June 30, 20215 <br />Mr. Jared Ebert <br />Colorado Division of Reclamation Musing & Safety (DRMS) <br />1313 Sherman Street, Rm 215 <br />Denver CO 80203 <br />PO Box 250 <br />36600 Routt County Road 27 <br />Hayden, CO. 81639 <br />Re: Peabody Sage Creek Mine (Permit No. C-2009-087) 2015 Rill & Gully Survey and Maintenance Item <br />Locations <br />Mr. Ebert: <br />Please see the attached map from the 2015 rill and gully surveys. I have also included on the map areas where <br />maintenance or additional monitoring is needed. <br />You mentioned in the latest monthly inspection report a slump just above the portal. This is an area that we have <br />been watching for several years. I will contact the engineering department at Twentymile to assess the situation <br />and decide if any immediate action is necessary. The slump near the outlet of the upper sump is starting to grass in. <br />We will continue to monitor the area but don't feel any action is warranted since there is no threat of resource <br />damage and it will result in additional ground disturbance. The remaining items mentioned in the latest inspection <br />reports are on a maintenance list and will be repaired once the initial round of weed control has been completed. <br />If you or DRMS staff has any questions or comments, please contact me at (970) 276-7003. <br />Best regards, <br />B.
