EYHIBIT D (Cont'd.) <br />1 <br />' will be used to resoil areas previously backfilled and graded <br />using overburden from earlier stages. No overburden from Stages <br />' 2-6 will be stockpiled. Overburden stockpiles from pre-law areas <br />and Stage 1 currently exist but will be removed and used as refill <br />' as mining in Stage 1 proceeds. <br />Two areas will be used for stockpiling soils. On P.fap <br />Exhibit D-1 these areas are designated Soil Stockpile 1 and Soil <br />' Stockpile 2. Stockpile 1 will be used as needed for soils from <br /> parts of Stages 1, 2, 3 and 4; and Stockpile 2 will serve parts <br />' of Stages 2, 3, 4, 5 and 6. <br /> There are approximately 1.41 acres of existing access roads. <br /> <br /> It is expected that when mining is complete on Stage 1, approxi- <br />' mately 0.41 acres will be reclaimed with the reclamation of the <br />pre-law area and Stage 1. Thus, only about 1 acre of access <br />' road will exist during most of the life of the mine. <br />Soils vary in thickness from about 8 inches to about 60 inches, <br />with the average maximum salvageable soil being about 18 inches. <br />' Overburden to be used for backfilling and final grading varies in <br />thickness from approximately 18 inches to 22 feet; the average <br />' thickness is approximately 10 Feet. <br />After the soil and overburden are stripped, the clay will <br />' be mined with a dozer. The dozer will stockpile amounts suffi- <br />' cient to meet current calls for the specification of this pit's <br />clay. Clay will be loaded on trucks by a front-end loader for <br />transport to the plant. As mining proceeds, the dozer will create <br />benches at various levels (see A1ap Exhibit D-1 east side slopes). <br />11 <br />
