Previously in October 2009, a panel composed of independent experts and specialists from Brazilian universities and research institutes issued a report on the EIA, finding "various omissions and methodological inconsistencies in the EIA..." Among the problems cited within the EIA were the project's uncertain cost, deforestation, generation capacity, greenhouse gas emissions and in particular the omission of consideration for those affected by the river being mostly diverted in the 100 kilometers long "Big Bend" (Volta Grande).
