CO 80x67 Division Director <br />Re: DNIG/OSM Permitting Coordination, Twentymile Coal Company, The Foidel Creek <br />Mine, DMG Permit No. C-82-056, Minor Revision No. MR-163 <br />Dear Mr. Mills: <br />The Division received your application for Minor Revision No. MR-163 on March 26, 1999. <br />This MR requests approval to widen the Third Right gate road, install the Second Right sump, <br />and describe the Fish Creek Borehole discharge treatment system. No change in reclamation <br />liability is anticipated at this stage of our review. <br />I discussed the intent of this MR with Larry Kline at OSM last week. Based on the current <br />description of the MR, OSM has determined that this IvfR is a revision that does not require <br />modification of your OSM mine plan. <br />Sincerely, <br />Daniel I.
