schedule due to unavoidable hazardous situations. These situations include elimination <br />of misfires, adverse weather, equipment failure, and safety related reasons (4. <br />08.3(2)(b)(v) and (4.08.4(2)). <br />VII. Disposal of Excess Spoil <br />Permit section 3.5.3, Vol. III of the application discusses disposal of excess spoil. <br />In accordance with TR106 and Appendix T, the K -Pit Buttress Fill is no longer required. <br />The Horse Gulch Fill is described in Appendix T and inspected in accordance with 4. <br />09.1(11), and meets the definitions and regulations associated with valley fill and head of <br />hollow construction. The Horse Gulch underdrain and runoff diversions were constructed <br />in accordance with Rules 4.09.2(2), 4.09.3(1), and 4.09.2(7). The slope stability analysis <br />for the Horse Gulch Fill demonstrates that the fill is designed to meet rules (4.09.1(7)) and <br />(4.09.2(1)). <br />VIII. Coal Mine Waste Banks <br />No specific approvals are granted to the applicant under this section. <br />IX. Coal Mine Waste <br />No specific approvals are granted to the applicant under this section. <br />X. Backfilling and Grading <br />Backfilling and grading are discussed under Section 3.5, Vol. III of the permit <br />application. <br />1. The applicant is bonded for a maximum of four (4) spoil ridges at any <br />time within each pit area. Reclamation has historically been, and is proposed for <br />completion, at approximately the same rate as disturbance of any new ground <br />(4.14.1). <br />2. The post -mining topography map (annual reclamation map) is a permit <br />requirement in permit section 3.5.3. <br />XI. Revegetation <br />The Division previously approved Trapper's revegetation plan as set forth in permit <br />Section 3.6, Vol. III of the application. <br />1. The applicant uses introduced species in the reclamation seed mix, and <br />submitted information illustrating the desirability and necessity of introduced <br />species in achieving the approved post -mining land use illustrating that these <br />species are not poisonous or noxious (4.15.2). In conjunction with Trapper's <br />years of reclamation experience, Trapper has reduced the number of introduced <br />species in the seed mixes utilized at the site. DRMS found the seed mix <br />adjustments acceptable. <br />2. Methods to measure species diversity, woody plant density, herbaceous <br />cover and production are discussed in permit section 4.4.1, Volume IV. Seed <br />mixes and revegetation practices are designed to meet diversity standards set forth <br />20 <br />
