RECEIVED <br /> Rifle Gravel Pit#1 IJUL 19 2023 July 2023 <br /> Colorado Division of Reclamation, <br /> 8.0 Exhibit G — Water Information Mining and Saftey <br /> Figure 17, Exhibit G depicts the rivers, creeks, water courses, and ditches on the site and <br /> adjacent lands. <br /> Use of wet mining techniques in the highly permeable aggregate deposit underlying the Rifle <br /> Pit will minimize affects to local groundwater and surface water. In essence, the shallow <br /> groundwater currently underlying the site will be exposed as the surface of the excavated <br /> pond, but the volume and direction of flows will not be altered. <br /> 8.1.1.1 Water—General Requirements <br /> Scott will minimize disturbances, to the extent practicable, to the prevailing hydrologic <br /> balance of the Affected Lands and of the surrounding area and to the quantity or quality of <br /> water in surface and groundwater systems both during and after the mining operation and <br /> during reclamation by: <br /> • Complying with applicable Colorado water laws and regulations governing injury to <br /> existing water rights. <br /> • Compliance with applicable federal and Colorado water quality laws and regulations, <br /> including statewide water quality standards and site-specific classifications and <br /> standards adopted by the Water Quality Control Commission. <br /> • Compliance with applicable federal and Colorado dredge and fill requirements. <br /> • Removing temporary or large siltation structures from drainage ways after disturbed <br /> areas are revegetated and stabilized, as required by the Reclamation Plan. <br /> • No earth dams will be constructed to impound water. <br /> • All surface areas of the Affected Lands, including spoils piles stockpiled for more <br /> than 180 days, will be stabilized and protected so as to effectively control erosion. <br /> • Scott has installed piezometers to monitor the groundwater levels on the parcel and <br /> can provide that data upon request. Note the one on the east side of the property will <br /> be removed during mining. <br /> 8.1.1.2 Groundwater—Specific Requirements <br /> • Scott will not be discharging to groundwater nor surface waters. <br /> • Scott will not have an in-situ leach mining operation. <br /> • Scott has installed piezometers to monitor the groundwater levels on the parcel and <br /> can provide that data upon request. <br /> See Section 8 and Figure 17, Exhibit G for more information regarding water. <br /> 47 <br />
