Mr. Jared Ebert <br />June 22, 2010 <br />Page 7 <br />4 & 17D ) <br />CIVIL RES")(JRCES <br />Division and notifying the Division if the trigger point is observed. The Operator is encouraged to incorporate <br />portions of the various approved plans for this site if they apply to the current mining and reclamation plan. <br />The Groundwater Monitoring and Mitigation Plan is included in Attachment C. The operator will report <br />monitoring data to the Division as part of its annual report. <br />28) The Division's records indicate a slurry wall has already been installed and approved by the SEO for the former <br />Sharkey Lake area. This appears to be the location of pond C1 and C2. The approved location and <br />configuration of Sharkey Lake slurry wall differs from proposed location of the slurry wall for cells C1 and C2. It <br />appears the Operator is currently dewatering and mining this area. If the current slurry wall is <br />breached/disturbed it would no longer protect the surrounding areas from groundwater drawdown during <br />dewatering. Please explain how this will be handled and how hydrologic balance will be protected. <br />The majority of the slurry wall is located within Cell C1. The proposed slurry wall will be constructed and cross <br />the existing slurry wall at least twice, however this is common practice in slurry wall construction and will not <br />reduce its effectiveness. <br />29) The latest annual report for this site indicates there is a 10.10 acre open water pond. Is wet mining occurring at <br />this site? <br />No, all mining is occurring within the approved slung wall area. The operator is required to augment any <br />depletions through an approved TSSP. <br />6.4.8 EXHIBIT H - Wildlife Information <br />30) Please include the Bald Eagle buffer zone on the Exhibit C map. Please remember that no mining can occur <br />within that buffer zone between November 1St to March 1St per the current approved plan. <br />Please refer to the Mining Plan Map for location of the buffer zone. <br />6.4.10 EXHIBIT J -Vegetation Information <br />31) Are there designated wetlands in new permit area? If so, will they be disturbed and will the applicant need to <br />obtain an Army Corp of Engineers 404 permit? <br />We are working with ERO Resources Corporation to determine if there are any jurisdictional wetlands in the <br />permit area. If there are any jurisdictional wetlands that will be disturbed, the applicant commits to obtaining an <br />US Army Corps of Engineers 404 permit prior to disturbance. <br />6.4.12 EXHIBIT L - Reclamation Costs <br />32) The Division will need to hold a financial warranty to cover the cost to reclaim the current level of disturbance <br />and a projection of the future disturbance. The amount of financial warranty to be held for this site will depend <br />on the applicant's response to several of the questions posed by Division in this review. If the operator chooses <br />a phased approach to this project, the amount of financial warranty can be limited. Exhibit L submitted with the <br />amendment application indicates the worst case disturbance at the site will occur during the construction of the <br />embankment around reservoir C1. Given mining is occurring within portions of reservoir Cl; should the Division <br />assume this will be the initial phase of the operation? <br />Refer to the response to comment 7). <br />33) Exhibit L indicates 330 acres will need topsoil replacement and revegetation. Please explain what these 330 <br />acres will consist of? For example, will this include embankment side slopes, overburden stripping/stockpile
