Response: This operation will not impact the ground water. The proposed operation is a <br />dry mining operation with Post Mining Land Use as rangeland. The disturbed areas will <br />be reclaimed as rangeland. The operation will not have any impact to the ground water <br />flow system. The depth to ground water varies from approximately 12 feet to <br />approximately 30 feet deep with in the proposed permit boundary. The ground water is <br />tributary to the Arkansas River and generally flows from west to east through the <br />alluvium. <br />(2) If the operation is expected to directly affect surface or groundwater systems, the <br />Operator /Applicant shall: <br />(a) Locate on the map (in Exhibit C) tributary water courses, wells, springs, stock water <br />ponds, reservoirs, and ditches on the affected land and on adjacent lands where such <br />structures may be affected by the proposed mining operations; <br />Response: This operation will not directly affect the surface or groundwater systems, the <br />surface water courses are shown on Exhibit C Pre - Mining Plan Maps Sheet 1 through 5. <br />(b) Identify all known aquifers: <br />Response: The only known aquifer is the alluvial aquifer into which the Operation will <br />mine. No aquifers below the hard claystone bedrock will be affected by the proposed <br />mining or reclamation operations. <br />(c) Submit a brief statement or plan showing how water from de- watering operations or <br />from runoff from disturbed areas, piled material and operating surfaces will be managed <br />to protect against pollution of either surface or groundwater (and, where applicable, <br />control pollution in a manner that is consistent with water quality discharge permits), <br />both during and after the operation. <br />Response: A application for stormwater discharge associated with sand & gravel mining <br />and processing permit will be required from the Water Quality Control Division, <br />Colorado Department of Public Health and the Environment. The Operator will develop <br />and implement a site - specific Stormwater Management Plan and a Spill Prevention, <br />Control and Countermeasure Plan (SPCC) prior to beginning mining operations. The <br />Operator will obtain a stormwater discharge associated with sand & gravel mining and <br />processing permit from the Water Quality Control Division, Colorado Department of <br />Public Health and the Environment. <br />(3) The Operator /Applicant shall provide an estimate of the project water requirements. <br />Including flow rates and annual volumes for the development, mining and reclamation phases of <br />the project. <br />Response: Project water requirements for mining and reclamation will be water <br />needed for dust control. The estimated annual amount needed is 0.50 acre -feet per <br />year. Water used for dust control shall be purchased from a legal source such as the <br />Pueblo Water Works or other authorized vendors. <br />(4) The Operator /Applicant shall indicate the projected amount from each of the sources of water <br />to supply the project water requirements for the mining operation and reclamation. <br />
