<strong>2009</strong> <strong>Annual</strong> <strong>Environmental</strong> <strong>Report</strong><strong>Southern</strong> <strong>Cross</strong> <strong>Operations</strong>Eastern SeepageThe Eastern Seepage is believed to be associated with water flow along the internalembankments between the TSF cells. The water is diverted by the cut off trench underthe eastern embankment of Cell TSF2 through the abutment with Cell TSF1. Improvedmanagement of seepage along the eastern embankment is included as part of theproposal for the southern seepage described above. The trench would be 2-3m deep,backfilled with clean select rock and a geotextile to act as a filter at all trenches.Northern SeepageThe Northern Seepage has effective management and is being controlled. Noadditional seepage management works are being reviewed at this time.25
