<br />July 8, 1992 <br />Page 7 <br />upon the increase in Foidel Creek alluvial conductivity, but is not the single causitive <br />factor. <br />MLRD Concern <br />Surface Water <br />Sites 800 and 8 show somewhat elevated values with regards to conductivity and/or <br />dissolved solids and/or sulfate; however, none are at levels of concern. Site 301 is a <br />good quality site which receives little or no runoff associated with CYCC mining <br />activities. High Spring values for iron are noted at site 1002 and to a lesser degree at <br />site 69; however, both sites receive the majority of TCC surface water flow and <br />neither shows any trend towards material damage at this time. <br />TCC Response <br />No response required. <br />MLRD Concern <br />Spring and Pond Discharge <br />High conductivity, TDS, sulfate, and manganese is noted in the measurements from <br />the Fish Creek Tipple springs; however, due to the low flow from these springs, no <br />impact to Fish Creek is apparent. High EC and dissolved solids are noted in Pond D <br />and Tipple Pond E. With the exception of Spring runoff, pond outflow is minimal and <br />no impact is apparent. <br />TCC Response <br />No response required. <br />MLRD Concern <br />Mine Inflow/Outflow <br />Water quality measurements of mine discharge water are similar to that of Wadge <br />Overburden historical values. This would support the CYCC conclusion that mine <br />inflow is impacted by the Wadge Overburden. The relatively small amount of mine <br />discharge (approx .15 cfs) is consistent with the low transmissivity of the Wadge <br />Overburden aquifer. No significant impact is noted as a result of the underground mine <br />discharge. <br />
