• Revegetation methods, including seedbed preparation and seeding, are similar to that presented earlier in the <br />revegetation plan discussion for the New Horizon Mine. Exceptions include the possible use of the grass drill <br />specified in the irrigated pasture revegetation discussion in lieu of the rangeland type drill and the use of cover <br />crop for surtace stabilization only on steeper slopes. No mulching is planned for these small areas, however, <br />a cover crop will be seeded as a surtace stabilization measure. Management and maintenance activities will <br />include any necessary repair of rills or gullies (detailed at the end of this section), reseeding, or grazing <br />management. Grazing management will be centered on the proper use by livestock of the dryland pasture <br />areas in relation to the associated irrigated pasture. These areas will initially be irrigated by water cannon for <br />the first 3 years to insure successful establishment of the dryland pasture. They will not be irrigated after the <br />initial three year period. Dryland pasture will only receive an initial fertilizer application at the time of seeding. <br />Additional Revegetation Measures <br />Shrubs and bushes are not planned to be planted because of the post mining land use. The owners of the <br />reclaimed land (both 1987 and 1999) do not want shrubs or bushes in their fields. Shrubs would intertere with <br />theirfarm activities. WFC does anticipate volunteerwillows to grow in low lying swales and drainage channels <br />adjacent to sediment ponds. <br />Table 2.05.4(2)(e)-1 and Table 2.05.4(e)-2 represents the estimated acreage of the various reclaimed <br />vegetation types to be established within the New Horizon 2 Mine area for 1987 and 1999 respectively. Also <br />included are 9.23 acres of replaced county road. Table 2.05.4(2)(e)-3 are the various vegetation types within <br />the existing (1987) and amended (1999) disturbance areas for both pre-mine baseline vegetation and post- <br />mine revegetation. Map 2.05.4(e)-1 indicated where the various post-mine vegetation types will occur. Map <br />2.05.4-4 shows the replacement depths of topsoil. <br />Revegetation Standards and Procedures for Testing for Successful Reclamation <br />Irrigated Hayland Type One area of irrigated hayland will be established on reclaimed land in the original <br />permit and one on the amended area (Morgan property) within the New Horizon permit area. These areas <br />occur in the southwestern portion of the permit areas (SE1/4 NW1/4, Section 6 T. 46N., R.15W.) and (NE1/4, <br />NE1/4, Sec. 1, T.46N., R.16W.) respectively. The first arewill be reclaimed to a grass dominated hayland and <br />the Morgan area will be reclaimed to a alfalfa dominated hayland (seed mix #7) as detailed earlier. Because <br />of marginal site conditions and shallow soils, grass hayland was chosen as the land use for the first site. <br />Alfalfa dominated hayland was chosen for the second site as Morgan currently has the pasture in alfalfa <br />• hayland. <br />(Revised ii/z~/oo) 2.05.4(2)(e)-11 <br />
