Debris, organic matter, coal, etc., present in fill None visible <br />2. General gradation and characteristics of material Gradation of core & upper fill <br />as snecified. Fine granular material has been cast into previous pit. Large_ <br />blocky material has been placed in underdrain as specified, underdrain materials <br />3. Presence of water, surface and ground ~,~nnnd water Pmaroina from the nndPr-_ <br />drain at a rate of 10 to 15 gpm. Underdrain appears to be functioning properly. <br />Surface water & pit drainage is being diverted around the underdrain. <br />4. Condition of underdrain (approx. current width, depth, and length), material <br />gradation and characteristic, compaction, presence of water Current placement <br />a roximately 20'-25' wide by 15'-20' deep. Current length of underdrain is <br />2100'. Due to snow melt conditions & general snow cover, the area is wet, but <br />no unusual ponding was noted. <br />5. General material movement No unexpected movement evident. <br />6. Proximity and treatment of seep points None observed <br />7. Condition of slope fill surface (grading, cracks or sloughing, erosion, <br />revegetation Fill surface has not been rough graded as of this inspection <br />8. Recommendation Continued observation & inspection as construction progresses <br />downslope. <br />9. Accountability <br />I certify the preceding observations and comments to be true and accurate to <br />the best of my knowledge. <br />~~S NIC/y <br />. ~ <br />vJ~'~~ECrf~~, l <br />. 1 s~ %/T <br />•w <br />.~ ~, <br />:n <br />i4 r:, W <br />,f~~ fr1 fFl~~ <br />~~ ~ ~Q~ <br />Colorado P.Ee 17274 <br />Ua~e <br />
