Cattany <br />Division Director <br />Natural Resource Trustee <br />After our phone discussion earlier this week, l checked into our records regarding bond <br />expenditures at the OC#2 Mine. Records indicate that $19,495.00 was spent on the <br />regrading and revegetation project in 1996. Currently, we have $16,505.00 left in the <br />account. <br />As I had mentioned, we conducted vegetation sampling at the site last summer to <br />evaluate revegetation success. Over-all vegetation cover was 31.1%, compared to the <br />approved standard which is 40.5%, so the site did not "pass" the success demonstration <br />test. On the reclaimed slope areas, cover was only 25.5%, and there was substantial bare <br />ground (49%). There was a patch of the noxious weed Canada thistle on a portion of the <br />reclaimed slope. Vegetative cover was higher, with less bare ground in the pond and <br />stockpile area below the slope. <br />We anticipate using a portion of the remaining bond to conduct further work at the site to <br />improve the vegetative stand on the slope, including herbicide treatment of the thistle <br />infestation, fencing maintenance, and interseeding. The interseeding work will <br />necessitate extension or reinitiation of the 10 year timeclock. <br />Please contact me if you have any questions. <br />Sincerely, <br />~~ __ <br />Daniel athews~ <br />Environmental Protection Specialist <br />C: Denver File <br />Office of Office of Colorado <br />Mined Land Reclamation -Active and Inactive Mines Geological Survey <br />
