In completing my certification, I have <br />conducted an inspection of the refuse sub-area 1 and 2-3 piles and construction <br />site. <br />'There are no apparent points of seepage in the pile, and there is no indication <br />of slope failure. The surface drainage facilities were adequately maintained <br />and were working properly. No subdrain system is required by our permit, since <br />geotechnical investigation for the disposal site revealed no ground water present. <br />Permanent out slopes have not yet begun to be built. Required compaction was <br />achieved in all lifts through November 14, 1986. <br />We have now, to date, a total of 265,288 tons of refuse placed in sub-area 1, <br />and 187,824 tons placed in sub-area 2-3. <br />Both the topsoil and subsoil piles for those areas have been seeded and are <br />stable. Removal and stock piling of all organic material and topsoil prior <br />to disposal of refuse has been completed. <br />Deserado Mine <br />P.0.
