10.0 Plant Growth Media and Revegetation The Climax Mine site closure and reclamation plan is detailed in Section 10.0 of the Mining and Reclamation Permit (as amended in 1980 and 1989) and in Section 4.0 herein. Generally, revegetation plays an important role in this approved plan. While topsoil material (growth media) is not widely available to cover the Robinson and Ten Mile tailing impoundments (Mayflower impoundment has been completed), it will be available to cover visually intrusive areas along Highway 91. Such areas may include the Storke yard, the crusher and plant area yards, those aspects of the E-Dump which face the highway, and those small areas noted in the 1989 Amendment as "Interim Reclamation Areas". Detailed soils information and maps are found in Section 7.0 of the Mining and Reclamation Permit. In addition, significant research relative to soils and revegetation has been conducted at Climax since the late 1960s (Section 9.0 of the Mining and Reclamation Permit). Some of this research, including soil/vegetation test plots, are revisited periodically to determine long term trends. 11.0 Wildlife Protection • Since the initial planning process for the Climax Mine Mining and Reclamation Permit in the early 1970s, wildlife resources have been important to and recognized by Climax. Colorado Division of Wildlife (CDoW) personnel have been involved in the review of permit applications and in planning assistance with various mitigation projects such as instream habitat improvement in the upper Arkansas River. Information and data developed during permit planning is included in Section 7.0 of the Mining and Reclamation Permit. Comments and input into this permit application were solicited from the CDoW by Climax prior to the initial filing. Although wildlife issues at Climax never have been significant, Climax has maintained excellent communications throughout the years with both Regional Office personnel and the local District Wildlife Manager. A survey of the Climax site to assess the presence or lack thereof of threatened or endangered species was conducted in 1994 with negative results. A copy of this report is included in Appendix N. 11.1 Statement of Zero Mortalities During its long period of operations, the Climax Mine has not experienced or documented any wildlife mortalities attributable to its operations through exposure to process waters, designated chemicals, or acid-producing materials.
