<br />-- .~. <br />Mr. Richard A. Mills <br />Page two <br />November 1, 1979 <br />Enclosed, find a copy of the review of construction done by <br />our engineer on the dam structure for the sediment pond <br />located near the crusher. This review e.cceeds the requirements <br />of OSM, MSHA and the State of Colorado, as the dam height is <br />less than 10 feet and the capacity of the structure is 5 <br />acre feet plus or minus. <br />Cordially, <br />Daniel R.
