Four more dams were banned by National Mining Agency for lack of stability in the structures. Labourrie, in Amapá, Pirocaua Lagoon, in Maranhão, Basin 07 Alto da Serra, in Mato Grosso do Sul and Serginho Dam, in Mato Grosso. With the new closures, Brazil now has 43 dams banned for this reason. Of these, 36 are in Minas Gerais, one in Pará, one in Amapá and one in Rio Grande do Sul.

The president of the Brazilian Institute for Environmental Protection, Carlos Bocuhy, says that the large number of dams banned is the result of old errors. “What we are going through in Brazil, in fact, is a process of adapting to a series of non-conformities in the licensing of these dams, which led to a very high risk, as can be seen in Mariana e Brumadinho. Firstly, because the environmental licensing of many dams was not carried out in a judicious manner, as it should. Secondly, during the life of these dams, changes were made, enlargements, which allowed for greater instability. So much so that the construction of dams with mining waste itself was recently banned. ”

The new bans were announced after the delivery of the Declaration of the Condition of Stability in last month. The DCE is prepared by the company that owns the dam – delivery is mandatory for the functioning of all structures that are part of the National Dam Safety Policy and must be made in March and September of each year. Despite the advances, Carlos Bocuhy points out that monitoring and inspection of environmental agencies would be safer.

“It cannot be self-declaratory, you have to be subject to inspection and social control. It is difficult to undertake an enterprise in the face of risk. The communities need to give access to this data and the government continues to monitor these developments that pose a risk to populations living nearby. ” Currently, of the 438 dams included in the National Dam Safety Policy, 395 have DCE attesting to stability, 32 have submitted the declaration not attesting the stability of the structures and 11 have not sent the document within the legal period. The latter are automatically prohibited.
