• The "P" samples were taken from the top of the coal pad area. Each <br />sample was segregated into two one foot increments and then the <br />remainder of the horizon. The two one foot increments were <br />analyzed to determine if the material has been degraded by water <br />leaching down through the coal and into the soil. The results of <br />the laboratory analysis indicate the colluvial material immediately <br />below the coal pad has not been significantly degraded and all of <br />the soil samples are suitable plant growth media. <br />The quantity of suitable plant growth media was calculated based on <br />the depth of the test holes. The quantity information is presented <br />on the Present and Post Disturbance Cross Section Map, Map 13. A <br />total of 15,206 cubic yards of plant growth media was identified. <br />It is likely the entire bench is comprised of plant growth media. <br />The 15,206 cubic yards of plant growth media will provide an <br />average of 16.6 inches of subsoil for a total soil depth of 22 <br />inches (16.6'_ + 5.4"). <br />Prior to conducting reclamation operations, the location and extent <br />of the plant growth media will be verified. This action is <br />necessary to assure the plant growth media is placed on top of the <br />regraded area so it is located immediately below the topsoil layer. <br />• <br />• 2.05 - 8c <br />New 05-26-94 <br />
