Lochhearl <br />Erecunve Director <br />,Michael B. Lung <br />Dwisinn Director <br />The Division has completed its review of Trapper's responses to the comments contained in the <br />Division's letters dated August 21 and October 6, 1997. <br />The Division considers Trapper's responses to the following comments to be adequate as <br />submitted: <br />8/21 /97 letter <br />Comments 1, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 14, 15, <br />16, 17, 18, 19, 20, 21, 22, 25, 27, 28, 32, and 33. <br />10/6/97 letter <br />Comment 1. <br />The Division anticipates no further comments for RN-03/PR-04 other than those below. <br />Comment 2 (8/21/97 letterl <br />We sincerely apologize for having asked this unnecessary question based on our out-of--date AVS <br />data. We have updated the AVS accordingly. <br />Comment 13 (8/21/97 letterl <br />Please further update Map M-47a and cross-sections C-C' (Figure 4.3-25) and E-E' (Figure 4.3- <br />24a) so that those two lines of section are located inside the pits on the map and the cross- <br />sections depict existing pit geometries. The existing "critical pit crest elevation" (see page 4- <br />98a) now appears to be 6620 ft. for Ashmore pit and 6880 ft. for Enfield pit. Consequently, the <br />annotations for the areas shaded blue on Map M-47a should be changed from 6636 ft. to 6630 ft. <br />for Ashmore pit and changed from 6835 ft. to 6890 ft. for Enteld pit. <br />~~~ II~~I~~~~~I~~~I~ <br />STATE OF COL~,.~ ~~" <br />
