• <br /> <br /> <br />field data collected during 2001. Well SM-9 was undermined by Panel C during 1993 but showed no apparent impacts <br />in the field data collected during 2001. No anomalous water quality observations were appazent during 2001 at the <br />Steven's Gulch shallow groundwater monitoring wells. <br />Surface Water Monitoring Stations .SPRINGS <br />Eas! Roatcap Creek -Two springs were monitored in the East Roatcap Creek drainage (refer to Table 1 and Map No. <br />4-1) during 2001. Spring 30 had a measurable flow in April. Water quality parameters taken from the seep in Dime were <br />slightly elevated, probably due to low flow conditions. Spring 30 was first undemuned m April,1983. Spring 10-10 <br />had an elevated flow in April, probably a reflection of snowmelt and was then dry in June, September and December, <br />therefore, no laboratory analysis is available. Spring 10-10 was encompassed by the angle-of--draw of Panel Y during <br />October, 1993. Subsidence impacts were not apparent at either of these locations during 2001. <br />West Roatcap Creek -Four springs were monitored in the West Roatcap Creek drainage (refer to Table 1 and Map No. <br />4-1) during 2001. Spring 31 was monitored on a monthly basis and exhibited flows throughout the yeaz with the flow <br />tapering off in the fall. Water quality parameters were consistent with ranges previously established for this site. No <br />mining occurred within the watershed for this spring in 2001 and no mining impacts were evident. Spring 32 was <br />monitored monthly. Spring 32 exhibited flow throughout the year with the flow tapering off in the fall and winter. <br />Water quality parameters were consistent with last year's sampling. Spring 10-13 was monitored quarterly. Flows, as <br />a result of a seemingly dry yeaz, were reduced or non-existent and field parameters observed at this site were consistent <br />with baseline values. No mining occurred during 2001 in the Spring 10-13 watershed. Spring 14-4 was monitored <br />quarterly. Flows and field parameters observed at this site were consistent with previous values. No mining occurred <br />during 2001 in the Spring 14-4 watershed. <br />Steven's GulcH -One spring was monitored within the Steven's Gulch drainage (refer to Table 1 and Map No. 4-1) in <br />200E Spring 25 lies below an area of the East mine inactive since 1982. This site had no measurable tows in April, <br />June, September and December and field parameters were consistent with prior measurements. Spring 25 has been <br />identified as an adjudicated water right within the pernut azea. <br />Two springs with ponds in the Stevens Gulch drainage, Spring and Pond 13-5, Spring and Pond 13-6 were monitored <br />quarterly in 2001. Spring and Pond 13-5 was undermined during the last half of 1992. Spring and Pond 13-6 was <br />undermined dtuing the end of 1988. Spring 13-5 had no measurable flow throughout the year and Spring and Pond ] 3-6 <br />had a measurable flow only in April. <br />Terror Creek -Seven springs or springs with ponds aze found within the Terror Creek drainage (refer to Table 1 and <br />Map No. 4-1) were monitored during 2001. Spring and Pond 17 is outside the anticipated extent of mining activity. <br />Spring and Pond 20 and Spring and Pond 7-1 were undemrined during the East Pod development, panels EP-3 and EP-4. <br />All four springs have extensive data collected to characterize the typical hydrology at these sites. However, these <br />locations were identified and targeted by the Division as adjudicated water rights within the permit area. No adverse <br />mine related impacts or other irregularities were noted at any of these Terror Creek Springs. <br />Surface Water Monitoring Stations: STREAMS AND DITCHES <br />Monitoring of surface water stations during 2001 was concentrated in the Stevens Gulch and East Roatcap Creek areas <br />as these drainages had seen recent mining activity and were projected for further activity during the current permit term. <br />Overall, adverse impacts attributable to muting were not evident at any of [he monitored surface water stations (refer <br />to Table 1 and Map No. 4-I). Stations SW-5 (Stevens Gulch), SW-6 (East Roatcap Creek), and SW-10 (Terror Ditch), <br />exhibited normal flows and water quality parameters consistent with previous years data. No evidence of subsidence <br />impacts in these drainages was apparent. Mining occurred in the Stevens Gulch drainage upstream of site SW-5 during <br />1993 in Panel C. Panel C mining was designed and conducted to prevent the development of subsidence to protect the <br />waterway and certain structures in the vicinity. Data collected during 2001 shows these protective measures were <br />successful. <br />Surface Water Monitoring Stations: SMALL AREA EXEMPTIONS <br />The east mine fan level was defined as a small area exemption since drainage from this area (refer to Map 8-1) is not <br />conveyed to a sediment pond. Three sample points were defined at this location and sampled for conformance with the <br />
