Colowyo C-1981-019 <br />19 June 2006 <br />Pg 6/b <br />Excess Spoil (cont.): the time of the inspection. The upper portion of the pile is truck- <br />dumped spoil. This part of the pile appeared to be stable at the time of the <br />inspection. The reclamation plan calls for the top 75 feet of this pile to be hauled to <br />the West Pit to achieve AOC. This is being further addressed in Technical Revision 63. <br />A part of the unreclaimed upper portion of the pile is being used as a storage and <br />work area for mainly the electric cable for the draglines and shovels. The operator <br />indicated that they would begin removing the upper portion of the pile this summer <br />and complete some of the West Pit reclamation (north edge of the West Pit). <br />- Streeter fill was well vegetated and appeared to be stable at the time of the <br />inspection. No erosional problems were noted on the fill. This pile has gone through <br />a Phase II bond release. The operator has submitted Technical Revision 64 to <br />terminate quarterly inspections for this pile. The Division has sent out a preliminary <br />adequacy letter for TR-64. The Streeter pond below, however, still receives runoff <br />from disturbed areas, so it must remain. <br />Overall, the operations and reclamation at the Colowyo Mine are being conducted <br />in accordance with the approved plans contained within the PAP. The operation is <br />doing a good job ensuring compliance with all of the Rules. <br />
