perennial forbs and shrub seed included as well. All of the species included in the <br /> seed mix are native, with the exception of Orchardgrass and Alfalfa. These two <br /> species have been included to enhance forage utility, improve legume presence in the <br /> stand, and help establish cover. Neither species is considered poisonous or noxious <br /> and is desirable to achieve the post-mining land-use. (Rule 4.15.2) The variety of <br /> alfalfa, Travois, used by Seneca Coal Company has demonstrated compatibility in a <br /> grassland mix at adjacent mines, and has not exhibited excessive aggressiveness. A <br /> variation of Seed mix IA will be used along the haul road corridor and has been <br /> modified as Seed Mix I B to correlate with the Sagebrush Grassland vegetation type <br /> found within the haul road vicinity. <br /> Concentrated narrow areas with higher moisture regimes will be seeded with Seed <br /> Mix No. 2 developed for Mesic Drainage and Subirrigated Sites. This seed mix will <br /> be used to re-establish riparian areas, mesic sites, and may be utilized around <br /> permanent ponds. This seed mix is comprised entirely of native species. <br /> Seed Mix No. 3 has been developed for utilization in localized alkaline conditions. <br /> These conditions may be encountered along the haul road corridor. Alkalaigrass and <br /> Alfalfa are the only introduced species included in this seed mix. This seed mix <br /> complies with Rule 4.15.2. <br /> Seed Mix No. 4 has been formulated to establish quick soil stabilizing cover on <br /> locations that are temporary in nature. Temporary locations would include topsoil <br /> stockpiles and roadside disturbances. <br /> Seed Mix No. 5 has been developed for concentrated shrub establishment areas. <br /> Seneca Coal Company's experience at adjacent mines has shown that higher survival <br /> rates in concentrated shrub seeding areas has been achieved by suppression of <br /> herbaceous competition within the concentrated areas. Accordingly, Seed Mix No. <br /> 5 contains only native shrub species. Seneca Coal Company plans to use mechanical <br /> or chemical means to reduce herbaceous plants within the concentrated shrub areas <br /> until such a time that the shrubs are determined to be able to compete. <br /> Seneca Coal Company proposes to stabilize soil prior to permanent vegetation <br /> establishment through the planting of a cover crop. Either an annual grain or a sterile <br /> grass hybrid (Agroovron x Triticum) will be used. Straw mulch maybe used in lieu <br /> of a cover crop at a rate of 2000 lbs. per acre and crimped or secured with a tackifier. <br /> This meets the requirement of Rule 4.15.4. <br /> Yoast Mine 32 October 19, 1999 <br />
