EXHISTT E Soil will be respread over prepared subgrades of the pit inslopes, disturbed areas immediately bordering the pit slopes, and the overburden stockpiles remaining on site following the cessation of operations. Soil will be replaced to a uniform depth of approximately 2.0 feet (30,000 cubic yards) over pit inslope disturbances to provide a suitable growth medium depth. Approximately 1.0 foot of soil will be replaced over the disturbed area immediately bordering the pit slopes and the overburden stockpiles. A lesser replacement depth was considered acceptable for these disturbances since the sub-base materials of these facilities will be characterized primarily by subsoils. An application depth variance of plus or minus 0.33 foot will be considered acceptable given equipment limitations. Following replacement, the resoiled surface will be fine graded to remove surface undulations while leaving the overall surface in a roughened condition. All final grading will be completed along the contour, where safety conditions permit, to minimize erosion and maximize site stability. The graded surface will be chiseled or disked following 5na1 grading if the potential for subsequent erosion would compromise revegetation success. Ideally, soil will be applied on areas to be revegetated 30 to 45 days prior to seeding. Pit Insloves The pit inslopes will be graded, following material extraction, to the desired shape and form with slopes not exceeding 3H:1 V. The graded areas will be left in a roughened condition to decrease the potential for erosion and to eliminate any slippage plane between the subgrade and soil materials to be applied. Ripping will be completed, as necessary, to aid in achieving this condition. Soil will then be applied to a depth of 2.0 feet and the area rough-graded to meet the desired post-mining topography. Soil samples will be taken for laboratory analysis. With the receipt of fertilizer recommendations, the resoiled surface will be disked and fertilizer broadcast (excepting nitrogen) at rates specified as a result of soil tests. The seedbed will be disked to incorporate the fertilizer into the applied soil and to prepare the area for seeding. Following disking, the seed mixture shown in Table E-4: Grassland Planting Mixture will be drilled into the seedbed with the specified shrub seed broadcast over the seedbed concurrently. The planted area will then be mulched with straw at a rate of 2.0 tons per acre and the mulch anchored by crimping. Mulch anchoring will terminate from 3.0 to 5.0 feet upslope from the water line to address safety considerations. Drill seeding and mulch anchoring will take place along the contour to reduce the potential for erosion. The required amount of nitrogen fertilizer will be broadcast over the seeded area at the beginning of the second growing season. Overburden Stockpiles The surfaces of the stockpiles will be ripped, disked, or otherwise roughened to reduce the slippage plane between the overburden and the soil to be applied. Approximately 1.0 foot of soil will then be applied to the stockpile surface and the soil final graded to achieve the desired contours taking care to leave the surface in a roughed condition to retard erosion. Soil samples will be collected for analysis.
