- The outer embankment could be constructed by building thin layers (nominally 1 m deep layers placed by trucks, spread by dozer) of compacted NAF waste using bottom up construction techniques;
- The perimeter embankment could be nominally 20to 30 m at the base and 5 to 8 m wide on the crest of the embankment. For the Sub Pit WRSF 20 m benches are proposed and the overall slope will be 20 to 25º;and
- PAF and AF waste should be contained well inside and within the final cover of the dumping site as well asshould not be placed within 5 m of the crest of thefinal embankment.
