monitoring schedule. These stations are located along Fish Creek in Sections 5 and 17, T5N, R86W. In <br /> addition to the hydrologic monitoring program, TCC initiated a focused monitoring program for the segment of <br /> Fish Creek to be impacted by mining in the NMD. This environmental program is presented in Exhibit 4e -8, <br /> NMD- Fish Creek AVF Monitoring Program. The program includes the following components: hydrologic <br /> monitoring, vegetation monitoring, and subsidence surveying. <br /> TCC has constructed the 6MN Mine Water Storage Reservoir near the Fish Creek AVF, and completed the <br /> associated mine water supply pipeline across the AVF area and under the Fish Creek channel. Specific Best <br /> Management Practices (BMP's) were utilized during construction of both the Reservoir and pipeline to <br /> minimize any potential for impacts to the AVF. Similarly, potential operational impacts are addressed by <br /> implementation of design BMP's in the constructed facilities, along with regular inspection and monitoring. <br /> Potential infiltration from the Reservoir will be minimized by a designed compacted clay liner with a <br /> permeability on the order of 2.0 x 10 - ' cm/in. Mine water quality is generally compatible with applicable <br /> effluent limits (refer to information for Fish Creek Borehole discharge), and any minor infiltration will mix with <br /> shallow groundwater, and be further diluted before it infiltrates downward or laterally. While there is some <br /> potential for water infiltrating from the Reservoir to reach the Fish Creek alluvium, given the considerations <br /> noted, any potential impacts would be negligible. <br /> • <br /> • <br /> PRO9 -08 2.06 -25.7 04/29/09 <br />
