gullies caused by erosion, are on both sides of and within thirty feet of <br />the fence on the west side of the disturbed area. The fill will be <br />mounded 6" to 12" high to provide material to repair any settling that <br />occurs in the future. These areas were identified on the site visit <br />conducted during September, 1995. <br />All Phase I areas including the subsidence repair will be seeded with <br />the approved seed mix and seeding schedule. <br />Phase II includes the removal of the upper diversion ditch, D-3 and <br />D-4, the lower collection ditch, D-1 and D-2, and the sedimentation <br />pond after the reclaimed area is stabilized and vegetative cover has <br />been established. Approval from the Division will be obtained prior to <br />commencing reclamation ofthe facilities. <br />The estimated total volume of material that will be moved is 13,800 <br />bank cubic yards, with 8,500 bank cubic yards being moved in Phase <br />I and 5,300 bank cubic yards in Phase II. The attached Table 1 <br />presents the mass balance for the regrading work and is based on the <br />current topographic map Exhibit 17 and cross sections, Exhibit 18, <br />Sheets 1-3, developed from the current topographic map and the <br />slope stability analysis done in the disturbed area. The Post Mining <br />Topography is shown on Exhibit 19. <br />The following equipment is expected to be used to establish the post <br />mining topography: <br />Bulldozer D-6 or larger <br />Front End Loader <br />Hydraulic Excavator <br />The fill material will be placed in two foot lifts and compacted by <br />mobile equipment, i.e. either a bulldozer or front end loader. <br />(2) (D) Plan for redistribution of topsoil <br />(a) The only topsoil stored at the mine site is the soil recovered from the <br />sediment pond. The plan is to cover the pond site with 1-2 inches and <br />then use the excess soil to cover the site. <br />(2) (E) Plan for Revegetation <br />(a) Schedule for revegetation <br />i. Seeding time schedule, May 15 -June 15 <br />14 A. <br />
