Dam monitoring has become a widely discussed issue throughout Brazil, especially after the accidents in previous years. On July 7, 2020, the ANM released a new resolution on the monitoring of tailings dams. In this resolution, the ANM began to mandate the use of automated monitoring systems in dams with high potential associated damage.
The resolution was published in the Official Gazette and amends the part of the 2017 ordinance that created the National Registry of Mining Dams and the Integrated Safety Management System for Mining Dams.
With the resolution published, it becomes mandatory for the entrepreneur to implement a monitoring system in tailings dams if his dam fits the conditions mentioned in the resolution.
