There are no coal processing facilities, nor are coal mine waste banks proposed. All of the <br />coal is transported to the power station by a transportation contractor. <br />IX. Coal Mine Waste <br />Reject rock from a rotary breaker at the power plant may be transported back to the mine site <br />and deposited at the pit at least 10 feet below the subsoil level. <br />X. Backfilling and Grading <br />A. The Division has approved the applicant's plan for disposal of acid-forming or toxic <br />materials in a manner designed to prevent contamination of ground or surface waters <br />(4.14.3(1)(a)). <br />B. Backfilling and grading of the overburden occurs simultaneously with overburden <br />removal. The generation of excess overburden is not anticipated. Map 2.05.3-1 gives <br />a cross-sectional view of the typical mining process. <br />C. Permit details on backfilling and grading are provided in Section 2.05.4(2)(c). The <br />proposed post -mining topography is depicted on Map 2.05.4-1. This map also includes <br />a series of cross sections which provide comparisons of the pre -mining ground surface <br />with the proposed post -mining elevations. <br />XI. Revegetation <br />The proposed revegetation plan is designed for the post -mining land uses of irrigated pasture, <br />cropland -irrigated alfalfa hay and dryland pasture. All revegetation plans are discussed in <br />Section 2.05.4 (2)(e). <br />A. Introduced Species <br />The Division proposes to approve the use of introduced species in the reclamation seed <br />mix. The applicant has submitted information that shows that the introduced species <br />are desirable and necessary to achieve the approved post -mining land use, and are not <br />poisonous or noxious (4.15.2). <br />Seed mixes number 2 and 3 are temporary seed mixes. Introduced species in these <br />mixes will facilitate site stabilization and provide organic matter when incorporated into <br />the topsoil prior to permanent seeding. <br />Seed mix numbers 5 and 6 are for the reclaimed irrigated pastureland. All species are <br />in these mixes are introduced and were selected as beneficial for grazing purposes as <br />discussed in Section 2.05.4(2)(e). <br />26 <br />
