Colowyo, C1981-019, PR3 adequacy 3 February 25, 2011 <br />2. The groundwater lab parameter table in Section 4.05.13 indicates several metals will be <br />analyzed for the "total dissolved" concentration, rather than the "dissolved" concentration. <br />When analyzing a sample for the "total dissolved" concentration, will particulates of the <br />constituent be removed from the sample before performing the analysis? <br />Rule 2.04.7(2) Surface Water Information <br />The application is adequate with regard to this Rule. <br />Rule 2.04.7(3) Alternative Water Supply Information <br />1. The application is deficient with regard to any analysis or study to determine what, if any, <br />impact could occur to registered ground water users proximate to the mine dewatering <br />operations that will occur over the life of the mine. In particular, mining in the Collom Lite pit <br />will result in dewatering of the overburden to varying degrees from both pit dewatering and pit <br />development. Please provide permit text narrative discussing specific details regarding <br />dewatering and associated impacts, including estimates of the cone of depression, maps, cross- <br />sections and other information sufficient to reflect what impacts may occur to registered <br />owners of wells in the proposed permit and adjacent area. <br />Rule 2.04.8 Climatolosical Information <br />In application section Rule 2, page 47, CCC discusses collection of one year of meteorological <br />data beginning July 1, 2008 to June 30, 2009. In this section, there is no reference to the data <br />collected or the modeling conducted on the 2008-2009 data. Did CCC submit the July 1, 2008 <br />to June 30, 2009 meterologic data in the application? If the data has been submitted, please <br />reference in this section where the data can be located. Has the modeling been conducted using <br />the July 2008-June 2009 data? What were the results?
