• Total vegetative cover will be the cover sampling technique used. Cover data will <br />be collected by species to determine composition and diversity. <br />Production sampling will be done by clipping vegetation in 2.4 sq. ft. quadrants at <br />ground level. Clippings will be bagged, identified, air dried and weighed. Plants <br />rooted in the quadrant (basal concept) will be harvested. All quadrants will be <br />given the same weight since the reference area was chosen for its similarity to the <br />homogeneous range land on which revegetation is being established. <br />Upon completion of the ash disposal operation all waste will be removed or buried <br />to prevent water or visual pollution. Unsalvageable materials will be buried in the <br />pit above ground water level and at least 4 feet below AOC. <br />The final highwalls will be back filled to AOC. There are no acid forming <br />materials in the coat seam as shown in sump water data presented under Section <br />2.04.7 this document. <br />Structures used in the mining operation will be removed, the ground will be <br />topsanded, fertilized, and revegetated. The shale and gravel in the equipment <br />parking area will be removed and buried in the ash pit. The area will then be <br />topsanded, fertilized, and revegetated. <br />• Sealing and Managing Drillholes <br />Drillholes shown on Appendix M-1 have been converted to water monitors, have <br />been mined through, or permanently plugged. <br />Holes that were completed for ground water monitoring purposes are summarized <br />in the McWhorter report (Appendix I, P. 26). <br /> <br />11 fi <br />
