<br />balance was substantiated in a leaching study conducted by Dr. Herbert Gardner who <br />is with the Science and Education Administration of the u.S. Department of <br />Agriculture at Colorado State University campus at Ft. Collins. No toxic or <br />acidic changes are expected in the ground water as indicated from the overburden <br />analyses. <br />Kerr Coal Company will dewater the Suddvth coal seam in order to strip <br />mine the coal Zn Pits No. 2 aad 3. The water Ieve1 will eventually recover with <br />time after reclamation. <br />No wells are completed in the Sudduth coal seam with in the Johnny Moore <br />Syncline and there are no discharges From the seam which are put to beneficial use. <br />Therefore Kerr's surface mining activities will not impact any water use derived <br />from the Sudduth coal seam aquifer. <br />2. The proposed surface coal mining activities will not effect the surface <br />flow or water quality of Williams and Bush Draws. <br />Kerr Coal Company is leaving a sufficient buffer zone on both William and <br />Bush Draws which will not be mined. There are no impoundments upstream and over <br />the subcrop of the units to be disturbed by mining which would produce infiltration <br />loss of flow to the pits. Water levels on Map 15a and Table 8a for alluvial wells <br />and adjacent coal seam wells, indicate that the Sudduth coal coal seam neither <br />recharges or receives water from the alluvium or the intermittent streams in <br />Williams and Bush Draws. <br />3. The proposed surface coal mining activity will effect the quantity of water <br />in Sudduth Draw. A stipulation has been attached. <br />See explanation in VI-A under the stipulation on decreasing infiltration <br />in Sudduth Draw and section on effect on ground water of Sudduth Draw in the <br />Alluvial Valley Floor section. <br />4. Kerr Coal Company will mine through a spring in the Old Sudduth Mine, <br />Section 15, T9N, R78W. Destroying this spring will not significantly effect the <br />quantity and cuality of water in Suddvth Draw and will improve the quality of <br />water in Sudduth Draw. <br />Flow in this spring has been estimated to be less than 1 gpm and is <br />supplied bu flow from the Sudduth coal seam. Water quality was not measured in- <br />directly on this spring, however, stream water samples taken below the small <br />tributary where the spring is located had a higher salt load than the sample <br />taken directly above the tributary (page 780-126a). Removal of this spring will <br />improve the water quality of Sudduth Draw. <br />However the quality of this spring is not directly monitored presently. <br />Monitoring the quality of the spring water from the Old Sudduth Mine will provide <br />the best information in the water discharging from a disturbed area which is <br />presently available. For this reason a stipulation has been attached to the <br />oermit. <br />5. The mining activities by Xerr Coal Company may significantly effect the <br />quantity of water in the spring in Section 22, T9N, R78W. This spring is presently <br />used as a stock water supply and is of great concern to the B.L.Ff. <br />-12- <br />
