Specifically, this <br />technical revision seeks to change the design of the temporary portion of the West <br />Taylor out -of -pit spoil pile. The requested changes are the result of optimization <br />studies performed on earthwork handling for the South Taylor Pit. <br />TR -98 updates Map 45 — South Taylor Fill to reflect a revised footprint for <br />temporary out of pit spoil on the West Taylor Fill. Colowyo is revising this <br />configuration to optimize ramp access to the G8 coal seam. Redesign of the <br />temporary out -of -pit spoil on the West Taylor Fill will eliminate 19 acres of <br />previously planned and approved disturbance that will occur if the original design is <br />constructed. <br />Also included with this revision is a revision application, a change of index to ease <br />incorporation into the permit document, a Geo- Technical Report from Shannon and <br />Wilson, and a copy of the proposed public notice. <br />A drawing titled "TR -98 Spoil Pile, Figure 1" has been provided with this package. <br />This map is for review purposes only and is not intended to become part of the <br />permit. It depicts the new temporary out -of -pit spoil pile superimposed over the <br />currently approved temporary spoil pile. <br />If you should have any additional questions or concerns please feel free to contact <br />me at your convenience at (970) 824 -1532. <br />A Western Fuels - Colorado, 1.LC mining property <br />Jan, <br />Mining anc: _.� <br />
