provided graphically for all of 2011, but actual flow data figures (from <br />USGS station reports) were only provided for October through May for H -1 <br />and October through January for NF -1. OMI needs to revise the 2011 <br />AHR to provide numeric data for flow measurements for the full 2011 <br />water year at NF -1 and HN -1. <br />e. There is no flow data reported for NF -3 in 2011. OMI needs revise the <br />2011 AHR to provide data for flow measurements for 2011 at NF -3. <br />4. Groundwater Levels: Groundwater levels were within historic ranges with the <br />exception of SC -1, which is rising. This well is completed in the Rollins <br />sandstone formation, below and hydrologically isolated from the B and D seams, <br />so the rise in water level is not likely mine related. No explanation is offered by <br />OMI for this upward trend. <br />5. Groundwater Quality: <br />a. Significant increases were reported in Sulfate (SO4), Fe (both total <br />recoverable and dissolved), and Zinc (Zn) at SC -1 and phosphate (PO4), <br />nitrate /nitrite (NO3 /NO2), and TDS at SC -3. Under Rule 4.05.13(4)(c), <br />OMI should revise the 2011 AHR to interpret these values and <br />identify whether or not this is a mining related impact. <br />b. Bicarbonate (HCO3) is markedly decreased at SC -1 and SC -3 in 2011. <br />Under Rule 4.05.13(4)(c), OMI should revise the 2011 AHR to interpret <br />these values and identify whether or not this is a mining related <br />impact. <br />C�GIIIIII ["I, <br />a. Significant increases in PO4, Fe (both total recoverable and dissolved), <br />and Zn were seen at all three alluvial wells (BC -1, EC -14, and EC -15). <br />Under Rule 4.05.13(4)(c), OMI should revise the 2011 AHR to interpret <br />these values and identify whether or not this is a mining related <br />impact. <br />b. Wells BC -1 and EC -14 both show a decreasing trend in pH values. Under <br />Rule 4.05.13(4)(c), OMI should revise the 2011 AHR to interpret these <br />values and identify whether or not this is a mining related impact. <br />C. HCO3 is markedly decreased in BC -1, EC -14, and EC -15 in 2011. Under <br />Rule 4.05.13(4)(c), OMI should revise the 2011 AHR to interpret these <br />values and identify whether or not this is a mining related impact. <br />7. Springs: Both springs required to be monitored (SP -8 and SP -9) were dry. <br />
