potential for any effect on the quality of water in Big Salt Wash as a result of this <br />operation. <br />It is appazent from this discussion that the potential for diminution of quantity and quality <br />of water supplied to the Big Salt Wash potential alluvial valley floor would be minimal. <br />The Division finds that there will be essentially no effect of the operation on the <br />hydrologic character of the Big Salt Wash drainage system. <br />Grand Valley Coal Company has established surface water monitoring stations upstream <br />and downstream of the confluence of Munger and East Salt Creeks. Additionally, Grand <br />Valley Coal Company will monitor mine inflows, mine discharges, ground water <br />downgradient of the waste rock pile, coal processing waste pile and central facilities area, <br />and ground water in the alluvium of East Salt Creek. The monitoring system established <br />by Grand Valley Coal Company will be sufficient to verify conclusions of the Division <br />with respect to the effect of the operation on water quality and quantity and will indicate <br />if any problems arise which may require mitigation. <br />Therefore, pursuant to 2.06.8(5)(iii), the Division finds the proposed operation will not <br />materially damage the quantity and quality of water in surface and ground water systems <br />that supply alluvial valley floors or portions of alluvial valley floors. <br />Alluvial Valley Floor Findings In Regazd to Preserving Essential Hydrologic Functions <br />The potential for any effect of surface water quality and quantity th East Salt Creek was <br />previously discussed. Even though the potential for impact is minimal, Grand Valley <br />Coal Company has established a monitoring network to verify these projections and to <br />identify detrimental effects if they were to occur. This monitoring network is established <br />to detect changes in surface and ground water within the alluvial valley floor. <br />Upon termination of mining operations, all mine surface facilities will be removed, coal <br />material will be disposed of, topsoil will be spread, all openings will be sealed and a <br />stable, protective stand of vegetation will be established on the area. <br />Therefore, pursuant to Rule 2.06.8(5)(iii), the Division finds that the proposed surface <br />coal mining and reclamation operation will preserve, throughout the mining and <br />reclamation ;process, the essential hydrologic functions of the alluvial valley floor. <br />AVF Findinp~ <br />The Division has determined that an alluvial valley floor exists within the affected or <br />adjacent area. Therefore, the following findings are in order for the alluvial valley floor <br />known as East Salt Creek located in Township 7 South.
