No threatened or endangered species of plants aze known nor aze any likely to occur on the permit area based upon known habitat requirements of endangered or threatened potential occupants (See Appendix 4-6). A survey was conducted pursuant to a stipulation of the permit and no endangered or threatened plant species occurred within the permit azea. No threatened or endangered species of wildlife aze known to exist on the pernrit azea. Bald eagles winter in trees along the Animas River adjacent to the new covered shopping mall (Map 4-7). The winter resident eagles feed upon carrion and appazently upon mule deer road kills along State Highway 160. It is believed that this activity will continue due to the density of traffic in this area. The major impact of the mine operation is the reduction of some big game winter range. The total project will remove approximately 105 acres from the production, but due to on-going reclamation of backfilled azeas of the pit and maxnnum disturbance at any one time is estimated at about 75 acres. Golden Eagles aze not expected to be impacted to the same degree as Bald Eagles since it is assumed from experience with resident Golden Eagles in other areas of Colorado that they aze not obligatory winter carrion eaters. The permit azea does not offer good roost sites or nesting habitat. The permit azea does offer suitable hunting grounds which may be enhanced when they aze opened up and resident rodents and rabbits aze displaced. The open nature of the proposed revegetated azeas should offer improved hunting habitat (also applies to other rapture species) until, through succession, the azea returns to a predominantly pinyon juniper climax community. New powerline construction undertaken by OEI will be in conformance with REA Bulletin 61-10 to prevent rapture electrocution. To the degree that the concerns of the DOW can be accommodated by the requirements of the post-mining land uses, the fish and wildlife plan for the reclamation of the mine will do so. 2.05.6(3) Protection of the Hydrolo¢ic Balance Appropriate maps and cross sections relative to the ground water and surface water hydrology have been provided in Section 2.04.7. Backfilling, grading, retopsoiling, and subsequent revegetation will re-establish landforms consistent with those adjacent to the mine. Surface water runoff and attendant erosion will be minimised through establishment of vegetation. The predominantly herbaceous nature of the vegetation to be established will ultimately provide greater cover and erosion control than the native pre-mine vegetation. The Carbon Junction Mine will minimally impact both the quality and quantity of ground and surface waters. A discussion of the probable hydrologic consequences of mining is set forth below as well as in the CDMG findings document for the initial approval of permit C-92-080. The CDMG discussion of probable hydrologic consequences is incorporated by reference into this document. This discussion includes a quantitative analysis of the TR08, TRll (v 1.0) 5-51 Revised 9/97, 8/02
