Background Descri tion <br />' 1. Topography <br /> The topography of the Logan Wash area is shown in Figure 5 and consists of <br /> long, finyer-like, level benches bowided by uniformly steep (70 to 90't~) slopes. <br />' Drainages have rvorked headward, dissectiny Tertiary formotions, into the <br /> southernmost remnants of the northward-retreating Roan Cliffs. The resulting <br /> slopes include all directions of exposure. The area has a togogra,hic relief <br />' Hf about 4000 feet, ranging from 4390 feet along the Colorado River to F951 <br /> feeC at the high HHint on the plateau. On the Logan Wash site itself, the <br /> elevation ranges approximately from 6000 feet to 3600 feet. Drainage bottoms <br /> contain alluvium, and talus lies against the base of the slopes. The talus <br />' is typically no steeper than about 37 degrees. <br />' 2. Industry <br /> There is no industry on or near the Logan 4Jash site other than the Occidental <br /> In~oject itself. The nearest towns to the site, DeBeque and Grand Valley> also <br />' contain no industry. These towns are described in more dcCail belo~,+. <br /> 3. hyriculture <br />' The only agricultural activity on the Logan Wash site is a limited amount of <br /> cattle grazing in the sun~,mer. <br />t Er.tensive background information has been obtained in the flora present nn the <br /> site. One hundred eighty-`our species of vascular plants were recorded Hn the <br /> Logan 'dash property. These include 7 trees, 25 shrubs, 16 grasses, 134 fortis, <br />' and 2 succulents. Plinety-one percent of the plant species are native to the <br /> site. There are ten vegetation conrnrunities on and near the site. The vege*_ation <br /> is typica', of the Roan Cliffs. <br />' <br /> Raw shale re~noved from the retorts is deposited upon the surface and :rill he <br /> reclaimed in accordance with the requirements of the Mined Land Reclamation <br /> Board. That Beard approved a life-of-the-n•ine permit for the Loyan l•Jash operation <br />' on htarch 2, 197;. Spent shale is not brought to the surface and does r,ot need <br /> to he vegetated. <br />' Detailed information concerning topography, water, wildlife, soils and vegetation <br /> ~•+as submitted to Lhe Mined Land Reclamation !;Hard; must of that inforr.mtion is <br /> summarized in this Exhibit 4 or elsewhere in the application to which this Exhibit <br />' is attached. <br /> 4.
