Enclosed <br />please find three copies of new and revised pages, figures, <br />tables and exhibits. These items are designed to supplement or <br />replace existing items in our permit application. <br />A description of this submission will follow the format of the <br />questions in Erica's letter and will include our response and a <br />listing of revised pages and exhibits associated with the <br />question. <br />1. Pages 203 - 205 have been revised to update our projections <br />of mine discharge on surface water quality. The projections <br />are base upon information included in recent Annual <br />Hydrologic Reports. <br />2. Revisions to pages 203 -205 include information for the <br />Roadside North Portals. <br />3. Pages 55, 80, 84, 90, 91 and 204 have been revised to show <br />another well, nearby new page Sla, but that neither well is <br />considered to be in or adjacent to the permit boundary. <br />Page vi has been revised to include reference to the new <br />Figure. Pages 66 and 67 refer to some of the City of <br />Palisade's springs as being close but again we do not <br />consider them to be in or adjacent to the permit boundary. <br />Exhibit 17 has been revised to show these wells and springs. <br />III IIIIIIIIIIIIIIII <br />sss <br />P.O.
