<br />18.4. Water Treatment Plant and Tanks <br />Excess water from the underground workings will be pumped into a lined untreated water tank via a <br />buried six-inch diameter HDPE pipe. The lined tank will be located just north of 5/10 Road and south <br />of the sediment pond. Surface drainage overflow from the ore pad area will also be directed to this <br />tank. A portable, trailer-mounted water treatment plant will be installed immediately west of the <br />collection tank. See Map C-2. The plant will pump water from the synthetically lined collection tank <br />and treat the water with barium chloride and ferric sulfate to precipitate out radium and uranium. <br />The treated water will be discharged into one of two synthetically lined tanks located immediately <br />north of the treatment plant. Precipitated metals and radionuclides will settle out in the first tank and <br />the second tank will collect the treated water prior to gravity discharge into the ephemeral drainage <br />located immediately west of the tank. The treatment plant and tanks will be fenced and equipped with a <br />• locked gate to prevent unauthorized access. <br />Sampling and analysis of treated water will be conducted in accordance with Colorado Discharge <br />Permit System (CDPS) Permit Number CO-0047562 with the Colorado Division of Water Quality <br />Control. See Appendix L) <br />Details of the water treatment process are discussed in Exhibit T and Appendix H. <br />18.5 Construction QA/QC <br />The BLM and DRMS will be notified in writing at least 10 working days prior to the beginning of <br />construction of stormwater control features, the ore pad, and any additional structures. This will allow <br />the agencies the opportunity to conduct inspections prior to and during construction activities. A <br />detailed preconstruction report will be prepared by a licensed professional engineer and submitted <br />within 30 days of completion of the work or prior to commencing use, whichever date is less. <br />~J <br />Whirlwind Mine 07 (rev.
