Exhibit 42, Figures 58A and 58B. Plots of laboratory dissolved iron measurements for the Two Trout Creek <br />Sandstone wells are presented in Figures 58C and 58D and plots of field pH measurements are presented in Figures <br />58E and 58F. These plots of field conductivity, dissolved iron and pH measurements for the Two Trout Creek <br />Sandstone Wells do not indicate any trend which could be indicative of water quality impacts related to mining. <br />Dissolved iron concentrations show considerable variation, which may be due to sampling and sample preparation. <br />Iron and pH values are similar at the two wells. Conductivity levels in the Okie Plaza well are somewhat higher than <br />the levels in 9 Mine well as would be expected since the Okie Plaza well is deeper and further from the outcrop. <br />The declines in the piezometric levels in the Middle Sandstone observed in Figures 12 through 17, in Section 2.04 -7, <br />Hydrology Information, are apparently related to dewatering and subsidence associated with Mines 5 and 6. The <br />Permit Renewal No. 4 2.05 -40.1 Revised 3/5/03 <br />
