For Small Area Exemptions, samples will be obtained <br />of initial discharge if reasonably feasible, during a significant precipitation event to verify compliance <br />with applicable effluent limits. Sample analysis resulu will be included with the corresponding years <br />Annual Hydrologic Report. <br />Soil Materials <br />The initial mining disturbance within the area encompassed by the current permit boundary occurred <br />in 1902 and much of the present mine disturbance area was impacted prior to requirements for soil <br />salvage. Specifically, surface disturbance occurred and soil materials were not salvaged in the East <br />Yard; Ells Creek coal handling, support, and ancillary facilities; Beaz Creek; and Hubbard Creek areas <br />and for many of the existing haul, access, and light-use roads. These areas are shown and designated <br />on the General Facilities Map, (Map 2.05-M1). <br />For all surface disturbance subsequent to 1978, available soil materials which were operationally <br />feasible to salvage have been or will be recovered from new disturbance areas for use in reclaiming <br />both old and new disturbance areas. A surnmzry of soil stockpile and replacement volumes is <br />included in Exhibit 2.05-E5, Reclamation Details. Operational limits on soil salvage generally relate to <br />the rugged retrain of the area and include minimal soil depths, steep slopes, excessive rock content, <br />rocky outcrops, and other environmental factors. Where soil salvage is operationally feasible, soil <br />salvage and handling will involve the following general activities in compliance with applicable <br />provisions of Rule 4.06: <br />• Establish temporary drainage and sediment control to control runoff and sediment during <br />• soil removal operations. This may involve the use of ditches, berths, silt fences, straw bales, <br />or other temporary control measures. <br />• Conduct clearing operations to remove any large trees or shmbs (> 4-inch diameter) prior to <br />soil removal. These materials are placed in slash piles on the perimeter of the disturbance <br />areas that either remain as small trrarrutral habitat or are disposed of. Smaller vegetation is <br />removed during soil salvage and incorporated into the soil material as mulch and to maintain <br />anyviable plant propagules. <br />Salvage available soil materials. Soil salvage involves the use of, tracked doors, wheel <br />loaders, scrapers, and/or trucks to remove, load, and haul the soil materials. Target soil <br />salvage depths are identified by sampling soil removal areas prior to salvage in the limited <br />areas where soil depths are somewhat uniform. Generally, soil materials will be recovered to <br />a tnatdrnum depth of 4 feet. Actual soil salvage operations are guided by visual observation <br />with the objective of recovering all reasonably available and recoverable topsoil and subsoil <br />materials. Recognizing that heavy clay soils are not suitable as a revegetation medium, clayey <br />soils will only be recovered if there are sufficient volumes of suitable non-clay soils (loans <br />and sandysoils) for blending. <br />• Soil materials recovered from new disturbance areas are either drrect hauled to active <br />reclamation areas, if available, or to the designated soil material stockpiles shown on the <br />General Facihties Map, (Map 2.05-M1), for temporary storage and future reclamation use. <br />Soil removal volumes will be detemwred by surveying the soil stockpiles. Soil stockpiles are <br />located away from active[ ~o_pl1e__r``a``tions to the extent possible and are located and configured to <br />3nt~1W17P the f1C1fP_Qnal ~.LU x~- PSS15101~.
