Soil was placed and spread on the uPP~' <br />most surface of the fill in May of 2004. During the second quarter of 2005, areas disturbed by maintenance <br />of the armored down-drains were seeded using certified weed free straw and the approved rangeland seed <br />mix. The construction access road east of the eastdown-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 cracks, <br />ground movement, springs and seeps, and standing water. No indication of potential instability was <br />observed <br />DOCUMENTATION AND OTHER OBSERVATIONS <br />Late fall conditions prevail with good vegetative cover due frequent precipitation during spring and early <br />summer. Operator was placuig topsoil on a small (+/-0.50 acre) parcel located west of the west down - <br />drain on the second bench. Earlier topsoil/seeding of the area had not been successful. Erosion and shifting <br />of rip-rap on the west down-drain was repaired as hart of this activity. <br />CERTIFICATION <br />This inspection was conducted by Ronald G. Thompson, a qualified professional and MSHA certified <br />inspector of earth and rockfill embanimients and impoundments, under the direction of Mr. Charles <br />McGlothlin, a registered professional engineer licensed in 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 />perswmel, is in accordance with designs as proposed by CTL Thompson in their report dated Apri127 and <br />amended July 27, 2001 and as approved by the Division of Miner~Ls and Geology. <br />a/~' <br />Ronald G.
