are firm. Special compaction equipment will be used if necessary to achieve densities to <br />ensure mass stability, prevent mass movement and prevent formation of voids. The excess <br />material will be compacted to attain 90 percent of the maximum dry density to provide the <br />strength required for stability of the excess material disposal area. Dry densities will be <br />determined in accordance with AASHTO T99 -74. <br />Compaction tests will be taken at a frequency and location of not less than one per every <br />other layer, at random locations across the pile. Test locations and results will be reported to <br />the Division in the appropriate construction reports. <br />Some of the subsoil may be utilized for construction projects at the site. <br />(7) Coal Handling Structures <br />Coal handling structures which NECC will use at the New Elk Mine are shown on Map 11, <br />Surface Facilities and Roads - East Portal.
