6/18/13 State.co.us Executive Branch Mail - Trapper Mine; C- 1981 -010; PR7 Reuiew Assistance <br />Ebert - DNR, Jared <jared.ebert @state.co.us> Tue, Jun 18, 2013 at 10:08 AM <br />To: Susan Burgmaier - DNR <susan.burgmaier @state.co.us> <br />Cc: Alysha Hernandez - DNR <alysha.hernandez @ state.co.us>, Sandy Brown - DNR <sandy.brown @state.co.us> <br />Hello Susan, <br />Trapper Mining, Inc. has submitted a permit revision application (PR7). Part of this revision is an updated Post <br />Mine Drainage Stabilization plan contained in section 4.8.1.3 in the permit. Additionally drainage <br />reestablishment is discussed in Section 3.5.3 of the permit. Rule 4.05.3(1)(e) requires that these drainages be <br />designed, located, constructed, maintained and used to minimize adverse impacts to the hydrologic balance and <br />to be stable. <br />am requesting your help in reviewing the updated information in this section to see if they meet the requirements <br />of the Rules. I am required to submit a preliminary adequacy review by July 30th, 2013. If I could have your <br />comments a week or two prior to this date that would be helpful so I can incorporate any issues you have <br />identified into the preliminary adequacy review letter. A copy of the revised pages is attached. Please let me <br />know if you have any questions. <br />Thanks, <br />Jared Ebert <br />Department of Natural Resources <br />Division of Reclamation, Mining and Safety <br />1313 Sherman Street, Room 215 <br />Denver, Colorado 80203 <br />303 -866 -3567 ext. 8120 <br />`` Trapper- 4.8.1.3.pdf <br />1604K <br />https: / /mail.g oog le.conVmai I /u /0 / ?ui =2 &i Ire29129fcb5 &view = pt &search =i nboy&th= 13f580bfl aa697d9 1 /1 <br />
