through the disturbed permitted station S-1, flow through intermittent. C-1 This surface water monitoring st Coal Bank drainage. It monitors quantity, the flows of which are H-1 This surface Creek. It co information. SC-1 Groundwater Sanborn Creek exists in the area. Like monitoring this drainage is gtion is located in the both water quality and intermittent. water station is located along Hubbard ntinues to provide stream flow and quality well located immediately east of the Mine. It monitors water quality which Rawlins Sandstone Formation. SC-2 Groundwater well located immediately west of the Coal Gulch. It monitors water quality in the Rawlins Sandstone Formation. SC-3 Groundwater well is located next to SC-2 and extends into the "D" Seam coal bed and monitors its water quality. H-10 Groundwater well located at previous upper substation's site along Hubbard Creek. This station monitors water inflow rates and water quality into the sealed mine workings. B-6 Groundwater well located along Bear Creek. It is used to monitor water inflow rates and quality in the "Third Dip" area of the old U. S. Steel Mine. Methods of analysis were consistent with EPA standard testing procedures, the parameters of which are presented in Table 1. The data collected was based on the frequency rates presented in Table 2. Map 1 (#ES-3286) shows locations of the water monitoring points and is included as Appendix 6. The following sections of this report describe the methods and results of the monitoring activities at the Sanborn Creek Mine. SURFACE WATER MONITORING METHODS During quarterly visits, flow measurements were made by measuring the culvert width and water depth. Velocity was then estimated by timing objects over a known distance. In the office, cross sections were drawn to assess change in stream bed configuration and flows were calculated. NF-1, NF-2, U-1, S-1, S-2, C-1, and H-1 water stations were used to gather data for monitoring
