• within a two-mile radius of the Cresson Project permit boundary. Drawing G-2 shows surface water filings and springs with a water right filed with the Office of the State Engineer within that same two-mile radius. Ground water monitoring information contained in Section 4.6.2 and Appendix 2 includes at least five successive calendar quarters of data for the existing wells. Ground water data have been summarized for approximately 15 monitoring wells in the Cresson Project area, excluding Grassy Valley. Another 16 wells have been installed and monitored in Grassy Valley and are also discussed in Section 4.6.2 and Appendix 2. As noted previously in Section 4.6.2, ground water is not developed for use in this area and is not anticipated to be developed for use in the future in light of the overall lack of ground water in the area. The post-mining land use for the area is livestock and grazing habitat. 13.10 Surface Water Control and Containment Facilities Information Design specifications for the VLF and associated drainage control structures, certified by a licensed professional engineer, are summarized above in Sections 6.0 and 9.0 of this Project Description and contained in Appendices 8 and 10 in Volumes V through VI and Volume VII, respectively, of this document. The Storm Water Management Plan for the Cresson Project will be updated as part of the MLE. A copy of the updated Plan will be • provided to the OMLR upon completion. 13.11 Surface Water Quality Data Regionally, surface water flows from the Cresson Project area are tributary to the Upper Arkansas River basin. At the mine site, surface water would flow into Grassy Creek, a tributary to Beaver Creek on the north side. Surface water would flow into Theresa Gulch and Bateman Creek which are tributaries to Wilson Creek, which flows into Fourmile Creek on the south. The drainages flowing west are Poverty Gulch, Squaw Gulch, and Arequa Gulch, from north to south. These streams are all tributaries to Cripple Creek, which also flows into Fourmile Creek. A discussion of surface water quality, including existing receiving stream standards, where applicable, is contained in Section 4.6.1. of the Project Description and Appendix 2, Volume II.of this document. Drawing G-2 in Exhibit G shows the surface water rights for a two-mile radius around the permit boundary. Section 4.6.1 and Appendix 2 contain flow and water quality. data for CC&V monitoring stations. The data include at least five successive quarters. 13.12 Water Quality Monitoring Plan A water quality monitoring plan for both surface and ground water is contained in Section 10.0 of this Project Description. • Cripple Creek & Victor Gold Mining Company Cresson Project Mine Life Extension 13-9
