II. CRITERIA AND SCHEDULE FOR BOND RELEASE <br /> Phase I <br /> Rule 3.03.1(2)(a) states, "Up to sixty percent of the applicable bond amount shall be released <br /> when the permittee successfully completes backfilling, regrading, and drainage control in <br /> accordance with the approved reclamation plan." The reclamation plan for the Elk Creek Mine <br /> is found in section 2.05.4 of the Permit Application Packet(PAP). <br /> With regard to Phase I bond release,the approved reclamation plan for the Elk Creek Mine calls <br /> for: <br /> • Removal and salvage or demolition and disposal of any surface structures and facilities <br /> not approved for retention to support the postmining land use <br /> • Sealing and backfilling of all mine openings and any wells that will not be retained for <br /> monitoring or water supply <br /> • Regrading of disturbance areas to the approved postmining configuration, with grading to <br /> blend with surrounding undisturbed and previously reclaimed areas and reestablish <br /> effective site drainage <br /> • Construction of designed postmining drainage channels <br /> The following structures were within the footprint of the SL-I parcels and were required to be <br /> demolished: Lamp house; Intake and Belt Portal Structure; Shop; Fuel and Oil storage tank farm; <br /> Wash bay; CV-I Belt Drive Structure, Stack Tubes and Reclaim Tunnel; and portions of <br /> Sanborn Creek's Mine Conveyor system with associated pads and footings. <br /> The applicable sections of the approved reclamation plan state that: <br /> All concrete foundations will be demolished to at least two feet below surface. Prior to <br /> foundation demolition,foundation pads and adjacent areas will be inspected for evidence <br /> ofpetroleum spills or chemical staining and tested, if indicated by inspection,for any <br /> potentially hazardous materials (i.e. hydraulic fluids, antieeze, oils, solvents or similar <br /> materials). Ifno spills or stains are observed, it will be assumed that the areas are clean <br /> and do not require testing. Ifexposed foundations are not contaminated, they will be <br /> rubblized and buried in place or used as backfill either in the reclaim tunnel slot or <br /> against the toe ofslopes during reclamation. If inspection and subsequent testing <br /> indicate contamination, the concrete will either be cleaned, rubblized, and buried on-site <br /> or rubblized prior to removal and disposal at a properly licensed off-site facility. If <br /> foundations are found to be contaminated, areas beneath the foundations will be tested <br /> following foundation removal and appropriate remedial measures (soil removal and <br /> cleaning to eliminate or neutralize contaminants) implemented based on testing results. <br /> Septic systems and associated leach fields will be decommissioned and removed or <br /> backfilled in accordance with applicable local and state requirements at the time of <br /> closure. Buried utilities will be stubbed-off below the postmining grade level and left in <br /> place. <br /> Final backfilling and grading will be completed to create a stable final topography <br /> appropriate to the postmining land use.
