Mayo and Associates, LC <br />I ~ 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 />area, Colorado, <br />2. Based on E Seam geologic information provided by MCC, utilize the compazative <br />I 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 rnining. <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 />
