<br />TRAPPER MINING INC. <br />I, Collin R. Fay, a Registered professional Engineer in the State of <br />Colorado, in accordance with 2CCR407-2, Section 4.05.6(7), certify that <br />Middle Pyeatt Dam ~IkL, Middle Pyeatt Dam ;k2, and Middle Pyeatt Dam ~k3, Located <br />in Section 26, T6N, R91W, 6th PM, were inspected by me during construction. <br />Construction of these dams was begun on September 15, 1986, and completed on <br />October 13, 1986. Final surveying was completed on October 14, 1986. I <br />certify that the embankments were built as designed and the resulting sedi- <br />ment control system will meet effluent limitations as predicted by hydrologic <br />modelling techniques. <br />During construction, the dams were visually inspected daily to insure compli- <br />ance with prudent construction methods. Compaction was accomplished by <br />laying fill in thin horizontal layers and compacting with a vibratory roller <br />compactor and dozers and/or scrapers. Standard Proctor densities were deter- <br />mined in our lab using methods outlined in AASHO Sta/nlda/r/d Method T9 61. <br />~~ppS RE~~J~ G~ <br />• ~'~1CNAIFp' <br />~~~.• ~• ~ <br />.`p~`~ ~:~ Collin R.
