specific discharge occurrences. Applicable permits include No.'s CO-0027154, CO-0036684, and CO- <br />L 0042161. Figures 86 through 89 provide graphical representations of Water Year flow rate and field <br />• conductivity data for Pond D atthe Foidel Creek Mine and for Pond E atthe Fish Creek Tipple. Figure <br />90 depicts period of record total recoverable iron data for Pond E. <br />MINE INFLOW MONITORING <br />The inflow to the underground mine is monitored in two ways. The flow rate and water quality of the <br />discharges from the mine (Sites 109 and 115) are monitored before entering Pond D or Fish Creek <br />respectively. In addition, an annual mine inflow study is performed. The 1995 Mine Inflow survey was <br />conducted during December 1995. During the inflow study, flow rates and field parameters are recorded <br />for measurable inflows into the accessible areas of the mine. Results of the 1994 study are presented as <br />Figure 93. Historical mean flow rate information for sites 109 and 115 is presented on Table 35. During <br />1995, the mean discharge rate decreased again relative to recently recorded figures primarily due to a pump <br />malfunction which caused site 115 to remain essentially inactive during the last part of the year. <br />SUMMARY <br />No significant unexpected hydrology impacts attributable to the acfivi6es or developments at the Foidel <br />Creek Mine are observed to have occurred during the 1995 Water Year. The previously noted declining <br />water level trend in Wadge Overburden well 91M006 appears to have stabilized during 1995. This trend <br />may be related to localized dewatering of the formation as a result of mining activities in the vicinity. No <br />water quality degradation is noted for the Wadge Overburden formation as a result of evaluafing data <br />collected during 1995. <br />Water levels in the monitored Twentymile Sandstone wells remained comparable to previously collected data <br />and stable. No significant water quality influences are noted to be evident in field data obtained during <br />1995. <br />Localized dewatering of the Trout Creek Sandstone appears evident in the vicinity of well 001-83-106 <br />although levels remain stable. A declining water level trend was again noted to be apparent at well 001-83- <br />107 although measurements appear to be stabilizing. Well monitoring efforts at FCM M2 during 1995 <br />yielded mixed results. Water quality appeared to improve indicating well potential contamination from <br />sealing efforts was improving, however, water levels taken from the site remained erratic and inconsistent <br />with historical data. The water levels returned by this site during 1995 are again noted to be markedly lower <br />than levels previously returned from well 006-83-48C. No readily apparent water quality impacts associated <br />~.~ with mining are noted for the Trout Creek Sandstone aquifer based upon data collected during 1995. <br />-11- <br />
