Brazilian mining and iron ore regulator, the National Mining Agency, ANM, unveiled on Tuesday details of a new regulation that sets rules for the monitoring of dams, including those with high risk of collapsing.

ANM said miners and iron ore producers are now required to install a dam safety monitoring system in up to 24 months, effectively from July 7, 2020. The regulation was published on Tuesday at the nation’s official gazette, Diario Oficial da Uniao (DOU).

ANM said that the dam monitoring systems will depend on the risk level of dams.

High-risk dams will be required to have an automated instrumentation monitoring system, which should be “adequate to the structure’s complexity,” with real-time and 24/7 monitoring.

Companies shall made information coming from those dam safety monitoring systems available to regulators like ANM, it said.

As for high-risk dams, information, including video-monitoring data should be stored for up to 90 days.
