As steep <br />cope mining, the reclaimed topography was approved as a variance from approximate <br />original contour. The discussion of the variance is in findings document. <br />The Bear mine had been in existence for over 40 years so the prPm;n;ng topography <br />was unknown. In 1981, prior to rer•lw;m;nq, the mine conducted a stability analysis. <br />The results show that the mine could not be reclaimed to a stable configuration, with <br />a safety factor of 1.3, using the existing material and still meet AOC. Additional <br />material was imported from the neighboring Mt. Gunnison Mine to augment the <br />backfill material, but this was still not enough to meet AOC. <br />The Division granted a variance from AOC for the Bear #2 Mine. <br />This is documented in the Division's findings document. <br />Jim Stover, an environmental consultant representing the mine, has drafted a usable <br />topographic map of the reclaimed topography for the Bear No. 2 Mine. The Division <br />is expecting this map any day and will forward you a copy as soon as we get it. <br />If you have any questions please feel free to call me. <br />Sinter y, , <br />~ /J ---<< <br />Randall/-P/•/.
