Raton Creek Mine 2000 AHR -Page 2 Well levels for both monitoring wells are presented graphically on Figures 1 and 2 for the Refuse and Iuppa Wells, respectively. A review of water levels data shows steady levels in the Refuse Well during the reporting period. Water well levels at the Iuppa Well tended to Fluctuate similar to previous trends, and were lower on average. The Fluctuations are likely influenced by the landowner's use of the well, while the lower levels may reflect the low amount of precipitation during the reporting period. 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 Discharees Field and laboratory 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 repotting . period. Monitoring data for the one NPDES outfall for the reporting period are summarized and shown on to Table 1. Post-mining discharge monitoring parameters include flow, settleable solids, pH, and oil and grease under the approved Colorado Wastewater Discharge permit. A review of these data indicate that all discharges were within NPDES permit limitations. 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. Preci~tation Information Precipitation data for the reporting period is summarized and shown on Figure 3. Total precipitation for the year was below the average total documented in the permit application, and approximately 33 percent less than the previous year. Storm events tended were intermittent, similar to the previous reporting period, and not cause significant erosion or structural damage on the site. The lack of precipitation, however, inhibited vegetation growth during the middle and late growing season.
