Section 780.16 (a) Continued. fisheries population, the only anticipated impact on the aquatic communities at the Kerr Mine Area will be an increase in sediment deposition between disturbed areas and sedimentation structures. However, ae shown by recent studies conducted along the Illinois and Canadian Rivers (1976), Britton (1979), Schroeder, et al. (1979) and Propat (1980), there does not appear to be any correla- tion between increased sediment deposition related to coal mining and decreases in aquatic biota diversity. Promo osAd' Plan fb"r" Miti:gatioci "df AdvAts@' Impact's' t"o" WtTdlffe Reri Mine Area Impacts on the wildlife resources on the Kerr Mine Area will be minimized by designing and implementing the operations and subse- quent reclamation plan to avoid, where practicable, disturbances to wildlife habitat. For example, blasting will not be done during early morning or late evening hours when wildlife is most active. Similarly, off-road vehicle use on the permit area will be kept to a minimum. Furthermore, appropriate positioning of fences will ex- clude wildlife from active mining areas. Where disturbance cannot be avoided, impacts to wildlife will be minimized not only through proper positioning of haulroads, over- burden stockpiles, topsoil stockpiles, sedimentation ponds, and other mine support facilities, but also through implementation of effective reclamation. In addition, throughout the mining opera- tion Kerr Coal will attempt to keep the noise generated by mining activities to a minimum by operation of the heavy equipment within the pit as much as possible. Finally, as each stage of mining is completed, Kerr Coal will undertake a thorough reclamation program designed to return the affected land to its premining condition. The approximate original contour of all disturbed areas will be re- stored according to the techniques described in Section 816.102. Restoration of the approximate original contour will re-establish 780-45
