~. <br /> <br />Fish Creek site 1002 shows abnormally high TDS values in the <br />late summer, early fall time period. This would correlate to <br />abnormal discharge from the adjacent underground mine and is <br />not apparently related to C-81-071 mining activities. <br />Alluvial Wells <br />1. Wells 001-5-5, 009-5-10, and 008-AV-2 all show a continuing, <br />increasing trend in TDS since 1986. <br />Spoil Wells <br />1. 026-SP-2, 026-SP-3, and to a lesser degree 026-SP-1 all show <br />a continuing, increasing trend in Total Dissolved Solids. <br />Wadve Bedrock Wells <br />1. Wadge water levels in 026-79-4, 009-79-4, and 006-82-74C <br />appear to have recovered from adjacent surface mining and <br />approximate pre-mining levels. TDS in 006-82-74C is impacted <br />from spoil water migration from the upgradient area of this <br />well. <br />Summarv <br />Overall, impacts approaching material damage suspect levels are not <br />apparent to the current, prevailing hydrologic system. Salinity <br />levels in Foidel and Fish Creek continue to show elevated values <br />due to spoil spring discharges. Drawdown due to surface mining is <br />not apparent although higher salinity downgradient of surface <br />mining activities is noted. Due to limited use, no impact is <br />apparent. <br />PHC Revision <br />On November 25, 1994 the Division received revised pages for #C-81- <br />071 Probable Hydrologic Consequences Section. Apparently, these <br />pages are in response to a August 27, 1993 request (AHR file) by <br />the Division for CYCC to revise the PHC section for both #C-81-071 <br />and #C-82-056. While the Division appreciates CYCC following up on <br />this request, we have to ask that this material be submitted in the <br />normal fashion which includes the proper application form and <br />appropriate public notice. Please submit the appropriate items so <br />the Division can call this application complete for the purposes of <br />filing. This information can be accepted as a technical revision. <br />If you have any questions, please call me. <br />i <br />Sin re <br />~n <br />K A. rham <br />Environmental Protection Specialist <br />
