~ L Division of Wildlife recommendations. The species diversity standard is based on a comparison of pre-mining and post-mining life-form contribution to the vegetation community. Two minor revisions affecting the revegetation plan have been approved since Permit Revision No. 1 approval. Minor Revision 17, approved April 1, 1985, allowed a discontinuance of woody seedling planting in favor of direct seeding of woody species on the East Pit reclaimed area. Minor Revision 24, approved October 27, 1986, allowed three seed mix modifications. The modifications allowed a one-time-only addition of winter wheat to the East Pit Area, permanent additions of smooth brome to the East Pit mix, and big bluestem to the Barren Ridge mix. The permittee has stated that herbicides and/or pesticides will be used according to U.S. Forest Service practices (page 2.05-45 revised October 14, 1983, Federal Lease permit revision application). The permittee has submitted information on threatened or endangered plant species at the mine site. No listed or proposed listed threatened or endangered plant species has been identified during vegetative surveys. At this time, pursuant to Rule 2.07.6(2)(n), the Division finds that the reclamation activities will not affect the continued existence of any threatened or endangered plant species or result in the destruction or adverse modification of their critical habitats. VII. Post-Mining Land Use A. The pre-mining land use in the area of the Chimney Rock Mine included rangeland, pastureland, and wildlife habitat (Map 2). Technical Revision No. 21, approved by the Division, USFS, BLM and the DOW on December 4, 1990, changed approximately 50 acres of privately owned land from rangeland to pastureland. The operator has reclaimed the East Pit Area to dryland pasture, the Barren Ridge Area to rangeland, and the Federal Lease Area to wildlife habitat. Surface landowners have indicated agreement with the proposed land uses. VIII. Protection of Fish, Wildlife and Related Environmental Values A. The applicant has proposed the use of persistent pesticides on the site during reclamation operations. The Division proposes to approve this usage (4.18(4)(9)). B. Fish and wildlife habitat is a planned post-mining land use. The applicant has selected appropriate plant species and distributions to benefit fish and wildlife (4.18(4)(1)). IX. Operations on Alluvial Valley Floors A. The Division has determined that an alluvial valley floor exists within the affected or adjacent area. Therefore, the following -16-
