RECLAMATION-PLANT GROWTH MEDIUM
<br />•
<br />All stockpiled plant growth medium plus the suitable overburden/sediment
<br />pond material to be used in reclamation will be tested for the following parameters:
<br />1. pH
<br />2. 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 />•
<br />•
<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 Soil De th
<br />Access road and areas not to be
<br />reclaimed None
<br />Pond Area Area 1 None exce t material found durin reclamation
<br />Lower Facilities Area Area 2 None exce t material found durin reclamation
<br />All other areas to be reclaimed U to 6 inches 6 inches minimum on refuse ile
