reclaimed area in 2005 and 2006, along with interseeding of the treated areas <br /> following the second treatment. The interseeding was completed in February 2007. <br /> The Division approved further amendments to the revegetation plan and success <br /> evaluation criteria in association with PR-3. Areas approved for "Industrial or <br /> Commercial" postmining land use, which are designated as "Active Area" on Exhibit <br /> 6C-A, or identified as"Steep Rock Face"on Figure 14-14 will not be seeded or subject <br /> to revegetation success demonstration. Areas approved for "Industrial or <br /> Commercial" postmining land use, which fall outside of the "Active Area" boundary <br /> of Exhibit 6C-A and are not identified as "Steep Rock Face" on Figure 14-14,will be <br /> revegetated in accordance with the approved plan, and seeded with the Table 14-8 <br /> "Upland Components" seedmix. Revegetation success for these portions of the <br /> "Industrial or Commercial" postmining land use area will be based on qualitative <br /> assessment of "ground cover sufficient to control erosion", pursuant to Rule <br /> 4.15.10(2),in association with bond release inspection and assessment. <br /> The following specific findings are required. <br /> A. The Division has approved the use of two introduced species in the current <br /> reclamation seed mixes. The species are Cicer milkvetch in the lowland seed <br /> mix and Prostrate kochia in the upland seed mix. The introduced species are <br /> desirable and necessary to achieve the approved post-mining land use, and are <br /> not poisonous or noxious (4.15.2). Introduced species comprise approximately <br /> 6.1% of the seeding rate for the lowland mix and 4.3% of the seeding rate for <br /> the upland mix, on a seeds/sq.ft. basis. <br /> B. The Division has approved the use of wood fiber, grass hay, or straw mulch as a <br /> means to meet soil stabilization requirements (4.15.4). Hay or straw will be <br /> certified noxious weed-free. <br /> C. Methods to measure herbaceous cover and production, species diversity, and <br /> woody plant density, applicable to "Fish and Wildlife Habitat" postmining land <br /> use areas,are discussed in Section 2.05.4,Tab 14,Volume 5,of the permit. These <br /> techniques include point intercept cover sampling, quadrat production, and belt <br /> transect woody plant density sampling. Appropriate methods for sample <br /> adequacy demonstration and statistical comparison are specified. Quantitative <br /> sampling techniques and comparison methods are not applicable to"Industrial or <br /> Commercial" postmining land use areas. <br /> The proposed success measurement techniques are approved by the Division <br /> (4.15.7(l)). <br /> D. Comparisons between reclaimed and undisturbed areas, in order to demonstrate <br /> that success criteria of 4.15.8 have been met, for "Fish and Wildlife Habitat" <br /> postmining land use areas,will be based on the following: <br /> 50 <br />
