• <br />• <br />• <br />The first 20 acre segment will be cleared of vegetation, dewatering trenches dug, and <br />stripped of topsoil and overburden during the winter months. Mining of the sand and <br />gravel will commence in the early spring of that first year and continue through year. <br />The sand and gravel will first be run through a primary screen to separate out fine sand <br />and clay. Approximately 50% of the mined material will be rejected by the screen. This <br />reject will be moved by a loader to the excavated area to become the bottom ten to 13 feet <br />of the backfill. <br />At the end of the first mining season, the second mining segment will be cleared of <br />vegetation. The topsoil and overburden will be stripped and deposited in its same layers <br />on top of the reject material of the first mining segment. The final backfill elevation will <br />be two feet above the average groundwater table. The area will be grass seeded in early <br />spring. <br />The mining of the second segment will progress as the first segment. When done, the <br />second segment is partially backfilled with reject material and is ready to accept the <br />topsoil and overburden from the third segment. <br />The topsoil and overburden for the third mining segment comes from the stockpiled <br />topsoil and overburden from the first mining segment. This last segment will be grass <br />seeded in the next spring following the mining. <br />(f) The final grading, seeding, fertilization, revegetation, and topsoiling have been <br />previously described in this section. <br />
