I <br />have assigned Gordon Bell as my designated inspector. <br />I am a professional engineer registered in the State of Colorado <br />and my experience fulfills the requirements of the Colorado Surface <br />Coal Mining Reclamation Act. <br />The purpose of this inspection and certification was to ensure <br />proper construction of all Sediment Control Ponds and to satisfy <br />the requirements of Rule 4.05.6 (11) (a) of the Colorado Mined Land <br />Reclamation Board. In completing this certification, an inspection <br />was conducted of all Sediment Control Ponds. <br />The inspection showed no problems at the DP-1 Sediment Pond <br />concerning cracking, erosion, rodent activity, or displacements in <br />the following areas; upstream face, downstream face, and the crest. <br />No seepage was located on any of the dam areas. The outlet conduit <br />was in good shape and no leakage was noted. The emergency spillway <br />showed no signs of deterioration or erosion and the riprap was in <br />good condition. No effluent quality could be noted at inspection <br />time, since the pond was not discharging at the outlet. <br />Deserado Mine <br />P.0.
