approximately two additional cubic yards of concrete. The site was then backfilled. The repair was successful <br />and the pipe is no longer leaking and the location is dry and stable. <br />Discharge from the North Mine workings ceased in 1999 when mining ceased and the pumps were shut down. <br />The mine was subsequently sealed and backfilled, and future discharge is not anticipated, based on projected <br />final ground water elevation. There is infrequent discharge from sedimentation ponds. All discharge from <br />sediment ponds and the underground workings is sampled and reported in accordance with CDPS and DMG <br />permit requirements. For additional information on these discharges, see Section C.II. of this document. <br />General Reclamation Summary <br />The approved reclamation plan requires that reclamation of most areas is to begin upon cessation of mining. <br />Some locations including the lower benches of the Cameo Refuse Disposal Sites and the North Decline were <br />reclaimed in the mid-1990's. Final reclamation of remaining facility areas and refuse pile areas was initiated in <br />2000, with extensive earthwork and revegetation completed during 2002. Reclamation activity is continuing, <br />with most major tasks to be completed by the end of 2009. Initial tasks include removal of structures and <br />facilities, and sealing of underground openings. Following completion of structural demolition in a specified <br />location, the area is backfilled and graded to approved configuration. Topsoil is redistributed on most <br />reclaimed surfaces, and all reclaimed areas are seeded and mulched. Roads not approved for postmining use <br />will be removed when no longer needed for reclamation activities. Details of the reclamation plan are included <br />in Tab 14 of the approved permit application package. <br />Mine entries and ventilation shafts are sealed with concrete and at least ten feet of non-combustible material, or <br />simply backfilled with 25 feet of non-combustible material in accordance with procedures specified in the <br />approved permit. Drill holes and monitoring wells will be filled with drill hole cuttings or sealant and plugged <br />with cement. <br />Disturbed areas other than refuse areas will be backfilled to approximate original contour, with the exception <br />of a designated portion of the South Portal facilities area, for which the Division (within Permit Revision No. <br />3) approved a Steep Slope Variance from Approximate Original Contour, to allow for retention of facilities to <br />support an alternative "Industrial or Commercial" postmining land use. The reader is referred to Section <br />B.VIII of the Proposed Decision and Findings of Compliance for PR-3 dated July 30, 2007, for findings <br />specific to the approval of the Steep Slope Variance from Approximate Original Contour, and to Section B.X <br />of that document, for findings specific to proposed approval of the alternative "Industrial or Commercial" <br />postmining land use at the South Portal facilities area. There are no plans for retention of highwalls. <br />With PR-4, the Division proposes to approve an alternative "Industrial or Commercial" postmining land use for <br />the Unit Train Loadout area. See Section B.X of this document for specific fmdings applicable to approval of <br />the alternative postmining land use. <br />Refuse areas will be compacted and graded to final design contours and covered with the required thickness of <br />non-toxic, non-combustible material (24" on CRDA-2, 18" on RSRDA, and CRDA-1). This cover thickness <br />includes topsoil. <br />Temporary roads will be reclaimed when no longer needed for access during reclamation activities. All roads <br />will be reclaimed with the exception of roads approved for the postmining land use (listed in Section B.I. of <br />this document). Roads will be ripped, cuts and fills returned to approximate original contour, and the entire <br />surface regraded. <br />Permit Revision No. 4 11 February 3, 2009
