iiiiiiiiiiiiiiiiiii <br />O o v <br />v <br />~~:'tt~~Ri~~~U~ <br />Doc Da etet 1211112001 <br />For J. A. Kiger January 9, 1995 <br />WEST PIT EXCESS SPOIL FILL CONSTRIICTION IIPDATE AND CERTIFICATION <br />On December 29, 1994, I inspected the area in which the West <br />Pit Excess Spoil Fill is being constructed. The purpose of this <br />inspection was to observe the on-going construction of the surface <br />rock drain that borders the 3:1 Excess Fill Slope, inspect the fill <br />for areas of water seepage or surface drainage, inspect the final <br />grade slopes below the 7050 elevation of the Excess Fill Slope, and <br />to satisfy the requirements of CDMG Rule 4.09.1(lla). <br />During the inspection it was observed that the surface rock <br />drain bordering the Excess Spoil Fill 3:1 slope had been completed <br />from the 6859 elevation (toe elevation) to the 7025 elevation, the <br />Excess Spoil Fill had been final sloped from the 6859 elevation <br />(toe elevation) to the 7050 elevation, and that construction of the <br />two percent ditch that runs across the face of the fill at the 6950 <br />elevation was complete. <br />I am a mining engineer, registered in the State of Colorado, <br />and experienced in the construction of rock and earthen projects <br />for the purposes of mining activities. <br />To the best of my knowledge, based on my professional <br />expertise the West Pit Excess Spoil Fill has thus far been <br />constructed in conformance with the prudent state-of-the-art <br />methodology for earth and rock fill construction, as specified in <br />pages Ia-2 through Ia-4, Exhibit 19Ib, and other applicable <br />requirements of the approved permit documents, a portion of CDMG <br />Permit C-81-019. <br />~rn`O% Stephen R.
