longer requires this lease water for replacements. The lining of the Stroh Pit received approval <br /> from the State Engineers Office in a March 12, 1999 letter. A copy of this letter is provided in <br /> Appendix D. <br /> The Wagner/Kauffman#3 pit will use the Loveland lease for replacements when mining begins. <br /> The lease is not specific to a particular pit, but only to replacements in the Big Thompson River. <br /> Larry Howard of the City of Loveland was notified that the lease water is now for replacements <br /> at the Wagner/Kauffman Pit 43 instead of the Stroh Pit. <br /> The total consumptive use during mining operations at the Wagner/Kauffman Pit #3 was <br /> calculated to be 10.5 acre-feet for the year(Table 2). Green Ridge Glade Reservoir is located 14 <br /> miles upstream of the Wagner/Kauffman Gravel Pit. Assuming carriage losses of 0.25% per <br /> mile, total losses would be 4%. This results in a total replacement of 10.9 acre-feet to meet the <br /> mining stream depletion obligations and the transit losses (Column 4, Table 3). <br /> OPERATION OF PLAN <br /> This substitute water supply plan was developed under projected operations for the <br /> Wagner/Kauffman Pit #3. The actual depletions from exposed water surface areas and aggregate <br /> production could vary slightly from the numbers used for calculations in the formulation of this <br /> plan. Kauffman and Son, Inc. will utilize the "Monthly Accounting Form" found in Appendix B <br /> to calculate and report actual depletions incurred on a monthly basis at the Wagner/Kauffman Pit <br /> #3. The accounting form will be made available upon request. <br /> WELLS WITHIN 600 FEET <br /> District 4 Water Commissioner Don Brazelton completed a field inspection at the site for wells <br /> within 600 feet on July 8, 1999. He concluded that there are no wells registered with the State <br /> Engineers Office that are within 600 feet of the permit boundary of the Wagner/Kauffman Pit#3 <br /> site. <br /> CONCLUSIONS AND RECOMMENDATIONS <br /> • Consumptive uses for the pit include evaporation and water retained in product <br /> removed from the site. The annual consumptive use during mining is estimated at <br /> 10.5 acre-feet (Table 2). <br /> • Replacement water will be supplied from an existing lease of 11.0 acre-feet from the <br /> City of Loveland. The lease will consist of fully consumable water and will replace all <br /> depletions associated with the mining operation. <br /> • The applicant will use the attached accounting form to keep monthly records of water <br /> Page 4 <br />
