l t • L Energy Fuels Coal, Inc. Southfield Mine QUARTERLY HYDROLOGY MONITORING PROGRAM DATA SUMMARY 1992 AHA 1. introduction This report presents all surface and ground water data collected at the Southfield Mine for the reporting period July 1, 1992 through June 30, 1993. This section of the 1992 AHR presents summarized monitoring data, from 1979 to present, and a discussion of potential hydrologic impacts. 2. Surface Water Field and laboratory data collected form monitoring points on' Newlin, Oak, Magpie and Second Alkali Creeks are shown on water quality Tables 15, 16, 17, and 18. Stream flow measurements for these monitoring locations is summarized on Table 14. Stream flow was observed and sampled at all but the Second Alkali Creek points. Surface flow in Second Alkali Creek seldom, occurs due to the small drainage basin above the monitoring point and the prevailing dry streambed conditions. Stream flows. in the, remaining monitored creeks reflected the elevated storm activity' during the summer of 1992, and the moderate anowpack accumulation i during the following winter. A review of the quality data collected during the reporting period and compared with previous periods indicate no significant changes in water quality. i The required surface water monitoring program effectively monitors the impacts of mining operations on the surface water system adjacent to the Southfield Mine and loadout operations.i Monitoring data documented through the period of this report] indicate no significant impacts to surface water as a result of, mining operations. 2. Ground Water Field and laboratory data collected from monitor wells MW-B, MW-10, MW-16, HW-23, and MW-65 are summarized as described below. All data was collected in compliance with the approved monitoring program.. Water quality data for all wells except HW-8 are shown •in summary' on Tables 10, li, 12, and 13. ,A ieview'of these data as ' , J.:~:.i ... .. r ~'.,. . ~:
