Raton Creek Mine <br />2001 AHR -Page 2 <br />Well levels for both monitoring wells are presented graphically on Figures 1 and 2 for the <br />Refuse and Iuppa Wells, respectively. A review of water levels data shows steady, slightly <br />declining, levels in the Refuse Well during the reporting period. Water well levels at the <br />Iuppa Well remained relatively steady around the 14-feet level, and were lower than the <br />historic average. The fluctuations are likely influenced by the landowner's use of the well, <br />while the lower levels may reflect the low amount of precipitation during the reporting <br />period. <br />The approved ground water monitoring program adequately monitors potential impacts of <br />mining on the ground water system. The data collected through the period of this report <br />indicate that no significant ground water impacts have occurred as a result of mining. <br />urface Water and NPDES Dischazges <br />Field and laboratory data collected from the approved monitoring point on the Starkville <br />Diversion aze shown on water quality Table 4. Diversion flow measurements are summarized <br />on Table 5. No surface flows were monitored in the permanent diversion during the reporting <br />period. <br />Monitoring data for the one NPDES outfall for the reporting period are summarized and <br />shown on to Table 1. Post-mining dischazge monitoring parameters include flow, settleable <br />solids, pH, and oil and grease under the approved Colorado Wastewater Discharge permit. A <br />review of these data indicate that all discharges were within NPDES permit limitations. <br />The approved surface water monitoring program effectively monitors the impacts of mining <br />operations on the surface water system adjacent to the Raton Creek Mine site. Monitoring <br />data documented through the period of this report indicate no significant impacts to surface <br />water as a result of mining operations. <br />Precipitation Information <br />Precipitation data was no longer collected as approved by the revision to the permit <br />referenced above. In general, dry conditions, which became drought conditions, prevailed <br />during the reporting period. The absence of pond dischazges and the lower than average water <br />well levels reflect these conditions. <br />
