The source of water for the pond will be from the mine treatment system. The flow through <br />this system has been 10 to 30 gallons per minute since 1995 when the discharge from the <br />No. 3 mine was piped to the treatment ponds. This has been an adequate volume of water <br />to provide a reliable source of water for the pond. <br />Ditch A, as shown on drawing D-4-8, is utilized to convey water from the treatment system <br />to the refuse pond. Since Ditch A is an integral component of the water supply system for <br />the refuse pond, it is a permanent feature so it was not reclaimed. <br />Water Division No. 5, Case No. W-2979 granted the No. 1 Mine a water right for 101 <br />gallons per minute with an appropriation date of June 30, 1963. Water Division No. 5, <br />Case No. W-2980 granted the No. 3 Mine a water right for 21 gallons per minute with an <br />appropriation date of December 31, 1962. These water rights should be adequate to <br />satisfy state requirements for storing water in the sediment pond. <br />Rule 4.05.9(1)(a) requires the operator to demonstrate the quality of the impounded water <br />is suitable on a permanent basis for its intended use. Discharge from the mine water <br />treatment system is analyzed in June of each year for pH, conductivity, temperature, TDS, <br />TSS, Bicarbonate, Calcium, Chloride, Copper, Iron, Magnesium, Manganese, Sodium, <br />Sulfate and Zinc. Results of the analysis are presented in the annual hydrology reports. <br />In order to leave the sediment pond in place it must conform to the requirements of Rule <br />4.05.9. Following is a discussion of the sediment pond as it relates to Rule 4.05.9. <br />4.05.9(1) Permanent Impoundments <br />(a) The water impounded will be effluent from the treatment ponds which will be <br />suitable for wildlife use. Wildlife and cattle have consumed water from the <br />treatment ponds since they were constructed in 1988. The effluent also meets <br />applicable State and Federal water quality standards. <br />(b) The level of water attainable in the pond is unknown at this time. The source of <br />water for the pond is discussed above. <br />Permit Renewal 4 -iv (Rev. 03/13) <br />
