STATE OF COLORADO 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 Interoffice MEMORANDUM to: Janet Binns COLORADO DIVISION OF RECLAMATION MINING SAFETY Bill Ritter, Jr. Governor Harris D. Sherman Executive Director from: Byron G. Walker Ronald W. Cattany subject: Eagle Mine Complex, C-1981-044, SL-2 Adequacy Responses Division Director date: January 31, 2006 Natural Resource Trustee Janet, this memorandum is in response to your memorandum of 1/13/2006, same subject. I believe the response from the applicant is adequate. Request 15 was made to provide us with a clearer understanding of subsidence observed in the area. We should be able to generate, within house, such depictions. However, in review, I do not believe we have to. I found no evidence in the PAP or the request that the subsidence features were not within the approved subsidence control plan (there were no specifics with regard to protection of rangeland). Approved postmining land uses appear to be feasible. There was no indication of material damage or requirement for restoration of renewable resource lands or structures. With regard to item 16, the applicant has responded that the areas being released are not affected by fluctuations in the mine water. Our concern was that alternate wetting and drying of the remaining coal pillars might result in collapse of more areas. The applicant has indicated that subsidence has manifested itself over the area requested for release. All materials supplied and borrowed have been returned to you. Please see me if you have any questions. Cc: Dan Hernandez (w/o encl) Office of Office of Mined Land Reclamation Denver • Grand Junction • Durango Active and Inactive Mines
