Law No. 16.456 providing for the Policy on Transparency in the Operation, Maintenance, and Safety Measures of Dams within the State of Rio Grande do Sul.

This Law establishes the Transparency Policy for the Operation, Maintenance and Safety Measures of Dams in the State of Rio Grande do Sul. The law’s main objective is to strengthen public oversight of dam management by monitoring the actions of the state supervisory authority and ensuring the operational and structural integrity of dams. It seeks to protect communities that may be affected by dam failures through greater transparency regarding the condition, maintenance and safety of these infrastructures. The policy applies to dams located on watercourses under state jurisdiction and complements existing dam safety regulations. To achieve these objectives, the law authorises the state supervisory body to conduct regular inspections, continuous monitoring, preventive maintenance reviews and, where necessary, require structural reinforcement works. It also promotes preparedness through contingency and emergency plans designed to address flood events and minimise socio-environmental damage. In addition, the legislation requires that information on dam conditions, identified anomalies, incidents and accidents be made publicly available in a clear and accessible manner through government communication channels and the Civil Defence website, thereby enhancing transparency, public awareness and risk management.
