Peak Ranch Resource <br /> August 5, 2020 <br /> EXHIBIT G -WATER INFORMATION <br /> This exhibit discusses the water quality monitoring plan developed to protect the integrity of local surface and <br /> groundwater quality, and the water supply plan that will support the two phases of the proposed mining <br /> operations. Peak Materials,first and foremost, is committed to protecting the quality and quantity of water in <br /> the Blue River, in the alluvial aquifer underlying the permit property, and in nearby groundwater wells. <br /> Baseline water quality is already being monitored, both in the groundwater and in the Blue River. Monitoring of <br /> the groundwater table level is also taking place. This monitoring will continue during mining and through <br /> reclamation. Collected surface water and groundwater data can be found at the end of this exhibit. Peak <br /> Materials is committed to protecting the prevailing hydrological balance and water quality at the site. <br /> 1.0 GENERAL <br /> Peak Materials installed 11 monitoring wells on the property. Five monitoring wells (G-1 through G-5), located <br /> around the mining envelope, are used to evaluate pre-mining water quality while the other six monitoring wells <br /> (P-1 through P-6) are used to monitoring groundwater levels in the vicinity of the wetland area. See Exhibits <br /> C and F for the locations of the monitoring wells. Additionally,two stream sampling locations, one directly <br /> upstream and one downstream from the permit area along the Blue River, are also being sampled to <br /> determine a baseline for the water quality of the Blue River.Appendix G-1 contains the baseline surface water <br /> quality data and Appendix G-2 contains the baseline groundwater quality data gathered by Peak Materials to <br /> date. Peak Materials has also collected groundwater levels and the data are also presented in Appendix G-2. <br /> 2.0 WATER QUALITY PROTECTION <br /> The main concerns regarding water quality are potential impacts to surface or groundwaters from sediment, <br /> hydraulic fluids, or diesel fuel. Sediment will be controlled through the use of stormwater retention within the <br /> mine cell during Phase 1 or within the ground water pond during Phase 2.All surface runoff flow from the <br /> mining area will be directed towards the mine cell where it will collect and infiltrate into the gravel alluvium that <br /> comprises the deposit. Map C-2C shows a detail of the surface water runoff flow. Hydraulic fluids and diesel <br /> fuels will be contained within any vehicles using best practices of maintenance and regular inspections of <br /> vehicles, hydraulic lines, and any other potential sources of spills. Diesel is proposed to be stored on-site in <br /> double walled tanks,the additional wall acting as the required secondary containment. Furthermore, the tanks <br /> will be mobile so that they can be moved to be located away from exposed ground water. Inadvertent spills <br /> that occur during fueling or refilling operations will be cleaned up immediately utilizing spill kits located <br /> adjacent to all fueling areas. <br /> Water quantity, in the form of depth to water table, and water quality, in the form of the results of geochemical <br /> analyses,will be compared throughout the life of the mine to determine what effect, if any,the operation is <br /> having on groundwater as it transits the permit area. Great care will be taken not to injure vested water rights <br /> owned by third parties. Knowledge of existing water conditions on site, in the alluvial aquifer, in the Blue River, <br /> and in any wells within 600 feet of the operation will allow Peak Materials to identify possible impacts to third- <br /> party water rights. Given that the extraction of the resource will be by wet mining methods in Phase 2, there <br /> will be no dewatering via pumping or draining of the groundwater, thus the operation will have no injurious <br /> impact on wells located within or further than 600 feet of the mine. <br /> Groundwater and surface water samples will be tested quarterly for 62 constituents including dissolved <br /> oxygen, suspended/dissolved solids, and dissolved metals to evaluate and record the conditions of the water <br /> on-site. See Appendices G-1 and G-2 for complete list of constituents. <br /> The Blue River parallels the site and the existence of any old channels or oxbows of the river passing through <br /> the site are not known nor anticipated. Peak Materials will leave a 200-foot buffer between the proposed mine <br /> cell and the Blue River to minimize the risk of the river from entering the mining cell. <br />
