Vale deploys additional emergency containment measures downstream of the Sul Superior dam

As part of its preventive engineering measures, on Thursday (16/5), Vale began the earthworks for construction of a concrete containment structure located 6 km downstream of the Sul Superior dam, in Barão de Cocais, Minas Gerais, Brazil.

Once completed, this structure will retain most of the volume of tailings from the Sul Superior dam in case of a breach. Vale is also carrying out earthwork interventions, installing containment barriers with metal screens and positioning granite blocks to create a physical barrier to reduce the speed of flow of a potential flood, thus containing the displacement of material within a more restricted area.

The goal is to reduce potential impacts on people and the environment in the extreme case of a breach. The intervention will increase the circulation of trucks and equipment in the city towards the Gongo Soco mine, which may cause possible traffic disturbances.

Vale points out that it continues monitoring the dam and the northern slope of the Gongo Soco pit 24/7 and is working closely with the relevant authorities to warn and inform the entire population about the progress of the works and the situation at both the Sul Superior dam and the Gongo Soco pit.
