Issues previously addressed are not included in this letter. <br />2. The SEDCAD for watershed 21 has been revised to account for the area now <br />disturbed within the watershed. The oew run should be placed in Exhibit 66. <br />DCW-1 was also revised with the new discharge from watershed 21. This ditch <br />design should replace the three designs in Exhibit 66. Also enclosed is a revised <br />Table 43 and 44. <br />MCC has included the discussion presented in previous response letters and the <br />discussion presented in this response letter in the permit text, which is enclosed. <br />The 2,000 - 3,000 CY of material will remain in the portal bench storage bench <br />and at the slope below the mine supply storage light-use road. These two areas <br />and the MS$ will be reclaimed such that the area will be stable, the hydrologic <br />balance will not be impacted, topsoil will be salvaged, stored and replaced, and <br />the disturbed areas will be revegetated. Map 58 and 58A show that these areas <br />will be returned to AOC. <br />6. As Map 53, Map 53B, Table 36 and Table 36A are revised for future revisions, <br />they will be updated to make the locations of topsoil stockpiles more clear. <br />7. The bond estimate is acceptable. <br />:~ <br />S' c ely, <br />Cluistine E. Johnstc <br />Permitting Specialis <br />cc: Norm Every, Phil Schmidt, Kathy Welt <br />~zodaoc <br />
