operations, or in compacted non - topsoiled temporary reclamation. In addition, areas with excessive <br />• weeds or undesirable vegetation growth may be controlled by mechanical tillage using offset disking <br />on the contour. In shrub establishment areas, competing herbaceous vegetation may be controlled or <br />eliminated by contour disking operations prior to shrub seeding or planting. The shrub establishment <br />areas will be identified in the field and tillage will be conducted a sufficient number of times during <br />the growing season to control vegetation. <br />Controlling weeds or other competing vegetation in seeding or shrub planting areas may also be <br />carried out through the use of chemical herbicides. Large scale use of herbicides is not intended; <br />however, they have a high level of utility when controlling problem perennial weeds in permanent <br />revegetation areas requiring reseeding, or where elimination of competing vegetation in a shrub <br />establishment area is critical. Any herbicides used will be based on recommendations in the most <br />current Colorado Weed Control Guide issued by the Colorado State University Cooperative <br />Extension Service and as listed in the Seneca Coal Company Weed Management Plan Qanuary 2005). <br />The herbicides will be registered for the use intended and will be applied by certified applicators with <br />strict adherence to the label. An herbicide application program has been in -place at the Seneca II <br />• Mine and the program at the Yoast Mine will be closely patterned after it. Weed control and <br />herbicides are discussed later in this tab. <br />Seed Mixes and Planting Lists. Three seed mixes have been developed for permanent revegetation. <br />Complimenting the seed mixes used in permanent revegetation are lists of tree and shrub seedlings to <br />be used in concentrated planting areas on the mine permit area. A temporary stabilization mix and a <br />list of annual grains to be used for cover cropping complete the lists of plant materials to be used in <br />the various revegetation activities. <br />Initial considerations in the development of the permanent mixes and seedling lists included the <br />anticipated reclaimed area site conditions and the desired revegetation communities. Specific goals <br />used to develop the permanent seed mixes and seedling lists included rapid and long -term surface <br />stabilization, ease of establishment, maximum use of native species, adequate species diversity, high <br />levels of utility for livestock and wildlife, good forage production potential, compatibility with <br />naturally regenerating native species present in replaced topsoil, and the ability to be self - sustaining or <br />compliment successional processes in the reclaimed plant communities. Attainment of these goals, in <br />• tum, facilitates achievement of the postmining land uses. <br />PR -02 8 Revised 01/06 <br />
