III IIIIIIIIIIIII III <br />999 <br />• <br />S~ INTRODUCTION <br />Energy Fuels Coal Incorporated (EFCI) utilizes an extensive drainage and <br />sediment control plan consisting of sedimentation ponds, clean water <br />diversions, sediment and refuse collection ditches, catchment basins and <br />culverts to control surface runoff within the Southfield mine and loadout <br />permit areas and limit contributions of suspended solids to receiving <br />drainages. Presently, three (3) sedimentation ponds and two (2) water- <br />use ponds exist within the mine area, and two (2) sedimentation ponds <br />exist at the coal loadout area. Specifically, the existing ponds are as <br />follows: <br />Doc Date:12/11/2001 <br />o Mine Area Ponds <br />- Sedimentation Pond No. 1 <br />- Water Treatment and Recycle Pond No. 2 <br />- freshwater Pond No. 3 <br />• - Sedimentation Pond No. 4 <br />- Sedimentation Pond No. 5 <br />o Loadout Area Ponds <br />- Sedimentation Pond L1 <br />- Sedimentation Pond L2 <br />Two (2) clean water diversions currently exist within the Southfield mine <br />area and serve to divert undisturbed runoff around the mine area to <br />natural drainages. The diversions are as follows: <br />o Magpie Creek Diversion <br />o Permanent Diversion No. 1 <br />Magpie Creek Diversion presently functions as a temporary structure and <br />upon final reclamation it will be upgraded to a permanent structure. <br />Permanent Diversion No. 1 is designed and presently functions as a <br />• permanent structure. Designs for both configurations are included. <br />A number of sediment collection ditches exist within the mine area and <br />loadout area which route surface runoff from the disturbed areas to the <br />I <br />
