Pineda <br />Colorado Springs, CO 80949 Director <br />Re: Katuska Pit, Permit No. M-1991-037, Technical Revision TR-3 Adequacy Issues ? <br />Dear Mr. Astemborski: <br />On 14 March 2011 the Division of Reclamation, Mining and Safety (Division) received your <br />Technical Revision TR-3 request to update and revise the mining and reclamation plans. The <br />Division needs you to respond to the following adequacy issues before TR-3 can be approved: <br />1) The TR refers to a map, but no maps were enclosed. Please enclose both a Mining Plan map and <br />a Reclamation Plan map containing the information requested in the following bullets. <br />2) Include on the Mining Plan map the extent of your proposed Phase 1 mining operation. Also on <br />the Mining Plan map show the dimensions of any significant disturbances to the land surface such <br />as pit excavations, mine benches, impoundments, stockpiles, waste rock disposal areas, etc. <br />3) The TR states that when reclamation is finished it will be at 3:1 slope or flatter. Please describe <br />in the text and indicate on the Reclamation Plan Map which areas will be reclaimed to 3:1 slopes. <br />Include on the Reclamation Plan map the final slope configuration of the entire permit area. <br />4) The TR states that the pit will be backfilled with a mixture of sand and gravel. Please indicate <br />whether the source of the backfill material will be from inside the permit area or from off site. <br />5) Please provide the estimated water requirements of the project and the source of the water. <br />Be advised that you may not deviate from the existing Mining Plan until Technical Revision TR-3 <br />has been approved. You may call me with questions at (303) 866-3567 x8108. <br />Sincerely, <br />a&? <br />David Bird <br />Division of Reclamation, Mining, and Safety <br />Office of Office of <br />Mined Land Reclamation Denver • Grand Junction • Durango Active and Inactive Mines
