VI. Coal Mine Waste Banks <br />1. The Division has approved plans for use, construction and <br />maintenance of a coal mine waste disposal area. (4.10.1 (111. <br />2. The applicant has submitted a plan for disposal, at the approved <br />disposal area within the permit boundary, of mine waste materials <br />generated by activities outside the permit boundary. These <br />materials include waste piles at other mines. The applicant has <br />demonstrated that disposal of such materials will not adversely <br />affect water quality or flow, vegetation, public health, or <br />stability of the disposal area based on hydrologic, geotechnical, <br />physical, and chemical analyses. Therefore, the Division has <br />approved disposal of these materials. (4.10.1(2)1, <br />3. The disposal area will be inspected quarterly by a qualified <br />professional specialist under the direction of the professional <br />engineer, experienced in construction of similar earth and waste <br />structures. Inspection by this person has been approved by the <br />Division as appropriate. (4.10.2(111. <br />4. An alternative subdrainage system for the coal mine waste area has <br />been proposed. The Division finds that such an alternative will <br />ensure the applicable static factor of safety, stability of the <br />fill, and protection of the surface and ground water. (4.10.3(511. <br />VII. Backfillinq and Grading <br />1. The Division has approved a variance from meeting approximate <br />original contour for reclaimed areas located at the lower Hubbard <br />Creek area and at the Bear Creek facilities area (both areas are <br />pre-law disturbance). The Division has approved a modification in <br />the general grading requirements of 4.14.2 since sufficient spoil <br />will not be available. 14.14.2(111. <br />VIII. Re vegetation <br />1. The Division proposes to approve the use of introduced species in <br />the reclamation seed mix. The applicant has submitted information <br />which shows that the introduced species are desirable and necessary <br />to achieve the approved post-mining land use, and are not poisonous <br />or noxious. (4.15.21. <br />2. The Division proposes to approve the use of mulching with straw at <br />the rate of 4000 pounds per acre crimped in on slopes less than <br />3H:1V. On steeper slopes. hydromulch or straw held down with <br />netting will be used as a means to meet soil stabilization <br />requirements. 14.15.4). <br />3. Methods to measure herbaceous cover and production, species <br />diversity, and woody plant density are discussed in appendix H of <br />the permit application. These techniques include the point <br />-18- <br />
