TR-07 RECLAMATION PLAN <br /> REQUIREMENT 6: In the process of grading the land, closed basins will not be created unless <br /> such a basin is required to control runoff and sediment discharge. If such a basin is needed it will comply <br /> with the requirements stated in the "Water Control Requirements"portion of this Reclamation Plan. <br /> REQUIREMENT 7: Drainage Re-connection Requirements. (This requirement is also <br /> included in the"Water Control Requirement"portion of this Reclamation Plan). <br /> 1. Small drainages naturally occur on the side slopes of hills and form a significant <br /> part of the general character of the topography. <br /> 2. Re-establishing these drainages in an area that has been mined is important. <br /> 3. Drainages will be constructed using a flow line that closely simulates other unmined <br /> drainages in the area. <br /> 4. Straight line drainages will not be created. A gentle winding pattern is more <br /> effective and natural. <br /> 5. If the drainage requires small basins due to its length or grade, the basins will be <br /> created in accordance with the requirements for closed basins stated in the"Water <br /> Controls"portion of this Reclamation Plan. <br /> REQUIREMENT 8: Grading shall create gentle slopes with a gradient not to exceed 5:1. <br /> REQUIREMENT 9: The edges of backfilled and graded pits shall not exhibit abrupt breaks in <br /> the slope. The grading will create a gentle transition from unmined land to mined and backfilled land. <br /> (NOTE: This is similar to a requirement stated in the Backfill portion of the Reclamation Plan. It is <br /> repeated here because of its importance. Please refer to that previous section for a discussion of this <br /> requirement.) <br /> REQUIREMENT 10: Final grading of the surface will not be smooth. The final grading will <br /> create a mildly ridged final surface. The ridges will more or less parallel the contours of the slope. The <br /> depth of the "valleys"between the ridges should be on the order of two to four inches. The final surface <br /> should look quite a bit like corduroy fabric. <br /> (TR-07 Note: Due to the nature of the area yet to be mined, this requirement does not have much <br /> actual importance. This is because the land has a very gentle slope. As the mining limit adjacent to the <br /> drainage to the east is near the top of the slope leading into the drainage, slippage is not likely to occur.) <br /> Coal Creek Sand Resource Amendment 3 (2005)- M-1988-044 Exhibit E Page 11 <br />
