GRADING AND BACKFILLING <br />The mine was in some form of continual operation from the mid 1940's to <br />January, 2009. Therefore, with the exception of the newly constructed coal refuse <br />pile, the entire site falls under the Previously Disturbed category. No topsoil was <br />salvaged prior to SMCRA; therefore, not all areas to be reclaimed will receive topsoil. <br />Attempts for 6" of growth medium will be placed on the Upper Facilities Area and the <br />refuse pile. The pond area (Area 1) and the Lower Facilities area (Area 2 on Map <br />King I-010) are not scheduled to receive any plant growth medium except that which <br />may lie in and around the areas. <br />Analysis of stored waste, as tested by C. T. 8s E. is included in Appendix 12(3) <br />(Samples #4, #5 & #6). <br />Rock lined stilling basins will be constructed at three locations depicted on the final <br />contour map (King I-011). The basins will be installed along with the final drainage <br />channels after a successful Phase II Bond release. Final drainage channels steeper <br />than 5% will be rock lined, others will be grass -lined. Temporary erosion protection <br />(such as erosion mats) will be used until vegetation is established in grass -lined <br />channels. <br />Volume for reclamation costs estimates are based on surface area delineations as <br />well as grid surfaces calculated from existing and final contour maps using <br />computer software programs. (See reclamation cost estimates for more details) <br />WASTE PILE RECLAMATION <br />Refer to section 2.05.3 (Mine Waste Rock Disposal) for a description of the coal <br />mine waste (refuse) storage area. Technical Revision TR -08 addresses <br />reconstruction of the waste pile. Designs for this reconstruction have been provided <br />by Don May, P.E. and are located in Appendix 10(1). <br />Initial reconfiguration of the waste pile is somewhat smaller than as designed <br />in TR -08. The rip -rap rock ditches, Reaches 1 & 10, were constructed to utilize, to <br />the extent possible, equipment that was available at the time of construction. <br />Although unlikely, it is possible that in the future the refuse pile may be enlarged to <br />the "Refuse Pile TR -08 Final Configuration Outline" as show no Map King 1-007. Fill <br />material was used to cover the face of the pile in its current configuration to the <br />required depth. This fill material was salvaged during reconstruction of the existing <br />waste pile and is composed of about 50% rock and 50% earth. After compaction of <br />this fill material, plant growth medium was spread as required by this section and <br />the area was re -vegetated. This brought the existing face of the pile to comply with <br />final reclamation status parameters. <br />Future waste pile reclamation will entail stockpiling plant growth medium and <br />fill material which will be salvaged while extending the waste pile as it grows. As the <br />waste pile slowly increases in size, all available fill material and plant growth <br />medium will be removed and stockpiled at the east boundary of each 5 year design <br />phase. As the face of the pile rises, material from this stockpile will be drawn upon <br />and used to reclaim the face of the waste pile as outlined above. Should additional <br />fill material be required at final reclamation, suitable material from the designated <br />borrow area will be used. <br />GCC Energy, LLC King I Mine <br />Section 2.05.4 <br />Page 4 July 11, 2017 (RN -07) <br />
