Bowie Resources Limited $owie No. 1 Mine 1999 Annual Hydrology Report Two springs with ponds in the Stevens Gulch drainage, Spring and Pond 13-5, Spring and Pond 13-6 were monitored quarterly in 1999. Spring and Pond 13-5 was undermined during the last half of 1992. Spring and Pond 13-6 was undermined during the end of 1988. Spring 13-5 had a measurable flow only in June and Spring and Pond 13-6 had measurable flows in June and September. Terror Creek Seven springs or springs with ponds aze found within the Terror Creek drainage (refer to Table 1 and Map No. 4-1) were monitored during 1999. Spring and Pond 17 is outside the anticipated extent of mining activity. Spring and Pond 20 and Spring and Pond 7-1 were undermined during the East Pod development, panels EP-3 and EP-4. All four springs have extensive data collected to characterize the typical hydrology at these sites. However, these locations were identified and targeted by the Division as adjudicated water rights within the permit area. No adverse mine related impacts or other irregularities were noted at any of these Terror Creek Springs. Monitoring of Springs 7-10, 8-5, and 21 and Spring and Pond 22 continues in anticipation of future East Pod mining activities Surface Water Monitoring Stations: STREAMS AND DITCHES Monitoring of surface water stations during 1999 was concentrated in the Steven's Gulch and East Roatcap Creek areas as these drainages had seen recent mining activity and were projected for further activity during the current permit term. Overall, adverse impacts attributable to mining were not evident at any of the monitored surface water stations (refer to Table 1 and Map No. 4-1). Stations SW-5 (Stevens Gulch), SW-6 (East Roatcap Creek), and SW-10 (Terror Ditch), exhibited normal flows and water quality parameters consistent with previous years data. No evidence of subsidence impacts in these drainages was apparent. Mining occurred in the Stevens Gulch drainage upstream of site SW-5 during 1993 in Panel C. Panel C mining was designed and conducted to prevent the development of subsidence to protect the waterway and certain structures in the vicinity. Data collected during 1999 shows these protective measures were successful. Monitoring of SW-1, (West Terror Creek) and SW-2, (Upstream Terror Creek) continues in anticipation of future East Pod mining activities. Surface Water Monitoring Stations: SMALL AREA EXEMPTIONS The east mine fan level was deflrred as a small area exemption since drainage from this area (refer to Map 8-1) is not conveyed to a sediment pond. Three sample points were deSned at this location and sampled for conformance with the NPDES discharge alternative limitations requirements associated with discharges occurring because of precipitation events of less than the 10-year and 24-hour magnitude. In these instances, settable solids and pH limitation must be met. No samples were collected during 1999 from these SAE points. Pape 5
