West Elk Mine . These structures were designed per Exhibit 44. Runoff is released from the sedimentation ponds only after sufficient settlement of suspended solids and satisfaction of the effluent standards has been achieved. Disturbance of the adjacent areas was held to a minimum. The NPDES permits were secured prior to discharging. See Exhibit 7 to this Mining and Reclamation Plan. Construction practices are geared to minimize erosion in all disturbed areas (Exhibit 43). During construction of the ST-4 crushed coal stack-tube and storage area, drainage in the area was diverted into the enlarged MB-3 pond so that the former ponds MB-2 and MB-6 could be dried in preparation for the construction of pond MB-2R and the coal storage azea. Best Management Practices (BMP) were utilized during road construction associated with the Sylvester Gulch Facilities Area (PR07). BMPs were also utilized as the substation was constructed. Prior to the construction of the shafts site benches, aclear-water diversion ditch, designed to handle the peak flow from a 100-yeaz, 24-hour stone event, was constructed. In addition, prior to removing vegetation and stripping topsoil at the shafts site benches, sediment pond SG-1 was constructed. The shafts site will naturally drain to the sediment pond, so life-of- mine sediment ditches may not be constructed immediately, but will be established as the site is developed. Sediment contributions from drill sites constructed by MCC within the permit area will be minimized by clearing the smallest area possible, containing drilling water and cuttings in an appropriately-sized pit and reclaiming the site promptly upon completion. Reclamation would . include grading the site, redistributing topsoil, scattering vegetative slash, seeding, and mulching, if necessary. C~ 2.05-35 Revised June 2005 PR10; Rev. January 2006; Rev.
