• There are no groundwater rights within the Southfield loadout, adjacent <br />or immediately down - gradient areas. Essentially all groundwater in the <br />loadout area enters the surface water system within a fairly short <br />distance of the coal loadout, becoming part of Arkansas River surface <br />flows. <br />Within the groundwater basin, beneficial use is generally confined to <br />surficial colluvial /alluvial deposits, perched groundwater tables in some <br />of the upper stratigraphic units and the Trinidad Sandstone. The <br />Southfield operations will not directly impact any of these units or <br />existing associated water users. In addition, Southfield's underground <br />operations are effectively hydrologically isolated from both the upper <br />stratigraphic units and the Trinidad Sandstone by approximately three to <br />four hundred feet of relatively impermeable interbedded and cross - bedded <br />siltstones and shales. <br />• EFCI has obtained the right to utilize groundwater resources from the <br />Corley Mine Well for mine consumptive use. This well intersects the <br />abandoned Corley Mine workings in the Rex Carbon coal seam at a depth of <br />approximately 450 feet. Given the limited pumping rate, the storage <br />capacity of the underground workings, and continuous recharge, it is <br />unlikely that continued consumptive use will result in dewatering of this <br />well. In addition, the well and reservoir area are outside of the angle <br />of draw limits and should not be effected by mining or any consequent <br />subsidence. <br />Monitoring Program <br />EFCI currently maintains and will continue a comprehensive program to <br />monitor surface and groundwater quality and quantity for the duration of <br />the proposed mining, processing, and reclamation operations. The <br />monitoring program serves as an integral part of EFCI's efforts to protect <br />the hydrologic balance by providing an accurate and timely method of <br />identifying and quantifying any possibTe concerns with respect to surface <br />and groundwater resources. <br />2.05.6 -51 <br />
