1.3 Surface Water Information <br />The data collected from the surface water monitoring stations and laboratory results are <br />presented in Section 3. <br />Surface water monitoring point H-1 is located on Hubbard Creek, where this perennial <br />streams flows through the permit azea associated with the abandoned Somerset Mine. The only <br />current activity in the area has been reclamation of the Lower Hubbard Creek site. <br />H-1, Hubbard Creek, was monitored in April June, August, and October for field <br />parameters. In April and October, the full suite of surface water pazameters in accordance with <br />Technical Revision No. 20 was analyzed. <br />Surface water monitoring points S-1 (Sanbom Creek upstream) and S-2 (Sanbom Creek <br />downstream) are designed to sample the flow in Sanbom Creek above and below the disturbed <br />azea. Sanbom Creek receives dischazge water from the mine. This source of water will cause <br />Sanborn Creek to flow yeaz around, for a distance of approximately 300 feet through culverts <br />under the railroad and highway prior to discharging into the North Fork of the Gunnison River. <br />Monitoring points S-1 flows during the spring run-off and significant precipitation <br />events. The disturbed azea and mine water could effect the quality of water in Sanborn Creek <br />only when there is flow at S-1. For this reason, S-2 is monitored only if S-1 has flow. <br />S-1 was monitored monthly, with flow recorded in March, April and May during spring <br />run-off. Since S-1 had flow, S-2 was also monitored in March, April and May. The quarterly <br />full suite of surface water parameters is scheduled for Mazch, June, September, and December. <br />The full suite of surface water pazameters in accordance with Technical Revision No. 20 was <br />analyzed on S-1 and S-2 in Mazch. <br />P-1 (Portal Drop Inlet) was monitored monthly, with no flow recorded in any month. <br />Since P-1 was dry during the monthly monitoring inspections, there were no samples to analyze <br />for settleable solids. <br />Surface water monitoring points U-1 (Unnamed Drainage) and C-1 (Coal Gulch) are <br />designed to verify [hat the underground mine does not have an adverse effect on the quality of <br />run-off in the Unnamed Drainage or Coal Gulch which are both ephemeral streams. Monitoring <br />results are expected to be similaz to the baseline data. <br />U-1 was monitored monthly, with no flow recorded in any month. C-1 was monitored <br />monthly with flow recorded in March, April, May and June. The quarterly full suite of surface <br />water parameters aze scheduled for Mazch, June, September, and December. A sample was <br />collected in Mazch and June for C-1 and the parameters were analyzed in accordance with <br />Technical Revision No. 20. <br />Surface water monitoring points NF-1 (North Fork upstream), NF-2 (North Fork <br />downstream) and NF-3 (North Fork downstream) are designed to sample the water quality in the <br />North Fork of [he Gunnison River above and below the Sanborn Creek Mine disturbed area. <br />Monitoring results for NF-1 and NF-2 are expected to be similaz to the baseline data, and no <br />significant difference in quality is expected between the upstream and downstream monitoring <br />5 <br />
