Exhibit D CMLRB 112 Permit Application <br />Agile Stone systems. Inc. <br />• Each gravel area will be mined above the water table. The water table level in the <br />vicinity of the Gravel Baz Aggregate Pits is about 40' to 57' from the surface around <br />5,743' to 5,760'. The water table depth was measured from monitoring wells drilled at <br />various locations between the proposed gravel pit sites and the southem border of the <br />affected land boundaries by Azurite, Inc. (12/97) and a local contract well driller. See <br />Exhibit G -Water Information. Two of the test wells shown on the Mining Plan Map <br />were meant to function as monitoring holes but were dry holes with no water table level. <br />A 4.0 acre temporary topsoil stockpile will be constructed across the plant azea in an east <br />west direction between the railroad loop tracks. The topsoil stockpile will contain the <br />topsoil to vegetate the permanent berms constructed south of the gravel azeas and all <br />mined areas for final reclamation. The temporary topsoil stockpile will be graded to a <br />2.0:1 to 2.5:1 slope and vegetated with native grasses, forbes and shrubs discussed in <br />Exhibit E. South facing slopes will be less steep than the north, east or west facing slopes <br />to retain more moisture for plant growth. The height and base of the berm will undulate <br />varying the height and width to make the berm blend into the surrounding topography. <br />Permanent visual and noise reduction berms will also be built to minimize impacts to <br />neighboring lands south of the Arkansas River. The permanent berms, 8 acres, along the <br />southem margin of the permit boundary will only contain breaks to allow rail access. <br />The berms will undulate along the crest 20'-30' high, 70'-150' wide at their base with a <br />2:5 to 3:1 graded slope to promote a more natural appeazance. The berms will be <br />• constructed of finer sized products from the plant. The surface of finished berms will be <br />covered with 9" of topsoil recovered from the temporary topsoil stockpile. These berms <br />will also be vegetated with a diverse mix of native grasses, forbes, and shrubs. (Exhibit <br />E) South facing slopes will be less steep than the north, east or west facing slopes to <br />retain more moisture for plant growth. <br />The pits will be developed as product is required to meet market demand. Gravel Area <br />IB will be mined first followed by Gravel Area IA. After this 16.8 acres is mined, Gravel <br />Area Phase II and Phase III, comprising an additional 38 acres, will be mined. Gravel <br />Area IB may remain disturbed as a location to construct a permanent berm comprised of <br />long term plant material, such as fines, not sold. Some of the fines may be used to <br />reclaim areas on the quarry when mixed with topsoil. (Such consideration was requested <br />by 2 state agencies discussed later.) <br />2.3 Granite Quarry <br />The Granite Quarry, on the north side of Tallahassee Creek, will be developed in 3 <br />phases as a benched side hill cut. Phase I will involve 28.3 acres, excluding a stormwater <br />pond/berm) with 18.1 acres of mining with a quarry face from 5,780' to 5,950' and 10.2 <br />acres for a plant and stockpiling. Subsequent mining of Phases II and III at the quarry <br />include an additiona136 acres. The crest of the open pit at the end of mining would be at <br />about 6,150' with most of the pit floor at about 5,780'. Development of each of the 3 <br />phases could take up to 10 years each, although such time frames aze dependent upon <br />• product demand. <br />t0 <br />
