Figures 66, and 102 through 111 provide graphical representations of water levels and selected water quality <br />pazameters recorded at each site. For the most part, typical seasonal flow patterns were observed. Due to drought <br />conditions in 2002, some record low flows were recorded. <br />2002 Water quality parameters for these sites are typically within previously established ranges with a few <br />exceptions. At site 301 (Table 51), one new maximum was recorded for laboratory conductivity. At site 69 <br />(Table 52), no new maximum or minimum values were recorded. At site 1005 (Table 53) one new maximum <br />value was recorded for total recoverable zinc. <br />Middle Creek: Two surface sites on Middle Creek are utilized for monitoring flow. Site MC-1 is located <br />upstream of any mining activities and site 700 is located downstream of any mining activities. Flows at site 700 <br />(former USGS Station 09243700) were monitored by TCC in 2002. Note that site 700 was dry in early July <br />through September. Water quality data is provided on Table 54 and 55 with plots of selected data presented on <br />Figures 112 and 117. At MC-1 (Table 54), new maximum values were recorded for dissolved calcium, <br />magnesium, and sodium, as well as bicarbonate and ortho-diss phosphate. The historical summary of flow rate <br />data for selected surface sites is presented as Table 56. This table also provides flow summary information for <br />dischazge sites 62, 109, and 115. <br />3.4 Natural SPrInQ Monitorine <br />One natural spring, 20-14, required semi-annual flow, field pazameter, and water quality sampling during 2002. <br />Spring 20-14 is located in the vicinity of proposed fuhare underground mining areas. As reported in Table 57, no <br />flow was observed at site 20-14 during 2002. Thus, no flow, field pazameters, or water quality samples could be <br />obtained for this site. Monitoring at the site was initiated in 1987 and flows have historically been minor (see <br />Figure 122). Conductivities historically exhibited by the spring aze presented as Figure 123. A statistical water <br />quality summary for the site is presented as Table 57a. <br />Two natural springs, SWl and SW2, located over previously mined azeas in the Southwest Mining District <br />required monitoring during 2002. Quarterly flow, field parameter, and water quality samples are required for <br />these sites. As reported in Tables 62 and 63 no flow was observed at either site SW 1 or SW-2 during 2002. Thus, <br />no flow, field parameters, or water quality samples could be obtained for these sites. Prior to mining, SWl <br />typically flowed throughout the year. SW2 flows were historically sporadic during the period prior to mining. <br />Table 63 provides a summary of data collected at SW2 during the year. TCC will continue to monitor these <br />locations. <br />3.5 Spoil Sprin>i Monitorint=_ <br />The spoil spring monitoring program was hutiated in 1986 and is conducted annually. In accordance with the <br />approved plan, the annual mine wide survey is conducted during May, with springs measured for flow and field <br />• parameters. If a spring is discharging at or above 35 gallons per minute, it is monitored for the next year in <br />accordance with the monitoring plan. Two spoil spring sites, 7 and the 303 series (303-1 through 303-3), require <br />monitoring under Exhibit 14-10. In addition to the spoil spring monitoring requirements, Spring 7 is monitored <br />12 <br />
