West Elk Mine <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 eazlier in this section. <br />Wetlands <br />The wetlands identified during surveys of the SOD area in 1996 and again in 2004 and reported <br />in Exhibit 32B will be monitored for impacts due to subsidence. A qualified biologist will <br />perform a baseline survey of the wetlands one year prior to those wetlands being subsided. The <br />survey will include transects through the wetlands to document the variety, type and health of the <br />vegetation. These transects will be resurveyed annually for at least two years after the wetlands <br />have been subsided or until it is determined there has been no significant negative impacts to the <br />wetlands due to mining activities. Additionally, wetlands associated with Dry Fork within the <br />reaches of the stream that are part of the thalweg survey will be monitored by the personnel <br />performing the thalweg survey for general changes in vegetation, i.e., wilting, flooding, <br />uprooting, eta If changes are noted and appear to be significant, the Division and Forest will be <br />notified before mitigation efforts, as described in Section 2.05.6(3)(a-i) Protection of <br />Hydrological Balance are implemented. Results of the annual wetland survey and general <br />observations made during the thalweg survey will be included in the Annual Hydrology report. <br />• <br />1.05-297 Revised June 2005 PR/0; Rev.
