  • Additionally, the authority forbids mining companies from building any structures that require constant human presence in the direct path from a tailings dam, in case it ruptures and its contents flood. Hydro’s vice president of bauxite and alumina at Norsk Hydro Brazil, John Theustad, also a member of the panel discussion, said that Hydro operations are meeting the standards needed from the regulators already. Severe rainfall in Brazil’s northern state of Pará in February 2018 caused concerns over possible water contamination and it led to local authorities ordering Hydro to operate its alumina refinery Alunorte at 50% of its capacity - allegations that Hydro has denied.
