G-1 <br /> EXHIBIT G <br /> WATER INFORMATION <br /> ? d <br /> Per Rule 6.4.7— Water Information, CSC provides the following: <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 Keenesburg No.2 Mine is not expected to directly affect either surface or groundwater systems. <br /> With respect to the localized surface water regime,the Keenesburg No.2 Mine Permit Area is generally <br /> isolated from offsite-sourced surface run-on due to the presence of anthropogenic features(i.e., Weld <br /> County Road 59,located along the full extent of the western Permit boundary),regional and localized <br /> topographic characteristics (i.e., higher elevation features to the south that either preclude run-on <br /> potential or otherwise concentrate/divert run-on/run-off into wetland features present exterior to the <br /> proposed mining area), and the general nature of the surficial soils (i.e., rapid and high infiltration <br /> capacity)present at the location. <br /> With respect to the localized(and/or regional)groundwater system,the Keenesburg No.2 Mine is not <br /> anticipated to directly affect groundwater features (or systems) of significance due to the fact that <br /> mining depth will be limited to the economic depth profile of the sand resource,which is anticipated to <br /> range from approximately 20-ft.to 30-ft.maximum depth in most areas. No significant or economically <br /> exploitable groundwater resources have been identified as being present within the proposed mine plan <br /> area or the all-encompassing Permit Area. <br /> Due to the nature of the sand deposit (eolian), there are random and isolated "saturated lenses" that <br /> have been encountered at various locations across the Permit Area in exploratory drilling;however,in <br /> virtually all instances these limited extent features have been associated with localized, sub-surface <br /> lenses of sand altered by a high silt and/or clayey content, which tend to function as "aquicludes" or <br /> "aquitards". As defined in the online Geology Dictionary (www.geology.com), an "aquiclude" is <br /> defined as follows: <br /> Aguiclude: "The opposite of an aquifer. An aquiclude or aquitard is a subsurface rock, soil, or <br /> sediment unit that does not yield useful quantities of water. It may be porous and capable of <br /> Keenesburg No. 2 Mine-112 Reclamation Operation—November 22, 2019 <br />
