spun Fat n9 <br />March 30, 2007 <br />Page 2 <br />FII.L PLACEMENT <br />CDMG regulations require that spoil be "placed in horizontal fifis in a controlled manner, concurrently <br />compacted as nceessary to ensure mass stability°. Maximum lift thiclmesses are not specified. As indicated <br />by Previous inspection reports, lifts were placed in accordance with plans specified by the CTL Thompson <br />report. Spoil material was transported to the fill area using a combination of trucks and dozers. Lift <br />thiclmesses of up to 50 feet were placed within the area removed from dte fill face by more than 50 feet. <br />Fill placement terminated by seco~ quarter 2002. <br />No fill placement oceurred during this quarter, nor is future placement anticipated. <br />COVER MATERIAL <br />As documented by previous inspection reports, cover placement, seeding and mulching was completed <br />during the sewnd quarter 2002 and upper areas during the second quarter of 2004. During the second <br />quarter of 2005, areas disturbed by maintenance of the armored down rains were hand seeded using <br />certified weed free straw and the approved rangeland seed mix. <br />STRUCURAL INTEGRITY <br />The errtire excess spoil fill facility was examinal 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 />Early spring conditions prevail with some new vegetative growtlt noted, lr7cely due to the southern aspect of <br />this fill area. <br />This inspection was conducted by Ronald G. Thompson, a qualified professional and MSIIA certified <br />inspector of earth and rock-fill embaol®ents and impoundments, under the direction of Mr. Charles <br />McGlo0rlin, a registered professional engineer licensed in the State of Colorado. <br />This is to certify, to the best of my knowledge and ballet; that Fill No. 9 construction and placement, as <br />noted since the previous certification and as determined diving this inspection and disrmssions with mine <br />perso~l, is m acoordance with designs as proposed by CTL Thompson in their report dated April 27 and <br />amended July 27, 2001 and as approved by the Division of Minerals and Geology. <br />Ronald G.
