TAB 13 <br />FACILITIES <br />Introduction <br />This chapter contains a description of the proposed structures to be used in connection <br />with or to facilitate the surface coal mining and reclamation activities at the Yoast Xine <br />area described in Che Coal Recovery and Protection Plan, Tab 12. <br />Sediment and 4ater Control Facilities Plan <br />Peabody utilizes various types of structures to control the runoff from disturbed areas <br />within the permit boundaries at [he Yoas[ Mine. In addition, surface mining activities <br />will be planned and conducted to minimize disturbance of the prevailing hydrologic balance <br />in both the mine plan and adjacent areas in order to prevent long-term adverse changes in <br />the hydrologic balance. <br />• i <br />i <br />l <br />i <br /> Sediment on <br />on of m <br />ning and rec <br />amat <br />control measures rill include proper utilizat <br /> methods and sediment control practices singly or in combination. Sediment control methods <br /> may incl ude, but not be limited to the follori ng: <br /> 1. Disturbing the smallest practicable area at any one time during the mining end <br /> construction operation; <br /> 2. Stabilizing graded material to promote a reduction in the rate and volume of <br /> runoff; <br /> 3. Retaining sediment within disturbed areas; <br /> 4. Diverting runoff grey from disturbed areas including stockpiles, backslopes, and <br /> materiel storage; <br /> 5. Diverting runoff through disturbed areas using stabilized earth channels, <br /> culverts or pipes so as to prevent, to the extent possible, additional <br /> contributions of sediment to st reamf low or to runoff outside the permit area; <br /> 6. Using stray dikes, silt fences, smell V-ditches, riprap, mulches, check dams, <br /> vegetative sediment filters, temporary cover crops, sediment traps, and other <br /> measures that rill reduce overland floc velocity, reduce runoff volume, or trap <br /> sediment; <br />1 <br />
