The four (4) water quality samples will be obtained during March, June, August, and September. However, if
<br />:~';treams are ice covered in March, the March sample will be collected during April.
<br />Monitoring of Sites: 302, 301, 69, srrd 1005, will be conducted during the irrigation season only (June-September);
<br />flow and field parameters and water quality will be obtained on a monthly basis during [ha[ time. Sites 14, 304,
<br />305, and 307 are measured from late ~9arch/earl}• April through October for +vater level only. These sites are used
<br />to correlate the stream water level with the water level of the adjacent alluvial wells.
<br />Effluent monitoring consists of water quality and flo+v measurements and is conducted according to the approved
<br />methodology and schedules outlined within the respective permits. Permit CO-0027154 governs the discharge
<br />associated with Ponds B, C, D, E, F and T. Permit CO-0036684 dictates the effluent limitations for Pond E at the
<br />Fish Creek Tipple while Permit CO-0042 ] 61 establishes the effluent limitations for the mine water discharge at the
<br />Fish Creek Dewatering Facility. The NPDES permits are located in Exhibit 30 (Volume III), Exhibit 10 (Voltrrrte
<br />VI11), and Exhibit 44 (Volume IIiA), respectively. Data from the discharge points will be included with the Annual
<br />Hydrologic Report. Additionally, copies of the Discharge 1,lonitoring Report are forwarded to the Division.
<br />Both natural and spoil springs will be monitored within the Foidel Creek Mine permit area. The natural spring,
<br />designated 20-14, is monitored semiannually for both Flow and field parameters and water quality. Spoil spring
<br />monitoring sites include Site 7 and Site 303. Concerning Site 7, a monitoring point has been established in the
<br />channel connecting the Area No. 2 Pit with Pond D. Site 303 is located at the Fish Creek Tipple and is used to
<br />monitor the spoil springs above Pond E. Spring SW-1 and SW-2 are located in the South West mining district.
<br />Site 7 will be included with the annual May spring/spoil spring survey. At the time of the annual survey, flow and
<br />field parameters will be determined and a sample will be collected for analysis of the parameters listed on Table B,
<br />Hydrologic Parameter List. If the flow is equal to or greater than 35 gpm, the site will be monitored for flow and
<br />field parameters in both May and June, then quarterly thereafter, with a full suite analysis being conducted -=1'~= ~`~

<br />. ,emiannually. If the flow is less than 35 gpm, the data collected at the time of the survey will be adequate; no
<br />further monitoring will be done until the next annual survey.
<br />At the Fish Creek Tipple, a composite sample of the spoil springs emanating at the upslope edge of Pond E is
<br />collected and measured semiannually for both a full suite analysis and flow and field parameters. The permitted
<br />area of the Fish Creek Tipple will also be surveyed during the annual spring survey. Sampling of any new spoil
<br />springs will follow the plan: if the flow from a single spoil spring or the combined flow from immediately adjacent
<br />spoil springs exceeds 35 gpm, the spring(s) will be incorporated into the spoil spring monitoring plan. The program
<br />consists of collecting a sample for full suite analysis semiannually and measuring flow and field parameters
<br />monthly during spring runoff and then quarterly thereafter. If the flow is less than 35 gpm, no further monitoring is
<br />required for that water year.

<br />Mine Discharge Monitoring /
<br />Discharge from the underground mine will be sampled at two locations: Site 109 and Site 115. Site 109 is located
<br />near the main portals and the discharge water can be channeled through Pond D or F, prior [o entering Foidel
<br />Creek, or it can be used underground. At Si[e 109, the mine discharge is sampled quarterly for field parameters and
<br />eater quality, and weekly for flow and conductivit}•. Site 115 (FCB Treatment Facility) is located northwest of the
<br />ain portals and serves to dewater the majorit}• of the mine. Water collects in sump rooms and is then pumped up
<br />'io the surface where it is passes through the water treatment facility. The discharge is then channeled to Fish
