r~ <br />Section 780.12(bj Continued. <br />Sedimentation Ponds <br />The existing sedimentation ponds at the Marr Mine and Kerr tipple are <br />shown and numbered on Map 28, Kerr Mine Existing Structures and Map <br />29, Kerr Tipple Area Existing Structures. All of these sedimentation <br />ponds were reconstructed in 1979 and 1980 to comply with the <br />performance standards of Subchapter K (Permanent Program Standards). <br />Sedimentation ponds within the proposed disturbed area which were <br />abandoned as a result of the new sedimentation and drainage control <br />plan have been removed and reclaimed in accordance with Section <br />780.18. <br />Kerr Coal's comprehensive sedimentation and drainage control plan for <br />the entire operation also involved the construction of new <br />sedimentation ponds and diversion ditches. All new sedimentation <br />ponds have been designed to comply with the requirements of <br />Subchapter K as described in Section 780.25. <br />The locations of all new or existing sedimentation ponds are shown on <br />Map 16a, Kerr Mine Area Surface Water Hydrology and Map 17a, Kerr <br />Tipple Area Hydrology. <br />Power Lines <br />\ Kerr coal utilizes only two powerlines, as shown on Map 28, Kerr Mine <br />Existing Structures and Map 29, Kerr Tipple Area Existing Structures. <br />One power line is a 14.4KV line which services the shop, office, and <br />warehouse facility. The other is a 14.4KV line which services the <br />tipple facilities. Electric power for both the mine and tipple is <br />obtained from Mountain Parks Electric. The power pole diagrams for <br />the two lines are shown on Figure 15, Existing Power Pole Diagram <br />(Mine) and Figure 16, Existing Power Pole Diagram (Tipple). Both <br />existing power lines were installed during 1974. Kerr Coat does not <br />plan to install any additional power lines. <br />89-22R Revised - January, 1991 <br />
