where the species was observed by total samples. <br /> Measurement of success standards diverge between the two bond release blocks for species diversity. <br /> For the Strip Pit success of species diversity is measured utilizing the Shannon Weiner Diversity Index <br /> (H), combined with four tests; Mandatory Test A and two of the remaining three alternative tests(B, C or <br /> D),must be passed. The H value must be greater than 0.8,the four greatest species contributing to the <br /> calculated total H must exceed 48 % cover from the revegetated area, and at least four species must <br /> contribute more that 5.0% cover to H. For Mandatory Test A,no species may exceed 40%relative <br /> cover. This is a technical standard. For details on the development of the index refer to Exhibit 24, The <br /> Strip Pit Reclamation Plan and the SL4 application. <br /> Species diversity in the Utah Tract derives from the Trapper Mine technical standards. The measures of <br /> species diversity success requires at least five principle species, including a minimum of four cool season <br /> perennial grasses and one forb species possessing a minimum of 3%relative cover,with no single species <br /> exceeding 50%relative cover and no four species in combination contributing more than 80%relative <br /> cover. The species diversity requirement meets the criteria outlined in Rule 4.15.8(5). <br /> IV. OBSERVATIONS AND FINDINGS <br /> Phase I <br /> The Utah Tract is an area of reclaimed surface mine spoils overlaying portions of MCM's underground <br /> mining areas. The Utah Tract was previously reclaimed by Utah International as part of the Trapper Mine <br /> Operations. Reclamation in the Utah Tract comprised of backfilling and grading,topsoil placement, <br /> mulching and seeding. These activities were conducted by Trapper Mine between 1979 and 1983. There <br /> are no ponds in the Utah Tract. The Postmining topography is shown on Map 2 of the SL4 submittal. <br /> The majority of the Strip Pit was reclaimed in 1981,with the remainder reclaimed in 1987. Highwall <br /> slopes in the Strip Pit were reduced to a maximum of 31-1:1V,a profile configuration similar to natural <br /> drainages found within the permit area. Slopes in the reclaimed area do not exceed 33.3%(3H:IV). In both <br /> the Utah Tract and the Strip Pit contour ditches and furrows were constructed on reclaimed slopes to <br /> control erosion on the reseeded surface. These features have since filled in with sediment and blend into <br /> the reclaimed topography. Vegetation is well established and no evidence of rill, gully or sheet erosion <br /> was evident during inspection. Other than one small swale of a former stock tank,no instability or low <br /> spots prone to holding water were noted during the inspection. <br /> Compliance with Approved Post Minim Topography <br /> The Division evaluated the reclamation parcels to determine if the affected areas have been backfilled <br /> Permit Number C1981044 Page 13 of 25 <br />
