The Seneca II-W Mine does not have any experimental practices or any variances from <br />mountaintop removal or AOC. However, the Division previously granted a variance from contem- <br />poraneous reclamation (see Section Imo. <br />Rule 3.02.2(4) requires that the Division review the amount of the bond and the terms of acceptance <br />of the bond every 2'/z years. <br />This Mid-Term Review consisted of a detailed review of the Seneca II-W Mine permit application <br />and findings document to identify any items that may have been overlooked during the initial <br />review. The Division also reviewed all subsequent revisions and stipulation responses to ensure that <br />all permit commitments and conditions were being followed. Hydrologic monitoring data was re- <br />viewed in conjunction with the review of the application to assess the adequacy of the monitoring <br />plan and discussion of hydrologic impacts. Problems and observations from past inspection reports <br />were also considered. <br />Seneca II-W Mine Page 1 <br />
