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 <br /> material is sand. There may be a connection to the underlying ground water system <br /> however, the depth to ground water is not known. If ground water is encountered,the area <br /> will be backfilled with two (2)of pit run or other suitable material above the potential <br /> ground water elevation. Care will be taken to stay at least two (2) feet above any known or <br /> discovered ground water. <br /> In addition,this is a sand and gravel operation and does not expose or produce any toxic or <br /> acid producing materials. No fuel tanks will be on-site or other toxic or acid producing <br /> materials. If fuel or oil spills occur on site in reportable quantities, they will be cleaned up. <br /> (2)(a) If the operation is expected to directly affect surface or ground water <br /> systems,then locate water structures facilities, etc. on Exhibit"C": <br /> No affects to ground or surface water have occurred with the existing 110 Operation and <br /> none are expected for the conversion to a 112 permit. <br /> (b) Identify all known aquifers: <br /> No aquifers are known. Based on a search of the Division of Water resources website, no <br /> borings or wells exist in the vicinity of the operation to provide information on aquifers. <br /> (c) Provide a plan showing how water from de-watering operations or from <br /> runoff from disturbed areas, stockpiles, and operating surfaces will be managed to <br /> protect against pollution of surface and ground water, both during and after <br /> operations: <br /> There are no dewatering operations associated with this operation. Runoff from <br /> stockpiles will be controlled through seeding topsoil stockpiles. Straw bales or other <br /> suitable erosion control measure will be placed along the toe of topsoil stockpiles to <br /> control sediment until grass is established on the stockpile. (Erosion control materials <br /> may have to be removed during soil placement into stockpiles and when the stockpile is <br /> being seeded.) Once the grasses become established, no significant erosion should occur <br /> from the topsoil stockpiles and straw bales or other erosion control materials will not be <br /> needed. <br /> The 1.5% grade of the pit floor and its sandy nature will retard any runoff. Essentially, <br /> runoff will flow gradually toward the existing ephemeral drainageway which runs <br /> 40 <br />
