<br />-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 />and <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 fines 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 />
