Middle Creek. Site ]005 (established in 1994) is located downstream of the confluence with Fish Creek and is <br />monitored in conjuncfion with alluvial well008-AT-1. <br />Tables 46 through 48 provide summaries of the 2006 Water Yeaz data collected at Trout Creek surface flow sites. <br />Tables 46a and 48a provide historical summaries of collected data at sites 301, 69, and 1005. Figures 92 through <br />101 provide graphical representations of water levels and selected water quality pazameters recorded at each site. <br />For the most part, typical seasonal flow patterns were observed. 2006 Water quality pazameters For these sites are <br />typically within previously established ranges. <br />Middle Creek: 2006 data for site Site 29, located on Middle Creek below the confluence with Foidel Creek, is <br />provided in Table 49. An historical summary of water quality data is provided in Table 49a. Figures 106 through <br />108 provide graphical representations of water levels and selected water quality parameters recorded at site 29. <br />2006 Water quality parameters for these sites are typically within previously established ranges. <br />3.4 Suoit Saring Monitoring <br />Generally, groundwater migrates along bedding planes, faults, joints, or fracture zones. Given adequate head <br />pressure, if these zones of water migration intercept the surface, a spring or seep results. The TCC spoil spring <br />monitoring program was initiated in 1986 and is conducted annually. In accordance with the approved plan, the <br />annual mine wide survey is conducted during May, with springs measured for flow and field pazameters. If a <br />spring is discharging at or above 35 gallons per minute, it is monitored for the next yeaz in accordance with the <br />monitoring plan. Two spoil spring sites, 7 and the 303 series (303-1 through 303-3), require monitoring under <br />Exhibit 14-10. In addition to the spoil spring monitoring requirements, Spring 7 is monitored quarterly for field <br />parameters, and sampled on asemi-annual basis for water quality (if flowing). In 2006 site 7 did not flow. The <br />303 Spring series is monitored/sampled semi-annually for field pazameters and water quality. <br />Tables 50 through 52 provide summaries of the 2005 Water Year data collected at each 303 series (303-1 through <br />303-3) spoils spring. Table SOa and Sla provide a period of record statistical summary of collected data at sites <br />303-1, and 303-2, respectively. Figure 109 provides a graphical representation of period of record field <br />conductivity for spoil spring 303-1. 2006 water quahty pazameters for series 303-1 are typically within <br />previously established ranges. <br />3.5 Natural Spring Monitoring <br />Two natural springs, SWl and SW2, located over previously mined areas in the Southwest Mining District <br />required semiannual monitoring during 2006. Prior to mining, SW2 typically flowed throughout the year, while <br />SW 1 flows were sporadic. In recent years flows at SW2 have been minor, and in the case of SW 1, non-existent. <br />Minor flows was observed in SW2, in May of 2006. Analytical values were within historic limits. No flow was <br />observed in SW-1 in 2006. <br />11 <br />
