New Elk Mine <br />QUARTERLY COAL WASTE BANK INSPECTION REPORT <br />CDMR Rules 4.09.1(11) and 4.10.2(2) <br />Mine: NEW ELK <br />Waste Bank MSHA ID. No.: Development Waste Disposal Area <br />Inspection Period: First Quarter 2007 <br />Inspection Date: 2/26/2007 <br />General Description or Reference to Site Plan: <br />RECEIVED <br />MAR 2i1 2007 <br />Division of Neclamation, <br />Mining and S2rfety <br />The Development Waste Disposal Area is located south of State Highway 12 and west of <br />the main facility Access Road. It is adjacent to and north of the Middle Fork of the <br />Purgatoire River. The area has been used for disposal of waste rock from the underground <br />mine. Since mine closure in 1989, the area has been used for disposal of sediment removed <br />from ponds and ditches located within the mine permit area. <br />Activtty During Irrspection: <br />Operator finished compacting the active surface of the waste pile in preparation for placement of <br />additional waste resulting from pond cleanout. A fully loaded 30 ton haul truck was used to <br />determine if adequate compaction had been achieved. The truck traversed the active area <br />and minimal deflection of the tires into the waste material was noted. This demonstrated <br />that adequate compaction had been achieved. <br />Drainage: (Discussion of springs. seeps, overland and channel flow, underdrain construction and/or <br />discharge, integrity of 100-year 24-hour drainage sWctures, and evidence of positive drainage). <br />Positive drainage is maintained on the surface of the DWP. No evidence of springs nor seeps <br />was observed. <br />Observation of Fill Construction: (Description of material, compaction, lift thicknesses, slopes, <br />and construction methods). <br />A rolling compaction test demonstrated that adequate compaction was achieved for the last lift <br />of waste material placed on the pile. <br />Page 7 of 2 <br />
