expose groundwater and will not store stormwater for more than 72 hours. After reclamation, <br /> stormwater encountered in the mining area will be routed to the reclaimed pits and continue to <br /> infiltrate or evaporate. <br /> The two principal ways that the gravel pit could affect the water quality of the area downstream <br /> are a)through poor sediment control within the site causing increased sedimentation <br /> downstream, and b) by fuel leakage from a ruptured tank. Water that is encountered in the pit <br /> will not be released from the site. The only water that will be found within the disturbed area is <br /> stormwater runoff and water hauled to the mining area and used in processing and for dust <br /> control. All water from the disturbed area will drain to the bermed active pit and cannot leave the <br /> site. Fuel leakage will be prevented by the use of a 500 gallon double-walled diesel fuel tank on <br /> site. The double wall will serve as secondary containment. Adherence to strict SPCC Plan <br /> procedures for spill prevention and control will also prevent fuel leakage from the site. <br /> According to searches on the Division of Water Resources database, the nearest wells are within <br /> the permit area. They are water wells to support the oil and gas drilling, and a residential well <br /> associated with the cabin located on the property. The mining will not encounter groundwater, <br /> and therefore will not affect these wells. <br /> Additionally, there will be no groundwater exposure as part of this operation, and therefore there <br /> is no dewatering. <br /> 2. Groundwater <br /> This operation is not expected to directly affect surface or groundwater systems. Historically no <br /> ground water has been discovered on this parcel of land. This area is generally high and dry. No <br /> groundwater will be exposed during mining. There are no permits contemplated or needed. <br /> On the map there is shown an intermittent stream on the east of the property. There are no known <br /> seeps, springs, or reservoirs on the affected lands or adjacent lands. There are no known aquifers <br /> to be identified. This area is a terrace gravel deposit and no aquifers are known. There will be no <br /> dewatering operation or runoff from disturbed areas. A two-foot tall earthen berm will be placed <br /> around the downhill areas of all disturbed areas to prevent runoff from the pit area.
