GURAY_5LUER U/NES <br /> Response: The lines that are traveling to and from the tailing thickener are carrying a solid waste with <br /> non-detects for reagents and no secondary containment on the lines is required. If the lines were to break, <br /> the solids would be removed to final placement in the tailings facility. <br /> 30. For all sumps depicted in the various drawings throughout the entire facility, please provide a <br /> narrative or table identifying their location, pump capacity, reporting location and drawing sheet <br /> references to verify the details of each respective sump. <br /> Response:Please see attached Table 9. <br /> 31. Address the procedures related to spills or waste that cannot be reintroduced into the system as a <br /> method of disposal and which would require off-site disposal. <br /> a. Include a commitment to conducting TCLP testing of all waste prior to disposal in order to <br /> make a proper Hazardous Waste Determination. <br /> b. Commit to storing all waste in secondary containment while awaiting the TCLP test <br /> results. <br /> Response:Any material that leaves the mill circuit will be returned to the milling process. The only waste <br /> that will be generated by the milling process are the tailings. <br /> a. If some extraordinary event were to occur that would not allow material to be returned to <br /> the process, the mine commits to characterizing the waste and disposing of it in accordance <br /> with Colorado state regulations. <br /> b. Material that for some reason could not be returned to the mill circuit will be kept on <br /> secondary containment while awaiting characterization. <br /> 32. Regarding Process Water: <br /> a. Please state the anticipated total volume of processed water to be stored on site at any <br /> given time pursuant to Rule 6.4.21(6)(b)(i). Is there a storage tank location or is the total <br /> volume stored throughout the piping of the facility and the various equipment? <br /> b. Eventually the process water will need to be disposed of. How will the system be drained <br /> into trucks for transport off site? Rule 6.4.21(6) <br /> Response: <br /> a. There is a process water storage tank of 18,000 gallons.Should process water be required to <br /> be disposed of it would be characterized and disposed of in accordance with CPDHE <br /> regulations. <br /> b. The mill runs a water deficit and makeup water needs to be added to the system for it to <br /> function properly. No water will need to be trucked off site to be disposed of. Eventually, a <br /> water conditioning system might need to be added to the mill circuit under a future technical <br /> revision to deal with mineral build up in the water. <br /> 811-1 e <br />
