• 4.15.4 Mulching and Other Soil Stabilizing Practices <br />The regraded areas will be treated with mulch as set forth in Section <br />2.05.4 to reduce erosion, promote germination of seeds, and increase the <br />moisture retention capability of the graded soil material. The mulch <br />will be mechanically anchored to the surface to ensure effective <br />protection of the ground and vegetation. In addition to the mulching <br />plan, other erosion control methods will also be utilized on the <br />reclaimed area. The material will be graded to minimize long and <br />uninterrupted slopes. Grading will be followed by chisel plowing and <br />contour furrowing on steeper slopes. The use of contour furrowing on <br />steeper areas will reduce the formation of any rills or gullies from <br />surface runoff. <br />4.15.5 Grazing <br />Because of the compact nature of the reclaimed area, even though the <br />• proposed post-mining land use is rangeland, no grazing will be conducted <br />on the reclaimed area. Any grazing studies would be meaningless given <br />the small area to be reclaimed. <br />4.15.6 Field Trials <br />No field trials for vegetation are anticipated for the mining operation. <br />4.15.7 Determining Revegetation Success: General Requirements and <br />Standards <br />The area of surface facility relocation is extremely compact, <br />approximately 7 acres in size. Likewise, this area has been previously <br />disturbed by the facilities of past underground mining activity. <br />Therefore, Sunbelt proposes to measure the success of revegetation based <br />on local environmental conditions and other available data for similar <br />sites. <br /> <br />4.15-2 <br />
