Conductivity <br />3. Texture (particle size distribution) <br />4. Sodium absorption ratio <br />5. Saturation percentage <br />6. If pH is over 8, test will be made for selenium and boron. <br />7. Fertilization: <br />Nitrogen <br />Phosphorus <br />Potassium <br />8. Suitability as a plant growth material. <br />Plant growth medium shall be placed to a finished depth of 6 inches over all <br />graded and backfilled areas. Plant growth medium placement operations will be <br />completed in conjunction with processing backfill and grading operations to assure <br />uniform distribution of plant growth medium over all exposed areas. When backfill <br />operations reach a maximum height of 10 vertical feet, plant growth medium shall <br />be applied to that slope area to within 2 feet of the top of the existing bench. Brows <br />or overhangs shall be rounded to conform to the existing surrounding terrain and <br />plant growth medium applied thereto. <br />The bulk of the fill for reclamation of the disturbed mine area will be produced <br />by re -contouring the slopes in such a manner as to leave on the surface those <br />materials determined to be most easily amended to satisfactory plant growth. <br />Additional soil will be taken from a borrow area in the east drainage area below the <br />plateau (Topsoil Borrow Area). For a description of this material and explanation of <br />source and intended disposition see Section 2.04.9 and Appendix 12(3). <br />Coverage of the permit area with plant growth medium for re -seeding and <br />plant growth will be as follows: <br />Location <br />Soil Depth <br />Access road and areas not to be <br />reclaimed <br />None <br />Pond Area Area 1 <br />None (except material found during reclamation <br />Lower Facilities Area Area 2 <br />None (except material found during reclamation <br />All other areas to be reclaimed <br />Up to 6 inches 6 inches minimum on refuse ile)d <br />National King Coal, LLC King I Mine <br />Section 2.05.4 <br />Page 6 February, 2007 <br />
