<br />Stage 2: Stage 2 adjoins and lies on the west side of <br />Stage 1. After mining operations are <br />completed in Stage 1, topsoil is windrowed <br />aside on the Stage 2 area; overburden from <br />Stage 2 is removed and replaced on Stage 1; <br />the windrowed topsoil on Stage 2 is removed <br />and replaced on Stage 1. <br />Seeding (Stage 1): The topsoil replacement on Stage 1 <br />(and all stages) shall be scheduled so that <br />seeding can be done immediately and during the <br />proper season to deter wind/water erosion. If <br />topsoil is windrowed for any extended time, <br />the windrows side slopes will be reduced to <br />3H:1V maximum slope and temporary appropriate <br />seed mix will be sewn on the windrows to <br />reduce wind erosion. <br />Stage 3: Steps in Stage 2 will be repeated for Stage 3, <br />replacing soils on Stage 2 removed from Stage <br />3. <br />Stage 4: Stage 4 is the final reclamation phase wherein <br />mining is completed and soils (overburden and <br />topsoil) are removed from the respective <br />stockpiles, replaced and spread on the Stage 3 <br />area which is the final remaining disturbed <br />area. Seeding will be executed per the <br />approved reclamation plan. <br />Drainage Control: <br />Drainage will be controlled by daylighting pit <br />bottom drainage to the existing borrow ditch of <br />Colorado Highway 14. <br />Pit Depth: <br />The designed pit depth is determined to be <br />approximately 15 to 20 vertical feet. The final <br />pit bottom elevation is to be controlled by the <br />above described drainage that daylights/drains to <br />the east of the proposed mining area. In this <br />manner, sufficient drainage is available via <br />gravity flow from the proposed mine. <br />Pit/Pile Slope Angle: <br />Pit walls or stockpiles shall not exceed a <br />slope angle of 3H:ly. <br />3 <br />
