<br /> Pit Operations
<br /> A 7i/z-yard excavator will excavate material from the pit and load the pit run material into 40-ton
<br /> off-road haul trucks. The haul trucks will transport the pit run material to a feed hopper where the
<br /> material will be dumped and fed to a series of field conveyors. The field conveyors will transport
<br /> the pit run material from the pit bottom to the aggregate plant. The feed hopper and field
<br /> conveyors will be moved as new phases are excavated. The series of field conveyors will be
