I Mayo and Associates, LC <br />1.1 Objectives <br />The specific objectives of this investigation are: <br />1. Prepare a compazative analysis of the geologic and hydrogeologic conditions <br />responsible for the major types and magnitudes of groundwater inflows associated <br />with coal mines in the Wasatch Plateau and Book Cliffs, Utah, and the Somerset <br />azea, Colorado, <br />2. Based on E Seam geologic information provided by MCC, utilize the comparative <br />analysis as a framework for evaluating the potential hydrologic conditions which <br />maybe encountered during E Seam mining activities, and <br />3, Estimate the general conditions and potential magnitudes of groundwater inflows <br />that maybe encountered during E Seam mining. <br />This report is organized as follows: <br />1. Comparative analysis of groundwater inflows <br />• summary of the Geologic conditions <br />• styles of groundwater inflows <br />2. Analysis of potential E Seam hydrogeology <br />3. Estimation of potential mining related groundwater inflows <br />1.2 Sources of Information <br />Known groundwater inflows and their associated hydrogeologic conditions were <br />compiled and summarized using information obtained from public domain documents, <br />including: reports and investigations published by the U.S. Geological Survey, Colorado, <br />Evaluation of Potential Groundwater Inflows 10 February 24, 2004 <br />Associated with E Seam Mining, <br />West Elk Mine, Somerset, Colorado <br />
