spoil Fiu #8, <br />September 30, 2006 <br />Page 2 <br />FILL PLACEMENT <br />Fill placement has been completed m accordance with the approved plan. No additional fill phrcemert is <br />anticipated. <br />COVER MATERIAL <br />Final fill configuration has been established and topsoil material has been placed on the excess spoil-fill. <br />The area was mulched and seeded in the fourth quarter of 2003. Soil was placed and spread on the upper <br />most surface of the fill in May of 2004. During the second quarter of 2005, areas disturbed by maintenance <br />of the amtored down-drains were seeded using certified weed free straw and the approved rangeland seed <br />mix. The construction access road east of the east down-drain was hand mulched and seeded during August <br />of 2006. <br />STRUCTURAL INTEGRITY <br />The entire excess spoil fill facility was examined for signs of failure and instability such as tension sacks, <br />ground movement, springs and seeps, and standing water No indication of potential instability was <br />observed. <br />DOCUMENTATION AND OTHER OBSERVATIONS <br />No significant erosion was noted and established drainages.appear to be fimctioning as designed. <br />Significant precipitation has occ~ured during the quarter and vegetation shows excellent late season growth. <br />These rain events typically occurred 2-3 days a week with quantities of 0.25-0.60 inches and of reduced <br />irnensity, allowing ilie moisture to permeate the soil with limited run-off. Ram fall on August 27 was l.9", <br />the most intettse event of the quarter. <br />CERTIIrICATION <br />This inspection was conducted by Ronald G. Thompson, a qualified professional and MSHA certified <br />inspector of earth and rockfill embaolmtents and impomdments, under the direction of Mr. Charles <br />McGlothlin, a registered professional engineer licensed m the State of Colorado. <br />This is to certify, to the best of my knowledge and belief, that Fill No. 8 construction and placement, as <br />noted since the previous certification and as determined during this inspection and discussions with mine <br />personnel, is in accordance with designs as proposed by CT'L Thompson in thew report dated Apri127 and <br />amended July 27, 2tR11 a~ as approved by the Division of Minerals and Geology. <br />Ronald G.
