• within previously established ranges for the 1995 Water Year with the exception of high hardness and TDS values being measured in September at site 900. SPOiL SPRING MONITORING The spoil spring monitoring program was initiated in 1986 and is conducted annually. In accordance with the approved plan, the annual mine wide survey is conducted during May with springs measured for flow and field parameters. If a spring is discharging at or above 35 gallons per minute it is monitored throughout the remainder of the year in accordance with the monitoring plan. During the 1995 Water Year monitoring effort, no spoil springs were observed producing flow sufficient to require additional sampling (se Table 17). Two measurable flows were encountered although the monitoring effort was hindered by the extremely wet conditions prevalent in the field at the time of the survey. Three previously measured springs, M3A2, M3SOVB, and M30DT, could not be discerned from surface runoff associated with saturated ground conditions. EFFLUENT MONITORING Two sediment ponds (Pond M3N -Site 24; Pond M3S -Site 76) are monitored as part of the Mine 3 • approved program. Pond M3N (Site 24) is located at the reclaimed area immediately north of the confluence of Foidel Creek and Middle Creek to control runoff from reclaimed areas of the abandoned Middle Creek underground mine. Pond M3N (Site 24) is subject to the effluent limitations detailed in NPDES Permit No. COG-850013. Pond M3S (Site 76) is located south of the confluence and east of Middle Creek to control runoff from reclaimed areas east of Middle Creek. Pond M3S (Site 76) is subject to the effluent limitations detailed in NPDES Permit No. CO-0027154. Sites 24 and 76 (See Tables 14, 14a, IS and 15a) discharged only in response to spring runoff during the 1994 Water Year. Discharges occurred in conformance with the established NPDF.S effluent limitations. Figures 28 and 29 provide graphical representations of the field conductivity values measured for these sites during the 1995 Water Year. All values were within the expected range of readings previously experienced. CONCLUSIONS No significant hydrology impacts attributable to activities or developments at Mine No. 3 are observed to have occurred during the 1995 Water Year. Spoil spring discharges remained negligible and, therefore, did not constitute a significant portion of discharge from the Mine No. 3 area with any potential to impact off- site areas. The previously discussed trends of elevating field conductivity measurements and TDS • concentrations in the surface water sites and closely associated alluvial wells are likely attributable to activities occurring upstream from Mine No. 3. These Vends were less pronounced during 1995. CYCC -6-
