-17- <br /> not applicable to the present situation. An additional finding which must be <br /> made in order to allow surface facilities to be located within 100 ft. of the <br /> White River is -that "the operations reclamation plan provides for the <br /> reestablishment of appropriate riparian vegetation. " The approved <br /> revegetation plan for the Deserado Mine provides for the reestablishment of <br /> several different plant communities over disturbed areas during final <br /> reclamation, including appropriate riparian vegetation along the shore of <br /> Kenney Reservoir in the area of the alluvial well field disturbance has not <br /> been provided. Therefore, all findings required by Rule 4.05.18 have been <br /> made and the operation is granted approval by the Division to locate the <br /> alluvial well field facility within 100 feet of the White River (Kenney <br /> Reservoir). <br /> The operation is in compliance with the requirements of this section. <br /> VI. Hydrologic Balance: Ground Water - Rules 2.04.5, 2.04.5(7) , 2.05.6(3) <br /> an <br /> Information pertaining to ground water is presented in Sections II.C.3 and <br /> II.C. 5 of Volumes 1 and 2 of the Deserado Mine permit application. Map 4 of <br /> Volume 5 of the application depicts the geology of the mine plan area. <br /> The Deserado Mine plan area is located in the White River Basin, the eastern <br /> of the larger Uinta Basin which extends from northwest Colorado into eastern <br /> Utah. Structure and local topography are the main factors which control <br /> ground water movement in the area. <br /> Three stratigraphic units were defined in the Deserado Mine area, each of <br /> which possessed potentially different hydrologic properties. The Lower <br /> Sandstone Facies of the Mesaverde Group consists of the upper part of the Iles <br /> Formation which is predominantly sandstone with few discontinuous coal beds. <br /> The top of the Lower Sandstone Facies is the "B" Horizon. Immediately <br /> overlying the Lower Sandstone Facies is the Siltstone and Coal Facies which <br /> consists of the Lower Williams Fork Formation. This zone consists of <br /> siltstone, the coals of interest, sandstone, and carbonaceous shale. <br /> Overlying the Siltstone and, Coal Facies is the Upper Sandstone Facies which is <br /> located in -the Upper Williams Fork Formation. This stratigraphic zone <br /> consists of channel sandstones and shale/mudstone sequences. The sandstones <br /> that occur in each of these three zones yield small quantities of water due to <br /> the high percentage of fine's which fill the pore spaces. <br /> In addition to the three bedrock stratigraphic zones, alluvial deposits along <br /> the White River and at the mouths of Red Wash and Scullion Gulch were <br /> investigated to determine the nature and extent of ground water occurrences. <br /> In addition to drilling test wells into and examining the potential for <br /> bedrock aquifers, five alluvial wells (see Plate 1 ) were drilled' for both <br /> monitoring and testing. In addition to these wells, data was also obtained <br /> from the well next to the buildings in the mouth of Scullion Gulch (Staley <br /> House Well ) and from an existing well east of the buildings in the alluvium of <br /> the White River. <br /> I <br />
