Trout Creek Alluvial Groundwater: There are two Trout Creek alluvial monitoring wells, 008-AT-1, and a privately owned well (Jones well). Figures 48 through 51 provide graphical representations of water level and field conductivity information to date. Tables 27 and 28 provide 2006 data for these wells. Well 008-AT-1 is monitored in conjunction with surface water site 1005. Figure 48 depicts the water level relationship between these two sites. Monitoring was initiated on Trout Creek Alluvial wells back in 1994. Middle Creek Alluvial Groundwater. TCC has no active Middle creek alluvial wells. Two Middle Creek alluvial wells (AVM-1 and AVM-2) were incorporated into the monitoring network during 1996, however, per TR03-42, these wells were abandoned in the Fall of 2003. Consult previous AHRs for eazlier data. 3.21 Points of Compliance Rule 4.05.13(1)(b) requires Formal establishment of ground water points of compliance for coal operation which has the potential for negatively impacting the quality of ground water for which quality standards have been established by the Colorado Water Quality Control Commission. The Commision's Rule 41 sets forth Basic Standards for ground Water. These Standards are applicable to ground water at [he Foidel Creek Mine. In the judgement of DRMS, these Standazds aze applicable to ground water at the Foidel Creek Mine. However in the judgement of DRMS, the Foidel Creek Mine does not have the potential [o negatively impact bedrock aquifers due to the nature of the geology (i.e. synclinal basin) found at the mine's location. Wells 008-AV-2 (Foidel Creek alluvium), 008-AU-3 (Fish Creek alluvium), and we11008-AT-1 (Trout Creek alluvium) will be established to satisfy alluvial ground water points of compliance. 3.3 Surface Water Monitoring Monitorine/Sampling Requirements: Table 32 presents a summary of surface water monitoring frequencies, which was last updated for Permit Revision 6 (PR 03-06 Exhibits 14-7 through 14-10) in March of 2004. Site locations aze shown on Figure 2 (a.k.a. Map 13A), Hydrologic Monitoring Plan of TR03-42 (as well as in Figure 2 of [his AHR). Table A of Exhibit 14 specifies three seasonal monitoring episodes (i.e. October to Febmary, March to May, and June [o September), each of which are further divided into two general categories of sampling frequency: 1) "Regular" monitoring that is done continuously, and 2) "Contingent" monitoring that is done only when there is a discharge from underground mine pumping at surface discharge sites 109 and/or 115. 2006 surface water data is provided in Tables 33 through 49. 2006 Water quality pazameters for these sites were typically within previously established ranges, unless otherwise discussed below. An historical summary of data through 2006 has been provided in Tables 35a through Sla. Foidel Creek: Four surface flow monitoring sites on Foidel Creek (in the vicinity of the TCC mine portals and facilities areas} aze utilized. Site 800 and site 14 are located upstream of the portal. Site 8 is located a short distance downstream of the portal area and is monitored in conjunction with alluvial well 001-S-5. Site 900 is located further downstream on Foidel above the confluence with Middle Creek. Former site 304 was located further downstream of 900. Site 304 was ehminated in 2003 per TR03-42.
