Dept. of Natural Resources <br /> Mined Land Reclamation Division <br /> 423 Centennial Bldg. <br /> 1313 Sherman St . <br /> Denver, Colorado 80203 <br /> Re: Technical Revision - Tunnel to Wash Plant Conveyor System <br /> File No. C-017-81 <br /> Dear Jim: <br /> Following are the answers to your questions of the <br /> adequacy review comments letter of 4/23/84 : <br /> 1. The detailed reclamation cost estimate has been <br /> submitted. <br /> 2 . Topsoil will be placed just above (north) of the main <br /> transfer point (Geo-Hydro Sheet 3 of 7, revised) . Eighteen <br /> inches of topsoil will be removed from the conveyor route and <br /> bin area, totaling 18, 333 cubic yards. Twenty-four inches of <br /> topsoil will be removed from the tunnel face-up area totaling <br /> 2, 222 cubic yards; all this material will be in one stockpile <br /> (20, 555 cubic yards) . <br /> 3 . We are proposing to store the 64, 000 cubic yards of <br /> underground development waste generated by construction of the <br /> new bins and conveyor tunnel at the rock tunnel existing pile. <br /> We are also proposing to deposit an additional 60, 000 cubic <br /> yards of rock waste from the rock tunnel extension : i . e. , the <br /> No. 2 Mine slopes to the west side of Huntsman Ridge. We have <br /> contacted Geo-Hydro to revise the design for the rock tunnel <br /> storage area. They are presently waiting on us as we are try- <br /> ing to finish the engineering design of the proposed tunnel <br /> size, length, etc. This is not as easy as it might sound, as <br /> it involves the proposed future air flow in No . 1 Mine and No. <br /> 2 Mine, as well as the possibility of No. 3 Mine. For this <br /> reason we would request a 30- to 60-days delay on submitting <br /> the pile re-design. <br /> 4. Maps showing pre-mining and postmining contours are <br /> included 82 x 11; they are copies of portions of Sheets 3 of <br /> 7 and 6 of 7. See originals in Geo-Hydro submittal . <br />
