Vale's PDE3 dam obtains positive DCE and is out of emergency situation
The PDE3 dam, located at the Brucutu mine in São Gonçalo do Rio Abaixo (MG), obtained a positive Declaration of Stability Condition (DCE), certifying the safety of the structure, and its emergency level was closed on last Tuesday (5/9). Since early 2023, three dams have been removed from emergency levels. In addition, eight other Vale structures had their emergency levels closed in 2022. Of the 20 that remain on emergency level, all that have received tailings are inactive and 11 are in the process of being de-characterized. These dams are continuously monitored and receive ongoing actions to improve safety.
The PDE3 dam underwent reinforcement works that confirmed the dam's safety and stability conditions, allowing it to be removed from the emergency level and the DCE to be obtained. The structure contains approximately 70,000 m³ of sediment and was constructed using the single-stage method.
