Raton Creek Mine -Energy Fuels Mining Company 2003 AHR -Page 2 Well levels for both monitoring wells aze presented graphically on Figures 1 and 2 for the Refuse and Iuppa Wells, respectively. The unusually low level at the end of the previous report yeaz (2002) is, however, under question. This level was monitored by a third party and may be in error. Monitoring results from the following periods indicated a water level consistent with the historic average. Water levels at the Iuppa Wel] averaged usual levels. The fluctuations are likely do to the landowner's use of the well and 'draw own' in relation to the timing of the sample monitoring. The approved ground water monitoring program adequately monitors potential impacts of mining on the ground water system. The data collected through the period of this report indicate that no significant ground water impacts have occurred as a result of mining. Surface Water and NPDES Dischazges Current and historic water quality data collected from the approved monitoring point on the Starkville Diversion are shown on water quality Table 4. Diversion flow measurements are summarized on Table 5. No surface flows were monitored in the permanent diversion during the reporting period. Monitoring data for Pond No. 1 outfall (NPDES 001) are summarized and shown on to Table 1 for the reporting period. Post-mining discharge monitoring parameters include flow, settleable solids, pH, and oil and grease under the approved Colorado Wastewater Discharge permit. No pond discharges were monitored in 2003 due to low precipitation and continued drought conditions. Only one, short term dischazge occurred during the report year which was too short in length of time for the operator to obtain a sample. The approved surface water monitoring program effectively monitors the impacts of mining operations on the surface water system adjacent to the Raton Creek Mine site. Monitoring data documented through the period of this report indicate no significant impacts to surface water as a result of mining operations. Precipitation Information Precipitation data was no longer collected as approved by the revision to the permit referenced above. In general, drought conditions continued through the 2003 reporting period. The one, short term dischazge of the pond and the lower water well levels which have decreased since the year 2000 reflect these conditions.
