Binns of DMG, dated <br />November 16, 1993. <br />Regulations of the Colorado Mined Land Reclamation Board for Coal Mining <br />Review of Permitting Actions Since Last Bond Estimate 11/92 <br />The permit currently does a good job of covering items required by the above mentioned <br />rules. I identified a few concerns, though of minor significance. I will state concerns or <br />discrepancies 1 noted first, then follow with general comments regarding the permit. <br />Soils: 1. Two tables are included describing soil types in the permit. These are Tables <br />3.5-1 and 3.5-2. There is a significant difference in the particle size analysis <br />of the Heldt Silty Clay soil type. One table shows the textural classification <br />as Silty Clay while the other table shows a particle size distribution of Clay <br />Loam. Please explain why this difference exists. <br />iii iiiiiiiiniiiiii <br />999 <br />STATE OF COLORADO <br />
