Energy Fuels Coal, Inc. <br />Southfield Mine <br />• <br />QUARTERLY HYDROLOGY MONITORING PROGRAM <br />DATA SUMMARY <br />1994 ANNUL HYDROLOGY REPORT <br />INTRODUCTION <br />This section of the 1994 AHR presents all surface and ground water data collected at the <br />Southfield Mine from 1979 through the end of the reporting period (June 30, 1995). <br />Discussion of these data, including potential impacts and trends, follows below. <br />SURFACE WATER <br />Field and laboratory data collected from approved monitoring points on Newlin, Oak, Magpie <br />and Second Alkali Creeks are shown on water quality Tables 15, 16, 17, and 1 S. Stream flow <br />measurements for these monitoring locations is summarized on Table 14. <br />Stream flow occurred and was sampled on at least one occasion at each of the stream <br />monitoring points. Streamflow persisted for an um~sually long period in all the monitored <br />streams during the second quarter of 1995. These conditions resulted from the high <br />precipitation levels experienced during this period, previously mentioned in this report. <br />Although Second Alkali Creek experienced less sustained flow than the other monitored <br />creeks, EFCI did obtain a sample during April 1995. This sampling satisfies the requirements <br />of permit Stipulation No. 15. <br />Water quality in the monitored creeks, based on the attached data, shows no unusual or <br />detrimental trends. Insufficient data for Magpie Creek and Second Alkali Creek exist at this <br />time to determine water quality trends. Data for Newlin Creek and Oak Creek indicate that <br />levels of TDS, TSS, Ca, Nitrate, bicarbonate and Sulfate are lower or on average with <br />previous monitoring periods. Heavy metals for these two creeks are within acceptable levels <br />as compared to previous yeas data. No deterioration of Newlin Creek or Oak Creek is <br />apparent from the water quality data collected to date. <br />The approved surface water monitoring program effectively monitors the impacts of mining <br />operations on the surface water system adjacent to the Southfield Mine and loadout site. <br />Monitoring data documented through the period of this report indicate no significant impacts <br />to surface water as a result of mining operations. <br />n <br />f, J <br />
