' EXHIBIT D S^3 MINING PLAN 1 Removal of the overburden shall start in the eastern portions of the gross area to be mined, such overburden to be stockpiled in the lower elevations of the project to catch any materials which might be carried offsite by water. Materials shall be mined from the lower elevations working upgradient in four acre sections to completion. The mined materials shall be transported on ' site to a screening and crushing facility located near the entry road access from Elbert County Road 25-41. As each four acre area is mined out and final grades are established, overburden in compliance with the Soil Conservation Service specifications will be moved from the newly opened four acre area to the mined out area. Additional topsoil will be trucked to the four acre closure area as required and basin terraces shall be installed to prevent erosion and protect ' the newly opened mining areas from invasion by eroded fines. Mining of materials and on-site transportation of materials shall be by wheeled scrapers and end loaders. The above activities are ' classified as major disturbances. There will be an access road to the mining site from Elbert County Road 25-41 which will involve a moderate disturbance in an area of 27,633 square feet. There will not at any time be an area of major disturbance ' which is in excess of twenty-percent of the total site. /' In addition to the wheeled scrapers and loaders mentioned ' above, the equipment on the site will include crushing and screening equipment and scales. The nature of the gravel, sand and rock which is to be mined ' is shown in the Chen & Associates report attached hereto and which is requested to be confidential information. The geologic structure underlying the deposit to be mined is typical Dawson Arkose. The nature, depth and thickness of the overburden and the deposit to be removed is shown on the drawing by Dale H. Hamilton dated 4-22-85 and other attachments to this exhibit.
