Water Information(coat.) Exhibit G <br /> Consumptive Water Use <br /> The current annual consumptive uses of water associated with <br /> the Fort Lupton Sand and Gravel Mine and aggregate production are <br /> described below. <br /> USES (2025) VOLUME <br /> Acre-feet <br /> 4% Moisture Loss in Material 26.49 <br /> Dust Control 0.75 <br /> Water Surface Evaporation 85.21 <br /> Total Consumption (Augmented) 112.441 <br /> Substitute Water Supply Plan <br /> Ground water depletions associated with L.G. Everist' s Fort <br /> Lupton Sand and Gravel Mining operation are currently covered <br /> under a substitute water supply plan (SWSP) pursuant to C.R.S. 37- <br /> 90-137, approved by the Division of Water Resources (DWR) for <br /> replacement of the ground water depletions due to mining. This <br /> plan is updated and renewed every 2 years. <br /> The Applicant will maintain a SWSP throughout the life of the <br /> mine. After completion and reclamation of all lined reservoirs <br /> there will be no long-term evaporative depletions. However, if any <br /> unlined open surface water areas remain at the end of reclamation, <br /> then a court-approved augmentation plan will be applied for before <br /> reclamation is complete. <br /> 100-Year Floodplain <br /> Portions of the Fort Lupton Sand and Gravel Mine are located <br /> within the 100-year floodplain of the South Platte River. The <br /> applicant has a Flood Hazard development Permit from Weld County <br /> for the original permit area. On 12/09/2008 Deere & Ault prepared <br /> a Flood Plain analysis (in Division' s file) showing that there <br /> will not be an appreciable increase in flood elevation due to the <br /> mine. The information provided in this report is applicable to <br /> the new areas as it lies within the South Platte alluvium <br /> immediately adjacent to the permit area. The location of the 100 <br /> year flood line on the affected lands was transferred from the <br /> 2023 updated FIRM Panels 08123C2102F and 08123C1915F to all maps. <br /> L.G.Everist, Inc.
