Colowyo Response: The vegetation monitoring reports for 2006 and 2007 <br />have been updated to reflect this request. Copies of the updated reports are <br />enclosed with this letter. <br />2. In the 2009 vegetation monitoring report, Colowyo has included reclamation block <br />WP001 in the sample data. Reclamation block WP001 is not included in the <br />Partial Phase II Bond Release SL -04 application (it was Phase II Released on 15 <br />August 2001 with SL -03). Colowyo will need to remove all monitoring data from <br />reclamation block WP001 from the 2009 vegetation monitoring report. Please <br />remove all reference to and data from reclamation block WP001 from the <br />2009 vegetation monitoring report. Please redo all cover and sample <br />adequacy calculations as necessary. Please resubmit the 2009 vegetation <br />monitoring report for the Division's review. <br />Colowyo Response: All references to reclamation block WP001 have been <br />removed from the 2009 vegetation monitoring report, as requested. Copies <br />of the updated 2009 report are enclosed with this letter. <br />3. Based on a review of Exhibit 2 — Phase II Bond Release and Map 1 of the 2009 <br />vegetation monitoring report, it appears as though transect 37 may be outside <br />(east of) reclamation block WP004 and, therefore, outside of the requested Phase <br />II Bond Release area. Please review the location of transect 37 from the 2009 <br />revegetation monitoring report and verify whether it is, in fact, inside the <br />Partial Phase II Bond Release SL -04 area. If transect 37 is outside of the SL- <br />04 area, please remove it from the 2009 revegetation monitoring report. <br />Please redo all cover and sample adequacy calculations as necessary. <br />Colowyo Response: It has been confirmed that transect 37 is indeed within <br />the Partial Phase 11 Bond Release SL -04 area. The 2009 report includes this <br />transect in the cover and sample adequacy calculations. <br />4. In each vegetation monitoring report, Colowyo provides a map of the transect <br />locations (starting points) that were sampled for that year. Each of these sample <br />location "dots" has a very large scale. Based on the map scale, each of these dots <br />is approximately 225 feet in diameter (or approximately 0.91 acres). This large <br />size makes it difficult, in some cases, to determine which reclamation block a <br />sample transect is located in (see question 3 above). The Division understands <br />that a larger "dot" is easier to see on the map, but the large size of these dots has <br />added a level of confusion. Please reprint the transect location maps in the <br />vegetation monitoring reports using a smaller "dot" size for the transect <br />locations and resubmit them for the Division's review. <br />Colowyo Response: The scale on the sample location "dots" has been <br />reduced per the Division's request. New maps are enclosed with this letter. <br />
