(b) Surface water quality and flow data have not been collected for the ephemeral swales <br />and washes draining the mine site. Any flow is of short duration for a few days each year, if at <br />all. <br />12. Water Quality Monitoring Plan <br />Any groundwater found in the monitoring holes constructed by Nuvemco will be sampled and <br />analyzed on a quarterly basis for five successive calendar quarters. In November 2009 Nuvemco <br />permitted the boreholes as monitoring wells. If significant water gathers in the Last Chance Pit <br />detention ponds, beyond that utilized for dust mitigation, it will be sampled and analyzed. <br />Nuvemco does have Storm Water Permit # COR-040241 from the Water Quality Control <br />Division, Colorado Dept. of Public Health & Environment for the Last Chance Mine. <br />13. Climate Data <br />Exhibit K describes the climate in the Permit area. Water balance is not expected to be a. concern <br />given the small area of mining and water retention. No stored chemicals or fluid containers are <br />present to be impacted by freezing temperatures. As tabulated in Exhibit K the average <br />maximum daily temperatures are well above freezing and evaporation rates are about four times <br />greater than the precipitation. The Last Chance Mine Permit area ranges from about 6300 to <br />6500 feet of elevation. Site specific wind data is not available, but the prevailing winds are <br />generally from west to east. <br />14. Geochemical Data and Analysis <br />The operations on the Last Chance Mine site are in an area where the native outcrops and rocks <br />contain low grade to high grade uranium ore at the surface throughout the Uravan Mineral Belt. <br />Easily accessed and higher grade ores have generally been discovered and some mining activity <br />has occurred at these sites. Chemical analyses of the ore and waste rock have been obtained and <br />included in Appendix B. <br />15. Construction Schedule Information <br />As described in the reclamation section Exhibit E, minimal soil and vegetation exists in the mine <br />area. The mine and most of the area to be impacted is on exposed bedrock or existing roads and <br />trails. The soils are described in detail in Exhibit I and Appendix D. <br />16. Quality Assurance and Quality Control Program and Measures <br />A licensed professional engineer experienced in construction of detention ponds, embankments, <br />etc., designed the sediment trap/ponds for construction in the Last Chance Mine area and will <br />provide QA/QC services as needed. <br />Last Chance Mine - April 2009 T-6
