GRADING AND BACKFILLING The mine was in some form of continual operation from the mid 1940's to January, 2009. Therefore, with the exception of the newly constructed coal refuse pile, the entire site falls under the Previously Disturbed category. No topsoil was salvaged prior to SMCRA; therefore, not all areas to be reclaimed will receive topsoil. Attempts for 6" of growth medium will be replaced on the Upper Facilities Area, and the refuse pile. The pond area (Area 1) and the Lower Facilities area (Area 2 on Map King I -010) are not scheduled to receive any plant growth medium except that which may lie in and around the areas. The tipple area highwall shown on Map King I -010 will be addressed specifically by Technical Revision 20, to be submitted August 2012 Analysis of stored waste, as tested by C. T. 86 E. is included in Appendix 12(3) (Samples #4, #5 86 #6). Rock lined stilling basins will be constructed at three locations depicted on the fmal contour map (King I -011). The basins will be installed along with the final drainage channels after a successful Phase II Bond release, Volume for reclamation costs estimates are based on surface area delineations as well as grid surfaces calculated from existing and final contour maps using computer software programs. (See reclamation cost estimates for more details) WASTE PILE RECLAMATION Refer to section 2.05.3 (Waste Pile Design) for a detailed description of the coal mine waste (refuse) storage area. Technical Revision TR -08 addresses reconstruction of the waste pile. Designs for this reconstruction have been provided by Don May, P.E. and are located in Appendix 10(1). Upon completion of the reconfiguration of the waste pile as designed in TR -08, fill material was used to cover the face of the pile to the required depth. This fill material was salvaged during reconstruction of the existing waste pile and is composed of about 50% rock and 50% earth. After compaction of this fill material, plant growth medium was spread as required by this section and the area was re- vegetated. This brought the existing face of the pile to final reclamation status. Future waste pile reclamation will entail stockpiling plant growth medium and fill material which will be salvaged while extending the waste pile as it grows. As the waste pile slowly increases in size, all available fill material and plant growth medium will be removed and stockpiled at the east boundary of each 5 year design phase. As the face of the pile rises, material from this stockpile will be drawn upon and used to reclaim the face of the waste pile as outlined above. Should additional fill material be required at final reclamation, suitable material from the designated borrow area will be used. GCC Energy, LLC Section 2.05.4 Page 4 King I Mine August 1, 2012
