• 4.06 TOPSOIL <br />4.06.1 General Requirements <br />Before the disturbance of any area, topsoil is removed and segregated from other material. <br />Upon removal, this material is either immediately redistributed on regraded areas or <br />stockpiled in locations shown on the Topsoil Handling Maps 28 and 28A. <br />4.06.2 Removal <br />All topsoil, as classified in section 2.04.9, is removed from areas to be affected by the surface <br />coal mining operations. The graphical representation of the topsoil removal is shown on the <br />Topsoil Handling Map (Map 28 and 28A). This map has been greatly simplified from that of <br />the original application to reflect actual on-the-ground operations. The techniques for <br />removal of woody plant materials that otherwise would interfere with the usefulness of the <br />topsoil is discussed in Section 2.05.3 <br />The average thicknesses for each soils series: to be removed can be found in the legend of the <br />Soils -South Map (Map 6). Removal techniques for topsoil is described in Section 2.05.3. <br />A variance from topsoil removal was requested and approved by the Colorado Division of <br />Minerals and Geology for the following areas; construction of small structures such as power <br />poles, signs or fence lines, areas of light traffic that do not destroy existing vegetation or <br />cause erosion and areas where removal would result in needless damage to soil <br />characteristics such as sediment control ditches and small water diversions. In most cases, <br />especially on steep slopes, removal of topsoil prior to ditch construction needlessly damages <br />large areas of topsoil, along with the adjacent natural vegetation. Implementation of the <br />technique of cutting the ditches directly into the hillside without topsoil removal will limit <br />needless topsoil disturbance, reduce unnecessary destmction of adjacent vegetation and will <br />facilitate reclamation of the ditches at a future date. <br />4.06-1 Revision Date: 11/02/05 <br />Revision No.: TR-62 <br />
