Exhibit G <br /> Page 7 <br /> surface or groundwater(and, where applicable,control pollution in a manner that is consistent with water <br /> quality discharge permits),both during and after the operation. <br /> Due to the nature of the deposit(eolian sand)and the limited likelihood of encountering free water conditions <br /> (i.e.,rapid releases or significant flowing seeps,etc.),active de-watering is not anticipated in conjunction with <br /> mining operations. <br /> To the extent saturated conditions are encountered which may affect mining operations(i.e.,minor seeps, <br /> saturated zones(e.g.,"aquicludes"),or precipitation effects(originating as run-on or"footprint"precipitation), <br /> water near the mine wet plant will be routed to the"holding cells",a proximal localized low area southeast of <br /> the mine wet plant,where it will be allowed to naturally infiltrate into the underlying porous soils and/or <br /> evaporate. Water near mine pits will be routed to the mine pits and allowed to naturally infiltrate. Water <br /> accumulation within mine pit areas during mining may be routed at the pit floors to in-pit sumps or via other <br /> diversional features to minimize saturation in the vertical mining zones. <br /> All aspects of run-on and/or run-off management will be addressed in an appropriate manner through the <br /> administration of the facility's CDPS General Construction Stormwater Permit(COR400000)during facilities <br /> construction and the CDPS General Permit(COG500000)for Discharges from Sand and Gravel Mining and <br /> Processing, if needed,once operational.This will include the implementation of all appropriately engineered <br /> "control measures"(formerly"best management practices")based on 25-year,24-hour design storm event,as <br /> defined within the respective Stormwater Management Plan(s)(SWMPs). <br /> The facility will not be subject to any process water discharge permit as all plant operations will be fully <br /> contained and will employ maximum recycling of all process waters within the process circuit. Thus,the <br /> facility will be operated as a"zero-discharge"facility. <br /> (3) The Operator/Applicant shall provide an estimate of the project water requirements including flow rates <br /> and annual volumes for the development,mining,and reclamation phases of the project. <br /> CSC anticipates minor water usage during the "development"phase,as such usage will likely be limited to dust <br /> suppression and/or geotechnical(i.e.,moisture content additions to achieve specified compaction criteria, etc.) <br /> requirements associated with facility construction. At this juncture,CSC estimates this usage to be 30,000 to 50,000 <br /> gallons per day(gpd)for an anticipated 3 to 10 months. <br /> CSC has estimated that the Kersey Mine processing plant's in-circuit water capacity will be approximately 430,000 <br /> gallons in total, in order to sustain operations at a rate of approximately 11,500 gallons per minute(gpm).Maximum <br /> recycle is employed in the process;therefore,make-up water requirements are anticipated to be approximately 8% <br /> of total,or 920 gpm,with make-up requirements largely attributed to evaporative and other process-related losses as <br /> well as the residual moisture content in process waste fines,etc. The plant water supply will be provided directly to <br /> the plant facilities,with storage capacity also available within the process sumps,clarifier unit,and the 50,000- <br /> gallon capacity recycle water tank. <br /> In addition to processing requirements(primarily washing, scrubbing, and screening of the sand product(s),water <br /> usage will also occur with respect to fugitive dust control on haul roads(estimated at 32,000 gallons per day),and <br /> other routine,but minor uses. <br /> Colorado Sand Company II,LLC <br /> Kersey Mine Construction Material Regular(112)Operation Reclamation Permit Application <br /> June 7,2024 <br />
