6.4.7 Exhibit G <br /> Water Information <br /> 1. This operation is not expected to directly affect surface water or ground water systems. <br /> The tributary aquifer for Arkansas River is approximately 40 to 50 feet below the ground <br /> elevation. This fact is evidenced by the lack of springs coming out of the bluff along Eight <br /> Mile Creek and by the Arkansas River. During the life of the mine, the ground water- <br /> table will not be encountered. Because of the distance of the wells, called out in Exhibit <br /> C.1, from the operation and the depth of the ground water table, none of the wells will <br /> be affected by the mining operation. Surface water runoff from the mined areas will <br /> flow toward the center of the current mined area. Material in that area will allow the <br /> water to percolate within 72 hours. If erosion gullies begin to form, the operator will <br /> install straw bales or boulders in the gullies to act as check dams and to control <br /> sediment. <br /> 2. Please see Exhibit C.1. <br /> 3. Water use during the Penrose Pit operation will require eight-acre feet of water for dust <br /> suppression annually. The applicant will use onsite water for this purpose. The concrete <br /> aggregate washing plant will use recycled water and occasional replenishment water <br /> will amount to four-acre feet per year. Please see attached lease for water with the <br /> Arkansas Groundwater Users Association (AGUA). The raw water for dust suppression <br /> and washing will be diverted from Eight Mile Creek. This water will be replaced by <br /> leasing shares from a nearby upstream ditch on the Arkansas River. Backup raw water <br /> requirements will be supplied by bulk water suppliers in either Penrose or Florence. <br /> Stormwater Permit COR340599 is currently active for this site. Bottled drinking water <br /> will be delivered to the site for the workers. <br />
