West Elk Mine <br />• West Elk Mine lease azea severely hamper sampling procedures and influence the collection of <br />meaningful data. As a result, by restricting sampling to the periods of flow and ensuring sample <br />integrity, MCC will be able to provide meaningful data to the Division while reducing the costs <br />associated with collecting unnecessary data or data that is not meaningful. <br />MCC has selected the water quality parameters above and as outlined in Table 7 for routine <br />measurement because they are most commonly associated with coal mining impaction on water <br />quality. Annual, full-suite monitoring will allow MCC to identify possible mining-induced changes <br />in water quality. Monitoring data, along with a discussion of any impact observed or projected will <br />be provided and will be submitted by April 30 each year. Based on information presented in <br />previous AHRs, groundwater quality, as observed from monitoring wells, has not been impacted by <br />mining activities. <br />Surface and underground protection measures for groundwater aze presented in Section 2.05.6(6}. <br />Augmentation and other mitigation measures for surface water rights that may be impacted are <br />presented earlier in this section. <br /> <br />• <br />2.03-237 RevisedNwembes 2004PR10 <br />
