<br />ENERGY FUELS COAL, INC. <br />SOUTHFIELD MINE <br />QUAF.TERLY HYDROLOGY MONITORING PROGRAM <br />DATA SUMMARX <br />1989 AHR <br />(July, 1989 through June, 1990) <br />INTRODUCTION <br />Southfield continued to monitor surface and groundwater on a <br />quarterly basis during the reporting period. As in previous <br />annual reports, all data are summarized in tables along with all <br />available previous monitoring data. <br />SURFACE WATER <br />Field and laboratory data collected from the three (3) <br />surface water monitoring locations are presented in water quality <br />Tables 15 and 16, and Table 14, streamflow measurements. <br />No surface water flows were observed during this reporting <br />period. Both Newlin Creek and Oak Creek typically flow only when <br />spring runoff exceeds upstream diversion requirements. The lack <br />of observed surface flow reflects the minimal snowpack levels <br />this year. Magpie Creek, and ephemeral drainage, is a losing <br />stream system above the monitoring point, rarely exhibiting <br />surface flow. <br />Southfield attempted to collect hydrologic data from Second <br />Alkali Creek in advance of monitoring to be required upon <br />anticipated approval of Permit Revision No. 1. Although specific <br />surface water monitoring requirements have not been specified, <br />EFCI would collect field and laboratory data in agreement with <br />existing permit requirements. No surface f1o•as were observed, <br />however, and no documentation of monitoring is presented in this <br />report. <br />CONCLUSIONS <br />The required surface water monitoring program continues to <br />monitor the impacts of mining operations on the surface water <br />system in and adjacent to the Southfield Mine and Loadout areas <br />and its results indicate that to date no detrimental impacts have <br />occured. <br /> <br />
