outlined below. All disturbed areas will be seeded during the first suitable planting period following final grading. Plant Species and Seeding Rates The two permanent seed mixtures proposed in this permit application were previously approved for use by the Division on nearby mining disturbances. Plant species proposed for the perennial mixtures have a documented history of meeting or exceeding the performance standard requirements of Rule 4.15. The land use designations delineated on Map 3, of Volume 5 shall dictate where a particular seed mixture is planted. Existing disturbed areas will be seeded with the Pastureland seed mixture. Depending on availability, either the pastureland or cropland mixture will be utilized to rapidly stabilize critical areas. Examination of the proposed perennial seed mixtures reveals that TCC desires to utilize introduced species for which regulatory approval is required. A summary of the two mixtures proposed for revegetation is set forth below. Cropland Mixture At this time, none of the cropland has been disturbed. However, Twentymile Coal Company has proposed a seed mixture for reestablishing cropland which contains five perennial species of exotic origin, as shown in Table 26, Cropland Seed Mixture. A seeding rate of 12 pounds, bulk seed per acre, is prescribed for areas to be reclaimed as cropland, if any cropland is disturbed. The introduced species included in the cropland mixture are documented as being of superior utility for forage production and are recommended for dryland hay by numberous researchers including Steward (1973), Seamonds and Roehrkasse (1974) and Marquiss, et. al., (1974). Pastureland Mixture The proposed pastureland mixture consists of 9 introduced and 2 native species, as shown in Table 27, Pastureland Seed Mixture. These species are of the same seasonal variety as were found on the site 2.05 -39 Revised 12/11/87
