19 <br />EXHIBIT G -WATER INFORMATION <br />Overview <br />This section describes the existing water features in and nearby the proposed mining permit area, <br />potential impacts on water resources due to mining, and water requirements for the project. Local <br />surface water features in the vicinity of the project are shown on Exhibit B, Index Map and on <br />Exhibit C, Pre-Mine and Mine Plan Map. Wells potentially within 600 feet of the proposed <br />permit area are shown and will be described in the "Temporary Substitute Supply Plan" being <br />prepared by Applegate Group which will be submitted as part of this Exhibit and also submitted <br />to the Colorado State Engineer for approval. The entire permit area is located within the 100-year <br />floodplain of the Big Thompson River. <br />Mining of the proposed excavation area of the permit will be by the "dry-mining" Method, <br />pumping alluvial groundwater from within the areas to be mined. Mining will expose <br />approximately 2.5 surface acres the first year and 2 to 5 acres per year for the duration of the <br />operation. <br />Surface Water <br />The nearest major watercourses are the Big & Little Thompson Rivers, which flow <br />approximately 250 ft. from the east edge of the mining limit. Final discharge from de-watering <br />the excavation areas of the permit site will be made near the southeast corner of the permit area, <br />after clarification in a sump area, via an open trench to the Little Thompson River. Prior to any <br />discharge activity to the Little Thompson River, the operator will obtain a CPDES/Stormwater <br />discharge permit. . <br />Groundwater <br />The approximate locations of wells located within 600-feet of the permit boundary for the site <br />are shown and described in the accompanying "Substitute Supply Plan" submitted as part of this <br />Exhibit. <br />2RR app <br />CDMG 112 <br />
