EXHIBIT G WATER INFORMATION <br /> 1. General <br /> Mining of an alluvial deposit like the Ready Mix Pit will involve affecting local ground water and <br /> surface water. In general, any water encountered by operations will be rerouted away from onsite <br /> activities to protect its quality. Surface water from the surrounding area will be allowed to enter the <br /> pit. Surface water runoff from within the site will be routed to the mining pit as well. Ground water <br /> encountered during mining will be pumped out to the nearest reclaimed pond. <br /> 2. Surface Water <br /> Tomichi Creek, a tributary of the Gunnison River, is located over 800 feet southeast of the mining <br /> area. No ditches or laterals cross the permit property. Drainage within the permit area is mostly <br /> sheet and local channelized flow to the reclaimed ponds and Tomichi Creek.No wetlands are <br /> located within the disturbance area. Local drainage basins and drainage paths for before, during, <br /> and after mining can be seen on Maps C-1, C-2, and F. <br /> The 100-year floodplain crosses through the site.No permanent fill is being placed within the <br /> floodplain. The mining pits, and then remaining lakes, are sumps during storm events, reducing the <br /> severity of the storm flows in the immediate area. The floodplain can be seen on Maps C-1, C-2, <br /> and F,which are found in Appendix 2. <br /> The 100-YR 24-HR event for this site is 2.08 inches'. The reclaimed ponds will have five feet of <br /> vertical storage between the surrounding topography and the pond level,which is significantly <br /> more than the 100-YR rainfall that will fall upon the ponds. The surrounding areas will be <br /> revegetated to create the same drainage conditions as prior to mining. During mining, all disturbed <br /> areas will either drain to a pit, a reclaimed pond, or be self-contained.No runoff will discharge <br /> from the disturbed areas. <br /> 'NOAA Hydrometereological Design Studies Center,Precipitation Frequency Data Server <br /> (http://hdsc.nws.noaa.gov/hdsc/pfds/pfds_map_cont.html?bkmrk=co) <br /> Ready Mix Pit October 2017 G-1 X Grgp Lintlai and Assuriatw.Ptd.l' <br />
