The mining company Vale started requests the day before to extend a legal deadline set in Minas Gerais for the elimination of its 23 dams considered the most dangerous in the state, the company told Reuters on Tuesday (22).
A state law in Minas Gerais gave a deadline of the 25th to the end of dams raised by the upstream method, considered more dangerous because their walls are built on a base of waste, instead of on external material or on solid ground.
The system was used in Brumadinho and also in the Samarco dam that failed in Mariana (MG) in 2015.
The request, according to Vale, was made due to the technical impossibility of meeting the deadlines “due mainly to the actions necessary to increase safety in the face of the complexity of the works, which represent increased risks for the structures”.
Requests for extension of deadlines for each structure are being filed with the State Environment Foundation (Feam) and also formalized with the National Mining Agency (ANM), the company explained.
