VI. Coal Mine Waste Banks The Division has approved plans for use, construction and maintenance of a coal mine waste disposal area (4.10.1 (1)). 2. The applicant has submitted a plan for disposal, at the approved disposai area within the permit boundary, of mine waste materials generated by activities outside the permit boundary. These materials include waste piles at other mines. The applicant has demonstrated `.hat disposal of such materials will not adversely affect water quality or flow, vegetation, public health, or stability of the disposal area based on hydrologic, geotechnical, physical, and chemical analysis. Therefore, the Di~aision has approved disposal of these materials (4.10.1(2)). 3. The disposal area will be inspec*.ed quarterly by a qualified professional specialist under the direction of the professional engineer, experienced in construction of similar earth and waste structures. Inspection by this person has been approved by the Division as appropriate (4.10.2(1)). 4. An alternative subdrainage system for the coal mine waste area has been proposed. The Division finds that such an alternative will ensure the applicable static factor of safety, stability of the fill, and protection of the surface and groundwater (4.10.3(5)). 'JII. Backfilling and Grading The Division has approved a variance from meeting approximate original contour for reclaimed arias located at the lower Hubbard Creek area and at the bear Creek facilities area (both areas are pre-1ar+ disturbance). The Division has approved a modification in the general grading requirement<_ of 4.14.2 since sufficient spoil ~.vill not be a•iailable (4.14.2(1)). VIII. Reveaetation The Division ha> approved the use of introduced species in the reclamation seed mix. The appiicant has submitted information ~.vhich sha:+s that the introduced species are desirable and necessary to achieve the appra~ed post-mining land use, and are not poisonous or noxious (4.15.2). 2. The Division has approved the usz of mulching with straw at the rate of 4,000 pounds per acre crimped in on slopes less than 3H:1V. On steeper slopes, hydremulch or straw held down :with nettino will be used as a means to meet soil stahilization requirements (4.15.4). 3. ~4ethods to measure herbaceous cover and production, species diversity, and ~.+oody plant densicv are discusszd in Appendi:< H of the permit application. These techniques include the point intercept method for determination of cover and clipping ;,f _17_
