The surface water hydrology model included with TR-23 demonstrates that the <br /> plastic liner is not necessary in the ditch. Operationally for New Horizon North Mine, it is <br /> no longer necessary to be in the ditch either. <br /> Included in this technical revision are a revision application, a proposed public notice, <br /> and a change of index sheet to ease incorporation of this technical revision into the permit <br /> document. If you should have any additional questions or concerns, please feel free to contact <br /> Tony Tennyson at(970) 824-1232 or son lristategt.org. <br /> Sincerely, <br /> / Z2� <br /> Daniel J.
