SEMAS said it would formally notify the company on Tuesday, 27 February.

In the original resolution from Friday, 23 February, SEMAS ordered Alunorte to reduce the water level in the DRS1 deposit following extreme rainfall on 16-17 February that led to regional flooding.

“We have taken considerable measures to meet the deadline at Alunorte, and we will continue with full force to make sure that we comply with expectations and requirements,” says Hydro CEO Svein Richard Brandtzæg. “We will continue our dialog with local authorities to ensure that we take all necessary steps to ensure safe and sound operations – with respect for people, the environment and for the local communities that we are a part of,” Brandtzæg says.

While it is too early to determine the size and impact of the resolution, it could potentially have significant operational and financial consequences.

Measures implemented at Alunorte to comply with SEMAS’ resolution have led to continuous improvement in the average DRS1 freeboard – the distance between the top of the tailing dam and the water level.

The resolution by SEMAS came after Brazilian environment minister José Sarney Filho expressed similar concerns during a press conference on Monday evening local Brazilian time, calling on the Brazilian Institute of the Environment and Natural Resources (IBAMA) to implement any necessary mitigating actions to remedy the worries about a possible water contamination in the local area, including fines or a possible suspension of activities at Alunorte.

SEMAS also said it would introduce daily fines of around BRL 1 million until Alunorte reached a freeboard of at least 1 meter at DRS1.

Hydro owns 92.1 percent of the Alunorte alumina refinery and 100 percent in the Paragominas bauxite mine.
