EXHIBIT G <br /> Water Information <br /> The proposed permit area is located in the southwest quarter of Section 22, Township 11 North, <br /> Range 67 West of the 6th Principal Meridian, Weld County, Colorado. The proposed permit area <br /> includes 166.1 acres. <br /> Introduction <br /> Lone Tree Creek, an ephemeral drainage system, bisects the southern portion of the proposed <br /> permit area from west to east. There are no other surface water resources near the site (see <br /> Exhibit C-4, Water Resource Map). <br /> The Lone Tree Creek drainage does not have an associated regulatory floodplain within the <br /> proposed permit area. Because of the incised nature of the creek, wetland communities appear to <br /> be restricted to the channel and immediately adjacent areas, with very steep and rapid transitions <br /> to uplands. Several shallow swales and head-cut erosion gullies drain to Lone Tree Creek within <br /> the proposed permit area, but no apparent defined channels or wetlands exist within these swales <br /> and gullies. <br /> Known Colorado Division of Water Resources registered and/or unregistered groundwater wells <br /> within 600 feet of the proposed affected area are illustrated on Exhibit C-4, Water Resource <br /> Map. However, the proposed mining operation does not anticipate encountering groundwater <br /> and no impacts to the surrounding groundwater hydrology are expected. Review of the <br /> construction logs from wells within 600 feet of the proposed permit area indicate static <br /> groundwater levels during well construction and pump installation to be between 20 feet and <br /> 50 feet below the ground surface. As stated previously, the aggregate deposit on the Carr Pit East <br /> site is expected to be relatively shallow, reaching a maximum depth of only about 12 feet below <br /> the ground surface. Additionally, non-mining related excavations on the property that extend to a <br /> depth below the aggregate deposit did not encounter groundwater. <br /> Groundwater on the Carr Pit East site will not be exposed during mining or reclamation. If <br /> groundwater is encountered, the area will be backfilled to a minimum two (2) feet above the <br /> normal groundwater elevation and a well permit and approved augmentation plan will be <br /> obtained from the Colorado Division of Water Resources before groundwater is exposed. <br /> Potential Mining and Reclamation Impacts <br /> The proposed mining operation will have no effect on site water resources. Water is primarily <br /> used for dust control and shall be trucked from off-site sources, including a permitted well on the <br /> existing Tucker Aggregate Pit (M-1980-002). See attached Office of the State Engineer well <br /> permit application and revised conditions of approval. Water use for washing of product <br /> materials is not anticipated. As discussed in previous sections, the operation is not expected to <br /> encounter groundwater during mining and stormwater will not be retained in the active mine pit <br /> or in the reclaimed pit area. <br /> Carr Pit East <br /> DRYS 112 Permit Application Page 18 <br />
