MINING PLAN <br /> This will rebuild a dry zone between the moist sand and the surface to help insure that ground water <br /> is not exposed. Although this soil layer may, in time, become moist that will only aid in the growth <br /> of the desired final vegetation. <br /> The final result of this approach to the mining will produce a rather gentle west facing slope <br /> that starts at the eastern end of the area mined (roughly 100 feet east of the current upper water zone <br /> extraction wells) and extends westward to meet the nearly flat bottom of the existing pit in the <br /> vicinity of the current permit boundary. It is estimated that at least 80% of the sand to be removed <br /> from the Little Johnson area will be contained in the land between the current mining limit (west of <br /> the current permit boundary) and the upper zone extraction wells.: <br /> Finally, it is important to recognize that the LJR groundwater extraction wells, their <br /> associated underground power line and underground water pipeline to the treatment plant will all b <br /> removed as a result of mining. This is fully acceptable to the remediation program as evidenced in <br /> documents elsewhere in this amendment. The Bradley Road groundwater extraction system (wells, <br /> power, and pipelines) will not be affected by this mining as they are all located well away from the <br /> mining area. <br /> NORTH END OF LITTLE JOHNSON AREA: Mining the north end of the Little Johnson area <br /> must be done with considerable care to avoid affecting the ditch corridor, IF THE DTICH HAS NOT <br /> BEEN RELOCATED BY THIS TIME. <br /> final slope.
