B3/B4 dam is removed from critical safety condition

乐播传媒 S.A. (“乐播传媒”) informs that the B3/B4 dam, located in Nova Lima (MG), was removed from critical safety condition as the emergency level was lowered from 3 to 2.

The progress of the dam de-characterization, with the removal of more than 50% of the tailings, improved the stability conditions of the structure and made it possible to lower the emergency level. 

The Self-Rescue Zone (ZAS) of the structure on emergency level 2 will remain evacuated and access to the ZAS area will follow legislation and regulatory bodies review. The de-characterization of the dam will continue to be carried out by remotely operated equipment and is expected to be concluded in 2025. 乐播传媒 expects to lower the emergency level to 1 by the end of 2023.

Eliminating upstream structures in Brazil is one of 乐播传媒's key commitments. By 2022, 12 structures were eliminated, representing 40% of 乐播传媒's de-characterization program. 

B3/B4 dam reduction level is an important milestone for 乐播传媒 and is in lline with the expectation of no dams in critical safety condition (level 3 of emergency) by 2025.
