~II ~I~~I~~I~~~~~~I~ United States Department of the Interior OFFICE OF SURFACE MINING Reclamation and Enforcement BROOKS TOWERS 1020 15TH STREET DENVER, COLORADO 80202 June 12, 1986 Mr. David Shelton, Director Colorado Mined Land Reclamation Division Department of Natural Resources 423 Centennial Building 1313 Sherman Street Denver, Colorado 80203 Dear Mr. Shelton: ~. r;f~ ~-... .kJ ~ ... n!J JU~~ 1" 1986 The Office of Surface Mining Reclamation and Enforcement, Western Technical Center (OSMRE/WTC), has received the technical and minor revisions for the Trapper Mining Company Trapper mine in Colorado from Trapper Mining Company (list enclosed). These were all received by this office on May 21, 1986. OSMRE/WTC has determined that the revisions in the enclosed list do not constitute a modification to the approved mining plan under 30 CFR 746.18. Based on our review, OSMRE/WTC concurs with the Colorado Mined Land Reclamation Division's (MLRD) decision to approve these submittals, and the Federal permit CO-0013 dated April lye3, is revised accordingly. However, technical revision number 24 - increase in disturbed area within the permit boundary and slight change to postmining topography, requires a mining plan modification under 30 CFR 746.18(d)(1) pursuant to 746.13(b), (d), (e), (f). The April 1y83 mining plan approval by the Assistant Secretary for Land and Minerals was based on a concurrence by the Minerals Management Service that limited the approval to the end of 1985• Detailed information was only availsble for the then proposed 5 year period requiring s limited mining plan approval under 30 CFR 746.17(x). The Colorado and Federal permit approvals were similarly limited. The Colorado MLRD approval specifically stated that their permit did not carry the right of renewal as specified in 30 CFR 774.15 and Colorado MLRD Rule 2.08. In order to review a mining plan to recommend approval by the Secretary's office, OSMRE concentrates on the operation and reclamation plan. It is important for this review that all maps include township, range and section identification. The applicant should resubmit these maps. Revised map M12 indicates that a topsoil stockpile and access road were constructed in Section 5, T.SN., R. 91 W. This area is partially within a prairie falcon buffer zone for which the U.S. Fish and Wildlife Service prohibited activity between March 1 and July 31. The applicant should be aware that no activity is allowed within the buffer zone during that period.
