t <br /> Current water resource conditions and potential surface water and groundwater impacts are described in Exhibit G, <br /> Water Information. <br /> Groundwater—Specific Requirements <br /> Current water use on the proposed Tucson South Resource site consists of a permitted well field along the eastern <br /> portion of the site, adjacent to the South Platte River(owned and operated by the Todd Creek Metropolitan District) <br /> and limited depletions from existing wetlands on the site. The well permit for the gravel mining operation is also in <br /> place. Copies of the well permit and well completion report are included in Exhibit G,Water Information. <br /> This site is included in Aggregate Industries Substitute Water Supply Plan(SWSP)for the South Platte River. <br /> Specific information regarding water resources is included in Exhibit G. This plan will cover the depletions associated <br /> with the South mining cell(Phase 1)and water removed from the site with the material during mining. Once the site <br /> is reclaimed there will be no ongoing depletions associated with the property. The West and East cells will be <br /> reclaimed to lined water storage reservoirs and the South cell will be backfilled to the pre-mining surface grade. <br /> Tucson South Resource Groundwater Modeling Study on the hydrogeologic effects of Mining, prepared by Tetra <br /> Tech RMC dated August 2004 is attached herein for reference. A groundwater monitoring and mitigation plan was <br /> submitted to the Division as part of an adequacy response to Mr. Larry Oehler dated November 22, 2004(pages 17- <br /> 19). The plan was reviewed and approved by the Division as part of the original permit for the site. A copy of the <br /> approved plan is attached herein for reference in Exhibit G. Aggregate Industries obtained a well permit for the site <br /> in 2017 and filed the well 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 site. The operation will comply <br /> with State groundwater quality standards. Due to the absence of significant sources of potential pollutants, <br /> groundwater quality monitoring is not required in this operation. <br /> Buildings and Structures <br /> No buildings or structures associated with mining activities will be left in the proposed permit area following <br /> reclamation. <br /> Signs and Markers <br /> Permit notification signs will be placed and maintained at the entrance to the operation. The permit boundary will be <br /> identified where it is not already identified by fences or suitable markers. All signs and markers will be removed upon <br /> permit release. <br /> Aggregate Industries Tucson South Resource <br /> Permit#M-2004-044112 Permit Amendment <br /> Page E-8 <br />
