• Foidel Creek flows adjacent to the TCC Foidel Creek Mine surface facilities and receives treated effiuent from a <br />series of sediment ponds established at the facility. Mine site drainage is controlled through seven (7) sediment <br />ponds (Ponds T, B, C, D, E, F, and G -see Figure 2). Mine water is discharged from the mine and routed <br />through Pond D prior to being discharged to Foidel Creek. The Fish Creek drainage is located north of the Foidel <br />Creek Mine surface Facilities azea and overlies tracts, which have been longwall mined. Mine water is also <br />discharged into Fish Creek via the Fish Creek Borehole facility (dischazge site 115). Former surface operations at <br />the Fish Creek Tipple site, and south of the TCC Foidel Creek Mine, have been reclaimed and released from <br />bond. <br />Surface coal mining has been conducted in the azea since the 1960's. The Fish Creek Tipple site was constructed <br />in 1974, and ceased operation in 1983. The Foidel Creek Mine was later established in 1983, and is on-going <br />operation. The Foidel Creek Mine portals are faced-up in the down dip high-wall of the strip mine. Hydrologic <br />monitoring was initiated by CYCC in 1979. TCC continues the monitoring program under updated DMG permit <br />requirements, which is discussed in the next section. <br />Since mid-1987, hydrologic monitoring and reporting has primarily been conducted by TCC persormel. In May <br />of 1995, a private firm (Miller Water Monitoring Service) was contracted to assist with hydrology monitoring at <br />the TCC sites, and continues to assist in monitoring to date. Prior to June 1986, water quality analyses were <br />performed by the on-site CYCC laboratory. From 1987 to 2000, water quality analyses were primarily performed <br />by ACZ Laboratories (formerly Bookcliffs) of Steamboat Springs, Colorado. Beginning in 2001, water quality <br />• analysis has primarily been performed by C.T.&E. of Denver, Colorado. <br />Three surface water sites addressed in this report (USGS 09243700, USGS 09243800 and USGS 09243900) were <br />monitored for flow by the US Geologic Survey (USGS). Prior to the 1989 Water Yeaz, the USGS also collected <br />and analyzed water quality samples from these sites. Since the 1989 Water Year, TCC collects water quality <br />samples for subsequent laboratory analysis. Begimuug with the 2002 water year, TCC has taken over monitoring <br />of these three sites from the USGS. <br />3.0 2001 HYDROLOGIC MONITORING PROGRAM <br />Specific monitoring site locations and their elevations are shown on Figure 2. Required monitoring frequencies <br />and associated parameter lists can be found in Permit No. C-82-056, Exhibit 14. 2001 data collected at each <br />monitoring site is presented as Tables 1 though 55 and 57 through 71. Data measurements from 2001, which aze <br />above or below previously documented data ranges have bcen highlighted in these tables. Table 56 provides a <br />historical summary of flow rate data for the surface water monitoring sites. Table 72 provides low-quality coal <br />haulage figures for 2001. Figures 3 through 133 provide graphical representations of selected data. Figure 134 <br />presents data documented during the 2001 Mine Inflow Study. Statistical summaries of the historical data base <br />aze provided after presentation of the 2001 data. Statistical summaries of water levels or flows aze presented as <br />well. Figwe 135 provides the location of Foidel Creek, in relation to panels 12 right (12 Rt), and 9 Rt through 6 <br />Rt. Figure 136 provides the Middle Creek profile over panels 2 Rt through 6 Rt. <br />
