be excavated above the edges of the mine dump to collect and channel runoff water away from the erodible material. These ditches will also help to con- , trol surface water infiltration and reduce chemical leaching _ of the mineral bearing rock in the mine dump. The construe- ' tion of a settling pond below this area will help to remove suspended sediments from the surface water that intermittently flows down Cash Gulch, These measures will insure that the quality of the water entering Cash Gulch from the affected surface land is permanently improved. -17-
