Exhibit D- Mining Plan <br /> established concurrently with extraction and will conform to Rule 3.1.5(7), as <br /> detailed under Exhibit E—Reclamation Plan. <br /> Initially a 1600f foot extraction front will advance along its east-west orientation <br /> from the northern extraction limit toward the southern permit boundary. The <br /> advancing front will be comprised of side slopes of nearly 400 linear feet along <br /> each side of an 800 foot 1.25H:1 V advancing wall. Concurrent reclamation will <br /> trail this front by approximately 400 foot increments. This front is approximate for <br /> all active Tracts. As the basin floor and perimeter boundary is reached, final <br /> grading may commence once a minimum area of approximately four acres (or a <br /> distance of 400 linear feet square) is attained. Finished slopes will be established <br /> along the basin perimeter utilizing fill material taken from the basin bottom. If <br /> Tract B opens concurrently at some point in time with Tract A, as per Exhibit L — <br /> Warranty Costs, additional warranty may be applied to include the second <br /> advancing extraction front. <br /> Soils encountered during extraction will vary over the location in depth and extent. <br /> Actual soil variations, depths and descriptions, including potential volumes to be <br /> extracted, are detailed in Exhibit I & J: Soils and Vegetation Information, and are <br /> shown on Exhibit I & J: Soil and Vegetation Map. The soil volumes essential for <br /> reclamation of affected lands remaining above the anticipated static water level <br /> (4795'± elevation) of the completed basins will be salvaged and stockpiled from a <br /> portion of the upper six inches of the native soil profile (the `topsoil'). The <br /> remaining soils found within the solum or generated by plant processing activities, <br /> and in excess of that required for reclamation of affected lands, will be utilized for <br /> sale to help satisfy the infrastructure and development demands of the surrounding <br /> community. <br /> As indicated in Exhibit E — Reclamation Plan; of the 96.49± acres of potential <br /> extraction, the resulting basins will function as reservoirs with a water surface <br /> covering 89.37± acres. This leaves a balance of 7.12± acres (4.06± acres West <br /> Basin & 3.06± acres East Basin) of affected land within the extracted basins above <br /> the anticipated static water level. When combined with 34.00± acres of Mineral <br /> Reserve Areas used for support operations, a potential 41.12± acres may require <br /> recoiling and revegetation over the life of the operation. <br /> Initial resoiling and revegetation burdens are actually far less, since full build out <br /> takes up to 30-35 years to complete. Tract A (West Basin) at full build out has <br /> 4.30± acres of affected land within the extracted basin and above the anticipated <br /> Varra Companies, Inc.
