The surface can also be roughened by ripping the base, which may facilitate mixing the coarser, rocky material of <br />the spoil material with the gully bottom. <br />• The area upslope of excessive rills and gullies can also be manipulated to decrease the amount of water flowing into <br />existing rills and gullies. Such techniques include contour furrowing, staggered furrows, spreader dikes, diversion <br />ditches, ripping and mulching. These dispersion techniques may also be used downslope of or over the regraded <br />rills and gullies. Again, one or a combination of the previously mentioned techniques may be implemented for the <br />repair of excessive rills and gullies. <br />Diversion ditches may be installed in some instances to channel overland flow away from newly reclaimed areas. <br />Diversion ditches will be constructed as outlined in pages 28-13 through 28-15 of this Exhibit. <br />The Division may review ongoing survey, monitoring, and repair work during the field season at their convenience. <br />The following discussion of permanent drainageways consists of two parts. The first involves a demonstration that <br />gully formation at Mines 1, 2, and Eckman Park is a natural occurring process and the density of permanent <br />drainageways within the reclamation is no greater than surrounding, similar undisturbed areas. The second portion <br />addresses the stabilization and maintenance plan for permanent drainageways. <br />• <br /> <br />APPROVED OCT J ?. 1998 <br />MR 98-88 28-6 ~, i~ 9/4/98 <br />
