boreholes, breathable air holes and vent degasification wells. The Division will <br />require that each hole, well, or other underground opening be capped, sealed, <br />backfilled, or otherwise properly managed (4.07.3). <br />VI. Use of ExblOsives — Rule 4.08 <br />No specific approvals are granted to the applicant under this section. <br />VII. Disposal of Excess Spoil — Rule 4.09 <br />No specific approvals are granted to the applicant under this section <br />VIII. Coal Mine Waste Banks —Rule 4.10 <br />Information pertaining to the handling and disposal of coal processing waste generated by <br />the mining operation is presented in Section IV. D Vol. 4 of the permit application. Map <br />76 exhibits the location of the 11 refuse disposal areas to be developed over the life of the <br />mine. Map 77A shows the configuration of the first five sub -areas to be developed. <br />Refuse areas RP -1, RP- 2/3/4, and RP -5A were developed during previous permit terms. <br />Refuse area RP -1 has been reclaimed; RP -2/3/4 and RP -5A are currently active. <br />Detailed design plans have not been provided for proposed future refuse disposal <br />structures. Pursuant to Rule 2.05.3(8)(ii), detailed design plans will be required prior to <br />initiation of construction of Refuse Area 513, and of subsequent refuse disposal structures <br />to be developed over the life of the mine. <br />IX. Coal Mine Waste — Rule 4.11 <br />The following specific findings apply to approved refuse disposal areas RP -1, RP- 2/3/4, <br />and RP -5A. <br />A. The Division approved plans for use, construction, and maintenance of a coal mine <br />waste disposal area. The approval was based on a demonstration that no ground <br />water exists to a depth of at least 44 feet below the refuse area, and no springs or <br />seeps are known to exist in the area (4.10.1(1)). <br />B. The Division finds that an alternative sub - drainage system for the coal mine waste <br />area is not required to ensure the applicable static safety factor, stability of the fill, <br />and protection of the surface and ground water. This is due to the demonstrated lack <br />of groundwater in the coal mine waste area (4.10.3(5)). <br />C. The permittee has demonstrated, based on physical and chemical analyses of refuse <br />material and cover soil, and vegetation field trials, that the revegetation requirements <br />of 4.15 can be met with less than four feet of cover on the coal processing waste bank <br />(4.10.4(5)). <br />37 <br />
