• Significant revegetation has already been conducted at Hine No. <br />3 and certain tracts seeded prior to the Federal interim program <br />have been released from bond under the terms of CYCC's ezisting <br />permit for Mine No. 3. <br />Bevegetation is one of the most important methods available for <br />controlling erosion and minimizing sediment yield, Seeding and <br />planting disturbed areas will be conducted primarily during the fall <br />when conditions are the moat favorable. Soil stabilization <br />practices will be emphasized as a major part of sediment control, <br />The primary soil stabilization factor is revegetation of reclaimed <br />laada; as the vegetative cover and root zone are reestablished <br />runoff and erosion rates are reduced, <br />• <br />Contour furrowing has been used in the past with much success <br />and will be used on all areas to be revegetated within the proposed <br />permit area. A cross section of the contour furrow to be used in <br />the proposed permit area is show in Figure 13~ Design of Typical <br />Contour Furrow. The furrows provide closely spaced small <br />depressions within the topsoil layer that not only greatly reduce <br />sheet flow velocity and subsequent eroaion~ but will also trap any <br />transported sediment near its original location. By the time that <br />revegetated stands have developed to a point that sediment transport <br />is no longer a significant problem and the contour furrows are no <br /> longer needed, the furrows will have filled with topaoil~ will blend <br />• in with the land surface and will become inconspicuous.
