SURFACE WATER MONITORING <br />Monitoring~pling Requirements (except as noted): Prior to the approval of TR-35 (May 2000), the permit <br />required 12 flow and field parameter monitoring instances [o occur between March and September along with 4 <br />water quality sampling events. Prior to this approval, monitoring/sampling began in the march with extra <br />monitoring and sampling planned to provide the required instances. TR-35 requires only monthly flow and field <br />parameter monitoring, with o~ quarterly water quality sample collection. After the approval of TR-35, the <br />monitoring and sampling schedule was changed to compl}•, and the extra monitoring/sampling was cancelled. As <br />a result, the 2000 Water Year includes fewer surface water moni[oring/sampling instances than normal, however, <br />all re wired monitoring/sampling instances were completed during 2000. <br />Foidel Creek: Five surface flaw monitoring sites on Foidel Creek in the vicinity of the TCC mine portals and <br />facilities areas are utilized. Site 800 and site 14 are located upstream of the portal. Flows at site 800 are <br />monitored by [he USGS (Station 09243SU0). Site 8 is located a short distance downstream of the portal area and <br />is monitored in conjunction with alluvial well 001-5-5. Site 900 is located further downstream. Site 304 is <br />located further downstream above the confluence with Middle Creek and is monitored in conjunction with <br />alluvial well 008-AV-2. Flows at site 900 are also are monitored by [he USGS (Station 09243900). 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 2000 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 sites, the inverse relationship between flow and field conductivity <br />continues to be evident. <br />2000 Water quality parameters for these sites are typically within previously established ranges with a few <br />exceptions. At site 800 (Table 39) new maximum values were recorded for lab conductivity and total recoverable <br />iron. At site 900 (Table 41) new maximum values were recorded for lab pH and carbonate. <br />Fish Creek: Seven surface flow monitoring sites on Fish Creek are utilized. Site 16 is located upstream of the <br />Mine 2 area. Site 307 is located approximately 1 mile downstream of the Fish Creek Borehole mine dewatering <br />site and is monitored in conjunction with alluvial well 006-AZ-3. Site 302 is located approximately 2 miles <br />downstream of [he 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 [he 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 />8 <br />
