V. MINE SURFACE FACILITIES RECLAMATION PLAN <br /> V.A Water Quantity and Quality Control Plan <br /> V.A.1 Water Quantity Control Plan The principal source of water for the mine is a fresh water <br /> lagoon along the White River. Secondary sources are water pumped out of the alluvial wells, the <br /> mine and runoff trapped in sedimentation ponds. <br /> BME currently has adequate water rights to operate the facility. These are: <br /> a. Moon Lake Pipeline - Case Nos. W-29781CW236 and 90CW154, 6.0 cfs decreed absolute <br /> 7/20/71, 0.3 cfs conveyed to BME with point of diversion to well gallery, 1/12/82. The point <br /> of diversion was subsequently changed to the pump at the fresh water lagoon on 11/26/90. <br /> b. Deserado Mine Water System - Case Nos. 80CW493, 85CW117 and 89CW079, 0.5 cfs <br /> absolute, ground water mine excavation, 5/9/90. <br /> C. Gross-Nichols Ditch - Case Nos. CA617, CA624 and 91 CW021, not to exceed 0.333 cfs <br /> decreed absolute 5/5/92. The point of diversion is at the pump at the fresh water lagoon. <br /> d. Moon Lake-Staley Mine Pipeline and Reservoir, and Enlargement of Moon Lake-Staley <br /> Mine Pipeline and Reservoir. Case Nos. CA1269, W-2937, 80CW186, 84CW147, <br /> 88CW154 and 91CW036. Change of 0.3 cfs (conditional) to the fresh water lagoon pump <br /> for fully consumptive industrial and mining purposes. BME also has 180 cfs of conditional <br /> non-consumptive water right under these cases. <br /> The mine facility water system has been designed to recover, treat, and reuse most of the waste <br /> water produced by the facility. Only enough water is taken from outside sources to make up for <br /> unavoidable or accidental losses. The maximum amount of makeup water estimated to be required <br /> is 552 acre-feet per year or 0.763 cfs or 180,000,000 gallons. The figure was projected to be 598 <br /> acre-feet during the initial mine permitting. <br /> Sedimentation ponds and sumps are constructed to meet Section 4.05.6 requirements for the <br /> protection of the quality of runoff from areas disturbed by mining operations. Water storage rights <br /> are obtained prior to the construction of ponds that may retain runoff to impact senior water right <br /> holders. <br /> In order to operate the mine facilities at the production schedule envisioned, the mine needs a <br /> consumptive water right of 0.8 cfs diverted near the Staley-Gordon mine and water storage rights <br /> for four ponds with a total combined maximum capacity of 22.4 acre-feet and a total surface area of <br /> 6 acres. <br /> TR-72 (07/2019) V-1 <br />
