This pare was updated in conjunction with the USR Application. June 23, 2005 <br />to five years following the completion of mining or filling operations. The mining will <br />leave no highwalls on the property. No acid forming or toxic materials are used or <br />encountered in [he mining. There will be no auger holes, adits, or shafts left on the site. <br />Reclamation Measures -Material Handling <br />Site reclamation measures are illustrated in Exhibit F. Reclamation of the site will include <br />three lined water storage ponds, nine unlined open water ponds, seven silt storage areas that <br />will be reclaimed to wetlands or uplands. <br />Phase 1 Cell 1, Phase 2 Cells 1, 2, and existing small pond, Phase 3 Cell 1, and Phase 5 <br />Cell 3 will be used for silt storage and reclaimed sequentially according to phase number. <br />Individual silt storage cells will be reclaimed as wetlands two to five yeazs after capacity is <br />reached. The proposed topography of the reclaimed cells will be fairly flat and <br />approximately one to two feet below the surrounding area. The area will be reseeded with <br />an appropriate marsh or detention basin wetland seed mix (see proposed seed mixes on <br />pages 21 and 22). <br />Phase 1 Cell 1, Phase 4 Cell 1, and the Plant Site azea will be reclaimed as water storage <br />facilities. The pit highwalls will be sealed with shale material from the floor of the pit and <br />regraded with overburden material The sealed reservoir liner designs are currently under <br />draft by Weiland, [nc. Slopes above and 10 feet below the post-mine water level will not <br />exceed 3H:1 V. Slopes more than 10 feet below the post-mine water level will not exceed <br />2H:1 V, The topsoil will be spread over the surface of the re-graded slopes in all areas <br />above the post-mining lake level; all topsoil-covered surfaces will be revegetated. <br />All remaining ponds will be reclaimed as unsealed groundwater ponds. All pit walls will <br />be re-graded with overburden material. Slopes above and 10 feet below the post-mine <br />water level will not exceed 3H:1 V. Slopes more than 10 feet below the post-mine water <br />level will not exceed 2H:1 V. Topsoil will be spread over the surface of the re-graded <br />slopes in all areas above the post-mining lake level; all topsoil-covered surfaces will be <br />revegetated with the Seed Mix for Upland Areas, page 19. <br />Scrapers will be used to place the backfilled overburden and topsoil. Using scrapers to <br />layer the lifts at a 3:1 slope ensures a stable wnfiguration. <br />Disturbed areas associated with site access and the conveyor will be scarified, covered with <br />topsoil, and revegetated. Topsoil will be replaced, where required, in reclaimed areas at a <br />depth of approximately six to twelve inches. <br />Site gading will be performed to create stable topography and will be consistent with post- <br />closure land uses. Reclamation quantities and costs are summarized in Exhibit L. <br />Water <br />Overburden and mine materials will be inert and impacts to local surface water or <br />groundwater quality aze not anticipated to occur as a result of mining activities.
