Mine: NEW ELK <br />Waste Bank MSHA ID. No.: <br />Inspection Period: <br />Inspection Date: <br />General Description or Reference to Site Plan: <br />Activity During Inspection: <br />New Elk Mine <br />QUARTERLY COAL WASTE BANK INSPECTION REPORT <br />CDMR Rules 4.09.1(11) and 4.10.2(2) <br />Primary Refuse Disposal Area (RDA) <br />Third Quarter 2011 <br />8/29/2011 <br />The Refuse Disposal Area is located north of State Highway 12 and the Middle Fork of the <br />Purgatoire River with refuse transported from the preparation plant to the RDA by conveyor belt. <br />The plant has operated intermittantly during 2011 with resumption of mining and trouble shooting <br />plant modifications. The operator has concentrated on improving grade on the working bench. <br />Compaction test conducted by CTL- Thompson detrmine that the pile is being constructed as <br />per approved plans. <br />Operator was relocating previously place refuse from the back northwest quarter to the from one - <br />third of the working surface. This will reduce the grade and reduce erosion during precipitation <br />events. The year 2011 has been dry and erosion has not been a problem. <br />Drainage: (Discussion of springs. seeps, overland and channel flow, underdrain construction and/ <br />or discharge, integrity of 100 -year 24 -hour drainage structures, and evidence of positive drainage). <br />No springs or seeps were observed on the refuse side slopes. Positive drainage is established on <br />all areas. Vegetation is well established on previously reclaimed areas. <br />Observation of Fill Construction: (Description of material, compaction, lift thicknesses, slopes, <br />and construction methods). <br />No new fill was placed during the quarter. <br />Indications of Potential Failure or Instability: <br />None observed. Surface and side slopes were inspected for slumps, tension cracks, and other <br />indications of potential failure. <br />Threat to Human Life or Property: <br />None observed. Location and placement minimize potential impacts to life or property. <br />Page 1 of 2 <br />
