Planned Removal Actions
Continue with removal efforts in the Mill facility and Mill Pond.

Next Steps
- Continue Vac truck operations in pump/thickener level, followed by return to comminution/flotation level and upper levels.
- After structural modifications of coarse ore bin are completed, ore will be removed with excavator and staged at the existing on-site ore stockpile area in accordance with agreement achieved during 11/25/02 conference call.
- Oversize material and other material that Vac truck cannot remove efficiently to be removed manually by G.L.Palm personnel.
- START prepare Site-Specific Sampling Plan for confirmation sampling.


Key Issues
- Slow progress resolving coarse ore bin removal difficulties.
- Delay of Demolition Work Plan.
- Resolution of scheduling for completion of decontamination and initiation of confirmation sampling and demolition activities.
