17. Water Treatment Plant and Ponds <br />• Excess water from the underground workings will be pumped into a lined untreated water pond via <br />six-inch diameter HDPE pipe. The lined pond will be located just north of 5/]0 Road and south of <br />the sediment pond. Surface drainage overflow from the ore pad area will also be directed to this <br />pond. A portable, trailer-mounted water treatment plant will be installed immediately west of the <br />lined pond. See Map C-2. The plant will pump water from the synthetically lined collection pond <br />and treat the water with barium chloride and ferric sulfate to precipitate out radium and uranium. <br />The treated water will be dischazged into one of two synthetically lined ponds located immediately <br />north of the treatment plant. Each pond will have two cells. Precipitated metals and radionuclides <br />will settle out in the first cell and the second cell will collect the treated water prior to gravity <br />discharge into the ephemeral drainage located immediately west of the pond. The treatment plant <br />and ponds will be fenced and equipped with a locked gate to prevent unauthorized access. <br />Sampling and analysis of treated water will be conducted in accordance with a dischazge permit <br />• with the Colorado Division of Water Quality Control. <br />Details of the water treatment process aze discussed in Exhibit T and Appendix H. <br />18. Power Drop Locations <br />Map C-lA shows a permit area of 0.41 acres located approximately 1,100 feet southwest of the <br />Packrat portal area. This azea has been previously disturbed by past mining operations. The current <br />site is relatively flat and contains two abandoned power poles surrounded by a chain link fence and <br />an abandoned steel air receiver tank a short distance away. An existing borehole was drilled in the <br />past to allow power to enter the mine. Energy Fuels plans to use the same boring or install a new <br />cased 6-inch diameter hole to allow power to enter the mine. San Miguel Power will re-connect the <br />power to the site from poles in the surrounding area. As seen on Map C-lA, the site currently has <br />existing access roads that enter the pad azea from the south and the north. These roads will not be <br />part of the DRMS permit area. <br />L~ <br />Whirlwind Mine June 07 D-32 <br />
