<br /> of mining,the Phase V IV area would be used as a silt pond. Phase IX VIII will be mined once
<br /> the structures including the aggregate plant are demolished and removed. The material excavated
<br /> from Phase I-X VIII will be processed by a portable plant located on the capped settling pond in
<br /> `, the Phase IV I area. Tables 3-1 and 3-2 describe the elements of the mine phases.
