DIVISION OF RECLAMATION, MINING AND SAFETY Department of Natural Resources 1313 Sherman St., Room 215 Denver, Colorado 80203 Phone: (303) 866 -3567 FAX: (303) 832 -8106 June 20, 2012 Roy Karo Seneca Coal Company, LLC P.O. Box 670 Hayden CO 81639 RE: Seneca I1W Mine (Permit No. C1982057) Technical Revision No. 73 — Pond 016 Slide Remediation Request to Postpone Topsoiling and Seeding Dear Mr. Karo: The Division has received your request for postponement of topsoil redistribution and seeding of areas of the Seneca I1W Mine affected by the slide remediation work. We agree that the past winter was extremely dry and was not likely a good test of whether the remediation efforts in the Pond 016 slide area were successful. In order to ensure that topsoil resources would not be lost should a subsequent slide occur, it would be best to verify the stability of the area under normal conditions before topsoil is replaced. Therefore, the Division approves your request to delay topsoil replacement and seeding until 2013. Topsoil replacement and seeding must be completed no later than December 31, 2013. In the interim, it is imperative that Seneca Coal Company continue to control noxious weeds on the topsoil stockpile and regraded areas even though final reclamation of the areas will be delayed. The 2011 Rill and Gully Map submitted by Seneca Coal Company indicates that the Pond 016 area drainage and road would be topsoiled. The Division is aware that this will not be done in 2012; the map need not be revised. Should you have questions or need additional information, please contact me. Sincerely, Susan L.
