expected, conductivity decreases with increasing flow rate in the rivers. This is due to snowmelt and rainfall runoff <br />and related dilution effects. <br />Plots of total recoverable iron measurements for the Williams Fork River are presented in Figures 58AK and 58AL for <br />upstream station WF -1 and downstream station WT-2, respectively. The comparisons of these data indicate that total <br />recoverable iron concentrations are nearly identical upstream and downstream of the mine on the Williams Fork <br />River. The annual means in some years show slight increases at the downstream station due to slightly higher <br />concentrations for the annual maximum total recoverable iron concentrations. However, water quality differences <br />appeared to be within the statistical variation at each location. Total recoverable iron generally increases with <br />increasing flow rate in the river. This is due to the increase in suspended solids, which includes forms of iron, which <br />appear in the analysis of total recoverable iron. <br />Plots of pH measurements for the Williams Fork River are presented in Figures 5 8A and 5 8A for upstream station <br />WF -1 and downstream station WT-2, respectively. The comparisons of these data indicate that there is no trend in pH <br />or observable difference in pH upstream and downstream of the mine on the Williams Fork River. <br />Plots of total suspended solids measurements for the Williams Fork River are presented in Figures 58AO and 58AP <br />for upstream station WF -1 and downstream station WT-2, respectively. The comparisons of these data indicate that <br />total suspended solids concentrations are nearly identical upstream and downstream of the mine on the Williams Fork <br />River. Total suspended solids increase with increasing flow rate in the river, as would be expected, due to increase <br />erosion and sediment transport. <br />Protection of Public Parks and Historic Places <br />No public parks are located within the permit or adjacent areas; therefore, the MCM operations will not affect any <br />public parks. Similarly, the operation will not affect any places included or eligible for listing in the National Register <br />of Historic Places. Because no public parks or historic places will be adversely affected by the MCM operation, this <br />section of the regulations is not applicable. <br />Surface Mining Near Underground Mining <br />MCM will conduct underground mining only. The only surface activity will be the ongoing reclamation and <br />management of previously mined and now abandoned strip pits. <br />TR14 -36 2.05 -47.1 Revised 03/20/14 <br />
