en.Wedoany.com Reported - Vale has completed the decharacterization of the B7A dam at the Águas Claras Mine (MAC) in Nova Lima, located in the Belo Horizonte Metropolitan Region (RMBH). This dam is the third structure at the mine to undergo the decharacterization process. The initiative is part of the Mine Closure Environmental Plan (PAFEM), which outlines solutions and timelines for the safe closure and reintegration of related structures into the environment. Through intervention measures, the structure no longer functions as a dam, and accumulated water and sediment have been removed.

Angélica Silva, General Manager of Geotechnical Engineering at Vale, stated that this achievement reinforces the company's commitment to the safety of people and the environment, as it continues to advance dam decharacterization projects. The company has initiated work on the B6 dam, expected to be completed in the second half of 2027, with on-site interventions aimed at achieving the same objectives as the B7A, ensuring the structure no longer functions as a dam.

According to the mining company, the decharacterization of the 8B dam and the auxiliary dike of Dam 5 at MAC has been completed, while structures 7B and 5 MAC are in the project development phase. These structures are decommissioned and were built using single-stage or downstream construction methods. Until the projects are completed, these dams will continue to undergo regular inspections and 24-hour monitoring by Vale's Geotechnical Monitoring Center (CMG).
