Exhibit G <br /> Page 1 <br /> EXHIBIT G <br /> WATER INFORMATION <br /> Per Rule 6.4.7— Water Information • <br /> (1) If the operation is not expected to directly affect surface or groundwater systems,a statement of that <br /> expectation shall be submitted <br /> The Kersey Mine is not expected to directly affect either surface or groundwater systems. <br /> An existing manmade stock pond is located within the Permit Boundary but outside of the planned mine areas.The <br /> stock pond was historically filled using the nearby stock well that is planned for plugging and abandonment. The <br /> 0.38-acre stock pond has not been used in several years and water was absent during October 2023 wetland and <br /> waterbody surveys and during the May 31,2024 field visit.No other surface waters are in the Permit Area. <br /> The Kersey Mine Permit Area is generally isolated from offsite-sourced surface run-on from roadways.Based on the <br /> Barnesville,CO USGS topographic map,run-on/run-off is expected to follow the surface topography which slopes <br /> from the northwest(approximate elevation 4,780 feet above mean sea level(ft-amsl))to the southeast(approximate <br /> elevation 4,625 ft-amsl)with a gradient ranging from 0%to 9%.The general nature of the surficial soils(i.e.,silty <br /> sands(SM)to poorly graded sands with silt(SP-SM)with a rapid and high infiltration capacity)present at the <br /> location would preclude surface flow over any large distance with the exception of during heavy precipitation events <br /> (NRCS,2023). Therefore,impacts from run-on/run-off are localized.Operations at the Kersey Mine will not result <br /> in any significant impacts on surface water within,or adjacent to,the Permit Area. <br /> With respect to the localized(and/or regional)groundwater system,the Kersey Mine is not anticipated to have a <br /> significant effect on groundwater features.Four groundwater wells were identified within the permit area based on <br /> information available through the Colorado Department of Water Resources,including: <br /> • One well(Permit No.287429)located in the SE 1/4 of the SW 1/4 of Section 15 (near TMDZ-2 Area)is <br /> designated as a monitoring well and is reported to have a static water level of approximately 4,620 ft-amsl <br /> (30 feet below ground surface(ft-bgs)). This monitoring well is owned by Noble Energy and is associated <br /> with monitoring groundwater in response to a reportable release at an oil and gas facility.This oil and gas <br /> facility is outside of the planned mining area and will maintain a buffer during mining operations to <br /> protect the facility and on-site monitoring well. <br /> • One well(Permit No.310849)located in NW 1/4 of the NE 1/4 of Section 15 (Year 19 Area)is designated <br /> as a domestic well currently used for watering livestock and is reported to have a static water level of <br /> 4,605 ft-amsl(55 ft-bgs). This well will be plugged and abandoned prior to mining. <br /> • One well(Permit No. 319490)located in the NW 1/4 of the NE 14 of Section 14(near TMDZ-1 Area)is <br /> designated as a livestock watering source only and is reported to have a static water level of 4,616 ft-amsl <br /> (29 ft-bgs). This stock well is outside of the planned mining area and will maintain a buffer during mining <br /> operations if the well owner chooses to maintain the well through the life of the mine. <br /> Colorado Sand Company II,LLC <br /> Kersey Mine Construction Material Regular(112)Operation Reclamation Permit Application <br /> June 7,2024 <br />
