Colowyo Coal Company L.P. <br />permanent post -mine channels and stock ponds are not being applied for Phase II bond release <br />under this application, and the acreages included in this application have been adjusted to <br />account for removal of the acreages associated with those structures. <br />D. Erosion Control <br />All rills and gullies that may have occurred during the initial years of revegetation were <br />mitigated when they occurred. Erosion control methods implemented for these Phase II areas <br />have been successful and the areas are stable and free of erosion. Successful revegetation efforts <br />have ensured and will continue to guarantee these areas remain free of erosion. <br />E. Sedimentology <br />In accordance with Rule 3.03.3(b), bond liability release cannot be granted until the applicant <br />demonstrates that the existing revegetated area will result in equivalent or lesser sediment <br />contributions to surface runoff when compared with pre -mining levels as determined by baseline <br />data. Please see Appendices B through D which documents the sediment contributions for the <br />areas being applied for Phase II release. <br />SL -14 Phase II and Phase III Bond Release Application Page 7 <br />
