Groundwater-Specific Requirements <br /> Current water use on the proposed Tucson South Resource site consists of a permitted <br /> well field along the eastern portion of the site, adjacent to the South Platte River (owned <br /> and operated by the Todd Creek Metropolitan District) and limited depletions from <br /> existing, non-jurisdictional wetlands on the site. The well permit for the gravel mining <br /> operation is also in place. Copies of the well permit and well completion report are <br /> included in Exhibit G, Water Information. <br /> This site is included in Aggregate Industries Substitute Water Supply Plan (SWSP) for <br /> the South Platte River. Specific information regarding water resources is included in <br /> Exhibit G. This plan will cover the depletions associated with water removed from the <br /> site with the material during mining. Once the site is reclaimed there will be no ongoing <br /> depletions associated with the property. The West and East cells will be reclaimed to <br /> lined water storage reservoirs. Groundwater will not be exposed along the conveyor <br /> alignment. <br /> Tucson South Resource Groundwater Modeling Study on the hydrogeologic effects of <br /> Mining, prepared by Tetra Tech RMC dated August 2004 is attached herein for <br /> reference. A groundwater monitoring and mitigation plan was submitted to the Division <br /> as part of an adequacy response to Mr. Larry Oehler dated November 22, 2004 (pages <br /> 17-19). The plan was reviewed and approved by the Division as part of the original <br /> permit for the site. A copy of the approved plan is attached herein for reference in Exhibit <br /> G. Aggregate Industries obtained a well permit for the site in 2017 and filed the well <br /> completion report with the Colorado Division of Water Resources in 2018. A copy of the <br /> well permit and well completion report are also included in Exhibit G. <br /> The mining and reclamation operation will not affect groundwater quality on or off the <br /> site. The operation will comply with State groundwater quality standards. Due to the <br /> absence of significant sources of potential pollutants, groundwater quality monitoring is <br /> not required in this operation. <br /> Buildings and Structures <br /> No buildings or structures associated with mining activities will be left in the proposed <br /> permit area following reclamation. <br /> Signs and Markers <br /> Permit notification signs will be placed and maintained at the entrance to the operation. <br /> The permit boundary will be identified where it is not already identified by fences or <br /> suitable markers. All signs and markers will be removed upon permit release. <br /> Aggregate Industries—Tucson South Amendment—MLRB 112 Permit Application <br /> Exhibit E-9 <br />
