The internal expert task force established to review the Alunorte alumina refinery after the flooding in February has reported preliminary findings.
The status report has the following main findings:
- Discharge of water overflowing from the adjacent waste-water holding pond into the internal open drain, Canal Velho, in addition to the already communicated rainwater release.
- A release of caustic soda inside the plant due to a power failure on February 17. This was mixed with rain water from the factory area before entering the waste-water holding pond, with overflow into Canal Velho.
- Based on the preliminary findings of the task force, Hydro has no indications of leaks or overflow from the bauxite residue deposit areas.
