A/HRC/45/12/Add.4 Renova Foundation, and provides technical assistance to support communities exercising qualified participation in these spaces. 63. The CIF is composed of representatives of the Union, the governments of Minas Gerais and Espírito Santo, the impacted municipalities, the affected population, the Federal and State Public Prosecutor's Offices, the Public Defender's Offices of the Union and the States, as well as the Doce River Hydrographic Basin Committee. Presided by Ibama, it brings together about 130 institutions, to guide and inspect the repair of the damages caused by the rupture of the dam in Mariana/MG. 64. The 42 socio-economic and environmental programs established in the TTAC will run until 2031. Eleven Technical Chambers were created, in an advisory capacity, to support the CIF. They are composed of representatives of recognized technical excellence from the institutions that make up the Committee. 65. The Technical Chambers provide advice to the CIF members, supporting the deliberations through studies and technical notes. They also evaluate the program's execution and propose adjustments and corrections to the Committee for the best progress of the reparation and compensation actions. 66. Currently, the CIF meets regularly eight times a year, as does each of the eleven Technical Chambers. All agendas discussed at the CIF are supported by technical notes produced at the TCs, based on their meetings, or by the Renova Foundation's manifestations. 67. Regarding the right to information (p. 16), it should be noted that government actions related to the dam rupture in Mariana were guided, from the beginning, by transparency, with immediate creation, by government entities, of an information portal to society. This principle was also observed in the Transaction and Conduct Adjustment Term. Since the first analyzes of the Fundão dam rupture, environmental agencies have clarified the extent of the impacts. In this sense, an excerpt from Note 01/2016 stands out, which provides the following: Preliminary Technical Report concluded on November 26, 2015, points out that ‘the level of impact was so profound and perverse across the different ecological strata that it is impossible to estimate the time for fauna to return to the site.’ (...) “The strength of the volume of tailings released with the dam rupture may also have revolved and suspended the bottom sediments of the affected watercourses, which, due to the history of use and reports in the literature, already contained heavy metals. 68. Although the data demonstrated that the type of material deposited in the dam was preliminarily inert, Ibama warned, on its page, that the passage of the tailings wave could have revolved contaminants present in the bed and on the banks of the affected rivers, highlighting the expected impacts in every stretch of the Doce River basin. 69. Regarding the studies on the impacts on human health, it should be noted that the hiring of Ambios company was based on a term of reference validated by the Health Technical Chamber. It is an advisory body for CIF decisions, composed of professionals from States Health Secretariats and the Ministry of Health. It is pointed out that, as explained in Technical Note ‘CT-Saúde 11/2017’, the Human Health Risk Assessment Study (EARSH) aims to define contaminants of interest, routes of exposure and exposed population to guide the Epidemiological and Toxicological Studies, and therefore not as an end in itself. 70. Once the final report is available, health agencies start a technical evaluation. It may request clarifications, point out inaccuracies, make recommendations, and even request complementing the information presented in the document so that EARSH fulfills its objective of guiding health and monitoring population follow-up studies actions. The CIF Deliberation that determined the preparation of the Study 106 established as references the Guidelines of the Ministry of Health and the Minimum Bases document from the ‘CT-Saúde.’ 71. After the assessment, actions and strategies are developed to preserve the citizens' health. In the process of elaborating these measures, Public Authorities' action consists of making information available in a timely and reasonable manner. 72. It is further clarified that, in September 2018, CIF Deliberation 197 revoked the Renova Foundation's determination of intellectual property on Epidemiological and 11
