Vale informs that, in line with the continuous monitoring of the safety conditions of its geotechnical structures, and as a result of regular inspections and frequent interpretations of data related to the structures, performed through the function of the Engineer of Record (EoR), it started today, on a preventive basis, the Level 1¹ emergency protocol of the Paracatu and Patrimônio dikes, a protocol that does not require the evacuation of the population downstream of the structures.
