<br />{' <br />A review of the monitoring data for the period of this report indicates that no <br />subsidence is occurring at the ranch structures or the Newlin Creek point. Subsidence <br />was detected at Monument ]along the Florence Water Line. As a result of recent <br />mining operations, Monument I has displaced approximately 2.5 feet as compared to <br />the previous reporting period. This displacement is comparable to the 1.56 feet of <br />displacement measured at Monument E. Monument E displaced soon after mining <br />occurred in 1987, and has been relatively stable since that time. These subsidence <br />measurements are within the maximum value of 2.79 feet as predicted in the permit <br />application. There are no indications that subsidence due to mining is adversely <br />affecting operation of the Florence Water Line. <br />Subsidence monitoring of strictures indicates that subsidence is occurring only at <br />locations along the water line, and that the magnitude of displacement is within <br />predicted values. Only minor additional subsidence is expected to occur at the <br />structure monitoring locations. <br />
