The slope liner is designed with 20 -foot wide crest sloping 1% toward the reservoir. The crest <br />transitions into a 3:1 (H: V) slope extending to bedrock. Stability and seepage analyses indicate <br />this slope configuration and crest width will be stable under existing site conditions. <br />Overburden obtained from the stripping on Di441ie- Veldman property soil appears to meet <br />project specifications for slope liner embankment fill. This overburden will be utilized as a <br />borrow source during slope liner construction. <br />A cutoff key is designed at the base of the liner, offset approximately 5 feet from the prepared <br />mine highwall. The cutoff will extend five feet into the claystone bedrock <br />as directed by-6E4-during construction. The key will be approximately 118 <br />feet wide at the base. <br />Approximately 1 foot of weathered bedrock should be stripped from within the slope liner <br />footprint. Material excavated during foundation preparation including contaminated pit run and <br />bedrock should be placed within the footprints of the ponds @F plaeed .. idiia the Phase ^ 5 <br />baekfill areas. This material should not be utilized as roadway fill. <br />Shaping of the reservoir bottom should not encroach within 25 feet of the toe of the slope liner <br />and reservoir floor excavation slopes, if necessary, should not exceed a slope of 6:1. The <br />reservoirs should be graded to the bedrock low point, as noted in the construction plans. <br />5.2 Top Soiling <br />Topsoil placement will occur as reclamation activities as areas are free from mining activity. <br />Primary areas to receive topsoil as reclamation during the mining process are low -lying areas and <br />other areas in need of fill, such as haul roads and haul roads which lie above the normal high <br />water level (NHWL). Site access roads will be remain in their current state through reclamation. <br />5.3 Wildlife <br />The wildlife plan will not change from the original permit issued, Permit M- 1979 -191. <br />5.4 Revegetation <br />Revegetation will occur concurrently with the mining process as is practical. Care will be taken <br />to regrade and provide reclaimed slopes such that revegetation regrowth may occur to help <br />comply with state and erosion standards. Seeding and grassing activities will take place <br />immediately upon completion of reclaimed slopes (season permitting) whenever practical size <br />areas become available and free from mining activity. Areas not planned for revegetation include <br />Phases 1, 3, and 4 as they will become below -grade ponds. Based on SCS guidance for other <br />local projects having similar surficial soils, the following revegetation procedures are <br />anticipated: <br />
