B. Sedimentation Ponds <br />All five sedimentation ponds at the Chimney Rock Mine have been removed and <br />reclaimed in accordance with the approved reclamation plan upon the Division's <br />approval of the Phase II bond release application in July 1998. <br />C. Acid-forming and Toxic-forming Spoil <br />The operator has performed both chemical analyses and leaching studies on samples <br />of the overburden, interburden and coal strata. Based on these analyses, the Division <br />has determined that there is no problem with acid-forming materials or toxic metals at <br />the site. The overburden may affect the salinity and alkalinity of surface waters and <br />ground waters. These effects are expected to be negligible. <br />Details of the chemical characteristics of the overburden, interburden, and coal, as well <br />as greater detail on the geology of the azea, can be found in Sections 2.04.5 and 2.04.6 <br />in Volume I of the approved permit application. All spoil was buried in accordance <br />with the mine plan after it was first exposed on [he mine site (4.05.8(3)). <br />D. hnpoundments <br />All impoundments (five sedimentation ponds) have been reclaimed. <br />E. Surface and Ground Water Monitoring <br />The applicant will resume monitoring of ground water in a manner approved by <br />the Division two years prior to the submittal of a final bond release application as <br />is directed by the approval of Technical Revision 30. The ground water <br />monitoring plan is as follows (4.05.13(1)): <br />Resume the ground water monitoring on the alluvial wells above and below the <br />Stollsteimer Creek AVF. Sample the wells biannually for the following <br />parameters: <br />Water Level Magnesium <br />Ammonia (unionized) Anion <br />SAR Temperature <br />TDS Sulfate <br />Vanadium Calcium <br />Manganese (total and dissolved) <br />Cation pH <br />Conductivity Potassium <br />Sodium Beryllium <br />Lithium Bicarbonate <br />Cobalt <br />Iron (total and dissolved) <br />All surface water monitoring was discontinued with the approval of Technical <br />Revision 30, after the Division had made the determination that pond removal <br />would not negatively impact the hydrologic balance (4.05.13(2)): <br />]0 <br />
