DNPM publishes new rule concerning dam safety regulations


On May 19th, 2017, the National Department of Mineral Production published a Normative Act (Portaria DNPM n°. 70.389/2017), concerning dam safety regulations.

 The new rule repealed two old acts (Portaria DNPM n°. 416/2012 and 526/2013), after a public consultation held in the DNPM website, and establishes new obligations for mining dams’ owners. Among the major innovations brought by the rule are the obligation of sending biweekly informations concerning the structures through the newly created system (Sistema Integrado de Gestão em Segurança de Barragens de Mineração – SIGBM) and the change of dams’ classification criterea.

The amendments are in line with the inspections’ system improvement proposal, in order to obtain a higher level of security.
