<br />Cripple Creek & Victor Gold Mining Company Exhibit G Cresson Project Amendment 13 1 <br />1 INTRODUCTION <br />As discussed in Exhibit D and under this amendment, the Schist Island mine area and Squaw Gulch Overburden Storage Area (SGOSA) will be modified to accommodate construction of the Phase 3 of the Valley Leach Facility 2 (VLF2). These modifications are not anticipated to significantly change the impacts to surface or groundwater systems that are contemplated by previous permit amendments. This exhibit has been updated, where necessary, to accommodate VLF2 Phase 3 modifications. <br />The following Exhibit G provides water information for the Cresson project including: <br />1. Location of water courses, wells, springs, and other features on the affected lands and adjacent lands that may be impacted by Amendment 13 activities (See Figures G-1 and G-2) and the programs in pace to monitor and protect surface and groundwater from current and future operations; <br />2. An estimate of the water requirements including flow rates and annual volumes for the mining and reclamation phases of the project; <br />3. The projected amount from each of the water supply sources that will supply water to the operation and reclamation; and <br />4. Discussion of the state of Colorado Discharge Permit System permits in place for the site. <br /> <br />Note that baseline surface water and groundwater data have been provided in prior submittals. Quarterly data are provided to the Division on Reclamation Mining and Safety (DRMS) on a regular basis and the data from the last 5 quarters are provided in Appendix 6 of this Amendment 13 permit. <br />Cripple Creek and Victor Gold Mining Company (CC&V) maintains a series of enhanced management ponds (EMPs) to control surface runoff from active operations and actively disturbed areas to protect surface water quality. CC&V also maintains three discharge permits to ensure water discharged off site satisfies water quality standards and maintains a current hydrogeologic model that demonstrates deep-diatreme groundwater is protected through the neutralizing capacity from carbonate rocks at depth. Lastly, CC&V maintains a monitoring program to monitor key components of the operation to protect surface water and groundwater systems. Various plans have been developed by CC&V to address the management of surface water and groundwater systems. <br />The following sections describe the different surface water drainages affected by the operation, provides an overview of the hydrogeological model used to protect groundwater, and describes
