Als.Afelissa van der Poel <br /> RE:Substitute Water Supply Plan Amendment Request for the Fountain Pit(M-1982-155) <br /> July 10, 2020 <br /> Page 2 of 3 <br /> be used for dust control,aggregate production, and construction activities on and in the vicinity of the <br /> site. For the purposes of this SWSP,such water use will be considered 100%consumptive. <br /> Groundwater withdrawn from the Hanna Wells result in depletions to Fountain Creek, and such <br /> depletions are rarely in-priority. Replacement obligations for depletions resulting from operation of <br /> the Hanna Wells are set forth in the decrees for Case No. W-4376 and Consolidated Case Nos. <br /> 84CW202,84CW203,86CWI 18(b),and 89CW36. These cases indicate that depletions from pumping <br /> of the Hanna Wells are assumed to instantaneously impact Fountain Creek. Therefore,the additional <br /> depletions to potentially be covered by this SWSP amendment would equal the 250 acre-feet per year <br /> that Utilities may provide to Schmidt under the surplus water lease agreement. <br /> REPLACEMENT SOURCES <br /> In accordance with decrees for Case No. W-4376, Case No. 16CW3056, and Consolidated Case Nos. <br /> 84CW202, 84CW203,86CWI18(b),and 89CW36,Utilities augments depletions from pumping of the <br /> Hanna Wells using reusable sewered return flows released from the Las Vegas Water Reclamation <br /> Facility and/or nonsewered return flows. Utilities will continue to use such water as the replacement <br /> source for pumping from the Hanna Wells made pursuant to this SWSP. <br /> OPERATION OF PLAN <br /> Schmidt will continue to augment depletions that result from pumping of Well Permit No. 59834-F <br /> using replacement water provided by 20 FMIC shares in accordance with the currently approved <br /> SWSP. The accounting for this operation will remain unchanged. <br /> For this SWSP amendment,additional water will be delivered to the Fountain Pit by Utilities from <br /> the Hanna Wells. Such water deliveries will be metered, and will be used by Schmidt for dust <br /> control,aggregate production,and construction activities on and in the vicinity of the site. Utilities <br /> will have responsibility for reporting the pumping from the Hanna Wells, and augmenting the <br /> resulting depletions to Fountain Creek. Such augmentation will be performed with reusable <br /> sewered and nonsewered return flows in accordance with Case No. W-4376,Case No. 16CW3056, <br /> and Consolidated Case Nos. 84CW202, 84CW203, 86CW 118(b),and 89CW36. <br /> AMENDMENT CONCLUSION <br /> This SWSP amendment request is intended to allow water pumped from the Hanna Wells to be <br /> used on and in the vicinity of the Schmidt's Fountain Pit for dust control, aggregate production, <br /> and construction activities in accordance with a surplus water lease executed between Schmidt and <br /> Utilities. The depletions and replacements in the current approved SWSP will also continue as <br /> described in that plan. Schmidt intends that this amendment apply to the current SWSP approval <br /> period, which expires November 30, 2020. <br /> This completes the amendment request for the Fountain Pit SWSP.
