• E-1-Lower Elk Creek Surface water monitoring point E-1 -Lower Elk Creek, an ephemeral drainage, is monitored as a down gradient site to verify that the Elk Creek mine and the surface facility located at Somerset does not have an adverse affect on the quality of runoff in the drainage. Due to the prevailing drought conditions, during 2004 there was, again, minimal stream flow at E-1. An analysis of the limited data suggests there is no adverse impact of the Elk Creek mine to Lower Elk Creek. E-2- Upper Elk Creek Surface water monitoring point E-2 -Upper Elk creek, an ephemeral drainage, is monitored to verify that the Elk Creek mine does not have an adverse affect on the quality of runoff in the drainage. In addition, the site will serve as an up-gradient site to monitor Elk Creek prior to entering the OMLLC surface facility. Due to the prevailing drought conditions, during 2004 there was, again, minimal flow at E-2. S-1 - Unper Sanbom Creek and S-2 -Lower Sanborn Creek Surface water monitoring points S-1 -Upper Sanborn Creek and S-2 -Lower Sanborn Creek were established to monitor the flow in ephemeral Sanbom Creek above and below the disturbed area of the Sanborn Creek Mine site. Sanborn Creek also received discharge water from the Sanborn Creek mine, consisting primarily of natural mine water inflows and some runoff of • imported (from the North Fork intake) water from the mining sections. The mine water discharge (CDPS discharge point 011) commingled with upper Sanborn Creek flow for a distance of approximately 300 feet through culverts under the railroad and highway prior to discharging into the North Fork of the Gunnison River. The S-2 sample site is located at the outlet of the culvert, prior to the confluence with the river. Because of the closure of the Sanborn Creek mine, and the termination of discharge point 011, the S-2 sample site was no longer needed and, thus, eliminated from the OMLLC hydrologic monitoring program. (TR-45). Sanbom Creek, an ephemeral stream, flows at monitoring point S-1 during spring runoff and significant precipitation events. During 2004, S-1 had minimal flows and by mid-June flows had ceased altogether. C-1 -Lower Coal Gulch Surface water monitoring point C-1 -Lower Coal Gulch, an ephemeral drainage, is monitored to verify that the Sanborn Creek mine does not have an adverse affect on the quality of runoff in this drainage. Due to prevailing drought conditions, during 2004 there was, again, minimal flow in Coal Gulch. NF - 1 and 3 -North Fork of the Gunnison River Surface water monitoring points NF-1 (North Fork upstream) and NF-3 (North Fork . downstream) were selected to monitor the water quality in the North Fork of the Gunnison River above and below the disturbed surface mine site of the Sanborn Creek and Elk Creek Mines. Monitoring point NF-3 was established in September 1997 to monitor mining-related water quality impacts from the West Valley coal refuse pile. It should be noted that NF-3 is also
