RECLANATiON PLAN <br />the soil to maximum extent. If done in the winter months a great deal of <br />. regrowth from the soil can be achieved in the revegetation process. Some of <br />that growth will be weeds, but a significant percentage will be the native <br />vegetation. Stockpiling of soil will be minimized to reduce cost and help <br />preserve whatever quality there is in the soil. Stockpiling has been shown <br />many times to degrade the biological properties of the soil, although it has <br />little effect on the nutritional quality of the soil derived from the <br />mineralized components. Ltifortunately, it is often the biological properties <br />that are essential to excellent growth. <br />After the gravel is removed to the shale layer, processing fines will be <br />replaced on the graded Land. The depth of these fines will be dependent upon <br />the depth of soil that will be replaced. Because a total depth (processing <br />fines plus soil) will be a minimum of 10 to 12 inches but less than 20 to 24 <br />inches, processing fines will be replaced to a minimum depth of 6 inches. <br />I-bwever, it should be recognized that the depth of fines that can be replaced <br />is dependent upon the amount of waste produced in the processing. If past <br />experience holds true, and there is little reason to think it should not, then <br />having a volume of processing waste such that 6 inches can 6e replaced should <br />not be a problem. If more is available it will be used, but the minimum of 6 <br />inches will be observed. <br />C>nce this material is laid down ai the shale, the soil will be placed on <br />tap of it. If the Csscajo soil is the one being placed then the depth will be <br />a minimum of 3 to 5 inches of soil. If the soil is of the more loamy types <br />(e.g. Stoneham loam) then the minimum depth will be 6 to 8 inches. Mixtures <br />and blends of the gravelly and loamy soils will be a minimum of 4 to 6 inches. <br />The spreading of the Czscajo soil will be done on very nearly a 1:1 <br />ratio. That is, soil of this type stripped from an acre will be placed on <br />about an acre. On the other hand, the better loam soils will be spread at <br />about a 1:1.25 ratio; an acre of stripped soil will be spread on about 1.25 <br />acres of land to be reclaimed. <br />This structuring of the soil (fines on the shale and soil on the fines) <br />has many advantages when attempting to revegetate land in acid climates like <br />this one. Fbwever, it only seems to work when the base material is fairly <br />impermeable like shale. If the base material is gravelly to a depth of more <br />Page 15 <br />
