<br /> Over most of the area, the plant growth medium will be <br />• derived from the limestone produced in the mining process. The bedrock <br />which remains after mining has a rough surface and the finer material <br />should bind well to the substrate, tdo slippage of such materials has <br />occurred at any locations on the other quarries. The coarse, highly <br />permeable nature of the material does not lend itself to sustaining <br />the large amounts of water necessary to produce instability. The <br />erosion control terraces and ditches will be constructed shortly after <br />deposion of the material and therefore little erosional loss would be <br />expected. even in severe thunderstorms. <br />The plant growth medium will be produced by the following <br />procedure. In mining the limestone certain amounts of limestone simply <br />do not get picked up and remain as gravel, cobble, and a few boulder <br />• sized rocks mixed with ground rock. Other materials become crushed <br />into a fine material because of equipment running back and forth over <br />it. The fines produced by the equipment only extend to a depth of <br />about 6 inches. To crush the material below that level a two or three- <br />tined ripper would be mounted on the back of the cat and this would rip <br />through the rock below that 6 inch depth, pulling it to the surface <br />where it can be crushed by the cat. In this way at least 12 inches <br />of material would be produced. and in some places would probably reach <br />18 to 2? inches depth. <br />In places where the limestone is very completely removed and/or <br />is too hard completely to crush with the equipment the fines produced <br />in the processing operation would be hauled and deposited to make up <br />the difference. At any rate a dept}i of not less than 12 inches would <br />• be achieved and in most areas the medium may well exceed this minimum. <br />P-E-8 <br />
