Box 1949 <br />Fort Collins, Colorado 80522 <br />Re: Annual Reports for: <br />Portland Limestone <br />Boettcher Sandstone <br />Boettcher Gypsum <br />Slab Canyon Limestone <br />Boettcher Limestone <br />Dear Mr. Lochhead: <br />Our File No. 77-344 <br />77-345 <br />77-346 <br />77-347 <br />77-348 <br />Thank you for the above annual reports. They are very good; corrplete and <br />descriptive for all areas. A1I of the reports satisfy the requirements of <br />the law and the following comments are for clarification and informational <br />purposes only. <br />Portland Limestone: We are pleased that concurrent reclamation is being <br />conducted wherever possible. We would be interested in the results of usinrr <br />the soil imprinter. On a mine site in Utah, the use of a "v" shaped soil <br />imprinter actually accelerated crater erosion on the steeper sloFes (loamy <br />soils). <br />Boettcher Gypsum: Bond is now $38,000.00, with maximum affected acreage of <br />90 acres. <br />Slab Canyon Limestone: Bond is now $21,500.00, wit/r maximum affected acreage <br />of 30 acres. <br />Boettcher Limestone: The current $317,000.00 bond is adequate to cover the <br />19 acre increase in affected acreage. As the weathered E-band areas did not <br />have salvageable overburden, what type of growth medium will ~be used on <br />these areas for revegetation purposes? <br />
