CO 80234 <br />Re: New Horizon North Mine (Permit No. C-2010-089) <br />Technical Revision 10 (TR -10) <br />Adequacy Review No. 1 <br />Dear Mr. Gilbreath: <br />The Colorado Division of Reclamation, Mining and Safety (Division) received your application for TR -10 for <br />the New Horizon North Mine on July 16, 2015. The application was deemed complete on July 24, 2015. The <br />Division finished its review of the application and needs clarification on the following issue: <br />The Lambert and Associates' geotechnical report provided two `moist' unit weights but it appears that the pond <br />embankment is homogeneous. It is assumed that this is a typo and that one of the numbers is the dry density <br />weight. Please clarify why two `moist' soil weights were provided. <br />If you have any questions or need additional information, please contact me at (303) 866-3567 ext 8142. <br />Sincerely, <br />Aw�4--ZI, <br />Brock Bowles <br />Environmental Protection Specialist <br />brock.bowles@state.co.us <br />1313 Sherman Street, Room 215, Denver, CO 80203 P 303.866.3567 F 303.832.8106 http://mining.state.co.us <br />John W.
