<br />compatible with the post-mining land use, and will meet all the requirements of <br />this Rule (4.14.2(2)). <br />F. The Division does not approve terrace outslopes which are steeper than 2h:1 v <br />(50%). The Division does not approve of the retention of a highwall as a part of a <br />terrace. (4.14.2(2)(c)) <br />G. Small depressions in the backfill may be used to minimize erosion, create or <br />enhance wildlife habitat, conserve soil moisture, and promote revegetation. The <br />Division approves their construction.(4.14.2(3)) <br />H. The Division approves the applicant's plan for disposal of debris, acid-forming or <br />toxic materials, or materials constituting a fire hazard in a manner designed to <br />prevent contamination of ground or surface waters. A contingency plan has also <br />been developed to prevent sustained combustion of flammable <br />materials.(4.14.3(l)(a)) <br />The Division approves the method and design specifications for covering of <br />acid-and toxic-forming materials in order to prevent leaching into surface and <br />ground water and to insure backfill stability.(4.14.3(2)) <br />XI. Revegetation <br />A. The Division approves the use of introduced species in the reclamation seed mix. <br />The applicant has submitted information which shows that the introduced species <br />are desirable and necessary to achieve the approved post-mining land use, and are <br />not poisonous or noxious. The introduced species is Winter rye, which is included <br />to act as a nurse crop until the perennial species become established. (4.15.2(3)) <br />B. The Division approves the use of straw mulch as a means to meet soil stabilization <br />requirements. The applicant will use a interim seed mix (Table 2.05.4-4) for areas <br />that will be temporarily revege[ated. (4.15.4) <br />C. Methods to measure herbaceous cover and production, species diversity, and <br />woody plant density are discussed in section 2.05.4 of the permit. These <br />techniques include comparison of the revegetated communities with extended <br />reference areas. The Division approves ofthesetechniques.(4.15.7(I)) <br />D. Comparisons between reclaimed and undisturbed areas, in order to demonstrate <br />that success criteria of 4.l 5.8, 4.15.9, or 4.15.10 have been met, will be based on <br />the following: <br />For grassland areas, success will be demonstrated for cover and production when <br />the reclaimed area is at least 90 % of the reference area and meets the 90% <br />confidence interval using aone-sided T-test. No woody stem density standard <br />zi <br />
