site in the past, assure that the reluae disposal emban]®ent will <br />be constructed and reclaimed properly and eliminate the concerns <br />~~' which led to the Division's imposition of stipulations on the <br />1983 reiuae lacility revision submitted by the previous operator. <br />Following is a detailed description of the newly revised retuae <br />disposal area design which has been prepared by Energy Fuels <br />Yining Company. <br />1. Size and Confi¢uration: The volume of the revised refuse <br />disposal embanl~eat is approximately 1.3 million cubic yards. <br />Although current projections indicate that the total volume <br />of retuae volume necessary ie only 885,000 cubic yards, this <br />design provides extra capacity for additional reserves which <br />may be found within the mine azea, a lower clean coal yield <br />than projected and/or disposal of sediment collected in <br />drainage control facilities. The area covered by the refuse <br />disposal facility will be 18.58 acres mazimum sad the overall <br />height will be no greater than 145 feet. The aide elopes of <br />the refuse disposal embaaloneat will be 3 horizontal to 1 <br />vertical sad will be uniform slopes rather than terraced ae <br />in previous designs. <br />2. Draiaa¢e: As with both previous designs, all upstream <br />drainage will be diverted away from the retuae lacility. <br />Drainage diversion ditches were properly installed by the <br />previous operator up gradient from the pile as initially <br />designed. Because the revised reluae disposal area design <br />contained herein is nearly identical in size and shape to <br />that originally proposed, no modification to the diversion <br />ditches which are currently in place is necessary to accommo- <br />date thin revision. All drainage generated from the refuse <br />disposal site will be directed to the sedimentation pond <br />located went of the reiuae embanl~ent. Ia previous designs, <br />all drainage generated on the refuse disposal Bite wan <br />collected via terraces and perimeter ditches, which tended to <br />concentrate runoff is small arsaa and create severe erosion, <br />-,, dowacutting and sediment deposition downstream.
