<br />-3- <br />5. The hydrologic conditions within the reclaimed spoils at the Utah Tract <br />have not been discussed in detail within the permit revision application. The <br />applicant states on page IV-165 that two test borings were drilled within the <br />reclaimed spoils area. Casing was installed in the boreholes and both <br />boreholes were essentially dry. These borehole locations should be plotted on <br />a map of the area and included in the appliation along with supporting <br />documentation on the drilling and occurrence of water at theses sites for <br />review and evaluation by the Division. This information is being requested in <br />order to better understand the ground water hydrology within the reclaimed <br />spoils and to enable predictions to be made of impacts resulting from <br />subsidence of a portion of the reclaimed surface mined area. <br />6. The applicant should include in the permit revision application well <br />construction summaries for all monitor wells that are included in the <br />hydrologic monitoring program. This information should include well depths, <br />design (including perforated intervals), casing type, casing Freight above <br />ground surface, and surface elevations. <br />/ph <br />cc: Ed Bischoff <br />Jim Pendleton <br />Doc.
