Rule 3.1.6 Water—General Statements <br /> 1)During and after active mining activities,the reclamation plan is designed to minimize impact to <br /> surface and underground hydraulic balance and water quality by directing and collecting all surface <br /> flows to sediment control structures for settling of potential sediment and percolation of water into <br /> local soils and adjacent Eight Mile Creek drainage. A Stormwater Management Plan and Stormwater <br /> Discharge Permit has been issued for this site for the past twenty years and has been in compliance with <br /> all rules governing stormwater management and discharge to Eight Mile Creek. No water wells, <br /> irrigation ditches,or other surface or groundwater consumptive systems are located on or operated <br /> within the permit area. No potential for injury to existing water rights regarding the permitted or <br /> neighboring areas have been identified. It is planned to leave the sediment control pond structure in <br /> place until mining and reclamation is completed to help minimize sedimentation loading into Eight Mile <br /> Creek drainage by allowing for surface water collection and slowing of flow velocities prior to <br /> percolation into underlying soils or discharge into Eight Mile Creek drainage systems. The sediment <br /> pond will be removed at the completion of reclamation activities. <br /> 2) Earth berms will be used to enhance water collection at the low side of the sediment control <br /> structures not to exceed five feet in height. <br /> 3) All surface areas within the affected area will either be planted to an approved grass mix or covered <br /> in gravel for use as stockpile or truck loading areas. All exposed areas will be graded to conform with <br /> the localized drainage plan. <br /> Statement of Impacts to Groundwater <br /> Due to no water wells drilled on the affected land and no intersect with groundwater systems from <br /> gravel extraction operations,there is no known potential for impacts to groundwater systems that might <br /> operate at some distance below the surface of the affected lands. Geologic conditions are favorable for <br /> limited percolation conditions,a clay rich shale unit of sizeable thickness underlying the gravel zone. <br /> 1F-*A,t,,& �-7 7. 3 <br />
