2) Subsoil: The subsoil at all three sites consists of <br />'y weathered material from the Williams Fork Formation, comprised of <br />laminated sandstones, siltstones, mudstones, shales, and coal <br />seams. The Rienau #2 Mine was located in the "G" Seam and the <br />Northern #1 Mine was located in the "FF" seam. Both seams are <br />similar in quality, as described in the geology section of the <br />permit. Inferences regarding the subsoil material can also be <br />made from the roof and floor analysis of both seams. This <br />analysis is included from a drill hole that was cored through <br />both seams, which shows no acid or toxic forming material and <br />nothing which would seriously deter re-vegetation. The refuse <br />area consists of coal refuse followed by a 3.0 feet thickness of <br />non-combustible fill (subsoil from the minesites), followed by <br />1.0 to 1.5 feet of topsoil. To normal rooting depth, therefore, <br />the subsoils are similar and will not deter plant development. <br />This is verified by the similar plant development at the three <br />sites. There is no reason to believe that the subsoils at any of <br />the three sites are non-homogeneous, even in small areas. <br />3) Proximity and C1 imatic Conditions: Exhibit C-7 <br />shows that all three sites are within 1.3 miles of each other and <br />vary in elevation from a low of 6920 feet at the Rienau site to <br />7200 feet at the Northern #1 site. <br />4) Land Use: The pre-mining use of all areas before <br />disturbance was grazing and wildlife habitat. The post-mining <br />land use of the areas to be re-vegetated are also grazing and <br />wildlife habitat. <br />5~ Reseeding and Reveaetation: The reseeding, mulching <br />and fertilizing took place in October of 1986 for all areas <br />requested for bond release. The same company was contracted to do <br />all work. All mulching and fertilization requirements were <br />identical and the seeding mixtures are nearly identical. The <br />enclosed seed mixtures describe the small differences, which are <br />definitely not large enough to deem the areas non-homogeneous. <br />6) Erosional Conditions: A detailed site inspection at <br />all three locations shows that no rills or gullies exist at any <br />of the sites. In fact, no problem with rills or gullies has ever <br />been experienced at the sites. The good vegetation cover has <br />
