<br /> <br />starts. The topsoil previously stockpiled in Stage 4 will be <br />used to reclaim areas mined previously. <br />r <br /> <br />When mining is complete in Stage 5, only what is left of <br />Stages 2 and 6 will remain to be mined. <br />The mining operation will continue year-round on a demand <br />basis. When clay or sand is required by the brick plants, the <br />materiel will be removed from the stockpiles at the mine. As the <br />stockpiles are reduced, new stockpiles will be created with mined <br />materials. <br />The clays to be mined lie in almost vertical strata (.0 to 80 <br />degrees from horizontal) which are interbedded with sends. Lerge <br />volumes of sand in the clay will make the material unsuitable for <br />the manufacture of brick. The majority of the unsuitable sands <br />will be excavated and stockpiled or will be used to reclaim the <br />area mined previously. Approximately 40 percent of the pit -, <br />volume is expected to produce waste sands. <br />After topsoil and overburden are removed, the clay will be <br />mined and stockpiled. On-site equipment may include, but is not <br />limited to, dozers, scrapers, backhoes, front-end loaders, dump <br />trucks and a water trailer. <br />The main source of water in the mining areas is expected to <br />come from minor runoffs. In the pits being mined now it has been <br />noted that water from runoff generally percolates through the <br />sand leaving the pits fairly dry. Runoff through Stages 1 and 3 <br />will be minor and drainage will present no problem. Stages 2, 4 <br />and 5 may have slightly greater drainage courses. During mining, <br />these courses will be diverted as needed to isolate the mined <br />12 <br />
