Exhibit E CMLRB 112 Permit Application <br />Agile Slone Systems. Inc. <br />• will be mined into Gravel Area Phase II. In this way Gravel Area IA will be reclaimed <br />concurrent with mining Gravel Area Phase II. A small haul road may run through Gravel <br />Area IA. Topsoil from Gravel Area Phase II will be used in reclaiming Gravel Area IA. <br />Any excess topsoil will be placed on the temporary topsoil stockpile. <br />Likewise, at the completion of Phase II mining, the north and south slopes of the Phase II <br />area will be graded to a 2.5:1 to 3.0:1 slope, have 9" of topsoil on top of it and the pit <br />floor and be seeded, fertilized and mulched. The west slope of the Phase II area will be <br />mined into the Phase III azea. After the Phase III azea is mined, the north, west and south <br />slopes will be graded to a 2.5:1 to 3.0:1 slope, receive 9" of top soil on top of the slopes <br />and the pit floor and be seeded, fertilized and mulched. South facing slopes will be less <br />steep than the north, east or west facing slopes to retain more moisture for plant growth. <br />Gravel Area IB will not be reclaimed until final reclamation. If it appears there is no <br />excess material from product production, it will be reclaimed as shown in the final <br />reclamation map. If it appears that there is excess material from product production, it <br />will be stored here. Sufficient topsoil has been preserved for either case. Whether <br />Gravel Area IB drops or rises in elevation, sufficient topsoil has been preserved, the azea <br />will be seeded, fertilized and mulched and the slopes will be essentially the same as <br />shown or flatter. During reclamation, any excess material in Gravel Area IB will be used <br />to flatten slopes around the gravel bar, plant area and used, if successful, in the admixture <br />for revegetation in the quarry azea. <br />• Granite Quarry <br />The granite quarry will have 19.04 to 33.11 acres in either concurrent or final reclamation <br />respectively while the sandstone quarry will have 1 to 3 acres for final reclamation. The <br />storm water berms and retention ponds will remain for long term erosion stability of the <br />reclaimed quarry areas. Due to the improved status of the land from the granite quarry <br />floor, the road from the quarry to the southeast part of the permit azea, parallel to the <br />berm, will remain for the long term likely use by the ranch. <br />Highwalls/Benches <br />The quarry benches will involve 15 to 22 acres. Several points along each highwall will <br />be blasted to create "talus slopes" impeding access to the benches, controlling key <br />erosional areas along and from the benches and blocking access to and along the benches. <br />The highest benches will have a bench 25 - 37.5' wide and will not be vegetated due to <br />access and limited bench width. The lower benches will vary in width from 25' to 50'. <br />Areas along the lower benches will be reclaimed and seeded, left barren or have an <br />artificial talus slope generated from blasting. The benches will have a 1-2% grade down <br />from the crest to the highwall toe to drain storm water runoff back into each bench and <br />along the bench drainage into intermittent talus slopes. The remaining final highwalls are <br />expected to be 50' high with a 0.25:1 slope. <br />The reclaimed benches will have 12" of topsoil and/or topsoil admixture placed on them. <br />• The extent of topsoil placement will depend upon the available topsoil. Any admixture <br />6 <br />
