Exhibit E CIIILRB 112 Permit Application Agile Stone Systems. Inc. • 2.2 Topsoil Stockpile Stabilization Most of the topsoil stockpile is expected to remain in place for more than 1 growing season. Therefore, the stockpile will be stabilized upon completion by planting the Soil Stockpile Stabilization Mixture (Table 1) during the first available growing season. The surface of the stockpiles will be left in a moderately roughened condition sufficient to retazd erosion during construction. When construction is complete, composite soil samples will be taken from 0"-12" and 12"-24" beneath the surface. The samples will be sent to a laboratory for fertility analysis. Based on the laboratory analyses and fertilizer recommendations, fertilizer will be evenly broadcast over the stockpile at recommended rates and the seedbed roughened to incorporate the fertilizer into the seedbed. Seed, at the specified rates, will then be broadcast over the seedbed. The seedbed will be lightly roughened to cover the seed. The slopes will be mulched using straw at a rate of 4,000 lbs/acre or a wood fiber hydromulch at a rate of 2,000 to 3,000 Ibs/acre. Applied straw mulch will be anchored using a tackifier or crimping. The hydromulch will be applied with a tackifier to provide for mulch anchoring. After 2 or more vegetation seasons, the need for any type of netting to stabilize the mulch will be considered. Either drill or broadcast seeding techniques may be employed to maximize [he potential for stabilization.

Current grading plans include development of apost-mining topography graded to about 2.5:1 to 3:1. The gravel bar will be self contained due to the buffer remaining in place around all prior mining and plant areas. The gravel permeability as demonstrated by field percolation tests demonstrate that rain water will be absorbed by the gravel rapidly and not collect on the surface. After Gravel Area IA is mined, its north and east slopes will be graded to a 2.5:1 to 3.0:1 final slope and, along with the pit floor, have 9" of topsoil placed on it and be seeded, . fertilized and mulched. The west wall of the Gravel Area IA will not be reclaimed as it 5
