Box 700 <br />Henderson, CO 80640 <br />RE: Stagecoach Pit, DRMS Permit No. M- 1983 -067 <br />Problem cited in the August 14, 2014 inspection report <br />Response to Operator's letter of September 5, 2014 <br />Dear Mr. Frei: <br />The Division of Reclamation, Mining and Safety (DRMS) received your letter on September 5, 2014. In <br />the interim DRMS believes the activities described in the letter may mitigate elevated lake elevations in <br />Zigan Lake. Although DRMS agrees that a technical revision is not required for the activities described <br />in the letter, DRMS does not believe the activities proposed in the letter will relieve groundwater <br />mounding against the slurry wall in the area between the Stagecoach Pit and Brannan's Pit 29. DRMS <br />will contact you shortly under separate cover to address groundwater mounding against the slurry wall. <br />If you need additional information please contact me at the Division of Reclamation, Mining and Safety, <br />1313 Sherman St., Room 215, Denver, CO 80203, by telephone at 303 - 866 -3567, extension 8131, or by <br />email at Tyler.
