The <br /> landowner has no intent to allow public use of the land during mining or site reclamation. <br /> 3.1.5 Reclamation Measures—Materials Handling: <br /> (1) Grading: <br /> Excavation will occur on the top of the plateau. Therefore, little site grading will be <br /> needed. However, any remaining mine slopes will be graded/backfilled to 3H:1V or less. <br /> Also, please see 3.1.5(3) below. <br /> (2) Backfilling: <br /> We do not expect there will be significant backfilling. However, as stated above, all final <br /> slopes will be graded/backfilled to 3H:1 V or less. For example, where the Fo soil unit <br /> mining area meets CyF soil unit mining area, may need grading. The Fo side where the two <br /> units meet will be backfilled and graded to make a smooth transition between the two <br /> different mining depths. <br /> (3) All grading shall be done in a manner to control erosion and siltation of the <br /> affected lands, to protect areas outside the affected land from slides and other <br /> damage: <br /> Since this is the removal of the top of a hill,the final topography will be fairly flat. Soil <br /> unit Ged will be left as a hill between the two soils units which will be mined, Fo and CyF. <br /> Some of the material in soils unit Ged will be graded over Cyf and may be needed for Fo. <br /> The borrow area on soil unit GeD will be graded to 3H:1 or less and will be seed and <br /> mulched. Most soil from runoff events from Ged will be retained by the flat area of CyF <br /> and Fo. Therefore, the potential for off-site slope failure or erosion should be minimal. <br /> We propose to final grade the excavated areas as follows: <br /> • Soils Unit Extraction Area CyF: <br /> ➢ The extraction area within soils unit CyF will daylight to the southwest, where <br /> the plateau drops off the Arapaho Creek. <br /> ➢ The northeast side to the CyF mined area will adjoin two soils units, Fo and <br /> GeD. <br /> 21 <br />
