Section 816.24(b) Continued. <br />ing and constructing the contour furrows described in Section 780.18, along with the <br />mulching practices described in Section 816.114, will effectively control both wind <br />and water erosion. The reduction in erosion potential from such methods is <br />documented in the work by Clyde, et. al., (19781. <br />Kerr Tipple Area <br />The amount of topsoil available at the tipple site, which was disturbed without <br />salvaging topsoil, is limited. Available on-site topsoil will be supplemented by soil <br />material hauled from the Kerr Mine Area. Placement of available soil will increase <br />infiltration and reduce runoff significantly on the site, as documented by Power et. al. <br />(19741. Also, use of supplemental topsoil has the benefits of improving rooting <br />media for plant establishment, enhancing nutrient cycling, and serving as a source of <br />seed, rhizomes, and root cuttings (Schuman and Power, 19801. Potential compaction <br />will be addressed as it is in the Kerr Mine Area discussion above. Revegetation <br />standards for the area are found in Section 780.18. <br />Marr Mine Area <br />As detailed in Table 71, Marr Mine Area Soils Plan, approximately 0.67 feet of topsoil <br />will be spread over the entire Marr Mine Area requiring topsoiling. Considerations <br />such as compaction and erosion will be handled in a manner similar to that explained <br />in the Kerr North Area discussion above. <br />Section 816.25 Topsoil: Nutrients and soil amendments. <br />Nutrients and soil amendments in the amounts determined by soil tests shall be <br />applied to the redistributed surface soil layer, so that it supports the approved <br />postmining land use and meets the revegetation requirements of Sections 816,111- <br />816.117.
