We stress that the competent authorities are being involved.”
According to the company, after a routine inspection, the technical team identified a crack, centimeters wide, in the dam, “which is common in a structure undergoing reinforcement works”.
“The change to level 1 is preventive and will continue until the presentation of studies and analyzes by the specialized external audit confirming the safety and stability of the dam to the ANM.
