Terror Creek <br />Four springs located within the Terror Creek drainage (refer to Table 5 and Map <br />No. 4-1) were monitored during 1994. Spring & Pond 17 and Spring 1-5, are <br />located outside of the anticipated extent of mining activity. Spring & Pond 20, <br />Spring & Pond 7-1 were undermined during the East Pod development, panels EP-3 <br />& EP-4. All four springs have extensive data collected to characterize the <br />typical hydrology at these sites. However, these locations were identified and <br />targeted by the Division as adjudicated water rights within the permit area. <br />No adverse mine related impacts or other irregularities were noted at any of the <br />Terror Creek springs. <br />SURFACE FIA'~ MONITORING STATIONS -STREAMS AND DI7C]IFS <br />Monitoring of surface water stations during 1994 was concentrated in the Stevens <br />Gulch and East Roatcap Creek areas as those drainages had seen recent mining <br />activity and were projected for further activity during the current permit term. <br />In general, no adverse i~acts attributable to m;n;ng were evident at any of the <br />monitored surface water stations (refer to Table 5 and Map No. 4-1). Stations <br />SW-5, Stevens Gulch, SW-6, East Roatcap Creek, and SW-10, Terror Creek exhibited <br />- normal floras and water quality parameters consistent with previous years data. <br />No evidence of subsidence i~acts in these drainages was apparent. Mining <br />occurred in the Stevens Gulch drainage upstream of site Sw-5 during 1993 in <br />Panel C. Panel C m;n;nq was designed and conducted to prevent the development <br />of subsidence in order to protect the waterway and certain structures located <br />in the vicinity. Data collected during 1994 indicates these protective measures <br />were successful. <br />SURFACE Y~OI'~R MONI70RING SDITIONS -SMALL AREA E~TIONS <br />The East Mine fan level was defined as a small area exemption as drainage from <br />this area (refer to Map 8-1) is not conveyed to a sedirtent pond. Three sample <br />points were defined at this location and sampled for conformance with the NPDES <br />discharge alternative limitations requirements associated with discharges <br />oa.~urring as a result of precipitation events of less than the 10-year 24-hour <br />magnitude. In these instances, settleable solids and pH limitations must b° <br />met. During 1994 no samples were collected from these SAE points. <br />• MESAVEf~E FORMATION - BE[AW D SEAM C~tQIIa74~417ER MONI70RING <br />Well DH-65 is located in the East Roatcap (see Map No. 4-1) drainage and <br />7 <br />
