EXHIBIT "G" <br /> 6.4.7 Water Information: <br /> (1) Impact to ground water: <br /> We do not anticipate significant impacts to groundwater. The immediately underlying material is <br /> sand. There may be a connection to the underlying ground water system however,the depth to <br /> ground water is not known. If ground water is encountered,the area will be backfilled with two <br /> (2) feet of pit run or other suitable material above the potential ground water elevation. Care will <br /> be taken to stay at least two (2) feet above any known or discovered ground water. <br /> In addition,this is a sand and gravel operation and does not expose or produce any toxic or acid <br /> producing materials. No fuel storage or transfer tanks will be on-site or other toxic or acid <br /> producing materials. If fuel or oil spills occur on site in reportable quantities,they will be cleaned <br /> up and the waste disposed in an approved facility. <br /> (2)(a) If the operation is expected to directly affect surface or ground water systems,then <br /> locate water structures facilities, etc. on Exhibit"C": <br /> No affects to ground or surface water have occurred with the existing 110 Operation and none are <br /> expected for the conversion to a 112 permit. <br /> (b) Identify all known aquifers: <br /> The only aquifer in the area is the Big Sandy, a shallow alluvium aquifer. The existence of the <br /> aquifer was overlooked during the preparation of the application. With this revision the error <br /> is corrected <br /> (c) Provide a plan showing how water from de-watering operations or from runoff <br /> from disturbed areas,stockpiles, and operating surfaces will be managed to protect <br /> against pollution of surface and ground water, both during and after operations: <br /> There are no dewatering operations associated with this operation. Runoff from stockpiles will <br /> be controlled through seeding topsoil stockpiles. Straw bales or other suitable erosion control <br /> measures will be placed along the toe of topsoil stockpiles to control sediment until grass is <br /> established on the stockpile. (Erosion control materials may have to be removed during soil <br /> placement into stockpiles and when the stockpile is being seeded.) Once the grasses become <br /> established,no significant erosion should occur from the topsoil stockpiles and straw bales or <br /> other erosion control materials will not be needed. <br /> The 1.5% grade of the pit floor and its sandy nature will retard runoff. Essentially,runoff will <br /> flow gradually toward the existing ephemeral drainageways which run adjacent to the operation. <br /> 41 <br />
