x <br /> EXHIBIT G <br /> Water Information <br /> The information in this Section is intended to satisfy the requirements outlined in Section 6.4.7 of the Colorado Mined <br /> Land Reclamation Board's Construction Material Rules and Regulations. <br /> (1) If the operation is not expected to directly affect surface or groundwater systems, a statement of that expectation <br /> shall be submitted. <br /> This site is directly adjacent to the Brantner Ditch, Brighton Ditch and the South Platte River.The Brantner Ditch,the <br /> Brighton Ditch and South Platte River will not be disturbed because of the mining and reclamation activities on the <br /> site. <br /> (2)If the operation is expected to directly affect surface or groundwater systems,the Operator/Applicant shall: <br /> (a)Locate on the map(in Exhibit C)tributary water courses, wells,springs, stock water ponds, reservoirs, and <br /> ditches on the affected land and on adjacent lands where such structures may be affected by the proposed <br /> mining operations. <br /> Please see Exhibit C Pre-Mining Maps for the location of all tributary water courses,wells,springs,stock water <br /> ponds, reservoirs,and ditches on the affected land and on adjacent lands where such structures may be <br /> affected by the proposed mining operations <br /> (b)Identify all known aquifers <br /> The Tucson site is underlain by the Upper Arapahoe Aquifer(George VanSlyke,et. al. 1988, Geologic Structure, <br /> Sandstone/Siltstone Isolith, and Location of Non-Tributary Ground Water for the Arapahoe Aquifer, Denver <br /> Basin, Colorado. Denver Basin Atlas No.3, DBA-3. Colorado Division of Water Resources,Office of the State <br /> Engineer.) <br /> (c) Submit a brief statement or plan showing how water from de-watering operations or from runoff from <br /> disturbed areas,piled material and operating surfaces will be managed to protect against pollution of either <br /> surface or groundwater(and, where applicable, control pollution in a manner that is consistent with water quality <br /> discharge permits), both during and after the operation. <br /> The slurry wall for the West and East cells of State will be installed at the beginning of operations at the site. <br /> Water from the initial dewatering operation and runoff from disturbed areas, piled material and operating <br /> surfaces will likely be diverted to the settling pond for detention and cleansing. The South cell(Phase 1)will be <br /> wet-mined with concurrent dewatering;dewatering trenches will be located around the perimeter of the current <br /> mining cell in the West(Phase 2)and East(Phase 3)cells. Settling occurs in the trenches, and if necessary, <br /> settling ponds will be constructed at a point prior to discharge. Discharges will be directed to the South Platte <br /> River, at various points as designated within a State of Colorado, Division of Water Resources, Colorado <br /> Discharge Permit System (CDPS)permit. Monitoring of dewatering will be conducted in accordance with the <br /> CDPS discharge permit,which sets forth formal monitoring parameters including weekly visual monitoring for oil <br /> and grease. In accordance with the CDPS permit requirements, a Stormwater Management Plan(SWMP)will <br /> also be developed for this site. The SWMP identifies potential sources of pollution that may reasonably be <br /> expected to affect the quality of stormwater runoff from areas around the site;and describes the implementation <br /> practices to be used to reduce the pollutants in stormwater discharges associated with the facility. <br /> Aggregate Industries Tucson South Resource <br /> Permit#M-2004-044112 Permit Amendment <br /> Page G-1 <br />
