Several key points in the Department oP Energy (formerly the <br />Energy Research and Development Administration, or E.R.D.A.) <br />lease have an effect on the reclamation plan. They are as <br />follows: <br />1) Because of the possibility that waste dumps may contain <br />what could be in the future a marketable grade oP ore, the <br />major portion oP the dump cannot be removed from the lease <br />block. This stipulation also puts somewhat of a limit on <br />the extent of grading that can be done, that is, the dump <br />cannot be spread over a large area so as to make the material <br />irretrievable in the future. <br />_~) Portals, adits, ventholes, and any other such features of the <br />mine cannot be permanently closed without the approval and <br />consent of the Department of Energy. This would be applicable <br />to the reclamation plan in the event that Cotter would cease <br />mining when the D.O.E. considered the mine to still hold <br />marketable ore. <br />3) According to the lease, reseeding must be done under the <br />recommendation of the surface managers, the Bureau of Land <br />Management. Therefore, Cotter is obligated to use the seed <br />mixture recommended by this agency. <br />4) All pre-existing structures, including roads, must be left <br />intact and restored to their original state at the cessation <br />of mining. <br />B. The angle of repose of the waste material is the steepest angle at <br />which this unconsolidated material will sit naturally without <br />constraints. <br />~_ To Exhibit E, add "In the event 2:1 slopes cannot be achieved, the <br />angle of regraded slopes will not be conspicuously different than <br />the angles of slopes in the surrounding terrain." <br />C. Approximately 2" - 6" of the stockpiled material will be spread over <br />the waste dump and surface facility area. <br />D. Further consultation with the Bureau of Land 1anagement has resulted <br />in a slightly different seed mixture, considered to be more than <br />adequate by this agency. <br />Lbs. pls/A <br />Sand dropseed 0.5 <br />Crested wheatgrass 3 <br />Western wheatgrass 3 <br />Four-wing saltbrush 3 <br />Indian ricegrass 2 <br />Yellow sweetclover 2 <br />
