Section 780.16 (a) Continued. Revised 11/20/80 Tipple Area; (2) the sage grouse wintering and breeding complex associated with the Kerr Mine Area; and (3) the active golden eagle nest located approximately two miles west of the Kerr Mine Area. Since the golden eagle nest was previously discussed, only the wetland and the sage grouse will be discussed below. Wetlands. The area surrounding the Kerr Tipple Area has been iden- tified as a wetland habitat. The integrity of the wetland sur- rounding the Kerr Tipple Area will be protected through implementa- tion of the sedimentation control measures outlined in Section 816.G5. Proper maintenance of the sedimentation pond at the tipple will minimize the amount of suspended sediment leaving the Kerr Tipple Area and thereby prevent degradation of the wetland habitat. Implementation of the dust control measures described in Section 816.95 will serve to protect the adjacent aquatic habitats by minimizing the build-up of coal dust. Noise control measures, in conformity, with MSHA requlations, also will serve to minimize impacts on the wetland habitat. Management techniques to be used by Kerr Coal to protect and en- hance the environmental values associated with the adjacent wetland habitat will consist of cleaning diversion ditches and sedimenta- tion ponds whenever their effectiveness might be impaired by sedi- ment build-up. In addition, coal dust will be controlled by appli- cation of a water spray whenever dust emissions become a problem. 1 The exact importance of the Illinois and Canadian River as habitat for the Johnny darter are unknown. Propst and Corrarino (1979) documented the presence of the Johnny darter in the Canadian River and Propst (1980) reported that the Johnny darter was present in the Illinois River west of Walden. As was explained under Section 779-20 the Johnny darter has been placed on the Colorado "threatened" list (Colorado Division of Wildlife 1978:18-20). 780-51 as
