RULE 2 - PERMITS <br />that have been successfully reclaimed and revegetated and, for which CDRMS has approved Phase I <br />and Phase II Bond Release. Pond 003 is the stormwater retention structure for the north facilities <br />area. Both of these ponds are permitted industrial stormwater discharge structures under the <br />existing Seneca II Mine CDPS permit — the two structures will be included in the PSCM CDPS <br />permit as effluent outfalls and sample compliance points. Map 2.05.3 M4, Drainage and Sediment <br />Control Plan, shows the location and flow relationships for all stormwater control features and <br />diversions. Additional information on stormwater conveyance structures is presented in Section <br />2.05.6 and in Exhibit 2.05.3 -E2, Drainage and Sediment Control Plan. <br />Soil Material Handling <br />Available soil or suitable plant growth materials will be salvaged prior to disturbance in the surface <br />facilities and other mine disturbance areas and stockpiled for use in reclaiming these areas. Given <br />the limited area available for mine surface facilities, all of the salvaged soil material will be placed <br />in the soil stockpile, located to the southwest of PECOCO Pond, as shown on the Mine Facilities <br />Map (South End) (Map 2.05.3 -MIA). The Soil Stockpile will contain approximately 140,000 <br />cubic yards, and is located and configured to minimize erosion potential and to prevent loss or <br />degradation of the soil resource. Soil stockpile signs will be placed and maintained on the soil <br />stockpile in compliance with the applicable requirements of Rules 4.02.4 and 4.02.7. The stockpile <br />will be stabilized with a quick establishing vegetative cover. Silt fence or wattles may be placed at <br />the toe of the stockpile slope to minimize sediment. <br />Where soil salvage is operationally feasible, soil salvage and handling will involve the following <br />general activities, in compliance with applicable 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, berms, silt fences, straw bales <br />or wattles, or other temporary control measures. <br />• Conduct clearing operations to remove any large shrubs prior to soil removal. These <br />materials will be placed in slash piles on the perimeter of the disturbance areas and disposed <br />of Smaller vegetation is removed during soil salvage and incorporated into the soil material <br />as organic matter. <br />• Salvage available soil materials. Soil or suitable plant growth material salvage will involve <br />the use of tracked dozers, wheel loaders, scrapers, and /or trucks to remove, load, and haul <br />the soil materials. Target soil salvage depths are identified in Section 2.04.9 Soils Resource <br />Information and Exhibit 2.04.9 -E1 Soils Information. Actual soil salvage operations are <br />guided by visual observation, with the objective of recovering all reasonably available and <br />recoverable soil, subsoil, and suitable plant growth materials. Recognizing that heavy clay <br />soils are not suitable as a revegetation medium, clayey soils will only be recovered if there <br />are sufficient volumes of suitable non -clay soils (loams and sandy soils) for blending or <br />meet the criteria in the above soils section and exhibit. <br />• Soil materials recovered from new disturbance areas will be hauled and placed in the Soil <br />Stockpile shown on the Mine Facilities Map, (Map 2.05.3 -MIA, Mine Facilities Map <br />(South End) for temporary storage and future reclamation use. Soil removal volumes will be <br />determined by surveying the soil stockpile. The soil stockpile area which will be seeded <br />TR- 01 -10. 2.05 -24 Revision 02/11 <br />
