Long <br />Drv~sion Dveao~ <br />On March 5, 2001, the Division received additional comments from the Division of Wildlife ("DOW") regarding <br />the S & H Mine, File No. M-2000-158. Specifically, please include the following comments [o [he Division's <br />adequacy review letter; <br />The DOW recommends that the applicant be required to establish a detailed monitoring program for review <br />by ~nnside entitizs (e.g. DOW, U.S. Lnvironmental Protection Agency. U.S. Anne Corps' of Enoinezu) to <br />prevent drawdown of groundwater levels in all wetlands, riparian habitat, and cottonwood groves adjacent to <br />the proposed mining activity. The applicants response should correlate with the questions noted by the <br />Division in the February 22, 2001 letter regarding possible impacts to the surface water and groundwater <br />systems, and ways to mitigate such impacts. <br />2. The DOW recommends a buffer of no less than 0.25 miles around the entire roost site (=0.25 miles from all <br />roost boundaries) and would prefer a buffer of 0.50 miles if the integrity and long-term maintenance of this <br />roost is a priority. In addition, the DOW recommends contacting [he U.S. Fish & Wildlife Service regarding <br />the mitigating aspects of disturbing the roost. <br />3. The DOW recommends surveying the area for the presence of Burrowing Owls (in the area defined on the <br />map). <br />If you have any questions, please do not hesitate to call. <br />Si(nce~r~elJy~,~ <br />L/ <br />Erica Crosby ~~ <br />Environmental Protection Specialist <br />Enclosure(s) <br />cc: Carl Mount; DMG <br />Stevan O'Brian: Environment, Inc. w/enclosures <br />
