<br />Consultants. <br /> <br />Existing Disturbance. Two areas of existing disturbance are found in the proposed <br />mine plan area. These are the existing ranch road and the existing gravel pits <br />which were used for personal, non-commercial use and did not trigger any <br />permitting action. <br />All drainage from the proposed mine area will either initially be discharged into <br />an excavated diversion ditch or diversion ditches which will be directed into <br />sediment ponds which form the perimeter of the mine plan area. These ditches <br />correspond to the outermost edge of the planned disturbance and is depicted on <br />Map 3, Tellier Gravel Pit -Mine Plan Map. All of the surface drainage will be <br />directed through one of three sedimentation ponds before it is discharged into <br />the unnamed drainage containing jurisdictional wetlands, which runs through the <br />property. All of the surface water flowing off the mine disturbance area will be <br />routed into this diversion ditch and through the sedimentation ponds to ensure <br />that the wetland area is no affected by sedimentation. <br />EXHIBIT E <br />Reclamation Plan <br />The proposed reclamation plan for this mine is shown on Map 4, Tellier Gravel Pit - <br />Reclamation Plan Map. Based upon the exploration drill hole data, on average, <br />approximately 8.4 feet of overburden will be replaced on the mine areas, with a <br />range of between 3.5 and 15 feet. The location of the two shallow wetland areas, <br />requested by the Colorado Division of Wildlife are also shown on this map, along <br />with the proposed shoreline configuration. On average, 1.2 feet of topsoil exist <br />on the site this material will be salvaged and utilized for final reclamation. <br />1. Overburden Realacement. Due to the nature of this gravel deposit, it <br />anticipated that approximately 20 percent of the materials to be excavated will be <br />returned to the pit areas as waste or as backfill materials. When overburden is <br />replaced in the excavated pit areas these materials will be reapplied along the <br />edges of the excavated pond area. As mentioned previously, the primary emphasis <br />will be on placing fill along the eastern property boundary. If sufficient fill is <br />available then one or two islands will be constructed in the middle of the pond <br />area.

Reclaimed Sloaes. As recommended by Ms. Elizabeth Miller, the local Wildlife <br />Manager of the Colorado Division of Wildlife, slopes along the perimeter of the <br />pond area will be left in anon-uniform configuration. Maximum slopes will not <br />exceed 3:1 to ensure slope stability. Flatter slopes will be periodically constructed <br />9 <br />
