RULE 2 PERMITS <br />__- -~ ____ a_. _ __ ~,~~ <br />____ __ _ _..~-~~ ._~ _ ~_.-~. ~_ ~...rt..~~__ <br />• Summary of the Probable Hydrologic Consequences -South Taylor Pit <br />The anticipated probable hydrologic consequences of mining coal as proposed in this application are: <br />• Springs near the South Taylor Pit might experience increased and/or decreased flow. <br />• The South Taylor pit will eliminate several seeps and springs. <br />• Dewatering of the pit is not anticipated. <br />• Hydraulic transmissivity within the backfilled pit will be higher than the adjacent unmined areas. <br />• Base flow in Good Spring Creek will be reduced by up to 7% during and for 45 yeazs after <br />mining. <br />• Total dissolved solids in the base flow of Good Spring Creek will increase by 1.6% to 13.5% for <br />several hundred years after mining has been completed, with sulfate the dominant increasing ion. <br />• Base flows of Taylor Creek will not be reduced, and peak flow of Taylor Creek will be reduced <br />2% by the South Taylor pit. <br />• No other statistically significant changes to surface water quality or quantity are anticipated. <br />These consequences aze discussed in the following subsections. <br />• <br />• <br />South Taylor/L.ower Wilson-Rule 2, Page 110 Revision Date: 3/30/07 <br />Revision No.: PR-02 <br />
