provided on Figures 2.2-6, 2.2-7, and 2.2-7A. These materials have been reviewed by <br />the Division for compliance with the Rules and Regulations. <br />Between 2004 and 2007, the operator disposed of waste material generated by operations <br />at the adjacent McClane Canyon Mine, within the coal waste disposal site in the Munger <br />Canyon permit area. Waste consisted of coal fines and, rock fragments, including <br />material from yard cleanings, areas of low quality coal, rock slopes and roof falls. <br />Characteristics of the waste material were assumed to be similar to coaly material from <br />the Loma Loadout that was placed at the base of the Munger portal bench cut slope in <br />2001, based on data in Tables 4.2-1 through 4.2-3 of the PAP, and further based on the <br />fact that the McClane Canyon mine was the source of the coal at the Loma Loadout. <br />Material strength parameters, placement and compaction specifications, and a stability <br />analysis summary is provided in Section 2.2.5. A slope stability analysis with <br />assumptions is included in Appendix N. <br />The maximum capacity of the waste disposal site was originally projected to be <br />approximately 46,600 cubic yards. However, disposal operations ceased much earlier <br />than originally anticipated, and final capacity of the disposal site was less than 5,000 <br />yards of material. The waste pile was fully reclaimed in 2007 (graded, compacted, <br />cover soiled, topsoiled, and seeded). Perimeter ditches have been constructed to design <br />specifications as necessary to safely divert upland flow away from the disposal area and <br />to direct disturbed drainage to the sediment pond. <br />The applicant has supplied a description of the geology of the permit and adjacent areas <br />in Sections 4.2 and 4.3 of volume I of the application. <br />The applicant has submitted geochemical and physical analyses of the roof, floor and coal <br />for the Cameo seam from the McClane Canyon Mine (Tables 2.1-4, 2.1-5 and 2.1-5a, <br />Volume I, McClane Canyon permit application), roof and floor analyses for the Cameo <br />and Upper Carbonera seams from the Munger Canyon Mine (Tables 4.2-1, 4.2-1A and <br />4.2-113, Volume I, Munger Canyon permit application). In addition, in 2001 the operator <br />submitted geochemical and physical analyses of coal waste material from separate <br />composite samples taken from the coal stockpile yard areas at the Loma Loadout and the <br />McClane Canyon Mine (Table 4.2-3). The data from the McClane Mine roof, floor, and <br />coal, and the coal yard area samples are representative of material placed in the coal <br />waste disposal site in the Munger Canyon permit area. <br />The following specific findings are required: <br />1. The Division has approved plans for use, construction and maintenance of a <br />coal mine waste disposal area, within the Munger Canyon Mine permit area <br />(4.10.1 (1)). <br />2. The application includes plans for disposal of mine waste materials generated <br />by activities outside the permit boundary, within the coal mine waste disposal <br />site in the Munger Canyon Mine permit area. These materials include coal waste <br />25 <br />
