r <br />Monitoring Freguencv <br />Bedrock Wells <br />1. Data submitted in July, 1995 indicates 1994 monitoring <br />requirements were met at sites 91-M001 and 91-M004 in the <br />Southwest Mining District. <br />2. The Division duly notes the missed measurements at the <br />remaining bedrock sites and the reasons-given for these <br />5 omissions. Please be aware that given the limited <br />scope of the bedrock monitoring, the Division anticipates <br />that the bedrock monitoring will be conducted in its <br />entirety in the future as per the approved plan. <br />Alluvial Wells <br />1. The Division has not received the required data for the <br />Fish Creek alluvial wells GWAP-3, 4, 5, 7 and 8 for the <br />October 1993 to December 1993 period. Please submit this <br />information. <br />Surface Water <br />1. Data submitted in July, 1995 indicates that the <br />monitoring requirements for the Fish Creek surface sites <br />were met. <br />springs <br />1. Data submitted for springs SW#1 and SW~2 indicates that <br />these springs were monitored on a semi-annual basis <br />rather than the required quarterly basis. Please explain. <br />Again, the Division will expect that spring 20-14 will be <br />monitored in the future as per the approved plan. <br />water Quantity and Oualitv <br />Bedrock Wells <br />1. Water levels in the Wadge overburden in FBR11A, which is <br />located some 10,000 feet from the subsided area, shows a <br />water level decline of approximately 60 feet starting in <br />1992. At 800 feet from the subsided area at well 91M006, <br />the water level decline is approximate 275 feet. A <br />decrease in TDS in well 91M006 is also noted, possibly <br />due to a gradient reversal due to adjacent underground <br />mining and subsidence. Observed drawdown is within the <br />range predicted in the Probable Hydrologic Consequences <br />(PHCj portion of the approved permit. <br />
