Colowyo Mine <br />TR-72 PAR3 <br />29 January 2009 <br />Page 5 of 8 <br />12. Item Resolved in first adequacy review. <br />13. In previous review letters, both DOW (see attached 7 March 2008 DOW letter) and the <br />Division have requested reclamation plan amendments to address reestablishment of <br />small patches of aspen and tall shrub communities. These community types provide <br />important wildlife habitat functions, even when present as small patches within a <br />landscape dominated by grassland or sagebrush steppe. Previous small scale research <br />and operational plantings have indicated the potential for successful establishment, if <br />appropriate measures are taken. In consideration of the significant acreage of these <br />community types that has been disturbed by Colowyo, and may be disturbed by future <br />operations in the Danforth Hills (Collom), the Division believes it is important for <br />Colowyo to include plans for a limited number of aspen and tall shrub establishment <br />areas in appropriate site locations. <br />Inclusion of aspen and tall shrub plantings in appropriate locations is important from the <br />standpoint of providing habitat for various wildlife species as the stands mature, "islands" <br />for seed and vegetative dispersal in the future and demonstrating successful planting <br />approaches for use in the region. <br />Given the intensity of elk use at Colowyo, and results the Division has observed at <br />Colowyo and other mines in northwest Colorado, including recent and on-going research <br />as well as operational plantings, fencing to exclude elk appears to be necessary for <br />successful establishment of aspen and tall shrub species such as serviceberry and <br />chokecherry. Proper substrate and site conditions, appropriate planting stock, and use of <br />weed barrier or other intensive measures to control herbaceous competition also appear to <br />be necessary considerations. <br />Please review previous letters from the Division and DOW regarding this matter, <br />and provide detailed plans for the establishment of both thick soil <br />(aspen/chokecherry/serviceberry etc.) planting sites and thin/rocky soil <br />(serviceberry, bitterbrush, etc.) planting sites. In the Division's most recent meeting <br />with DOW staff, Jon Wangnild indicated a number of smaller tall shrub and aspen <br />planting sites would be acceptable, in lieu of the two relative large planting areas <br />that DOW had requested in their 7 March 2008 letter. This approach is also <br />acceptable to the Division. <br />14. Please see question 13 above for the Division's response to question 14. <br />15. The appropriate narrative was included in the permit text on Page 2.05-45. Given the <br />importance of this issue, the Division will add a stipulation to the Colowyo permit <br />regarding the Gossard Loadout. The Division considers this Item Resolved. <br />Stipulation 12: The Colowyo Mine submit a complete Technical Revision to the <br />Division to clarify premining and postmining land uses, AVF status, reclamation <br />plan, and AVF restoration of essential hydrologic functions for the Gossard
