As vegetation becomes established, stabilizing the area, selected diversion ditches will be <br />graded -in and seeded with the appropriate range site mix. This normally will not occur until the <br />second or third year of vegetation establishment. Also, it is unlikely that all the diversion ditches <br />in an area will be graded -in at the same time. Most likely, removal will be spread out over <br />several years. Those diversions that feed livestock ponds and/or enhance the postmine stream <br />density and long term postmine watershed stability will be retained as part of the postmine <br />drainage system. Division approval will be obtained prior to leaving diversions as part of the <br />postmine watershed. <br />Even with the installation of diversion ditches and performing reclamation practices on the <br />contour, some sideslope gullies may form. In order to control such features, Trapper will <br />annually, following spring snow melt runoff, inspect all of the regraded and retopsoiled areas <br />for sidesfope guffies. Where such gufffes exceed fen feet in length and twelve inches in depth, <br />they will be stabilized by November 15 annually. Stabilization will include seeding and the <br />application of such material as hay bales or other equally effective material(s) such as rolled <br />matting staked into the gully. The overall goal is to stabilize the gully and effectively control <br />gully sediment generation. <br />Sideslope gullies are not anticipated to be tributaries to drainageways. Further, they are <br />expected to begin healing as perennial vegetation becomes established. In the event some <br />sideslope gullies remain active over several runoff seasons, they will be included under Section <br />4.8.1.3 of our permit which addresses stabilization of drainageways, subject to the Division's <br />concurrence, and so treated. <br />3-151 <br />Revision: <br />Approved:3 U3 <br />
