activity and were prcojected for further activity during the uurertt permit term. <br />• Less ett~hasis was placed on surface water stations in Terror Creek and Coal GUlcir <br />where all mining activities had oea_~1 during 1986. In general, no adverse <br />impacts attributable to mining were evident at any of the monitored surface water <br />stations (refer to Table 5 arcs Map No. 4-1). Stations SS~1-5, Stevens Gulch, arcl <br />SW-6, Fast Roatcap Creek, exhibited normal flows and water quality parameters <br />consistent with previous years data. No evidence of subsidence impacts in these <br />drainages was apparent. Mining occurred in the Stevens Gulch drainage upstream <br />of site SW-5 during 1993 in Panel C. Panel C mining was designed and conducted <br />to prevent the development of subsidence in order to protect the waterway aryl <br />certain structures located in the vicinity. Data collected during 1993 indicates <br />these protective measures were successful. The remaining surface water <br />monitoring stations, with the exception of the Roatcap Creek sites Uf12C and LERC, <br />• are all located in areas outside of potential mining i~acts given mining <br /> develo~t to date. Little monitoring was corriucted at these sites during 1993 <br />other than to verify that water was still flowing and field parameters were <br />within normal ranges. The iJF32C and LERC sites continued to show an irregular <br />relationship between suspender] and dissolved solids concentrations above arcl <br />below the West mine facilities. TR-24 permanently and formally suspended further <br />monitoring efforts at eight of the thirteen surface water monitoring stations <br />monitored during 1993 and temporarily suspended further monitoring at an <br />additional two sites. <br />S~tFACE AATfR MfI~IIRCR.ING S17~TIQ~S - S'lD~iS, ARF7~ ~'FZRiS <br />'!he Orchard Valley Fast Mine fan level was defined as a small area exemption as <br />drainage from this area (refer to Map 8-lA) is not conveyed to a sediment pond. <br />• Three sample points were defined at this location and sampled for conformance <br />with the NPDFS discharge alternative limitations rsn ' ements associated with <br />16 <br />
