• As vegetation becomes established, stabilizing the area, selected diversion ditches will be graded-in <br />and seeded with the appropriate range site ma. This normally will not occur until the second or third <br />year of vegetation establishment. Also, it is unlikely that all the diversion ditches in an area will be <br />graded-in at the same time. Most likey, removal will be spread out over several years. Those <br />diversions that feed livestock ponds and/or enhance the postmine stream density and long term <br />postmine watershed stability will be retained as part of the postmine drainage system. Division <br />approval will be obtained prior to leaving diversions as part of the postmine watershed. <br />Even with the installation of diversion ditches and performing reclamation practices on the contour, <br />some sideslope gullies may form. In order to control such features, Trapper will annualy, following <br />spring snow meR runoff, inspect all of the regraded and retopsoiled areas for sideslope gullies. Where <br />such gullies exceed ten feet in length and twelve inches in depth, they will be stabilized by November <br />15 annually. Stabilization will include seeding and the application of such material as hay bales or other <br />equally effective material(s) such as rolled matting staked into the gully. The overall goal is to stabilize <br />the gully and effectively control gully sediment generation. <br />sideslope gullies are not anticipated to be tributaries to drainageways. Further, they are expected to <br />• begin healing as perennial vegetation becomes established. In the event some sideslope gullies <br />remain active over several runoff seasons, they will be included under Section 4.8.1.3 of our permit <br />which addresses stabilization of drainageways, subject to the Division's concurrence, and so treated. <br />-. _~ <br />3-1st , ZEVISION APPRO ED iI <br />I I DATE --- -' <br />I` - J <br />
