of the species included in the seed mix are native, vvitkr the ~axception of <br />Orchardgrass and Alfalfa. These two species have been included to enhance <br />forage utility, improve legume presence in the stand, and help establish cover. <br />Neither species is considered poisonous or noxious and is desirable to achieve <br />the post-mining land-use. (Rule 4.15.2) The variety of alfalfa, Travois, used <br />by Seneca Coal Company has demonstrated compatibility in a grassland mix <br />at adjacent mines, and has not exhibited excessive aggre:;siveness. A variation <br />of Seed mix lA will be used along the haul road ce>rri~dor acid has been <br />modified as Seed Mix 1B to correlate with the ;iagebrusti Grassland <br />vegetation type found within the haul road vicinity. • <br />Concentrated narrow areas with higher moisture regimes will be seeded with <br />Seed Mix No. 2 developed for Mesic Drainage and Subirrigated Sites. This <br />seed mix will be used to re-establish riparian areas, me:sic sites, and may be <br />utilized around permanent ponds. This seed mix is c:omprisecl entirely of <br />native species. <br />Seed Mix No. 3 has been developed for utilization in locali::ed alkaline <br />conditions. These conditions may be encountered ,long the: haul road <br />corridor. Alkalaigrass and Alfalfa aze the only introduced species included <br />in this seed mix. This seed mix complies with Rule 4.15.2. <br />I <br />Seed Mix No. 4 has been formulated to establish quick soil stabilizing cover <br />on locations that aze temporary in nature. Temporary locations would include <br />topsoil stockpiles and roadside disturbances. <br />Seed Mix No. 5 has been developed for concentrated shrub establishment <br />areas. Seneca Coal company's experience at adjacent trines' has. shown that <br />higher survival rates in concentrated shrub seeding areas has been achieved <br />by suppression of herbaceous competition within the concenU-ated areas. <br />Accordingly, Seed Mix No. 5 contains only native shrub species.:ieneca Coal <br />Compa.~ plans to use mechanical or chemical means to reduce herbaceous <br />plants within the concentrated shrub areas until such a timelthat the shrubs <br />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 <br />or a sterile grass hybrid (Agropyron x Triticum) will be: used. Straw mulch <br />may be used in lieu of a cover aop at a rate of 20(10 lbs. pcr acre and <br />crimped or secured with a tackifier. This meets the requirement of Rule <br />4.15.4. <br />Yaact r~.uue 34 July 6, 1995 <br />
