Submittal to the Colorado Division of Water Resources. Dear Ms. Kamnikar: As of Wednesday 13 November 1996, Bill Maclntyre indicated he woul contact you by telephone to assure you that our plan of augmentation will go b fore the State Engineer, possibly as early as next week, and that he will re ommend approval and expects it to be signed. This approved augmentation pl n should be adequate to belay your concerns regarding backfilling, fully tw months ahead of the schedule for which the DMG has been informed of and greed to relative to Pit 1. Relative to soils. As I indicated at the time of the inspection, the ethnical revision did not show all of the soil resources available, but reflected th t portion which I believed would show that adequate reserves were in place. As ndicated at the time of the inspection, the entire fines piles are continuously bei g added to. The June 1996 aerial photograph, and current site conditions, substan late that soil resources have not been fully salvaged or stockpiled. Neithe did the estimates included in the revision include that volume of soil from soil tockpile S, which has grown since your field measurement of it. In response to your inspection report, I have verified the greater accura y of the aerial photograph and remeasured soil resources over the property, tilizing a measured pace and mean estimates of stockpile height and dimensio s [aided by a clinometer], reasonable enough to assure adequate soil reso rtes for reclamation. In doing so, I have adjusted former estimates, making th m more conservative [less volume]. Heights were adjusted down. Cross-sectio s of the tops of piles did not include outslope areas, and were averaged to reflec a mean width. There is in effect, great probability that the actual soil volume on the ground are in excess of that measured and calculated.
