• categories of sampling frequency, "Regular" monitoring that is done continuously, and "Contingent" monitoring <br />that is done only when there is a discharge from underground mine pumping. The precise timing of all sampling <br />may vary somewhat from Table A due to seasonal weather conditions. <br />Prior to the approval of TR-38, TR35 (May 2000) required monthly flow and field parameter monitoring, with <br />quarterly water quality sample collection. All required monitoring/sampling instances were completed during <br />2001. <br />Foidel Creek: Five surface flow monitoring sites on Foidel Creek in the vicinity of the TCC mine portals and <br />facilities azeas are utilized. Site 800 and site 14 are located upstream of the portal. Flows at site 800 were <br />monitored by the USGS (Station 09243800) in 2001. TCC will take over future monitoring of this site. Site 8 is <br />located a short distance downstream of the portal area and is monitored in conjunction with alluvial we11001-5-5. <br />Site 900 is located further downstream. Site 304 is located further downstream above the confluence with Middle <br />Creek and is monitored in conjuncfion with alluvial we11008-AV-2. Flows at site 900 were also monitored by <br />the USGS (Station 09243900) in 2001. TCC will take over future monitoring of this site. Monitoring <br />requirements at site 304 are limited to monthly water levels and quarterly water quality sampling <br />Tables 39 through 43 provide summaries of the 2001 Water Year data collected at each site. Tables 39a, 40a, and <br />41a provide period of record statistical summaries of collected data at each site. Figures 47, 48, 74 through 81, <br />and 118 through 121 provide graphical representations of water levels and selected water quality parameters <br />• recorded at each site. Typical flow patterns were exhibited at these sites with spring runoff periods accounting <br />for the peak flows observed. At all of these srtes, the inverse relationship between flow and field conductivity <br />continues to be evident. <br />2001 Water quality parameters for drew sites are typically within previously estabkshed ranges. At site 800 <br />(Table 39) new maximum values were recorded for field conductivity was recorded. <br />Fish Creek: Seven surface flow monitoring sites on Fish Creek are utilized. Site 16A replaced site 16 in 2000, <br />and is located upstream of the Fish Creek Borehole discharge site (115). Historical data for site 16 may be found <br />in previous AHRs. Site 307 is located approximately 1 mile downstream of the Fish Creek Borehole mine <br />dewatering site and is monitored in conjunction with alluvial well006-AZ-3. Site 302 is located approximately 2 <br />miles downstream of the Fish Creek Borehole mine dewatering site. Site 1002 is located approximately 4 miles <br />downstream of the Fish Creek Borehole mine dewatering site and is monitored in conjunction with alluvial well <br />006-AW-2. Site 305 is located upstream of the Fish Creek Tipple and is monitored in conjunction with alluvial <br />well 008-AU-3. Site 27A is located near the Fish Creek Tipple. Site 1003 is located downstream of the Fish <br />Creek Tipple. Monitoring requirements at sites 307 and site 305 are limited to monthly water levels and semi- <br />annual field parameters. <br />Tables 44 though 50 provide summaries of the 2001 Water Year data collected at Fish Creek surface flow sites. <br />Tables 44a duough 48a provide period of record statistical summaries of collected data at each site. Figures 58, <br />• 60, 62, and 82 through 101 provide graphical representations of water levels and selected water quality <br />parameters recorded at each site. Again, typical flow patterns were exhibited at these sites with spring runoff <br />10 <br />
